The Water Quality Control Commission adopted the federally mandated Lead and Copper Rule Revisions to maintain primacy as well as revisions to Colorado-specific requirements for backflow prevention and cross-connection control. See https://www.sos.state.co.us/CCR/RegisterPdfContents.do?publicationDay=09/25/
2023 (pp. 1251-1393).

The Colorado Water Quality Control Commission proposed to amend 5 Colo. Code Regs. §1002-11, the primary drinking water regulations. The amendments would require inspections of water storage tanks twice per year, establish surveying requirements for non-single-family-residential connections to the public water system for cross-connections to prevent backflow, and amend the due dates within the rule for achieving 100% survey completion of the distribution system and 90% assembly testing. A hearing will be held August 10, 2020. Comments are due July 29, 2020.

The Division of Drinking Water proposed amendments to Utah Admin. Code r. 309-105-12. The proposed amendments would update reference to the International Plumbing Code, make specific requirements for cross-connection control programs to have trained staff, and change terminology to be accurate. Comments are due October 31, 2018. See https://rules.utah.gov/publicat/bull_pdf/2018/b20181001.pdf (pp. 34-38).
