definitions as are found in subsection WAC 173-303-040 of the Dangerous Waste
Conditionally Exempt Recycling Facility
Conditionally exempt recyclers are companies that are allowed to receive and
recycle hazardous waste without acquiring a hazardous waste TSD facility permit.
These recyclers are expected to follow all the requirements of a large quantity
generator. For example contingency plans, training plans, and record retention
are required. Conditionally exempt recyclers are also required to begin the
recycling process within 72 hours of receiving the hazardous waste, and
therefore are not allowed long-term storage. The 72-hour limit is Ecology’s
outside time limit for beginning the recycling process. Conditionally exempt recyclers are
required to sign off as the receiving facility on manifested hazardous waste
shipments as soon as it arrives within the boundary of the facility.
Conditionally Exempt Small Quantity Generator
If the quantity of dangerous waste generated per month does not equal or exceed
the quantity exclusion limit for that waste, a generator may qualify for
conditional exemption from most of the regulatory requirements. For most wastes
the quantity exclusion limit is 220 pounds. If a generator has an acute
hazardous waste the quantity exclusion limit is 2.2 pounds. Other conditions for
exemption include limiting accumulation on-site of dangerous waste to under
2,200 pounds (2.2 pounds for acute hazardous waste), safe management, proper
disposal to a dangerous waste facility allowed to take dangerous waste, or
proper treatment and discharge to a publicly owned treatment works facility
under a discharge permit.
Cradle to Grave
The cradle to grave system is the concept of accounting for hazardous waste from
the point of generation until it is no longer hazardous (for example, treatment), it is
destroyed, (for example, incineration), or it is disposed of (for example, placed in a
landfill). The federal Resource, Conservation, and Recovery Act (RCRA) and
Washington’s Dangerous Waste Regulations (Chapter 173-303 WAC) are based on this
The process of waste designation is the responsibility of the generator.
Designation is the identification of the hazards and risks posed by a solid
waste. (Solid waste is a regulatory term that can mean waste with a variety of
physical states, from liquid to semi-solid (sludge) to solids.)
Financial requirements placed on dangerous waste facilities to provide
for closure costs and liabilities from waste management activities. Financial
assurance can include trust funds, surety bonds, letters of credit, insurance,
or financial test and corporate guarantees.
Large quantity generator
Generators of dangerous waste that produce greater than 2,200 pounds per
calendar month, or greater than 2.2 pounds of acutely hazardous wastes.
Medium quantity generator
Generators of dangerous waste that produce greater than 220 pounds per calendar
month but less than 2,200 pounds per calendar month, and do not accumulate more
than the upper limit on-site.
Generators are allowed to recycle their dangerous waste at the site of
generation as long as it is properly managed and quantities are appropriately
counted toward generator status and annual reporting.
A Significant Non-complier (SNC) according to Ecology’s enforcement policy is a
violator that 1) has caused actual exposure, or a substantial likelihood of
exposure, of hazardous waste or hazardous constituents to humans or the
environment, 2) is a chronic or recalcitrant violator, or 3) substantially
deviates from the conditions of a permit, order, agreement, or hazardous waste
statutory or regulatory requirement. EPA sometimes refers to SNC status as
“High-Priority Violator” or HPV.
Secondary violators are those facilities with violations that do not meet the
criteria listed for significant non-compliers. Secondary violators pose no
actual threat, or a low potential threat, of human or environmental exposure to
hazardous waste or constituents. A facility classified as a secondary violator
should not have a history of recalcitrant or non-compliant conduct.
Ecology considers violations that threaten, or have potential to threaten human
health or the environment to be “high priority” and serious. Some examples of
serious violations include unreported spills, drums or containers without secure
lids, and mistakes about waste identification.
State/EPA ID number
A State EPA ID number in Washington is geographically assigned, and begins with
the letters “WA” followed by another letter or number, and a string of 9
Treatment, Storage, and/or Disposal Facility (TSDF)
A dangerous waste management facility permitted under the Resource Conservation
and Recovery Act (RCRA) or Washington’s Dangerous Waste Regulations. Examples of
dangerous waste management includes recycling, rendering non-hazardous or
less-hazardous through treatment, storage, hazardous waste fuel blending,
incineration, and land disposal.
Used Oil Processor
Used oil processors accept and manage a variety of petroleum-based materials
that can be treated and recycled into fuels or lubricating stocks. The
processing typically involves phase filtering, separation through settling
(phase separation), or heat. Processing may also involve the mixing of acids or
bases and flocculants, or the use of a centrifuge to further separate oils from
water or other contaminants. Used oil processing may be found as a stand alone
operation, or as part of other waste management activities at a multi-purpose
Used oil processors are facilities that receive used oil and oily wastes to
recycle, refine, and/or recover oil under WAC 173-303-515 and 40 CFR Part 279,
subpart F. These regulations allow used oil that would otherwise be considered a
hazardous waste to be managed under less stringent standards.
