CERCLA approved: Mid-Way Environmental Services, Inc.
The “Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as “Superfund”, was enacted by Congress on December 11, 1980. This law created a tax on the chemical and petroleum industries and provided broad Federal authority to respond directly to releases or threatened releases of hazardous substances that may endanger public health or the environment. Over five years, $1.6 billion was collected and the tax went to a trust fund for cleaning up abandoned or uncontrolled hazardous waste sites. The law authorizes two kinds of response actions:
- Short-term removals, where actions may be taken to address releases or threatened releases requiring prompt response.
- Long-term remedial response actions, that permanently and significantly reduce the dangers associated with releases or threats of releases of hazardous substances that are serious, but not immediately life threatening. These actions can be conducted only at sites listed on EPA’s National Priorities List .
MID-WAY ENVIRONMENTAL’S (CERCLA) ROLE:
The U.S. Environmental Protection Agency has determined that the Mid-Way Environmental Services facility (ODEQ ID # IW-NH-41001-OP), Stroud, Oklahoma, is acceptable for the receipt of hazardous substances, pollutants or contaminants [that are NOT Resource Conservation and Recovery Act (RCRA) hazardous waste] from Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) response actions.
This determination is made pursuant to the requirements prescribed in 40 CFR §300.440 (58 FR 49200, 49215 – 49218 September 22, 1993), and is based upon communication with representatives of the Oklahoma Department of Environmental Quality (ODEQ).
