Even when not required by regulations, the following best practices are recommended.
- Retain records of analytical data that is used in making waste determinations for a minimum of three years; keep these files in an organized manner so they are easy to find.
- Develop a filing system for waste determination files, sorted by waste stream.
- Ensure that waste determination is confirmed by the generator, even if an outside company performs the analysis and renders an opinion of the waste determination.
- Avoid mixing waste in the same container, which can result in a waste classification for the entire volume of waste that is not necessary.
- Review your waste determination process every six months at a minimum to evaluate whether these determinations are accurate and consistent.
