Attachment 5: Memorandum Modeling Approach for Federal Conservation Units, June 24 2015 MEMORANDUM Modeling Approach for Federal Conservation Units Alaska LNG Project June 2015 The Alaska LNG Project plans to construct several stationary sources of air pollutant emissions as part of its plan to construct an integrated project with interdependent facilities for the purpose of liquefying natural gas for export and opportunity for in-state delivery. This document was developed in response to a meeting among the Alaska LNG Project team, the Federal Energy Regulatory Commission (FERC), Federal Land Managers (FLM), and the Alaska Department of Environmental Conservation (ADEC) on April 21, 2015. The modeling approach set forth herein is also intended to address many of the Resource Report 9 (RR9) issues identified in Attachment A of the FERC comments provided to Alaska LNG dated May 15, 2015. The modeling approach outlines requirements and impact assessments related to stationary sources proposed to be constructed as part of the Alaska LNG Project, including the Gas Treatment Plant (GTP) on the North Slope, compressor stations along the proposed pipeline, and the Liquefaction Facility along Cook Inlet. The approach addresses the modeling and analyses that would be required to support the review of the project under the federal National Environmental Policy Act. This approach does not address air quality permitting required by agencies that implement the Clean Air Act, although the analyses that are prepared in support of those applications would be used to support the NEPA process wherever availability of information aligns with the timing of the FERC application filing. As a part of the submittal to FERC, the Alaska LNG Project will be providing RR9, which requires documentation of emissions and impacts on air quality. FLMs have indicated their interest in reviewing impacts on Class I and sensitive Class II areas. This memorandum is submitted to the federal agencies to gain concurrence on the approach to the air quality analyses for the RR9 Report. This memo is also being submitted to the ADEC for review since many aspects of the modeling approach are also applicable to the air quality construction permit applications. The suggested approach is to develop a list of Class I and sensitive Class II federal conservation units (FCUs) then screen them for further evaluation. The FLMs have nominated the following list of FCUs for screening: National Park Service Gates of the Arctic NP, Lake Clark NP, Kenai Fjords NP, and Denali NPP Bureau of Land Management None Fish & ...
