$1$: Determine, using the procedures outlined by RCRA, if each of the following is a hazardous waste.

State the reason why it is or is not a hazardous waste according to the RCRA definitions. If it is a

hazardous waste, list the RCRA waste category number. Assume that the industry producing the

waste is a RCRA hazardous waste generator. Please refer to the Appendix section in your book or

the PDF included below.

a$.$ A drum containing a solution of NaOH at $pH13.$

b$.$ A drum of off$-$specification ethyl acetate that is to be disposed of$.$

c$.$ Cement kiln waste.

d$.$ Sawdust in a warehouse contaminated by a spill of acrolein.

e$.$ Distillation bottoms from production of nitrobenzene by nitration of benzene.

f$.$ Spent cyanide plating bath solutions from electroplating operations.

g$.1000Kg$ of commercial pesticide endrin $($pure$)$ that are to be discarded because the company that

purchased this chemical originally does not need it anymore.

h$.$ An aqueous industrial waste stream from a plastic manufacturing plant that is discharged to a river.

i$.$ A drum of waste $20\%$ TCE.

j$.$ Wastewater treatment sludge from the production of zinc yellow pigments.

k$.$ Sawdust contaminated by a $125-kg$ spill of commercially available methyl parathion $($a pesticide$).$

Wastewater discharged by a household to the sewer, the owner of this house has just discharged $0\mathrm{.}5$

L of highly toxic PCE down the drain.

m$.2800k\frac{g}{m}$onth of acetone waste generated as the result of metal parts washing.

n$.235kg$ of heptachlor $($a pesticide$)$ that is being disposed of because it is off$-$specification and out$-$of$-$

date.
