It is important to know that any banks or financial institutions that are having unlicensed haulers clean out houses and hauling hazardous waste with their knowledge are also civilly and criminally responsible. Hiring unlicensed haulers, which includes sub-contractors, is in violation of the law in California. Financial institutions, asset management companies and real estate companies and their agents who are contracting for the removal of the hazardous waste are the generators of the hazardous waste and must hire licensed hazardous waste haulers. Up until the request is made for hazardous waste to be removed from a location materials are generally considered hazardous materials and another set of laws deals with storage of hazardous materials depending on quantity, volume and type. A company must be on the California State Department of Toxic Substances Control (DTSC) licensed hauler list to be able to transport hazardous waste. A company which does not normally transport hazardous waste may also be able to qualify as a Conditionally Exempt Small Quantity Generator (CESQG), but still need to adhere to transportation requirements and must still register with DTSC. Please refer to the below DTSC for specific information and guidelines.
These websites and associated documents are very comprehensive and will provides options for handling, transporting and disposing of hazardous waste from foreclosed homes. Much depends on the volume of hazardous waste hauled and what is being hauled.
I hope these websites will be of some benefit in the meantime:
