E January 25, 2019 1 2018 Ongoing Screening Summary Report City of Oshkosh EXECUTIVE SUMMARY During the fall of 2018, 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 91 of the approximately 428 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 35 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. January 25, 2019 2 2018 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 428 outfalls, including: • 94 major outfalls • 241 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 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) January 25, 2019 3 2018 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) October 2017 – 2017 Ongoing Screening 101 outfalls screened, with 25 potential illicit discharges identified. City of Oshkosh Ongoing Screening Summary Report – 2017 Inspection Year (January 25, 2018) October 2018 – 2018 Ongoing Screening 91 outfalls screened, with 35 potential illicit discharges identified. City of Oshkosh Ongoing Screening Summary Report – 2018 Inspection Year (January 25, 2018) (This document) 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 45 priority outfalls. The 2018 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 2018 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, 2019. 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 January 25, 2019 4 2018 Ongoing Screening Summary Report City of Oshkosh 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, 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 January 25, 2019 5 2018 Ongoing Screening Summary Report City of Oshkosh 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. RAINFALL AND FLOW Rainfall Weather data was obtained from the Weather Underground website. Personal weather station KWIOSHKO31 (“Village Ln”) is located near the intersection of Village Lane and Donegal Court in the City of Oshkosh. The conditions at this weather station were considered representative of the weather in the City of Oshkosh for the 2018 ongoing screening. The location of the weather station is shown in Figure 1. Figure 1 – Location of weather station for weather history January 25, 2019 6 2018 Ongoing Screening Summary Report City of Oshkosh The weather history from September 22, 2018 (one month prior to the start of inspections) through November 3, 2018 (one week after the completion of inspections) from this weather station is shown in Figure 2. Figure 2 – Fall 2018 weather history (Weather Underground) January 25, 2019 7 2018 Ongoing Screening Summary Report City of Oshkosh Outfall inspections were conducted in the City of Oshkosh on October 22, 24 and 25, 2018. (Follow-up inspections were conducted on October 26 and 29). 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. The distribution of the flow intensity of the outfalls (not including upstream sampling points) is shown in Figure 4. January 25, 2019 8 2018 Ongoing Screening Summary Report City of Oshkosh Figure 4 – Flow intensity at outfall Submerged outfalls, along with their sampling protocol, are described in the next section. 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. January 25, 2019 9 2018 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 91 inspected outfalls, 30 were partially submerged, and 46 were fully submerged (Figure 5). Of the 46 fully submerged outfalls, 36 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 January 25, 2019 10 2018 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 January 25, 2019 11 2018 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. January 25, 2019 12 2018 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 regarding 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 January 25, 2019 13 2018 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 2018, 23 outfalls were classified as potential illicit discharge because of the presence of moderate or severe gross solids in their upstream manholes, and one was classified as potential due to significant amounts of dry gross solids (litter) inside the outfall pipe. 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. January 25, 2019 14 2018 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 80 stormwater samples were collected and analyzed as part of the ongoing screening process in 2018 – 14 were from flow streams, and 66 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 January 25, 2019 15 2018 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 6.55 to 9.04. One sample (12-1328a) was outside of the 6.0-9.0 normal range. Because the sample also had elevated pH in 2015-2017, 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. Surface temperatures were typically 45 °F or warmer during the inspections. As a result, the “normal” temperature range was set at 45 °F to 90 °F. Any samples outside of this range could contain flow other than stormwater runoff. January 25, 2019 16 2018 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 48 to 60 °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 January 25, 2019 17 2018 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 The conductivity values ranged from 314 to 3,300 µS/cm. Two samples were at or above the 2,000 µS/cm action limit. Based on other factors, those outfalls may or may not have been 1 USEPA: Water-Monitoring & Assessment – Conductivity (http://water.epa.gov/type/rsl/monitoring/vms59.cfm) January 25, 2019 18 2018 Ongoing Screening Summary Report City of Oshkosh classified as potential illicit discharges. The illicit discharge potential of the outfalls with elevated conductivities are summarized in Table 2. Table 1 – IDDE potential of outfalls with elevated conductivity Outfall Ammonia (ppm) IDDE Potential Reason 06-253 US1 2,280 Potential Elevated ammonia and conductivity in manhole pool. 16-844 3,300 Potential Elevated conductivity and detergent detection in manhole pool. The outfalls that were considered potential or obvious illicit discharges are discussed in more detail in the Potential Illicit Discharges section of this report. 