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 stormwater control berm(s) as needed to control runoff. They are to be 3 feet high, with side slopes of 1V:2H, and should be constructed using existing, loose, and non-stockpiled material.

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 - 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, shall be steam cleaned of all debris (soil, dirt, plant parts, and vegetative matter) before being brought back to the site.

Limit mineral and Aggregate extraction, crushing, processing, and Equipment operation activities, including drilling and blasting activities, to the hours of half-hour before sunrise to 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:

For material source (Gap (M.P. 87) Quarry) (00235.01(a)) develop and maintain a bench access road from the developed processing area to the newly developed excavation floor as shown on the Plans. Construct this road with a width of 12 feet and reasonably uniform grade, no steeper than a 16 percent grade (1V:6H), for access to the quarry floor. An approximate location for development of this road is shown on the Plans. Determine the exact location in the field. Obtain the Engineer's approval in writing before constructing the access road.

For material source (Gap (M.P. 87) Quarry) (00235.01(a)) routine road maintenance activities such as grading and watering of the existing 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. Any expansion of existing access roads, including (but not limited to) maintenance activities that result in minor realignment and/or widening, must be reviewed and approved of by the Engineer in writing prior to being implemented.

For material source (Gap (M.P. 87) Quarry) (00235.01(a)) use loose shot material to construct a safety berm along the top edge of the new excavation 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) Overburden - Before excavating, including drilling and blasting when required, move all existing loose material from within the excavation area and the Proposed Bench Access Road location, and from areas immediately south, east, and west of the perimeter of the excavation area as shown on the Plans. Materials that meet quality requirements may be processed in accordance with the contract specifications or consolidated in the northwest corner of the quarry floor. Materials that do not meet quality requirements, such as reject fines, should be segregated and stockpiled with like materials as shown. Temporary stockpiles must be a minimum of 10 feet from the toe of the Aggregate stockpiles. Do not modify existing safety berms or perform any work outside of the designated Project Boundary as depicted on the Plans, including (but not limited to) staging, processing, or stockpiling. Existing loose material may be used to construct the safety berm around the excavation. Maintain a minimum 10‑foot buffer strip between the toe of the safety berm and the excavation area. Smooth and contour all constructed safety 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 (Gap (M.P. 87) 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, 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.

For material source (Gap (M.P. 87) 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.

Any existing loose material (including oversize) that must be moved or handled to facilitate implementation of the development plan and that meets quality requirements may be processed in accordance with the contract specifications. Existing loose materials that do not meet quality requirements, such as reject fines, must be segregated and stockpiled with like materials as shown.

For material source (Gap (M.P. 87) Quarry) (00235.01(a)) if the Contractor chooses to utilize this material source, maintain the condition of the existing access roads and gravel shoulder at the US20 MP 87.16 source entrance 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.

For material source (Gap (M.P. 87) Quarry) (00235.01(a)) maintain the wire livestock gate at the US20 MP 87.16 access road entrance 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/generated in the source by the Contractor that meets quality requirements, with the following exception:

For material source (Gap (M.P. 87) Quarry) (00235.01(a)), a maximum of 50 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 roads 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 new excavation area.

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

00235.46 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, crushing equipment 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.
