Receiving water

Reported by the facility Evidence: facility-reported: San Gabriel River
Discharges directly / indirectly: N / Y (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

10 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.

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.

Compliance and enforcement records by type
Record type	Records	As published	Dates	Retrieved	List
Violations	10	10 Violation · 0 Potential (preliminary) · 0 Dismissed	Jul 02, 1999 – Jul 16, 2022	Oct 21, 2026	All violations
Enforcement actions	7	7 issued · 0 draft · 0 withdrawn, rescinded or superseded	Mar 28, 2001 – Aug 02, 2022	Oct 21, 2026	All actions

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.
