The record, newest first

  1. Ten Mingo County residents sued TransGas and three federal agencies (the Army Corps, Fish and Wildlife Service and FERC) in federal court in Charleston, asking that work on the Adams Fork project stop until federal wildlife, water, environmental-review and pipeline approvals are complete; no ruling was found. (West Virginia Watch, Dec. 5, 2025; WOWK 13 News, Dec. 11, 2025)

  2. The DEP issued permit R13-3714 for the Harless plant. (West Virginia Highlands Conservancy, Oct. 11, 2025)

  3. The DEP advertised the draft permit and took comment; a virtual meeting followed Aug. 18 and an in-person hearing in Gilbert on Sept. 18. (WV Department of Environmental Protection, Division of Air Quality, July 9, 2025; WV Department of Environmental Protection, Division of Air Quality, Sept. 18, 2025)

  4. TransGas submitted the Harless air permit application at the same time as the Twisted Gun application. (WV Department of Environmental Protection, Division of Air Quality, Sept. 18, 2025; WV Department of Environmental Protection, Division of Air Quality, July 9, 2025)

Conflicts and open questions

  • DEP places this site on Mine Road beside Mohawk Industries at the Harless Industrial Park; it is separate from the TransGas ammonia plant site.
  • The final R13-3714 permit document could not be opened; the Oct. 2, 2025 issue date is from WVHC's account of both permits.
  • Holden is a Logan County community; the DEP lists the facility in Mingo County.
  • Residents' federal lawsuit (filed Dec. 3, 2025) covers the whole Adams Fork project; plaintiffs are private individuals; do not name them.
