These amendments to 6 CCR 1007-3, Part 268 are made pursuant to the authority granted to the Solid and Hazardous Waste Commission in § 25-15-302(2), C.R.S.
Revision of Land Disposal Treatment Standards for Carbamate Wastes
These amendments revise the Land Disposal Restrictions (LDR) treatment standards for hazardous wastes from the production of carbamates and carbamate commercial chemical products, and off-specification or manufacturing chemical intermediates and container residues of these materials that become hazardous wastes when they are discarded or intended to be discarded. Currently, under the LDR program, most carbamate wastes must meet numeric concentration limits before they can be land disposed. However, the lack of readily available analytical standards makes it difficult to measure whether the numeric LDR concentration limits have been met. These amendments modify the Table of Treatment Standards in § 268.40 of the Regulations to provide the use of the best demonstrated available technologies (BDAT) as an alternative standard for treating these wastes. In addition, these amendments remove carbamate Regulated Constituents from the Table of Universal Treatment Standards in § 268.48 of the Regulations.
This rulemaking applies to generators and treatment, storage and disposal facilities (TSDFs) managing EPA hazardous waste codes: K156, K157, K158, K159, K161, P127, P128, P185, P188, P189, P190, P191, P192, P194, P196, P197, P198, P199, P201, P202, P203, P204, P205, U271, U278, U279, U280, U364, U367, U372, U373, U387, U389, U394, U395, U404, U409, U410, and U411. This rulemaking also applies to generators and TSDFs of ignitable, corrosive, reactive and toxic hazardous wastes that are reasonably expected to contain one or more of the carbamate constituents listed above as underlying hazardous constituents at the point of the waste's generation.
This Basis and Purpose incorporates by reference the applicable portions of the preamble language for the EPA regulations as published in the Federal Register at 76 FR 34147-34157, June 13, 2011. These amendments are considered to be neither more nor less stringent than the current regulations, and Colorado is not required to modify its regulations to adopt these amendments.
