Evidence: identification corroborated Los Alamitos Channel CAR8456100020161109050078

Receiving water reported by facility — waterbody identification corroborated by geographic evidence.

Nearest distance from the reported facility location: 544 m. Method receiving_water/2.

2026 Integrated Report status Evidence: State-published

Los Alamitos Channel is not on the 2026 303(d) list.

Published by the State Water Resources Control Board (2026 California Integrated Report, Appendix A). Listing status is taken from Appendix A only.. 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.

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.

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.

No industrial monitoring results for this permit are in the current exports.

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.
