1.0 INTRODUCTION 

Environmental Source Samplers, Inc. (ESS) conducted air emissions sampling at Pine Hall Brick's 

Madison, North Carolina plant. Sampling was conducted on the DLA (Control Device ID No. 4ESDLA) Inlet and Outlet stacks associated with the Brick Kiln (for sources Kiln No. 4ES-LKD4.1 and 

Kiln 4ES-LKD4.2). 

Sampling was performed for particulate (PM), visible emissions (VE), hydrogen chloride (HCl), and 

hydrogen fluoride (HF). U.S. Environmental Protection Agency (EPA) Method 5 was utilized to 

perform the PM sampling (conducted only at the outlet stack). EPA Method 9 was conducted 

pursuant to the stipulated methodology. Method 26 was used to conduct the HCl and HF emissions 

testing at the inlet and outlet sampling locations. EPA Methods 1-4 were used in support of the 

above testing procedures, as required. All methods appear in 40 CFR 60, Appendix A. A series of 

three (3) 60-minute test runs were performed for each of the aforementioned parameters. 

This sampling was performed to demonstrate compliance, as required in 40 CFR 63, Subpart JJJJJ 

and with the permit requirements imposed by the North Carolina Department of the Environment 

and Natural Resources (NCDENR)- Permit No. 03997Tl8. Personnel present included:

EPA Method 26- HCVHF Emissions 

EPA Method 26 procedures were followed in collecting the acid emission data. Sample test runs 

were 60 minutes in duration, assuring a minimum sample volume of greater than the 3.5 cubic feet. 

I, 2, 3, and 4 were used in support of EPA Method 26 procedures. Flowrate, moisture and 02/C02 

measurements were obtained from the Method 5 test that was conducted simultaneously with the 

M26 sampling. On the inlet side of the DLA, a separate flowrate and 02/C02 measurement was 

conducted. Moisture was conducted in conjunction with the M26 test - on the inlet duct. 

The test probe consisted of a heated glass lined sheath. The filter and probe heat temperatures 

were maintained above 248 degrees F, per Method 26 requirements. A Pallflex TX40Hl45 filter 

was used in conjunction with a teflon filter frit and glass filter assembly. 

The first two (2) impingers' each contained l 0 mls of 0.1 N sulfuric acid. The following two (2) 

impingers each contained l 0 mls of 0.1 N sodium hydroxide. Following each test run, the contents 

of the first/two (2) impingers (container l) were saved along with the wash of the impingers and 

connecting _glassware. 

The samples were delivered to the laboratory for ion chromatography analysis. The samples were 

analyzed on a Hewlett Packard series ll 00 High Performance Liquid Chromatograph using ion 

chromatography. Each sample was analyzed in duplicate. The results were also verified through 

duplicate HPLC analysis.

Environmental Source Samplers, Inc. 
EPA Method 5 - Particulate Emissions 

EPA Method 5 procedures were followed in collecting the particulate emission data. Sample test 

runs were 60 minutes in duration, assuring a minimum sample volume of greater than 40 cubic 

feet. EPA Methods l, 2, 3b, and 4 were used in support of EPA Method 5 procedures. 

The test probe consisted of a heated stainless steel lined sheath, with attached stainless steel 

pi tot tubes and temperature sensor. Per section 4.2 of EPA Method 5, acetone was used to 

rinse the nozzle, probe, and front half of the filter holder. An EPA type glass fiber filter was used 

in the heated filter box. 

The gravimetric analysis of the acetone probe washes and filters was performed in the ESS 

laboratory in accordance with EPA Method 5 section 4.3 procedures. EPA Method 5 procedures 

were also followed, requiring the filter to be oven dried at 220 degrees F. for 2-3 hours, 

desicated for 2 hours and then weighed to a constant weight. The acetone probe wash was 

evaporated at an elevated temperature, but below the boiling point to prevent bumping. The beaker 

was then desiccated for 24 hours prior to weighing to a constant weight.

Field Sampling Operations 

The project supervisor was responsible for ensuring that proper custody and documentation 

procedures were followed for the field sampling and field analytical efforts. He was assisted 

by the stack team assistant. 

The samples were collected, transported, and stored in clean containers which are constructed 

of materials inert to the sample contents. 

All sampling data was recorded on data sheets specific to the test method employed. 

After collection, all samples were maintained in a locked transport box or vehicle. 

· .. Isokinetic Particulate Sampling 

The isokinetic sampling train was visually inspected upon arrival at the test site for potential

damage. Upon assembly of the sampling train components, careful inspections were made of 

the sampling nozzle and pi tot tube tips. A leak check was performed across the entire sampling 

train, as well as across each leg of the pitot tubes. The rnagnehelic pressure gauges were properly 

leveled. The probe was carefully marked with heat resistant marking tape at each of the 

designated sample points. 100 mls of distilled water is placed in each of the first two (2) 

Imptngers. 

During each test run, care was taken to insure that the pi tot tubes remained at the proper angle 

perpendicular to the sample plane. The test port was properly sealed to insure no intrusion of 

ambient air into the sample nozzle. Data was carefully recorded, and the pump was adjusted 

quickly upon moving to each new sample point to maintain an isokinetic sample rate. Data was 

manually recorded at 5.0 minute intervals. Sufficient ice was retained in the impinger train 

to maintain a temperature below 68 degrees F exiting the silica gel impinger. 

At the conclusion of each test run, a leak check was performed across the entire sample train. 

The probe and nozzle were rinsed and brushed with acetone a minimum of six (6) passes. 

The acetone rinse collectiQn bottle was marked, in order that it could be checked upon arrival 

at the ESS laboratory for leakage. The filter holder was removed, plugged, and stored for 

transport back J<o the ESS laboratory. < • .. __ • 

Separate filter· holders were used for each test run to prevent contamination of the filter through 

handling in the field. 

Calibration Procedures 

EPA and DHEC procedures were followed in performing equipment calibrations. Procedures 

outlined in the EPA Quality Assurance Handbook for Air Pollution Measurement Systems, Volume 

III, (EPA/600/R-94/038c) were followed. 

The dry gas meter receives a complete calibration at a minimum of every 6 months. A post test 

calibration is performed after each field use. The post test calibration must be within 5% of the pretest calibration. 

The pi tot tubes receive a complete calibration according top section 4.1 of EPA Method 2 prior to 

and following each field use. Following each field use, the procedures in sections 4.1.6.2.1 -

4.1.6.2.2 are followed. 

A complete calibration is performed on the dry gas, impinger, stack"g<J.S, and probe thermometers 

every 6 months. This calibration is checked after each field use, and' must be within 1.5 percent of 

the reference temperature per section 4.3 of EPA Method 2.
