The City of Aliquippa is currently permitted to discharge stormwater under existing NPDES Permit No. PAG-136334, with authorization being granted through a Federal regulated Small Municipal Separate Storm Sewer System (MS4) program. The goal of the MS4 program is to reduce the discharge of pollutants to stormwater in order to protect water quality. The City will continue to implement requirements of the MS4 program to protect water resources in the community through the following:
Create a better understanding of the links between land use, runoff management, water quality, and flood control.
Promote awareness of the storm sewer system as an essential component of the municipal infrastructure, and how household or business pollutants must be eliminated from the system.
Encourage public participation in community activities such as waterway cleanup or restoration.
Work with the private-developer, commercial, industrial and homeowner communities to reduce sediment and nutrient runoff to waterways.
Make a stronger, fact-based connection between pollution reduction and decreased costs of treating the public drinking water supply.
Participate in and support local watershed groups’ organizational meetings and awareness events.
Satisfy the requirements of the City of Aliquippa’s MS4 General Permit.

Residents and business owners in the City of Aliquippa can help by the following:
