Response to NCDE,Q Reguest for Additional Information dated September 14, 2017: The North Carolina Department of Envirom-nental Quality (NCDEQ). Division of Water Resources (Division), sent a "Request for Additional Information" to Atlantic Coast Pipeline, LLC (Atlantic), dated September 14, 2017, to address public comments from a public comment period held by the Division between June 16 and August 19, 2017, and to address public comments from public hearings held on July 18 and 20, 2017. Consistent with a previous request for information submitted to Atlantic dated June 28, 2017, the Division stated that Atlantic's response to the September 14 request was necessary to process Atlantic's application requesting an Individual Water Quality Certification/Buffer Authorization for the Atlantic Coast Pipeline Project (ACP or Project). Atlantic has reviewed the NCDEQ request for additional information and is providing the following responses and attached information according to the NCDEQ request. This is part 2 of Atlantic's submittal. Previously submitted items are noted in the responses below. Each of the requests for information, as numbered in the NCD�EQ request, is provided below, followed by Atlantic's response in italics: I . The proJect invokes IlUmerous stream crossings that have the potential to affect downstream water quality both temporarily during construction and permanently. YOUr application and responses to the Division provide thorough general descriptions of the plans for the proJect, however more site-specific detail is necessary to ensure that do�,\nstrearn water qualiaN is protected. Provide the additional,justification requested below: a.

The anticipated cumulative impacts of the Project and other actions 04 are discussed below. 00 STUDY AREA BOUNDARIES 00 Atlantic analyzed cumulative impacts on resources found within the construction _Lq�nnt�sf the three M&R stations proposed in North Carolina. Other projects within three counties were analyzed to determine if potential cumulative impacts on these resources would 9 0 occur, The proposed Smithfield M&R station is an approximately 5.5 acre site located in 00 Johnston County- The proposed Fayetteville M&R station is located in Cumberland County and encompasses approximately 6.75 acres. The proposed Pembroke M&R station contains 00 approximately 2.5 acres and is located in Robeson County. 00, Smithfield M&R station is located in central Johnston County, in a rural setting OR approximately 2.5 miles west from the town of Smithfield. According to the U.S. Census Bureau, Johnston County had an estimated population increase of 13.3% from 20 10 until early 00 2016,. Johnston County has experienced a steady, long-term increase in economic activity. This is attributed to the Research Triangle associated with Raleigh and Wake County. Recently, the county has seen a transformation of a primarily agrarian land use to a mix of urban, agricultural, and forested landscapes. According to the County Comprehensive Plan, Johnston County has had significantly high growth rates since 1990, a trend expected to continue (Johnston County, 2009). The closest population center to the Smithfield M&R station is the town of Smithfield. 00 According to the town's website, Smithfield is considered a small, historic town with growing business opportunities. The Fayetteville M&R site is located in northern Cumberland County. The proposed site is approximately 10 mdes north of the city of Fayetteville and 1.5 miles west from the town of Wade. The area inimediately surrounding the site is rural and contains agricultural fields. In OR 2009, Cumberland County adopted a 2030 Growth Vision Plan and a Land Use Policies Plan that describes growth in the economy and development while maintaining a desire to preserve open space and rural character (Cumberland County, 2009). The Pembroke M&R Station is located in Robeson County, North Carolina, According to Robeson County's Comprehensive Plan with a Health and Wellness Component, population is expected to increase approximately 20% by the year 2030 in surrounding counties. The town of Pembroke, North Carolina is approximately 3 miles north of the Pembroke M&R Station. The town experienced a 10.9% increase in growth from the year 2000-2010. Robeson County has also seen an increase of housing of 10.3% between 2000 and 20 10 (Robeson County, 20 14).
