The Permit was renewed in CY2019 with an effective date of December 1, 2019. The CMOM Plan consists of the following documents: 1. FOG Policy 2. CMOM Annual Report 3. CMOM Program Self-Assessment The CY2020 CMOM Annual Report follows previous FY2013-17 and CY2017-19 reports. The previous reports, as well as the most recent, can be accessed at https://www.abcwua.org/sewersystem-overview/. Appendix 4 provides a summary of goals established in this CY2020 CMOM Report. Report Purpose As indicated by its name, the CMOM Annual Report will be reissued to describe CMOM activities in the previous calendar year (January 1 to December 31). The CMOM Annual Report provides summary descriptions of CMOM activities (past and planned) and is intended to be a communication tool. The report is intended for Water Authority staff, regulatory authorities, customers, and the general public. Page 2 of 21 Permit Requirements The Water Authority discharges to the Rio Grande under authority of NPDES Permit No. NM0022250 (Permit). Under this Permit, the Water Authority operates the Southside Water Reclamation Plant (SWRP) and the Collection System. The Permit was renewed effective December 1, 2019. The following are the Permit requirements that impact the collection system. 1. The Water Authority shall report all overflows with a (monthly) Discharge Monitoring Report (DMR). (Part I, Paragraph D). 2. Overflow reporting requirements were unchanged for EPA and NMED. (Part I, Paragraph D). 3. Overflow reporting requirements were modified for spills impacting the Pueblo of Isleta (POI) were modified in accordance with the "Pueblo of Isleta Reporting Requirement" which were a subsection of the renewed Permit. (Part I, Paragraph D and "Pueblo of Isleta Reporting Requirement".) 4. The Water Authority shall continue to implement and update (if necessary) the CMOM plan. (Part II, Paragraph E.) The full permit is available at https://cloud.env.nm.gov/water/pages/view.php?ref=6881&k=fd428af5b1 CMOM Program Self-Assessment EPA states (see https://mwrd.org/sites/default/files/documents/USEPA_3-cmomselfreview.pdf): "An important component of a successful CMOM program is to periodically collect information on current systems and activities and develop a "snapshot-in-time" analysis. From this analysis, the utility establishes its performance goals and plans its CMOM program activities." The Water Authority developed Self-Assessments as a part of the FY2013 and FY2014 reports. Because the data provided in the Self-Assessment does not significantly change year-to-year, the Water Authority has set a goal of updating the Self-Assessment every five years. Therefore, the CMOM Program Self-Assessment CY2018 has been prepared and posted to https://www.abcwua.org/sewer-system-overview/ along with the CMOM Reports. Rather than being an appendix to the CMOM Report, it is now a stand-alone document. The next update will coincide with the CY2023 CMOM Report. Page 3 of 21 FOG Policy The Water Authority's FOG Policy is a separate document. The FOG Policy was developed as a requirement of the NPDES Permit effective on October 1, 2012 and subsequently approved by the United States Environmental Protection Agency (EPA). The policy was developed to work in conjunction with the Water Authority Sewer Use and Wastewater Control Ordinance (SUO) and Enforcement Response Plan (ERP) to reduce the rate of SSOs in the collection system and decrease FOG loading at the SWRP. The policy describes expectations for FOG dischargers such as Food Service Establishments (FSEs) and waste haulers, and the steps the Water Authority is taking to mitigate FOG. The FOG Policy sets a Water Authority goal of inspecting every FSE at least once every three years. Details of what is expected of the FSE in terms of Grease Removal System (GRS) functionality, pumping schedule, maintenance, and recordkeeping are identified. The FOG policy explains the Water Authority use of the 25% solids and grease rule (25 Percent Rule) to determine if a GRS is filled to capacity. The policy also contains Best Management Practices (BMPs) such as scraping plates, using screens, and not using emulsifiers, etc. Pumper requirements are also covered in the FOG Policy. Full evacuation of a GRS is required each time pumping occurs. The pumper must leave the FSE documentation in the form of manifests that contain pertinent information such as date, time, volume pumped, and the condition of the GRS. The FOG Policy lists the minimum service to be provided by the pumper. Enforcement of FOG violations and hauled wastewater violations is described in the FOG Policy. The FOG Policy works in conjunction with the ERP to set administrative assessments for violations. The FOG Policy also sets forth the process for identifying new sources of FOG. The Water Authority Pretreatment Program will update the FOG database on an annual basis. The FOG Policy sets a goal that the Water Authority will meet with the City of Albuquerque, Bernalillo County, the Village of Los Ranchos, the Village of Corrales, plumbers, and the New Mexico Restaurant Association on a periodic basis to discuss FOG issues. In developing the FOG Policy, the Water Authority held a meeting with the hauled wastewater permit holders on July 22, 2013 and a public meeting on July 25, 2013 to discuss the proposed Policy. The final FOG Policy was submitted to the EPA on September 27, 2013 and updated in the Pretreatment Program modification documents sent to EPA on June 2, 2014. No comments from EPA were received regarding either submission, thus indicating approval. FOG Enforcement In CY2020, the Water Authority Pretreatment Program had 1,725 compliant FSEs out of 2,151 FSE sites for a compliance rate of 80%. Seventy-three (73) FSE inspections were conducted with 46 passing, and 27 failing. Of the 27 failed inspections, 21 Notices of Violation were issued. Eight (8) of the 21 violations were resolved and the remainder are outstanding. In response to SSOs, ten (10) FSE inspections were conducted with three (3) passing and seven (7) failing. Of the seven (7) failed inspections, three (3) Notice of Violations were issued and four (4) were corrected before issuance of violations. Page 4 of 21 In addition, Water Authority Pretreatment personnel distributed FOG brochures to FSEs, singlefamily residences and apartment complexes upstream of the SSOs. Additionally, the Water Authority's Public Information Office advanced radio, print and television public outreach for the purpose of improving the Water Authority's FOG Policy. SSO Analyses Permit Requirements The Permit requires a CMOM Plan. The Plan goal is to reduce SSOs. The FOG Policy states that the Pretreatment Program will investigate all SSOs related to large amounts of grease. The policy is to take enforcement actions for violations of FOG requirements with priority on FSEs causing repeat SSOs. SSO Study Team To meet these requirements, the Water Authority created an SSO Study Team. The Team is comprised of: 1. Collection Section - Research Analyst (team lead), Gravity Superintendent, Assistant Superintendent and Closed Circuit Television (CCTV) Supervisor; 2. NPDES Pretreatment -Industrial Pretreatment Engineer and Pollution Prevention Specialist. The Mission Statement for the Study Team is: The SSO Study Team will work inter-divisionally to study, analyze and determine causes of previous SSOs to mitigate future SSOs in the Collection System. The Study Team procedure is: 1. Tabulate all 10-40s, 10-42s and 10-48s (see Table 1 for definitions). 2. Ensure all segments responsible for causing 10-42s and 10-48s are televised. 3. The Research Analyst will review and analyze all CCTV inspections to determine causes (if possible) and document findings. 4. To conduct meetings with the SSO Study Team to review and analyze CCTV that needs further investigation for resolution. 5. Recommend/implement and document mitigations (if possible) based on analysis. 6. Coordinate with NPDES Pretreatment concerning grease issues discovered during analysis.

Does not result in an SSO Reportable (10-42) or a Property Damage (10-48). An overflow of sewage from the system that may impact surface waters. These are reported to the EPA and other locally impacted stakeholders. 10-48 Property Damage An overflow of sewage from the system that results in damage to private property. These are not reportable under current definitions. Appendix 1 identifies all 10-42s and 10-48s, and the overflows that resulted in both a 10-42 and a 10-48. When documenting the number of Sewer Troubles of different types, for example in Figure 1 and Figure 2, the 10-42 item includes all overflows that may impact surface waters, including those that also had property damage; the 10-48 item includes overflows that only resulted in property damage. This prevents double-counting the number of overflow occurrences. All 10-40s, 42s and -48s were CCTV inspected, although only 10-42s are "reportable", i.e., required to be reported to the EPA, et al. All 10-42s and -48s were then examined by the Study Team and a Cause and Mitigation were determined.

The monthly SSO DMR has a specific list of Causes that are based on system observations made by an Operator or Supervisor at the site of an SSO. The CCTV data provided to the Study Team often results in a different, more refined Cause or Causes. Table 3 provides the causes determined by the Study team for CY2020. (Note: Percentages may not add up to 100%, as they are rounded to the nearest percent.)

In CY2020, 33% of mitigations included performing rehab or replacement of the line, whereas in CY2019 more segments were added to the short interval cleaning program. This indicates the condition of infrastructure where SSOs are occurring. Table 4 provides a summary of the various Mitigations. The Mitigations are tracked through completion or implementation.

Figure 1 Reportable SSOs Page 8 of 21 Appendix 1 contains a list of every 10-42 and 10-48 event in CY2020. The table columns are grouped as follows: 1. The type, i.e., 10-42 or -48, is identified on the left. In one case a single event was both a 10-42 and a 10-48, as indicated. 2. Next to the right are the data included in the monthly SSO DMRs. It is noted that a "Reported Cause" is listed. This is typically based on the observations of the Operator that reported the SSO. 3. Next to the right is data determined by the Study Team: a. Cause b. Mitigation c. If Pretreatment follow-up is necessary 4. To the far right are follow-ups by NPDES Pretreatment a. FSEs visited b. Notice of Violation issued The SSO Rate is defined as 100 times the number of SSOs in a year divided by the miles of sewer in the system. The Water Authority system has a total of approximately 2,414 miles of line (p. 8 of the Self-Assessment). The SSO rate is therefore 3.4, 3.0, 1.8, 2.2, 1.4, 1.7, 1.1, 1.1 and 0.7 for CY2012-20 respectively. Figure 2 shows the total sewer troubles, i.e. 10-40s, -42s, and -48s by year for CY2012-20. This graph does not include 10-48s due to "burps" which are not due to a blockage or other failure resulting in the overflow of sewage. Instead, air displaced during the Vactor jetting cleaning can under certain circumstances force out the water in the home fixture P-traps, e.g. toilets and sinks. These sometimes result in claims and are therefore included in the Property Damage totals for completeness and consistency. There was only one burp during CY 2020. This burp is identified in Appendix 1.

