567—101.6 (455B,455D) State volume reduction and recycling goals. The goal of the state is to reduce the amount of materials in the waste stream existing as of the July 1, 1988, baseline, 25 percent by July 1, 1994, and 50 percent by July 1, 2000, through the practice of waste volume reduction at the source and through recycling. The updated goal progress calculations provided by the department for each planning area shall be used by the department in reporting to the general assembly on the state’s progress toward meeting the 25 and 50 percent goals. If at any time the department notifies the planning agency in writing that the planning area has failed to meet the 25 percent waste volume reduction and recycling goal, at a minimum, the solid waste management techniques listed in Iowa Code section 455D.3(4) and subrule 101.13(8) must be implemented throughout the planning area. The specific methodology for determining goal progress is outlined in rule 567—101.7(455B,455D).
