d. DG-4026, Page 57 • Well structures (use, depth, diameter, construction, location, pumping rate or discharge rate for injection wells). • Supplemental water sources, onsite or offsite (location, design, construction and management). • Transportation infrastructure (e.g., location, extent, and number of roads, culverts, bridges, rail, barge slip, and barge facilities). • Other in- or over-water structures. • Transmission (e.g., location, extent, voltage, and number of existing transmission facilities, modifications to existing transmission facilities, use or modification of existing transmission corridors, new transmission corridors, new transmission lines, transmission structure types, and switchyards). 3.3 Building Activities Building activities, methods, and durations influence the environmental impacts of the proposed project. The applicant should describe the type of activities needed to build or install the proposed structures and associated facilities described in Section 3.2, and should indicate the sequencing and estimated duration of activities, especially when multiple units are proposed. The ER should include consideration of seasonal constraints on building activity. If multiple units are proposed or if the proposed project is co-located with an existing facility, the ER should include consideration of activities and workforce related to concurrent building and operation. The description of building activities in the ER should also include the following: • Applicants should be prepared to provide spatial data in electronic format (current industry- standard format) for the proposed plant (permanent as-built structures) and associated building uses (including temporary structures and use areas). • Maps or scale drawings showing the extent of area to be disturbed during building (both onsite and offsite) and the construction use of the site or project areas (e.g., laydown, spoils stockpile or disposal, concrete batch plant, module assembly,
