2. Vapor processing systems utilizing a flare stack to destruct the collected VOC's will be exempt from testing and must be designed and operated in accordance with LAC 33:III.3741.D.
3. Immediately prior to the performance test for determination of compliance, all potential sources of vapor leakage in the facility's vapor collection system equipment shall be monitored for leaks using Method 21. The monitoring shall be conducted only while a ship or barge is being loaded and should cover all parts of the vapor system, including tank hatches, that operate at pressures above atmospheric pressure. All leaks shall be repaired prior to conducting the performance test.
4. The test procedure for determining compliance with LAC 33:III.2108.C.3 shall be that specified below:
a. All testing equipment shall be prepared and installed as specified in the appropriate test methods.
b. The time period for a performance test shall be not less than three hours. As much as possible, testing should be conducted during the three-hour period in which the highest emissions normally occur (near the end of the loading).
c. For intermittent vapor processing systems:
i. the vapor holder level shall be recorded at the start of the performance test. The end of the performance test shall coincide with a time when the vapor holder is at its original level;
ii. at least two startups and shutdowns of the vapor processor shall occur during the performance test. If this does not occur under automatically-controlled operation, the system shall be manually controlled.
d. The volume of crude oil, gasoline and volatile organic compounds loaded during the performance test period, whose vapor emissions are controlled by the processing system being tested, shall be determined.
e. An emission testing interval shall consist of each five-minute period during the performance test. For each interval:
i. the reading from each measurement instrument shall be recorded, and
ii. the volume exhausted and the average total organic compounds concentration in the exhaust vent shall be determined, as specified in the appropriate test method. The average total organic compounds concentration shall correspond to the volume measurement by taking into account the sampling system response time.
f. The mass emitted during each testing interval shall be calculated as follows:
Mei = (10^-6)(K)(Ves)(Ce)
where:
Mei = mass of total organic compounds emitted during testing interval i, mg.
Ves = volume of air-vapor mixture exhausted, m^3, at standard conditions.
Ce = total organic compounds concentration (as measured) at the exhaust vent, ppmv.
K = density of calibration gas, mg/m^3, at standard conditions.
= 1.83 x 10^6 for propane
= 2.41 x 10^6 for butane.
s = standard conditions, 20 degrees C and 760 mm Hg.
g. The total organic compounds mass emissions shall be
calculated as follows:
Sum from i = 1 to n {Mei}
E = --------------------------
L
where:
E = mass of total organic compounds emitted per volume of crude oil, gasoline and volatile organic compounds loaded, mg./liter.
Mei = mass of total organic compounds emitted during testing interval i, mg.
L = total volume of crude oil, gasoline and volatile organic compounds loaded, liters.
n = number of testing intervals.
5. The owner or operator may adjust the emission results to exclude the methane and ethane content in the exhaust vent by the chromatographic method shown in Method 25.
F. Reporting and Recordkeeping
1. The results of any testing done in accordance with LAC 33:III.2108.E. shall be reported to the administrative authority within 45 days of the test.
2. The following records shall be kept on file at the affected facility for at least two years and shall be made available for inspection by a representative of the administrative authority on request:
a. Daily throughput of liquid by type.
b. Daily record of the number of each type of vessel loaded and the type and quantity of each liquid loaded on each vessel.
c. Records of all replacements or additions of components performed on the vapor processing system.
d. Records on control equipment operating parameters such as monitoring for breakthrough on carbon adsorption devices, pump amperes and temperatures in refrigeration systems.
e. If any loadings are conducted which result in emissions exceeding those listed in Section 2108.C.3 a record of the name, owner, type and quantity of liquid loaded, the date of loading and the vessel's last internal examination dates listed on its certificate of inspection shall be maintained for three years.
G. Operation and Maintenance
1. No person may load gasoline, crude oil or other VOCs into ships or barges at affected facilities unless all loading and vapor lines, arms and hoses are equipped with fittings which make vapor-tight connections and provide tight shut-off when disconnected.
2. Provisions must be made to prevent spills or leaks during attachment or disconnection of filling lines, hoses or arms. Liquids subject to this rule shall not be spilled or handled in any other manner that would result in evaporation to the atmosphere.
3. All equipment associated with the loading of gasoline, crude oil or other VOC's into ships or barges at affected facilities shall be maintained to be leak-free, gas-tight and in good working order.
