Mitigation funding

(a) In general Not later than 180 days after the release of an action plan pursuant to section 3, the Administrator shall make grants for necessary noise mitigation in a designated community for— (1) residences; (2) hospitals; (3) nursing homes and adult or child day care centers; (4) schools; (5) places of worship; and (6) other impacted facilities indicated by a community assessment under section 5(f). (b) Standards Using the framework and diagnostic tool developed by the National Academy of Sciences under section 3, the Administrator shall develop standards to determine which of the structures in designated communities described in subsection (a) are eligible for mitigation funding. (c) Mitigation defined In this section, the term noise mitigation means any form of mitigation that reduces the noise burden for communities, including— (1) sound insulation of structures; (2) construction of noise barriers or acoustic shielding to mitigate ground-level noise; and (3) other mitigation as indicated by a community assessment under section 5(f) or an action plan under section 6 using the diagnostic tool developed by the National Academy of Sciences under section 3. (d) Sound insulation for communities subject to high flight frequency (1) In general Using the framework and diagnostic tool developed by the National Academy of Sciences under section 3, in carrying out an action plan described in section 6, the Administrator shall develop standards for determining which communities are subject to significant frequency of overhead flights, which shall be eligible for noise mitigation funding. (2) Noise mitigation In carrying out an action plan described in section 6, the Administrator and airport operators shall provide grants for noise mitigation for aviation-impacted communities that are subjected to a high frequency of flight operations or from the adoption of new flight procedures (as determined by the Administrator through the use of the framework and diagnostic tool developed by the National Academy of Sciences under section 3). (e) Sound insulation for residences impacted by significant night time aircraft noise In carrying out an action plan described in section 6, the Administrator and airport operators shall provide noise mitigation for a neighborhood within a 55 or higher DNL contour (or a community that has quality-assured noise measurement data that demonstrate 55 DNL impacts occurring outside the model contour of the aviation environmental design tool of the FAA) in which an airport operator or the Administrator determines, through the use of the framework and diagnostic tool developed by the National Academy of Sciences under section 3, that significant numbers of flight operations are conducted between 10:00 p.m. and 6:00 a.m.
