This project is being conducted in compliance with the Massachusetts Wetlands Protection Act(WPA; MGL Ch. 131 § 40),the Massachusetts Wetlands Protection Regulations(MWPR; 310 CMR 10.00 et seq.) and the City of Salem Wetlands Protection Ordinance(Chapter 50). Refer to WPA Form 1 which is included as Appendix 1. The purpose of the 100± linear foot(If)gas service connection(the"Project Route")project is to provide a new 1.25-inch 100 pounds per square inch gauge(psig)natural gas service connection to a Massachusetts Bay Transportation Authority(MBTA)track switch heater. The proposed project will be located within the 100-foot buffer zone to Coastal Beach and the 200-foot Riverfront area to the North River. In reviewing the proposal with the City of Salem Conservation Agent, it was concluded that this work should be filed as an RDA pursuant to the WPA and the Bylaw. 1.2 Existing Site Conditions The Project Route consists of a 100±If corridor primarily in the paved right-of-way(ROW) to Sergeant James Ayube Memorial Drive(approximately 650 feet north of the intersection with Bridge Street). Surrounding areas consist of primarily residential development. The service connection will be made from an existing natural gas main along the bike path and will extend across Sergeant James Ayube Memorial Drive to the MBTA property. A review of the current Massachusetts Geographic Information System(MassGIS)data layer for the Natural Heritage and Endangered Species Program's(NHESP)Massachusetts Natural Heritage Atlas(13s' Edition,October 2008)indicates that the Project Route is not located within an Estimated Habitat of Rare Wildlife or Priority Habitat of Rare Species. No certified vernal pools under the jurisdiction of the Wetlands Protection Act Regulations or the Massachusetts Endangered Species Act(321 CMR 10.00 et seq.) are located along the Project Route(See Figure 3 -NHESP Map). According to the July 2014 Federal Emergency Management Agency(FEMA)Flood Insurance Rate Map for Middlesex County, the Project Route is located within a FEMA Special Flood Hazard Area X, defined as an"area determined to be within the 0.2% annual chance floodplain"(See Figure 4-FEMA Map). The Project Route is not located within an Area of Critical Environmental Concern (ACEC)or within an Outstanding Resource Water (ORW). Wetland resource areas are described in the following section. Photographs representative of existing conditions in the vicinity of the proposed Project Route are included in Appendix 2. CONECO ENGINEERS &SCIENTIST'S, INCORPORATED IOA Sergeant James Ayube Memorial Drive RDA June 30,2016 Salem,Massachusetts Page 2 1.3 Wetland Resource Areas An Environmental Scientist conducted a wetland reconnaissance along the Project Route on May 13,2016 to identify wetlands, watercourses and other resource areas subject to local, state, and federal jurisdiction. Areas within 200 feet of the Project Route were reviewed. A formal delineation was not completed. The reconnaissance was conducted in accordance with the WPA and Regulations; the Bylaw and Bylaw Regulations; and the Clean Water Act. Methods follow the technical guidance outlined in Delineating Bordering Vegetated Wetlands Under the Massachusetts Wetlands Protection Act:A Handbook(1995); the Corps of Engineers Wetlands Delineation Manual(1987);the Regional Supplement to the Corps of Engineers Wetland Delineation Manual:Northcentral and Northeast Region (Version 2.0, 2012), and others, as applicable. Jurisdictional resource areas were identified in the vicinity of the Project Route. The resource areas comprised Bordering Land Subject to Flooding, Coastal Beach and Riverfront Area, which are defined as follows: Bordering Land Subject to Flooding—310 CMR 10.57 310 CMR 10.57 defines Bordering Land Subject to Flooding as an area which floods from a rise in a bordering waterway or water body. Such areas are likely to be significant to flood control and storm damage prevention and provide temporary storage areas for flood water which has overtopped the bank of the main channel of a creek, river, or stream or the basin of a pond or lake. Coastal Beach—310 CMR 10.27 310 CMR 10.27 of the WPA defines Coastal Beach as unconsolidated sediment subject to wave, tidal and coastal storm action which forms the gently sloping shore of a body of salt water and includes tidal flats. Coastal beaches extend from the mean low water line landward to the dune line, coastal bankline or the seaward edge of existing human-made structures, when these structures replace one of the above lines, whichever is closest to the ocean. Riverfront Area—310 CMR 10.58 The Riverfront Area is the area of land between a river's mean annual high-water line measured horizontally outward from the river