The second phase of the Part 150 process is to draft the _______.

• A. NCP
• B. DNL Report
• C. Noise Abatement Plan
• D. Environmental Impact Statement

Answer: (A)

Phase II centers on drafting the Noise Compatibility Program. This document takes the findings from Phase I—such as the noise exposure maps and DNL analyses—and translates them into a concrete set of proposed mitigation measures, an implementation plan, responsibilities, and funding. It’s the formal plan that airports and sponsors implement to reduce noise impacts on surrounding communities. The Environmental Impact Statement is a broader NEPA document that might be required in some cases but is not the second phase of Part 150, and the DNL report itself is part of Phase I data rather than the plan developed in Phase II.