Appendix 1 provides the Ultimate Discharge Location for each reported SSO. Appendix 2 provides estimated spill volumes and volumes recovered for 17 reported SSOs for CY2020. Of the spill volume estimated not to be recovered, none was identified as directly reaching the Rio Grande. No spills reached a facility operated by the MRGCD. It was estimated that approximately 54% of the estimated spill volume was recovered in CY2020 as shown in Appendix 2. Page 10 of 21 Actions Implemented and On-Going Programs General Below are gaps that were identified in the CY2019 CMOM Report and were closed in CY2020, or are on-going programs, or both. In addition to the commitments made in the CMOM Report, in CY2020, the following additional actions were taken to expand the Water Authority's ability to operate and maintain the system. 1. Two new Vactors were obtained and put into service. 2. Interceptor manhole inspection was performed using a panoramic camera on 100 manholes in CY2020. In CY2021, approximately 260 additional manholes will be inspected. 3. The Water Authority's Corrective Maintenance Report now includes the distance from the downstream manhole to a blockage. 4. The Water Authority's Public Affairs section continued to support SSO prevention efforts and the FOG Policy in CY2020 by reprising an advertising campaign aimed at discouraging disposal of improper materials in household drains and planting trees near sewer lines. A news release ran for the Thanksgiving Day holiday. Appendix 3 displays the news release. In addition to the holiday release, the media campaign is still in place with ads on television, radio, outdoor boards, social media, and water bill inserts. FOG Policy Implementation: The FOG Policy is an on-going program and FOG Enforcement efforts are a part of this program. Both the FOG Policy and the FOG Enforcement efforts are described above. On-going efforts are described in the FOG Enforcement section and not reiterated here. The Water Authority has long had an FSE flier in English. An FSE flier was developed and implemented in CY2019 and a goal was set to develop an FSE flier in Chinese. However, it was determined that a Vietnamese flier was more prudent and this was developed in CY2020. The Water Authority has a three-year plan to distribute these fliers to all FSEs and continue to improve FOG inspections. Overflow Emergency Response Plan (OERP) This is an on-going program to update the OERP as required. In CY2020, no modifications were made were made to the OERP. The Collection Section is the "owner" of the OERP. The Collection Section creates the components of the OERP, routes for internal review (specifically including the Compliance Division), and the completed portions are approved for posting to SharePoint by the Collection Section Manager. Appendix 4 provides the OERP which was in effect at the end of CY2019. The most current version of the OERP is posted to http://www.abcwua.org/Sewer_System.aspx Page 11 of 21 Closed Circuit Television (CCTV) This is an on-going program. The following recommendation is made in the FY2013 CMOM Report: "CCTV inspections of the collection system as follows: 1) Small diameter main lines less than 15": In four of five years, televise approximately 5% per year of the small diameter system. Televise high risk lines based on current Asset Management Plan and subsequent inhouse analysis. 2) Large diameter lines 15" and larger: Every fifth year, televise as much as possible acknowledging access limitations of the unlined concrete lines 15" and larger. Anticipated schedule: 3) FY2014-17: 5% of the small diameter each year. 2) FY18: Large diameter unlined concrete pipe." CMOM Report figures for cleaning and CCTV will continue showing fiscal year (FY) goals in accordance with funding and contracting cycles and actual metrics will reflect work through the end of the calendar year (CY). Figure 4 provides the CCTV goal for a ten-year basis and the actual CCTV inspection through CY2020. The CY2020 portion of this recommendation is complete. The CCTV program will continue. Anticipated schedule: 1. FY21: 5% of the small diameter. 2. FY22: 5% of the small diameter. 3. FY23: Large diameter unlined concrete pipe. 4. FY24: 5% of the small diameter. 5. FY25: 5% of the small diameter. 6. FY26: 5% of the small diameter. Figure 3 Small Diameter Sewer CCTVed vs. Ten-Year Goal Page 12 of 21 Cleaning Program Goal This is an on-going program. The following recommendation is made in the FY2013 CMOM Report: "The Water Authority will establish and monitor a goal of cleaning all gravity small diameter lines every ten years. (This will be accomplished through the existing Sub-Basin program.) The Water Authority will continue the program of high-frequency maintenance of known problem locations within the system. (This will be accomplished through the existing Short Interval program.) The frequency of Short Interval cleaning will vary in accordance with system performance and risk factors, maintenance history, and the latest maintenance findings." CMOM Report figures for cleaning and CCTV will continue showing fiscal year (FY) goals in accordance with funding and contracting cycles and actual metrics will reflect work through the end of the calendar year (CY). As shown Figure 5, the Water Authority is ahead of its goal to clean then entire system once in ten years through the Sub-Basin program. The Sub-Basin program and associated ten-year cleaning goal remain