SUMMARY

This is a class II, synthetic minor permit issued to Guardian Fiberglass, Inc. located in Kingman, Arizona. 

Guardian Fiberglass manufactures wool fiberglass insulation sheets and shredded wool fiberglass, for use 

in commercial and residential buildings. 

This facility operates an electric melter and a natural gas fired, 5.83 MMBtu/hr forehearth oven to melt 

the raw material before sending it through fiber forming units comprised of 8 identical 9.6 MMBtu/hr 

process heaters. In addition, Guardian Fiberglass operates an 18 MMBtu/hr oven to be used for curing of 

the resinated fiberglass.

There are three stacks at the facility; EP1, associated with the Forming and Collection Process, EP2, 

associated with the Melting and Refining Process, and EP3, associated with Curing and Cooling Process. 

The emissions, from the stacks, are controlled by one thermal oxidizer on EP3, two dust collectors on 

EP2, one wet scrubber, three water sprays and dropout boxes on EP1. In addition, there is a baghouse 

installed on the blow wool baggers area. Guardian fiberglass also operates a continuous monitoring 

system on EP1 to monitor emissions of carbon monoxide.

Maximum production capacity of the unit is 8000 pounds per hour (lb/hr) of which 7000 pounds per hour 

may be allocated to resinated fiberglass production. Operating 8760 hours per year at maximum 

production rate of 8000 pounds per hour, Guardian Fiberglass emits less than 100 tons per year of all 

criteria pollutants. Following table lists the PTEs for each pollutant:

A. Excess Emissions Reporting

[A.A.C. R18-2-310.01.A and -310.01.B]

1. Excess emissions shall be reported as follows:

a. The Permittee shall report to the Director any emissions in excess of the 

limits established by this permit. Such report shall be in two parts as 

specified below:

(1) Notification by telephone or facsimile within 24 hours of the 

time when the Permittee first learned of the occurrence of excess 

emissions including all available information from Condition 

XII.A.1.b below.

(2) Detailed written notification by submission of an excess 

emissions report within 72 hours of the notification pursuant to 

Condition XII.A.1.a. (1) above.

b. The report shall contain the following information:

(1) Identity of each stack or other emission point where the excess 

emissions occurred;

(2) Magnitude of the excess emissions expressed in the units of the 

applicable emission limitation and the operating data and 
Permit No. 29072 Page 7 of 45 10/17/2011

calculations used in determining the magnitude of the excess 

emissions;

(3) Date, time and duration, or expected duration, of the excess 

emissions;

(4) Identity of the equipment from which the excess emissions 

emanated;

(5) Nature and cause of such emissions;

(6) If the excess emissions were the result of a malfunction, steps 

taken to remedy the malfunction and the steps taken or planned 

to prevent the recurrence of such malfunctions; and 

(7) Steps taken to limit the excess emissions. If the excess 

emissions resulted from start-up or malfunction, the report shall 

contain a list of the steps taken to comply with the permit 

procedures.

2. In the case of continuous or recurring excess emissions, the notification 

requirements of this section shall be satisfied if the source provides the required 

notification after excess emissions are first detected and includes in such 

notification an estimate of the time the excess emissions will continue. Excess 

emissions occurring after the estimated time period, or changes in the nature of 

the emissions as originally reported, shall require additional notification pursuant 

to Condition XII.A.1 above.

[A.A.C. R18-2-310.01.C]

B. Permit Deviations Reporting

[A.A.C. R18-2-306.A.5.b]

The Permittee shall promptly report deviations from permit requirements, including those 

attributable to upset conditions as defined in the permit, the probable cause of such 

deviations, and any corrective actions or preventive measures taken. Prompt reporting 

shall mean that the report was submitted to the Director by certified mail, facsimile, or 

hand delivery within two working days of the time the deviation occurred.

