PDF173-407-050

Calculating total carbon dioxide emissions to be mitigated under Part I.

(1) Step 1 - Calculate the annual CO2 emission rate. Calculate the annual CO2 emission rate using the following formula unless a differing analysis is necessary or appropriate for the electric generating process and type of equipment:
CO2rate
=
Fs × Ks
× Ts +
F1 × K1
× T1 +
F2 × K2
× T2 +
F3 × K3
× T3 … +
Fn × Kn
× Tn
2204.6
2204.6
2204.6
2204.6
2204.6
where:
CO2rate
=
Annual CO2 emission rate in metric tons per year
F1 to Fn
=
Maximum design fuel firing rate in MMBtu/hour calculated as manufacturer or designer's guaranteed total net station generating capability in MWe/hour times the new equipment heat rate in MMBtu/MWe. Determined based on higher heating values of fuel
K1 to Kn
=
Fuel to CO2 conversion factor for the fuel(s) being evaluated in lb CO2/MMBtu for fuel F1 to Fn
T1 to Tn
=
Hours per year fuel F1 to Fn is allowed to be used. The default is 8760 hours unless there is a limitation on hours in an order of approval
Fs
=
Maximum design supplemental fuel firing rate in MMBtu/hour, at higher heating value of the fuel
Ks
=
Fuel to CO2 conversion factor for the supplemental fuel being evaluated in lb CO2/MMBtu for fuel Fs given fuel
Ts
=
Hours per year supplemental fuel Fs is allowed. The default is 8760 hours unless there is a limitation on hours in an order of approval
(a) When there are multiple new fossil-fueled electric generating units, the above calculation must be performed for each unit and the annual CO2 emission rate of all units must be summed.
(b) A unit or facility allowed to use multiple fuels must use the maximum allowed hours on the highest CO2 producing fuels for each fuel until the total of all hours per fuel add up to the allowable annual hours.
(c) A new unit or facility allowed to use multiple fuels without restriction in its order of approval must perform this calculation assuming that the fuel with the highest CO2 emission rate is used 100 percent of the time.
(d) When the order of approval restricts the annual operating hours for any reason, the total of T1 to Tn equals the annual allowable hours of operation in the order of approval.
(e) Fuel to CO2 conversion factors. For K1 to Kn and Ks in the formula in subsection (1) of this section, use the CO2 emission factors for fossil fuels in 40 C.F.R. Part 98, Table C-1 (in effect on the date in WAC 173-407-006), except that the values for nonfossil fuels must be 0.00 lb/MMBtu.
(2) Step 2 - Determine the total carbon dioxide emissions. You must use the following formula to determine total carbon dioxide emissions:
Total CO2 Emissions = CO2rate × 30 × 0.6
where:
CO2rate
=
Annual CO2 emission rate in metric tons per year
30
=
Thirty-year period
0.6
=
Assumed capacity factor
(3) Step 3 - Determine the cogeneration credit (if any).
(a) Where the cogeneration unit or facility qualifies for cogeneration credit, the cogeneration credit is the annual CO2 emission rate (in metric tons per year). You must use the following formula or a similar method to determine the annual CO2 cogeneration credit:
CO2credit
=
Hs
× (Ka) ÷ n
2204.6
where:
CO2credit
=
The annual CO2 cogeneration credit in metric tons/year
Hs
=
Annual heat energy supplied by the cogeneration plant to the "steam host" per the contract or other binding obligation/agreement between the parties in MMBtu/yr as substantiated by an engineering analysis
Ka
=
The time weighted fuel to CO2 conversion factor for the cogeneration plant in lb CO2/MMBtu supplied. The time weighted average is calculated similarly to the above method described in subsection (1) of this section
n
=
Efficiency of new boiler that would provide the same quantity of thermal energy. Assume n = 0.85 unless facility provides information supporting a different value
(b) Calculate the metric tons of the cogeneration credit over the thirty-year period.
Cogeneration Credit = CO2credit × 30
(4) Step 4 - Determine the mitigation quantity. Determine the CO2 emissions mitigation quantity using the following formula:
Mitigation Quantity = Total CO2 Emissions × 0.2 - Cogeneration Credit
where:
Mitigation quantity
=
The total CO2 emissions to be mitigated in metric tons
0.2
=
The mitigation factor in RCW 80.70.020(4)
(5) Additional restrictions for a modification to an existing facility not involving installing new generating units. Calculate the CO2 mitigation quantity using the method in subsections (1) through (4) of this section with the following restrictions:
(a) The quantity of CO2 subject to mitigation is limited to the emissions resulting from the modification and does not include the emissions occurring prior to the modification;
(b) An increase in operating hours or other operational limitations established in an order of approval is not an exempt modification under this regulation. However, only emissions related to the increase in operating hours are subject to the CO2 mitigation program requirements;
(c) The annual CO2 emission rate (CO2rate) in subsection (1) of this section is the difference between the premodification condition and the postmodification condition, but using the like new heat rate for the combustion equipment; and
(d) A facility may use a cogeneration credit only if it is a new cogeneration credit established after July 1, 2004.
[Statutory Authority: Chapter 80.70 RCW. WSR 18-05-091 (Order 16-12), § 173-407-050, filed 2/21/18, effective 3/24/18. Statutory Authority: Chapter 80.80 RCW.