in place. While meeting this CMOM commitment for Sub-Basin cleaning, the Collection Section has increased Short Interval cleaning. The Water Authority is studying SSO rates in the Short Interval and the non-Short Interval portions of the Collection System. These studies are on-going and not yet complete. A possible outcome is a determination that total SSOs may be reduced by increasing the Short Interval cleaning per year and therefore decreasing the Sub-Basin cleaning per year. If so, the Water Authority would establish and monitor a different cleaning goal. This new goal would be established in a subsequent CMOM Annual Report. Figure 4 Small Diameter Sewer Cleaned vs. Ten-Year Goal Page 13 of 21 Force Main Inspection Program This is an on-going program in which the alignment is annually inspected for all force mains and valves found in field are compared to those in the GIS mapping and this information is stored in Maximo. Lift Station 20 pumps westside flow to the Southside Water Reclamation Plant (SWRP) via twin 30" ductile iron force mains. Per the CY2019 CMOM report, an air pocket profile was completed using a smart ball on the north force main in CY2020. A report was received and from development of this air pocket profile, air release valves (ARVs) were identified for replacement or relocation in coordination with the SWRP. In CY2021, the Water Authority will install replacement ARVs and then perform additional smart ball tests on both force mains. Root Foaming The following recommendation is made in the FY2013 CMOM Report: "Starting in FY15, implement a 3-year pilot program. Root foam selected lines that meet the root infested and / or inaccessibility criteria. Compare effectiveness to mechanical cleaning currently practiced and provide recommendation." The Root Foaming Pilot Project is a three-year treatment program with follow-up study. The FY15 and FY16 groups were foamed in June 2015 and March 2016 respectively. Per vendor recommendations, the FY15 group was retreated in June 2017. This completed the foaming application portion of the Pilot Project. An interim inspection of the FY15 treated and control group was performed in FY2016 and was inconclusive. During FY2017, the FY15 and FY16 lines, both treated and control, were scheduled for CCTV inspection. In CY2018, this CCTV data was examined to compare treated and control pipes but was inconclusive. In CY2019, the review continued. In CY2020, the final report for the Root Foaming Pilot project was completed. The report concluded that a root foaming program should not be implemented. Instead, efforts should be focused on existing cleaning programs specifically evaluating the effectiveness of the Short Interval program (frequency, selected lines, time of year, etc.). Odor Complaints Odor complaints are tabulated and reported monthly. The Water Authority odor control program is described in the CMOM Self-Assessment Report in the Hydrogen Sulfide Monitoring and Control (HSMC) section in the current CMOM Program Self-Assessment. Portable odor control carbon units were implemented in CY2020. Page 14 of 21 Identified Gaps in the Water Authority Processes with Recommendation to Close In the process of continuous improvement, the Water Authority is committed to identifying and closing gaps. As discussed above, most of these recommendations are now considered On-Going programs. Prohibited Discharges, i.e., SSOs The Water Authority acknowledges that prohibited discharges have occurred and that all discharges from the sanitary sewer system are prohibited. Recommendation: The Water Authority will annually examine sewer system performance, set specific steps for decreasing SSOs and mitigating their impacts, and has a program of continuous improvement.

Billboards and TV and radio spots resurrect last year's "spokes-elephant," who points out that it makes as much sense to put a pachyderm down the sink as it does to pour grease down the drain. FOG - Fats, Oils, and Grease - is a leading cause of sewer overflows, which in turn can cause thousands of dollars in property damage and create a public health threat. Water Authority customers are asked to do their part to prevent costly and hazardous sewer overflows: 1) Dispose of cooking grease in the trash, not the sink. Kitchen grease should be poured into a can or milk carton or soaked up with a paper towel and thrown into the garbage for disposal at the landfill. Otherwise it can collect and harden in the sewer system. For the same reason, greasy food scraps should be thrown away, not put in the garbage disposer. Remember: Cool it, Can it, Chuck it! 2) Don't put rags or disposable wipes down the sink or toilet. Rags of any sort--even ones advertising themselves as "flushable"--can cause sewer blockages, especially if they get caught on tree roots. Rags and disposable wipes should be thrown into the garbage for disposal at the landfill. 3) Plant trees well away from sewer lines. Roots grow toward breaks and cracks in sewer lines in search of water. Once they've penetrated a pipe, the roots can cause blockages leading to sewer overflows. Appendix 4 Overflow Emergency Response Plan (OERP) Page 20 of 21 Overflow Emergency Response Plan Albuquerque Bernalillo County Water Utility Authority Customer calls dispatch with issue Dispatch collects data and creates a Service Request; Task elevated to supervisor Note: All Emergency responses are initiated by a call to Dispatch at 842WATR (842-9287).