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. January 25, 2019 19 2018 Ongoing Screening Summary Report City of Oshkosh 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 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. January 25, 2019 20 2018 Ongoing Screening Summary Report City of Oshkosh Figure 10 – Ammonia sample results The ammonia values ranged from 0 to 3 ppm. Two 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 2. Table 2 – IDDE potential of outfalls with ammonia detections Outfall Ammonia (ppm) IDDE Potential Reason 08-937 US1 1 Unlikely No other indicator parameters out of range. Assumed to be decomposition product. 06-253 US1 3 Potential Elevated ammonia and conductivity in manhole pool. 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: January 25, 2019 21 2018 Ongoing Screening Summary Report City of Oshkosh • 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. 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. January 25, 2019 22 2018 Ongoing Screening Summary Report City of Oshkosh Results The detergent results for the samples are shown in Figure 12. Figure 12 – Detergent sample results The detergent values ranged from 0 to 0.55 mg/L, with ten samples showing positive detections of detergent. 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 detergent detections are summarized in Table 3.

The outfalls that were considered potential or obvious illicit discharges are discussed in more detail in the Potential Illicit Discharges section of this report. January 25, 2019 23 2018 Ongoing Screening Summary Report City of Oshkosh 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 91 inspected outfalls, 56 were classified as unlikely, 35 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 4 – 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, 2015, 2016 and 2017). 02-309 Potential Persistent gross solids in upstream manhole (also present in 2011, 2015, 2016 and 2017). 02-357 Potential Persistent gross solids in upstream manhole (also present in 2011, 2012, 2014, 2015, 2016 and 2017). 03-22 Potential Persistent gross solids in upstream manhole (also present in 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016 and 2017). 03-35 Potential Persistent gross solids in upstream manhole (also present in 2009, 2010, 2011, 2012, 2013, 2015, 2016, and 2017). 03-81 Potential Persistent gross solids in upstream manhole (also present in 2009, 2010, 2014, 2016 and 2017).

A chart showing the number of outfalls inspected over the past ten years (starting with the initial screening in 2009) and the number of potential or obvious illicit discharges is shown in Figure 13. January 25, 2019 25 2018 Ongoing Screening Summary Report City of Oshkosh Figure 13 – Illicit discharge potential of inspected outfalls The outfalls with potential or obvious illicit discharges are described in more detail below. Upstream Manholes with Significant Floatable Debris During the 2018 ongoing screening program, 23 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. 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 2009-2017 screening programs are shown in the table in Appendix D. The 2018 screening results are also shown. January 25, 2019 26 2018 Ongoing Screening Summary Report City of Oshkosh 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. Outfall 06-253 (Campbell Road) Outfall 06-253 consists of a 34x53 inch reinforced concrete pipe (RCP) that discharges into the Fox River at the end of the extension of Campbell Road. The pipe may be the effluent pipe for the wastewater treatment plant. The pipe is fully submerged. Figure 14 - Outfall 06-253 (2018) Because the outfall is fully submerged, it is screened at the upstream manhole (06-253 US1) located approximately 266 feet upstream of the outfall, in the senior center parking lot. Figure 15 – Upstream manhole 06-253 US1 (2018) January 25, 2019 27 2018 Ongoing Screening Summary Report City of Oshkosh During the 2017 screening, the sample collected from manhole 06-253 US1 had an elevated level of ammonia. No other parameters were outside of the normal range, although conductivity was approaching the 2,000 µS/cm action level. Because this outfall is a priority outfall, it was rescreened as part of the 2018 screening program. The screening showed that the ammonia was once again elevated, and conductivity was above the 2,000 µS/cm action level. The samples collected from the