2.7 PWD and Pennsylvania Department of Environmental Protection

This Section outlines the circumstances in which the Philadelphia Water Department (PWD) and the Pennsylvania Department of Environmental Protection (PA DEP) jointly review projects, as well as other circumstances in which reviews are conducted entirely by PA DEP. PWD does not determine what State permits apply to a development project. This is the responsibility of the applicant, who should contact PA DEP directly with any questions.

Please note that projects that are exempt from PA DEP Permit Requirements (such as projects receiving ACOE 404 Permits for Wetlands Mitigation) are not necessarily exempt from the PWD Stormwater Regulations. The applicant may consult Section 1.1 for more information on Applicability Factors and contact PWD with any questions.

2.7.1 National Pollutant Discharge Elimination System Permits

Most projects proposing more than one acre of earth disturbance are subject to both the General (PAG-02) National Pollutant Discharge Elimination System (NPDES) Permit or Individual NPDES Permit for Stormwater Discharges Associated with Construction Activities and the PWD Stormwater Regulations (Stormwater Regulations). NPDES Permits for land development in Philadelphia are issued by PA DEP, not PWD. The applicants must send NPDES Permit Applications to the PA DEP Southeast Regional Office in Norristown, PA.  The applicant should contact PA DEP directly with questions concerning NPDES Permits. Municipal Notifications (such as those required under PA Acts 67, 68, and 127 of 2000) should be sent to PWD’s Projects Control Unit. For mailing address, the applicant is referred to Section 2.0.3. The PWD project tracking number should be listed on all notifications.

PWD recommends that NPDES Permit Applications are submitted concurrently to PA DEP with the Post-Construction Stormwater Management Plan (PCSMP) Review Phase Submission Package (see Section 2.3) to PWD. Instructions for completing the NPDES Permit Applications should be obtained directly from PA DEP.  However, the applicant may use the following general guidance when preparing and submitting a NPDES Permit Application:

  • On the NPDES Permit Application Notice of Intent for Coverage, the applicant may check under “2. PCSM Plan” that the project is meeting “C. Alternative Design Standard” and list the PWD Stormwater Regulations as the requirement being met.
  • If the applicant is applying for a phased NPDES Permit, the phases listed under Section C.4 must match the order of phases submitted to PWD under individual project tracking numbers (see Section 2.1.1 for information on PWD Stormwater Plan Review’s project tracking numbers).
  • The applicant must provide matching plans and reports to both PWD and PA DEP.
  • If the applicant is submitting an Infiltration Waiver Request Form to PWD for on-site contamination (Section 3.3), the applicant must also submit this waiver request to PA DEP for review as part of the NPDES Permit Application.

In addition to comments received by PWD, comments the applicant receives from PA DEP must also be incorporated into the PCSMP and Erosion and Sediment Control (E&S) Plans for PWD Stormwater Plan Review to issue PCSMP approval. PCSMP approval is a prerequisite for receiving a NPDES Permit. However, PWD Stormwater Plan Review will not issue PCSMP approval until receiving confirmation from PA DEP that there are no outstanding comments with the NPDES Permit review.

The applicant must present a copy of the NPDES Permit to PWD Water Transport Records in order to receive PWD sign-off on a Building Permit.

2.7.2 Other PA DEP Requirements

There are circumstances in addition to NPDES Permits for construction activities in which PA DEP review may be required for a project proposed in Philadelphia. These may include projects that are exempt from NPDES Permit Requirements but are still required to have an E&S Plan approved by PA DEP per 025 Pa. Code §102. This also includes projects that propose a new discharge to a water body or which propose activities within regulated waters of the Commonwealth as defined in 025 Pa. Code §105. The applicant is responsible for determining which State requirements apply to their project and are encouraged to contact PA DEP directly with any questions.
