^aRefineries may choose to implement the modified HON equipment leaks standards as specified in 63.648 and in 40 CFR 63 subpart H instead of the 40 CFR 60 subpart VV program. The testing, monitoring, recordkeeping, and reporting requirements of subpart H are similar to subpart VV. See the regulation for details.
^bDoes not apply if pump, valve, or compressor is demonstrated by Method 21 to operate at <500 ppm above background. Also, compressors in hydrogen service are exempt.
^cMonitoring frequency is reduced with good performance.
^dThere is no specified monitoring frequency, but if a leak is observed by visual, audible, olfactory, or other means, it must be monitored and repaired.
^eThis requirement reflects a recent amendment (63 FR 44135) to the petroleum refineries NESHAP.
