(OMNNI) assisted the City of Oshkosh with inspecting the outfalls in the City’s municipal separate storm sewer system (MS4) for potential illicit discharges. Following the Illicit Discharge Ongoing Inspection Program that was developed in 2009, OMNNI inspected 97 of the approximately 357 MS4 outfalls identified in the City, including 16 outfalls that were re-screened due to potential illicit discharges in 2011. The inspections consisted of a visual screening along with a chemical analysis of any dry-weather flow that was present. The inspections revealed nine outfalls with evidence of potential illicit discharges. In addition, OMNNI responded to three requests by the City to investigate potential illicit discharges. In all three cases, OMNNI found evidence of potential illicit discharges. The Ongoing Screening Program calls for approximately 86 outfalls to be inspected in 2013, which will complete the first four-year inspection cycle. At the conclusion of that cycle, future outfall screenings may continue the existing four-year cycle, or may be modified with a revision and WDNR approval of the Ongoing Screening Program. BACKGROUND Purpose Under Section 2.3.3 of the Wisconsin Pollutant Discharge Elimination System (WPDES) Permit No WI-S050075-1 (“permit”), the City of Oshkosh is required to conduct ongoing dry weather field screening of all outfalls during the term of the permit to detect potential illicit discharges. Under the MS4 permit, an outfall is defined as “the point at which storm water is discharged to waters of the state or leaves one municipality and enters another.” The MS4 is defined as “a conveyance or system of conveyances including roads with drainage systems, municipal streets, catch basins, curbs, gutters, ditches, constructed channels or storm drains, which meets all of the following criteria: 1. Owned or operated by a municipality. 2. Designed or used for collecting or conveying storm water. 3. Which is not a combined sewer conveying both sanitary and storm water.” When applied to the City of Oshkosh, the MS4 permit requires ongoing screening of the road ditch or storm sewer outfalls where the outfalls discharge to a water of the state (i.e., a navigable or non-navigable stream, lake, or wetland) or where they discharge into an adjacent municipality or to a county or state highway right-of-way. OMNNI assisted the City of Oshkosh with developing a four-year ongoing screening program in 2009, and completed the ongoing screening program for the first set of outfalls in 2010. This report summarizes the results of the third year of the ongoing field screening program. The City may need to include these results in the annual report required by the MS4 permit due March 31, 2013. Outfall Identification and Mapping In 2009, the City of Oshkosh identified major and minor outfalls within the city as part of the MS4 mapping process required by the permit. Outfalls were identified at the locations where March 25, 2013 2 2012 Ongoing Screening Summary Report City of Oshkosh the City’s MS4 discharged to a water of the state, to an adjacent municipality, or outside the permitted area. Approximately 348 potential outfalls were identified during this process in 2009. (The number has changed since then, due to construction of stormwater detention basins, reconfiguration of the City’s storm sewer system, and reevaluation of existing outfalls.) Topographic information was also used to define approximate drainage basins for each outfall. Based on this information, each outfall was classified as “major” or “minor.” A “major outfall,” as defined by the MS4 permit, is an MS4 outfall that meets one of the following criteria: 1. A single pipe with an inside diameter of 36 inches or more or equivalent conveyance (cross sectional area of 1,018 square inches) which is associated with a drainage area of more than 50 acres. 2. A single pipe with an inside diameter of 12 inches or more or equivalent conveyance (cross sectional area of 113 square inches) which receives storm water runoff from land zoned for industrial activity with 2 or more acres of industrial activity, but not land zoned for industrial activity that does not have any industrial activity present. Outfalls not meeting the definition of a major outfall are considered “minor outfalls.” OMNNI has also worked with the Wisconsin Department of Natural Resources (WDNR) to develop a third class of outfalls – “supplemental” outfalls. Supplemental outfalls are storm sewer outfalls which may not meet the definition of an outfall according to the MS4 general permit, but should be included in an ongoing field screening program. The majority of the supplemental outfalls are detention basin inlets, which do not discharge directly to a water of the state, and therefore are not technically outfalls. However, sampling the detention basin inlets is an important component of the overall screening process, as illicit discharges are more likely to be discovered at the detention basin inlets rather than at the detention basin outfall. When necessary, field verification was used to determine outfall sizes or drainage patterns. The current outfall map includes 106 major outfalls, 235 minor outfalls, and 16 “supplemental” outfalls. These numbers are updated each year as outfalls are located during the ongoing field screening program and modifications are made to the MS4. A map showing the MS4 outfalls is included in Appendix A. Initial Screening Program Per Section 2.3.2 of the MS4 general permit, the City was required to conduct an initial field screening at all major outfalls during dry weather periods. This initial field screening was required to be conducted within 36 months of the date that the permit was issued. The minor and supplemental outfalls should be included in the ongoing field screening to be conducted in future years. OMNNI conducted the initial field screening for the City of Oshkosh during the summer of 2009. During the initial field screening, 109 major outfalls throughout the City were inspected. (There has been a net decrease of three major outfalls since the initial field screening due to changes in the storm sewer system and field confirmation of measurements.) The initial field screening revealed 24 major outfalls that showed evidence of a potential illicit discharge. The results of the initial field screening were presented to the City in the City of Oshkosh Initial Field Screening Summary Report (May 18, 2010). Development of Ongoing Screening Program Section 2.3.3 of the MS4 permit requires municipalities to develop an ongoing screening program and submit it to the WDNR within 36 months of the date that the permit was issued. March 25, 2013 3 2012 Ongoing Screening Summary Report City of Oshkosh The ongoing screening program must include provisions to include all outfalls (major, minor and supplemental) at least once during the 5-year permit cycle. In developing the program, consideration should be given to the hydrological conditions, total drainage area, population density, traffic density, age of the structures or buildings in the area, history of the area, and land use types. Based on the MS4 permit requirements and other information obtained from WDNR, OMNNI developed a proposed ongoing screening program for the City of Oshkosh. The permitted area was divided into four inspection districts, each with approximately the same number of outfalls. One district would be inspected each year, resulting in a four-year inspection cycle. At the end of the first inspection cycle, the inspection results are to be evaluated to determine if the inspection cycle for each outfall should be adjusted. The proposed ongoing screening program was presented to the City in the CITY OF OSHKOSH IDDE O NGOING FIELD SCREENING PROGRAM (May 19, 2010). OMNNI conducted the first round of ongoing screening inspections during the summer of 2010 and the second round of inspections was conducted during the summer 2011. The third round of inspections was conducted during the summer of 2012, and the results are included in this report. The 2012 inspection district is shown in more detail in Appendix A. Screening Methodology OMNNI’s outfall screening methodology loosely follows the procedures outlined in ILLICIT DISCHARGE DETECTION AND ELIMINATION : A GUIDANCE MANUAL FOR PROGRAM DEVELOPMENT AND T ECHNICAL ASSESSMENTS (Center for Watershed Protection / Robert Pitt, October 2004). The procedures were modified to comply with the MS4 permit requirements, and have evolved after several years of experience. Outfalls that have been previously inspected are located with the assistance of GPS. For outfalls that have not been previously inspected, the available MS4 mapping is used to physically locate the outfall, and then the GPS location is recorded to assist with future inspections. The physical properties of the outfall are then recorded – type of outfall, dimensions, material, and discharge location. A photograph of the outfall is taken to show the general location and configuration. After the physical properties have been recorded, the outfall and surrounding area are screened for indicators of current or past illicit discharges. Sample indicator parameters include floatable material, gross solids, odors, stains, color of water, turbidity, abnormal vegetation and benthic growth. If any of these physical indicators are observed, they are further described and quantified. A close-up photograph is taken of the actual discharge of the outfall, showing any indicator parameters or flow from the outfall. A short video of the flow is also taken to document the magnitude of the flow or the lack of flow at the time of inspection. The MS4 permit specifies that the outfalls be screened during periods of dry weather. Outfall inspections are typically conducted in the summer months to avoid the effects of snowmelt runoff in the storm sewer system. OMNNI generally waits for a minimum of 72 hours following a runoff-producing rainfall event to conduct the outfall screening. This typically allows sufficient time for the stormwater to discharge through the drainage area and outfall. If, after 72 hours, the outfall still has flow, a sample is collected and screened for chemical indicators of an illicit discharge. While the actual list of chemical parameters is specific to each outfall, most flowing outfalls are screened for the following parameters: March 25, 2013 4 2012 Ongoing Screening Summary Report City of Oshkosh pH Chlorine (total chlorine and free chlorine) Copper Detergents Phenols (for outfalls in basins with industrial sources) Ammonia Temperature Conductivity The list of chemical parameters was developed using the parameters that were required for the initial field screening in the MS4 permit (listed in bold), and supplemented with additional parameters that are useful for tracking illicit discharges. In some cases, outfalls can be either partially or fully submerged. A partially submerged outfall is an outfall where the elevation of the invert is below the water level of the receiving water. A fully submerged outfall is a pipe that is entirely below the water surface. In either condition, the water is “backed up” into the discharging pipe or channel, and is not free-flowing. Under these conditions, if a sample is collected at the outfall point, the sample could consist almost entirely of the receiving water. In the case of partially or fully submerged outfalls, OMNNI developed a sampling procedure that was approved by WDNR. The submerged outfall is screened for physical indicators. However, the flow sample is collected from the first access point (i.e., manhole, catchbasin, curb inlet) upstream of the outfall. This reduces the influence of the receiving water. Typically, if there is no flow or pooled water at the upstream location, then no sample is collected. For all upstream sampling, a note is made of the distance and land use of the area between the outfall and the upstream area to assess the potential for illicit connections between the outfall and the upstream location. In the event that the physical or chemical indicators show that there is a potential ongoing illicit discharge, the Illicit Discharge Coordinator of the municipality is contacted. If requested, OMNNI then assists the municipality with attempting to identify the source of the discharge, usually by inspecting and/or sampling additional upstream points to attempt to isolate a particular branch of the MS4 network. Due to the history of significant floatable debris in many of the upstream manholes, OMNNI conducted a preliminary inspection of the upstream manholes in May 2012. The purpose of this inspection was to locate the upstream manholes and identify any manholes with significant floatable material. A list of the manholes with floatable material was provided to the City following the inspection so that the manholes could be cleaned prior to the actual ongoing screening inspection. The results of these preliminary inspections were typically not included in the numbers and charts included in this summary report, unless a full screening was conducted with no additional follow-up actions required. While not explicitly required by the MS4 permit, OMNNI also conducts a physical condition assessment for each outfall. The inspector identifies any graffiti, damage, erosion or deposition present at the outfall and assigns a severity. This information is provided to the municipality to assist with maintenance activities. A detailed outfall report is generated for each outfall that is inspected. The outfall report includes the general outfall information that was collected, along with detailed inspection March 25, 2013 5 2012 Ongoing Screening Summary Report City of Oshkosh results for each inspection conducted at the outfall. This provides a comprehensive history of the inspection results for the outfall as multiple inspections are performed over the life of the outfall. Detailed inspection reports for each outfall are included in Appendix B. Some general observations from the field screening are noted in the following sections. Additional Outfall Screening In addition to the 81 outfalls identified in the 2012 district for the ongoing field screening program, 16 outfalls from the 2011 inspection area were also re-screened in 2012. These outfalls had potential illicit discharges identified during the 2011 ongoing field screening program. The outfalls that were re-screened are listed below: Table 1 - 2011 outfalls re-screened under the 2012 program Outfall Classification Reason 01-132 Potential Severe floatable debris in upstream manhole (from 2010 program) 01-520 Potential Severe floatable debris in upstream manhole (from 2010 program) 02-322 Potential Low pH in upstream manhole 02-357 Potential Severe floatable debris in upstream manhole 03-22 Potential Severe floatable debris in upstream manhole (from 2010 program) 03-35 Potential Severe floatable debris in upstream manhole (from 2010 program) 06-1694 Potential Moderate floatable debris and oil sheen in upstream manhole (from 2010 program) 06-221 Potential Moderate floatable debris in upstream manhole (from 2010 program) 09-101c Potential Moderate floatable debris in upstream manhole (from 2010 program) 11-512 Potential Severe floatable debris in upstream manhole 11-803 Potential Ammonia detection in upstream curb inlet 14-582 Obvious High ammonia and chlorine concentrations in flow in upstream manhole (from complaint) 14-676 Potential Persistent suds where outfall discharges to stream (from 2010 program) 16-142 Potential Floatable debris in upstream manhole (from 2010 program) 16-201 Potential Floatable debris and petroleum sheen in upstream manhole (from 2010 program) 16-463 Potential Floatable debris in upstream manhole (from 2010 program) These outfalls were screened in the same manner as the other outfalls in the 2012 inspection area. These outfalls are included in the outfall reports in Appendix B and the maps included in Appendix C (if applicable). Any suspected illicit discharges that were identified in these outfalls during the 2012 re-screening are included in the Potential Illicit Discharges section of this report. March 25, 2013 6 2012 Ongoing Screening Summary Report City of Oshkosh RAINFALL AND FLOW Rainfall Weather data was obtained from the Weather Underground website. Personal weather station KWIOSHKO10 (“Northeast Oshkosh”) is located near the intersection of Nicolet Avenue and Bowen Street in the City of Oshkosh. The conditions at this weather station were considered representative of the weather in the City of Oshkosh for the 2012 inspection area. The weather history from May 1 through September 30 is shown in Figure 2.

