This permit shall be effective from the date of issuance until rescinded and shall be subject to the conditions and limitations as specified therein. This cover letter shall be considered a part of this permit and is therefore incorporated therein by reference. 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 2T .0403 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 2T; 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 Permittee's responsibility to ensure that the as -constructed project meets the appropriate design criteria and rules. Failure 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.

The Extension will consist of approximately 448 if of 2-inch piping to connect wastewater from the subject residence to an existing 4-inch grey wastewater system. The wastewater flows for the new line will generate approximately 0.2 gpm (average daily flow), using a peak factor of 2.5, the peak flow will generate 0.5 gpm, therefore the pump flow of 40.5 GPM will be utilized at the given conditions rate required to meet a velocity of 4 fps above the minimum 2 fps. A 2-inch force -main outside of the lift station was used for this design to convey the projected wastewater flow. PRO.TF,CTET3 T,OA1MNG: The Average Daily Flow (ADF) ONSTTP.
