Overview

Summary

The purpose of this RFP/Q is to find a certified laboratory that will perform annual instream bioassessment testing on monitoring stations RSW-001U and RSW-002D as described and required per the facility's National Pollutant Discharge Elimination System (NPDES) permit. The results of these tests must be defensible, and all test procedures must follow the protocols established for the California Stream Bioassessment Procedure (CSBP) or more recently established sampling protocols, such as used by the Surface Water Ambient Monitoring Program (SWAMP) and be performed with trained staff and by laboratories that are either Environmental Laboratory Accreditation Program (ELAP) or National Environmental Laboratory Accreditation Council (NELAC) certified.

The selected service provider will be awarded a contract with a five-year term, July 1, 2025 through June 30, 2030.

Background

The City of Thousand Oaks is located in eastern Ventura County and consists of 56 square miles. The City population is approximately 122,000. The City is a general law city operating under the Council/Manager form of government. The City Council is comprised of five elected members through district-based elections, with one member serving as Mayor on an annual basis.

The City's Hill Canyon Treatment Plant (HCTP) is located at 9600 Santa Rosa Road, Camarillo, CA 93012. HCTP is a modern advanced tertiary treatment plant. HCTP is rated to treat up to 14 million gallons of wastewater per day.

The City's wastewater is generated from its domestic, commercial, and industrial customers. The water is treated to a tertiary level that is compliant with a wide variety of regulatory permits. By the time it is discharged into the creek, the water has undergone a process of screening, grit removal, clarification, aeration with nutrient removal, secondary clarification, multi-media filtration, and disinfection. The final effluent from the treatment plant is of high quality and is beneficially re-used for agricultural and landscaping irrigation.

HCTP, which discharges tertiary-treated effluent into a U.S. water body, must maintain an NPDES permit issued by the California Regional Water Quality Control Board, outlining the required effluent discharge standards.
