Tier 2 Chemical List . Following the alphabetical list, the epcra section 313 chemicals are. Of these chemicals, the aspects that should be listed in a tier ii report are listed below: CUSTOM HAULERS CALL (800) 2146905.coast to coast ,,the family handyman from www.cowboycadillac.com The formulated product has a danger signal word on the label because of high acute toxicity, is listed by us epa as a restricted use product (rup), and/or is highly toxic to fish or other aquatic life, birds, wildlife, or honey bees. The purpose of this form is to provide state, local officials, and the public with specific information on potential hazards. Chemicals reportable under the epcra section 312 tier ii requirements include any substance for which a facility must maintain a material safety data sheet (msds) or safety data sheet (sds) under the osha hazard communication standard (29 cfr 1910).
