EPCRA Tier II Compliance Aggregator
Automates the cross-referencing of on-site chemical volumes against federal 'Extremely Hazardous Substance' (EHS) lists for mandatory EPA Tier II reporting.
The Problem
EPA EHS lists are dynamic; state-level CAS thresholds shift without warning. A facility might be fine on Monday but non-compliant by Friday if the aggregate volume of a specific chemical on-site crosses the 'Threshold Planning Quantity' (TPQ).

Logic Core
- 01Scrape federal EPA EHS lists monthly
- 02Reconcile logs against threshold planning quantity
- 03Generate 'Compliance Readiness' triggers at 90% threshold
Recommended Tech Stack
Implementation Blueprint
1. Build an automated scraper for the EPA EHS consolidated list (List of Lists).
2. Integrate with internal 'Chemical Inventory' logs to aggregate volumes across multiple facility zones.
3. Implement 'Threshold Proximity Alarms' that notify the EHS Manager before a reporting requirement is triggered.
4. Automate the generation of the Tier II form pre-populated with CAS numbers and hazard classes.
5. Create a 'Audit Shield' vault with time-stamped proof of non-threshold status for previous reporting cycles.
