Dear Ms. Flaherty:
The Central Valley Clean Water Association (CVCWA) and the California Association of Sanitation Agencies (CASA) appreciate the opportunity to provide comments on the U.S. Environmental Protection Agency’s (USEPA) Draft Field-Based Methods for Developing Aquatic Life Criteria for Specific Conductivity (Draft Methods).1 CVCWA is a nonprofit association of publicly owned treatment works (POTWs) throughout the Central Valley of California whose primary mission is to represent wastewater agencies in regulatory matters while balancing environmental and economic interests. CVCWA members have a strong commitment to the protection of aquatic life in Central Valley waters. CASA is an association of local agencies engaged in advancing the recycling of wastewater into usable water and the generation of renewable energy and other valuable resources. Through these efforts we help create a clean and sustainable environment for Californians. Many of CVCWA’s and CASA’s members will be directly affected by the Draft Methods and therefore have a significant interest in their development and implementation.
