Noise Mitigation Measures and Screening Criteria
|BACK to Meetings Notes||
February 23, 2000
TO: LFA/Bill Willkie, Project Manager
FROM: 150 Study Group/Lt Col Tom Marks, Chair
SUBJECT: Noise Mitigation Measures and Screening Criteria
The attached noise mitigation measures are a consolidated listing of those adopted by the 150 Study Group at its February 3 meeting. Most of the committees who reviewed measures proposed last month found them thorough and comprehensive. Consequently, the attached list essentially reiterates, with minor enhancements, the accounting in your January 13 presentation. Note that the list also omits any characterization of measures as "mandatory" or "voluntary", to avoid any prejudice to the analysis.
Because of the breadth of the measures to be considered, screening criteria have been expanded and refined to provide for full and fair initial evaluation. Please let me know if any of the changes you see needs further clarification.
A couple of collateral points deserve special emphasis. As noted in the Study Groups previous memos on noise abatement measures and strategies, documentation of evolving prospects remains a critical study task. Effective implementation demands that the Group accumulate all available information on emerging technology and policy that may affect future options and directions. We therefore reiterate that measures that show promise, but may not yet be mature, must be fully documented for continued monitoring and reconsideration as circumstances warrant. We surmise that a couple of the remedial measures listed may ultimately fall into this category.
Finally, its worth emphasizing that any on-site mitigation project must be systematically planned and executed. This would include measuring the noise reduction potential of existing facilities; designing and specifying mitigation standards; re-examining facilities to verify and adjust required remediation; certifying attainment of standards; and qualified management and oversight.
Both measures and criteria are listed in abbreviated, bulletized form. Should any require elaboration beyond that provided at the Study Group meeting, please contact me without hesitation. We look forward to your consultation in moving this process forward.
