" Please pay particular attention to Permit Condition 3 which requires that the wastewater collection facilities be properly operated and maintained in accordance with 15A NCAC 2H .0227 or any individual system -wide collection system permit issued to the Permittee. Permitting of this project does not constitute an acceptance of any part of the project that does not meet 1) 15A NCAC 2H .0200; 2) the Division of Water Quality's (Division) Gravity Sewer Minimum Design Criteria adopted February 12, 1996, as applicable; 3) and the Division's Minimum Design Criteria for the Fast -Track Permitting of Pump Stations and Force Mains adopted June 1, 2000, as applicable, unless specifically mentioned herein. Division approval is based on acceptance of the certification provided by a North Carolina -licensed Professional Engineer in the application. It shall be the Perrnittee's responsibility to ensure that the as -constructed project meets the appropriate design criteria and rules. Faittrre to comply may result in penalties in accordance with North Carolina General Statute §143-215.6A through §143-215.6C, construction of additional or replacement wastewater collection facilities, and/or referral of the North Carolina -licensed Professional Engineer to the licensing board. aro tna uralily Mooresville Regional Office 610 East Center Ave., Suite 301 Mooresville, NC 28115 Phone: (704) 663-1699 Fax: (704) 663-6040 Internet h2o.enr.state.nc.us Customer Service: 1-877-623-6748 An Equal Opportunity/Aftinnative Action Employer - 50% Recycled/10% Post Consumer Paper VaigaMt/Mk .

The additional information requested from the owner in order to process the request was received 8/16/05. The Water and Sewer Authority of Cabarrus County (WSACC) has or currently expects to be able to make available capacity at the Rocky River Regional Wastewater Treatment Plant and. appropriate sewer interceptors to transport and treat the domestic wastewater from the proposed Bridge Point Subdivision Phase 1 & .2 consisting of 57 residential lots, WSACC agrees to accept wastewater from the proposed sewer line based on information provided by The Isaacs Group, P.C. (Civil Engineer for the project) using North Carolina Department of Environment and Natural Resources (NCDENR) wastewater flow guidelines. The projected flow is 20,520 gpd; however WSACC expects the actual wastewater flow to more closely approximate 14,250 gpd based upon Master Plan engineering data. The Town of Harrisburg understands that separate FloAcceptance Requests will be required for the future flows that will connect into this sewer line. By requesting flow acceptance, the Town of Harrisburg acknowledges that WSACC may need to upgrade, expand, or construct new facilities to accommodate the increased flow volume granted by this and previous flow acceptance. Appropriate design and construction will be initiated when actual flows dictate but :may be subject to situations that WSACC does not expect or control. Based upon flow of 20,520 gpd and cost of $8.126/gpd to provide treatment and transportation capacity, this flow acceptance represents an estimated capital expenditure in excess of $166,745. For your information and based upon NCDENR wastewater flow guidelines, WSACC has approved 1,503,537 gallons of flow acceptance for the Town of Harrisburg from 1992 to present and 108,000 gallons of flow acceptance year-to-date including this request. Based upon the approved flow acceptances, WSACC has committed capacity valued in excess of $12,217,741for the Town. of Harrisburg since 1992 including $877,608 for this calendar year. Downstream facilities from the proposed project are scheduled in WSACC's current six year Capital Improvement Program (CIP) to increase available capacity. Projects on the CIP are subject to approval by WSACC's Board of Directors, support from local governing bodies, regulatory T'own of Flarrishurg Bridge Pointe SubdivIsion Phase 1 & 2 August 19, 2005 Page -2- approval, and funding availability. The following schedule of CIF delayed by unforeseen circumstances: • Back Creek Interceptor Parallel Phase 1. Scheduled completion • Fuda Creek Interceptor.
