STRAND ASSOCIATES. INC.' ENGINEEf.18 D Information Only MEMORANDUM [gI Project Specific 2.944.002 D Policy Memo - File With TO: FROM: DATE: RE: Rob Waiz, Mayor and Jeffersonville Sewer Board Mark Sneve, P.E. ~ April 8, 2004 Review of EMC WWTP operations - February 2004 We have completed our monthly review of EMC's operations. The purpose of our review was to evaluate plant data and operation strategies to verify that EMC is operating the wastewater treatment plant in the best interest of the City of Jeffersonville. To c~mplete our review of the February operatip!l, we have reviewed the following: . Current contract between EMC and the City of Jeffersonville; E1v[C's DMR and MaR for February 2004 (received bye-mail 03/31/04 and 04/08/04). .. Strand Associates, Inc. discussed operating conditions with EMC during the month. Our review focused on EMC's monthly operation report (MaR). We have produced four pages of graphs from the monthly data provided (consistent with past monthly reviews). WWTP Loadings: The first page presents influent mass loadings and influent flows compared to design values. . Influent BOD loadings are averaging 121 % of the design loading (10,581Ibs/d). Two peak loadings of 25,383 and 29,284 and lbs/day were observed on February 2nd and 5th respectively. These peak- loading events coincided with rain events. There were no. yiolations of .~fflu~nt .limits as a result of these loadings. . The TSS loading averaged about 124% of design (10,105 lbs/d). Three peak loadings of 30,581, 25,885 and 22,826 lbs/day were observed on February 2nd, 3rd, and 5th respectively. These peak- loading events coincided with rain events. There were no violations of effluent limits as a result of these loadings. . The influent ammonia graph shows daily, 7-day, and 28-day moving average mass loadings. The NH3-N loading averaged 73% of the design loading (867 lbs/d). Peak loadings of 1511 and 857 lbs/day were observed on February 2nd and 5th respectively. There were no violations of effluent limits as a result of these loadings. . The influent flume data has been reported to IDEM as the plant flow since April 1, 2001. The peak flow capacity of the WWTP is 22.8 mgd and the peak sustained flow capacity is 16. The average flow during dry weather periods for the month of February was 5.2 mgd or 100% of the plant capacity (5.2-mgd). The average flow during the entire month of February was measured to be 6.28 \\PE:m..OUF01\VOLl ISDA T A \@PEH\901--950\944\002\WRD\Review ofEMC\Review of EMC Operations - February 2004 memo.doc i Review of EMC WWlP Operations - February 2004 Page 2 April 9, 2004 mgd or 121 % of the plant capacity (5.2-mgd). The peak daily flow reached 14.5 mgd on February 2nd, less than the "rated" capacity of 16 mgd. Rainfall in February was 1.85 inches, less than the typical February rainfall of 2.95 inches. Effluent Quality: The second page of graphs show the plant performance for effluent CBOD, TSS, and ammonia compared to the weekly average and monthly average effluent limits. The 7 -day moving average (MY A) effluent concentration is used to compare to the weekly permit limit and the 28-day moving average effluent limit is used to compare to the monthly average effluent limit. January is the second month of 'less stringent' winter effluent limits. The WWTP did not violate any conventional permit limits during February. · Effluent CBOD concentrations were below permit limits. · Effluent TSS concentrations were below the permit limits. · Effluent NH3-N concentrations were below the permit limits. Activated Sludge Process: The third page of graphs shows typical activated sludge parameters. . The first graph shows the food to mass of volatile organisms (F:Mv) ratio. For extended aeration activated sludge wastewater treatment plants, the target F:Mv is typically between 0.08 and 0.1. The activated sludge plant averaged 0.09 for February. The next graph shows the sludge volume index (SVI). SVI is an indicator of settleability of the mixed liquor. SVls below 159 are not cause for concern. SVI.above 150 suggests poor settling characteristics. SVI levels for the month of February averaged 202 and