Requested modifications or variances to the Minimum Design Criteria will be reviewed on a.case-by-case basis and each on its own merit. Please note that variances to the Minimum Design Criteria should be requested and approved during the permitting process prior to construction. After -construction requests are discouraged by the Division and may not be approved, thus requiring replacement or repair prior to certification & activation. [15A NCAC 02T .0116] 8. Gravity sewers installed greater than ten percent below the minimum required slope per the Division's Gravity Sewer Minimum Design Criteria shall not be acceptable and shall not be certified until corrected. If there is an unforeseen obstacle in the field where all viable solutions have been examined, a slope variance can be requested from the Division with firm supporting documentation. This shall be done through a permit modification with fee. Such variance requests will be evaluated on a case -by -case basis. Resolution of such request shall be evident prior to completing and submitting the construction certification. [ 15A NCAC 02T.0105(n)] 9.

The proposed design includes approximately 360 linear feet of 2" force main sanitary sewer and 630 linear feet of 4" gravity sewer line to serve a diving pool with equipment room and a small restroom. Diving pool, equipment room, and restroom to be constructed now. The design also includes one pump station serving multiple buildings to pump sewer effluent under whitewater channel and up to existing sanitary sewer manhole where the effluent discharges to the existing gravity system on site. This pump station carries flow from small restroom and pool backwash system.t Wastewater will be treated by Charlotte -Mecklenburg Utilities. Please do not hesitate to contact me if you have any questions.

Certification Statement: I Carl Wilson certify to the best of my knowledge that the addition of the volume of wastewater to be permitted in this project has been evaluated along the route to the receiving wastewater treatment facility and that the flow from this project is not anticipated to cause any capacity related sanitary sewer overflows or overburden any downstream pump station en route to the receiving treatment plant under normal circumstances, given the implementation of the planned improvements identified in the planning assessment where applicable. This analysis has been performed in accordance with local established policies and procedures using the best available data. This certification applies to those items listed above in Sections I and II plus all attached lanning assessment addendums for which I am the responsible party. Signature of thi/fprm indicates acceptance of this wastewater flow. 011417 I 0 Date Page 2 of 6 FTSE 08-13 FTSE PLANNING ASSESSMENT ADDENDUM (PAA) Submit a planning assessment addendum for each pump station listed in Section II where Available Capacity is < O.

The proportion and amount of Obligated, Not Yet Tributary Daily Flow (C) accounts for 1.6 (Long) , 1.2 (Paw)% ando• 066, 0.066 MGD of the Available Capacity (E) in Pump Station Long Creek and Paw Creek ;and that b. The rate of activation of this obligated, not yet tributary capacity is currently approximately o . 066, 0 . 066 MGD per year; and that c. A funded Capital Project that will provide the required planned capacity, namely Long Creek EQ Basin and Paw Creek Forcemaain ReplacementiS in design or under construction with planned completion in Long Creek, Completand/or d. The following applies: Paw Creek - 2020 CMUD's Capital Improvement Plan has allocated funds for improvements to the Paw Creek forcemain and a 5 million gallon EQ basin at Long Creek Pump Station. Long Creek and Paw Creek pump stations operate as a system using SCADA data to determine the rate of flow delivered from the upstream pump station, Long Creek, to Paw Creek the downstream facility. Long Creek pump station has the ability to transfer flows to flow equalization tanks during peak flow events and then meter out flow to paw creek as flow conditions allow. In addition, the basins for both stations are large and result in a daily peaking factor of 2.06 at Paw Creek Pump Station, which allows the stations to operate safely at flows greater than 40% of the firm pumping capacity. 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. I understand that this does not relieve the collection system owner from complying with G.S. 143-215.67(a) which prohibits the introduction of any waste in excess of the capacity of the waste disp+s : stem.

Center Avenue Suite 301 Mooresville, NC 28115 Re: Fast -Track Application for Gravity Sewer Cover Letter Dear Sir or Madam, The enclosed application is for a sewer line extension at the US National Whitewater Center facility in Charlotte, North Carolina. The proposed design includes approximately 630 linear feet of 6" gravity sewer line to serve a diving pool with equipment room and a small restroom. Diving pool, equipment room, and restroom to be constructed now. The design also includes one pump station serving multiple buildings to pump sewer effluent under whitewater channel and up to existing sanitary sewer manhole where the effluent discharges to the existing gravity system on site. This pump station carries flow from small restroom and pool backwash system. Wastewater will be treated by Charlotte -Mecklenburg Utilities. Please do not hesitate to contact me if you have any questions. Sincerely, Sarah Stewart, PE 361i :\ h.