The Permit was renewed in CY2019 with an effective date of December 1, 2019. The CMOM Plan consists of the following documents: 1. FOG Policy 2. CMOM Annual Report 3. CMOM Program Self-Assessment The CY2021 CMOM Annual Report follows previous FY2013-17 and CY2017-20 reports. The previous reports, as well as the most recent, can be accessed at https://www.abcwua.org/sewersystem-overview/. Appendix 5 provides a summary of goals established in this CY2021 CMOM Report. Report Purpose As indicated by its name, the CMOM Annual Report will be reissued to describe CMOM activities in the previous calendar year (January 1 to December 31). The CMOM Annual Report provides summary descriptions of CMOM activities (past and planned) and is intended to be a communication tool. The report is intended for Water Authority staff, regulatory authorities, customers, and the general public. Page 2 of 26 Permit Requirements The Water Authority discharges to the Rio Grande under authority of NPDES Permit No. NM0022250 (Permit). Under this Permit, the Water Authority operates the Southside Water Reclamation Plant (SWRP) and the Collection System. The Permit was renewed effective December 1, 2019. The following are the Permit requirements that impact the collection system. 1. The Water Authority shall report all overflows with a (monthly) Discharge Monitoring Report (DMR). (Part I, Paragraph D). 2. Overflow reporting requirements were unchanged for EPA and NMED. (Part I, Paragraph D). 3. Overflow reporting requirements were modified for spills impacting the Pueblo of Isleta (POI) were modified in accordance with the "Pueblo of Isleta Reporting Requirement" which were a subsection of the renewed Permit. (Part I, Paragraph D and "Pueblo of Isleta Reporting Requirement".) 4. The Water Authority shall continue to implement and update (if necessary) the CMOM plan. (Part II, Paragraph E.) The full permit is available at https://cloud.env.nm.gov/water/pages/view.php?ref=6881&k=fd428af5b1 CMOM Program Self-Assessment EPA states (see https://mwrd.org/sites/default/files/documents/USEPA_3-cmomselfreview.pdf): "An important component of a successful CMOM program is to periodically collect information on current systems and activities and develop a "snapshot-in-time" analysis. From this analysis, the utility establishes its performance goals and plans its CMOM program activities." The Water Authority developed Self-Assessments as a part of the FY2013 and FY2014 reports. Because the data provided in the Self-Assessment does not significantly change year-to-year, the Water Authority has set a goal of updating the Self-Assessment every five years. Therefore, the CMOM Program Self-Assessment CY2018 has been prepared and posted to https://www.abcwua.org/sewer-system-overview/ along with the CMOM Reports. Rather than being an appendix to the CMOM Report, it is now a stand-alone document. The next update will coincide with the CY2023 CMOM Report. Page 3 of 26 FOG Policy The Water Authority's FOG Policy is a separate document. The FOG Policy was developed as a requirement of the NPDES Permit effective on October 1, 2012 and subsequently approved by the United States Environmental Protection Agency (EPA). The policy was developed to work in conjunction with the Water Authority Sewer Use and Wastewater Control Ordinance (SUO) and Enforcement Response Plan (ERP) to reduce the rate of SSOs in the collection system and decrease FOG loading at the SWRP. The policy describes expectations for FOG dischargers such as Food Service Establishments (FSEs) and waste haulers, and the steps the Water Authority is taking to mitigate FOG. The new NPDES Permit was effective December 01, 2019, allowing for an update to the Industrial Pretreatment Program. This update started with an amendment to the SUO, board approved on July 05, 2021. This amendment updated the FOG section to include solids and standardize the terminology to match plumbing code and industry standards and include Hydromechanical Grease Interceptor exclusions to the 25% rule. Fats, Oils, and Grease (FOG) is now Fats Oils, Grease and Solids (FOGS). Grease Removal Systems (GRS) are now referred to as Grease Interceptors (GI). HGIs being more efficient GIs are allowed to hold up to 50% grease and solids. The FOGS Policy and ERP are currently under revision to reflect SUO changes and bolster both documents. The FOG Policy sets a Water Authority goal of inspecting every FSE at least once every three years. Details of what is expected of the FSE in terms of Grease Removal System (GRS) functionality, pumping schedule, maintenance, and recordkeeping are identified. The FOG policy explains the Water Authority use of the 25% solids and grease rule (25 Percent Rule) to determine if a GRS is filled to capacity. The policy also contains Best Management Practices (BMPs) such as scraping plates, using screens, and not using emulsifiers, etc. Pumper requirements are also covered in the FOG Policy. Full evacuation of a GRS is required each time pumping occurs. The pumper must leave the FSE documentation in the form of manifests that contain pertinent information such as date, time, volume pumped, and the condition of the GRS. The FOG Policy lists the minimum service to be provided by the pumper. Enforcement of FOG violations and hauled