HRS §46-17
County rules for noise, smoke, dust, vibration, and odors
Counties can make and enforce local laws about noise, smoke, dust, vibration, or odors that are public nuisances. These local laws stay valid even if state laws cover the same topics. If a local law conflicts with a state law or rule, the one that protects the public more wins, except for certain state permits and rules.

The statute, as written — Regulation of certain public nuisances
Any provision of law to the contrary notwithstanding, the council of any county may adopt and provide for the enforcement of ordinances regulating or prohibiting noise, smoke, dust, vibration, or odors which constitute a public nuisance. No such ordinance shall be held invalid on the ground that it covers any subject or matter embraced within any statute or rule of the State; provided that in any case of conflict between a statute or rule and an ordinance, the law affording the most protection to the public shall apply, with the exception that: (1) An ordinance shall not be effective to the extent that it is inconsistent with any permit for agricultural burning granted by the department of health under authority of chapter 342B, or to the extent that it prohibits, subjects to fine or injunction, or declares to be a public nuisance any agricultural burning conducted in accordance with such a permit; and (2) An ordinance shall not be effective to the extent that it is inconsistent with any noise rule adopted by the department of health under authority of chapter 342F.
