The modification requested is the reduction of unit count from 63 Townhomes to 61 Townhomes. The project has not installed any infrastructure to date and no portions of the sewer have been certified to date. No other modifications to the original permit are requested. The project remains as an 8" sanitary sewer system to serve the proposed residential community comprising of townhomes and single family homes. The proposed change will reduce the anticipated flow to add a total of 17,920 GPD of wastewater to the existing system and connects to existing sanitary sewer system under permit number WQ003943. • Cover Letter • Original Fast Track Application Form • Copy of Fast Track Application • GIS Map • Street Level Map • Application Fee of $600.00 • Flow Tracking Form • 401/404 Permit • Flow Reduction Approval It is noted in Section IX. (3) of the Fast Track Application that this project does not meet the 50 feet of separation requirement from existing wetlands. Due to the existing features of this site, there are locations around the existing wetlands where the sanitary sewer could not be relocated to meet the 50 ft requirement. In accordance with 15A NCAC 2T .0305(f), the proposed sanitary sewer is designed to maintain maximum feasible separations when a 50 foot separation could not be met. The design has been reviewed and approved by Union County Public Works.

Total actual and obligated flows to the facility, MGD Equals [d + e + f] h. Percent of permitted flow used: Equals [(g / c)* 100] For example: On January 15 a POTW with a permitted flow of 6.0 MGD, reported to the Regional Office that there is 0.5 MGD of flow that is obligated but not yet tributary. The annual average flow for 2007 is 2.7 MGD. There is a proposed flow expansion of 0.015 MGD. The first Form FTSE submitted after January 15, 2008 may have numbers like this: c. = 6.0 MGD d. = 0.5 MGD e. = 2.7 MGD f. = 0.015 MGD g. = 3.215 MGD h. = 53.6 % The next Form FTSE may be updated like this with a proposed flow expansion of 0.102 MGD: c. = 6.0 MGD d. = 0.515 MGD e. = 2.73 MGD f. = 0.102 MGD g. = 3.349 MGD h. = 55.8 % Section II List the pump station name or number and approximate pump station firm capacity, approximate design average daily flow (A) approximate current average daily flow (B), and the obligated, not yet tributary flow through the pump station (C) for each pump station that will be impacted by the proposed sewer extension project. Calculate the total current flow plus obligated flow (D=B+C) and the available capacity (E=A-D). Include the proposed flow for this project with other obligated flows that have been approved for the pump station but are not yet tributary (C). Firm capacity is the maximum pumped flow that can be achieved with the largest pump out of service as per the Minimum Design Criteria. Design Average Daily Flow is the firm capacity of the pump station divided by a peaking factor (pf) of not less than 2.5.

A planning assessment for Kaw Creek PS (see example data above) may be performed to evaluate whether there is significant likelihood that needed improvements or reductions in obligated flows will be in place prior to activating the flows from the proposed sewer extension project. If the system decides to accept the flow based on a planning assessment addendum, it is responsible to manage the flow without capacity related sanitary overflows and must take all steps necessary to complete the project or control the rate of flow to prevent sanitary sewer overflows. The planning assessment may identify a funded project currently in design or construction, or a planned project in the future not yet funded but in a formal plan adopted by the system. The system should carefully weigh the certainty of successful timely project completion for any expansion, flow management diversion or infiltration and inflow elimination projects that are the foundation of a planned solution to capacity tracking and acceptance compliance. For example: Given that: a. The proportion and amount of obligated, not yet tributary flow accounts for 24 % and 0.080 MGD of the committed flow in Pump Station Kaw Creek; and that b. The rate of activation of this obligated, not yet tributary capacity is currently approximately 0.01 MGD per year; and that c. A funded capital project that will provide the required planned capacity, namely is in design or under construction with planned completion in ; and/or d. The following applies: The master plan and ten year capital plan contain recommended scope and funding for a capital project entitled Kaw Creek Pub Station upgrade with funding planned in July 2014 This project is planned to add 0100 MGD to the firm capacity of thepumpstation by October 2015 Inclusion of this proposed capital project as a condition of this Flow Tracking/Acceptance for Sewer Extension Permit Application elevates this project's priority for funding and construction to be implemented ahead of the activation of obligated not vet tributary flows in amounts that exceed the firm pump station capacities identified in Section II above. Therefore: Given reasonably expected conditions and planning information, there is sufficient justification to allow this flow to be permitted, without a significant likelihood of over -allocating capacity in the system infrastructure. 1� r/ 1,r � ��� if r � /��^� •'� I �• J � 1 t�� � � z O N O � y P B R 5 2 0 0 m 11 __ pearl st 46 S if C 0 7 U-1 LU St LI I uj 99, J(7 M ci CL co- CL 0 L) 4.1 Chutrh 10 7 i7 OinLio S 0 cia s Bro. 13f gad 51 Bf,ad S, N ogl) St MICHAEL S.
