SAFETY POLICIES AND PROCEDURES MANUAL
Environmental Health and Safety
Recycling or Disposal of Chemical Wastes
University personnel must manage chemical waste in accordance
with local, state, and federal regulatory requirements. Compliance is necessary
to protect the health and safety of University employees, students, and visitors
and to meet local, state, and federal regulatory requirements.
WSU must comply with federal, state, and local hazardous waste
laws and regulations.
- The U.S. Environmental Protection Agency (USEPA), the Washington State
Department of Ecology (WDOE), and the U.S. Drug Enforcement Agency issue
regulations implementing federal and state laws.
- Local governments regulate discharges to the sanitary sewer systems.
Violations of federal, state, or local law may result in fines
and/or imprisonment for University personnel, supervisors, and administrative
provides procedures for identification and storage of chemical wastes.
Policies and procedures in 5.66 and 5.68
apply only to the management of chemical wastes which are regulated by the
United States Environmental Protection Agency (EPA), the Washington State
Department of Ecology, and the United States Drug Enforcement Agency (DEA).
These procedures do not apply to radioactive wastes. The Radiation
Safety Office manages radioactive substances. Telephone 509-335-8916 for assistance
or refer to 9.70.
These procedures do not apply to biohazardous wastes. Refer to 4.24 regarding options for biohazardous waste treatment and disposal. Contact the WSU Biosafety Officer; telephone 509-335-9553; or Facilities Services—Operations; telephone 509-335-4530 for questions regarding biohazards.
Environmental Health and Safety (EH&S) assists departments by collecting, designating, recycling,
and disposing of hazardous chemical wastes.
EH&S provides departments with information about waste minimization
and with directions for preparing hazardous chemical wastes for recycling

A waste generator is a person who creates chemical wastes.
The waste generator is responsible for determining whether chemical
wastes meet federal, state, and/or local government definitions of dangerous
Identify which wastes must be managed as dangerous waste (see above).
Wastes defined as dangerous wastes must be packaged, accumulated, transported,
and disposed of in a safe and legal manner.
Examples of dangerous wastes include laboratory chemicals, photographic
processing chemicals, leftover paint, automobile fluids, and other maintenance
As an alternative, report all wastes by submitting a Chemical
Collection Request to Environmental Health and Safety (EH&S). See Reporting Wastes below. EH&S determines the proper management method.
WSU Spokane, WSU Tri-Cities, and WSU Vancouver Departments
For identification and management guidance, WSU Spokane, WSU Tri-Cities, and WSU Vancouver departments use the applicable campus chemical collection or chemical reporting form to report wastes to the campus EH&S office. See Reporting Wastes below.
Aerosol Containers, Batteries, and Light Bulbs
Pressurized aerosol containers (even when empty), all batteries, and all light bulbs are considered
to be regulated hazardous waste and must not be disposed of in trash
cans, dumpsters, or any other uncontrolled waste receptacle.
EH&S provides labeled containers for pressurized containers, batteries, and light bulbs
in waste accumulation areas at various campus locations. Contact the applicable EH&S support personnel
for the locations of the waste accumulation areas or to arrange waste pickup.
Electronic waste, including monitors, televisions, CPUs, printers, and keyboards, is regulated waste and must not be disposed of in trash cans, dumpsters, or any other uncontrolled waste receptacle.
Departments are to dispose of electronic waste by submitting an online Surplus Disposal Request (SDR) to Facilities Services—Surplus Stores. (See BPPM 20.76.) Surplus Stores collects unwanted electronics upon receipt of the SDR.
Chemicals identified by the Drug Enforcement Administration (DEA) as controlled substances must be handled in accordance with the requirements of BPPM 45.75.
Each department is responsible for properly labeling, preparing,
and safely accumulating all chemical wastes generated. Refer to 5.68
for chemical waste storage procedures.
Each generator is responsible for minimizing chemical waste
generation through prudent purchasing practices, product substitution, recycling,
or reducing the amount of chemicals used by the department.
Providing Hazard Data
To facilitate safe and legal management of hazardous materials,
each department is responsible for providing hazard information (i.e., a
Safety Data Sheet) to EH&S upon request. See also 5.10.
The waste generator is responsible for properly collecting chemical
wastes in the following manner:
- Place each chemical waste in a separate, leak-proof container which
does not react with the substance. Usually this is the original container. The generator is responsible for supplying the waste containers.
