The federal government is seeking public input before it does another environmental analysis of potential effects of more drilling on the Roan Plateau.
    
A federal judge last year said the Bureau of Land Management failed to fully consider cumulative impacts on air quality when it approved drilling on the biologically rich plateau in northwest Colorado. She also said it failed to fully address potential ozone impacts and a proposal that would've left much of the surface of the plateau undisturbed by drilling.
    
Her ruling is prompting a new environmental analysis. But first, the BLM is hosting open house meetings Wednesday in Silt and Thursday in Grand Junction to help identify what should be addressed in the supplemental environmental impact statement for the plateau.
