To facilitate the equitable geographic distribution of conditional releases under this chapter, the department shall notify the secretary of health, or the secretary's designee, whenever a sex offender treatment provider in an underserved county has been contracted to provide treatment services to persons on conditional release under this chapter, in which case the secretary of health shall waive any fees for the initial issue, renewal, and reissuance of a credential for the provider under chapter 18.155 RCW. An underserved county is any county identified by the department as having an inadequate supply of qualified sex offender treatment providers to achieve equitable geographic distribution of conditional releases under this chapter.
