  • (a) three release measurements shall be made;

  • (b) each release measurement shall be made during a minimum continuous process operational period of 30 minutes;

  • (c) the asbestos fibres on each filter shall be counted by two qualified persons, one counting the odd numbered sectors and the other counting the even numbered sectors;

  • (d) each release measurement shall be determined by taking the arithmetic average of the two sets of fibre counts conducted in accordance with paragraph (c); and

  • (e) the concentration of asbestos fibres contained in gases released into the ambient air shall be the arithmetic average of the three measurements conducted in accordance with paragraphs (a) to (d).

• (5) Where Method S.2 described in the Report referred to in subsection (2) is used,

  • (a) one release measurement shall be made;

  • (b) the asbestos fibres on each filter shall be counted by two qualified persons, one counting the odd numbered sectors and the other counting the even numbered sectors; and

  • (c) the release measurement shall be determined by taking the arithmetic average of the two sets of fibre counts conducted in accordance with paragraph (b).

• (6) Where Method S.3 described in the Report referred to in subsection (3) is used,

  • (a) three release measurements shall be made;

  • (b) each release measurement shall be made during a period of continuous active drilling;

  • (c) the asbestos fibres on each filter shall be counted by two qualified persons, one counting the odd numbered sectors and the other counting the even numbered sectors;

  • (d) each release measurement shall be determined by taking the arithmetic average of the two sets of fibre counts conducted in accordance with paragraph (c); and

  • (e) the concentration of asbestos fibres contained in gases released into the ambient air shall be the arithmetic average of the three measurements conducted in accordance with paragraphs (a) to (d).

Asbestos Releases During Malfunction or Breakdown

4 Notwithstanding section 3, the concentration of asbestos fibres referred to in paragraph 3(1)(a) or (b) may, in the event of a malfunction or breakdown in the air pollution control equipment or the process equipment associated with the operations or storage referred to in that paragraph, be exceeded for not more than

• (a) 30 minutes, in the case of a single malfunction or breakdown;

• (b) a total of one hour per month, in the case of crushing or milling operations or dry rock storage; and

• (c) a total of two hours per month, in the case of drying operations.

Information and Samples

5 The Minister may request the owner or operator of a mine or mill to submit to the Minister

• (a) information and samples respecting the operation of the mine or mill;

• (b) information respecting the malfunction or breakdown of the air pollution control equipment or process equipment of the mine or mill; or

• (c) information respecting the air pollution control equipment of the mine or mill.

Mine or Mill Operations Reports

• 6 (1) Where, pursuant to paragraph 5(a), the Minister requests information respecting the operation of a mine or mill, the owner or operator of the mine or mill shall submit to the Minister the information required by the Mine or Mill Release Measurement Report set out in Schedule I.

• (2) The report referred to in subsection (1) shall be submitted in respect of samples taken from the appropriate sources at the mine or mill during the 60 days immediately preceding the date on which the information is required to be submitted to the Minister pursuant to subsection (3).

• (3) The report referred to in subsection (1) shall be submitted at intervals of

  • (a) six months, in respect of milling operations, and

  • (b) 12 months, in respect of crushing and drying operations, dry rock storage and primary dry drilling,

  such intervals to commence three months after the request is made by the Minister.

• (4) For the purposes of this section, samples shall be taken in accordance with the applicable method described in subsections 3(2) to (6).

• (5) For the purposes of this section, and at the request of the Minister, the samples shall be taken in the presence of an enforcement officer.

Submission of Samples and Related Information

• 7 (1) Where, pursuant to section 5, the Minister requests samples of gas streams released into the ambient air from a mine or mill and such related information as will enable the Minister to cause analyses to be made of the concentration of asbestos fibres in the gas streams, the owner or operator of the mine or mill shall obtain the samples at regular six month intervals in accordance with the appropriate method described in Standard Reference Methods for Source Testing: Measurement of Emissions of Asbestos from Mining and Milling Operations; Department of Fisheries and Environment Report EPS-1-AP-75-1 dated December 1976, as amended from time to time and shall forthwith submit the samples and related information to the Minister.

• (2) For the purposes of subsection (1), at the request of the Minister, the samples shall be obtained in the presence of an enforcement officer.

Malfunction or Breakdown Reports

8 Where, pursuant to paragraph 5(b), the Minister requests information respecting the malfunction or breakdown of air pollution control equipment or process equipment, the owner or operator of the mine or mill shall, not later than two months after the request is made by the Minister, submit to the Minister, for any month in which a malfunction or breakdown occurs, the information required by the Malfunction or Breakdown Report set out in Schedule II.

Air Pollution Control Equipment Reports

9 Where, pursuant to paragraph 5(c), the Minister requests information respecting air pollution control equipment at a mine or mill, the owner or operator of the mine or mill shall submit to the Minister, for each operation referred to in paragraphs 3(1)(a) to (c), the information required by the Air Pollution Control Equipment Report set out in Schedule III, not later than two months after the request is made by the Minister and at such times thereafter as any change occurs in respect of the air pollution control equipment.