upstream manhole during prior screenings are summarized in Table 5: Table 5 - Sample results from outfall 06-253 Date Location Ammonia (ppm) Detergent (mg/L) pH Conductivity (µS/cm) 9/10/2009 Upstream N/A 0 6.92 N/A 8/18/2010 Upstream 0 0 7.05 N/A 9/23/2015 Upstream 0 0 7.53 1,220 10/18/2016 Upstream 0 0 7.01 1,228 10/19/2017 Upstream 3 0 7.15 1,990 10/24/2018 Upstream 3 0 7.27 2,280 Because this outfall is classified as a priority outfall, it is scheduled to be rescreened in 2019. Additional information related to the investigation of this outfall is contained in Appendix D. Outfall 06-473 (Mason Street) A large metal box culvert runs from 9th Avenue (Franklin Elementary School) to Witzel Avenue (east of Lourdes High School). Because this culvert diverts a stream, it is considered a Water of the State, and outfalls are located wherever storm sewer lines discharge to it. Outfall 06-473 is located where the 24” storm sewer from Mason Street discharges to the culvert from the south, just south of W. 5th Avenue. Because it was not possible to screen at the actual junction, the outfall was screened at the nearest manhole. Figure 16 - Outfall 06-473 (2018) During the 10/25/2018 screening, the outfall was partially submerged with a slight flow. Detergent was detected in the sample that was collected. Because of this, a second sample was collected on 10/26/2018, which also contained detergent. January 25, 2019 28 2018 Ongoing Screening Summary Report City of Oshkosh The samples summarized in Table 6: Table 6 - Sample results from outfall 06-473 Date Location Ammonia (ppm) Detergent (mg/L) pH Conductivity (µS/cm) 10/25/2018 Manhole 0 0.5 8.15 1,289 10/26/2018 Manhole 0 0.3 8.25 1,080 No apparent sources were readily identified during the field screening. Because of additional detergent detections in the area, this detergent detection could be related to the discharge at outfall 13-471 at W. 9th Avenue. Because this outfall is a non-priority non-major outfall, it would normally be scheduled to be screened in 10 years. However, because of the potential illicit discharge, it will be scheduled to be rescreened in 2019. If the detergent is still present, and additional tracking will be performed. Additional information related to the investigation of this outfall is contained in Appendix D. Outfall 06-494 (W. 4th Avenue) A large metal box culvert runs from 9th Avenue (Franklin Elementary School) to Witzel Avenue (east of Lourdes High School). Because this culvert diverts a stream, it is considered a Water of the State, and outfalls are located wherever storm sewer lines discharge to it. Outfall 06-494 is located where the 36x58” storm sewer from W. 4th Avenue discharges to the culvert from the west, between Mason Street and Sawyer Street. Because it was not possible to screen at the actual junction, the outfall was screened at the nearest manhole, at the intersection of W. 4th Avenue and Mason Street. Figure 17 - Outfall 06-494 US1 (2018) During the 10/25/2018 screening, the outfall was partially submerged with indeterminate flow. Detergent was detected in the sample that was collected. Because of this, a second sample was collected on 10/26/2018, which also contained detergent.

Because this outfall is a non-priority non-major outfall, it would normally be scheduled to be screened in 10 years. However, because of the potential illicit discharge, it will be scheduled to be rescreened in 2019. If the detergent is still present, and additional tracking will be performed. Additional information related to the investigation of this outfall is contained in Appendix D. Outfall 06-610 (W. 5th Avenue) A large metal box culvert runs from 9th Avenue (Franklin Elementary School) to Witzel Avenue (east of Lourdes High School). Because this culvert diverts a stream, it is considered a Water of the State, and outfalls are located wherever storm sewer lines discharge to it. Outfall 06-610 is located where the 15” storm sewer from W. 5th Avenue discharges to the culvert from the west. Because it was not possible to screen at the actual junction, the outfall was screened at the nearest manhole, at the intersection of W. 5th Avenue and Mason Street. Figure 18 - Outfall 06-610 (2018) During the 10/25/2018 screening, the outfall was partially submerged with indeterminate flow. Detergent was detected in the sample that was collected. Because of this, a second sample was collected on 10/26/2018, which also contained detergent. The samples summarized in Table 8: Table 8 - Sample results from outfall 06-473 Date Location Ammonia (ppm) Detergent (mg/L) pH Conductivity (µS/cm) 10/25/2018 Manhole 0 0.5 8.09 1,272 10/26/2018 Manhole 0 0.45 8.17 1,215 No apparent sources were readily identified during the field screening. Because of additional detergent detections in the area, this detergent detection could be related to the discharge at outfall 13-471 at W. 9th Avenue. Because this outfall is a non-priority non-major outfall, it would normally be scheduled to be screened in 10 years. However, because of the potential illicit discharge, it will be scheduled to be rescreened in 2019. If the detergent is still present, and additional tracking will be performed.

