Substances of Low Interest

EPA has also designated a list of specific chemical substances, by CAS Number, as exempt from certain information requirements under the lUR because that information would be of low interest. In developing this list, EPA considered, among other things, whether the volume at any site exceeded the three-hundred thousand pound threshold where extensive data submission requirements become applicable the substance s physical and chemical properties and potential for persistence, bioaccumulation, health effects, or environmental effects information needs of various constituencies availability of other complementary risk screening information comparable processing and use information and whether the potential risks of the substance are adequately managed.  

Any person who manufactured or imported for commercial purposes a reportable chemical substance in the amount of twenty-five thousand pounds or more at any one owned or controlled site during the calendar year is subject to reporting for that chemical substance. For importers, the site of importation is the site of the operating unit that is directly responsible for importing the substance and controls the import transaction, which can in some instances be the organization s domestic headquarters.  

Excluded from the reporting requirement are small manufacturers or importers. Small means having total annual sales, when combined with its parent company, if any, of less than 40,000,000, except that if a substance is manufactured or imported at any one site in excess of one-hundred thousand pounds, the entity and parent company must have combined sales of under 4,000,000 to be exempt from reporting. However, the exemption does not apply if the substance is subject to a rule proposed or promulgated under TSCA 4, 5(a)(2), 5(b)(4), or 6, or is the subject of an order issued under 

The rules allows EPA to adjust these sales volumes for inflation. 

Any person who submitted the information required by the lUR in compliance with a TSCA 8(a) rule within one year of the start of a reporting period is not again required to report on the manufacture of that substance at that site during that submission period. When two or more importers are involved in a particular import transaction, they may determine among themselves who should submit the required report. However, each such importer will be Hable for failure to report if no report is filed.

The rules provide two categories of chemical substances, petroleum process streams, and chemical substances of low interest, with relief from certain information requirements. Manufacturers and importers of chemicals subject to this partial exemption are required to submit lUR data but are not required to submit industrial processing and use information and commercial and consumer use information otherwise required for manufacturers or importers of products in excess of three-hundred thousand pounds at any one site. Inorganic chemical substances had also benefitted from this partial...
