Section 326IAC8-9-3. Definitions

   The following definitions apply throughout this rule:

(1) "Condensate" means hydrocarbon liquid separated from natural gas that condenses due to changes in the temperature or pressure, or both, and remains liquid at standard conditions.

(2) "Custody transfer" means the transfer of produced petroleum and condensate, or both, after processing or treatment, or both, in the producing operations, from storage vessels or automatic transfer facilities to pipelines or any other forms of transportation.

(3) "Fill" means the introduction of VOL into a storage vessel but not necessarily to complete capacity.

(4) "Gasoline service station" means any site where gasoline is dispensed to motor vehicle fuel tanks from stationary storage vessels.

(5) "Maximum true vapor pressure" means the equilibrium partial pressure exerted by a volatile organic liquid. The maximum true vapor pressure of VOLs stored at or above the ambient temperature shall correspond to the highest calendar month average storage temperature and shall be determined as follows:

(A) Maximum true vapor pressure for VOLs stored at or above the ambient temperature shall be determined using the following procedures:

(i) For gasolines and naphtha, either of the following:

(AA) Figures 17A and 17B, American Petroleum Institute Publication 2517, Third Edition, February 1989, with addendum, May 1994*.

(BB) Figure 4.3-6, AP-42*, Compilation of Air Pollutant Emission Factors, Volume I (Stationary Point and Area Sources), Fourth Edition, September 1985*.

(ii) For crude oils, either of the following:

(AA) Figures 18A and 18B, American Petroleum Institute Publication 2517, Third Edition, February 1989, with addendum, May 1994*.

(BB) Figure 4.3-5, AP-42*, Compilation of Air Pollutant Emission Factors, Volume I (Stationary Point and Area Sources), Fourth Edition, September 1985*.

(iii) For VOLs, other than those in item (i) or (ii), procedures on page D-146, Vapor Pressures, Critical Temperatures, and Critical Pressures of Organic Compounds, Handbook of Chemistry and Physics, 51st Edition, 1970-1971, Chemical Rubber Company*.

(iv) Maximum true vapor pressure for VOLs stored at or above ambient temperatures shall be determined at the following temperatures:

(AA) In Lake and Porter Counties, seventy-three (73) degrees Fahrenheit.

(BB) In Clark and Floyd Counties, seventy-seven and seven-tenths (77.7) degrees Fahrenheit.

(B) Alternatively, the owner or operator or the department and the U.S. EPA may require measurement of vapor pressure. ASTM Method D323-92* or a method acceptable to the department and U.S. EPA shall be used. If a discrepancy exists between the results obtained from methods in clause (A) and methods used in this clause, the results in this clause shall prevail.

(6) "Petroleum" means the crude oil removed from the earth and the oils derived from tar sands, shale, and coal.

(7) "Petroleum liquids" means petroleum, condensate, and any finished or intermediate products manufactured in a petroleum refinery.

(8) "Reid vapor pressure" means the absolute vapor pressure of volatile crude oil and volatile nonviscous petroleum liquids except liquified petroleum gases as determined by the following methods:

(A) For gasoline, only, ASTM D323-82**.

(B) For gasoline-ethanol blends, ASTM D-5190**, ASTM D-5191**, ASTM 5482**.

(9) "Vessel" means each tank, reservoir, or container used for the storage of VOLs but does not include either of the following:

(A) Frames, housing, auxiliary supports, or other components that are not directly involved in the containment of liquids or vapors.

(B) Subsurface caverns or porous rock reservoirs.

(10) "Volatile organic liquid" or "VOL" means any organic liquid that can emit volatile organic compounds (VOCs) into the atmosphere except those VOLs that emit only those compounds that the department has determined do not contribute appreciably to the formation of ozone.

(11) "Waste" means any liquid resulting from industrial, commercial, mining, or agricultural operations, or from community activities that is discarded or is being accumulated, stored, or physically, chemically, or biologically treated prior to being discarded or recycled.
