Massachusetts Department of Environmental Regulation (MassDEP)

Membership in ABC TMA may help your organization meet several regulatory requirements under the MassDEP Rideshare Regulation ( 310 CMR 7.16).  The Rideshare Regulation  is an air quality initiative that requires businesses and academic institutions to develop plans and set goals to reduce commuter drive alone trips by 25%. By reducing drive-alone trips, your organization will help Massachusetts reduce air pollution, traffic congestion, and spending on road construction and repair projects. 


The following businesses are currently required to file base and update reports with MassDEP: 

  • Businesses with 1,000 or more applicable commuters.
  • Educational institutions with 1,000 or more applicable commuters.
  • Businesses with 250 or more applicable commuters that are also subject to the Massachusetts Air Operating Permit Program (310 CMR 7.00, Appendix C).
