Massachusetts Air Permitting: How CPI Supports Your Compliance Process

CPI designs and builds oxidizer systems — we are not a permitting firm, and every Massachusetts facility's permit obligations depend on details specific to that site. Engaging an air permitting professional who is familiar not just with federal requirements, but with Massachusetts's air permitting rules, is strongly recommended.

Here's how CPI fits into that process:

  1. Technical data your permit application will need. Emission rates, destruction/removal efficiency, stack parameters, fuel usage, and control technology specifications, delivered as part of every proposal.
  2. A design matched to your compliance target. Our applications engineering team coordinates with the parties responsible for your permitting so the oxidizer is sized to meet your permit's destruction efficiency and reporting requirements from day one.
  3. Ongoing support once you're operating. Equipment performance data for emissions reporting or agency inspections, whenever your compliance team needs it.
  4. A track record Massachusetts regulators already recognize. CPI oxidizer systems are permitted and operating across Massachusetts, helping our customers stay in compliance with their permit obligations.

Frequently Asked Questions

Can CPI manufacture a regenerative thermal oxidizer for a Massachusetts facility?

Yes. CPI designs and manufactures custom RTOs, catalytic oxidizers, and thermal oxidizers for Massachusetts manufacturers, built on successful implementations throughout Massachusetts and nationwide.

Are there CPI oxidizers already running in Massachusetts today?

Yes — CPI oxidizer systems are installed and operating at Massachusetts facilities, permitted and accepted by MassDEP. That in-state history means Massachusetts regulators are already familiar with how CPI designs and documents its systems.

Does my facility need a Limited Plan Approval or a full Plan Approval?

It depends on the scale and emissions of the project. Your permitting consultant, EHS team, or engineering group can confirm which approval path applies to your site.

Will CPI service equipment it didn't originally manufacture?

Yes. CPI services most makes and models of regenerative thermal oxidizers, catalytic oxidizers, and thermal oxidizers, not only the systems we built ourselves.

Does CPI manage MassDEP permitting on our behalf?

No. CPI is not a permitting firm. We recommend confirming your specific requirements with an environmental consultant, EHS resource, or engineering team - CPI's role is supplying the oxidizer information that process depends on.

Is CPI a resource for environmental consultants working on Massachusetts projects?

Yes. CPI works closely with environmental consultants on BACT/MACT analysis and project support, backed by a proven track record of oxidizers already operating in Massachusetts.
