The Arkansas Department of Energy & Environment – Division of Environmental Quality (“DEQ”) and PotlatchDeltic Manufacturing, LLC (“PotlatchDeltic”) entered into a March 19th Consent Administrative Order (“CAO”) addressing alleged violations of an air permit. See LIS No. 24-057.
The CAO provides that PotlatchDeltic owns and operates a lumber and chip mill in Waldo, Arkansas.
The Facility operates pursuant to an air permit.
The Facility is stated to have conducted stack testing at wood fired boilers #1, #2, and #3 to demonstrate compliance with applicable emission limits on April 11-13, 2023.
Follow-up stack testing at SN-13 was conducted on May 19, 2023, to demonstrate compliance with the PM emission limit following completion of corrective actions to address excess PM emissions discovered in preliminary results collected during the April 13, 2023, test.
DEQ personnel are stated to have performed an evaluation of stack test reports on June 26, 2023, for the referenced testing.
The CAO states that in those evaluations it was determined that the PM test results for SN-13 and SN-14 were invalid because the required volume of air specified for the applicable boiler category had not been collected at the time of testing. All other results were determined to be valid.
PotlatchDeltic conducted follow-up stack testing. DEQ’s evaluation of the follow-up stack testing determined compliance with the applicable limits.
The CAO states that an evaluation of the stack test report submitted on September 26, 2023, indicated the Facility exceeded the filterable PM emission limit at SN-14, violating Specific Condition 34 of the permit.
A retest of SN-14 was conducted and DEQ subsequently determined that the Facility was in compliance with the air permit.
PotlatchDeltic neither admits nor denies the factual and legal allegations contained in the CAO.
A civil penalty of $4,920 is assessed.
