Progress reports must be submitted to the department annually on September 1 after the due date of the plan. The purpose of the progress report is to provide information on quantities of hazardous waste and hazardous substances or products containing hazardous substances reduced in the prior twelve-month period.

(1) Progress reports shall include a discussion of:

(a) Performance goals. If numeric performance goals were listed in the plan, progress toward achieving these goals must be discussed. If numeric performance goals were not listed in the plan, progress made toward establishing numeric goals and progress made toward achieving the goals as stated in the plan must be discussed. This discussion shall include:

(i) A description of reduction, recycling, and treatment opportunities that were implemented.

(ii) A description of the process or processes impacted by each opportunity.

(iii) A description of the quantities, by weight, of hazardous substances or products containing hazardous substances reduced and hazardous waste reduced by each option. Estimation techniques, and any assumptions used must be described. Quantities reduced must be displayed in relation to changing production levels. The description shall also include a statement of the level of production or service activity in relation to the level of production or service activity stated in the plan at the time the plan was prepared.

(iv) If measurement or estimation techniques are changed from the prior reports in such a way that reductions are not additive for the five-year planning period, a methodology for converting prior reported reductions must be described and recalculations must be provided.

(b) Problems encountered in the implementation process. Problems must be clearly identified and must include a discussion of steps taken or proposed to resolve problems. An update on problems reported in previous progress reports must be included.

(2) Upon the request of two or more users or generators belonging to similar industrial classifications, the department may aggregate data contained in their annual progress reports for the purpose of developing a public record.
