Realty Agreement for Carbon Pollution-Free Projects at Savannah River Site

Released: March 8, 2024

Approved for Public Release

Disclaimer

• Savannah River Site requires submission of a Site Use Permit application prior to allowing any activity on any tract of land onsite

• The process provides a…

– method of informing various stakeholders of proposed plans for a tract of land to identify conflicts between the permit application and previously granted permits

– forum for impacted stakeholders to communicate concerns about or support for the application

– way to facilitate discussion between requestors and impacted stakeholders to establish guidelines and/or restrictions that allow the proposed usage to go forward

• A considerable amount of stakeholder engagement has established the boundaries of the potential sites for solar power generation that are presented in this document

• However, Site Use Permits have not yet been granted for any of the sites

• Approved permits may for example require or allow moving a boundary, relocating endangered species, providing access to monitoring stations, establishing buffer zones around wetlands, etc.

• The outcome of solar site permit applications will be available before lease negotiations begin

• Increased N&CSE analysis is required for permanent clearing of spaces within facility site boundaries.

– Facility site boundary radius is the shortest distance from the facility to the nearest SRS boundary.

– The facility site boundary is utilized for offsite receptor dose analysis.

• Solar Sites outside of the combined N&CSE facility site boundaries (blue overlay) will require less rigorous N&CSE analysis.

• No federally listed species

• No candidate species

• No sensitive plant species

• No perennial streams

• Four isolated wetlands (5.5 acres total) lack a suitable upland matrix needed for many species. Restoration unlikely and impact of development is acceptable relative to other solar sites.

• “Brown field” adjacent on west side provides opportunity for expansion of usable area.

• Directly accessible from SC125

• This tract is part of the SRS management area for the Red Cockaded Woodpecker (RCW), a federally designated endangered species

• While no RCW clusters are known currently, the boundary encroaches on foraging area of known clusters

• Carolina bay shown within the boundary is possibly an artifact of aerial imagery and must be confirmed.

• Buffer between the eastern boundary and Upper Three Runs Creek may need to be increased beyond what is shown.

• Area not frequently sampled and only one record of a candidate species (southern hognose snake) is from 1995.

• Mix of former agricultural land and undisturbed areas that have been maintained in good condition by burning.

• Access to a single monitoring area (blue square) must be available

• Directly accessible from US Hwy 278
