Ammex, Inc. v. Michigan Department of Agriculture, No. 20-1250 (6th Cir. 2022)
Annotate this Case
Ammex operates a duty-free gas station in Wayne County, Michigan, near the bridge to Canada, but positioned “beyond the exit point” for domestic commerce established by U.S. Customs and Border Protection. In 2012, the Michigan Department of Agriculture and Rural Development (MDARD) sought to enforce an Environmental Protection Agency (EPA) rule requiring Wayne County gas stations to dispense low-pressure gasoline in the summer. MDARD, in conjunction with the EPA, implemented this rule to bring Southeast Michigan’s ozone levels into compliance with the Clean Air Act.
Because of its unique location and certain sales privileges granted to it by U.S. customs law, Ammex resisted efforts to apply the rule to its gasoline sales. In 2019, the Sixth Circuit determined that MDARD was enforcing federal regulatory law, and was not in violation of the Supremacy Clause or dormant Foreign Commerce Clause. Ammex then argued that the environmental rule, properly construed, did not apply to Ammex and that the customs statute giving Ammex the right to sell duty-free goods supersedes the environmental regulation and renders it unenforceable against Ammex. The Sixth Circuit affirmed the dismissal of those claims. the Summer Fuel Law unambiguously applies to Ammex and does not impact Ammex’s ability to sell gas duty-free.
