Summary
Springfield exempts emergency electric generators, along with safety signals and pressure-relief valves, from the Land Development Code's noise standard, so generator noise itself isn't capped or restricted by the zoning code.

Full Breakdown
LDC § 36-485(3)(c) lists the noises exempt from Springfield's zoning noise standard entirely. Emergency electric generators are grouped with safety signals, warning devices, and emergency pressure relief valves as exempt uses, so a generator running during a power outage or for backup testing isn't measured against the code's general 'unreasonably and knowingly disturb' rule that otherwise governs industrial and commercial noise sources. Construction noise between 7:00 a.m. and 11:00 p.m. is separately exempted. The exemption reads as an unconditional carve-out, it applies citywide and isn't limited to any particular zoning district or time of day.
Violations & Fines
Not applicable: generator noise covered by this exemption isn't a code violation regardless of volume, since § 36-485 excludes it from the sound level standards.
