EPA Tier II Router
5 of 14 chemicals at 2 facilities meet EPCRA 311/312 thresholds (3 extremely hazardous, 2 hazardous) and go on the 2025 Tier II report. 3 data issues to fix before filing.
250 gal x 15.3 lb/gal = 3,825 lbs (Anodizing tank room), 2,400 lbs x 35% = 840 lbs (Maintenance shop), 10 gal x 15.3 lb/gal = 153 lbs (QC laboratory). 3,825 + 840 + 153 = 4,818 lbs on site, at or above the 500-lb threshold (EHS: lesser of 500 lbs or the TPQ of 1,000 lbs; 40 CFR 370.10(a)). The QC laboratory line's CAS 7664-93-8 fails the check digit, so it was matched by name.
Method1EHS list: Built-in reference subset of 40 CFR Part 355 Appendix A (15 substances). The built-in list is a labeled subset, not the full Appendix A; upload the full list to replace it. Two-number TPQs for solids use the lower number.
2Thresholds (40 CFR 370.10(a)): an EHS is reportable at 500 lbs or its TPQ, whichever is lower; other hazardous chemicals at 10,000 lbs; a chemical is reportable at or above its threshold.
