ADEQ Air Permits in 2026: 6 VOC Checks Arizona Plants Should Revisit Now

Frequently Asked Questions

What is the first thing an Arizona plant should review for VOC permit compliance in 2026?

Start by comparing current operations to the assumptions behind the permit. Check whether material use, VOC content, equipment, and production levels still match the basis used for permitting and reporting.

Which materials are commonly missed in VOC calculations?

Facilities often miss ancillary materials such as gun cleaner, purge solvent, line flushes, maintenance coatings, and other cleanup products. These smaller-use items can still affect totals and threshold status.

How often should VOC totals be reviewed?

Review them monthly and track any rolling totals required by the permit. Waiting until year-end makes it much easier to miss a developing threshold problem.

What records should be ready if ADEQ asks for support?

Have monthly usage logs, current product data, calculation worksheets, equipment lists, and any control-device records organized and easy to produce. The goal is to show a repeatable method tied to actual site activity.

Why do VOC compliance issues happen even when a plant has a permit?

Because operations change faster than the compliance math. New products, added shifts, different cleaning practices, or overlooked emission points can make actual emissions drift away from permit assumptions.
