• Title: Extremely hazardous substances (EHSs); Reportable Quantity Adjustments


The EPA is proposing to adjust reportable quantities (RQs) for 232
extremely hazardous substances proposed for designation as hazardous
substances under the Comprehensive Environmental Response,
Compensation, and Liability Act (CERCLA) of 1980. These substances
were originally listed as EHSs pursuant to section 302 of the
Superfund Amendments and Reauthorization Act (SARA) of 1986 and were
subsequently proposed for designation on January 23, 1989 (54 FR
3388). By adjusting the one- pound reporting triggers proposed under
CERCLA section 102 and currently in effect under SARA section 304,
EPA will reduce the reporting and response burdens on the regulated
community and on Federal, State, and local governments respectively.
EPA also is proposing to adjust the RQs of 19 EHSs that are already
listed as CERCLA hazardous substances but have RQs greater than
their threshold planning quantities (TPQs). To adjust the RQs of
these 251 substances, EPA is proposing to apply the methodology used
to establish TPQs as part of the RQ adjustment methodology for those
CERCLA hazardous substances meeting the EHS screening criteria.
Comments must be submitted on or before October 30, 1989.
