"The launch mount would be elevated up to approximately 30 m to reduce excess

recirculation and erosion from rocket exhaust. A flame diverter would be constructed instead of a flame

trench as is currently used at the Falcon launch mount. The flame diverter would be composed of metal

piping similar in construction to the SLC-40 water-cooled diverter. It would measure approximately 20 m

wide by 20 m tall and be positioned directly under the rocket. It would divert the heat and rocket exhaust

plume away from the launch pad and commodities."



"SpaceX would also construct a landing pad for potential future launch vehicle returns within the LC-39A

boundary. The landing pad location would be inside the LC-39A fence line. SpaceX is still determining the

exact location of the landing pad, but it is tentatively planned for the area southeast of the new launch

mount. The landing pad would be approximately 85 m in diameter and similar to the existing LZ-1 landing

pads on CCAFS. "



"The new methane farm would accommodate a total capacity of approximately 2 million kg.

Approximately 1.5 million kg of liquid nitrogen would also be stored in the methane farm. The liquid

nitrogen is a cryogenic and would be used to cool the methane. The methane and nitrogen farm would

require lighting similar to the existing RP-1 farm located at LC-39A. If a new methane flare stack is

needed, the flare would be approximately 30 m tall. The flare stack and any required anchors would be

contained inside the construction project area. There are no planned modifications to the existing LOX

farm capacity; however, as the program develops, an additional tank and piping may need to be installed

to support the Proposed Action."