March 25, 2013 8 2012 Ongoing Screening Summary Report City of Oshkosh Figure 3 - Rainfall history and outfall inspections Flow To meet the requirement of dry weather screening, outfalls were typically screened at least 72 hours after the previous runoff-producing rainfall event. Despite this time period, 5 of the 97 inspected outfalls had dry weather flow, as described below: Table 2 - Observed flow intensity at outfalls Outfall Flow Intensity 06-880 Trickle 16-646b Trickle 16-844 Trickle 06-622a Moderate 13-409 Substantial (Note that if the outfall was partially or fully submerged, it is not included in this list. Submerged outfalls, along with the observed flow patterns, are described in the next section.) March 25, 2013 9 2012 Ongoing Screening Summary Report City of Oshkosh The distribution of the flow intensity of the outfalls is shown in Figure 4. Figure 4 - Flow intensity at outfall If dry weather flow was found during the field screening, a sample was collected and analyzed for the presence of indicator parameters. The analysis conducted is discussed in a later section. Not all flow is an indicator of an illicit discharge. Following a significant rainfall event, surface water and groundwater elevations can be higher than normal. Much of the observed flow may originate from sump pump discharges, detention basin discharges, permitted discharges, and infiltration into the storm sewer system. Submerged Outfalls Most of the outfalls in the City were located at or below the normal levels of their respective receiving waters. Of the 97 inspected outfalls, 38 were partially submerged, and 25 were fully submerged (Figure 5). Of the 25 fully submerged outfalls, 18 could not be physically located. March 25, 2013 10 2012 Ongoing Screening Summary Report City of Oshkosh Figure 5 - Submerged status of outfalls As shown in Figure 4, of the 61 submerged outfalls, 18 could not be located, two had no flow, five had slight flow, and 36 had indeterminate flow. The submerged flow was classified as “indeterminate” if there were no physical or visual indications of flow within the submerged pool, but it was not possible to definitively rule out flow (i.e., by observing dry sections directly above and below the submerged pool). Submerged outfalls were screened at a representative upstream location (i.e., first upstream manhole), if one was available. If flow or a submerged pool was present in the upstream location, a sample was collected. If a representative upstream location was not available, a sample was collected from the submerged pool at the outfall. PHYSICAL INDICATOR ASSESSMENT All outfalls, regardless of whether they exhibited dry-weather flow at the time of inspection, underwent an extensive assessment for physical indicators of past or current illicit discharges. The physical indicators are grouped into eight categories, and each category is assigned a severity rating based on the observed conditions, along with a qualitative description, if applicable. The eight categories of physical indicators are described below. Floatables Floatables include situations like petroleum sheens, suds, algae, and evidence of raw sewage. These conditions would typically be observed in an area of stagnant water, such as a downstream pool or an upstream manhole, although some may be observed in the actual flow. Some conditions (petroleum sheens and sewage) are almost always the result of an illicit March 25, 2013 11 2012 Ongoing Screening Summary Report City of Oshkosh discharge. Other floatables, like suds and algae, can have non-illicit sources, but their presence can also indicate the potential for an illicit discharge, and the source should be traced. Vegetative debris and solid waste (litter) can also float, but these substances are included in the Gross Solids category, and are not considered floatables. A slight severity for floatables indicates isolated occurrences of the substance in the pool or flow. A moderate severity indicates a broader coverage, including distinct pockets of the substance. A severe classification typically describes total coverage of the water surface. Odor Clean stormwater should have no odor. Odors may be caused by the presence of chemicals, which can indicate a potential illicit discharge. The classification of odor is somewhat subjective, and may vary depending on the inspector. Some of the odor classifications are chemical-based, and include petroleum, VOC/solvent, chlorine, and sulfur. Other odor classifications are more subjective, and include musty, fishy, sewage, and fragrant. Odor can be difficult to quantify. As a result, the severity is based on the method that it can be detected. A slight severity for odor indicates that the odor can be detected in the sample bottle. A moderate severity indicates that the odor can be detected in the flow itself. A severe classification indicates that the odor can be detected from a distance. Turbidity Turbidity is a measure of the clarity of a water sample, reflecting the amount of suspended solids present in the water. As turbidity increases, the water becomes cloudy and eventually opaque. Turbidity has a negative impact on aquatic life, as it prevents sunlight from penetrating the water. Turbidity is frequently caused by soil erosion that occurs upstream of the outfall. The soil erosion can be accelerated by poor erosion control management practices. Active construction sites and highly eroded areas are common sources of turbidity. While turbidity can be measured directly using an instrument like a turbidimeter, the relative turbidity of each outfall sample was assessed qualitatively. A slight severity for turbidity indicates that the sample appeared slightly cloudy in the sample bottle. A moderate severity indicates that the sample exhibits significant cloudiness. A severe classification was used for a sample that was opaque in the sample bottle. Color Stormwater typically should be clear, with no apparent color. Certain tints and colors can indicate the presence of substances that could be a potential illicit discharge. Some tints can be caused by natural substances, such as tannins in leaves and vegetative debris causing a slight brown tint. High concentrations of suspended solids can cause orange tints (clay), brown tints (loam) or gray-black tints (organic materials). Certain colors (i.e., red, blue and green) are almost never naturally-occurring, and likely indicate an illicit discharge. Color is most easily assessed in the sample bottle. The sample bottle can be compared to a bottle of deionized water as a standard. The general color of the sample is noted, along with the relative severity. A slight severity for color indicates that the color is faint in the sample bottle. A moderate severity indicates that the color is easily detected in the sample bottle. A March 25, 2013 12 2012 Ongoing Screening Summary Report City of Oshkosh severe classification indicates that the color can be observed in the actual flow or pool, outside of the sample bottle. Vegetation The health of the vegetation in the area surrounding the outfall can be an indicator of potential illicit discharges from the outfall. Various chemicals in an illicit discharge can inhibit or kill the vegetation in the areas surrounding the outfall. Discharges with high nutrient levels – particularly fertilizer runoff – can significantly increase the amount of vegetation around the outfall. Because outfalls provide a water source, the vegetation around outfalls is typically more productive than areas farther from the outfall, particularly during dry periods. It is important to distinguish between increased vegetation due to available water and excessive vegetation due to nutrients in the runoff. True vegetation impacts due to chemicals or nutrients appear to be rare compared to other physical indicator parameters. The “vegetation” indicator parameter does not apply to vegetation growing inside the outfall pipe or on the pipe apron. This condition is evaluated under the “benthic growth” parameter. Vegetation effects were classified as either “inhibited” or “excessive.” The severity was subjectively assigned based on the extent of the vegetation impact that was observed, ranging from slight to severe. Benthic Growth Due to the presence of nutrients, organic materials and moisture, outfall pipes and aprons can commonly host vegetation that grows on the sides and bottoms of the structures. This is particular common in concrete pipes, which are more porous, but can occur on nearly all pipe materials. The vegetation encountered is typically algae, moss and lichens. Some degree of benthic growth is present on nearly all storm sewer outfall pipes, and appears to increase with age. The presence of benthic growth alone is not typically a reason to classify an outfall as a potential illicit discharge. However, severe cases of benthic growth, especially when combined with other indicators, can be used to classify and trace illicit discharges. The color of the benthic growth is noted on the inspection report. Green benthic growth is most common in outfalls with sunlight. Brown benthic growth is more common in outfalls with limited sunlight. Other colors, such as orange, can sometimes be present. The severity of the benthic growth is determined by a subjective analysis of the thickness of the vegetation. A slight severity for benthic growth indicates a thin layer, usually a film or the dried stains of former growth. A moderate severity is used when an actual depth of vegetation can be observed, typically up to one-half inch deep. A severe classification is used when the vegetation changes from a short, “fuzzy” layer to longer, more defined plants with stems and leaves. Stains Stains inside pipes, aprons, riprap and channels can be good indicators of past illicit discharges. Clean stormwater typically would not cause stains. However, some non-illicit discharges can cause stains, including tannins from vegetation (brown), road salt (white), minerals (various colors) and suspended solids (gray or brown). Most storm sewer pipes will have some degree of staining due to natural causes, and the stains tend to increase with age. These stains are typically found at either the normal or the high flowline for the pipe. March 25, 2013 13 2012 Ongoing Screening Summary Report City of Oshkosh Abnormal stains are typically indicators of past illicit discharges. Common types of stains in this category include oil and grease, paint, concrete washout, and iron discharges (rust). It is important to distinguish between actual iron discharges and normal pipe corrosion, which can occur in metal pipes, and is not an illicit discharge. Corrosion typically occurs along the invert of the pipe, where water may collect and corrode the pipe. Rust stains are typically darker streaks, often originating from a lateral or other incoming pipe. Stains are useful indicators, since they tend to be persistent, and can often be used to trace the flow path upstream to a source, even after the original illicit discharge has ended. By screening outfalls on a regular basis and documenting the stains with photographs, it is possible to compare the severity of the stains to determine if a discharge is ongoing. Stains are classified according to the type of stain present (i.e., oil, paint, rust, etc.), as well as their relative severity. The severity is subjectively assigned based on the extent of the staining that was observed, ranging from slight to severe. Because of the subjective nature of this rating, photographs are extremely helpful for documentation. Gross Solids The Center for Watershed Protection adopted the concept of Gross Solids in regards to illicit discharge detections. Gross solids are materials that are larger than fine solids (silt and clay) and coarse solids (fine sand, fine gravel, and detritus). Gross solids consist primarily of litter (human derived trash larger than 4.75 mm), organic debris (leaves, branches, seeds, twigs and grass clippings larger than 4.75 mm), and coarse sediments (inorganic breakdown products from soils, pavement or building materials greater than 0.075 mm). The type of gross solid most frequently encountered during outfall inspections appears to be litter (garbage). These materials typically enter the storm sewer from an upstream catchbasin or inlet. Paper, plastic and foam are frequently encountered in manholes, where they can become trapped as they float on the surface. These materials can also travel down storm sewer pipes and swales, ultimately discharging at the outfall. Vegetative debris, including leaves and grass clippings, can also enter the storm sewer through catchbasins and inlets and travel to the outfall. As with litter, an attempt is made to determine if the vegetative debris traveled through the storm sewer or was deposited at the outfall in another manner. Coarse sediment is encountered less frequently than litter and vegetative debris. Most of the sediment encountered during outfall inspections is fine sediment that travels through the storm sewer and is deposited at the outfall. This sediment is included in the “Deposition” category of the Physical Condition Assessment on the report, and the sediment depth is recorded. Sediment is typically only considered a Gross Solid physical indicator parameter if it appears that the sediment was illicitly dumped into the storm sewer through a catchbasin, inlet or manhole. Gross solid severity is similar to the method used for floatables. A slight severity for gross solids indicates isolated occurrences of the substance in the pool or flow. A moderate severity indicates a broader coverage, including distinct pockets of the substance. A severe classification typically describes total coverage of the water surface or manhole. Observed Conditions The presence of any physical indicators in the pipe or channel, flow, downstream pool, and surrounding area were recorded at the time of the inspection. Certain physical indicators, such March 25, 2013 14 2012 Ongoing Screening Summary