(Dominion; NYSE: D), Duke Energy Corporation (Duke Energy; NYSE: DUK), Piedmont Natural Gas Co., Inc. (Piedmont; NYSE: PNY), and AGL Resources, Inc. (AGL; NYSE: GAS). 1 The company was created to develop, own, and operate the proposed Atlantic Coast Pipeline (ACP or Project), an approximately 564.1 -mile -long, interstate natural gas transmission pipeline system designed to meet growing energy needs in Virginia and North Carolina (see Figure 1.1.1-1 in Resource Report 1). The ACP will be capable of delivering up to 1.5 million dekatherms per day (MMDth/d) of natural gas that will be used to generate electricity, heat homes, and run local businesses. The pipeline Project will facilitate cleaner air, increase the reliability and security of natural gas supplies, and provide a significant economic boost in West Virginia, Virginia, and North Carolina. More information is provided at the company's website at www.dom.com/acpipeline. Atlantic has contracted with Dominion Transmission, Inc. (DTI), a subsidiary of Dominion, to permit, build, and operate the ACP on behalf of Atlantic. 2 Atlantic is seeking authorization from the Federal Energy Regulatory Commission (FERC or Commission) under Section 7(c) of the Natural Gas Act to construct, own, operate, and maintain the following proposed facilities for the ACP system: 3 Mainline Pipeline Facilities: AP -1: approximately 300.1 miles of underground 42 -inch outside diameter natural gas transmission pipeline in Harrison, Lewis, Upshur, Randolph, and Pocahontas Counties, West Virginia; Highland, Augusta, Nelson, Buckingham, Cumberland, Prince Edward, Nottoway, Dinwiddie, Brunswick, and Greensville Counties, Virginia; and Northampton County, North Carolina. On August 24, 2015, Southern Company and AGL Resources announced that the boards of directors of both companies have approved a definitive merger agreement. Pursuant to the agreement, AGL Resources will become a new wholly owned subsidiary of Southern Company. The companies expect to complete the transaction in the second half of 2016. As described in this report, DTI actions associated with the ACP are on behalf of Atlantic. Atlantic is also requesting a Blanket Certificate of Public Convenience and Necessity pursuant to Part 284, Subpart G, of the Commission's regulations authorizing open -access transportation of natural gas for others with pre -granted abandonment authority, and a Blanket Certificate of Public Convenience and Necessity pursuant to Part 157, Subpart F, of the Commission's regulations authorizing certain facility construction and operation, certain certificate amendments and abandonments. Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project AP -2: approximately 183.0 miles of underground 36 -inch outside diameter natural gas transmission pipeline in Northampton, Halifax, Nash, Wilson, Johnston, Sampson, Cumberland, and Robeson Counties, North Carolina. Lateral Pipeline Facilities: AP -3: approximately 79.3 miles of underground 20 -inch outside diameter natural gas lateral pipeline in Northampton County, North Carolina; and Greensville and Southampton Counties and the Cities of Suffolk and Chesapeake, Virginia. AP -4: approximately 0.6 mile of underground 16 -inch outside diameter natural gas lateral pipeline in Brunswick County, Virginia. AP -5: approximately 1.1 miles of underground 16 -inch outside diameter natural gas lateral pipeline in Greensville County, Virginia. Compressor Station Facilities: Compressor Station 1 (Marts Compressor Station): a new, natural gas-fired compressor station approximately at milepost 4 (MP) 7.6 of the AP -1 mainline in Lewis County, West Virginia. Compressor Station 2 (Buckingham Compressor Station): a new, natural gas- fired compressor station approximately at MP 191.5 of the AP -1 mainline in Buckingham County, Virginia. Compressor Station 3 (Northampton Compressor Station): a new natural gas- fired compressor station approximately at MP 300.1 of the AP -1 mainline and MP 0.0 of the AP -2 mainline and 0.0 of the AP -3 lateral in Northampton County, North Carolina. Other Aboveground Facilities: Nine new metering and regulating (M&R) stations at receipt and/or delivery points along the new pipelines (including one at Compressor Station 1 and one at Compressor Station 2). Thirty-one valve sites at select points along the new pipelines at intervals specified by U.S. Department of Transportation (USDOT) regulations at Title 49 Code of Federal Regulations (CFR) Part 192. Eight sets of pig launcher and/or receiver sites at 11 points along the new pipelines (including launcher/receiver sites at Compressor Stations 2 and 3). 4 The mileposts used in this report are based on three-dimensional changes in topography (elevation) along the proposed pipeline routes. Therefore, the straight-line distance between two mileposts depicted on two-dimensional maps and figures of the routes may be less than 5,280 feet. The mileposts are reference points along the routes. 10-2 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project As required by 18 CFR 380.12, Atlantic is submitting this Environmental Report (ER) in support of its Application to the Commission for a Certificate of Public Convenience and Necessity (Certificate) to construct and operate the proposed ACP facilities. Supply Header Project DTI proposes to construct and operate approximately 37.5 miles of pipeline loop and modify existing compression facilities in Pennsylvania and West Virginia (see Figure 1.1.1-1 in Resource Report 1). This Project, referred to as the Supply Header Project (SHP), will enable DTI to provide firm transportation service of up to 1.5 MMDth/d to various customers, including Atlantic. Atlantic will be a Foundation Shipper in the SHP, and will utilize the SHP capacity to allow its shippers access to natural gas supplies from various DTI receipt points for further delivery to points along the ACP. By providing its customers access to an affordable and stable source of natural gas, the SHP also satisfies the same purpose and need as the ACP by increasing the reliability and security of natural gas supplies in Virginia and North Carolina. DTI is seeking authorization from the Commission under Section 7(c) of the Natural Gas Act to construct, own, operate, and maintain the following proposed facilities for the SHP: Pipeline Loops: TL -636: approximately 3.9 miles of underground 30 -inch outside diameter natural gas pipeline looping DTI's existing LN -25 pipeline in Westmoreland County, Pennsylvania. TL -635: approximately 33.6 miles of underground 30 -inch outside diameter natural gas pipeline looping DTI's existing TL -360 pipeline in Harrison, Doddridge, Tyler, and Wetzel Counties, West Virginia. Compressor Station Modifications: JB Tonkin Compressor Station: modifications at DTI's existing JB Tonkin Compressor Station in Westmoreland County, Pennsylvania. Crayne Compressor Station: modifications at DTI's existing Crayne Compressor Station in Greene County, Pennsylvania. Burch Ridge Compressor Station: crossover piping at DTI's existing Burch Ridge Compressor Station in Marshall County, West Virginia. Mockingbird Hill Compressor Station: modifications at or near DTI's existing Mockingbird Hill Compressor Station in Wetzel County, West Virginia. Other Aboveground Facilities: One new M&R station at a new delivery point within Atlantic's proposed Compressor Station 1 in Lewis County, West Virginia. Six valve sites at select points along the new pipeline loops at intervals specified by USDOT regulations at 49 CFR 192. 10-3 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project Two sets of pig launcher and receiver sites at the ends of each of the new pipeline loops. DTI is also requesting authorization from the FERC under Section 7(b) of the Natural Gas Act to abandon in place two existing gathering compressor units (Hasting Compressor Units 1 and 2) at its existing Hastings Compressor Station in Wetzel County, West Virginia. As required by 18 CFR 380.12, DTI is submitting this ER in support of its Application to the Commission for a Certificate to construct and operate the proposed SHP facilities. 1.2 BACKGROUND AND APPROACH Cumulative impacts represent the incremental effects of a proposed action when added to other past, present, and reasonably foreseeable future actions. Although the individual impact of each separate action may be minor, the additive or synergistic effects of multiple actions could be significant. The purpose of this analysis is to identify and describe cumulative impacts that could potentially result from construction and operation of the ACP and SHP (collectively, the Projects) when considered in relation to other projects. In accordance with the National Environmental Policy Act (NEPA), the cumulative impacts of the ACP and SHP and other projects or actions in the same areas are considered. This analysis uses an approach consistent with the methodology set forth in relevant guidelines from the Council on Environmental Quality (CEQ) (1997, 2005) and the U.S. Environmental Protection Agency (EPA) (1999). Under these guidelines, the inclusion of actions within the analysis is based on identifying commonalities of impacts from other actions to potential impacts that will result from the Projects. With respect to past actions, CEQ guidance (2005) allows for the adoption of a broad, aggregated approach without "delving into the historical details of individual past actions." That approach is adopted here. The current local or regional landscape in the ACP Project area and SHP Project area forms the environmental baseline against which the impacts of reasonably foreseeable future actions are considered. Recently completed and past projects are considered part of the environmental baseline. Reasonably foreseeable projects that might cause cumulative impacts in combination with the ACP and SHP include projects that are under construction, approved, proposed, or planned. Impacts that are neither direct, indirect, nor reasonably foreseeable do not warrant review under the NEPA. In order to avoid unnecessary discussion of insignificant impacts and projects and to focus the analysis on relevant projects and potentially significant impacts, the cumulative impacts assessment for the Projects was conducted using the following guidelines: Another project must impact a resource category that also is potentially impacted by the ACP or SHP in the same general area as the Projects. More geographically distant projects were not considered because their impacts will generally be localized and, therefore, will not contribute significantly to cumulative effects in the same areas as the Projects. Exceptions are impacts on air quality and watersheds in which cumulative impacts were considered on a broader, more regional basis. 