At the time of the inspection, Lyons Creek MHC, LLC was identified as the Permittee since they are listed in the Permit as the Permit holder. Horizon Land Co. LLC took over ownership of the Plant in 2015 and are defined in this report as Discharger. Singh Operational Services has been hired to contract operate the Plant since April 1, 2020. The Inspectors were joined by a member from the Maryland Department of the Environment (MDE) and Discharger representatives (as listed in the Introduction section of the report). The Plant is a package style sewage treatment plant with activated sludge and extended aeration. The collection system comprises 2.87 miles of gravity mains, with mostly polyvinyl chloride (PVC) pipes and some clay and Orangeburg pipes. Wastewater flows by gravity to the Plant through an influent manhole. Wastewater flows through a manually-raked bar screen at the influent end of the package plant and into the aeration chamber. Activated sludge is piped in near this location as well. From the aeration chamber, flow is routed to a central clarifier chamber, then into a clarified effluent wet well before being pumped into a building with a rotary cloth filter unit (out of service). After the filter building, effluent is disinfected via ultraviolet (UV) light and flows through a final filter unit prior to being discharged into a pipe in the ground which is connected to the outfall to Lyons Creek (Outfall 001), a tributary of the Patuxent River, designated as Use-I waters, which is protected for water contact and recreation and nontidal warm water aquatic life. The Plant services approximately 250 mobile home pads with an approximate population of 900 people and is operated 1.5-2 hours per day, 7 days per week. Solids from the activated sludge process are collected in small section of the package plant and pumped into a waste tank. Wastes solids are hauled off by a contractor as needed. Activities at the site are regulated under National Pollutant Discharge Elimination System (NPDES) Permit No. MD0053511 (hereinafter, Permit), which became effective on January 1, 2017 and is set to expire on December 31, 2021. During the inspection, the Discharger representatives indicated that they were in the process of reapplying for Permit coverage (due to MDE by December 31, 2020). The primary purpose of the inspection was to review the accuracy and reliability of the Discharger's selfmonitoring and reporting program and to obtain information that will assist EPA in assessing the Discharger's compliance with the requirements of the Permit. The Inspectors held discussions with Discharger representatives, conducted a detailed site inspection, and reviewed pertinent documentation regarding compliance with the Permit. Based on the information obtained and reviewed, the Inspectors made several observations related to the specific Permit requirements evaluated. These observations are summarized in Table E-1. Photographs from the inspection are included as Appendix A. Supporting documents are included as Appendix B.

INTRODUCTION On December 1, 2020, U.S. Environmental Protection Agency (EPA) Region III's contract inspectors from PG Environmental, (hereinafter referred to as Inspectors) inspected the Lyons Creek Mobile Home Park Wastewater Treatment Plant (hereinafter, WWTP or Plant) in Lothian, Maryland. At the time of the inspection, Lyons Creek MHC, LLC was identified as the Permittee since they are listed in the Permit as the Permit holder. Horizon Land Co. LLC took over ownership of the Plant in 2015 and is defined for the purpose of this report as Discharger. Singh Operational Services has been hired to contract operate the Plant since April 1, 2020. The Inspectors were joined by a member from the Maryland Department of the Environment (MDE) and Discharger representatives. The primary purpose of the inspection was to review the accuracy and reliability of the Discharger's self-monitoring and reporting program as well as the operation and maintenance of the Plant. The weather at the time of the inspection was cold, with periods of light precipitation. The Facility is a package style sewage treatment plant with activated sludge and extended aeration. The collection system comprises 2.87 miles of gravity mains, with mostly polyvinyl chloride (PVC) pipes and some clay and Orangeburg pipes. Wastewater flows by gravity to the Plant through an influent manhole. Wastewater flows through a manually-raked bar screen at the influent of the Plant and then into the aeration chamber. Activated sludge is piped in near this location as well. From the aeration chamber, flow is routed to a central clarifier chamber, then into a clarified effluent wet well before being pumped into a building with a rotary cloth filter unit. After the filter building, effluent is disinfected via ultra-violet (UV) light and flows through a final filter unit prior to being discharged into a pipe in the ground which is connected to the outfall to Lyons Creek (Outfall 001). Lyons Creek is a tributary of the Patuxent River, which is designated as Use-I waters and is protected for water contact and recreation and non-tidal warm water aquatic life. The Plant services approximately 250 mobile home pads with an approximate population of 900 