Phase 1 of the Boston Overflight Noise Study (known in Phase 2 as the Boston Logan Airport Noise Study) was a collaborative process between the Logan Airport Community Advisory Committee (CAC), the Boston Technical Advisory Committee (BOS/TAC), the Federal Aviation Administration (FAA), and the Massachusetts Port Authority (Massport), with support from the Project Consultant (PC) and the Independent Consultant (IC).

Phase 1 identified measures designed to minimize noise impacts from aircraft overflights and potentially improve the noise environs around Boston Logan International Airport. These measures were determined to be feasible based on operational, safety, and technical criteria. Two types of measures were identified:

• Measures that could be implemented without causing adverse environmental impacts. These measures may be implemented during the early stages of Phase 2.
• Measures that were determined to be safe and operationally and technically feasible, but had the potential to cause adverse environmental impacts if implemented. During Phase 2, these measures will be subjected to more detailed technical analyses to determine the significance of any environmental impacts, which will then be the subject of an environmental document to be prepared by FAA.
