E November 30, 2016 1 2016 Ongoing Screening Summary Report City of Oshkosh EXECUTIVE SUMMARY During the summer of 2016, OMNNI Associates, Inc. (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 revised in 2015, OMNNI inspected 98 of the approximately 425 MS4 outfalls identified in the City. The inspections consisted of a visual screening along with a chemical analysis of any dry-weather flow that was present. The inspections revealed 27 outfalls with evidence of potential or obvious illicit discharges, primarily manholes with trapped floating litter. BACKGROUND Purpose Under Section 2.3.2 of the Wisconsin Pollutant Discharge Elimination System (WPDES) Permit No WI-S050075-2 (“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. Each outfall is 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 municipal separate storm sewer system that receives storm water runoff from lands zoned for industrial activity that is associated with a drainage area of more than 2 acres or from other lands 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 WDNR to develop a third class of outfalls – “supplemental” outfalls. Supplemental outfalls are storm sewer outfalls which may not meet the legal 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. November 30, 2016 2 2016 Ongoing Screening Summary Report City of Oshkosh 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. The current MS4 map for the City of Oshkosh consists of 425 outfalls, including: 95 major outfalls 237 minor outfalls 93 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. Program History The activities that have taken place with the Illicit Discharge Program for the City of Oshkosh are summarized below: September 2009 – Initial Screening (major outfalls) 109 major outfalls screened, with 23 potential and one obvious illicit discharge identified. City of Oshkosh Initial Field Screening Summary Report (May 18, 2010) December 2009 – Ongoing Field Screening Program 348 MS4 outfalls identified, screened over a four-year inspection cycle. City of Oshkosh IDDE Ongoing Field Screening Program (May 19, 2010) August 2010 – 2010 Ongoing Screening 93 outfalls screened, with 26 potential illicit discharges identified. City of Oshkosh Ongoing Screening Summary Report – 2010 Inspection Year (March 28, 2011) June 2, 2011 – USEPA Audit Assisted with questions concerning the IDDE program October 2011 – 2011 Ongoing Screening 121 outfalls screened, with 15 potential and one obvious illicit discharge identified. City of Oshkosh Ongoing Screening Summary Report – 2011 Inspection Year (March 6, 2012) October 2012 – 2012 Ongoing Screening 100 outfalls screened, with 12 potential illicit discharges identified. City of Oshkosh Ongoing Screening Summary Report – 2012 Inspection Year (March 25, 2013) July 2013 – 2013 Ongoing Screening 95 outfalls screened, with 7 potential illicit discharges identified. City of Oshkosh Ongoing Screening Summary Report – 2013 Inspection Year (February 20, 2014) October 2014 – 2014 Ongoing Screening 42 outfalls screened (prior potential illicit discharges), with 17 potential illicit discharges identified. City of Oshkosh Ongoing Screening Summary Report – 2014 Inspection Year (February 23, 2015) September 2015 – Ongoing Field Screening Program Revision (draft) 425 MS4 outfalls identified, with 60 priority outfalls. City of Oshkosh IDDE Ongoing Field Screening Program – 2015 Revision (September 16, 2015) November 30, 2016 3 2016 Ongoing Screening Summary Report City of Oshkosh September 2015 – 2015 Ongoing Screening 98 outfalls screened, with 20 potential and one obvious illicit discharge identified. City of Oshkosh Ongoing Screening Summary Report – 2015 Inspection Year (January 8, 2016) October 2016 – 2016 Ongoing Screening 98 outfalls screened, with 27 potential illicit discharges identified. City of Oshkosh Ongoing Screening Summary Report – 2016 Inspection Year (November 30, 2016) The 2015 revision to the Ongoing Screening Program implemented the “priority outfall” concept that was introduced by the WDNR in a March 2012 guidance document. These priority outfalls are outfalls that have the highest likelihood of a potential illicit discharge based on the characteristics of the drainage basins for each outfall. The priority outfalls are scheduled to be screened annually, while the non-priority outfalls are screened less frequently (every five years for major outfalls, every ten years for non-major outfalls). The current version of the program includes 46 priority outfalls. The 2016 outfall screening followed the 2015 revision to the Ongoing Screening Program. The priority outfalls were screened, along with a subset of the non-priority outfalls. Based on the field observations during the screening, the Ongoing Screening Program may be modified slightly for future years. The outfalls that were included in the 2016 screening program are shown in Appendix A, and the associated outfall inspection reports are included in Appendix B. The City may need to include these results in the annual report required by the MS4 permit due March 31, 2017. 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 and discussions with the WDNR. 