appear to be starting to decrease. This is on the high side and should be monitored closely. The high SVIs are characteristic of wintertime operation and does not appear to be the result of old sludge. EMC remains prepared to add polymer to their final clarifiers if necessary. The next graph shows the organic loading rate for the oxidation ditch activated sludge process. Your activated sludge process was designed with an OLR of 15-lb BOD/day/WOO cf. The 28-day running average OLR varied between 16.1 and 18 throughout the month. The high end is attributed to the high influent BOD following rain events. The average OLR was 18 lb BOD/day/WOO cf which is higher than usual due to the high loadings and flows noted. The next graph includes the solids loading rate (SLR), a measure of the mass of solids in the influent to the clarifiers. "Ten States Standards" limits the solids loading rate to less than 35 Ib/d/sf of clarifier surface area. The chart shows the daily, 7-day MV A and 28-day MV A SLR. The SLR has been averaging about 25-lb/d/sf with a daily peak of 27-lb/d/sf for the month of February. We have included a chart that shows the daily SVI and SLR data versus the curve from WEF MOP 8 and a curve specific to the Jeffersonville plant. This Jeffersonville curve was created by reviewing data from peak wet weather events over a three-year period as part of the CSOP update. Operation above this curve has resulted in effluent TSS violations. The chart demonstrates that the plant is generally operating below the "textbook" and Jeffersonville curves. The next plot is for mixed liquor suspended solids (MLSS in mgIL). The MLSS concentration of the activated sludge plant varied between 2,540 and 3,600 mgIL averaging about 3,270 mgIL. Typically MLSS ranges from 2,500 to 4,500 mg/L for the extended aeration process and these results fall ~ .. l. . . . . [lnitials]\\PEHLOUFOl \VOLl \SDA T A \@PEH\901--950\944\002\WRD\Review of EMC\Review of EMC Operations - February 2004 memo.doc\040904 sa. STRAND ASSOCIATES,INC." F-NGIN~6RS Review of EMC WWTP Operations - February 2004 Page 3 April 9, 2004 within this range. EMC no longer targets a MLSS concentration to control the process; they now target a constant sludge age. In the past, when the MLSS concentration dipped below 2,000 mg/L the nitrification process was affected. . The next graph shows the mixed liquor volatile suspended solids (ML VSS in mg/L) ML VSS has been varying between 1,600 mg/L and 2,500 mg/L with an average of 2,230 mg/L. This range is reasonable. The ML VSS shows the same trending as the MLSS graph. The historical minimum MLVSS to sustain complete nitrification appears to be 1,800 mg/L based on previous operational data. · The next graph shows the yield of solids from the activated sludge process. The yield is defined as the pounds of TSS produced per pound of BOD removed. For an extended aeration activated sludge plant, a yield between 0.8 and 1.1 is reasonable. YOllr plant had the 28-day moving average yield of 0.62, a lower number than typical. · The last graph shows the Sludge Age, a measure of the average time a microorganism spends in the activated sludge system. We recommended that the activated sludge process be operated to maintain a constant sludge age rather than a constant MLSS. The average sludge age during the month was 21 days with the targeted sludge age range of 20 to 22 days. In summary, the activated sludge process is performing well (BOD, TSS, and NH3-N removal). The average SVI levels began increasing in November. We recommend adding an anoxic zone preceding the oxidation ditch to improve the poor settleability of the sludge observed in early 2000, early 2001, late '2001, early 2002, early 2003 and'again.in late 2003. Such a tank could ,be added during a major reconstruction process, due to the need to disrupt process flow. In the interim, EMC may be able to operate aerators at low speed for times to create anoxic conditions; this should beinitiated with great caution as evidenced by the increasing effluent CBOD concentrations when attempted in mid-August 2000. The proposed anoxic one (or selector tank) is under design now.