wastewater violations is described in the FOG Policy. The FOG Policy works in conjunction with the ERP to set administrative assessments for violations. The FOG Policy also sets forth the process for identifying new sources of FOG. The Water Authority Pretreatment Program will update the FOG database on an annual basis. The FOG Policy sets a goal that the Water Authority will meet with the City of Albuquerque, Bernalillo County, the Village of Los Ranchos, the Village of Corrales, plumbers, and the New Mexico Restaurant Association on a periodic basis to discuss FOG issues. In developing the FOG Policy, the Water Authority held a meeting with the hauled wastewater permit holders on July 22, 2013 and a public meeting on July 25, 2013 to discuss the proposed Policy. The final FOG Policy was submitted to the EPA on September 27, 2013 and updated in the Pretreatment Program modification documents sent to EPA on June 2, 2014. No comments from EPA were received regarding either submission, thus indicating approval. The Sewer Use and Wastewater Control Ordinance was updated and approved by the Board in July 2021. The Pretreatment Program documents including the FOGS and Enforcement Policies have been Page 4 of 26 revised to match the Ordinance updates and are expected to be submitted to EPA for approval once the legal review is complete, by December 2022. FOG Enforcement In CY2021, the Water Authority Pretreatment Program had 1,718 compliant FSEs out of 2,135 FSE sites for a compliance rate of 80%. Three hundred-sixty-seven (367) FSE inspections were conducted with 222 passing, and 145 failing. Of the 145 failed inspections, 77 Notices of Violation were issued. Thirty-three (33) of the 77 violations were resolved and the remainder are outstanding. In response to SSOs, twelve (12) FSE inspections were conducted with five (5) passing and seven (7) failing. Of the seven (7) failed inspections, zero (0) Notice of Violations were issued and all were corrected before issuance of violations. In addition, Water Authority Pretreatment personnel distributed FOG brochures to FSEs, singlefamily residences and apartment complexes upstream of the SSOs. Additionally, the Water Authority's Public Information Office advanced radio, print and television public outreach for the purpose of improving the Water Authority's FOG Policy. Page 5 of 26 SSO Analyses Permit Requirements The Permit requires a CMOM Plan. The Plan goal is to reduce SSOs. The FOG Policy states that the Pretreatment Program will investigate all SSOs related to large amounts of grease. The policy is to take enforcement actions for violations of FOG requirements with priority on FSEs causing repeat SSOs. SSO Study Team To meet these requirements, the Water Authority created an SSO Study Team. The Team is comprised of: 1. Collection Section - Research Analyst (team lead), Gravity Superintendent, Assistant Superintendent and Closed Circuit Television (CCTV) Supervisor; 2. NPDES Pretreatment -Industrial Pretreatment Engineer and Pollution Prevention Specialist. The Mission Statement for the Study Team is: The SSO Study Team will work inter-divisionally to study, analyze and determine causes of previous SSOs to mitigate future SSOs in the Collection System. The Study Team procedure is: 1. Tabulate all 10-40s, 10-42s and 10-48s (see Table 1 for definitions). 2. Ensure all segments responsible for causing 10-42s and 10-48s are televised. 3. The Research Analyst will review and analyze all CCTV inspections to determine causes (if possible) and document findings. 4. To conduct meetings with the SSO Study Team to review and analyze CCTV that needs further investigation for resolution. 5. Recommend/implement and document mitigations (if possible) based on analysis. 6. Coordinate with NPDES Pretreatment concerning grease issues discovered during analysis.

Does not result in an SSO Reportable (10-42) or a Property Damage (10-48). An overflow of sewage from the system that may impact surface waters. These are reported to the EPA and other locally impacted stakeholders. Property Damage An overflow of sewage from the system that results in damage to private property. These are not reportable under current definitions. Appendix 1 identifies all 10-42s and 10-48s, and the overflows that resulted in both a 10-42 and a 10-48. When documenting the number of Sewer Troubles of different types, for example in Figure 1 and Figure 2, the 10-42 item includes all overflows that may impact surface waters, including those that also had property damage; the 10-48 item includes overflows that only resulted in property damage. This prevents double-counting the number of overflow occurrences. All 10-40s, 42s and 48s were CCTV inspected, although only 10-42s are "reportable", i.e., required to be reported to the EPA, et al. All 10-42s and 48s were then examined by the Study Team and a Cause and Mitigation were determined.

The monthly SSO DMR has a specific list of Causes that are based on system observations made by an Operator or Supervisor at the site of an SSO. The CCTV data provided to the Study Team often results in a different, more refined Cause or Causes. Table 3 provides the causes determined by the Study team for CY2021. (Note: Percentages may not add up to 100%, as they are rounded to the nearest percent.)

