Subpart K - ALTERNATIVE REQUIREMENTS FOR HAZARDOUS WASTE DETERMINATION AND ACCUMULATION OF UNWANTED MATERIAL FOR LABORATORIES OWNED BY ELIGIBLE ACADEMIC ENTITIES
Section 61-79.262.K.213 - Laboratory clean-outs

(1) If the volume of unwanted material in the laboratory exceeds fifty-five (55) gallons (or one (1) quart of liquid reactive acutely hazardous unwanted material or one (1) kilogram of solid reactive acutely hazardous unwanted material), the eligible academic entity is not required to remove all unwanted materials from the laboratory within ten (10) calendar days of exceeding fifty-five (55) gallons (or one (1) quart of liquid reactive acutely hazardous unwanted material or one (1) kilogram of solid reactive acutely hazardous unwanted material), as required by section 262.208. Instead, the eligible academic entity must remove all unwanted materials from the laboratory within thirty (30) calendar days from the start of the laboratory clean-out; and

(2) 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 (listed in R.61-79.261, subpart D or exhibiting one or more characteristics in R.61-79.261, subpart C) generated solely during the laboratory clean-out toward its hazardous waste generator category, pursuant to R.61-79.262.13. 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 must be counted toward hazardous waste generator category, pursuant to R.61-79.262.13, if it is determined to be hazardous waste; and

(3) For the purposes of off-site management, an eligible academic entity must count all its hazardous waste, regardless of whether the hazardous waste was counted toward generator category under paragraph (a)(2) of this section, and if it generates more than 1 kg/month of acute hazardous waste or more than 100 kg/month of non-acute hazardous waste (i.e., the very small quantity generator limits as defined in R.61-79.260.10), the hazardous waste is subject to all applicable hazardous waste regulations when it is transported off-site; and

(4) An eligible academic entity must document the activities of the laboratory clean-out. The documentation must, 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 must maintain the records for a period of three years from the date the clean-out ends; and

(1) 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 by 262.208; and

(2) The requirement to count all hazardous waste, including unused hazardous waste, generated during the laboratory clean-out toward its hazardous waste generator category, pursuant to R.61-79.262.13.