10-4 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project The distance into the past and future that other projects could cumulatively impact the same areas as the Projects is based on whether the impacts are short term, long term, or permanent. The majority of the impacts related to the Projects will occur during the construction phase. Atlantic and DTI are proposing to begin construction in the Fall of 2016, assuming all necessary permits and regulatory approvals are obtained, and placing the proposed ACP and SHP facilities into service by the end of 2018. Where a potential for cumulative impacts was indicated, those impacts have been quantified to the extent practicable. In most cases, however, the potential impacts could only be described qualitatively (e.g., impacts from projects that are in planning stages or are contingent on economic conditions, availability of financing, or the issuance of permits). The criteria listed below define the Projects' region of influence, which is used in this cumulative impacts assessment to describe the general area for which the Projects could contribute to cumulative impacts. The region of influence varies depending on the resource being discussed. Potential impacts of the Projects on geology and soils, land uses, residential areas, visual resources, cultural resources, and traffic will be highly localized; therefore, other projects within 0.5 mile of the ACP and SHP work areas (e.g., commercial developments or transportation projects) were evaluated for cumulative impacts on these resources. Waterbody and wetland crossings, as well as potential impacts on groundwater, vegetation, and wildlife by the ACP and SHP will be localized. Therefore, the analysis included cumulative impacts on these resources from other projects within the same watersheds crossed by the Projects. Ongoing operation of the ACP and SHP compressor stations will result in continuing impacts on air quality in various Air Quality Control Regions (AQCRs). Therefore, other projects with the potential to result in continuing impacts on air quality (e.g., natural gas compressor stations or industrial facilities) within the AQCRs that will also be impacted by an ACP or SHP compressor station were considered. Continuing noise impacts from the ACP or SHP compressor stations will be localized to within 0.5 mile of each compressor station. Therefore, other projects that will result in continuing impacts on noise affecting the same noise -sensitive areas (NSAs) as the ACP and SHP compressor stations were evaluated. The anticipated cumulative impacts of the Projects and other actions are discussed below. 2.0 PROJECTS AND ACTIVITIES CONSIDERED Atlantic and DTI identified past, present, or reasonably foreseeable projects from review of topographic maps, internet research, and by contacting County and City officials regarding 10-5 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project recent or planned developments and significant commercial/industrial developments within the Counties and Cities crossed or affected by the Projects. Table A-1 in Attachment A lists past, present, and reasonably foreseeable future projects that may cumulatively or additively impact resources that could be affected by construction and operation of the ACP and/or SHP. s As noted in the following subsections, some projects were eliminated from further consideration if it was determined that they will not meet the criteria listed above or if insufficient information is available to allow for a meaningful analysis. Descriptions of potential cumulative impacts by resource category are presented in Section 3.0. In cases where quantitative information is not available for the projects considered in this analysis (e.g., projects in the planning stages or those contingent on economic conditions, availability of financing, or the issuance of permits), the potential impacts of those projects have been considered qualitatively. Other Known Federal Energy Regulatory Commission -Jurisdictional Projects In addition to the projects listed in Table A-1, there are FERC jurisdictional natural gas projects recently completed, currently proposed, recently approved, or under consideration in the States/Commonwealths crossed by the ACP and SHP, but not the same Counties or Cities. These include the Atlantic Sunrise Project in North Carolina, Pennsylvania, and Virginia; Constitution Pipeline and Wright Interconnect Projects in Pennsylvania; East Side Expansion Project in Pennsylvania; Marcellus to Manhattan Project in Pennsylvania; Niagara Expansion Project in Pennsylvania; Northeast Expansion Project in Pennsylvania; Northern Access 2015 — West Side Expansion Project in Pennsylvania; West to East Overbeck to Leidy Project in Pennsylvania; Giles County Project in Virginia and West Virginia; Kingsport Expansion Project in Virginia; Smithfield III Expansion Project in West Virginia; Uniontown to Gas City Expansion (U2GC) Project in Pennsylvania; and West Side Expansion and Modernization Project in Pennsylvania and West Virginia. None of these projects will occur within the same region of influence as the ACP and SHP; therefore, they are not discussed further. There are several FERC jurisdictional projects currently proposed, under consideration, being constructed, or recently completed that are located in whole or in part in the same Counties or Cities as some of the ACP and SHP facilities. These include the Mountain Valley Pipeline Project in Doddridge, Harrison, Lewis, Tyler, and Wetzel Counties, West Virginia (in pre -filing); Rover Pipeline Project in Tyler and Doddridge Counties, West Virginia (in pre -filing); Natrium to Market Project in Greene and Westmoreland Counties, Pennsylvania (completed in 2014); Texas Eastern Appalachia Market 2014 Project in Westmoreland County, Pennsylvania (construction ongoing), and Virginia Southside Expansion Project in Brunswick County, Virginia (construction ongoing). These projects are included in the cumulative impacts assessment (see Table A-1 in Attachment A). 5 Because the majority of potential project impacts will occur during the construction phase, the past projects included in Table A-1 primarily are recently completed projects (2014 or later). Projects completed prior to 2014 are considered part of the environmental baseline and are removed from further consideration unless operational impacts would affect the same resources as the ACP and SHP. 10-6 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project In addition to the FERC jurisdictional projects, DTI is proposing to add additional gas coolers at the existing Mockingbird Hill Compressor Station in Wetzel County, West Virginia as part of its proposed Monroe to Cornwell Project; and add a new turbine at the existing Burch Ridge Compressor Station in Marshall County, West Virginia as part of its Clarington Project. These Projects are not associated with the ACP or SHP. Construction activities for both Projects are expected to be confined to the existing station sites. Therefore, no cumulative impacts associated with these minor construction Projects are anticipated. 