Waste Policies and Procedures Manual - 2003 Edition
This manual was prepared
for use within ISU. It is intended for use by, and applies to, ISU
employees, staff, visitors, and students. If this manual or any portion
of it is used elsewhere, neither its authors nor the University accept
responsibility for its contents.
5.0 SPECIFIC HAZARDOUS
Any material which is to be discarded, abandoned, or accumulated prior
to recycling is considered a waste. Some major categories of hazardous
materials and potentially hazardous wastes are provided below, including
examples. If you are uncertain about a particular waste, please contact
TSO at x2310.
Because it is impossible to provide a complete classification of all possible
hazardous waste in this manual, please contact the TSO at x2310 before
discarding any chemical or other potentially hazardous waste that you generate.
Waste is not to be transported anywhere or placed in front of the Temporary
Accumulation Area (bldg. 16 B) by anyone that is not TSO staff. Waste
will not be transported by TSO staff unless it is in a container that complies
with all regulations. A discussion of proper containers can be found
in Section 6.3.1 of this manual.
Perhaps the most expensive and time-consuming group of potentially hazardous
waste is the unknown. If no identity can be assigned to a material,
or it cannot be determined by process knowledge, the unknown must be subjected
to analytical procedures that can cost ISU many hundreds of dollars and
take several weeks to complete. The cost for these analyses is generally
borne by the TSO, unless abuse of this service is detected. Most
unknowns can be avoided by using standard laboratory protocol:
should NOT be placed in an SAA or transported by TSO staff to the TAA until
an analysis of the unknown has been completed. Exposure of certain
material to weather extremes can create dangers of fire, explosion, or
container rupture and subsequent expensive cleanup activities and potential
for environmental contamination.
label each container as to its
contents, date received or prepared, and concentration.
obtain MSDSs from the manufacture
and have them on hand. For newly purchased materials the ISU purchasing
department will route MSDSs provided by the manufacturer to the department
that bought the materials.
5.2 Abandoned Material
Material that has been abandoned, or for which ownership cannot be identified,
may be hazardous waste. If the identity of the material is not known,
it is treated as an unknown (Section 5.1). If the identity of the
abandoned material is known, notify the TSO at x2310 for characterization
and pick-up. Abandoned material that is deemed hazardous must be
stored properly upon discovery.
Material with questionable purity cannot be expected to be used in either
a teaching or research capacity. While some of these materials may
be hazardous waste once they are characterized, others often are not, but
still must be disposed of properly. The TSO will assist individuals
with this task to ensure safe and environmentally sound disposal practices.
5.4 Expiration Date
Some materials have specified expiration dates which must be observed for
a variety of valid reasons, which include purity, safety, and regulatory
concerns. For example, peroxide forming chemicals, some of which
are listed in Appendix G, have expiration dates which should not be exceeded
under any circumstances. In addition, manufacturers often supply
expiration dates on labels of materials that are related to potency or
even composition changes that occur with time, temperature, or other storage
conditions. These dates should always be observed, and if they are
exceeded, the material is to be considered a waste and characterized to
see if it meets hazardous characteristics.
5.5 Materials from
Discontinued or Completed Activities
When these materials are no longer useful, they may be considered hazardous
waste. However, another possibility is to recycle them by identification
through the ChemSwap program or department transfer. Each Department
Material Manager or laboratory supervisor should attempt to determine whether
a material they need is available elsewhere on campus before buying more
from an outside vendor. This will help reduce the financial burden
on both initial cost and ultimate disposal cost when it is eventually declared
as a hazardous waste. Some examples of these kinds of activities
It is very important to clean chemicals out of a laboratory BEFORE a principal
investigator or researcher leaves the University. Unknown or questionable
chemicals left in laboratories are very expensive to test. Please
consult with TSO personnel concerning the fate of these materials and the
procedures to be followed to ensure proper closure of a laboratory or program
within a lab.
A principal investigator or
researcher leaves the University.
Lab work on specific projects
The responsibility for a lab
or work area changes.
5.6 Excess Stock
Excess stock with no likelihood of use either by their current owners,
the department, or others elsewhere on campus, is considered waste.
