e <br />ESPEY, HUSTON & ASSOCIATES, INC. <br /> <br />Z.0 MONTfORING <br />As required under 30 CFR 784.26, Northern is proposing to install and <br />operate an air quality monitoring system that replaces the system that was <br />described in Chapter H: Climotology -Air Quality. This system will be operated to <br />monitor all operations from the complex of the Meeker Area Mines and is described <br />below. Northern is requesting approval of this plan as required under 817.95(d). <br />2.1 INTRODUCTION <br />The area to be monitored by the proposed air quality and meteorological <br />stations include the Northern No. 1 {FF-Seam) loadout, the Rienau No. 2 (G-Seam) <br />mine, and Northern No. 2 (P-Seam) and Northern No. 3 (J-Seam) Mines. State <br />• Highway 13/789 skirts the western edge of the disturbed azea boundary, approxi- <br />mately 31 miles south-southwest of Craig. The sites selected should be indicators of <br />how the flow over the disturbed azea would transport pazticulates from the mining <br />activity. This proposal will be formulated on the assumption that electrical power <br />will be supplied at all sites. <br />2.2 SITE SELECTION <br />Wind flow patterns in this region aze largely determined by the rugged <br />topography. State Highway 13/789 runs through the bottom of a valley at an <br />elevation between 6,900 and 6,950 feet above mean sea level (AMSL). The disturbed <br />azea covers ground that extends to both sides of State Highway 13/789. The highest <br />point closely corresponds to the Northern No. 1 (FF-Seam) loadout location at an <br />elevation of approximately 7,200 feet AMSL. Locating near the mountain peaks <br />would make access almost impossible and would not accurately monitor the wind <br />flow patterns over the disturbed area. The sites should be above the steepest <br />section of the grade where orographic channeling is greatest in order to monitor <br />• <br />N-3 <br />
