7045.0215 TIMING OF WASTE EVALUATION.
Individual wastes; combined wastes.
Waste evaluation must be of the individual waste prior to any mingling or combining with other wastes. If wastes are subsequently mingled or combined, except for wastes that are mingled or combined in a sewer system, the generator must also evaluate the waste resulting from the mingling or combining within 60 days of the act of mingling or combining. Failure to do so means that the commingled or mixed waste must be managed as a hazardous waste and the person who produces the waste must be considered a generator until the waste is determined to be nonhazardous under parts 7045.0214 to 7045.0218.
The person must reevaluate the waste whenever the person has reason to believe that the composition of the waste is altered so that the results of the previous evaluation are no longer representative of the waste.
A person who produces two or more wastes that are substantively identical or are from substantively identical processes, such that one waste is representative of the other wastes, may use one evaluation for all such wastes.