The table columns are grouped as follows: 1. The type, i.e., 10-42 or -48, is identified on the left. In one case a single event was both a 10-42 and a 10-48, as indicated. 2. Next to the right are the data included in the monthly SSO DMRs. It is noted that a "Reported Cause" is listed. This is typically based on the observations of the Operator that reported the SSO. 3. Next to the right is data determined by the Study Team: a. Cause b. Mitigation c. If Pretreatment follow-up is necessary 4. To the far right are follow-ups by NPDES Pretreatment a. FSEs visited b. Notice of Violation issued The SSO Rate is defined as 100 times the number of SSOs in a year divided by the miles of sewer in the system. The Water Authority system has a total of approximately 2,414 miles of line (p. 8 of the Self-Assessment). The SSO rate is therefore 3.4, 3.0, 1.8, 2.2, 1.4, 1.7, 1.1, 1.1, 0.7 and 0.5 for CY2012-21 respectively. Figure 2 shows the total sewer troubles, i.e. 10-40s, -42s, and -48s by year for CY2012-21. This graph does not include 10-48s due to "burps" which are not due to a blockage or other failure resulting in the overflow of sewage. Instead, air displaced during the Vactor jetting cleaning can under certain circumstances force out the water in the home fixture P-traps, e.g. toilets and sinks. These sometimes result in claims and are therefore included in the Property Damage totals for completeness and consistency. There were only two burps during CY 2021. These burps are identified in Appendix 1.

Appendix 1 provides the Ultimate Discharge Location for each reported SSO. Appendix 2 provides estimated spill volumes and volumes recovered for 12 reported SSOs for CY2021. Of the spill volume estimated not to be recovered, none were identified as directly reaching the Rio Grande. No spills reached a facility operated by the MRGCD. It was estimated that approximately 83% of the estimated spill volume was recovered in CY2021 as shown in Appendix 2. Page 11 of 26 Actions Implemented and On-Going Programs General Below are gaps that were identified in the CY2020 CMOM Report and were closed in CY2021, or are on-going programs, or both. In addition to the commitments made in the CMOM Report, in CY2021, the following additional actions were taken to expand the Water Authority's ability to operate and maintain the system. 1. Interceptor manhole inspection was performed on 260 additional manholes for a total of 360 manholes inspected from CY2020 and CY2021. The data is being used for an Interceptor Manhole Asset Management Plan to determine which manholes should be prioritized for rehabilitation or replacement. 2. The Water Authority updated the public website (https://www.abcwua.org/sewercollection-section/ ) to provide more information about the Collection Section and make the website more user friendly. The "Keeping Elephants Out of Sewer Game," created by Stephanie Ramsey, Ph. D., was added to the website as a tool to teach the public how to prevent SSOs. 3. The Water Authority's Public Affairs section continued to support SSO prevention efforts and the FOG Policy in CY2021. Appendix 3 identifies media specifics for water bill inserts, social media, and advertising in television, radio, newspaper, outdoor boards, and digital. 4. On April 7, 2021, Collection Section staff met virtually with the North and South Divisions of LA Sanitation and Environment - Clean Water Conveyance. During the meeting, operating and management staff discussed cleaning methods and working in traffic conditions. Page 12 of 26 FOG Policy Implementation The FOG Policy is an on-going program and FOG Enforcement efforts are a part of this program. Both the FOG Policy and the FOG Enforcement efforts are described above. On-going efforts are described in the FOG Enforcement section and not reiterated here. The Water Authority has long had an FSE flier in English. An FSE flier in Spanish was developed and implemented in CY2019 and a goal was set to develop an FSE flier in Chinese. However, it was determined that a Vietnamese flier was more prudent and this was developed in CY2020. The Water Authority has a three-year plan to distribute these fliers to all FSEs and residential units during SSO investigations to continually improve education to the rate payers on the negative impacts of FOG. In CY2022, improve FOG inspections by using advance inspection tools. Overflow Emergency Response Plan (OERP) This is an on-going program to update the OERP as required. In CY2020 and CY2021, no modifications were made were made to the OERP. The Collection Section is the "owner" of the OERP. The Collection Section creates the components of the OERP, routes for internal review (specifically including the Compliance Division), and the completed portions are approved for posting to SharePoint by the Collection Section Manager. Appendix 4 provides the OERP which was in effect at the end of CY2019. The most current version of the OERP is posted to http://www.abcwua.org/Sewer_System.aspx The Albuquerque Metropolitan Arroyo Flood Control Authority (AMAFCA) and the Water Authority continued coordination in 2021. On April 4, 2021, both organizations participated in a virtual brainstorming meeting. Discussion included improvements in capturing and removing spills prior to reaching the Rio Grande. Page 13 of 26 Closed Circuit Television (CCTV) This is an on-going program. The following recommendation is made in the FY2013 CMOM Report: "CCTV inspections of the collection system as follows: 1) Small diameter main lines less than 15": In four of five years, televise approximately 5% per year of the small diameter system. Televise high risk lines based on current Asset Management Plan and subsequent inhouse analysis. 