April 8, 2004 Review of EMC WWTP operations - January 2004 We have completed our monthly review of EMC's operations. The following items summarize the attached memo: The WWTP received the following average flows and loadings during the month: o 118% of design BOD loading, o 105% of design TSS loading, o 77% of design ammonia loading, o 111% of design flow (dry weather data only) o 136% of design flow (all flow data). The WWTP did not have any permit violations during January. The activated sludge process is operating well. Settling is poor but manageable, consistent with past cold weather operation. No correlation between poor settling and higher sludge age is observed this year. All other process parameters are within acceptable ranges. Status of Current Projects: Plant ~ The effluent flow meter was replaced during the month. Pretreatment ~ Pretreatment staff met with Steel Dynamics during the month to discuss some pH meter problems they were experiencing. Lift stations and Collection System ~ EMC cleaned 4,285 feet of sanitary sewer and 7,205 feet of storm sewer. EMC also televise 1,367 feet sanitary sewer lines. All trouble spots were cleaned. ~ Nine mains were cleaned in EMCs preventive maintenance program. ~ EMC hand-cleaned 59 and vactor-cleaned 27 catch basins. ~ Nine lift stations were vactored and cleaned for grease buildup. ~ A pump was rebuilt along with electrical upgrades to the control panel at the Eastern Blvd PS. ~ A pump was rebuilt and all new floats were installed at the Louise Street station. ~ Maintenance was performed on backup generators, the tenth street station pump guide rails and the Spring Street lift station drive shaft guard. \\PEHLOUFOl\VOLl ISDATA\@PEH\90l--950\944\OO2\WRDIReview ofEMClReview ofEMC Operations - January 2004 exec sum.doc " sa.

GNGINEER8 o Information Only MEMORANDUM I:8J Project Specific 2.944.002 o Policy Memo - File With TO: FROM: DATE: RE: Rob Waiz, Mayor and Jeffersonville Sewer Board Mark Sneve, P.E.~ April 8, 2004 Review of EMC WWTP operations - January 2004 We have completed our monthly review of EMC's operations. The purpose of our review was to evaluate plant data and operation strategies to verify that EMC is operating the wastewater treatment plant in the best interest of the City of Jeffersonville. To complete our review of the January operation, we have reviewed the following: · Current contract between EMC and the City of Jeffersonville; · EMC's DMR and MaR for January 2004 (received bye-mail 03/08/04). Strand Associates, Inc. discussed operating conditions with EMC during the month. Our review focused on EMC's monthly operation report (MaR). We have produced four pages of graphs from the monthly data provided (consistent with past monthly reviews). WWTP Loadings: The first page presents influent mass loadings and influent flows compared to design values. · Influent BOD loadings are averaging 118% of the design loading (10,581 lbs/d). Three peak loadings of 30,073, 23,268 and 20,122 lbs/day were observed on January 4th, 5th and 17th respectively. These peak-loading events coincided with rain events. There were no violiations of effluent limits as a result of these loadings. . The TSS loading averaged about 105% of design (10,105 lbs/d). Three peak loadings of 19,080, 17,562 and 21,335 lbs/day were observed on January 4th, 16th and 26th respectively. These peak- loading events coincided with rain events. There were no violations of effluent limits as a result of these loadings. . The influent ammonia graph shows daily, 7-day, and 28-day moving average mass loadings. The NH3-N loading averaged 77% of the design loading (867 lbs/d). Peak loadings of 1053, 1005 and 1047 lbs/day were observed on January 17th, 18th and 26th respectively. There were no violations of effluent limits as a result of these loadings. . The influent flume data has been reported to IDEM as the plant flow since April 1, 2001. The peak flow capacity of the WWTP is 22.8 mgd and the peak sustained flow capacity is 16. The average flow during dry weather periods for the month of January was 5.75 mgd or 111 % of the plant capacity (5.2~mgd). The average flow during the entire month of January was measured to be 7.06 G:\SDA T A \@PEH\901--950\944\002\WRD\Review of EMC\Review of EMC Operations - January 2004 memo. doc , Beview of EMC WWTP Operations - January 2004 I?age 2 April 8, 2004 mgd or 136% of the plant capacity (5.2-mgd). The peak daily flow reached 16.3 mgd on January 4th, above the "rated" capacity of 16 mgd. Rainfall in January was 4.8 inches, a little higher than the typical January rainfall of 4.25 inches. Effluent Ouality: The second page of graphs show the plant performance for effluent CBOD, TSS, and ammonia compared to the weekly average and monthly average effluent limits. The 7-day moving average (MV A) effluent concentration is used to compare to the weekly permit limit and the 28-day moving average effluent limit is used to compare to the monthly average effluent limit. January is the second month of 'less stringent' winter effluent limits. The WWTP did not violate any conventional permit limits during January. · Effluent