The committed PDF has 42 pages; the permit's own printed "Total Pages: 42" (sheet 1) AGREES. No discrepancy — every printed sheet 1 through 42 was read.
renewal_application_due
The permit's own text requires the renewal submission "no later than 180 days prior to the above date of expiration" — i.e. on or about 2025-06-03 for the 2025-11-30 expiration. [inference] from the permit's stated rule; the permit prints no calendar date for it. (This corpus separately holds the 2025-cycle renewal application, eDoc 3832476, filed 2025-05-29 — before that computed date — but that document is out of scope for this extraction; see meta.not_in_this_corpus_scope.)

- sso_300
- section 1
- parameter Overflow Occurrence (74062), No./Month, 1/Month Total
- note The permit is explicit that the 1/Month frequency is a REPORTING frequency, not a monitoring one: "these overflows shall be monitored on each day when they discharge." Only SSOs that reach waters of the state — directly or through a storm sewer — are reported at this station. Each location overflowing on a given day counts as one occurrence, so a two-location day is two. "All sanitary sewer overflows are prohibited."
- annual_report An annual SSO report covering ALL overflows in the collection system (including those that never reach waters of the state) is due March 31 for the prior calendar year, with SSO locations numbered consecutively from 301, volumes in millions of gallons, and a narrative analysis of water-in-basement (WIB) patterns by location, frequency and cause. Adequate public notice of the report's availability is required (posted notices, newspaper notice, or a notice with sewer bills).

Reported as monitor-only, no limits.
- note Sampling for temperature, pH, ammonia, nitrate+nitrite, TKN, TP and E. coli shall occur the same day as at outfall 1PD00011001.
- significance The upstream ambient toxicity battery runs on the SAME single annual September schedule as the outfall's own monitor-only toxicity parameters (see effluent_limits_001) — the two are timed together, even though neither carries a numeric limit. Contrast the Mansfield precedent, where the ambient tests ran at a different frequency (2/Year) than the outfall's own.
- transcription_note Sheet 11 prints parameter 61435 as "Pimephales promela" — no terminal "s" — while 61441 on the same sheet prints "promelas". Silently normalized to "promelas" above (ambient_toxicity); the document's own inconsistency, recorded here rather than transcribed literally in the parameter list.

- note Sampling for the respective/common parameters shall occur on the same day as Outfall 1PD00011001.
- significance 801 + 901 together are a committed monthly upstream/downstream nutrient record on the Mad River, arriving through DMRs for the life of the permit (to 2025-11-30). It is an ambient dataset the City is obliged to produce, not one anybody has to go collect.

- requirement Evaluate the adequacy of local industrial user limitations to prevent pollutants entering the POTW that would interfere with its operation, pass through in amounts exceeding water quality standard-based limits, be incompatible with the POTW, or limit wastewater/sludge use options. Submit either a technical justification for REVISING local limits (with a pretreatment program modification request) or a technical justification for RETAINING the existing ones, following Ohio EPA's/USEPA's local limits guidance.
- pollutants_requiring_justification Arsenic, cadmium, total chromium, dissolved hexavalent chromium, copper, free cyanide, lead, mercury, molybdenum, nickel, selenium, silver and zinc — "unless screening of wastewater and sludge indicate these pollutants are not present in significant amounts" — plus any other pollutant where a local limit may be necessary to protect against pass through, interference or sludge disposal.

PE stamp and signature (if new or revised limits proposed).
- engineering_requirement If new or revised industrial user discharge limits are proposed, the report requires "the stamp and signature of a licensed Ohio professional engineer."
- sampling_methods a. Mercury — if EPA Method 245.1/245.2 shows below-detection domestic background concentrations, the permittee shall use EPA Method 1631 or 245.7 to quantify domestic background mercury contributions. b. Free Cyanide — the permittee shall use ASTM D7237, OIA-1677-09, or ASTM D4282-02 (the latter requiring supporting "sufficiently sensitive" documentation under 40 CFR 122.44(i)(1)(iv)).

- submit_to "One copy to the Ohio EPA Southwest District Office and one copy to: Ohio EPA, Division of Surface Water, NPDES Permit Unit, P.O. Box 1049, Columbus, OH, 43216-1049."
- requirement Prepare and submit for acceptance a Phosphorus Discharge Optimization Evaluation plan — an evaluation of collected effluent data, possible source reduction measures, operational improvements and minor facility modifications that will optimize reductions in phosphorus discharges from the WWTP, including a proposed schedule for implementing any recommended measures. Upon Ohio EPA's acceptance, the permittee shall implement the plan; a complete PTI application may be required. Also requires completing the "Evaluation for Reducing Discharge of Phosphorus Form" alongside a future permit renewal application.

