Current through Register Vol. 48, No. 38, September 20, 2024
Except as otherwise provided in 35 Ill. Adm. Code
724.101,
the owner or operator of a facility that has process vents to which Subpart AA
of 35 Ill. Adm. Code 724 applies must provide the following additional
information:
a) For facilities that
cannot install a closed-vent system and control device to comply with Subpart
AA of 35 Ill. Adm. Code 724 on the effective date on which the facility becomes
subject to that Subpart or Subpart AA of 35 Ill. Adm. Code 725, an
implementation schedule, as specified in 35 Ill. Adm. Code
724.933(a)(2).
b) Documentation of compliance with the
process vent standards in 35 Ill. Adm. Code
724.932,
including the following:
1) Information and
data identifying all affected process vents, annual throughput and operating
hours of each affected unit, estimated emission rates for the affected vent and
for the overall facility (i.e., the total emissions for all affected vents at
the facility), and the approximate location within the facility of each
affected unit (e.g., identify the hazardous waste management units on a
facility plot plan);
2) Information
and data supporting estimates of vent emissions and emission reduction achieved
by add-on control devices based on engineering calculations or source tests.
For the purpose of determining compliance, estimates of vent emissions and
emission reductions must be made using operating parameter values (e.g.,
temperatures, flow rates, or concentrations) that represent the conditions that
exist when the waste management unit is operating at the highest load or
capacity level reasonably expected to occur; and
3) Information and data used to determine
whether or not a process vent is subject to 35 Ill. Adm. Code
724.932.
c) Where an
owner or operator applies for permission to use a control device other than a
thermal vapor incinerator, catalytic vapor incinerator, flare, boiler, process
heater, condenser, or carbon adsorption system to comply with 35 Ill. Adm. Code
724.932, and chooses to use test data to determine the organic removal
efficiency or the total organic compound concentration achieved by the control
device, a performance test plan as specified in 35 Ill. Adm. Code
724.935(b)(3).
d) Documentation of compliance with 35 Ill.
Adm. Code 724.933, including the following:
1) A list of all information references and
sources used in preparing the documentation.
2) Records, including the dates of each
compliance test required by 35 Ill. Adm. Code
724.933(k).
3) A design analysis, specifications,
drawings, schematics, piping, and instrumentation diagrams based on the
appropriate sections of "APTI Course 415: Control of Gaseous Emissions", USEPA
publication number EPA-450/2-81-005, incorporated by reference in 35 Ill. Adm.
Code
720.111(a),
or other engineering texts approved by the Agency that present basic control
device information. The design analysis must address the vent stream
characteristics and control device parameters as specified in 35 Ill. Adm. Code
724.935(b)(4)(C).
4) A statement signed and dated by the owner
or operator certifying that the operating parameters used in the design
analysis reasonably represent the conditions that exist when the hazardous
waste management unit is or would be operating at the highest load or capacity
level reasonably expected to occur.
5) A statement signed and dated by the owner
or operator certifying that the control device is designed to operate at an
efficiency of 95 weight percent or greater, unless the total organic emission
limits of 35 Ill. Adm. Code
724.932(a)
for affected process vents at the facility can be attained by a control device
involving vapor recovery at an efficiency less than 95 weight
percent.
