The proposed work consists of the replacement of 80 linear feet (If) of subsurface gas main on Sea Side Village Road and 90 If of subsurface gas main on South Shore Drive. The work is located within Land Subject to Coastal Storm Flowage (LSCSF). The location of the project area is depicted on the Site Location Map included as Attachment A. The proposed work is exempt from the Town of Yarmouth Wetlands Protection Regulations (Section 1.02.2-3(b)), which states "The applications and approvals required by these regulations shall not be required for maintaining, repairing, or replacing, but not substantially changing or enlarging, an existing and lawfully located structure or facility used in the service of the public to provide electric, gas, water, telephone, telegraph, or other telecommunication services, provided that written notice has been given to the Conservation Commission prior to commencement of work, and provided that the work conforms to any performance standards and design specifications in regulations adopted by the Commission." A similar exemption is provided under the Massachusetts Wetlands Protection Act regulations at 310 CMR 10.02(2)(a)2. This letter is intended to serve as the required written notice of exempt work. In general, the gas replacement activities will entail the excavation of an approximately two- foot-wide trench for safe installation. The trench bottom will be excavated and graded such that the pipe will be supported for its entire length on undisturbed bottom at a depth of approximately three feet below surface grade. The trench will be excavated within the existing impervious surfaces of Sea Side Village Road and South Shore Drive and adjacent sidewalks, with the precise location of the gas line to be determined in the field so that existing utilities can be avoided. Upon installation of the replacement line, the trench will be backfilled and restored in-kind. No direct impacts to wetland resource areas are anticipated as a result of this project. This work is primarily within the existing paved road and sidewalk areas. Best Management Practices (BMPs) will be implemented as needed. Attachment B of this submittal includes details of standard erosion control measures that have been used in past projects of similar scope. Following the completion of construction activities, disturbed areas will be restored in- kind. nationalgrid Please refer to the attached Site Location Map for the project location.
