Do not conduct any operation on Sundays or legal holidays, as defined in ORS 279C.540.

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

(a) Access:

• For material source Identifier Quarry (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 Identifier Quarry (00235.01(a)) construct the bench access road as shown. Construct 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.

• For material source Identifier Quarry (00235.01(a)) use overburden to construct a safety berm along the top edge of the new excavation or existing slopes as shown and as needed. 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) 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. Utilize overburdern to construct safety berms as needed. Maintain a minimum 10-foot buffer strip between the safety berm 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.

For material source Identifier Quarry (00235.01(a)) restrict blasting to the hours of 9:00 a.m.

to 5:00 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 and floors 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 Identifier Quarry (00235.01(a)) a water source is not available on-site within the material source.

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

• For material source Identifier Quarry (00235.01(a)) if the Contractor chooses to utilize this material source, maintain the condition of the access road and US97 at the site access 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. Process existing oversize material, and all material loosened in the source by the Contractor that meets quality requirements, with the following exception(s):

• 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.

00235.46 Seeding:

• For material source Identifier Quarry (00235.01(a)) in addition to other areas with soil cover within the site disturbed by the Contractor's operations, stabilize the newly constructed safety berm, if needed, by seeding, mulching, and tackifying, as directed.

• For material source Identifier Quarry (00235.01(a)) provide the following seed mixture:

Broadcast Rate Common/Botanical Seed Name

7.7 lbs/acre Bluebunch Wheatgrass/Pseudoroegneria spicata

5.5 lbs/acre Idaho Fescue/Festuca idahoensis

3.3 lbs/acre Indian Ricegrass/Achnatherum hymenoides

3.3 lbs/acre Sandberg Bluegrass/Poa secunda

1.65 lbs/acre Bottlebrush Squirreltail/Elymus elymoides

0.55 lbs/acre Blue Flax/Linum lewisii

• Use only certified weed free seed. Provide copies of the certification to the Engineer.

Inoculate the clover and alfalfa prior to incorporation into the seed mixture.

• Provide 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 Engineer.

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

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