The Reduction of Lead in Drinking Water Act was enacted on January 4, 2011, to amend section 1417 of the Safe Drinking Water Act (SDWA or Act) respecting the use and introduction into commerce of lead pipes, plumbing fittings or fixtures, solder and flux. The 2011 "Reduction of Lead in Drinking Water Act" revised section 1417 to: (1) redefine "lead free" in SDWA section 1417(d) to (a) lower the maximum lead content of plumbing products such as pipes and fixtures from eight percent to 0.25 percent; (b) establish a statutory method for the calculation of lead content; and (c) eliminate the requirement that lead free products be in compliance with voluntary standards established in accordance with SDWA 1417(e) for leaching of lead from new plumbing fittings and fixtures; and (2) Create exemptions in SDWA section 1417(a)(4) from the prohibitions on the use or introduction into commerce for: (a) "pipes, pipe fittings, plumbing fittings or fixtures, including backflow preventers, that are used exclusively for nonpotable services such as manufacturing, industrial processing, irrigation, outdoor watering, or any other uses where the water is not anticipated to be used for human consumption" (SDWA 1417(a)(4)(A)); and (b) "toilets, bidets, urinals, fill valves, flushometer valves, tub fillers, shower valves, service saddles, or water distribution main-gate valves that are two inches in diameter or larger." (SDWA 1417(a)(4)(B)). The Community Fire Safety Act of 2013 further amended section 1417 of SDWA to exempt fire hydrants from the prohibitions on use and introduction into commerce of pipes, fittings, and fixtures that are not lead free. The EPA proposed regulations to assist in the implementation of these amendments to section 1417 of SDWA on January 17, 2017.
