Trigo North Impact Area EA

The U.S. Army Garrison Yuma Proving Ground prepared an Environmental Assessment (EA) to analyze the impacts associated with the establishment and use of a Research, Development, Testing, and Evaluation impact area in the North Trigo area at Yuma Proving Ground. The proposed Trigo North Impact Area would be approximately 88 acres and would accommodate current and future weapon’s development associated with artillery test activities, by providing additional space for longer ranges and wider safety buffers. Based on the analysis presented in the EA, the Proposed Action would not result in significant environmental impacts and USAG YPG has prepared a Draft Finding of No Significant Impact (FNSI). The EA and draft FNSI are available for your download and review.
