Pre-existing Engines

Groups

Marginal note:Establishment

  •  (1) For the purposes of sections 58 to 68, a responsible person for pre-existing engines that are regular-use and have a rated brake power of at least 250 kW establishes their group by designating which of those engines is to belong to the group.

  • Marginal note:One group

    (2) A responsible person may have at most one group.

  • Marginal note:Designation date

    (3) An engine is designated as belonging to a responsible person’s group as of

    • (a) the date on which the responsible person became an owner of the engine if, within 90 days after that date, they make a record that contains the following information:

      • (i) that date,

      • (ii) the engine’s serial number or, if the serial number is not known or cannot be obtained, the engine’s unique alphanumeric identifier,

      • (iii) the date on which the record was made, and

    • (b) in any other case, the date on which the responsible person makes a record that contains the following information:

      • (i) the engine’s serial number — or, if the serial number is not known or cannot be obtained, the engine’s unique alphanumeric identifier ,

      • (ii) the date on which the record was made, and

      • (iii) an indication that the engine belongs to the group.

  • Marginal note:Ceasing to belong

    (4) An engine that belongs to a responsible person’s group ceases to belong to the group if

    • (a) the engine ceases to be a regular-use engine; or

    • (b) the responsible person cancels its designation as belonging to their group by making a record of the engine’s serial number or, if the serial number is not known or cannot be obtained, the engine’s unique alphanumeric identifier , along with the date of the cancellation.

  • Marginal note:Deemed not belonging to any group

    (5) An engine that has been designated as belonging to more than one group is deemed not to belong to any group.

NOx Emission Intensity Limits

Marginal note:Engines not belonging to a group

 As of January 1, 2021, the NOx emission intensity of a pre-existing engine that is regular-use, has a rated brake power of at least 250 kW and does not belong to any group must not exceed the limit of 210 ppmvd15% or 4 g/kWh, whichever applies.

Marginal note:Engines belonging to a group after 2025

 Subject to section 60, as of January 1, 2026, the NOx emission intensity of an engine that belongs to a group must not exceed the limit of 210 ppmvd15% or 4 g/kWh, whichever applies.

Marginal note:Engines belonging to a group from 2021 to 2025

  •  (1) Subject to section 60, in the period that begins on January 1, 2021 and ends on December 31, 2025, within each group of engines there must be a subset of engines that has the following characteristics:

    • (a) the total rated brake power of the engines that belong to the subset is at least 50% of the total rated brake power of the engines that belong to the group; and

    • (b) the NOx emission intensity of each engine that belongs to the subset does not exceed the limit of 210 ppmvd15% or 4 g/kWh, whichever applies.

  • Marginal note:Ceasing to belong

    (2) For the purpose of paragraph (1)(a), even if an engine that has been registered under subsection 97(3) ceases to belong to the group, its rated brake power may be included in the total rated brake power of both the subset referred to in paragraph (1)(a) and the group.

Yearly Average NOx Emission Intensity Limits — on Election

Marginal note:After 2025 and from 2021 to 2025

 A responsible person who makes an election in accordance with subsection 61(1) to opt out of the application of section 58 or 59 must — for each year after 2020 that follows the making of the election — ensure that the yearly average NOx emission intensity of each subgroup that they establish under section 65 does not exceed the following limit:

  • (a) 210 ppmvd15% or 4 g/kWh, whichever applies, for years after 2025; or

  • (b) 421 ppmvd15% or 8 g/kWh, whichever applies, for the years 2021 to 2025.

Marginal note:Election

  •  (1) The responsible person must — by the October 31 immediately before the first year in respect of which the limit referred to in section 60 is to apply — make the election by providing the Minister with the following information for inclusion in the engine registry for each subgroup that they establish under section 65:

    • (a) the serial number — or, if the serial number is not known or cannot be obtained, the unique alphanumeric identifier — of each pre-existing engine and replacement unit that belongs to the subgroup; and

    • (b) each NOx emission value, if any, that is assigned under section 67 to a pre-existing engine, or a replacement unit that is a modern engine, that belongs to the subgroup.

  • Marginal note:Yearly average NOx emission intensity

    (2) The yearly average NOx emission intensity of a subgroup for a year is determined by the formula

    ΣiΣj(Eij ×Pi × Tij)/ΣiΣj(Pi × Tij)

    where

    Eij
    is the jth NOx emission value, expressed in ppmvd15% or g/kWh, assigned under subsection 66(1) or 67(1) to the ith engine or replacement unit that belongs to the subgroup;
    Pi
    is the rated brake power, expressed in kW, of the ith engine or replacement unit that belongs to the subgroup;
    Tij
    is — excluding any period referred to in section 49 —
    • (a) the number of hours during the year that the ith engine or replacement unit operated while it belonged to the subgroup and had an assigned NOx emission value of Eij, or

    • (b) the number of days during the year that the ith engine or replacement unit operated at any time during a day while it belonged to the subgroup and had an assigned NOx emission value of Eij, if Tij is determined under this paragraph for all the engines and replacement units that belong to the subgroup;

    i
    is the ith engine or replacement unit that belongs to the subgroup, where i goes from 1 to m and where m is the number of those engines and replacement units that belong to the subgroup; and
    j
    is the jth assignment under subsection 66(1) or 67(1) of a NOx emission value to the ith engine or replacement unit that belongs to the subgroup, where j goes from 1 to n and where n is the number of assignments of NOx emission values under those subsections to that engine or replacement unit during the year.
  • Marginal note:Number of hours

    (3) The number of hours during a year referred to in paragraph (a) of the description of Tij in subsection (2) must be determined

    • (a) by means of a non-resettable hour meter, or another non-resettable device, installed on the ith engine or replacement unit to take readings that are recorded along with the dates of the readings and the serial number — or, if the serial number is not known or cannot be obtained, the unique alphanumeric identifier — make and model of the engine within the shortest feasible period before or after

      • (i) January 1 of that year,

      • (ii) January 1 of the year after that year,

      • (iii) the date of any change in the NOx emission value assigned to the ith engine under subsection 66(1) or 67(1),

      • (iv) the date on which the ith engine or replacement unit is designated as belonging to the subgroup, and

      • (v) the date on which the ith engine or replacement unit ceases to belong to the group;

    • (b) by means of a log of operations used to make a record in respect of the ith engine or replacement unit at least once every 30 days during that year that contains

      • (i) data related to the number of hours that it has operated on each day since any previous record,

      • (ii) the dates of those days,

      • (iii) its make, model and serial number or, if the serial number is not known or cannot be obtained, unique alphanumeric identifier, and

      • (iv) the initials of the person making the record; or

    • (c) by means of a SCADA system used to make a record in respect of the ith engine or replacement unit at least once every 30 days during that year that contains

      • (i) data that is taken every 15 minutes and used to determine the number of hours that it has operated,

      • (ii) the dates on which that data was taken, and

      • (iii) data that can be used to identify its make, model and serial number or, if the serial number is not known or cannot be obtained, unique alphanumeric identifier.

  • Marginal note:Continuous operation

    (4) The non-resettable hour meter, the other non-resettable device or the SCADA system must operate continuously, other than during periods when it is undergoing normal servicing or timely repairs.
