 To amend the Safe Drinking Water Act to reduce lead in drinking water.

    Be it enacted by the Senate and House of Representatives of the 
United States of America in Congress assembled,
SECTION 1. SHORT TITLE.
    This Act may be cited as the ``Reduction of Lead in Drinking Water 
Act''.
SEC. 2. REDUCING LEAD IN DRINKING WATER.
    (a) In General.--Section 1417 of the Safe Drinking Water Act (42 
U.S.C. 300g-6) is amended--
        (1) by adding at the end of subsection (a) the following:
        ``(4) Exemptions.--The prohibitions in paragraphs (1) and (3) 
    shall not apply to--
            ``(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; or
            ``(B) toilets, bidets, urinals, fill valves, flushometer 
        valves, tub fillers, shower valves, service saddles, or water 
        distribution main gate valves that are 2 inches in diameter or 
        larger.''; and
        (2) by amending subsection (d) to read as follows:
    ``(d) Definition of Lead Free.--
        ``(1) In general.--For the purposes of this section, the term 
    `lead free' means--
            ``(A) not containing more than 0.2 percent lead when used 
        with respect to solder and flux; and
            ``(B) not more than a weighted average of 0.25 percent lead 
        when used with respect to the wetted surfaces of pipes, pipe 
        fittings, plumbing fittings, and fixtures.
        ``(2) Calculation.--The weighted average lead content of a 
    pipe, pipe fitting, plumbing fitting, or fixture shall be 
    calculated by using the following formula: For each wetted 
    component, the percentage of lead in the component shall be 
    multiplied by the ratio of the wetted surface area of that 
    component to the total wetted surface area of the entire product to 
    arrive at the weighted percentage of lead of the component. The 
    weighted percentage of lead of each wetted component shall be added 
    together, and the sum of these weighted percentages shall 
    constitute the weighted average lead content of the product. The 
    lead content of the material used to produce wetted components 
    shall be used to determine compliance with paragraph (1)(B). For 
    lead content of materials that are provided as a range, the maximum 
    content of the range shall be used.''.
    (b) Effective Date.--The provisions of subsections (a)(4) and (d) 
of section 1417 of the Safe Drinking Water Act, as added by this 
section, apply beginning on the day that is 36 months after the date of 
the enactment of this Act.

                               Speaker of the House of Representatives.

                            Vice President of the United States and    
                                               President of the Senate.
