Rural health care service arrangements existing on March 29, 1990, may continue in full operation only so long as they comply with all of the following:

(1) Within ten days following March 29, 1990, all rural health care service arrangements shall inform the insurance commissioner of their intent to apply for approval to operate as an entity authorized under chapter 48.44 RCW or intend to merge with an entity authorized under Title 48 RCW or merge with an entity defined in this section;

(2) The arrangement submits an application for approval as an entity authorized under chapter 48.44 RCW by May 1, 1990;

(3) The arrangement has one hundred thousand dollars on deposit with the insurance commissioner by July 1, 1990;

(4) The arrangement has one hundred fifty thousand dollars on deposit with the insurance commissioner by September 1, 1990; and

(5) The arrangement complies with all reasonable requirements of the insurance commissioner excluding the deposit requirement, except as outlined in this section.

If such rural health care service arrangements fail to comply with any of the above requirements, or if during the application process an entity engages in any activities which the insurance commissioner reasonably determines may cause imminent harm to consumers, the entity may be subject to appropriate legal action by the insurance commissioner pursuant to the authority provided in Title 48 RCW.

A rural health care service arrangement which comes into compliance with Title 48 RCW through the method outlined in this chapter shall be subject to all applicable requirements of Title 48 RCW except that the deposit requirements shall not be increased until May 1, 1991.
