APCD extends Gregory Canyon comment period

The Air Pollution Control District has issued a 30-day extension for public comments on its proposed Authority to Construct permit for the Gregory Canyon landfill.

The public comment period began July 5 and was originally slated to end on Aug. 5, but that day the APCD issued a notice that the written comment period would be extended to Sept. 4.

“We had a lot of requests to extend it. It’s a complicated project,” said APCD senior engineer Steven Moore.

The extension allows for more comprehensive review by interested parties. Additionally, the APCD revised its preliminary Authority to Construct conditions and the extra time allows for public analysis of those changes.

The APCD received about 15 comments during the first 30-day period. “Most of them are on the order of if we’d extend the comment period and things like that,” Moore said.

The total Gregory Canyon property is 1,770 acres, including 308 acres which will be used for landfill activities and 183 acres for the actual landfill footprint where waste will be deposited. APCD staff evaluated the air pollution impacts of the proposal and determined that the landfill would operate in compliance with all applicable APCD rules and regulations and all applicable Federal requirements the APCD is authorized to implement. The preliminary permit includes conditions which will ensure compliance with all Federal, state, and APCD regulations under APCD control. “We made a preliminary decision basically,” Moore said.

The preliminary permit conditions limit new equipment to a maximum of 16.4 tons per year of oxides of nitrogen, 43.8 tons per year of oxides of sulphur, 39.7 tons per year of carbon monoxide, 49.5 tons per year of volatile organic compounds, and 95.0 tons per year of particulate matter less than or equal to 10 microns in diameter.

The APCD will review the public comments and provide official responses prior to making its final decision on the Permit to Construct. “We’re going to consider all the comments we get,” Moore said.

The APCD will also require a Permit to Operate, which must be applied for within one year of the start of construction.
