1.0 EXECUTIVE SUMMARY

On March 12, 2010 the U. S. Environmental Protection Agency (US EPA) issued an 

Information Collection Request (the Tile ICR) to Dal Tile, Inc. Within the Tile ICR, Enclosure 2 

specified the emission sources and pollutants that were required to be tested and Enclosure 3, 

Table 1.1 Summary of Ceramic Tile Source Test Methods and Alternate Methods, specified the 

test methods and parameters for each pollutant to be tested. These enclosures are included as 

attachments to this report and can be located in Appendix L. 

Although the ICR requested that testing be performed for PM 2.5 and condensable PM, 

these tests were not performed due to an agreement reached between the tile industry and the 

US EPA. The Test Protocol that was submitted and approved reflects this, as there is no 

discussion of these tests. 

 On April 13, 2010, the Tile Council of North America (TCNA), through the offices of Guida, 

Slavich and Flores contracted with Entec Services to perform this testing at all TCNA member 

companies who had received the ICR. 

Testing was conducted at Dal Tile on December 13-16, 2010 by Mr. Lynn Beane, Mr. 

Kevin Rosenberg, Mr. Chuck Duncan IV and Mr. Ryan Fogg of Entec Services, Inc. 

Representing Dal Tile was Mr. Steve Willis who coordinated testing with plant production 

personnel. 

Testing on April 28–29, 2011 was conducted by Mr. Kevin Rosenberg and Mr. Tim 

Draheim. Dal Tile was again represented by Mr. Steve Willis who coordinated testing with plant 

production personnel. 

NOTE: Various nomenclatures were employed for the source names on field data 

sheets. The following terms shall be considered equivalent. 

Tile Dryer No. 5 – referred to as Roller Dryer 

Spray Dryer No. 1 (SD-1) – referred to as Spray Dryer (EPN-11)

2.0 SUMMARY OF TEST RESULTS 

 Emission testing was conducted on the following sources utilizing US EPA methods 1, 2, 

2f, 3, 3a, 4, 5, 23 and 29 of 40 CFR 60, Appendix A as indicated in the table below. 

EU ID Source Name/Control Device Test Methods 

SD-1 Spray Dryer No. 1/Wet Scrubber 1, 2f, 3a, 4, 23 

DC-5 Tile Dryer / No control device 1, 2, 3, 3a, 4, 23 

RK-1, RK-2, RK-5 AND 

RK-6 Bisque Roller Kilns / No control device 1, 2, 3, 3a, 4, 5, 23, 29 

RK-7, RK-8, RK-11 AND 

RK-12 Glost Roller Kilns / No control device 1, 2, 3, 3a, 4, 23, 29 

2.1 SAMPLING ISSUES AND METHOD DEVIATIONS 

 Testing on Spray Dryer (SD-1) was originally scheduled for Tuesday and Wednesday, 

December 14-15, 2010 but was postponed when initial flow measurements revealed cyclonic 

flow conditions in the stack. Cyclonic flow is described as flow primarily not vertical to the stack 

wall and exhibiting a mean yaw angle of greater than 20 degrees. Based on this information the 

facility elected to conduct testing utilizing EPA’s alternate test procedures – EMC draft guidance 

document 008r (January 2003). The facility was unable to meet recommendation 1 and 2 due 

to facility limitation of the mentioned guidance document. Sampling was completed on April 28-

29, 2011. 

 Guideline document GD-008r, “Particulate Emission Sampling in Cyclonic Flow”, 

provides three recommendations for addressing cyclonic flow sampling locations in the 

preferential order of application. The first is to find another location to sample which was not an 

option for this particular Spray Dryer. The second option is to install straightening vanes 

upstream of the sampling location, also not an option for Dal Tile on the Spray Dryer. Therefore, 

Dal Tile, Inc. received approval from US EPA to pursue sampling of the Spray Dryer duct for 

particulate and dioxin/furan emissions utilizing US EPA Reference Test Method 2F and 

Guideline Document GD-008r. 
Dal Tile, Inc. – El Paso, TX Project Nos. 210268 / 211169 

Page 8 of 30

 Preliminary measurements during the first mobilization to the facility indicated cyclonic 

flow at angles greater than 50o

 at seven of the twenty-four points. In communications between 

Mr. Peter Westlin of US EPA, OAQPS (Office of Air Quality Planning and Standards) and Mr. 

