(Westwood) assisted the City of Oshkosh with screening the outfalls in the City’s municipal separate storm sewer system (MS4) for potential illicit discharges. To maintain compliance with their Wisconsin Pollutant Discharge Elimination System (WPDES) permit, 96 outfalls within the City’s jurisdiction were screened. Of the screened outfalls, 33 were major outfalls, 38 were minor outfalls, and 25 were supplemental outfalls. A map and list of the screened outfalls are included in Appendix A. The individual outfall field screening reports for the screened outfalls are contained in Appendix B. For a description of the City’s Illicit Discharge Field Screening Program, please refer to the Ongoing Field Screening Program – 2021 Update (March 2, 2021). The 2021 program contains a comprehensive description of the program, maps depicting the City’s outfalls, and information on how the program complies with the City’s WPDES permit from the Wisconsin Department of Natural Resources (WDNR). SUMMARY OF ILLICIT DISCHARGE PROGRAM’S MEASURABLE GOALS Results for the City’s 2022 Outfall Field Screening Program are as follows. • 96 MS4 outfalls were screened. • 75 outfalls were characterized as unlikely to have an illicit discharge. • 21 outfalls were characterized as a potential or obvious illicit discharge. • No educational materials were distributed to the public during the screening, as screening personnel did not encounter members of the public during the screening. OUTFALL INVENTORY As part of the Ongoing Field Screening Program, the City’s inventory of MS4 outfalls is reviewed annually and updated to reflect changes to the MS4, including new development, installation of stormwater management facilities, or street reconstruction. Prior to conducting the scheduled outfall screening, the City’s updated storm sewer mapping is reviewed to identify new, removed, or modified outfalls, and the screening schedule is updated accordingly. Similarly, if differences are identified during the screening process, those changes are made as they are encountered. For each new or modified outfall, a determination is made as to its major/minor status, as well as its priority outfall status. Following the completion of the 2022 Ongoing Field Screening Program, the City’s outfall inventory has been revised and consists of the following: Major/Minor Classification No. of Outfalls Prioritization Classification No. of Outfalls Major Outfalls 97 Priority Outfalls 39 Minor Outfalls 247 Non-Priority Major Outfalls 84 Supplemental Outfalls 113 Non-Priority Non-Major Outfalls 334 Total 457 Total 457 December 6, 2022 2 2022 Ongoing Screening Summary Report City of Oshkosh Appendix A includes a list of outfall modifications, along with the calculations for determining major/minor status and priority outfall status. The updated outfall screening schedules are also included in Appendix A. ILLICIT DISCHARGE AND FLOW OBSERVATIONS Of the 96 outfalls that were screened in 2022, 21 outfalls had physical or chemical indicators suggesting a potential or obvious illicit discharge. Those outfalls are summarized in the table below: Outfall Date Flow pH Conductivity (µS/cm) Ammonia (ppm) Total Chlorine (ppm) Free Chlorine (ppm) Detergent (mg/L) Gross Solids Illicit Discharge Potential 02-357 9/23/2022 Submerged (not located) X Potential 02-357 US1 9/23/2022 Submerged, indeterminate 7.80 570 0 0 0 0 X Potential 03-119 8/22/2022 Submerged (not located) Potential 03-119 US1 8/22/2022 Submerged, indeterminate 6.89 312 0 0 0 0.2 Potential 03-173 8/22/2022 Submerged (not located) X Potential 03-173 US1 8/22/2022 Submerged, indeterminate 8.80 450 0 0 0 0 X Potential 03-22 8/24/2022 Submerged (not located) X Potential 03-22 US1 8/24/2022 Submerged, indeterminate 8.54 395 0 0 0 0 X Potential 03-35 8/24/2022 Submerged (not located) X Potential 03-35 US1 8/24/2022 Submerged, indeterminate 8.10 593 0 0 0 0 X Potential 03-604 8/22/2022 Submerged (not located) Potential 03-604 US1 8/22/2022 Submerged, indeterminate 8.67 428 1 0 0 0 Potential 03-81 8/22/2022 Submerged (not located) X Potential 03-81 US1 8/22/2022 Submerged, indeterminate 8.43 345 0 0 0 0 X Potential 06-3027 8/23/2022 Submerged, slight flow 8.12 433 0 0 0 1 Potential 06-52 8/24/2022 Submerged (not located) X Potential 06-52 US1 8/24/2022 Submerged, indeterminate 6.67 374 0 0 0 0 X Potential December 6, 2022 3 2022 Ongoing Screening Summary Report City of Oshkosh Outfall Date Flow pH Conductivity (µS/cm) Ammonia (ppm) Total Chlorine (ppm) Free Chlorine (ppm) Detergent (mg/L) Gross Solids Illicit Discharge Potential 08-284 9/16/2022 Submerged (not located) X Potential 08-284 US1 9/16/2022 Submerged, indeterminate 7.24 364 0 0 0 0 X Potential 08-347 9/16/2022 Submerged (not located) Potential 08-347 US1 9/16/2022 Submerged, indeterminate 7.51 922 0 0 0 0.4 Potential 11-376 9/23/2022 Submerged (not located) X