Page 135 of 145

Construction laydown areas will be provided on the site proper as shown in Figure 54 – Construction Laydown Locations. These laydown areas will be used for storage, staging, parking, and miscellaneous equipment assembly tasks. The following summarizes the functional purpose of each Laydown Area.

Laydown Area “A” – Reserved for construction parking, material storage, topsoil stock piling, and storage of small ancillary equipment.

Laydown Area “B” – Reserved for short-term storage of sand, gravel, topsoil, and excavated material. This area will also be used for long term storage and pre-staging of large equipment and pipe rack modules. Of which, equipment will be “dressed” and preassembled with its shipped loose components to the greatest extent possible prior to installation. This will improve personnel safety by keeping as much work close to the ground as possible. Prior to the arrival of large pipe rack modules, the existing overhead transmission lines at the west property boundary between Laydown Area “B” and Highway 12 will need to be buried underground to achieve proper overhead clearances for equipment receiving.

Laydown Area “C” – Reserved for short term construction material storage, topsoil stockpiling, and short-term storage of small ancillary equipment. Laydown Area “D” – Reserved for short term storage and final staging of large equipment, small ancillary equipment, and pipe rack modules. Area also used as primary site entrance access for construction vehicles. This area may be used to “dress” and pre-assemble equipment with its shipped loose components to the greatest extent possible prior to installation.

Temporary Warehouse Laydown Yard – Small storage yard reserved for construction materials and

ancillary equipment that are fully assembled and do not require pre-staging work.

A temporary warehouse structure will be erected in the abandoned contractor parking lot area located west of the current contractor parking lot in the southwest corner of the existing power generation station’s campus. The temporary warehouse will be furnished with adequate climate control measures (where required), lights, telephone service, and broadband internet access for receiving and inventory control. The