3.0 POTENTIAL CUMULATIVE IMPACTS BY RESOURCE 3.1 GEOLOGY AND SOILS The facilities associated with the Projects are expected to have a direct but temporary impact on near -surface geology and soils. Clearing activities could expose the soil to erosive elements such as precipitation and wind. Atlantic and DTI will minimize impacts on geological and soil resources by returning contours to preconstruction conditions to the maximum extent practicable and implementing the 2013 versions of the FERC's Upland Erosion Control, Revegetation, and Maintenance Plan (Plan) and Wetland and Waterbody Construction and Mitigation Procedures (Procedures) as well as appropriate State/Commonwealth requirements or guidelines. The effects on geology and soils will be highly localized and limited primarily to the period of construction; therefore, cumulative impacts on geology and soils will only occur if other projects are constructed at the same time and place as the proposed facilities. Although the Mountain Valley Pipeline Project has planned facilities in some of the same Counties as the ACP and SHP, and the construction schedule is very similar to that of the Projects (December 2016 through December 2018), the facilities are considered too distant to contribute to cumulative impacts on soils or geology. If the Mountain Valley Pipeline Project moves forward as currently planned, the impacts of that project on geology and soils will be similar to those of the ACP and SHP (i.e., short-term and localized impacts on topography and soils during construction). The Texas Eastern Appalachia to Market 2014, Natrium to Market, Virginia Southside Expansion, and Rover Pipeline Projects also have facilities located in the same Counties as the ACP or SHP. These projects are either completed or anticipated to be completed prior to construction of the ACP and SHP. Because impacts on topography and soils are short term and localized, and the rights-of-way and workspaces associated with construction of the Projects will be restored and stabilized prior to construction of the ACP and SHP, the potential for cumulative impacts is significantly reduced. No major long-term impacts are anticipated and, therefore, no significant cumulative impacts on geology and soils are expected. Construction of some of the other projects listed in Table A-1 in Attachment A could coincide with the schedule proposed for the ACP and SHP. Projects that require significant excavation or grading will also have temporary, direct impacts on near -surface geology and soils. Like the ACP and SHP, however, the duration and effect of these projects will be minimized by the implementation of erosion control and restoration measures. It is anticipated that project construction and restoration activities as well as operation and maintenance activities will be monitored throughout the process to verify compliance with erosion control and restoration 10-7 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project requirements. Consequently, potential cumulative effects on geological and soil resources are expected to be minor. 3.2 WATERBODIES, GROUNDWATER, AND WETLANDS Waterbodies Cumulative effects on surface water resources affected by the ACP and SHP will be limited to waterbodies that are affected by other projects located within the same watersheds. A total of 1,294 waterbodies will be crossed by the ACP, including 526 perennial streams, 542 intermittent streams, 151 ephemeral streams, 48 canals/ditches, and 27 open water ponds. A total of 145 waterbodies will be crossed by the SHP, including 119 perennial streams, 24 intermittent streams, and 2 open water pond. The ACP will cross 14 major waterbodies via the horizontal directional drill (HDD), dam-and-pump/flume, or wet crossing methods; the SHP will not cross major waterbodies. The Texas Eastern Appalachia to Market 2014, Natrium to Market, Virginia Southside Expansion, and Rover Pipeline Projects have facilities located in or near the same watersheds as the SHP; however, these projects are either completed or anticipated to be completed prior to construction of the ACP and SHP. Therefore, the potential for cumulative impacts is significantly reduced. Some of the other projects listed in Table A-1 will be located within the same watersheds crossed by the ACP and SHP, but only a small number of these will likely involve direct in -stream impacts. The ACP and SHP will not involve the construction of permanent diversions or dams. Therefore, the Projects are expected to have only temporary impacts on surface water quality. The greatest potential impacts of pipeline construction on surface waters will result from an increase in sediment loading to surface waters during construction and an increase in internal sediment loading due to channel/floodplain instability as a result of a change in erosion/deposition patterns. The level of impact will depend on precipitation events, sediment loads, stream area/velocity, channel integrity, bed material, and the proposed construction method. These impacts will be avoided or minimized by implementation of the measures in the Plan and Procedures as well as the construction, restoration, and mitigation plans that have been developed for the Projects, including a Spill Prevention, Control, and Countermeasures Plan (SPCC Plan) and Directional Drill Fluid Monitoring, Operations, and Contingency Plan (HDD Plan). The construction of some of the other projects listed in Table A-1 in Attachment A could coincide with the schedule proposed for the ACP and SHP. Like the ACP and SHP, projects that result in increased sediment loading will also have temporary, direct impacts on waterbodies. However, the duration and effect of these projects will be minimized by the implementation of erosion control and restoration measures. Consequently, potential cumulative effects on waterbodies are expected to be minor. Atlantic and DTI will hydrostatically test the new pipeline in accordance with the USDOT's Pipeline and Hazardous Materials Safety Administration's (PHMSA) pipeline safety regulations in 49 CFR 192 prior to placing the facilities into service. Water for hydrostatic BY., Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project testing will be withdrawn and discharged in accordance with State/Commonwealth regulations and required permits. The planned locations of withdrawals and discharges are identified in Resource Report 2. It is unknown at this time if the projects listed in Table A-1 will use water from the same surface sources within the same timeframe as the Projects. However, the proposed withdrawals and discharges for the ACP and SHP will be conducted in accordance with applicable State/Commonwealth permits and the Plan and Procedures (e.g., the test water will be discharged to well -vegetated upland areas). Therefore, long-term impacts on surface water sources are not expected as a result of hydrostatic testing activities, and the cumulative impacts on surface water resources associated with the ACP and SHP and the projects listed in Table A-1 are expected to be minor. Groundwater Cumulative effects on groundwater resources will be limited to areas that are affected by other projects located near the ACP and SHP facilities. ACP and SHP construction activities potentially could affect groundwater through increased turbidity, reduced water levels, and contamination from accidental spills and leaks of hazardous materials associated with construction equipment, refueling or maintenance of vehicles, and storage of fuel, oil, and other fluids. Upon completion of construction, Atlantic and DTI will restore the ground surface as closely as practicable to original contours and revegetate the rights-of-way to facilitate restoration of preconstruction overland flow and recharge patterns. Potential impacts on groundwater will be avoided or minimized by the use of both standard and specialized construction techniques, including those specified in the Plan and Procedures as well as implementation of the SPCC Plan. Portions of the ACP and SHP will be built in areas containing karst terrain. These areas have unique hydrology and highly productive aquifers which can be highly susceptible to contamination via sinkholes and other features which provide a direct connection to groundwater. Cumulative impacts on groundwater in karst areas are possible if construction of the projects listed in Table A-1 occur in areas with karst. Atlantic and DTI are conducting a survey to identify karst features along the route and will implement a Karst Monitoring and Mitigation Plan for the Projects. The plan identifies best management practices for erosion and sediment control, refueling, and other activities in the vicinity of karst features with a direct connection to groundwater. The plan also includes practices for monitoring construction and restoration activities in the vicinity of karst features. With the implementation of the Karst Monitoring and Mitigation Plan, no cumulative impacts on karst due to construction and operation of the Projects are anticipated. The new pipelines and aboveground facilities for the Projects are not expected to result in impacts on groundwater use or quality under typical operating conditions. Impacts could occur if maintenance activities require excavation or repair in proximity to water supply wells or springs. In such cases, the impacts and mitigation would be similar to those described above for construction activities. 10-9 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project Wetlands There will be a loss of some existing wetland features as a result of the construction and operation of the proposed ACP and SHP facilities and other reasonably foreseeable projects in West Virginia, Virginia, North Carolina, and Pennsylvania. Based on field and National Wetlands Inventory data, a total of 1,068 wetlands will be crossed by the proposed ACP pipelines and 24 wetlands will be crossed by the proposed SHP pipelines. Maintenance activities along the ACP and SHP pipeline rights-of-way will permanently affect approximately 204.7 acres of wetlands due to the conversion of palustrine forested wetland and palustrine scrub -shrub wetland to palustrine emergent wetland types. Additional wetlands will be affected by construction of aboveground facilities and use of access roads. Some of the projects listed in Table A-1 will be located within the same watersheds crossed by the ACP and SHP, but only a small number of these, if any, will likely involve direct impacts to the same wetland features. Atlantic and DTI will minimize impacts on wetlands by following the wetland construction and restoration guidelines contained in the Plan and Procedures; by implementing Compensatory Wetland Mitigation Plans; and by complying with the conditions of the wetland permits that will be issued by the U.S. Army Corps of Engineers (USACE) and State/Commonwealth agencies. Similar mitigation is expected to be required for wetland impacts associated with the other projects listed in Table A-1. Although construction of the ACP and SHP along with the other projects in the area could result in the conversion or reduction in the amount of existing wetlands in the vicinity, the creation of new wetlands and restoration or enhancement of existing wetlands as required by the USACE are expected to appropriately mitigate for impacts on wetland resources and minimize cumulative wetland effects. 