Bioplant samples v VPDES requirements.xlsx

This file is a Discharge Monitoring Report (DMR) spreadsheet documenting compliance data for the Radford Army Ammunition Plant (RFAAP) Bioplant's Virginia Pollutant Discharge Elimination System (VPDES) permit VA0000248. The spreadsheet tracks monthly monitoring data from May 2025 through May 2026 for Outfall 029, recording flow rates, pH levels, and Biochemical Oxygen Demand (BOD5) measurements against permit limits established by the Virginia Department of Environmental Quality (VDEQ). Flow data is collected continuously using tire sensors, with measurements ranging from approximately 0.65 to 1.48 million gallons per day (MGD) average flows and maximum flows reaching up to 1.61 MGD. pH readings are recorded continuously using recording equipment, generally maintained within the 6.0 to 9.0 permit range, with most monthly averages falling between 7.2 and 8.3. BOD5 measurements are collected weekly as 24-hour composites, subject to a permit limit of 60 mg/L minimum and 120 mg/L maximum, with corresponding daily loading limits of 91.2 kg/day average and 243.6 kg/day maximum; one entry indicates an exceedance with a maximum of 68 mg/L and loads exceeding 68.6 kg/day average and 262.9 kg/day maximum.

This monitoring data directly supports the RFAAP Bioplant modernization project (Solicitation W519TC-26-R-BIOR), a pre-solicitation issued by the Department of the Army Materiel Command Contracting Command Rock Island Arsenal for design and construction of a new industrial wastewater treatment facility. The DMR data demonstrates the compliance challenges referenced in the pre-solicitation, which notes 14 permit violations across three incidents in 16 months, primarily related to inadequate BOD processing. The data establishes baseline performance metrics and regulatory requirements that the proposed modernized facility design must address to ensure consistent VPDES permit compliance and improved treatment of complex chemical wastewater streams containing solvents and propellant residues generated by RFAAP's ammunition manufacturing operations.
