********************************************************************************
1.0 INTRODUCTION 

The Brick MACT (40 CFR Part 63, subpart JJJJJ) requires that an affected source be 

operated in compliance with the emission limitations at all times. For periods of startup, 

shutdown, and malfunction, the emission limitations do not apply; however, during these 

times, the facility must comply with a facility-developed start-up, shutdown, and 

malfunction plan (SSMP). This SSMP is applicable to the kiln, the air pollution control 

device, and the monitoring equipment. 

Boral Brick (Boral) is committed to ensuring compliance with the Brick MACT and the 

requirements in the General Provisions of Part 63 (Subpart A), which apply to all 

sources subject to an industry-specific MACT (e.g., the Brick MACT). As required by 

the Brick MACT, Boral will operate and maintain any affected source and any air 

pollution control equipment and monitoring equipment that is used to meet the standard 

in a manner consistent with safety and good air pollution control practices for minimizing 

emissions to the levels required by the relevant standards. That is, Boral will either 

meet the emission standard or comply with the startup, shutdown, and malfunction plan. 

Malfunctions will be corrected as soon as practicable after their occurrence in 

accordance with this SSMP. To the extent that an unexpected event arises during a 

startup, shutdown, or malfunction, Boral will comply by minimizing emissions during 

such a startup, shutdown, and malfunction event consistent with safety and good air 

pollution control practices. 

1.1 Facility/Operating Overview 

Boral’s Salisbury plant has two operating tunnel kilns and is a major source of 

hazardous air pollutants (HAP). Tunnel Kiln 5 is not subject to the control requirements 

of the MACT because, as allowed by §63.8390(d), “An existing tunnel kiln with a 

federally enforceable permit condition that restricts kiln operation to less than 9.07 

Mg/hr (10 tph) of fired product on a 12-month rolling average basis is not subject to the 

requirements of this subpart.” Tunnel Kiln 6 is subject to the MACT control 

requirements. 

Tunnel Kiln 6 is controlled by a dry injection fabric filter (DIFF) manufactured by E.I. 

Tec, L.P. This is equipped with two baghouse chambers, termed Scrubber 1 and 

Scrubber 2 throughout this document. The flow from the kiln can be routed through a 

single chamber during a malfunction or if access to one chamber is required for routine 

maintenance; however, this is not routine operation. The cleaning cycle of the 

baghouses is based on the pressure drop across the baghouse system, with a back-up 

timed system to protect the integrity of the system. 

The exhaust of Kiln 6 is regularly used as the heat source to dry sawdust in the sawdust 

dryer. This exhaust, which comes in direct contact with the sawdust, is not subject to 

the control requirements of the Brick MACT. While other operating scenarios could be 

added later, the only operating scenario considered “regular” for this SSMP is the use of 
both chambers using, at a minimum, the lime feedrate designated for the process 

weight rate throughput of the current operation.1 

The DIFF has both a fresh and a recycled lime flow. During normal operation, both the 

fresh and recycled lime feed are used. The flow rate for each system can be 

documented through the measurement of the Hz reading for the respective auger. A 

correlation between the Hz reading and the lime flow rate is provided in the E.I. Tec 

manual. The readings for the lime feed settings are established during performance 

tests and the setting will be documented as part of the MACT compliance.1

Boral is committed to running the control and all monitors to ensure ongoing emission 

reduction, while protecting both the integrity of the system (which ensures ongoing 

emission reduction) and safety. 

 

1 Based on conversations with NC DAQ, Boral Salisbury will be allowed to establish multiple minimum 

feed rate settings through performance testing. Each of these tests will be conducted as directed by the 

state and will be documented in the OMMP.
2.0 PURPOSE 

The purpose of this document is to comply with the MACT requirements related to 

developing and complying with a SSMP. The purpose of an SSMP [§63.6(e)(3)] is to 

ensure that a facility: 

 Is operated and maintained in a manner that meets the general duty clause to 

minimize emissions 

 Corrects malfunctions as soon as practicable in order to minimize HAP emissions 

to the environment. 

 Reduce reporting burdens associated with start-ups, shutdowns, and 

malfunctions. 

