Description

The services provided include surface water, sediment, and fish tissue sampling in streams and large river systems, as well as ambient sediment toxicity testing to determine the effectiveness of corrective measures. Acute and chronic whole effluent toxicity testing is conducted for four NPDES permitted outfalls, with the capability to perform Toxicity Identification Evaluation and Toxicity Reduction Evaluation if needed. Additionally, statistical analysis is compiled and conducted for three RCRA Detection monitoring groundwater assessment reports (covering three regulated units) and twelve RCRA Corrective Action Closure sites annually. Maintenance and updating of the PBA-specific Geographic Information System database is also included. The services encompass preparing industrial stormwater permit renewals, Stormwater Pollution Prevention Plans, and stormwater sampling for three outfalls, as well as preparation of Construction SWPPPs and permits. Compliance assistance is provided for SPCC Plan development and review, RCRA Permit development and review, and CAA permit review, renewal, and reporting. The services also support a change of the State of Arkansas Water Quality Standards, Rule 2, for mercury at an NPDES outfall, and assist with contaminant transport investigations in Phillips Creek and the Arkansas River. *Amendment 0001 posted 12 November 2026
