 Compass Datacenters IAD I LLC
Attn:  Mr. Jared Day
14180 North Dallas Parkway, Suite 610
Dallas, TX 75254

WATERWAY AND LOCATION OF THE PROPOSED WORK: The project is located on an approximately 144 acre parcel southwest of the Dulles Greenway (Route 267) and southeast of the intersection of Sycolin Road (Route 643) and Gulick Mill Road (Route 648), south of Leesburg in Loudoun County, Virginia.  The work will occur in tributaries to Goose Creek.

 PROPOSED WORK AND PURPOSE: The project consists of the discharge of fill material into waters of the United States associated with the construction of a data center facility at the subject location. The project is called Project IAD. Phase I (39 acres) was authorized by General Permit and is currently under construction.  Phase II includes an additional six data center buildings with associated equipment yards, road and utility infrastructure and stormwater management facilities for the final stage of the overall data center campus. Both Phases of the project will result in cumulative impacts to approximately 0.28-acre palustrine forested wetlands (PFO), 0.75-acre palustrine emergent wetlands (PEM), and 1,097 linear feet (0.29-acre) of stream beds will be permanently impacted by the proposed project.  An additional 0.04 PFO, 0.01-acre PEM and 86 linear feet (0.02 acre) of stream beds will be temporarily impacted.  Compensatory mitigation will be provided by the purchase of wetland and stream credits. 

In addition to the required Department of the Army permit, the applicant must obtain a Virginia Water Protection Permit from the Virginia Department of Environmental Quality (DEQ) assuring that applicable laws and regulations pertaining to water quality are not violated.  A vicinity map and project plans are attached.  This public notice and the drawings can also be viewed at

AUTHORITY: Permits are required pursuant to Sections 401 and 404 of the Clean Water Act (Public Law 95-217) and Title 62.1 of the Code of Virginia.

FEDERAL EVALUATION OF APPLICATION:  The decision whether to issue a permit will be based on an evaluation of the probable impact including cumulative impacts of the proposed activity on the public interest.  The decision will reflect the national concern for both protection and utilization of important resources.  The benefits which reasonably may be expected from the proposal must be balanced against its reasonably foreseeable detriments.  All of the proposal's relevant factors will be considered, including conservation, economics, aesthetics, general environmental concerns, wetlands, cultural values, fish and wildlife values, flood hazards, flood plain values, land use classification, navigation, shoreline erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs, consideration of property ownership and, in general, the needs and welfare of the people.  The Environmental Protection Agency's "Guidelines for Specification of Disposal Sites for Dredged or Fill Material" will also be applied (Section 404(b)(1) of the Clean Water Act). 

The Corps of Engineers is soliciting comments from the public; Federal, state, and local agencies and officials; Indian Tribes; and other interested parties in order to consider and evaluate the impacts of this proposed activity.  Any comments received will be considered by the Corps of Engineers to determine whether to issue, modify, condition or deny a permit for this proposal.  To make this decision, comments are used to assess impacts on endangered species, historic properties, water quality, general environmental effects, and the other public interest factors listed above.  Comments are used in the preparation of an Environmental Assessment and/or an Environmental Impact Statement pursuant to the National Environmental Policy Act.  Comments are also used to determine the need for a public hearing and to determine the overall public interest of the proposed activity.  Anyone may request a public hearing to consider this permit application by writing to the District Commander within 30 days of the date of this notice, stating specific reasons for holding the public hearing.  The District Commander will then decide if a hearing should be held.

Preliminary review indicates that:  (l) no environmental impact statement was prepared; (2) there may be an effect to listed/proposed/candidate species and/or designated/proposed critical habitat under the Endangered Species Act of 1973 and the Official Species List and Species Conclusion Table has been provided for review and comment by U.S. Fish and Wildlife Service; and (3) known properties eligible for inclusion or included in the National Register of Historic Places are near the permit area, however, would not be adversely affected by the proposal. The Permit Area and Area of Potential Effects consists of the entire parcel.  Additional information might change any of these findings.

PRIVACY AND CONFIDENTIALITY:  Comments and information, including the identity of the submitter, submitted in response to this Public Notice may be disclosed, reproduced, and distributed at the discretion of the U.S. Army Corps of Engineers.  Information that is submitted in connection with this Public Notice cannot be maintained as confidential by the U.S. Army Corps of Engineers.  Submissions should not include any information that the submitter seeks to preserve as confidential.

COMMENT PERIOD:  Comments on this project should be made in writing, addressed to the U.S. Army Corps of Engineers-Norfolk District, Northern Virginia Field Office, 18139 Triangle Plaza, Suite 213, Dumfries, VA 22026, or by email to and should be received by the close of business on October 9, 2018.
