Boston Logan Environmental Data Reports and Environmental Status and Planning Reports
Environmental Status and Planning Reports (ESPRs) are prepared every 5 years and provide annual updates and long-range analysis of projected operations, passengers, and cumulative impacts.
Environmental Data Reports (EDRs) provide an annual update for the interim years on activity and environmental conditions at Logan Airport.
Older EDR/ESPR documents are located at the bottom of this page.