people and is operated 1.5-2 hours per day, 7 days per week. Per the Permit fact sheet, the design capacity of the Plant is 70,000 gallons per day (GPD) (refer to Attachment B, Exhibit 1). During the inspection, Discharger representatives stated that the Plant routinely averages flows of 60,00080,000 GPD, with wet weather peaks over 100,000 GPD. Solids from the activated sludge process are collected in small section of the package plant and pumped into a waste tank. Wastes solids are hauled off by a contractor as needed. Activities at the site are regulated under National Pollutant Discharge Elimination System (NPDES) Permit No. MD0053511 (hereinafter, Permit), which became effective on January 1, 2017, and is scheduled to expire on December 31, 2021 (refer to Attachment B, Exhibit 2). The following personnel were involved in the inspection: Horizon Land Co. LLC Representatives (Discharger Representatives): Rikki Drykerman, General Counsel, Horizon Land Co. LLC Emmett Conneely, Project Manager, Horizon Land Co. LLC Singh Operational Services Representatives (Discharger Representatives): Chandra Singh, Owner, Singh Operational Services Lyla Walrath, Business Manager, Singh Operational Services Michael Case, Environmental Scientist, Singh Operational Services EPA Inspectors: Jake Albright, PG Environmental (contractor) Taylor Fontaine, PG Environmental (contractor) MDE Representative: Shailaja Polasi, Regulatory Compliance Engineer Unique Project Identifier: 3E21WN003A 4 Inspection Date: December 1, 2020 Lyons Creek Mobile Home Park WWTP (MD0053511) Compliance Evaluation Inspection Report II. INSPECTION PROCESS The Inspectors held discussions with Discharger representatives, conducted a detailed site inspection, and conducted a records review of pertinent documentation regarding compliance with the Permit. This report documents the Inspectors' observations. Facility Site Walk As part of the process, the Inspectors visually observed the treatment train and site conditions in the presence of MDE and Discharger representatives. The treatment train consists of: Influent manhole; Influent bar screen; Aeration tank; Clarifier; Secondary clarifying trough and wet well chamber/clarified effluent pumps; Rotary cloth filter (out of service); UV light disinfection; and Secondary filter (unknown media); Effluent discharge channel, including Parshall flume and ultrasonic transducer for flow measurement. At the time of the inspection, the Plant had a backup generator onsite, which was being exercised weekly. It should be noted the Inspectors were unable to view the outfall at the time of the inspection due to safety concerns relative to the surrounding terrain. Records Review The Inspectors conducted a records review to evaluate the Discharger's compliance with the Permit. Most of the records and reports required by the Permit were available for review after the inspection. The daily handwritten operational datasheets were reviewed onsite during the inspection. The Plant's electronic discharge monitoring reports (eDMRs) were provided electronically and reviewed offsite after the onsite inspection. The following documents were reviewed: eDMR data during the period from January 1, 2017 (Permit effective date through October 31, 2020); Flow calibration record for ultrasonic transducer (UT) utilized with Parshall flume flow meter (May 21, 2020) (refer to Attachment B, Exhibit 3); Operations log (April 1, 2020 to date of inspection); DMR-Monthly Operating Report (MOR) log sheets (January 2020 to October 2020); Daily handwritten operational datasheets (April 1, 2020 to date of inspection); Records of field pH and chlorine meters calibration (October and November 2020) (refer to Attachment B, Exhibit 4); and UV system service quote (December 4, 2020). III. SUMMARY OF OBSERVATIONS The following section summarizes the Inspectors' observations relative to the Discharger's Permit requirements, including the status of certain treatment units, operation and maintenance practices, and the Discharger's monitoring and reporting documentation. Unique Project Identifier: 3E21WN003A 5 Inspection Date: December 1, 2020 Lyons Creek Mobile Home Park WWTP (MD0053511) Compliance Evaluation Inspection Report A. Permit Status and Effluent Exceedances Part II.A of the Permit defines effluent limitations and monitoring requirements for Outfall 001 discharges. According to EPA's Integrated Compliance Information System (ICIS) database, the Plant experienced 22 effluent limit exceedances from Outfall 001 between January 1, 2017 and October 31, 2020 (i.e., since the Permit took effect, refer to Attachment B, Exhibit 5). It should be noted that data was coded in ICIS for two different locations, Monitoring Location 001-A from January 1, 2017 - July 31, 2019, and 001-B from August 1, 2019 - present. It is unclear why there are two monitoring locations in the database for Outfall 001. EPA's Enforcement and Compliance History Online (ECHO) Database indicates the Plant was in a state of significant noncompliance (SNC) continuously between April 1, 2020 and October 31, 2020 (refer to Attachment B, Exhibit 6). ECHO indicated that violations had been identified during the quarter encompassing the date of the inspection and indicated SNC. Table 1.

