3. Serial Numbers for Allocated CO Allowances. When allocating CO allowances to, and recording them in, an account, the Department or its agent shall assign each CO allowance a unique identification number that includes digits identifying the year for which the CO allowance is allocated.

(e) Compliance.

1. Allowances Available for Compliance Deduction. CO allowances that meet the following criteria are available to be deducted in order for a CO2 budget source to comply with the CO requirements of 310 CMR 7.70(1)(e)3. for a control period or an interim control period.

a. The CO allowances, other than CO offset allowances, are of allocation years that fall within a prior control period, the same control period, or the same interim control period for which the allowances will be deducted.

b. The CO allowances are held in the CO budget source's compliance account as of the CO allowance transfer deadline for that control period or interim control period are transferred into the compliance account by a CO allowance transfer correctly submitted for recordation under 310 CMR 7.70(7)(a) by the CO2 allowance transfer deadline for that control period or interim control period.

c. For CO offset allowances, the number of CO offset allowances that are available to be deducted in order for a CO2 budget source to comply with the CO2 requirements of 310 CMR 7.70(1)(e)3. for a control period or interim control period may not exceed 3.3% of the CO2 budget source's CO2 emissions for that control period, or 3.3% of 0.50 times the CO2 budget source's emissions for an interim control period, as determined in accordance with 310 CMR 7.70(6) and (8); and

d. CO allowances that are not necessary for deductions for excess emissions for a prior control period under 310 CMR 7.70(6)(e)4.

2. Deductions for Compliance. Following the recordation, in accordance with 310 CMR 7.70(7)(b), CO allowance transfers submitted for recordation in the CO budget source's compliance account by the CO allowance transfer deadline for a control period or interim control period, the Department or its agent shall deduct CO allowances available under 310 CMR 7.70(6)(e)1. to cover the source's CO2 emissions (as determined in accordance with 310 CMR 7.70(8)) for the control period or interim control period, as follows:

a. Until the amount of CO allowances deducted equals the number of tons of total CO emissions (or 0.50 times the number of tons of total CO emissions for the interim control period), less any CO emissions attributable to the burning of eligible biomass or the production of useful net thermal energy, determined in accordance with 310 CMR 7.70(8), from all CO2 budget units at the CO2 budget source for the control period or interim control period; or

b. If there are insufficient CO allowances to complete the deductions in 310 CMR 7.70(6)(e)2.a., until no more CO2 allowances available under 310 CMR 7.70(6)(e)1. remain in the compliance account.

c. After making the deductions for compliance, the Department or its agent shall notify the CO authorized account representative if it believes that the CO budget source exceeded its CO2 budget emissions limitation.

3. Identification of Available CO Allowances by Serial Number; Default Compliance Deductions.

a. The CO authorized account representative for a source's compliance account may request that specific CO allowances, identified by serial number, in the compliance account be deducted for emissions or excess emissions for a control period or interim control period in accordance with 310 CMR 7.70(6)(e)2. or 4. Such identification shall be made in the compliance certification report submitted in accordance with 310 CMR 7.70(4)(a).

b. The Department or its agent shall deduct CO allowances for a control period or interim control period from the CO budget source's compliance account, in the absence of an identification or in the case of a partial identification of available CO allowances by serial number under 310 CMR 7.70(6)(e)3.a., in the following descending order:

i. First, subject to the relevant compliance deduction limitations under 310 CMR 7.70(6)(e)1.c. and 4.a., CO2 offset allowances. CO2 offset allowances shall be deducted in chronological order (i.e., CO2 offset allowances from earlier allocation years shall be deducted before CO offset allowances from later allocation years). In the event that some, but not all, CO offset allowances from a particular allocation year are to be deducted, CO offset allowances shall be deducted by serial number, with lower serial number allowances deducted before higher serial number allowances.

ii. Second, any CO allowances, other than CO offset allowances, that are available for deduction under 310 CMR 7.70(6)(e)1. CO2 allowances shall be deducted in chronological order (i.e., CO allowances from earlier allocation years shall be deducted before CO allowances from later allocation years). In the event that some, but not all, CO allowances from a particular allocation year are to be deducted, CO2 allowances shall be deducted by serial number, with lower serial number allowances deducted before higher serial number allowances.