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 19 – Outfall 12-1328a (2018) 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, 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. 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. January 25, 2019 31 2018 Ongoing Screening Summary Report City of Oshkosh Figure 20 – Inlet 582A (9/28/2015) Figure 21 – 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. The samples collected from the outfall and/or upstream manhole during prior screenings are summarized in Table 9: Table 9 - Sample results from outfall 12-1328a Date Location Ammonia (ppm) Detergent (mg/L) pH Conductivity (µS/cm) 9/23/2015 Outfall 1 0 11.66 2,470 10/10/2016 Outfall 0 0 9.45 880 10/18/2017 Outfall 0 0 9.23 1,563 10/24/2018 Outfall 0 0 9.04 792 January 25, 2019 32 2018 Ongoing Screening Summary Report City of Oshkosh 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 information related to the investigation of this outfall is contained in Appendix D. Outfall 13-471 (W. 9th Avenue) Outfall 13-471 consists of a 48x76 elliptical concrete pipe that discharges to a channel north of W. 9th Avenue. After flowing approximately 400 feet, the channel enters the large metal box culvert that flows north to Witzel Avenue and discharges east of Lourdes High School. Figure 22 - Outfall 13-471 (2018) During the 10/25/2018 screening, the outfall was partially submerged with significant flow. A sample was collected from the flow, which tested positive for detergent. Because of this, a second sample was collected on 10/26/2018, which also contained detergent. The samples summarized in Table 10: Table 10 - Sample results from outfall 13-471 Date Location Ammonia (ppm) Detergent (mg/L) pH Conductivity (µS/cm) 9/4/2009 Outfall N/A 0 8.38 N/A 6/13/2012 Outfall 0 0 7.91 1,579 10/25/2018 Outfall 0 0.5 8.16 1,209 10/26/2018 Outfall 0 0.4 8.18 1,183 No apparent sources were readily identified during the field screening. This detergent discharge may be related to the detections at downstream outfalls 06-473, 06-494 and 06-610. Because this outfall is a non-priority major outfall, it would normally be scheduled to be screened in 5 years. However, because of the potential illicit discharge, it will be scheduled to be rescreened in 2019. If the detergent is still present, and additional tracking will be performed. Additional information related to the investigation of this outfall is contained in Appendix D. Outfall 13-2332 (Fox Tail Ln) Outfall 13-2332 consists of a 33x60 elliptical concrete pipe that discharges to a channel north of Fox Tail Lane, near Traeger Middle School. January 25, 2019 33 2018 Ongoing Screening Summary Report City of Oshkosh Figure 23 - Outfall 13-2332 (2018) Because the outfall was partially submerged during the 10/24/2018 screening, it was screened at the upstream catchbasin (13-2332 US1) located approximately 30 feet upstream of the outfall. Figure 24 – Upstream manhole 13-2332 US1 (2018) During the 10/24/2018 screening, the outfall was partially submerged with slight flow. A sample was collected from the flow, which tested positive for detergent. Because of this, a second sample was collected on 10/26/2018, which also contained detergent. The samples summarized in Table 11: Table 11 - Sample results from outfall 13-2332 Date Location Ammonia (ppm) Detergent (mg/L) pH Conductivity (µS/cm) 9/3/2009 Manhole N/A 0 8.04 N/A 6/12/2012 Manhole 0 0 7.64 982 10/24/2018 Manhole 0 0.3 7.56 1,107 10/26/2018 Manhole 0 0.35 7.66 1,082 Additional tracking was conducted on 10/29/2018. (The area received 0.2 inches of rain the previous day, which should not have impacted the results.) During this tracking, the flow was traced back to manhole 13-2334, located between W. 20th Avenue and Montclair Place. A sample from the pipe entering the manhole from the south had a detergent concentration of 0.80 mg/L, indicating that the source of the detergent is likely from one of the branches along W. 20th Avenue or S. Oakwood Road. January 25, 2019 34 2018 Ongoing Screening Summary Report City of Oshkosh Because this outfall is a non-priority non-major outfall, it would normally be scheduled to be screened in 10 years. However, because of the potential illicit discharge, it will be scheduled to be rescreened in 2019. If the detergent is still