Larsen, C.B.O., Director of Building and Housin~þ.-K6-J....- Secretary to the Board of Appeals and Advisors SUBJECT: Staff Report - Chlorinated Polyvinyl Chloride (CPVC) Water Pipe ---------------------------------------------- ---------------------------------------------- Recommendation: Recommend the Board approve the use of Chlorinated Polyvinyl Chloride (hereafter referred to as CPVC) water pipe for installation within buildings in the City of Chula Vista based on compliance with the following conditions: 1. Installation shall comply with all manufacturer's recommendations; and, 2. Installation shall comply with the 1994 Edition of the Uniform Plumbing Code; and, 3. Installation shall comply with the specific requirements contained in State Assembly Bill No. 151 (Baca); and, 4. Installation shall comply with the appropriate sections of the 1994 Uniform Building Code; and, 5. Authorization for new installations shall expire on January 1, 1998 as specified in AB 151. Introduction: The State of California recently approved Assembly Bill IS] (Baca) which repealed the existing restriction on the use of CPVc. As one of the conditions for authorizing use of CPVC, the Bill requires jurisdictions to take formal action to approve its use prior to January 1, 1996. Therefore, the Department is recommending the Board 'eview and approve the use of this material within the City of Chula Vista subject to the conditions identified above. Staff has reviewed the information available on the subject and feels it warrants approval for use. Much of that information is contained in the attached manufacturer's brochure. In making a decision to support use of this product, considerable weight was given to both 1 the product's physical characteristics and it's affordability. CPVC water pipe conforms to all applicable ASTM standards, is approved by all the national codes, is tested regularly and is certified by the National Sanitation Foundation for water purity. In addition, studies have shown that CPVC pipe is on the average 20% to 43% less costly to install than copper pipe. Staff believes the product will provide both good performance and meet the City's desire to be a leader in finding ways to enhance the affordability of new homes in the community. CPVC was originally approved for use within the City of Chula Vista when the 1979 Edition of the Uniform Plumbing Code was adopted. It's use continued to be authorized until the State of California amended the Code when it adopted the 1985 Edition of the Uniform Plumbing Code. While the Uniform Plumbing Code (published by the International Conference of Building Officials and used in approximately 2/3 of the United States) continued to authodze use of CPVC, the State of California's adoption of the UPC included an amendment forbidding the use of CVPC pending publication and adoption of an Environmental Impact Report (EIR). The EIR was intended to address potential dangers to public health and/or the environment that might arise from use of CPVC. The 1991 and 1994 Editions of the California State Plumbing Code also prohibited the use of CPVC water pipe pending final adoption of the EIR. This EIR has been published but it's final adoption has been challenged in court. Assembly Bill No. 151 (Baca) (Attachment # 1) and the letter signed by Governor Wilson on October 12, 1995 (Attachment # 2) establish the Legislature and Governor's reasons for approving the product at this time and sets forth the specific conditions that must be met to authorize use. The Legislature depended heavily on the experience gained by the City of Colton's Depa,-tment of Community Development. Confronted with widespread deterioration of copper piping systems due to the very corrosive nature of the soils in a tract in the western part of that city and acting pursuant to a good-faith belief that CPVC piping was in compliance with state regulations, the City of Colton approved the use as an alternative to copper piping in 1993. Starrs contacts with representatives of the City of Colton have revealed that installation in both new single family dwellings and the retrofitting of existing homes has proven very successful. As a result of this Bill, the City of Santa Ana, Madera County and San Joaquin County have already approved the use of CPVC pipe and other jurisdictions in San Diego County are currently considering such approval. ßWRJbwr (c:lwpSlladll1inlcpvcboa) ATTACHMENTS: I.

GOVERNOR'S OFFICE Octo~er 12, 1995 To the Members of the California Assembly. On this date I have signed Assembly Bill No. 15!. This bill permits the limited use of chlorinated polyvinyl chloride (CPVC) piping within buildings, providing such use is permitted by a local jurisdiction prior to January 1, 1996. This legislation affirms that iSlu.. involving the health and safety of con.truction standards and new building products should not be subject to environmental review. This bill takes into account not only numerous studies as to the safety of using plastic pipe for transporting potable water In residential dwelling., it acknowledges that the product is now being used in all other states in the nation. While thi. legislation affects limited jurisdictions in the stAte, I Am directing the Department of Housing and Community Development to propose adoption of emergency building standards and related regulations allowing the use of CPVC water piplng within residential dwellings statewida.
