1.0 Introduction E. Roberts Alley & Associates,

Inc. (ERA&A)

was retained by General Shale Brick, Inc. (General Shale) to conduct emission testing at Plant 36 located in Blue Ridge, Virginia.

Testing was conducted

on the inlet and outlet of the Unit #6 absorber to demonstrate

compliance

with the hydrogen

chloride (HC1) and hydrogen

fluoride (HF) reduction efficiency (RE) requirements

listed in the Virginia Department

of Environmental

Quality (DEQ) Permit Registration No. 20447, conditions

18 and 17. Previous pertbrmance

testing for sulfur dioxide, HC1, HF and visible emissions
was conducted

in November

2006 and in March 2007 for HCI and HF. ERA&A personnel

conducted

the emission testing while General Shale provided all process operating

and control system data to support the testing results.
1.1 Facility and Source Descriptions General Shale's facility manufactures

brick exterior building material.

Shale and clay are mined, crushed and sent tlkrough a screening process prior to brick forming by extrusion.

Once the brick is extruded,

it is dried and fired in a tunnel kiln at approximately

2,000 °F. The facility operates two kilns (A & B) with a common exhatist. After being fired, the brick is cooled, packaged

and shipped to various locations.
The interkiln dryer/kiln

emissions

are controlled

with an ohhnann type dry lime absorber (Unit #6). The exhaust stack is located outside the kiln building on the east side.
1.2 Project Team The emission testing was conducted

by Mr. Stacey Cunningham

(Team Leader), Mr. Kem•y Boyd and Mr. Matt Hamilton. Mr. Chris LeMay served as ERA&A's

Project Manager while Ms. Brandy Hughes served as the Report Coordinator. Ms. Martha West of General Shale served as ERA&A's

tec|mical contact and coordinated

the testing with facility operations.

Mr. William Klepper from DEQ was present during the onsite testing.

1.3 Laboratory HC1 and HF analyses were performed

by Maxxam Analytical

Inc. of Burlington,

Ontario, Canada.
1.4 Protocol/Method

Deviations The were no deviations

fi-om the Stack Test Protocol form submitted

to DEQ on July 9, 2007 or U.S. EPA Reference Test Methods.

compliance

testing on Unit #6 at the Blue Ridge, Virginia facility. Testing was conducted

on August 22, 2007 and consisted of tlu-ee (3) 60-minute

test runs on the inlet and outlet of the absorber.
Table 2-1 provides a summary of the emission testing results. Any difference

between the summary results listed in the following

3.0 Testing Methodology The emission testing program was conducted

in accordance

with the U.S. EPA Reference

Test Methods listed in Table 3-l. Method descriptions

are provided

below, while quality assurance/quality

control data is provided

in Appendix D.

3.1 Methods

1 & 2 Volumetric

Flow Rate The sampling

location and number of traverse (sampling)

points •vere selected in strict accordance

with EPA Reference Method 1. A full velocity traverse (EPA Reference

Method 2) was conducted

during each test run to determine the average stack gas velocity pressure, static pressure and temperature.

The velocity and static pressure measurement system consisted of an S-type pitot tube and inclined manometer

while the stack gas temperature

was measnred with a K-type thermocouple

and pyrometer.

3.2 Method 3 Oxygen/Carbon

Dioxide The oxygen and carbon dioxide concentrations

were determined

in accordance

with EPA Reference

Method 3. One (1) integrated

Tedlar bag sample was collected during each test run. The bag sample was analyzed on site with a Eyrite 0•_/C02 analyzer.

The Fyrite solutions were verified before and after testing by condncting

a calibration check with EPA Protocol

O2/CO2 gas. The remaining

stack gas constituent

was assumed to be nitrogen tbr the stack gas molecular

weight determination.

3.3 Method 4 Moisture

Content The gas moisture contents were determined

in accordance

with EPA Reference

Method 4. The gas conditioning trains consisted

of a series of chilled impingers.

Each impmger was pre and post-weighed

on the same analytical balance to determine

the amount of moisture condensed

during each test run.
3.4 Method 26A Hydrogen

Chloride/Hydrogen

Flnoride The hydrogen

chloride and hydrogen

fluoride concentrations

were determined

in accordance

with EPA Refi•rence Method 26A. The complete sampling system consisted of a glass nozzle, heated glass-lined

probe, hea•ed Teflon filter, gas conditioning

train, pnmp and calibrated

d•T gas meter. The gas conditioning

train consisted of five (5) impingers contained in an ice/water bath. The first and second impingers

contamecl

100 nit. of 0.1 N 11>504. the third and lburth contained 100 mL of 0.1 N NaOH and the fifth contained

approximately

200 grams of silica gel.

of each test run, the sampling train was leak checked at a vacuum pressure greater than or equal to the highest vacuum pressure observed

during the run. The impingers

were weighed on an electronic balance to determine

the amount of moisture gained. The contents of the first two (2) impingers

were recovered

in Sample Container

1. All connecting

glassware,

including

the back half of the filter holder, was rinsed with DI water and these rinses added to Sample Container

1. The contents of impingers

three (3) and four (4) were recovered

in Sample Container

2. All comaecting

glassware,

from the inlet of the third impinger

to the outlet of the fourth impinger, was rinsed with DI water and these rinses added to Sample Container

2. Container

2 •vill be held unless fi,•rther analysis is requested.

All containers

were sealed, labeled, and liquid levels marked for transport to Maxxam Analytics

Inc. in Burlington, Ontario, Canada. The samples were analyzed by high performance

liquid chromatography

(HPLC).
