Region 3 Library Services
The Region 3 Library's mission is to provide accurate, timely environmental information to EPA staff and the public.
The public is welcome to visit the library. We are located at:
1650 Arch Street (entrance to EPA offices is on Arch St.)
Philadelphia, PA 19103
Driving directions are available. However, since public parking is limited and expensive, public transportation is recommended. The EPA Region 3 Office is convenient to several methods of public transportation, including the SEPTA Regional Rails, PATCO, the Frankford El and a number of bus routes.
All visitors to the Region 3 office must show a picture ID such as a current driver's license.
