Hazardous Waste Management
(Environment, Great Lakes, and Energy , Waste Management & Radiological Protection Division)

The purpose of the rules is to maintain federal authorization to administer the state's Hazardous Waste Management Program under Part 111, Hazardous Waste Management, of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended (Act 451), in lieu of the federal Hazardous Waste Management Program under the Resource Conservation and Recovery Act of 1976, as amended by the Hazardous and Solid Waste Amendments of 1984 (RCRA); to improve the overall quality of the rules in terms of clarification of existing requirements and areas of program coverage; and to reduce some of the burdens on the regulated community by providing streamlined and flexible requirements. The rules address federal revisions required to maintain authorization and those that authorized states have the option of incorporating into their rules for consistency purposes. The revisions address generator improvement, import/export, and electronic manifesting requirements. The rules also address revisions based on DEQ and public recommendations relating to hazardous waste identification and listing, aerosol cans as universal waste, adoption by reference updates, and typographical corrections.

2019-001 EG

Oil and Gas Operations
(Environment, Great Lakes, and Energy , Oil, Gas, & Minerals Division)

The DEQ is in the process of applying for primacy from the United States Environmental Protection Agency (U.S. EPA) to implement the Class II Underground Injection Control Program. This requires the DEQ to demonstrate that the State of Michigan has an equally effective program for the protection of underground sources of drinking water (USDWs) compared to federal standards in accordance with Section 1425 of the Safe Drinking Water Act. Definitions, in particular, are important for demonstrating the State of Michigan program is protecting the same USDWs and that USDWs are unequivocally protected from endangerment. The DEQ regulates Class II injection wells under Part 615, Supervisor of Wells, of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended, and the Oil and Gas Operations rules that are promulgated under Part 615. A USDW is described in current state rules as fresh water or mineral water that is either used for drinking water or that can potentially be used for drinking water and has fewer than 10,000 milligrams per liter total dissolved solids.

2019-035 EG

Supplying Water to the Public
(Environment, Great Lakes, and Energy , Drinking Water & Municipal Assistance Division)

To establish enforceable drinking water standards for per- and polyfluoroalkyl substances (PFAS) found during the 2018 sampling of Michigan’s public drinking water supplies. While the U.S. Environmental Protection Agency has established an unenforceable lifetime health advisory level for total perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), many academia, health officials, and the Agency for Toxic Substances and Disease Registry (ASTDR) deem this advisory level is too high. In addition, the lack of an enforceable standard for PFOS and PFOA and other commonly found PFAS chemicals impairs the DEQ’s ability to take enforceable actions to protect human health and the environment.
