Covers 22 of this county's 45 municipalities — the rest run their own program
Your township or borough
23 municipalities run their own Act 537 program here
Under Act 537 a municipality may administer on-lot permits itself, through its own certified Sewage Enforcement Officer. These do — so the application, the fee and the inspection come from your own township or borough office rather than a county department:
Apollo Borough · Applewold Borough · Atwood Borough · Bethel Township · Boggs Township · Cadogan Township · Dayton Borough · Elderton Borough · Ford City Borough · Ford Cliff Borough · Freeport Borough · Kittanning Borough · Kittanning Township · Leechburg Borough · Manorville Borough · North Apollo Borough · Parker · Perry Township · Plumcreek Township · South Bend Township · South Bethlehem Borough · West Kittanning Borough · Worthington Borough
Source: PA DEP’s municipal on-lot sewage service-area tabulation, which publishes the agency for each municipality and no contact details — so we print no phone number we cannot source.
Permit fees, forms & process
New installs and major repairs need a permit from the municipality or joint local agency under Act 537, and the rules that bind are the local ones.
This county’s full guide is still in production — the authority contact shown here is the official source in the meantime.
Four things decide what you can build and what it costs: zoning, environmental protections, power for aerobic systems, and the ground itself. We publish each one only where we have checked it — and say so plainly where the answer is “same as the rest of Pennsylvania”.
Zoning & land use
Armstrong County has a county subdivision ordinance, adopted in 2016, which governs in any municipality that has not adopted its own and is repealed pro tanto the moment one does. Section 514.A leaves ordinary lot area and width to the municipal zoning ordinance where there is one. On sewage, DEP's service tabulation puts 22 of the county's 45 municipalities under the Armstrong County Sewage Enforcement Agency and leaves the other 23 running their own program.
Armstrong County has no Exceptional Value waters, but 1 entries on DEP's Chapter 93 drainage lists are High Quality — including Pine Creek. A lot draining to one loses the § 71.51(b) planning exemption, so the sewage module goes to the municipality and then to DEP. That is a second reviewer, not a different septic system. Check your own stream before assuming the ordinary path.
The dominant constraint here is slow-percolating subsoil below 12 inches (81.8% of rated soils), followed by bedrock within 60 inches of the surface (61.5%). NRCS rates 93.9% of rated ground very limited for a conventional in-ground trench, 81.5% for a sand mound and 54.1% for drip irrigation -- where conventional is out, drip is often the system that works.
