Nuiqsut Air Quality Monitoring Station Annual Trends Analysis Report, 2019

ConocoPhillips Alaska Inc. (CPAI) operates an ambient air quality and meteorology monitoring station in Nuiqsut, Alaska, which is located on the Alaska North Slope. The monitoring program consists of an ambient air quality monitoring station and a meteorological monitoring tower directly mounted to the air quality monitoring structure. The program is designed and operated in accordance with applicable Prevention of Significant Deterioration (PSD) regulations and guidance documents.

The specific project objectives of the Monitoring Program are to:

• Collect data to document Nuiqsut air quality and address community concerns related to regional oilfield development.

• Establish a monitoring system to measure, with known accuracy and precision, meteorological parameters at the project site from ground level up to 10 meters.

• Provide required and relevant optional meteorological data for American Meteorological Society/Environmental Protection Agency (EPA) Regulatory Model Improvement Committee Model (AERMOD) modeling system.

• Establish a monitoring system to measure, with known bias and precision, the ambient concentrations of the criteria air quality pollutants: ozone (O3), carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), particulate matter (PM) with an aerodynamic diameter of 10 microns or less (PM10), and particulate matter with an aerodynamic diameter of 2.5 microns or less (PM2.5) to establish National Ambient Air Quality Standards (NAAQS) compliance status for the monitoring location.
