A tool Pennsylvania had left on the shelf for three decades just came back to life, and it happened right here in the Youghiogheny watershed. After a legal win by the Mountain Watershed Association, the state has agreed to formally study whether 11,000 acres of the Laurel Highlands are simply the wrong place to mine.
On July 7, 2026, Pennsylvania’s Environmental Hearing Board unanimously ruled that the Department of Environmental Protection was wrong to throw out the Mountain Watershed Association’s “unsuitable for mining” petition as frivolous. On August 6, DEP accepted it for review, the first time the state has advanced a petition like this since 1996.
What actually happened
The Mountain Watershed Association, a fellow watershed group working in our region, filed what is called an “unsuitable for mining” petition, a provision of Pennsylvania law that lets citizens ask the state to declare a specific area off-limits to mining because of the damage it would do. DEP initially rejected the petition as “frivolous.” MWA appealed, and the Environmental Hearing Board sided with them unanimously, finding that DEP had failed to follow its own regulations and ordering the agency to take the petition seriously. Weeks later, on August 6, DEP formally accepted it for technical review.
That is what makes this more than a single case. Pennsylvania’s unsuitable-for-mining program has been effectively dormant for a generation. Petitions piled up and went nowhere, with at least one from the early 1990s still awaiting a final decision more than three decades later. This ruling forces the program back into motion and puts a working example on the books for every watershed group in the state to point to.
The mine at the center of it
The petition targets LCT Energy’s proposed Rustic Ridge #2, an underground coal mine of roughly 2,300 acres near Donegal, in Westmoreland County. By reported permit figures, the operation would discharge as much as 2.8 million gallons of treated mine drainage a day into tributaries of Jacobs Creek, a stocked trout stream and coldwater fishery. Advocates have warned that even treated discharge can carry iron, manganese, and aluminum, that the wastewater would run warmer than the coldwater streams receiving it, and that building the mine would bury well over a thousand feet of Jacobs Creek headwaters. The 11,000-acre petition area spans Donegal and Mt. Pleasant townships, all of it in the Youghiogheny River watershed.
“We hope this jump-starts Pennsylvania’s long-stalled unsuitable-for-mining program.”

Acceptance is not the finish line. DEP now begins a technical study expected to run 10 months or more, examining water quality, wildlife, the legacy of historic mining in the area, and the cumulative economic effects, a review broader than a standard mine permit gets. At the end, the state will decide whether to designate all or part of the 11,000 acres as unsuitable for mining.
Why it matters for the rest of us
For every group in the H2O network, this is worth watching closely. It proves the unsuitable-for-mining petition is a real, usable tool again, not a dead letter, and it was proven in our own watershed, on the Youghiogheny. When a community can make the case that a place is too valuable, too fragile, or too scarred by past mining to take on more, Pennsylvania law now has a live path to hear it. That is a win worth learning from.
