This review is for the modification of the existing Starmount Pump Station Permit(W00021392).This project includes the replacement of 1,058 LF of 8"gravity sewer and the addition of 814 LF of 8"gravity sewer.448 LF of 8° gravity sewer will remain undisturbed. The planned limits of disturbance are approximately 1.93 acres. Once the sewer is permitted, built, and certified,the Town of Clayton will decommission the pump station. The Regional Office will be notified to perform a site inspection to verify the new sewer exists and is in use, as well as that the pump station has been shut down. We look forward to hearing from you regarding this review.

Town of Clayton Flow Reduction Approval Johnston County Dear Mr.Biggs: On January 3, 2001, the Division of Water Quality received your flow reduction request for new single-family dwellings in the Town of Clayton. The letter requests approval of a residential flow value of 250 GPD/residence for any future dwellings that may become tributary to the subject wastewater collection system. The Division also received additional information on April 3,2001 The information provided flow records between January 1998 and November 2000 for the WWTP. The evaluation also included the daily wastewater flows for a 33 day period from February 19 through March 23, 200I for a select 97 homes in accordance with 15A NCAC 2H .0219(l)(3). Based upon the information submitted, the Division hereby approves the use of 250 GPD per single- family residence in all applicable non-discharge permit applications for future sewer line extensions for the Town of Clayton. This consideration applies to any applicable future projects submitted to the Division as well as any projects which are currently under review.
