Official facility coordinate plotted against the associated Final 2026 Integrated Report impaired-water geometry.
Geometry shown is limited to waterbodies geographically associated with this facility. Geographic association does not establish a discharge connection, receiving-water connectivity, or causation.
Intelligence summary
What is available for this facility across the connected datasets.
Official
303(d) context
Grouped by derived geographic association class.
River & Stream · Integrated Report category 5 · TMDL required
Listed pollutants / stressors (4) Indicator Bacteria, Oil and Grease, Selenium, Zinc
Lake & Reservoir · Integrated Report category 5 · TMDL required
Listed pollutants / stressors (2) DDT (Dichlorodiphenyltrichloroethane), Mercury
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 - Coyote Creek and its tributary/ies
| Parameter | Limit type | Period | Basis | Limit | Due date | Reported results for parameter |
|---|---|---|---|---|---|---|
| Zinc, TotalVocabulary match: Zinc (narrower) | NEL | FINAL | INSTANTANEOUS | .158 mg/L | 2020-07-01 | 18 results · latest 2025-02-13 |
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).

YDOS-derived overlap
Parameters where this facility has an NAL exceedance in at least one reporting year and the geographically associated waterbody carries a 303(d) listing for the same pollutant.
ZincMonitoringAbove NAL303(d) impairmentCoyote Creek, North Fork
2 reporting years above the annual NAL, most recently RY 2024 · 1 303(d) listing · 1 stated TMDL requirement · association: derived nearby in watershed (high confidence)
Overlap is informational co-occurrence between a derived NAL comparison and an official 303(d) listing. It is not evidence that this facility caused or contributed to the impairment.
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.
