I-5 Interstate Bridge Over Columbia River
In Summer 2008, a Draft Environmental Impact Statement (DEIS) was released on the Columbia River Crossing Project, and various environmental organizations, including Rosemere Neighborhood Association, submitted public comment to show that the draft document was incomplete and full of data gaps. Concerns were also raised regarding the draft’s compliance with the National Environmental Policy Act.
Since the release of the DEIS, Rosemere has met several times with Columbia River Crossing (CRC) staff and has raised concerns regarding the project’s impact on the environment, including the aquifer system that provides Clark County residents with drinking water and local streams within the construction footprint.
In 2005, Rosemere submitted a petition to EPA requesting that agency to designate the Troutdale and Unconsolidated Alluvium Aquifer System in Clark County, Washington, as a Sole Source Aquifer. The EPA defines the Sole Source Aquifer Program as a tool used to protect drinking water supplies in areas with few or no alternative sources to groundwater resources, and where such an aquifer is vulnerable to contamination. Sole Source designation requires at least a 50% dependence on an aquifer for its potable water supply. Factual analysis provided by Rosemere and its partners shows that 99.4% of the potable water used in Clark County is obtained from groundwater. In August, 2006, EPA officially granted Rosemere’s petition and designated Clark County’s Troutdale Aquifer System as a federally protected Sole Source Aquifer. One of Rosemere’s goals was to ensure adequate environmental review of the CRC project under the federal Sole Source Aquifer program.
