In addition, the primary and secondary crushers of the on-site nonmetallic mineral processing plant, regardless of whether they precede the raw material storage, are not subject to this subpart. Furthermore, the first conveyor transfer point subject to this subpart is the transfer point associated with the conveyor 67 FR 16614, Apr. 5,2002; 67 FR 72584, Dec. 6,20021 

### Q 63.1341 Definitions. 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a duct between the feed end of the kiln and the preheater tower through which a portion of the kiln exit gas stream is withdrawn and quickly cooled by air or water to avoid excessive buildup of alkali, chloride andlor sulfur on the raw feed.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. Bin means a manmade enclosure for storage of raw materials, clinker, or finished product prior to further processing at a portland cement plant. 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 

### 6 63.1 350 of this subpart without interruption, evaluates the detector response at least once every 15seconds, 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. Conveyingsystem 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. Conveyingsystem transfer point means a point where any material including but not limited to feed material, fuel, clinker or product, is transferred to or from a conveying system, or between separate parts of a conveying system. Dioxins and furans (D/F) means tetra-, penta-, hexa-, hepta-, and octachlorinated materials, whichincludebut 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 dots not include the fuels used in the kiln to pmduce 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. dypsum 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. Greenfield kiln, in-line kiIn/raw mill, or raw marerial dryer means a kiln, in-line kildraw mill, or raw material dryer for which construction is commenced at a plant site (where no kilns and no in-line kildraw mills were in operation at any time prior to March 24.1998) after March 24,1998. Hazardous waste is defined in 

### 8 261.3 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
sothat 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 clinkerby heating limestone and other materials for subsequent production of portland cement. Kiln exhaust gns 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 structure and has a width very small in relation to its length (i. e., length to width ratio is typically greater than 5:l). The exhaust may be an open vent with or without a roof, louvered vents, or a combination of such features. New brownfield kiln, in-line kiln raw mill, or raw material dryer means a kiln, in-line kilnlraw mill or raw material dryer for which construction is commenced at a plant site(where kilns and/or in-line kilnlraw mills
were in operation prior to March 24, 1998) after March 24, 1098. One-minute averoge means the average of thermocouple or other sensor responses calculated at least every 60 seconds from responses obtained at least once during each consecutive 15 second period.
Portland cement plant means any facility manufacturing portland cement. Raw ntnterinl dyer means an impact dryer, drum dryer, paddle-equipped rapid dryer, air separator, or other equipment used to reduce the moisture content of feed materials.
Rnw ntill means a ball and tube mill, vertical roller mill or other size reduction equipment, that is not part of an in-line kilnlraw mill, used to gnnd feecl 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. TEQ means the international method of expressing toxicity equivalents for dioxins and furans as defined in U.S. EPA, Interim Procedures for Estimating Risks Associated with Exposures to Mixtures of Chlorinated Dibenzo-pdioxins and dibenzofurans (CDDs and CDFs) and 1989 Update, March 1989.

D. 

### Justification
1. 

### Background
'Ihis facility manufactures Portland cement. Raw material, which provides the necessary composition of silica, calcium, 

## iron, alumina, etc., is ground to a 

### he texture and is heated 

### in
one of two kilns. The heated material, referred to 

## as clinker, is ground to a finer 

### size along with other additives such 

## as gypsum,resulting in Portland 

## cement. The product is loaded into trucks or rail cars or is sent elsewherefor bagging. Dust collection control is employed throughoutthe process. Except 

### kiln 

# #5 dust collection is performed with fabric filters (i.e., dust collectors and baghouses). An electrostatic precipitator (ESP) provides dust control for kiln 

### #2.
2. Rationale for Selection of PerformanceIndicator
Visible emissions observations are deemed a good 

### performance indicator since the findings
are quickly obtained and are indicativeof the dust collectors' efficiency. Visible emissions will not be 

### observed exiting a properly operating particulate matter control device. Conversely, such emissionswill become visible if a dust collector is not kctiming satisfactorily.

3. 

### Rationale for Selection of Indicator Level
The selected indicator range is no visible emissions. Using an EPA 

### Reference Method 22- like protocol, a "see" or "no-see" method for evaluating dust collectors' efficiency was selected at this facility because: (1) 

### it is an approved method, (2) it is quickly performed, (3) 

### it 

### can be 

### used to evaluate the many dust collectors functioning throughout the facility, (4) 

### it does not require a Method 9 

### certified observer, 

### (5) it 

### can be 

### used while the process is operating, and (6) 

### it has the advantage of detecting a problem at a distance instead of relying
on close examination of gauges or similar metering devices. The scheduled daily inspection of each point source will be 

### over a one-minute period. This time interval will be 

### sufficient to provide reasonable assurancethat the pollution control device is operating satisfactorily. Secondary observations and reporting of visible emissions by workers throughout the remainder of the day will provide additional assurance of compliance.

D. 

### Justification

1. Background
Kilns are integral in the cement manufacturing process. During the pyroprocess, raw material is heated to extreme temperatures and converted into clinker. The heating process involves many chemical reactionsthat are controlled by closely monitoring and adjusting the chemistry of the raw material and parameters of the heating process.
Clinker formed in the kilns is then transferred to clinker coolers where it is rapidly cooled. The cooling "locks in" 

### the chemical structures and allows the product to be 

### handled. Subsequently, the clinker is ground with additives in finish mills. The fmal product of the grinding process is Portland cement.
At Mountain Cement Company, there are two kilns; both ofwhich are equipped with a clinker cooler. The exhaust gases 6om the kilns traverse air pollution control devices designed to remove dust fiom the gases. The control device for Kiln #I is a multicompartmentbaghouse which contains 2,268 fabric filter bags. Kiln #2 uses an electrostatic precipitator for removing dust 6om its exhaust gases. Dust removed from the gases from both kilns is either returned to the process or wasted. The cleaned gases are emitted into the atmospherethrough exhaust stacks. Both kilns are equipped with their own stack. Continuous emissionsmonitors situated on each stack analyze the gases for certain pollutants and the opacity of the emissions. The latter serves as a surrogate measurement for the amount of particulate matter contained in the gases.