Report City of Oshkosh as color and turbidity, can only be evaluated if flow or downstream pools are present. (Because the inspection criteria for physical indicator parameters have evolved over the past several years, some of the parameters included in the current year’s inspections may not have been evaluated in previous years, and those parameters may appear as blank or missing data on earlier reports.) The presence of one or more physical indicator parameters does not necessarily indicate that an illicit discharge is occurring or has occurred in the past. Certain physical indicators, such as the presence of solid waste or oil sheens in the flow, strongly suggest an illicit discharge has recently occurred. Other indicators, such as staining of the pipe or channel, may indicate that an illicit discharge occurred in the past, although the exact time is not known. Still other physical indicators may have natural or non-illicit causes, and the presence of these parameters alone should not be the grounds for assuming an illicit discharge. Physical indicators can also be valuable aids when tracing a suspected illicit discharge upstream to the source. Certain physical indicators – pipe and channel stains in particular – are persistent and can be used to trace the flow well after the actual flow has stopped. The physical indicators observed during the outfall inspections are summarized in Figure 6. Figure 6 - Physical indicator observations Benthic growth (green and/or brown) and flowline stains were prevalent at many of the outfalls. These conditions are fairly common, and are not typically considered strong indicators of recurring illicit discharges unless they are particularly severe. Five outfalls were classified as potential illicit discharge because of the presence of gross solids in their upstream manholes. These outfalls are discussed in more detail in the Potential Illicit March 25, 2013 15 2012 Ongoing Screening Summary Report City of Oshkosh Discharges section of this report. No other outfalls were classified as potential illicit discharge solely due to physical indicators. CHEMICAL ANALYSIS When dry-weather flow is present at an outfall or upstream manhole, chemical indicator parameters can provide valuable information about whether the flow is an illicit discharge, as well as providing clues about the potential sources of the flow. Section 2.3.2.2 of the general permit requires that outfalls with dry-weather flow be sampled for pH, total chlorine, total copper, total phenol and detergents for the initial screening of major outfalls, unless detergent, ammonia, potassium and fluoride were used as alternate parameters. Under section 2.3.3, the ongoing screening of all outfalls could be modified to include other parameters. For the ongoing screening program, OMNNI tested for the following chemical indicators: pH Temperature Conductivity Chlorine (total and free) Copper Ammonia Detergents Phenols (for drainage basins with industrial areas) Flow samples were collected at all outfalls that exhibited dry-weather flow at the time of the inspection. For partially-submerged or fully-submerged outfalls, a sample was collected from the flow or submerged pool at the first upstream sampling location. A total of 54 stormwater samples were collected and analyzed as part of the ongoing screening process in 2012 – 9 from flow streams and 45 from pools. Depending on the specific conditions for the outfall, not all tests were run for all samples. The indicator parameters, testing methods, and results are explained in the sections that follow. pH Background The pH of a stormwater sample can be used to detect the presence of illicit substances in the flow. Neutral water has a pH of 7.0. However, unpolluted rainwater commonly has a pH of 5.0 to 6.0, due to the conversion of carbon dioxide in the atmosphere to carbonic acid. The presence of pollutants in the atmosphere can cause the formation of additional hydrochloric and/or nitric acid in the rainwater, which will further lower pH. The pH of the runoff is typically raised as it reacts with carbonates and other alkaline materials in the rocks and soil. Contact with concrete pipes and channels also raises the pH of the runoff. March 25, 2013 16 2012 Ongoing Screening Summary Report City of Oshkosh The typical pH range for stormwater runoff is from 6.0 to 9.0. Samples with a pH lower than 6.0 or higher than 9.0 would be suspect for illicit discharges. Possible sources of high or low pH include industrial discharges and concrete truck washout. Testing Method During the ongoing screening program, OMNNI tested the pH of the outfall samples with an Oakton PC-10 handheld pH/conductivity/temperature meter, which displays the pH reading to 0.01 pH units. The probe was periodically calibrated at 4.01, 7.00 and 10.01 pH values. The pH reading was taken in the sample bottle as soon as possible after the sample was collected from the outfall, as the pH of the sample can change over time. Results The pH results for the pH samples are shown in Figure 7. Figure 7 - pH sample results The pH values ranged from 6.91 to 8.73. None of the samples were outside the typical pH range, so none of the samples were considered suspect due to pH. Temperature Background While not included in the list of parameters required by the general permit, the temperature of a stormwater sample can be useful in determining if the flow is originating from an illicit source. Because most stormwater is conveyed in underground pipes, the temperature of the flow at the outfall is typically expected to be similar to the ground temperature which is often cooler than the ambient temperature in summer. However, stormwater that passes through open channels or ponds upstream of the outfall can be heated directly by the sun, and may be close to ambient temperature or even slightly warmer. Temperature is normally only a consideration when the runoff is significantly lower than the ground temperature or higher than the ambient March 25, 2013 17 2012 Ongoing Screening Summary Report City of Oshkosh temperature, which can indicate the presence of an industrial discharge. For example, cooling water or process water is typically significantly warmer than the ambient temperature. Ground temperatures were typically 55 degrees or warmer in summer. As a result, the “normal” temperature range was set at 55 to 90 degrees. Any samples outside of this range could contain flow other than stormwater runoff. Testing Method During the ongoing screening program, OMNNI recorded the temperature of the outfall samples with an Oakton PC-10 handheld pH/conductivity/temperature meter, which displays the temperature reading to 0.1 °C. The temperature reading was taken in the sample bottle at the same time the pH was tested, as soon as possible after the sample was collected from the outfall, as the temperature of the small volume of the sample container will rapidly change. Results The temperature results for the samples are shown in Figure 8. Figure 8 - Temperature sample results The temperature values ranged from 58 to 81 °F. The samples with the highest temperatures were collected from locations that could be influenced by solar heating, so the upper values were not considered suspect. None of the samples exhibited abnormal temperatures, so none of the samples were considered suspect due to temperature. Conductivity Background While not included in the list of parameters required by the general permit, the conductivity of a stormwater sample can be useful in determining if the flow is originating from an illicit source, and identifying potential sources of the discharge. Conductivity is a measure of the ability of water to pass an electrical current. The presence of inorganic dissolved solids (chloride, nitrate, March 25, 2013 18 2012 Ongoing Screening Summary Report City of Oshkosh sodium, calcium, iron, etc.) can increase the conductivity of a water sample. Organic compounds (oil, alcohol, sugar, etc.) are not good conductors, and therefore have relatively low conductivities. Conductivity in surface water is influenced by the local geology. Streams that run through granite bedrock tend to have lower conductivity because granite is composed of more inert materials that do not ionize when washed into the water. However, streams that run through areas with clay soils tend to have higher conductivity because of the higher ionizing potential of clay. Sanitary sewage can raise the conductivity due to increased levels of chloride, phosphate and nitrate. Conductivity is typically measured in siemens, with a typical unit of microsiemens per centimeter (µS/cm). Distilled water has a conductivity in the range of 0.5 to 3 µS/cm, while rivers typically have conductivities ranging from 50 to 1500 µS/cm. Conductivity readings above 2000 µS/cm can sometimes be associated with industrial discharges.1 Conductivity values under 2000 µS/cm were considered to be normal. Samples with conductivities over 2000 µS/cm were identified as suspicious, but the discharge was not considered a potential illicit discharge unless other indicator parameters (physical or chemical) were observed. Testing Method During the ongoing screening program, OMNNI recorded the temperature of the outfall samples with an Oakton PC-10 handheld pH/conductivity/temperature meter, which displays the conductivity reading to 0.01 µS/cm. The conductivity reading was taken in the sample bottle as soon as possible after the sample was collected from the outfall, as the conductivity of the sample can change with temperature. Results The conductivity results for the samples are shown in Figure 9. 1 USEPA: Water-Monitoring & Assessment – Conductivity (http://water.epa.gov/type/rsl/monitoring/vms59.cfm) March 25, 2013 19 2012 Ongoing Screening Summary Report City of Oshkosh Figure 9 - Conductivity sample results The conductivity values ranged from 170 to 5,050 µS/cm. Two outfalls – 13-1219 US1 (2,830 µS/cm) and 16-844 (5,050 µS/cm) were above the 2,000 µS/cm level for suspected industrial discharges. However, neither outfall had other abnormal physical or chemical indicators, so they were not considered suspect due to conductivity alone. Outfall 16-844 had been installed shortly before the outfall screening was conducted, so clay, concrete dust, and other construction materials could be temporarily raising the conductivity in the sample. Chlorine Background The presence of chlorine in a stormwater sample usually demonstrates the presence of substances other than stormwater runoff. Chlorine is typically an indicator of either potable water (from a chlorinated municipal water supply) or an industrial discharge. It can also be caused by leaking or draining swimming pools. However, chlorine can also be present in non- illicit discharges (as defined by the general permit and the City’s illicit discharge ordinance), including residential car washing, lawn irrigation, hydrant flushing, water main breaks, and industrial discharges regulated under a WPDES permit. Therefore, the presence of chlorine in a sample indicates the presence of a non-stormwater source; however, the source should be identified to determine if it is an illicit discharge. Dissolved chlorine is measured using three different values: free chlorine, combined chlorine, and total chlorine. Free chlorine represents the “unbound” chlorine molecules in solution, which are the most effective for disinfecting. Combined chlorine represents the chlorine molecules that are bound to other organic molecules, such as chloramines, which are also commonly used in drinking water disinfection. Total chlorine represents the sum of the free chlorine and the combined chlorine. The general permit requires sampling for total chlorine. Action levels were established by OMNNI for most chemical indicators. A test result that exceeds the action level warrants follow-up investigation. In general the action level for total March 25, 2013 20 2012 Ongoing Screening Summary Report City of Oshkosh chlorine is set at 0 mg/L. Any detection of chlorine indicates the presence something other than stormwater in the sample. Depending on the source, it may or may not be an illicit discharge. Testing Method During the ongoing screening program, OMNNI tested the outfall samples for total chlorine and free chlorine using Hach Free & Total Chlorine Test Strips, 0-10 mg/L. These test strips had result steps of 0, 0.5, 1, 2, 4 and 10 mg/L. The chlorine tests were taken in the sample bottle as soon as possible after the sample was collected from the outfall, as chlorine can dissipate over time. Results None of the samples tested positive for free chlorine or total chlorine, so none of the samples were considered suspect due to chlorine. Copper Background The presence of copper in stormwater runoff is usually due to discharge from industries that manufacture copper-based products or use copper-containing chemicals in their manufacturing process. In some cases, copper can leach from plumbing systems and enter the water. Copper concentrations as low as 0.1 mg/L can be toxic to aquatic vegetation and wildlife. The general permit requires sampling for total copper. In general the action level for total copper is set at 0 mg/L. Any detection of copper indicates the presence something other than stormwater in the sample. Testing Method During the ongoing screening program, OMNNI tested the outfall samples for total copper using Hach Copper Test Strips, 0-3 mg/L. These test strips had result steps of 0, 0.2, 0.5, 1, and 3 ppm. The copper tests were taken in the sample bottle as soon as possible after the sample was collected from the outfall. Results None of the samples tested positive for total copper, so none of the samples were considered suspect due to copper. Ammonia Background While not included on the list of required parameters in the general permit, ammonia is a valuable test parameter to identify potential illicit discharges. Besides being present in industrial discharges, ammonia can also be an indicator of wastewater