NR 440.17. NR 440.27(2)(L)(L) “Vapor recovery system” means a vapor gathering system capable of collecting all hydrocarbon vapors and gases discharged from the storage vessel and a vapor disposal system capable of processing such hydrocarbon vapors and gases so as to prevent their emission to the atmosphere. NR 440.27(3)(3) Standard for volatile organic compounds (VOC). NR 440.27(3)(a)(a) The owner or operator of any storage vessel to which this section applies shall store petroleum liquids as follows: NR 440.27(3)(a)1.1. If the true vapor pressure of the petroleum liquid, as stored, is equal to or greater than 78 mm Hg (1.5 psia) but not greater than 570 mm Hg (11.1 psia), the storage vessel shall be equipped with a floating roof, a vapor recovery system or their equivalents. NR 440.27(3)(a)2.2. If the true vapor pressure of the petroleum liquid as stored is greater than 570 mm Hg (11.1 psia), the storage vessel shall be equipped with a vapor recovery system or its equivalent. NR 440.27(4)(a)(a) Except as provided in par. (d), the owner or operator subject to this section shall maintain a record of the petroleum liquid stored, the period of storage, and the maximum true vapor pressure of that liquid during the respective storage period. NR 440.27(4)(b)(b) Available data on the typical Reid vapor pressure and the maximum expected storage temperature of the stored product may be used to determine the maximum true vapor pressure from nomographs contained in API Publication 2517, incorporated by reference in s. NR 440.17, unless the department specifically requests that the liquid be sampled, the actual storage temperature determined, and the Reid vapor pressure determined from one or more samples. NR 440.27(4)(c)(c) The true vapor pressure of each type of crude oil with a Reid vapor pressure less than 13.8 kPa (2.0 psia) or whose physical properties preclude determination by the recommended method is to be determined from available data and recorded if the estimated true vapor pressure is greater than 6.9 kPa (1.0 psia). NR 440.27(4)(d)(d) The following are exempt from the requirements of this subsection: NR 440.27(4)(d)1.1. Each owner or operator of each affected facility which stores petroleum liquids with a Reid vapor pressure of less than 6.9 kPa (1.0 psia) provided the maximum true vapor pressure does not exceed 6.9 kPa (1.0 psia). NR 440.27(4)(d)2.2. Each owner or operator of each affected facility equipped with a vapor recovery and return or disposal system in accordance with the requirements of sub. (3).

NR 440.28NR 440.28 Storage vessels for petroleum liquids for which construction, reconstruction or modification commenced after May 18, 1978, and prior to July 23, 1984. NR 440.28(1)(1) Applicability and designation of affected facility. NR 440.28(1)(a)(a) Except as provided in par. (b), the affected facility to which this section applies is each storage vessel with a storage capacity greater than 151,416 liters (40,000 gallons) that is used to store petroleum liquids for which construction is commenced after May 18, 1978.
