The department will periodically evaluate the content of the SMP with knowledgeable research and technical persons to determine whether the program is meeting the objectives of Title 80, chapter 15, MCA. The department in cooperation with research, technical and interested persons, users of agricultural chemicals, members of any appointed advisory committee and the public will develop and use specific evaluation criteria for determining the effectiveness of the SMP. The initial evaluation will be made after two years, following which additional evaluations will be made as needed. When substantial changes are necessary, the department will determine what elements of the plan need to be revised to ensure compliance with Title 80, chapter 15, MCA. The department may hold public meetings to assist in making evaluations. The department will follow the procedures in ARM 4.11.304 throughout this evaluation process. The department will also evaluate the SMP through the provisions set forth in ARM 4.11.903.
