Learn the Lingo

Do environmental terms sometimes sound like a foreign language to you? If so, you’re not alone. Many businesses and communities have difficulty keeping up with the latest environmental lingo. This feature will cover some common environmental terms you may encounter.  This time, we’ll focus on some frequently used air pollution control terminology.

Permit-to-Install and Operate (PTIO) — The type of air permit most small businesses need is the PTIO. The PTIO is required before installing and operating an air contaminant source. The PTIO lasts 5 to 10 years and is renewable.

General Permit — A general permit is an optional, “template” PTIO available to certain common air contaminant sources. Because they are developed in advance, general permits eliminate much of the review steps and speed up the permitting process.

Permit-by- Rule (PBR) — A PBR is a specific permit provision in the Ohio Administrative Code that applies to certain types of low-emitting air pollution sources. Companies may use the PBR as an option in place of the PTIO. The PBR is free, does not expire, and requires a simple, one-page notification to Ohio EPA.

De Minimis Air Pollution Source — De minimis sources emit less than ten pounds per day of any air contaminant and less than one ton per year (2,000 pounds) of any hazardous air pollutant or combination of hazardous air pollutants.  If you claim a de minimis exemption based on actual emissions, you must keep records onsite to document actual daily emissions from the source. You do not need to notify Ohio EPA if you claim a de minimis exemption.
