Reduction in the Release of Volatile Organic Compounds (Storage and Loading of Volatile Petroleum Liquids) Regulations — 100
Repair — tank in service 100 (1) Subject to subsections (2), (3) and 101 (1) to (4), if a defect referred to in subsection (5) is detected when a tank is in service at a facility, the operator of the facility must take one of the following measures: (a) in the case of a defect of a tank, internal floating roof or external floating roof, the operator must, within 60 days after the day on which the defect is detected, (i) remove the tank from service, or (ii) repair the defect and perform any tests or inspections necessary to confirm that the repair is successful; or (b) in the case of a defect of an internal floating roof or the tank in which it is installed, the operator must equip the tank with a temporary vapour control system within 15 days after the day on which the defect is detected and repair the defect and perform any tests or inspections necessary to confirm that the repair is successful within 180 days after that day. Tank designated under subsection 125 (1) (2) Subject to section 101 (1), if a defect of a tank designated as a deferred application tank under subsection 125 (1) can be repaired only when the tank is not in service, the repair may be delayed until the tank is removed from service. Defect to rim seal (3) In the case of a defect of a rim seal, the time limit for taking the measures referred to in subparagraph (1)(a)(ii) is extended to 90 days after the day on which the defect is detected if (a) the cumulative total surface area of all seal gaps is less than 1000 cm 2 per m of the tank’s diameter; and (b) within 30 days after the day on which the defect is detected, a person who holds a valid API 653 - Aboveground Storage Tank Inspector certificate issued by the American Petroleum Institute determines that the tank is free of any other detected defects that would prevent the repair of the rim seal while the tank is in service. Repair cannot be completed (4) If, after attempting a repair of a rim seal for the purposes of subsection (3), the operator determines that the defect of the rim seal cannot be repaired while the tank is in service, the operator must remove the tank from service within 45 days after the day on which the determination is made. Defects (5) An internal floating roof or external floating roof has a defect if (a) the tank in which it is installed does not meet the requirements of section 37 such that the efficacy of the internal floating roof or external floating roof in controlling emissions could be reduced; (b) it has a seal gap that exceeds the size requirements set out in subsections 65 (2) and (3) and 74 (2) and (3); (c) its deck has an opening that does not meet the requirements of sections 66 and 75 ; (d) in the case of an internal floating roof, the value of the LEL% in the space above it exceeds the applicable threshold set out in subsection 92 (5) or (6); (e) in the case of an external floating roof, it has inadequate drainage or an accumulation of snow, ice or debris that compromises its capacity to remain afloat on the surface of the liquid; (f) volatile petroleum liquids are observed to be present on its upper surface more than once in a 12-month period or present over an area of more than 1 m 2 ; (g) it or the tank in which it is installed has a structural defect or obstruction that could impair the movement of the internal floating roof or the external floating roof; or (h) it or the tank in which it is installed has any other defect that could reduce the efficacy of the internal floating roof or external floating roof in controlling emissions.
