Colorado 80203 Tel (303) 839-3567 <br />David C. Shelton <br />august 6, 1981 Director <br />TO: Coal Staff <br />FROM: Bob Liddle <br />RE: Application of Sludge to Reclaimed Areas <br />In consultation with the Colorado Department of Health and MLRD staff, I have <br />prepared the following document which outlines the procedures and requirements <br />mine operators should follow to obtain approval from ~~fL.4D for sludge utilization <br />on land. Compliance with this document does not relieve the operator from <br />compliance with the Performance Standards of Rule 4, or any other local, State, <br />or Federal Iaw. <br />Sect: on 2.07,7(2) requires that the disposal of sludge be made to insure <br />compliance with the Performance Standards of Rule 4 and which prevents violation <br />of any other applicable State or Federal law. In a meetinc between MLRD and <br />representatives of the Department of Health .on July 17, 1981, the questions of <br />jurisdiction over sludge disposal was discussed. Gregory Starhebaum of the <br />Colorado Hazardous [tastes Control Division indicated that Mined Land Reclamation <br />now has final jurisdiction over the disposal~of waste at minine operations due <br />to a recently passed bill, Don Simpson of the Colorado [Dater 7uality Control <br />Division indicated that his Division has no enforcement authority over the <br />utilization of sludge on Land. However, they do request tha[ such disposers <br />voluntarily comply with Department of Health guidelines in anticipation of <br />regulations to be promulgated in the future under C.R.S. 1973 30-20-101 et. sue. <br />Richard Fox of the Colorado Air Pollution Control Division indicated that <br />dust and odor produced from the sludge is covered under his Division's regu- <br />lations. However, if the sludge is applied and covered properly and only a smaI1 <br />amount is stored on site, there should not be any oreat problem with the practice <br />unless a citizen reports the practice as a nuisance, As a result of [his .:.eeting, <br />it was decided that MLRD would review the sludge utilization request in ccrsul- <br />tation with the Depa rtmen[ of Health. <br />The general procedure for obtaining approval from .NERD is as follows: <br />a. Obtain and submit a "letter of approval" from the De partrent o` Health, <br />Water Quali CU Con [rot Division. <br />b. Contact the Colorado Air Pollution Control Division to Setermine what, <br />if an u, information will be needed to bring the existing air quality permit into <br />compliance. Document that this has been accomplished either by a Setter from <br />APCD which states not:~ing is reouired, or a cony of the revised application! <br />permit. <br />c. If it was not covered in the original permit, the applicant should provide <br />a discussion of Che probable hydrologic consecuences of the activity (Rule 2). <br />
