INTRODUCTION

This report presents the results of filterable particulate matter (PM), hydrogen chloride (HCl), 

hydrogen fluoride (HF), chlorine (Cl2), multiple metals (including Hg) and dioxin/furan (D/F) 

emissions testing performed on the outlet of the dry lime injection fabric filter baghouse on Brick 

Kiln #4, Brick Kiln #5 (at Boral Bricks, Inc Augusta, Georgia facility) and Brick Kiln #6 (at 

Boral Bricks, Inc. East Spencer, North Carolina facility). In addition, one (1) dryer was selected 

from each plant and tested for D/F only.

The following table outlines the methodology utilized.

SOURCE DESCRIPTION

Testing was conducted at the outlet of the dry lime injection fabric filter (CE41) that controls 

acid gas (HCl and HF) and particulate emissions released from the gas-fired brick tunnel kilns. 

The control system utilizes injection of hydrated lime into the brick kiln exhaust stream which 

reacts with HF and HCl to form calcium fluoride and calcium chloride. The spent lime (CaF and 

CaCl) is removed from the exhaust air stream by bagfilters and is transported off site for 

disposal. The baghouse exhaust gas contains un-reacted pollutants and particulate matter.

Testing was also conducted at the outlet of a dryer stack (some dryers have multiple stacks, one 

representative stack was selected for each plant) associated with each plant. “Green” brick are set 

on a kiln car and placed in a holding area where initial drying occurs. From the warming area, 

bricks enter the dryer where the temperature is raised and most of the process water is removed 

before entering the kiln. In the kiln, final evaporation of the process water takes place as well as 

oxidation, vitrification, and the cooling process. All heat used in this process is formed in the 

kiln and waste heat is used for the dryer with no supplementary heat. After exiting the kiln, 

bricks are packaged and stored on site for sale.

The purpose of this test was to satisfy an EPA request for information.

SAMPLING AND ANALYTICAL PROCEDURES

Particulate Matter

Particulate Matter (PM) testing and analysis were performed according to procedures developed 

by the U. S. Environmental Protection Agency (US EPA) and referred to as Method 5. Method 5 

sampling was performed in combination with the Method 26A procedures. Sampling port 

locations and number of test points to be used were determined according to Method 1. 

ATC Laboratory Equipment for Gravimetric Analysis

Laboratory Technician Keith Poole utilized the following equipment in the analysis of US EPA 

method five samples.

1) Precisa 303A Analytical Lab Balance-certification and annual 

maintenance by Precision Weights, Inc. (completed 4/19/2010).

Prior to each use, the balance is calibrated with NIST Traceable weights0.5000, 50.0000, 100.0000, and 200.0000 grams, and

2) a Nalgene® 5317-0180 Dessicator cabinet with indicating desiccant.

ATC’s laboratory environment is maintained at 68 + 10 oF and humidity levels maintained at less 

than 50% with all samples stored in a controlled environment dessicator with the same 

temperature requirements cited above and humidity levels at 15 + 8% RH. 

Prior to the field test, filter media were prepared by sequentially numbering Whatman® 934AH 

3" quartz filters with a non-bleeding marker and oven drying. Duplicate weights were then 

performed on the filters to reach a constant weight. Additionally, sufficient quantities of 

numbered 150ml Griffin beakers were thoroughly washed with warm, soapy water and ovendried. Once cooled, the beakers were also weighed to a constant weight and stored in the 

dessicator cabinet until needed.

After field testing and recovery, each filter was stored individually in petri dishes until 

transferred to the dessicator for a period of no less than twenty-four hours at room temperature 

and constant relative humidity; filters were then weighed to a constant weight (to the nearest 0.1 

mg-weighings over minimum of six hour period).

A blank of the acetone reagent was collected in the field, along with the samples and analyzed 

side by side. An appropriate portion of acetone (density 0.788 mg/l) was evaporated. The 

maximum allowable residue according to US EPA QA/QC documentation is 0.0001% grams. 

The net gain of the acetone blank was applied based upon this and a ratio of the volume of the 

sample to the volume of the blank according to the following equation.

HCl, HF, CL2 Sampling

HCl, HF, and CL2 testing and analysis were performed according to procedures 

developed by the U. S. Environmental Protection Agency (US EPA) and referred to as 

Method 26a and combined with US EPA Method 5 for compliance particulate 

determinations. The impinger contents are as represented in the sketch on the following 

pages. The contents of the impingers in the all-glass sampling train were 0.1 N H2SO4 in 

impingers one and two, 0.1 N NaOH in impingers three and four, and 300 grams of silica 

gel in impinger five. Enthalpy Analytical of Durham, NC performed the HCl, HF, and 

CL2 analyses. The back half of the sampling train (0.1 N NaOH) was analyzed for Cl2. 

Please refer to the lab report for additional details on the HCl, HF, and CL2 analysis.

Multiple Metal Sampling

Multiple metals determinations were conducted according to US EPA Method 29. The 

impinger contents are as represented in the sketch on the following pages (including 

knockout impinger). The nozzle, probe liner and filter holder were all either quartz glass 

or pyrex. A 3" Pallflex 2500QATUUP quartz fiber filter was utilized to filter the 

sampled air. The temperature of the incoming gas was maintained at 250 oF +/- 25 

through the probe and also at the exhaust of the filter. Please refer to the page preceding 

the sketch of the sampling train for an explanation of sample fractions.

All metals train sample recovery was conducted on site. Sample fractions were placed in 

appropriately sized glass amber jars with Teflon lids and sealed and labeled. Samples 

were delivered to First Analytical Labs in Chapel Hill, NC for analysis.

Dioxin/Furan Sampling

Dioxin/Furan determinations were conducted according to US EPA Method 23. The sampling 

train is represented in the sketch below. The nozzle, probe liner and filter holder were all either 

quartz glass or pyrex. A 3" filter (provided by the analytical laboratory) was utilized to filter the 

sampled air. The temperature of the incoming gas was maintained at 250 oF +/- 25 through the 

probe and also at the exhaust of the filter. 

All dioxin/furan train sample recovery was conducted on site. Sample fractions were placed in 

appropriately sized glass amber jars with Teflon lids and sealed and labeled. Samples were 

delivered to Alta Analytical Perspectives, Inc. in Wilmington, NC for analysis.

Quality Assurance Procedures

The following steps were conducted to ensure the accuracy and precision of this test project.

1. All laboratory glassware was cleaned and prepped according to US EPA methodologies 

and ATC SOPs prior to use.

2. All laboratory glassware used for gravimetric determinations were weighed in duplicate 

with agreement required to within a difference of less than 0.0005 grams.

3. All sampling equipment (nozzles, pitot tubes, modules, exit gas thermometers, 

thermocouple bridges, etc) has primary calibrations performed on an annual schedule.

4. All sampling equipment was visually inspected prior to assembly in the shop.

5. Sampling trains were leak checked at a vacuum of no less than 15” Hg prior to the start of 

sampling.

6. At the conclusion of the sampling project, pitot tubes were inspected according to US 

EPA method 2 specifications, thermocouples calibrated, and the sampling module 

calibrated at test ranges.

7. All data that has been entered into an Excel spreadsheet in the field and on pre-printed 

ATC forms was double-checked in the office and reviewed.

8. A draft report was generated and submitted for review.

9. The President (Mr. Bill Kissel ) reviewed and signed this report prior to release.
