PROJECT SUNLN ARY: The proposed project involves municipal wastewater treatment plant improvements including the construction of new structures and demolition of existing structures. All work will be done at the site of the existing wastewater treatment plant. Field Investigation Report: Morehead City Wastewater Treatment Plant Page 02 9) Narrative Description: The project is located at the existing wastewater treatment plant in the Town of Morehead City, Carteret County at the end of Treatment Plant Rd. Treatment Plant Rd. is found by taking a left on to Mayberry Loop Rd. off of N. 20`h St. Calico Creek borders the site along the southwest property line. This property is 16 acres in size and ranges from 0' to 7' above NHW. Currently on the *site there exists the Morehead City municipal wastewater treatment plant. All roads and utilities along with discharge pipes that serve the plant are in place. Running along the southwest side of the site is Calico Creek. Between the creek and the shore there is a fringe of Smooth Cordgrass (SSpartina alterniflora) that is approximately 100' wide. The shore then transitions to a thin fringe of high coastal marsh and Section 404 wetlands. The vegetation on the high.ground area includes; Live Oak (Quercus vir ing iana), Sweet Gum (Liquidambar stryciflua), Loblolly Pine (Pinus taeda) and Wax Myrtle (Myrica cerifera). Most of the high ground is graded and planted with grass. Residential neighborhoods border the property on either side. The Division of Water Quality classifies Calico Creek as SA. This area of the creek is a Primary Nursery Area but is. not open to the taking of shellfish. Carteret County's Land Use Plan dated 1996 classifies this area as Developed and Conservation within the AEC's. There are no shellfish . leases in this area. The. applicant applied for a sedimentation contibl plan through the Division of Land Resources on 1/17/06. A site development plan was submitted to the Division of Environmental Management on 12/23/05. 10) Project Description: The Town of Morehead City is proposing a renovation of its existing wastewater treatment plant. The project proposes to construct new plant structures and demolish some existing structures. All work would be done at the existing plant site. During the renovation of the wastewater treatment plant the following components and buildings will be constructed, eventually becoming the new treatment facility; -Aerated grit removal structure (18'X18'X16'tall) -Dual oxidation diteches (310'X130'X16'tall) -Dual secondary clarifers (70' dia X 3' above ground) -Dual tertiary filters (70'X44'X4' above ground) -Dual chlorine contact and post aeration chambers (43'X60'X5' above ground) -Influent Pump Station (18'X28') -Sludge Return Pump Station (18'X34') -Electrical Building (18'X29') -Chlorination/De-Chlorination Building (30'X30') -Sludge Storage Building (100'X180') This process will disturb a maximum of 14 acres. The project would result in a total of 6.19% impervious area within the 75' Estuarine Shoreline AEC. Once the new structures are operational, the older structures would then be taken off line and demolished. Field Investigation Report: Carteret Community College Page 03 --------------------------- 10. Anticipated Impacts: The Morehead City municipal wastewater treatment plant would provide additional capacity to the City's sewer system. The existing discharge pipes would be used and there is no proposed development in or over coastal wetlands so no disturbance to coastal wetlands is expected. Appropriate sedimentation and erosion control measures will be employed during construction to prevent runoff during.ground disturbing activities. Impervious area within the Estuarine Shoreline AEC will increase from 3.71% to 6.19%. Impervious area on the entire site will increase from 6.35% to 12.61% Name James Ryan Davenport Date 3/22/06 Morehead City Form DCM-MP-1 A_P,.1DLffCATff0N (To be completed by all applicants) 2noS0527 1.