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 48 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 48 hours, November 30, 2016 4 2016 Ongoing Screening Summary Report City of Oshkosh 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: pH Chlorine (total chlorine and free chlorine) Detergents Ammonia Temperature Conductivity 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 receiving 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. While not expressly 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 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. November 30, 2016 5 2016 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 northeast of the intersection of Bowen Street and Nicolet Avenue in the City of Oshkosh. The conditions at this weather station were considered representative of the weather in the City of Oshkosh for the 2016 ongoing screening. The location of the weather station is shown in Figure 1. Figure 1 – Location of weather station for weather history November 30, 2016 6 2016 Ongoing Screening Summary Report City of Oshkosh The weather history from September 10, 2016 (one month prior to the start of inspections) through October 26, 2016 (one week after the completion of inspections) from this weather station is shown in Figure 2. Figure 2 – Summer 2016 weather history (Weather Underground) November 30, 2016 7 2016 Ongoing Screening Summary Report City of Oshkosh Outfall inspections were conducted in the City of Oshkosh on October 10, 18 and 19, 2016. Those inspection dates (red), along with the daily rainfall history (blue), are shown in Figure 3. Figure 3 – Rainfall history and outfall inspections Flow To meet the requirement of dry weather screening, outfalls were typically screened at least 48 hours after the previous runoff-producing rainfall event. Because the outfalls that were screened in 2016 were primarily submerged outfalls, flow could only be assessed at 11 of the outfalls. Submerged outfalls, along with the observed flow patterns, are described in the next section. November 30, 2016 8 2016 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. November 30, 2016 9 2016 Ongoing Screening Summary Report City of Oshkosh Submerged Outfalls Most of the outfalls in the City were located at or below the normal levels of their respective receiving waters. Of the 98 inspected outfalls, 25 were partially submerged, and 64 were fully submerged (Figure 5). Of the 64 fully submerged outfalls, 56 could not be physically located. Figure 5 – Submerged status of outfalls 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. Sampling locations are noted on the individual outfall inspection reports. 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 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 discharge. Other November 30, 2016 10 2016 Ongoing Screening Summary Report City of Oshkosh 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 even 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 severe November 30, 2016 11 2016 Ongoing Screening Summary Report City of Oshkosh 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 particularly 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 the age of the structure. These stains are typically found at either the normal or the high flowline for the pipe. November 30, 2016 12 2016 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 November 30, 2016 13 2016 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, or occur in conjunction with other indicators. In 2016, 26 outfalls were classified as potential illicit discharge because of the presence of moderate or severe gross solids in their upstream manholes. These outfalls are discussed in more detail in the Potential Illicit Discharges section of this report. No other outfalls were classified as potential illicit discharge solely due to physical indicators. November 30, 2016 14 2016 Ongoing Screening Summary Report City of Oshkosh 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, based on the 2015 revision to the ongoing screening program: pH Temperature Conductivity Chlorine (total and free) Ammonia Detergents 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, or from the outfall pool if an upstream location was not available. A total of 86 stormwater samples were collected and analyzed as part of the ongoing screening process in 2016 – 13 were from flow streams, and 73 were from pools. 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. 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 a Hach Pocket Pro+ Multi 2 Tester 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 November 30, 2016 15 2016 Ongoing Screening Summary Report City of Oshkosh 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 6.65 to 9.45. One sample (12-1328a) was outside of the 6.0-9.0 normal range. Because the sample also had elevated pH in 2015, the outfall was classified as a potential illicit discharge, and is discussed in more detail in the Potential Illicit Discharges section of this report. 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 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 °F or warmer in summer. As a result, the “normal” temperature range was set at 55 °F to 90 °F. Any samples outside of this range could contain flow other than stormwater runoff. November 30, 2016 16 2016 Ongoing Screening Summary Report City of Oshkosh Testing Method During the ongoing screening program, OMNNI recorded the temperature of the outfall samples with a Hach Pocket Pro+ Multi 2 Tester handheld pH/conductivity/temperature meter, which displays the temperature reading to 0.1 °F. 