The Preliminary Assessment Information Rule—PAIR

Under PAIR, manufacturers and importers of fisted chemical substances are required to report a standard set of data to the EPA. The data set includes items such as the quantities manufactured or imported, whether the chemical is used on site or distributed, how much is released to the environment, and purposes to which customers put the chemical. The required data is fisted on the PAIR Form, and use of the EPA s form is mandatory.  

The information to be included on the form is intended to gather very preliminary exposure data to permit the Agency to assess testing priorities.i When promulgated in 1980, PAIR was intended by EPA to be the first of a series of progressively more detailed reporting rules under TSCA 8(a) to establish a comprehensive assessment of chemical substances.  

A separate PAIR form must be completed for each chemical and each site where a fisted chemical substance or mixture is manufactured or imported in quantities of five hundred kilograms (eleven hundred pounds) or more, unless an exemption applies.  

The PAIR form is EPA Form No. 7710-35, Manufacturers Report Preliminary Assessment Information, available at http //www.epa.gov/oppt/chemtest/pubs/ pairform.pdf. 

See 45 Fed. Reg. 26992 (June 22, 1982). As stated by the Agency, the information collected under this rule will answer a critical need for basic data that can be used in setting priorities for testing chemicals and for assessing risks associated with chemicals. Id.
