Evidence: identification corroborated Mono Lake CAL6010008019980806094326
Receiving water reported by facility — waterbody identification corroborated by geographic evidence.
Nearest distance from the reported facility location: 1.7 km. Method receiving_water/2.
2026 Integrated Report status Evidence: State-published
Mono Lake is on the 2026 Clean Water Act section 303(d) list (1 Appendix A decision; category 4b).
| Pollutant | Category | Listing decision | TMDL requirement | Decision ID |
|---|---|---|---|---|
| Salinity/TDS/Chlorides | 4b | Do Not Delist from 303(d) list (being addressed with action other than TMDL) | 5C | 172190 |
Published by the State Water Resources Control Board (2026 California Integrated Report, Appendix A). Listing status is taken from Appendix A only. State Board adoption 2026-02-03; USEPA approval not confirmed. A listing describes the waterbody, not this facility. Waterbody profile.
Impaired waters and TMDLs
Two kinds of information, kept apart: 2026 Integrated Report waterbodies near the reported location (geographic proximity only), and TMDL records that SMARTS lists for this facility. Neither establishes where the facility discharges; see Receiving water for the facility's own statement.
Nearby waterbodies Evidence: geographic proximity
Spatial proximity only; discharge pathway not established. Being near a waterbody does not mean the facility discharges to it.
| Waterbody (2026 Integrated Report) | Distance | 2026 303(d) list | Appendix A decisions |
|---|---|---|---|
| Lee Vining Creek CAR6010003519980804142227 | 414 m | not listed | 0 |
Waterbodies within 1.0 km of the reported facility location. Method proximity/1.
SMARTS TMDL records Evidence: SMARTS-reported
No TMDL records for this facility in the SMARTS TMDL export.
Reported monitoring results Evidence: facility-reported
Numeric Action Level (NAL) screening is being independently validated and is not shown. Nothing on this page states whether a result exceeded a NAL.

Results are shown exactly as reported by the discharger. Identical rows repeated in the State's export are shown once. Where the export contains different versions of the same sample and parameter, each version is listed and flagged. Details.
Compliance and enforcement records Evidence: SMARTS record
These are records as the State Water Board publishes them in SMARTS, with the source's own types and statuses. They are not a compliance determination or rating. A record listed here is not proof of a violation beyond what the source states, and the absence of records does not establish compliance.
| Record type | Records | As published | Dates | Retrieved | List |
|---|---|---|---|---|---|
| Violations | 4 | 4 Violation · 0 Potential (preliminary) · 0 Dismissed | Jul 02, 2011 – Jul 16, 2026 | Oct 21, 2026 | All violations |
| Enforcement actions | 4 | 4 issued · 0 draft · 0 withdrawn, rescinded or superseded | Jul 27, 2017 – Jul 22, 2026 | Oct 21, 2026 | All actions |
| Inspections | 1 | inspections, not findings | Aug 08, 2019 – Aug 08, 2019 | Oct 21, 2026 | All inspections |
| Annual reports | 10 | certified reports (contents not shown) | 2015 – 2025 | Oct 21, 2026 | All reports |
| Water-quality-based corrective action reports | 0 | reports, by parameter | — | Oct 21, 2026 |
Each record type is counted by its own SMARTS identifier. A violation and the enforcement action that cites it are two records in two lists; they are never added together.

How to read the evidence labels
- Evidence: SMARTS record Evidence: facility-reported Information as published in SMARTS or reported by the discharger.
- Evidence: identification corroborated The reported receiving-water name identifies one official waterbody and the facility's location is consistent with it. It does not establish a discharge pathway.
- Evidence: candidate, awaiting review Evidence: not confirmed The reported name could match one or more official waterbodies, but no identification has been confirmed; nothing is assigned without review.
- Evidence: spatial Evidence: geographic proximity Derived from the reported location only.
- Evidence: SMARTS-reported Source records whose links to official references are not yet reviewed.
- Evidence: unavailable The information could not be loaded or is not in the sources.
Records are shown as published and are not compliance determinations. How geographic context is derived.