or washwater discharges, which are often indicators of sanitary sewer cross-connections. When tested along with potassium, it is possible to use the ratio of ammonia to potassium to distinguish between wastewater and washwater. However, since both typically originate from sanitary sewer, this determination is not usually required to identify an illicit discharge. It should be noted that there are also several natural sources of ammonia which do not constitute an illicit discharge. Waste from pets and wildlife can cause ammonia in the runoff, particularly if wildlife frequently inhabit the storm sewer pipes and manholes. Storm sewers connected to stagnant water or wetlands frequently have elevated ammonia levels due to March 25, 2013 21 2012 Ongoing Screening Summary Report City of Oshkosh microbial decay of plant and animal proteins. In addition, ammonia may be present in industrial discharges with a WPDES permit. Because of the natural sources of ammonia, the action level for ammonia detections was set at greater than 1 ppm. Samples with ammonia concentrations of 1 ppm or lower were not investigated unless additional chemical or physical indicator parameters were present. Testing Method During the ongoing screening program, OMNNI tested the outfall samples for ammonia using Hach Ammonia (Nitrogen) Test Strips, 0-6.0 ppm. These test strips had result steps of 0, 0.25, 0.5, 1, 3, and 6 ppm NH3-N. The ammonia tests were conducted in a separate vial of stormwater taken from the sample bottle as soon as possible after the sample was collected from the outfall, as the ammonia concentration can dissipate over time. Results The ammonia results for the samples are shown in Figure 10. Figure 10 - Ammonia sample results The ammonia values ranged from 0 to 3 ppm. Several samples were at or below the 1 ppm action limit. Based on other factors, those outfalls may or may not have been classified as potential illicit discharges. The illicit discharge potential of the outfalls with ammonia detections are summarized in Table 3. Table 3 - IDDE potential of outfalls with ammonia detections Outfall Ammonia (ppm) IDDE Potential Reason 01-520 US1 0.5 Potential Persistent gross solids in manhole (not classified due to ammonia) 02-322 US1 3 Potential Sewer odor in manhole; elevated pH in 2011 March 25, 2013 22 2012 Ongoing Screening Summary Report City of Oshkosh Outfall Ammonia (ppm) IDDE Potential Reason 06-2241 US1 0.5 Potential 3 ppm ammonia concentration during pre- screening – may be influenced by the receiving water 13-1716 US1 3 Potential High levels of detergent (1.3 mg/L) in manhole, possibly from car wash trench drain 13-409 0.5 Unlikely Sample collected from outlet of South Park detention basins. No elevated ammonia in inlets to basin. Abundant waterfowl in and around pond. 16-1508 US1 1 Potential 3 ppm ammonia concentration during repeat screening The outfalls that were considered potential illicit discharges are discussed in more detail in the Potential Illicit Discharges section of this report. Detergents Background The presence of detergents in the outfall sample is usually an indication of the presence of wastewater and/or washwater. This is typically the result of a sanitary sewer cross connection. However, detergent can also be present in non-illicit discharges (as defined by the general permit and the City’s illicit discharge ordinance), including runoff from residential car washing. Therefore, the presence of detergent in a sample indicates the presence of a non-stormwater source; however, the source should be identified to determine if it is an illicit discharge. There are four main classes of detergents: Anionic detergents (negatively charged) – Common in dishwasher detergents, liquid and powdered laundry detergents, carwash detergents, and shampoo. Anionic detergents have excellent cleaning properties and high sudsing potential. Cationic detergents (positively charged) – Used for germicides, fabric softeners and emulsifiers. Cationic detergents have poor cleaning properties by themselves, but can help anionic detergents be more effective. Nonionic detergents (ionically inert) - Common in hand dishwashing liquids, household cleaners, and laundry detergents (especially in combination with anionic detergents). Nonionic detergents are excellent grease removers. Amphoteric detergents (negatively or positively charged, based on pH) – Found in shampoo and cosmetic products due to their mild chemical nature. Amphoteric detergents are also found in hand dishwashing liquids due to their high sudsing potential. Unfortunately, due to the diverse classes of detergents, there is no single test to detect the presence of all detergents. The most common test – the Methylene Blue Active Substances (MBAS) test – is only effective in identifying the presence of anionic detergents. March 25, 2013 23 2012 Ongoing Screening Summary Report City of Oshkosh The general permit requires sampling for detergents. In general the action level for detergents is set at 0 mg/L. Any detection of detergent indicates the presence something other than stormwater in the sample. Depending on the source, it may or may not be an illicit discharge. Testing Method During the ongoing screening program, OMNNI tested the outfall samples for detergents using MBAS method with the equipment and reagents provided in the Hach Stormwater Test Kit. This is a colorimetric test method in which the intensity of the color in the reagent can be used to estimate the anionic detergent concentration. In most cases, a clear result indicates no detergent in the sample, and a blue tint indicated a positive detection of detergent. In some samples with high turbidity, the MBAS test method results in foam or bubbles in the solution. These bubbles have no impact on the overall test result, and if the bubbles and solution are clear, the result is a negative test for detergent. No Detergent Present Detergent Present Turbidity Bubbles, No Detergent Present Figure 11 – Typical MBAS Detergent Test Results Because of the equipment and reagents (including chloroform) used in the MBAS test, the detergent test was conducted in the office at the end of the day. OMNNI’s experience with samples that have tested positive for detergent show that little dissipation occurs within 48 hours of testing, so same-day testing for detergents was an acceptable approach. Results The detergent results for the samples are shown in Figure 12. March 25, 2013 24 2012 Ongoing Screening Summary Report City of Oshkosh Figure 12 - Detergent sample results The detergent values ranged from 0 to 1.3 mg/L. Manhole 06-489 US1 had a trace detection of detergent (0.25 mg/L) during the June inspection. No other physical or chemical indicators were present, and no detergent was detected during the September follow-up inspection. As a result, this detection was not classified as a potential illicit discharge. Manhole 13-1716 US1 had a fairly high detergent concentration (1.3 mg/L), along with an ammonia concentration of 3 ppm. Because of these detections, 13-1716 US1 was classified as a potential illicit discharge, and is discussed in more detail in the Potential Illicit Discharges section of this report. Phenols Background The presence of phenol in stormwater runoff is usually due to discharge from industries that use phenol-containing chemicals in their manufacturing process. These industries include chemical, textile, paint, resin, tire, plastic, electronics and pharmaceutical manufacturing. Phenol can also occur naturally in the groundwater in some areas. The general permit requires sampling for phenol. Because of its limited sources, the Ongoing Screening Program submitted to the WDNR proposed that phenol only be tested for outfalls with industrial sources in the drainage basin. In general the action level for phenol is set at 0 mg/L. Any detection of phenol indicates the presence something other than stormwater in the sample. Testing Method During the ongoing screening program, OMNNI tested the outfall samples for phenol using the equipment and reagents provided in the Hach Stormwater Test Kit. This is a colorimetric test method in which the intensity of the color in the reagent can be used to estimate the phenol March 25, 2013 25 2012 Ongoing Screening Summary Report City of Oshkosh concentration. In most cases, a clear result indicates no phenol in the sample, and an orange tint indicated a positive detection of phenol. Because of the equipment and reagents used in the phenol test, the phenol test was conducted in the office at the end of the day. No dissipation of the phenol was expected within 24-48 hours of collecting the sample. Results None of the samples tested positive for phenol, so none of the samples were considered suspect due to phenol. POTENTIAL ILLICIT DISCHARGES After examining the presence of physical indicators at each outfall and any chemical indicators present in the stormwater samples, each outfall was assigned one of the following classifications, in order of increasing likelihood of the presence of current or past illicit discharges: Unlikely – no significant physical or chemical evidence of current or past illicit discharge Potential – presence of physical and/or chemical indicators, but no strong visible evidence Obvious – visible and/or strong chemical evidence of current or past illicit discharge Of the 97 inspected outfalls, 88 were classified as unlikely and 9 were classified as potential. The outfalls that were classified as anything other than “unlikely” are summarized in the table below and discussed in more detail in the following sections. A map showing the locations of these outfalls is included in Appendix C. Table 4 - Outfalls with elevated illicit discharge classifications Outfall Classification Reason 01-132 Potential Persistent gross solids in upstream manhole (also present in 2010 and 2011). 01-520 Potential Persistent gross solids in upstream manhole (also present in 2009, 2010 and 2011). 02-322 Potential Elevated ammonia and sewer odor; elevated pH in 2011. 03-22 Potential Persistent gross solids in upstream manhole (also present in 2009, 2010 and 2011). 03-35 Potential Persistent gross solids in upstream manhole (also present in 2009, 2010 and 2011). 06-829 Potential Persistent gross solids in upstream manhole. 06-2241 Potential Elevated ammonia (3 ppm) in upstream manhole. 13-1716 Potential Elevated detergent (1.2 mg/L) and ammonia (3 ppm) in manhole. 16-1508 Potential Elevated ammonia (3 ppm) in upstream manhole. The number of outfalls identified with potential illicit discharges slightly less than 2011. A chart showing the number of outfalls inspected over the past four years (starting with the initial screening in 2009) and the number of potential or obvious illicit discharges is shown in Figure 13. March 25, 2013 26 2012 Ongoing Screening Summary Report City of Oshkosh Figure 13 - Illicit discharge potential of inspected outfalls Upstream Manholes with Significant Floatable Debris During the 2011 ongoing screening program, 11 upstream manholes contained significant amounts of floatable debris (gross solids), including plastic bottles, foam packaging, and other solid waste, and were classified as potential illicit discharges. This effect was most pronounced at manholes upstream of a fully-submerged outfall, where the storm sewer pipes within the manhole were also fully-submerged. In these cases, any floatable debris traveling along the top of the storm sewer pipe will enter the manhole, and will remain suspended in the manhole pool, as they are not able to escape through the submerged outlet pipe. In these cases, the submerged manhole acts as a trap for much of the floatable debris. While some may not consider gross solids a true illicit discharge, it does meet the definition of an illicit discharge, since it is a substance present in the discharge that is not comprised entirely of stormwater. In most cases, there will be one or more access points which allow the debris to enter the MS4. Because of this, the presence of significant floatable debris in upstream manholes caused the illicit discharge potential of the outfall to be raised to “potential.” Upstream manholes with isolated solid waste or debris (generally three or fewer pieces) are not included in this list, and were not considered potential illicit discharges. These manholes were rescreened in June 2012, along with the upstream manholes for the outfalls in the 2012 ongoing screening program. A list of manholes with debris was provided to the City so the debris could be removed prior to conducting the ongoing screening in September. If additional debris did not accumulate prior to the ongoing screening, the illicit discharge potential of the outfall was considered “unlikely.” If the debris was still present or additional debris had accumulated, the outfall was classified as “potential.” March 25, 2013 27 2012 Ongoing Screening Summary Report City of Oshkosh Upstream manholes that were classified as “potential” sources of illicit discharge due to significant floatable debris in 2011 are shown in Table 5. The June 2012 prescreening results are also shown, along with the September ongoing screening results (if applicable). Of the 11 manholes that were rescreened due to floatable debris in 2011, 4 manholes still had sufficient debris to be classified as “potential” illicit discharges. In some cases, it appears that the manholes were not cleaned. In other cases, the manholes appeared to accumulate new debris. In addition to the four manholes that continued to be classified as “potential” sources from 2011, one manhole was identified from the 2012 ongoing screening district. That manhole is also listed in Table 5, along with the photos from the 2012 prescreening and ongoing screening. Note that in some cases, sediment and/or vegetation falls into the manhole when the manhole cover is removed, and those materials also appear in the photos. The severity of the floatable debris is based on the presence of the original debris and solid waste.

