Okla. Stat. tit. 19, § 19-1219: Release of area from district

A. If it becomes apparent that a certain area included within a

district cannot be economically or adequately served by the services

and facilities of the district, or no longer needs such services or

facilities, the residents of such area may petition the county

commissioners to release the area from the district. The petition

shall describe by section or fraction thereof and by township and

range the area affected and be signed by all three-fourths (3/4) of

the residents of such area and be endorsed by the board of directors

of the district.

B. After a finding that the granting of the petition is to the

best interests of the affected residents and the district, the board

of county commissioners shall issue a certificate stating that the

area involved is released and separated from the district. Full

minutes of the hearing shall be entered in the journal of the board

of county commissioners and the certificate shall be delivered to

the secretary of the district who shall, within thirty (30) days,

cause the records of the district to be amended to exclude the area

affected.