C. Emergency Provision

[A.A.C. R18-2-306.E]

1. An “emergency” means any situation arising from sudden and reasonable 

unforeseeable events beyond the control of the source, including acts of God, that 

require immediate corrective action to restore normal operation, and that causes 

the source to exceed a technology-based emission limitation under the permit, 

due to unavoidable increases in emissions attributable to the emergency. An 

emergency shall not include noncompliance to the extent caused by improperly 

designed equipment, lack of preventative maintenance, careless or improper 

operation, or operator error.
Permit No. 29072 Page 8 of 45 10/17/2011

2. An emergency constitutes an affirmative defense to an action brought for 

noncompliance with such technology-based emission limitations if Condition 

XII.C.3 is met.

3. The affirmative defense of emergency shall be demonstrated through properly 

signed, contemporaneous operating logs, or other relevant evidence that:

a. An emergency occurred and that the Permittee can identify the cause(s) 

of the emergency;

b. The permitted facility was being properly operated at the time;

c. During the period of the emergency, the Permittee took all reasonable 

steps to minimize levels of emissions that exceeded the emissions 

standards or other requirements in the permit; and

d. The Permittee submitted notice of the emergency to the Director by 

certified mail, facsimile, or hand delivery within two working days of the 

time when emission limitations were exceeded due to the emergency. 

This notice shall contain a description of the emergency, any steps taken 

to mitigate emissions, and corrective action taken.

4. In any enforcement proceeding, the Permittee seeking to establish the occurrence 

of an emergency has the burden of proof.

5. This provision is in addition to any emergency or upset provision contained in 

any applicable requirement.

D. Compliance Schedule

[ARS § 49-426.I.5]

For any excess emission or permit deviation that cannot be corrected with 72 hours, the 

Permittee is required to submit a compliance schedule to the Director within 21 days of 

such occurrence. The compliance schedule shall include a schedule of remedial 

measures, including an enforceable sequence of actions with milestones, leading to 

compliance with the permit terms or conditions that have been violated.

E. Affirmative Defenses for Excess Emissions Due to Malfunctions, Startup, and Shutdown

[A.A.C. R18-2-310]

1. Applicability

This rule establishes affirmative defenses for certain emissions in excess of an 

emission standard or limitation and applies to all emission standards or 

limitations except for standards or limitations:

a. Promulgated pursuant to Sections 111 or 112 of the Act;
Permit No. 29072 Page 9 of 45 10/17/2011

b. Promulgated pursuant to Titles IV or VI of the Clean Air Act;

c. Contained in any Prevention of Significant Deterioration (PSD) or New 

Source Review (NSR) permit issued by the U.S. EPA;

d. Contained in A.A.C. R18-2-715.F; or

e. Included in a permit to meet the requirements of A.A.C. R18-2-406.A.5.

2. Affirmative Defense for Malfunctions

Emissions in excess of an applicable emission limitation due to malfunction shall 

constitute a violation. When emissions in excess of an applicable emission 

limitation are due to a malfunction, the Permittee has an affirmative defense to a 

civil or administrative enforcement proceeding based on that violation, other than 

a judicial action seeking injunctive relief, if the Permittee has complied with the 

reporting requirements of A.A.C. R18-2-310.01 and has demonstrated all of the 

following:

a. The excess emissions resulted from a sudden and unavoidable 

breakdown of process equipment or air pollution control equipment 

beyond the reasonable control of the Permittee;

b. The air pollution control equipment, process equipment, or processes 

were at all times maintained and operated in a manner consistent with 

good practice for minimizing emissions;

c. If repairs were required, the repairs were made in an expeditious fashion 

when the applicable emission limitations were being exceeded. Off-shift 

labor and overtime were utilized where practicable to ensure that the 

repairs were made as expeditiously as possible. If off-shift labor and 

overtime were not utilized, the Permittee satisfactorily demonstrated that 

the measures were impracticable;

d. The amount and duration of the excess emissions (including any bypass 

operation) were minimized to the maximum extent practicable during 

periods of such emissions;

e. All reasonable steps were taken to minimize the impact of the excess 

emissions on ambient air quality;

f. The excess emissions were not part of a recurring pattern indicative of 

inadequate design, operation, or maintenance;

g. During the period of excess emissions there were no exceedances of the 

relevant ambient air quality standards established in Title 18, Chapter 2, 
Permit No. 29072 Page 10 of 45 10/17/2011