These manholes should be cleaned several months prior to the next outfall screening. By doing this, it will be possible to determine if the debris is from a prior discharge, or if the problem is ongoing. If it is determined that it is an ongoing problem, upstream inlets, especially those located near dumpsters or other solid waste storage areas, should be closely examined in an attempt to locate the source of the discharge. These areas could then be targeted for public education campaigns. A map showing the locations of the manholes with floatable debris is included in Appendix D. Outfall 02-322 (Rahr Avenue Manhole) Outfall 02-322 consists of a 15-inch vitrified clay pipe that discharges into Lake Winnebago at the end of Rahr Avenue. During the 2011 ongoing screening inspection (October 3, 2011), the outfall was fully submerged and could not be located. As a result, the screening was conducted at the first upstream manhole, located at the end of Rahr Avenue. Figure 14 - Upstream manhole 02-322 US1 (2011) The upstream manhole was partially submerged, with an 8-inch deep pool at the bottom of the manhole. A sample was collected from the pool, and the pH of the sample was 5.21, which is below typical range for pH in stormwater samples. March 25, 2013 32 2012 Ongoing Screening Summary Report City of Oshkosh Figure 15 - Upstream manhole 02-322 US1 (2011) The next upstream manhole (02-322 US2) was inspected. There was no water present in the manhole, so the flow could not be tracked upstream. The upstream manhole (02-322 US1) was reinspected on October 4, 2011. The pH was measured at 5.24, which was similar to the first sample. Once again, there was no water present in the next upstream manhole. It was recommended that this outfall be cleaned and rescreened during the 2012 ongoing screening program to determine if the low pH was an isolated incident or an ongoing discharge. The outfall and upstream manhole was rescreened as part of the gross solids pre-screening on June 20, 2012. The upstream manhole still had significant debris and sediment, and had a strong sewer odor. The sample from the manhole pool had an ammonia concentration greater than 6 ppm (the upper limit of the test strips). Figure 16 - Upstream manhole 02-322 US1 (6/20/2012) The Illicit Discharge Coordinator was informed of the condition of this manhole on June 26, 2012, along with a recommendation to vacuum this segment of storm sewer. It was also recommended that the manhole be rescreened later in the year, after it was cleaned out. March 25, 2013 33 2012 Ongoing Screening Summary Report City of Oshkosh The manhole was rescreened on September 27, 2012. It appeared that the amount of gross solids in the manhole had been reduced, although there was still a moderate amount of debris present. The sewer odor was still easily detected, and the sample from the manhole pool had an ammonia concentration of 3 ppm. Figure 17 - Upstream manhole 02-322 US1 (9/27/2012) The next upstream manhole (02-321) was inspected, and similar to 2011, it was dry, although it had significant sediment. Figure 18 - Upstream manhole 02-321 (9/27/2012) Based on this observation, it appears that the ammonia is entering the storm sewer between manholes 02-321 and 02-322. A sanitary sewer manhole was observed in Rahr Avenue between the two manholes. The flowline of the manhole had a small crack, and some of the flow appeared to be escaping through this crack. This could be a potential source of the ammonia in storm manhole 02-322. The Illicit Discharge Coordinator was informed of the findings of the investigation on October 1, 2012. The report suggested that the upstream manholes be cleaned out, and that the crack in the sanitary sewer manhole be investigated to determine if it is leaking into the storm sewer. It March 25, 2013 34 2012 Ongoing Screening Summary Report City of Oshkosh is recommended that this manhole continue to be screened until the source of the ammonia and sewer odor is identified and eliminated. Additional maps and information related to this investigation are included in Appendix D. Outfall 06-2241 (Knapp Street) Outfall 06-2241 is a concrete box culvert under N. Knapp Street that discharges to Campbell Creek from the south. It is located immediately west of the wastewater treatment plant and city garage. It was installed in 2011, and replaces former outfalls 06-15 and 06-560. Figure 19 - Outfall 06-2241 (6/13/2012) The outfall was initially screened on June 13, 2012 as part of the gross solids pre-screening. At that time, the outfall was partially submerged, and a sample was collected from the first upstream manhole. This sample had a faint sewage odor, and had an ammonia concentration of 3 ppm. The manhole was resampled on June 20, and had an ammonia concentration of 0.5 ppm and no odor. A sample was also collected from the receiving water, upstream of the outfall, and this stream sample also had an ammonia concentration of 0.5 ppm. It was noted that the receiving water had algae and other decaying vegetation, which could cause elevated ammonia concentrations in the submerged pool. The outfall was rescreened on September 27. The receiving water was clear, and the upstream manhole sample had no ammonia or odor. The elevated ammonia is likely the result of decaying vegetation in the receiving water, which is backing up into the upstream manhole. However, due to the proximity to the wastewater treatment plant and other industrial properties, it is recommended that this outfall be rescreened in 2013 to determine if elevated ammonia levels are present. Additional maps and information related to this investigation are included in Appendix D. Outfall 13-1716 (Victory Car Wash) “Outfall” 13-1716 consists of an 18-inch PVC pipe on the south side of the detention basin on Capital Drive. The pipe is located immediately east of outfall 13-1715, and was assumed to be another pond inlet (supplemental outfall) during the field screening on June 12, 2012. Upon further review, it was discovered that this pipe is actually the pond outlet, and the adjacent manhole that was screened was the first downstream manhole. March 25, 2013 35 2012 Ongoing Screening Summary Report City of Oshkosh Figure 20 - Outfall 13-1715 (right) and pond outlet 13-1716 (left) Because the pipe was partially submerged, the manhole was screened. Upon opening the manhole, a black pool was observed along the flowline, and a petroleum odor was noted. A sample collected from the pool had an ammonia concentration of 3 ppm and a detergent concentration of 1.3 mg/L. The Illicit Discharge Coordinator was notified of the discovery on June 12. Figure 21 - Manhole 13-1716 US1 (6/12/2012) OMNNI met with the Illicit Discharge Coordinator on June 13 to investigate the discharge. It appeared that the PVC pipe discharging to the manhole was coming from the trench drain at the exit of the Victory Car Wash, immediately east of the pond. A sample was collected from the water in the trench drain, but there was too much turbidity interference to get a good reading. Another sample was collected from the manhole pool, which had a detergent concentration of 1.3 mg/L. A sample collected from the pond had a detergent concentration of 0.6 mg/L. March 25, 2013 36 2012 Ongoing Screening Summary Report City of Oshkosh Figure 22 - Trench drain at Victory Car Wash Based on the information collected during the June 13 investigation, it appeared that the detergent was likely coming from the trench drain at Victory Car Wash. The City planned to have the plumbing inspector investigate the trench drain connection. Because parts of the parking lot drain to this location, it may not be possible to connect this drain to the sanitary sewer due to infiltration/inflow issues. It is recommended that this outfall be added to the 2013 ongoing screening program to determine if the detergent discharge is still occurring. If it is determined that the trench drain is connected to the storm sewer, the outfall should continue to be monitored after the trench drain is disconnected to verify that the drain was indeed the source of the detergent. Additional maps and information related to this investigation are included in Appendix D. Outfall 16-1508 (N. Westfield Street) Outfall 16-1508 consists of a 54-inch reinforced concrete pipe that discharges to Sawyer Creek from the south. The outfall is located approximately 60 feet east of the Westfield Street bridge. The outfall was previously named 16-487 before it was reconstructed in 2011. Figure 23 - Outfall 16-1508 (5/30/2012) The outfall was initially screened on May 30, 2012 as part of the gross solids prescreening. Because the outfall was partially submerged, the upstream manhole was screened. A sample March 25, 2013 37 2012 Ongoing Screening Summary Report City of Oshkosh was collected from the submerged pool in the manhole, and the sample had an ammonia concentration of 1 ppm. The Illicit Discharge Coordinator was informed of the detection on May 30, 2012. The manhole was resampled on June 6, 2012. The sample collected on this date did not have ammonia. No additional investigation was conducted for this outfall at that time, but it was decided that the outfall should be checked one more time before the end of the year. The outfall was rescreened on September 27, 2012. At that time, the Sawyer Creek stream channel was under construction. The outfall was still partially submerged, and a sample was collected from the upstream manhole. Figure 24 - Outfall 16-1508 (9/27/2012) The sample collected from the upstream manhole had an ammonia concentration of 3 ppm, which was higher than the May 30 sample, and warranted tracing of the source. The various manholes upstream of the outfall were sampled in an attempt to isolate the segment of the storm sewer where the ammonia was being introduced. After collecting samples from the various upstream manholes, it was determined that the ammonia concentration was 3 ppm at manholes 16-1508 and 16-1504. However, at the next upstream manhole (16-430), no ammonia was detected. It appeared that the ammonia was being introduced between manholes 16-460 and 16-1504. The land use in this area consists of multifamily residential property on the west side of Westfield Street, and Red Arrow Park on the east side of the street. A building housing the restrooms for the park is located immediately to the east of this segment. Based on the elevated ammonia levels in the segment adjacent to the park restroom building, this was identified as a potential source. Additionally, Red Arrow Park is a former landfill site, and infiltration of groundwater from the site could be another potential source. March 25, 2013 38 2012 Ongoing Screening Summary Report City of Oshkosh Figure 25 - Park restroom building upstream of 16-1504 The Illicit Discharge Coordinator was notified of the findings on September 28. At that time, OMNNI recommended that the storm sewer segment between manholes 16-460 and 16-1504 be televised to inspect for potential leaks or cross connections, particularly in the area of the restroom building. It is recommended that this outfall and upstream manhole continue to be rescreened until the source of the ammonia is identified. After the source is identified and remedied, an additional screening should be conducted to verify that the ammonia is no longer present in the discharge. Additional maps and information related to this investigation are included in Appendix D. INVESTIGATIONS DUE TO ILLICIT DISCHARGE REPORTS In addition to the routine outfall screenings that were conducted as part of the 2012 ongoing screening program, OMNNI also investigated three potential illicit discharges at the City’s request. These investigations were prompted by reports of unusual conditions near the City’s outfalls or within the storm sewer system. These three investigations are not included in the statistics in this report, but the descriptions of the investigations have been included for general reference. Outfall 14-582 (W. 28th Avenue) Outfall 14-582 consists of a 27-inch reinforced concrete pipe that discharges to the stream at the east end of W. 28th Avenue. The outfall was investigated in 2011 due to an illicit discharge of ammonia and chlorine from the Hydrite Chemical facility at the west end of W. 28th Avenue. The cross-connection was identified and remedied, and subsequent inspections showed no discharge from the facility. (Additional information is available in the City of Oshkosh 2011 Ongoing Screening Summary Report (March 6, 2012). As recommended in the 2011 Summary Report, the outfall was rescreened as part of the 2012 ongoing screening program. The outfall was screened on June 20, 2012. No abnormal physical or chemical indicators were observed at the outfall. The upstream manhole near Hydrite Chemical was also screened. The manhole was wet at the time of the inspection, but there was no flow observed. Based on the observations, it appeared that the illicit discharge from 2011 had been resolved. March 25, 2013 39 2012 Ongoing Screening Summary Report City of Oshkosh Figure 26 - Outfall 14-582 (6/20/2012) Figure 27 - Manhole 14-582 US1 (6/20/2012) The City contacted OMNNI on September 5, 2012 with a request to investigate a report of a black discharge into the stream near the outfall pipe. OMNNI investigated the outfall on September 5. Upon arriving, a black pool was observed in the stream around the outfall pipe, and a strong odor was present in the surrounding area. The odor was similar to the odor associated with anaerobic decomposition. March 25, 2013 40 2012 Ongoing Screening Summary Report City of Oshkosh Figure 28 - Black discharge at outfall 14-582 (9/5/2012) The upstream manholes along W. 28th Avenue were inspected. Evidence of the discharge was not observed in any of the upstream manholes. No apparent discharge to the storm sewer was identified. The upstream and downstream extents of the plume were located. The plume appeared to extend approximately 280 feet upstream from the outfall, and 350 feet downstream from the outfall. While identifying the extents of the plume, the shoreline was searched for potential unidentified outfalls. No additional outfalls were located. The samples collected from the stream did not contain any abnormal chemical indicators to help identify the substance in the stream, other than a low pH. A sanitary sewer line and lift station was observed in the area around the outfall, so OMNNI recommended that the City investigate if there were any leaks in the sanitary sewer or lift station. Another potential source would be an illegal dumping of material from the bridge. OMNNI notified the City of the inspection results in an email on September 5. The outfall was re-screened on September 27. At that time, there was no trace of the black discharge in the stream. Based on this discharge and the history of illicit discharges at this outfall, it is recommended that this outfall be rescreened during the 2013 ongoing screening program. Additional information and maps related to this investigation are included in Appendix E. Outfall 02-184 (Legion Place) The City contacted OMNNI on December 4, 2012 with a request to investigate a report of suds in Lake Winnebago near outfall 02-184. The City had received a complaint about suds along the shoreline from a resident on Legion Place on November 9, 2012. The resident had stated that the suds were common during the summer of 2011, and that they were again present. The City investigated the report, but no suds were observed during the investigation. The caller was advised to notify the City if the suds reappeared. The resident contacted the City on November 30 to report that the suds were present again at that time. OMNNI investigated the area around the outfall on December 6. Outfall 02-184 consists of an 8- inch clay pipe that is fully submerged and could not be located. The first upstream manhole (02- 184) is located directly west of the outfall on Legion Place, and has two short segments to the March 25, 2013 41 2012 Ongoing Screening Summary Report City of Oshkosh north and south of the manhole. The actual drainage basin only consists of five residential parcels along the shoreline. A separate storm sewer pipe runs parallel to this branch in Legion Place, and discharges at outfall 02-357, north of outfall 02-184. OMNNI met with the resident that reported the suds to the City. Some suds were present on the shoreline near the outfall. Samples of the suds and lake water were collected near the outfall and at two locations along the shoreline north of the outfall. Because the outfall was submerged, a sample was also collected from the pool in the upstream manhole. Figure 29 - Suds along shoreline north of outfall 02-184 Figure 30 - Pool in upstream manhole 02-184 US1 The suds observed on December 6 were consistent with the appearance of the suds that can be formed by natural surfactants in surface water. However, the sample that was collected from the pool in the upstream manhole had a detergent concentration of 0.2 mg/L, and an ammonia concentration of 3-6 ppm. These chemical indicators suggest that sanitary sewage may be present in the storm sewer, which could be causing the suds in the lake. March 25, 2013 42 2012 Ongoing Screening Summary Report City of Oshkosh Figure 31 - Ammonia test from upstream manhole 02-184 US1 Figure 32 - Detergent test from upstream manhole 02-184 US1 Based on the sample results, OMNNI recommended that the City televise the entire storm sewer branch to locate any potential sanitary cross connections. An email was sent to the Illicit Discharge Coordinator on December 6 summarizing the results and the recommended action. After the storm sewer was televised, it appeared that the storm sewer outfall had been abandoned. The City will conduct additional follow-up to check for connections. It is recommended that this outfall be screened again in 2013 to determine if the discharge of ammonia and detergent is ongoing. Additional information and maps related to this investigation are included in Appendix E. Outfall 13-1758 (Washburn Street) The City contacted OMNNI on December 11, 2012 to report that city crews had encountered oil in a storm sewer manhole while surveying the area around Washburn Street just south of STH 44, and requested that OMNNI assist with identifying the source of the oil. OMNNI conducted an investigation on December 12 to identify the source of the oil and define the downstream extent of the contamination. March 25, 2013 43 2012 Ongoing Screening Summary Report City of Oshkosh Figure 33 - Oil on survey rod from storm manhole 13-1743 (12/11/2012) With assistance from two city survey staff, the storm sewer branch for outfall 13-1758 was investigated. Outfall 13-1758 is a reinforced concrete pipe that discharges to the USH 41 southbound right-of-way, south of STH 44. The pipe was partially submerged, and an oil sheen was present in the pool at the end of the pipe. After discharging from the outfall, the flow followed a swale in the USH 41 right-of-way, and crossed under STH 44 through another concrete pipe. This pipe discharged to the USH 41 right-of-way north of STH 44. There is a small pool at the discharge of this culvert pipe, which also contained an oil sheen. The pool stopped a short distance north of the pipe, and no additional flow or sheen was observed. Figure 34 - Pool at end of outfall 13-1748 (12/12/2012) March 25, 2013 44 2012 Ongoing Screening Summary Report City of Oshkosh Figure 35 - Downstream extent of oil sheen Various branches of the storm sewer system upstream of outfall 13-1748 were investigated to determine the extent of the oil, and to identify potential sources. Oil was present in the detention basin on the east side of Washburn Street, and the heaviest concentration of oil seemed to be in manhole 13-1743, which received flow from the swale on the west side of Washburn Street. Figure 36 - Drainage swale pipe connection to manhole 13-1743 A sample was collected from manhole 13-1743. No chemical tests were conducted on this sample, as it was obviously a petroleum product. Based on the odor, it appeared to be diesel fuel or a heavier oil. March 25, 2013 45 2012 Ongoing Screening Summary Report City of Oshkosh Figure 37 - Sample collected from manhole 13-1743 After investigating the area around the drainage swale, a 4-inch PVC pipe was located coming from Quent’s service center. When the pipe was exposed, water and petroleum discharged to the drainage swale. The appearance and odor from the discharge was consistent with the oil that was observed in the downstream manholes. The Illicit Discharge Coordinator was called at approximately 12:00 pm and notified of the discovery. OMNNI marked the pipe location and left the site. The Illicit Discharge Coordinator visited the site during the afternoon and had the Hazardous Materials Response Team deploy oil containment booms in the area. The pipe was identified as the sump pump discharge from Quent’s Service Center. The Fire Chief investigated the inside of the building on December 12, and observed oil on the surface of the sump pit. The City reported the discharge to the WDNR spills hotline. The WDNR sent a letter to the owner of Quent’s Service Center on December 27 informing them of the reported contamination and their responsibility to restore the site. From this point forward, the WDNR will be leading the investigation. It is recommended that this outfall be rescreened during the 2013 ongoing screening program to monitor the progress of the cleanup and check for any additional discharges. Additional information and maps related to this investigation are included in Appendix E. OUTFALL CONDITION ASSESSMENTS While not required for the illicit discharge field screening, OMNNI inspectors noted the presence of any structural damage, significant deposition or erosion, or graffiti at the outfalls. This information can be passed along to the appropriate personnel for any necessary action. Damage Eighteen outfalls showed signs of damage that may require attention in the near future. Common types of damage included corroded metal pipes and aprons, displaced concrete apron sections, and damaged concrete pipes and abutments. The outfall damage that was observed during the ongoing screening program is summarized in Table 6.