Carbon dioxide mitigation plan requirements and options under Part I.

(1) Mitigation plan requirements.
(a) The facility must mitigate the quantity of CO2 emissions determined by WAC 173-407-050 (4) or (5) as applicable. The facility must have an approved CO2 mitigation plan as part of the order of approval. The facility does not need to submit any mitigation plan if the calculated mitigation quantity is less than or equal to zero.
(b) The facility must implement the mitigation plan based on the schedule in the order of approval. A facility may request an extension of the schedule by submitting a written request to the permitting authority before applicable deadline(s). The request must propose a revised schedule and document why the facility needs more time to implement the mitigation plan.
(2) Mitigation plan options. An applicant for a fossil-fueled thermal electric generation facility must include one or a combination of the following CO2 mitigation options as part of its mitigation plan:
(a) Payment to a third party to provide mitigation;
(b) Direct purchase of permanent carbon credits; or
(c) Investment in applicant-controlled CO2 mitigation projects, including combined heat and power (cogeneration).
(3) Requirements of the payment to a third-party option.
(a) The initial mitigation rate is $1.60 per metric ton of CO2 to be mitigated. For a cogeneration plant, the monetary amount is based on the difference between twenty percent of the total carbon dioxide emissions and the cogeneration credit. This rate will change when EFSEC adjusts it through the process described in RCW 80.70.020 (5)(a) and (b).
Total payment amount = Mitigation rate × Mitigation quantity
(b) An applicant may choose between a lump sum payment and partial payments over a period of five years.
(i) The applicant must pay the lump sum payment amount to the independent qualified organization no later than one hundred twenty days after the start of commercial operation.
(ii) The applicant must make partial payments to the independent qualified organization in five equal payments over five years. The applicant must pay the first twenty percent of the total payment to the independent qualified organization no later than one hundred twenty days after the start of commercial operation. An applicant must make a payment of the same amount (or an adjusted amount if the rate is changed under RCW 80.70.020 (5)(a)) by the anniversary date of the initial payment for the next four consecutive years. The facility must provide a letter of credit or comparable security for the remaining 80 percent at the time of the first payment. The letter of credit or comparable security must include possible rate changes.
(4) Requirements of the permanent carbon credits option. The applicant must acquire permanent carbon credits equaling the mitigation quantity as calculated in WAC 173-407-050(4), unless the power plant permanently ceases operation. The permanent carbon credits must meet the following criteria:
(a) Credits must derive from real, verified, permanent, and enforceable CO2 or CO2 equivalents emission mitigation not otherwise required by statute, regulation, or other legal requirements;
(b) The credits must be acquired after July 1, 2004;
(c) The credits may not have been used for other CO2 mitigation projects; and
(d) The credits purchased for CO2 mitigation must not be resold unless approved by the permitting authority. The permitting authority must determine the permanent carbon credits proposed for resale are offset by other CO2 mitigation method(s). Facilities that cease operation may sell their carbon credits without replacement.
(5) Applicant controlled mitigation projects option. The facility may invest directly in mitigation projects. The permitting authority cannot require the direct investment cost of the applicant controlled mitigation project, including funds used for selection, monitoring, and evaluation of mitigation projects, to exceed the cost of the total payment to a third party per WAC 173-407-060(3).
The applicant controlled mitigation project must be:
(a) Conducted directly by or under the control of the order of approval holder.
(b) Approved by the permitting authority and included as a condition of the order of approval.
(c) Operational within one year after the start of commercial operation. Failure to implement an approved mitigation plan is subject to enforcement under WAC 173-407-080.
(d) The order of approval holder may not use more than twenty percent of the total funds for the selection, monitoring, and evaluation of mitigation projects, and the management and enforcement of contracts.

