The Arkansas Department of Energy and Environment - Division of Environmental Quality (“ADEQ”) and APAC-Central, Inc. (“APAC”) entered into a May 26th Consent Administrative Order (“CAO”) addressing an alleged violation of an Air Permit. See Case #: CAO-26-0005.
APAC is stated to operate a crushed and broken stone mining and quarrying facility located in Gravette, Arkansas.
The facility is stated to have submitted a Notice of Intent for inclusion in Air Minor Source Permit 1916- AGP-000 on November 15, 2024.
ADEQ subsequently issued coverage under the general permit on January 3, 2025.
The facility is stated to be subject to the provisions of C.F.R. Part 60, Subpart OOO - Standards of Performance for Nonmetallic Mineral Processing Plants.
APAC is stated to have submitted an emission test report for testing performed on May 14, 2025, and July 2-3, 2025, for Visible Emissions (“VE”). ADEQ informed APAC in a November 19, 2025 letter that the stack test report indicated that the 48x25 Fines Cone Conveyor 1 and the Plant Leg Diverter Chute Bin were out of compliance with the Permit at the time of testing.
APAC submitted additional emissions test results on November 17, 2025.
ADEQ subsequently informed APAC that the previously referenced sources were in compliance.
The CAO alleges the following violation:
- Failure to comply with a delegated NSPS requirement.
A civil penalty of $6,400 is assessed, which could have been reduced to $3,200 if the CAO was signed and returned to ADEQ within 20 calendar days of its receipt.