3.3 VEGETATION, WILDLIFE AND HABITAT, AND AQUATIC RESOURCES Vegetation The Projects cross various upland and wetland land cover classes that support diverse vegetation communities. The proposed ACP pipeline facilities upland forest/woodland (241.8 miles), cultivated cropland (86.8 miles), wetlands (69.9 miles), pasture (64.2 miles), tree plantation/harvested forest (59.4 miles), developed (21.7 miles), open land (17.0 miles), and open water (3.3 miles). The proposed SHP pipeline facilities cross upland forest/woodland (33.0 miles), pasture (2.2 miles), developed land (1.3 miles), cultivated cropland (0.5 mile), wetlands (0.3 mile), open water (0.2 mile), open land (less than 0.1 mile), and tree plantations/harvested forest (less than 0.1 mile). The types of upland woodland/forest crossed by the Projects include coniferous forests, deciduous forests, mixed forests, deciduous savanna and glades, and floodplain and riparian forests. Right-of-way clearing and grading and other construction activities associated with the Projects along with some of the other projects listed in Table A-1 could result in the removal of vegetation, alteration of wildlife habitat, displacement of wildlife, and other potential secondary effects such as increased population stress, predation, and the establishment of invasive plant species. These effects would be greatest where the other projects are constructed within the same timeframe and areas as the ACP and SHP, and where the recovery time of the vegetation or habitat takes longer to restore to its preconstruction state. 10-10 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project Most areas disturbed by the Projects will be allowed to return to pre-existing conditions following construction. In addition, the extent and duration of impacts caused by construction of the ACP and SHP in these areas will be reduced by implementation of the Plan and Procedures, the SPCC Plan, and other construction, restoration, and mitigation plans. The other projects most likely will implement similar plans and procedures to avoid or minimize impacts. Most vegetation types affected by the Projects will be restored following construction. In forested areas, however, recovery of woody vegetation in temporary workspace could take decades. Additionally, forested land in the maintained pipeline rights-of-way will be converted to herbaceous cover types. If other projects built in the same areas as the ACP and SHP remove woody vegetation, cumulative impacts to forests could occur. As discussed previously, the Mountain Valley Pipeline Project will include pipeline facilities in some of the same Counties as the ACP and SHP and will be constructed on a similar schedule. For the shared Counties, the Mountain Valley Pipeline Project will likely result in vegetation impacts similar to the ACP and SHP. Although construction of the Texas Eastern Appalachia to Market 2014, Natrium to Market, Virginia Southside Expansion, and Rover Pipeline Projects are either completed or anticipated to be completed by the time the ACP and SHP are constructed, the effects of tree clearing and associated change in habitats will persist beyond restoration of the areas. Wildlife and Habitat Construction and operation of the Projects may result in short- and long-term impacts on wildlife species and their existing habitats along the proposed pipeline routes and at aboveground facility sites. The extent and duration of impacts will vary depending on the species present in each affected habitat type and their individual life histories. Construction activities will likely displace species from areas within and adjacent to the rights-of-way, but the impact is expected to be short term and limited to the period of construction. Operation of the proposed pipelines will cause minimal impacts on wildlife species because vegetation mowing or clearing will occur outside of the nesting season for migratory birds and no more than once every three years. Operation of the aboveground facilities may displace some species due to noise but there is ample suitable habitat available in the vicinity of the aboveground facility sites to accommodate these species. To minimize potential impacts on wildlife species, such as nesting and migratory birds and roosting bats, Atlantic and DTI will implement timing restrictions for vegetation clearing. After construction is complete, Atlantic and DTI will restore the rights-of-way as near as practicable to preconstruction conditions in accordance with the Plan and Procedures and the other construction, restoration, and mitigation plans prepared for the Projects. Cropland will be restored to active agricultural production, and other areas will be revegetated using methods and seed mixes appropriate to existing land uses and cover types. With the exception of forested lands, the Projects will not permanently alter the characteristics of the majority of the available wildlife habitats. Consequently, most impacts on wildlife are expected to be temporary. As discussed above, the Mountain Valley Pipeline Project will include pipeline facilities in some of the same Counties as the ACP and SHP and will be constructed on a similar schedule. 10-11 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project For the shared Counties, the Mountain Valley Pipeline Project will likely result in wildlife habitat impacts similar to the ACP and SHP. For the Texas Eastern Appalachia to Market 2014, Natrium to Market, Virginia Southside Expansion, Rover Pipeline Projects, and other projects listed in Table A-1 that are either completed or anticipated to be completed by the time the ACP and SHP are constructed, the effects of tree clearing and associated change in habitats will persist beyond restoration of the areas. Fish Construction of the ACP and SHP at the same time as other projects listed in Table A-1 could result in cumulative impacts on aquatic resources, such as groundwater, surface water, and wetlands. It is unclear how many of the streams crossed by the Projects could also be affected by other projects. Given that the Mountain Valley Pipeline will include pipeline facilities in some of the same Counties as the ACP and SHP, and will be constructed on a similar schedule, there is a potential for cumulative surface water and aquatic resource impacts. Potential impacts on waterbodies within the collective ACP/SHP and Mountain Valley Pipeline project areas could include temporary sedimentation and turbidity, destruction of stream cover, introduction of pollutants, interruption of fish migration and spawning, and entrainment of fish. Many of the potential impacts of the Projects on essential fish habitat (EFH) and managed fish species will be similar to those described for surface waters. Atlantic is evaluating the HDD method for the crossing of the Southern Branch Elizabeth River, which is designated as a Habitat Area of Particular Concern for the sandbar shark, serving as a primary and secondary nursery for this large coastal species. If implemented, the HDD method will avoid direct impacts on the waterbody. However, impacts on EFH could result from an inadvertent return of drilling fluid, inadvertent hazardous material spills, runoff of sediment from construction areas into the waterbody, or water withdrawals for hydrostatic testing. Most of the other waterbodies will be crossed using a dry crossing method, which will minimize impacts from sedimentation and turbidity. Based on the current schedule for the Projects, in -stream construction activities could take place year round. Nonetheless, Atlantic and DTI will comply with time of year restrictions and conditions unless specifically authorized by the appropriate agencies. To the extent that in - stream activities are necessary outside of construction timing windows for fish species, Atlantic and DTI will seek approvals from the appropriate agencies for these crossings on a case-by-case basis. Following construction, streambeds and banks will be restored to preconstruction contours to the extent practicable and stabilized. Disturbed areas will be seeded and mulched, as necessary, to prevent erosion. Permanent erosion and sediment controls will be installed as described in the Procedures. The potential impacts of the Projects on aquatic resources, including EFH, will be minimized through implementation of the measures described in the Procedures, SPCC Plan, HDD Plan, and other applicable mitigation measures. Operation of the ACP and SHP is not expected to affect fisheries. The Mountain Valley Pipeline Project is expected to implement similar plans and procedures. The potential for cumulative impacts will be minimized due to the short duration of the proposed in -stream activities and use of the HDD crossing method or dry crossing methods, 10-12 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project where applicable. Collectively, these measures will avoid significant cumulative impacts on aquatic resources, including EFH and managed fish species. If the other projects listed in Table A-1 involve direct in -stream impacts on waterbodies, they will be required to obtain permits from the USACE and appropriate State/Commonwealth agencies, and consult with the U.S. Fish and Wildlife Service (FWS) and other agencies as applicable. These agencies will assess the potential for cumulative impacts from these projects and require measures to mitigate impacts on aquatic resources associated with these other projects. Therefore, the cumulative effects on aquatic resources, including EFH and managed fish species, are expected to be minor. 