Phase II Storm Water Management Program

As of March 10, 2003, the City of Erie has a storm water permit from Pennsylvania DEP that regulates the storm water discharges from our Municipal Separate Storm Sewer System (MS4).

This permit is the result of new storm water regulations developed by the U.S. Environmental Protection Agency under the Clean Water Act. You may hear this federal regulation referred to as the Phase II Storm Water Program.

This federal regulation required PA DEP to develop a program that meets the federal requirements. As a result, the Department developed a permit program with the goal of reducing the pollutants associated with storm water runoff.

Our community is one of nearly 900 required to obtain a permit. Under the Phase II regulation, all owners of Municipal Separate Storm Sewer Systems (MS4s) in Urbanized Areas, as well as in other areas, to obtain a Phase II MS4 Storm Water permit. Two larger cities, Allentown and Philadelphia, have Phase I Storm Water permits.

The overall goal of the Phase II MS4 Storm Water Program is to reduce pollutants found in storm water runoff from urbanized or urbanizing areas to the "maximum extent practicable".

To achieve this goal, our permit requires us to conduct three major activities:

  • Develop and implement a storm water management program, consisting of six (6) minimum control measures (listed below).
  • Track our progress in implementing our storm water management program against a set of measurable goals.
  • Report on our progress to PA DEP and the community every year through an annual report.

Our Storm Water Program consists of these six (6) minimum control measures:

  • Public Education and Outreach.
  • Public Involvement and Participation.
  • Illicit Discharge Detection and Elimination.
  • Construction Site Storm Water Runoff Control.
  • Post-Construction Storm Water Management.
  • Pollution Prevention and Good Housekeeping for Municipal Operations and Maintenance.

Successful implementation of the six (6) minimum control measures will benefit our community now and in the future. Some expected benefits of our Storm Water Program are:

  • Enhanced fishing
  • Enhanced opportunities for recreation
  • Reduced flood damage
  • Drinking water benefits
  • Navigational benefits
  • Reduced illness
  • Enhanced aesthetic value