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 71 °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, 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 November 30, 2016 17 2016 Ongoing Screening Summary Report City of Oshkosh 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 would be considered to be normal. Samples with conductivities over 2000 µS/cm would be identified as suspicious, but the discharge would not be considered a potential illicit discharge unless other indicator parameters (physical or chemical) were observed. Testing Method During the ongoing screening program, OMNNI recorded the conductivity of the outfall samples with a Hach Pocket Pro+ Multi 2 Tester 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. Figure 9 – Conductivity sample results 1 USEPA: Water-Monitoring & Assessment – Conductivity (http://water.epa.gov/type/rsl/monitoring/vms59.cfm) November 30, 2016 18 2016 Ongoing Screening Summary Report City of Oshkosh The conductivity values ranged from 356 to 3,880 µS/cm. One sample – outfall 16-844 – exceeded the 2,000 µS/cm action limit. However, since no other indicator parameters were out of range for this sample, it was not considered an illicit discharge. 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 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. 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. November 30, 2016 19 2016 Ongoing Screening Summary Report City of Oshkosh 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 microbial decay of plant and animal proteins. In addition, ammonia may be present in industrial discharges with a WPDES permit. Ammonia is also sometimes present in HVAC condensate, which is allowed to be discharged under the MS4 general 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. Four samples were at or above 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 1. November 30, 2016 20 2016 Ongoing Screening Summary Report City of Oshkosh Table 1 – IDDE potential of outfalls with ammonia detections Outfall Ammonia (ppm) IDDE Potential Reason 03-81 US1 1 Potential Petroleum sheen and odor in manhole; past petroleum and ammonia detections. 08-937 US1 1 Unlikely No other indicator parameters out of range. 15-1817 US1 3 Unlikely No other indicator parameters out of range. Sample collected from manhole sump with decaying vegetation. 16-142 US1 1 Potential Elevated ammonia and moderate gross solids (litter). 16-594 US1 0.25 Potential Detected ammonia and moderate gross solids (litter). 16-71 US1 0.5 Potential Detected ammonia and slight gross solids (litter, including syringes). The outfalls that were considered potential or obvious 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 or washwater dumped in or near a stormwater inlet. However, detergent can also be present in non-illicit discharges (as defined by the general permit and the municipality’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. November 30, 2016 21 2016 Ongoing Screening Summary Report City of Oshkosh 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. 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 None of the samples tested positive for detergents, so none of the samples were considered suspect due to detergent. 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 November 30, 2016 22 2016 Ongoing Screening Summary Report City of Oshkosh Obvious – visible and/or strong chemical evidence of current or past illicit discharge Of the 98 inspected outfalls, 71 were classified as unlikely, 27 were classified as potential, and none were classified as “obvious.” 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 2 – Outfalls with elevated illicit discharge classifications Outfall Classification Reason 01-520 Potential Persistent gross solids in upstream manhole (also present in 2009, 2010, 2011, 2012, 2013, 2014 and 2015). 01-642 Potential Persistent gross solids in upstream manhole (also present in 2015). 02-309 Potential Persistent gross solids in upstream manhole (also present in 2011 and 2015). 02-357 Potential Persistent gross solids in upstream manhole (also present in 2011, 2012, 2014 and 2015). 03-22 Potential Persistent gross solids in upstream manhole (also present in 2009, 2010, 2011, 2012, 2013, 2014 and 2015). 03-35 Potential Persistent gross solids in upstream manhole (also present in 2009, 2010, 2011, 2012, 2013 and 2015). 03-81 Potential Oil sheen/odor and elevated ammonia in upstream manhole, with gross solids (also present in 2009, 2010, 2014). 03-173 Potential Persistent gross solids in upstream manhole (also present in 2010, 2011, 2014 and 2015). 03-381 Potential Persistent gross solids in upstream manhole (also present in 2010, 2011, 2014 and 2015). 05-14 Potential Persistent gross solids in upstream manhole (also present in 2015). 06-52 Potential Persistent gross solids in upstream manhole (also present in 2010, 2011, 2014 and 2015). 06-221 Potential Persistent gross solids in upstream manhole (also present in 2010, 2011 and 2014). 06-1028 Potential Persistent gross solids in upstream manhole (also present in 2009, 2010, and 2012). 08-284 Potential Persistent gross solids in upstream manhole (also present in 2010, 2011, 2014 and 2015). 08-347 Potential Persistent gross solids in upstream manhole (also present in 2010, 2011, 2014 and 2015). 08-364 Potential Persistent gross solids in upstream manhole (also present in 2011 and 2015). 11-376 Potential Persistent gross solids in upstream manhole (also present in 2009, 2011, 2014 and 2015). 11-512 Potential Persistent gross solids in upstream manhole (also present in 2011, 2012, 2014 and 2015). 12-569 Potential Persistent gross solids in upstream manhole (also present in 2010, 2014 and 2015). 12-1328a Potential Elevated pH (also present in 2015). 