Whenever the agency maintaining a small works roster believes that grounds exist for denying an application for placement on a small works roster, or removing the name of a contractor from a small works roster, notice of said grounds shall be given to the contractor by first-class mail. If the contractor fails to object or request a hearing within twenty days after the mailing of said notice, then the denial or removal shall be made effective. If the contractor requests a hearing within forty-five days after the mailing of the notice, then a hearing will be conducted in accordance with chapter 34.04 RCW.
