42 U.S.C. § 6966a: Increased use of recovered mineral component in federally funded projects involving procurement of cement or concrete

the Secretary of Transportation; and the head of each other Federal agency that on a regular basis procures, or provides Federal funds to pay or assist in paying the cost of procuring, material for cement or concrete projects. involves the procurement of cement or concrete; and is carried out in whole or in part using Federal funds. ground granulated blast furnace slag other than lead slag; coal combustion fly ash; blast furnace slag aggregate other than lead slag aggregate; silica fume; and any other waste material or byproduct recovered or diverted from solid waste that the Administrator, in consultation with an agency head, determines should be treated as recovered mineral component under this section for use in cement or concrete projects paid for, in whole or in part, by the agency head. 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), may realize energy savings and environmental benefits attainable with substitution of recovered mineral component in cement used in cement or concrete projects. quantify the extent to which recovered mineral components are being substituted for Portland cement, particularly as a result of current procurement requirements, and the energy savings and environmental benefits associated with that substitution; identify all barriers in procurement requirements to greater realization of energy savings and environmental benefits, including barriers resulting from exceptions from current law; and identify potential mechanisms to achieve greater substitution of recovered mineral component in types of cement or concrete projects for which recovered mineral components historically have not been used or have been used only minimally; evaluate the feasibility of establishing guidelines or standards for optimized substitution rates of recovered mineral component in those cement or concrete projects; and identify any potential environmental or economic effects that may result from greater substitution of recovered mineral component in those cement or concrete projects. Not later than 30 months after August 10, 2005 , the Administrator shall submit to Congress a report on the study. realize more fully the energy savings and environmental benefits associated with increased substitution; and eliminate barriers identified under subsection (c). Nothing in this section affects the requirements of section 6962 of this title (including the guidelines and specifications for implementing those requirements).