- what_is_not_established WHETHER EITHER WAS FILED. Nothing in this document establishes that — no submittal, no acknowledgment, no violation notice, and no ECHO/ICIS extract is transcribed here. "Past due" means the date has passed, NOT that the City missed it. This is not to be written as a missed deadline.
- how_to_close_it A public-records request to Ohio EPA for the 52599 and 01299 submittals under permit 1PD00011 / OH0027880 would settle both.

- bypass_trigger NONE. This permit has no equalization-basin bypass station and Part II contains no bypass-trigger item comparable to the Mansfield precedent's Item V. See warnings[2] and warnings[8] (only Item Y, industrial storm water, addresses a related but distinct topic).
- biomonitoring_program
- item X. Biomonitoring Program Requirements (sheet 27)
- text "The permittee shall continue to implement an effluent biomonitoring program to determine the toxicity of the effluent from outfall 1PD00011001." Single outfall, so — unlike the Mansfield precedent's 001/002 station disagreement — there is no ambiguity about which stream this program tests.
- testing Annual chronic bioassays (Ceriodaphnia dubia and Pimephales promelas) and annual definitive acute bioassays (same species) for the life of the permit, per Ohio EPA's "Reporting and Testing Guidance for Biomonitoring", July 1998 (or current revision). "Acute toxicity tests need not be performed for months in which chronic toxicity tests are conducted" — acute endpoints are then derived from the chronic test. Ambient (upstream, station 801) testing runs alongside. The SOP (or verification of SOP submittal) was due no later than three months after the effective date — on or about 2021-03-01 [inference].
- definitions TUa = Acute Toxicity Units = 100/LC50. TUc = Chronic Toxicity Units = 100/IC25 (or, for Ceriodaphnia dubia outside the mixing zone when more restrictive, 100/sqrt(NOEC x LOEC)).

