# Executive Summary

For the purpose of assisting in the developmen t of any emission standa rd 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 requi re 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 ha s 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 (NES HAP) for Wool Fiberglass Manufacturing 1



# . To assist in collecting the ag reed 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 Colle ctor 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

# 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 wh ich 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 H 2 

# O)

Process production data is availabl e in Appendix B. Control equipm ent data will be available to U.S. EPA on request.

3.0 Sampling and Analytical Methodologies

Sampling and analytical methodologies for the em issions test program can be separated into three categories as follows:

(1) Measurement of exhaust gas velocity, mo lecular 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 cate gory 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, molecula r weight, and moisture content were 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 Molecula r Weight of Dry Stack Gas”(Integrated tedlar bags) • Method 4 - “Determination of Moisture Content in Stack Gases”

These test methods were used to evaluate e xhaust gas flowrates in conjunction with the isokinetic sampling methodologies.

# Johns Manville Willows BTEC Project No. 11-4191.04 U.S. EPA Emissions Test Report February 22, 2012 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 pito t 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 Emi ssions from Stationary Sources”. The O 2 

# content of the exhaust gas was measured us ing an M&C Products PMA 100-L O 2 

# gas analyzer and the CO 2 

# content of the exhaust gas was measured usi ng a California Analytical Instruments (CAI) 600 Series CO 2 

# gas analyzer. A sample of the gas streamwas 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 en tered the analyzers. Data was recorded at 4- second intervals on a PC equipped with data acquisition software.

For O 2 

# and CO 2 

# analyzer calibrations, calibration gases were mixed to desi red concentrations using an Environics Series 4040 Computerized Gas Dilution System . The Series 4040 consists of a single chassis with four mass flow controll ers. 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 c ontroller utilizes an 11 -point calibration table with linear interpolation, to increase accuracy and reduce fl ow controller nonlinearity.

Exhaust gas moisture content wi ll be evaluated using Method 4. Exhaust gas moisture content was determined gravimetrically.

3.2 

# PM, FCr, VCr, and TCr Concen trations and Emission Rates

PM, FCr, VCr, and TCr concentrations and emission rates will be measured using the procedures of 40 CFR 60, Appendi x 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 firs t two impingers will be filled with 100 ml of a 5% nitric acid (HNO 3 

# )/10% hydrogen peroxide solution, the third impinger will be empty, and the fourth will contain approximately 300 g of s ilica 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 emissi on 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 st eel probe with a glass probe liner, (4) a Teflon tee

# Johns Manville Willows BTEC Project No. 11-4191.04 U.S. EPA Emissions Test Report February 22, 2012 4 

# 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, a nd calibrated orifice. Prior to each test, the first impinger will be filled with 150 mL of 0.1 N KOH, the next two will be filled with 75 mL of 0.1 N KOH, the fourth will be empty, and the la st impinger will contain approximately 300 g of silica gel desiccant. A schematic drawing of the Method 0061 sampling train is provided as Figure 4.

RESULTS OF ANALYSES OF STACK SAMPLING TRAIN

Particulates/Acetone Rinse (M5/315/M201): Field blank MH4659-02R contains residue after evaporation.

Particulates/Filter (M5/315/NJATM1/M201): Negative weights observed, see comments below

Maxxam # Filter Condition

MH4659-01R Normal MH4660-01R LFT MH4661-01R Normal MH4662-01R LFT

Normal Filters received in normal condition LFT Loose filter material in the petri dish

Filters were pre-weighed by the client.

ELEMENTS BY ICP/MS (STACK SAMPLING TRAIN)

Metals B.H. in H2O2/HNO3 Imp.(6020): Post digestion duplicate and spike was done on sample MH4660.

Metals F.H. in Filter + Rinses (6020): Extra 2x dilution was required for all samples except MH4659 due to the matrix Post digestion duplicate and spike was done on sample MH4660.

Results relate only to the items tested.