H. Safety/Emergency
Nothing in this rule shall be construed to:
1. require any act or omission that would be in violation of any regulation or other requirement of the United States Coast Guard or;
2. prevent any act or omission that is necessary to secure the safety of a vessel or for saving life at sea.

Section 2121. Fugitive Emission Control. LAc60
Approved by EPA 05/05/94 (59 FR 23166) at 52.970(c)(60) effective 06/06/94.
A. Applicability. This regulation is applicable to equipment in petroleum refineries, natural gas processing plants, the synthetic organic chemical manufacturing industry (SOCMI), the methyl tertiary butyl ether (MTBE) manufacturing industry, and the polymer manufacturing industry.
B. Fugitive Emission Control Requirements
1. No component shall be allowed to leak organic compounds exceeding 10,000 parts per million by volume (ppmv), as defined in LAC 33:III.111, when tested by Method 21 "Determination of Volatile Organic Compound Leaks" in the Division's Source Test Manual.
Any regulated component observed leaking by sight, sound, or smell must be repaired according to 2121.B.3, regardless of the leak's concentration. This includes flange and connection leaks found per 2121.C.3.b, pump and compressor seal leaks found during the weekly visual inspections, and any other regulated component found leaking.
2. No valve, except safety pressure relief valves, valves on sample lines, valves on drain lines and valves that can be removed and replaced without a shutdown, shall be located at the end of a pipe or line containing volatile organic compounds unless the end of such line is sealed with a second valve, a blind flange, a plug, or a cap. Such sealing devices may be removed only when the line is in use, for example, when a sample is being taken. When the line has been used and is subsequently resealed, the upstream valve shall be closed first, followed by the sealing device.
3. The operator shall make every reasonable effort to repair a leaking component, as described in LAC 33:III.2121.B within 15 days. If the component can be isolated or bypassed so as to significantly reduce or eliminate leakage, or if the repair of a component would require a unit shutdown, and if the shutdown would create more emissions than the repair would eliminate, the repair may be delayed to the next scheduled shutdown. An early unit shutdown may be ordered if leaking component losses become excessive.
C. Monitoring Requirements. The monitoring of the affected components shall be performed by the following schedule using the method described in LAC 33:III.2121.B:
1. Petroleum Refineries, SOCMI, MTBE, and Polymer Manufacturing Industry:
a. Monitor with a leak detection device one time per year (annually) the following items:
i. pump seals;
ii. pipeline valves in liquid service; and
iii. process drains.

i. compressor seals;
ii. pipeline valves in gas service;
iii. pressure relief valves in gas service;
iv. valves in light liquid service at SOCMI, MTBE, and Polymer Manufacturing Plants,
v. pumps in light liquid service at SOCMI, MTBE, and Polymer Manufacturing Plants, and
vi. valves in gas service at SOCMI, MTBE, and Polymer Manufacturing Plants.
c. Monitor pump seals visually 52 times a year (weekly).
2. Natural gas processing plants:
a. Monitor pump seals and compressor seals visually 52 times a year (weekly).
b. Monitor with a leak detection device four times a year (quarterly):
i. pumps, pump and compressor seals;
ii. valves; and
iii. pressure relief valves in gas service.
3. All listed in Paragraphs 1 and 2 above.
a. Monitor with a leak detection device any pressure relief valve within 24 hours after it has vented to the atmosphere (For natural gas processing plants an immediate visual evaluation will be made).
b. Monitor immediately with a leak detection device any component that appears to be leaking on the basis of sight, smell, or sound. In lieu of monitoring, the operator may elect to implement actions as specified in LAC 33:III.2121.B.
4. Exemptions. Monitoring is not required on the following:
a. components subject to LAC 33:III.2121.C.1 (petroleum refineries, SOCMI, MTBE, and polymer manufacturing industry) which contact a process fluid that contains less than 10 percent VOC by volume or components subject to LAC 33:III.2121.C.2 (Natural Gas Processing Plants) which contact a process fluid that contains less than 1.0 percent VOC by weight.

i. pumps and compressors with double mechanical seal.
j. research and development pilot facilities and small facilities with less than 100 valves in gas or liquid service.
5. Alternate Monitoring Program. Any facility which already has in place a fugitive emission monitoring program which controls to a higher degree than required under this Section shall be exempted from this Section upon submittal of a description of the program to the administrative authority*.
