Part 6: Closure

This part of the checklist/questionnaire is applicable

to all dangerous waste management facilities operating

under interim status. Dangerous waste facilities may

include containers. tanks. surface impoundments. waste

piles. thermal treatment. chemical. physical and

biological treatment. land treatment. incinerators. and

landfills.

The abbreviation "0/0" is used frequently throughout

this checklist/questionnaire and stands for the words

"owner and/or operator."

The questions in the checklist have been written in a

manner such that they can be answered either "Yes" or

"No. " However. the answers to some questions may

require additional explanation. The space provided for

comments at the end of each section may be used for

explanations. If a question does not apply to a

particular facility. simply write "NA" (not applicable)

next to the question.

the ~articular facility under investigation.

Please note that with respect to surface

impoundments, waste piles and land treatment

units. if if % either cannot or elects not
