Compliance Assessment Indicators (CAI)

Questionable Fuel Volume – CAI 125

Some companies have asked how the Compliance Assessment Indicator (CAI) Questionable Fuel Volume is determined. This CAI helps identify instances when the volume of gas reported as fuel deviated by more than +/- 75% from the fuel usage volume expected for various facility subtypes. An operator who has this CAI appearing on their monthly compliance assessment report may want to confirm the accuracy of the reported fuel gas volumes.

We have developed the Questionable Fuel Volume – Facility CAI spreadsheet to determine the fuel usage volume expected for various facility subtypes. The spreadsheet uses two assumptions:

  • the typical equipment that we might expect to see at a specific facility subtype, and
  • the amount of fuel that each piece of equipment may use based on manufacturer specifications.

Based on these assumptions, we developed a formula to estimate fuel usage volume for each facility subtype. The CAI will not be triggered unless the reported fuel volume is +/- 75% of the fuel usage estimate

Operator's Handbook

Our EPAP Operator’s Handbook can help operators improve their compliance with Directive 076 requirements. The handbook includes the following:

  • our expectations regarding the level of assurance over compliance with AER measurement and reporting requirements
  • things to consider when designing controls
  • details on how to
    • evaluate the effectiveness of controls,
    • maintain the control designs to ensure that they address any risk of noncompliance,
    • interpret and use the compliance assessment reports to identify and track issues, and
    • make an annual declaration.
