CA SB1065

Authorizes the State Water Resources Control Board to grant up to 3-year extensions beyond established compliance periods for public water systems to meet hexavalent chromium drinking water standards, effective until January 1, 2029.

Requires eligibility: public water systems must submit a compliance plan involving facility construction for treatment of over 10 water sources and demonstrate good faith efforts to meet applicable timelines.

Public water systems receiving extensions must comply with all state board requirements during the compliance period, including public notice requirements, and cannot be deemed in violation while implementing an approved compliance plan.

Allows the state board to implement and interpret these provisions through internet website guidance without following standard rulemaking procedures under the Administrative Procedure Act.

Specifies no state reimbursement is required for costs created by expanding criminal liability related to false statements in compliance plan submissions.
