The Missouri Department of Natural Resources issued a final Missouri Hazardous Waste Management Facility Part I Permit for the Missouri Pressed Metals Inc. facility. These permits require the company to continue performing post-closure and corrective action activities at its Sedalia facility.
Please be aware that any parties adversely affected or aggrieved by the department’s decision to issue the final Part I Permit, or specific conditions of the Part I Permit, may be entitled to pursue an appeal before the Administrative Hearing Commission by filing a written petition by June 27, 2025, as more fully described on page 6 of the final Part I Permit.
The Missouri Pressed Metals Inc. facility is located at 1200 E. Boonville Rd. in Sedalia, Missouri. Since 1973, Missouri Pressed Metals has operated a specialty manufacturing company at the site, producing bushings and bearings of sintered metal. Until 1995, raw 1,1,1-trichloroethane (TCA) was used in the vapor degreaser. Between 1973 and 1985, spent 1,1,1-TCA/ waste oil was used as a herbicide along the east and north sides of the building for weed control. Initial investigations confirmed the soil and groundwater were contaminated with 1,1,1-TCA and related compounds. The Missouri Department of Natural Resources designated this area as a regulated hazardous waste land disposal unit. The department accepted Missouri Pressed Metals' closure certification for the unit in 1997; however, Missouri Pressed Metals is subject to the permitting requirements of the Missouri Hazardous Waste Management Law and federal Hazardous and Solid Waste Amendments for post-closure care because hazardous waste remained in place after closure.
Missouri Pressed Metals has been conducting post-closure and corrective action activities at the site under a department-issued Missouri Hazardous Waste Management Facility Part I Permit. On Sept. 14, 2023, Missouri Press Metals submitted a permit application to the department to renew and update its hazardous waste permit. After a thorough technical review of the permit application and opportunity for public comment on the draft permit, the department issued a final Part 1 Permit. The final permit requires Missouri Pressed Metals to continue operating a groundwater extraction system and monitoring the groundwater.
