    As used in this subpart, all terms not defined herein shall have the 
meaning given them in the Clean Air Act (CAA) or in subpart A of part 
60, and the following terms shall have the specific meanings given them.
    Capital expenditure means, in addition to the definition in 40 CFR 
60.2, an expenditure for a physical or operational change to an existing 
facility that:
    (a) Exceeds P, the product of the facility's replacement cost, R, 
and an adjusted annual asset guideline repair allowance, A, as reflected 
by the following equation: P = R x A, where:
    (1) The adjusted annual asset guideline repair allowance, A, is the 
product of the percent of the replacement cost, Y, and the applicable 
basic annual asset guideline repair allowance, B, divided by 100 as 
reflected by the following equation:

    A = Y x (B / 100);

    (2) The percent Y is determined from the following equation: Y = 1.0 
- 0.575 log X, where X is 2006 minus the year of construction; and
    (3) The applicable basic annual asset guideline repair allowance, B, 
is selected from the following table consistent with the applicable 
subpart:

necessary, flow-inducing devices that transport gas or vapor from a 
piece or pieces of equipment to a control device or back to a process.
    Connector means flanged, screwed, or other joined fittings used to 
connect two pipe lines or a pipe line and a piece of process equipment 
or that close an opening in a pipe that could be connected to another

    Double block and bleed system means two block valves connected in 
series with a bleed valve or line that can vent the line between the two 
block valves.
    Duct work means a conveyance system such as those commonly used for 
heating and ventilation systems. It is often made of sheet metal and 
often has sections connected by screws or crimping. Hard-piping is not 
ductwork.
    Equipment means each pump, compressor, pressure relief device, 
sampling connection system, open-ended valve or line, valve, and flange 
or other connector in VOC service and any devices or systems required by 
this subpart.
    First attempt at repair means to take action for the purpose of 
stopping or reducing leakage of organic material to the atmosphere using 
best practices.
    Fuel gas means gases that are combusted to derive useful work or 
heat.
    Fuel gas system means the offsite and onsite piping and flow and 
pressure

[[Page 525]]

control system that gathers gaseous stream(s) generated by onsite 
operations, may blend them with other sources of gas, and transports the 
gaseous stream for use as fuel gas in combustion devices or in-process 
combustion equipment, such as furnaces and gas turbines, either singly 
or in combination.
    Hard-piping means pipe or tubing that is manufactured and properly 
installed using good engineering judgment and standards such as ASME 
B31.3, Process Piping (available from the American Society of Mechanical 
Engineers, P.O. Box 2300, Fairfield, NJ 07007-2300).
    In gas/vapor service means that the piece of equipment contains 
process fluid that is in the gaseous state at operating conditions.
    In heavy liquid service means that the piece of equipment is not in 
gas/vapor service or in light liquid service.
    In light liquid service means that the piece of equipment contains a 
liquid that meets the conditions specified in Sec. 60.485a(e).
    In-situ sampling systems means nonextractive samplers or in-line 
samplers.
    In vacuum service means that equipment is operating at an internal 
pressure which is at least 5 kilopascals (kPa) (0.7 psia) below ambient 
pressure.
    In VOC service means that the piece of equipment contains or 
contacts a process fluid that is at least 10 percent VOC by weight. (The 
provisions of Sec. 60.485a(d) specify how to determine that a piece of 
equipment is not in VOC service.)
    Initial calibration value means the concentration measured during 
the initial calibration at the beginning of each day required in Sec. 
60.485a(b)(1), or the most recent calibration if the instrument is 
recalibrated during the day (i.e., the calibration is adjusted) after a 
calibration drift assessment.
    Liquids dripping means any visible leakage from the seal including 
spraying, misting, clouding, and ice formation.
    Open-ended valve or line means any valve, except safety relief 
valves, having one side of the valve seat in contact with process fluid 
and one side open to the atmosphere, either directly or through open 
piping.
    Pressure release means the emission of materials resulting from 
system pressure being greater than set pressure of the pressure relief 
device.
    Process improvement means routine changes made for safety and 
occupational health requirements, for energy savings, for better 
utility, for ease of maintenance and operation, for correction of design 
deficiencies, for bottleneck removal, for changing product requirements, 
or for environmental control.
    Process unit means the components assembled and connected by pipes 
or ducts to process raw materials and to produce, as intermediate or 
final products, one or more of the chemicals listed in Sec. 60.489. A 
process unit can operate independently if supplied with sufficient feed 
or raw materials and sufficient storage facilities for the product. For 
the purpose of this subpart, process unit includes any feed, 
intermediate and final product storage vessels (except as specified in 
Sec. 60.482-1a(g)), product transfer racks, and connected ducts and 
piping. A process unit includes all equipment as defined in this 
subpart.
    Process unit shutdown means a work practice or operational procedure 
that stops production from a process unit or part of a process unit 
during which it is technically feasible to clear process material from a 
process unit or part of a process unit consistent with safety 
constraints and during which repairs can be accomplished. The following 
are not considered process unit shutdowns:
    (1) An unscheduled work practice or operational procedure that stops 
production from a process unit or part of a process unit for less than 
24 hours.
    (2) An unscheduled work practice or operational procedure that would 
stop production from a process unit or part of a process unit for a 
shorter period of time than would be required to clear the process unit 
or part of the process unit of materials and start up the unit, and 
would result in greater emissions than delay of repair of leaking 
components until the next scheduled process unit shutdown.
    (3) The use of spare equipment and technically feasible bypassing of 
equipment without stopping production.

to verify that emissions from the equipment are below the applicable 
leak definition.
    Replacement cost means the capital needed to purchase all the 
depreciable components in a facility.
    Sampling connection system means an assembly of equipment within a 
process unit used during periods of representative operation to take

change in a physical quantity such as temperature, pressure, flow rate, 
pH, or liquid level.

organic liquids that are used in the process as raw material feedstocks, 
produced as intermediates or final products, or generated as wastes. 
Storage vessel does not include vessels permanently attached to motor 
vehicles, such as trucks, railcars, barges or ships.
    Synthetic organic chemicals manufacturing industry means the 
industry that produces, as intermediates or final products, one or more 
of the chemicals listed in Sec. 60.489.
    Transfer rack means the collection of loading arms and loading 
hoses, at a single loading rack, that are used to fill tank trucks and/
