42 U.S. Code § 6966a - Increased use of recovered mineral component in federally funded projects involving procurement of cement or concrete
Not later than 1 year after August 10, 2005, the Administrator and each agency head shall take such actions as are necessary to implement fully all procurement requirements and incentives in effect as of August 10, 2005 (including guidelines under section 6962 of this title) that provide for the use of cement and concrete incorporating recovered mineral component in cement or concrete projects.
In carrying out paragraph (1) an agency head shall give priority to achieving greater use of recovered mineral component in cement or concrete projects for which recovered mineral components historically have not been used or have been used only minimally.
The Administrator and each agency head shall carry out this subsection in accordance with section 6962 of this title.
The Administrator, in cooperation with the Secretary of Transportation and the Secretary of Energy, shall conduct a study to determine the extent to which current procurement requirements, when fully implemented in accordance with subsection (b) of this section, may realize energy savings and environmental benefits attainable with substitution of recovered mineral component in cement used in cement or concrete projects.
Nothing in this section affects the requirements of section 6962 of this title (including the guidelines and specifications for implementing those requirements).
