Texas plan to reduce haze in national parks wouldn’t require any new limits on pollution Fri, 07/02/2021 - 7:38pm Erin Douglas, The Texas Tribune Friday, July 2, 2021 Texas regulators on Wednesday advanced a plan for reducing pollution at its national parks that lacks any new limits on air pollutants that cause haze and disregards concerns voiced by federal agencies and environmentalists alike. Texas’ proposed plan — which is required by the federal government to improve visibility at national parks and other federally protected areas — would not require coal plants in Texas to do anything differently to reduce haze on the federally-managed lands. Environmentalists had hoped Texas would require the power plants, one of the largest contributors to haze, to install pollution-reducing technology, such as scrubbers, that most other states have required for several years.