2) Large diameter lines 15" and larger: Every fifth year, televise as much as possible acknowledging access limitations of the unlined concrete lines 15" and larger. Anticipated schedule: 3) FY2014-17: 5% of the small diameter each year. 2) FY18: Large diameter unlined concrete pipe." CMOM Report figures for cleaning and CCTV will continue showing fiscal year (FY) goals in accordance with funding and contracting cycles and actual metrics will reflect work through the end of the calendar year (CY). Figure 3 provides the CCTV goal for a ten-year basis and the actual CCTV inspection through CY2021. The CY2021 portion of this recommendation is complete. The CCTV program will continue. Anticipated schedule: 1. FY21: 5% of the small diameter. 2. FY22: 5% of the small diameter. 3. FY23: Large diameter unlined concrete pipe. 4. FY24: 5% of the small diameter. 5. FY25: 5% of the small diameter. 6. FY26: 5% of the small diameter. Figure 3 Small Diameter Sewer CCTVed vs. Ten-Year Goal Page 14 of 26 Cleaning Program Goal This is an on-going program. The following recommendation is made in the FY2013 CMOM Report: "The Water Authority will establish and monitor a goal of cleaning all gravity small diameter lines every ten years. (This will be accomplished through the existing Sub-Basin program.) The Water Authority will continue the program of high-frequency maintenance of known problem locations within the system. (This will be accomplished through the existing Short Interval program.) The frequency of Short Interval cleaning will vary in accordance with system performance and risk factors, maintenance history, and the latest maintenance findings." CMOM Report figures for cleaning and CCTV will continue showing fiscal year (FY) goals in accordance with funding and contracting cycles and actual metrics will reflect work through the end of the calendar year (CY). As shown Figure 4, the Water Authority is ahead of its goal to clean then entire system once in ten years through the Sub-Basin program. The Water Authority has performed detailed analyses of SSO rates in the Water Authority collection system. These analyses show that: 1. The Short Interval lines consistently experience a higher SSO rate than the Sub-Basin lines. This indicates that even more cleaning of Short Interval lines, with a commensurate decrease in Sub-Basin cleaning, will result in a net reduction of total SSOs in the system. This is because the additional cleaning would be applied to lines more likely to spill, and to be taken from lines less likely to spill. 2. The upstream portion of the Sub-Basin lines are less likely to spill than the downstream portion. These findings provide the opportunity to clean the sewers more effectively and efficiently with the goal of SSO reduction, therefore, in CY2022: 1. The Water Authority will establish and monitor a temporary goal of cleaning all gravity small diameter lines every fifteen years. (This will be accomplished through the existing Sub-Basin program.) The Water Authority will continue the program of high-frequency maintenance of known problem locations within the system. (This will be accomplished through the existing Short Interval program.) The frequency of Short Interval cleaning will vary in accordance with system performance and risk factors, maintenance history, and the latest maintenance findings. This will maintain the Sub-Basin program as currently configured while targeting the Short Interval lines which are more likely to spill. 2. The Water Authority will continue studies with the intent is to validate prior study indicating a significant SSO Rate variation for top versus bottom, and therefore the opportunity to optimize sub-basin cleaning. A possible outcome will be modification of the Sub-Basin program to remove lines shown to be significantly less likely to spill. Page 15 of 26 Figure 4 Small Diameter Sewer Cleaned vs. Ten-Year Goal Force Main Inspection Program This is an on-going program in which the alignment is annually inspected for all force mains and valves found in field are compared to those in the GIS mapping and this information is stored in Maximo. Lift Station 20 pumps westside flow to the Southside Water Reclamation Plant (SWRP) via twin 30" ductile iron force mains. In CY2021, the Water Authority performed a test using the smart ball and installed replacement ARVs on both force mains. Odor Complaints Odor complaints are tabulated and reported monthly. The Water Authority odor control program is described in the CMOM Self-Assessment Report in the Hydrogen Sulfide Monitoring and Control (HSMC) section in the current CMOM Program Self-Assessment. Page 16 of 26 Identified Gaps in the Water Authority Processes with Recommendation to Close In the process of continuous improvement, the Water Authority is committed to identifying and closing gaps. As discussed above, most of these recommendations are now considered On-Going programs. Prohibited Discharges, i.e., SSOs The Water Authority acknowledges that prohibited discharges have occurred and that all discharges from the sanitary sewer system are prohibited. Recommendation: The Water Authority will annually examine sewer system performance, set specific steps for decreasing SSOs and mitigating their impacts, and has a program of continuous improvement.