present, and additional tracking will be performed. Additional information related to the investigation of this outfall is contained in Appendix D. Outfall 13-3774 (Armory Pond) Outfall 13-3774 consists of a 66” reinforced concrete pipe that discharges to the west side of the recently-constructed Armory pond, near the end of Menard Drive. The drainage area for this outfall consists primarily of the commercial area east of S. Koeller Street, between 9th Street and 2th Street. Figure 25 - Outfall 13-3774 (2018) A sample was collected from the trickle flow from the outfall on 10/25/2018. Detergent was detected in this sample at 0.45 mg/L. Because of this detection, the outfall flow was resampled on 10/26/2018, and the detergent concentration was 0.85 mg/L. No other indicator parameters were above action limits. Preliminary tracking activities were conducted on 10/29/2018. (The area received 0.2 inches of rain the previous day, which may have impacted the results.) Screening started at the first upstream manhole, which was the large vault immediately north of the outfall. Figure 26 – Upstream manhole 13-3774 (2018) January 25, 2019 35 2018 Ongoing Screening Summary Report City of Oshkosh A sample was collected from the flowline of the manhole, at the upstream end of the 66” outfall pipe. This sample contained no detergent. However, suds were noted on the bench at the outlet of the pipe entering the manhole from the west. The detergent test for the sample collected from this pool was also negative. Figure 27 – Flowline of manhole 13-3774 (2018) Figure 28 – Sample from west – manhole 13-3774 (2018) Additional upstream manholes in the Shopko parking lot and on Menard Drive were also screened. If any flows were present, they were not sufficient to collect a sample for detergent testing. As a result, no suspected source or direction was determined for the detergent in the flow.

If detergent is still present, additional upstream tracking will be performed. Additional information related to the investigation of this outfall is contained in Appendix D. Outfall 16-660 (Fall Creek Lane) Outfall 16-660 consists of a 21-inch RCP that discharges into the south end of a detention basin between Westhaven Drive and Sawyer Creek. The drainage basin for the storm sewer is primarily a residential area. Figure 29 - Outfall 16-660 (2018) This outfall tested positive for detergent (0.55 mg/L) in 2017, so it was rescreened in 2018. Because the outfall was partially submerged, it was screened at the upstream manhole (16-660 US1) located approximately 257 feet upstream of the outfall, at the end of Fall Creek Lane. January 25, 2019 37 2018 Ongoing Screening Summary Report City of Oshkosh Figure 30 – Upstream manhole 16-660 US1 (2018) Detergent was detected in the 10/25/2018 sample, as well as the 10/26/2018 follow-up sample. Preliminary tracking activities were conducted on 10/29/2018. (The area received 0.2 inches of rain the previous day, which may have impacted the results.) No detergent was detected on this day, but the source of the flow in the manhole was investigated. The flow appeared to originate between manholes 16-1227 and 16-1230, near 335 Sunnybrook Drive. However, this does not indicate that this is the source of the detergent. The samples collected from the upstream manhole during prior screenings are summarized in Table 13: Table 13 - Sample results from outfall 16-660 Date Location Ammonia (ppm) Detergent (mg/L) pH Conductivity (µS/cm) 5/30/2012 Manhole 0 0 8.35 1,148 10/3/2017 Manhole 0 0.55 8.26 845 10/17/2017 Manhole 0 0 7.78 926 10/25/2018 Manhole 0 0.35 7.90 1,037 10/26/2018 Manhole 0 0.70 7.83 1,063 10/29/2018 Manhole 0 0 N/A N/A If the source of the detergent was “individual residential car washing,” the MS4 permit does not consider this an illicit discharge. However, because the exact source of the detergent was not identified, it cannot be considered exempt at this time. Because this outfall is a non-priority non-major outfall, it would normally be scheduled to be screened in 10 years. However, because of the potential illicit discharge, it will be scheduled to be rescreened in 2019. Additional information related to the investigation of this outfall is contained in Appendix D. Outfall 16-844 (N. Koeller Street) Outfall 16-844 consists of an 18-inch RCP