VIII. ASII DISPOSAL <br />During 1990, a total of 32,451 tons of mixed fly and bottom ash was <br />dumped in A Pit (east end). All of this ash came from Coors' Power <br />• Plant in Golden and was 80% Colowyo, 10% MacIntyre stockpile, and <br />10% Keenesburg stockpile coal. A sample of fly ash and a sample of <br />bottom ash has been taken at the power plant and analysed by <br />Saturated Paste Extract and by Toxicity Characteristic Leaching <br />Procedure (TCLP) and is included on the following pages. From <br />the mass balance cross sections, it appears that there is room in A <br />Pit for five more years of Coors' ash. <br />IX. SOIL SAMPLE <br />No topsoil was replaced during 1990, therefore, the sample normally <br />submitted has not been taken. <br />• <br />u <br />Page 11 <br />
