Current through Register Vol. 49, No. 13, September 23, 2024
Subpart 1.
Applicability. The
owners or operators of an emissions unit subject to parts
7011.1291,
7011.1292,
7011.1293,
7011.1294, 7011.1295,
7011.1350,
7011.1355,
7011.1360, and
7011.1370 must comply with this
part.
Subp. 2.
Definitions.
The terms used in this part have the meanings given them in
this subpart.
A. "Accurate and valid
data" means data that provides the measurement of emissions of an air
contaminant from the incinerator or of operating parameters of a component of
the incinerator. For continuously monitored emissions, data is accurate and
valid immediately upon recording. For emissions for which a performance test is
conducted, data is accurate and valid 14 days after the incinerator owners or
operators receive the performance test report, unless the incinerator owners or
operators notify the commissioner in writing within the same 14 days that the
owners or operators can show reason for rejecting the data.
B. "Normal start-up" means the period of time
between the initial start-up of a new, modified, retrofitted, or reconstructed
emissions unit of an incinerator or an emissions unit of an incinerator that is
modified, retrofitted, or reconstructed to meet the requirements of parts
7011.1360 to
7011.1370 and the lesser of 60
days after achieving the maximum production rate at which the emissions unit
will operate or 180 days after initial start-up.
Subp. 3.
Exceedance of continuously
monitored emission limits.
If, after normal start-up, accurate and valid data results
collected from continuous emission monitors exceed emission limits established
in part
7011.1350, item B; 7011.1355,
subpart 2;
7011.1365; or 7011.1370, subpart
1, or in the permit for the
incinerator, the incinerator owner or operator must:
A. report the exceedance to the commissioner
as soon as reasonably possible, giving consideration to matters of plant or
worker safety or access to communications;
B. commence appropriate repairs or
modifications to return the incinerator to compliance within 72 hours of the
exceedance;
C. shut down the
incinerator if the modification or repairs cannot be completed within 72 hours
of the exceedance; and
D. when
repairs or modifications have been completed, demonstrate to the commissioner
that the incinerator is in compliance. Th e incinerator may be started up after
the owner or operator has notified the commissioner in writing of the date the
owner or ope rator plans to start up the incinerator. Notification must be
given at least 24 hours before resuming operation. Compliance is demonstrated
by providing to the commissioner written results from the continuous monitor
showing compliance with the emission limits.
Subp. 4.
Exceedance of emission limits
determined through performance testing.
A. If, after normal start-up, accurate and
valid data results of a performance test demonstrate an exceedance of an
emissions limit established in part
7011.1355, subpart
2; 7011.1365; or 7011.1370,
subpart 1, or
in the facility air emissions permit, the owners or operators of an incinerator
must:
(1) report the exceedance to the
commissioner according to part
7019.1000;
(2) undertake appropriate steps to return the
incinerator to compliance and demonstrate compliance within 60 days of the
initial report to the commissioner of the exceedance; and
(3) shut down the incinerator if the
commissioner determines that compliance has not been achieved within 60 days of
the initial report of exceedance.
B. If shutdown was required under item A,
subitem (3), the owner or operator may restart the incinerator under the
conditions specified by the commissioner. The owners or operators must notify
the commissioner in writing of the date on which the owners or operators plan
to start up and to begin compliance testing. Notification must be received at
least ten days in advance of the compliance test date.
