Summary
Omaha exempts emergency generator noise from its dBA limits during power outages entirely, but caps routine maintenance testing to 7:00 a.m.-9:00 p.m. under the zoning performance standards.
Noises emanating from emergency generator engines during routine maintenance events or periods of partial or total loss of electrical power. Emergency generator operations during routine maintenance events are limited to between the hours of 7:00 a.m. and 9:00 p.m. Emergency generator operations during periods of partial or total loss of electrical power are not subject to time of day restrictions.
Full Breakdown
Omaha's noise performance standards (Sec. 55-804) set maximum sound levels by zoning district, from 55 dBA overnight in residential zones up to 85 dBA in heavy industrial zones. Emergency generator engines get a specific carve-out: noise from routine maintenance testing is only exempt from these limits between 7:00 a.m. and 9:00 p.m., while noise from a generator actually running during a partial or total loss of electrical power is exempt around the clock, with no time-of-day restriction at all.
Violations & Fines
No specific penalty is listed for this section, so it falls under the Code's general penalty (§ 1-10): up to a $500.00 fine, up to six months imprisonment, or both, with each day of continuing violation a separate offense.
