Drafting an EPA Subpart W methane report from leak survey data
The Methane Filing Engine drafts an EPA Subpart W report from infrared leak surveys and shows the derivation behind every number.
The problem
Oil and gas operators must turn infrared leak surveys into an annual EPA Subpart W methane report. Most do it by hand in spreadsheets.
What it does
- Reads the survey export the operator already has.
- Drafts the Subpart W report.
- Shows the full derivation behind every number: emission factor, leak duration, unit conversions and the regulation behind each step.
- Uses AI only to suggest column mappings when fixed rules cannot.
- Holds everything as a draft until a qualified reviewer signs off.
The decision behind it
One of Dawood's six rules: AI at the door, never at the calculator
AI reads the messy files coming in, plain code does the math and a person signs off. The AI never touches a calculated number.
