  • (b) has been identified under subsection (5) with another boiler or heater whose NO_x emission intensity is determined for that given hour by means of a CEMS test as a rolling hourly average.

• Marginal note:Greater of stack test and CEMS test

  (2) The NO_x emission intensity of a boiler or heater referred to in paragraph (1)(a) for each hour is the greater of

  • (a) the result of a stack test that is applicable to that hour, and

  • (b) the rolling hourly average for that hour determined by means of a CEMS test conducted on the other boiler or heater referred to in paragraph (1)(b).

• Marginal note:Identification

  • (a) they have the same manufacturer;

  • (b) they have the same rated capacity;

  • (c) they are designed to have the same NO_x emission intensity;

  • (d) they have the same equipment to preheat air, if any;

  • (e) they combust fuel from a common source;

  • (f) they are juxtaposed; and

  • (g) they are

    • (i) both class 80,

    • (ii) January 1, 2026;

  • (b) for class 70 boilers or heaters, the earlier of

    • (i) the recommissioning date of the boiler or heater referred to in paragraph (1)(a), if it underwent a major modification, and

    • (ii) January 1, 2036;

  • (c) for transitional or modern boilers or heaters, the commissioning date of the boiler or heater referred to in paragraph (1)(a); and

  • (d) for redesigned boilers or heaters referred to in section 10, the recommissioning date of the boiler or heater referred to in paragraph (1)(a).

• Marginal note:Identification by recording

  (5) The identification is made on the recording of the following information:

  • (a) the name of the manufacturer — along with the serial number, make and model — of the boiler or heater referred to in paragraph (1)(a);

  • (b) the name of the manufacturer — along with the serial number, make and model — of the other boiler or heater referred to in paragraph (1)(b);

  • (c) documentation that establishes that those boilers or heaters meet the conditions set out in paragraphs (3)(b) to (g);

  • (d) an indication that the boiler or heater referred to in paragraph (a) is identified with the boiler or heater referred to in paragraph (b); and

  • (e) the date of the recording.

• Marginal note:At most four identifications

  (6) At most four boilers or heaters may be identified under subsection (5) with a given other boiler or heater referred to in paragraph (1)(b).
