Known gotchas
Biosolids Annual Report data is reported annually by permittees, so it is far lower-frequency than DMR-based wastewater compliance data
Biosolids facility and annual-report searches are separate filtered views layered on the same CWA/ICIS-NPDES facility search REST service, not standalone endpoints
Biosolids (sewage sludge) regulation under 40 CFR Part 503 has its own compliance categories distinct from standard NPDES effluent violations; don't conflate the two when interpreting 'violation' fields
