.. <br />INTRODUCTION <br />' The Twentymile Coal Company Fish Creek Tipple is located approximately 10 <br />' miles north of Oak Creek, Colorado at the north end of Twentymile Park <br />(Figure 1). The tipple structure and related area cover approximately 70 <br />acres. Denver and Rio Grande Western Railroad tracks run through the site. <br />' lmmediately north of the Tipple is Fish Creek. The site drainage is into a <br />sediment pond (Pond E) which drains northward into Fish Creek. On the site <br />' and south of the site are reclaimed spoils which have been released from <br />bond. <br />' hydrologic monitoring has been conducted in the area since 1979. The tipple <br />' was constructed in 1974 and monitoring related to tipple operations began in <br />1979. This report covers the hydrologic monitoring for the water year <br />1987. October 1, 1986 to September 30, 1987. The previous monitoring of <br />' this area was presented in the 1986 Annual Hydrologic Report. Hydrologic <br />monitoring has been divided into three parts: 1) ground water, 2) surface <br />' water, and 3) discharge site. The monitoring locations are shown on Figure <br />7 and summarized on Table 1. The parameter lists are shown on Table 2 and <br />3. A complete listing of all water data collected at these sites has been <br />submitted separately. Summaries of the complete data set and the 1987 water <br />' year data are presented on Tables 4 to 16 and Figures 3 to 11. <br />flee majority of the monitoring work was conducted by a consultant, Al Miller <br />' of Steamboat Springs, Colorado during the 1986-1987 water year. Presently <br />the monitoring is conducted by Cyprus Yampa Valley Coal Corporation <br />personnel. All of the water quality analyses were performed by ACZ <br />Laboratories (formerly Bookcliffs) of Steamboat Springs, Colorado. Due to <br />' t.lie switch from calendar year reporting to water year reporting and a change <br /> in the scope of the monitoring program in 1981, some stations have <br /> incomplete data sets. The 1988 water year will be the first year with a <br />' complete date data as pe r the requirements of the new monitoring program. A <br /> complete listing of all water quality data for this permit is presented <br />' under separate cover. <br /> <br />CI <br />
