All terms used in this subpart that are not defined in this section have the

meaning given to them in the CAA and in subpart A of this part.

Alkali bypass means a duct between the feed end of the kiln and the preheater

tower through which a portion of the kiln exit gas stream is withdrawn and

quickly cooled by air or water to avoid excessive buildup of alkali, chloride

and/or sulfur on the raw feed. This may also be referred to as the "kiln exhaust

gas bypass".

Bagging system means the equipment which fills bags with portland cement.

Clinker cooler means equipment into which clinker product leaving the kiln is

placed to be cooled by air supplied by a forced draft or natural draft supply

system.

Continuous monitor means a device which continuously samples the

regulated parameter specified in §63.1350 of this subpart without interruption,

evaluates the detector response at least once every 15 seconds, and

computes and records the average value at least every 60 seconds, except

during allowable periods of calibration and except as defined otherwise by the

continuous emission monitoring system performance specifications in

appendix B to part 60 of this chapter.

Conveying system means a device for transporting materials from one piece

of equipment or location to another location within a facility. Conveying

systems include but are not limited to the following: feeders, belt conveyors,

bucket elevators and pneumatic systems.

Facility means all contiguous or adjoining property that is under common

ownership or control, including properties that are separated only by a road or

other public right-of-way.

Feed means the prepared and mixed materials, which include but are not

limited to materials such as limestone, clay, shale, sand, iron ore, mill scale,

cement kiln dust and flyash, that are fed to the kiln. Feed does not include the

fuels used in the kiln to produce heat to form the clinker product.

Finish mill means a roll crusher, ball and tube mill or other size reduction

equipment used to grind clinker to a fine powder. Gypsum and other materials

may be added to and blended with clinker in a finish mill. The finish mill also

includes the air separator associated with the finish mill.

Hazardous waste is defined in §261.3 of this chapter.

In-line kiln/raw mill means a system in a portland cement production process

where a dry kiln system is integrated with the raw mill so that all or a portion of

the kiln exhaust gases are used to perform the drying operation of the raw mill,

with no auxiliary heat source used. In this system the kiln is capable of

operating without the raw mill operating, but the raw mill cannot operate without

the kiln gases, and consequently, the raw mill does not generate a separate

exhaust gas stream.

Kiln means a device, including any associated preheater or precalciner

devices, that produces clinker by heating limestone and other materials for

subsequent production of portland cement.

Kiln exhaust gas bypass means alkali bypass.

Monovent means an exhaust configuration of a building or emission control

device (e. g. positive pressure fabric filter) that extends the length of the

equipment, that is not part of an in-line kiln/raw mill, used to grind feed to the

appropriate size. Moisture may be added or removed from the feed during the

grinding operation. If the raw mill is used to remove moisture from feed

materials, it is also, by definition, a raw material dryer. The raw mill also

includes the air separator associated with the raw mill.

Rolling average means the average of all one-minute averages over the

averaging period.

Run average means the average of the one-minute parameter values for a run.

in a manner consistent with good air pollution control practice for minimizing emissions.

§60.8 and §60.675 perform initial compliance testing within 60 days after achieving the maximum production rate

at which the affected facility will be operated, but not later than 180 days after initial startup and at such other

times as may be required by the Administrator under Section 114 of the Clean Air Act. Conduct test under such

conditions as the Administrator shall specify to the plant operator based on representative performance of the

affected facility. Use EPA Method 5 or Method 17 to determine compliance with the PM standard and use EPA

Method 9 to determine compliance with opacity standard.

• The sample volume shall be at least 1.70 dscm (60 dscf). For Method 5, if the gas stream being sampled is

at ambient temperature, the sampling probe and filter may be operated without heaters. If the gas stream is

above ambient temperature, the sampling probe and filter may be operated at a temperature high enough,

but no higher than 121°C (250°F), to prevent water condensation on the filter.

• For transfer points on belt conveyors and any other affected facility, including multiple storage bins with

combined stack emissions, the minimum total time of observations shall be 3 hours (30 6-minute averages).

The duration may be reduced from 3 hours to 1 hour if there are no individual readings greater than the

opacity limit and there are no more than 3 readings greater than the opacity limit for the 1-hour period.

• For baghouses that control emissions only form an individual enclosed storage bin, the duration of the

Method 9 observations shall be 1 hour (ten 6-minute averages).

• The minimum distance between the observer and the emission source shall be 4.57 meters (15 feet). The

observer shall, when possible, select a position that minimizes interference from other fugitive emission

sources (e.g., road dust). The required observer position relative to the sun (Method 9, Section 2.1) must be

followed. For affected facilities using wet dust suppression for particulate matter control, the spray

sometimes generates a visible mist. The water mist must not be confused with particulate matter emissions

and is not to be considered a visible emission. When a water mist of this nature is present, the observation

of emissions is to be made at a point in the plume where the mist is no longer visible.

• A 30-day notice is required prior to the initial performance test. If, after 30 days notice for an initially

scheduled performance test, there is a delay in conducting any rescheduled performance test required in this

section, the owner or operator of an affected facility shall submit a notice to the Administrator at least 7

days prior to any rescheduled performance test.
