Hazardous and Solid
Waste Amendments (HSWA)
Established three categories of generators
• Large quantity generators (LQGs)
(Generate 2,200 or more pounds of hazardous waste in a
calendar month)
• Small quantity generators (SQGs)
(Generate more than 220 pounds but less than 2,200
pounds of hazardous waste in a calendar month)
• Conditionally exempt generators (CEGs)
(Generate no more than 220 pounds of hazardous waste in
a calendar month)
Hazardous
Waste Defined
Listed Wastes – Specific
and Nonspecific Sources
“F” listed wastes
“K” listed wastes
“P” listed wastes
“U” listed wastes
“F” Listed Wastes
• Non-specific sources
• Wastes from common manufacturing and
industrial processes
– Example: solvents that have been used in
cleaning or degreasing operations.
• Wastes included on the F-list can be found
in the regulations at 40 CFR §261.31
“K” Listed Wastes
• This list includes certain wastes from
specific industries, such as petroleum
refining or pesticide manufacturing.
– Certain sludges and wastewaters from
treatment and production processes in these
industries are examples of source-specific
wastes.
“P” & “U” Listed Wastes
• Must be an unused commercial chemical
product.
• The difference between the “P” and “U”
lists lies in the toxicity of the product. The
acutely toxic products are on the P-list and
less toxic products are on the U-list.

Hazardous Waste Management
Plan for BGSU
• Divided into two phases.
– Phase I: considered as the operational segment and
will involve the identification, collection, storage,
and final disposal of hazardous wastes which are
generated.
– Phase II: In addressing the overall picture of a
hazardous waste management program, a main
emphasis must be placed on waste minimization.
Phase I
• Determine the quantities of
hazardous wastes currently oncampus
• Departments that are identified as
waste generators will be requested
to select a departmental liaison.
Phase II
• Emphasis must be placed on
waste minimization.
–Recycling
–Alteration in Experimentation
–Neutralization

Disposal
• Disposal is performed by BGSU’s
hazardous waste disposal contractor
– Options
• EPA approved landfill
• deep well injection
• incineration
• other thermal destruction
• chemical treatment
Waste Minimization Program
1.) Substitution
2.) Micro-quantities
3.) Drain disposal
4.) Recycling
5.) Neutralization
