Phase 2 of the Boston Logan Airport Noise Study continues the work begun in Phase 1 (known as the Boston Overflight Noise Study). During Phase 1, 53 airspace and operational measures were identified to potentially improve the noise environment around Boston Logan International Airport.

• Following an initial screening process, 18 of those measures were eliminated.
• The remaining 37 measures were examined during a second screening process.
  • Of these measures, 23 were identified in Phase 1 as Early Implementation Alternatives (eventually combined into 13 alternatives), not necessitating an Environmental Assessment (EA) or Environmental Impact Statement (EIS).
  • The remaining 14 measures, combined into 12 measures, will be further evaluated in Phase 2 to determine potential noise impacts to surrounding communities.

Any measure found to provide more equitable distribution of noise by the communities and acceptable to the Federal Aviation Administration (FAA) for implementation during Phase 1, but also might be found to generate significant noise effects (with the potential to be mitigated) or substantial public controversy, was carried over for inclusion in the evaluation process of Phase 2.
