All RADIUS 4.0 users must upgrade to RADIUS 5.0 for electronic preparation and submittal of air permit applications and emission statements to the Department. RADIUS 4.0 submissions will not be accepted by the Department.  Please visit our What’s New in RADIUS page to learn more about this new release.

RADIUS is software provided by NJDEP for electronic preparation and submittal of air permit applications and emission statements to the Department.  RADIUS can also be used to import permit files in RADIUS format received from NJDEP.  The system is designed to interact with the Department’s environmental regulation database, the New Jersey Environmental Management System (NJEMS). 

With the newest update to RADIUS (RADIUS 5.0), users have the option of submitting files online via DEP Online (http://www.njdeponline.com) as of January 15, 2013, or submitting by mail with a paper certification.  For information about what changes have been made to RADIUS and how to submit these files, please read the “User Guide for Online RADIUS Submittals” available at the Air Quality Permitting Program’s Applications & Forms page: http://nj.gov/dep/aqpp/applying.html
