    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

    [[Page 4132]]

    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.
