To maintain compliance with their Wisconsin Pollutant Discharge Elimination System (WPDES) permit, 87 outfalls within the City’s jurisdiction were screened. Of the screened outfalls, 31 were major outfalls, 34 were minor outfalls, and 22 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 C. 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 2023 Ongoing Field Screening Program are as follows. • 87 of 458 MS4 outfalls (19%) were screened, plus 49 upstream/alternate locations. • 74 outfalls were characterized as unlikely to have an illicit discharge. • 13 outfalls were characterized as a potential illicit discharge. • No outfalls were characterized as an obvious (confirmed) illicit discharge. • No confirmed illicit discharges were eliminated. The above results reflect the results of the routine outfall screening. Any actions resulting from complaints received by the City will need to be addressed in the corresponding sections of the MS4 Annual Report. 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 2023 Ongoing Field Screening Program, the City’s outfall inventory has been revised and consists of the following: January 24, 2024 2 2023 Ongoing Screening Summary Report City of Oshkosh Major/Minor Classification No. of Outfalls Prioritization Classification No. of Outfalls Major Outfalls 97 Priority Outfalls 39 Minor Outfalls 248 Non-Priority Major Outfalls 84 Supplemental Outfalls 113 Non-Priority Non-Major Outfalls 335 Total 458 Total 458 ILLICIT DISCHARGE AND FLOW OBSERVATIONS Of the 87 outfalls that were screened in 2023, 13 outfalls had physical or chemical indicators suggesting a potential or obvious illicit discharge.

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: • Nine of the 13 outfalls with potential 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. All of the outfalls with floating gross solids were already classified as Priority Outfalls, so they are already scheduled to be rescreened in 2024. • Outfall 03-173 (E. 16th Ave / Blended Waxes) consists of a 33x49” reinforced concrete pipe (RCP) that discharges to Lake Winnebago from the end of 16th Avenue. The outfall is fully submerged, and typically cannot be located. The first upstream manhole is located on the shoreline, approximately 18 feet upstream from the end of the pipe. When the outfall and manhole were screened on 7/17/2023, there was a dense mat of algae floating in the manhole. The sample collected from the manhole pool had an ammonia concentration greater than 6 ppm. The algae may have been a contributing factor to the elevated ammonia. Additional investigation, including additional upstream manhole sampling on the Blended Waxes property and the intersection of S. Main Street and E. 16th Avenue, was conducted with City assistance on 8/10/2023. None of the samples collected that day contained ammonia or any other indicators above action levels. January 24, 2024 4 2023 Ongoing Screening Summary Report City of Oshkosh The outfall was already classified as a Priority Outfall, so it is already scheduled to be rescreened in 2024. • Outfall 14-996 (Hughes Street / Oshkosh Corp test track) consists of a 48” RCP that discharges to a stream inside the secured Oshkosh Corporation test track. As a result of the limited access, the outfall is typically screened at the first upstream manhole, which is a curb inlet on the east side of Hughes Street. During the 7/19/2023 screening, a sample collected from the submerged pool in the curb inlet contained 3 ppm ammonia. Three pipes entered the manhole – smaller storm sewer pipes from the northeast and southwest, and a culvert from the Wittman Regional Airport on the west side of the road. All incoming pipes were dry, so no additional tracking could be conducted. There have been no prior potential illicit discharges noted at this outfall. Because this outfall is not currently listed as a Priority Outfall, it would not normally be screened in 2024. However, due to the ammonia results, it will be added to the 2024 screening list. • Outfall 15-3373 (Comet Street) consists of a 27” RCP that discharges to the south side of a detention basin located north of Comet Street. This outfall was rescreened in 2023 due to a 0.25 mg/L detergent detection in 2022. During the 7/17/2023 screening, the outfall was partially submerged, so a sample was collected from the submerged pool in the first upstream location (curb inlet). This sample had a detergent concentration of 0.9 mg/L. The next upstream location (another curb inlet) was dry, so no additional tracking could be conducted. Additional sampling was conducted on 7/19/2023, and pool samples from Comet Street and Geneva Street (both discharging to the same detention basin) both had similar detergent levels, with no incoming flows. It could not be determined if both streets had experienced similar detergent discharges in the past, or if stormwater from the detention basin had backed up into the pipes prior to receding. No conclusive source was identified. Because this outfall is not currently listed as a Priority Outfall, it would not normally be screened in 2024. However, due to the detergent results, it will be added to the 2024 screening list. • 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. This outfall has historically had elevated conductivity and/or detergent detections; however, repeated upstream tracking has never produced a conclusive source of the flow. During the 8/1/2023 screening, a sample collected from the outfall had a conductivity of 7,200 µS/cm, which exceeds the 2,000 µS/cm action level. Due to the history at the outfall, no additional tracking was conducted in 2023. 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 2024. With the exception of outfalls 14-996 and 15-3373, all outfalls with potential illicit discharges were already classified as Priority Outfalls, so they will automatically be rescreened in 2024. The January 24, 2024 5 2023 Ongoing Screening Summary Report City of Oshkosh two previously listed non-priority outfalls will also be added to the 2024 inspection list. Additional upstream and/or downstream screening and sampling may be conducted in 2024 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 B, along with relevant correspondence with the City. NON-ILLICIT DISCHARGE OBSERVATIONS The ongoing screening identified eight outfalls with some degree of visible damage, 22 outfalls with deposition, two with downstream erosion, and two with nearby 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 D 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 2023 screening year will be rescreened in 2024, regardless of their priority status. With the exception of outfalls 14-996 and 15-3373, all outfalls that were identified as “potential” or “obvious” illicit discharges in 2023 were priority outfalls, which would already be included in the 2024 screening. The two additional non-priority outfalls have been added to the 2024 screening schedule. Based on the latest revisions, the proposed 2024 screening schedule includes 92 outfalls: • 39 Priority outfalls • 18 Non-priority major outfalls (including 14-996 rescreening) • 35 Non-priority non-major outfalls (including 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.

