Construction and Operation Standards
6. (1) The following are prescribed as standards for any tank used in a sewage system for collecting, treating, holding or storing sewage: 1. The tank shall conform to the requirements of Standard CAN3- B66, except as otherwise provided in this Regulation. 2. The tank, unless it is a septic tank in a Class 4 sewage system or a sewage holding tank in a Class 5 sewage system, need not conform to the requirements of Standard CAN3-B66 except those respecting material standards, access, workmanship and construction methods and practices. 3. Access openings shall be located to facilitate the pumping of all compartments and the servicing of the inlet and outlet of each compartment not accessible by the removal of the tank top or part thereof. 4. A prefabricated septic tank in a Class 4 sewage system or a prefabricated sewage holding tank in a Class 5 sewage system installed in Ontario shall bear the manufacturer’s mark indicating that the tank complies with the requirements of this Regulation and shall bear the standards mark of, i. the Canadian Standards Association, ii. the Underwriters’ Laboratories of Canada, or iii. an organization accredited by the Standards Council of Canada for certifying products of a type that include such tanks, indicating that it complies with this Regulation. (2) Subsection (1) does not apply to a tank that is used as part of a Class 7 sewage system and mounted on a vehicle or that is an integral part of a prefabricated Class 1 sewage system. (3) No person shall cover a tank regulated by subsection (1) by earth or other fill material having a depth greater than the maximum depth of burial that the tank is designed to withstand. (4) Where a report in respect of a prefabricated septic or sewage holding tank prepared in accordance with subsection (7), based on inspections performed not more than twelve months before the tank was constructed, is filed with and accepted by an employee of the Ministry designated by the Minister for the purpose, the tank shall be deemed to comply with the standard in paragraph 4 of subsection (1). (5) The records of the concrete cylinder tests prescribed in Standard CAN3-B66 for the manufacture of prefabricated concrete tanks shall be preserved for inspection by the certifying agency or by the engineer preparing the report referred to in subsection (4). (6) In this section, “engineer” means a person who is a member of the Association of Professional Engineers of the Province of Ontario who is qualified to make the tests and give the opinion required by subsection (7), and if the tanks with respect to which the report is prepared are not manufactured in Ontario, includes a professional engineer who meets similar qualifications in the province or state in which the tanks are manufactured. (7) The report referred to in subsection (4) shall be prepared, filed and accepted in accordance with the following rules: 1. The report shall, i. be prepared by an engineer, ii. state the qualifications of the engineer who prepared the report, iii. if the engineer who prepared the report is not a member of the Association of Professional Engineers of the Province of Ontario, include a copy of a certificate or letter of the governing body of the professional engineers in the jurisdiction in which the tanks with respect to which the report is prepared are manufactured indicating that the person meets qualifications equivalent to those required for membership in the Association of Professional Engineers of the Province of Ontario, iv. state that the engineer who prepared the report has no direct or indirect financial connection as an owner, employee or otherwise with the manufacturer of the tanks with respect to which the report is prepared other than for the preparation of the reports and except for such other services as an engineer provides that are mentioned in the report, v. state that the engineer who prepared the report has inspected the plant in which the tanks being reported on are manufactured and the concrete cylinder strength test records mentioned in subsection (5) and has selected at random, inspected and tested a representative tank of each model to which the report relates, vi. state the tests that have been performed on each tank, which tests shall include the strength and leakage tests prescribed by Canadian Standards Association Standard CAN3-B66, vii. state that the engineer who prepared the report has performed such tests as are necessary to form an opinion and that he or she is of the opinion that each tank tested met the standards prescribed by this Regulation, that the plant, equipment and system of production are capable of producing such tanks and that he or she has no reason to believe that any tanks of the models and sizes the report relates to that are being made in the plant do not meet the standards prescribed by this Regulation, with such exceptions as are specified in the report, viii. specify the tanks, models and sizes of each model to which the report relates, ix. include scaled or dimensioned drawings showing the plan and elevations of each model of tank to which the report relates, and x. include a general description of the plant, its location and the equipment used for making the tanks. 2. The engineer preparing a report shall make the inspections and tests necessary for the report as often as he or she considers necessary. 3. Subject to subparagraph vii of paragraph 1, the engineer preparing a report need not carry out strength and leakage tests on each size of a model of tank to which the report relates. 4. Where a report is not the first report submitted under this section by the engineer who prepared it with respect to the models and sizes of tanks of the manufacturer that the report relates to, it may, instead of the requirements of paragraph 1, state when the tests and inspections on which it is based were performed, those tests not conducted and judged not necessary in order to report continued compliance with this Regulation and such other matters referred to in paragraph 1 as have changed from the previous report.
