Antifreeze was added to this rule in 2016. Since that time, the Division of Waste Management and Radiation Control (Division) has learned that propylene glycol is frequently used as a substitute for ethylene glycol in low toxicity, environmentally friendly automotive antifreeze. The Division is aware that auto repair and maintenance shops do not discriminate between ethylene glycol and propylene glycol when flushing radiators so both chemicals are mixed together in collection containers prior to being recycled or disposed. In order to continue to encourage the recycling of waste antifreeze and avoid any potential compliance issues at facilities where the two chemicals are mixed together, the Division is adding propylene glycol to the definition of antifreeze at Subsection R315-273-9(c). Language found in Sections R315-273-10 and R315-273-30 that exempts generators from having to register their lamp crushers is being deleted from this rule. No justification can be found for this exemption and a recent review of this rule determined that this exemption does not meet the intent of this rule which is to have all lamp crushers registered. Subsections R315-273-13(d)(3)(i) and R315-273-33(d)(3)(i) require the accumulation container used with a drum top lamp crusher to be designed specifically for crushing lamps. No such container exists. Instead, drum top lamp crushers are designed to be attached to open top 55-gallon drums. Therefore, the language is being changed to state that the handler should use an accumulation container specified by the manufacturer of the lamp crusher. Language found in Subsections R315-273-13(d)(3)(iii) and R315-273-33(d)(3)(iii) specifying that a lamp crusher shall have a bag filter followed by a HEPA filter and an activated carbon filter is being changed to state that this configuration is the minimum requirement. Many lamp crushers have more filters than the three specified in this rule and the Division does not want to exclude handlers from using lamp crushers with more than three filters. The term �Waste-antifreeze� is being deleted from Subsections R315-273-14(f) and R315-272-34(f) to allow facilities managing waste antifreeze to use this term to label containers of waste antifreeze that is not being managed as a hazardous waste or as a universal waste. A typographical error is being fixed at Subsection R315-273-6(a) where the subsections were numbered (1), (2), and (4). The 4 is being changed to a 3. Typographical errors at Subsections R315-273-14(f) and R315-273-34(f) where there are extra spaces in the terms �Universal Waste-antifreeze�. The extra spaces are being deleted.
