Are alcoholic beverages regulated as hazardous waste when they exhibit the characteristic of ignitability?
Nevertheless, the alcohol exclusion is not limited to alcoholic bever ages or paints. The exclusion applies to all aqueous solutions containing less than 24% alcohol, even if additional non-alcoholic components are present. The term "alcohol" refers to any alcohol or combination of alcohols (55 FR 22520, 22543; June 1, l990). However, if the alcohol has been used for solvent properties and is one of the alcohols specified in EPA hazardous waste codes F001-F005, the waste must be evaluated to determine if it should be classified as an F-listed spent solvent waste.
What is the definition of aqueous for the purposes of determining whether a waste is corrosive?
There is no regulatory definition of aqueous however, for purposes of the corrosivity characteristic an aqueous waste is defined as the waste for which pH is measurable. Furthermore, Method 9040C in Test Methods for the Evaluation of Solid Waste, Physical/Chemical Methods (SW-846) is the appropriate test method to determine the pH of a waste. This method is used to measure the pH of aqueous wastes and those wastes where the aqueous phase constitutes at least 20% of the total volume of the waste. Therefore, any waste to which this method is applicable must contain at least 20% free water by volume.
How are representative sampling, confidence levels, and statistical analysis used to determine if a waste is hazardous?
A generator can either test his or her waste or apply knowledge of the waste to determine whether the waste is hazardous. If a generator decides to test the waste, testing should be done in accordance with the test methods set forth in 40 CFR Part 261, Subpart C.
