Alternative #4, the Royal Palms option, is the recommended alternative. It would consist of an average of 10 trucks per day (about 40 trucks per day maximum) for 6–9 months during the shaft construction. There would be approximately 5 to 10 construction workers on site for a 10-hour shift per day, 5 days per week, for approximately 2 years to construct the exit shaft, manifold, valves, and piping interconnections. Demobilization of the site would take about 3 months.

Air quality would be significantly impacted during construction. Alternatives 1, 3, and 4 would exceed thresholds for volatile organic compounds (VOC) and nitrogen oxides (NOX), and Alternative 2 would exceed thresholds for VOC, carbon monoxide (CO), and NOX.
