Three Pollution Control Projects Funded in Chester County

Chapter 102 Permitting Update



An updated version of the PCSM Spreadsheet has been posted to DEP’s website (version 1.7).  This version includes two updates to the way water quality calculations are handled: 1) a more detailed method is provided, as an option, for untreated stormwater, by allowing the user to characterize the land cover within undetained areas, and 2) pollutant loads are no longer calculated for outflows from MRC BMPs, as those flows are considered “managed.” 

Use of version 1.7 is not required.  Version 1.6 (or later) is required, although if an applicant is having difficulty meeting water quality requirements on a site, it’s recommended to use version 1.7.

There have also been updates to the MRC documents (MRC paper, FAQ, Design Examples, and Design Summary Sheet).  The updates are intended to clarify some issues that have come to our attention concerning complex sites, as well as update old references to worksheets that were previously used.  None of the actual design standards have changed.

Effective December 8, 2019

New forms are required to be submitted for applications for coverage under PAG-02 and Individual NPDES Permit Applications. Please visit PA DEP’s E&S Resources website, located here, for links to the new documents (including applications, forms, instructions, and modules). It is recommended to schedule a pre-application meeting for all proposed projects needing NPDES permits. Please contact Gordon Roscovich, Urban Team Leader, if you have any questions.

On December 6, 2019, CCCD notified permittees, operators, and plan designers of projects with active coverage under PAG-02 General Permit authorizing stormwater discharges associated with construction activities of effective changes to their permit. DEP is asking that permittees submit an acknowledgement form directly to them for each PAG-02 permitted project site.