Footnote (1) of the Permit states, "There shall be no discharge of floating solids or visible foam in other than trace amounts." Based on the records review, the majority of the Plant's exceedances were related to TSS. During the inspection, the Inspectors observed solids issues throughout the treatment train. For example, bulking solids were observed floating in the clarifier and solids were observed on the clarifier weirs. Additionally, the clarifier skimmer arm was missing at the time of the inspection. Inspectors also observed scum and foam floating in the effluent channel of the UV system. Observations related to solids and the condition of the treatment train are included in Observation 3. The Inspectors also observed more than 30 entries documented in the Plant's logbook between April 1, 2020 and November 19, 2020 that referred to the Plant's effluent as "cloudy" or "foggy" (refer to Attachment B, Exhibit 7). There were several other entries that included the terms "mostly" or "pretty" clear when referring to the effluent. There were numerous entries that did not describe the clarity of the effluent. This observation was made after the onsite inspection and not reviewed with the Discharger representatives at the time of the Inspection. B. Proper Operation and Maintenance Permit Part II.B.3, Facility Operation and Quality Control requires that "All waste collection, control, treatment and disposal facilities shall be operated in a manner consistent with the following: a. Facilities shall be operated efficiently to minimize upsets and discharges of excessive pollutants." The Inspectors made several observations related to operations and maintenance at the Plant: The influent bar screen was full of sewage material (rags and solids) at the time of the inspection. Discharger representatives stated that the screen is cleaned daily, and it had not yet been cleaned on the day of the inspection. He also stated the condition observed was typical. Daily influent bar screen cleaning was observed to be documented in the Plant's logbook (refer to Attachment B, Exhibit 7). Foam was in the aeration chamber (refer to Attachment A, Photographs 2 and 4). During the inspection, Discharger representatives attributed the foaming to microorganisms in the plant biology as well as sludge age (i.e., old sludge). Unique Project Identifier: 3E21WN003A 7 Inspection Date: December 1, 2020 Lyons Creek Mobile Home Park WWTP (MD0053511) Compliance Evaluation Inspection Report Bulking solids were observed floating in the clarifier and solids were observed on the clarifier weirs (refer to Attachment A, Photographs 3 and 4). During the inspection, Discharger representatives attributed the solids to microorganisms in the plant biology as well as sludge age (i.e., old sludge). Solids/scum were also observed in the clarifier effluent wet well (refer to Attachment A, Photograph 5). The clarifier skimmer arm was not in operation at the time of the inspection. This same observation was also made in the January 9, 2020 MDE inspection report (refer to Attachment B, Exhibit 8). The January 9, 2020 MDE inspection report recommended "necessary repairs should be made to the skimmer arm immediately". These repairs had not been made at the time of the December 1, 2020 inspection. The Inspectors observed the skimmer arm placed against a chain link fence on the outer perimeter of the Plant. Discharger representatives stated that the skimmer arm had been removed for more than two years. One of the two clarifier effluent pumps was not present at the time of the inspection. Discharger representatives were unsure of when it was taken out or why (refer to Attachment A, Photograph 5). The outer ring of the Plant, which could be used for additional capacity or emergency storage, was filled with solids and vegetation (refer to Attachment A, Photograph 6). Light brown solids and scum were observed on the water surface at the effluent end of the UV channel (refer to Attachment A, Photograph 7). There was no observable odor at the time of the inspection. The Plant's rotary cloth filter unit was not in operation at the time of the inspection. The filter was positioned immediately upstream of the UV disinfection banks. Discharger representatives stated the unit had been out of service for decades. At the time of the inspection, effluent was being channeled through the non-functioning rotary cloth filters to the UV banks. As stated previously, light brown solids and scum were observed on the water surface at the effluent end of the UV channel. There was no observable odor at the time of the inspection. The UV transmittance indicator was flashing at the time of the inspection and read 0.4-0.5 mW/cm2 (refer to Attachment A, Photograph 8). At the time of the inspection, the Plant operator stated the UV transmittance indicator does not necessarily need to provide an exact reading as it is just used to