The purpose of this report is to examine the feasibility and reasonableness factors in the Federal Highway Administration (FHWA) noise regulation in 23 Code of Federal Regulations (CFR) Part 772 as implemented in the individual state highway agency (SHA) noise policies individually and in combination with each other to identify optimized combinations of values. The report specifically addresses the requirements of Tasks 3.1 through 3.5 of the FHWA Task Order No. DTFH61-D-00028-T12-002, 23 CFR 772 Streamlining, Analysis, and Outreach.
The contents of this report are meant for research purposes only and shall not be considered FHWA policy, guidance and/or requirements.
This report is comprised of the following four chapters:
This report was prepared for and reviewed by FHWA and the project's Technical Working Group (TWG), first as a draft report and then as an interim report. It addresses comments received from FHWA and the TWG during the review process. The intended audience includes analysts and policy-makers within FHWA and SHAs who specialize in highway traffic noise and National Environmental Policy Act (NEPA) implementation policies, processes and procedures.
This is the first printing of this report.
This report is the first of two Final Task 3 Deliverable Documents.

15. Supplementary Notes
This report examines the feasibility and reasonableness factors in the FHWA noise regulation (23 CFR 772) as implemented in the individual state highway agency noise policies. The studied factors include:
The analysis examines how changes in the permissible ranges for each factor - while the others factors remain static - affect noise abatement decisions. Also examined is how changes to multiple factors in combination affect decisions. The goal was to identify combinations of factors that are likely to result in inclusion or exclusion of noise abatement. The range in potential decisions based on the combinations permitted under the regulation is examined to provide an aid for future policy guidance and planning. A sensitivity analysis on the factors identifies outcomes of possible combinations of factors. Actual highway projects are also used to identify the effects on the likelihood of abatement. Reported separately is the development of tools to evaluate the effects of policy changes on abatement feasibility and reasonableness.
