## Abstract

This final policy establishes a distinction between remedial and preventive noise mitigation measures proposed by airport operators and submitted for approval by the Federal Aviation Administration (FAA) under applicable noise compatibility planning regulations. Implementation of this policy also results in certain new limitations on the use of Airport Improvement Program (AIP) funds for remedial noise mitigation projects. The proposed policy was published in the Federal Register on March 20, 1995 (60 FR 14701), and public comments were received and considered. On May 28, 1997, the revised policy as proposed for issuance was published in the Federal Register. However, prior to the issuance of the policy the FAA requested supplemental comment on the impact of its limitations on PFC eligibility. The FAA considered the comments on PFC eligibility thus received and has revised the final policy. All other issues were considered to have been adequately covered during the original comment period. Accordingly, as of October 1, 1998, the FAA will approve under 14 CFR part 150 (part 150) only remedial noise mitigation measures for existing noncompatible development and only preventive noise mitigation measures in areas of potential new noncompatible development. The FAA will not approve remedial noise mitigation measures for new noncompatible development that occurs in the vicinity of airports after the effective date of this final policy. As of the same effective date, the use of AIP funds will be affected to the extent that such use depends on approval under part 150. Since this policy only affects part 150 approvals, it does not apply to projects that can be financed with AIP funds without a part 150 program. The bulk of noise projects receive AIP funding pursuant to their approval under part 150. After review and consideration of comments received, FAA has determined that this policy need not affect financing noise projects with passenger facility charge (PFC) revenue bec
