(ERG) (hereinafter, the EPA inspection team) conducted an announced Compliance Evaluation Inspection under Section 1445 of the Safe Drinking Water Act (SDWA), 42 U.S.C. 300j-4, of the City of Deer Park Public Water System (hereinafter, the System or Deer Park) (TX1010007). The inspection process began at approximately 8:30 AM on February 11, 2025 and finished at approximately 4:00 PM. Mariela Reyna and Janet Cherry presented their SDWA inspector credentials to System representatives during the opening conference. The EPA inspection team informed the System representatives that this was an EPA inspection to determine compliance with SDWA Section 1433, which requires community water systems that serve more than 3,300 people to complete a Risk and Resilience Assessment (RRA) and develop an Emergency Response Plan (ERP). The EPA inspection team also informed System representatives that they would be conducting a cybersecurity evaluation alongside the Section 1433 review. To facilitate the inspection process, the EPA inspection team used a checklist outlining the requirements of SDWA Section 1433 during the document review. Refer to Appendix 1, Opening and Closing Conference Sign-in Sheet. SYSTEM DESCRIPTION According to Drinking Water Watch, the System is owned by the City of Deer Park, serves a population of approximately 34,495 people, and has 14,156 service connections. It is a community water system as defined by 40 C.F.R., Part 141 Subpart A. The System purchases chloraminated water (no other treatment provided) from the City of Houston (TX1010013) through an agreement with City of Houston. The agreement allows for City of Deer Park to receive up to 7 million gallons per day (MGD). Current use by City of Deer Park is approximately 3.25 to 4 MGD. System staff communicate frequently with City of Houston staff on current and potential issues. The purchased chloraminated water is treated at the System's surface water treatment plant (referred to as the Deer Park SWTP in TCEQ's database; referred to hereafter as SWTP), where additional treatment is provided through coagulation, flocculation, sedimentation, filtration, and disinfection. The SWTP is able to treat up to 8 MGD. The System recently switched from chlorine gas to onsite chlorine generation. The treated water flows to a clearwell equipped with six booster pumps rated at 1,100 gallons per minute (gpm) that transfer the water to two 1-million-gallon (MG) ground storage tanks. Water is pumped to the distribution system by four pumps located near the two 1-MG ground storage tanks. The SWTP operates continuously and is staffed 24 hours per day. The System also has three emergency groundwater wells available if needed : x Well #2 (located at Plant 2 on P Street). x Well #3 (located at Plant 3 on Coy Street). This well is temporarily plugged and not available, but the System is rehabilitating this well. This site was not visited during the inspection. x Well #4 (located at Plant 4 on Pasadena Boulevard). 2 City of Deer Park (TX1010007) Inspection Date: February 11, 2025 These wells can be brought online if the SWTP is not able to meet demands, such as during fires, extreme drought, or cold weather. System staff periodically flush the wells and pump to waste. Refer to Appendix 2, City of Deer Park Water System Schematic for a drawing of the System that identifies the locations of assets and treatment processes. The System is equipped with a Supervisory Control and Data Acquisition (SCADA) system to monitor and control SWTP operations, pumps, and storage tank levels. System staff must be at the SWTP to view information or modify the SCADA settings. The System representatives stated they are responsible for the SWTP and wells; City of Deer Park maintenance staff are responsible for the distribution system. System representatives stated the maintenance staff perform hydrant flushing and valve exercising. System representatives stated the lead service line inventory information was submitted to TCEQ with lots of unknowns, but they did not identify any lead service lines to date. System representatives stated monitoring for total chlorine, monochloramine, and free ammonia is conducted every two weeks as part of the Nitrification Action Plan. Section II- INSPECTION ACTIVITY SUMMARY The EPA inspection team visited the SWTP, Plant 2, and Plant 4. Photographs taken during the site visits are presented in Appendix 3, Photograph Log. SWTP Site Visit The EPA inspection team walked through portions of the SWTP starting at 1:00 PM local time. The System has a laboratory certified for coliform analysis. The laboratory is also used to analyze total organic carbon, alkalinity, pH, and chlorine residual for process control purposes. Chemical storage is located at the SWTP, with all chemicals except polymer and phosphate delivered in bulk and stored onsite. The EPA inspection team observed that there was no secondary containment for spare chemical vats of sodium hypochlorite and LAS (Appendix 3, Photograph 1). All treated water flows to a clearwell and is transferred by pumps to two 1-MG storage tanks. The EPA inspection team observed that the air release valve discharge pipe on one of the transfer pumps was corroded (Appendix 3, Photograph 2). The EPA inspection team observed a gap on the flapper valve on the southern 1-MG ground storage tank (Appendix 3, Photograph 3). During the inspection, the operator readjusted the hinge on the flapper valve, resolving the gap. Both 1-MG storage tanks lacked locked ladder cages (Appendix 3, Photograph 4 and Photograph 5). Four high service pumps transfer water from the 1-MG storage tanks 3 City of Deer Park (TX1010007) Inspection Date: February 11, 2025 to the distribution system. The EPA inspection team observed a threaded sample tap with a hose on the high service pump discharge lines (Appendix 3, Photograph 6). The hose was attached to allow water to run and prevent freezing during the recent cold weather event. The SWTP is equipped with a diesel generator sufficiently sized to run all water treatment plant equipment and finished water pumps. System staff exercise the generator weekly and conduct a fullload test annually. The System also has a reserve tank of diesel and has a contractor that delivers it when needed. Plant 2 Site Visit The EPA inspection team arrived at Plant 2 at 2:05 PM local time. Plant 2 contains Well #2, gas chlorination, 1.0-MG ground storage tank, and two booster pumps that pump to distribution. There was no screen on the air release valve for Well #2 (Appendix 3, Photograph 7). The EPA inspection team felt corrosion on the well vent screen, but could not obtain a photo for documentation given the well vent screen location. The well sounding tube screen was torn and not completely intact (Appendix 3, Photograph 8). The EPA inspection team observed that the switch for the lights and ventilation system to the chlorine gas room is inside of the chlorine room. The chlorine gas sensor did not have a visual alarm. System staff exercise the diesel generator at Plant 2 weekly and conduct a full-load test annually. Plant 4 Site Visit The EPA inspection team arrived at Plant 4 at 2:25 PM local time. Plant 4 contains Well #4, gas chlorination, 1.0 MG ground storage tank (fed by the well), three booster pumps, and 0.5-MG elevated storage tank. Well #4 discharge piping has a threaded sample tap (Appendix 3, Photograph 9). The EPA inspection team observed that the overflow piping for the 1.0-MG ground storage tank is not secured to the slab (Appendix 3, Photograph 10). At the time of the inspection, the booster pump station had standing water on the floor due to a small leak from a booster pump discharge line. The sump under the booster pump station floor slab was almost full due to the leaking booster pump discharge line and water from the online chloramine analyzer (Appendix 3, Photograph 11 and Photograph 12). There was a threaded sample tap on the booster pump discharge line (Appendix 3, Photograph 13). The plant is equipped with a diesel generator.
