Reg Nav’s newest tool for use by owners of auto body shops.


Clean Air Act (CAA) compliance can be a complicated task. Fortunately, E-Enterprise is helping to ease the job with online compliance assistance Regulation Navigation (Reg Nav) tools designed to help both regulators and the regulated community assess whether certain air quality rules apply to a facility.

Reg Nav walks users through successive questions about facilities, resulting in personalized documents outlining the associated regulatory requirements. This simplifies and encourages compliance with complex regulations, reduces compliance assistance requests to government agencies, and streamlines reporting.

While most of the interactive tools are based on existing air quality regulation flowcharts created by the Texas Commission on Environmental Quality, the newest tool stems from work conducted by the North Carolina Department of Environmental Quality. This software program is designed to help the owners and operators of mobile or stationary auto body shops determine if they are eligible for a specific exemption under the National Emissions Standards for Hazardous Air Pollutants (NESHAP).

As new tools are created and added, states provide feedback on which rules should be prioritized, and review and provide comments on the beta versions before the tools go live. Once available, the tools are widely used. The Reg Nav landing page receives 2,300 page views per year, with individual tools receiving 5,000-7,000 views per year.
Upcoming additions to the toolbox will include continued development of and updates to all existing Municipal Solid Waste Landfill-related tools that changed with the promulgation of Subpart AAAA in the NESHAP.
