Executive Summary

For the purpose of assisting in the development of any emission standard under Section 7412 of 

the Clean Air Act (CAA), Section 114 of the CAA gives the United States Environmental 

Protection Agency (U.S. EPA) authority to require that persons who operate any emission source 

“sample such emissions (in accordance with such procedures or methods, at such locations, at 

such intervals, during such periods and in such manner as the Administrator shall prescribe)”. 

Consistent with this authority, U.S. EPA has requested that Johns Manville (JM) sample 

emissions for the purpose of providing residual risk-related data for the National Emission 

Standards for Hazardous Air Pollutants (NESHAP) for Wool Fiberglass Manufacturing1. 

To assist in collecting the agreed upon data, BT Environmental Consulting, Inc. (BTEC) was 

retained by JM to evaluate emission rates of the following pollutants from one exhaust stack 

associated with the Line 133 Melter Dust Collector located at the Johns Manville plant in 

Willows, California: 

• Filterable particulate matter (PM) using U.S. EPA Methods 5/29 

• Filterable chromium (FCr) using U.S. EPA Method 29 

• Vaporous chromium (VCr) using U.S. EPA Method 29 

• Total chromium (TCr) using U.S. EPA Method 29 

• Hexavalent chromium (Cr+6) using SW-846 Method 0061 

• TCr using SW-846 Method 0061 

Table I on the following page summarizes the overall results of the emissions test program.

Notes: (1) Pollutant emission rates in terms of mg/dscm were not corrected to 7% O2 because exhaust from the 

process is essentially ambient (i.e., approximately 20.9% O2). 

(2) The “less than” symbol (<) included in the table indicates that the emission rate was calculated using the method 

detection limit (MDL) value instead of zero because the analytical result was below the MDL for one or more of the 

sample fractions.

1.0 Introduction 

For the purpose of assisting in the development of any emission standard under Section 7412 of 

the Clean Air Act (CAA), Section 114 of the CAA gives the United States Environmental 

Protection Agency (U.S. EPA) authority to require that persons who operate any emission source 

“sample such emissions (in accordance with such procedures or methods, at such locations, at 

such intervals, during such periods and in such manner as the Administrator shall prescribe)”. 

Consistent with this authority, U.S. EPA has requested that Johns Manville (JM) sample 

emissions for the purpose of providing residual risk-related data for the National Emission 

Standards for Hazardous Air Pollutants (NESHAP) for Wool Fiberglass Manufacturing2. 

To assist in collecting the agreed upon data, BT Environmental Consulting, Inc. (BTEC) was 

retained by JM to evaluate emission rates of the following pollutants from one exhaust stack 

associated with the Line 133 Melter Dust Collector located at the JM plant in Willows, 

California: 

• Filterable particulate matter (PM) using U.S. EPA Methods 5/29 

• Filterable chromium (FCr) using U.S. EPA Method 29 

• Vaporous chromium (VCr) using U.S. EPA Method 29 

• Total chromium (TCr) using U.S. EPA Method 29 

• Hexavalent chromium (Cr+6) using SW-846 Method 0061 

• TCr using SW-846 Method 0061 

The emissions test program was conducted on January 17 and 18, 2012. The test program 

consisted of triplicate 240-minute emission tests for each parameter. The field sampling portion 

of the emissions test program included the personnel summarized by Table 1.

2.0 Process Description

The Line 133 electric melter charges batch and cullet and feeds to a natural forehearth which 

distributes the glass to a series of fiberizing rotary discs which attenuate the fibers onto a 

collection mat. The three Line 133 melters exhaust through a common baghouse to a single 

stack. 

2.1 Process Monitoring 

Process and control equipment data collected during the emissions test program includes the 

following: 

(1) Melter Production Rate (lbs/hr) 

(2) Baghouse pressure drop (inches H2O) 

Process production data is available in Appendix B. Control equipment data will be available to 

U.S. EPA on request. 

3.0 Sampling and Analytical Methodologies 

Sampling and analytical methodologies for the emissions test program can be separated into 

three categories as follows: 

(1) Measurement of exhaust gas velocity, molecular weight, and moisture content; 

(2) Measurement of exhaust gas PM, FCr, VCr, and TCr concentrations and emission rates 

using Methods 5/29; and 

(3) Measurement of exhaust gas CR+6 and TCr concentrations and emission rates using 

Method 0061. 