Troy Burrows, Entec Corporate Quality Manager, the decision was made to sample the stack 

treating all angles as being 50o

 or less. Utilizing the agreed upon procedures, the test crew 

sampled at each of the twenty-four points located according to US EPA Method One with a 

dwell time of ten minutes for a total run time of 240 minutes or four hours. The nozzle axis was 

aligned parallel with the stack axis and was not adjusted during the course of sampling. 

 Since point by point isokinetics were required by GD-008r, isokinetics were calculated 

using the pre-test velocity traverse data adjusted for the axial velocity. Many points were 

outside of the 90% ≤ %I ≤ 110% stated range of US EPA Method 5 using equation 5-8. Some 

angles were greater than those measured on the first mobilization, including a couple of points 

with a yaw angle of 80o

. These points skewed isokinetic sampling results. 

Additionally, the test crew mistakenly used the actual measured velocity head data to set 

sampling rates when the sampling rate should have been established using the resultant 

velocity head data. The effect of this was an approximately 10-12% higher sampling rate. 

 The ALS Environmental Sample Integrity Form for the Glost Roller Kiln method 29 

samples indicated a missing fraction identified as 5C. Fraction 5C is described in Reference 

Test Method 29 in section 8.2.9.3 as an optional 25 ml rinse using 8N HCl. The rinse is 

required only if the previous DI water rinse does not remove all visible signs of potassium 

permanganate (KMnO4). For run 1 on the Glost Roller Kilns, there were no visible stains (purple 

in color) remaining on the glassware. For the following two runs, slight staining required use of 

the 5C fraction. 

 No difficulties or problems, other than what is outlined above, were encountered during 

sampling on the above sources. The emissions test summaries on the following pages give a 

detailed summary of each test. No process data was provided thus emissions are not reported 

in kg/MG of product. The Company will submit process data and corresponding calculations as 

CBI (confidential business information) under separate cover.

3.0 PROCESS DESCRIPTION 

 No production data is included in this report. The Company will submit process data and 

corresponding calculations as CBI (confidential business information) under separate cover. 

The Dal-Tile manufacturing site located in El Paso, Texas produces ceramic wall tile. It 

is unlike any of the other major sources that received a stack testing ICR. Its raw materials mix 

is different, consisting primarily of talc, clays and glazing compounds. Further, it has an 

integrated wall tile firing processes consisting of a first step that produces an intermediate 

product known as “bisque,” and a second “glost” firing process. 

3.1 Raw Material Handling 

Talc and clays are delivered to the site by covered trucks or enclosed railcars, while the 

glazing compounds typically arrive in bulk bags. These raw materials contain either no, or very 

low naturally occurring, organic compounds. The body materials are stored in silos in the raw 

material storage building. 

3.2 Body Preparation 

Talc and clays are mixed with recycled green scrap, fired tile wastes, and water in large 

continuous ball mills to produce a wet slurry, or ‘slip’. Due to the high water content of the ‘slip’, 

no emissions result from the mixing process. The ‘slip’ is stored in underground tanks prior to 

processing through the spray dryer. The ‘slip’ is processed through the natural gas fired spray 

dryer to convert the slurry into granules (aka powder or prill). A water-based wet scrubber (EPN 

11) controls particulate emissions from the spray dryer operations. 

3.3 Pressing 

The body granules are conveyed to hydraulic presses that are used to form the various 

shapes and sizes of the product. The pressed tiles are moved by roller conveyors directly from 

the presses to the tile drying operation. 
Dal Tile, Inc. – El Paso, TX Project Nos. 210268 / 211169 

Page 18 of 30

3.4 Tile Drying 

Each press has its own associated roller dryer. These dryers, heated by natural gas, 

reduce the moisture in the pressed tiles and increase the tile temperature in preparation for 

firing in the kilns. Each roller dryer (Tile dryer) has its own separate exhaust stack venting to 

atmosphere. 

3.5 Kiln Firing 

The firing process at Dal-Tile/El Paso is different from the tile manufacturing processes 

at other Dal-Tile facilities and at other US manufacturers. The El Paso facility produces ceramic 

tile designed for use on walls and is both thinner and lighter (less dense) than other tile products 

(e.g., floor, mosaic, and/or quarry tile products). Due to the unique characteristics of the raw 

materials used to make wall tile at El Paso, it is necessary to use a double-fire process in order 

to obtain the desired finish of the glazed product. 

