The organization Republicans for Environmental Protection singled out Domenici as "Worst in the Senate in 2006" on environmental issues. In addition to assigning Domenici a score of zero for his environmental voting record, the group issued him "environmental harm demerits" for what they saw as two particularly irresponsible acts: first, for spearheading efforts to include in federal budget legislation provisions for "speculative revenues from oil drilling in the Arctic National Wildlife Refuge; second, "for sponsoring and securing passage of S. 3711, the Gulf of Mexico Energy Security Act, which would perpetuate America's dangerous oil dependence, set a precedent for drilling in sensitive marine waters, and direct a disproportionate share of federal royalty revenues from a public resource to four states."