signal an issue. On December 4, 2020, Discharger representatives solicited quotes for repair work on the UV transmittance indicator (refer to Attachment B, Exhibit 9). This same observation was also made in the January 9, 2020 MDE inspection report (refer to Attachment B, Exhibit 8). The Inspectors observed a tall green rectangular filter unit downstream of the UV system, prior to the final effluent channel and discharge location (refer to Attachment A, Photograph 9). At the time of the inspection, Discharger representatives were unsure of the type of filter media in use or why the filter was installed downstream of disinfection. The filter unit is not described in the Permit fact sheet (refer to Attachment B, Exhibit 1). Unique Project Identifier: 3E21WN003A 8 Inspection Date: December 1, 2020 Lyons Creek Mobile Home Park WWTP (MD0053511) Compliance Evaluation Inspection Report The Discharger did not have a Plant operations and maintenance (O&M) manual or standard operating procedures (SOPs) for critical Plant processes at the time of the inspection. The Inspectors observed the Plant's discharge to be going into a pipe located in a hole in the ground upstream of Outfall 001 (refer to Attachment A, Photograph 10). The pipe was lower than the surrounding grade and the ground surface in the vicinity was mostly dirt and gravel. It appeared that sediment would be able to enter the pipe during a wet weather event and ultimately be discharged to Lyons Creek through Outfall 001. Part II.C of the Permit states that if the Plant's "most recent three year average flow is over 80% of its design capacity or if it is anticipated to exceed 80% in the following year, a Wastewater Capacity Management Plan (WCMP) must be submitted to the Department using NetDMR no later than January 28 of the following year. Thereafter, the "Wastewater Flow Capacity Report (WFCR)" and "worksheet for WFCR" shall be submitted to the Department using NetDMR tool no later than January 28th of each year." The Permit fact sheet lists the design capacity of the Plant as 70,000 GPD (refer to Attachment B, Exhibit 1). At the time of the inspection, the Plant operator stated that dry weather flows to the Plant are routinely in the 70,000 to 80,000 GPD range, with wet weather peaks over 100,000 GPD. This was confirmed by eDMR data in ICIS (refer to Attachment B, Exhibit 5). The ICIS monthly average flow data indicates that the Plant averaged within 80 percent of the design flow (i.e., 56,000 GPD) 29 times during the Permit term and higher than the design flow 10 times during the Permit term (see Table 3). Based on the average monthly flow data in ICIS, the Plant has averaged 63,000 GPD (i.e., 90 percent of the design flow) between January 2017 and October 2020 (46 months). According to the MDE representative onsite, the Discharger had not submitted a WFCR at the time of the inspection.

Special Requirements and Conditions Page No. 7 Outfall: 001A WWTP meeting at least 85% reduction of BOD5 and TSS Yes No N/A Based on the plant performance records for the period Jan 2011- Dec 2015, the effluent BOD5 and TSS are averaged 2.2 mg/l and 2.4 mg/l, respectively. Using BOD5 and TSS concentration of 200 mg/l for typical raw-sewage influent (as stated in the technical manuals), this facility removes more than 98 % of BOD5 and TSS during the treatment processes, far exceeding the minimum 85% removal requirement for POTWs with the secondary treatment. Rationale: 40CFR, PART 133, 133.102 Enhanced Nutrient Removal (ENR) Requirements: ENR Limits ENR Goal N/A As per the Maryland's Chesapeake Bay ENR Strategy for Point Sources, this facility has been assigned with the annual maximum Waste Load Allocation (WLA) goals estimated at xxxx pounds/year for TN and yyy pounds/year for TP which are part of the aggregate nutrient WLAs assigned to the nonsignificant point sources within the Chesapeake Bay Segment (e.g. POTTF_MD). Because this facility has less than 0.1 mgd flow capacity, the Departmental Guidelines exempts this facility from the annual maximum waste load limits as well as goal requirements. The above nutrient WLAs for this facility will be incorporated to establish the limits, if the existing facility is expanded in future. Rationale: Maryland's Chesapeake Bay Tributary Strategy Statewide Implementation Plan, 2008 and Chesapeake Bay Watershed Implementation Plan TMDL Implementation Requirements: Yes No N/A This permit is in conformance with the "Chesapeake Bay TMDL for Nitrogen, Phosphorus and Sediment" established on December 29, 2010. Rationale: 40 CFR 130.7, The approved TMDL(s) for TN, TP, & TSS in Patuxent River Watershed}. Was Whole Effluent Toxicity (WET) testing required in the previous discharge permit (09-DP-1275)? Yes No N/A SUMMARY REPORT & FACT SHEET (Application No. 12-DP-1275) II. Special Requirements and Conditions Page No. 8 Outfall: 001A Is WET testing proposed for the permit?

