This follows a long-established pattern across federal agencies, where environmentalists use regulations and enforcement to accomplish their wish list when it couldn't be done under normal free market or constitutional means.
In DC, the (thoroughly unconstitutional) National Park Service refused to offer a lease or even a concessionaire contract for the former Tommy Long's Anacostia Marina. It was the only place with a travel lift at the dead end of the Potomac. If you had a 15' or bigger beam, with Anacostia Marina closed for good, it's at least a 100 mile cruise to the first marina that could haul you. Owners of smaller boats can drive 15 miles south to Fort Washington Marina to be hauled.
Anyway, now Tommy Long's place is...get ready for it...a paddle board and kayak rental and launch site. The thinking is clearly "let's make icky powerboats so inconvenient they just don't come here."
Don't think they won't impose their iron-fist rules on you just because their ideas make zero practical sense. Environmentalism is a religion, and our federal government is riddled with its high priests.