The pressed and dried tiles are conveyed directly from the roller dryer into the first-fire 

kiln. Each roller dryer has its own associated first-fire kiln. The product of the first-fire kiln 

process is called “bisque”. The fired bisque tiles are transferred via special cars to the glazing 

operations (see Sections 3.6 and 3.7 below). 

Following the glazing process, tiles are moved to the entrance of, and automatically fed 

into one of the second-fire kilns. This process is called glost firing. The bisque process has 

already converted the raw materials to ceramic tile and the glost process is simply firing the 

glaze compounds to create the finished product. 

Under normal operation, as required by the facility’s air permit, the exhausts from the 

combustion zone of the bisque kilns are combined with the exhausts from the combustion zone 

of the glost kilns and vented through a common stack (EPN 29). There are no pollution controls 

on the common stack. 

Since it was expected that the double-fire process would result in different 

concentrations of HAP emissions, for purposes of this testing program, the exhaust from the 

bisque kilns were measured separately from the exhaust from the glost kilns. The glost kilns 

exhaust testing was accomplished by venting the exhaust from each individual bisque kiln stack 
Dal Tile, Inc. – El Paso, TX Project Nos. 210268 / 211169 

Page 19 of 30

directly to atmosphere. Glost Kilns 7, 8, 11 and 12 were operated during this testing event. 

Likewise, the bisque kilns exhaust testing was accomplished by venting the exhaust from each 

individual glost kiln stack directly to atmosphere. Bisque Kilns 1, 2, 5, and 6 were operated 

during this testing event. 

3.6 Glaze Preparation 

The ceramic glaze material and stains arrive at the facility in sealed bags by truck. The 

glaze materials are mixed with clean water in small batch ball mills to achieve the desired 

moisture content. Stains are dispersed into different base glazes to create specific glaze colors. 

3.7 Gla8zing 

The cars with the fired bisque tiles are moved to the entrance of one of the six glaze 

lines. The fired bisque tiles are automatically fed onto the glaze conveyor lines and pass under 

bell (“waterfall”) or roto-color type glaze applicators. The glaze is deposited as a thin layer onto 

the tiles. Neither the bell nor the roto-color glaze application processes utilize aerosols and 

therefore, do not generate overspray. The glazed bisque tiles are stored temporarily in special 

cars in preparation for the next process, glost firing. 

3.8 Sorting and Shipping 

Fired glazed tiles are sorted and inspected at the sorting lines. Defective tiles are 

separated and transported to the fired tile scrap processing area for recycling/reuse into the 

body material formula. The finished, inspected tiles are packaged into cartons and stacked on 

pallets. The full pallets are moved to the storage area and staged for shipping.

4.0 REFERENCE METHOD TEST PROCEDURES 

 Emission rates were determined using US EPA Reference Test Methods 1, 2, 2F, 3, 3A, 

4, 5, 23 and 29 of US EPA 40 CFR 60, Appendix A and Emissions Measurement Center (EMC) 

Draft Guidance Document 008r. Calibration and quality assurance procedures of US EPA 40 

CFR Part 60, Appendix A and the “Quality Assurance Handbook for Air Pollution Measurement 

System” Volume III Stationary Source-Specific Methods were followed throughout the duration 

of field and laboratory testing for all methods. The most current version for each method (as 

described in the Federal Register) was used. 

 

4.1 US EPA REFERENCE TEST METHOD 1 - TRAVERSE POINT LAYOUT 

For Information on stack dimensions, traverse points, distance to disturbance and other 

relevant data, refer to the drawings presented in Figures 4-1 through 4-4, “Stack Drawing and 

Traverse Point Location”. 

 

4.2 US EPA REFERENCE TEST METHOD 2 – VELOCITY 

(Glost and Bisque Kilns, Tile Dryer)

The velocity of each gas stream was determined according to US EPA Reference 

Method 2 by reading the instantaneous velocity head with an inclined manometer at each 

sampling point with a calibrated S-type pitot. The stack pressure was measured with the static 

side of an S-type pitot tube. A calibrated pyrometer was used to measure stack temperature at 

each sampling point. All test data, worksheets, and spreadsheets presenting the calculations 

are included in Appendices A - D. Calibration procedures for the velocity equipment are located 

in Section 6.0 of this report. Pitot tube, thermocouple, and other measurement device 

calibration worksheets used for the test series are presented in Appendix I. 