As deposition increases, flow may become restricted in the pipe or downstream channel. Outfalls with moderate or severe deposition may need to undergo maintenance to remove the deposited sediment and debris and maintain proper flow. The outfall deposition that was observed during the ongoing screening program is summarized in Table 7.

Most of the outfalls with minor erosion could be repaired with minor landscaping repairs. Those outfalls March 25, 2013 54 2012 Ongoing Screening Summary Report City of Oshkosh with moderate or severe erosion may need additional structural reinforcement, such as turf reinforcement mat or riprap. The erosion that was observed during the ongoing screening program is summarized in Table 8.

The graffiti was relatively minor, but should probably be monitored to make sure that it does not become more severe. March 25, 2013 55 2012 Ongoing Screening Summary Report City of Oshkosh The graffiti that was observed during the ongoing screening program is summarized in Table 9.

A total of 97 outfalls were screened, along with upstream monitoring locations when necessary. Sixteen of those outfalls were included due to potential illicit discharges identified in the 2011 screening program. Of those 97 outfalls, 88 exhibited March 25, 2013 56 2012 Ongoing Screening Summary Report City of Oshkosh unlikely potential of past illicit discharges and 9 were classified as “potential.” These results are summarized in Figure 82: Figure 82 - Illicit discharge potential Those outfalls classified as “potential” or “obvious” should be given special attention in the ongoing screening program. In addition, OMNNI investigated three potential illicit discharge incidents at the request of the City. In all three cases, evidence of potential illicit discharges was documented. The ongoing screening also identified 18 outfalls with structural damage, 19 with deposition, 4 with noticeable erosion, and 3 with graffiti. While none of these posed an immediate danger, the City will likely want to address these issues as part of the regular storm sewer system maintenance. The ongoing screening program will continue in 2013 with the inspection of approximately 85 outfalls, plus the 9 outfalls from the 2012 program that were recommended for rescreening. At the conclusion of the 2013 ongoing screening, all identified major, minor and supplemental outfalls in the City will have been inspected at least once. Future outfall screenings may continue the existing four-year cycle, or be modified with a revision and subsequent WDNR approval of the Ongoing Screening Program. STANDARD OF CARE The conclusions presented in this report were arrived at using generally accepted engineering practices. The conclusions presented herein represent our professional opinions, based on data collected at the time of the inspections, at the specific inspection locations discussed in this report. Conditions at other locations in the City or at different times may be different than March 25, 2013 57 2012 Ongoing Screening Summary Report City of Oshkosh described in this report.

Most of the issues involved gross solids in the manholes. The first page of the attached list shows the outfalls that were re-screened due to the presence of chemical indicator parameters in the samples. In most cases, the samples collected at these outfalls during the re-screen came back clean. However, two outfalls – 02-322 and 16-487 (16-1508 after reconstruction) had ammonia detections. Maps and summaries of these two outfalls were sent to you via separate emails. Suggested actions, including 2013 follow-up screening, are listed in bold. 12 manholes were re-screened due to gross solids. Based on your correspondence, it sounded like these manholes were cleaned out this summer. In most cases, we noticed a significant reduction in the amount of gross solids in those manholes. Most still had some isolated debris, but not the heavy accumulation that was present in June. However, the amount of gross solids in four manholes did not appear to change since the June screening (highlighted in orange in the attached table): • 01-520 • 03-22 • 03-35 • 06-831 (06-829 US1) In most cases, it appeared that the gross solids in these manholes were the same solids that were observed in June. It is suspected that these manholes were not cleaned out, possibly due to accessibility issues with the vac truck. If this is the case, and if these manholes will not be cleaned out (via vacuum or by hand) in the future, it is probably not cost- effective to continue to inspect these manholes each year if nothing is going to change. However, if these manholes were cleaned out since June and once again have large amounts of gross solids, then a significant upstream source of solid waste must be present, and should be investigated to try to minimize future gross solids. If you have any questions about these results, please let us know. Jason Weis, P.E., CPESC GIS Manager / Municipal Project Manager OMNNI Associates, Inc.

When we inspected it on Thursday, it appeared that the manhole had been vacuumed out, but there was still quite a bit of vegetative debris (leaves) in the manhole, and the manhole had a strong odor of rotting organics (not necessarily a sanitary sewer odor). The ammonia concentration in the manhole was approximately 3 ppm. No other indicator chemicals (chlorine, detergent, etc.) were detected. We checked the next upstream manhole, located approximately 36 ft to the west. There was no flow in this manhole, but there was a significant amount of wet sediment in the manhole, which was blocking approximately half of the outgoing pipe. There was also a sanitary sewer manhole in the area, between the two storm manholes. The flow in this manhole was to the west. A crack was observed along the flowline of the manhole, and it appeared that some of the flow may be escaping through that crack. It is unknown if this crack is related to the increased ammonia levels in the storm sewer. It appears that the first upstream manhole (02-322) was probably cleaned out as a result of the spring pre-screening inspections, but the upstream manholes were not. Due to the accumulation of sediment and vegetation in the upstream manhole(s), the City may want to flush out the entire branch of the storm sewer on Rahr Ave, both to remove potential ammonia sources, and to improve the current flow capacity of the storm sewer. The City may also want to take a closer look at the crack in the sanitary sewer manhole, and determine if it is possible that the sanitary sewer could be leaking into the clay storm sewer. We’d be happy to take another ammonia sample after the storm sewer is more thoroughly cleaned out this year. Otherwise, we will simply add this outfall to next year’s screening program, and check it next spring. Jason Weis, P.E., CPESC GIS Manager / Municipal Project Manager OMNNI Associates, Inc.

In addition to the potential issue around Victory Car Wash, we found two more manholes with slightly elevated ammonia: 13-3427 (South Park) – 1 ppm ammonia – The storm sewer consists of two curb inlets that discharge to the pond through a submerged outfall. The sample was collected at the downstream inlet, which was partially submerged and had quite a bit of vegetation in it. Because the storm sewer system consists only of the two inlets, I would strongly suspect that the ammonia is from the decomposition of the organic material in the basin, and no additional tracking is needed. If you’d like, these inlets could be vacuumed out, and we can re-screen them later in the year. 06-15 / 06-560 (Knapp St) – 3 ppm ammonia - It appears that the two storm sewer lines are now combined into one box culvert. A sample was collected at manhole 06-709 (from the old storm sewer map). The sample (and manhole) had a slight “sewage” smell to it, but we originally figured it was due to the proximity to the WWTP. However, the ammonia concentration is higher than we would expect from decaying vegetation in the pooled water, especially water this clear. We can re-sample this outfall when we are back in Oshkosh early next week, to see if the ammonia is still present, and possibly check some other manholes to compare it. Because it appears that the storm sewer was reconstructed, do you have any mapping that shows the new configuration? Brian will run the detergent tests for all of the samples later this afternoon. If we get hits on anything (especially the Victory Car Wash trench grate), we’ll let you know. Jason Weis, P.E., CPESC GIS Manager / Municipal Project Manager OMNNI Associates, Inc.

It appears that this box culvert replaced the pipes associated with outfalls 06-15 and 06-560. The sample had a slight “sewage” smell to it, and had an ammonia concentration of 3 ppm, which is higher than we typically see from decaying organic materials in the pools. Because of the elevated ammonia concentration, the City may want to attempt to trace this discharge. The outfall is close to the wastewater treatment plant. However, since this appears to be a new storm sewer, a cross connection is not likely. In some of our other investigations, we’ve discovered that WWTP effluent standards for ammonia are often significantly higher than the illicit discharge action levels. Because the WWTP outfall discharges to the same receiving water, perhaps the overall ammonia concentration of the receiving water is elevated, and that is what we were seeing in the sample. On our next trip to the outfall, we could collect a sample of the receiving water near the WWTP outfall to see if the overall level is elevated, or if it appears to be coming from the storm sewer pipe. Because the storm sewer appears to be newly reconstructed, please send us a map showing the new layout. Also, since it has probably been a few years since we updated the storm sewer mapping in our GIS, please send the updated storm sewer shapefiles for the City at your convenience. A map is attached showing the general layout along with the inspection photos and results. We will collect another sample from this manhole (and the manhole that was later located closer to the actual outfall) to determine if the ammonia is still present next week.

