Subchapter K - Alternative Requirements for Hazardous Waste Determination and Accumulation of Unwanted Material for Laboratories Owned by Eligible Academic Entities
Section NR 662.213 - Laboratory clean-outs

(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 or 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.

(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.
