Okla. Stat. tit. 2, § 2-20-57

A. Except as authorized by this subsection, no liquid animal

waste shall be land applied within five hundred (500) feet of the

nearest corner of an occupied residence not owned or leased by the

owner of the animal feeding operation.

B. Except as provided by Section 20-58 of this title, no

concentrated animal feeding operation shall be established after

September 1, 1997, which is within one (1) mile of ten or more

residences that are occupied residences at the time of the

establishment of the concentrated animal feeding operation.

C. The proscription contained in subsections A and B of this

section shall not apply if the applicable property owner executes a

written waiver with the owner or operator of the animal feeding

operation, under the terms and conditions that the parties

negotiate. The written waiver becomes effective upon recording of

the waiver in the offices of the recorder of deeds in the county

where the property is located. The filed waiver shall preclude

enforcement of the setback requirements contained in subsections A

and B of this section. A change in ownership of the applicable

property or change in the ownership of the property on which the

hundred (300) feet of an existing public or private drinking water

well.

1. Within three (3) miles of a state park or resort;

2. On land within three (3) miles of the incorporated limits of

any municipality, unless the municipality's governing body executes

a written waiver of the setback for the particular animal feeding

operation. A change in ownership of the property on which the

animal feeding operation is located shall not affect the validity of

the waiver;

3. Within three (3) miles of the high water mark of a surface

public water supply if the concentrated animal feeding operation is

located within the drainage basin for the public water supply.

F. All distances between occupied residences and animal feeding

operations shall be measured from the closest corner of the walls of

facility, as determined by the Oklahoma Department of Agriculture,

Food, and Forestry. The property boundary line of the real property

is not used unless it coincides with the closest point of the waste
