As of June 2003, 38 states and 1 territory (Guam) are "authorized" by EPA to oversee cleanup at treatment, storage and disposal (TSD) facilities under RCRA's Corrective Action program. EPA's authorization is based on a determination that the State is capable of implementing a corrective action program equivalent to EPA's program. EPA regional offices have the lead responsibility for implementing corrective action in Indian Country and in states that have yet to be authorized. Furthermore, EPA often retains lead responsibilities when implementing corrective action under enforcement authorities of RCRA such as those included in RCRA §3008(h). However, EPA regions often share responsibilities with authorized as well as unauthorized states and Indian Country to maximize efficiencies with respect to achieving desired cleanup results. In general, EPA supports the variety of creative approaches EPA regions and states/Indian Country use to work together toward achieving corrective action goals.
You can refer to the Key Rule Status chart or the Corrective Action map to find out which states are authorized to implement the RCRA Corrective Action program. Also, you can obtain more information about EPA's regional offices as well as individual State Cleanup Programs by clicking EPA Regions or State Cleanup Programs.
