Laboratory clean-outs

Laboratory clean-outs. (1) One time per 12-month period for each laboratory, an eligible academic entity may opt to conduct a laboratory clean-out that is subject to all the applicable requirements of this subchapter, except that: (a) If the volume of unwanted material in the laboratory exceeds 55 gallons, or 1 quart of liquid reactive acutely hazardous unwanted material, or 1 kg of solid reactive acutely hazardous unwanted material, the eligible academic entity is not required to remove all unwanted materials from the laboratory within 10 calendar days of exceeding 55 gallons, or 1 quart of liquid reactive acutely hazardous unwanted material, or 1 kg of solid reactive acutely hazardous unwanted material, as required under s. NR 662.208 . Instead, the eligible academic entity shall remove all unwanted materials from the laboratory within 30 calendar days from the start of the laboratory clean-out. (b) For the purposes of on-site accumulation, an eligible academic entity is not required to count a hazardous waste that is an unused commercial chemical product that is listed in subch. D of ch. NR 661 or a hazardous waste exhibiting one or more characteristics listed in subch. C of ch. NR 661 that is generated solely during the laboratory clean-out toward its hazardous waste generator category, according to s. NR 662.013 . An unwanted material that is generated prior to the beginning of the laboratory clean-out and is still in the laboratory at the time the laboratory clean-out commences shall be counted toward the hazardous waste generator category, according to s. NR 662.013 , if it is determined to be hazardous waste. (c) For the purposes of off-site management, an eligible academic entity shall count all its hazardous waste, regardless of whether the hazardous waste was counted toward generator category under par. (b) , and if it generates more than 1 kg/month of acute hazardous waste or more than 100 kg/month of non-acute hazardous waste, the hazardous waste is subject to all applicable hazardous waste regulations when it is transported off-site. (d) An eligible academic entity shall document the activities of the laboratory clean-out. The documentation shall, at a minimum, identify the laboratory being cleaned out, the date the laboratory clean-out begins and ends, and the volume of hazardous waste generated during the laboratory clean-out. The eligible academic entity shall maintain the records for a period of 3 years from the date the clean-out ends. (2) For all other laboratory clean-outs conducted during the same 12-month period, an eligible academic entity is subject to all the applicable requirements of this subchapter, including all of the following: (a) The requirement to remove all unwanted materials from the laboratory within 10 calendar days of exceeding 55 gallons, or 1 quart of reactive acutely hazardous unwanted material, as required under s. NR 662.208 . (b) The requirement to count all hazardous waste, including unused hazardous waste, generated during the laboratory clean-out toward its hazardous waste generator category, according to s. NR 662.013 .