Careful planning when purchasing materials can reduce the volume of excess
material that must ultimately be managed as hazardous waste. Some
helpful ways to accomplish this goal are presented in Section 9, entitled
"Hazardous Waste Minimization Programs".
5.7 Spent Cleaning
and Wash Solvents
Spent cleaning and wash solvents are almost always considered hazardous
waste, because either the solvent itself or the materials which contaminate
the solvent are considered hazardous. There are options as to the
types of solvents and processes used which may not be regulated as hazardous
waste. Currently, spent solvents from automobile, diesel, aircraft,
or other parts washers at ISU are recycled under a monitored program. Other
generators of spent solvents should contact the TSO for waste solvent management
options. Rags used in these processes also become a hazardous waste
when using a hazardous solvent. These rags must be stored in a closed
and labeled container in a SAA. Laundering of these rags may not
be an acceptable alternative. TSO can help identify whether or not
these rags can be laundered for reuse.
5.8 Waste Paints
Waste paints and stains which contain hazardous metals in the specific
D-list on Appendix D or hazardous solvents which may be flammable, must
be considered hazardous waste. Old paint cans meeting these characteristics
which have hardened contents must also be presented for proper disposal.
Most water-based latex paints currently are not considered to be hazardous,
but may not be acceptable to a municipal solid waste landfill. Currently,
TSO solidifies latex paint before arranging for disposal at the landfill.
Spray paints may also meet the hazardous criteria. Please consult the TSO
for proper disposal information.
5.9 Motor Oil and
Regulation on used motor oil and filters are subject to change. Currently,
oil is recycled, but properly drained filters are disposed of as ordinary
trash. The State of Idaho regulates these items. If you have
questions concerning either the regulatory status or recycling options,
contact the TSO. Oil must be recycled through a recycler that has
obtained an EPA identification number. All oil must be drained from
filters before the filter can be recycled or disposed of. Proper
drainage procedures consist of punching a hole in the filter and letting
it drain for 24 hours. All containers used to store used oil for
any length of time must be marked with the words “USED OIL”.
5.10 Mercury and
Metallic mercury is commonly found in instrumentation such as thermostats,
thermometers, and barometric pressure equipment. Bulk quantities
of metallic mercury or mercury sulphide can usually be recycled.
However, articles contaminated with mercury or its compounds must be disposed
of as hazardous waste. The TSO has collection containers for the
recycling of mercury and mercury sulphide compounds.
Cleanup of a mercury spill from a broken thermometer generates large quantities
of mercury-contaminated waste that is very costly to dispose of.
For the University, it is far less expensive to obtain an electronic or
environmentally friendly thermometer than to pay disposal costs of a broken
mercury thermometer. The TSO recommends that you do not buy new mercury-containing
equipment for use at ISU when good alternatives are available.
Mercury compounds are currently very expensive to dispose of and many are
P-listed wastes. Every attempt to find alternatives to using mercury
compounds should be made. The cost per gram of disposal is approximately
50 to 200 times the purchase cost. If you have mercury compounds
to dispose of, consider sulphide precipitation as a final step in your
process. Currently, mercury sulphide is the only mercury compound
which is accepted for recycling.
Older electrical transformers often contain PCB dielectric oils.
In the past, great expense has been incurred in testing for and disposing
of these fluids from equipment that has been donated to the University.
DO NOT ACCEPT DONATED ELECTRICAL EQUIPMENT UNTIL IT HAS BEEN EVALUATED
BY TSO PERSONNEL FOR HAZARDOUS MATERIALS! The cost to dispose of
contaminated donated equipment is very high and can be avoided if equipment
is properly evaluated prior to acceptance.
The Technical Safety Office currently receives all waste light ballasts
collected by various Maintenance and Operations (M&O) personnel.
Once collected, these ballasts are characterized by the Technical Safety
Office as to whether they contain PCBs. This characterization is
determined by the specific manufacturer and date of manufacture.
Under the Toxic Substance Control Act, the manufacturing of ballasts containing
PCBs after 1979 is prohibited.
