(b) USDA Forest Service Owned Sources - Material source Santiam (Little Nash) Cinder Pit (00235.01(a)) is under Agency control through a "Contract for the Sale of Mineral Materials" or a "Special Use Permit" agreement with USDA Forest Service.

Operations within this material source shall conform to the requirements of this agreement, the Plans, and the Specifications.

00235.42 Source Setup - Before proceeding with Work in the material source, the following apply:

(a) Access:

• For material source Santiam (Little Nash) (00235.01(a) routine road maintenance activities such as grading and watering of the access road do not need review or approval. Maintain or develop drain dips, water bars, road crowning, in-slopes and out-slopes during road maintenance.

• For material source Santiam (Little Nash) Cinder Pit (0235.01(a)) use overburden or existing, loose and non-stockpiled material or imported or clean soil or a combination of clean soil and rock, to construct a safety berm along the top edge of the new excavation or existing slopes as shown. Maintain a 10-foot buffer between the top edge of the excavation or slope and the toe of the safety berm. Construct the berm 3 feet high, with side slopes of 1V:2H.

(b) Clearing and Grubbing - Before stripping of overburden clear and grub all trees within the excavation area, to be developed for stockpile and processing and the area to be developed as access roads. Place all logs in the log decks and other woody debris in the slash disposal area as shown.

(c) Overburden - Before excavating, including drilling and blasting when required, strip and stockpile all soil overburden from within the excavation area, from the area to be developed for stockpile and processing, and from areas to be developed as access road(s). Incorporate grass and small shrubs into the stockpiles. Do not remove grass or small shrubs from the overburden. Place stockpiles in the overburden storage area(s).

Maintain a minimum 10-foot buffer strip between the toe of the overburden storage area(s) and the excavation area. Store overburden stripped from the stockpile and processing area as shown, a minimum of 10 feet from the toe of the Aggregate stockpiles. Smooth and contour overburden storage berms to form side Slopes no steeper than 1V:2H.

00235.44 Source Operations - The following apply during material source operations:

• Construct slopes, benches, and floor of the excavation area as shown.

• To control dust, apply water to material source access, haul road(s), and crushing and processing operations.

• For material source Santiam (Little Nash) Cinder Pit (00235.01(a) a water source is not available on-site within the material source. A possible water source is located at the ODOT Santiam Pass Maintenance Yard located approximately 1 mile east of the cinder pit at 13000 US20 Sisters, Oregon 97759.

• Stockpile reject fines in separate and accessible stockpiles as shown.

• For material source Santiam (Little Nash) Cinder Pit (00235.01(a) if the Contractor chooses to utilize this material source, maintain the condition of NF-820 at all times.

Provide traffic control related to ingress and egress movements in a manner that allows a safe work zone and safe passage of vehicles.

00235.45 Source Clean-up - The following apply at the completion of operations:

• Leave no loose material on the site exceeding 1 foot diameter, except as noted below.

Process existing oversize material, and all material loosened in the source by the Contractor that meets quality requirements, with the following exception(s):

• For material source Santiam (Little Nash) Cinder Pit (00235.01(a) a maximum of 100 cubic yards of oversize material with a maximum dimension of 2.5 feet may be stockpiled in the material source. Consolidate oversize material as shown.

• Place all excess produced Aggregate remaining at the end of operations in separate and accessible stockpiles on Agency owned or controlled property in areas designated by the Engineer, at no additional cost to the Agency.

• Leave the material source haul road and bench access road open. Do not rip or block the roads except a few boulders greater than approximately three feet in diameter may be used to block off access to the upper bench areas.

• Remove all loose, hanging or potentially dangerous Rock on or above the excavated surface.

• Pile and burn all construction slash and combustible debris resulting from use and development of the source, including the preexisting refuse identified at the pre-work meeting, even if it is from outside the material source project boundary except for grass and small shrubs that are incorporated into the overburden. Comply with all open burning regulations in effect at the time of source occupancy. If burning is not allowed, all construction slash and combustible debris become the property of the Contractor, to be treated as noncombustible and removed from material source.

00235.47 Source Vacating - Before vacating the material source the following apply:

• Remove all structures, noncombustible debris, and equipment from the material source, even if it was pre-existing, except for grass and small shrubs incorporated into the overburden.

• Remove solid waste and hazardous material from the site and dispose of properly.

These include, but are not limited to, bag-house sludge or fines, lime, excess liquid asphalt, rejected and excess asphalt mixture, plant cleanings, materials placed in sumps, tires, pipes, belts, screens and truck cleanings. Provide documentary evidence of proper disposal and verify the amount of material removed.

• If a spill or dumping has occurred or if a spill or dumping is suspected to have occurred, the Contractor shall clean up the contaminated materials according to Section 00290.

After clean up, the Engineer may, sample and test materials at the spill or dumping locations to verify the clean up has been completed. If the Engineer’s verification testing demonstrates remaining contamination, the Contractor shall perform additional clean up until the requirements of Section 00290 including 00290.20(g) are met.
