authorization "The permittee is authorized to discharge from the following combined sewer overflows (CSOs) only during wet weather periods when the flow in the sewer system exceeds the capacity of the sewer system."
outfalls
- - station 2PD00009002
  - location Mercer Road Diversion Chamber
  - receiving_stream Poe Ditch
level_of_control "The permittee shall discharge no more than four untreated combined sewer overflow (CSO) events per typical year. This level of control is based on the City of Bowling Green's Combined Sewer Overflow Long Term Control Plan (LTCP), which was approved by Ohio EPA in March 2008. The City completed the LTCP and submitted the Wet Weather Characterization Report on January 1, 2015, which concluded that the City had met the goals of the LTCP. The City must maintain compliance with the LTCP level of control."
lake_erie_basin_public_notification Part II, Item G imposes signage, local-health-department notification, public notification and an annual report specifically because these CSOs discharge to the Lake Erie Basin.

- note_other B2EHP and the lower summer/winter ammonia limits also first apply here. The full final set matches Table 15 of the fact sheet; see data/extracted/oepa/bowling-green/2PD00009.fs.npdes.yaml rather than duplicating it.

subject Final Effluent Limits for Ammonia, B2EHP, and MBAS
preamble "New final effluent limits are proposed for bis(2-ethylhexyl) phthalate (B2EHP), and methyl blue activated substances (MBAS). Also, lower final effluent limits are proposed for ammonia (summer and winter). The permittee shall attain compliance with the effluent limits for ammonia, B2EHP, and MBAS as expeditiously as possible but no later than the dates in the following schedule."
milestones
- - month 12
  - due 2023-05-01
  - event_code 07099
  - requirement Progress report to Ohio EPA Northwest District Office (NWDO) including five years of influent/effluent/sludge data for ammonia, B2EHP and MBAS; a list of significant and non-significant industrial users; actions taken in the previous 12 months; actions planned for the next 12.
- - month 24
  - due 2024-05-01
  - event_code 07099
  - requirement Second progress report, same contents.
- - month 36
  - due 2025-05-01
  - event_code 05699
  - requirement "As soon as possible but no later than 36 months after the effective date of this permit, the permittee shall attain compliance with the new effluent limits for ammonia, B2EHP, and MBAS. The permittee shall notify Ohio EPA NWDO within seven days of attaining compliance."
due_date_note The calendar dates in `due` are [inference] — computed from the 2022-05-01 effective date; the permit states only the month offsets. Whether the two progress reports and the compliance notification were actually submitted is NOT established by any captured source. [open] — a records request to Ohio EPA NWDO for the 07099 and 05699 submittals would settle it, and would speak directly to what the plant knew about its MBAS position before the limit took effect.
other_schedules
- phosphorus_optimization Part I.C.B — the permittee must complete and submit the "Evaluation for Reducing Discharge of Phosphorus" form with its next NPDES renewal application.
- municipal_pretreatment Part I.C.C — evaluate the adequacy of local industrial user limitations, submit a revised local limit technical justification report, and implement revisions if needed. Relevant to any new significant industrial user in the service area.

percent_removal Item M — "The treatment works must obtain at least 85 percent removal of carbonaceous [BOD5 and TSS]."
reopener Item N — "Water quality based permit limitations in this permit may be revised based on updated [information]." A reopener exists; nothing in the captured record shows it used.
weekend_monitoring Item C — all parameters except flow "need not be monitored on days when the plant is not normally staffed (Saturdays, Sundays, and Holidays)." Report "AN" on those days. Worth carrying: a daily-maximum limit is only sampled on staffed days, so the reported daily maxima are not a seven-day-per-week record.
ssos Item H — SSO reporting, including a separate track for SSOs that imminently and substantially endanger human health.

⚠ Gaps in the record

THE LIMIT TABLE YOU WANT DEPENDS ON THE DATE. Part I.A carries TWO complete limit tables for the same outfall. Item 1 governs "the period beginning on the effective date of this permit and lasting through the 36th month"; Item 2 governs "the period beginning on 37th month after the effective date of this permit and lasting until the expiration date." The interim table has NO MBAS limit and NO B2EHP limit, and its ammonia limits are looser (winter 7.3/4.8 mg/L, summer 2.7/1.8 mg/L). Reading the final table against a 2023 DMR, or the interim table against a 2026 DMR, produces a wrong answer in both directions.
The permit itself never prints a calendar date for the interim/final changeover — it is expressed only as "the 36th month" and "37th month after the effective date." With an effective date of 2022-05-01 that resolves to on or about 2025-05-01. ICIS-NPDES independently carries the interim limit set as ending 30-APR-25, which agrees. Both are recorded; the arithmetic is [inference] and the ICIS date is [verified] as what the federal system holds. See data/extracted/bowling-green/water-watch.yaml, which turns on this date.
Ambient stations 801 and 901 monitor the NORTH BRANCH PORTAGE RIVER, not Poe Ditch. The permit's own upstream/downstream biology and chemistry are therefore measured a stream removed from the outfall's immediate receptor. Poe Ditch itself is not monitored under this permit at all.
