15  Selecting sites for a control group or treatment group
 (1) Before the start of the first measurement period for a population in the project, the project proponent for the project must select sites in the population for the control group and the treatment group using a random selection method (the initial selection).
Note 1: The control group and treatment group may include a different number of sites.
Note 2: Using a random selection method, sites may be selected for the treatment group, and all remaining sites are selected by default for the control group, or vice versa. Alternatively, sites may be selected for the treatment group, other sites may be selected for the control group, and all remaining sites are not selected for either group.
 (2) If the project proponent adds sites (the subsequent selection) to the control or treatment group after the initial selection for the population;
 (a) each of those sites in the subsequent selection must be:
 (i) added at the start of a measurement period for the population; and
 (ii) selected using a random selection method; and
 (b) the ratio of the number of sites selected in the subsequent selection for the control group relative to the number of sites selected in the subsequent selection for the treatment group must be the same as the ratio for the initial selection.
 (3) An accredited statistician must certify that the selecting of sites was done in accordance with this section.
 (4) Subject to section 16, if a site is selected for the control group or treatment group, the site must be retained in that group until the end of the crediting period for of the project.
