Storm Water Quality Webinar Series (6/16/2026) - Industrial Stormwater & TMDLs

This webinar hosted by the City of Oklahoma City on June 16, 2026, focused on industrial stormwater permitting and compliance with Total Maximum Daily Loads (TMDLs) under the Oklahoma multi-sector general permit (OKR05 MSGP). The presentation, led by Nathan Collier from WSP, covered regulatory requirements for industrial stormwater discharges, the identification and management of impaired waters, and the implications of TMDLs for industrial facilities. Specific examples highlighted compliance challenges such as pollutant exposure from metals, bacteria, and PCBs, and the importance of updating stormwater pollution prevention plans (SWPPPs) to address new impairments and TMDL requirements. The session emphasized the need for ongoing monitoring, documentation, and corrective actions to maintain permit compliance and avoid potential enforcement actions, including the need for individual permits in some cases. No direct contract awards or procurement decisions were discussed, but the content is relevant for industrial facilities managing stormwater compliance and environmental consulting services.
