US Army Corps of Engineers Omaha District ENVIRONMENTAL ASSESSMENT ADDENDUM & MITIGATED FINDING OF NO SIGNIFICANT IMPACT SACAGAWEA PIPELINE MCKENZIE AND MOUNTRAIL COUNTIES, NORTH DAKOTA April 2016 Prepared for: Paradigm Midstream Services – ND, LLC Prepared by: SWCA Environmental Consultants U.S. Army Corps of Engineers, Omaha District Environmental Resources and Missouri River Recovery Program Plan Formulation Section Planning Branch, CENWO-PM-AC 1616 Capitol Avenue Omaha, Nebraska 68102-4901 MITIGATED FINDING OF NO SIGNIFICANT IMPACT SACAGAWEA PIPELINE-PARADIGM MIDSTREAM SERVICES-ND LLC GARRISON PROJECT, MCKENZIE and MOUNTRAIL COUNTIES, NORTH DAKOTA April 2016 Introduction: In accordance with the National Environmental Policy Act (NEPA) and implementing regulations, an addendum to the Environmental Assessment (EA): Sacagawea Pipeline, incorporated by reference herein, has been prepared to evaluate the effects of Paradigm Midstream Service- ND, LLC (Paradigm) proposed oil and gas pipeline project that would horizontally directionally drill (HOD) beneath U.S. Army Corps of Engineers (Corps) managed land at the Garrison Project in McKenzie and Mountrail Counties, North Dakota. Approximately 8,980 feet of the proposed pipeline system would pass underneath Lake Sakakawea via the installation of approximately 10,980 feet of welded steel pipeline. Because the proposed pipeline will require an easement and the permission mandated by 33 U.S.C § 408 (Section 408) to cross beneath Lake Sakakawea and associated lands managed by the Corps, the Corps must first determine that the proposed pipeline would not be injurious to the public interest and would not impair the usefulness of the Garrison Project/Lake Sakakawea Project. As such, the Corps was identified as a cooperating agency for the proposed project, with the Bureau of Indian Affairs (BIA) acting as the lead federal agency for the activity that crosses Fort Berthold Indian Reservation Lands. However, the BIA signed a Finding of No Significant Impact (FONS!) on August 25, 2015 prior to the Corps completing its review of the BIA's document. The Corps appealed the BIA's FONS! in a letter dated September 22, 2015 on the basis that further analysis was needed to better understand impacts of the proposed activity relative to the Corps' authorities and management responsibilities. As a result, the Corps completed an addendum in close coordination with SWCA, the Environmental Consultants that authored the original EA for the BIA. This EA Addendum has been completed in accordance with the Council on Environmental Quality (CEQ) regulations in Section 1506.5(a) and 1506.5(b) which allows an applicant to prepare an EA for a federal action. The Corps has independently evaluated and verified the information and analysis undertaken in the EA Addendum and takes full responsibility for the scope and content contained herein. The Corps will incorporate findings within this document as part of complying with environmental laws and as stipulations to issue a real estate easement to Paradigm for the proposed activity. Project Summary: Paradigm proposes to construct 70 miles of two co-located 16-inch pipelines to transport crude oil and natural gas produced by Bakken Field wells from McKenzie County to rail and pipeline transmission locations in Mountrail County. The entire pipeline project would span privately owned lands, state trust lands, Fort Berthold Indian Reservation lands (Reservation) and Corps-regulated lands (e.g. federally regulated, fee surface, allotted and tribal lands). This Addendum assesses only those impacts relevant to the approximately 8,980 feet of the proposed pipeline system that would pass underneath Lake Sakakawea. Upon completion of construction , the pipeline would be commissioned and operated by Phillips 66. Alternatives: Three action alternatives were considered in the BIA's EA in order to meet the purpose and need for the proposed pipeline project. One alternative was to string the pipeline underneath the Four Bears Bridge. This alternative was dismissed due to maintenance concerns and potential threat to human safety. Trenching the pipeline into the bottom of the lake was also discussed and eliminated because HOD is an environmentally safer method of making the crossing and is the method prescribed by the Corps in the Garrison Oil and Gas Management Plan. The remaining alternatives that were evaluated in detail include (1) the Applicant's Proposal to construct the pipeline project with interagency coordination and implement recommended mitigation measures (Preferred Alternative) and (2) the No Action Alternative. Preferred Alternative: Implementation of the preferred alternative would allow for the transport of oil and natural gas from producing wells to markets. The route of the entire pipeline would originate in at the proposed Paradigm CDP Facility in McKenzie County 2.34 miles directly south of Keene, North Dakota and enters the Reservation from the west in the NE% Section 22, T151 N, R96W; then travels east approximately 5.85 miles within McKenzie County. The pipeline route then crosses under Lake Sakakawea and travels northeasterly across the Van Hook peninsula for approximately 18.19 miles, and exits the Reservation at a point east of Newtown in the NE% Section 10, T152N, R92W. The system would continue north then east across private lands terminating south west of Palermo, North Dakota. Under the preferred alternative, only minor and temporary surface disturbances such as foot traffic and laying of guide wire would occur on Corps-managed lands. Trenching would occur along the length of the Sacagawea Pipeline Project in upland-classified areas with the exception of Corps-managed lands. The preferred alternative would install approximately 10,980 feet of welded steel pipeline no less than 100 feet under Corps-managed lands by HDD. The proposed project would be designed, constructed, operated and maintained in a manner that meets applicable industry standards and regulatory requirements. Summary of Environmental Impact: According to BIA's EA the preferred alternative would result in no adverse impacts to any federally-listed threatened or endangered species or their habitat. The U.S. Fish and Wildlife Service (USFWS) has concurred with the Biological Assessment's finding that the project "may affect, but is not likely to adversely affect' the whooping crane (Grus americana), piping plover (Charadrius melodus) and it's critical habitat, interior least tern (Stema anti!larum) and pallid sturgeon (Scaphirhynchus a/bus). See Appendix F of BIA's EA for USFWS concurrence. In accordance with the Migratory Bird Treaty Act (16 U.S.C. § 703-712, 709 is omitted) and Bald and Golden Eagle Protection Act (16 U.S.C. § 668-668d, 54 Stat. 250), impacts to migratory birds , bald eagles (Haliaeetus leucocephalus) and golden eagles (Aquila chrysaetos) would be avoided by constructing the project outside of their breeding season. The preferred alternative would result in no impacts to any properties listed, proposed for listing, eligible for listing or potentially eligible for listing in the National Register of Historic Places. A Class Ill inventory of the project area was conducted and as the lead federal agency, BIA reached a determination of "no historic properties affected' for the proposed Pipeline Project. Areas along the 70-mile long, 100-foot wide corridor would be temporarily disturbed by proposed construction activities. The impacts associated with the proposed project construction are short term and minor (i.e., noise, earth disturbance, vegetation removal, increased traffic, etc.). Of the three alternatives considered, the preferred alternative would be implemented because it can be reasonably constructed, meets the projects purpose and need, incorporates sound mitigation, does not impair the Garrison Project from meeting its authorized purposes (Section 408) and is consistent with the Corps' commitment to the protection of the nation's environment. Mitigation Measures: Implementation of the preferred alternative as summarized in Section 1.2.2 of this EA Addendum would allow the Corps to issue the real estate easement to Paradigm, and is based on the impact analysis contained in the Addendum EA. The analysis shows that there will be no undue or unnecessary environmental impacts to the environment caused by construction, reclamation, operation and maintenance or abandonment of the pipeline while adhering to the plans of development (POD) and stipulations set forth under the real estate easement. Mitigation measures unique to Corps-managed lands derived from the Addendum EA are summarized in the Table below. All measures in this Table will be attached to the real estate easement and will be required to be adhered to in order to construct, operate and maintain the proposed project. Env1ronmenta .
