Summary
Waterbury requires an effective muffler on any stationary internal combustion engine, including a portable or standby generator, so its exhaust noise doesn't discharge into the open air unmuffled. Code of Ordinances § 97.05(C)(6) bans loud or explosive exhaust sound from stationary engines alongside motor vehicles.
(6) Exhaust discharge. The discharge into the open air of the exhaust of any steam engine, stationary internal combustion engine, motor vehicle engine, motorcycle engine, motorboat engine or any other vehicle engine except through a muffler or other device which will effectively prevent loud or explosive noises therefrom.

Full Breakdown
' A 'stationary internal combustion engine' covers a fixed or portable backup generator, a compressor engine or similar gas or diesel-powered equipment kept in one place, not just cars and boats; the rule requires the exhaust to run through a muffler or comparable device that actually stops the loud or explosive exhaust noise, not merely a token pipe. 05(B) allows a Police Department officer to cite an unmuffled generator on sight, without a calibrated sound-level reading. 04(B). 04(E)(7) only covers noise from equipment operated during daytime hours, capped at the chapter's maximum levels at night, and does not exempt an unmuffled exhaust from a standby or job-site generator at any hour.
Violations & Fines
An unmuffled generator or engine violation is fined under the fee schedule attached to the city budget per § 41.11, and § 97.99 treats each additional day after a correction order as a separate offense. The Director of Health or Superintendent of Police can inspect and test the equipment under § 97.07, with a cease-and-desist order and hearing available under § 97.09 for repeat problems.
