1998 EPCRA 313 Q&A, Question # 391

391. How are toxic chemical categories handled under Section 313 threshold determinations and release and other waste management calculations?
All toxic chemicals in the category that are manufactured, processed, or otherwise used at a covered facility must be totaled and compared to the appropriate thresholds. A threshold determination for toxic chemical categories is based on the total weight of the compound. Except for metal compound categories and nitrate compounds, the total weight of the compound released or otherwise managed as waste must be reported. Releases and other waste management quantities of metal compounds are reported as the parent metal portion of the compounds. If the metal and corresponding metal compounds exceed thresholds, a joint report for metal compounds, including the parent metal, can cover both reporting requirements. Similarly, releases and other waste management quantities of nitrate compounds are reported as the nitrate portion of the compound.
