Terms used in this subpart are defined in the Clean Air Act, in §63.2,
or in this section as follows:

Affirmative defense means, in the context of an enforcement proceeding,
a response or defense put forward by a defendant, regarding which the
defendant has the burden of proof, and the merits of which are
independently and objectively evaluated in a judicial or administrative
proceeding.

Bag leak detection system means systems that include, but are not
limited to, devices using triboelectric, light scattering, and other
effects to monitor relative or absolute particulate matter (PM)
emissions.

Bonded means wool fiberglass to which a phenol-formaldehyde binder has
been applied.

Building insulation means bonded wool fiberglass insulation, having a
loss on ignition of less than 8 percent and a density of less than 32
kilograms per cubic meter (kg/m3 ) (2 pounds per cubic foot [lb/ft3 ]).

Cold top electric furnace means an all-electric glass-melting furnace
that operates with a temperature of 120 °C (250 °F) or less as
measured at a location 46 to 61 centimeters (18 to 24 inches) above the
molten glass surface.

Flame attenuation means a process used to produce wool fiberglass where
molten glass flows by gravity from melting furnaces, or pots, to form
filaments that are drawn down and attenuated by passing in front of a
high-velocity gas burner flame.

Glass-melting furnace means a unit comprising a refractory vessel in
which raw materials are charged, melted at high temperature, refined,
and conditioned to produce molten glass. The unit includes foundations,
superstructure and retaining walls, raw material charger systems, heat
exchangers, melter cooling system, exhaust system, refractory brick
work, fuel supply and electrical boosting equipment, integral control
systems and instrumentation, and appendages for conditioning and
distributing molten glass to forming processes. The forming apparatus,
including flow channels, is not considered part of the glass-melting
furnace.

Glass pull rate means the mass of molten glass that is produced by a
single glass-melting furnace or that is used in the manufacture of wool
fiberglass at a single manufacturing line in a specified time period.

Hazardous Air Pollutant (HAP) means any air pollutant listed in or
pursuant to section 112(b) of the Clean Air Act.

Heavy-density product means bonded wool fiberglass insulation
manufactured on a flame attenuation manufacturing line and having a loss
on ignition of 11 to 25 percent and a density of 8 to 48 kg/m3 (0.5 to 3
lb/ft3 ).

Incinerator means an enclosed air pollution control device that uses
controlled flame combustion to convert combustible materials to
noncombustible gases. For the purposes of this rule, the term
‘incinerator’ means ‘regenerative thermal oxidizer’ (RTO).

Loss on ignition (LOI) means the percent decrease in weight of wool
fiberglass after it has been ignited. The LOI is used to monitor the
weight percent of binder in wool fiberglass.

Manufacturing line means the manufacturing equipment for the production
of wool fiberglass that consists of a forming section where molten glass
is fiberized and a fiberglass mat is formed and which may include a
curing section where binder resin in the mat is thermally set and a
cooling section where the mat is cooled.

of which is commenced after March 31, 1997.

Pipe product means bonded wool fiberglass insulation manufactured on a
flame attenuation manufacturing line and having a loss on ignition of 8
to 14 percent and a density of 48 to 96 kg/m3 (3 to 6 lb/ft3 ).

Rotary spin means a process used to produce wool fiberglass building
insulation by forcing molten glass through numerous small orifices in
the side wall of a spinner to form continuous glass fibers that are then
broken into discrete lengths by high-velocity air flow. Any process used
to produce bonded wool fiberglass building insulation by a process other
than flame attenuation is considered rotary spin.

Wool fiberglass means insulation materials composed of glass fibers made
from glass produced or melted at the same facility where the
manufacturing line is located.

Wool fiberglass manufacturing facility means any facility manufacturing
wool fiberglass on a rotary spin manufacturing line or on a flame
attenuation manufacturing line.

will be used to demonstrate compliance after the initial performance
test.

(11) During the performance test, the owner or operator of a rotary spin
manufacturing line or flame attenuation manufacturing line who plans to
use a wet scrubbing control device to comply with the emission limits in
§63.1382 must continuously monitor and record the pressure drop across
the scrubber, the scrubbing liquid flow rate, and addition of any
chemical to the scrubber, including the chemical feed rate, and
establish the minimum and/or maximum value(s) that will be used to
determine compliance after the initial performance test.

