182. How would a compound that falls into two reporting categories be reported (e.g., PbCrO3) on the Form R?
A compound that has constituents in two listed categories would have to be included under both categories when submitting a Form R. In the example indicated, the total weight of PbCrO3 must be included in determining the threshold for both lead compounds and in determining the threshold for chromium compounds. In reporting the releases and other waste management of lead, only the stoichiometric weight of the lead in PbCrO3 released or otherwise managed as waste would be included. Likewise, only the chromium in PbCrO3 that is released and otherwise managed as a waste would be included on the Form R.
