Table 00235-1

00235.07 Source Development - If proposing changes to the material source development plan, submit a source development plan as an unstamped Working Drawing according to 00150.35. Do not begin Work in the material source until the source development plan has been approved in writing by the Engineer.

Develop a site-specific Erosion and Sediment Control Plan for the material source according to 00280.04 and submit it to the Engineer at or before the pre-work meeting. Construct/repair stormwater control berm(s) as needed to control runoff. Do not allow any materials, including sediments, Aggregate or crushing by‑products to enter into waterways or Wetlands.

Develop a site-specific Pollution Control Plan for the material source according to 00290.30(b) and submit it to the Engineer at or before the pre-work meeting. Include the following requirements in the Pollution Control Plan:

Do not discharge waste or by-product if it contains any substance in concentrations that could contaminate Soils or result in harm to fish, wildlife, or water sources.

Store all potentially hazardous materials and solid waste in a manner that prevents seepage into the ground or groundwater sources. Lined sumps or pits are allowable options for storage. If pits or sumps are used, construct adequate berms or provide other measures to prevent breaching of the pits or sumps.

For materials capable of causing water pollution if discharged, locate storage facilities in an area that prevents spillage into waterways or Wetlands.

Construction

00235.40 General - Steam clean all debris (soil, dirt, plant parts, and vegetative matter) from all vehicles and Equipment, prior to entering the site for the first time, and each subsequent time if the vehicle has left the Roadway outside the construction Project limits, before being brought back to the site. Notify the Engineer before moving each vehicle onto the site. Certify, in writing, that the Equipment has been steam cleaned.

00235.41 Restrictions and Protection of Resources - Comply with the following for all operations within the material source:

Protect cultural resources according to 00290.50.

Protect migratory birds according to 00290.36(a).

Clear trees and shrubs between September 1 and March 1. If operations within the source are to occur between March 2 and August 31, notify the Engineer 14 calendar days prior to source occupancy. The Engineer will arrange to have an ODOT biologist conduct a required nesting bird survey throughout the site to relocate nests if they are present.

Do not utilize, contaminate, or disperse material from existing stockpiles. If existing stockpiles interfere with the Contractor’s operations, move the stockpiles to other locations within the material source area as directed, at no additional cost to the Agency.

Limit mineral and Aggregate extraction, crushing, processing, and Equipment operation activities including drilling activities to the hours of one-half hour before sunrise to one-half hour after sunset, Monday through Saturday unless modifications to these hours are requested in writing and approved by the Engineer. 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:

Routine road maintenance activities such as grading and watering of the access roads do not need review or approval. Maintain or develop drain dips, water bars, road crowning, in-slopes and out-slopes during road maintenance.

Regrade 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.

Using existing, loose and non-stockpiled material or clean soil or a combination of clean soil and rock, construct or repair 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. Maintain a minimum 10‑foot wide buffer strip between the stormwater control berm material and the creek or cross culvert.

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.

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 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, bench, and floor of the excavation areas as shown.

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

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 US26 at the accesses 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 cattle guard 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 250 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 scalpings and/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.

00235.47 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 all solid waste and hazardous material from the site and dispose of properly. These include, but are not limited to, 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, 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, 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.
