Standard Regulations

Assembly Bill 434 (Statutes of 2015, Chapter 663, Garcia) amended and adopted Health and Safety Code (H&SC) Section 116380 and Section 116552.   

Pursuant to Health and Safety Code Section 116380, the State Water Board adopted emergency regulations pertaining to the use of POE and POU treatment. The emergency regulations have been effective since filing with the Secretary of State and remain in effect until January 1, 2018, or until the effective date of the adoption of standard regulations, whichever occurs first. It should be noted that the standard regulations are subject to the requirements of the APA.

The State Water Board is currently developing the standard POE and POU regulations to fulfill the statutory requirements. The standard regulations must be consistent with the use limits in H&SC Sections 116380 and 116552. The State Water Board expects the standard regulations to be consistent with the emergency regulations, but will consider revisions resulting from public comment period and knowledge gained from implementing the emergency regulations. The standard regulations include requirements from section 116380, which limits the use of POE and POU treatment to public water systems with fewer than 200 service connections, and Section 116552, which limits the use of POE and POU treatment to 3 years or until funding for centralized treatment is available (whichever occurs first).
