Subpart GGGa VOC Monitoring Report
Table Notes
1 - Existing compressors in ALKY, COGEN, DDU, and N2C units were constructed prior to November 7,2006. Tesoro has not conducted any
construction, modification, or reconstruction activities that would trigger GGGa applicability for these compressors; however due to the Utah
State lmplementation Plan Section lX, Part H.1 1 (gxiv) all affected equipment is required to comply with the provisions of 60.590a to 60.593a
no later than January 1,2016. The Utah SIP was adopted by the Air Quality Board on December 2,2015.
2 - Excluding those valves designated for no detectable emissions under the provisions of S60.482-7a(0,
3 - Excluding those pumps designated for no detectable emissions under the provisions of $60.482-2a(e) and those pumps complying with
560.a82-2a(0.
4 - Excluding those compressors designated for no detectable emissions under the provisions of 560.482-3a(i), S60.482-3a(h), and
60.593a(bX1). Tesoro demonstrates compressors are in hydrogen service per 60.593a(b)(3)(i).
5 - Process unit shutdown means a work practice or operational procedure that stops production from a process unit or part of a process unit
during wtrich 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 accomplished. The following are not considered process unit shutdowns:
(a) 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.
(b) 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 lhe 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.
(c) The use of spare equipment and technically feasible bypassing of equipment without stopping production.
6 - For leaking components that remain in VOC service the delay of repair designation will be removed once two consecutive monthly
moniloring instrument readings are below the leak definition.
7 - Component changes involving CLVS, PRVs, Heavy Liquids, or a Process Unit switch do not show up as "added'or'removed' because
they have been in service; only the component class or Unit identifier has been changed.
