The National Emission Standards for
Hazardous Air Pollutants (NESHAP) for Petroleum Refineries,
Catalytic Cracking Units, Catalytic Reforming Units, and Sulfur
Recovery Units (40 CFR part 63, subpart UUU) apply to three types
of affected sources at major source petroleum refineries. The three
affected sources are: the fluid catalytic cracking unit catalyst
regeneration; the catalytic reforming unit catalyst regeneration;
and the sulfur recovery unit. The rule also includes requirements
for by-pass lines associated with the three affected sources. New
facilities include those that commenced construction or
reconstruction after the date of proposal. EPA is finalizing
amendments to subpart UUU to revise the operating standards for
fluid catalytic cracking units and clarify the requirements for
catalytic reforming units and sulfur recovery units. The potential
respondents are owners or operators of any existing or new
petroleum refinery facilities. Emission points affected by the
final amendments to subpart UUU are fluid catalytic cracking unit
catalyst regeneration, catalytic reforming catalyst regeneration,
and sulfur recovery units. Significant changes include new testing
requirements and more stringent operating limits for fluid
catalytic cracking unit catalyst regeneration, revisions to
requirements for catalytic reforming catalyst regeneration when
using active purging, and the addition of an alternative emissions
limit for sulfur recovery units using oxygen enriched air. Other
significant changes include new electronic reporting requirements
for performance test reporting and revised monitoring requirements.
An overarching change to all NESHAP regulations is a change in
policy with regards to emission requirements and associated
monitoring, recordkeeping, and reporting during startup, shutdown,
and malfunctions. These changes include new emission limits for
startup and shutdown for fluid catalytic cracking unit catalyst
regeneration and sulfur recovery units. This information is being
collected to assure compliance with 40 CFR part 63, subpart
UUU.
