I. Phase I - West ramp lighting pad access roads

A. Prior to beginning work the contractor shall contact Selfridge Environmental Management Office to obtain most recent soil and/or groundwater analytical data for determining contractor personnel risk exposures and personal protective equipment, if required

B. Prepare site as necessary to insure a properly graded road.

During earth work operations of this work contractor shall adhere to the following guidance:

If impacted soil controls cannot be maintained (excavated, stockpiled, reused, graded and seeded, and/or placed back at excavation area as fill or discharged to adjacent grassy area for infiltration, not allowed into storm water or sanitary sewers) within the contaminated delineated boundaries, follow General Specs 02 61 00 Removal and Disposal of Contaminated Soil.

Soil erosion permit and approved plan required as soil disturbance activities within 500 feet of wetlands.

Soil erosion plan in accordance with Selfridge Design Standards (2017).

Soil erosion best management practices must be established and maintained in accordance with Macomb County Macomb County Soil Erosion and Sedimentation Control Ordinance, adopted 16 August 2007 and Selfridge Design Standards (2017).

Catch basin and/or storm water conveyance temporary measures may be required.

Dust control for fugitive emissions must be included in soil erosion BMPs.

Any dewatering of non-contaminated/impacted groundwater or surface water infiltration will be discharged by pumping through a filter sock/dewatering bag and allowed to infiltrate into the surface vegetation and soils, in accordance with Selfridge Design Standards (2017).

Groundwater activities must be in accordance with Crock Wells and Groundwater Wells Guidance for SANGB (dated 2002-05-03).

Excess soil can be managed by backfilling native material or berming and seeding in the local vicinity or transported to one of the onsite excess soil stockpile areas, Non-contaminated excess soils may be transported to onset excess soil stockpile areas, in accordance with Soil Relocation Guidance for SANGB (dated 2018-10-24) and Selfridge Design Standards (2017)

Elevated noise levels in the area will exist as worksite with in noise contours of aircraft.

C. Road crown shall run along length of road centerline and be sloped so that the water is shed to the grass and away from the apron.

D. Install (4) 10’ wide asphalt path comprised of the following:

i. Compacted subgrade, four passes