Regulatory Overview 

The general regulatory requirements cited below are addressed in our plan 

 Section 63.6(e)(3) of Subpart A, General Provisions and §63.8420(c) of Subpart 

JJJJJ requires that we develop and implement a Startup, Shutdown, and 

Malfunction Plan for operations used to comply with the Brick and Structural Clay 

Products MACT. 

 Section 63.6(e)(3) of Subpart A, General Provisions, requires Boral Salisbury to 

describe what corrective action we will take if a malfunction occurs at an affected 

process, air pollution control or monitoring equipment. 

 In addition to the requirements to develop and implement a written plan, we are 

also required to: 

– Keep records of any malfunction event that occurs and keep records of the 

actions we took to minimize emissions during the event. 

– Submit reports if procedures we took during the event are not consistent 

with the procedures we put in the plan and excess emissions occurred. 

– Revise the Malfunction Plan if a malfunction occurs that has not been 

described here or procedures for corrective action have not been 

adequately described. 

– Update the plan if requested by EPA or the appropriate State or Local Air 

Pollution Control Authority. 

************************************************************************************* 

Defining MACT Malfunctions 

Boral Salisbury may experience malfunction incidents. Please be aware 

that our operators may use a different definition of the term “malfunction” 

than the regulatory definition. We will be tracking each “incident” where a 

piece of equipment fails to operate as expected and will determine 

whether or not this event constitutes a malfunction under the MACT as 

part of this process. 
For the remainder of this document, we will use the term “MACT 

malfunction” to define an incident/malfunction that is considered a 

malfunction under §63.6(e)(3).

***********************************************************************************
3.0 START-UP, SHUTDOWN, AND MALFUNCTION PROCEDURES 

In general, the focus of our procedures is to protect both the integrity of the control 

system and reduce the emissions to the atmosphere. Boral believes that both are 

critical to ensuring the long-term emission reduction ability of the system. In addition, 

the safety of plant personnel and visitors is always the first priority. 

To balance these, Boral follows the following general principles: 

 The exhaust from the kiln is vented through the control device when the stack 

temperature is within the acceptable range. Venting at too low a temperature 

could cause moisture to enter the system and cause the lime to solidify and 

create corrosion in the system . Venting at too high a temperature could damage 

the bags which would lead to visible and gaseous emissions. [It should be noted 

that Boral uses bags appropriate for the expected temperature ranges.] 

 The exhaust must have a clear path though the system for the exhaust to be 

vented through the control. Exhausting when there is no clear path (e.g., 

dampers closed to the baghouse) would damage the control, creating potential 

safety issues and potentially damaging the integrity of the cleaning process. 

 The E.I.Tec system is equipped with two separate chambers. When possible 

during an incident/malfunction, Boral will continue to vent as much exhaust as 

possible through one of the chambers of the baghouse. Boral will ensure that 

doing so does not adversely impact worker safety or the integrity of the system. 

Venting through one of the chambers, even if there is no lime flow, will result is 

some level of emission reduction. 

All of these principles were considered when the procedures were developed. 

3.1 STARTUP PROCEDURES 

This section describes the start-up procedures for the #6 kiln and the E.I. Tec DIFF. 

The E.I. Tec DIFF was brought online while the kiln is in operation (when the 

temperature of the flue gas is in the right temperature range). 

The standard automated start-up procedure for the kiln and control device is described 

below. The same procedure is followed for each start-up of the control/kiln. However, 

some steps may be skipped if they have previously been completed. 

1. Open all ball valves in the compressed air line of the installation. 

2. Switch main switch on control panel to “ON“. 

3. Start gas fan. 

4. Push start-button on the display onto the control panel. 

- Main switch on control panel to position “ON”. 

- Press “Reset” on control panel. 
- Switch on gas fan on control panel. 

- Switch on scrubber 1 on control panel. 

- Switch on scrubber 2 on control panel. 

Steps to Minimize Emissions 

 When automatic start-up is used, the system will not start until all error codes 

have been corrected. This ensures that the control can only operate when all 

systems are operating properly, which ensures minimized emissions. 

