Hi Cortney, 

I've attached a revised preamble/rule in redline and a clean version. Please take a look and let me know 

if 

you think we need to have another phone call to discuss things. 

If you think another call is needed, please let me know your availability as soon as possible so I can get 

something on the calendar. 

In place of the ambient monitoring, a few specific work practices have been laid out in the regulatory 

text. Feel free to give me a call if you have any questions about these. 

Thanks, look forward to hearing from you.

records the actual volumetric flow rate through each separately 

ducted hood; or install, calibrate, maintain, and operate a 

monitoring device that continuously records the volumetric flow 

rate at the control device inlet of each exhaust system 

ventilating the building. The flow rate monitoring device(s) can 

be installed in any location in the exhaust duct such that 

reproducible flow rate monitoringmeasurements will result. The 

flow rate monitoring device(s) shallmust have an accuracy of 

plus or minus 10 percent over itsthe normal process operating 

range and shallmust be calibrated according to manufacturer's 

instructions.

 (2) If a CEMS used to measure lead emissions is applicable, 

the owner or operator must install a CERMS with a sensor in a 

location that provides representative measurement of the exhaust 

gas flow rate at the sampling location of the CEMS used to 

measure lead emissions, taking into account the manufacturer’s 

recommendations. The flow rate sensor is that portion of the 

system that senses the volumetric flow rate and generates an 

output proportional to that flow rate.

 (i) The CERMS must be designed to measure the exhaust gas 

flow rate over a range that extends from a value of at least 20 

percent less than the lowest expected exhaust flow rate to a 

value of at least 20 percent greater than the highest expected 

exhaust gas flow rate. 
 (ii) The CERMS must be equipped with a data acquisition and 

recording system that is capable of recording values over the 

entire range specified in paragraph (b)(2)(i) of this section. 

 (iii) Each owner or operator must perform an initial 

relative accuracy test of the CERMS in accordance with the 

applicable Performance Specification in Appendix B to part 60 of 

the chapter.

record data during all periods of operation of the affected 

facility including periods of startup, shutdown, and 

malfunction, except for periods of monitoring system 

malfunctions, repairs associated with monitoring system 

malfunctions, and required monitoring system quality assurance 

or quality control activities (including, as applicable, 

calibration checks and required zero and span adjustments.

 (3) Each owner or operator must calculate the lead emissions 

rate in tons per year by summing all hours of CEMS data for a 

year to determine compliance with §63.1543 (b).

 (i) When the CERMS are unable to provide quality assured 

data the following applies: 

 (A) When data are not available for periods of up to 48 

hours, the highest recorded hourly emission rate from the 

previous 24 hours must be used.

 (B) When data are not available for 48 or more hours, the 

maximum daily emission rate based on the previous 30 days must 

be used.

§63.1551 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 40 CFR 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 shall not be available for 

claims for injunctive relief.

 (a) To establish the affirmative defense in any action to 

enforce such a limit, you must timely meet the notification 

requirements in paragraph (b) of this section, and must prove by 

a preponderance of evidence that:

 (1) The excess emissions:

 (i) 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 

 (ii) Could not have been prevented through careful planning, 

proper design or better operation and maintenance practices; and

 (iii) Did not stem from any activity or event that could 

have been foreseen and avoided, or planned for; and 

 (iv) Were not part of a recurring pattern indicative of 

inadequate design, operation, or maintenance; and 

 (2) Repairs were made as expeditiously as possible when the 

applicable emission limitations were being exceeded. Off-shift 

and overtime labor were used, to the extent practicable to make 

these repairs; and 
 (3) 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 

 (4) 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 

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

the excess emissions on ambient air quality, the environment and 

human health; and 

 (6) All emissions monitoring and control systems were kept 

in operation if at all possible, consistent with safety and good 

air pollution control practices; and 

 (7) All of the actions in response to the excess emissions 

were documented by properly signed, contemporaneous operating 

logs; and 

 (8) At all times, the facility was operated in a manner 

consistent with good practices for minimizing emissions; and 

 (9) 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 

shall also specify, using best monitoring methods and 

engineering judgment, the amount of excess emissions that were 

the result of the malfunction.

(b) Notification. The owner or operator of the facility 

experiencing an exceedance of its emission limit(s) during a 

malfunction shall notify the Administrator by telephone or 

facsimile (FAX) transmission as soon as possible, but no later 

than two business days after the initial occurrence of the 

malfunction, if it wishes to avail itself of an affirmative 

defense to civil penalties for that malfunction. The owner or 
operator seeking to assert an affirmative defense shall also 

submit a written report to the Administrator within 45 days of 

the initial occurrence of the exceedance of the standards in 

this subpart to demonstrate, with all necessary supporting 

documentation, that it has met the requirements set forth in 

paragraph (a) of this section. 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.
