PROPOSED RULES

(c)petroleum storage and transfer units with a total storage capacity exceeding 300,000 barrels.

(16)"Prime coat" means the first film of coating applied to a surface to protect it or to prepare it to receive subsequent coatings.

(17)"Reasonably available control technology" (also denoted as RACT) means the lowest emission limit which a particular source is capable of meeting by the application of control technology that is reasonably available considering technological and economic feasibility.  It may require technology which has been applied to similar, but not necessarily identical, source categories.

(18)"Reid vapor pressure" means the absolute vapor pressure of volatile crude oil and volatile nonviscous petroleum liquids except liquefied petroleum gases as determined by American Society for Testing and Materials, Part 17, 1973, D-323-72 (reapproved 1977).

(19)"Shutdown" means the cessation of operation of a source or a part thereof or emission control equipment.

(20)"Solvent" means organic materials which are liquid at standard conditions and which are used as dissolvers, viscosity reducers, or cleaning agents.

(21)"Standard conditions" means a temperature of 68°F and pressure of 29.92 inches of mercury.

(22)"Stage I", means vapor control systems that minimize, collect, and transfer vapors in a gasoline storage tank, displaced by the incoming gasoline, which are routed through pipes and hoses back into the tank truck tank to be transported to where the truck is loaded and the vapors are recovered or destroyed. Vent lines on storage tanks with vapor control systems use pressure release valves or flow restrictors to minimize releases to the atmosphere.

(22)(23)"Startup" means the setting in operation of a source or emission control equipment.

(23)(24)"Substrate" means the surface to which a coating is applied.

(24)(25)"Topcoat" means the final films of coating applied in a multiple or single coat operation.

(25)(26)"True vapor pressure" means the equilibrium partial pressure exerted by a petroleum liquid as determined in accordance with methods described in American Petroleum Institute Bulletin 2517, "Evaporation Loss from Floating Roof Tanks," 1962.

(26)(27)"Vapor collection system" means a vapor transport system which uses direct displacement by the liquid loaded to force vapors from the tank into a vapor control system.

(27)(28)"Vapor control system" means a system which prevents release to the atmosphere of at least 90 percent by weight of organic compounds in the vapors displaced from a tank during the transfer of gasoline.

(28)(29)"Volatile organic compound" (also denoted as VOC) means any compound of carbon whose volatile content can be determined by the procedure described in Rules .0913 or .0939 of this Section excluding any compound that is listed under 40 CFR 51.100(s) as having been determined to have negligible photochemical reactivity.

Authority G.S. 143-215.3(a)(1).

15A NCAC 02D .0902APPLICABILITY

(a)  The rules in this Section do not apply except as specifically set out in this Rule.
(b)  Regardless of any other statement of applicability of this Section, this Section does not apply to:
(1)sources whose emissions of volatile organic compounds are not more than 15 pounds per day, except that this Section does apply to the manufacture and use of cutback asphalt and to gasoline service stations or gasoline dispensing facilities regardless of levels of emissions of volatile organic compounds;
(2)sources whose emissions do not exceed 800 pounds of volatile organic compounds per calendar month and that are:

(A)bench-scale, on-site equipment used exclusively for chemical or physical analysis for quality control purposes, staff instruction, water or wastewater analyses, or non-production environmental compliance assessments;

(B)bench-scale experimentation, chemical or physical analyses, training or instruction from not-for-profit, non-production educational laboratories;

(C)bench-scale experimentation, chemical or physical analyses, training or instruction from hospitals or health laboratories pursuant to the determination or diagnoses of illness; or

(D)research and development laboratory activities provided the activity produces no commercial product or feedstock material; or

(3)emissions of volatile organic compounds during startup or shutdown operations from sources which use incineration or other types of combustion to control emissions of volatile organic compounds whenever the off-gas contains an explosive mixture during the
