In general, the responses are considered adequate; however, some <br />minor concerns are listed below. <br />1. It seems that only 10 of the 12 required field parameter measurements <br />were obtained for surface site 09243800, and only 11 of the 12 required <br />field parameter measurements were obtained for surface site 09243900. <br />Please review your data records and incorporate any additional available <br />data. Please be sure that all 12 required analyses are obtained in the <br />future. <br />2. The revisions made to Map 14 A are adequate; however, the maps were not <br />signed by your engineer. Please be sure that future submittals contain <br />the required signature and certification. <br />3. We request that the next Annual Hydrology Report does contain a graph of <br />electrical conductivity for Station 800. This information would be a <br />helpful supplement to the information already included, because flow is <br />intermittent at Station 14. <br />Thank you.,for your continued cooperation, <br />Si nre~ely~i' <br />;~' ~~~f. <br />/ l/"i <br />Davi~ Berr <br />`Recla 'on Specialist <br />DAB/1 j t <br />cc: Mike Savage <br />and please call with any questions. <br />1678E <br />215 Centennial Building, 1313 Sherman Street Denver, Colorado 802032273 Tel.
