Hanes Mill Road Suite 300 Winston-Salem, NC 27105 RE: Fast Track Sewer System Extension Permit Modification Eden Remediation Program — Junction and Bridge Street Pump Stations Rehabilitation City of Eden, North Carolina WKD Project No. 20120031.01.11A Dear Mr. Henderson: The City of Eden plans to rehabilitate both the 5 MGD Bridge Street Pump Station and the 11 MGD Junction Pump Station.The submitted application below is meant to cover the rehabilitation of both pump stations as part of the remediation project. The overall Eden Remediation Program aims to repair or replace damaged sewer, reduce inflow and infiltration, and ultimately extend the reliability and longevity of the City of Eden's collection system. Slight adjustments to the force main,to accommodate the proposed valve vaults, are occurring with this project, but the gravity sewer leading to each pump station is not being affected by the work at the pump stations. Rehabilitation or replacement of portions of the gravity sewer upstream or downstream of either um station may be occurring, and that work is included in the pump y g, appropriate phases, previously submitted for approval. We are requesting that a modification be made to the sewer collection system permit WQCS00018 to allow for the rehabilitation of the pump stations as included herein. The Junction Pump Station lies inside the floodway of the conjunction of the Smith and Dan Rivers and the Bridge Street Pump Station lies inside the flood plain of the Dan River. Variances for the location of the pump stations have been submitted to the Central Office of DEQfor review. Both pump stations were originally constructed prior to the mapping of flood hazards in this area. As part of this submittal, please find enclosed the following documents for the referenced permit modification: • One (1) original and one (1) copy of the Fast Track Sewer System Extension Application (FTA 04-16) • One (1) check made payable to the North Carolina Department of Environmental Quality (NCDEQ) in the amount of$480.00. 720 Corporate Center Drive Raleigh, NC 27607 Tel.919.782.0495 www.wkdickson.com Transportation • Water Resources • Urban Development • Geomatics Mr.Henderson July 29,2019 Page 2 • Two (2)copies of 8.5-inch by 11-inch color copies of the USGS Topographic Map covering both pump stations depicting the location of the pump stations and closest surface waters • Two (2) copies of street level maps (aerial) showing general project location for each pump station • Two (2) copies of the most recently issued existing permit for the collection system Please do not hesitate to contact us if you have any questions or comments.

The Division will grant the variance requests for the upgrades of the Junction Street Pump Station, in accordance with the provisions for alternative design under 15A NCAC 02T.0105(n): 1. Pursuant to the variance request received on May 31, 2019 from W.K. Dickson & Co., Inc., on behalf of the City of Eden,a variance is granted for the construction and operation of the upgrades to the Junction Street Pump Station, located within the 100-year floodway of the Smith River,as indicated on the provided plans and supplementary documentation: a. Per the provided plans and supplementary documentation,the proposed upgrades shall include the following items: i. Watertight hatches on the existing wet well. ii. All electrical components and the on-site generator shall be located a minimum of 2-feet above the 100-year flood elevation. Ill. The valve vault shall be constructed to be watertight. 2. An alternative design is approved for the existing Junction Street Pump Station's access roadway, located within the 100-year flood elevation and which shall be surfaced with asphalt for improved access, in accordance with the provided plans and supplementary information. 3. An alternative design is approved for the fuel source for the generator located at the Junction Street Pump Station, which shall be served by a natural gas line rather than on-site fuel storage as required by the Minimum Design Criteria, in accordance with the provided plans and supplementary information. Regardless of the variance approval, in the event that the wastewater collection facilities fail to perform satisfactorily, including the creation of nuisance conditions,the Permittee shall take immediate corrective action,including those as may be required by this Division, such as the construction of additional or replacement facilities. = North Carolina Department of Environmental Quality I Division of Water Resources _ 512 North Salisbury 5"et 11617 Mail Service Center I Raleigh,North Carolina 27699-1617 919.7Q7.9000 City of Eden—WQC500018 August 9,2019 All other elements of this project shall be constructed in accordance with all applicable rules and statues including, 15A NCAC 2T,the Division of Water Resources' (Division)Gravity Sewer Minimum Design Criteria adopted February 12, 1996 as applicable;and the Division's Minimum Design Criteria for the Fast-Track Permitting of Pump Stations and Force Mains adopted June 1,2000 as applicable.
