METHODS This section describes

the sampling

strategy, sampling

and analytical

methods,

and quality assurance/quality control procedures

implemented

during this project.
3.1 Sampling

Strategy The sampling

and analytical

procedures

used during this test program

were those established

by the US EPA and NC DENR.

Sampling

runs were conducted

in triplicate

to validate the sampling.

Tests were conducted during normal operating

conditions.
3.2 Sampling

and Analytical

Procedures The US EPA methods

used in this sampling

program were Method 1 for the location of sampling

ports and points, and determination

of cyclonic flow, Method 2 for volumetric

flow rate determination,

Method 3 for the determination

of dry molecular

weight of the stack gas, Method 4 for the determination

of moisture

in the stack gas, Method 5 for the determination

of particulate

matter, Method 9 for determination

of visible emissions and Method 26A for the determination

of hydrogen

chloride and hydrogen

fluoride.

A sampling and analysis

synopsis

for these methods

is discussed

briefly in the following

subsections.

These test methods are available

in the Code of Federal Regulations

Volume 40, Part 60 or by request from Trigon.
3.2.1 Sampling

Ports, Traverse

Points and Cyclonic

Flow Determination The sampling

locations

were prepared

according

to the criteria in Method 1. The duct diameters

upstream and downstream

from the sampling

ports were determined

prior to sampling.

The number of traverse points

were chosen with respect to sampling

port location.

For particulate

traverses

Method 1 specifies

a minimum of 8 traverse points for sampling

ports located >8/>2 downstream/upstream stack diameters

from flow disturbances and 24 traverse points when located >2/>0.5.

The amount of cyclonic

flow was determined according to the criteria detailed in Method 1.
3.2.2 Stack Ga's Velocity

and Volumetric

Flow Rate Determination Method 2 is used for determining

the average gas velocity in a stack from measurements

of gas density and the average velocity head with a Type S (Stausscheibe

or reverse type) pitot tube. This method is applicable for quantifying

gas flows which meet the criteria of Method 1.

In principle,

measurements

of velocity head and temperature

are performed

at the traverse points specified by Method

1. A properly

scaled differential

pressure

gauge was selected for the range of Ap values encountered during the traverse.

A 0 10 inches of water inclined manometer

was used. as the differential pressure gauge. During this project, the sampling

location met the criteria detailed in Method 1. Gas stream density was determined by Method 3. Moisture

determination

was performed

by Method 4. The principal

components of the gas velocity measurement

system were sequentially:

• A calibrated

stainless steel Type S pitot tube and Type K thermoeouple;

• Leak'-free

interface

tubing betwee.n pitot tube and differential

pressure gauge;

• A 0 to I 0 inch inclined manometer;

and

• An NIST traceable

pyrometer.
The apparatus

was set-up according

to manufacturer

and reference

method recommendations.

Pre-test and post-test leak checks were conducted

using procedures

outlined in Method 2, Section 3.1. Velocity head and temperature measurements

were performed

at the traverse points specified

by Method 1. The atmospheric and static pressure of the stack was also determined

for the velocity head readings.

The volumetric

flow rate calculations

used were those specified

in Method 2, Section 5. A more comprehensive

explanation

of the reference

method is detailed

3.2.3 Dry Molecular

Weight

Determination Method 3 is applicable

for determining

carbon dioxide and oxygen concentrations

and dry molecular

weight of a sample from a gas stream of a fossil-fuel

combustion

process.

This method may also be applicable

to other processes

where it has been determined

that compounds

other than carbon dioxide, oxygen, carbon monoxide, and nitrogen are not present in concentrations

sufficient

to affect the results.

In principle

a gas sample was withdrawn

from the emission

source by multi-point,

integrated

sampling.

The collected sample was then analyzed

for percent carbon dioxide,

percent oxygen,

and percent carbon monoxide. The dry molecular

weight determination

was performed

3.2.4 Moisture

Determination Method 4 involves

the determination

of stack gas moisture.

The moisture

content is used to correct the emission concentration

or mass emission

rate to a dry basis. EPA Method 4 and Field Procedure

4 of the QA Handbook

was used to measure

stack gas moisture

content.

Field Procedure

4 provides

detailed information on the application

of Method 4.
The moisture

content for emission

rate calculations

was determined

in conjunction

with the Method 26A isokinetic sampling

train. The reference

method involves

the withdrawal

of gaseous pollutants

from the emission source at an isokinetic

rate using a Method 26A sampling

system. The sampling

and analytical procedure for reference

Method 4 will be discussed

in detail in Section 3.2.6 with the isokinetic

sampling procedures.

3.2.5 Visual Determination

of Opacity Method 9 involves the determination

of stack plume opacity by an individual

properly trained and certified in performing

visual emission

observations.

of opacity.

Instantaneous

readings are made every 15 seconds and the value recorded

on the appropriate

form. When making visual emission

determinations

the observer

must apply specific criteria to the source layout in order to eliminate

any bias which exerts a significant

influence upon plume appearance.

