PROJECT RANKING Projects will be ranked based upon points accumulated under the Rule 6 rating process. The Director shall not place projects on the priority list and shall remove projects from the list when it is determined that the projects will not contribute to achieving applicable state water quality goals, policies, standards, or objectives. RULE 8. REVIEW AND ADOPTION OF PROJECT PRIORITY LIST The Director shall hold a public hearing annually on the proposed priority list prior to adopting and filing the final priority list with the Secretary of State. Public notice of the availability of the proposed list and place and time of the public hearing shall be published in a newspaper of the State with statewide circulation at least thirty (30) calendar days, or as required by RIGL 42-35, in advance of the hearing to afford all interested persons reasonable opportunity to submit data, views, or arguments concerning the proposed priority list. The public notice shall indicate the location where copies of the draft priority list may be obtained and/or reviewed by interested parties prior to the hearing. The Director shall accept written comments on the draft priority list from the time of public notice of availability until seven (7) calendar days following the public hearing. The Director shall consider fully all written and oral submissions respecting the proposed rule, and make any changes deemed necessary to serve the purposes of these regulations. The Director will adopt a final priority list and file it with the Secretary of State. Upon adoption of the final priority list, if requested to do so by an interested person, the Director will issue a concise statement of the principal reasons for and against its adoption, incorporating therein the reasons for overruling the considerations urged against its adoption. The effective date of the adopted priority list will be twenty (20) days following the filing with the Secretary of State. The Director shall permanently retain a copy of the priority list hearing record which should include a copy of the final priority list filed with the Secretary of State, the transcript of the public hearing, copies of all comments, and any statement by the Director regarding the comments on or adoption of the final project priority list.