Article 2 of the Arizona Administrative Code that could be attributed to 

the emitting source;

h. The excess emissions did not stem from any activity or event that could 

have been foreseen and avoided, or planned, and could not have been 

avoided by better operations and maintenance practices;

i. All emissions monitoring systems were kept in operation if at all 

practicable; and

j. The Permittee's actions in response to the excess emissions were 

documented by contemporaneous records

3. Affirmative Defense for Startup and Shutdown

a. Except as provided in Condition XII.E.3.b below, and unless otherwise 

provided for in the applicable requirement, emissions in excess of an 

applicable emission limitation due to startup and shutdown shall 

constitute a violation. When emissions in excess of an applicable 

emission limitation are due to startup and shutdown, the Permittee has an 

affirmative defense to a civil or administrative enforcement proceeding 

based on that violation, other than a judicial action seeking injunctive 

relief, if the Permittee has complied with the reporting requirements of 

A.A.C. R18-2-310.01 and has demonstrated all of the following:

(1) The excess emissions could not have been prevented through 

careful and prudent planning and design;

(2) If the excess emissions were the result of a bypass of control 

equipment, the bypass was unavoidable to prevent loss of life, 

personal injury, or severe damage to air pollution control 

equipment, production equipment, or other property;

(3) The air pollution control equipment, process equipment, or 

processes were at all times maintained and operated in a manner 

consistent with good practice for minimizing emissions;

(4) The amount and duration of the excess emissions (including any 

bypass operation) were minimized to the maximum extent 

practicable during periods of such emissions;

(5) All reasonable steps were taken to minimize the impact of the 

excess emissions on ambient air quality;

(6) During the period of excess emissions there were no 

exceedances of the relevant ambient air quality standards 

established in Title 18, Chapter 2, Article 2 of the Arizona 
Permit No. 29072 Page 11 of 45 10/17/2011

Administrative Code that could be attributed to the emitting 

source;

(7) All emissions monitoring systems were kept in operation if at all 

practicable; and

(8) Contemporaneous records documented the Permittee’s actions in 

response to the excess emissions.

b. If excess emissions occur due to a malfunction during routine startup and 

shutdown, then those instances shall be treated as other malfunctions 

subject to Condition XII.E.2 above.

4. Affirmative Defense for Malfunctions During Scheduled Maintenance

If excess emissions occur due to a malfunction during scheduled maintenance, 

then those instances will be treated as other malfunctions subject to Condition 

XII.E.2 above.

5. Demonstration of Reasonable and Practicable Measures

For an affirmative defense under Condition XII.E.2 or XII.E.3 above, the 

Permittee shall demonstrate, through submission of the data and information 

required by Condition XII.E and A.A.C. R18-2-310.01, that all reasonable and 

practicable measures within the Permittee’s control were implemented to prevent 

the occurrence of the excess emissions.

XIII. RECORD KEEPING REQUIREMENTS

[A.A.C. R18-2-306.A.4]

regulations.

XVII. FACILITY CHANGE WITHOUT A PERMIT REVISION

[A.A.C. R18-2-306.A.4 and -317.02]

A. Except for a physical change or change in the method of operation at a Class II source 

requiring a permit revision under A.A.C. R18-2-317.01, or a change subject to logging or 

notice requirements in Conditions XVII.B and XVII.C below, a change at a Class II

source shall not be subject to revision, notice, or logging requirements under this Section.

B. Except as otherwise provided in the conditions applicable to an emissions cap created 

under A.A.C. R18-2-306.02, the following changes may be made if the source keeps on 

site records of the changes according to Appendix 3 of the Arizona Administrative Code:

1. Implementing an alternative operating scenario, including raw materials changes;

2. Changing process equipment, operating procedures, or making any other physical 

change if the permit requires the change to be logged;

3. Engaging in any new insignificant activity listed in A.A.C. R18-2-101.57.a 

through A.A.C. R18-2-101.57.i but not listed in the permit;

4. Replacing an item of air pollution control equipment listed in the permit with an 

identical (same model, different serial number) item. The Director may require 

verification of efficiency of the new equipment by performance tests; and

5. A change that results in a decrease in actual emissions if the source wants to 

claim credit for the decrease in determining whether the source has a net 

emissions increase for any purpose. The logged information shall include a 

description of the change that will produce the decrease in actual emissions. A 

decrease that has not been logged is creditable only if the decrease is 

quantifiable, enforceable, and otherwise qualifies as a creditable decrease.