Subject:RE: Ammonia detection - manhole 13-1716 Attachments:13-1716.pdf James: After checking the mapping, you are correct. Based on the mapping that I had with me in the field, it appeared that the two pipes entering the pond from the south were both inlets, since they were less than 10 feet away from each other and at roughly the same elevation. However, after seeing the mapping, I can see that 13-1715 is the inlet, and "13-1716" is the outlet. So, while we probably didn't need to screen 13-1716, we may have caught something in the process. The water is ponding in the manhole north of Capital Drive and in manhole (catchbasin) 13-1716, so there could be some type of obstruction downstream. Because no water is currently entering the outlet pipe from the pond (the water level is well below the pipe invert), I would start to suspect the other pipe that is entering the manhole north of Capital Drive (from the northeast). This pipe is capped with an orifice cut into it. At the time, I didn't think too much of it with the ammonia detection, but with the additional detergent detection, it becomes a little more suspicious, especially since it appears to come from the direction of the Victory Car Wash. (See attached map with photos.) It may be worth determining where this pipe is coming from, and finding out if there are any upstream sampling points. However, since it seems to come from private property, we will probably need the help of the City and/or plumbing inspector. Ben and I will be in Oshkosh Wednesday morning working on the other outfalls. If you would like to meet to investigate this outfall, please call me at 920-585-3061.

The manhole was screened because the outfall (pond inlet) was partially blocked by sediment and debris, causing water to pool in the pipe. The water that was pooled into the manhole was very dark (black) and stagnant – I think this is probably the reason for the ammonia detection. I checked the upstream manhole/catchbasin (at the end of Goodwill’s driveway), and the water was ponded slightly into that manhole as well. The map showed that the next upstream manhole was in a brushy area to the east of the driveway, but I couldn’t find it. The next mapped manhole was in the AAA driveway (W South Park Ave), but it appeared that the flow was flowing south toward the storm sewer in South Park Ave, away from manhole 13-1716, so I stopped tracking at this point. I would suspect that that the elevated ammonia is due to the decaying organic material in the pipe rather than any illicit discharge entering the system. However, you may want to consider cleaning out this branch of the storm sewer to eliminate the stagnation, and then we can re-sample the outfall and/or manhole later this summer, along with any other problematic manholes or outfalls that we identify during this prescreening process. If you have any questions or other ideas, please let me or Brian know. I should be back in Oshkosh on Wednesday continuing the 2012 screening.

The follow-up inspections consisted mainly of the manholes in which we had previously identified gross solids issues, and outfalls/manholes that had previous chemical indicator parameter detections. One of these was the outfall on N Westfield St, near Red Arrow Park (previously 16-487 before the recent reconstruction). The upstream manhole (16-1508) had an ammonia detection of 1 ppm during the spring pre-screening. A subsequent inspection showed no ammonia. During Thursday's inspection, the ammonia in this manhole was 3 ppm. Due to construction in the receiving stream and vegetation inside the grate of the outfall pipe, flow was restricted, and the sample was collected from the submerged pool in the upstream manhole. Because of the elevated ammonia and the previous history of ammonia, we attempted to trace the ammonia upstream. All upstream manholes (up to and including Taft Ave) were partially-submerged, with no free-flowing stormwater. Samples were collected from the pools in several manholes/curb inlets upstream of the outfall. Based on the samples, it appears that the source of the discharge may be between manhole/inlet 16-1504 and 16-430. The ammonia at inlet 16-1504 was approximately 3 ppm, but no ammonia was detected at the next upstream inlet (16-430). It was noted that the restroom facility for Red Arrow Park was located in this stretch of storm sewer, which could be a potential ammonia source. It should be noted that, since the manholes were partially submerged and the samples were collected from submerged pools, the isolation of the suspect segment is not as precise as in a free-flowing storm sewer, since it is possible for the ammonia to disperse in the pooled stormwater. However, based on the sample results, this would probably be the first segment that should be investigated. The City may want to televise this segment of storm sewer to determine if there are any cross connections or other sources of ammonia infiltration. If you would like us to conduct any additional testing in the area, please let us know. I will send you a summary of the gross solids follow-up early next week. Many of the manholes had significantly less gross solids compared to the previous inspection. However, a few appeared to be similar, and may not have been cleaned. I should have the table updated on Monday or Tuesday. Jason Weis, P.E., CPESC GIS Manager / Municipal Project Manager OMNNI Associates, Inc.

The odor and color were reminiscent of discharging anaerobic sediment from the stormwater pump stations in Fond du Lac. However, there are no stormwater pump stations in this area. If any of the industrial/commercial properties in the area have pumps that could discharge anaerobic sediment, it may be worth checking them for a potential cross connection. The sanitary lift station at the end of the road could be another potential source, although the odor, color and chemical characteristics were more consistent with anaerobic sludge than sanitary sewer. However, it would probably be prudent to check the integrity of the incoming and outgoing sanitary sewer lines. Finally, it would probably be a good idea to check that Hydrite and the other industries on W. 28th Ave did not discharge any anaerobic or sulfur-containing wastewater down the storm sewer line this week. The upstream manholes make this seem rather unlikely, but it is still a possibility. I don't believe that the W. 28th Ave storm sewer was televised last year during the Hydrite investigation, but it might be worth televising this relatively short stretch due to the various complaints that it has been generating.

Jason Weis, P.E., CPESC GIS Manager / Municipal Project Manager OMNNI Associates, Inc. (920) 735-6900 (920) 830-6100 FAX jason.weis@omnni.com W. 28th Avenue (Outfall 14-582) Illicit Discharge Investigation James Rabe (City of Oshkosh) contacted Jason Weis (OMNNI Associates) at 9:58 am on September 5, 2012. Mr. Rabe had responded to a complaint of a potential illicit discharge at outfall 14-582. The outfall is located on W. 28th Avenue, just west of the railroad tracks, near the bridge. The property owner reported a strong odor around the outfall and a black discharge in the stream. Mr. Weis arrived at the outfall at 11:52. Mr. Rabe and the other City personnel had left the outfall. Upon arriving, a moderately strong sulfur odor was present around the bridge and outfall. The stream near the outfall was 40% covered with duckweed; other areas upstream and downstream were 80-90% covered. The stream exhibited ambiguous flow direction at the time due to wind and downstream wave action. In the areas with no duckweed, the water in the stream appeared to have a black tint. Figure 1 - Stream at outfall 14-582 The 27-inch RCP outfall pipe was examined for flow. The pipe was partially submerged, but no flow was observed coming from the pipe. A sample was collected from the stream immediately upstream (south) of the bridge. The sample exhibited a black tint, and had a strong sulfur odor. A field analysis of the sample showed no chlorine or ammonia. The pH of the sample was fairly acidic at 6.60. A later bench test showed no detergent was present. An attempt was made to locate the upstream extent of the black plume and odor. A sample was collected from the southwest corner of the parcel on the east side of the stream. No odor was detected at the stream bed, and the water in the stream appeared fairly clear. A sample was collected at this location. The sample had no odor and no tint. This sample was also field tested, and showed no chlorine or ammonia. The pH of this upstream sample was 7.62, which is fairly typical for stormwater. Using this sample as a control sample, it appeared that the black discharge had reduced the pH of the stream approximately 1.0 unit lower than the baseline. (The sample locations and upstream and downstream extents of contamination are shown on the attached map.) Figure 2 - Upstream location (control sample) The stream was followed downstream until the odor was detected and areas of black water were observed. The upper extent of the contamination was fairly sharp, and located approximately 275 feet upstream of the outfall. A sample was collected from this location, and a faint odor and black tint were observed. Figure 3 - Upstream extent of contamination Because of the ambiguous flow in this stream segment, the contamination did not appear to be migrating significantly during the investigation. Because the outfall pipe was partially submerged, upstream manholes on the storm sewer branch were screened to attempt to identify flow. The manhole immediately west of the intersection of W. 28th Ave and Bradley Street was the first upstream manhole that was located. When this manhole was screened, there was a trickle flow, with no evidence of black tint or staining. The sulfur odor was not apparent, and the sides of the manhole were dry, indicating that a large flow had not occurred in the recent past. Figure 4 - Upstream manhole at W. 28th Ave and Bradley St (east at top) During the investigation, the owner of the property immediately west of the outfall came to observe th e activities. He indicated that the odor and black tint appeared for the first time this morning, and that he had never seen this before in the seven years that he had been at this location. He confirmed that the odor and black tint were not present on Tuesday, September 4. An attempt was made to locate the downstream extent of the plume. Samples of the stream water were taken from the Fond du Lac Ave bridge and the railroad bridge. Neither sample had a black tint or sulfur odor, so the plume apparently did not migrate downstream to the railroad bridge. Figure 5 - Stream upstream of Fond du Lac Ave bridge Figure 6 - Stream upstream of railroad bridge The area between the W 28th Ave bridge and the railroad bridge is surrounded by fairly thick brush. The stream was approached from the east bank in several locations until the sulfur odor was barely detectable. Stream samples were collected from several locations to test for odor and tint. It appeared that the downstream extent was approximately 350 feet downstream of the outfall. The downstream extent was not as clearly defined as the upstream extent, partially due to the heavy cover of duckweed. Figure 7 - Downstream extent of contamination Outfall 14-582 is the only mapped outfall discharging within the observed contamination. No other outfalls were observed in this area during the investigation. Because of the fairly distinct upstream and downstream extents of the contamination plume, it is suspected that the source of the contamination is located in the immediate area. If the plume had migrated from an upstream source, the upstream edge would be expected to be less defined. Prior to starting the investigation, Mr. Weis had contacted Jan Brandenburg at the City’s wastewater treatment plant to inquire about the City ’s capabilities for E. coli testing, should the need arise. Mr. Brandenburg stated that he believed the contamination was likely due to a recent discharge of a dewatering pump near the Melvin Street pump station. However, after investigating the area, it was agreed that this pump station was too far away from the investigation area to be a potential source. A similar sulfur odor and black discharge is commonly encountered when conducting the IDDE outfall screening in other municipalities with stormwater pump stations. During the screening process for these outfalls, the pump stations are run several times to remove the accumulated stormwater from the sump and the upstream storm sewer(s), in an attempt to obtain fresh flow into the pump stations. Occasionally during this process, the pump stations are run to the point of discharging sediment and debris from the sump. This material is typically anaerobic, and the discharge of this material results in a strong sulfur odor and a black discharge, similar to the conditions observed on W. 28th Ave. However, no stormwater pump stations were observed in the area. Another potential source of anaerobic material is the streambed itself. If the streambed is significantly disturbed, deeper anaerobic layers can become suspended. If a significant flow was discharged from the outfall, a large scour hole would be expected at the end of the outfall pipe and under the bridge. However, when the sample was collected upstream of the W. 28th Ave bridge, the stream was approximately 12 inches deep, with no evidence of a scour hole. In addition, the upstream manhole showed no evidence of recent heavy discharge. A third potential source of contamination would be an illicit discharge from one of the neighboring properties in the drainage basin. The illicit discharge could be the discharge of anaerobic sump material, or it could be an anaerobic or sulfur-based wastewater discharge. This possibility could be best investigated by televising the storm sewer line on W. 28th Ave to check for potential cross connections. Also, if any private stormwater pump stations are observed at any of the properties, they could be considered potential sources. Finally, a sanitary sewer lift station was observed at the far east end of W. 28th Ave, approximately 280 feet east of the outfall. It appears that the sanitary sewer is located in the center of W. 28th Ave, and travels east to the lift station. To do this, it must cross the bridge near the outfall. While the discharge in the stream behaves more like anaerobic sludge than sanitary sewer (no ammonia present, different odor), it may be worth investigating the potential of a sanitary sewer leak coming into the lift station or in the force main downstream of the lift station. Figure 8 - Sanitary sewer lift station at end of W. 28th Ave It is recommended that the City continue to monitor this contamination plume and investigate potential sources of the contamination. Due to the lack of chemical indicators, it appears that the most effective method of tracking the contamination is by the presence of the sulfur odor and the black tint in the water. OMNNI would be happy to assist with any additional tracking or sampling that may be required. Upstream SampleUpstream Sample(No detection)(No detection)pH = 7.62pH = 7.62 Approx.

