What is the difference between hazardous materials, contamination, problem waste and hazardous/dangerous waste?
Being confused about the terminology is understandable. The term “hazardous materials” is a blanket term to include everything from contained substances, contaminated soil, underground storage tanks, dangerous waste and more. As a construction agency, we simplify the terminology to apply the term (and the regulation) as it relates to waste disposal or reuse. For example,
Contamination (also called problem waste) is media (soil, sediment or water) that has some level of toxic substances not normally found in the environment. Disposal or reuse requirements are dependent on site specifics, but generally contamination above Ecology’s MTCA Cleanup Levels (WAC 173-340) requires special handling and disposal.
Hazardous/Dangerous waste (WAC 173-303) would typically be more harmful that “contamination” and also requires special handling, a RCRA Site ID#, a lot more paperwork and can only be disposed at a RCRA permitted Subtitle C facility. The closest Subtitle D facility is in Arlington, Oregon. Transportation projects typically only generate Dangerous Waste on bridge projects with lead based paint. Otherwise projects with contamination will usually be required to sample media (e.g., TCLP test) to prove it is not a “Dangerous Waste” before a permitted landfill or recycling facility will accept the waste.
This is an over simplified casual description of the terms as they typically apply to transportation projects. Formal definitions, corresponding regulations and a nifty graphic for hazardous material terminology is provided in Chapter 447 of the Environmental Procedures Manual (EPM). Formal guidance for managing hazardous materials during construction is provided in Chapter 620 of the EPM.

What happens if there is a spill on a construction site?
All WSDOT construction projects have a Spill Prevention, Control, and Countermeasures (SPCC) Plan as per Standard Specification 1-07.15(1), which is developed by the contractor and approved by WSDOT prior to the start of construction. In the event of a spill, the contractor follows the spill response and notification procedures outlined in the SPCC Plan. Depending on the situation, the WSDOT Project Engineer may initiate the Environmental Compliance Assurance Procedure (ECAP) which is outlined in Section 1-2.2K(1) of the Construction Manual M41-01. Additional information is available on the WSDOT Spill Prevention web page.

What happens if there is a spill from the traveling public?
The cleanup of spills by the traveling public is regulated under CERCLA Section 9607(b). The Washington State Patrol (WSP) and Ecology must be immediately notified.
If the spill from the traveling public occurs within a WSDOT construction project, WSDOT personnel are responsible to immediately notify WSP and Ecology to report the spill and if possible, identify the responsible party. If the spill is an immediate threat to human health or the environment (e.g., tank truck leaking into a water body), WSDOT personnel should take action to contain the spill until Ecology or the WSP arrive on the scene. Cleanup costs may be recovered at a later date if and when the responsible party is identified.

Who do I contact for questions about the transportation of Hazardous/Dangerous Waste?
The Federal USDOT regulates the transportation of hazardous materials. The Washington State Patrol's Commercial Vehicle Division is the agency who issues permits and licenses and enforces the Federal Transportation regulations for transportation within Washington State. The phone number for the Commercial Vehicle Division is 360-753-0350.
For Federal USDOT inter-state transit information (transportation from state to state), call Motor Carrier Services at 800-467-4922. Additional information can be found at the following links:

Obtaining a RCRA Site ID number - When, who and why?
When:
WSDOT construction projects are typically Conditionally Exempt Small Quantity Generators because projects usually handle abandoned non-acute hazardous waste, which does not require a RCRA Site ID number. Non-acute dangerous/hazardous waste is determined by a toxicity characteristic leaching procedure (TCLP) test.
A RCRA Site ID Number is obtained when there is a potential to generate more than 220 pounds of non-acute dangerous/hazardous waste. For WSDOT projects, this typically includes bridge painting or removal projects but may also include projects that generate contaminated soils that exceed the TCLP threshold for dangerous waste.
Useful estimates for determining quantities are that a full 55 gallon drum of water weighs approximately 460 pounds. A full 55 gallon drum of compacted soil weighs approximately 882 pounds. These weights do not include the weight of the drum container which does not need to be included in the quantity.
Who:
It is recommended that a WSDOT Regional Environmental Office or Hazardous Materials Specialist obtain the RCRA Site ID Number. This will ensure that the proper documentation and tracking is completed, the annual report is filed, and the Site ID Number is closed.
Why:
The following links provide regulations and guidance information.
