What you can do
Open a project on the map. If a comment period is open, the record shows the deadline under Permit. The Pennsylvania Bulletin notice linked as the primary document names the DEP regional office (Southeast, Northeast, Southcentral, Northcentral, Southwest, or Northwest) and the contact to send written comments to; comments must arrive within the 30-day window. You can ask DEP for a public hearing in the same comment. This site is independent and is not affiliated with DEP or any company named on it.
Want to know when this changes? The Filings Wire is every new or changed permit action in PA, VA and TX, with the agency document and the figures it states — a free Monday summary, or the full issue and CSV for subscribers.
"Permitted" means at least one permit of any type is issued; "under review" means an application is filed or noticed and no permit is issued yet; "announced" means the record anticipates permits but none is filed. None of this says anything is being built. Counts reflect the ledger sheet as of Sep 28, 2026; absence here means we have not identified a project from public records, not that none exists.
