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.