4.3 US EPA REFERENCE TEST METHOD 2F – VELOCITY USING A THREEDIMENSIONAL PROBE (Spray Dryer No. 1)

This method is applicable for the determination of yaw angle, pitch angle, axial velocity 

and the volumetric flow rate of a gas stream in a stack or duct using a three-dimensional (3-D) 

probe. This method may be used only when the average stack or duct gas velocity is greater 

than or equal to 20 ft/sec. When the above condition cannot be met, alternative procedures, 
Dal Tile, Inc. – El Paso, TX Project Nos. 210268 / 211169 

Page 21 of 30

approved by the Administrator, U.S. Environmental Protection Agency, shall be used to make 

accurate flow rate determinations. 

A 3-D probe is used to determine the velocity pressure and the yaw and pitch angles of 

the flow velocity vector in a stack or duct. The method determines the yaw angle directly by 

rotating the probe to null the pressure across a pair of symmetrically placed ports on the probe 

head. The pitch angle is calculated using probe-specific calibration curves. From these values 

and a determination of the stack gas density, the average axial velocity of the stack gas is 

calculated. The average gas volumetric flow rate in the stack or duct is then determined from 

the average axial velocity. All test data, worksheets, and spreadsheets presenting the 

calculations are included in Appendices A and I. Calibration procedures for the velocity 

equipment are located in Section 6.0 of this report 

4.4 US EPA REFERENCE TEST METHOD 3 - DRY GAS MOLECULAR WEIGHT-CARBON 

 DIOXIDE (Spray Dryer SD-1) 

Dry Gas molecular weight (carbon dioxide) was determined using US EPA Reference 

Test Method 3 (Fyrite Method). A sample of the flue gas was extracted from the gas stream 

during each test. These samples were analyzed with a Fyrite gas analyzer. The molecular 

weight of the gas was calculated using the moisture, oxygen and carbon dioxide content, and 

the measured stack gas temperature. 

4.5 US EPA REFERENCE TEST METHOD 3A - MOLECULAR WEIGHT .DETERMINATION 

 INSTRUMENTAL ANALYSIS- OXYGEN/CARBON DIOXIDE 

 (Bisque and Glost Kilns, Tile Dryer No. 5) 

The oxygen/carbon dioxide concentration was determined using US EPA Reference 

Test Method 3A. A sample of the flue gas was extracted from the gas stream during each test. 

Moisture was removed from the sample and the dry sample was then analyzed with an 

instrumental gas analyzer. The molecular weight of the gas was calculated using the moisture, 

oxygen and carbon dioxide content and the measured stack gas temperature. 

4.6 US EPA REFERENCE TEST METHOD 4 - MOISTURE CONTENT 

The moisture content used for calculating the gas stream flow rate was determined by 

measuring the moisture in a series of glass impingers and silica gel impinger gravimetrically with

Page 22 of 30

an analytical balance with a tolerance of 0.1 g. The volume of gas drawn was corrected to dry 

standard conditions. The dry gas meter and thermocouple calibration forms are contained in 

Appendix I. 

4.7 US EPA REFERENCE TEST METHOD 23 - DIOXIN-FURAN DETERMINATION 

This method is applicable to the determination of polychlorinated dibenzo-p-dioxins 

(PCDD's) and polychlorinated dibenzofurans (PCDF's) from stationary sources. A sample is 

withdrawn from the gas stream isokinetically and collected in the sample probe, on a glass fiber 

filter, and on a packed column of adsorbent material. The sample cannot be separated into a 

particle vapor fraction. The PCDD's and PCDF's are extracted from the sample, separated by 

high resolution gas chromatography, and measured by high resolution mass spectrometry. 

4.8 US EPA REFERENCE TEST METHOD 5 WITH METHOD 29 – PARTICULATE AND 

METALS DETERMINATION 

 The particulate/multiple metals sample train consisted of a heated stainless steel sample 

probe with a glass liner equipped with an S-type pitot tube and thermocouple. The probe was 

attached to a sample module consisting of a heated filter compartment, which houses the in-line 

filter holder equipped with a pre-weighed quartz filter for the collection of the particulate, and a 

series of glass impingers to collect metals and determine moisture. The sample module was 

connected to a control module by means of an umbilical cord. The control module consisted of a 

dry gas meter, calibrated orifice, leak free pump, two inclined manometers, and temperature 

controllers for the heated filter compartment, the probe, and a thermocouple indicator to monitor 

the required temperatures during the testing. 

