under Part 4.
Note:  If the boundary for an implementation includes emissions-producing equipment that provides steam, heat, cooling or compressed air partly to other equipment in the boundary and partly to external equipment, the project proponent will be able to deduct the fuel of electricity attributable to the output provided to the external equipment from the abatement calculations.

  Attribution of fuel or electricity

 (4) The fuel or electricity consumed by partly unaffected emissions-producing equipment is attributed to the internal and external outputs:
 (a) in the same proportion as the energy content of those outputs; and
Example:  If a boiler supplies two-thirds of its steam output (by energy content) to other equipment in the boundary for the implementation and one-third to equipment outside of the boundary, then the energy content of one-third of the steam output can be excluded from the boundary.
 (b) if the partly unaffected emissions-producing equipment consumes lower grade energy originally created by the equipment and returned to it—the net of the energy content of any lower grade energy being returned to the partly unaffected emissions-producing equipment.
Example:  If a boiler produces and supplies steam to the rest of the equipment in the boundary and lower temperature steam is returned to the boiler for re-use, then the fuel consumption by the equipment should be attributed based on the net difference between the original and returned steam.
