After - Page 6 of 8 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] S. 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.

Certification Statement: I Chris Rollins 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 planning assessment addendums for which I am the responsible party. Signature of this form certifies that the receiving collection system or treatment works has adequate capacity to transport and treat the proposed new wastewater.

Sullins Governor Director March 15, 2011 Robert L. Wilson City Manager City of 106 Eastt Washington Street k Mebane, NC 27302 Subject: Mebane WWTP (NC0021474) 1` Flow Reduction Request Alamance County Dear Mr. Wilson: Dee Freeman Secretary On February 14, 2011, the Pretreatment, Emergency Response and Collection System (PERCS) Unit of the Division of Water Quality received a flow reduction request for connections to the City of Mebane WWTP. The letter requests an allowable flow rate of 80 gallons per day (gpd) per bedroom based on the evaluated data. As daily WWTP data is not representative of the project area, the DMR data from the City of Mebane WWTP (NC0021474) from January 2009 through December 2009 was evaluated to determine the peak sewage month. The highest flow month was December 2009. Daily wastewater flows were recorded downstream of the Holly Ridge Subdivision during December 2010. This data was reviewed by PERCS and Regional Office staff. Based on the data, the Division hereby grants a reduction in flow to 80 gpd/bedroom (minimum of 160 gpd for 1 and 2 bedroom residences) for sewer extension permits issued tributary to the City of Mebane WWTP. Regardless of the adiusted design daily wastewater flow rate at no time shall the wastewater flows exceed the effluent limits defined in the NPDES permit for the treatment facility or exceed the capacity of f the sewers downstream of any new sewer extension or service connection(s) If you have any questions or comments regarding this matter, please contact Sarah Morrison at (919) 807-6310, or email [Sarah.
