2. Schedule 1 to the Regulation is revoked and the following substituted:

Schedule 1
FACILITY CLASSIFICATION POINT SYSTEMS

1. A wastewater collection facility is classified in accordance with Table 1 of this Schedule, based on the number of points applicable to the facility under the point system described in Schedule 1.1.

2. A wastewater treatment facility is classified in accordance with Table 1 of this Schedule, based on the number of points applicable to the facility under the point system described in Schedule 1.2.

3. (1) For the purpose of section 2, the number of points applicable to a package wastewater treatment facility under the point system described in Schedule 1.2 may be reduced by the Director if he or she is satisfied that the operational needs of the package wastewater treatment facility are less than the operational needs of other wastewater treatment facilities.

(2) In subsection (1),

“package wastewater treatment facility” means a wastewater treatment facility where the treatment processes of the facility meet the following criteria:

1. The facility has been manufactured as a complete unit.

2. The facility has been preassembled and delivered in not more than four modules to the site where it is used.

3. The facility has a design flow of 1,300 cubic metres per day or less.
