Okla. Stat. tit. 2, § 2-20-19: Setback requirements

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

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 swine feeding operation.

B. Except as otherwise provided by Section 20-20 of this title,

no concentrated swine feeding operation shall be established within

one (1) mile of ten or more residences that are occupied residences

at the time of the establishment of the concentrated swine 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 swine 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

swine feeding operation is located shall not affect the validity of

the waiver.

D. No liquid swine waste shall be land applied within three

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

well.

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

concentrated swine feeding operation shall be established if

located:

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 swine 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; or

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

public water supply if the concentrated swine feeding operation is

located within the drainage basin for the public water supply.

F. All distances between occupied residences and swine feeding

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

the occupied residence to the closest point of the nearest waste

facility, as determined by the Department. The property boundary

line of the real property is not used unless it coincides with the

closest point of the waste facility or occupied residence.
