Dow Midland Plant and Salzburg Landfill Hazardous Waste Management Facility Operating License Information
The Dow Chemical Company (Dow), Michigan Operations, Midland Plant is a chemical manufacturing complex located at 1790 Building, Washington Street, Midland, Michigan, and the Dow, Michigan Operations, Salzburg Road Landfill is a hazardous waste landfill located at 2314 West Salzburg Road, Midland, Michigan.
The combined Midland Plant and Salzburg Road Landfill complex is comprised of approximately 2,052 acres. Dow manufactures a variety of chemical products using a variety of process equipment including reactors, distillation/fractionation columns, separators, storage tanks/silos, boilers, condensers, thermal heat recovery, oxidation units, scrubbers, etc. at various locations within the Dow Chemical Complex. Many locations across the complex generate hazardous waste which Dow is licensed to store, treat, and dispose of under the hazardous waste license issued by the Michigan Department of Environment, Great Lakes, and Energy (EGLE), Materials Management Division (MMD).
Dow's license covers its hazardous waste container storage, tank storage and treatment, surface impoundment storage and treatment, incinerator, and on-site and off-site clean-up (corrective action) activities. Dow's license also covers the Salzburg Road Landfill located southwest of the intersection of Waldo and Salzburg Roads. Dow also has separate air and wastewater permits, and a separate solid waste landfill permit and license for other operations occurring within the complex.
Part 111, Hazardous Waste Management, of Michigan's Natural Resources and Environmental Protection Act, 1994 PA 451, as amended (NREPA), and the administrative rules promulgated thereunder, and the federal Resource Conservation and Recovery Act of 1976, as amended, RCRA, and the corresponding regulations, identify the standards that must be met when handling hazardous waste from generation to disposal. These regulations specify how the facility must operate to protect human health and the environment. They also identify the authorities EGLE has in licensing and overseeing hazardous waste operations.
Hazardous waste laws and regulations
The hazardous waste laws and supporting regulations provide enforceable standards for the treatment, storage, and disposal of hazardous waste. They also require tracking of hazardous waste from the generator and transporter to the disposal facility to ensure proper management and disposal that is protective of human health and the environment. To maintain groundwater quality, most hazardous waste is restricted from land disposal unless pre-treated.
The hazardous waste statute and rules that prescribe TSDF licensing standards include:
- Part 111, Hazardous Waste Management, of the Michigan Natural Resources and Environmental Protection Act, 1994 PA 451, as amended, and the administrative rules promulgated thereunder.
- The corresponding statutory provisions of the federal Resource Conservation and Recovery Act of 1976 (RCRA), as amended by the Hazardous and Solid Waste Amendments of 1984 (HSWA), and its rules.
How this facility is regulated
The facility is subject to multiple environmental regulatory programs, carried out by multiple government agencies. Each agency issues separate permits or licenses under the authority they are assigned under the regulations. The permit or license issued by each agency identifies what Dow must do to operate properly, to prevent the release of contaminants to the environment, and to limit any allowed discharge of contaminants to levels determined to be protective of human health and the environment. Each agency requires monitoring and performs independent oversight to ensure the facility is operated in a protective manner that meets the permits and license requirements. The agencies also share information to ensure compliance.
State requirements
EGLE, MMD licenses and inspects Dow's hazardous waste and solid waste operations separately. The MMD inspects Dow's hazardous waste operations at least four times per year and solid waste operations at least once per year. These inspections are typically unannounced. The inspections are performed to verify the operations meet the license requirements. The MMD evaluates Dow's hazardous waste storage, treatment, and disposal areas, emergency planning, employee training, record keeping, and corrective action (clean-up) information. For further information on MMD inspections, contact Todd Zynda, Environmental Engineer Specialist, Warren District Office, MMD.
EGLE, Air Quality Division (AQD), issues the permit for air emissions from the facility. The AQD inspects the facility to evaluate compliance with the air quality requirements and reviews the facility's monitoring data. For further information on air permitting, contact Adam Shaffer, Bay City District Office, AQD.
EGLE, Water Resources Division (WRD) issues the permit for the discharge of treated wastewater into the Tittabawassee River. The WRD inspects the facility, reviews monitoring data, and conducts sampling of the facility's discharge. For further information on wastewater discharge permits, contact Matt Siler, Bay City District Office, WRD.
The Michigan Department of Agriculture and Rural Development (MDARD) is involved for agriculturally zoned properties in the floodplain areas and is available to answer questions regarding cleanup activities and the raising of chicken and livestock within areas of dioxin and furan contamination. For further information, contact Dr. Laura Johnson, Chief Science Officer, MDARD.
The Michigan Department of Health and Human Services (DHHS) is available to answer questions regarding any health concerns regarding dioxins and furans. For further information, contact Dr. Joost Van‘t Erve, DHHS.
Federal requirements
The United States Environmental Protection Agency (U.S. EPA), may conduct inspections to verify compliance with federal air, water, and hazardous waste regulations. Dow, EGLE, and the U.S. EPA have entered into an Administrative Settlement Agreement and Order of Consent for the cleanup of dioxins and furans released from legacy operations at Dow to the Tittabawassee and Saginaw Rivers and Floodplains and Saginaw Bay. The U.S. EPA is the lead agency for this Superfund site cleanup. Additional information on the cleanup is available on the U.S. EPA website.
The U.S. Fish and Wildlife Service (U.S. FWS) is also coordinating restoration activities for the Tittabawassee River under a settlement with Dow for a Natural Resources Damage Assessment (NRDA). Additional information regarding the restoration activities under the NRDA settlement is available on the U.S. FWS website.
