1.1 The process for NPI reporting Step 1: Identify all the internal combustion engines employed within the site boundary (This in cludes all the vehicles used for transport within the site, this does NOT include the personal vehicles owned by employees and the vehicles

in the car park) Step 2: Determine the total fuel usage/ kilometres travelled/ number of operational hours (activity data) Step 3: Determine whether any of the thresholds have been exceeded Step 4: Estimate the emissions and transfers for your facility (Generally use emission factors to determine emissions) Step 5: Report emissions to the NPI (Following the addition of emissions from other sources to your report) Refer to Section 4 Threshold calculations Refer to Section 2 Processes and emissions Refer to Section 5 Emission estimation techniques Refer to Section 3 Emission sources Refer to