15-636 Potential Persistent gross solids in upstream manhole (also present in 2011). November 30, 2016 23 2016 Ongoing Screening Summary Report City of Oshkosh Outfall Classification Reason 16-28 Potential Persistent gross solids in upstream manhole (also present in 2010). 16-71 Potential Persistent gross solids (including four syringes) in upstream manhole (also present in 2010). 16-142 Potential Persistent gross solids in upstream manhole (also present in 2010, 2011, 2012, 2014 and 2015). 16-201 Potential Persistent gross solids in upstream manhole (also present in 2010, 2011, 2012 and 2014). 16-533 Potential Persistent gross solids in upstream manhole (also present in 2010, 2011, 2014 and 2015). 16-594 Potential Persistent gross solids in upstream manhole (also present in 2010). A chart showing the number of outfalls inspected over the past eight years (starting with the initial screening in 2009) and the number of potential or obvious illicit discharges is shown in Figure 12. Figure 12 – Illicit discharge potential of inspected outfalls Upstream Manholes with Significant Floatable Debris During the 2016 ongoing screening program, 26 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 trapped on the surface of 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. November 30, 2016 24 2016 Ongoing Screening Summary Report City of Oshkosh 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. 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. Upstream manholes that were classified as “potential” sources of illicit discharge due to significant floatable debris during the 2009-2015 screening programs are shown in the table in Appendix D-1. The 2016 screening results are also shown. The outfalls with continuing observations of significant floatable debris were classified as priority outfalls in the revised ongoing screening program. This designation will cause them to be screened annually. These manholes should be cleaned several months prior to the scheduled 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-1. Outfall 03-81 (Pioneer Drive) Outfall 03-81 discharges near the railroad trestle at the north end of Pioneer Drive. The outfall is fully-submerged, and the MS4 mapping suggests that the end of the pipe may be 90 feet past the shoreline. As a result, the outfall is screened at the first upstream manhole. Figure 13 – Upstream manhole 03-81 US1 (2009) November 30, 2016 25 2016 Ongoing Screening Summary Report City of Oshkosh The outfall was first screened in 2009. The first upstream manhole was located on the south side of Pioneer Drive, behind the railroad control shed. When the manhole was opened, a strong smell of diesel fuel was detected inside the manhole. The manhole was also submerged, and had a significant amount of floatable debris, which appeared to be coated with oil and grease. Figure 14 – Floatable debris and grease in upstream manhole 03-81 US1 (2009) A sample was collected from upstream manhole 03-81 US1. The sample had a grayish-black color, and had a strong odor of diesel fuel. The sampling equipment and container were coated in grease from penetrating the floatable debris. None of the typical sampling parameters tested positive. Because of the obvious odor of diesel fuel and appearance of grease, no additional VOC or oil/grease tests were run. The railroad track ballast in the area showed no signs of stains or other leaks, so a railroad spill seemed unlikely. Additional tracking showed similar conditions in upstream manholes on E. 10th Avenue. The City and OMNNI believed that the illicit discharge evidence for this outfall was not caused by one significant event. Rather, it was likely caused by a gradual buildup of diesel fuel and oil/grease over many years, which became trapped in the downstream manholes. Upon discovering the problem, the City vacuumed the upstream manholes. A follow-up inspection of manhole 03-81 US1 revealed that the manhole was still fully-submerged, but the sample collected from the pool did not have a detectable odor. Because outfall 03-81 is classified as a Priority Outfall, it is screened annually. During some of the annual screening events, evidence of the petroleum discharge has been observed. The screening results are summarized in Table 3: Table 3 - Sample results from manhole 03-81 US1 Date Ammonia (ppm) Petroleum Gross Solids Illicit Discharge Potential 9/9/2009 N/A Strong odor, severe sheen/coated Severe Obvious 8/18/2010 0 Faint odor Moderate Potential 5/26/2011 N/A None Minor Unlikely 10/11/2011 0.25 None Minor Unlikely 10/9/2014 0.5 Faint odor, slight sheen Severe Obvious 9/23/2015 1 None Minor Unlikely 10/10/2016 1 Faint odor, moderate sheen Minor Potential November 30, 2016 26 2016 Ongoing Screening Summary Report City of Oshkosh Figure 15 – Upstream manhole 03-81 US1 (2016) There appears to be the potential for an ongoing intermittent discharge of petroleum from a source on E. 10th Street. OMNNI recommends that the City televise the storm sewer branches along this segment to identify any potential cross connections. It may also be necessary for City inspectors to inspect the areas where the storm sewer crosses private property to check for potential sources of industrial runoff that may enter the storm sewer system. Jetting the storm sewer system upstream of this outfall may help clean out any residual petroleum in the storm sewer. Additional information and maps related to this investigation are included in Appendix D-2. Outfall 12-1328a (Nolte Avenue detention basin) Outfall 12-1328a consists of a 42-inch reinforced concrete pipe that