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 Rhine Channel area of Lower Newport Bay
| Parameter | Limit type | Period | Basis | Limit | Due date | Reported results for parameter |
|---|---|---|---|---|---|---|
| Copper, TotalVocabulary match: Copper (narrower) | NEL | FINAL | INSTANTANEOUS | .00578 mg/L | 2020-07-01 | 28 results · latest 2026-02-17 |

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.

Monitoring rows are official self-reported SMARTS submissions, joined to this facility by WDID. California Stormwater Intelligence does not restate, correct, average or evaluate reported values, and no benchmark comparison or violation determination is made.
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).
| Parameter | NAL type | Calculated value | NAL | Result | Samples used | Method |
|---|---|---|---|---|---|---|
Copper, Total Recoverable copper_total | Annual | 0.003 mg/L | 0.033 mg/L | At or below NALAnnual average of 6 eligible result(s) compared with the annual NAL.0.08× threshold | 6 eligible2 non-detect as zero | arithmetic mean of all eligible effluent results in the July 1 - June 30 reporting year (censored results assigned zero only where MDL and ML were both reported) |

Zinc, Total Recoverable zinc_total | Annual | 0 mg/L | 0.26 mg/L | At or below NALAnnual average of 6 eligible result(s) compared with the annual NAL.0× threshold | 6 eligible6 non-detect as zero | arithmetic mean of all eligible effluent results in the July 1 - June 30 reporting year (censored results assigned zero only where MDL and ML were both reported) |
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.