- Securely attach a proper lid on each container when not adding waste.
- Do not combine different waste streams in the same container without permission from EH&S.
Segregate containers of potentially reactive chemicals (e.g.
acids/bases or oxidizers/flammables) in order to prevent reactions prior
to or during accumulation or collection. See 5.68 for chemical waste storage procedures.
- Provide secondary containment, e.g., a plastic tub, for any primary
container that may leak or rupture. See 5.62 for chemical spill
The waste generator is responsible for properly labeling chemical
Place a dangerous waste label on each container when waste is first added.
See example in the PDF version of 5.66.4.
Obtain a dangerous waste label using one of the following methods:
- Print a Dangerous Waste Label from the EH&S website:
- Order a Dangerous Waste Label EH&S; telephone 509-335-3041.
- Print a Dangerous Waste Label for use by waste generators at WSU Spokane from the Hazardous Waste area of the WSU Spokane EH&S website at:
- Print a Dangerous Waste Label for use by waste generators at WSU Tri-Cities from the WSU Tri-Cities EH&S Hazardous Waste Accumulation, Storage, and Labeling webpage at:
- Obtain a Dangerous Waste Label for use by waste generators at WSU Vancouver from the campus EH&S Coordinator.
- Obtain a Dangerous Waste Label for use by waste generators at research and extension centers (RECs) from the REC EH&S Coordinator.
- Create a label. See below for information required on the label.
Each self-created label must contain all of the following information:
- Name of each constituent. Do not use chemical formulae or abbreviations.
- Percentages/amounts of each constituent. Account for 100% of the waste constituents on the container
label, including water.
- Hazards the waste presents (e.g., flammable, corrosive, toxic).
- The words "DANGEROUS WASTE."
- Chemical Collection Request (CCR) number. See the PDF version of 5.66.6.
University personnel who generate surplus hazardous chemicals or chemical waste
are responsible for reporting those chemicals to EH&S for subsequent
recycling or disposal.
Chemical Collection Request
Use a Chemical Collection Request (CCR) form to report chemicals
for disposal or recycling. The CCR form may be obtained using one of the following methods:
After completing the CCR, enter the CCR number onto the Dangerous Waste label attached to the waste container. (See the PDF version of 5.6.4-5).
After receiving the completed Chemical Collection Request form, EH&S personnel determine
the appropriate management method and assign all applicable waste designation
EH&S collects the chemicals and coordinates and contracts for transportation,
recycling, or disposal of waste chemicals.
NOTE: EH&S's response to departmental requests for disposal of certain
chemicals may be delayed until a disposal facility is found to accept the
EH&S reviews all wastes for recycling alternatives.
INAPPROPRIATE DISPOSAL METHODS
EH&S maintains a stock of unused chemicals at the Pullman campus only, which are available
for recycling to University personnel. The list of chemicals appears on the EH&S website:
To request free delivery of a chemical on the recycling database, WSU Pullman departments e-mail
EH&S from the website or call 509-335-3041.
To recycle surplus chemicals from a lab or work area, submit the chemicals
to EH&S using the waste reporting procedure described above. EH&S
determines whether the chemicals are acceptable for recycling.
Drains, Trash, Evaporation
Disposal of dangerous chemical wastes in drains, by evaporation,
or by placement in the regular trash system is a serious violation of local,
state, and federal law, punishable by fines and imprisonment.
When a generator of dangerous wastes illegally or inappropriately dumps
such waste in the trash contaminating common refuse (trash, paper, etc.),
the entire mixture may become a "dangerous waste." This practice
may result in costly disposal.
The University may require generators who create such disposal problems
to pay for disposal.
DO NOT DISPOSE OF CHEMICALS IN DRAINS, TRASH, OR BY EVAPORATION WITHOUT
PRIOR EH&S APPROVAL.
A hazardous chemical waste cannot be rendered nonhazardous by
dilution with water or solvent.
Under unusual circumstances, and with prior EH&S approval, disposal
by one of the above methods may be legal and appropriate. Contact EH&S
for more information; telephone 509-335-3041.
If a chemical spill occurs in a laboratory, refer to:
- The WSU Laboratory Safety Manual,
- The lab's spill response and emergency plan, and
- 5.62 for chemical
spill management procedures.
Refer to 5.62
for chemical spill management procedures.
Call 911 if involved personnel are uncertain about the nature
of the spill or require assistance with spill management procedures.
