Emissions and electrical production monitoring, recordkeeping and reporting requirements under Part II.









(1) Monitoring and recordkeeping requirements. For all baseload electric generation facilities or units and baseload electric cogeneration facilities or units subject to WAC 173-407-120, 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.
(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 173-407-120, producing 25 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) For baseload electric generation facilities or units and baseload electric cogeneration facilities or units subject to WAC 173-407-120 producing less than 25 MW of electricity, the owner or operator may either utilize 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, or use 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.
(C) 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.
(D) 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).
(A) For baseload electric generation facilities or units or baseload electric cogeneration facilities or units subject to WAC 173-407-120 producing 25 MW or more of electricity, N2O emissions shall be determined as follows:
(I) 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.
(II) 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.
(B) For baseload electric generation facilities or units or baseload electric cogeneration facilities or units subject to WAC 173-407-120 producing less than 25 MW of electricity, the annual N2O emissions will be 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.
(iv) Methane (CH4).
(A) For baseload electric generation facilities or units or baseload electric cogeneration facilities or units subject to WAC 173-407-120 producing 25 MW or more of electricity, CH4 emissions shall be determined as follows:
(I) 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.
(II) 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.
(B) For baseload electric generation facilities or units or baseload electric cogeneration facilities or units subject to WAC 173-407-120 producing less than 25 MW of electricity. The annual CH4 emissions will be 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.
(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 ecology for ecology approval. Upon request and submission of appropriate documentation of fuel heat content variability, ecology 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 ecology. 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 173-407-120 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, ecology 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 ecology and the permitting authority 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 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. The report may be an Excel™ 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.