4. Deductions for Excess Emissions.

a. After completing the procedures in 310 CMR 7.70(6)(e)2., the Department or its agent shall deduct from the CO2 budget source's compliance account a number of CO allowances, equal to three times the number of the source's excess emissions. In the event that a source has insufficient CO allowances to cover three times the number of the source's excess emissions, the source shall be required within 14 calendar days of receipt of notice by the Department or its agent to transfer sufficient allowances into its compliance account. No CO offset allowances may be deducted to account for the source's excess emissions.

b. Any CO2 allowance deduction required under 310 CMR 7.70(6)(e)4.a. shall not affect the liability of the owners and operators of the CO budget source or the CO units at the source for any fine, penalty, or assessment, or their obligation to comply with any other remedy, for the same violation, as ordered under applicable State law. In assessing fines, penalties or other obligations, each ton of excess emissions or excess interim emissions is a separate violation.

c. The propriety of the Department's determination that a CO budget source had excess emissions and the concomitant deduction of CO allowances from that CO budget source's account may be later challenged in the context of the initial administrative enforcement, or any civil or criminal judicial action, arising from or encompassing that excess emissions violation. The commencement or pendency of any administrative enforcement, or civil or criminal judicial action arising from or encompassing that excess emissions violation, shall not act to prevent the Department or its agent from initially deducting the CO allowances resulting from the Department's original determination that the relevant CO budget source has had excess emissions. Should the Department revise its determination of the existence or extent of the CO budget source's excess emissions either by a settlement or final conclusion of any administrative or judicial action, the Department shall act as follows.

i. In any instance where the Department's determination of the extent of excess emissions was too low, the Department shall take further action under 310 CMR 7.70(6)(e)4.a. and b. to address the expanded violation.

ii. In any instance where the Department's determination of the extent of excess emissions was too high, the Department shall distribute to the relevant CO2 budget source a number of CO2 allowances equaling the number of CO2 allowances deducted which are attributable to the difference between the original and final quantity of excess emissions. Should such CO2 budget source's compliance account no longer exist, the CO allowances shall be provided to a general account selected by the owner or operator of the CO2 budget source.

5. The Department or its agent shall record in the appropriate compliance account all deductions from such an account pursuant to 310 CMR 7.70(6)(e)2. and 4.

6. Action by the Department on Submissions.

a. The Department may review and conduct independent audits concerning any submission under the CO Budget Trading Program and make appropriate adjustments of the information in the submissions.

b. The Department may deduct CO allowances from or transfer CO allowances to a source's compliance account based on information in the submissions, as adjusted under 310 CMR 7.70(6)(e)6.a.

(f) Banking. Each CO allowance that is held in a compliance account or a general account shall remain in such account unless and until the CO allowance is deducted or transferred under 310 CMR 7.70(4)(b), (6)(e), (6)(g), or (7).

(g) Account Error.

1. The Department or its agent may, at its sole discretion and on its own motion, correct any error in any CO Allowance Tracking System account. Within ten business days of making such correction, the Department or its agent shall notify the CO authorized account representative for the account.

2. At any time the CO authorized account representative may notify the Department if it believes that a mistake has been made.

(h) Closing of General Accounts.

1. A CO authorized account representative of a general account may instruct the Department or its agent to close the account by submitting a statement requesting deletion of the account from the CO Allowance Tracking System and by correctly submitting for recordation under 310 CMR 7.70(7)(a) a CO allowance transfer of all CO allowances in the account to one or more other CO Allowance Tracking System accounts.

2. If a general account shows no activity for a period of one year or more and does not contain any CO allowances, the Department or its agent may notify the CO authorized account representative for the account that the account shall be closed in the CO Allowance Tracking System 30 business days after the notice is sent. The account shall be closed after the 30-day period unless before the end of the 30-day period the Department or its agent receives a correctly submitted transfer of CO allowances into the account under 310 CMR 7.70(7)(a) or a statement submitted by the CO authorized account representative demonstrating to the satisfaction of the Department or its agent good cause as to why the account should not be closed. The Department or its agent will have sole discretion to determine if the owner or operator of the unit demonstrated that the account should not be closed.

(7) CO Allowance Transfers.

(a) Submission of CO Allowance Transfers. The CO authorized account representative who is the transferor shall submit the transfer to the Department or its agent. To be considered correctly submitted, the CO allowance transfer shall include the following elements in a format specified by the Department or its agent:

1. The numbers identifying both the transferor and transferee accounts;

2. A specification by serial number of each CO allowance to be transferred;

3. The printed name and signature of the CO authorized account representative of the transferor account and the date signed;

4. The date of the completion of the last sale or purchase transaction for the allowance, if any; and

5. The purchase or sale price of the allowance that is the subject of a sale or purchase transaction under 310 CMR 7.70(7)(a)4.

(b) Recordation.