I collected samples from the shoreline manhole, the manhole inside Blended Waxes’ fenced area, and the intersections of 16th and Main, Doty and Nebraska. None of the samples contained ammonia or detergent. The algae mat had been removed from the shoreline manhole. Based on these findings, it appears that the elevated ammonia in the manhole sample was likely from the accumulation of decaying algae, and not an upstream illicit discharge. This outfall is already classified as a Priority Outfall, so it will be automatically screened in 2024. If ammonia or other indicators are detected at that time, additional tracking could be completed. This concludes the screening of the MS4 outfalls scheduled for 2023. I will generate outfall reports and a summary report later in the year. If you have any questions, please let me know.

If we get rain overnight, we’ll have to postpone until next week. But for now, let’s plan on tomorrow. It’s probably best to do it when traffic is lighter. You probably have a better feel for local traffic patterns, so I’m open for suggestions. Maybe 10:00, between the morning and lunch rushes? Also, can someone from the City contact Blended Waxes and have the gate open to provide access to the manhole in their fenced yard at the time of inspection (or come along to assist)? Sometimes businesses are less than cooperative during investigations. Let me know a good time, and I’ll arrive 20 minutes early to check the shoreline manhole and positively ID the manhole(s) in the street. If Oshkosh gets rain before that, please let me know.

If we grab new samples from US1 (shoreline), US2 (fenced area of Blended Waxes), US3 (Main Street) and US4 (Doty Street), we should have a fairly complete data set. In the meantime, it might be helpful to try to remove as much of the algae mat from the US1 manhole as possible, to eliminate that as a possible source.