D. Alternate Control Techniques. The monitoring schedule in LAC 33:III.2121.C may be modified as follows:
1. Alternate Standards for Valves and Pumps subject to LAC 33:III.2121.C.1.b - Skip Period Leak Detection and Repair:
a. An owner or operator may elect to comply with one of the alternative work practices specified in LAC 33:III.2121.D.1.b and c. However, the administrative authority must be notified before implementing one of the alternative work practices.
b. After two consecutive quarterly leak detection periods with the percent of components leaking equal to or less than 2.0, an owner or operator may begin to skip one of the quarterly leak detection periods for the valves in gas/vapor and liquid service and pumps in light liquid service.
c. After five consecutive quarterly leak detection periods with the percent of components leaking equal to or less than 2.0, an owner or operator may begin to skip three of the quarterly leak detection periods for the valves in gas/vapor and liquid service and pumps in light liquid service.
d. If the percent of components leaking is greater than 2.0, the owner or operator shall comply with the requirements as described in LAC 33:III.2121.C but subsequently can again elect to use this Subsection.
e. The percent of components leaking shall be determined by dividing the sum of components found leaking during current monitoring and components for which repair has been delayed by the total number of components subject to the requirements of LAC 33:III.2121.C.
f. An owner or operator must keep a record of the percent of valves and pumps found leaking during each leak detection period.
2. Alternative Standards for Valves and Pumps - Increased Monitoring Frequency. If there is an excessive number of leaks (greater than the good performance level), then an increase in the frequency of monitoring may be required.
E. Recordkeeping
1. When a leak that cannot be repaired on-line and in-place, as described in LAC 33:III.2121.B is located, a weatherproof and readily visible tag bearing an identification number and the date the leak is located shall be affixed to the leaking component.

Where the provisions of this Section are effective, process units to which this Section applies that are also subject to the provisions of LAC 33:III.2121 will not be required to comply with the provisions of LAC 33:III.2121. Process units that are currently being monitored under LAC 33:III.2121 for fugitives shall be subject to the requirements of that rule until January 1, 1996.
3. Reserved.
4. The requirements of this Section shall be effective starting January 1, 1996.
5. This Section is applicable to sources in areas classified nonattainment for ozone and designated as moderate, severe, serious, or extreme as defined in the Clean Air Act Amendments of 1990 (Public Law 101-549).
6. Applicable facilities as defined in Subsection A.1 of this Section which are subject to New Source Performance Standards, LAC 33:III.3730 to 3749 (Subchapter VV), 4780 to 4783 (Subchapter GGG), 4820 to 4826 (Subchapter KKK), or 5171 (Subchapter V) may become exempt from this Section by:
a. submitting a written notice to the administrative authority* informing them of the facility's request to become exempt from LAC 33:III.2122 and how LAC 33:III.3730 to 3749 (Subchapter VV), 4780 to 4783 (Subchapter GGG), 4820 to 4826 (Subchapter KKK), or 5171 (Subchapter V) will be administered to obtain that exemption;
b. applying LAC 33:III.3730 to 3749 (Subchapter VV), 4780 to 4783 (Subchapter GGG), 4820 to 4826 (Subchapter KKK), or 5171 (Subchapter V) to leak limitations specified in Subsection C.1 of this Section rather than 10,000 ppm as specified in LAC 33:III.3730 to 3749 (Subchapter VV), 4780 to 4783 (Subchapter GGG), 4820 to 4826 (Subchapter KKK), or 5171 (Subchapter V);
c. including connectors as leak sources monitored and repaired using the restrictions in LAC 33:III.3730 to 3749 (Subchapter VV), 4780 to 4783 (Subchapter GGG), 4820 to 4826 (Subchapter KKK), or 5171 (Subchapter V) which apply to valves, and

B. Definitions. Terms in this Section are used as defined in LAC 33:III.111 with the exception of those terms specifically defined below.
Connector -- flanged, screwed, or other joined fittings used to connect two pipe lines or a pipe line and a piece of equipment. Welded connections are not connectors.
Good Performance Level -- an operating level reached when no more than 2.0 percent of a component in VOC service in a process unit are leaking at the leak rate definition or greater as determined by LAC 33:III.6077 (Reference Method 21, "Determination of Volatile Organic Compound Leaks").
Heavy Liquid Service -- equipment that is not in VOC gas/vapor service or is not in VOC light liquid service.
