(1) By January 1, 2013, and at least every three years thereafter, manufacturers of brake friction material sold or offered for sale in Washington state shall provide data to the department adequate to enable the department to determine concentrations of antimony, copper, nickel, and zinc and their compounds in brake friction material sold or offered for sale in Washington state.
(2) Using data provided pursuant to subsection (1) of this section and other data as needed, and in consultation with the brake friction material manufacturing industry, the department must:
(a) By July 1, 2013, establish baseline concentration levels for constituents identified in subsection (1) of this section in brake friction material; and
(b) Track progress toward reducing the use of copper and its compounds and ensure that concentration levels of antimony, nickel, or zinc and their compounds do not increase by more than fifty percent above baseline concentration levels.
(3) If concentration levels of antimony, nickel, or zinc and their compounds in brake friction material increase by more than fifty percent above baseline concentration levels, the department shall review scientific studies to determine the potential impact of the constituent on human health and the environment. If scientific studies demonstrate the need for controlling the use of the constituent in brake friction material, the department may consider recommending limits on concentration levels of the constituent in the material.
(4) Confidential business information otherwise protected under RCW 43.21A.160 or chapter 42.56 RCW is exempt from public disclosure.
