c. <br /> oF-Col <br /> COLORADO DEPARTMENT OF HEALTH <br /> • Richard D.Lamm 1, �N ~��` Frank A.Traylor,M.D. <br /> Governor I g 6 Executive Director <br /> August 18, 1981 <br /> Mr. Doug Bowman <br /> Mid Continent Resources <br /> Box. 158 <br /> Carbondale CO 81623 <br /> Dear Mr. Bowman: <br /> This letter is to clarify matters of concern regarding permit and compliance <br /> status for Mid Continent Resources Dutch Creek mining operation. As was <br /> discussed in our phone conversation this morning, no permits .are required <br /> for sources of air pollution .that existed prior to February. 1, 1972, which <br /> was the effective date of the air pollution .emission regulation requiring <br /> emission permits. Sources commencing construction or operation after the <br /> above date do require the issuance of an air pollution emission permit from <br /> the Air Pollution Control Division. <br /> • Also requiring emission permits are existing sources which increase emis- <br /> sions of any air pollutant to the atmosphere. For the purposes of determin- <br /> ing these increases, the Division policy is one of requiring new permits for <br /> emission increases greater than 10% above existing levels. <br /> As the regulations pertain to the Mid-Continent Resources' operation, my <br /> last on-site inspection occurred. on July 23, 1980. At that time all appli- <br /> cable rules and regulations covering air pollution emissions plus all permit <br /> requirements on sources for which they are required were being complied with. <br /> If you have any other questions or need additional clarification, please call <br /> me. <br /> Sincerely, <br /> Scott J., 'ller <br /> Air Pollution Control Division <br /> SJM/zp <br /> cc: Denver Office <br /> 0 <br /> Grand Junction Office: 125 N. 8th St. #10, Grand Junction CO 81501 245-2400 <br /> 4210 EAST 11TH AVENUE DENVER,COLORADO 80220 PHONE (303) 320-8333 <br />
