Dear Ms. Webster:

Robertson-Bryan, Inc. (RBI) is pleased to present this proposal to provide services to conduct an environmental DNA (eDNA) pilot study to evaluate the efficacy of using eDNA to make defensible presence/absence determinations regarding freshwater mussels in POTW’s receiving waters. This work would be conducted as “Phase IIa” of the Freshwater Mussel Collaborative Study for Wastewater Treatment Plants. As you know, Phase I examined the current state of knowledge regarding freshwater mussels in water bodies of the Central Valley, identified the field methods for determining if mussels are present or absent in a water body, and provided guidance on the regulatory options for compliance with the U.S. Environmental Protection Agency’s (USEPA) 2013 ammonia criteria.

Dear Ms. Luo:
The Central Valley Clean Water Association (CVCWA) appreciates the opportunity to comment on the Notice of California Environmental Quality Act Scoping for Evaluation of Ammonia Water Quality Criteria for the Protection of Aquatic Life in the Central Valley (Ammonia CEQA Scoping). CVCWA is a non-profit association of public agencies located within the Central Valley region that provide wastewater collection, treatment, and water recycling services to millions of Central Valley residents and businesses. We approach these matters with the perspective of balancing environmental and economic interests consistent with state and federal law. In this letter, we provide brief comments regarding the Central Valley Regional Water Quality Control Board’s (Central Valley Water Board) proposed project to consider whether numeric water quality objectives for ammonia should be adopted into the Board’s Water Quality Control Plans.

Dear Mr. Kirn:
The Central Valley Clean Water Association (CVCWA) appreciates the opportunity to submit these comments on the Tentative Order for El Dorado Irrigation District’s (EID) El Dorado Hills Wastewater Treatment Plant (WWTP). CVCWA is a non-profit organization representing more than 50 publicly owned treatment works (POTWs) throughout the Central Valley in regulatory matters affecting surface water discharge, land application, and water reuse. We approach these matters in a way that balances environmental and economic interests consistent with applicable law.