XX.x = In-stream waste concentration% %. Are WET limits proposed? Yes No N/A Was Toxic Chemical Testing required in the previous discharge permit (09-DP-1275)? Yes No N/A No priority pollutant testing is recommended for the renewal discharge permit. Standard influent restriction requirements for a non-pretreatment minor facility is recommended for the renewal discharge permit. Is Toxic Chemical Testing proposed? Yes No N/A If Yes: Chemical testing for toxic substances is required for POTWs with flows greater than 1,000,000 gpd or a pretreatment program, a discharger that has demonstrated actual or potential toxicity, or a discharger whose discharge the Department believes may cause toxicity as determined by an evaluation of manufacturing processes, indirect discharges, treatment processes, effluent or receiving water data, or other relevant information. Rationale: COMAR 26.08.03.07D(1) and MDE's "Toxic Pollutant Analytical and Reporting Requirements Protocol, revised on 5/18/2011" SUMMARY REPORT & FACT SHEET (Application No. 12-DP-1275) II. Special Requirements and Conditions Page No. 9 Outfall: 001A Wastewater Capacity Management Does the proposed permit include condition pertaining to the wastewater flow capacity management? Yes No If NO, provide brief explanation for exemption (Example: The facility serves {TYPE OF ENTITY} which does not have growth potential in future). If Yes, does the proposed permit require submittal of Capacity Management Plan (CMP)? Yes No Because the most recent three-year annual average wastewater flow is 70 % of the existing rated capacity of 0.07 MGD which does not exceed a threshold of 80 % capacity. Rationale: MDE's Guidance Document "Wastewater Capacity Management Plans, 2006" Pretreatment Program/Influent Restriction WWTP with approved pretreatment program Non-pretreatment program WWTP Does the non-pretreatment WWTP require the influent restriction? Yes No Rationale: COMAR 26.08.08 and Department Guidelines Reapplication Due Date for Next Permit Renewal Per the Departmental guidelines for the watershed permitting, the next renewal of a discharge permit for the Lyons Creek MHC, LLC WWTP is scheduled for 1st quarter, 4th year in cycle with the projected renewal application date of 01/01/2017 and reissuance date of 04/01/2018. Because the reapplication due date of 01/01/2017 for the next permit renewal would be within two years from the anticipated issuance date of the proposed permit, the reapplication due date is set as 12 months before the expiration date of the proposed permit. Rationale: COMAR 26.08.04.01 and Departmental Guidelines. Are temperature requirements included? Yes No SUMMARY REPORT & FACT SHEET (Application No. 12-DP-1275) Page No. 10 Outfall: 001A III. Proposed Effluent Limits and Monitoring Requirements The effluent limits and monitoring requirements, as listed below, are proposed to process the application for the discharge permit renewal. Refer to Appendix- A for the previous permit's effluent limitations and monitoring requirements. The quality of the effluent discharged by the facility at the discharge location- 001A(1) (2) (3) (4) shall be limited and/or monitored at all times as shown below.

Notification is to be provided to the Department at least 180 days before the annual average flow is expected to exceed this flow level. If a permit modification is required, the Department will initiate the public participation NPDES process. Footnotes: For Effluent Limitations (1) When this permit is renewed, the new limitations may not be equal to the above limitations. (2) There shall be no discharge of floating solids or visible foam other than trace amounts. (3) The permit may also be reopened in accordance with the requirements of MDE's Watershed Permitting Plan under which all discharge permits in a watershed are issued the same year. (4) The Middle and Lower Patuxent River (02-13-11-02 and 02-13-11-01) are on the 303(d) list as impaired waters for Sediment, Nutrient, Chlorpyrifos, Fecal coliform and Biological communities. Total Maximum Daily Load (TMDL) for chlorpyrifos has been completed in the Middle Patuxent River (02-13-11-02) and approved by the EPA on 7/3/2007. Chlorpyrifos and fecal bactria TMDLS approved by EPA have also been completed in the Lower Patuxent River SUMMARY REPORT & FACT SHEET (Application No. 12-DP-1275) Page No. 12 Outfall: 001A III. Proposed Effluent Limits and Monitoring Requirements (02-13-11-01) watershed. This permit is in conformance with the "Chesapeake Bay TMDL for Nitrogen, Phosphorus and Sediment" established on December 29, 2010. When TMDLs for other remaining parameters are completed, limits may be imposed, after the public participation process, to incorporate any TMDL requirements. (5) Total residual chlorine limitation of 0.011 mg/l shall be applicable, when chlorine or any chlorine- containing compound is used in any treatment process(es), including but not limited to disinfection, that could become a potential constituent of the effluent discharged