We are attempting to determine the potential source of the discharge into the creek at 28th Avenue that we met onsite to discussion. I had our Outfall Screening Consultant come out and take some samples for testing. They indicated that the smell reminded them of a storm sewer pump station wet well when it is pumped down for cleaning / inspection. The samples showed a lower than normal pH. The Plumbing Inspectors queried industries in the area to see if any had storm water pumping stations that may have been getting cleaned out. There were no affirmative responses. Therefore, our next step is to televise the storm sewer and sanitary sewer in the area to see if there are any potential sources we can identify. We would like to televise the storm sewer in 28th Avenue from the creek west to Oregon Street, then south to the terminus (just north of 29th Avenue). We would also like to televise the sanitary sewer in 28th Avenue from the pump station west to the terminus, in Bradley Street from 28th Avenue south to the creek, and in the easement west of the creek from 28th Avenue to the north.

Subject: 336 Legion Pl - Soap Suds Gentlemen, I received a phone call from retired Judge Bill Carver who lives at 336 Legion Pl. He stated that on and off he sees soap suds along the shoreline. He said it was quite common last summer, had showed up the day he originally called (11-9- 12:see attached photos), and he called again today to state that they showed up again yesterday. There is storm sewer that runs down Legion Pl, and discharges along his northern property line to Lake Winnebago. He did state that he had to do some re-routing of his sanitary discharge, and also connected some of his downspouts to the storm sewer. He is concerned that someone on this block still has their sanitary (maybe floor drain?) connected to the storm system. I am emailing you all to see if you had any ideas on the plan of attack for checking this. I am not sure where we are at with the I&I program with private properties to see if we would even be able to enter properties to verify their connections. Another problem we have is that the storm sewer itself is under lake level, and discharges underneath the shoreline riprap. Televising would prove to be difficult. Any guidance/suggestions/ideas would be appreciated. Thank you.

The wind was coming out of the south-southeast so the wave action seemed to inhibit any suds from accumulating. He collected samples at several locations (see attached map). The gentleman who reported the suds came out to talk to Ben. The attached photos show the areas around the sampling locations and some of the sample analysis. The ammonia, detergent, and higher conductivity (as compared to the lake water) detections at the upstream manhole 02-184 indicate the potential for an illicit discharge. (The sampling detections may or may not be related to the observed suds. There is still the potential that the suds were formed under natural conditions.) It might be helpful to televise the stormwater line between manholes 02-185 and 02-183 and from manhole 02-184 to the outfall. There was approximately eight inches of water in manhole 02-184; it was not fully submerged. If your televising equipment cannot be used in that depth of water, it might be worth checking the water levels in the pipes when the lake is drawn down. Otherwise you might consider dye testing. We will put this area on the monitoring list. Let me know if you have any questions on the attached information. Brian D. Wayner, P.E. Environmental Manager OMNNI Associates, Inc. One N.

Based on the amount of oil Jason observed, and the follow up information from the fire department, the released oil doesn’t appear to be a one-time small spill. The oil in the sump could be from: • Dumping oil directly into the sump • The sump picking up oil from a leaking above ground tank in the shop or a leaking underground storage tank • Trench drains that are connected to the sump Depending on how long this has been going on, the soils in the right-of-ways could be impacted. The WDNR typically requires an investigation of the spill if it cannot be cleaned up immediately. If it doesn’t look like the WDNR is requiring the extent of the release defined, you may want to follow up with them. If the City has to do work in the right-of-way in the future and contaminated soil is discovered, the soil needs to be properly handled/disposed. It might be easier to deal with the issue (if there is an issue) now, why the source is known. The WDNR GIS map shows a number of sites in the area with past environmental issues. Dealing with the issue now might avoid finger pointing in the future. If the WDNR is not requiring a soil impact investigation, but the city wants to understand if there is a problem, we can collect the soil samples. Let Jason or me know if you have any questions on the above items or the attachments. Brian D. Wayner, P.E. Environmental Manager OMNNI Associates, Inc. One N.

Washburn Street Oil Investigation December 12, 2012 Background On December 11, 2012, a survey crew for the City of Oshkosh was working along S. Washburn Street, south of STH 44. While surveying storm sewer manhole 13-1743 on the south side of Washburn Street, they encountered an oily substance in the manhole. The manhole had approximately 0.6 feet of water trapped in it, with the oily substance floating on the water surface. The oil coated the survey rod with an opaque black film (Figure 1). Figure 1 – Oil on survey rod from storm manhole 13-1743 The survey crew notified the City’s Illicit Discharge Coordinator (James Rabe) and continued to trace the discharge downstream toward MS4 outfall 13-1758, where the storm sewer discharges to the USH 41 right-of-way. All of the downstream manholes contained oil, as well as the pool at the end of the outfall. Mr. Rabe contacted OMNNI Associates, Inc. (OMNNI) on the afternoon of December 11 and requested that OMNNI assist with tracing of the discharge and possible identification of the source. OMNNI conducts the outfall inspections for the City’s Illicit Discharge Detection and Elimination (IDDE) program, has traced previous illicit discharges in the City. Investigation Jason Weis (OMNNI) met the two surveyors from the city at the site of the discharge at 8:00 am on December 12, 2012. The survey crew provided a brief history of their encounter, as well as the general layout of the storm sewer network in the area. 2 The drainage basin that discharges to this outfall is relatively small – less than 20 acres. It consists of storm sewer inlets in STH 44 that extend approximately 400 feet in both directions from Washburn Street, as well as the storm sewer inlets in Washburn Street for the first 1200 feet south of STH 44. The Washburn Street storm sewer also collects flow from a drainage swale south of Washburn Street, between Quent’s Service Center and the former Chief Equipment property on the south side of Washburn Street, and from a private detention basin located in front of the multi-tenant retail building located on the north side of Washburn Street. The investigation began by inspecting the various manholes in the storm sewer network to identify the extent of the oil contamination. An oil sheen and petroleum odor was observed at the pipe at the end of the drainage swale south of Quent’s Service Center. The flow was traced upstream through the drainage swale for approximately 20 feet, at which point no additional surface flow was observed. Figure 2 – Oil sheen at the end of the drainage swale A private storm sewer is located in the west parking lot of Quent’s Service Center. This storm sewer discharges to the drainage swale from the north. The outfall pipe was located, and was partially blocked by sediment and vegetation. A shallow pool of water was trapped at the end of the pipe. A sample was collected from this pool, and no sheen or odor was observed. Figure 3 – Private storm sewer outfall in swale 3 The upstream manholes in the private storm sewer were opened and inspected. Two manholes and one catchbasin were inspected, and were found to be either dry or have minimal pooling with no sheen. No odors or stains were observed in any of the private manholes or catchbasins south of Quent’s Service Center. The branch of storm sewer along STH 44 south of Washburn Street was inspected. Based on the survey crew’s activities on December 11, it was known that this branch entered manhole 13-1724 above the water level in the manhole. Manhole 13-2584 was inspected, and no sheen or stains were observed. A petroleum odor was present, but it was determined that this was likely venting from downstream manholes. Based on the observations in manhole 13-2584, it was determined that the discharge was not coming from this branch of the storm sewer. Figure 4 – Clean flow in manhole 13-2584 The branch on Washburn Street was investigated next. The manhole on the upstream end (13-1754) was inspected and found to be dry with no petroleum stains or odor. The next manhole (13-1749) was slightly submerged, and the flow appeared to be heading to the west (downstream). The flow entering from the east appeared to have a slight sheen, but did not have the dark, oily appearance that was observed at the end of the drainage swale. Figure 5 – No flow in manhole 13-1754 4 Figure 6 – Slight sheen in manhole 13-1749 The pond in front of the multi-tenant retail building on the north side of Washburn Street was inspected next. The building houses three tenants: 2nd Wind Exercise Equipment, Skiers Outlet and Golfers Outlet. The front parking lot for this building sheet flows into the detention pond. One PVC pipe was located on the north side of the pond, which appears to come from inside the building (i.e., roof drains). No catchbasins, inlets, or other private storm sewer were identified on the property. Figure 7 – Detention pond inlet pipe An oil sheen was observed on the surface of the detention pond. Near the inlet pipe, the sheen appeared to consist of clear oil droplets. Near the pond’s outlet pipe, near manhole/inlet 13-1743, the oil sheen was more opaque. The pond is likely designed to discharge to the storm sewer in Washburn Street. However, due to the partially-submerged condition at the outfall and the backed-up water in the storm sewer, the pond surface was at the same level as the storm sewer flow, and the water was free to flow between the storm sewer and the pond based on wind and other influences on flow. 5 Figure 8 – Detention pond outlet pipe The junction of the detention pond and drainage swale with the storm sewer is located at manhole/inlet 13-1743. This inlet was inspected, and the opaque oil sheen observed in the drainage ditch was also observed in this inlet. No obvious source of the oil was identified, but there appeared to be a slight flow to the west (downstream). Figure 9 – Detention pond outlet pipe connection to manhole 13-1743 Figure 10 – Drainage swale pipe connection to manhole 13-1743 6 A water sample was collected from this manhole. The water was ten inches deep, with an opaque film on the surface. The oily substance coated the sample pole and sample bottle. A strong petroleum odor was present. Figure 11 – Sample collected from manhole 13-1743 The remaining manholes between manhole 13-1743 and the outfall were inspected, and the oily substance was observed in each manhole. The inspection at manhole 13-1724 confirmed that the flow entering from the southwest branch did not contain oil. Figure 12 – Pipe from southwest branch entering manhole 13-1724 above the water level Outfall 13-1758 was located in the USH 41 right-of-way, south of the southbound on-ramp. The outfall pipe was approximately 90% submerged. The pool at the end of the outfall pipe had a brown-black opaque sheen with a strong petroleum odor, similar to the upstream manholes. 7 Figure 13 – Pool at end of outfall 13-1758 After leaving the outfall, the flow traveled northeast approximately 50 feet through a grass swale. A sheen was observed on this flow. The flow then entered a concrete culvert that traveled under STH 44 and discharged on the north side of STH 44. A dark sheen was observed on both the upstream and downstream ends of this culvert. Figure 14 – Sheen on pool in upstream end of STH 44 culvert Figure 15 – Sheen on pool in downstream end of STH 44 culvert 8 The stains on the downstream culvert apron showed that the oil level had once been 4 to 5 inches higher than the present level. After leaving the STH 44 culvert, the flow traveled north along the USH 41 off-ramp ditch. The flow was traced for approximately 45 feet past the end of the culvert, at which point no surface flow was visible. The survey crew placed a pair of lath at the estimated downstream extent of the flow. Figure 16 – Downstream extent of oil sheen Based on the observations in the upstream manholes, the most likely source for the oil appeared to be the drainage swale south of Quent’s Service Center. Starting at the downstream end of the swale, the surface flow was traced back up through the grass in the swale. Approximately 20 feet upstream from the end of the swale, the surface flow appeared to intensify from the north side of the swale. A metal fence post was located, which sometimes marks the location of a pipe. The area around the fence post was probed with a shovel, and a 4-inch PVC pipe was located. The pipe appeared to come from Quent’s Service Center. When the area around the end of the pipe was cleared with the shovel, the pipe appeared to discharge the oily substance, which quickly flooded the area and submerged the pipe. Based on the appearance of the discharge and the strong odor that was present with the new discharge, this 4-inch PVC was identified as a probable source. The location of the pipe was marked with a lath, and the Illicit Discharge Coordinator was informed of the discovery. 9 Figure 17 – 4-inch PVC pipe from Quent’s Service Center (submerged) OMNNI left the site at approximately 12:15 pm. Mr. Rabe investigated the site during the afternoon of December 12, 2012. Due to the severity of the contamination, he contacted the Fire Chief and asked to have the Hazardous Materials Response team deploy oil containment booms in the area. The Fire Chief spoke with the owner of Quent’s Service Center, who identified the PVC pipe as their sump pump discharge line. After investigating the inside of the building, oil was observed on the surface of the sump pit. The Fire Department will follow up with Quent’s Service Center on December 13.

This spill is more than a sheen on the water surface. There is free product on the water surface, indicating a more severe spill than originally thought. The City of Oshkosh Fire Department Hazardous Materials Response Team was dispatched to the site to install containment booms to help contain the spill and keep it from spreading. As we worked on that, we also further investigated the likely source. The source appears to be coming from a sump pump discharge pipe from Quent’s Service Station at 2167 STH 44. A pipe discharging to a drainage ditch was partially plugged by dirt and cattails. When the end of the pipe was exposed (below water elevation) a rush of water and petroleum came from the pipe. Fire Chief Franz and I further investigated with Quent’s Service Station. They checked their sump pump pit, and found oil present in the pit. The owner began working on clearing the oil from the surface. If you have additional questions, please do not hesitate to contact either myself, or Fire Chief Franz (copied on this email).
