State of North Carolina Department of Environment, Health, and Natural Resources Division of Environmental Management 512 North Salisbury Street ® Raleigh, North Carolina 27604 James G. Martin, Governor William W. Cobey, Jr., Secretary October 21,1991 Mr. Walter Reynolds Greene Engineering, P.E. 709 Plaza Bldv Kinston, NC 28501 Dear Mr. Reynolds George T. Everett, Ph.D. Director As I mentioned in our telephone conversation of Friday October 19, 1991, the technical support branch is currently involved in renewal of NPDES permit number NC0044750, for Britthaven of Madison. A request for a modification of the permit (relocation of discharge and increase in waste flow) was also received. An allocation for oxygen -consuming waste at the new waste flow and location must be calculated, however, the branch has no current flow data for the new location on Hogans Creek. An estimate of flow has been made and it appears the current limits will be sufficient to protect water quality in that area with the possible exception of NH3-N and residual chlorine. This, of course, is a preliminary finding based on an estimate of flow. Currently, a flow request has been submitted to the U.S. Alogical Survey and the wasteload allocaiton will be completed upon receipt of that flow data. Thank you for telephone call and should you need any further information please feel free to call me at 919-733-5083 ext. 510. Sincerely, Norman J.