that discharges into Sawyer Creek on the south side of N. Koeller Street. The drainage basin for the storm sewer is primarily a commercial area along Koeller Street, between Witzel Avenue and Sawyer Creek, just west of the former Kmart building. January 25, 2019 38 2018 Ongoing Screening Summary Report City of Oshkosh Figure 31 - Outfall 16-844 (2018) Detergent and elevated conductivity was detected in the 10/25/2018 sample, as well as the 10/26/2018 follow-up sample. Preliminary tracking activities were conducted on 10/29/2018. (The area received 0.2 inches of rain the previous day, which may have impacted the results.) Detergent was detected in the outfall flow, as well as from a manhole pool immediately upstream (west) of Taft Avenue. The remaining manholes were wet, but no samples could be collected. The samples collected from the outfall during prior screenings are summarized in Table 14: Table 14 - Sample results from outfall 16-660 Date Location Ammonia (ppm) Detergent (mg/L) pH Conductivity (µS/cm) 6/6/2012 Outfall 0 0 8.10 5,050 9/28/2015 Outfall N/A N/A N/A N/A 10/18/2016 Outfall 0 0 8.29 3,880 10/17/2017 Outfall 0 0 8.35 1,704 10/25/2018 Outfall 0 0.45 8.22 3,300 10/26/2018 Outfall 0 0.5 8.19 3,550 10/29/2018 Outfall 0 0.65 N/A N/A Because this outfall is classified as a priority outfall, it is scheduled to be rescreened in 2019.

Outfall 16-995 (Patriot Lane) Outfall 16-660 consists of a 30-inch high density polyethylene (HDPE) pipe that discharges into a low area at the end of Patriot Lane. The drainage basin for the storm sewer is primarily a residential area. January 25, 2019 39 2018 Ongoing Screening Summary Report City of Oshkosh Figure 32 - Outfall 16-995 (2018) This outfall tested positive for detergent (1.3 mg/L) in 2017, so it was rescreened in 2018. Because the outfall was partially submerged, it was screened at the upstream manhole (16-995 US1) located approximately 112 feet upstream of the outfall, in the sidewalk at the end of Patriot Lane. Figure 33 – Upstream manhole 16-995 US1 (2018) Detergent was detected in the 10/25/2018 sample, as well as the 10/26/2018 follow-up sample. Preliminary tracking activities were conducted on 10/29/2018. (The area received 0.2 inches of rain the previous day, which may have impacted the results.) The sample from the upstream manhole had detergent. The next upstream manhole (16-997) was dry. Therefore, no source of flow or detergent was identified.

Outfall 16-1205 (Westowne Avenue) Outfall 16-1205 consists of a 15-inch RCP that discharges the flow from one curb inlet on Westowne Avenue into the detention basin adjacent to the Shell gas station and McDonalds. Figure 34 - Outfall 16-1205 (2018) Because the outfall was partially submerged, it was screened at the upstream manhole (16-1205 US1) located approximately 36 feet upstream of the outfall, in Westowne Ave. January 25, 2019 41 2018 Ongoing Screening Summary Report City of Oshkosh Figure 35 – Upstream manhole 16-1205 US1 (2018) Detergent was detected in the 10/25/2018 sample, as well as the 10/26/2018 follow-up sample. The pool in the curb inlet was below the invert of the outfall pipe, so the sample was collected from the sump. Because the curb inlet is the only storm sewer component in the drainage basin, no additional tracking was possible. The samples collected from the upstream manhole during prior screenings are summarized in Table 16: Table 16 - Sample results from outfall 16-1205 Date Location Ammonia (ppm) Detergent (mg/L) pH Conductivity (µS/cm) 6/21/2012 Upstream N/A N/A N/A N/A 9/28/2015 Upstream N/A N/A N/A N/A 10/18/2016 Upstream N/A N/A N/A N/A 10/3/2017 Upstream N/A N/A N/A N/A 10/25/2018 Upstream 0 0.55 7.68 661 10/26/2018 Upstream 0 0.5 7.42 74 In past years, if the sump level was below the level of the outfall pipe, no sample was collected. Because this outfall is classified as a priority outfall, it is scheduled to be rescreened in 2019. Additional information related to the investigation of this outfall is contained in Appendix D. STATUS OF PRIOR YEAR’S ISSUES During the 2017 ongoing screening program, 101 outfalls were screened. The screening revealed 25 potential illicit discharges. 