Receiving water
- Reported by the facility Evidence: facility-reported
- Pacific Ocean
- Discharges directly / indirectly
- Y / N (as answered in the permit application)
Evidence: not confirmed Evidence: candidate, awaiting review Awaiting review
Receiving-water text as reported by the discharger in SMARTS; no waterbody identification has been confirmed.
Why it is not confirmed (1)
- C1 name is only a prefix of official names
290 official waterbodies share this name; none is assigned without review.
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.
No 2026 Integrated Report waterbody lies within the proximity threshold of the reported location.
SMARTS TMDL records Evidence: SMARTS-reported
SMARTS TMDL record as reported for this facility; it is not a determination that the TMDL applies to the facility.
| TMDL | Waterbody (as reported) | Parameter | Limit | Type | Period | Due | Discharges to TMDL water |
|---|---|---|---|---|---|---|---|
| Los Angeles River Nitrogen TMDL | Los Angeles River (below LA-Glendale WRP) | Ammonia, Total (as N) | 8.7 mg/L | NEL instantaneous | FINAL | 2020-07-01 | Y |
1 record. Links between these records and specific TMDL projects or listed waterbodies have not been reviewed and are not shown.

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 | Sep 04, 2020 – Feb 21, 2024 | Oct 21, 2026 | All violations |
| Enforcement actions | 4 | 4 issued · 0 draft · 0 withdrawn, rescinded or superseded | Sep 04, 2020 – Apr 10, 2024 | Oct 21, 2026 | All actions |

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.
