4. Permit: Every person intending to build a building referred to in section 2 or develop a site referred to in that section must, before starting the work required for that purpose, obtain a permit from the local municipality having jurisdiction in the territory in which the construction or development is to take place.
A permit is also required prior to(a) the construction of an additional bedroom in an isolated dwelling or a change in its use;
(b) an increase in the operating or utilization capacity of a building or site other than an isolated dwelling referred to in section 2 or a change in its use;
(c) the construction, renovation, modification, reconstruction, moving or enlargement of a discharge, collection or disposal installation for domestic waste water, grey water or toilet effluents serving a building or site referred to in section 2;
(d) the construction of a privy serving a building or site referred to in section 2; and
(e) the installation of a compost toilet serving a building or site referred to in section 2.
Such a permit is not required for the reconstruction of a building referred to in section 2 or the redevelopment of a site referred to in that section after a fire or other disaster, to the extent set forth in the fifth paragraph of section 3.
When processing a permit application for the construction of an additional bedroom in an isolated dwelling, a change in use of a building or site or an increase in the operating or utilization capacity of another building or site referred to in section 2 that serves to increase the total daily flow of domestic waste water beyond the capacity of the system for the discharge, collection or disposal of domestic waste water, grey water or toilet effluents, the municipality is to re-evaluate the standards applicable to the system under this Regulation or, as applicable, inform the applicant that the applicant’s project is subject to section 22 of the Act.
The municipality must issue a permit under this section if the project provides for the building or site referred to in section 2 to be equipped with a system for the discharge, collection or disposal of domestic waste water, grey water or toilet effluents that conforms to this Regulation.
The municipality must also issue a permit under this section if the work does not serve to increase the total daily flow of domestic waste water beyond the capacity of the system for the discharge, collection or disposal of domestic waste water, grey water or toilet effluents.
The permit must also be issued to the extent the applicant demonstrates that any parts of the system not covered by the reconstruction, renovation, modification or moving comply with the following conditions:(a) they are designed to receive domestic waste water, grey water or toilet effluents from the building or site based on the number of bedrooms or the maximum operating or utilization capacity;
(b) they show no sign of alteration likely to compromise the system’s expected performance or, in the case of tanks and watertight systems, their watertightness; and
(c) they do not constitute a nuisance, a source of contamination of well water or spring water used for drinking water supply or a source of contamination of surface water.
This section does not apply to a municipality that has passed a by-law providing for the issue of a municipal building or enlargement permit for a building or site referred to in section 2 or for a discharge, collection or disposal installation for domestic waste water, grey water or toilet effluents under general or special legislation granting it regulatory authority for that purpose. In that case, the municipality must issue the municipal building or enlargement permit in accordance with section 118.3.5 of the Act.
In unorganized territories, the permits under this section are issued by the regional county municipality.
