; (B) the requisite physical assets along the value chain for ethane and other natural gas liquids; and (C) diversity in customers, both domestically and internationally. 3. Study and reports on building ethane and other natural-gas-liquids-related petrochemical infrastructure (a) Study (1) In general Not later than 1 year after the date of enactment of this Act, the Secretary of Energy (referred to in this section as the Secretary ), in consultation with the Secretary of Defense, the Secretary of the Treasury, and the heads of other relevant Federal departments and agencies and stakeholders, shall conduct a study assessing the potential national economic security impacts of building ethane and other natural-gas-liquids-related petrochemical infrastructure in the geographical vicinity of the Marcellus, Utica, and Rogersville shale plays in the United States. (2) Contents The study conducted under paragraph (1) shall include— (A) the identification of potential benefits of the proposed infrastructure to national and economic security, including the identification of potential risks to national and economic security of significant foreign ownership and control of United States domestic petrochemical resources; and (B) an examination of, with respect to the proposed infrastructure— (i) types of additional infrastructure needed to fully optimize the potential national security benefits; (ii) whether geopolitical diversity in areas to which the ethane and other natural gas liquids will be exported from the producing region would undermine or bolster national security; (iii) the necessity of evaluating the public interest with respect to exports of ethane, propane, butane, and other natural gas liquids, to ensure the potential strategic national and economic security benefits are preserved within the United States