C. Except as provided in the conditions applicable to an emissions cap created under A.A.C. 

R18-2-306.02, the following changes may be made if the source provides written notice 

to the Department in advance of the change as provided below:

1. Replacing an item of air pollution control equipment listed in the permit with one 

that is not identical but that is substantially similar and has the same or better 

pollutant removal efficiency: 7 days. The Director may require verification of 

efficiency of the new equipment by performance tests;

2. A physical change or change in the method of operation that increases actual 

emissions more than 10% of the major source threshold for any conventional 

pollutant but does not require a permit revision: 7 days;
Permit No. 29072 Page 14 of 45 10/17/2011

3. Replacing an item of air pollution control equipment listed in the permit with one 

that is not substantially similar but that has the same or better efficiency: 30 days. 

The Director may require verification of efficiency of the new equipment by 

performance tests;

4. A change that would trigger an applicable requirement that already exists in the 

permit: 30 days unless otherwise required by the applicable requirement;

5. A change that amounts to reconstruction of the source or an affected facility: 7 

days. For the purposes of this subsection, reconstruction of a source or an 

affected facility shall be presumed if the fixed capital cost of the new 

components exceeds 50% of the fixed capital cost of a comparable entirely new 

source or affected facility and the changes to the components have occurred over 

the 12 consecutive months beginning with commencement of construction; and

6. A change that will result in the emissions of a new regulated air pollutant above 

an applicable regulatory threshold but that does not trigger a new applicable 

requirement for that source category: 30 days. For purposes of this requirement, 

an applicable regulatory threshold for a conventional air pollutant shall be 10% 

of the applicable major source threshold for that pollutant.

D. For each change under Condition XVII.C above, the written notice shall be by certified 

mail or hand delivery and shall be received by the Director the minimum amount of time 

in advance of the change. Notifications of changes associated with emergency 

conditions, such as malfunctions necessitating the replacement of equipment, may be 

provided with less than required notice, but must be provided as far in advance of the 

change, or if advance notification is not practicable, as soon after the change as possible. 

The written notice shall include:

1. When the proposed change will occur;

2. A description of the change;

3. Any change in emissions of regulated air pollutants; and

4. Any permit term or condition that is no longer applicable as a result of the 

change.

E. A source may implement any change in Condition XVII.C above without the required 

notice by applying for a minor permit revision under A.A.C. R18-2-319 and complying 

with subsection A.A.C. R18-2-319.D.2 and A.A.C. R18-2-319.G.

F. The permit shield described in A.A.C. R18-2-325 shall not apply to any change made 

under this Section, other than implementation of an alternate operating scenario under 

Condition XVII.B.1.
Permit No. 29072 Page 15 of 45 10/17/2011

method. Each run shall be conducted for the time and under the conditions specified in 

the applicable standard. For the purpose of determining compliance with an applicable 

standard, the arithmetic mean of the results of the three runs shall apply. In the event that 
Permit No. 29072 Page 17 of 45 10/17/2011

a sample is accidentally lost or conditions occur in which one of the three runs is required 

to be discontinued because of forced shutdown, failure of an irreplaceable portion of the 

sample train, extreme meteorological conditions, or other circumstances beyond the 

Permittee’s control, compliance may, upon the Director’s approval, be determined using 

the arithmetic mean of the results of the other two runs. If the Director or the Director’s 

designee is present, tests may only be stopped with the Director’s or such designee’s 

approval. If the Director or the Director’s designee is not present, tests may only be 

stopped for good cause. Good cause includes: forced shutdown, failure of an 

irreplaceable portion of the sample train, extreme meteorological conditions, or other 

circumstances beyond the Permittee’s control. Termination of any test without good 

cause after the first run is commenced shall constitute a failure of the test. Supporting 

documentation, which demonstrates good cause, must be submitted.

G. Report of Final Test Results

A written report of the results of all performance tests shall be submitted to the Director 

within 30 days after the test is performed. The report shall be submitted in accordance