 Gas samples were collected as follows: the sample gas was drawn through the sampling 

probe isokinetically and passed through a 3-inch quartz filter on to which particulate matter was 

deposited. The sample gas was then passed through a series of ice-cooled impingers. The first 

and second impingers contained exactly 100 ml each of an absorbing solution (5% HNO3 10% 

H2O2). The third impinger was empty. The fourth and fifth impingers contained exactly 100 ml 

each of acidic KMnO4 absorbing solution. The sixth impinger contained exactly 250 g of silica 

gel, which absorbs any remaining moisture. These impingers were placed in an ice-bath to 

maintain a maximum exit temperature of 68o

 F. The sample gas then passed through a vacuum 

pump followed by a dry gas meter. The dry gas meter integrated the sample gas flow 
Dal Tile, Inc. – El Paso, TX Project Nos. 210268 / 211169 

Page 23 of 30

throughout the duration of the test. A calibrated orifice attached to the outlet of the dry gas 

meter provided real time flow rate data. 

 A representative gas sample was acquired by sampling for equal periods of time at the 

centroid of a number of equal area regions in the exhaust stack. The sampling rate was 

adjusted at each test point maintaining an isokinetic sampling condition. 

 After the sampling was complete, the filter was removed and placed in a storage 

container. The nozzle, probe liner, and inlet side of the filter holder were quantitatively washed 

with exactly 100 ml of reagent grade acetone and stored in a marked and sealed container. The 

nozzle, probe liner, and inlet side of the filter holder were rinsed again with 0.1N HNO3 and 

placed into another marked and sealed container. The nozzle and probe liner were then rinsed 

with DI water and followed by another acetone rinse. These rinses were not retained and were 

a QA/QC step to ensure clean glassware prior to starting another run. The liquids from the first 

and second impingers were weighed and added to a third marked and sealed container. The 

back half of the filter holder and these two impingers were rinsed with exactly 100 ml of 0.1N 

HNO3 and the rinses were added to the same container. The contents of the third impinger were 

weighed and then rinsed with exactly 100 ml of 0.1N HNO3 and the rinses were placed in a 

fourth marked and sealed container. The liquids from the fourth and fifth impingers were 

weighed and added to a fifth marked and sealed container. These impingers were first rinsed 

with exactly 100 ml of fresh KMnO4, and then exactly 100 ml of distilled water and the rinses 

were added to the sample container. All the samples were transferred to our laboratory for 

particulate determination and shipment to ALS Laboratory Group for metals analysis. The fourth 

and fifth impingers were then rinsed with a total of 25ml of 8N HCI; this was added to 200ml of 

DI water in a sixth marked container and sealed. The sixth impinger was weighed to determine 

moisture catch of the silica gel.

5.0 QA / QC PROCEDURES 

Specific Quality Assurance / Quality Control (QA / QC) procedures were adhered to 

during this test project to provide valid and scientifically defensible data. For any environmental 

field and laboratory measurement, a degree of uncertainty exists in the data due to inherent 

limitations of the measurement systems employed. Entec Services, Inc. objective of the QA / 

QC program is to produce data of known precision, accuracy, representation, completeness, 

and comparability. Special Entec-designed QA/QC checklists are contained in Appendix F. 

For purposes of the ICR, EPA requested that non-detects are to be reported at the 

detection limit for all compounds. This is critical in the D/F results due to calculation of the total 

target analytes as dibenzo-p-dioxins and dibenzofurans. When specific congeners were not 

detected, the summations included detection limits. 

6.0 CALIBRATION PROCEDURES 

 All of the emission testing equipment used was calibrated according to the procedures 

outlined in the EPA 40 CFR Part 60 Appendix “A” and the Quality Assurance Handbook for Air 

Pollution Measurement Systems, Volume III, EPA-600/4-77-027b. Complete calibration records 

are located in the appendix of this report.

