EPA regulatory flags
EPA marks this listing with 2 flags. Each one is shown with EPA's own definition and what it obliges.
Indicates a commenced PMN substance.
What it obliges: Nothing new. The substance already went through premanufacture review and someone filed a notice of commencement, which is why it is on the Inventory. It is an existing chemical and needs no new premanufacture notice.
What it does not establish: The flag records how the substance arrived, not what may be done with it. Check the flags beside it.
Indicates a substance exempt from reporting under the Chemical Data Reporting Rule, (40 CFR 711).
What it obliges: Nothing, for this substance, in the CDR census. The exemption belongs to the chemical and not to your company, so every other substance you make above the reporting threshold still counts.
What it does not establish: Says nothing about hazard, about commercial activity status, or about obligations under any other part of TSCA.