discharges the northeast corner of the detention basin located between W. Snell Road and Algoma Blvd. This segment of storm sewer was reconstructed in 2014 as part of the I-41 /Algoma Blvd (USH 45) overpass. This outfall replaces former outfall 12-1328, which was located at the west end of Fernau Avenue. Figure 16 – Outfall 12-1328a (10/10/2016) The outfall was first screened on September 23, 2015. During that screening, a trickle discharge was observed, with a white, silty substance. The silt was observed inside the pipe, on the apron, November 30, 2016 27 2016 Ongoing Screening Summary Report City of Oshkosh and on the riprap downstream of the apron. The sample that was collected from the flow had the following chemical indicator parameters outside of normal range: Ammonia: 1 ppm pH: 11.66 Conductivity: 2,470 µS/cm In addition, the sample reacted with the chlorine test strips to turn yellow, rather than their typical graduated shades of purple. This typically indicates that another chemical is present in the sample that interferes with the test strips. The Illicit Discharge Coordinator was notified of the discharge on September 25, 2015. The construction plans for the updated storm sewer were requested to aid with the tracking of the discharge. OMNNI traced the discharge on September 28, 2015. A sample from the outfall had a pH of 9.73. Upstream tracing was conducted primarily using visible flow and white staining, and supplemented with pH samples. The discharge was traced to a 6-inch pipe that was tapped into a curb inlet (582A) near the intersection of Walter Street and Fernau Avenue. The pipe appeared to be coming from the Carew concrete plant. A sample collected from this pipe had a pH of 12.28, and white staining was present in the pipe, confirming that it was the source of the discharge. Figure 17 – Inlet 582A (9/28/2015) November 30, 2016 28 2016 Ongoing Screening Summary Report City of Oshkosh Figure 18 – Pipe discharging into inlet 582A (9/28/2015) The Illicit Discharge Coordinator was notified of this pipe on September 28, 2015, and OMNNI and City personnel met with a representative of Carew Concrete on September 29, 2015 to attempt to identify the source of the discharge. No upstream inlets or catchbasins were located on the property. City personnel inserted a temporary plug in the end of the pipe to stop the discharge. During the 2016 screening on October 10, 2016, it was observed that the pipe in the upstream catchbasin had been permanently plugged. No flow was leaving the upstream catchbasin. A trickle flow was present at the outfall, and the sample that was collected had a pH of 9.45, which still exceeded the 9.0 action limit. No ammonia was detected, and conductivity was within normal parameters (880 µS/cm). Table 4 - Sample results from outfall 12-1328a Date Ammonia (ppm) pH Conductivity (µS/cm) 9/23/2015 1 11.66 2,470 10/10/2016 0 9.45 880 Because of the industrial nature of the drainage basin and the identified illicit discharge, outfall 12-1328a was classified as a priority outfall, and will be screened annually. If the elevated pH is due to residual contamination in the pipe, the pH should continue to decrease with future screenings. This process could be accelerated if the City jets the storm sewer between inlet 582A and the outfall. Additional maps and information related to this investigation are included in Appendix D-3. STATUS OF PRIOR YEAR’S ISSUES During the 2015 ongoing screening program, 98 outfalls were screened. The screening revealed 20 potential illicit discharges and one obvious illicit discharge. Those outfalls identified as potential or obvious illicit discharges were typically recommended to be rescreened in the following year, regardless of their priority status or inspection schedule. Table 5 summarizes the issues that were identified in 2015, along with the conditions that were observed during the 2016 rescreening. Follow-up actions for outfalls that are still listed as potential or obvious illicit discharges are discussed in greater detail in the “Potential Illicit November 30, 2016 29 2016 Ongoing Screening Summary Report City of Oshkosh Discharges” section of this report. If the rescreening resulted in an unlikely illicit discharge, the outfall will return to its normal screening schedule.

Potential 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. November 30, 2016 31 2016 Ongoing Screening Summary Report City of Oshkosh Damage Three outfalls showed signs of damage that may require attention in the near future. Observed damage included corrosion on corrugated metal pipes, pipe joint displacement, and displaced manhole castings. The outfall damage that was observed during the ongoing screening program is summarized in Table 6. Table 6 – Outfalls with damage Outfall Severity Description 03-293 Minor Corrosion of corrugated metal pipe. 06-221 US1 Minor Casting displaced 2 inches. 14-999 Minor 4” joint displacement at end section of pipe. The outfall damage is shown in the photos that follow. The locations of the damaged outfalls are shown on the map in Appendix C.

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. Table 7 – Outfalls with deposition Outfall Severity Description 11-1097 US1 Minor 5” of sediment in manhole. 13-1098 Severe 16” of sediment at end of pipe. 13-1758 Moderate 13” of sediment on apron. 14-1514 Moderate 10” of stone in pipe. 15-2409 Minor 1” of sediment in pipe and on apron. 16-381 Moderate 10” of sediment on submerged apron. 16-47 US2 Minor 3” of sediment in bottom of catchbsasin.

