Current Activities

Final Permit Issued: On Dec. 17, 2019, the department issued a final Missouri Hazardous Waste Management Facility Part I Permit for Safety-Kleen System's St. Charles facility, effective immediately. Any parties adversely affected or aggrieved by the department’s decision to issue the final Part I Permit, or specific conditions of the final Part I Permit, may be entitled to pursue an appeal before the Administrative Hearing Commission by filing a written petition by Jan. 16, 2020, as more fully described on page 5 of the final Part I Permit.

Safety-Kleen currently is operating and conducting corrective action investigations and remediation activities at the site under a department-issued Missouri Hazardous Waste Management Facility Part I Permit and U.S. Environmental Protection Agency (EPA)-issued Hazardous and Solid Waste Amendments Part II Permit. The status of Safety-Kleen’s corrective action activities is described below. On March 23, 2017, Safety-Kleen submitted a permit application to the department and EPA to renew and update their existing hazardous waste permits.

After a thorough technical review of the permit application and opportunity for public comment on the draft Part I Permit, the department issued a final Part I Permit. The final permit allows Safety-Kleen to continue managing and storing hazardous waste at the facility. EPA decided not to issue a Part II Permit, since EPA has no site-specific conditions for the facility, beyond those contained in the final Part I Permit, and Missouri is fully authorized for all permitting and corrective action activities at the facility. EPA will terminate the continued Part II Permit upon issuance of the final Part I Permit.

The public can review and copy paper copies of the final Part I Permit and supporting documents at the St. Charles City-County Library’s Kisker Road Branch, 1000 Kisker Road, St. Charles, Missouri (during normal business hours) or the agency locations above.

 

The Safety-Kleen Systems Inc. St. Charles facility is located on about 2 acres at 4526 Towne Court in St. Charles. Safety-Kleen operates a commercial hazardous waste storage facility at the site, which is part of a larger Safety-Kleen distribution/recycling network. This facility was designed to temporarily store spent solvents, paint wastes, lacquer thinner wastes and waste oil produced by Safety-Kleen’s customers. The majority of Safety-Kleen’s customers are small quantity hazardous waste generators such as automotive repair, industrial maintenance and dry cleaning businesses. The facility also stores other types of wastes on a 10-day transfer basis.

Safety-Kleen currently operates two hazardous waste container storage areas, with a combined maximum capacity of 6,466 gallons, and one 15,000-gallon hazardous waste storage tank. The hazardous waste is stored in containers and tanks until enough waste is collected to ship off-site to a Safety-Kleen recycling facility or contract reclaimer for processing. The reclaimed, or “cleaned”, solvent is then returned to Safety-Kleen’s customers as usable product.

According to applicable state and federal hazardous waste laws and regulations, all hazardous waste treatment, storage and disposal facilities are required to investigate and clean up releases of hazardous waste and hazardous constituents to the environment from their facility resulting from present and past hazardous waste handling practices. Investigation results show soil and groundwater beneath the facility contaminated with volatile organic compounds. Safety-Kleen has taken several measures to reduce unacceptable potential risks to human health and the environment. An enhanced bioremediation pilot test was put in place in 2004, with overall positive results. In May 2006, the department approved a full-scale enhanced bioremediation project. Safety-Kleen currently is monitoring the groundwater and planning additional enhanced bioremediation activities.

When EPA implemented the federal hazardous waste laws under the Resource Conservation and Recovery Act (RCRA) in 1980, all existing facilities that treated, stored or disposed hazardous waste in a way that would require a hazardous waste permit were required to notify EPA and apply for the permit or close those operations. Because of the large number of existing facilities, Congress set up requirements that allowed these facilities to operate temporarily under “interim status” until it received its permit. The Safety-Kleen St. Charles Service Center was granted interim status.

Safety-Kleen currently is operating and conducting corrective action investigations and remediation activities at the site under a department-issued Missouri Hazardous Waste Management Facility Part I Permit, effective Dec. 17, 2019. The Part I Permit was originally issued with an EPA-issued Hazardous and Solid Waste Amendments Part II Permit in 1993, and reissued in 2007. EPA decided not to reissue the Part II Permit in 2019, since EPA has no site-specific conditions for the facility and Missouri is fully authorized for all permitting and corrective action activities at the facility.

The Part I Permit allows Safety-Kleen to store hazardous waste in containers and tanks at its St. Charles facility. The permit also requires corrective action in the event there is a release of hazardous waste to the environment. The regulated units under the current permit consists of two hazardous waste container storage areas, with a combined maximum capacity of 6,466 gallons, and one 15,000-gallon hazardous waste storage tank. Used oil and usable product are not regulated under RCRA, and thus exempt from hazardous waste permitting requirements.
