The Colorado Department of Public Health and Environment has been working collaboratively with the National Park Service, EPA Region 8 and numerous stakeholders to address the deleterious impacts of nitrogen deposition in Rocky Mountain National Park. As a result, a plan to reduce nitrogen deposition has been developed and endorsed by the three agencies and will be implemented to achieve resource management goals over a 25 year period. The presentation will summarize the plan and the action measures and provide and overview of how sound science was incorporated into the administrative process.