Inaccessible Valve/Connector -- a valve/connector that cannot be monitored without elevating the monitoring personnel more than two meters above a support surface.
In Vacuum Service -- equipment operating at an internal pressure that is at least 20 inches of water (38 mm of Hg) below ambient pressure.
Light Liquid -- a fluid with a vapor pressure greater than 0.3 kPa (0.0435 psia) at 20 degrees C (68 degrees F) or a fluid for which the weight percent evaporation at 150 degrees C exceeds 10 percent as determined by ASTM D86.
Light Liquid Service -- equipment in liquid service contacting a fluid greater than 10 percent by weight light liquid.
Liquid Service -- equipment which processes, transfers, or contains a VOC or mixture of VOC in the liquid phase.
Process Unit -- a process unit that can operate independently if supplied with sufficient feed or raw materials and sufficient storage facilities for the product.
Process Unit Shutdown -- a work practice or operational procedure that stops production from a process unit or part of a process unit during which it is technically feasible to clear process material from a process unit or part of a process unit consistent with safety constraints and during which repairs can be effected. An unscheduled work practice or operational procedure that stops production from a process unit or part of a process unit for less than 24 hours is not a process unit shutdown. An unscheduled work practice or operational procedure that would stop production from a process unit or part of a process unit for a shorter period of time than would be required to clear the process unit or part of the process unit of materials and start-up the unit, and would result in greater emissions than delay of repair of leaking components until the next scheduled process unit shutdown, is not a process unit shutdown. The use of spare equipment and technically feasible bypassing of equipment without stopping production are not process unit shutdowns.
Unrepairable Component -- unrepairable components are those designated as requiring a process unit shutdown to repair where more emissions would be created by an immediate facility shutdown than allowing the component to leak until the next scheduled shutdown, and the component is listed on a shutdown list for repairs.
C. Fugitive Emission Control Requirements
1. Leak Limitations
a. No component in petroleum refineries, SOCMI, MTBE, and polymer manufacturing industry shall be allowed to leak volatile organic compounds exceeding an instrument reading of 1,000 ppmv or greater for valves, connectors, pressure relief devices, process drains, and open-ended valves and lines; 5,000 ppmv for pumps and compressors; or 10,000 ppmv for agitators as outlined in Subsection D of this Section, when tested by LAC 33:III.6077.
b. No component in natural gas processing plants shall be allowed to leak volatile organic compounds exceeding an instrument reading off of 2,500 ppmv for valves, connectors, pressure relief devices, process drains, and open-ended valves and lines; 5,000 ppmv for pumps and compressors; or 10,000 ppmv for agitators as outlined in Subsection D of this Section, when tested by LAC 33:III.6077.
c. Any regulated component observed leaking by sight, sound, or smell must be repaired according to Subsection C.3 of this Section, regardless of the leak's concentration. This includes flange and connection leaks found per Subsection D.3.b of this Section, pump and compressor seal leaks found during the weekly visual inspections, and any other regulated component found leaking.
2. No valve, except safety pressure relief valves, shall be located at the end of a pipe or line containing volatile organic compounds unless the end of such line is sealed with a second valve, a blind flange, a plug, or a cap. Such sealing devices may be removed only when the line is in use, for example, when a sample is being taken. When the line has been used and is subsequently resealed, the upstream valve shall be closed first, followed by the sealing device.
3. The operator shall make every reasonable effort to repair a leaking component, as described in this Subsection, within 15 days. If the component cannot be isolated or bypassed so as to significantly reduce or eliminate leakage, or if the repair of a component would require a unit shutdown, and if the shutdown would create more emissions than the repair would eliminate, the repair may be delayed to the next scheduled shutdown. The delay of repair shall not be any later than the next scheduled process unit shutdown. An early unit shutdown may be ordered if the total percentage of leaking and unrepairable components are excessive. 4. Percent of leaking components at a process unit shall be determined for a test period as follows:
Clv
% Clvp = ------- * 100% Eq. 1
Ctv
where:
% Clvp = percent of a leaking components, where the component is the classification of valves or pumps.
Clv = number of valves or pumps found leaking during the monitoring period.
Ctv = total number of valves or pumps monitored during the period.
5. Total percent of leaking and unrepairable components shall be determined as follows:
Ctlv
% Ctlvp = ------------ * 100% Eq. 2
Cttv + Ctuvp
where:
Percent Ctlvp = total percent of leaking and unrepairable valves or pumps.