and a parallel line located 200 feet away. The Mean Annual High Water line of a river is the line that is apparent from visible markings or changes in the character of soils or vegetation due to the prolonged presence of water and that distinguishes between predominantly aquatic and predominantly terrestrial land. Field indicators of bankfull conditions shall be used to determine the mean annual high-water line. Bankfull field indicators include but are not limited to: changes in slope, changes in vegetation, stain lines, top of pointbars, changes in bank materials, or bank undercuts. The approximate locations of the resource areas and buffer zones are shown in Figures 5 - Resource Area and Best Management Practices (BMP)Map. These resource areas and buffer zones, while based on MassGIS data, appear to be generally representative of field conditions. CON ECO ENGINEERS$ SCIENTISTS, INCORPORATED I OA Sergeant James Ayube Memorial Drive RDA June 30,2016 Salem,Massachusetts Page 3 2.0 PROPOSED WORK DESCRIPTION 2.1 Introduction Proposed construction will occur entirely within the roadway ROW of Sergeant James Ayube Memorial Drive,the adjacent earthen shoulder, and a small portion of the asphalt bike path. The proposed gas service connection will connect the existing gas main within the bike path and will extend west to a proposed MBTA track heater adjacent to the existing railroad tracks. The Project Route will be located within the 100-foot buffer zone to Coastal Beach, and the 200-foot Riverfront Area to the North River(Figure 5 -Resource Area and BMP Map). Construction associated with the project will occur within previously developed areas,and disturbed areas will be restored to previous conditions (to the extent practicable)upon completion of work. 2.2 Erosion Control To guard against potential impacts from the proposed natural gas service connection, erosion and sedimentation control BMPs consisting of a straw wattle secured by wooden stakes (or an approved equivalent) will be installed between the edge of the work area and the identified resource areas,as necessary(depicted in Figure 5). In addition, silt sacks will be installed for inlet protection (e.g., catch basins), along Sergeant James Ayube Memorial Drive, as necessary. Details of proposed BMPs are included in Appendix 3. 2.3 General Construction Details The following is a general construction sequence for the installation of the proposed natural gas service project. The sequence of construction may vary slightly as necessary to assure completion of the overall project. General Construction Sequence: 1. Sediment controls will be installed in the vicinity of the Project Route, as necessary. The majority of the Project Route is constructed with a curb and gutter storm water management system. Proposed work will be performed within the paved ROW,the adjacent earthen shoulder, and a small portion of the asphalt bike path; therefore, catch basin inlet protection will be installed as necessary along the Project Route. Additionally, straw wattles will be installed between the Project Route and adjacent resource areas. 2. Pavement will be saw cut to the dimensions of the excavation. This will vary from 1- 2 feet in width with larger excavations at junctions or where ancillary equipment will be installed. 3. Soil will be excavated to a depth of 2-4 feet and either sidecast (deposited temporarily adjacent to the excavation)or into a dump truck. CONECO ENGINEERS& SCIENTISI S, INCORPORATED i IOA Sergeant James Ayube Memorial Drive RDA June 30,2016 Salem,Massachusetts Page 4 4. A gravel bed will be laid within the trench to cradle the pipe. 5. New pipe(approximately 1.25-inch diameter plastic)will be laid in the trench and connected to the existing natural gas main. 6. The trench will be backfilled either with the excavated soil or with clean fill as necessary at the end of each work day and covered with steel plates or temporary/permanent bituminous pavement. During this process caution tape is left above the pipe to alert future workers of the existence of the pipe. No excavated soil will be left on-Site at the conclusion of each work day. 7. The road will be repaved, following existing contours. Disturbed, grassed areas (if any)will be seeded(grass seed) and maintained by the property owner. 8. Project area cleanup and erosion control removal will include proper disposal of any surplus soil or other materials. 