NR 440.684(1) (1) Applicability and designation of affected facilities.

NR 440.684(1)(a) (a) The provisions of this section are applicable to the following affected facilities that process natural gas: each sweetening unit, and each sweetening unit followed by a sulfur recovery unit.

NR 440.684(1)(b) (b) Facilities that have a design capacity less than 2 long tons per day (LT/D) of hydrogen sulfide (H2S) in the acid gas (expressed as sulfur) are required to comply with sub. (8) (c) but are not required to comply with subs. (3) to (7).

NR 440.684(1)(c) (c) The provisions of this section are applicable to facilities located on land and include facilities located onshore which process natural gas produced from either onshore or offshore wells.

NR 440.684(1)(d) (d) The provisions of this section apply to each affected facility identified in par. (a) which commences construction or modification after January 20, 1984.

NR 440.684(1)(e) (e) The provisions of this section do not apply to sweetening facilities producing acid gas that is completely reinjected into oil-or-gas-bearing geologic strata or that is otherwise not released to the atmosphere.

NR 440.684(2) (2) Definitions and symbols.

NR 440.684(2)(a) (a) As used in this section, terms not defined in this subsection have the meanings given in s. NR 440.02.

NR 440.684(2)(a)1. 1. “Acid gas” means a gas stream of hydrogen sulfide (H2S) and carbon dioxide (CO2) that has been separated from sour natural gas by a sweetening unit.
