The permanent easement will be 50 feet wide for the 36 inch pipe, however in wetlands only a 10-foot corridor centered on the pipeline will be maintained in herbaceous vegetation, and 15 feet on either side (30 feet total) of the pipeline will be maintained clear of trees to minimize tree root encroachment on the pipeline. The 1O foot herbaceous corridor will be included within the 3O foot wide treeless corridor, this will not be additive to 40 feet as your meeting notes indicate. In addition, I have a point of clarification regarding this paragraph in your notes: " Bailey expressed concerns (from past experience) about hao+outs, and the possibility that pipeline may need to go deeper than the proposed 4'5'depth through wetlands. Bailey stated that on the pipeline he worked with they went 40' in wetlands and were able to avoid frac-ouis.NRG discussed limitations in pipe flexibi|ity." | wanted io comment that the 4O foot depth mentioned was specific to use of the horizontal directional drill method, and thus the comment regarding frac-outs. The pipeline would typically be buried with 3 feet ofcover. In agricultural land there would typically be 4 feet of cover, and typically 4-5 feet atwaterbodycrossings. With standard construction methods the pipe would typically be buried 3feet in wetlands unless there was an adjacent waterbody that would necessitate a deeper trench. The deeper trench at waterbodies is to account for active channel erosion. I hope this clarification is helpful. Please let me know if you have any questions regarding the clarifications. Thank you for taking time to compile the notes.

ES| and Pilot Consulting doing JD work; which b well underway, and nearly complete insome counties; probably ready for verification late fall nr winter in most counties Website for information: dom.com/acpipeline Counties maps can be found on this website by going to "Additional Details" at bottom of home page and choosing "Proposed Routes" David Shaeffer will work with NRG to uploads county maps to Simsuite Will apply for 404 & 401 August or September of next year- 2015 (before completion of FERC EIS); July 2016 expected FERC order authorizing project; construction to begin late 2016 or early 2017; website says construction in 2017 & 2018, with pipeline operational late 2018. Discussion on whether an|PurNVVP12 can be used for project; decision dependanton impacts and (somevvhat) what other districts are using. Final decision likely at the District level. Discussion of NWP expiring in March of 2017 and one year extension for work underway. If construction not completed by this period, permit will need to be re-issued. There is a possibility that terms and conditions of NWP can change for reissued permit. Bailey expressed concerns (from past experience) about frac-outs, and the possibility that pipeline may need to go deeper than the proposed 4-5' depth through wetlands. Bailey stated that on the pipeline he worked with they went 40' in wetlands and were able to avoid frac-outs. NRG discussed limitations in pipe flexibility. Shaeffer discussed alternative analysis requirements - especially for an IP Discussion on directional boring required per Regional Conditions of NWP12 whenever practicable; need to justify why directional boring was not used Questions concerning FO|; especially during early stages of planning. USACE needs to consult with USACE legal Burclette discussed buffers and pipeline running perpendicular to buffers (mitigation may be required if the pipeline crosses or runs perpendicular tobuffers) Brief discussion on how clearing in wetlands will be handled - need for clarification from NRG on this point. NRG will coordinate with USACEtn provide impactinfonnationinexce|spneadxheet format for easy download into USACE data base. Spreadsheet is attached to this email. To be determined whether Burclette will accompany USACE on verifications; Brown requested that consultants that did JD be present during verification. Each Regulator will be responsible for verification in her/his county. There is a small percentage of landowners in NC that have not allowed access to their property. Corps will not be able to verify nnthese properties, but may be able to do desktop JD. NRG/Dnminionto provide USACEo copy of release that landowners sign to allow for determinations on their property. USACE emphasized the need for owner permission in order to access property.