Potential 11-376 US1 9/23/2022 Submerged, indeterminate 7.16 648 0.25 0 0 0 X Potential 11-512 9/23/2022 Submerged (not located) X Potential 11-512 US1 9/23/2022 Submerged, indeterminate 7.84 460 0 0 0 0 X Potential 13-1098 8/18/2022 Submerged, slight flow 7.15 1,805 3 0 0 0 Obvious 13-471 8/22/2022 Submerged, slight flow 7.78 476 0.25 0 0 0.3 Potential 15-3339 9/30/2022 Submerged, indeterminate Potential 15-3339 US1 9/30/2022 Submerged, indeterminate 7.52 1,428 0 0 0 -1 Potential 15-3373 9/30/2022 Submerged, slight flow 7.55 841 0 0 0 0.25 Potential 16-1205 8/23/2022 Submerged, no flow 8.55 835 0 0 0 2.5 Potential 16-594 8/24/2022 Submerged (not located) X Potential 16-594 US1 8/24/2022 Submerged, indeterminate 8.12 336 0 0 0 0 X Potential 16-844 9/16/2022 Trickle 7.99 2,310 0 0 0 0 Potential 16-995 8/23/2022 Submerged, no flow 7.46 325 0 0 0 3.5 Potential Bold entries indicate test results that exceed the action limit for the chemical. Italic entries indicate alternate sampling locations for an outfall. Shaded outfalls indicate outfalls with significant floatable gross solids. The outfalls with potential or obvious illicit discharges are summarized below: • Ten of the 21 outfalls with potential or obvious illicit discharges were classified as “Potential” solely due to the presence of moderate or substantial floatable debris (gross solids), including plastic bottles, foam packaging, and other solid waste. 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 it is not able to escape through the submerged outfall pipe. December 6, 2022 4 2022 Ongoing Screening Summary Report City of Oshkosh All of the outfalls with floating gross solids were already classified as Priority Outfalls, so they are already scheduled to be rescreened in 2023. • Outfall 03-119 (Pioneer Marina) consists of a 13x22” reinforced concrete pipe (RCP) that discharges from the south side of the boat launch at Pioneer Marina. The outfall is typically fully submerged and not located, so it is screened at the first accessible upstream manhole in Pioneer Drive. During the 8/22/2022 screening, the sample from the upstream manhole had a detergent concentration of 0.2 mg/L. A follow-up screening on 8/31/2022 resulted in a detergent concentration of 0.8 mg/L at the first upstream manhole, and no detergent at the next upstream manhole near the railroad tracks. Another follow-up screening on 9/28/2022 resulted in no detergent detections in any upstream manholes, so no additional tracking could be conducted. The outfall was already classified as a Priority Outfall, so it is already scheduled to be rescreened in 2023. • Outfall 03-604 (E 14th Avenue) consists of a 60x96” elliptical RCP that discharges to Lake Winnebago. During the 8/22/2022 screening, the pipe was fully submerged and not located, so the screening was conducted at the first upstream manhole. The sample collected from the submerged pool in the manhole had an ammonia concentration of 1 ppm, which is at the action limit for ammonia. On 8/31/2022, the manhole and additional upstream manholes along 14th Avenue up to the Main Street intersection were rescreened. The ammonia concentrations in the manholes ranged from 0.25 to 1.0 ppm. No definitive source was identified due to the extent of the submerged condition. Because this outfall is not currently listed as a Priority Outfall, it would not normally be screened in 2023. However, due to the ammonia detection, it will be added to the 2023 screening list to determine if the ammonia is still present. • Outfall 06-3027 (W 9th Avenue) consists of a 43x68” RCP that discharges to the stream from the west, north of 9th Avenue. During the 8/23/2022 screening, a sample was collected from the submerged flow in the pipe. The sample had a detergent concentration of 1 mg/L. The outfall was rescreened on 8/31/2022 along with two additional upstream manholes. Samples collected during that date showed no detergent, so no additional upstream tracking could be conducted. Because this outfall is not currently listed as a Priority Outfall, it would not normally be screened in 2023. However, due to the ammonia detection, it will be added to the 2023 screening list to determine if the ammonia is still present. • Outfall 08-347 (Broad Street) consists of a 42” corrugated metal pipe (CMP) that discharges to the north side of the Fox River, immediately east of the railroad bridge. The outfall is fully submerged and has not been physically located. As a result, it is screened at the first upstream manhole, which is located in the railroad right-of-way. During the 9/16/2022 screening, the sample collected from the upstream manhole had a detergent concentration of 0.4 mg/L. This manhole has frequently contained floating gross solids but has not had chemical indicators in the past. A rescreening was conducted on 9/19/2022, and no detergent was detected in the