8.46. A contractor or owner-builder may not carry out alteration work to an underground tank that may be abandoned on site, unless the contractor or owner-builder has obtained the certificate of a person recognized under section 8.13, stating that

(1)  removing the tank would jeopardize the integrity of the building’s structure or of a part that is essential for the intended use of the building; or

(2)  the machinery required for the removal of the tank cannot be taken onto the site.

The contractor or owner-builder must then

(1)  remove all sludge from the tank so as to prevent any explosion and dispose of it in a tank or other closed container compatible with petroleum products;

(2)  remove the piping from the ground;

(3)  purge the tank of all vapours until the concentration is less than 10% of the lower explosive limit; and

(4)  fill the tank with inert material such as sand, gravel or concrete and plug the openings.
