Special provisions applicable to Basse-Côte-Nord: This section applies to the municipalities of Blanc-Sablon, Bonne-Espérance, Côte-Nord-du-Golfe-du-Saint-Laurent, Gros-Mécatina and Saint-Augustin, as well as any other municipality constituted under the Act respecting the municipal reorganization of the territory of Municipalité de la Côte-Nord-du-Golfe-du-Saint-Laurent (1988, chapter 55; 1996, chapter 2).
In addition to the modes of treatment and discharge into the environment referred to in the third paragraph of section 3, the grey water and toilet effluents of an isolated dwelling may also be carried towards a waste water disposal and treatment installation referred to in the waste water depollution plan of the municipality or part of the municipality.
The waste water depollution plan must
(1) indicate the territory to which it applies;
(2) indicate existing subdivisions and dwellings;
(3) indicate the presence and location, on the territory to which it applies, of any public or private work for the catchment or treatment of drinking water and any public or private work for the collection, treatment or disposal of waste water;
(4) include a characterization study of the natural land conducted in accordance with subparagraph 4 of the first paragraph of section 4.1;
(5) delimit the sectors where it is possible to install treatment systems complying with Divisions III to X;
(6) delimit the sectors where it is possible to install waste water disposal and treatment installations grouping more than 1 residence and indicate the installations intended for each group;
(7) for sectors where subparagraph 5 or 6 cannot be applied, indicate for each residence the systems for the disposal, collection and treatment of waste water and the layout related to such equipment so that the discharged water is not harmful to the health and safety of persons and the environment; and
(8) indicate the measures for installing, using and maintaining the systems provided for in the depollution plan.
The waste water depollution plan is prepared and signed by an engineer who is a member of the Ordre des ingénieurs du Québec.
The waste water depollution plan must be accompanied by a resolution of the municipality whereby the municipality, under section 25.1 of the Municipal Powers Act (chapter C-47.1), takes charge of the maintenance of the treatment systems provided for in subparagraphs 5 and 7 of the third paragraph.
The waste water depollution plan is submitted to the Minister to be approved. It is valid for 5 years from its approval. In order to renew it, a municipality must apply to the Minister 180 days before the end of the 5-year period. If information or documents have already been provided to the Minister upon a previous application, it is not necessary to provide them again if the municipality certifies that they are still accurate.
Section 32 of the Act does not apply to the waste water disposal, collection or treatment systems provided for in subparagraphs 6 and 7 of the third paragraph if they are part of a depollution plan approved by the Minister.

94. Notwithstanding section 11, prefabricated septic tanks that comply with BNQ 3680-505, BNQ 3680-510 and NQ 3680-901 standards may be installed until 31 December 2002.
O.C. 1217-2000, s. 2;
O.C. 903-2002, s. 3.
95. Provisional: Until 31 December 2005, despite the requirement in sections 11.1, 16.2, 87.8 and 87.14 to comply with NQ Standard 3680-910, a waste water
disposal system using standard technology for a hydraulic capacity equal to or greater than the total daily flow from an isolated dwelling or other building served by the disposal system may be installed, subject to the conditions set out in this section.
For the purposes of this section, a disposal system's technology is standard if the technology was the subject of an evaluation report made to the Minister of Sustainable Development, Environment and Parks by an engineer who is a member of the Ordre des ingénieurs du Québec, and the system's effluent complies with the effluent discharge standards according to the type of disposal system concerned and related system supply conditions.
The evaluation report must contain
(1) a description of the technology;
(2) the technical specifications and design criteria of each of its components;
(3) the specifications concerning the stages of preliminary treatment;
(4) the expected performance;
(5) the limits of the technology;
(6) a detailed analysis of the justifications (results of monitoring, former use or documentation, as the case may be);
(7) the manufacturer's recommendations on the operation, inspection and maintenance of the technology; and
(8) the engineer's signature.
The engineer's report must be based on tests carried out over 1 year, supervised by an independent body, on at least 1 installation in conditions equivalent to those in which the technology is to be used, and consisting of 16 affluent and effluent samples and measurement of the flow over that year; the samples must be taken monthly, 6 of which must be taken over 2 periods of 3 consecutive days, one in January, February or March, the other in July, August or September. The samples must be analyzed in accordance with section 87.32 and the test results recorded in a report prepared by the independent body.
If a disposal system's technology is standard, the Minister is to publish, on a medium based on information technology and, where the Minister considers it advisable, by any other means, a technical evaluation record specifying the features of the technology, the extent of its application, its design criteria, the maintenance rules for the disposal system, the level of development and the performance obtained. Publication of the record exempts the system installation from the provisions of section 32 of the Environment Quality Act (chapter Q-2).
The standards in this Regulation that apply to watertightness, siting, installation, use, maintenance and sampling in respect of a disposal system referred to in a section listed in the first paragraph as well the requirement in section 3.4 apply, with the necessary modifications, to a standard disposal system.