- coverage_note Sheets 30-42 (32 numbered general conditions, roughly 31% of this 42-sheet instrument) were read as part of the pdf_page_count_check full-document pass but are Ohio EPA's standard NPDES boilerplate, not facility-specific terms, and are deliberately NOT indexed item-by-item in this file. The one exception already transcribed above is Item 12 (Noncompliance Notification, sheets 36-37) — see warnings[6] — because its six-office routing list bears directly on the Southwest District Office finding. No other Part III item (e.g. bypass provisions, permit conditions, definitions, severability) is summarized here; consult the source PDF directly for its text.
⚠ Gaps in the record
- THIS PERMIT ESTABLISHES NO NUMERIC WHOLE-EFFLUENT-TOXICITY (WET) LIMIT ANYWHERE. All four toxicity parameters at the outfall (61425/61426 Ceriodaphnia dubia acute/chronic, 61427/61428 Pimephales promelas acute/chronic — sheet 3, Part I.A) are MONITOR ONLY, 1/Year in September, with no maximum or loading value printed. The four parallel ambient tests at the upstream station (61432/61435/61438/61441 — sheet 11, Part I.B.6) are likewise monitor-only, reported as "% Affected". Consistent with that, Part I.C (Schedule of Compliance, sheets 13-15) contains NO Toxicity Reduction Evaluation — only a pretreatment local-limits schedule and a phosphorus-optimization schedule. The permit does name the mechanism by which a WET limit could arrive: Part II Item X.4.a (sheet 28) states "Based on Ohio EPA's evaluation of the results, this permit may be modified to require additional biomonitoring, require a toxicity reduction evaluation, and/or contain whole effluent toxicity limits." This is a materially simpler permit than the Mansfield precedent on this axis: nothing here is currently driving toward a WET limit, but the permit itself preserves the path to one.
- THIS PERMIT ESTABLISHES NO NUMERIC PHOSPHORUS LIMIT. 00665 Phosphorus, Total (P) is monitor-only (1/Week 24hr Composite, sheet 2) — no maximum, no weekly/monthly concentration or loading value. The only phosphorus-related obligation is Part I.C.B's "Evaluation for Reducing Discharge of Phosphorus" (sheet 15), a planning submittal, not an effluent limit.
- PART I.B'S OWN SECTION NUMBERING SKIPS "3.": 1. SSO Monitoring (station 300, sheet 4), 2. Sludge Monitoring (station 581, sheet 5), then the next section is numbered "4. Sludge Monitoring" (station 586, sheet 8), followed by 5. Influent (601, sheet 9), 6. Upstream (801, sheet 11), 7. Downstream-Nearfield (901, sheet 12). No section "3." exists anywhere in the 42 pages (confirmed by a full-text search). Part II Item B's station table (sheet 17) independently corroborates the same absence: it lists exactly seven stations — 001, 300, 581, 586, 601, 801, 901 — with NO 588 (sludge transfer to another NPDES permit holder), and NO 602/603 (equalization-basin bypass / stormwater) station of any kind. A full-text search of the extracted PDF for "588", "1PD00011602" and "1PD00011603" returns zero hits. The numbering gap is consistent with a permit template that drops an unused station (588 would have been item "3.") without renumbering what follows — that explanation is [inference]; the gap and the absence of those station IDs are [verified] directly from the document.
- NOTE "a" UNDER THE OUTFALL 001 TABLE (sheet 3) PRINTS "LEAD" TWICE: "Cadmium, copper, lead, total chromium, lead, nickel, and zinc- See Part II, Item L." Transcribed verbatim; this is the document's own typo, not normalized away.
- THE PRINTED DMS COORDINATE FOR STATION 1PD00011001 (sheet 17: Lat 40°N 05' 46", Long 83°W 47' 50" → converted here to 40.096111, -83.797222, [inference], see sampling_stations.'1PD00011001'.coordinate_note) differs slightly from the coordinate this repo's data/documents/oepa/urbana/README.md and filename-map.yaml record for the same outfall (40.095278, -83.797222), which is sourced from the 2025 renewal application (eDoc 3832476) — a different, out-of-scope document, not transcribed here. Both name the same physical outfall to the Mad River. The two figures are not reconciled by this extraction; doing so would require reading eDoc 3832476 itself.
- THE PERMIT NEVER CALLS ITSELF A "MODIFICATION" OR A "RENEWAL" ANYWHERE IN ITS OWN TEXT — the sheet 1 header carries only "Issue Date / Effective Date / Expiration Date" labels with no qualifying word, and the word "renewal" appears three times elsewhere in the document but never in reference to this permit's own issuance (once about the NEXT renewal application, twice in unrelated definitions). `permit_action` below is therefore [reference], drawn from this corpus's filename-map.yaml annotation (which calls it "Issued NPDES permit ... 2020 renewal cycle"), NOT [verified] from the face of the permit.
- ALL "NORTHWEST"/"NORTHEAST"/"CENTRAL" DISTRICT-OFFICE MENTIONS IN THIS PERMIT (4 each) are the generic six-office contact list, which is printed FOUR times, not once — under both Part III Item 12.A (Exceedance of a Daily Maximum Discharge Limit) and Item 12.B (Other Permit Violations), each giving the list once by e-mail and once by phone (sheets 36-37) — that Ohio EPA prints in every NPDES permit regardless of which office actually holds the file. "Southwest" appears 10 times total in this document — a correct raw count, but only 6 of those are a SUBSTANTIVE routing instruction specific to this facility; the other 4 sit inside that generic list. The 6 substantive mentions are: the pretreatment local-limits schedule (Part I.C.A, sheet 13); the phosphorus optimization plan (Part I.C.B, sheet 15 — named twice, once for the plan copy and once for the follow-on PTI application); the operator-of-record backup-request provision (Part II.A.2.d, sheet 16); the 5-day written follow-up report for an SSO that may imminently and substantially endanger human health (sheet 18); and the annual SSO report hardcopy (sheet 20). All 6 name the SOUTHWEST District Office, consistently. Unlike the Mansfield precedent, this permit does not disagree with itself about which office to address.
- THE AUTHORIZATION SENTENCE NAMES THE RECEIVING WATER DIRECTLY: sheet 1 reads "... wastewater treatment works located at 1263 Muzzy Road, Urbana, Ohio, Champaign County and discharging to Mad River in accordance with the conditions specified in Parts I, II, and III of this permit." No river mile is printed anywhere in this permit (a full-text search for "River Mile" and "RM " returns zero hits) — unlike the Mansfield precedent, which named a river mile but omitted the water's name. Recorded here because the mansfield precedent's structure expects this line to be checked, not because this document has a defect on it.
- THIS PERMIT LISTS ONLY THREE PARTS ("Parts I, II, and III") IN ITS OWN AUTHORIZATION SENTENCE, not six. There is no Part IV/V/VI (SWPPP/stormwater) content anywhere in this document — consistent with the facility having no bypass (602) or stormwater (603) outfall station and the industrial stormwater "No Exposure Certification" (Part II Item Y) being handled as a single paragraph rather than a dedicated set of parts. [reference] Per data/documents/oepa/urbana/README.md, the City's separate MS4 stormwater program is regulated under permits OHQ000003 / 1GQ00062 — neither permit number appears anywhere in this document (0 occurrences, verified); these are different documents outside this task's scope.
- THE STORM WATER "NO EXPOSURE CERTIFICATION" RECERTIFICATION DEADLINE HAS PASSED. Part II Item Y (sheet 28) states the permittee's "No Exposure Certification" (number 1GRN00960*AG) was signed 2020-06-30 and "must be re-affirmed every five years... No later than June 30, 2025, the permittee must submit a new form." As of 2026-08-26 that date is over a year past. Nothing in this single document establishes whether a new certification was filed — that is `[open]`, not a finding of noncompliance.
