Comparison: State vs. Federal
• Rules. Montana has adopted by reference the federal land disposal restrictions (LDRs) that were in effect as of July 1, 2008, including the Phase IV federal LDRs and best demonstrated available technology (BDAT). Montana, however, has not adopted the following federal LDRs because EPA has not delegated authority to states to implement these rules (ARM 17.53.1102(1)):
—Case-by-case extensions (40 CFR 268.5)
—No-migration variances (40 CFR 268.6)
—Equivalent method variances (40 CFR 268.42(b))
—Variances from treatment standards (40 CFR 268.44)
See LDR Exceptions in the national section LAND DISPOSAL RESTRICTIONS/LAND BAN for more information about these extensions and variances.
• Administration and enforcement. Montana's hazardous waste management program is authorized by EPA and administered and enforced by DEQ's Waste and Underground Tank Management Bureau. However, when new LDRs are issued under the Resource Conservation and Recovery Act's (RCRA) Hazardous and Solid Waste Amendments (HSWA), EPA will administer the new regulations until equivalent or more stringent rules are adopted by the state.