 In order to minimize emissions, the fresh lime metering screw will be set at or 

above the minimum level established during the performance test for the current 

throughput, 2as airflow allows, for a short period during start-up to ensure that the 

baghouses fill with lime as quickly as possible. 

3.2 SHUTDOWN PROCEDURES 

There is generally a low need for shutting down the control and/or the kiln. As stated 

previously, the kiln tends to remain in operation. If the control and/or the kiln need to be 

stopped, the following general principles impact the procedures. 

 

 Unless a safety issue or control device integrity issue occurs, the kiln will 

continue to vent through the control device (or a portion of the control device) 

until the exhaust reaches the low temperature set point. 

 If control device is operational, product feed into the kiln will be stopped before 

the lime feed into the DIFF is stopped (If kiln shutdown is required). 

 Unless safety to Boral personnel and visitors or ongoing integrity of the control is 

threatened, all procedures will be aimed at minimizing avoidable emissions of 

HAP to the atmosphere. Maintaining the integrity of the system is critical to 

quickly returning the system to operational. 

 If the control must be taken offline for routine maintenance, the time will be 

documented as being part of the time allowed under the Routine Maintenance 

Bypass Allowance in Boral’s Title V Operating Permit. 

The standard procedure for a shutdown of the kiln and control device is 

described below. 

Complete Shut-down only: 

- Switch off scrubber 1 on control panel. 

- Switch off scrubber 2 on control panel. 

- Switch off gas fan on control panel. 

- Main switch on control panel to position “OFF”. 

- Close all ball valves in the compressed air line of the installation. 

 

2 See Appendix C of Salisbury’s MACT OMMP 
Maintenance/ Malfunction Shut-down: 

- Switch off scrubber 1 on control panel. 

- Switch off scrubber 2 on control panel. 

- System automatically goes to by-pass. 

Steps to Minimize Emissions 

 Unless there is a concern about the safety of personnel or maintaining the 

integrity of the control, the kiln will continue to vent through the control device 

until the exhaust reaches the low temperature set point. This ensures that the 

exhaust will be cleaned as long as the raw gas may contain harmful emissions. 
3.3 MALFUNCTION PROCEDURES 

This section describes the overall approach to identifying the cause of a malfunction 

incident, correcting it, and determining whether the incident meets the definition of a 

“MACT malfunction.” It should be noted that Boral Brick has a responsibility to assure 

worker safety and to comply with all OSHA and MSHA safety requirements. This will 

often affect the approach that must be taken to rectify a malfunction situation. Boral will 

work to minimize emissions at all times, while ensuring all other health and safety 

requirements are also met. 

Boral’s approach to minimizing emissions during a malfunction incident is to review the 

potential to minimize the two primary factors that influence overall emissions: duration 

and concentration of the emissions. 

1. Minimize the amount of time the system is shut down. To minimize the amount 

of time the DIFF is offline, Boral will: 

a. Respond as quickly as possible to each ALARM (e.g., within 30 minutes of the 

first alarm). 

b. Maintain spare parts listed in the MACT Operation, Maintenance, and Monitoring 

Plan (MACT OMMP). 

c. Personnel, trained in alarm mode and response, are onsite at all times the kiln 

and control are in operation. Additional trained staff members are on-call 24 

hours per day.

2. Minimize the amount of emissions that are vented when the control device is 

not fully operational. To ensure that the amount of emissions that are vented to 

the atmosphere are minimized, Boral will (for each incident) determine if it is 

possible to continue to vent through the control device, or part of the control device 

while the incident/MACT malfunction is being addressed (e.g., venting through the 

baghouse, even if lime flow has stopped; venting through one chamber while the 

other is being maintained). Operation in a “semi controlled” state is discussed in 

more detail below. 

Boral will either minimize the length of the downtime or the amount of emissions, or 

both, to the extent practicable during any MACT malfunction. It is important to note 

that switching to uncontrolled bypass for a short amount of time could actually 

minimize the total amount of emissions exhausted to the atmosphere. If the 

control were not bypassed, the control and/or kiln would need to be cooled over 

many hours (or days) and then restarted, which could result overall in more 

emissions. 