CBOD concentrations were below permit limits. · Effluent TSS concentrations were below the permit limits. · Effluent NH3-N concentrations were below the permit limits. Activated Sludge Process: The third page of graphs shows typical activated sludge parameters. · The first graph shows the food to mass of volatile organisms (F:Mv) ratio. For extended aeration activated sludge wastewater treatment plants, the target F:Mv is typically between 0.08 and 0.1. The activated sludge plant averaged 0.09 for January. · The next graph shows the sludge volume index (SVI). SVlis an indicator of settleability of the mixed liquor. SVls below 150 are not cause for concern. SVI above 150 suggests poor settling characteristics. SVI levels for the month of January averaged 210 and seemed to have leveled off. This is on the high side and should be monitored closely. ,The high SVls are characteristic of wintertime operation and does not appear to be the result of old sludge. EMC remains prepared to add polymer to their final clarifiers if necessary. · The next graph shows the organic loading rate for the oxidation ditch activated sludge process. Your activated sludge process was designed with an OLR of 15-lb BOD/day/WOO cf. The 28-day running average OLR varied between 17.4 and 20 throughout the month. The high end is attributed to the high influent BOD following rain events. The average OLR was 19 lb BOD/day/WOO cf which is higher than usual due to the extreme loadings noted. No violations of effluent limits occurred. · The next graph includes the solids loading rate (SLR), a measure of the mass of solids in the influent to the clarifiers. "Ten States Standards" limits the solids loading rate to less than 35 lb/d/sf of clarifier surface area. The chart shows the daily, 7-day MV A and 28-day MV A SLR. The SLR has been averaging about 16-lb/d/sf with a daily peak of 30-lb/d/sf for the month of January. We have included a chart that shows the daily SVI and SLR data versus the curve from WEF MOP 8 and a curve specific to the Jeffersonville plant. This Jeffersonville curve was created by reviewing data from peak wet weather events over a three-year period as part of the CSOP update. Operation above this curve has resulted in effluent TSS violations. The chart demonstrates that the plant is generally operating below the "textbook" and Jeffersonville curves. · The next plot is for mixed liquor suspended solids (MLSS in mgIL). The MLSS concentration of the activated sludge plant varied between 1,300 and 3,920 mgIL averaging about 3,371 mg/L. The single low measurement appears to be the result of collecting a non-representative sample. (Initials]G:\SDA T A \@PEH\901--950\944\002\WRD\Review of EMC\Review of EMC Operations - January 2004 memo.doc\040804 sa. STRAND ASSOCIATES,INC." ENG1NESRS r;' Review of EMC WWTP Operations - January 2004 Page 3 April 8, 2004 . Typically MLSS ranges from 2,500 to 4,500 mgIL for the extended aeration process and these results fall well within this range. EMC no longer targets a MLSS concentration to control the process; they now target a constant sludge age. In the past, when the MLSS concentration dipped below 2,000 mgIL the nitrification process was affected. The next graph shows the mixed liquor volatile suspended solids (ML VSS in mg/L) ML VSS has been varying between 936 mgIL and 2,822 mg/L with an average of 2,367 mg/L. The single low measurement appears to be the result of collecting a non-representative sample. This range is reasonable. The ML VSS shows the same trending as the MLSS graph. The historical minimum ML VSS to sustain complete nitrification appears to be 1,800 mg/L based on previous operational data. The next graph shows the yield of solids from the activated sludge process. The yield is defined as the pounds of TSS produced per pound of BOD removed. For an extended aeration activated sludge plant, a yield between 0.8 and 1.1 is reasonable. )'Qur plant had the 28-day moving average yield of 0.62, a lower number than typical. The last graph shows the Sludge Age, a measure of the average time a microorganism spends in the activated sludge system. We recommended that the. actiyat~d sludge process be operated to maintain a constant sludge age rather than a constant MLSS. The average sludge age during the month was 20 days with the targeted sludge age being between 20 and 22 days. . . In summary, the activated sludge process is performing well (BOD, TSS, and NH3-N removal). The average SVI levels began increasing in November. We recommend adding an anoxic zone preceding the oxidation ditch to improve the poor settleability of the sludge observed in early 2000, early 2001, late 2001, early 2002, early 2003 and again in late 2003. Such a tank could be added during a major reconstruction process, due to the need to disrupt process flow. In the interim, EMC may be able to operate aerators at low speed for times to create anoxic conditions; this should be initiated with great caution as evidenced by the increasing effluent CBOD concentrations when attempted in mid-August 2000. The proposed anoxic one (or selector tank) is under design now.

