Okla. Stat. tit. 27A, § 27A-2-6-501.2: Sludge management land application plan

A. Any permit application received by the Department on or

after July 1, 1993, for a discharge permit, a municipal or

industrial wastewater construction or treatment permit or a public

water supply permit shall include or provide for a sludge management

plan if the applicant proposes the beneficial use of such sludge or

wastewater through land application.

B. Any permittee proposing the land application of wastewater

or sludge under the terms of an existing Department issued municipal

or industrial construction or wastewater treatment permit, a

discharge permit or a water supply permit, must receive the

Department's approval on a sludge management plan. Adding a sludge

management land application plan to an existing individual

industrial discharge permit or an industrial wastewater treatment

permit issued by the Department shall require the major modification

of the existing permit. For purposes of this section, permits

issued by the Oklahoma Water Resources Board and the State

Department of Health prior to June 30, 1993 shall be deemed issued

by the Department upon the transfer of such permits to the

Department effective July 1, 1993.

C. Sludge management plans for the land application of sludge

or wastewater which have been approved by the Department may be

modified or amended by the Department pursuant to rules promulgated

by the Board.

D. Any use or final disposition of sludge other than land

application shall require the approval of the Department pursuant to

rules promulgated by the Board.
