assuming such duties.
B.
For Class I and II waste combustors:
(1)
within six months of the initial start-up of a waste combustor unit, all chief
facility operators and shift supervisors shall have obtained full
certification, or have scheduled the exam appropriate to the certification
being sought as described in part
7011.1281; and
(2) notwithstanding subitem (1), individuals,
if assuming the duties of chief facility operator or shift supervisor after six
months after the initial start-up of a waste combustor unit, shall obtain full
certification as described in part
7011.1281 within six months of
assuming such duties.
Subp. 2.
Particulate matter control
device operating temperature.
The inlet gas stream to each particulate matter control
device on a waste combustor as measured by part
7011.1260, subpart
4, item A, shall have a
temperature of no greater than 30 degrees Fahrenheit above the highest
four-hour arithmetic mean temperature measured during four consecutive hours
for this gas stream during the most recent performance test for polychlorinated
dibenzo-p-dioxins and polychlorinated dibenzofurans that demonstrated
compliance, except as allowed in items A and B.
A. For Class A, C, and II waste combustors,
during the annual PCDD/PCDF performance test and the two weeks preceding the
annual PCDD/PCDF performance test, no particulate matter control device
temperature limitations are applicable.
B. For Class A, C, and II waste combustors,
the commissioner shall waive the particulate matter control device temperature
limits for the purpose of evaluating system performance, testing new technology
or control technologies, diagnostic testing, or related activities for the
purpose of improving facility performance or advancing the state-of-the-art for
controlling facility emissions, provided a written notification is submitted to
the commissioner 30 days prior to undertaking any of the activities identified
in this item, with the following information:
(1) a description of the proposed project,
and the outcome the project is designed to evaluate;
(2) how the project conforms with the
activities described in this subpart for which the temperature limit can be
waived; and
(3) the length of time
the project will take to complete.
The commissioner shall approve the waiving of the particulate
matter control device operating temperature limits provided that the project
conforms with the activities described in this subpart for which the
temperature limit can be waived, and the project can be accomplished within 14
days.
Subp.
3.
Start-up on waste prohibited.
During start-up from a cold furnace, auxiliary fuels shall be
used to achieve combustion chamber operating temperature. The use of solid
waste solely to provide thermal protection of the grate or hearth during the
start-up period when solid waste is not being fed to the grate is not
considered to be continuous burning.
Subp. 4. [Repealed, 22 SR 1975]
Subp. 5.
Range of operation.
No owner or operator of a waste combustor shall operate the
waste combustor while combusting solid waste at a level above 110 percent of
the maximum demonstrated capacity of the combustion system, except as allowed
in items A and B, without conducting a performance test under part
7011.1265, which demonstrates
compliance with the emission limitations of part
7011.1225 at greater than 110
percent of the maximum demonstrated capacity.
A. For Class A, C, and II waste combustors,
during the annual PCDD/PCDF performance test and the two weeks preceding the
annual PCDD/PCDF performance test, no waste combustor maximum demonstrated
capacity is applicable.
B. For
Class A, C, and II waste combustors, the commissioner shall waive the maximum
demonstrated capacity limit for the purpose of evaluating system performance,
testing new technology or control technologies, diagnostic testing, or related
activities for the purpose of improving facility performance or advancing the
state-of-the-art for controlling facility emissions, provided a written
notification is submitted to the commissioner 30 days prior to undertaking any
of the activities identified in this item, with the following information:
(1) a description of the proposed project,
and the outcome the project is designed to evaluate;
(2) how the project conforms with the
activities described in this subpart for which the maximum demonstrated
capacity limit can be waived; and
(3) the length of time the project will take
to complete.
The commissioner shall approve the waiving of the maximum
demonstrated capacity limits provided that the project conforms with the
activities described in this subpart for which the operating capacity limit can
be waived, and the project can be accomplished within 14 days.
Subp. 6.
[Repealed, 22 SR 1975]
Subp. 7.
Dumpstack use and reporting requirements.
The dumpstack of a waste combustor must not be used for
conducting routine inspection or maintenance on the control equipment or the
combustion system without prior approval of the commissioner.
A dumpstack shall only be used at a waste combustor when
plant or worker safety would be in jeopardy without its use.
The owner or operator of a waste combustor shall record in
the daily operating record required in part
7011.1285, subpart
2, the date of use of the
dumpstack, the length of time the dumpstack was used, the operating conditions
of the waste combustor during dumpstack use, and the reason for using the
dumpstack.