3.4 LAND USE, RECREATION, SPECIAL INTEREST AREAS, AND VISUAL RESOURCES Land Use The ACP and SHP, in combination with other foreseeable future projects listed in Table A-1, will result in temporary and permanent changes in current land uses. Construction of the ACP will affect a total of approximately 9,829.9 acres, and construction of the SHP will affect a total of approximately 796.2 acres. For the ACP, upland forest/woodland is the principal land use type crossed at 241.8 miles or approximately 42.9 percent of the combined length of the proposed mainline and lateral pipelines. In descending order, the other land use types crossed by the ACP pipeline facilities are: cultivated cropland (86.8 miles or 15.4 percent), wetlands (69.9 miles or 12.4 percent), pasture (64.2 miles or 11.4 percent), tree plantation/harvested forest (59.4 miles or 10.5 percent), developed (21.7 miles or 3.8 percent), open land (17.0 miles or 3.0 percent), and open water (3.3 miles or 0.6 percent). The principal land use type crossed by the proposed SHP pipeline facilities is upland forest/woodland at 33.0 miles or approximately 88.0 percent of the combined length of the pipeline loops. In descending order, the other land uses crossed by the SHP facilities are pasture (2.2 miles or 5.9 percent), developed land (1.3 miles or 3.5 percent), cultivated cropland (0.5 mile or less than 1.3 percent), wetlands (0.3 mile or 0.8 percent), open water (0.2 mile of 0.5 percent), open land (0.1 mile or less that 0.1 percent), and tree plantations/harvested forest (less than 0.1 mile or less than 0.1 percent). The majority of land use impacts associated with the Projects will be temporary because most land uses will be allowed to revert to prior uses following construction, which will minimize cumulative impacts. An exception will be the conversion of forested land to herbaceous cover or developed land in the maintained easements for the pipelines and at aboveground facility sites. Recreation and Special Interest Areas Recreation and special interest areas include Federal, State/Commonwealth, or County parks and forests, conservation lands, wildlife habitat management areas, game management areas, natural landmarks, scenic byways, designated trails, recreational rivers, campgrounds, and cemeteries. The proposed ACP and SHP pipelines will cross or pass within 0.25 mile of a 10-13 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project number of publicly owned and managed lands, including lands managed by the U.S. Forest Service, National Park Service, FWS, State of West Virginia, and Commonwealth of Virginia. These lands include the Monongahela National Forest, George Washington National Forest, Appalachian National Scenic Trail (Appalachian Trail or Trail), Blue Ridge Parkway, Great Dismal Swamp National Wildlife Refuge, Huttonsville Wildlife Management Area, Lewis Wetzel Wildlife Management Area, and Highland Wildlife Management Area. For these areas, Atlantic and DTI will comply with the standards and guidelines of applicable land management plans and will implement the Plan and Procedures and other construction restoration and mitigation plans to avoid, minimize, or mitigate impacts. Addition discussion regarding the Appalachian Trail is provided in a separate subsection below. A number of other recreational or special interest areas will be affected by the ACP and SHP. Project impacts on these recreational and special interest areas occurring outside of forested land will be temporary and limited to the period of active construction. These impacts will be minimized by implementing the Plan and Procedures, the SPCC Plan, and other applicable mitigation measures. Some of the other projects listed in Table A-1 have crossed or will cross Federal, State/Commonwealth, or local recreation and special interest areas. However, none appear to cross at the same locations as those affected by the ACP and SHP. As a result, although the Projects could have impacts on recreation and special interest areas, cumulative impacts on those same areas are not anticipated. Appalachian Trail Atlantic is aware of several other pipeline projects under development that are proposing to cross the Appalachian Trail at various points along its approximately 2,180 -mile -long distance. Table 3.4-1 identifies projects where public information is available indicating that the projects are actively under development as of the date of this filing. After reviewing available information, Atlantic has omitted from this table projects for which development has been suspended or on hold (e.g., Spectra Energy's Carolina Pipeline Project and Transcontinental Gas Pipeline Company's Appalachian Connector Project). Atlantic is not involved with the development of other pipeline projects that may cross the Appalachian Trail. The purpose of the ACP is to provide new natural gas infrastructure at delivery points to serve consumers in southeastern Virginia and eastern North Carolina. No other project shares the same delivery points or meets the same demand for natural gas service at these locations. If constructed, the Mountain Valley Pipeline, as currently proposed, will cross the Appalachian Trail over 110 miles to the southwest of the proposed ACP crossing of the Trail. This is the closest known potential pipeline crossing of the Appalachian Trail to the ACP. The distance between the ACP and the Mountain Valley Pipeline will avoid potential cumulative impacts by separating the areas of effect. Other proposed pipeline projects crossing the Appalachian Trail are at even greater distances away from the ACP creating even less cumulative effects should these projects ever be constructed. 10-14 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project TABLE 3.4-1 Other Projects Proposing to Cross the Appalachian Trail Distance and Direction from Location of the Proposed Existing Facilities Proposed the ACP crossing of the Applicant Project Description Appalachian Trail Crossing at Crossing Crossing Method Status Appalachian Trail Tennessee Gas Northeast 30 -inch diameter Berkshire County, MA, Adjacent to an Conventional FERC pre -filing; Approximately 480 miles to Pipeline Energy Direct natural gas transmission approximately 1 mile east of existing electric bore construction the northeast pipeline Pittsfield transmission line anticipated in 2017 UGI Penn Unknown 16 -inch diameter Berks/Schuylkill County line, Greenfield Unknown Unknown Approximately 230 miles to natural gas transmission PA, approximately 5 miles the northeast pipeline northwest of Bethel Transcontinental Atlantic Sunrise 42 -inch diameter Lebanon County, PA, Greenfield Conventional FERC Approximately 230 miles to Gas Pipeline natural gas transmission approximately 4 miles bore proceeding; the northeast pipeline north/northeast of Ft construction Indiantown Gap anticipated in 2016 Mountain Valley Mountain Valley 42 -inch diameter Monroe County, WV/Giles Greenfield Undetermined FERC pre -filing; Approximately 100 miles to Pipeline Pipeline natural gas transmission County, VA line, construction the southwest pipeline approximately 4 miles north of anticipated in Pearisburg 2017 PermEast PennEast 36 -inch diameter Carbon County, PA, Greenfield Conventional FERC pre -filing; Approximately 270 miles to Pipeline Pipeline natural gas transmission approximately 0.5 mile north bore construction the northeast Company pipeline of Danielsville anticipated in 2017 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project By utilizing the trenchless HDD method to install the proposed pipeline beneath the Appalachian Trail (and adjacent Blue Ridge Parkway and portions of the George Washington National Forest), direct impacts to the Trail will be minimized, including impacts on vegetation immediately adjacent to the Trail. The proposed entry and exit locations for the HDD will be located approximately 1,385 feet to the northwest and 3,375 feet to the southeast of the AT, respectively. These distances from the Appalachian Trail will represent areas where no clearing of trees along the right-of-way will occur on the land surface in the immediate vicinity of the Trail, significantly minimizing the potential for visual impacts to users of the Trail. Short-term impacts on visitors to the Appalachian Trail and Blue Ridge Parkway could result from construction noise associated with the HDD, but these impacts will be temporary, localized, and limited to the period of construction. Atlantic will implement mitigation measures during the HDD to minimize noise, if necessary. In May of 2015, the Appalachian Trail Conservancy (ATC) finalized its Policy on Pipeline Crossings of the Appalachian Trail (ATC, 2015). This policy document states that the ATC will participate and encourage Appalachian Trail -maintaining clubs, individual members, agency partners, and natural resource conservation organizations to participate in public review procedures for all pipelines proposed to cross the Appalachian Trail landscape. The ATC Policy sets out criteria the ATC will utilize to consider new pipeline