manhole, so no additional tracking could be conducted. December 6, 2022 5 2022 Ongoing Screening Summary Report City of Oshkosh The outfall is classified as a Priority Outfall, primarily due to the floating gross solids that frequently appear in the upstream manhole. As a result, the outfall is already scheduled to be rescreened in 2023. • Outfall 13-1098 (Universal Street / Amcor) consists of a 24” RCP that discharges to a stream on the east side of Universal Street. The majority of the contributing storm sewer comes from the Amcor Flexibles Specialty Films plant. During the 8/18/2022 screening, the sample collected from the submerged outfall flow had an ammonia concentration of 3 ppm and a fairly strong sewer odor. The findings were reported to the City of Oshkosh, and the building inspection department worked with the plant to determine that a recent renovation caused a sanitary sewer cross connection. The plumbing issues were rectified at the plant and the storm sewer line was cleaned. A follow-up sample following the repair showed no residual ammonia or odor. The outfall is classified as a Priority Outfall, primarily due to the industrial drainage area. As a result, the outfall is already scheduled to be rescreened in 2023. • Outfall 13-471 (9th Avenue / Armory Place) consists of a 48x76” RCP that discharges to the north side of 9th Avenue, where it continues to flow north in an open channel. During the 8/22/2022 screening, a sample collected from the submerged flow in the outfall pipe contained 0.3 mg/L detergent and 0.25 ppm ammonia. This outfall has had detergent detections during the period of 2018-2021, which have been traced back to the Armory Pond. No other definitive source has been identified to this point. The outfall was rescreened on 8/31/2022, an no detergent or ammonia was present in the sample. The outfall is classified as a Priority Outfall, primarily due to the recurring detergent discharges. As a result, the outfall is already scheduled to be rescreened in 2023. • Outfall 15-3339 (N Main Street detention basin) consists of a 54” RCP that discharges to the northeast corner of the detention basin located near the southwest corner of Main Street and Packer Avenue. During the 9/30/2022 screening, the outfall was partially submerged, so a sample was collected from the first upstream location (15-3339 US1), which consists of a curb inlet on Main Street. The detergent test produced abnormal results – all of the blue dye was stripped from the sample, which then settled to the bottom. Westwood has observed this result one other time, which came from an outfall that was contaminated with firefighting foam. However, the Oshkosh Fire Department confirmed that no foam had been deployed in this area this year. The curb inlet and surrounding manholes were rescreened on 10/3/2022, and no detergent was detected, so no additional tracking could be completed. Because this outfall is not currently listed as a Priority Outfall, it would not normally be screened in 2023. However, due to the detergent results, it will be added to the 2023 screening list. • Outfall 15-7737 (Comet Street) consists of a 27” RCP that discharges to the south side of a detention basin located north of Comet Street. During the 9/30/2022 screening, a sample was collected from the submerged flow at the outfall. The sample had a detergent concentration of 0.25 mg/L. The outfall and several upstream manholes were December 6, 2022 6 2022 Ongoing Screening Summary Report City of Oshkosh rescreened on 10/3/2022, and no detergent was detected in any of the samples, so no additional tracking could be conducted. Because this outfall is not currently listed as a Priority Outfall, it would not normally be screened in 2023. However, due to the detergent results, it will be added to the 2023 screening list. • Outfall 16-1205 (N Washburn St) consists of a 15” RCP that discharges to the east side of the detention basin located at the northwest corner of Washburn Street and Westowne Avenue. Only one curb inlet on the west side of Washburn Street is connected to this outfall, and the water level in the curb inlet sump is usually below the invert elevation of the pipe. A sample collected from the outfall pool at the end of the pipe during the 8/23/2022 screening had a detergent concentration of 2.5 mg/L, which was assumed to be the concentration for the entire detention basin. During a follow-up screening, the inspector noticed that cars leaving the carwash near the west end of the detention basin were dripping into the nearby storm sewer, which also discharges to the detention basin. Based on this observation, along with the limited drainage basin for 16-1205, the detergent in the detention basin is more likely a result of the car wash than the curb inlet. Outfall 16-1205 is classified as a Priority Outfall, primarily due to recurring