Guideline Document

(This is a draft revision to the guideline document GD-008. The alternative testing procedures and

acceptance criteria in the guideline are based on general gas flow theories and practices and are

supported by little real field experience. The EMC requests your review and comment on the

procedures those involving sampling directly in areas of nonaxial flow. Of particular interest would be

results of tests for which these or similar procedures were applied and that we could use to verify or

modify the guideline. Please, e-mail your comments to westlin.peter@epa.gov.)

Particulate Emissions Sampling in Cyclonic Flow

Summary

Particulate emissions sampling in stacks or ducts with cyclonic or other nonaxial flow patterns presents

significant problems in obtaining representative measurements of concentrations and flow rates. Sections 2.4

and 2.5 of Method 1 (40 CFR part 60, appendix A) describe procedures and criteria for verifying the absence

of cyclonic or other nonaxial flow patterns (i.e., not parallel to the stack or duct axis). The purpose of this

guideline is to provide options to consider when the angular or cyclonic flow conditions exceed acceptable

limits as defined in Method 1. Following are three options and detailed recommendations for addressing the

measurement of particulate emissions when cyclonic or nonparallel flow patterns exist. We intend that you

prioritize these options in the order that they are presented; that is, attempting to sample directly in conditions

of cyclonic or nonaxial flow should be the last resort. 

Recommendations

1. Find another sampling location.

 

In many situations, you may find a sampling location downstream or upstream of the original location that

exhibits less cyclonic or nonaxial flow tendencies. For example, moving from a duct immediately

downstream of the exit of a venturi scrubber with a cyclonic demister to a location multiple equivalent

diameters downstream of the duct-stack intersection can often solve a cyclonic flow situation. You may incur

extra cost in such a move (e.g., new ports and sampling platforms); however, this option is often less costly or

disruptive to the process operation and produces more reliable emissions measurement data than the other

options described below.

2. Install flow straightening vanes upstream of the sampling location.

You may use flow straightening vanes, such as are described in Figure 5D-1 of Method 5D (40 CFR part 60,

appendix A). Note that the criteria for locating the measurement site downstream of the straightening vanes

are based on the average equivalent diameter of the straightening vane openings rather than the stack diameter

(section 4.1.1, Method 5D).

Also note that straightening vanes may disrupt the process and may affect control efficiency by creating a

back pressure that might change flow characteristics upstream of the vanes. You may need to explore other

means sufficient to straighten gas flow, such as addition of stack extensions tangential to the stack axis, that

have less effect on the process or control device operations. In any case, you must coordinate use of any flow

disturbance alternative with the plant engineer.

3. Apply a modified sampling procedure.

We recommend the following procedures for sampling only when other options as described in 1 and 2 above

are not available. We previously published guidance (GD-008) for applying alternative procedures for

collecting representative particulate matter samples from areas with nonaxial flow. Among the methods

recommended were the alignment method and the time-weighted alignment method. With the publication of

new EPA Methods 2F and 2G (40 CFR part 60, appendix A) and further review of the principles involved in

such testing, we recommend a revision to those procedures for testing in locations with cyclonic flow. The

revised procedures involve aligning the sampling nozzle with the stack or duct axis for nonaxial flow angles

up to 50°. For flow angles greater than 50°, you should apply a flow alignment method in which you align

the sampling nozzle in the direction of the flow (yaw) angle and you adjust the sampling rate or sampling time

per point appropriately. Note that a test run may involve different procedures for sampling points with flow

angles both greater than and less than 50°.

Note that applying such sampling procedures as an alternative to those specified in a regulation or an

operating permit requires approval by the Administrator prior to conducting the test (see sections 60.8(b),

61.13(h), or 63.7(f) of 40 CFR parts 60, 61, or 63, respectively). Note also that the complexities and special

techniques associated with these alternative procedures are such that only experienced and well-equipped field

staff should attempt this approach.

The modified sampling procedures are as follows:

a. Prior to each test run, conduct a velocity traverse of the stack to establish the angle(s) of flow at each

sampling point using procedures as described in Method 2F, section 8, or Method 2G, section 8. Using 

the yaw and pitch angles, if available, as measured with either Method 2F or 2G, calculate the resultant

angle at each sampling point using equation 1-2 of Method 1. Calculate the axial velocity at each

sampling point using equation 2F-8 or 2G-6. Use pitot equipment for these measurements that satisfies

the QA/QC requirements of sections 6 and 10 of Method 2F or sections 6 and 10 of Method 2G, as

appropriate.

