eh <br />ESPEY, HUSTON & ASSOCIATES, INC. <br /> <br />2.0 METHODOLOGY <br />2.1 MONTTORING SITES <br />The existing monitoring sites shown in Fig. H-2 were installed in <br />December of 1977 and January of 1978. The locations for the monitoring equipment <br />were selected to show the impact of the existing mining activity and to determine <br />site-specific background for future expansion of the Meeker Area Mines. Since the <br />existing and proposed mine surface activity is in a nazrow canyon, it was necessary <br />to locate anemometers to measure wind speed, wind du•ectioa and temperature at <br />each end of the canyon. The monitoring equipment for total suspended particulate <br />(TSP) was also located at each end of the canyon to measure the impact of the <br />existing mining. The State of Colorado also operates a TSP monitor located in <br />downtown Meeker, Colorado. <br />I <br />The sites for these monitors and the installation of the equipment meet <br />the requirements for Prevention of Significant Deterioration of Air Quality (PSD) <br />monitoring (Federal Register, 1979)• <br />2.2 METEOROLOGICAL EQUIPMENT <br />The meteorological equipment utilized at both stations is the Meteoro- <br />logical Reseazch Incorporated (MRZ) Model 1071. The continuously monitored wind <br />speed, wind direction, temperature and precipitation data from stations are recor- <br />ded on pressure-sensitive strip chazts. The meteorological sensors are mounted at a <br />height of at least 10 meters from the ground in order to reduce the influence of <br />ground level wind turbulence. <br /> <br />x-s <br />_</ __~.•'y~.'ll!//.~-~!~1) f1~ //i \1> 1 .r 1. vll \ ( Ir ~ / ~Jti _ r•~ 1 ~•J <br />
