Directs the State Auditor to evaluate Port Package noise mitigation retrofits (double/triple-paned windows, insulation, HVAC) by July 1, 2029. References the State Aircraft Noise and Air Quality Mitigation Account created in SB 6240; directs the Department of Commerce to administer a mitigation grant program.
