Mandatory GHG Reporting Challenges
• Determining Facility Boundaries
• Contractor Sources and/or Data
• Mandatory Measurements for Input Data
• Required Quality Assurance for Measurements
• Adapting to Rule Changes
and EPA Guidance
Delivering sustainable solutions in a more competitive world
• Applicable to Subparts C, P, Y, etc.
• Compensate Gas Flow from Actual to Standard Conditions per §98.3(i)
• Local vs. Remote Location • Pressure and Temperature Transmitters
• Existing Corrections may not be Local
• Identify Remote Locations
• Perform Local Measurements
• Develop Statistical Correlations

PSD Implications of GHG MRR• PSD Major Source Determination (i.e. PTE >100k tpy CO2e)
• Convert actual emissions to potential Emissions
• Can federally enforceable conditions or synthetic limitations
be applied to stay minor?
• Tailoring Rule guidance on determining PTE
• Input Data for Historical GHG Baseline• Company records versus measured data
• Address changes in measurement accuracy