Ctlv = number of valves or pumps found leaking or defined as unrepairable.
Cttv = total number of valves or pumps tested during the period.
Ctuvp = total number of valves or pumps which were defined as unrepairable.
D. Monitoring Requirements. The monitoring of the affected components shall be performed by the following schedule using the method described in Subsection C of this Section or one of the alternate monitoring programs in Subsection E of this Section.
1. Petroleum Refineries, SOCMI, MTBE, and Polymer Manufacturing Industry
a. Monitor with a leak detection device one time per year (annually) the following items:

b. Monitor immediately with a leak detection device any component that appears to be leaking on the basis of sight, smell, or sound. In lieu of monitoring, the operator may elect to implement actions as specified in Subsection C of this Section.
c. Inaccessible valves shall be monitored on an annual basis at a minimum,
d. Unsafe-to-monitor valves and connectors shall be monitored when conditions would allow these valves and connectors to be monitored safely (e.g., during shutdown).
4. Exemptions. Monitoring is not required on the following:
a. components subject to Subsection D.1 of this Section (petroleum refineries, SOCMI, MTBE, and polymer manufacturing industry) which contact a process fluid that contains less than 10 percent VOC by volume or components subject to Subsection D.2 of this Section (natural gas processing plants) which contact a process fluid that contains less than 1.0 percent VOC by weight;
b. components in the petroleum refineries, SOCMI, MTBE, and polymer manufacturing industry that contact only a process liquid containing a VOC having a true vapor pressure equal to or less than 0.3 kPa (0.0435 psia) at 20 degrees C (68 degrees F).
c. pressure relief valves in liquid service at SOCMI and polymer manufacturing industry, except after venting;

k. components that have been placed on a shutdown list for repairs are exempt from further monitoring until a repair has been attempted.
5. Alternate Monitoring Program. Any facility that already has in place a fugitive emission monitoring program which controls to a higher degree than required under this Section shall be exempted from this Section upon submittal of a description of the program to the administrative authority* and approval thereof.
E. Alternate Control Techniques. The monitoring schedule in Subsection D of this Section may be modified as follows:
1. Alternate Standards for Valves subject to Subsection D.1.b or D.2.b of this Section - Skip Period Leak Detection and Repair.
a. An owner or operator may elect to comply with one of the alternative work practices specified in Subsection E.1.b, c, g, or 2 of this Section. However, the administrative authority* must be notified in writing before implementing one of the alternative work practices.
b. After two consecutive quarterly leak detection periods with the percent of leaking valves (Eq. 1) equal to or less than 2.0, an owner or operator may begin to skip one of the quarterly leak detection periods for the valves in gas/vapor and light liquid service.
c. After five consecutive quarterly leak detection periods with the percent of leaking valves (Eq. 1) equal to or less than 2.0, an owner or operator may begin to skip three of the quarterly leak detection periods for the valves in gas/vapor and light liquid service.
d. If the percent of leaking valves (Eq. 1) is greater than 2.0, or the total percent of leaking and unrepairable valves (Eq. 2) is greater than 4.0, the owner or operator shall comply with the requirements as described in Subsection D of this Section but subsequently can again elect to use this Subsection when the requirements are met.
e. The percent of leaking valves (Eq. 1) shall be determined by dividing the sum of components found leaking during the current monitoring period by the total number of valves which were tested and multiplying the results by 100 percent.
f. An owner or operator must keep a record of the percent of valves found leaking during each leak detection period and the total percentage of leaking and unrepairable valves.
g. Existing equipment that has been monitored under LAC 33:III.2121 for fugitives at the leak definition of 10,000 ppmv can initially elect to use this alternate standard if the unit has data documented by January 1, 1996, with the department that indicates the percent of leaking valves (Eq. 1) is less than or equal to 2.0 percent leak rate at 10,000 ppmv for the required time period.
2. Alternative Standards for Valves - Increased Monitoring Frequency. If the percent of leaking valves (Eq. 1) in a test period is greater than 2.0, or the total percent of leaking and unrepairable valves (Eq. 2) is greater than 4.0, then an increase in the frequency of monitoring may be required by the administrative authority*.
