PIT DEVELOPMENT AND RESTORATION

The Contractor shall perform all clearing, grubbing, stump, and topsoil removal of the 300’ x 600’ logged area as necessary. This material shall be piled at the perimeter of the logged Barrett Pit area to act as barricades to entry to the pit area. Trees of merchantable value will have been removed by others prior to start of this contract. Under no circumstances shall the Contractor excavate banks that will cause standing trees to fall into the pit.

Dispose of all refuse and waste materials in accordance with existing Federal, State, and local laws. Keep and utilize the pit area in a manner that is safe to the public and the environment. Keep the work area clean and free of unnecessary clutter. Restore access routes and equipment travel ways to their pre-work condition; level the pit bottom. Final bank sloping will be restored to 3:1 or flatter.

FUEL STORAGE

The Contractor shall not locate any fuel storage tanks within the floor of the excavation or within 200 feet of any surface water. Fuel shall be stored in approved fuel tanks. Fuel storage tanks shall be either doubled walled or be located in a bermed area covered with two layers of 8-mil polyethylene film. The bermed area shall be sufficient in size to hold 1.5 times the volume contained within the storage tank. The polyethylene film shall be of sufficient size so that there are no seams below the secondary containment level. Clean water shall be pumped out within 24 hours of a rain event. The Contractor shall maintain the integrity of the secondary containment system for as long as fuel is stored on the site. The Contractor may submit other methods of providing secondary containment for review and approved by the Government. In no case shall the Contractor store on site more than 250 gallons of petroleum products or waste at any given time, excluding quantities contained in vehicles or other operating equipment.

The Contractor shall have onsite sufficient amount of fuel/oil absorbing material to absorb up to 25 gallons of spilled petroleum products. The Contractor shall have onsite the names and phone numbers of at least one contractor, who is qualified to respond and clean up fuel or other petroleum spills and maintains a 24-hour seven-day a week response service. These numbers shall be given to the Government at the pre-work meeting. The Contractor is responsible for the clean up of all spills to current MDNR-E and Forest Service standards.

HANDLING AND STOCKPILING AGGREGATE

The floor of each stockpile area will be leveled by the Contractor and surveyed by the Government prior to placing material. Construct stockpiles in layers up to 6’ maximum depth. Deposit aggregate material in such a manner as to prevent segregation (cone shape shall not be permitted where aggregate can run down long slopes). The stockpile shall be neat and regular in form and shall be made to occupy the smallest feasible area.

No track type of equipment will be allowed on the stockpiles. No remixing of the material is allowed by heavy equipment.

No independent sale of gravel to third parties is allowed without a gravel permit being issued by the Government.

MATERIALS

3-inch maximum size aggregate: The intention is to produce an aggregate with maximum size of 3-inches to be used as a road base. No gradation is specified, there is no requirement to add binder to the material. The Forest Service will analyze the material being produced, if it is determined that the material in the pit is not conductive to making an aggregate that will compact and support trucks the Contractor may be directed to add binder.

MEASUREMENT AND PAYMENT

The Government will measure the completed stockpile. Final payment quantity will be the total volume in cubic yards based on the Government’s measurements; however, the maximum amount will not exceed award amount. The final payment will not be adjusted for compaction in the completed stockpile. Method used to calculate the volume will be prismoidal or average end area method.
