Okla. Stat. tit. 63, § 63-709.2: Noise - Exemption from liability

A. Notwithstanding any municipal ordinance or rule regulating

noise to the contrary, a governmental official may not seek a civil

or criminal penalty or injunction against a shooting range, or its

owner or operators, on the basis of noise emanating from the range,

provided the noise at the property line of the shooting range does

not exceed one hundred fifty (150) decibels.

B. No person shall bring any suit in law or equity or any other

claim for relief against a shooting range, or its owners or

operators, based upon noise emanating from the shooting range,

provided the noise at the property line of the range does not exceed

one hundred fifty (150) decibels.

C. Notwithstanding any law to the contrary, any ordinance or

rule relating to noise adopted by any local unit of government,

whether before, on, or after the effective date of this act, shall

not be deemed to be enforceable against a shooting range, provided

the noise at the property line of the range does not exceed one

hundred fifty (150) decibels. The ordinance or rule shall not serve

as the basis for any suit in law or equity, whether brought by a

governmental official or person. In no event shall the provisions

of this subsection affect the outcome of any suit brought prior to

the effective date of this act in which a final order of judgment or

relief has been entered.