Today manufacturers of fluorescent light ballasts cannot legally produce
PCB containing ballasts under TSCA. Ballasts which do not have PCB
material can be recognized by the following:
5.13 Donated or "Free"
have the label "NO PCBS"
have a manufacturing date which
is later than 1979 or
are General Electric with a
serial number starting with "8G" or ending in "W".
ISU has spent thousands of dollars on hazardous waste disposal of "free"
hazardous material donated to the University. Do not accept any donated
hazardous material from any outside source without first consulting with
Spent or unwanted batteries may be classified as hazardous waste, mainly
due to their toxicity characteristics (RCRA D-listed waste). Batteries
are subject to the toxicity characteristic leachate procedure (TCLP) to
determine whether or not they are hazardous waste. Because these
batteries are manufactured within specified tolerances, a representative
sample may be used for a waste characterization for a given brand and type
Batteries highlighted in Appendix T have been determined to be a hazardous
waste when spent or unwanted, and are subject to the hazardous waste guidelines
in Section 6 of this manual.
Spent lead-acid batteries, such as motor vehicle batteries are not subject
to federal hazardous waste regulations provided that they are reclaimed
as described in 40 CFR 266.80. Contact TSO for the names of local
lead-acid battery recyclers. Non-hazardous waste batteries
do not need to be accumulated in a SAA nor are they subject to storage
time constraints associated with hazardous waste. However, batteries
should be stored in a secondary container, such a polyethylene tub to prevent
contamination to the environment and should not be accumulated. Contact
the TSO for transportation of these batteries to a recycling facility.
Batteries that are hazardous waste should have a label attached with the
words “USED BATTERY” in the chemical description. Call TSO to pick
up the hazardous waste battery if it cannot be placed in a SAA. If
the battery is leaking, it must be placed in a sealed container.
and Radiographic Solutions
Spent material used in developing X-ray films and photographic negatives
and prints contain silver compounds from dissolution of the emulsion on
print paper. These silver compounds are regulated under both RCRA
and the City of Pocatello NPDES pre-treatment standards, and must be recycled.
For large generators, silver may be removed from waste streams at the point
of generation and recycled. For smaller generators, the liquid
wastes may be transported off site for recycling. Solutions containing
spent silver that can be recycled should be labeled with the words “Used
Fixer”. Please contact TSO personnel for details.
Some photographic developing solutions may contain organic compounds that
meet hazardous criteria. These solutions must be disposed of as hazardous
waste and may not be able to be recycled.
Some electrical lamps contain hazardous materials, such as mercury, and
require proper management when no longer needed.
5.16.1 Sodium Vapor
Sodium vapor lamps contain metallic sodium, which represents a fire and
explosion hazard when exposed to either moist air or water. These
lamps should not be disposed of as normal trash, and must not be broken.
Please take them to the Heat Plant, where barrel storage is located.
Contact TSO personnel for assistance.
5.16.2 Mercury Vapor
Mercury vapor lamps contain small quantities of metallic mercury and/or
mercury compounds that are considered hazardous waste under RCRA.
These items must be collected for proper disposal. Contact the TSO
personnel for collection and transportation of these vapor lamps.
Fluorescent light tubes contain a small amount of mercury that requires
them to be tested by the toxicity characteristic leachate procedure (TCLP)
for hazardous waste determination. There is insignificant data yet
as to whether or not fluorescent light tubes in general pass or fail the
TCLP. However, fluorescent light tubes that fail the TCLP must be currently
managed as a hazardous waste. The GE fluorescent light tubes purchased
under contract by ISU have been tested and found to pass the TCLP.
Accordingly they are managed as ordinary trash. In order to prevent
breakage during handling, it is recommended that spent fluorescent light
tubes be placed in original packaging material prior to disposal.
5.17 Contaminated Materials
Materials contaminated with a hazardous waste may also become a hazardous
waste. Spill cleanup material, PPE, laboratory bench coverings, chemical
storage cabinets, glassware, rags, etc., must all be evaluated before disposal
into ordinary trash. Construction materials are often overlooked
as being a hazardous waste. Any ductwork from fume hoods should be
evaluated for hazardous materials before disposal.
