Associations are calculated from official facility coordinates, USGS HUC12 boundaries, and official 2026 impaired-water geometry. They do not establish a discharge connection or causation.
Numeric effluent limits and action levels stated by the Water Board for this permit, with the receiving water named in the TMDL.
Receiving water named in TMDL R4 - Greater Los Angeles/Long Beach Harbor Waters
| Parameter | Limit type | Period | Basis | Limit | Due date | Reported results for parameter |
|---|---|---|---|---|---|---|
| Copper, TotalVocabulary match: Copper (narrower) | TMDL NAL | FINAL | INSTANTANEOUS | .0058 mg/L | 2032-05-05 | None reported |
| Lead, TotalVocabulary match: Lead (narrower) | TMDL NAL | FINAL | INSTANTANEOUS | .221 mg/L | 2032-05-05 | None reported |
| Zinc, TotalVocabulary match: Zinc (narrower) | TMDL NAL | FINAL | INSTANTANEOUS | .095 mg/L | 2032-05-05 | None reported |
Limit values, limit periods, parameters, TMDL names and receiving-water names are reproduced exactly as stated by the Water Board in SMARTS. California Stormwater Intelligence does not compare reported monitoring results to these limits and makes no exceedance, violation or compliance determination. Where a stated receiving-water name is linked to a 2026 303(d) waterbody, that link is a derived exact-name match, not a Water Board determination.
Self-reported industrial stormwater sampling results submitted to SMARTS.
No SMARTS monitoring results are recorded for this WDID in the statewide dataset.
YDOS-derived
Reported SMARTS analytical results compared against the Numeric Action Levels of the Industrial General Permit version in effect for each reporting year (July 1 – June 30).
No reporting year for this WDID contains samples eligible for NAL comparison. That can mean no analytical results were reported, the reported parameters have no adopted NAL, or the samples were taken at locations that are not permitted discharge points.
An NAL exceedance is a permit-defined condition that triggers Exceedance Response Actions under the Industrial General Permit. It is not a violation, an enforcement action, or a Water Board compliance determination. Annual values use the arithmetic average of eligible results with non-detects treated as zero; instantaneous maximum NALs (total suspended solids, oil and grease, pH) are exceeded when two or more eligible results in a reporting year fall outside the level.