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) Use the representative heat content for the fuel instead of the periodic monitoring of heat content.
(vi) Facility owner or operator must test renewable fuel heat content monthly or with a different frequency approved by ecology. The facility owner or operator must base the different frequency on the variability of the heat content of the renewable fuel.
(A) If a facility or unit using a mixture of renewable and fossil fuels does not adjust their GHG emissions by accounting for the heat input from renewable fuels, ecology does not require monitoring of the heat content of the renewable fuels.
(B) Upon request and with appropriate documentation, ecology may allow a source to use representative heat content for the renewable fuel instead of the periodic monitoring of heat content required above.
(vii) Facility owner or operator must test the heat content of renewable fuel feedstocks monthly or on a different schedule approved by ecology. Ecology will approve the different schedule based on the variability of the heat content of the renewable fuel feedstocks. The facility owner or operator must measure the heat content of the fuel feedstocks in the form they are used in the combustion process.
(A) If a facility or a unit using a mixture of renewable and fossil fuels and does not adjust their GHG emissions by accounting for the heat input from renewable fuels, ecology does not require monitoring of the heat content of the renewable fuel feedstocks.
(B) Upon request and with supporting documentation, ecology may allow a source to use representative heat content for the renewable fuel feedstock instead of the periodic monitoring of heat content required above.
(2) Reporting requirements. Facility owner or operator must report the results of the monitoring required by this section to ecology and the permitting authority annually.
(a) Facility or unit subject to the reporting requirements of 40 C.F.R. Part 75. Facility owner or operator must report annual emissions of CO2, N2O and CH4 that occurred in the previous calendar year and supporting information to ecology and the permitting authority by January 31st of each calendar year. The facility owner or operator may submit the report as an Excel™ or CSV format copy of the report submitted to EPA per 40 C.F.R. Part 75 with N2O and CH4 emissions appended to the report.
(b) Facility or unit not subject to the reporting requirements of 40 C.F.R. Part 75.

Requirements for nongeologic permanent sequestration plans and sequestration programs under Part II.

