Important information

  • DC Water is working in cooperation with the National Park Service (NPS), the lead agency, to prepare an EA for the Soapstone Valley Park Sewer Rehabilitation Project, as required by the National Environmental Policy Act (NEPA).
  • NEPA regulations mandate that a review period is completed once the EA is made available to the public. At that time, stakeholders, such as Advisory Neighborhood Commissions (ANC), and the public will be notified.