from the Lyons Creek MHC, LLC. The wastewater shall be dechlorinated to reduce effluent total residual chlorine concentration to the nondetectable level (See definition I.L of the draft permit). For Monitoring Requirements (6) "STORET" (short for STOrage and RETrieval) is a widely-used repository for water quality data reporting and monitoring. The STORET codes for the effluent characteristics described as limitations and/or monitoring requirements are: BOD5 (00310), Total Suspended Solids (00530), Total Ammonia Nitrogen as N (00610), E. Coli (51040), Total Residual Chlorine (50060), Dissolved Oxygen (00300), pH (00400), (7) The Minimum monitoring requirements of one per day-grab samplings for total residual chlorine shall be applicable, when chlorine or any chlorine compound is used in any treatment process(es), including but not limited to disinfection, that could become a potential constituent of the effluent discharged from the Lyons Creek MHC, LLC. The minimum detection level (quantification level) for total residual chlorine is 0.10 mg/l. The permittee may report all results below the minimum level as <0.10 mg/l. All results reported below the minimum level shall be considered in compliance. (8) Flows shall be reported in millions gallons per day (mgd) to at least the nearest 1,000 gallons per day. (Example: A flow of 24,699 gallons per day shall be reported as 0.025 mgd.). For each calendar month, flows shall be reported on the MOR as daily individual results and on the DMR as monthly average (mgd) and daily maximum (mgd)). (9) Continuous electronic flow measurement and recording which can produce a permanent record are acceptable to the Department. Regulations and Rationale for Effluent Limitations: Regulations: 40 CFR 130.7, COMAR 26.08.02.03-3A(2), COMAR 26.08.04.04C(1) and COMAR 26.08.0l.01B(80). BOD5 Discussion and Rationale(s): The technical analysis was performed in 1993 using a mathematical model (INPRG) to establish the effluent limits requirements for discharge flows up to 0.07 MGD. There is no increase of the discharge flow for the permit renewal; and also, there are no indications of apparent changes to the receiving stream. Therefore, the BOD5 and dissolved oxygen effluent limits established in 1993 and incorporated in previous permit(s) 82-DP-1275, 95-DP-1275 & 09-DP-1275 have been considered at this time for the proposed permit renewal. These limits will be protective of meeting the dissolved oxygen criteria in downstream portion of the effluent receiving stream(s). SUMMARY REPORT & FACT SHEET (Application No. 12-DP-1275) Page No. 13 Outfall: 001A III. Proposed Effluent Limits and Monitoring Requirements Total Suspended Solids (TSS) Regulations: 40 CFR 130.7, COMAR 26.08.02.03-3A(5), COMAR 26.08.04.04C(1), COMAR 26.08.0l.01B(80) and 40 CFR133.102 - 133.105. Discussion and Rationale(s): The Chesapeake Bay TMDL (Phase I) approved by USEPA on 12/29/2010 allocated the aggregate annual TSS waste load to cover all non-significant point sources which are located into the Chesapeake Bay Water Quality Segment-02-13-11-02, rather than individual sources. The limit of 30 mg/l monthly average is in conformance to the Bay TMDL. Total Kjedahl Nitrogen (TKN) Regulations: COMAR 26.08.02.03-3A(2) Discussion and Rationale(s): Refer to Discussion and Additional Rationale forBOD5. Regulations: COMAR 26.08.02.03-2J, COMAR 26.08.02.03-2K and COMAR 26.08.02.05C, COMAR 26.08.02.05D. Total Ammonia Nitrogen as N Discussion and Rationale(s): The reasonable potential of the Lyons Creek WWTP effluent to cause a violation of the receiving stream's ammonia water quality criteria was investigated to process the discharge permit renewal. An in-house SPREADSHEET program (developed by the Municipal Surface Discharge Permits Division) was used as a tool for the toxicity analysis. The dilution factors, based on the applicable mixing zone criteria, were incorporated in the analysis. As the ammonia toxicity criteria are pH dependent, the effluent pH of 7.6 which is a median of the maximum effluent pH data for the period Jan 2011 to Dec 2015. E. Coli Regulations: COMAR 26.08.04.02-1A(2). Discussion and Rationale(s): Brief description, if the fecal coliform limit is included in an approved TMDL. Total Residual Chlorine Regulations: COMAR 26.08.02.03-2G(1), COMAR 26.08.02.05C, COMAR 26.08.02.05D,COMAR 26.08.03.06C(5), COMAR 26.08.03.06D, COMAR 26.08.03.06F, Discussion and Rationale(s): The reasonable potential of the Lyons Creek WWTP effluent to cause a violation of the receiving stream's TRC water quality criteria was investigated to process the discharge permit renewal. An in-house SPREADSHEET program (developed by the Municipal Surface Discharge Permits Division) is used as a tool for the toxicity analysis. The toxicity based limit was compared with the effluent quality criteria to set the TRC limit requirement. Regulations: 40 CFR 130.7, COMAR 26.08.02.03-3A(4) pH Discussion and Rationale(s): The limits are set equal to the stream water quality