(a)  Except as provided in                 223.7304              and                 223.7305             , no contract may include a specification or standard that results in a deliverable or construction material containing more than 0.1 percent hexavalent chromium by weight in any homogeneous material in the deliverable or construction material where proven substitutes are available that provide acceptable performance for the application.          (b)  This prohibition is in addition to any imposed by the Clean Air Act regardless of the place of performance.223.7304 Exceptions.       The prohibition in                 223.7303              does not apply to—          (a)  Legacy systems and their related parts, subsystems, and components that already contain hexavalent chromium.  However, alternatives to hexavalent chromium shall be considered by the appropriate official during system modifications, follow-on procurements of legacy systems, or maintenance procedure updates; and          (b)  Additional sustainment related contracts (e.g., parts, services) for a system in which use of hexavalent chromium was previously approved.223.7305 Authorization and approval.       (a)  The prohibition in                 223.7303              does not apply to critical defense applications if no substitute can meet performance requirements.  The DoD policy of April 8, 2009, “Minimizing the Use of Hexavalent Chromium,” contains requirements for weighing hexavalent chromium versus substitutes.  DoD Program Managers must consider the following factors—          (1)  Cost effectiveness of alternative materials or processes;          (2)   Technical feasibility of alternative materials or processes;          (3)  Environment, safety, and occupational health risks associated with the use of the hexavalent chromium or substitute materials in each specific application;          (4)  Achieving a DoD Manufacturing Readiness Level of at least eight for any qualified alternative;          (5)  Materiel availability of hexavalent chromium and the proposed alternatives over the projected life span of the system; and          (6)  Corrosion performance difference of alternative materials or processes as determined by agency corrosion subject matter experts.          (b)  However, unless an exception in                 223.7304              applies, the incorporation of hexavalent chromium in items acquired by DoD shall be specifically authorized at a level no lower than a general or flag officer or a member of the Senior Executive Service from the Program Executive Office or equivalent level, in coordination with the component Corrosion Control and Prevention Executive.  Follow the procedures in PGI                 223.7305             .223.7306 Contract clause.       Unless an exception in 223.7304 applies, or use has been authorized in accordance with 223.7305 , use the clause at 252.223-7008 , Prohibition of Hexavalent Chromium, in solicitations and contracts, including solicitations and contracts using FAR part 12 procedures for the acquisition of commercial products and commercial services, that are for supplies, maintenance and repair services, or construction.Subpart 223.74 - PROHIBITION ON PROCUREMENT OF CERTAIN ITEMS CONTAINING PERFLUOROALKYL OR POLYFLUOROALKYL SUBSTANCES   223.7400 Scope of subpart.       This subpart implements section 322(b), (c), and (d) of the National Defense Authorization Act for Fiscal Year 2020 (Pub. L. 116-92).    223.7401 Definition.       As used in this subpart—          “Ocean-going vessel” means a vessel over 59 feet in length owned or operated by DoD or the U.S. Coast Guard, other than vessels that are chartered by the Armed Forces on a time or voyage basis.223.7402 Prohibition.       After October 1, 2023, do not procure aqueous film-forming foam, which is used for fighting fires, that contains in excess of one part per billion perfluoroalkyl substances or polyfluoroalkyl substances. Procurements of fire-fighting agent for use solely onboard ocean-going vessels are exempt from this prohibition.223.7403 Procedures.After October 1, 2023, contracting officers shall only issue a solicitation to procure fire-fighting agent in accordance with performance specification MIL-PRF-24385F(SH), unless the requiring activity provides documentation of the exemption at 223.7402. The contracting officer shall maintain the documentation in the contract file.223.7404 Contract clause.Use the clause at 252.223-7009, Prohibition of Procurement of Fluorinated Aqueous Film-Forming Foam Fire-Fighting Agent for Use on Military Installations, in solicitations and contracts, including solicitations and contracts using FAR part 12 procedures for the acquisition of commercial products and commercial services, relating to fire-fighting on military installations.