For sampling points with nonaxial resultant angles up to 50°:

b. For each test run following the velocity traverse, conduct the particulate sampling at each sample point

with the nozzle axis aligned parallel to the stack or duct axis. Either remove the pitot from the sampling

probe or ensure that the impact pressure opening plane of the pitot is at least two nozzle diameters

downstream of the sampling nozzle opening. Collect the sample at each point isokinetically relative to

the axial velocity, va, calculated for that sample point during the pre-run velocity traverse (i.e., do not use

the velocity values indicated by the pitot, if attached during the test run). One approach for calculating

isokinetic sampling rates is to substitute an adjusted nozzle area for each traverse point in determining the

sampling rate using the nomograph referenced in Method 5 (e.g., APTD-0576), or other isokinetic

equation procedure (e.g., computer program). Calculate an adjusted nozzle area, Ana, for each sample

point as follows:

A A R na n = ( cos i)

where:

An is the measured area of the nozzle

Ri is the resultant angle of flow at each sampling point.

For sampling points with nonaxial resultant angles 50° and higher:

c. For each test run following the velocity traverse, conduct the sampling isokinetically at each sampling

point rotating the sampling nozzle to point into the gas flow (i.e., parallel to the measured yaw angle) and

using the velocity pressure values in the direction of flow (i.e., yaw angle values) determined during the

pre-run velocity traverse. 

For all test runs:

d. For each test run, conduct a post-run velocity traverse in the same manner as the pre-run velocity traverse

as described in step 3.a. above to verify that the average axial stack or duct velocity remains within 10

percent of the pre-test run value. If the post-test and pre-test values do not agree within 10 percent for

any of the three or more required test runs, conduct an additional test run to replace that test run. You

may use a post-test run velocity traverse as the pre-test run velocity traverse for the next test run.

e. Calculate the isokinetic variation at each sampling point using equation 5-8 of Method 5 based on the

average of the results of the pre-test run and post-test run velocity traverses. Isokinetic variations should

be within the specification found in section 6.12 of Method 5. Follow the guidelines in section 6.12 of

Method 5 for repeating test runs for which you do not meet the isokinetic acceptability criteria.

f. Submit the results for all of the test runs to the responsible regulatory official including the pre-test run

and post-test run velocities for each sampling point, the average axial the emissions data for all of test

runs, and the results of the isokinetic variations calculations. Identify any results outside of the specified

acceptable ranges and any other conditions that might affect conclusions regarding the test results (e.g.,

process conditions, margin of compliance).

correct? My understanding is that we just run each point at 10 minutes for this test.

Troy:

Thanks for your note.  I am afraid we did not communicate quite clearly.

When I said not to apply the Texas cyclonic flow method for traverse points with nonaxial

resultant angles of 50 degrees or greater, I meant that you should apply EPA GD‐008r

(http://www.epa.gov/ttn/emc/guidlnd/gd‐008r.pdf) for all traverse points including those with

resultant angles greater than 50 degrees.

Specifically, you should apply section 3 of the guideline document (see

Dal Tile, Inc. 

El Paso, Texas

Project Numbers 210268 / 211169 ICR Tile MACT Testing Report Appendix Page 269 of 273
3

below) but not adjusting the procedure as described in section c.  I understand that you

found only a very few points with resultant angles greater that 50 degrees and none above

about 55 degrees.

I hope that this clarifies the procedure that I intended to approve for your use at this

site.  Please call me if you have any further questions.

Peter

(The procedure extracted from GD‐008r)

3. Apply a modified sampling procedure.

We recommend the following procedures for sampling only when other options as described in 1

and 2 above are not available. We previously published  guidance (GD‐008) for applying

alternative procedures for collecting representative particulate matter samples from areas

with nonaxial flow. Among the methods recommended were the alignment method and the time‐

weighted alignment method. With the publication of new EPA Methods 2F and 2G (40 CFR part 60,

appendix A) and further review of the principles involved in such testing, we recommend a

revision to those procedures for testing in locations with cyclonic flow. The revised

procedures involve aligning the sampling nozzle with the stack or duct axis for nonaxial flow

angles up to 50°. For flow angles greater than 50°, you should apply a flow alignment method

in which you align the sampling nozzle in the direction of the flow (yaw) angle and you

adjust the sampling rate or sampling time per point appropriately. Note that a test run may

involve different procedures for sampling points with flow angles both greater than and less

than 50°.

