Current through Register Vol. 24-18, September 15, 2024
(1) Monitoring and recordkeeping requirements. For all baseload electric generation facilities or units and baseload electric cogeneration facilities or units subject to WAC 463-85-120, the following parameters shall be monitored and reported as explained below:
(a) Electrical output: Electrical output as measured at the
point of connection with the local electrical distribution network or
transmission line, as appropriate. Measurement will be on an hourly or daily
basis and recorded in a form suitable for use in calculating compliance with
the greenhouse gases emissions performance standard;
(b) Useful thermal energy output: Quantity of energy supplied
to nonelectrical production uses determined by monitoring both the energy
supplied and the unused energy returned by the thermal energy user or uses. The
required monitoring can be accomplished through:
(i) Measurement of the mass, pressure, and temperature of the
supply and return streams of the steam or thermal fluid; or
(ii) Use of thermodynamic calculations as approved by
ecology.
(iii) Measurements will be on an hourly or daily basis and
recorded in a form suitable for use in calculating compliance with the
greenhouse gases emissions performance standard; and
(c) Regulated greenhouse gases emissions.
(i) The regulated greenhouse gases emissions are the emissions
of regulated greenhouse gases from the main plant exhaust stack and any bypass
stacks or flares. For baseload electric generation facilities or units and
baseload electric cogeneration facilities or units utilizing
CO2 controls and sequestration to comply with the
greenhouse gases emissions performance standard, direct and fugitive
CO2 emissions from the CO2
separation and compression process are included.
(ii) Carbon dioxide (CO2).
(A) For baseload electric generation facilities or units and
baseload electric cogeneration facilities or units subject to WAC
463-85-120, producing 350 MW or
more of electricity, CO2 emissions will be monitored by
a continuous emission monitoring system meeting the requirements of 40 C.F.R. Sections 75.10 and 75.13 and 40 C.F.R. Part 75 Appendix F. If allowed by the
requirements of 40 C.F.R. Part 72, a facility may estimate
CO2 emissions through fuel carbon content monitoring and
methods meeting the requirements of 40 C.F.R. Sections 75.10 and 75.13 and 40 C.F.R. Part 75 Appendix G.
(B) When the monitoring data from a continuous emission
monitoring system does not meet the completeness requirements of 40 C.F.R. Part
75, the baseload electric generation facility operator or operator will
substitute data according to the process in 40 C.F.R. Part 75.
(C) Continuous emission monitors for CO2
will be installed at a location meeting the requirements of 40 C.F.R. Part 75,
Appendix A. The CO2 and flow monitoring equipment must
meet the quality control and quality assurance requirements of 40 C.F.R. Part
75, Appendix B.
(iii) Nitrous oxide (N2O). For baseload
electric generation facilities or units or baseload electric cogeneration
facilities or units subject to WAC
463-85-120 producing 350 MW or
more of electricity, N2O emissions shall be determined
as follows:
(A) For the first year of operation, N2O
emissions are estimated by use of emission factors as published by the
Environmental Protection Agency, the federal Department of Energy's Energy
Information Agency, or other authoritative source as approved by ecology for
use by the facility.
(B) For succeeding years, N2O emissions
will be estimated through use of generating unit specific emission factors
derived through use of emissions testing using ecology or Environmental
Protection Agency approved methods. The emission factor shall be derived
through testing N2O emissions from the stack at varying
loads and through at least four separate test periods spaced evenly throughout
the first year of commercial operation.
(iv) Methane (CH4). For baseload
electric generation facilities or units or baseload electric cogeneration
facilities or units subject to WAC
173-407-120 producing 350 MW or
more of electricity, CH4 emissions shall be determined
as follows:
(A) For the first year of operation, CH4
emissions are estimated by use of emission factors as published by the
Environmental Protection Agency, the federal Department of Energy's Energy
Information Agency, or other authoritative source as approved by ecology for
use by the facility.
(B) For succeeding years, CH4 emissions
will be estimated through use of plant specific emission factors derived
through use of emissions testing using ecology or Environmental Protection
Agency approved methods. The emission factor shall be derived through testing
CH4 emissions from the stack at varying loads and
through at least four separate test periods spaced evenly through the first
year of commercial operation.
(d) Fuel usage and heat content information.
(i) Fossil fuel usage will be monitored by measuring continuous
fuel volume or weight as appropriate for the fuel used. Measurement will be on
an hourly or daily basis and recorded in a form suitable for use in calculating
greenhouse gases emissions.
(ii) Renewable energy fuel usage will be monitored by measuring
continuous fuel volume or weight as appropriate for the fuel used. Measurement
will be on an hourly or daily basis and recorded in a form suitable for use in
calculating greenhouse gases emissions.
(iii) Heat content of fossil fuels shall be tested at least
once per calendar year. The owner or operator of the baseload electric
generation facility or unit shall submit a proposed fuel content monitoring
program to EFSEC for EFSEC's approval. Upon request and submission of
appropriate documentation of fuel heat content variability, EFSEC may allow a
source to:
(A) Test the heat content of the fossil fuel less often than
once per year; or
(B) Utilize representative heat content for the renewable
energy source instead of the periodic monitoring of heat content required
above.
(iv) Renewable energy fuel heat content will be tested monthly
or with a different frequency approved by EFSEC. A different frequency will be
based on the variability of the heat content of the renewable energy
fuel.
(A) If the baseload electric generation facilities or units or
baseload electric cogeneration facilities or units subject to WAC
463-85-120 using a mixture of
renewable and fossil fuels do not adjust their greenhouse gases emissions by
accounting for the heat input from renewable energy fuels, monitoring of the
heat content of the renewable energy fuels is not required.
(B) Upon request and with appropriate documentation, EFSEC may
allow a source to utilize representative heat content for the renewable energy
source instead of the periodic monitoring of heat content required
above.
(2) Reporting requirements. The results of the monitoring required by this section shall be reported to EFSEC and ecology annually.
(a) Facilities or units subject to the reporting requirements
of 40 C.F.R. Part 75 . Annual emissions of CO2,
N2O and CH4 will be reported to
ecology and EFSEC by January 31 of each calendar year for emissions that
occurred in the previous calendar year. The report may be an
ExcelTM or CSV format copy of the report submitted
to EPA per 40 C.F.R. Part 75 with the emissions for N2O
and CH4 appended to the report.
(b) For facilities or units not subject to the reporting
requirements of 40 C.F.R. Part 75, annual emissions of
CO2, N2O and
CH4 and supporting information will be reported to
ecology and the air quality permitting authority with jurisdiction over the
facility by January 31 of each calendar year for emissions that occurred in the
previous calendar year.