November 30, 2016 34 2016 Ongoing Screening Summary Report City of Oshkosh Graffiti Graffiti was observed in or around two outfalls. The graffiti was not severe, but should probably be monitored to make sure that it does not become more severe. The graffiti that was observed during the ongoing screening program is summarized in Table 8. Table 8 – Outfalls with graffiti Outfall Severity Description 12-569 Minor Graffiti on bridge abutment adjacent to outfall. 16-1508 Moderate Graffiti on bridge abutment adjacent to outfall. The graffiti is shown in the photos that follow. The locations of the outfalls with graffiti are shown on the map in Appendix C. Figure 29 – Graffiti near outfall 12-569 Figure 30 – Graffiti near outfall 16-1508 2017 ONGOING SCREENING PROGRAM The 2016 outfall screening was conducted using the revised Ongoing Screening Program as a guide. All of the outfalls that had been identified as priority outfalls had been screened, along with a subset of the non-priority outfalls. Based on the field observations, the overall outfall classification was revised to: 46 priority outfalls 80 non-priority major outfalls 299 non-priority non-major outfalls Using the screening frequency specified in the Ongoing Screening Program, the following number of outfalls are recommended to be screened for the 2017 outfall screening program: 46 priority outfalls 15 non-priority major outfalls 30 non-priority non-major outfalls November 30, 2016 35 2016 Ongoing Screening Summary Report City of Oshkosh In addition, the 11 non-priority outfalls that had potential or obvious illicit discharges will also be rescreened, bringing the 2017 total to 102 outfalls. A table summarizing the recent inspection history of the MS4 outfalls, along with the proposed schedule, is included in Appendix E. CONCLUSION OMNNI assisted the City of Oshkosh with the 2016 ongoing screening of the MS4 outfalls, as required by the MS4 permit. A total of 98 outfalls were screened, along with upstream monitoring locations when necessary. Of those 98 outfalls, 71 exhibited unlikely potential of past illicit discharges, and 27 were classified as “potential.” These results are summarized in Figure 31: Figure 31 – Illicit discharge potential Those outfalls classified as “potential” or “obvious” should be given special attention in the ongoing screening program. In particular, the following actions are recommended: 1. For the 26 manholes with observed gross solids, the City should remove the accumulated debris (via vacuum truck or manual methods) at least six weeks prior to the 2017 screening. This will help determine if the discharge of the solid waste into the storm sewer is ongoing. (Additional upstream manholes could also be inspected and cleaned if necessary.) 2. Jet the storm sewer upstream of outfall 03-81 to remove any accumulated petroleum residue, gross solids and sediment. November 30, 2016 36 2016 Ongoing Screening Summary Report City of Oshkosh 3. Perform a field investigation of the storm sewer upstream of outfall 03-81 (including televising, if necessary) to identify potential cross connections or other sources of the petroleum discharge. 4. Jet the storm sewer upstream of outfall 12-1328a to remove any remaining residue that may be contributing to the elevated pH in the discharge. The ongoing screening also identified 3 outfalls with structural damage, 7 with deposition, and 2 with graffiti. While none of these posed an immediate danger, the City may want to address these issues as part of the regular storm sewer system maintenance. 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 described in this report.

I am approximately 80% complete. I plan on finishing the scheduled outfalls on Monday of next week. So far, I have identified only one potential illicit discharge, and I’ll need you to confirm if it is actually a city outfall. I was investigating the area around W Fernau Ave and Walter St. The city’s storm sewer mapping still shows the old storm sewer, from before the Fernau/Algoma roundabout. This storm sewer originally discharged at outfall 12-1328, which no longer exists. I decided to spend a few minutes in the field attempting to determine the layout of the new storm sewer and the location of the new outfall. I identified an outfall in the northeast corner of the detention basin near Nolte Ave and Algoma Blvd. Based on the configuration of the manholes and curb inlets, it appeared that this might be the replacement for outfall 12-1328, so I did an initial screening. During the screening, I noticed a white discharge coming from the outfall. The trickle discharge appeared to have a fine sediment in it, similar to chalk or silt. The white color was present in the flow, and had stained the pipe, apron, and downstream riprap. There were also pools of the white discharge in the riprap channel leading to the detention basin. A sample was collected and tested for chemical indicator parameters: • Ammonia was 1 ppm (at the threshold for a potential illicit discharge). • The chlorine test strips turned bright yellow, rather than a shade of purple. This typically is a result of another dissolved chemical interfering with the test strips. • No detergent was detected. • Conductivity was 2470 µS/mS, which shows a fairly high concentration of dissolved ionic material. (Anything over 2000 µS/mS is suspect for wastewater/washwater.) • The pH was 11.66, which is extremely high. (Typical outfall samples have a pH of 6-9.) I located the curb inlet at the southwest corner of Nolte Avenue and Walter Street, which appeared to be the first upstream structure. I did not observe a flow in this structure, but it was difficult to see the flowline from the south. At this time, I have a few questions for the City: 1. Can you confirm that this is the City’s outfall (not County, State, etc.)? 2. Is this outfall the replacement for outfall 12-1328, which was relocated due to the roundabout construction? 3. Is there any updated storm sewer mapping available for this area? 4. After I finish the scheduled outfall screening on Monday, would you like me to spend some time attempting to track the discharge (based on flow and/or stains)? 5. Are you aware of any facilities along Walter or Fernau (west of the Fernau detention basin) that might be a source for this white alkaline material? 2 Jason Weis, P.E., GISP Project Manager / Geospatial Manager OMNNI Associates, Inc.

