Salisbury. Rowan County. NC Dear Sirs: On behalf of my client, Ms. Darlene Blount of Forest Glen, Inc., I am requesting your review of the enclosed plans to obtain a Nationwide Permit 918 to install a drain pipes and rip-rap apron in wetlands below headwaters. I have also attached a letter from the civil engineer regarding attempts to minimize impacts. This includes sizing the rip-rap apron to discharge at a minimum slope and minimum velocity to avoid erosion. The total impacts required to conduct this activity is approximately 0.03 acres. Approximately .077 acres will be required to install a temporary sediment trap below each flared end section. As pointed out in the letter, these temporary facilities will be removed and the area will be restored to its original grade and revegetated with hydrophytic vegetation. The developer is also requesting the opportunity to modify small disturbed pockets in wetlands below headwaters of approximately .04 acres to remove ruts and regrade a stagnant area along an existing dirt road. The total impacts requested utilizing Nationwide Permit #18 is approximately 0.07 acres. Throughout the development of this project, Forest Glen Inc. has taken special care to prevent impacts to this large and important wetland complex on this site. Clearly marked construction limits and barricades shall be used to prevent additional disturbances or accidental encroachments. The developer is also aware that these impacts will be evaluated cumulatively and cannot be used to increase the total wetland fill allowed under Nationwide Permit #26 if it is used in headwater areas in the future. In addition to the Nationwide Permit #18 request, an authorization to utilize NWP #12 is being requested to connect this phase of Forest Glen to an existing sanitary sewer trunk line on the opposite side of Grant's Creek. As depicted on the plan the crossing is perpendicular to the Grants Creek. The alignment through the wetlands has been designed on the ground to minimize impacts to specimen bottomland hardwoods of willow oak, swamp chestnut oak, and green ash. Clearing is proposed to be the minimum possible and will not exceed 40'. The proposed area of disturbance utilizing NWP #12 is approximately .15 to .20 acres. Mr. Steve Chapin - USACE, Mr. John R Dorney - NCDWQ Water Quality Planning Forest Glen - NWP 18 & 12 Page 2, March 24, 1997 PROPOSED AVOIDANCE, MESEMEIZATION, AND MITIGATION The developer has pursued extensive professional planning input to develop this project while maintaining sensitivity to environmental concerns. Preliminary planning involved site analysis and consideration of environmental and regulatory issues. Once the final extents of the wetland areas were determined, a very strong effort, as depicted on the plan, was made to adapt the plan to avoid and minimize disturbance to wetlands to the extent feasible. Except for temporary construction and development impacts we believe that the proposed project will not cause significant impacts to the ecological functions or values of Jurisdictional Waters of the U. S.. Minimization The sewer line project will be designed and constructed to conform to the Corps of Engineers Nationwide Permit 12 or Regional Permit 049 (Utility Line Backfill and Bedding) and the North Carolina Division of Environmental Management General Certification Conditions - September 6, 1995. The topsoil shall be saved through the disturbed area and the top 6" to 12" of the trench will be backfilled with this topsoil to encourage rapid re-establishment of previous vegetation conditions. The contours throughout the area of disturbance will also be restored immediately upon the completion of construction. An annual species suitable for wet locations will be planted within jurisdictional wetlands for soil and erosion control. Perennials such as fescue will not be specified. The above and remaining Nationwide Permit and 401 Water Quality Certification conditions which includes the following will be incorporated into the plans and specifications of the project: a) Written concurrence from NCDEM is required if the utility be is installed parallel to and closer than 10 feet to a stream or if the utility line crosses a stream channel at less than 75 degrees or more than 105 degrees of the stream bank; b) Construction corridors parallel to streams shall be placed at the furthest distance from the stream to the maximum extent possible; C) That established sedimentation and erosion control practices are utilized to prevent violations of the appropriate turbidity water quality standards. All sedimentation and erosion control measures placed in wetlands shall be removed and the natural grade restored after the Division of Land Resources has released the project, d) Annual species suitable for wet locations shall be planted within jurisdictional wetlands for soil and erosion control. Perennials such as fescue are prohibited; e) No fertilizer shall be applied within 10 feet of streams; f) The construction corridor (including access roads and stockpiling of materials) is limited to 40 feet in width and must be minimized to the maximum extent practicable. g) Measures shall be taken to prevent live or fresh concrete from coming into contact with waters of the state until the concrete has hardened; ? r Mr. Steve Chapin - USACE, Mr. John R Dorney - NCDWQ Water Quality Planning Forest Glen - NWP 18 & 12 Page 4, March 24, 1997 h) Permanent, maintained access corridors shall be restricted to the minimum width practicable and shall not exceed 10 feet in width except at manhole locations. A 10 feet by 10 feet perpendicular vehicle turnaround must be spaced at least 500 feet apart. i) An anti-seep collar shall be placed at the downstream (utility line gradient) wetland boundary and every 150 feet up the gradient until the utility exits the wetland for buried utility lines. Anti-seep collars may be constructed with Class B concrete or compacted clay. Compacted clay shall have a specific discharge of 1 X 10 -5 cm/sec or less. D Placement of rip rap is restricted to stream bottoms and banks directly impacted by the placement of the utility line. The stream berm must be restored to the original contours after construction; k) This general certification does not authorize any permanent changes in preconstruction elevation contours in waters or wetlands. The permitee will have a specific plan for restoring wetland contours. Any excess material will be removed to a high ground disposal areas. Best Management Practices will also be employed to minimize impacts to Jurisdictional Waters. This will include: Siltation Barriers Sediment Traps and Diversion Ditches - Barricades to define construction limits to sensitive sites and to protect trees - Preconstruction meetings - Other methods as appropriate - Vehicular access will be restricted to specific areas to avoid disturbance to adjacent wetlands and natural areas to be preserved. Methods to prevent short term impacts will be inspected regularly and maintained during construction of the project. Wetlands to be clearly marked prior to construction to prevent accidental damage to wetlands. The contractors will be held responsible for unauthorized wetland damage not permitted according to plans and specifications. Preconstruction meetings shall be held if necessary with representatives of the USACE and the NCDWQ. Short term construction impacts, primarily stream sedimentation will affect aquatic habitat, however this will be minimized to the extent practicable to promote rapid recovery. Project construction will strictly adhere to an approved Sedimentation and Erosion Control Plan. Best Management Practices will include utilizing siltation trapping ponds and other erosion control structures where appropriate. Impacts from hazardous materials and other toxins to fish and aquatic life such as fuels will be avoided by not permitting staging areas to be located near surface waters. Also, as required by the 401 Water Quality Certification conditions, measures will be taken to prevent "live" or fresh concrete from coming into contact with waters until the concrete has hardened. ? r Mr. Steve Chapin - USACE, Mr. John R Dorney - NCDWQ Water Quality Planning Forest Glen - NWP 18 & 12 Page 3, March 24, 1997 Wetland areas in temporarily saturated soils or subject to occasional and brief inundation -TY Rate April 1 - Jul. 15 Red Top Grass 7 lbs/acre Smartweed 20 lbs /acre Jul. 16 - Sept. 1 Temporary Crop Jap.