(12) During the performance test, the owner or operator of a rotary spin
manufacturing line or affected flame attenuation manufacturing line
shall continuously record the operating temperature of each incinerator

rotary spin or flame attenuation manufacturing line regulated by this
subpart may conduct short-term experimental production runs using binder
formulations or other process modifications where the process parameter
values would be outside those established during performance tests
without first conducting performance tests. Such runs must not exceed 1
week in duration unless the Administrator approves a longer period. The
owner or operator must notify the Administrator and postmark or deliver
the notification at least 15 days prior to commencement of the

(g) Affirmative Defense for Exceedance of Emission Limit During
Malfunction. In response to an action to enforce the standards set forth
in this subpart, you may assert an affirmative defense to a claim for
civil penalties for exceedances of such standards that are caused by
malfunction, as defined at §63.2. Appropriate penalties may be
assessed, however, if you fail to meet your burden of proving all of the
requirements in the affirmative defense. The affirmative defense must
not be available for claims for injunctive relief.

(1) To establish the affirmative defense in any action to enforce such a
limit, you must timely meet the notification requirements in §63.1386
of this subpart, and must prove by a preponderance of evidence that:

(i) The excess emissions: 

(A) Were caused by a sudden, infrequent, and unavoidable failure of air
pollution control and monitoring equipment, process equipment, or a
process to operate in a normal or usual manner; and

(B) Could not have been prevented through careful planning, proper
design or better operation and maintenance practices; and 

(C) Did not stem from any activity or event that could have been
foreseen and avoided, or planned for; and

(D) Were not part of a recurring pattern indicative of inadequate
design, operation, or maintenance.

(ii) Repairs were made as expeditiously as possible when the applicable
emissions limitations were being exceeded. Off-shift and overtime labor
were used, to the extent practicable to make these repairs; and

(iii) The frequency, amount and duration of the excess emissions
(including any bypass) were minimized to the maximum extent practicable
during periods of such emissions; and

(iv) If the excess emissions resulted from a bypass of control equipment
or a process, then the bypass was unavoidable to prevent loss of life,
personal injury, or severe property damage; and

(v) All possible steps were taken to minimize the impact of the excess
emissions on ambient air quality, the environment and human health; and

(vi) All emissions monitoring and control systems were kept in operation
if at all possible, consistent with safety and good air pollution
control practices; and

(vii) All of the actions in response to the excess emissions were
documented by properly signed, contemporaneous operating logs; and 

(viii) At all times, the affected source was operated in a manner
consistent with good practices for minimizing emissions; and

(ix) A written root cause analysis has been prepared, the purpose of
which is to determine, correct, and eliminate the primary causes of the
malfunction and the excess emissions resulting from the malfunction
event at issue. The analysis must also specify, using best monitoring
methods and engineering judgment, the amount of excess emissions that
were the result of the malfunction. 

(2) Notification. The owner or operator of the affected source
experiencing an exceedance of its emissions limit(s) during a
malfunction, must notify the Administrator by telephone or facsimile
transmission as soon as possible, but no later than two business days
after the initial occurrence of the malfunction, if he/she wishes to be
able to use an affirmative defense to civil penalties for that
malfunction. The owner or operator seeking to assert an affirmative
defense must also submit a written report to the Administrator within 45
days of the initial occurrence of the exceedance of the standards in
this subpart. This report must demonstrate that the owner/operator has
met the requirements set forth in paragraph (g) of this section and must
include all necessary supporting documentation. The owner or operator
may seek an extension of this deadline for up to 30 additional days by
submitting a written request to the Administrator before the expiration
of the 45 day period. Until a request for an extension has been approved
by the Administrator, the owner or operator is subject to the
requirement to submit such report within 45 days of the initial
occurrence of the exceedance.

Appendix A to Subpart NNN of Part 63—Method for the Determination of
LOI

1. Purpose

The purpose of this test is to determine the LOI of cured blanket
insulation. The method is applicable to all cured board and blanket
products.

2. Equipment

2.1  Scale sensitive to 0.1 gram.

2.2  Furnace designed to heat to at least 540 °C (1,000 °F) and
controllable to ±10 °C (50 °F).

2.3  Wire tray for holding specimen while in furnace.

3. Procedure

3.1  Cut a strip along the entire width of the product that will weigh
at least 10.0 grams. Sample should be free of dirt or foreign matter.

Note: Remove all facing from sample.

3.2  Cut the sample into pieces approximately 12 inches long, weigh to
the nearest 0.1 gram and record. Place in wire tray. Sample should not
be compressed or overhang on tray edges.

Note: On air duct products, remove shiplaps and overspray.

3.3  Place specimen in furnace at 540 °C (1,000 °F), ±10 °C (50
°F) for 15 to 20 minutes to insure complete oxidation. After ignition,
fibers should be white and should not be fused together.