A baseload electric generation facility or unit or baseload electric cogeneration facility or unit that is subject to Part II and Part III of this chapter and proposes to use nongeologic sequestration of GHG to meet the GHG EPS must submit a sequestration plan or sequestration program for approval to ecology.
(1) A sequestration plan and sequestration program for nongeologic sequestration of GHG must include:
(a) Financial requirements. As a condition of plant operation, each owner or operator of a facility or unit must provide letters of credit sufficient to ensure successful implementation, closure, and post-closure activities identified in the sequestration plan or sequestration program.
(i) The owner or operator of a proposed sequestration project must establish a letter of credit to cover all expenses for construction and operation of necessary equipment, and any other significant costs. The owner or operator must revise the cost estimate for the sequestration project annually to include any changes in the project and cost changes due to inflation.
(ii) Closure and post-closure financial assurances. The owner or operator must establish a closure and a post-closure letter of credit to cover all closure and post-closure expenses, respectively. The owner or operator must designate ecology or EFSEC, as appropriate, as the beneficiary to carry out the closure and post-closure activities. The value of the closure and post-closure accounts must cover all costs of closure and post-closure care identified in the closure and post-closure plan. The owner or operator must revise the closure and post-closure cost estimates annually to include any changes in the sequestration project and cost changes due to inflation. The obligation to maintain the account for closure and post-closure care survives the termination of any permits and the cessation of injection. The requirement to maintain the closure and post-closure accounts is enforceable regardless of whether the requirement is a specific condition of the permit.
(b) The application for approval of a sequestration plan or sequestration program must include, but is not limited to, the following:
(i) A current site map showing the boundaries of the permanent sequestration project containment system(s) and all areas where the system(s) will store GHG.
(ii) A technical evaluation of the proposed project, including but not limited to, the following:
(A) The name of the area in which the sequestration will take place;
(B) A description of the facility or unit and place of GHG containment system(s);
(C) A complete site description including, but not limited to, the terrain, the geology, the climate (including rain and snowfall expected), and any land use restrictions that exist at the time of the application or the applicant will place on the site in the future;
(D) The proposed calculated maximum quantity of sequestered GHG and areal extent of the location where the facility will store GHG using a method acceptable to and filed with ecology; and
(E) Evaluation of the quantity of sequestered GHG and their physical or chemical forms that may escape from the containment system(s) at the proposed project.
(iii) A public safety and emergency response plan for the proposed project. The plan must detail the safety procedures concerning the sequestration project containment system and residential, commercial, and public land use within one mile, or as necessary to identify potential impacts, of the outside boundary of the project area.
(iv) A GHG loss detection and monitoring plan for all parts of the sequestration project. The approved GHG loss detection and monitoring plan must address identification of potential release to the atmosphere.
(v) A detailed schedule of annual benchmarks for sequestration of GHG.
(vi) A closure and post-closure plan.
(vii) Any other information that ecology deems necessary to make its determination.
(c) Monitoring plan. In order to monitor the effectiveness of the implementation of the sequestration plan or sequestration program, the owner or operator must submit a detailed monitoring plan that will ensure detection of failure of the GHG sequestration method to place the GHG into a sequestered state. The monitoring plan must be sufficient to provide reasonable assurance that the sequestration provided by the project meets the definition of permanent sequestration. The monitoring must continue for the longer of twenty years beyond the end of GHG placement of the greenhouse gases into a sequestration containment system, or twenty years beyond the date determined by ecology that all of the GHG have achieved a state that they are now stably sequestered in that environment.
(d) If the sequestration plan or sequestration program fails to sequester GHG as provided in the plan or program, the owner or operator of the baseload electric generation facility or unit or baseload electric cogeneration facility or unit is no longer in compliance with the GHG EPS.
(2) Public notice and comment. Ecology must provide public notice and a public comment period before approving or denying any sequestration plan or sequestration program.
(a) Public notice. Ecology will make a public notice only after the owner or operator of the facility submits all information required by ecology and ecology makes all applicable preliminary determinations. The owner or operator of the facility or unit must pay the cost of providing public notice. Public notice must include analyses of the effects on the local, state and global environment in the case of failure of the sequestration plan or sequestration program. The owner or operator of the facility must make the sequestration plan or sequestration program available for public inspection in at least one location near the proposed project.
(b) Public comment period.
(i) The public comment period must be thirty days or longer as specified in the public notice.
(ii) The public comment period must extend through the hearing date.
(iii) Ecology must make no final decision on any sequestration plan or sequestration program until the public comment period has ended and ecology has considered all comments received during the public comment period.
(c) Public hearing(s).
(i) Ecology must hold a public hearing within the public comment period. Ecology will determine the location, date, and time of the public hearing.
(ii) Ecology must provide at least thirty days prior notice of the hearing on a sequestration plan or sequestration program.

Enforcement of the emissions performance standard under Part II.