Sneve, P.E. ~ April 8, 2004 Review ofEMC CSS Operation - January & February 2004 We have completed our review of EMC's Combined Sewer System (CSS) operations. The purpose of our review was to evaluate CSS data and operation strategies to verify that EMC is operating the CSS in accordance with the approved CSOP and in the best interest of the City of Jeffersonville. To complete our evaluation, we have reviewed EMC's CSO DMRs. Strand Associates also met with EMC to discuss CSS operation and implementation status of the CSOP. EMC inspected the CSOs on a daily basis throughout the workweek and documented the overflow status on inspection logs. There were no dry-weather CSO discharges in January and February. January 2004 A total of 4.8 inches of rain feel during January. The historic average total rainfall for January is about 4.25 inches; thus January 2004 had slightly above-average rainfall. During the month of January there was one rain event that resulted in 4 CSOs (Walnut St., Meigs Ave., Graham St., 10th Street PS) discharging. Table 1 provides a summary of the rainfall events and the discharges that occurred during the month. During these CSO events, EMC was able to avoid a CSO from the separate sanitary system pump stations (Spring Street, Mill Creek, Arctic Springs). Six additional days had measurable rain without the CSS overflowing. January 1-2 - CSO Event - The CSO events that occurred on January 1 and 2 began at approximately 6:00 AM at Walnut Street and lasted for about 3 hours, the Meigs Ave. CSO event occurred at 9:00 AM and lasted for 3 hours, the Graham St. CSO event occurred at 8:00 AM and lasted for 4 hours, the 10th St. PS CSO event occurred at 6 AM and lasted for 5 hours. The peak flow received at the treatment plant was 25.0 mgd, which is above the 3-hour peak flow capacity of 22.8 mgd for the facility. February 2004 A total of 1.85 inches of rain feel during February. The historic average total rainfall for February is about 2.75 inches; thus February 2004 had below-average rainfall. During the month of February there were two rain events that resulted in 2 CSOs (Meigs Ave. and 10th Street PS) discharging. Table 1.. provides a summary of the rainfall events and the discharges that occurred during the month. During \\PEHLOUFOl\V0L1\SDATA\@PEH\901--950\944\002\WRD\Review ofCSO\Review ofEMC CSS - J-F04 memo.doc Review ofEMC CSS Operations - January & February 2004 Page 2 April 8, 2004 tl1ese CSO events, EMC was able to avoid a CSO from the separate sanitary system pump stations (Spring Street, Mill Creek, Arctic Springs). February 2 - CSO Event - The CSO events that occurred on February 2nd began at approximately 9:00 PM at Meigs Ave. and lasted for about 1 hour. The peak flow received at the treatment plant on February 2nd was 25.0 mgd, which is above the 3-hour peak flow capacity of 22.8 mgd for the facility. February 5 - CSO Event - The CSO events that occurred on February 5th began at approximately 5:00 PM at the 10th Street PS. and lasted for about 2 hours. The peak flow received at the treatment plant on February 5th was 25.0 mgd, which is above the 3-hour peak flow capacity of 22.8 mgd for the facility. A meeting was held with EMC to discuss several CSO related matters. A status report on the identified action items is provided below in bold. 1. EMC will contact Significant Industrial Users discharging to the Tenth Street Pump Station to see if they have the ability to hold back wastewater in their pretreatment systems when the Tenth Street pump station is overflowing. Any such reduction in industrial flow will reduce the CSO volume and will keep industrial pollutanw ou, of the overflow. EMC will contacC'PQ Corporation, George Pfau, and Alumnitec (now called Altech). EMC received letters from PQ, cmq. Alltec regarding wet weather discharg~redl.lPtion. Pfau has verbally agreed with EMC to reduce their flow during these events,but;'.EMC'has yet to receive a letter. EMC wi1l request these industries to keep records of reduced discharges during CSO operations for the benefit of demonstrating regulatory compliance. EMC will also consider adding a SCADA alarm setpoint to the Tenth Street PS wetwelllevel to trigger placing a call to these industries. This initiative is fully implemented. EMC has successfully requested these industries detain their flow and the industries are very willing to do so. Of the three industries listed, only PQ corporation operates 24/7. The industries report to EMC on their success in detaining flow during CSO events in their monthly Self Monitoring Report. 