FAA releases new Program Guidance Letter 12-09 for noise insulation programs

The FAA recently released Program Guidance Letter (PGL) 12-09, which imposes a new two-step eligibility requirement for Airport Improvement Program-funded noise insulation projects, including requiring that structures ust have a noise level equal to or greater than 45 dB day-night average sound level (DNL) prior to insulation. The new requirements represents a major change for many ongoing programs and practices.
