EPA invites public comment on the engineering evaluation/cost analysis for the Potomac Yard Site.
The U.S. Environmental Protection Agency (EPA) has released an Engineering Evaluation/Cost Analysis (EE/CA) to address contamination at the Potomac Yard Site in Alexandria, Virginia. The EE/CA analyzes removal actions available to address the drainage outfalls from the North Yard, North Yard Tail, and Potomac Greens areas of the Site. These outfalls are the pathways by which contaminants could travel from the Site into two local waterways, Four Mile Run and the Potomac River. The EE/CA outlines five actions and highlights recommended actions to address the movement of contaminants from the Site.
EPA evaluated the following five actions for each of the three areas at the Site: No Action; Temporary Sediment Controls (i.e., silt fence, check dam, rip rap); Sediment Removal from Ditches and Pipes; Regrading Ditches and Closing Outfalls (eliminating the use of existing outfalls); and Regrading Ditches and Rerouting Stormwater (continued use of outfalls)
The EE/CA recommends the following actions:
- North Yard
- North Yard Tail
- Potomac Greens (North and Middle Pond Ditches)
- Potomac Greens (South Pond Ditch) No Action (Development of the Site will close existing outfalls within 6 months.)
- Regrading Ditches & Closing Outfalls
- Regrading Ditches & Rerouting Stormwater
- Temporary Sediment Controls
EPA will hold a public comment period on the EE/CA. Representatives from EPA will address comments on the EE/CA and the recommended actions. Before selecting a final removal action, EPA will consider all comments submitted in writing during the comment period. No public meeting is planned at this time. If EPA receives a substantial number of requests for a public meeting, then representatives from EPA will arrange a meeting.