criteria. Also, refer to Discussion and Additional Rationale for Total Ammonia Nitrogen as N. Dissolved Oxygen (DO) Regulations: COMAR 26.08.02.03-3A(4) Discussion and Rationale(s): The limits are set equal to the stream water quality criteria. Also, refer to Discussion and Additional Rationale forBOD5. Flow Regulations: COMAR 26.08.04.02A(2). The discharge is consistent with the (name of County) water and sewer master plan. SUMMARY REPORT & FACT SHEET (Application No. 12-DP-1275) Page No. 14 Outfall: 001A III. Proposed Effluent Limits and Monitoring Requirements Discussion and Rationale(s): The permit flow considered for this permit renewal is equivalent to the rated design capacity of the facility. It is not a limitation, but it incorporated with concentration limits to calculate the waste load limits for: BOD5, TSS, TP and TN}. Temperature Regulations: COMAR 26.08.02.03-3D(3) Discussion and Rationale(s): Refer to Section II "Special Condition and Requirements" for additional information pertaining to the temperature. WET Regulations: COMAR 26.08.03.07. Discussion and Rationale(s): Refer to Section II "Special Condition and Requirements" for additional information pertaining to the temperature. Additional Rationales for Effluent Limitations: (A) Anti-backsliding Policy Review: Provisions as stipulated in Federal Regulations [CWA 303(d)(4), CWA 402(o) & 40 CFR 122.44(l) require a reissued permit to be as stringent as the previous permit requirements, with some exceptions as determined be the Department. The effluent limitations established for the permit renewal are in conformance to the above stated provisions. (B) Anti-Degradation Policy Review: As outlined in COMAR 26.08.02.04 (Anti-degradation Policy), certain waters of the State possess an existing quality that is better than the water quality standards established for them. The quality of these waters shall be maintained: The discharge permit 12-DP-1275 being processed for the reissuance includes the effluent limitations which are sufficient to protect and maintain the water quality of the Lyons Creek. It does not require Tier II antidegradation review for the existing facility with permitted flow of 0.07 MGD. Rationale(s) for Monitoring Requirements: The Department Guidelines for Minimum Monitoring Requirements as revised by memorandums of 7/24/1996 and 3/6/2008. SUMMARY REPORT & FACT SHEET (Application No. 12-DP-1275) IV.

The treatment plant at the mobile home park is operated by Prostart Professionals. I met onsite with Bernard Williams and Deayo Betiku, operators representing Prostart Professionals. After preliminary introductory meeting I began the inspection reviewing the treatment plant operations at the wastewater treatment plant. The sky was sunny clear at the time of the inspection. Mr. Williams accompanied me during the site walk of the facility. The treatment plant is an activated sludge plant with aeration, clarifier, filtration, UV disinfection prior to discharge to tributary of the Patuxent River, designated as Use-I waters Inspection Date: Site Name: Facility Address: January 9, 2020 Lyons Creek Mobile Home Park WWTP 1007 Lower Pindell Rd, Lothian, MD 20711 which is protected for water contact and recreation and non-tidal warm water aquatic life. The clarifier effluent is pumped to UV disinfection and gravity fed to flow measuring box and discharge to tributary of Patuxent River. The following was observed during the site walk of the facility- 1. The wastewater from the mobile home park enters the treatment plant via gravity to manhole. On this date I observed cracks to the walls of the influent manhole and erosion around the manhole. Pictures are taken. Corrective Action: The influent manhole should be inspected for cracks and leaks and necessary repairs should be completed. The erosion near the manhole should be backfilled and repaired immediately. 2. On this date Mr. Williams stated the effluent pumps near the clarifier wetwell have failed which caused overflow from clarifier wetwell to backup into clarifier/aeration tank and which eventually overflowed out of the clarifier/aeration structure and overflowed on to the ground and gravity into tributary of Patuxent River. On this date Mr. Williams stated it was unclear at what time the effluent pumps failed and the overflow started. Mr. Williams stated the overflow was reported to the Department. Corrective Action: Submit a letter to the Department explaining when the overflow was notified to the Department via telephone and 5 day report was submitted to the Department. Submit a copy of the 5 day written report with the steps taken to prevent future overflows. 3. On this date Mr. Williams stated the clarifier effluent control system failed and pumps did not start when floats are activated. Mr. Williams stated the operator observed the overflow upon arrival onsite and operated the effluent pump manually to stop the overflow. On this date I observed dampness inside the clarifier/aeration tank structure. Pictures are taken. Corrective Action: Inspect the concrete wall around the aeration/clarifier tank for any leaks or cracks. Necessary repairs should be made to the concrete wall around the aeration/clarifier tank to prevent any leak or unauthorized discharge leaving the aeration/clarifier structure. 