in Augusta,

Georgia

was retained

Entec Services,

Inc. to perform emissions testing

on the Kiln DIFF system

(inlet duct and exhaust

stack).

Mr. Tim Draheim, Mr. Jason English,

Mr. Eddie Rudloff,

and Mr. Ryan Harris of Entec Services, Inc. conducted

the testing on Nov. 1 and 2, 2006.

Representing

Boral Brick was Mr. Frank Porter who coordinated

testing with the control room production

activity.
No difficulties

were encountered

in the field collection

or in the laboratory

analysis

of the samples by Entec Services,

Inc personnel. The test summaries

for both plants are on the following

pages with the detailed

analysis for particulate,

hydrogen

chloride

and hydrogen

fluoride

for each run. The total reduction efficiency

has been detailed

for Plant 5 on the emissions

Methods

were followed throughout

the duration

of the field and laboratory

testing. The most current

revision

revised

as of July 1, 2004, of each method

(as described

in the Federal

Register)

was used. Stack Gas Volumetric

Flow The velocity

of the gas stream was determined

according

to EPA Reference

Method

1 and 2 by reading

the instantaneous

velocity

head with an inclined

manometer

at each sampling point with a calibrated

S-type

pitot tube attached

adjacent

to the sample nozzle. 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. The stack was tested previously

for cyclonic

flow according

to EPA Reference

Method 1.Stack Gas Molecular

Weiqht The carbon

dioxide

and oxygen

concentrations

were determined

using EPA Reference 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. Moisture Content The moisture

content

used for calculating

the gas stream

flow rate was determined

by weighing the amount

of condensed

moisture

collected

in the impingers

of the sampling train as described

in EPA Reference

Method

4 at the completion

of each test. The moisture content

will be conducted

in conjunction

with EPA Method

26A. The moisture

collection

system

consists

of a series of impingers.

Ice is placed around the impingers

to maintain

a temperature

<680 F. The outlet temperature

of theimpingers is monitored

and recorded

throughout

the duration

of the testing to verify the temperature is below <680 F. Particulate with Hydrogen

Chloride

and Hydrogen

Fluoride,

(HCI/HF) Preliminary data was used to determine

stack temperature,

pressure,

and range of velocity heads,

moisture

content

and stack gas dry molecular

weight prior to sampling. The meter box was leak checked

from the pump to the orifice.

Initial and final leak checks of the sampling

system

and pitot lines were performed

as outlined

in Method

5 and were recorded

on the data sheets.

The nozzle

(glass with an angle of taper of 30 degrees and of button hook design)

was calibrated

before and after the test using a micrometer and was recorded

on the field data sheets. The sampling

probe was placed at each sampling

point to provide

a total sampling

time of sixty (60) minutes.

The gases were drawn through

a glass nozzle

attached

to a heated glass lined probe.

The probe was maintained

at the proper settings

to obtain
an exit temperature

of greater

than 2480 F during sampling.

The gases then proceeded through borosilicate

glass filter holder,

with a Teflon frit filter support

through

a Teflon filter to remove

particulate

matter.

The filter was maintained

at a temperature

of greater than 248 0 F. These temperatures

were recorded

at each point on the field data sheets. The gases were then scrubbed

through

a series of four pre-weighed

impingers

to capture hydrogen

halides

and halogens

and moisture.

(The optional

first impinger

for a knockout for moisture

was not used.)

The first and second

impingers

contained approximately 100 ml of a 0.1N H2SO,• (acid) solution

and the third and fourth impingers contained approximately

100 ml of a 0.1 N NaOH (alkaline)

solution.

The fifth impinger contained pre weighed

silica gel to remove

any remaining

moisture.

The gases pass through the impinger

series in an ice bath to maintain

a maximum

exit temperature

of 68 0 F. This temperature

was also recorded

on the data sheets.

The clean and cool gases then entered

the meter box where the gas flow and temperature

were measured. After the completion

of the test the sampling

train and the probe nozzle assembly

was transferred to the cleanup

area making

sure no particulate

was lost. The cleanup

data was recorded.The

first and second

impinger

contents

were transferred

to its tared container,

weighed and the rinsing from the glassware

were added to this container.

The third and fourth impinger was transferred

to its respective

tared container,

weighed

and the rinsing from the glassware

was added to this container.

The silica gel from the fifth impinger

was transferred to its respective

tared container

and weighed.

A blank of the sulfuric

acid solution, sodium

hydroxide,

distilled

water and acetone

was taken. These containers
were clearly marked

and transported

to the laboratory

for analysis. Visual Emissions The qualified

observer

stood at a distance

sufficient

to provide

a clear view of the emissions with the sun oriented

in the 140 ° sector to his back.

Consistent

with maintaining the above requirement,

the observer

did, as much as possible,

make his observations from a position

such that his line of vision is approximately

perpendicular to the plume direction.

The observer's

line of sight did not include

more than one plume at a time when multiple

stacks are involved,

and in any case the observer

did make his observations with his line of sight perpendicular

to the longer axis of such a set of multiple stacks (e.g., stub stacks on bag-houses).

The observer

recorded

the name of the plant, emission

location,

facility type, observer's

name and affiliation,

and the date
on a field data sheet.

The time, estimated

distance

to the emission

location, approximate wind direction,

estimated

wind speed,

description

of the sky condition (presence and color of clouds),

and plume background

are recorded

on the field data sheets at the time opacity

readings

are initiated

and completed.

Observations

were made in fifteen-second

intervals

and recorded

in increments

of 5%. The baghouse

was observed for three one hour runs in conjunction

with the Method
