CA Health & Safety Code § 17921.7 (2021)
2021 California Code|Health and Safety Code - HSC|DIVISION 13 - HOUSING|PART 1.5 - REGULATION OF BUILDINGS USED FOR HUMAN HABITATION|CHAPTER 2 - Rules and Regulations|Section 17921.7.

17921.7.  (a)  (1)  The Legislature finds and declares all of the following: (A)  Acrylonitrile-butadiene-styrene (“ABS”) drain, waste, and vent plumbing pipe is used to drain or vent wastewater from kitchens, bathrooms, washers, and plumbing fixtures found in the home. ABS pipe is commonly used in residential construction, and ABS pipe has been installed in the foundations and walls of thousands of single-family homes, apartments, condominiums, and other residences throughout California. (B)  The American Society for Testing and Materials (ASTM) has established specifications for the manufacture of ABS pipe, including a requirement that ABS pipe be made from virgin plastic resin. These specifications have been incorporated into the Uniform Plumbing Code (UPC), which is applicable to all occupancies throughout the state pursuant to subdivision (b) of Section 18938, a provision of the California Building Standards Law (Part 2.5 (commencing with Section 18901)). (C)  ABS pipe that does not meet ASTM requirements might, within a period of a decade or less, crack and leak wastewater and sewage, resulting in structural damage, vermin infestation, and severe health hazards for residents or occupants of buildings in which defectively manufactured ABS pipe has failed. One apparent cause of these mechanical failures of ABS pipe has been the use of nonvirgin, reprocessed plastic resin for the manufacture of ABS pipe. (D)  The continued use of this nonvirgin, reprocessed plastic resin by some ABS pipe manufacturers violates the requirements of the UPC and is also in violation of the building standards established in accordance with the California Building Standards Law. The problem of the property damage inflicted on the public continues to worsen. (E)  Thousands of California residents either already have, or eventually will, experience serious damage to their homes, apartments, and condominiums, as well as threats to their health and safety, because of the substandard ABS pipe that has been installed, in violation of building standards, in structures throughout the state. (F)  There are currently no statutes or regulations that apply to the sale of defective plastic resin to ABS pipe manufacturers. (2)  It is, therefore, the intent of the Legislature that both of the following occur: (A)  That a provision that addresses the important issues set forth in paragraph (1) be added to the State Housing Law. (B)  That the Department of Housing and Community Development expeditiously implement the provisions of Chapter 413 of the Statutes of 1993 that relate to this section. (b)  On and after the effective date of the act that adds this section, no person shall sell or offer for sale a plastic resin for use in the manufacture of ABS DWV pipe that does not meet the requirements of the listing pursuant to authority granted by subdivision (e). (c)  (1)  Any and all plastic resin sold to an ABS DWV pipe manufacturer for use in ABS DWV pipe shall contain a certification that the plastic resin conforms to the requirements specified in the listing pursuant to subdivision (e). (2)  Any and all plastic resin sold to an ABS pipe manufacturer shall be accompanied by a document indicating the name and address of the manufacturer of that plastic resin, the date that the plastic resin was purchased by the seller, and specifications of the chemical and physical properties of the plastic resin. For a period of at least 10 years from the date of the sale of this plastic resin, the information required to be certified by this subdivision shall be kept onsite at the ABS pipe manufacturing plant, and available for inspection by the enforcement agency, at all times. (d)  No ABS DWV pipe that contains plastic resin that does not meet the requirements of the listing pursuant to subdivision (e) may be sold or offered for sale, or installed in any structure that is subject to this part. (e)  The listing agencies, as approved by the department, shall publish in each listing agreement with ABS DWV pipe manufacturers a list of ABS resins and resin compounds used by that manufacturer and approved for use by the listing agency. The approval of ABS resins and resin compounds shall be based on nationally recognized standards. The listing agencies shall consult with the affected parties. (Amended by Stats. 1997, Ch. 580, Sec. 4. Effective January 1, 1998.)