detergent detections in the detention basin. As a result, the outfall is already scheduled to be rescreened in 2023. Additional investigation will be conducted on the west side of the detention basin to determine if the carwash is the source of the detergent. • Outfall 16-844 (Koeller Street) consists of an 18” RCP that discharges to the south side of the stream, immediately east of the Koeller Street bridge. During the 9/16/2022 screening, a sample collected from the outfall had a conductivity of 2,310 µS/cm, which exceeds the 2,000 µS/cm action level. Samples were collected at several upstream locations along Koeller Street, and all had high conductivity values. No conclusive source or storm sewer segment was identified. Similar results have been observed in this outfall since 2012. The outfall is classified as a Priority Outfall, primarily due to the recurring high conductivity results and occasional detergent detections. As a result, the outfall is already scheduled to be rescreened in 2023. • Outfall 16-995 (Patriot Lane) consists of a 30” high density polyethylene (HDPE) pipe that discharges to a wooded swale at the east end of Patriot Lane. During the 8/23/2022 screening, a sample collected from the submerged pool at the outfall contained approximately 3.5 mg/L detergent. When the outfall was rescreened on 8/31/2022, the outfall pool had no detergent, the first upstream manhole had 0.7 mg/L detergent, and the next upstream manhole was dry. Due to the lack of flow, no additional tracking could be conducted. There have been occasional detergent detections at this outfall since 2017. The outfall is classified as a Priority Outfall, primarily due to the recurring detergent discharges. As a result, the outfall is already scheduled to be rescreened in 2023. December 6, 2022 7 2022 Ongoing Screening Summary Report City of Oshkosh With the exception of outfalls 03-604, 16-3027, 15-3339 and 15-3373, all outfalls with potential illicit discharges in 2022 were already classified as Priority Outfalls, so they will automatically be rescreened in 2023. The four previously listed non-priority outfalls will also be added to the 2023 inspection list. Additional upstream and/or downstream screening and sampling may be conducted in 2023 to attempt to isolate the potential source(s) of the discharges. Maps of the drainage areas for the outfalls with potential or obvious illicit discharges are included in Appendix D, along with relevant correspondence with the City. NON-ILLICIT DISCHARGE OBSERVATIONS The ongoing screening identified four outfalls with some degree of visible damage and seven outfalls with deposition. None of the outfalls screened in 2022 had reported erosion or graffiti. While none of these posed an immediate danger, the City will likely want to address these issues as part of the regular storm sewer system maintenance. Appendix C contains lists, maps, and photos of outfalls with non-illicit discharge concerns. FUTURE FIELD SCREENING The general screening schedule approach is outlined in the Ongoing Field Screening Program – 2021 Update. The outfalls within the City’s jurisdiction that are deemed “priority” are to be screened every year and the major outfalls that are deemed “non-priority” are to be screened every five years. Non-priority, non-major outfalls are to be screened every ten years. A preliminary screening schedule was developed as part of the Ongoing Field Screening Program. This screening schedule is updated each year as outfalls are added, removed, or reclassified. In addition, any non-priority outfalls with potential illicit discharges are scheduled for a repeat screening in the following year. Any outfalls listed as “potential” or “obvious” illicit discharges from the 2022 screening year will be rescreened in 2023, regardless of their priority status. With the exception of outfalls 03-604, 16-3027, 15-3339 and 15-3373, all outfalls that were identified as “potential” or “obvious” illicit discharges in 2022 were priority outfalls, which would already be included in the 2023 screening. The four additional non-priority outfalls have been added to the 2023 screening program. One priority outfall – 03-381 – was removed from the inventory due to reconstruction along Pioneer Drive. Once construction is complete, if the outfall is replaced, its classification will be determined based on the new storm sewer configuration and surrounding land use. Based on the latest revisions, the 2023 screening schedule includes 89 outfalls: • 39 Priority outfalls • 17 Non-priority major outfalls (including 03-604 and 06-3027 rescreening) • 33 Non-priority non-major outfalls (including 15-3339 and 15-3373 rescreening)) The updated screening schedule is included in Appendix A. The City of Oshkosh reserves the right to revise the screening schedule as long as the goals of the screening frequency are achieved.

