EPA Region 10 developed an Online Map to view the census-identified “Urbanized Areas” for current permittees and new communities identified for permit coverage.
These maps are provided for informational purposes only. If you are uncertain whether a specific area is covered by a particular permit, please contact the permitted community or DEQ.