These variables

include:

• Angle of the observer with respect to the plume;

• Angle of the observer with respect to the sun;

• Point of observation

of attached and detached

steam plume and;

• Angle of the observer

with respect to a plume emitted from a rectangular

stack with a large length to width ratio.

A set of opacity data reduction

calculations

is def'med as the average of any 24 consecutive

15 second observations. Sets need not be consecutive

in time and in no case shall two sets overlap.

The highestsixminute average of a 60 minute test is recorded

on the field data sheet.

3.2.6 Particulate,

Hydrogen

Chloride

and Hydrogen

Fluoride

Sampling

and Analysis Testing for particulate

matter, hydrogen

chloride,

and hydrogen

fluoride was performed

according

to EPA Method 26A. Gaseous

and particulate

pollutants

were withdrawn

isokinetically

from the emission

source and collected

in a multi-component

sampling

train. In principle,

particulate

matter that was condensed

at or above the filtration

temperature

of approximately

250 degrees Fahrenheit

was collected

on a tared quartz filter. The gaseous components

were then bubbled through a measured

volume of 0.1N sulfuric acid and 0.1N sodium hydroxide

to determine

the moisture

along with the hydrogen

chloride and hydrogen

fluoride content of the emission

source. The principal

components

of the sampling

system were sequentially:

• A borosilicate

glass sample nozzle and probe liner;

• A heated (248°F +25°F) probe and filter assembly

with quartz media filter;

• An impinger

train consisting

of five sequential

impingers.

Impingers

one and two containing 100 ml each of an absorbing

solution consisting

of dilute sulfuric acid (0.1N H2SO4).

The third impinger was left empty. Impinger

four contained

100 ml of dilute sodium hydroxide

(0.1N NaOH) followed

by a final impinger

containing

200 grams of silica gel; and

• A metering

system capable of maintaining

an isokinetic

sampling

rate and accurately determining the sample volume according

to those specifications

in APTD-0581.

Source Sampling, Triangle Brick Company April 22, 2005 Brick Kiln Exhaust, Wadesboro,

North Carolina Trigon Project No. 046-05-011 Sample clean up began immediately

after the test run. Hydrogen

chloride and hydrogen

fluoride were collected in the 0.1N sulfuric acid solution in impingers

one and two. The liquid in these, impingers

was measured to the nearest milliliter

and recorded

in order to determine

the moisture

content.

The collected sample was placed in a high-density

polyethylene

(HDPE) storage container

along with the deionized

water rinse of impingers

one and two and connecting

glassware.

The container

was sealed and the liquid level

was marked.

The 0.1N sodium hydroxide

solution in impingers

three and four was measured

to further determine the moisture

content and stored at Trigon for potential

further analysis of halogens.

The moisture collected by the silica gel in the fifth impinger

was determined

to the nearest 0.1 gram. Collected condensate measurements

were recorded

on the "moisture

determination

and sample recovery

data analysis" form. The samples were then transported

to Enthalpy

Analytical,

Inc., Durham,

North Carolina

with chain of custody

documentation

where they were analyzed

by ion chromatography.

Chain of custody documentation, quantitation

data, and sample specific narratives

are provided

in Appendix

C. The filter, which collected

the sample, was carefully

removed

from the Teflon filter support and sealed in a petri dish. The nozzle, probe liner, and front filter-half

of the filter assembly

were rinsed with acetone into a glass storage container,

which was sealed, and the liquid level marked.

The sample containers were transported

to Trigon's Air Quality Laboratory

in Charlotte,

North Carolina

for particulate matter analysis.The particulate

matter analyses began by transferring

the acetone samples to tared beakers.

These samples were taken to dryness, and then placed in a desiccator

along with the filters for an initial drying period of 24 hours. The particulate

mass was determined

gravimetrically.

The tare weights of the filters and beakers were subtracted

from the final weights to determine

the gross particulate

weight.
3.2.7 Location

of Sampling

Ports and Points Method 1 sampling

criteria was maintained.

The stack cross section was divided into 12 equal areas. The ports were labeled A and B. During the test runs each point was sampled for 7.5 minutes which yielded a total test time of 90 minutes.

The dimensions

of the stack and the location of the sampling

ports and points

are detailed in Figure 2.

Assurance

and Quality

Control Trigon Engineering

Consultants,

Inc., has established

quality assurance

and quality control (QA/QC) guidelines for providing

quality sampling

and analytical

data from source tests. These QA/QC procedures were implemented

to ensure the acceptability

and reliability

of the data generated.

In summary,

an appropriate

degree of data quality was maintained

throughout

this project. Leak checks and isokinetic QA criteria were met. The sampling

trains were leak checked prior to and immediately

after sampling. Leak rates for the isokinetic

sampling

trains were less than the maxmaum

criterion of 0.02 cubic feet per minute.

The sampling

rates were also within the 100% +10% criterion

established

for isokinetic sampling. Quality control procedures
