Hello and thank you for coming to Just Answer. We appreciate the opportunity to help you with your questions. First of all, I need to warn you that waste disposal regulations are complex, depend on your specific circumstances, and carry legal consequences if not followed properly. Therefore, while I will answer your question, I will also provide some EPA references that I recommend that you at least review to ensure that your specific circumstances aren't covered by specific requirements or that your specific circumstances don't exempt you from some requirements.
According to 40 CFR Parts 264/265, Subpart A-E), as explained in the EPA Training module that I will provide a link to for you, unless the TSDF is exempt from the requirements of Parts 264/265 (exemptions are listed in the manual) "TSDFs need to verify the composition (i.e., hazardous constituents and characteristics) of incoming waste in order to treat, store, or dispose of the waste properly. A waste analysis plan
(WAP) outlines the verification procedures, including specific sampling methods, necessary to ensure proper treatment, storage, or disposal (§264/265.13). The WAP must be written and kept on site."
The training manual is very well written in fairly plain language. It can be found at
Training manual .
Here is a training manual for waste analysis for TSDFs. Waste Analysis
Hopefully, this information will be helpful to you. Please let me know if you need more information about this question.
