Summary

Part 98 requires covered facilities and suppliers to monitor and report greenhouse gas data each year. It is a reporting program, not a permitting program: it does not by itself set emission limits. Subpart A holds the General Provisions; source-category subparts set what is reported and how it is calculated.

Applicability

Applicability is set by source category and by the criteria in Subpart A and each source-category subpart. Read the applicability sections directly; AirPermitHub does not restate the reporting thresholds.

Requirements

Monitoring
