Okla. Stat. tit. 52, § 52-47.4: Inspection, operation and maintenance plan

A. Any person who operates or owns a hazardous liquid

available; and

2. whether the plan is appropriate for the particular

transportation system or facility; and

3. the feasibility of the plan; and

4. the extent to which said plan will contribute to public

safety.

C. If the Commission determines that a plan required pursuant

to the provisions of this section is inadequate to achieve safe

operation of a transportation system, the Commission, after notice

and opportunity for a hearing, shall require the plan to be revised.
