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

(a) Access:

Realignment and/or widening of Egli Ridge Road is not allowed. No Project Manager’s approval to perform this Work will be given.

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. Material can be added to the road surface, but aggregate material is not allowed in the ditches.

Realign and/or regrade the bench access road as shown in Exhibit B. Reconstruct the road with a width of 12 feet and a reasonably uniform grade, no steeper than 50 percent (1V:2H), for access to the upper bench by tracked vehicles.

If needed, use existing, loose and non-stockpiled material or clean soil or a combination of clean soil and rock, construct a stormwater control berm(s). Grade and leave level, all areas of the material source disturbed during construction of the stormwater control berm(s). Construct the stormwater control berm 3 feet high, with side slopes of 1V:2H. After completion of the stormwater control berm, seed according to 00235.46.

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(s) 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 within the excavation area and any area to be developed as access road(s).

(c) Overburden - Before excavating, including drilling and blasting when required, strip and stockpile all soil overburden from within the excavation area 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. Smooth and contour overburden storage berms to form side Slopes no steeper than 1V:2H.

00235.43 Blasting - Perform blasting operations according to this Section and Section 00335, except that perimeter controlled blasting as described in 00335.40(a) is not required in the material source.

Restrict blasting to the hours of 7:00 a.m. to 6:00 p.m. Monday through Friday. Do not blast on Saturdays, Sundays, or legal holidays as defined in ORS 279C.540.

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

Construct slopes, bench, 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. Water from the reservoir adjacent to the site shall not be used.

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

If the Contractor chooses to utilize this material source, maintain the condition of US395 within 1,000 feet of the intersection with Egli Ridge Road 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.

Maintain the livestock gate into the source at all times.

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 all material loosened in the source by the Contractor that meets quality requirements, with the following exception:

· 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 in Exhibit B.

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 Project Manager, 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 berm or 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 work area 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.

00235.46 Seeding:

In addition to other areas with soil cover within the site disturbed by the Contractor's operations, stabilize the overburden storage areas, stormwater control berm(s), safety berms, and scalpings stockpile by seeding, mulching, and tackifying, as directed.

Furnish the following seed mixture:

Use only certified weed free seed. Provide copies of the certification to the Project Manager.

Furnish straw mulch according to 01030.15(b).

Apply a commercial straw mulch tackifier according to the manufacturer’s directions and at the recommended rate.

Apply seed and mulch according to Section 01030.

If conditions allow and the Contractor chooses, the area may be stabilized by applying seed using a range drill with a roller attachment. All areas seeded with the range drill and roller do not need to be subsequently covered with mulch and tackifier.

All variations to these requirements require written approval by the Project Manager.

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

Attend a post-work meeting at the material source to evaluate material source rehabilitation work with the Project Manager and attendees listed under 00235.05.
