(3) Department means the New York State Department of Environmental Conservation.

(4) Facility capacity means the sum of the design capacities for each tank or other storage device (e.g., a tank trailer used for storage and not for an LNG transportation activity) at the LNG facility.

(5) Interstate transport of LNG means the transportation of LNG between a point in New York State and a point in another state or a foreign country, in either direction; or between points in New York State through another state or foreign country; or between points in other states or foreign countries through New York State.

(6) Intrastate transport of LNG means the transportation of LNG other than as described in the definition of interstate transport of LNG.

(7) L/CNG, also known as liquefied to compressed natural gas, means LNG which may be dispensed from its container as either a liquid (LNG) or as compressed natural gas (CNG).

(8) Liquefied natural gas, or LNG, means natural gas or synthetic gas composed primarily of methane (CH₄) cooled to its liquid state. For the purposes of this Part, LNG shall not mean liquefied petroleum gas.

(9) Liquefied natural gas facility or LNG facility means any structure or facility located on one or more contiguous or adjacent properties under common control that is used to store LNG in a tank system, or other storage device or to convert LNG into natural gas.

(10) Liquefied natural gas transportation activity or LNG transportation activity means the loading, unloading, or transportation, by whatever means, of LNG.

(11) NFPA means the National Fire Protection Association, or its successor.

(12) Natural gas means a fuel consisting of a mixture of mostly methane (CH₄) gas, other hydrocarbon gases, and trace amounts of non-hydrocarbon gases, which is stored and transported in a vapor state and under a wide range of pressures.

(13) Operator means any person who operates, controls, or supervises an LNG facility or who is responsible for the operation.

(14) Out-of-service, in relation to an LNG facility or portion thereof, means no longer receiving or dispensing LNG.

(15) Owner means any person who owns or has legal or equitable title to an LNG facility.

(16) Permit means an environmental safety permit issued by the department pursuant to article 23, title 17 of the Environmental Conservation Law and this Part.

(17) Person means any individual, corporation, partnership, association, cooperative or otherwise, trust or estate, governmental agency, authority, public benefit corporation, municipality or agency thereof, board or commission, or other public or private legal entity.

(18) Pre-existing facility means an LNG facility in actual use and operation on September 1, 1976 that is exempt from the permit requirements of this Part and operates pursuant to a department order.

(19) SEQRA means the State Environmental Quality Review Act set forth in article 8 of the Environmental Conservation Law, and implemented by Part 617 of this title.

(20) Spill or spillage means any escape of LNG in liquid form from the containers employed in the normal course of storage, transfer, processing, or use of LNG.

(21) Statement of compliance means a two-part document containing the following components. In part one, a State-licensed Professional Engineer authorized to practice engineering in the State pursuant to article 145 the State Education Law, on behalf of an applicant for a permit, attests by signature and seal that the design of the proposed LNG facility meets the applicable provisions of Federal Pipeline Safety standards, applicable provisions of the Public Service Commission’s regulations in 16 NYCRR, and the Uniform Fire Prevention and Building Code of the State. In part two, the owner of the facility attests that the facility will be operated in accordance with all applicable law, regulations, standards, and requirements.

(22) Tank means the main storage container of a tank system. Each section of a compartmented tank will be treated as an individual tank.

(23) Tank design capacity means the nominal amount of LNG that a tank is designed to hold as determined by the tank manufacturer. If a certain portion of a tank is unable to store LNG (for example, electrical equipment or other interior components take up space), the design capacity of the tank is thereby reduced.

(24) Tank system means a stationary device designed to store LNG that is constructed of non-earthen materials that provide structural support. This term includes all associated piping and ancillary equipment.

(25) Underground storage tank or UST means a tank for which 10 percent or more of the tank design capacity is beneath the surface of the ground. This term does not include a tank situated in an underground vault or other area making the tank fully available for inspection.

(1) An on-board LNG fuel tank used to power an LNG-fueled vehicle or vessel shall not constitute an LNG facility.

(2) LNG delivery tank trucks, when attached to a natural gas pipeline for the purpose of short-term pipeline-pressure regulation, shall not constitute LNG facilities if such tank trucks remain connected to the pipeline for less than 72 hours per event, and no more frequently than one such event during any 30 day period.

(3) The movement of LNG within the boundaries of an LNG facility shall not constitute intrastate transport of LNG.

(4) The movement of an LNG-fueled vehicle or vessel with an on-board LNG fuel tank used to power such vehicle or vessel shall not constitute intrastate transport of LNG.

(5) A pre-existing facility may continue to operate, without the need to obtain a permit, provided that:

(6) The delivery of LNG to alleviate an emergency, as defined in section 621.2(j) of this Title, shall not constitute intrastate transport of LNG, if the department has issued an emergency authorization pursuant to section 621.12 of this Title. For the duration of such emergency, the equipment used to convert LNG into natural gas shall not constitute an LNG facility, unless such equipment is already an LNG facility under this Part. In an emergency, the requirements of section 621.12 of this Title must be met.
