"We appreciate the EPA's work to analyze and determine the environmental impact of a proposed machine gun range project at Camp Edwards on Joint Base Cape Cod--an important review that we requested in April 2021 to ensure that Cape Cod's sole-source aquifer is not harmed by development activities. As JBCC is a critical part of the Cape Cod community, we urge JBCC to continue to work collaboratively with local officials and concerned residents to protect Cape Cod's sole-source aquifer from contamination. We look forward to EPA's engagement with stakeholders and our community through the 60-day public comment process."