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 17 summarizes the issues that were identified in 2017, along with the conditions that were observed during the 2018 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 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. Damage Four outfalls showed signs of damage that may require attention in the near future. Observed damage included damaged ends of pipes and joint displacement between pipe sections and aprons. The outfall damage that was observed during the ongoing screening program is summarized in Table 18. January 25, 2019 45 2018 Ongoing Screening Summary Report City of Oshkosh Table 18 – Outfalls with damage Outfall Severity Description 06-478 Minor Minor (< 1”) joint displacement inside pipe 13-1109 Minor End of PVC pipe damaged 13-2872a Minor 3” joint displacement between pipe and apron 14-999 Moderate 4” joint displacement between last pipe sections 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.

Most of the outfalls with minor erosion could be repaired with minor landscaping repairs. Those outfalls January 25, 2019 48 2018 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 20.

The locations of the outfalls with erosion are shown on the map in Appendix C. Figure 49 – Bank erosion downstream of outfall 13-471 Graffiti Graffiti was observed in or around one outfall. 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 21.

All of the outfalls that had been identified as priority outfalls had been screened, along with a subset of the non-priority outfalls. After reviewing the potential illicit discharge history of the screened outfalls, OMNNI is recommending several changes to the outfall classifications. Due to no evidence of recent illicit discharges, the following 16 outfalls are proposed to be changed from Priority status to Non-Priority (major or non-major) status: • 01-20 • 01-35 • 01-278 • +03-119 • 08-937 • 09-101a • 12-576 • 12-1313 • 13-1098 • 13-1588 • 14-1514 • 15-143 • 15-146 • 15-1108 • 15-2409 • 15-2477 Due to consistent recent indications of potential illicit discharges, the following 2 outfalls are proposed to be changed to Priority status from Non-Priority (major or non-major) status: • 05-14 January 25, 2019 50 2018 Ongoing Screening Summary Report City of Oshkosh • 06-221 In addition, due to new configurations of storm sewer in certain areas, the following outfalls no longer exist, and will be removed from the MS4 inventory: • 12-2064 • 13-875 Based on the field observations, the overall outfall classification was revised to: • 31 priority outfalls • 81 non-priority major outfalls • 314 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 2019 outfall screening program: • 31 priority outfalls • 16 non-priority major outfalls • 31 non-priority non-major outfalls In addition, the 13 non-priority outfalls that had potential or obvious illicit discharges will also be rescreened, bringing the 2019 total to 91 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 2018 ongoing screening of the MS4 outfalls, as required by the MS4 permit. A total of 91 outfalls were screened, along with upstream monitoring locations when necessary. Of those 91 outfalls, 56 exhibited unlikely potential of past illicit discharges, and 35 were classified as “potential.” These results are summarized in Figure 51: January 25, 2019 51 2018 Ongoing Screening Summary Report City of Oshkosh Figure 51 – 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 23 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 2019 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 12-1328a to remove any remaining residue that may be contributing to the elevated pH in the discharge. 3. Investigate the presence of suds in manhole 13-2332 (Armory Pond) and identify which storm sewer lines are active or abandoned. 4. Televise the segment of storm sewer on Sunnybrook Drive between manholes 16-1227 and 16-1230, to determine the source of dry-weather flow. The ongoing screening also identified 4 outfalls with structural damage, 9 with deposition, one with erosion, and one 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 January 25, 2019 52 2018 Ongoing Screening Summary Report City of Oshkosh 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. The scope of this report is limited to the specific project and the inspection locations described herein. Prepared By: Jason Weis, P.E. Project Engineer Reviewed By: Brian D. Wayner, P.E.
