Resource Conservationand Recovery Act (RCRA) “Cradle to grave” management of hazardous wastes
Hazardous and SolidWaste 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 – Specificand 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. http://www.epa.gov/osw/hazard/wastetypes/pdfs/listing-ref.pdf
Characteristic Wastes • Ignitable (D001 Waste Code) • Flash point <140oF • Corrosive (D002 Waste Code) • pH < 2 or > 12.5 • Reactive (D003 Waste Code) • Unstable • Air/water reactive • Toxic (D004-D043 Waste Codes) • Heavy metals • Certain pesticides
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 on-campus • 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
Identification • Who • What • When • Where • Quantity
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
Substitution • Hexachlorocyclohexane, gamma- • Hexachloroethane • Methoxychlor • Naphthalene • Pendimethalin • Pentachlorobenzene • Pentachloronitrobenzene • Pentachlorophenol • Phenanthrene • Polycyclic Aromatic Compounts (PAC’s) • Pyrene • Trifluralin • Cadmium • Lead • Mercury • 1,2,4-Trichlorobenzene • 1,2,4,5-Tetrachlorobenzene • 2,4,5-Trichlorophenol • 4-Bromophenyl phenyl ether • Acenaphthene • Acenaphthylene • Anthracene • Benzo(g,h,i)perylene • Dibenzofuran • Dioxins/Furans • Endosulfan • Fluorene • Heptachlor • Hexachlorobenzene • Hexachlorobutadiene
OrphanChemical Program • reduce disposal costs • reduces purchasing costs for new materials