2. EMC will meet with Wyandot foods and arrange for them to hold their wastewater flow in their equalization tank if EMC notifies them. EMC will request a short duration stop in discharge if they need to shut off pumps in the Tenth Street PS. The net effect will be a reduction in CSO volume if Wyandot can accommodate the request. EMC has sent a letter to Wyandot. Wyandot has sent a letter and agreed to attempt to detain discharges during CSO events. Efforts complete, same status as No.1. 3. EMC will keep track of the number of CSO catch basins and combined sewers cleaned on a monthly basis. EMC currently tracks these efforts, but does not differentiate between the CSS and the rest of the system. Efforts are underway. Nearly all of the catch basins cleaned by EMC are in the combined sewer system (CSS). Public works cares for the catch basins outside the [Initials]\\PEHLOUFOl \VOLl\SDA TA \@PEH\901--950\944\002\WRD\Review of CSO\Review ofEMC CSS - J-F04 memo,doc\040804 sa. STRANO ASSOC1ATES,INC.'" ENGINEERS >' Review of EMC CSS Operations - January & February 2004 Page 3 April 8, 2004 CSS. In January & February, EMC cleaned and vactored 257 catch basins, cleaned 188 catch basin inlets, and cleaned 17,518 LF of combined sewer in the CSS. 4. EMC will track and report any basement backups or property owner complaints in the CSS. EMC currently tracks these efforts, but does not differentiate between the CSS and the rest of the system. EMC will attempt to database all basement backups in the CSS. They will review historical files to help start the database. One backup was reported in July but was due to tree root intrusion and not rainfall. The affected portion of mainline was replaced to correct this problem. EMC's efforts continue. No backups were reported in January & February. 5. EMC will begin printing daily flow and level charts from the SCADA system for the primary lift stations. EMC is working with the SCADA programmer to create a database or spreadsheet with such critical information. EMC has implemented this recommendation. SCADA programming has been modified to allow capture of flow and level information. Graphs have been printed as of July 1 and electronic data has been captured since August 1. Fully implemented. 6. EMC will prepare a SOP for the routine inspection and preventive maintenance of the flood control sluice gates. These gates protect the CSS from flooding when the Ohio River floods. EMC will inspect these semi-annually. PEH will assist EMC in modifying their SOPs for flood gate operation to: protect the CSS from backwater yffects'~uring an Ohio River flood. A SOP,bas been prepared by Strand and EMC. EMC greases and operates these gates monthly. The Penn Street gate will be operated and maintain~d, byFJood Control due to its location., 7. EMC will attempt to coordinate the Tenth Street PS wet well level with the flooding of the lowest basement on Spring Street (Southern IN Pediatrics). In the future, wet well levels approaching this critical elevation will be monitored and the backflow prevention gate will be lifted to reduce headloss and avoid backup into this basement. EMC reports the only time the basement floods is when they have to shut off a pump at Tenth Street PS. Shutting off pumps at Tenth Street PS is a critical to the flexibility of operating the CSS system. A backwater or isolation valve should be installed to isolate this basement from flooding. JTL was going to survey elevations to allow for a hydraulic analysis. Work is ongoing. 8. EMC will dye trace the Power House and Camp Powers lift stations to confirm their discharge locations. EMC will also evaluate if roof drains are connected to the Power House lift station and the discharge location for any overflow from the Power House lift station. Power House Lift Station was confirmed to pump to Camp Powers Lift Station. Efforts complete. 9. EMC and PEH will meet with the City Attorney to discuss holding a meeting with the Falls of the Ohio State Park regarding notification following CSO events that discharge into the upper pool of the Ohio River. Meeting with City Attorney held in July. A letter is being prepared to be sent to the Falls and other affected users. These efforts have been completed as part of the new CSO public notification program. Efforts complete.

