19Identifying the boundary for each implementation

19  Identifying the boundary for each implementation

 (1) A project proponent must identify a boundary for each implementation included in the project.

 (2) The boundary for each implementation must include:

 (a) at least one item of emissions-producing equipment; and

 (b) each item of equipment that is the subject of the implementation activities that constitute the implementation that has not been identified as interactive equipment; and

 (c) for an implementation that includes the implementation activity referred to in paragraph 12(2)(f)—the existing emissions-producing equipment referred to in that paragraph; and

 (d) each other item of equipment that could reasonably be expected to experience an increase in emissions that is not immaterial or minor because of the implementation.

Note: All increases in emissions that occur because of the implementation must be accounted for in the net abatement calculations unless the change in emissions is excluded under section 43. If an item of equipment experiences an increase in emissions because of the implementation that is an immaterial or minor increase, the project proponent may choose to account for that change by including the item of equipment in the boundary for the implementation or by identifying the change in emissions as an interactive effect. For example, if, as part of a large gas turbine optimisation, associated electricity-consuming equipment experiences a small increase in electricity-consumption emissions, the proponent may choose whether to include the electricity consuming equipment in the boundary for the implementation or account for the electricity-consumption emissions change as an interactive effect.

 (3) The project proponent must separately identify:

 (a) the boundary in its form before the implementation has commenced (the original boundary for the implementation); and

 (b) the boundary in its form after implementation activities have been completed (the upgraded boundary for the implementation).

 (4) The original boundary and upgraded boundary for the implementation need not be identical but can only differ to the extent necessary to accommodate changes due to the implementation activities included in the project.

Example: An upgraded boundary may differ from the original boundary as a result of the removal of equipment or the installation of additional equipment or components.

 (5) When defining the boundary for an implementation, the project proponent may specify emissions-producing equipment within the boundary for the implementation as partly unaffected, in accordance with section 20.

 (6) A project proponent must prepare a detailed description of any boundary identified under this section, in the form of a description of the items of equipment that the project proponent is treating as being within the boundary and any equipment specified as being partly unaffected. This may be supported by diagrams such as site maps or plant schematics.
