1154324 02/05/2026 Deficient Monitoring On February 5, 2026, the autosampler for INF-001 (NORS) did not collect samples between 0100 and 0500 due to maintenance activities in the surrounding area lifting the sample line above influent flow. Manual collection of samples began afterwards, but requirements for a 24-hour composite sample were not met. Monitoring of biochemical oxygen demand and total suspended solids is a daily requirement and were missed due to this sampling issue. Violation N eSMR Hyperion WWTP 447793 R4-2023-0033 N
1153148 01/21/2026 Deficient Monitoring On January 21, 2026, the autosampler for INF-001 (NORS) went offline between 01:00 and 15:00. No manual grabs were collected, so there was no representative composite sample to analyze and, therefore, there are no results for neither biochemical oxygen demand nor total suspended solids. Violation N eSMR Hyperion WWTP 447793 R4-2023-0033 N
1152332 12/31/2025 Deficient Monitoring There was an emergency shutdown of LAGWRP on December 2, 2025 due to a homicide investigation. There was no discharge of effluent from December 3 to December 22. LAGWRP started discharging effluent on the afternoon of December 23. Due to the emergency shutdown of LAGWRP, there was two deficiency violations; one for the influent and one for the effluent. Some of the daily requirements, weekly requirements, and a monthly requirement were missed. There were two weekly requirements missed for the week of November 30th, and some daily requirements were missed on December 1st, 2nd and 23rd.

1150397 10/03/2025 Deficient Monitoring There was one monitoring deficiency for the HWRP daily permit requirements. EFF-001, INF-001, INF-002, INF-003, INF-004, and INF-005 collected on October 3, 2025 failed QC requirements for biochemical oxygen demand (BOD). The failure was due to dissolved oxygen depletion to below 1 mg/L, resulting in a result of AE for all six samples. The failure was attributed to contamination in the reagent water, likely due to new tubing that was not decontaminated prior to use. Violation N eSMR Hyperion WWTP 447793 R4-2023-0033 N

1149317 08/14/2025 Deficient Monitoring On August 14 2025, the autosampler for INF-001 (NORS) failed, therefore no representative composite samples was collected. There are no results for biochemical oxygen demand nor total suspended solids. As of August 16, operations has resolved the autosampler issues. Violation N eSMR Hyperion WWTP 447793 R4-2023-0033 N
1149316 08/23/2025 Deficient Monitoring There was one monitoring deficiency for the HWRP weekly permit requirements. On August 23, 2025, the samples collected for oil and grease were not properly preserved and therefore, there are no oil and grease results for EFF-002, INF-001, INF-002, INF-003, INF-004, and INF-005. To avoid this issue in the future, the staff was retrained on proper preservation procedures for the analytical method. Violation N eSMR Hyperion WWTP 447793 R4-2023-0033 N
1149315 08/12/2025 Deficient Monitoring On August 12 2025, the autosampler for INF-001 (NORS) failed, therefore no representative composite samples was collected.

1149312 08/31/2025 CTOX Chronic Toxicity Monthly Median limit is 0 Pass/Fail (Pass = 0, Fail = 1) and reported value was 1 Pass/Fail (Pass = 0, Fail = 1) at EFF-001A. Violation N eSMR Donald C. Tillman WWRP 447892 R4-2022-0341 N
1148226 07/24/2025 Deficient Monitoring Maintenance was being conducted on the associated devices that record the flow data for the DCTWRP influent on July 24, 2025. Due to that, the influent flow data that was recorded was not accurate. The influent flow is a continuous monitoring requirement reported on a daily basis for the daily average flow and daily maximum flow. The total daily flow for the influent on July 24, 2025 will be reported as an instrument failure (IF). This resulted in one deficient monitoring violation for July 2025. Violation N eSMR Donald C. Tillman WWRP 447892 R4-2022-0341 N
1148189 07/27/2025 Deficient Monitoring On August 2, 2025, the analytical batch containing EFF-001, INF-001, INF-002, INF-003, INF-004, and INF-005, all collected on July 27, 2025, failed QC requirements for biochemical oxygen demand (BOD). The failure was due to a dissolved oxygen depletion below 1 mg/L after five days. Violation N eSMR Hyperion WWTP 447793 R4-2023-0033 N
1147170 06/28/2025 Deficient Monitoring On 6/28/25, the autosampler at INF-004 failed and no sample was collected. Because there was no composite sample, daily BOD and TSS could not be analyzed therefore resulting in a monitoring deficiency. Violation N eSMR Hyperion WWTP 447793 R4-2023-0033 N
1147166 06/02/2025 CTOX Chronic Toxicity Maximum Daily (MDEL) limit is 0 Pass/Fail (Pass = 0, Fail = 1) and reported value was 1 Pass/Fail (Pass = 0, Fail = 1) at EFF-001A. Violation N eSMR Donald C. Tillman WWRP 447892 R4-2022-0341 N
