Add the following:

At least 5 days prior to the preconstruction conference, designate in writing an Erosion Control Supervisor who is responsible for implementing the requirements of this Section. Do not designate the project superintendent as the Erosion Control Supervisor.

When temporary erosion control measures are required due to the Contractor's negligence, carelessness, or failure to install permanent controls as part of the work in a timely manner, provide temporary measures at no cost to the Government.

157.14 Acceptance. Add the following:

Soil erosion control will be evaluated under Subsection 106.02 based on the demonstrated ability of the erosion control measures to result in minimal soil erosion, sedimentation and/or siltation, and turbidity increases within or adjacent to the project limits.

Section 158. - WATERING FOR DUST CONTROL

Description

158.01 Add the following:

This work consists of furnishing and applying water to reestablish desert pavement soil crust.

Payment for watering for dust control on unpaved sections of the roadway will be limited to 7 days once finishing is completed.

Construction Requirements

158.03 General. Add the following:

Water will be available at no cost from a hydrant near the roadway at the Sunset Campground. The hydrant is located approximately 52 miles from the beginning of the project. The flow rate is approximately 300-500 gpm.

The water available at Sunset Campground can be used for other construction needs on this project. The water is available at no cost. The amount water allocated to this project is limited to 50,000 gallons per day. Install a meter and check valve (back flow prevention). Record the amount of water used. Submit a weekly report to the CO, which records the amount of water used.

In order to minimize disruption to the campers at Sunset Campground, the contractor will need to set up a stand tank in the special use area which is on the North side of the overflow camping area. This will require approximately 1000’ of temporary above ground water line to run from the hydrant to the stand tank.

Perform watering to reestablish desert pavement soil crust in a manner that avoids runoff scars as directed by the CO. This may require slower operating speeds and lower volumes of water dispersed from the water truck during operation.
