Section 30.103 - Hazardous Waste Numbers(1) A hazardous waste which is identified by one or more characteristics in 310 CMR 30.120 through 30.125 is assigned every EPA Hazardous Waste Number that is applicable as established pursuant to 310 CMR 30.120 through 30.125. Except as indicated in 310 CMR 30.103(3), each applicable Hazardous Waste Number shall be used in complying with the notification requirements of 310 CMR 30.060 through 30.064 and all applicable recordkeeping and reporting requirements prescribed in 310 CMR 30.300 through 30.900.(2) Each hazardous waste listed in 310 CMR 30.130 through 30.136 is assigned a Hazardous Waste Number which precedes the name of the waste. This number is either an EPA Hazardous Waste Number or a Massachusetts Hazardous Waste Number. This number, in addition to any Hazardous Waste Numbers applicable to the waste pursuant to 310 CMR 30.103(1), shall be used in complying with the notification requirements of 310 CMR 30.060 through 30.064 and all applicable recordkeeping and reporting requirements prescribed by 310 CMR 30.300 through 30.900.(3) As specified in 40 CFR 268.9(b) and as incorporated by reference at 310 CMR 30.750, for a waste subject to 310 CMR 30.750 that is both listed under 310 CMR 30.130 through 30.136 and exhibits a characteristic under 310 CMR 30.120, the treatment standard for the waste code listed under 310 CMR 30.130 through 30.136 will operate in lieu of the standard for the waste code under 310 CMR 30.120, provided that the treatment standard for the listed waste includes a treatment standard for the constituent that causes the waste to exhibit the characteristic. Otherwise, the waste must meet the treatment standards for all applicable listed and characteristic waste codes.
