January 23, 2015 Mr. Marcel Acosta, AICP Executive Director National Capital Planning commission 401 9th Street, NW North Lobby, Suite 500 Washington, DC 20576 Attention: Mr. Shane Dettman Senior Urban Planner RE: Construction of (two) Buildings on BARC’s property Dear Mr. Dettman: The Henry A. Wallace Beltsville Agricultural Research Center (BARC), Agricultural Research Services (ARS), United States Department of Agriculture (USDA) is submitting information of a partnership with the University of Maryland, University- College of Agriculture- Agricultural Experiment Station. The University of Maryland has been granted permission by BARC to construct (two) additional structures in support of its ongoing research activities on BARC’s government owned property for the National Capital Planning Commission (NCPC) review and approval.

The Storage building (50 ft. x 100 ft.) will be used for equipment storage. University of Maryland currently have a large amount of farm equipment which is stored outside and exposed to inclement weather which results costly repair work. Due to the amount of research work that we do, we have a larger amount of specialized equipment for these plots which must be stored inside.

The Fertilizer building (20 ft. x 36 ft.) will be used to store two types of fertilizer as well as lime which will be used on the fields that we farm. Currently the University of Maryland dumps the fertilizer mostly inside but must push the rest in with a skid loader. The lime is dumped outside and then must be carried inside with the skid loader. With this new building the fertilizer and lime will be able to be dumped directly into the building without having to push it in and related logistic issues.

In accordance with the National Environmental Policy Act of 1969, a NEPA report has been attached for your review. Also included is a photo, drawings and the Categorical Exclusion for the construction.

BARC would like to submit this project under the NCPC Guidelines and Submission Requirements for Section 7, Delegation of Authority to Executive Director of Federal Property in the National Capital Region for your review. I look forward the Commission’s response regarding this project. Please contact me at the BARC, Real Property Section should you have any questions regarding this submission. I can be reached at 301-504-5221. Thank you in advance. Sincerely,

All wooden components of the building that are not pressure treated and would otherwise be exposed to weather shall be covered by the metal siding, roofing, metal trim or painted. Color samples shall be submitted to the Project Engineer for selection; written approval of the color selection must be received from the MAES before inclusion in the construction.

Summary of Findings and Conclusions ALTERNATIVES TO THE PROPOSED ACTION Alternatives and Project Modifications Considered [24 CFR 58.40(e), Ref. 40 CFR 1508.9] (Identify other reasonable courses of action that were considered and not selected, such as other sites, design modifications, or other uses of the subject site. Describe the benefits and adverse impacts to the human environment of each alternative and the reasons for rejecting it.)

No Action Alternative [24 CFR 58.40(e)]

(Discuss the benefits and adverse impacts to the human environment of not implementing the preferred alternative).

Mitigation Measures Recommended [24 CFR 58.40(d), 40 CFR 1508.20]

(Recommend feasible ways in which the proposal or its external factors should be modified in order to minimize adverse environmental impacts and restore or enhance environmental quality.) Additional Studies Performed (Attach studies or summaries)

List of Sources, Agencies and Persons Consulted [40 CFR 1508.9(b)]

Environmental Impact Notes/Comments The following information and attached drawings are provided to support that the proposed work at the “UMD-Beltsville Facility (Beaver Dam Road) Construction of New Storage Building” will not have a negative impact to the environment. The intent of the construction of these buildings is to aid in the functionality of the agricultural environment in which they will be surrounded. Please note: the buildings are independent of one another; each one has its own function to serve the facility. Our office understands that storm water runoff in urban areas is a major contributor to water pollution in the United States. However, this is an agricultural environment with an existing 21,865 square feet of impervious area (buildings, concrete pads, paving) in the center of 287 acres of farmland. The proposed buildings will bring the total up to 27,945 square feet, including concrete work (please see drawing E1). The proposed project site is fortunately located in an area where surface runoff is naturally minimized. Drawing E2 shows the acreages of the surrounding areas of the site. Drawing E3 shows an aerial view showing that there are already trees in the immediate area providing canopy interception, immediately to the west there are crop fields conveniently graded, crop fields to the south, and partially fields on the east. The location combined with the amount of area disturbed lends this to be a project that is minimally low in impact to the environment. This project complies with NEPA’s Categorical Exclusion 23 CFR 771.117(a), this project will not:

Induce significant impacts to planned growth or land use for the area

Require the relocation of significant numbers of people

Have a significant impact on any natural, cultural, recreational, historic or other resource

Involve significant air, noise, or water quality impacts

Have significant impacts on travel patterns

MEMORANDUM FOR THE RECORD 08 January, 2015 To: The Project File From: SOHES

Subject: CATEGORICAL EXCLUSION FOR THE CONSTRUCTION OF UP TO TWO NEW STORAGE BARNS BY THE UNIVERSITY OF MARYLAND ON BARC PROPERTY FOR EQUIPMENT STORAGE

References: (a) THE WHITE HOUSE, COUNCIL ON ENVIRONMENTAL QUALITY, CEQ 40 CFR 1500-1508 (b) UNITED STATES DEPARTMENT OF AGRICULTURE USDA 7 CFR l b (c) AGRICULTURAL RESEARCH SERVICE ARS 7 CFR 520 (d) ARS 242.1 FACILITY DESIGN STANDARDS

(e) Manual 160.0M-ARS - Safety, Health and Environmental 1. Per references (a-e) subject action has been reviewed under USDA procedures for implementing the National

Environmental Policy Act (NEPA). A determination that the proposed action is recommended to be categorically excluded from additional NEPA review and documentation based on the evaluation of the effect of the proposed action on the human environment. However, additional information prior to construction will be required to determine if any cultural resources may be present in the footprint of the proposed structure for potential future construction/demolition activities that might take place at this location.

2. Proposed action. The project calls for the construction of two pre-engineered buildings. Building A: Construct a pre-

engineered building (50’ x 100’ – height from bottom of truss to finished floor 20’ minimum), enclosed on three sides; and B: Additive Alternate 1 (Add. Alt.1), accomplish the following: Construction of a second, pre-engineered composite (concrete, wood, metal) building (20’ x 36’ – height from bottom of truss to finished floor 20’ minimum), enclosed on three sides.

3. Anticipated Environmental Impacts. The anticipated environmental impacts associated with the improvements at the

UMD research area are minimal. The two new structures will provide additional storage and protection of equipment from weather.

4. Environmental Justice Determination: In accordance with Executive Order 12898, this action will not have any

impact to minority or economically disadvantaged populations in the region. 5. After full consideration this project has been determined not to have a significant environmental impact on the

quality of the human health or natural resources, including public health, security, safety, nor that of any threatened or endangered species.

6. Decision/Finding. The proposed action has been reviewed and it has been determined that it meets the criteria for

Categorical Exclusion mentioned in references (a-e) and may be excluded from further documentation under NEPA. The proposed modernization is within the existing area support buildings used by the UMD, and will remain substantially unchanged, and the use is consistent with applicable regulations.
