RE: Connection to private pressure sewer system 2393 Castle Hayne Road, Wrightsboro, New Hanover County To Whom it may Concern, Please find attached the following ASEA 04-16 application package which includes all items named on its first four pages essentially being the application, the plan, specifications and supporting calculations for a single duplex pump station connection to the private low pressure system permitted to the Windy Woods Subdivision, WQ0049063. This project proposes retrofit of a network of septic systems that serve five different buildings on two separate properties under common ownership. The waste water flow will be intercepted from each building prior to the existing septic tanks with the provision of individual simplex grinder ejector pump stations each connected independently to a larger duplex pump station that constitutes the connection in solicitation of this permit application. All pumps will be owned and operated by the property owner, Nix Investments 2, LLC. The receiving low-pressure sewer system in the Windy Woods subdivision is permitted to, and will be operated by, Grayson Park Development, LLC. The property is entirely on high ground and well out of the flood plain. There are no wetlands or wells within the vicinity. The project proposes a two-hundred and twenty feet long two-inch force main connection to the Windy Woods low pressure sewer system being comprised of two and three inch PVC pipes that connect to the existing Cape Fear Public Utility Authority,CFPUA gravity sewer system on Olive Street within the Seiter Acres subdivision. The two inch force main proposed by this permit application will discharge directly to a preconstructed two inch service connection into the permitted low pressure sewer system. The connection will include a check and a gate valve. This will be the demarcation of responsibilities between the two operators. Please consider this package complete for permitting. Feel free to contact me should you have any additional needs. Thank you in advance for your attention to this matter. Attachments Respectfully, Cc Bernice Johnson James H. Fentress Jr., P.E.

Mgr 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. J !1 t.
