Pepco Benning Road Facility Plans and Deliverables
Background
In January 2011, Pepco and DOEE signed a Consent Decree that detailed Pepco's agreement to evaluate environmental conditions at the Benning Service Center site and adjacent portions of the Anacostia River. Pepco will perform this evaluation (known as a "Remedial Investigation/Feasibility Study"), with DOEE's oversight. The first part of the evaluation will investigate conditions at the Site and adjacent shoreline areas and river sediments to determine if historical operations at the site have contributed to contamination of river sediments, and to assess any impacts to human health and the environment from existing conditions at the site and adjacent portions of the river. The final phase of the evaluation will identify options for addressing contamination within the study area for consideration by DOEE.
Pepco's Landside Feasibility Study (FS) for Benning Road Facility
This document addresses remedial alternative for the landside area (OU1). A separate Focused Feasibility Study is being prepared for the waterside area (OU2). This Landside (OU1) FS evaluates potential remedial actions for all areas of the Landside Investigation Area where risks exceed the cancer risk threshold of 1E-05 (a target risk selected for the Site consistent with the ARSP target risk level) and/or the non-cancer hazard index (HI) threshold of 1. DOEE solicited public comments on the OU1 FS from December 5, 2023 through February 6, 2024. Also, DOEE and Pepco held a community meeting on December 9, 2023. Pepco revised the OU1 FS as detailed in the Responses to Public Comments Matrix.
