Dept. of Natural Resources <br /> <br />Re: July 29, 1981 Telephone Conversation <br />Dear Mike: <br />On July 29, 1981, I contacted you regarding confirmation of <br />the adequacy of the sediment control structures at the Chimney <br />Rock Coal mine site. <br />You may recall that. the provisions of our recently approved <br />NPDES permit require a demonstration that the aforementioned <br />structures meet the containment requirements. Such demon- <br />stration must be submitted to the Water Quality Control <br />Division by November 16, 1981. The specific requirements <br />are described on an attachment hereto. <br /> <br />This is a friendly reminder in the event that it may have <br />escaped your memory. <br />If you need any additional information, please don't hesitate <br />to contact me. <br />Sincerely, <br />Rade H. Drell <br />Environmental Supervisor <br />RHO/pks <br />Enclosures <br />