3. Alternate Standard for Batch Processes. As an alternate to complying with the requirements in Subsection D of this Section an owner or operator of a batch process in VOC service may elect to comply with one of the following alternative work practices. The batch product-process equipment shall be tested with a gas using the procedures specified in Subsection E.3.a of this Section or with a liquid as specified in Subsection E.3.b of this Section.
a. The following procedures shall be used to pressure test batch product-process equipment using a gas (e.g., air or nitrogen) to demonstrate compliance.
i. The batch product-process equipment train shall be pressurized with a gas to the operating pressure of the equipment. The equipment shall not be tested at a pressure greater than the pressure setting of the lowest relief valve setting.
ii. Once the test pressure is obtained, the gas source shall be shut off.
iii. The test shall continue for not less than 15 minutes unless it can be determined in a shorter period of time that the allowable rate of pressure drop was exceeded. The pressure in the batch product-process equipment shall be measured after the gas source is shut off and at the end of the test period. The rate of change in pressure in the batch product-process equipment shall be calculated using the following equation:
P (Pf - Pi)
- = --------- Eq. 5
t (tf - ti)
where:
P/t = change in pressure, psia/hr.
Pf = final pressure, psia.
Pi = initial pressure, psia.
tf - ti = elapsed time, hours.
iv. The pressure shall be measured using a pressure measurement device (gauge, manometer, or equivalent) which has a precision of ±2.5 millimeters (±0.05 psig) of mercury in the range of test pressure and is capable of measuring pressures up to the relief set pressure of the pressure relief device.
v. A leak is detected if the rate of change in pressure is greater than 6.9 kPa (1 psig) in one hour or if there is visible, audible, or olfactory evidence of fluid loss.
b. The following procedures shall be used to pressure test batch product-process equipment using a liquid to demonstrate compliance.
i. The batch product-process equipment train, or section of the train, shall be filled with the test liquid (e.g., water, alcohol). Once the equipment is filled, the liquid source shall be shut off.
ii. The test shall be conducted for a period of at least 60 minutes, unless it can be determined in a shorter period of time that the test is a failure.
iii. Each seal in the equipment being tested shall be inspected for indications of liquid dripping or other indications of fluid loss. If there are any indications of liquids dripping or of fluid loss, a leak is detected.
iv. If a leak is detected, it shall be repaired and the batch product-process equipment shall be retested before VOCs are fed to the equipment.
v. If the batch product-process equipment fails the retest or the second of two consecutive pressure tests, it shall be repaired as soon as practicable, but not later than 30 calendar days after the equipment is placed in VOC service.
F. Recordkeeping
1. When a component which has a leak that cannot be repaired, as described in Subsection C of this Section, is located, a weatherproof and readily visible tag bearing an identification number and the date the leak is located shall be affixed to the leaking component. After the leak has been repaired the tag identifying the component as a leaking component may be removed.
2. A survey log shall be maintained by the operator and shall include the following:
a. the name of the process unit where the leaking component is located;
b. the name of the leaking component;
c. the stream identification at the leak;
d. the identification number from the tag required by Subsection F.1 of this Section;
e. the date the leak was located;
f. the date maintenance was performed;
g. the date(s) the component was rechecked after maintenance, as well as the instrument reading(s) upon recheck (For natural gas processing plants the soap bubble test commonly performed in the industry is satisfactory.);
h. a record of leak detection device calibration;
i. a list of leaks not repaired until turnaround;
j. a list of total number of items checked versus the total found leaking.
3. The operator shall retain the survey log for two years after the latter date specified in Subsection F.2 of this Section and make said log available to the administrative authority* upon request.
G. Reporting Requirements. The operator of the affected facility shall, after each quarterly monitoring has been performed, submit a report listing all leaks that were located but not repaired within the 15-day limit along with a demonstration of achieving good performance level. These reports are due by the last day of January, April, July, and October. For units complying with the alternate control techniques a report shall be submitted by the last day of the month following the quarter that monitoring was performed. Such reports shall include the following:
1. the name of the unit where the leaking component is located and the date of last unit shutdown;
2. the name of the leaking component;
3. the stream identification at the leak;
4. the date the leak was located;
5. the date maintenance was attempted;
6. the date the leak will be repaired if the component is awaiting a shutdown;
7. the reason repairs failed or were postponed;
8. the list of items awaiting turnaround for repair;
9. the number of items checked versus the number found leaking;
10. the percent of components leaking for the test period;
11. the total percent of leakers;