Note that applying such sampling procedures as an alternative to those specified in a

regulation or an operating permit requires approval by the Administrator prior to conducting

the test (see sections 60.8(b), 61.13(h), or 63.7(f) of 40 CFR parts 60, 61, or 63,

respectively). Note also that the complexities and special techniques associated with these

alternative procedures are such that only experienced and well‐equipped field staff should

attempt this approach.

The modified sampling procedures are as follows:

a. Prior to each test run, conduct a velocity traverse of the stack to establish the angle(s)

of flow at each sampling point using procedures as described in Method 2F, section 8, or

Method 2G, section 8. Using the yaw and pitch angles, if available, as measured with either

Method 2F or 2G, calculate the resultant angle at each sampling point using equation

1‐2 of Method 1. Calculate the axial velocity at each sampling point using equation 2F‐8 or

2G‐6. Use Pitot equipment for these measurements that satisfies the QA/QC requirements of

sections 6 and 10 of Method 2F or sections 6 and 10 of Method 2G, as appropriate.

For sampling points with nonaxial resultant angles up to 50°:

b. For each test run following the velocity traverse, conduct the particulate sampling at

each sample point with the nozzle axis aligned parallel to the stack or duct axis. Either

remove the Pitot from the sampling probe or ensure that the impact pressure opening plane of

the Pitot is at least two nozzle diameters downstream of the sampling nozzle opening. Collect

the sample at each point isokinetically relative to the axial velocity, va, calculated for

that sample point during the pre‐run velocity traverse (i.e., do not use the velocity values

indicated by the Pitot, if attached during the test run). One approach for calculating

isokinetic sampling rates is to substitute an adjusted nozzle area for each traverse point in

determining the sampling rate using the nomograph referenced in Method 5 (e.g., APTD‐0576),

or other isokinetic equation procedure (e.g., computer program). Calculate an adjusted nozzle

area, A na, for each sample point as follows:

Ri is the resultant angle of flow at each sampling point.

For sampling points with nonaxial resultant angles 50° and higher:

c. For each test run following the velocity traverse, conduct the sampling isokinetically at

each sampling point rotating the sampling nozzle to point into the gas flow (i.e., parallel

to the measured yaw

angle) and using the velocity pressure values in the direction of flow (i.e., yaw angle

values) determined during the pre‐run velocity traverse.

For all test runs:

d. For each test run, conduct a post‐run velocity traverse in the same manner as the pre‐run

velocity traverse as described in step 3.a. above to verify that the average axial stack or

duct velocity remains within 10 percent of the pre‐test run value. If the post‐test and pre‐

test values do not agree within 10 percent for any of the three or more required test runs,

conduct an additional test run to replace that test run. You may use a post‐test run velocity

traverse as the pre‐test run velocity traverse for the next test run.

e. Calculate the isokinetic variation at each sampling point using equation 5‐8 of Method 5

based on the average of the results of the pre‐test run and post‐test run velocity traverses.

Isokinetic variations should be within the specification found in section 6.12 of Method 5.

Follow the guidelines in section 6.12 of Method 5 for repeating test runs for which you do

not meet the isokinetic acceptability criteria.

f. Submit the results for all of the test runs to the responsible regulatory official

including the pre‐test run and post‐test run velocities for each sampling point, the average

axial the emissions data for all of test runs, and the results of the isokinetic variations

calculations.

Identify any results outside of the specified acceptable ranges and any other conditions that

might affect conclusions regarding the test results (e.g., process conditions, margin of

compliance).

Peter,

As a follow up to our conversation on April 25, 2011, I am just confirming your direction in

the testing we are doing at the cyclonic source in El Paso, TX. We will not use Texas

Cyclonic method, nor the EPA Guidance Document, but we will perform this testing as a

“normal”

Method 5 type test. The Pitot will be maintained perpendicular to the stack wall, and no

adjustment will be made to the dwell time or the angles. We will calculate the isokinetics

per regular method 5 type calculations, perpendicular to the stack walls.

Please confirm that I have gotten this direction correct, or correct me if I have made any

errors.
