The FFCO requires compliance with the Site Treatment Plan (STP) Compliance Plan Volume (CPV) for the treatment and disposal of mixed waste at Los Alamos National Laboratory (LANL). The Respondents must comply with the New Mexico Hazardous Waste Act, Sections 74-4-1 to -14 and Section 3012(b) of RCRA, 42 U.S.C. §6939(c), as amended by the FFCA of 1992, Public Law 102-386, 106 Stat. 1505 (1992).  In accordance with Section X, “Revisions” of the FFCO, all proposed or required revisions shall be made available to the public for review at appropriate locations.
