Standardizing MS4 monitoring program for increased program effectiveness: Feasibility, challenges, and how to address them?

摘要

The Stormwater Monitoring Coalition (www.SoCaISMC.org) includes 14 members comprised of municipal stormwater permittees, plus the state and federal regulators that oversee them. The goal of this project is to create an inventory of current monitoring effort, compare and contrast similarities and differences among these monitoring programs, then provide a framework for a unified approach to stormwater monitoring (UASM) throughout southern California. The framework addresses seven monitoring questions held in common among all SMC Members: Q1. What pollutants are associated with stormwater and non-stormwater runoff? Q2. What are the sources of the identified pollutant(s)? Q3. How effective are the BMPs for reducing flow and contaminant concentrations? Q4. If (and how) runoff discharge is influencing the quality of receiving water? Q5. What is the overall health of receiving waters? Q6. If (and what) receiving waters need management actions based on its overall health? Q7. How effective are the current water quality management plans?
