Okla. Stat. tit. 63, § 63-684.8: Supplementary agreements

ARTICLE VII

Supplementary Agreements

Inasmuch as it is probable that the pattern and detail of the

machinery for mutual aid among two or more states may differ from

that among the states that are party hereto, this compact contains

elements of a broad base common to all states, and nothing herein

shall preclude any state entering into supplementary agreements with

another state or affect any other agreements already in force

between states. Supplementary agreements may include, but shall not

be limited to, provisions for evacuation and reception of injured

and other persons and the exchange of medical, fire, police, public

utility, reconnaissance, welfare, transportation and communications

personnel, and equipment and supplies.
