2.0 Process Description

The Guardian facility in Mineral Wells incl udes a refractory-lined electric melt furnace controlled by an externally vented baghouse. Mixed batch is fed to the electric melter furnace and melted to be formed into fiberglass. The emissions test program will evaluate air pollutant emission rates from the single exhaust stack exhaus ting emissions from the electric melt furnace.

## The stack serving the electric melt furnace (AB-005) is round and 29 inches in diameter at the test location. The stack is equi pped with four emissions test ports , each four inches in diameter. Testing was conducted from a stack platform locat ed approximately fifty feet above the plant floor. The Guardian facility in Mineral Wells is located at 7046 State Line Road in Mineral Wells, Mississippi.

2.1 Process Monitoring

During the emissions test program, the elec tric melt furnace was operated under maximum conditions. In addition to total production for e ach test run, process opera ting data recorded (at 15-minute intervals) during the emissions test program included (1) baghouse pressure drop, (2) baghouse operating temperature, and (3) bag leak detector reading. Proc ess production data is available in Appendix B. Control equipment da ta will be available to U.S. EPA on request.

3.0 Sampling and Analytical Methodologies

Sampling and analytical methodologies for the emi ssions test program can be separated into six categories as follows:

(1) Measurement of exhaust gas velocity, mo lecular weight, and moisture content; (2) Measurement of exhaust gas PM and PM 2.5 

## concentrations and emission rates; (3) Measurement of exhaust gas total selected metals concentrations and emission rates; (4) Measurement of exhaust gas Hg concentrations and emission rates; (5) Measurement of exhaust gas hexavalent chro mium concentrations and emission rates; (6) Measurement of exhaust gas HF and HCl concentrations and emission rates;

Descriptions of sampling and analytical methodologies by cate gory are summarized by Sections 3.1 through 3.6, respectively.

3.1 Exhaust Gas Velocity, Molecular Weight, and Moisture Content

Measurement of exhaust gas velocity, molecula r weight, and moisture content was conducted using the following reference test methods codifi ed at Title 40, Part 60, Appendix A of the Code of Federal Regulations (40 CFR 60, Appendix A):

• Method 1 - “Location of the Sampling Site and Sampling Points” • Method 2 - “Determination of Stack Gas Velo city and Volumetric Flowrate” • Method 3A - “Determination of Oxygen and Carbon Dioxide Concentrations in Emissions from Stationary Sources”( Instrumental Analyzer Procedure) • Method 4 - “Determination of Moisture Content in Stack Gases”

These test methods were used to evaluate exha ust gas flowrates either in conjunction with the isokinetic sampling methodologies used to evaluate some pollutant emission rates or as separate, discrete measurements conducted in support of the non-isokinetic sa mpling methodologies.

## Guardian Fiberglass, Inc. BTEC Project No. 10-3990.05 NAIMA/U.S. EPA Emissions Test Report November 12, 2010 3 

## Stack gas velocity traverses we re conducted in accordance with the procedures outlined in Method 1 and Method 2 (see Figure 1 for a traverse location drawing). An S-type pitot tube with a thermocouple assembly, calibrated in accordance with Method 2, Section 4.1.1, was used to measure exhaust gas velocity pressures (using a manometer) and temperatures at each location during testing. The S-type pitot tube dimensions will be within specified limits, therefore, a baseline pitot tube coefficient of 0.84 (dimensionless) will be assigned.

Molecular weight was determined ac cording to USEPA Method 3. The O 2 

## content of the exhaust gas was measured via integrated bag sa mpling followed by Method 3 Orsat gas analysis. A schematic drawing of the sampli ng system is provided as Figure 2.

Exhaust gas moisture content was evaluated usin g Method 4. Exhaust gas moisture content was be determined volumetrically (liquid impingers ) and gravimetrically (silica gel impinger).

3.2 PM and PM 2.5 

## Concentrations and Emission Rates

PM/PM 2.5 

## concentrations and emission rates were measured using U.S. EPA Other Test Methods (OTM) 27 and OTM 28. PM, PM 2.5

ELEMENTS BY ICP/MS (STACK SAMPLING TRAIN)

Metals in Combined Train (6020): Extra 2x dilution was required for all samples except HI8619, due to the matrix. Post digestion duplicate and spike was done on sample HI8620. Trace level As was observed in the Processed Blank.

Results relate only to the items tested.

Matrix Spike: A sample to which a known amount of the analyte of interest has been added. Used to evaluate sample matrix interference. Spiked Blank: A blank matrix to which a known amount of the analyte has been added. Used to evaluate analyte recovery. Method Blank: A blank matrix containing all reagents used in the analytical procedure. Used to identify laboratory contamination. NC (RPD): The RPD was not calculated. The level of analyte detected in the parent sample and its duplicate was not sufficiently significant to permit a reliable calculation.

GENERAL COMMENTS

Samples received above 6°C.

RESULTS OF ANALYSES OF STACK SAMPLING TRAIN

Hexavalent Chromium (M0061): Samples were initially analyzed within hold-time (2010-10-01) however data was not considered acceptable. Samples were re-analzyed on 2010-10-11.

Results relate only to the items tested.
