Current through Register Vol. 48, No. 38, September 20, 2024
a) The owner or operator of an EGU complying
with this Subpart B by means of Section
225.230(a)(1)(B);
using input mercury levels (Ii) and complying by means
of Section
225.230(b)
or (d) or Section
225.232;
electing to comply with the emissions testing, monitoring, and recordkeeping
requirements under Section
225.239;
demonstrating compliance under Section
225.233,
except an EGU in an MPS Group that elects to comply with the emission standard
in Section
225.233(d)(1)(A)
or (d)(2)(A); or demonstrating compliance
under Sections
225.291
through
225.299,
except an EGU in a CPS Group that elects to comply with the emission standard
in Section
225.294(c)(1)
or that opts into the emission standard in Section
225.294(c)(1)
pursuant to Section
225.294(e)(1)
or that has permanently ceased combusting coal must fulfill the following
requirements:
1) Perform sampling of the coal
combusted in the EGU for mercury content. The owner or operator of such EGU
must collect a minimum of one 2-lb. grab sample from the belt feeders anywhere
between the crusher house or breaker building and the boiler or, in cases in
which a crusher house or breaker building is not present, at a reasonable point
close to the boiler of a subject EGU, according to the schedule in subsections
(a)(1)(A) through (C). The sample must be taken in a manner that provides a
representative mercury content for the coal burned on that day. If multiple
samples are tested, the owner or operator must average those tests to arrive at
the final mercury content for that time period. The owner or operator of the
EGU must perform coal sampling as follows:
A)
EGUs complying by means of Section 225.233, except an EGU in an MPS Group that
elects to comply with the control efficiency standard in Section
225.233(d)(1)(B)
or (d)(2)(B) or elects to comply with Section
225.233(d)(4),
or Sections
225.291
through 225.299, except an EGU in a CPS Group that elects to comply with the
control efficiency standard in Section
225.294(c)(2)
or that opts into the emission standard in Section
225.294(c)(2)
pursuant to Section
225.294(e)(1)
must perform such coal sampling at least once per month unless the boiler did
not operate or combust coal at all during that month;
B) EGUs complying by means of the emissions
testing, monitoring, and recordkeeping requirements under Section
225.239
or Section
225.233(d)(4),
or EGUs that opt into the emission standard in Section
225.294(c)(2)
pursuant to Section
225.294(e)(1)(B),
must perform such coal sampling according to the schedule provided in Section
225.239(e)(3)
of this Subpart;
C) All other EGUs
subject to this requirement, including EGUs in an MPS or CPS Group electing to
comply with the control efficiency standard in Section
225.233(d)(1)(B)
or (d)(2)(B), Section
225.294(c)(2),
or Section
225.294(c)(2)
pursuant to Section
225.294(e)(1)(A),
must perform such coal sampling on a daily basis when the boiler is operating
and combusting coal.
2)
Analyze the grab coal sample for the following:
A) Determine the heat content using ASTM
D5865-04 or an equivalent method approved in writing by the Agency.
B) Determine the moisture content using ASTM
D3173-03 or an equivalent method approved in writing by the Agency.
C) Measure the mercury content using ASTM
D6414-01, ASTM D3684-01, ASTM D6722-01, or an equivalent method approved in
writing by the Agency.
3) The owner or operator of multiple EGUs at
the same source using the same crusher house or breaker building may take one
sample per crusher house or breaker building, rather than one per
EGU.
4) The owner or operator of an
EGU must use the data analyzed pursuant to subsection (b) of this Section to
determine the mercury content in terms of parts per million.
b) The owner or operator of an EGU
that must conduct sampling and analysis of coal pursuant to subsection (a) of
this Section must begin such activity by the following date:
1) If the EGU is in daily service, at least
30 days before the start of the month for which such activity will be
required.
2) If the EGU is not in
daily service, on the day that the EGU resumes operation.
