  1. Waste data for 2022 and 2023 was corrected in 2023 based on an improved methodology to address omissions identified during data quality evaluation.
  2. Beginning in 2023, Delta started reporting on environmental penalties assessed instead of Notices of Violation, because notices are allegations and penalties assessed are more reflective of a final agency determination. The reported penalties include fines imposed by environmental regulatory authorities for noncompliance with air, water, waste and chemical management requirements. They do not include penalties for alleged noise violations.