3.0 REGULATORY COMPLIANCE As a result of the proposed work, there will be impacts within the 100-Foot Buffer Zone, and the 200-foot Riverfront Area. These impacts are temporary, and the proposed work area will be returned to pre-existing conditions(to the extent practicable)upon completion of the installation. The project is not anticipated to result in impacts to adjacent Resource Areas. Proposed work qualifies as a Limited Project under 310 CMR 10.53(3)(d)of the WPA regulations: The construction, reconstruction, operation and maintenance of underground and overhead utilities, such as. natural gas lines, may be permitted...Proposed work also qualifies as a Minor Activity Project under 310 CMR 10.02(2)(b)(2)(i)of the WPA regulations. 1 It is also important to reiterate that all work is temporary in nature, and that all areas of disturbance will be returned to their pre-existing condition(to the extent practicable) following completion of work. :With the use of appropriate sediment control BMP's, no adverse effect is anticipated relative to any resource area or buffer zone. 4.0 SUMMARY A 100± if natural gas service connection is being proposed along Sergeant James Ayube Memorial Drive in the City of Salem. The purpose of the proposed project is to provide a new gas service connection to an MBTA track switch heater. Portions of the project lie within the 100-Foot Buffer Zone to Coastal Beach and the 200-foot Riverfront Area to the North River,and temporary impacts are anticipated in these areas. Proposed work qualifies as a Limited Project under 310 CMR 10.53(3)(d)and a Minor Activity Project under 310 CMR 10.02(2)(b) of the Wetlands Protection Act. Given this designation,the fact that impacts are temporary in nature and limited to previously developed areas, and the proposed employment of sediment control BMP's to protect adjacent resource areas during CONECO ENGINEERS&SCIENTISTS, INCORPORATED l0A Sergeant James Ayube Memorial Drive RDA June 30,2016 Salem,Massachusetts Page 5 construction, Coneco (on behalf of BGC)respectfully requests that the City of Salem Conservation Commission issue a Negative Determination(boxes c and d), allowing the gas service connection project to proceed as proposed.

The overall purpose of such controls is to prevent and control the movement of disturbed soil and sediment from work sites to adjacent, undisturbed areas, and particularly to water resources, public roads and adjacent properties. All proprietary controls shall be installed per manufacturer's recommendations and specifications. Appropriate sedimentation and erosion control devices include but are not limited to: silt fencing, straw bales, wood chip bags, straw wattles, compost socks, erosion control blankets, mulch, slope interruption practices, flocculent powderiblocks and storm drain/catch basin inlet protection. Such controls shall be installed between the work area and environmentally sensitive areas such as wetlands, streams, drainage courses, roads and adjacent property when work activities shall disturb soils and result in a potential for causing sedimentation and erosion. Staked straw bales often serve as the demarcation of the limits of work and/or sensitive areas to be avoided. Work shall never be conducted outside the limit of erosion controls without prior approval from the National Grid Environmental Scientist. Project plans depict proposed erosion controls, however field conditions may warrant additional practices be implemented (e.g., wet conditions, frozen conditions, poorly drained soils, steep slopes, materials used for work pads, transition areas to swamp mats, number of trips across work areas, etc.). Any deviation from the approved erosion controls shown in the EFI and/or SWPPP plans needs to be communicated immediately to the National Grid Environmental Scientist as it may require additional permitting or result in a permit violation. Appendix 7 provides typical sketches of common sedimentation and erosion controls. If a SWPPP is required for the project, maintenance and inspection of erosion controls shall follow the SWPPP requirements. Sedimentation and erosion controls shall be properly maintained and Approved for use per EP 10,Document Control PRINTED COPIES ARE NOT DOCUMENT CONTROLLED.

Inspections shall be documented using the Inspection Form "Storm Water, Wetlands & Priority Habitat Environmental Compliance Site Inspection/Monitoring Report"(Appendix 6). The sequence and timing of the installation of sedimentation and erosion control measures is critical to their success. Sedimentation and erosion controls shall be installed prior to commencing construction activities that may result in any soil disturbance or cause otherwise polluted site runoff. Inspection of these devices may be required by the National Grid Environmental Scientist or by regulators prior to the start of work. The installation of water bars and other erosion control measures shall be installed shortly thereafter. i i II Approved for use per EP 10,Document Control PRINTED COPIES ARE NOT DOCUMENT CONTROLLED.
