This acceptance of flow is based upon the existing capacity of the designated publicly owned treatments works. Please find FTSE document attached. Charlotte Water(CLTWater) agrees to furnish water to the subject project. The water quality to the subject project is regulated by the State Drinking Water Act Amendments of 1986 and The Water Supply Management Plan, PWS ID#0160010 on file with the Public Water Supply Section of NCDEQ. However, CLTWater cannot guarantee a constant pressure or quality of flow. The applicant should understand that due to the involvement of other agencies and continuing growth of the water system, the ability to provide service for future projects cannot be guaranteed nor reserved. Connection to the CLTWater system is accepted on a first come first served basis. The applicant should understand that this letter is not authorization to construct or extend private water or sewer systems, as the appropriate local or State permits are required prior to construction. If the appropriate authorization to construct permits are not obtained construction has not started within two(2) years of issuance of this flow acceptance and payment for any service connections have not been received within two(2)years of issuance of this flow acceptance letter this flow acceptance approval shall be rescinded and a new flow acceptance request must be made.

Hunt, Jr., Governor Jonathan B. Howes, Secretary A. Preston Howard, Jr.,-P.E., Director February 13, 1995 Barry M. Gullet,F.E., Deputy Director Charlotte-Mecklenburg Utility Department 5100 Brookshire Boulevard Charlotte,North Carolina 28216 RE: Charlotte Mecklenburg Utility Department Reduction in Wastewater Flows Mecklenburg County Dear Mr. Gullet: On July 20, 1994,the Division received your wastewater flow reduction request and support documentation concerning wastewater flows associated with the entire Charlotte-Mecklenburg Utility Department service area. Your letter requested the Division allow the reduction of wastewater flows from 250 GPD per dwelling unit which was previously approved in accordance with North Carolina Administrative Code,to 190 GPD per dwelling unit for single family residential areas and 135 GPD per -.-dwelling._unit.for.multi-family residential areas..In support of your request,documentation was provided from the existing Irwin, Sugar,and McAlpine Creek wastewater treatment plant service areas. The documentation provided in support of the flow reduction request was compiled by Camp Dresser&McKee starting in late 1990 and is currently ongoing. Data submitted to the Division was not in strict accordance with 15A NCAC .0219(1)(3),however,in view of the submitted documentation, adequate justification was provided in support of the wastewater flow reduction request. The work completed by Camp Dresser&McKee consisted of tracking base wastewater flows,groundwater infiltration,and rainfall-dependent infiltration/inflow for the Irwin, Sugar, and McAlpine Creek wastewater treatment plant service-areas. Data was collected from 106 flow monitors(both permanent and temporary)and 14 rain gauges during November and December 1991 located along major sewer trunklines within the study area. Existing dry-weather flows were developed for each of the three(3)wastewater treatment plant service areas which included groundwater infiltration. The service area dry-weather flow estimates were further broken-down into thirteen(13)drainage basins. These revised dry-weather flow estimates were compared to land-use based flow estimates developed using existing land data for 446 . Origination and Destination(O&D)planning zones as provided by the City of Charlotte's Department of Transportation. From this comparison the revised wastewater flows were developed. Although these numbers were developed for Irwin, Sugar, and McAlpine Creek service areas,the results would also be applicable to both the Mallard Creek and McDowell Creek wastewater treatment plant service areas. In view of the information submitted,the Division of Environmental Management will allow the use of 190 GPD per dwelling unit for single family residential areas and 135 GPD per dwelling unit for multi-family residential areas on all applicable non-discharge permit applications for future wastewater collection extensions which will be made tributary to all five(5)Charlotte-Mecklenburg Utility Department wastewater treatment facilities. This consideration applies to any applicable future projects submitted to this Division as well as any projects which are presently under review. Wastewater flows presently tributary to the wastewater treatment facilities can be adjusted upon negotiations between the Charlotte- Mecklenburg Utility Department and the Division's Mooresville Regional Office. P.O.Box 29535, Raleigh,North Carolina 27626-0535 Telephone 919-733-7015 FAX 919-733-2496 — An Equal Opportunity Affirmative Action Employer 50%recycled/10%post-consumer paper Page l Charlotte-Mecklenburg Utility Department February 13, 1.95 The Division does have concerns regarding the proposed sewage flow rates with respect to infiltration and inflow. Although the 190 GPD per dwelling unit for single family residential areas and 135 GPD per dwelling unit for multi-family residential areas are justifiable flow rates,the Charlotte- Mecklenburg Utility Department has in essence reduced the safety factor typically associated with infiltration and inflow. The flow rate established by the Division does allow for some infiltration and inflow. The Division is of the opinion that proper wastewater collection system management is more effectively and efficiently accomplished by the entity that is accountable for ensuring overall compliance with all aspects of wastewater collection,treatment, and disposal requirements. In this view,we look forward to continued progress by the Charlotte-Mecklenburg Utility Department to fully assume the wastewater collection permitting program. ents regarding this matter,please contact Mr.Michael D.Allen If you have any questions or comm at(919)733-5083.
