16  Sites affected by attrition

 (1) If a site in a population in the project is affected by attrition during the crediting period for the project, the site must be excluded from the population on and after the day the site becomes affected by attrition, until the end of the crediting period for the project.

Note: For the purposes of Part 4, sites may be excluded from the beginning of a measurement period: see section 35.

 (2) A site is affected by attrition if:

 (a) the consumption of natural gas, or electricity from an electricity grid, (or both) by a small energy user at the site has been measured as part of the project through one or more metered accounts relating to that user, and one or more of those metered accounts is terminated, resulting in data about energy consumption at the site ceasing to be available for at least one energy source chosen for the site under section 20; or

 (b) for a reason beyond the control of the project proponent for the project:

 (i) the occupant of the site makes a written request to the project proponent that data about the occupant’s energy consumption not be used for the purpose of calculating the carbon dioxide equivalent net abatement amount for the project; or

 (ii) the project proponent otherwise ceases to have a legal right to access and use data about energy consumption from an energy source chosen for the site under section 20; or

 (c) for a site in a population that consists of sites of a particular type—the site ceases to be a type of site in the population.

Note 1: Reasons for terminating a metered account include switching to a different energy retailer, disconnecting the service, or relocating to a different site.

Note 2: If a site ceases to be one type of site in the population, but is a site of a different type in the population, the site is not affected by attrition.
