VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams- Page 9 of 12 USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on January 15, 2002, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http://h2o.enr.state.nc.us/ncN,,-etlands/strmgide.ht". Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. N/A 2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement Program (NCEEP).

Impact Justification This purpose of this project is to provide sanitary sewer service to several existing residential units that are currently being served by a failing sanitary sewer system. The system to be replaced is failing largely because the system does not meet state design standards. The result is a highly unsanitary situation which threatens the health and welfare of the occupants and the environment. The failing system is also creating a situation that has a high potential for sewer overflows/spills. The project, funded by a Community Development Block Grant (CDBG), proposes to install approximately 2,000 linear feet of 8-in gravity sewer line. Sanitary sewer relief is particularly difficult to provide to the units in question. The topography of the area is extremely flat, and satisfactory sanitary sewer infrastructure does not exist in close proximity to the residential units. The implication of these factors is that it is difficult to run sewer lines at state mandated minimum slopes and still maintain sufficient bury depths of the pipes. The proposed sewer alignment was established to minimize the length of pipe required to reach the afflicted units. The minimization of pipe length therefore minimizes the vertical elevation differential between the residences and the nearest receiving sanitary sewer infrastructure. The stream crossing angle of approximately 30° is necessary to reduce the length of the required sewer line. In order to cross the stream at a right angle, an additional run of sewer line would be required. Due to the above mentioned design constraints, the proposed sewer lines have already been designed at the minimum slopes permitted. Therefore, an increase in pipe length that would be required for a 90° crossing would cause the slope to be less than the state minimum require ment. The elevation 'savings' also is just enough to allow the design to comply with state standards for slope. It is important to note that the less-than-ideal crossing angle is not the first design standard casualty in this project. Because the margin for elevation loss is so small and the linear distance so great, significant portions of the gravity line will not have the recommended 3-ft of cover. In fact, at the end of the line, the gravity sewer only has approximately 1-ft of cover. To compensate, the proposed line will be constructed of ductile iron pipe in these areas. Erosion control practices, recommended by the North Carolina Department of Environment and Natural Resources' Land Quality Section will be implemented in the project in order to minimize impacts to the jurisdictional waters. Measures will include sediment fencing, rock check dams (to be located in contributing non-jurisdictional ditches), temporary seeding, and temporary inlet protection. These measures will help to protect and minimize the impact of construction on the project site. Construction practices will include open-cutting of a trench in which the sewer pipe will be laid_ A detail is included in this submittal to demonstrate how the flow in the stream will be maintained so that a dam effect is not generated. It will not be possible to directional bore the pipe underneath the stream, because specific pipe slopes must be maintained, and this is not possible with directional boring. It is important to note that the construction practices will result in only a temporary impact to the stream. Once construction is complete the impacted area will be brought back to existing grade and stabilized.