Appendix C Outfall Condition Summary C-1 Outfalls with Damage C-2 Outfalls with Deposition C-3 Outfalls with Erosion C-4 Outfalls with Graffiti OUTFALL CONDITION ASSESSMENTS While not required for the illicit discharge field screening, Westwood inspectors noted the presence of any visual 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 pipe joint displacement, damaged pipes and aprons, and corrosion. The outfall damage that was observed during the ongoing screening program is summarized in Table 1. Table 1 – Outfalls with damage Outfall Severity Description 14-999 Minor Pipe joints displaced 3”. 15-787 Minor Surface corrosion on CMP. 16-2204 Minor Broken concrete at end of pipe. Wash41_01 US1 Minor Corrosion on flowline of CMP. The outfall damage is shown in the photos that follow. The locations of the damaged outfalls are shown on the map in Appendix C. Figure 1 – Outfall 14-999 Figure 2 – Outfall 15-787 Figure 3 – Outfall 16-2204 Figure 4 – Outfall Wash41_01 US1 Deposition Seven outfalls showed minor, moderate, or severe deposition at the end of the outfall pipe or channel, or inside the upstream screening location. 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 2. Table 2 – Outfalls with deposition Outfall Severity Description 06-2804 Minor 2” of sediment in pipe and on apron 06-1601 Minor 5” of sediment in pipe and on apron 06-1633 Minor 2” of sediment in pipe 13-1098 Moderate 18” of sediment in pipe 14-2024 Minor 3” of sediment on one side of apron 14-999 Minor 3” of sediment in pipe 15-3373 Minor 1” of sediment in pipe The outfall deposition is shown in the photos that follow. The locations of the outfalls with deposition are shown on the map in Appendix C.

Only open links and attachments from known senders. DO NOT provide your username or password to anyone. Justin: I’m not sure if you’re the official illicit discharge contact person. If not, please forward this to the appropriate person, and let me know who to contact for future issues. Outfall 13-1098 is located at the Universal Street loading dock driveway for Amcor Flexibles (see map on attached outfall reports). The outfall consists of a 24” RCP that comes from inside the fenced-in yard at the plant. The pipe discharges to a small pond on the north side of the driveway, and eventually flows north. During today’s inspection, the outfall pipe was partially submerged with a slight flow. The inspector sampled this flow, which had an ammonia concentration of 3 ppm. (The IDDE action level for ammonia is 1 ppm.) He then sampled the next upstream location, which was the catchbasin on the south side of the driveway. A sample from this submerged pool had an ammonia concentration in excess of the capacity of the test strips (>6 ppm), and had a sewage smell. Because the next sampling location was on private property (inside the fence), our tracking was halted. Because of the high ammonia concentration and sewage odor, there is a possibility of a sanitary cross connection. I would recommend having a plumbing inspector or other authorized city personnel follow up with this discharge on the facility’s property. According to the WDNR municipal stormwater permit, if the source cannot be remedied within 30 days, a plan must be submitted to WDNR. Please let me know if you need additional information, or if you need assistance with tracking.