3.4  Remove specimen from the furnace and cool to room temperature.

3.5  Weigh cooled specimen and wire tray to the nearest 0.1 gram.
Deduct the weight of the wire tray and then calculate the loss in weight
as a percent of the original specimen weight.

Appendix B to Subpart NNN of Part 63—Free Formaldehyde Analysis of
Insulation Resins by Hydroxylamine Hydrochloride

1. Scope

This method was specifically developed for water-soluble phenolic resins
that have a relatively high free-formaldehyde (FF) content such as
insulation resins. It may also be suitable for other phenolic resins,
especially those with a high FF content.

2. Principle

2.1  a. The basis for this method is the titration of the hydrochloric
acid that is liberated when hydroxylamine hydrochloride reacts with
formaldehyde to form formaldoxine:

HCHO + NH2OH:HCl → CH2:NOH + H2O + HCl

b. Free formaldehyde in phenolic resins is present as monomeric
formaldehyde, hemiformals, polyoxymethylene hemiformals, and
polyoxymethylene glycols. Monomeric formaldehyde and hemiformals react
rapidly with hydroxylamine hydrochloride, but the polymeric forms of
formaldehyde must hydrolyze to the monomeric state before they can
react. The greater the concentration of free formaldehyde in a resin,
the more of that formaldehyde will be in the polymeric form. The
hydrolysis of these polymers is catalyzed by hydrogen ions.

2.2  The resin sample being analyzed must contain enough free
formaldehyde so that the initial reaction with hydroxylamine
hydrochloride will produce sufficient hydrogen ions to catalyze the
depolymerization of the polymeric formaldehyde within the time limits of
the test method. The sample should contain approximately 0.3 grams free
formaldehyde to ensure complete reaction within 5 minutes.

3. Apparatus

3.1  Balance, readable to 0.01 g or better.

3.2  pH meter, standardized to pH 4.0 with pH 4.0 buffer and pH 7 with
pH 7.0 buffer.

3.3  50-mL burette for 1.0 N sodium hydroxide.

3.4  Magnetic stirrer and stir bars.

3.5  250-mL beaker.

3.6  50-mL graduated cylinder.

3.7  100-mL graduated cylinder.

3.8  Timer.

4. Reagents

4.1  Standardized 1.0 N sodium hydroxide solution.

4.2  Hydroxylamine hydrochloride solution, 100 grams per liter, pH
adjusted to 4.00.

4.3  Hydrochloric acid solution, 1.0 N and 0.1 N.

4.4  Sodium hydroxide solution, 0.1 N.

4.5  50/50 v/v mixture of distilled water and methyl alcohol.

5. Procedure

5.1  Determine the sample size as follows:

a. If the expected FF is greater than 2 percent, go to Part A to
determine sample size.

b. If the expected FF is less than 2 percent, go to Part B to determine
sample size.

c. Part A: Expected FF ≥ 2 percent.

Grams resin = 60/expected percent FF

i. The following table shows example levels:

Expected % free formaldehyde	Sample size, grams

2	30.0

5	12.0

8	7.5

10	6.0

12	5.0

15	4.0



ii. It is very important to the accuracy of the results that the sample
size be chosen correctly. If the milliliters of titrant are less than 15
mL or greater than 30 mL, reestimate the needed sample size and repeat
the tests.

d. Part B: Expected FF < 2 percent

Grams resin = 30/expected percent FF

i. The following table shows example levels:

Expected % free formaldehyde	Sample size, grams

2	15

1	30

0.5	60



ii. If the milliliters of titrant are less than 5 mL or greater than 30
mL, reestimate the needed sample size and repeat the tests.

5.2  Weigh the resin sample to the nearest 0.01 grams into a 250-mL
beaker. Record sample weight.

5.3  Add 100 mL of the methanol/water mixture and stir on a magnetic
stirrer. Confirm that the resin has dissolved.

5.4  Adjust the resin/solvent solution to pH 4.0, using the
prestandardized pH meter, 1.0 N hydrochloric acid, 0.1 N hydrochloric
acid, and 0.1 N sodium hydroxide.

5.5  Add 50 mL of the hydroxylamine hydrochloride solution, measured
with a graduated cylinder. Start the timer.

5.6  Stir for 5 minutes. Titrate to pH 4.0 with standardized 1.0 N
sodium hydroxide. Record the milliliters of titrant and the normality.

6. Calculations

 

7. Method Precision and Accuracy

Test values should conform to the following statistical precision:

Variance = 0.005

Standard deviation = 0.07

95% Confidence Interval, for a single determination = 0.2