proposals. As noted on its website, the ATC "seeks to avoid, minimize, or eliminate the visual and experiential impacts of all utilities, including oil, gas, and petroleum products pipelines, on the Appalachian Trail and its surrounding landscapes. Where it is not possible to eliminate impacts, the ATC's goal is to obtain mitigation or offsets that result in no net loss of Trail values." As outlined in Resource Report 1, Atlantic is consulting with the ATC on the Project to minimize its impacts to the Appalachian Trail and its visitors. For these reasons, cumulative impacts to the Appalachian Trail system due to construction and operation of the ACP are not anticipated. Visual Resources The proposed ACP and SHP cross a range of visual landscapes, from mountainous areas to mosaics of forest and farmland to suburban and urban settings. Visual resources in these areas are a function of geology, climate, and historical processes as influenced by topographic relief, vegetation, water, wildlife, and land use (e.g., industrial, timber, agriculture, and urban development activities). The visual qualities of the landscape are further influenced by existing linear installations such as highways, railroads, pipelines, and electrical transmission and distribution lines. The physiographic provinces crossed by the ACP and SHP include the Appalachian Plateau Province, Valley and Ridge Province, Blue Ridge Province, Piedmont Province, and Coastal Plain Province. Visual impacts will be greatest where the pipeline route parallels or crosses roads and the pipeline right-of-way may be seen by passing motorists, at residences where vegetation used for visual screening or for ornamental value is removed, in forested areas, and in mountainous areas. The duration of visual impacts will depend on the type of vegetation that is cleared or altered. The impact will be greater in forested land, which will take longer than other vegetation types to 10-16 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project regenerate and will be prevented from re-establishing on the permanently maintained rights-of- way. Topographic alterations such as side -hill cuts that may be necessary to construct the pipeline will be restored during right-of-way restoration. The visibility of such alterations will diminish over time as the affected areas age and begin to blend with the surrounding landscape. To minimize construction impacts on visual resources, Atlantic and DTI have aligned the proposed pipeline routes adjacent to existing utility transmission rights-of-way or other transportation corridors where feasible. In areas where right-of-way collocation is not feasible, Atlantic and DTI have aligned the pipeline to avoid aesthetic features to the extent practicable, and will restore the right-of-way in accordance with the Plan and Procedures and the other construction, restoration, and mitigation plans prepared for the Projects. In many cases, aboveground facilities will be constructed on the same sites (e.g., the Kincheloe M&R Station will be built on the same site as Compressor Station 1), at existing aboveground facility sites, or along existing pipeline facilities, which will minimize visual impacts. Upon completion of construction, all of the aboveground facility sites will be stabilized with gravel within a fenced enclosure for security. Lighting and signage will be designed to minimize impacts on adjacent residences and sensitive resources. Atlantic and DTI will consult with local jurisdictions regarding appropriate landscaping and/or other means of mitigating visual impacts of these facilities. For public lands and aboveground historic properties affected by the Projects, Atlantic and DTI will mitigate for effects on visual resources in accordance with the requirements of the visual resource management system specific to the applicable agency. Of the projects listed in Table A-1, the proposed linear projects are likely to have the greatest cumulative impact on visual resources. The ACP and SHP facilities will add incrementally to this impact but the overall contribution will be relatively minor given that the majority of the ACP and SHP pipeline facilities will be buried. For aboveground facilities, the impacts on visual resources from each individual facility will depend on the preconstruction condition and the visibility from the surrounding area. As discussed above, the impact of the aboveground facilities on visual resources will be minimized by constructing them on the same site or at or along existing sites/facilities in many cases. Disturbed areas will be revegetated after construction, and mitigation measures will be implemented to minimize visual impacts to the extent practicable. Projects listed in Table A-1 may also be required to evaluate potential visual impacts and implement appropriate mitigation measures as required by land management agencies and applicable regulations. Therefore, cumulative visual impacts will be reduced. 3.5 SOCIOECONOMICS Economy and Employment Atlantic and DTI estimate that approximately 50 percent of the ACP and SHP workforces will be individuals who reside within commuting distances of the Projects or are members of a local union hall. The Counties and Cities affected by the Projects have a combined civilian labor force of approximately 950,347 people and an average unemployment rate of 6.7 percent (U.S. Census Bureau, 2015). These data suggest that the local labor force could meet much of 10-17 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project the employment needs required for construction of the Projects. However, if other projects are built at the same time, the demand for workers could exceed the local supply of appropriately skilled labor. If the Mountain Valley Pipeline Project moves forward as planned, the construction schedule will be similar to the Projects, which could impact the supply of available local workers. Should the portions of the projects, or portions of the other projects in Table A-1 that are in the same or surrounding Counties, be constructed at the same time as the Projects, skilled labor from the adjacent non -shared Counties could potentially be employed. Because the Texas Eastern Appalachia to Market 2014, Natrium to Market, Virginia Southside Expansion, and Rover Pipeline Projects are completed or anticipated to be completed prior to construction of the ACP and SHP, no cumulative impacts are likely from these projects. Atlantic and DTI will hire an estimated 92 permanent employees to support operation and maintenance of the ACP and SHP facilities, and it is likely that new permanent employees will be hired for some the other projects. The hiring of these workers will have a minor but positive impact on unemployment in the Counties crossed or affected by the Projects. The long-term employment opportunities associated with the other projects in Table A-1 are unknown, but they are likely to provide some other permanent employment opportunities. In addition to a positive impact on local employment, all of the projects will provide an increase in tax revenue for Pennsylvania, West Virginia, Virginia, and North Carolina and a positive impact on local economies through the payment of payroll, sales, and property taxes and other taxes and fees. Construction and operation of the ACP will result in economic benefits through increased payroll, tax revenue, purchase of materials, and utilization of local vendors and businesses. Atlantic and DTI commissioned a study by Chmura Economics and Analytics (Chmura) to assess the economic impact of construction and operation of the ACP (Chmura, 2014). Assuming that capital expenditures associated with construction of the ACP will total $4.6 billion dollars, 6 the study found a total economic impact (direct, indirect, and induced) of $2.7 billion supporting a total of 17,240 jobs in West Virginia, Virginia, and North Carolina. During operation, the ACP will have an annual direct spending impact of $69.2 million in 2019 dollars and employ 82 permanent workers in the three-State/Commonwealth region (22 in West Virginia, 39 in Virginia, and 20 in North Carolina). Additionally, operation of the ACP will have an indirect annual impact of $15.3 million in spending supporting 99 jobs (including operational support positions with other regional companies, such as equipment maintenance and repair personnel), and an induced annual impact of $12.6 million in spending supporting 90 jobs. The annual induced impact will mostly support consumer service industries (Chmura, 2014). Cumulatively, the Projects and the other nearby projects will have both short- and long- term beneficial impacts on State/Commonwealth, County, City, and local economies. At a County/City or local level, these beneficial impacts are anticipated wherever one or more projects occur in the same County or City. Table A-1 includes a column which identifies common Counties and Cities between the ACP, SHP, and other projects. At least one past, 6 The $4.6 billion capex is at the lower end of the range of $4.5 to $5 billion to construct the ACP. 10-18 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project present or reasonably foreseeable project occurs in each of the Counties and Cities crossed or affected by the ACP and SHP, with the exception of Nottoway County, Virginia, where there are none. Temporary Housing Temporary housing will be required for construction workers who will be needed for the portion of the workforce not drawn from the local area. Given the current vacancy rates, the number of rental housing units in the area, and the number