It consists solely of a curb inlet on the west side of Washburn Street. Therefore, the only potential for illicit discharge through this outfall is from runoff into the curb inlet. Because the outfall is typically partially submerged, a sample is collected from the pool in the curb inlet. Over the past few years, this sample has frequently contained detergent. Because of the nature of the drainage basin, the detergent is likely in the pond itself, rather than isolated to outfall 16-1205. During the 8/31 screening, the sample from the outfall had a detergent concentration of 0.7 mg/L. We conducted a follow-up screening on 9/28, and no detergent was detected in the outfall pool or the pond. However, the inspector noticed that the carwash west of the Shell station had several catchbasins at the exit of the carwash that appeared to be receiving runoff from the carwash. Because they were located outside the building, it is suspected that they connect to the storm sewer rather than the sanitary sewer. If this is the case, this may be a source of detergent in the pond (via outfall 16-1207, rather than 16-1205). If the City has site plans for this car wash, it may be worth checking if these catchbasins at the end of the carwash are indeed connected to the storm sewer and ultimately the detention basin. Outfall 16-995 (Patriot Lane) Outfall 16-995 is located at the east end of Patriot Lane. The outfall discharges to a wooded swale, and the roots and terrain have created a small dam at the end of the outfall pipe. Samples collected from this outfall pool have traditionally had varying concentrations of detergent. Upstream screening typically reveals a submerged pool in the first upstream manhole (at the end of the cul-de-sac), and occasionally the next upstream manhole. Other upstream manholes and curb inlets are typically dry. During the 8/31 screening, the upstream manhole had a detergent concentration of 0.9 mg/L. We conducted a follow- up screening on 9/28, and no detergent was detected in any of the manholes or outfall pool. Based on this and previous years’ experience, it appears that there may be a periodic discharge of detergent into the storm sewer, which becomes trapped in the submerged pool until it is flushed out by rainwater or sump pump discharges. Due to the residential nature of this drainage basin, the most likely sources are external washing of cars, boats, garbage cans, etc., or a basement cross connection (sink or washing machine into a sump pump). Because of the intermittent nature, this would be a difficult discharge to narrow down. One option would be to place cotton traps at each manhole during a dry period and check for evidence of discharge (and detergent) before the next rainfall event. Depending on how much the sump pumps run in this are during “dry” periods, the effectiveness of this will vary. Please let us know if you’d like us to attempt this tracking. Outfall 13-1098 (Universal Dr sanitary cross connection) Samples were collected from the outfall and upstream catchbasin to verify that there was no evidence of the past sanitary discharge following the plant’s repair of the cross connection. Both samples were clear of ammonia and detergent, so the connection appears to be repaired, and the illicit discharge case can be considered closed. Additional screening is being conducted today, and I anticipate one additional day to complete the rest of the outfalls on the 2022 list. Other than the potential illicit discharges listed above, the only other issue is the persistent floating gross solids in the manholes. As in previous years, the summary report will include a list of the impacted manholes. 2 If you have any questions about these outfalls or the program, please let me know.

Outfall maps for each outfall are attached. Outfall 15-3373 (Comet Street) The sample was collected from the submerged flow entering the detention basin. The sample had a detergent concentration of 0.25 mg/L. Our inspector is returning today to collect another sample from the outfall and the pond, and will also screen the upstream manholes and curb inlets on Comet Street, since the drainage basin for this outfall is fairly small. If we are able to better isolate the potential discharge, we will let you know. Outfall 15-3339 (Main Street / Packer Ave) The outfall at the NE corner of the detention basin was submerged, so a sample was collected from the first upstream location, which was a curb inlet on Main Street. The detergent test behaved strangely – all of the blue dye that was added to the sample was completely stripped by the chloroform, and the resulting solution was purple, rather than a shade of blue. I have only experienced this one other time, and that was from an outfall that recently had firefighting foam rinsed down it, and there was some residual in the manhole. Does the City have any records of foam deployment in this general area over the past few weeks? If so, that could explain the result. Otherwise, our inspector is going to collect samples this morning from the same location, as well as the pond and a few other upstream locations to attempt to isolate the discharge to a particular branch, to narrow down the tracking. We also need to take a closer look at the drainage divide between this outfall (15-3339) and the outfall on the NW corner (15-3337), to see if any of the Jackson St storm sewer discharges to 15-3339. We will let you know what today’s samples show, and if any additional follow-up is required. Please let me know if you have any questions.
