BACKGROUND

Orange County Sanitation District's (OC San) 2021 National Pollutant Discharge Elimination System (NPDES) Permit requires an updated Technical Evaluation of Local Limits (TELL) to establish local discharge limitations (Local Limits) for pollutants that could affect the integrity of the collection system, treatment plant and water reclamation operations, or endanger the safety of sewer workers and the public. The TELL requires extensive sample collection and analysis throughout OC San's service area and treatment system to determine pollutants of concern and Local Limits. The updated Local Limits must be based on sound scientific and engineering principles and will undergo review by the federal, state, and local regulatory agencies as well as other stakeholders, such as industrial dischargers and the public.

OC San advertised for proposals on March 6, 2025. A proposal was received from one firm on April 17, 2025 and was evaluated in accordance with OC San's policies and procedures. The proposal received from EEC Environmental was deemed the proposal of best value in terms of meeting OC San' s project requirements. Staff recommend awarding a Professional Consultant Services Agreement to EEC Environmental for Technical Evaluation for Local Limits Development, Specification No. CS-2025-666BD for a total amount not to exceed $459,840.
