Data collection and inventory accuracy
Are you tracking chemicals year-round or scrambling when they’re audited?
Tier II reports on your highest on-site quantities across the full calendar year. If you're not tracking continuously, you're not reporting accurately.
If you checked fewer than 3: Your Tier II data has gaps before filing season begins.
What accurate inventory tracking looks like
Continuous, container-level visibility isn't a manual process, it's an infrastructure decision. When chemicals are tracked via RFID at the container level, maximum on-site quantities are recorded as they occur, not reconstructed after the fact. Every movement, transfer and disposal updates the inventory in real time, so when March arrives, the data is already there. The question stops being "what do we think we had?" and becomes "here's exactly what we had and here's the record to prove it."
