Any Source

Roll up or drill down emissions data and changes to chemical throughput from any type of source, including data from CMS


Every Pollutant

Our platform takes care of HAPs, VOCs, VHAPs, GHGs, NOx, SOx, particulate matter, and other criteria pollutants

Icon_data safety

Exhaustive QA/QC

Emission calculations and material data adhere to the most rigorous standards and are saved in a secure, cloud-hosted vault for peace of mind

Built-in and By-design Reporting

Automatically generate air emission reports on a pre-set schedule or on demand (such as in response to accidental releases). Reports come in a digital format that can be uploaded to state reporting e-tools where applicable.

We have industry-specific reports for:

  • Aerospace Manufacturing & Rework (GG)
  • Automobile Surface Coating (IIII)
  • Wood Furniture Surface Coating (JJ)
  • Miscellaneous Metal Parts (MMMM)
  • Plastic Parts Surface Coating (PPPP)
  • Wood-building Surface Coating (QQQQ)
  • Boat Manufacturing (VVVV)
  • Fiber Reinforced Plastics (WWWW)
  • ...and more!

If we don't have your subpart already built into the system, we will design and implement a report for you!

Frequently Asked Questions

Understanding your obligations to the Clean Air Act can be complicated. We are here to help.

What are NESHAPs?

National Emission Standards for Hazardous Air Pollutants (NESHAPs) were created as an extension of the CAA to monitor the amount of hazardous air pollutants (HAPs) from stationary sources—factories, refineries, boilers, power plants, etc.

What are MACT standards?
The percentage of air emissions that can be prevented is often limited by the current level of available technology. That's why the EPA developed Maximum Achievable Control Technology (MACT) standards: the EPA sets the emission levels being achieved by the top-performing sources in that industry (for similar source types) as the industry baseline, known as the "MACT floor". Sources must, at a minimum, achieve a level of emissions control (for that industry equivalent to the MACT floor.
How does the EPA enforce NESHAP/MACT standards?
In short, the EPA sets emission standards on an industry-, chemical-, or manufacturing process-specific basis. Owners and operators at industrial facilities must conduct initial performance tests on all sources to demonstrate compliance and, throughout their operation, monitor their operating parameters. In addition, sources may be required to install and operate continuous emission monitors.
What should I expect from an EPA inspection?

EPA auditors regularly conduct inspections on regulated facilities to evaluate compliance and identify and address excess emissions. Inspectors may engage in one or several of the following:

  • Interviewing facility personnel
  • Examining reports and records
  • Reviewing leak detection and repair methods and practices
  • Inspecting the processes that have emissions points subject to the standard sampling wastewater discharges, if applicable

ERA software ROCKS - helps save time

ERA's programs are a HUGE life-saver for me. I'm able to get a lot of regulatory reports done in hours vs weeks. Specifically TRI, Tier II, and various emissions reports/inventories. I'm now working on adding additional modules for safety and other reports.
