RMPJC was founded with a main focus of closing down the Rocky Flats nuclear plant. In coordination with AFSC Denver, Greenpeace, and numerous other organizations, RMPJC worked to end the production of potentially harmful nuclear waste. Over time, RMPJC became the foremost peace and environmental group working steadily for the best possible procedures to properly clean up the already thoroughly contaminated site. However, due to an improper “clean up” by government agencies, the efforts to clean up Rocky flats and make it habitable once again is still underway.
