County air quality officials are giving North Side residents two more weeks to comment on regulations proposed for Acme Materials and Construction’s asphalt plant on East Hawthorne.
Plant operators have agreed with county and federal officials that they will not produce more than 300,000 tons of asphalt per year.
Last year, the plant produced 133,000 tons of concrete.
Residents and concerned citizens have until Aug. 2 to file comments with the Spokane County Air Pollution Control Authority.
After that date, unless it hears major concerns, SCAPCA will register Acme’s North Side plant and monitor it on a yearly basis.
Acme’s Hawthorne plant produced 20 tons of particulates and 23 tons of carbon monoxide last year as well. Most of that pollution occurred during handling and travel along the unpaved dirt roads next to the plant.
The Acme plant, equipped with a baghouse emissions-reduction system, produces about 3 tons of particulates per year, said environmental engineer Kelle Vigeland.
Because of new federal air control programs, Acme officials had to either become a “registered source” and set an annual production limit or apply to join the new EPA operating-permit program.
Acme, which has operated its North Side plant for many years, opted for the first choice.
“It’s more complicated and costly to enter the operating permit program,” said Vigeland.
Comments to SCAPCA should be made in writing, Vigeland said. Those who have questions should call 456-4727, extension 106.
Vigeland said no one has yet offered a comment on the Acme regulation. Most of the plant’s neighbors are industrial sites.
If Acme officials want to produce more than 300,000 tons a year, they will have to apply for eligibility through the EPA’s new-source regulatory program.
The Acme plant operates during the fall, spring and autumn and closes for part of the winter.