The staining and elevated pH discharge was observed at the outfall, and a surface water sample from the detention basin also had an elevated pH (9.73). The white stain was present at the upstream inlet on Walter Road, and clearly came from the south. The white stain in the manhole near Walter Road and Walter Court reinforced that the discharge was coming from the direction of Fernau Ave. The new storm sewer branches to the northeast and southwest at Fernau Ave. Due to traffic issues, the manhole at the intersection of Walter and Fernau could not be inspected to determine which branch was contributing the stain. Several of the inlets and manholes from the “original” Fernau Avenue storm sewer (northeast branch) were inspected, and there were no signs of white stains. The first “new” manhole northeast of the intersection was inspected, and there were also no signs of white stains, suggesting that the discharge was coming from the southwest branch. The first manhole southwest of the intersection (#562) was wet and had some of the white substance in it. The stain appeared to come from the inlet to the east. The inlet on the west side of Fernau (582B) was dry and clean. The inlet on the east side of Fernau (582A) was wet and had the white substance. Upon further inspection of the inlet, a 6” pipe was identified protruding through the back side (east/south) of the structure, with white staining and a trickle flow. This pipe appeared to originate from the property to the east (Carew). A sample was collected from this trickle flow, and the pH was 12.23. The elevated pH, along with the white staining from the pipe, indicate that this is the likely source of the discharge. As a confirmation, the next set of inlets upstream (south) of this manhole were inspected (immediately north of Stillman Road). The inlet on the east side of the road had water in the sump. A sample was collected from this pool, and the pH was 7.4, which is in the typical range for stormwater. This seems to indicate that the discharge is limited to the area around manhole 562, and specifically from the 6” pipe in inlet 562A. I have attached a few additional photos to this email, along with a map showing the general layout and investigation findings. It is recommended that the City investigate the origin of this 6” pipe, along with any potential sources of the illicit discharge on the Carew property. If the City needs assistance with this tracking, OMNNI would be happy to help. Please keep OMNNI updated on any investigation activities for this discharge, along with any findings or resolutions, so we can include them in the Summary Report that we will prepare later this year.

Cc: Brian Wayner; Lyons, Kris Subject: RE: Potential illicit discharge - Nolte Avenue detention basin The probable source of the white alkaline discharge has been located. There is a 6" pipe stubbed into the back of curb inlet 582A (from the plan sheet you sent me). The inlet is on the east side if Fernau, just south of Walter. The pipe appears to come from the Carew property. A sample collected from this pipe had a pH of 12.23. There was also white staining coming from this pipe. Therefore, this should be the location where the discharge is entering the MS4. The City will likely need to determine the source of this pipe on the Carew property. OMNNI can assist if needed. Note that the pH of the water in the downstream detention basin was 9.73, which is very high for surface water. I have attached a few pbotos. I will send more detailed information once I get back to the office this afternoon. Feel free to call if you have any questions.

The plans did not show the section of the storm sewer being reconnected to the east. I am unsure how it was reconnected but suspect it was one of the two red dashed lines I drew on the attached. The plans also do not show storm sewer for Walter Ct, but inlet exist. My best suspect for a source is Carew Concrete located on the south/east side of Fernau Ave at the Walter Rd intersection.

Cc:Brian Wayner; Lyons, Kris Subject:RE: Potential illicit discharge - Nolte Avenue detention basin Jason, Thank you for the summary. To confirm our phone conversation, we will meet Mike Tews from Carew Concrete onsite at 1:00 p.m. to review this, and see if the source can be located. Please bring your gear to assist. Please charge on the “tracking” task. Streets Division will meet us at the intersection of Fernau and Walter with the push camera to assist in looking up the line tapped into the back of the inlet. Thank you, James From: Jason Weis [mailto:Jason.Weis@omnni.com] Sent: Monday, September 28, 2015 3:15 PM To: Gohde, Steven M.; Rabe, James E. Cc: Brian Wayner; Lyons, Kris Subject: RE: Potential illicit discharge - Nolte Avenue detention basin I have attached a map that summarizes the tracking activities from today. The staining and elevated pH discharge was observed at the outfall, and a surface water sample from the detention basin also had an elevated pH (9.73). The white stain was present at the upstream inlet on Walter Road, and clearly came from the south. The white stain in the manhole near Walter Road and Walter Court reinforced that the discharge was coming from the direction of Fernau Ave. The new storm sewer branches to the northeast and southwest at Fernau Ave. Due to traffic issues, the manhole at the intersection of Walter and Fernau could not be inspected to determine which branch was contributing the stain. Several of the inlets and manholes from the “original” Fernau Avenue storm sewer (northeast branch) were inspected, and there were no signs of white stains. The first “new” manhole northeast of the intersection was inspected, and there were also no signs of white stains, suggesting that the discharge was coming from the southwest branch. The first manhole southwest of the intersection (#562) was wet and had some of the white substance in it. The stain appeared to come from the inlet to the east. The inlet on the west side of Fernau (582B) was dry and clean. The inlet on the east side of Fernau (582A) was wet and had the white substance. Upon further inspection of the inlet, a 6” pipe was identified protruding through the back side (east/south) of the structure, with white staining and a trickle flow. This pipe appeared to originate from the property to the east (Carew). A sample was collected from this trickle flow, and the pH was 12.23. The elevated pH, along with the white staining from the pipe, indicate that this is the likely source of the discharge. As a confirmation, the next set of inlets upstream (south) of this manhole were inspected (immediately north of Stillman Road). The inlet on the east side of the road had water in the sump. A sample was collected from this pool, and the pH was 7.4, which is in the typical range for stormwater. This seems to indicate that the discharge is limited to the area around manhole 562, and specifically from the 6” pipe in inlet 562A. 2 I have attached a few additional photos to this email, along with a map showing the general layout and investigation findings. It is recommended that the City investigate the origin of this 6” pipe, along with any potential sources of the illicit discharge on the Carew property. If the City needs assistance with this tracking, OMNNI would be happy to help. Please keep OMNNI updated on any investigation activities for this discharge, along with any findings or resolutions, so we can include them in the Summary Report that we will prepare later this year. If you have any questions, please let me know. Jason Weis, P.E., GISP Project Manager / Geospatial Manager OMNNI Associates, Inc.

