Portable monitoring instruments 5 (1) A portable monitoring instrument must meet all of the following requirements: (a) it must meet the specifications set out in sections 6.0 to 6.6 of EPA Method 21, except that the nominal sample flow rate must be 0.2 to 1.2 litres per minute, rather than the nominal sample flow rate set out in section 6.4 of that Method; (b) it must be maintained in accordance with the manufacturer’s specifications for that instrument, if any; (c) it must, before it is first used on any day, be calibrated in accordance with sections 7.0 to 8.2, 10.0 and 10.1 of EPA Method 21, with the following modifications, namely, (i) the response factor referred to in section 8.1.1 of EPA Method 21 must be determined using methane (for a flame ionization detector) or isobutylene (for a photoionization detector) as the reference compound and, if the response factor of the fluid with which an equipment component comes into contact is determined to be less than one, it must not be applied to the reading resulting from an inspection of that component, (ii) the calibration precision test referred to in section 8.1.2 of EPA Method 21 must be performed before the instrument is first used on any day, (iii) the response time test referred to in section 8.1.3 of EPA Method 21 must be performed before the instrument is first used on any day, (iv) the instrument response time set out in section 8.1.3.2 of EPA Method 21 must be less than or equal to five seconds, and (v) the calibration described in section 10.1 of EPA Method 21 must be completed by assigning the instrument’s internal detector count to the known concentration of the calibration gas rather than by adjusting the instrument meter readout to correspond to the known concentration of the calibration gas; (d) for the purpose of measuring the concentration of VOCs, it must be operated in accordance with sections 8.3 to 8.3.1.8 of EPA Method 21; and (e) it must undergo a calibration drift assessment at the end of each day on which it is used, in accordance with the requirements set out in section 60.485a(b)(2) of Title 40, subpart VVa of the Code of Federal Regulations of the United States. Optical gas-imaging instruments (2) An optical gas-imaging instrument must meet the following requirements: (a) it must meet the specifications set out in section 60.18(h)(7)(i)(1) of Title 40, subpart A of the Code of Federal Regulations of the United States; (b) it must be operated and maintained in accordance with the manufacturer’s specifications for that instrument, if any; (c) it must, before it is first used on any day, be checked in accordance with sections 60.18(h)(7)(i)(2)(i) to (v) of Title 40, subpart A of the Code of Federal Regulations of the United States; and (d) when used to inspect an equipment component of which the instrument has no direct view, including when the component is covered with insulation, the instrument must be operated so that images can be seen at locations where VOCs that are leaking from the component may be present, such as openings in the insulation and locations where the insulation ends. Detection sensitivity level (3) For the purpose of paragraphs (2)(a) and (c), the required detection sensitivity level is 60 grams per hour.
