Mane Doklovic, PE Variance to Gravity MDC The City of Concord requests a variance to allow an existing 6-inch line ductile iron constructed pre- 1970 become a public line. Rules require a 8-inch minimum public line, The line will serve 10 SFRs in Chelsea Park Subdivsion and Barber Street and Scotia Avenue, The piping in the proposed subdivision will be 8-inch and connect to this 6-inch line, While the 6-inch line is DI, there is an 8-inch PVC water line underneath the sewer line, It is noted in the transmittal sheet that this water line is only for fire flow purposes and would be inactive otherwise. SUMMARY— A variance is granted to allow use of the existing 6-inch ductile iron pipe to serve a maximum of nine lots in the Chelsea Park subdivision and one lot on Barber Street and Scotia Avenue. No additional connections shall be made to this line without prior approval from the Division, Additionally, if the existing 8-inch PVC water main located less than 18-inches below the existing sewer is used for anything other than fire flow purposes, it shall be replaced with ferrous pipe material meeting water main standards, Non -Discharge Permitting Unit 1617 Mail Service: Center, Raleigh, NC 27699-1617 DENR Customer Service Center An Equal Opportunity Action Employer Internet http.//h2o enr.state.nc.ustndpu Telephone (919) 733-5.083 Fax (919) 715-61).48 Telephone 1 800 623-7748 50% recycled/1 O% post -consumer paper Chelsea Park Variance 'W1000030681 Subject: Chelsea Park Variance - WQ0030681 From: Marie Doklovie <Marie Doklovierd)nernail net> Date: Fri, 18 Aug 2006 15:29:16 -0400 To: Dee Browder <t)ee.Browdergnemail.net> Please Print for file and cut- and Paste Thanks!
