On Friday Feb 20, 2009 two administrative law judges refused to hear testimony on the impact of carbon dioxide emissions during the permitting process for the NRG Limestone coal-fired power plant. In protest, local environmentalists gathered for an 8:30 a.m. protest Monday Feb 22 outside the State Office of Administrative Hearings. Groups supporting the protest included: Public Citizen, Seed Coalition, Environment Texas, Clean Water Action, Re- Energize Texas, and the Texas Climate Emergency Campaign.