The ability to add three real-time rain gauges and connection to the SCADA system will be investigated. Locations have been selected (Tenth Street PS, Spring Street PS, and Louise Street PS). These locations would provide reasonably good coverage of the CSS. EMC worked with the SCADA programmer to install the rain gauges and modify the SCADA system. The rain gauges are installed and operational as of February 13, 2004. EMC will request the SCADA system capture and store complete data collected by these rain gauges. 11. The ability to add an inspection manhole for CSO confirmation at the Penn Street overflow will be evaluated. Presently, the overflow structure is in a Flood Control structure and cannot be routinely inspected. It is now believed that this sewer cannot overflow and the long-term control plan is considering removing it from the KPDES permit. 12. EMC will televise a sewer on the Jeffboat property that may intersect the Market Street interceptor between Penn and Graham. This sewer may turn out to be a storm sewer or, at worst case, a new combined sewer overflow. EMC has confirmed this is the CSO outfall from the Penn Street Overflow. Efforts complete. 13. EMC confirmed the wetwell settings in the SCADA system for Tenth Street, Mill Creek and Spring Street Pump stations. EMC has reprogrammed the SCADA settings and now has confidence inthecelevations required before an overflow oscurs:; Efforts complete. ~.::; ~,!. 14. EMC and PER attempted to dye trace the discharge'!frol1'1Loui,se Street and Ewing Lane Pump station CSOs. It was confirmed that Ewing Lane does not have a combined sewer overflow and the Louise Street PS CSO has been grouted full and cannot overflow. We recommend eliminating these CSOs from the City's NPDES permit as part of the long term control plan. Efforts complete. 15. EMC will attempt to provide some sort of visual evidence that can be checked and reset at individual CSO weirs on the Market Street interceptor. The purpose of this will be to more accurately assess if a CSO has overflowed from one day to the next. EMC's efforts l~ontinue. EMC has installed a few prototypes that have failed to be durable enough to be considered a long-term solution. EMC continues to experiment with this effort. 16. The flap gate inst(!1led at the outfall of the Tenth Street PS to prevent back-up of WWTP effluent into the pump station during high river stages has resulted.in additional back pressure. EMC continues to manually open and close the flap gate during rain events. Jorge Lanz has recommended keeping the gate open to determine if there is a possible restriction. EMC is concerned about adding new storm sewer infrastructure to the downstream side of this gate and further increasing the back pressure. JTL is evaluating. A permanent hoist should be installed to avoid using the truck-mounted hoist. Efforts continue.

EMC and PEH reviewed maps and conclude these combined sewers were known and would contribute to overflows at Graham Street CSO. Efforts complete. 18. The new CSO Public Notification plan was prepared, adopted and implemented since the last monthly report. A public meeting was held, letters were sent to potentially affected parties and public notices were placed in the Evening News. Newspaper articles were printed in both the Evening News and the Courier Journal. The list of parties requesting direct notification of potential overflow has been assembled. EMC will implement the program beginning in March. The status of these items will be reported on in future monthly reports.
