HILCORP ALASKA, LLC
LEWIS RIVER UNIT

The Alaska Department of Environmental Conservation (ADEC) proposes to issue an Owner Requested Limit approval (ORL) AQ1913ORL01 to Hilcorp Alaska, LLC for the Lewis River Unit under Alaska Statute 46.14 and regulation 18 AAC 50.

Applicant: Hilcorp Alaska, LLC, 
3800 Centerpoint Dr., Suite 1400, 
Anchorage, AK 99503

Location: Western Side of Cook Inlet, AK

Activity: Limit emissions with non-selective catalytic reduction to avoid a minor permit. 

Emissions:  The change in emissions at the stationary source will not exceed 10 tons per year of NOX potential emissions increases by operating the new EU ID 15 with non-selective catalytic reduction, thereby staying below the minor permitting threshold under 18 AAC 50.502(c)(3). The other regulated criteria pollutants (PM10, PM2.5, SO2, and CO) remain below the thresholds listed in 18 AAC 50.502(c)(3) with or without the limit. 

ADEC Preliminary Review:  Based on review of the application, ADEC has made a preliminary decision to approve the ORL for the Lewis River Unit.

Available Information: Copies of the ORL application and ADEC’s preliminary approval are available at the following offices:
