1,2,3-Trichloropropane Maximum Contaminant Level

Dear Ms. Townsend:
The Central Valley Clean Water Association (CVCWA) appreciates this opportunity to provide comments on the Proposed Rulemaking for 1,2,3- Trichloropropane Maximum Contaminant Level. CVWA 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 municipal and domestic beneficial uses in Central Valley waters. The Proposed Rulemaking will inadvertently impact POTWs because maximum contaminant levels (MCLs), once adopted, become water quality objectives per incorporation by reference language in the Central Valley Water Quality Control Plans. Accordingly, it is imperative that the Division of Drinking Water consider such impacts when it adopts MCLs. CVCWA provides the following comments on the Proposed Rulemaking because of this impact.
