Question 39: Can biological material be defined better in

20.2003? For example, is all organic material biological

material? Can animal fats be released to the sewer?



Answer: Biological material, in its ordinary meaning, is

material pertaining to living organisms (plants or

animals). The statement of considerations indicates that

ground-up animal carcasses are examples of such material.

Animal fats are biological material and, if "dispersible,"

can be released to the sewer. (Reference: 10 CFR 20.2003

(a) (1))
