2018 NOI/APPLICATION PREPARATION

  • 2018 Permit NOI/Application Due Date Report (PDF)
    This report provides, for each MS4, whether the 2018 MS4 permit is expected to be a General Permit or an Individual Permit, the amount of the fee, the due date and whether a PRP or TMDL Plan is expected to be attached. Please advise DEP at RA-EPPAMS4@pa.gov if you believe there are errors in the report.

  • eMapPA
    This DEP application can be used to view urbanized areas (UAs) based on the 2000 and 2010 censuses along with other facilities and features. Note that use of the web-based GIS application may be more appropriate for Pollutant Reduction Plans because it does not include 2016 tentative stream impairments, which are not required to be addressed in the 2018-2023 permit term.
