6 CCR 1007-3-8.6 - Basis and Purpose

These amendments to 6 CCR 1007-3, Parts 260, 262, and 265 are made pursuant to the authority granted to the Hazardous Waste Commission in section 25-15-302(2), C.R.S.

Exports of Hazardous Waste: Technical Correction

On September 4, 1991, the Environmental Protection Agency (EPA) published a technical correction concerning the notification of intent to export. These revisions amend § 262.53 and § 262.56 originally introduced into the regulations by 51 FR 28664 (August 8, 1986), by changing the office to which the notifications of export activities must be sent, from the Office of International Activities to the Office of Waste Programs Enforcement. These amendments provide state equivalency with the regulatory requirements of the Environmental Protection Agency.

This Basis and Purpose incorporates by reference the preamble language for the Environmental Protection Agency regulations published in the Federal Register at 56 FR 43704-43705, September 4, 1991.

Amendments to Interim Status Standards for Downgradient Ground-Water Monitoring Well Locations at Hazardous Waste Facilities

On December 23, 1991, the Environmental Protection Agency (EPA) promulgated a final rule implementing amendments to § § 260.10 and 265.91. These amendments allow facilities to install alternate ground-water monitoring wells at interim status facilities where existing physical obstacles prevent installations at the limit of the waste management area. Today's rule provides that the owner or operator of an existing facility may demonstrate that an alternate hydraulically downgradient monitoring well location will meet several criteria. This demonstration must be certified by a qualified ground-water scientist. Today's rule also promulgates a definition of "qualified ground-water scientist." These amendments provide state equivalency with the regulatory requirements of the Environmental Protection Agency.

This Basis and Purpose incorporates by reference the preamble language for the Environmental Protection Agency regulations published in the Federal Register at 56 FR 66365-66369, December 23, 1991.
