Owners or operators of the affected
facilities described must make one-time-only notifications. Owners
or operators are also required to maintain records of the
occurrence and duration of any startup, shutdown, or malfunction in
the operation of an affected facility, or any period during which
the monitoring system is inoperative. Monitoring requirements
specific to equipment leaks of VOC in petroleum refineries provide
information on which components are leaking VOCs. NSPS Subpart GGG
references the compliance requirements of NSPS subpart VV, and NSPS
subpart GGGa references the compliance requirements of NSPS subpart
VVa. Owners or operators are required to periodically record
information identifying leaking equipment, repair methods used to
stop the leaks, and dates of repair. Semiannual reports are
required to measure compliance with the standards of NSPS Subparts
VV and VVa as referenced by NSPS subparts GGG and GGGa. These
notifications, reports, and records are essential in determining
compliance and are required, in general, of all sources subject to
NSPS. Any owner or operator subject to the provisions of this part
shall maintain a file of these measurements, and retain the file
for at least two years following the date of such measurements,
maintenance reports, and records.
The increase in burden from the
most-recently approved ICR is due to adjustments in Agency’s
estimates. For both Subpart GGG and Subpart GGGa, the burden has
increased due to more accurate estimates for recording operation
parameters and semiannual work practice reports. The most-recently
approved ICR underestimated the effort required to record operating
parameters and develop semiannual reports. Updated estimates for
these burden items increased the total respondent burden for
Subpart GGG from 18,800 to 130,000 hours and for Subpart GGGa from
6,120 to 53,400 hours. This ICR takes into account estimates
provided by consultations with industry trade associations. These
changes result in an overall increase in respondent and agency
burden for both Subparts.
