Stormwater Management

Stormwater Program

In 2003, Westmoreland County Public Works became one of the several Counties within the Commonwealth of Pennsylvania required to have its municipal separate storm sewer system (MS4) regulated under the Pennsylvania Department of Environmental Protection’s (PADEP’s) National Pollution Discharge Elimination System (NPDES) Phase II permit program for storm water discharges from storm sewer systems within small- to medium-sized communities within urbanized areas as defined by the 2010 U.S. Census.

Homeowner’s Guide to Stormwater

This guide (PDF) has been funded by the League of Women Voters of Pennsylvania Citizen Education Fund through a Section 319 federal Clean Water Act grant from the Pennsylvania Department of Environmental Protection, administered by the U.S. Environmental Protection Agency.

The Southwestern Pennsylvania’s Homeowner’s Guide to Stormwater is based upon The Homeowner’s Guide to Stormwater produced by the Little Conestoga Partnership and its funder the National Fish and Wildlife Foundation.
