355.16 How do I determine the quantity of extremely hazardous substances present for certain forms of solids?

For the three forms of solids that are listed in §355.15(a)(1) through (3) , use these instructions to determine the quantity of extremely hazardous substance present:

(a) Solid in powdered form with a particle size less than 100 microns . Multiply the weight percent of solid with a particle size less than 100 microns in a particular container by the total weight of solid in the container.

(b) Solid in solution . Multiply the weight percent of the non-reactive solid in solution in a particular container by the total weight of solution in that container. Then multiply by 0.2.

Note to paragraph (b): This reduction in quantity must not be used to determine the amount present at one-time at a facility for reporting under 40 CFR 370.10 .

(c) Solid in molten form . Multiply the weight of the non-reactive solid in molten form by 0.3.

Note to paragraph (c): This reduction in quantity must not be used to determine the amount present at one-time at a facility for reporting under 40 CFR 370.10 .