In addition, Boral has the potential to run in a “semi-controlled” state during periods 

where uncontrolled emissions are not prohibited under the Brick MACT. This “semicontrolled” condition would allow exhaust, or a portion of the exhaust, to flow through 

the baghouses, where some lime caking would still exist on the bags. This allows Boral 
to minimize emissions due to the malfunction (or routine maintenance discussed in the 

OMMP). By opting for “semi- controlled” operation whenever possible, Boral is meeting 

the General Duty clause to reduce emissions. 

The following sections include lists of specific procedures to be followed when an 

incident occurs that could potentially be considered a MACT malfunction under the Brick 

MACT. This list is based on a list of conditions that could have a direct impact on 

emissions, either immediately or if a situation is not corrected in sufficient time. It does 

not include other incidents that Boral reviews periodically to ensure that the control 

device is operating properly. Therefore, it is not identical to the list included in the 

E.I.Tec manual. 

The E.I.Tec DIFF has 2 categories of alarms: 

1. Shutdown Alarm – An alarm that is triggered by an event that puts personnel 

safety or equipment integrity in danger. 

2. Warning Alarm – An alarm that is triggered by an event that needs to be 

known by the operator but has no immediate impact on any other system 

components. Also an alarm that is triggered by an event that affects other 

components in the system but does not indicate current personnel equipment 

danger. 

A shutdown alarm will immediately cause the system to go into bypass and shutdown. 

This alarm is only triggered when either personnel are in danger or the integrity of the 

system could be compromised. Protecting the integrity of the system will ensure a more 

rapid return to normal operation of the control. In general, there is at least one warning 

alarm that would indicate problems before they would rise to the level of a shutdown 

alarm. 

Boral responds to warning and shutdown alarms immediately. As indicated in the 

following pages, steps are taken immediately to both identify the cause of the alarm and 

to assess whether the incident may be considered a MACT malfunction. 

The incidents/potential MACT malfunctions that have been identified are listed below 

and detailed on the following pages. 

Incident 

# 

Condition 

1 Pressure drop across baghouses too high 

2 Pressure drop across baghouse too low 

3 Lime flow too low and/or stopped (i.e., no 

“freeflowing lime” 

4 Airflow too low (could cause lime to not remain 

suspended) 

5 Visible emissions from stack 
6 High temperature in baghouse inlet 

7 Low temperature in baghouse inlet 

8 High level alarm in hopper 

9 Reduced compressed air pressure 

10 Mechanical equipment failure (to be used for key 

equipment failures before above conditions occur) 

11 Loss of power or gas 

12 Acts of God 
Type of Malfunction: Pressure Drop Higher Than Acceptable Range 

Possible Causes: Inefficient cleaning cycle in baghouse (e.g., timing or 

inefficient compressed air); faulty pressure indicator, reentrainment of lime; low fan motor amperage 

Type of Alarm: Warning Alarm

Steps Taken to Correct Problem: 

1. Check all indicators to see if root cause can be determined. 

2. If it can be determined that the high pressure reading is in error or only in one 

chamber, determine if exhaust can still safely vent through one or both baghouse 

chambers. If so, continue to vent through baghouse. If not, switch to bypass 

mode. 

3. Depending on root cause (see Appendix A), follow remedy steps listed below. 

4. If malfunction cannot be repaired in 4 hours, notify management to evaluate 

whether change in kiln operation is warranted or if other actions are warranted. 

5. Once the malfunctioning equipment has been repaired, follow start-up 

procedures. 

6. Complete all required paperwork. 

Steps Taken to Minimize Emissions: 

1. Since high pressure drop most likely indicates excessive lime on the bags, 

exhaust will continue to flow through one or both chambers of the system unless 

it will cause a danger to personnel or the equipment. This will ensure that the 

maximum possible emission reduction is still achieved during the incident. 

2. Boral will maintain spare parts recommended by E.I.Tec to ensure parts most 

likely to require replacement are available. 

