Coordinated Integrated Monitoring Program

The County of Los Angeles entered into an agreement with the Los Angeles County Flood Control District, and the cities of Los Angeles and Culver City for the development of a Coordinated Integrated Monitoring Program (CIMP). The CIMP is required by the Los Angeles Regional Water Quality Control Board National Pollution Discharge Elimination System Municipal Separate Storm Sewer System Permit (MS4 Permit) which was adopted on December 28, 2012. The goal of the CIMP is to conduct water quality monitoring at receiving water and stormwater outfall locations (see image below) to:

  1. Assess the chemical, physical, and biological impacts of discharges from the MS4 on receiving waters.
  2. Assess compliance with receiving water limitations and water quality-based effluent limitations established to implement Total Maximum Daily Load wet weather and dry weather waste load allocations.
  3. Characterize pollutant loads in MS4 discharges.
  4. Identify sources of pollutants in MS4 discharges.
  5. Measure and improve the effectiveness of pollutant controls implemented under the MS4 Permit.

Copies of the draft and final versions of the CIMP can be found on the Los Angeles Regional Water Quality Control Board’s website for the Marina del Rey Watershed Management Group.
