Hydrologic
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 (12) Aluminum, Anatoxin-A, Benthic Community Effects, Microcystins, Oxygen, Dissolved, Saxitoxins +6 more
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.
Water Board-stated TMDL waste load allocations applied to this industrial permit in SMARTS.
No SMARTS TMDL requirement is recorded for this WDID. In the statewide TMDL export only permits in Regions 4, 8 and 9 currently carry industrial TMDL requirements, so an absence here is not a statement that the facility discharges to an unimpaired water.
Official monitoring
Self-reported industrial stormwater sampling results as submitted by the discharger to SMARTS.

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).

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.

Enforcement
Enforcement actions as recorded by the State Water Board for this permit, in the source system's own terminology.
Structured enforcement records are not yet connected for this site. The absence of a record is not a finding about this facility.
Reporting
Annual report and Exceedance Response Action information as stated by the source system, distinguished from what is inferred from document metadata.
Annual report documents on file
DerivedYears are YDOS-derived from attachment metadata. A gap means no annual-report document was identified for that year in the attachment index — it is not a finding that a report was not filed.
Recent activity
New or changed source records this platform detected for this permit, newest first.
No source change has been detected for this permit yet. Change detection begins from the date each dataset was first indexed.
