(1) An agency or organization may accept such designations due to the lack of alternative agencies or organizations in the service area; or
(2) An agency or organization has applied to and been authorized by the Oregon Health Authority to operate a demonstration project that combines screening interviews and treatment programs. The authority shall by rule set forth the conditions under which a demonstration project may be authorized.