of hotel/motel rooms available in the cities and towns in the vicinity of the Projects, construction workers should not encounter difficulty in finding temporary housing. If construction of the ACP and SHP occurs concurrently with other projects, temporary housing may be more difficult to find and/or more expensive to secure due to increased demand among workers. Some workers could be displaced to adjacent Counties or Cities, which could increase commute times for these workers. These effects will be temporary, lasting only for the duration of construction. There will be no long-term cumulative impact on housing from the proposed Projects. Public Services The cumulative impact of the ACP and SHP and the other projects listed in Table A-1 on infrastructure and public services will depend on the number of projects under construction at one time. The small incremental demands of several projects occurring at the same time could increase the need for police, fire, and emergency services. The increased need will be temporary, occurring only for the duration of construction, and could be mitigated by the various project sponsors providing their own personnel to augment the local capability or by providing additional funds or training for local personnel. These activities would avoid or minimize the potential for cumulative impacts. As discussed in Resource Report 5, Atlantic and DTI will work with police, fire, and medical services in the affected Counties and Cities to coordinate activities and confirm that adequate resources are available for effective emergency response. The construction team leaders (representing the construction contractors, DTI construction managers, DTI Project supervisors, and DTI Project managers) will meet with emergency responders in each County/City along the proposed pipeline routes to develop a response plan tailored to the capabilities or needs of each County/City. These actions will help ensure adequate resources to minimize cumulative impacts on emergency responders. No long-term impacts from implementation of the ACP and SHP on infrastructure and public services are anticipated. Therefore, no long-term cumulative effects are likely to occur. Traffic and Transportation Construction of the ACP and SHP could have a temporary impact on road traffic in some areas and could contribute to cumulative traffic, parking, and transit impacts if other projects are scheduled to take place at the same time and in the same area as the Projects. 10-19 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project Construction of the Projects will result in minor, short-term impacts on transportation networks due to construction across roads and highways, commuting of the workforce, and the movement of vehicles and delivery of equipment and materials to work areas. In addition, the movement of construction equipment, materials, and personnel will cause a slight, temporary increase in traffic volumes along area roadways. Impacts are expected to be minor and short term because construction spreads and personnel will be geographically dispersed and personnel will commute to and from work areas in early morning and late evening during non -peak traffic hours. Additionally, Atlantic and DTI have developed and will implement a Traffic and Transportation Management Plan, which will identify measures to minimize impacts on roadways and traffic during construction. Once construction is complete, Atlantic's and DTI's construction contractors will repair road damage that occurs as a result of construction, and roadways will be restored to their preconstruction condition. It is anticipated that other projects that may be constructed at the same time in the ACP Project area or SHP Project area will be expected to implement similar transportation and traffic control mitigation measures as described above. With the implementation of these measures, no significant cumulative traffic impacts are anticipated during construction of the Projects. Summary Overall, the ACP and SHP will have short-term but positive effects on the economy in the ACP Project area and SHP Project area, such as increased employment and sales and tax revenues. Other major projects in the area will likely have similar impacts on the economy. Thus, cumulative positive effects on socioeconomics in the ACP Project area and SHP Project area are likely. 3.6 CULTURAL RESOURCES As discussed in Resource Report 4, Atlantic and DTI have/are conducting field surveys to identify archaeological and other historic sites that may be impacted by the Projects. The sites will be evaluated to determine their eligibility for listing in the National Register of Historic Places (NRHP). Atlantic and DTI intend, to the extent practicable, to avoid impacts on cultural resource sites that are listed on or eligible for listing on the NRNP. A number of route variations and adjustments to date have been identified, evaluated, and incorporated into the proposed routes to avoid impacts on listed, eligible, or potentially eligible properties. In the event that listed or eligible sites cannot be avoided, Atlantic and DTI will prepare treatment plans for these sites in consultation with FERC staff; the appropriate Federal, Tribal, and State/Commonwealth agencies; and applicable stakeholders. Additionally, Atlantic and DTI have developed and will implement a Plan for the Unanticipated Discovery of Cultural Resources or Human Remains during Construction for each State/Commonwealth to address unanticipated finds of artifacts or human remains during construction of the Projects. All these actions collectively will avoid, minimize, or mitigate impacts on significant cultural resource sites. The currently proposed projects listed in Table A-1 which are Federal actions will include measures (like the Projects) for avoiding, minimizing, or mitigating impacts on listed, eligible, or potentially eligible properties. Where direct impacts on significant cultural resources are unavoidable, mitigation (e.g., recovery and curation of artifacts) will occur before 10-20 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project construction. Non -Federal actions will need to comply with mitigation measures required by the historical preservation office in the affected State/Commonwealth. For these reasons, and because impacts tend to be highly localized, cumulative impacts on cultural resource sites are not anticipated or will not be significant. 3.7 AIR QUALITY AND NOISE Air Quality Construction Emissions Construction of most of the reasonably foreseeable future projects and activities listed in Table A-1 will involve the use of heavy equipment that will generate emissions of air pollutants, including fugitive dust. Consequently, construction of the ACP and SHP will contribute cumulatively to air quality impacts. The combined impact of multiple construction projects occurring in the same air shed and timeframe as the Projects could temporarily cause cumulative air impacts in the ACP Project area and SHP Project area. Construction activities for the proposed ACP and SHP facilities will result in emissions of some pollutants due to the use of non -stationary equipment powered by diesel fuel or gasoline engines; the temporary generation of fugitive dust due to disturbance of the ground surface and other dust -generating actions; and indirect emissions attributable to workers commuting to and from work sites during construction. These emissions will be temporary and localized and are not expected to cause or significantly contribute to an exceedance of the National Ambient Air Quality Standards (NAAQS). Construction of many of the projects listed in Table A-1 either will not occur at the same time as construction of the ACP and SHP facilities or they are located sufficiently far away as to not result in cumulative air impacts due to construction. Operations Emissions The proposed ACP compressor stations are all located in Counties designated as being in attainment with the NAAQS for all criteria pollutants (i.e., sulfur dioxide, carbon monoxide, nitrogen dioxide, inhalable particulate matter [both particulate matter sized 10 microns and smaller in diameter and sized 2.5 microns and smaller in diameter], lead, and ozone). Therefore, the stations must be evaluated to determine applicability of the Clean Air Act preconstruction permitting program for attainment areas — the Prevention of Significant Deterioration (PSD) program. Because the estimated potential compressor station emissions are not expected to exceed the threshold value of 250 tons per year for criteria air pollutants, construction and operation of the proposed ACP compressor stations will not trigger PSD requirements. Moreover, none of the compressor stations are expected to emit more than 100,000 tons per year of greenhouse gases (GHG). The proposed modifications to the SHP compressor stations in West Virginia will occur in Counties designated as being in attainment with the NAAQS for all criteria pollutants. Because the Commonwealth of Pennsylvania is part of the Ozone Transport Region, all Counties in Pennsylvania are treated as non -attainment for ozone. However, the estimated potential emissions associated with the proposed work at the JB Tonkin and Crayne Compressor Stations will not exceed applicable Non -attainment New Source Review permitting 10-21 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project thresholds. Further, the modifications to the Crayne and JB Tonkin compressor stations do not trigger PSD for non -ozone precursor pollutants either. However, the modifications to the