### "Exceedence" shall mean a condition that is detectedby monitoring that provides data in terms of an emission limitation or standard and that indicatesthat emissions (or opacity)
are greater than the applicable emission limitation or standard (or less than the applicable standard in the case of a percent reduction requirement) consistent with any averaging period specified for averaging the results of the monitoring."Excursion" shall rnean a departure hm an indicator range established for monitoring under this part, consistent with any averaging period specified for averaging the results of the monitoring.
"Inherentprocess equipment" means equipment that is ntcessary for the proper or safe functioning of the process, or material recovery equipment that the owner or operator documenls is installed and operated primarily for purposes other than compliance with air pollution regulations. Equipment that must be operated at an efficiency higher than that achieved during normal process operations in order to comply with the applicable emission limitation or standard is not inherent process equipment. For the purposes of this part, inherent process equipment is not considered a control device. "Mnjor source" means any stationary source (or any group of stationary sources that are located on one or more contiguous or adjacent properties, and are under common control of the same person or persons under common control) belonging to a single major indushial grouping and that is described in paragraphs (i), (ii), or (iii) of this definition. For the purpose of defining "major source", a stationary source (orgroup of stationary
sources shall be considered part of a single industrial grouping if all of the pollutant emitting activities, at such source or group of
sources on contiguous or adjacent properties belong to the same Major Group (i.e., all have the same two-digit code) as described in the Standard lnldustrialClassification Manual, 1987. (i) A major source under section 1 12 of the Act, which is defined as: (A) For pollutanrs other than radionuclides, any stationary source or group of stationary
sources located within a contiguous area and under common control that emits or has the potential to emit, in the aggregate, 10 tons per year (tpy) or more of any hazardous air pollutant which has been listed pursuant to section 1 I2(b) of the Act, 25 tpy or more of any combination of such hazardous air pollutants, or such lesser quantity as the EPA may establish by rule.

Dear 

# Mr. Sansing: We are writing 

# inresponse to your request dated September 8,2003 for 

# an alternative testing approach tobe

# used 

# at theMountain Cement Company facility located

# in Laramie, Wyoming. As we understand 

# it, Mountain Cement is subject to the requirements

# of40 CFR 60, Subpart LLL, National Emission Standards for Hazardous 

## Air Pollutants

# hm the Portland Cement Manufacturing Industry. As such, Mountain Cement is required to conduct performance testing under 463.1349@)(2) using Method 9 (40 CFR 

## Part 60, Appendix A) to determine compliance 

# with opacity 

## limits set forth 

## in 463.1348. 

# I In your request, you explain that Mountain Cement has a number of emission 'sources that
are enclosed 

## within buildings 

# and propose in lieu of conductingMethod 9 testing of individuals affected sources inside the buildings to conduct Method 

## 22 (40 CFR Part 60, Appendix A) observations f& visible emissions on the sides and roof of the buildings 

## as well 

# as Method opacity observations of the building vents. Although Subpart LLL of Part 

## 63 does not specifically address alternative test methods for materials handling equipment located inside buildings, we are willing to defer to the approach under the Standards for Performance for Nonmetallic Mineral Processing Plants (40 CFR Part 

## 60, Subpart 000, 

## 460.672 (e)) which is identical to what you have proposed, and which states: "the building enclosing the affected facility or facilities must comply with the following emission limits: (1) 

## No owner or operator shall cause to discharge into the atmosphere fiom any building enclosing any transfer point on a conveyorbelt or any other affected facility any visible fugitive emissions except emissions fiom a vent as defined in 560.671. (2) No owner or operator shall
cause to be discharged into the atmosphere from any vent of any building enclosing any transfer point on a conveyor belt or any other affected facility any emissions which exceed the stack emissions limits

# ..."

In specific, to apply this approach,Mountain Cement in Laramie,Wyoming must meet the following two requirements:
(1) 

## For each building enclosing materials handling and conveyingsystem equipment affected sources, conduct observations for visible emissions other than condensed water vapor

# with each side ofthe building and roofbeing observed for at least 15minutes 

# each. The observationposition shouldbe at least 15,but not more 1,320 feet from 

# kach side of the building 

# with the sun or other light source gmerally at the observer's back.
(2) For each emission point (defined 

# as 

# avent under 960.671) from a building enclosing

c 

## materials handling and conveying system equipment affected sources, conduct'opacity observations using Method 

# 9. Each vent must be observed for at least 3 

## hours to obtain at least thirty, 

## 6-minute averages. The duration of the Method 9 performance test may be reduced to l-hour if (a) there are no individual readings greater than 10percent opacity and (b) 

## there are no more than three readings of 10percent for the first l-hour period.
The results of the (1) Method 22 observationsof any building must show no visible emissions and (2) Method 9 

## observations of any vents must meet the opacity limits set forth in 963.1348.
If you have any questions regarding this alternative, please contact Robin Segall of my staff at 9 19-541-0893or segall.robin@epa.gov. Sincerely,
