NPDES Sampling Evaluation Raymond POTW (Permit No. MS0051772)
1. Introduction
On March 29-30, 2022, representatives of the U.S. Environmental Protection Agency (U.S. EPA) Region 4 Laboratory Services and Applied Science Division (LSASD) conducted a National Pollutant Discharge Elimination System (NPDES) Reconnaissance Sampling Evaluation at Raymond Publicly Owned Treatment Works (POTW) in Raymond, Mississippi. The evaluation was requested by the ECAD Water Enforcement Branch as part of the agency's goal to address significant non-compliance (SNC) facilities. A 24-hr composite sample was collected and analyzed for Total Suspended Solids (TSS), Ammonia (NH3), Total Phosphorus (P) and Biochemical Oxygen Demand (BOD5), listed on the issued NPDES Permit MS0051772 as well for Total Kjeldahl Nitrogen (TKN), and Nitrate/Nitrite as N. TKN and Nitrate/Nitrite were collected to calculate the Total Nitrogen (N) parameter listed on the permit. The inspection followed the procedures listed in the LSASD Project No. 22-00181-0183 Sample and Analysis Plan (SAP). Table 1 lists the sampling participants.

2. Summary
Analytical results for BOD5 and NH3 from the 24-hour composite effluent discharge sample EFF001 exceeded the NPDES permitted limits. The result for TSS were within the permitted limit and Total Nitrogen and Phosphorus have report only requirements.
The wastewater treatment system consists of an activated sludge basin with mechanical aerators and a rectangular clarifier. Chlorine disinfection is added in the rectangular contact chamber before the effluent is discharged.
LSASD Project: 22-0182
Page 4 of 7 NPDES Recon Sampling Evaluation Final Report
3. Sample Analysis Results
Following the permit, a 24-hr time based composite sample was collected at EFF001. The sample collected at EFF001 was collected after final chlorine disinfection in the rectangular discharge box. The analytical results were all within the permitted limits for TSS, pH, and Dissolved Oxygen. The results for BOD5 and NH3 as N were above the permitted limits highlighted below.

* U The analyte was not detected at or above the reporting limit. * H-6 Sample originally analyzed within holding time; some QC requirements not met. The reported result is from a second analysis performed for confirmation which occurred after the holding time expired. * QM-2 Matrix Spike Recovery greater than method control limits. * QM-4 Matrix Precision outside method control limits. * J The identification of the analyte is acceptable; the reported value is an estimate. * A The analyte was analyzed in replicate. Reported value is an average value of the replicates.

Attached are the final results for the analytical groups listed below. This report shall not be reproduced except in full without approval of the Region 4 laboratory. These analyses were performed in accordance with the Laboratory Services Branch's Laboratory Operations and Quality Assurance Manual (LSB LOQAM) found at www.epa.gov/region4/sesd/asbsop. Any unique project data quality objectives specified in writing by the data requestor have also been incorporated into the data unless otherwise noted in the Report Narrative. Chemistry data have been verified based on the LSB LOQAM specifications and have been qualified by this laboratory if the applicable quality control criteria were not met. Verification is defined in Chapter 5 of the LSB LOQAM. For a listing of specific data qualifiers and explanations, please refer to the Data Qualifier Definitions included in this report. The reported results are accurate within the limits of the method(s) and are representative only of the samples as received by the laboratory.

Notes and Definitions for QC Samples
The analyte was not detected at or above the reporting limit. MRL verification for Non-Potable Water matrix Matrix Spike Recovery greater than method control limits Matrix Precision outside method control limits MRL verification recovery greater than upper control limits. Sample background/spike ratio higher than method evaluation criteria