Only open links and attachments from known senders. DO NOT provide your username or password to anyone. After two days of screening (7/17 and 7/19), 57 of the 89 outfalls have been screened. Most of the remaining outfalls are along Campbell Creek and near the County Community Park. Here is a follow-up to some of the issues: Outfall 15-3373 (Comet St) detergent I collected additional samples at the Comet St outfall (15-3373), the Geneva Street outfall (15-3372) and upstream curb inlet, and the Jackson Street outfall (15-3329). The water in the detention basin was fairly shallow, and the pools around the outfalls were not really interconnected. Most of the flow entering and leaving the pond appeared to be coming from the Jackson Street outfall – the Geneva and Comet Street outfalls seemed to have isolated pools of water. There was no detergent detected in the Jackson Street outfall sample. The Comet Street sample once again had detergent (0.8 mg/L at the outfall pool). Similar to on 7/17, the first upstream curb inlet had pooled water, but the second upstream curb inlets were dry. 8 The Geneva Street outfall also had detergent – 1.2 mg/L at the outfall pool, and 1.0 mg/L in the pool in the first upstream curb inlet. Similar to Comet Street, the next upstream curb inlet was dry, so no additional tracking or sampling was conducted. It is unknown if there are intermittent detergent discharges on both streets that are collecting in their respective outfall pools, or if a discharge from one street is collecting in the detention basin and backing up into the other street. With no active flow, it is difficult to identify the source(s). Unless directed otherwise by the City, we will not conduct additional investigation on this discharge, but will add both outfalls to the 2024 inspection list. Outfall 03-173 (Blended Waxes) As mentioned previously, the outfall was fully submerged, so the initial sample was collected from the first upstream manhole, which is located on the shoreline between the railroad tracks and the water. The manhole had several inches of algae in it, which was decomposing. The ammonia in the manhole sample was over 6 ppm (the upper limit of the test strips). The next upstream manhole was located in the locked security fence behind Blended Waxes. The next upstream manhole was located in the middle of Main Street, and was inaccessible due to heavy traffic. A sample was collected from the next manhole at the intersection of W 16TH St and Doty St. No ammonia was detected in this sample. Based on the upstream sampling, it appears reasonable to assume that the elevated ammonia in the original sample was due to the decomposing algae, and not from an upstream illicit discharge. No additional investigation will be performed on this outfall, unless directed by the City. The outfall is already classified as a Priority Outfall, so it would be scheduled for reinspection in 2024. Outfall 14-996 (Oshkosh Truck test track / Hughes Street) Outfall 14-996 discharges to a stream inside the Oshkosh Truck test track on the southeast side of Hughes Street. It is surrounded by a security fence and inaccessible. There were several vehicles on the track during the screening. The outfall was screened at the upstream curb inlet on Hughes Street. The sample collected from the submerged pool in the catchbasin had an ammonia concentration of 3 ppm, so additional upstream tracking was conducted. Smaller pipes entered the catchbasin from the NE and SW, and both pipes entered above the pool and were dry. The other pipe entering the catchbasin from the NW was daylighted on the airport side of the street. This upstream pipe end was dry, and no flow was observed inside the pipe from that end. The outfall pipe from the airport was immediately upstream of this pipe, and was also dry. Due to the lack of any incoming flow, it was assumed that the pooled water in the pipe was backed up from the receiving water at the outfall. No additional tracking was able to be conducted. Screening has been suspended during EAA AirVenture, due to the increased traffic. We hope to wrap things up in early August. If you have any questions, please let me know.

During yesterday’s screening, the ou all was par ally submerged, so a sample was collected from the next upstream loca on, which was a curb inlet in the Comet St cul-de-sac. The curb inlet also had a submerged pool, and the sample from the pool had a detergent concentra on around 0.9 mg/L. All other IDDE parameters were within normal limits. Because of the previous detergent history at this manhole, I checked the next upstream loca on – the curb inlets just south of the sampled inlet. These inlets were dry, so no addi onal samples could be collected, and no addi onal tracking could be conducted. Because this submerged pool sample could essen ally be backed up water from the deten on basin, iden fying a source will be diﬃcult. When I am doing the next screening (tenta vely Wednesday), I will collect addi onal samples from the deten on basin, as well as the other two ou alls discharging to the basin (15-3372 – Geneva St and 15-3329 – Jackson St) to see how widespread the detergent is. Assuming no ac ve ﬂow is encountered, I will document the results of the sampling as proof of our follow-up. Iden fying a source when dealing with only pooled water (no ac ve ﬂow) is almost impossible. If you have any ques ons – or sugges ons for addi onal inves ga on – please let me know. I was able to screen 26 ou alls on Monday, and the only other ou all with a poten al issue was 03-173 (Blended Waxes). The upstream manhole that is located immediately adjacent to the shoreline had several inches of decaying algae at the top of the submerged pool. The ammonia concentra on of the pool sample was > 6 ppm, likely as a result of the decaying algae. I will take an addi onal sample upstream of Main Street, outside of the reach of the algae, to verify that there is not an ammonia source coming from upstream.

This information can be passed along to the appropriate personnel for any necessary action. Damage Eight 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 06-2798 Minor Apron undercut 4” 06-1136 Minor 3” joint displacement 06-478 Minor 3” joint displacement/deterioration 13-2332 Minor 2” joint displacement 13-3774 Minor 2” joint displacement 14-999 Minor 3” joint displacement, downed trees at end of pipe 15-3339 Minor Debris (log) on apron 16-2092 Minor 3” joint displacement The outfall damage is shown in the photos that follow. The locations of the damaged outfalls are shown on the map in Appendix D.

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.

Most outfalls with minor erosion could be repaired with minor landscaping repairs. Those outfalls 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 3. Table 3 – Outfalls with erosion Outfall Severity Description 13-471 Moderate Downstream channel erosion 13-2332 Moderate Downstream channel erosion The outfall erosion is shown in the photo that follows. The location of the outfall with erosion is shown on the map in Appendix D. Figure 31 – Channel erosion downstream of outfall 13-471 Figure 32 – Channel erosion downstream of outfall 13-2332 Graffiti Graffiti was observed in or around two outfalls. The graffiti was not severe but should probably be monitored to make sure that it does not become more severe. The graffiti that was observed during the ongoing screening program is summarized in Table 4.
