' INTRODUCTION <br /> ' The Eagle #5 and #6 Mines are underground coal mines, located <br /> approximately seven miles south of Craig, Colorado (Figure 1) . <br /> ' The aerial extent of the underground workings in the #5 Mine was <br /> approximately 2 , 040 acres at the end of 1989. Approximately 87 <br /> acres had been mined in the #6 Mine at the end of 1989. The coal <br /> being mined is from the Cretaceous Age Williams Fork Formation, "F" <br /> Seam in the #5 Mine and the "E" Seam in the #6 Mine. <br /> ' Hydrologic monitoring has been conducted at the mine site since <br /> 1980. This report presents the results of the 1989 monitoring. <br /> The complete 1983 , 1984 , 1985, 1986, 1987, and 1988 monitoring is <br /> ' presented in the respective Annual Reports. <br /> The hydrologic monitoring is divided into two parts: 1) ground <br /> ' water, and 2) surface water. The monitoring locations are shown <br /> in Figure 2 and summarized in Table 1. The water quality <br /> ' monitoring includes field parameters (Table 2) , water quality <br /> parameters (Table 3) , and NPDES parameters (Table 4) . The water <br /> ' quality samples are analyzed by ACZ Laboratories, Inc. , Steamboat <br /> Springs, Colorado, a USEPA certified laboratory. This report <br /> ' includes data collected specifically to meet requirements of the <br /> Colorado Mined Land Reclamation Division (CMLRD) , as well as data <br /> collected to meet the requirements of the Colorado Wastewater <br /> ' Discharge Permit System (NPDES permits) . A complete listing of all <br /> the water quality data is submitted separately. <br /> 1 <br />
