N.M. Admin. Code § 20.11.65.7 - DEFINITIONS

In addition to the definitions in 20.11.65.7 NMAC the definitions in 20.11.1 NMAC apply unless there is a conflict between definitions, in which case the definition in 20.11.65 NMAC shall govern.

A. "Active life" means the time from initial startup until final shut down of the facility. This would also include periods of scheduled or unscheduled maintenance, flow adjustments or system failure, all of which are subject to the provisions of 20.11.49 NMAC.

B. "Alternative method" means any method of sampling and analyzing for an air pollutant which is not a reference or equivalent method but which has been demonstrated to the EPA administrator's or the director's satisfaction, in specific cases, to produce results adequate for the determination of compliance.

C. "Contaminated" means a condition resulting from seepage, drainage, or flow of gaseous or liquid substances from activities such as a leaking underground storage tank, usually detected by hydro-geologic investigations or underground storage tank excavation and removal.

D. "Cutback asphalt" means asphalt cement or other paving material, which has been diluted or blended with petroleum solvents such as kerosene, naphtha, diesel oil, gasoline, or similar petroleum distillate products.

E. "Decontamination facility" means a place where a portable or stationary treatment system is installed and operated to receive water, air, or other gaseous substances bearing VOC contaminants.

F. "Dispense" means to introduce organic liquids by temporary connection from a supply container, greater than 60 gallons capacity, into a receptor container, which is normally closed and sealed against spillage or evaporative loss.

G. "Equivalent approved by the director" means the authorization to substitute an alternative control process, which has been demonstrated to the satisfaction of the director to result in no greater emissions, than would occur with the control process otherwise required. The director may use federal EPA document AP-42 or any other reliable reference or manufacturers data in completing the evaluation of the proposed alternative.

H. "Equivalent method" means any method of sampling and analyzing for an air pollutant which is not a reference method but which has been demonstrated to the EPA administrator's or the director's satisfaction to have a consistent and quantitatively known relationship to the reference method, under specified conditions.

I. "Existing facilities" means those decontamination facilities, which were constructed and placed in operation prior to June 1, 1991.

J. "Gasoline" means a mixture of liquid hydrocarbons with Reid vapor pressure of 4.0 psi or greater which is suitable for use as a fuel in spark ignition internal combustion engines and includes oxygenated blends.

K. "Loading rack" means a gasoline loading facility, which was constructed prior to December 17, 1980, and it includes loading arms, pumps, meters, shutoff valves, relief valves, and other piping and valves necessary to fill tank trucks. Those constructed or refurbished after December 17, 1980, may be subject to 20.11.63 NMAC, New Source Performance Standards.

L. "Motor vehicle" means any wheeled conveyance propelled by an internal combustion engine and commonly operated on roadways and which has a fuel tank capacity exceeding 5.0 U.S. gallons (18.93 liters).

M. "New facilities" means those decontamination facilities, which are authorized by an authority-to-construct permit issued by the department and dated June 1, 1991 or later.

N. "Organic fluid" means any substance or mixture thereof, which is liquid at standard conditions and contains carbon compounds that act as volatile organic compounds.

O. "Oxygenate" means an oxygen-containing, ashless organic compound such as alcohol or ether, which may be used as a motor vehicle fuel or fuel supplement.

P. "Reference method" means any method of sampling and analyzing for an air pollutant as described in Appendix A to 40 CFR 60.

Q. "Regenerate" means to drive off or cause the release of adsorbed or absorbed VOC from the collection media of a pollution control device.

R. "Stationary container" shall mean any aggregation or combination of containers which is:

(1) possessed by one person;

(2) located so that any portion of such aggregation or combination of containers can be encompassed within a circle 300 feet in diameter; and

(3) was constructed prior to June 11, 1973; those constructed after June 11, 1973, may be subject to 20.11.63 NMAC, New Source Performance Standards.

S. "Strip" means to subject contaminated liquid to direct contact with a gaseous medium so that contamination products are transferred from the liquid to the gas, such as in a packed column.

T. "Submerged fill pipe" means any fill pipe, the discharge opening of which is entirely submerged when the fluid level is six (6) inches above the bottom of the container.

U. "Transportable container" means a gasoline or other organic fluid-containing vessel and its ancillary plumbing fixtures with a capacity greater than 500 gallons which is mounted on a truck or trailer chassis licensed for bulk movement of organic fluids by way of public roadways.

V. "Underground storage tank" means any single vessel buried or installed below ground and used for holding gasoline at a facility having an annual total volume of use or sale in excess of 100,000 gallons of gasoline.

W. "Vapor pressure" means the true vapor pressure of the fluid mixture vapors as could reasonably be expected under the actual storage conditions. This would be the equilibrium.

X. "Ventilation" means to evaporate and flush VOC's from contaminated soil by increasing soil temperature or exposing it to air, steam or any other working gases.

Y. "Volatile organic compound" or "VOC" means any organic compound which participates in atmospheric photochemical reactions; or which is measured by a federal EPA reference method, an equivalent method, an alternative method, or which is determined by procedures specified under any subpart of 40 CFR 60 of the federal Code of Regulations.