Descriptions of sampling and analytical methodologies by category are summarized by Sections 

3.1 through 3.3, respectively. 

3.1 Exhaust Gas Velocity, Molecular Weight, and Moisture Content 

Measurement of exhaust gas velocity, molecular weight, and moisture content were conducted 

using the following reference test methods codified 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 Velocity and Volumetric Flowrate” 

• Method 3A - “Determination of Molecular Weight of Dry Stack 

Gas”(Integrated tedlar bags)

• Method 4 - “Determination of Moisture Content in Stack Gases”

These test methods were used to evaluate exhaust gas flowrates in conjunction with the 

isokinetic sampling methodologies.

U.S. EPA Emissions Test Report February 22, 2012

Stack gas velocity traverses were 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 was within specified limits, therefore, a 

baseline pitot tube coefficient of 0.84 (dimensionless) was assigned. 

Molecular weight was determined according to USEPA Method 3A, “Determination of Oxygen 

and Carbon Dioxide Concentrations in Emissions from Stationary Sources”. The O2 content of 

the exhaust gas was measured using an M&C Products PMA 100-L O2 gas analyzer and the CO2

content of the exhaust gas was measured using a California Analytical Instruments (CAI) 600 

Series CO2 gas analyzer. A sample of the gas stream was drawn through an insulated stainlesssteel probe into a heated sample line. The sample was then connected to sample conditioner to 

remove the moisture from the sample before it entered the analyzers. Data was recorded at 4-

second intervals on a PC equipped with data acquisition software. 

 

For O2 and CO2 analyzer calibrations, calibration gases were mixed to desired concentrations 

using an Environics Series 4040 Computerized Gas Dilution System. The Series 4040 consists 

of a single chassis with four mass flow controllers. The mass flow controllers are factorycalibrated using a primary flow standard traceable to the United State's National Institute of 

Standards and Technology (NIST). Each flow controller utilizes an 11-point calibration table 

with linear interpolation, to increase accuracy and reduce flow controller nonlinearity. 

Exhaust gas moisture content will be evaluated using Method 4. Exhaust gas moisture content 

was determined gravimetrically. 

3.2 PM, FCr, VCr, and TCr Concentrations and Emission Rates

PM, FCr, VCr, and TCr concentrations and emission rates will be measured using the 

procedures of 40 CFR 60, Appendix A, Methods 5 and 29. Selected metals concentrations and 

emission rates will be measured using BTEC’s Nutech® Model 2010 modular isokinetic stack 

sampling system. This system will consist of (1) a borosilicate glass or quartz nozzle, (2) a steel 

probe w/glass liner, (3) a heated quartz fiber filter assembly, (4) a set of four GS impingers, (5) 

a length of sample line, and (6) a Nutech® control case equipped with a pump, dry gas meter, 

and calibrated orifice. Prior to each test, the first two impingers will be filled with 100 ml of a 

5% nitric acid (HNO3)/10% hydrogen peroxide solution, the third impinger will be empty, and 

the fourth will contain approximately 300 g of silica gel desiccant. A schematic drawing of the 

PM/metals sampling train is provided as Figure 3. 

3.3 Cr+6 and TCr Concentrations and Emission Rates 

Measurement of Cr+6 and TCr concentrations and emission rates will be measured using the 

procedures Method 0061. Cr+6 and TCr concentrations and emission rates will be measured 

using BTEC’s Nutech® Model 2010 modular isokinetic stack sampling system. This system 

will consist of (1) a glass nozzle, (2) a heated steel probe with a glass probe liner, (4) a Teflon tee

with a recirculating pump, (5) five GS impingers, (6) a length of sample line, and (7) a Nutech®

control case equipped with a pump, dry gas meter, and calibrated orifice. Prior to each test, the 

first impinger will be filled with 150 mL of 0.1N KOH, the next two will be filled with 75 mL of 

0.1 N KOH, the fourth will be empty, and the last impinger will contain approximately 300 g of 

silica gel desiccant. A schematic drawing of the Method 0061 sampling train is provided as 

Figure 4.
