Air Quality

Building a new facility or making major modifications to an existing one? Barr has provided fast-track air quality permitting assistance for new facilities in both attainment and non-attainment areas. And because we know that your compliance responsibilities don't end when you submit the permit application, we also provide the support services your facility needs, such as:

• Routine record keeping and reporting
• Permit modification assistance
• Stack testing

If your facility has indoor air quality issues, we can help resolve those, too.

The air quality services we offer include:

• Air Quality Permitting
• Testing, Monitoring, and Modeling
• Indoor Air Quality Assessment
• Mercury-related services (also see the Hot Topic archive in the Client Resources section of this website)
