-: <br />New Castle Energy Corporation <br />July 9, 1986 <br />Mr. Jeff Deckler <br />Reclamation Specialist <br />Mined Land Reclamation Division <br />423 Centennial Building <br />1313 Sherman Street <br />Denver, CO 80203 <br /> <br />JUL i u 'iJC•~ <br />~~ ;.. ~ ., <br />RE: Your Comments to NCEC's 1985 Annual Hydrology Report, <br />Coal Ridge No. 1 <br />Dear Mr. Deckler: <br />NCEC has reviewed your memo of June 4, 1986, to Mr. Mike Fisher <br />regarding the 1985 Annual Hydrology Report. This letter answers <br />all of your questions and comments. we are not able to answer <br />some of your questions since personnel has changed significantly <br />over the past year. We may be able to answer these concerns once <br />the mine becomes operational again and an environmental <br />specialist is hired. Please note that monthly hydrologic <br />monitoring is still being performed at the mine site. <br />NCEC's comments to your questions are as follows: <br />1. Missing field data, primarily pH and conductivity, are mainly <br />due to faulty equipment. There have been instances when measur- <br />ing equipment has failed in the field and repairs could not be <br />effected in time to obtain that current months' reading. NCEC <br />will continue to endeavor to take all the required readings. It <br />should be noted that data previous to 1985 had been included in <br />our permit. <br />One monitoring well, SK-3.75, has been difficult to monitor on <br />a consistent basis. This hole is on the south side of the Grand <br />Hogback and is difficult to access during inclement weather or <br />during the winter due to snow build-up. Every effort will be <br />made to obtain samples from the well. <br />2, Data sheets for dry wells will be included in the 1986 Annual <br />Hydrology Report. <br />New Castle Energy Corporation • 9137 East Mineral Circle • Englewood, CO 80772 • (303) 792-2625 <br />
