APPENDIX D —ANNUAL REPORT QUESTIONS FOR MODERATE LOADERS Permittees are required to submit annual reports online, pursuant to Special Condition S9.D. 1. Did your facility stay below the Action Level in S5.b, Table 8 or Table 9 for the jurisdiction with a bubbled action level? (S5.C.2.b.i) a. Attach a document listing the contribution of each of your individual facilities to the total bubble allocation for the reporting period. (S5.C.2.b.i) 2. Did your facility stay below a 10 mg/L annual average TIN concentration? (S5.C.2.b.i) (If Q1 =Y and Q2 = Y, then no further questions). 3. Attach a document describing the assessment method applied to evaluate the existing treatment process. (S5.C.1.a) 4. What is your pre-optimization TIN removal rate, expressed as a percentage? (S5.c.1.a.i) 5. Attach a document explaining your initial approach for optimization. (S5.C.1.a) 6. Did you maintain and/or update your assessment approach after year 1?(S5.C.1.a.ii) 7. Do viable optimization strategies exist for your current treatment process? (S5.C.1.b) 8. Did all of the potential optimization strategies you identified and evaluated for S5.C.1.b have a reasonable implementation cost and timeframe? (S5.C.1.b) 9. ATTACH a document describing your preferred optimization strategy for implementation in 2022 (selection due July 1) (S5.C.1.c) 10. What is the expected performance for the selected optimization strategy? (S5.C.1.c) 11. Attach a document describing optimization plan implementation including start date, schedule for full implementation, initial costs, and challenges including impacts to other measures of treatment plant performance. (S5.C.2.a) 12. What TIN removal rate was observed during the reporting period? (S5.C.2.b.ii) 13. Attach a document describing your ongoing investigations to reduce influent TIN loads from septage handling practices, commercial, dense residential and industrial sources. (S5.C.3.a, S5.C.3.b) 14. (If Q1=N and Q7 = Y) Attach document including: factors causing the WWTP to not meet the optimization goal, whether modifications to the strategy could improve performance, and whether a different strategy or combination of strategies may be more appropriate. Also, document changes to the optimization strategy either thorough the selection of the new optimization strategy and new performance metric or existing implementation refinement. Revise the expected performance if electing to keep the existing strategy. Provide rationale for no changes if Permittee proposes no changes to the optimization strategy (S5.D.1.a and S5.D.1.b) 15. (If Q1 = No and Q7 = No) Attach abbreviated engineering report or technical memo (due 12 months after documenting action level exceedance or determination that no optimization strategies exist).