Note:
Ecology is the agency responsible for enforcing this section.
(1) A baseload electric generation facility or unit or baseload electric cogeneration facility or unit subject to WAC 173-407-130 that fails to meet the applicable GHG EPS or any implementation schedules and requirements in a sequestration plan or program may be subject to enforcement using the enforcement criteria and procedures specified in chapter 70.94 RCW.
Penalties can include:
(a) Financial penalties, which may be assessed after a failure to meet a sequestration benchmark in the sequestration plan or sequestration program. Each pound of GHG above the GHG EPS will constitute a separate violation, as averaged on an annual basis;
(b) Revocation of the approval to construct the source or to operate the source.
(2) If a new, modified or upgraded facility or unit fails to meet a sequestration plan or sequestration program benchmark on schedule, a revised sequestration plan or sequestration program must be submitted no later than one hundred fifty calendar days after the due date established under subsection (3)(c) of this section for reporting the failure. The revised sequestration plan or sequestration program must be submitted to ecology for approval.
(3) Provisions for unavoidable circumstances.
(a) The owner or operator of a facility or unit operated under an approved sequestration plan or sequestration program shall have the burden of proving to ecology in an enforcement action that failure to meet a sequestration benchmark was unavoidable. This demonstration must be a condition to obtain relief under (d), (e), and (f) of this subsection.
(b) Failure to meet a sequestration benchmark determined to be unavoidable under the procedures and criteria in this section must be excused and not subject to financial penalty.
(c) Failure to meet a sequestration benchmark must be reported as part of the routine sequestration monitoring reports or by January 31st of the year following the calendar year during which the event occurred. Upon request by ecology, the owner or operator of the sequestration project must submit a full written report including the known causes, the corrective actions taken, and the preventive measures to be taken to minimize or eliminate the chance of recurrence.
(d) Failure to meet a sequestration benchmark due to startup or shutdown conditions must be considered unavoidable provided the source reports as required under (c) of this subsection. The owner or operator of the sequestration project must adequately demonstrate that the failure to meet a sequestration benchmark could not be prevented through careful planning and design and if a bypass of equipment occurs, and the bypass is necessary to prevent loss of life, personal injury, or severe property damage.
(e) Failure to meet a sequestration benchmark due to scheduled maintenance must be considered unavoidable if the source reports as required under (c) of this subsection, and adequately demonstrates that the excess emissions could not be avoided through reasonable design, better scheduling for maintenance or through better operation and maintenance practices.
(f) Failure to meet a sequestration benchmark due to upsets must be considered unavoidable provided the source reports as required under (c) of this subsection, and adequately demonstrates that:
(i) The event was not caused by poor or inadequate design, operation, maintenance, or any other reasonably preventable condition;
(ii) The event was not of a recurring pattern that indicated inadequate design, operation, or maintenance; and
(iii) The owner or operator took immediate and appropriate corrective action in a manner consistent with good practice for minimizing nonsequestration during the upset event.
(4) Enforcement for permit violations. Enforcement of a violation of an order of approval must follow the requirements of chapter 70.94 RCW, as implemented by the permitting authority. Enforcement of an ecology approved sequestration plan or sequestration program must be in accordance with this section.

Procedures for determining compliance with the emissions performance standard of a long-term financial commitment under Part II.

(1) A baseload generation facility or unit or baseload cogeneration facility or unit in a long-term financial commitment must meet the GHG EPS in WAC 173-407-130 in effect at the time the parties sign the commitment.
(2) A long-term financial commitment must meet the following conditions to comply with the GHG EPS in WAC 173-407-130:
(a) Electricity from unspecified sources is limited to 12 percent of the total electricity in a long-term financial commitment.
(b) Long-term financial commitments with the Bonneville power administration are exempt from meeting the GHG EPS.
(c) For a long-term financial commitment with multiple power plants, each specified power plant named in the long-term financial commitment must individually meet the GHG EPS in WAC 173-407-130 in effect on the date the parties sign the commitment. Ecology deems a power plant named in a long-term financial commitment with multiple power plants meeting the following criteria to be in compliance with the GHG EPS:
(i) A facility or unit powered exclusively by renewable resources;
(ii) A facility or unit that is designed and intended to use a renewable fuel to provide at least 90 percent of its total annual heat input;
(iii) A baseload electric cogeneration facility or unit, fueled by natural gas or waste gas or a combination of the two fuels, that was in operation before June 30, 2008, unless it has:
(A) Changed ownership; or
(B) Upgraded.
(3) If ecology cannot determine compliance with the GHG EPS for a long-term financial commitment based on the conditions in subsection (2) of this section, ecology must use procedures in WAC 173-407-140 or 173-407-150 to determine compliance with the GHG EPS. All reports required by WAC 173-407-140(2) or 173-407-150(5) must be sent to ecology. An investor-owned electric utility must send another copy of the reports to UTC. A consumer owned electric utility must send another copy of the reports to their governing board.
(4) This rule exempts long-term purchase of coal transition power from meeting the GHG EPS as long as the term of the long-term purchase meets the schedule in RCW 80.80.040 (3)(c).
(5) In determining if a long-term financial commitment complies with the EPS, all unspecified power will have an emission rate of 2,300 lb/MWh.
