Regenerative Thermal Oxidizers and VOC Control Systems in Kentucky

Kentucky Air Permitting: How CPI Supports Your Compliance Process

CPI designs and builds oxidizer systems — we are not a permitting firm, and every Kentucky 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 Kentucky's air permitting rules, is strongly recommended.

Here's how CPI fits into that process:

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.
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.
Ongoing support once you're operating. Equipment performance data for emissions reporting or agency inspections, whenever your compliance team needs it.
A track record Kentucky regulators already recognize. CPI oxidizer systems are permitted and operating across Kentucky, helping our customers stay in compliance with their permit obligations.

Kentucky Air Permitting Rules for Oxidizers

Permitting authority: Kentucky Division for Air Quality (DAQ), part of the Energy and Environment Cabinet — responsible for every county except Jefferson
EPA region: U.S. EPA Region 4 (Southeast)
Local delegation exception: Jefferson County (Louisville) is regulated by the Louisville Metro Air Pollution Control District (APCD) instead of the state DAQ
Major source permits: Title V, required for the largest sources statewide
Synthetic minor permits: available statewide; in Jefferson County these are specifically called Federally Enforceable District-Origin Operating Permits (FEDOOPs), issued to sources that accept emissions limits below major-source levels
Minor sources in Louisville: APCD issues a single combined construct-and-operate permit with no expiration date — a simpler process than the separate construction/operating tracks used in many other states

Supporting Your Project Team

Whether your Kentucky project runs through an outside environmental consultant, an in-house EHS group, or your engineering team, CPI works alongside them, offering:

BACT/MACT analysis support, with the technical data needed to weigh control technology options.
A real installation history in Kentucky that regulators have already reviewed and accepted.
Turn-key project support spanning evaluation through commissioning, including installation estimates.
A 24-hour Technical Service Group standing by well after startup.

Aftermarket Service & Support — Kentucky

CPI's aftermarket service is performed by direct CPI employees — not third-party contractors — so Kentucky facilities get factory-trained technicians who know CPI equipment inside and out.

Service performed by CPI's own technicians
Preventive maintenance
Emergency service, including 24/7 phone support
Annual inspections and testing support, helping facilities meet inspection or maintenance requirements that may be specified in their air permit

Frequently Asked Questions

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

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

Are there CPI oxidizers already running in Kentucky today?

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

Does my facility apply through the state DAQ, or through Louisville Metro APCD?

It depends on location. Facilities in Jefferson County (Louisville) apply through the Louisville Metro Air Pollution Control District; every other Kentucky county applies through the state Division for Air Quality. Your permitting consultant, EHS team, or engineering group can confirm which authority 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 DAQ (or APCD) 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 Kentucky 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 Kentucky.
