Aircraft noise is regulated by the FAA, not Baltimore County. Maryland COMAR explicitly does not apply to aircraft in flight, and local governments cannot set flight-noise limits. Complaints about BWI or overflights go through the airport and FAA noise programs.
Neither Baltimore County's noise code nor Maryland COMAR sets aircraft flight-noise limits, because aviation noise is federally preempted under FAA authority. COMAR 26.02.03 environmental noise standards do not cover aircraft in flight. Residents near Baltimore/Washington International (BWI) Airport can direct overflight-noise concerns to the airport's noise office and the FAA, which manage flight paths and noise-abatement programs. Ground-based airport equipment may still fall under COMAR limits, but in-flight aircraft noise is outside county and state jurisdiction.
No county penalty applies; aircraft noise is handled through FAA and airport noise-abatement programs, not local citations.