Mockingbird station trigger the PSD major modification thresholds for particulate matter and GHG emissions. Recent projects performed at the existing compressor stations do not change this analysis. In 2014, DTI completed construction of the Natrium to Market Project in Greene and Westmoreland Counties, Pennsylvania. This project included the construction and operation of a new 7,700 -horsepower compressor unit, upgrades to an existing measurement and regulation station at the Crayne Compressor Station in Greene County, and changes to the JB Tonkin Compressor Station in Westmoreland County. Although DTI will perform additional work at the Crayne and JB Tonkin Compressor Stations for the SHP, the potential cumulative increase in emissions at these compressor station sites will be minor and is not anticipated to trigger PSD permitting, even considering the previous work at these facilities. In addition to the new and modified compressor stations, the proposed new M&R stations for the ACP will be sources of air emissions during operations. Additionally, non -combustion related emissions will occur from the pipeline and at the proposed M&R stations during normal operations. The potential emissions associated with the operation of the other projects in Table A-1 are unknown, but because the projects listed in the table are located over a large area, have varying construction schedules, and must adhere to Federal, State/Commonwealth, and local regulations for the protection of ambient air quality, significant cumulative impacts on air quality are not anticipated. Greenhouse Gas Emissions On December 18, 2014, the Council on Environmental Quality (CEQ) issued a draft guidance document designed to assist federal agencies in the review of greenhouse gas (GHGs) emissions under NEPA. The document — Draft Guidance for Greenhouse Gas Emissions and Climate Change Impacts ("Draft Guidance") — was released for public comment and consideration and, to date, CEQ has not indicated how it will respond to the significant comments it received. As guidance, this document is subject to revision, modification, or even withdrawal, and is not a final product of CEQ. Nevertheless, the following is noted with respect to the draft CEQ guidance. The ACP and SHP will have de minimis direct emissions of GHGs resulting from temporary construction equipment, the operation of compressor stations, and occasional minor methane leaks from pipeline operations. Total direct GHG emissions from these ACP and SHP sources are projected by source in Resource Report 9. Currently, there is no standard methodology to determine how a project's relatively small incremental contribution to GHGs would result in physical effects on the global environment. Nonetheless, while comparing the Project's emissions to emissions across the region is not determinative of potential impacts, such a comparison is helpful in putting the emissions into context. The annual increase in future potential GHG emissions for the Projects is negligible in comparison to the reported GHG emissions for the States/Commonwealths encompassing the project area (e.g., West Virginia, Virginia, and North Carolina). While the potential GHG emissions associated with the operation of the other projects in Table A-1 are unknown, the emissions from the Project would not 10-22 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project produce significant incremental impacts in the Project area. Moreover, by increasing the availability of natural gas for electricity generation, it is expected that the Project will facilitate long-term reductions of GHG emissions in the Project area. Noise The Projects could contribute to cumulative noise impacts. In general, the operation of the new and modified compressor stations and proposed new M&R stations for the Projects will result in an increase in noise levels in the vicinity of the respective stations over the life of the facilities. In addition, the installation of the new pipelines and other related construction activities, including HDD crossings, will result in short-term increases in noise in the vicinity of those activities. As needed, Atlantic and DTI will incorporate noise control measures and equipment sound specifications into facility design plans to minimize noise impacts. Noise impacts during construction will be highly localized and attenuate quickly as the distance from the noise source increases. Noise studies were completed to assess possible operational noise impacts at the ACP and SHP aboveground facilities. For the analysis, the sound contribution of each station, as well as the total noise (i.e., estimated sound level contribution of the station plus the measured ambient noise level) was estimated at the closest NSA. The results of the acoustical analysis for the compressor stations and M&R stations indicate that, with the implementation of adequate noise control measures, the estimated noise attributable to the operation of the compressor or M&R stations will be lower than 55-dBA L& or would be consistent with the existing noise environment. Because noise sources that could cause perceptible vibration will be adequately mitigated, no perceptible increase in vibration at NSAs during operation of the new compressor stations is anticipated. Noise associated with a blowdown event during operations will be controlled to minimize impacts on nearby NSAs. The noise level of a unit blowdown event via a blowdown silencer will be specified to meet a sound level of 60 dBA at a distance of 50 feet to control noise levels at the closest NSA. Long-term cumulative noise impacts are possible in the areas surrounding the ACP and SHP compressor stations if other noise -generating facilities are constructed in close proximity to the ACP and SHP compressor stations. As discussed above, DTI completed construction of the Natrium to Market Project in Greene and Westmoreland Counties, Pennsylvania, which included the construction and operation of a new 7,700 -horsepower compressor unit, upgrades to an existing M&R station at the Crayne Compressor Station in Greene County, and modifications to the JB Tonkin Compressor Station in Westmoreland County. Although DTI will also perform modifications to the Crayne and JB Tonkin Compressor Stations for the SHP, the cumulative potential increase in noise at the compressor station sites is anticipated to be relatively minor. Therefore, significant noise impacts associated with construction and operation of the ACP or SHP are not anticipated. 3.8 RELIABILITY AND SAFETY Potential impacts of the ACP and SHP on public safety will be mitigated through implementation of PHMSA's Minimum Federal Safety Standards in 49 CFR 192, which are 10-23 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project designed to protect the public and prevent natural gas facility accidents and failures. Atlantic and DTI will design, construct, operate, and maintain the pipeline, aboveground, and other associated facilities in accordance with the regulations in 49 CFR 192 and other applicable laws and regulations. In addition, Atlantic and DTI will implement the mitigation measures specified in all safety plans and procedures (see Resource Report 11). Other projects potentially constructed in the vicinity of the ACP and SHP will be required to adhere to the safety requirements, procedures, and laws and regulations applicable to those projects. Therefore, no cumulative reliability or safety impacts are anticipated. 4.0 CONCLUSION Past, present, and reasonably foreseeable future projects in the ACP Project area and SHP Project area were identified for inclusion in this cumulative impacts assessment (see Table A-1 in Attachment A). The majority of the potential impacts associated with the Projects will be temporary and minor when considered in combination with other past, present, and reasonably foreseeable activities. However, some long-term cumulative impacts will occur on wetlands and forested lands and associated wildlife habitats. Some long-term cumulative socioeconomic benefits to the communities in the ACP Project area and SHP Project area will be realized from increased spending and tax revenues. Short-term cumulative benefits will also be realized through increased jobs and wages and purchases of goods and materials. In summary, due to the implementation of specialized construction techniques, the relatively short construction timeframe in any one location, and carefully developed resource protection and mitigation plans, minimal cumulative effects are anticipated when the impacts of the ACP and SHP are added to the projects identified in Table A-1. 10-24 Cumulative Impacts Assessment for the Atlantic Coast Pipeline and Supply Header Project 5.0 REFERENCES Appalachian Trail Conservancy. 2015.

Projects completed prior to 2014 are considered part of the environmental baseline and are removed from further consideration unless operational impacts would affect the same resources as the Atlantic Coast Pipeline or Supply Header Project. b This table lists those projects that are most likely to contribute to the cumulative impacts within the vicinity of the proposed Atlantic Coast Pipeline and Supply Header Project; it is not intended to provide an all-inclusive listing of projects in the region. This is a nonjurisdictional facility associated with the Atlantic Coast Pipeline or Supply Header Project. d This project has no facilities located in a common County or City with either the Atlantic Coast Pipeline or Supply Header Project. These projects are included in Table A-1 in response to an agency request. 10-A-12