INCIDENT 1- 
Type of Malfunction: Pressure Drop Across Baghouse Lower 

Than Acceptable Range 

Possible Causes: Cleaning cycle too frequent; cleaning cycle based on 

time rather than pressure drop; power failure; exhaust 

Fan Failure 

Steps Taken to Correct Problem: 

1. Stop all bag cleaning (i.e., turn off time-based cleaning as backup to pressure-drop 

based cleaning) 

2. Determine if exhaust can still safely vent through one or more baghouse modules. 

If so, continue to vent through baghouse. If not, switch to bypass mode 

3. Check all indicators to see if root cause can be determined. 

4. Depending on root cause, follow remedy steps listed in the E.I. Tec table (See 

Appendix A) 

5. If malfunction cannot be repaired in 4 hours, notify management to evaluate 

whether change in kiln operation is warranted. 

6. Once the incident has been repaired, follow start-up procedures. Temporarily 

increase lime flow, if warranted, to re-establish lime build-up on bags. 

7. Complete all required paperwork 

Steps Taken to Minimize Emissions: 

1. Stopping bag cleaning while determining cause will ensure the build-up on the 

bags is not further reduced. 

2. Continuing to flow the exhaust through one or more chambers of the control (if 

possible) will provide some amount of emission reduction. 

INCIDENT 2- 
Type of Malfunction: Limeflow Too Low and/or Stopped 

Possible Causes: Blockage before visual port; no lime in hopper, 

malfunctioning equipment 

Steps Taken to Correct Problem: 

1. Check for lime in the hopper 

2. Determine if exhaust can still safely vent through one or more chambers of 

baghouse. If so, continue to vent through baghouse. If not, switch to bypass 

mode. 

3. Discontinue bag cleaning until flow has been re-established. 

4. Identify and remove blockage, if present. 

5. If malfunction cannot be repaired in 4 hours, notify management to evaluate 

whether change in kiln operation is warranted. 

6. Once the flow has been re-established, restart cleaning process. 

7. Increase lime feed to reestablish lime in system, if necessary. 

8. Complete all required paperwork 

Steps Taken to Minimize Emissions: 

1. Since there will continue to be lime build-up on the bags, exhaust will continue to 

flow through one or both baghouse chambers unless it will cause a danger to 

personnel or the equipment. This will ensure that the maximum possible 

emission reduction is still achieved during the incident. 

2. Discontinuing bag cleaning during this incident will ensure that lime remains on 

the bags to provide the maximum amount of cleaning possible. 

INCIDENT 3
Type of Malfunction: Airflow Through System Too Low 

Possible Causes: Exhaust Fan Failure

Steps Taken to Correct Problem: 

1. Check all indicators to see if root cause can be determined. 

2. Determine if exhaust can still safely vent through one or more chambers of the 

baghouse. If so, continue to vent through baghouse. If not, switch to bypass 

mode. 

3. Discontinue baghouse cleaning if lime flow has stopped. 

4. Depending on root cause, follow remedy steps listed in E.I.Tec Manual (see 

Appendix A) 

5. If malfunction cannot be repaired in 4 hours, notify management to evaluate 

whether change in kiln operation is warranted. 

6. Once the incident has been repaired, follow start-up procedures. Increase lime 

feed for limited time to re-establish build-up on filters, if necessary 

7. Complete all required paperwork 

Taken to Minimize Emissions: 

While reduced airflow may cause the system to automatically discontinue limefeed 

(to prevent lime blockages caused by insufficient flow to maintain the lime in the air 

stream), there will still be lime caked on the baghouses. Therefore, exhaust will 

continue to flow through the system unless it will cause a danger to personnel or the 

equipment. This will ensure that the maximum possible emission reduction is still 

achieved during the incident. 

INCIDENT 4
Type of Malfunction: Visible Emissions from Stack 

Possible Causes: Bag breakage; improper duct balancing; improper 

seal at tube seat; insufficient filter cake 

Type of Alarm: None- determined from visible observation 

Steps Taken to Correct Problem: 

1. Check all monitors/indicators to see if root cause can be determined. 

2. If problem is limited to one chamber, continue to flow through one chamber, 

continue this flow while fixing problem. If the problem allows flowthe issue is 

other than bag breakage, determine if exhaust can still safely vent through 

baghouse while work continues to fix the malfunctioning equipment. If so, 

continue to vent through baghouse. If not, switch to bypass mode. 