Cc: Brian Wayner; Lyons, Kris Subject: RE: Potential illicit discharge - Nolte Avenue detention basin The probable source of the white alkaline discharge has been located. There is a 6" pipe stubbed into the back of curb inlet 582A (from the plan sheet you sent me). The inlet is on the east side if Fernau, just south of Walter. The pipe appears to come from the Carew property. A sample collected from this pipe had a pH of 12.23. There was also white staining coming from this pipe. Therefore, this should be the location where the discharge is entering the MS4. The City will likely need to determine the source of this pipe on the Carew property. OMNNI can assist if needed. Note that the pH of the water in the downstream detention basin was 9.73, which is very high for surface water. I have attached a few pbotos. I will send more detailed information once I get back to the office this afternoon. Feel free to call if you have any questions.

The plans did not show the section of the storm sewer being reconnected to the east. I am unsure how it was reconnected but suspect it was one of the two red dashed lines I drew on the attached. The plans also do not show storm sewer for Walter Ct, but inlet exist. My best suspect for a source is Carew Concrete located on the south/east side of Fernau Ave at the Walter Rd intersection. Please investigate this discharge. If you need any City staff assistance please let us know.

Cc: Brian Wayner Subject: Potential illicit discharge - Nolte Avenue detention basin James/Steve: I conducted outfall inspections on Tuesday, Wednesday and Thursday this week. I am approximately 80% complete. I plan on finishing the scheduled outfalls on Monday of next week. So far, I have identified only one potential illicit discharge, and I’ll need you to confirm if it is actually a city outfall. I was investigating the area around W Fernau Ave and Walter St. The city’s storm sewer mapping still shows the old storm sewer, from before the Fernau/Algoma roundabout. This storm sewer originally discharged at outfall 12-1328, which no longer exists. I decided to spend a few minutes in the field attempting to determine the layout of the new storm sewer and the location of the new outfall. I identified an outfall in the northeast corner of the detention basin near Nolte Ave and Algoma Blvd. Based on the configuration of the manholes and curb inlets, it appeared that this might be the replacement for outfall 12-1328, so I did an initial screening. During the screening, I noticed a white discharge coming from the outfall. The trickle discharge appeared to have a fine sediment in it, similar to chalk or silt. The white color was present in the flow, and had stained the pipe, apron, and downstream riprap. There were also pools of the white discharge in the riprap channel leading to the detention basin. A sample was collected and tested for chemical indicator parameters: • Ammonia was 1 ppm (at the threshold for a potential illicit discharge). • The chlorine test strips turned bright yellow, rather than a shade of purple. This typically is a result of another dissolved chemical interfering with the test strips. • No detergent was detected. • Conductivity was 2470 µS/mS, which shows a fairly high concentration of dissolved ionic material. (Anything over 2000 µS/mS is suspect for wastewater/washwater.) • The pH was 11.66, which is extremely high. (Typical outfall samples have a pH of 6-9.) I located the curb inlet at the southwest corner of Nolte Avenue and Walter Street, which appeared to be the first upstream structure. I did not observe a flow in this structure, but it was difficult to see the flowline from the south. At this time, I have a few questions for the City: 1. Can you confirm that this is the City’s outfall (not County, State, etc.)? 4 2. Is this outfall the replacement for outfall 12-1328, which was relocated due to the roundabout construction? 3. Is there any updated storm sewer mapping available for this area? 4. After I finish the scheduled outfall screening on Monday, would you like me to spend some time attempting to track the discharge (based on flow and/or stains)? 5. Are you aware of any facilities along Walter or Fernau (west of the Fernau detention basin) that might be a source for this white alkaline material?
