A judge in Austin will consider challenges to his blocking of a proposal that could allow dozens of states to dump radioactive waste in far West Texas.
Last week's temporary restraining order issued by State District Judge Jon Wisser sided with environmentalists.
Wisser planned a hearing Monday on the injunction against the Texas Low-Level Radioactive Waste Disposal Compact Commission.
The commission on Tuesday was scheduled to vote on rules to expand how much waste could be processed at a dump in remote Andrews County.
Environmentalists, who sought last Thursday's court ruling, have accused regulators and Dallas-based Waste Control Specialists of rushing through the dump expansion proposal during the holidays. A company spokesman denies the allegations.
The site currently accepts waste from Texas, Vermont and the federal government.
