9.4.2(1) When a storage tank system has been permanently removed from service, the owner of a storage tank system shall ensure that:

  1. petroleum and allied petroleum products are removed and vapours purged from the storage tank, piping, dispensing, and transfer equipment; and
  2. the storage tank, piping, dispensing, and transfer equipment are removed.

9.4.2(2) If the site is contaminated with petroleum or allied petroleum products, the site shall be remediated to the criteria defined by:

  1. CCME PN 1299, "Canadian Environmental Quality Guidelines";
  2. CCME CWS for PHC, "Canada-wide Standards for Petroleum Hydrocarbons in Soil"; or
  3. other criteria prescribed by the authority having jurisdiction.

Section 9.5 Abandonment In-place

9.5.1 An aboveground storage tank system shall not be abandoned in-place.

9.5.2(1) In accordance with Articles 4.2.7 and 5.5.2, an underground storage tank system installed after the effective date of the Code shall not be abandoned in-place

9.5.2(2) Subject to Sentence 9.5.3(1), and Article 9.5.4, an existing underground storage tank system shall not be abandoned in-place.

9.5.3(1) An owner of an existing underground storage tank system may apply to the authority having jurisdiction for approval to abandon a storage tank system in-place by:

  1. describing fully in the application, the circumstances relating to the storage tank system location that would justify abandoning the storage tank system in-place;
  2. satisfying the authority having jurisdiction that the soil under and around the storage tank system has not been contaminated with a petroleum or allied petroleumproduct (see Appendix, note B9.5.3(1)); and
  3. providing confirmation that the owner of the property is aware and in agreement with the plan and procedures to abandon the storage tank system in-place.

9.5.4 When the authority having jurisdiction considers it impractical to remove an underground storage tank system, approval in writing may be granted to the owner to abandon the system in-place (See Appendix B, note B.9.5.4).

9.5.5(1) When the authority having jurisdiction has granted approval in writing to an owner to abandon an underground storage tank system in-place, the abandonment procedures shall ensure that:

  1. any liquid or sludge in the underground storage tank system is removed and disposed of by an acceptable method;
  2. the underground storage tank system is purged of vapours to less than 10% of the lower flammable limit and that the presence of vapours is checked with a combustible gas meter;
  3. sufficient holes are cut along the top of the underground storage tank to enable the complete filling of the storage tank with an inert material acceptable to the authority having jurisdiction(See Appendix B, Note B9.5.5(1));
  4. the underground storage tank is completely filled with an inert material acceptable to the authority having jurisdiction(See Appendix B, Note B9.5.5(1));
