NC 28211 704/542.7317 Environmental Management Raleigh, N.C. 27611 Re: Request for Effluent Limit Determination Dear Ms. Kerr: 63a7 1 t On behalf of our client, Carolina Water Service, Inc., we respect- fully request determination of effluent discharge limits for a proposed project on McKee Creek in Mecklenburg County for flows of 150,000 GPD 300,000 and 600,000 GPD. Two copies of a USGS map showing the location of the proposed discharge are enclosed. It is our understanding that the current backlog of work in your division is extensive and we can expect approximately 6-8 weeks elapsed time before receiving the limits. We would appreciate a phone call relaying the results of your preliminary findings as they are available. Very Truly Yours, Dale C. Stewart, P.E.