4. Mr. Williams stated the effluent pumps near clarifier were temporarily wired to operate the pumps. On this date I observed electricians onsite hard wiring all the wiring near the clarifier wet well. Mr. Williams stated the repairs will be complete by Monday. Corrective Action: Submit a letter to the Department indicating the electrical repairs at the clarifier effluent pumps. 5. Mr. Williams stated the treatment plant has mission's tele dial system to notify personnel during emergencies. Corrective Action: Submit a letter to the Department with the current mission system/telemetry dialing system onsite and which components are connected to the mission system and the working condition of the system. The letter should include whether the mission system/telemetry dialing system notified the operators of pump failure on the day of the event. 6. On this date I observed the facility did not have composite sampler onsite. Mr. Williams stated grab samples are collected for effluent analysis. Corrective Action: Permittee should start collecting 24hr composite samples immediately as required by the permit. Failing to comply with permit condition is considered as violation of the permit. 7. On this date I reviewed the monthly operating sheets (MOR) onsite. The review of MOR indicates no monthly effluent flow was reported for July, August and September 2019. Mr. Williams stated the final effluent totalizer was out of service and no final effluent flow was reported. Corrective Action: Submit a letter to the Department indicating (1) when the repairs to the flow totalizer was completed (2) how final effluent flow was reported (3) how the final effluent loadings are calculated.

On this date Mr. Williams stated the sand filter is bypassed in the treatment plant. Corrective Action: Notify the Department of the bypass of sand filters. Submit a letter to the Department what corrective action steps will be taken to bring sand filter online. 9. On this date I observed the skimmer arm to the clarifier was not working. On this date Mr. Williams stated the wastewater from clarifier leaks into wasting tank. On this date I observed portable pump is used to waste. Corrective Action: The structural integrity of the clarifier tank should be inspected, cracks and leaks should be repaired immediately. Necessary repairs should be made to the skimmer arm immediately. 10. On this date I observed the UV intensity panel was not working and it's unclear if the UV bulbs are in proper working condition. Pictures are taken. With respect to the above MDE NPDES Permit, violations of the Environmental Article, Title 9 were observed on this date: 1. Failed to operate the treatment to minimize upsets and unauthorized discharges as required by NPDES permit General Condition B-3"Facility Operation and Quality Control". 2. Failed to notify the Department of Bypass of Filter as required by NPDES permit General Condition B-5 "Bypassing". 3. Failed to calibrate the monitoring equipment as required by the NPDES permit General Condition A-5:" Monitoring Equipment Maintenance". 4. Failed to submit the Discharge Monitoring reports to the Department as required by permit General Condition A-2: "Monthly Monitoring Results". 5. Failed to collect composite samples as required by NPDES permit Special ConditionB (1) -Minimum Monitoring Requirement. To bring this site into compliance with Environmental Article Title 9, the following corrective action should be made immediately upon receipt of this report. 1. All the above mentioned corrective actions mentioned above should be corrected immediately. 2. The permittee should notify the Department via telephone within 24hrs followed by 5 day written report for the bypass of the sand filter. 3. Necessary repairs should be completed to the rotary drum filter and the filter should be brought online. 4. The UV intensity panel should be repaired and the UV intensity should be maintained as per manufacturer requirement. 5. DMRs should be submitted to the Department immediately. 6. The leak in the clarifier waste line should be repaired and necessary repairs should be completed to minimize the sludge blanket and scum buildup in the clarifier. Necessary repairs should be made to the clarifier skimmer arm. 7. Submit a letter to the Department explaining from which location grab samples for PH, DO and E.Coli samples are collected. Contact this inspector upon implementation of the requested corrective actions, reasonably necessary to bring the site into compliance. If the corrective actions cannot be completed within the prescribed time frames above, you should continue to advise this inspector, at least every 30 days, of the status of the measures taken to complete the corrective actions.
