​The intent of compliant hazardous waste management is to provide cradle-to-grave responsibility for hazardous wastes to ensure that these wastes are not mismanaged in a way that will impact human health or the environment.

To comply with Iowa's hazardous waste requirements, you must follow the steps below:
1.Determine whether any hazardous waste is generated.
2.Track how much hazardous waste is generated on a monthly basis to determine your facility's generator status.
3.Manage hazardous waste and recordkeeping in accordance to the amount of waste generated.

Every business must determine whether its wastes are hazardous or non-hazardous. Proper waste characterization is essential in determining applicable waste handling and disposal options.  

Automotive salvage facilities have many wastes that are potentially hazardous. Some of these wastes have regulations that make them exempt from hazardous waste management rules when properly handled to encourage recycling of the waste. Used Oil is a good example of this exemption.

Other waste may or may not be hazardous. A hazardous waste determination must be made for these wastes. Used antifreeze, waste oil absorbent such as used floor dry, and sump sludge from a floor drain sump pit are automotive wastes that require a determination as either hazardous or non-hazardous before choosing a disposal option. 

An analytical laboratory test or a demonstration of thorough knowledge (such as information obtained from the SDS or a recent study) can make that determination. To make a hazardous/non-hazardous determination using lab testing, a one-time representative sample of the waste must be collected and sent to a lab for analysis. The procedure that can make a hazardous waste determination is called the Toxicity Characteristic Leaching Procedure or TCLP test. 

An accurate analysis of automotive waste must include testing for the parameters that are likely to be present in the waste, such as the eight (8) heavy metals and the common Volatile Organic Compounds (VOCs).