1. Within five business days of receiving a CO2 allowance transfer, except as provided in 310 CMR 7.70(7)(b)2., the Department or its agent shall record a CO allowance transfer by moving each CO allowance from the transferor account to the transferee account as specified by the request, provided that:

a. The transfer is correctly submitted under 310 CMR 7.70(7)(a); and

b. The transferor account includes each CO allowance identified by serial number in the transfer.

2. A CO allowance transfer into or out of a compliance account that is submitted for recordation following the CO allowance transfer deadline and that includes any CO allowances that are of allocation years that fall within a control period prior or interim control period or the same as the control period or interim control period to which the CO allowance transfer deadline applies shall not be recorded until after completion of the process pursuant to 310 CMR 7.70(6)(e)2.

3. Where a CO allowance transfer submitted for recordation fails to meet the requirements of 310 CMR 7.70(7)(b)1., the Department or its agent shall not record such transfer.

1. Notification of Recordation. Within five business days of recordation of a CO allowance transfer under 310 CMR 7.70(7)(b), the Department or its agent shall notify each party to the transfer. Notice shall be given to the CO authorized account representatives of both the transferor and transferee accounts.

2. Notification of Non-recordation. Within ten business days of receipt of a CO allowance transfer that fails to meet the requirements of 310 CMR 7.70(7)(b)1., the Department or its agent shall notify the CO authorized account representatives of both accounts subject to the transfer of:

a. A decision not to record the transfer; and

b. The reasons for such non-recordation.

3. Nothing in 310 CMR 7.70(7) shall preclude the submission of a CO allowance transfer for recordation following notification of non-recordation.

(8) Monitoring and Reporting.

(a) General Requirements. The owners and operators, and to the extent applicable, the CO authorized account representative of a CO2 budget unit, shall comply with the monitoring, recordkeeping and reporting requirements as provided in 310 CMR 7.70(8) and all applicable sections of 40 CFR Part 75. Where referenced in 310 CMR 7.70(8), the monitoring requirements of 40 CFR Part 75 shall be adhered to in a manner consistent with the purpose of monitoring and reporting CO2 mass emissions pursuant to 310 CMR 7.70.

The diagram should indicate where the net electric output is measured and should include all electrical inputs and outputs to and from the CO budget source. If net electric output is determined using a billing meter, the diagram should show each billing meter used to determine net sales of electricity and should show that all electricity measured at the point of sale is generated by the CO2 budget units.

ii. If the CO budget unit monitors net thermal output, the diagram should include all steam or hot water coming into the net steam system, including steam from CO2 budget units and non-CO2 budget units, and all exit points of steam or hot water from the net steam system. In addition, each input and output stream shall have an estimated temperature, pressure and phase indicator, and an enthalpy in Btu/lb. The diagram of the net steam system should identify all useful loads, house loads, parasitic loads, any other steam loads and all boiler feedwater returns. The diagram shall represent all energy losses in the system as either usable or unusable losses. The diagram shall also indicate all flow meters, temperature or pressure sensors or other equipment used to calculate gross thermal output. If a sales agreement is used to determine net thermal output, the diagram should show the monitoring equipment used to determine the sales of steam.

b. A description of each output monitoring system. The description of the output monitoring system shall include a written description of the output system and the equations used to calculate output. For net thermal output systems, descriptions and justifications of each useful load shall be included.

c. A detailed description of all quality assurance/quality control activities that will be performed to maintain the output system in accordance with 310 CMR 7.70(8)(h)5.

d. Documentation supporting any output value(s) to be used as a missing data value should there be periods of invalid output data. The missing data output value shall be either zero or an output value that is likely to be lower than a measured value and that is approved as part of the monitoring plan required under 310 CMR 7.70(8)(h)3.

4. Initial Certification. A certification statement shall be submitted by the CO authorized account representative stating that either the output monitoring system consists entirely of billing meters or that the output monitoring system meets one of the accuracy requirements for non-billing meters at 310 CMR 7.70(8)(h)4.b. The certification shall be submitted in accordance with the compliance deadlines established in 310 CMR 7.70(3)(b).

a. Billing Meters. The billing meter shall record the electric or thermal output. Any electric or thermal output values that the facility reports shall be the same as the values used in billing for the output. Any output measurement equipment used as a billing meter in commercial transactions requires no additional certification or testing.

b. Non-billing Meters. For non-billing meters and systems that include a mixture of billing meters and non-billing meters, the output monitoring system shall meet either of the accuracy criteria in 310 CMR 7.70(8)(h)4 i. and ii.

i. System Approach to Accuracy. The system approach to accuracy shall include a determination of how the system accuracy of within less than or equal to 10% of the reference value is achieved using the individual components in the system and should include data loggers and any wattmeters used to calculate the final net electric output data and/or any flowmeters for steam or condensate, temperature measurement devices, absolute pressure measurement devices, and differential pressure devices used for measuring thermal energy.

ii. Component Approach to Accuracy. If testing a piece of output measurement equipment shows that the output readings are not accurate to within less than or equal to 3.0% of the full scale value, then the equipment shall be repaired or replaced to meet that requirement. Data shall remain invalid until the output measurement equipment passes an accuracy test or is replaced with another piece of equipment that passes the accuracy test.

5. Ongoing QA/QC. The following ongoing quality assurance/quality control activities must be performed in order to maintain the output system:

a. Billing Meters. In the case where billing meters are used to determine output, no QA/QC activities beyond what are already performed are required.

b. Non-billing Meters. Certain types of equipment such as potential transformers, current transformers, nozzle and venturi type meters, and the primary element of an orifice plate only require an initial certification of calibration and do not require periodic recalibration unless the equipment is physically changed. However, the pressure and temperature transmitters accompanying an orifice plate shall require periodic retesting. For such pressure and temperature transmitters, and other types of equipment, either recalibrate or reverify the meter accuracy at least once every two years (i.e., every eight calendar quarters), unless a consensus standard allows for less frequent calibrations or accuracy tests. The output monitoring system shall either meet an accuracy of within 10% of the reference value, or each component monitor for the output system shall meet an accuracy of within 3.0% of the full scale value, whichever is less stringent. If testing a piece of output measurement equipment shows that the output readings are not accurate to within 3.0% of the full scale value, then the equipment should be repaired or replaced to meet that requirement.

c. Out-of-control Periods. If testing a piece of output measurement equipment shows that the output readings are not accurate to the certification value, data remain invalid until the output measurement equipment passes an accuracy test or is replaced with another piece of equipment that passes the accuracy test. All invalid data shall be replaced by either zero or an output value that is likely to be lower than a measured value and that is approved as part of the monitoring plan required under 310 CMR 7.70(8)(h)3.

6. Recordkeeping and Reporting.

a. General Provisions. The CO authorized account representative shall comply with all recordkeeping and reporting requirements in 310 CMR 7.70(8)(h) and with the requirements of 310 CMR 7.70(1)(e)5. and (2)(a)5.

b. Recordkeeping. Facilities shall retain data used to monitor, determine, or calculate net generation for ten years from the date reported.

c. Annual Reports. The CO authorized account representative shall submit annual output reports in a spreadsheet, as follows. The data shall be sent both electronically and in hardcopy by March 1st for the immediately preceding calendar year to the Department or its agent. The annual report shall include the annual total unit level MWh, the annual total useful steam output and a certification statement from the CO authorized account representative stating the following, "I am authorized to make this submission on behalf of the owners and operators of the CO budget sources or CO2 budget units for which the submission is made. I certify under penalty of law that I have personally examined, and am familiar with, the statements and information submitted in this document and all its attachments. Based on my inquiry of those individuals with primary responsibility for obtaining the information, I certify that the statements and information are to the best of my knowledge and belief true, accurate, and complete. I am aware that there are significant penalties for submitting false statements and information or omitting required statements and information, including the possibility of fine or imprisonment."

(i) CO Budget Units That Generate Useful Net Thermal Energy.

1. The CO authorized account representative of a combined heat and power CO budget source that generates useful net thermal energy shall report the following information for the combined heat and power CO budget source to the Department or its agent for each calendar quarter:

a. The total amount of useful net thermal energy output produced by CO2 budget units expressed in MMBtu, the total volume of steam output produced by CO2 budget units expressed in cubic feet, the average pressure of the steam output produced by CO2 budget units expressed in pounds per square inch, and the average temperature of the steam expressed in degrees Fahrenheit. The amount of useful net thermal energy output shall be determined in a manner as approved by the Department in the CO2 Budget Emission Control Plan consistent with the requirements of 310 CMR 7.70(3) and (8)(h).

b. The total amount of CO2 emissions from CO2 budget units attributable to the production of useful net thermal energy, in tons, calculated in accordance with 310 CMR 7.70(8)(i)2.

2. The quantity of CO2 emissions attributable to the production of useful net thermal energy shall be determined by the following equation (rounded to the nearest whole ton):

UNTE/.80 x 122 lb/MMBtu

2000 lb/ton

Where:

UNTE = useful net thermal energy (in MMBtu output) generated by CO2 budget units at the combined heat and power CO2 budget source during each calendar quarter.
