Topic: State Water Resource Control Board’s Cost Estimates in Consideration of a Hexavalent Chromium Maximum Contaminant Level (MCL) White Paper.
Thank you to all who helped CalMutuals take action with the State Water Resources Control Board to bring potential issues regarding the Hexavalent Chromium cost estimates to the forefront of discussion.
Summary: CalMutuals has the position that the State Water Resources Control Board’s current cost estimates may not reflect true economic feasibility and still retain problems that may prevent it from being legally acceptable. The discussion of the allowance of alternative technologies such as POE/POU devices, modelling strategies for predictions, and universal treatment assumption concerns support CalMutuals’ position that more consideration must be given to all systems as well as their costs and abilities before moving forward.
If you would like to follow the evolution of this issue you may read our previous comment letter to the State Water Resources Control Board regarding their economic feasibility analysis dating back to April 2020 that summarizes CalMutuals’ position that the White Paper does not adequately address the issues cited by the Courtin invalidating the previous standard for hexavalent chromium.
Bill of Interest:
AB 588 (E. Garcia) California Environmental Quality Act: Small Community Water System; Exemption
Summary: CalMutuals worked in support of Assemblymember Garcia to garner state wide support for AB588; which, if enacted, would institute a planned compliance period for water systems to meet new drinking water regulations. For small water systems the existing time to comply can leave them scrambling for a solution.
