Sullins Dee Freeman Governor Director Secretary May 5, 2011 Rolf Blizzard, Manager Pine Island - Currituck, LLC 615 Hillsborough St., Suite 201 Raleigh, NC 27604 Subject: Permit No. WQ0018170 Modification Pine Island - Currituck, LLC Pine Island - Currituck, LLC (Wastewater Collection System Extension to serve The Currituck Club, Phase 8A and Lot 430) Sewer - Modification Wastewater Collection System Extension Currituck County Dear Mr. Blizzard: In accordance with your permit modification application received April 19, 2011 and additional information received May 3, 2011, we are forwarding herewith Permit No. WQ0018170, dated May 5, 2011, to Pine Island - Currituck, LLC for the continued construction and operation of the subject wastewater collection system extension. This permit shall be effective from the date of issuance until rescinded, shall void Permit No. WQ0018170 dated October 4, 2006, and shall be subject to the conditions and limitations as specified therein. This cover letter shall be considered a part of this permit and is therefore incorporated therein by reference. 1) This modification clarifies the names of the owner and the facility, as well as increases the design flow of the Phase 8A section (previously named Cottages) by 480 gallons per day (GPD). The section was previously designed as 16 7-bedroom Lots, but due to larger homes not selling, the section has been redesigned as 29 4-bedroom Lots. The Phase 8A modification reduces pump station (PS) number (#) 21, from duplex 151 gallon per min (GPM) pumps to 150 GPM pumps. (Note: PS # 21 serves only the 13,920 GPD design flow for Phase SA.) The total design flow for the Phase 8A/Inn Site/Historic Lots section therefore increases by 480 GPD, previously permitted with a total section design flow of 49,560 GPD, to the increased total section design flow of 50,040 GPD. The line length was previously permitted for 1,408 linear feet (LF) of 4-inch force main (FM). The redesigned smaller lot sizes for the Phase 8A section reduces the design length to 1,176 LF of 4-inch FM. 2) This modification adds Lot # 430 to the Phase 1 section. The Lot is located at the end of Herring Gull Court and increases the section's design flow by 480 GPD. The Currituck Club PUD Phase I and Phase 2 and Magnolia Bay - Phase 1 total section design flow was previously permitted as 98,400 GPD. Lot # 430 increases the section's total flow to 98,880 GPD. Note: The flow of Lot # 430 is made North Carolina Division of Water aua ty Internal wwwn2Mergualityorg 943 Washington Square Mali Phone: (252) 946.6461 e 7�T j y Washington, NC 27889 Fax: (252) 946.9215 lr c CaroHxa aturallrf An Equal OpportunitylAMirmaGve Action Employer— 50'k Recycledll0°r6 Post Consumer Paper tributary via a deemed service connection (Additional sewer length permitting is not included for the connection). 3) Therefore, this modification increases the total design flow by 960 GPD as accounted above. Although, the Engineer has requested for the entire Pine Island - Currituck, LLC system flow allocation be reduced from the previously permitted 543,160 GPD to the total development allocation of 541,628 GPD. The Aquifer Protection Section of the Washington Regional Office has agreed to allow the revised total. Please pay particular attention to Permit Condition 3 which requires that the wastewater collection facilities be properly operated and maintained in accordance with 15A NCAC 2T .0403 or any individual system -wide collection system permit issued to the Permittee. Permitting of this project does not constitute an acceptance of any part of the project that does not meet 15A NCAC 2T; the Division of Water Quality's (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, unless specifically mentioned herein. Division approval is based on acceptance of the certification provided by a North Carolina -licensed Professional Engineer in the application. It shall be the Permittee's responsibility to ensure that the as -constructed project meets the appropriate design criteria and rules. Failure to comply may result in penalties in accordance with North Carolina General Statute § 143-215.6A through § 143-215.6C, construction of additional or replacement wastewater collection facilities, and/or referral of the North Carolina -licensed Professional Engineer to the licensing board.
