PNDI Environmental Review Tool

The Pennsylvania Natural Diversity Inventory Environmental Review Tool (PNDI ER Tool) enables the public to perform online PNDI searches for potential impacts to threatened, endangered, special concern species and special concern resources in PA. You will need to create an account to access the PNDI tool.

**Important Notice**

As of May 4, 2015, the northern long-eared bat (NLEB) federal listing determination of threatened and the interim 4(d) rule is effective. The PNDI Tool has been updated to reflect this change.

To ensure your project considers potential impacts to this federally-listed species, projects reviewed prior to May 4, 2015 should be re-screened using the PNDI Tool. However, the entire PNDI process with DCNR, PGC and FBC does not need repeated; only the new screening for USFWS. Please see the guidance below for clarification:

  • If the new PNDI Receipt states No Further Review Required with the USFWS, Pennsylvania Department of Conservation and Natural Resources (DCNR), Pennsylvania Fish and Boat Commission (PFBC) and Pennsylvania Game Commission (PGC), no further coordination is necessary.
  • If the new PNDI Receipt states Further Review Required with USFWS, the applicant will need to coordinate with the USFWS.
  • If the new PNDI Receipt states Further Review Required with DCNR, PFBC and/or PGC, compare the old PNDI Receipt against the new PNDI Receipt. If the same species or the same number of sensitive species are listed, then no further coordination is necessary.
    • If it is unclear whether the same species are listed on the PNDI Receipt, the applicant should contact the resource agency listed for verification and review of the species.

The applicant should submit the original PNDI Receipt, any documentation from the resource agency related to any potential impacts, and the new updated PNDI Receipt obtained after May 4, 2015 to the permitting agency. Please visit the PA DEP website and US Army Corps website for further information on permitting and the NLEB.