3. Depending on root cause, follow remedy steps listed in E.I.Tec table (included in 

Appendix A). 

4. If malfunction cannot be repaired in 4 hours, notify management to evaluate 

whether change in kiln operation is warranted. 

5. Once the incident has been repaired, follow start-up procedures. 

6. Complete all required paperwork 

Steps Taken to Minimize Emissions: 

1. Boral will seek to identify whether a single bag or a limited number of bags is 

causing the visible emissions (this would most often be the case) as soon as 

practicable. Then, those bag(s) would be closed or blinded and the exhaust will 

be vented through the remaining modules. 

INCIDENT 5
Type of Malfunction: High Temperature in Baghouse Inlet 

Possible Causes: Dampers stuck on dilution vent, raw gas from Kiln 

temperature. 

Type of Alarm: Warning first; switches to bypass if temperature 

reaches 480 oF 

Steps Taken to Correct Problem: 

1. If shutdown alarm, DIFF will automatically switch to bypass to avoid damage to 

the DIFF. 

2. Check all indicators to see if root cause can be determined. 

3. If temperature remains below 500 oF, continue to vent through baghouse, unless 

there is a personnel safety or an additional control device integrity issue. 

4. Depending on root cause, follow remedy steps listed in E.I.Tec table (reproduced 

in Appendix A). 

5. If malfunction cannot be repaired in 4 hours, notify management to evaluate 

whether change in kiln operation is warranted. 

6. Once the incident has been repaired, follow start-up procedures. 

7. Complete all required paperwork 

Steps Taken to Minimize Emissions: 

1. System integrity maintained to expedite return to normal operation 

2. Bypass stopped as soon as it is possible to safely vent through system. 

INCIDENT 6
Type of Malfunction: Low Temperature in Baghouse 

Possible Causes: Raw gas temperature too low.

Steps Taken to Correct Problem: 

1. Check all indicators to see if root cause can be determined. 

2. Verify that lime is flowing to control device. 

3. Determine if exhaust can still safely vent through one or both chambers of the 

baghouse. If so, continue to vent through baghouse. If not, switch to bypass 

mode. 

4. Depending on root cause, follow remedy steps listed in E.I.Tec table (see 

Appendix A). 

5. If malfunction cannot be repaired in 4 hours, notify management to evaluate 

whether change in kiln operation is warranted. 

6. Once the incident has been repaired, follow start-up procedures. 

7. Complete all required paperwork 

Steps Taken to Minimize Emissions: 

1. Boral will identify root cause and, where possible, draw additional heat from Kiln 

raw gas. 

INCIDENT 7
Type of Malfunction: High Level Alarm in Hopper 

Possible Causes: Bridging in hopper (caused by improper air loosening, 

conveyor plugged); indicator malfunction. 

Type of Alarm: 

Steps Taken to Correct Problem: 

1. Check all indicators to see if root cause can be determined. 

2. Verify that lime is flowing to control device 

3. Determine if exhaust can still safely vent through one or both chambers of 

baghouse. If so, continue to vent through baghouse. If not, switch to bypass 

mode. 

4. Depending on root cause, follow remedy steps listed in E.I. Tec Manual (see 

table in Appendix A). Going to need to reference something else- section 5 or 10- 

or repeat information here. 

5. If malfunction cannot be repaired in 4 hours, notify management to evaluate 

whether change in kiln operation is warranted. 

6. Once the incident has been repaired, follow start-up procedures. 

7. Complete all required paperwork 

Steps Taken to Minimize Emissions: 

1. Boral will identify which hopper is high. The waste discharge system will run 

continuously until the excess lime has been removed from the cone. Emissions 

will not have increased. 

INCIDENT 8
Type of Malfunction: Reduced Compressed Air Pressure 

Possible Causes: Compressed air consumption too high; restriction in 

piping; air dryer plugged; compressor not operating 

properly 

Type of Alarm: Initial warning alarm then shut down before level 

necessary to shutdown system efficiently is reached. 

