APPENDIX E — ONE TIME REPORT QUESTIONS FOR SMALL LOADERS Permittees are required to submit the single report online, pursuant to Special Condition S9.E. 1. Attach a document describing your initial assessment process, your optimization goal, the list of prioritized optimization strategies identified, and the strategy implemented in 2022 (S6.B.1.b). If any optimization strategies were found to not have a reasonable implementation cost or timeframe (S6.B.2.a.iv), include description of the feasibility and cost analysis that led to exclusion of any approach(es). (S6.B.1.a, S6.B.1.b) 2. Did your plant meet or exceed the pre-optimization empirical TIN removal rate in each year of this permit and also maintain or reduce TIN loads? If no, attach a document describing how you revised your optimization strategy in response to the evaluation in each of the prior permit years, and document your adaptive management steps, your assessment process, and the new optimization strategy or strategies you identified, and your updated optimization goal(s) and performance metric(s). (S6.B.2.b.ii, S6.B.2.c) 3. Did your facility stay below a 10 mg/L annual average TIN concentration? (S6.B.2.b.i) (If Q2 =Y and Q3 =Y, then no further questions) 4. What is your pre-optimization empirical TIN removal rate? (S6.B.1.a.i) 5. Did you maintain you reassessment approach after year 1? If no, attach a document describing assessment revisions that occurred each year over the permit term. (S6.B.1.a.ii) 6. What is your expected TIN removal with the preferred optimization strategy? (S6.B.1.b) 7. Attach a document describing optimization implementation including costs, time for full implementation, start date, challenges, and impacts to treatment performance. (S6.B.2.a) 8. What was the TIN removal rate observed each year during the reporting period? (S6.B.2.b.ii) 9. Attach a document describing your ongoing investigations to reduce influent TIN loads from septage handling practices, commercial, dense residential and industrial sources. (S6.B.3) 10. Did you submit the required AKART analysis on or before 12/31/2025? If no, date document was or will be provided. (S6.C) 11. Did you submit discharge monitoring reports according to the required schedule? If no, attach a document describing the missed monitoring activities and the corrective action taken. (S7, S9.A) 12. Are you retaining all applicable records? If no, attach a document descripting the missing records and the corrective action taken and/or planned. (S9.F) 13. Did you follow non-compliance notification requirements? If no, attach a document describing the non-compliance and the corrective actions taken and/or planned.
