CCR High Hazard Impoundments

EPA's Comprehensive Compliance Report dated 2025-06-11 is documented by the accepted Source campaign as a nationwide, one-row-per-CCR-unit workbook. The curated subset contains 49 units at 34 plants after filtering Unit Type to Surface Impoundment and Hazard Potential Classification to High, with coordinates reported on every row. This supports parcel-centered intersection or stated-distance screening through a documented spatial match. Preserve report vintage, raw unit type and hazard class, plant and unit identity, point provenance, and distance method; do not infer impoundment geometry, contamination, violation, structural condition, failure likelihood, or organisation ownership. Refresh requires a new FOIA request rather than an API or standing download.