Steps Taken to Correct Problem: 

1. Check all indicators to see if root cause can be determined. 

2. Determine if exhaust can still safely vent through one or both chambers of the 

baghouse. If so, continue to vent through baghouse. If not, switch to bypass 

mode.

INCIDENT 12
4.0 RECORDKEEPING REQUIREMENTS 

We will track all start-up and shutdown events. Operating hours are defined as the time 

between the end of start-up and the beginning of shutdown. 

WHEN A POTENTIAL MALFUNCTION HAPPENS 

 For all incidents that could potentially be seen as a MACT Malfunction, an Incident 

Report Form will be completed. 

 The completed Incident Report Form should be reviewed and signed by the Shift 

Supervisor and any additional comments added. 

ACTIONS 

 Operator should notify the Shift Supervisor about the incident as soon as 

practicable. 

 If the problem cannot be corrected within a reasonable amount of time after 

detection (e.g., 4 hours), notify the Shift Supervisor. This does not mean that kiln 

operation will, or should, be affected. However, additional discussions should be 

held. 

 The operator on duty should complete the Incident Report Form prior to the end of 

the shift or no later than 24 hours following the malfunction and submit it to the Shift 

Supervisor. 

 The Shift Supervisor should review and sign the Incident Report Form and submit a 

copy to the Environmental Supervisor. Retain the original form in the shift files for 

five (5) years [§63.10(b)(1)]. 

 Enter Incident into Incident/Malfunction Log (optional) 
5.0 REPORTING REQUIREMENTS 

What Will Be Reported to Regulatory Authority When There is a Malfunction 

 If the actions taken during the malfunction were consistent with this SSMP, we 

will state this fact in our semiannual excess emissions report (due within 60 days 

following the end of each 6-month period) with the following information included 

(§63.10(d)(5)(i)): 

o Certifying signature of the owner/operator or other responsible official; 

o Statement that the actions taken during the malfunction were consistent 

with the Malfunction Plan; 

o The number, duration, and a brief description of malfunction that occurred 

during the reporting period (§63.10(d)(5)(i)) or a copy of a malfunction 

report form that includes this information (see Section 5-7 for an example 

form); 

o Whether any excess emissions and/or parameter monitoring exceedances 

are believed to have occurred during the malfunction (§63.10(d)(5)(ii)); 

and 

o Any additional information required by our State or permitting authority. 

 If the actions taken during a malfunction were not consistent with this Malfunction 

Plan, because the plan did not address the type of malfunction that occurred 

and/or the actions taken were not included in the current Malfunction Plan, and 

excess emissions occurred, the Environmental Supervisor should report the 

actions taken by telephone or facsimile (FAX) transmission within two (2) working 

days after the malfunction. A letter must then be sent within seven (7) working 

days after the malfunction. The letter should include the following information 

(§63.10(d)(5)(ii)): 

o Name, title, and certifying signature of responsible official; 

o Detailed explanation of the circumstances of the malfunction; 

o The reasons for not following the current Malfunction Plan; and 

o Any additional information required by our State or permitting authority. 

 If the actions taken during the malfunction were not consistent with the 

Malfunction Plan or did not address the particular type of malfunction that 

occurred, and the Boral Malfunction Plan should include these events or actions 

for future events, then the Environmental Supervisor at BORAL must also 

(§63.6(e)(3)(viii)): 

o Revise the Malfunction Plan within 45 days after the malfunction to include 

procedures for operating and maintaining the source during similar 

malfunction events, with a program of corrective action to address the 

malfunctions; and 

o Report the revisions of your Malfunction Plan in the semiannual excess 

emissions report (within 60 days following the end of each 6-month 

period). 
 

APPENDIX AE.I.TEC TROUBLESHOOTING GUIDE 

The following table is reproduced from the E.I. Tec manual and include approaches for 

ascertaining and correcting incidents where the control is not operating properly. It is 

reproduced in its entirety for convenience and ease of use. 

It should be noted that there are MANY items listed on this table that are not included in 

this manual because it is our determination that these events do not have the potential 

to be a “MACT Malfunction.” Many of these events could impact the efficiency of this 

control (i.e., energy efficiency), they do not have the potential to directly impact MACT 

requirements.
