3.3.1 General

Prior to the use or modification of Government-furnished upland disposal areas, submit a disposal area plan as specified in Paragraph "SUBMITTALS".

Conduct work in accordance with the approved plan; however, approval of the plan does not in any manner relieve the Contractor of his responsibility for the adequacy of the design and construction of the structures and drainage facilities required. The Government-furnished upland disposal area s approved for use under this Contract are Oldmans and Pedricktown North.

Take all necessary measures to ensure that the condition of the disposal areas, namely the dike, does not deteriorate or become damaged due to the pumping of dredged material into the site. Take every precaution to meet all of the requirements outlined in this specification in order to maintain the integrity of the disposal area. Immediately stop pumping into the disposal areas and contact the Contracting Officer if seepage on the exterior toe of the dike or other signs of imminent dike failure occurs.

3.3.2 Outfall Extension Work Plan

a. Install extensions to the four 30 inch sluice outfall pipes at the Oldmans Disposal Area, as shown on the drawings. Extend each outfall pipe such that the discharge end of the pipes are located within the mixing zone of the Delaware River (approximately 50 feet). Each pipe extension shall be secured to the respective sluice outfall pipe to prevent dislodging during pipeline flow and inclement weather.

b. The outfall point of the extension pipes shall be at the following New Jersey State Plain Zone 2900 coordinates:

Oldmans - E 229,860, N 346,710

c. The extension pipes shall be temporary and upon completion of the work, the materials shall be removed and become the property of the Contractor.

d. No excavation work will be required to perform this work.

3.3.3 General Requirements for Government-Furnished Upland Disposal Areas

a. Existing retaining dikes, sluices and drainage structures are available for use. Make all repairs, strengthening, extensions and modifications to such facilities as are necessary for confining the excavated material and for controlling disposal area effluent until acceptance of all work under the contract. Construct other structures or use other means necessary to control the dredge effluent as required to meet these specifications. Any work done in the disposal areas by the Contractor requires the prior approval of the Contracting Officer.

Section 35 20 23 Page 10

b. Maintain, repair and stabilize all dikes, roads and structures used under the contract, and inspect the dikes on a daily basis to assure their safety and stability. Restore all dikes, roads, structures and areas disturbed through work operations to a satisfactory condition as approved by the Contracting Officer, at no additional cost to the Government. The Government will have the right to regulate the use of the disposal areas throughout the contract. Do not disturb existing instrumentation and wells within the disposal area limits. Instrumentation or wells disturbed by the Contractor will be replaced by the Government at the Contractor's expense.

c. Contractor-furnished pipeline(s) shall enter the approved disposal areas only within the limits shown on the drawings. The Contracting Officer reserves the right to direct the extension of the Contractor-furnished pipeline beyond the discharge limits shown on the drawings, or to a specific location within the disposal areas, if required for efficient management of the disposal areas. Make provisions to prevent erosion of the dike embankment at the discharge point. Unless otherwise noted on the drawings, the end of the discharge pipe shall be located inside the disposal area limits at one of the following two distances measured normal to the dike centerline: 1) not less than 10 feet from the interior toe of the dike; or 2) not less than 50 feet from the interior crest of the dike;

whichever results in the longer pipe length. This length of pipe inside the disposal area shall be sufficiently and safely supported along the entire length by timber cribbing, a compacted earthen embankment or other means approved by the Contracting Officer. In addition, the pipe shall be angled in the horizontal plane such that the discharge does not scour the slope face or the toe-of-slope in the vicinity of the discharge area. The Government reserves the right to make the Government-furnished disposal area available for use by others when not in use as part of any work assignment under this contract. Obtain written permission from the Contracting Officer prior to entering on or utilizing any property owned or leased by the Government other than the diked disposal areas.

d. Construct a crushed aggregate ramp as shown on the drawings to protect the discharge pipe where it crosses the existing access road. Construct the access ramp to the width of the access road, and compact the aggregate around the discharge pipe.

3.3.3.1 Special Requirements for Government-Furnished Disposal Areas

a. Borrow for diking material may be obtained from within the disposal areas but not closer than 50 feet from the inside toe of the dike sections. Wet or dry borrow material as required to obtain optimum practical moisture content in accordance with ASTM D1556/D1556M. Borrow material and the ground surface upon which it is to be placed shall be free of all debris, timber and accumulations of vegetation. Place dike material in approximately equal layers not exceeding 12 inches in loose thickness and compact by the controlled traffic of spreading and/or hauling equipment over each layer. Borrowing of material from the area outside the existing perimeter dikes will not be permitted. Provide all impervious material required for mitigation of seepage problems during disposal operations from an approved off-site source if suitable material is unavailable from within the disposal area.

b. Any apparent seepage, stability, or safety problems shall be reported immediately to the Contracting Officer.

Section 35 20 23 Page 11

3.3.4 Additional Requirements for Government-Furnished Disposal Areas

a. Maintain a freeboard of two feet or more, measured vertically between the retained materials and water and the top of the adjacent confining dikes. If the required freeboard is not met, stop pumping into the disposal area until corrective means that are satisfactory to the Contracting Officer have been taken.

b. Pipe type weirs will not be permitted through exterior dikes, and the dredge pipe will not be permitted to enter the disposal area through an exterior dike. The hydraulic placing of perimeter dikes will not be permitted.

c. Perform modifications to the disposal areas that prevents obstruction of drainage on upland areas adjacent thereto, and to leave free, clear and unobstructed outfalls of sewers, drainage ditches, and other structures affected by the disposal operations. Distribute dredged material within the used portion of the disposal areas in a reasonably uniform manner that allows the disposal surface areas to drain after fill operations have ceased without creating excessive ponding on the fill surface.

d. Ensure that all sluices have structurally sound access walkways with handrails on both sides of the walkway from the dikes to the sluices throughout their length, and a walkway in a "T" formation along the front of the sluices to enable the inspector to readily obtain the samples of the mixture going over the discharge box interior weir as hereinafter specified. Timber used to construct the walkways and handrails shall be in accordance with the requirements for the sluice box timber and in accordance with Section 21 of EM 385-1-1.

e. Prior to pumping material into the disposal areas, inspect the existing fall protection by a qualified person as defined in EM 385-1-1. Remove existing systems not meeting this approval, and install a new system in accordance with EM 385-1-1. Submit the inspector's report of the existing system and design data for new systems. For bidding purposes, assume new fall protection systems are required.

f. Provide full body safety harnesses for employees and Government inspectors during the installation and removal of flashboards and the taking of samples from the effluent sampling location in the discharge box.

Each person working on the sluice shall wear a safety harness that is attached to the sluice framework using an appropriate approved device that conforms to EM 385-1-1 requirements.

g. Provide a minimum of 2 personnel at the disposal area when work (disposal or other) is being done at a disposal area. Provide a generator with a light plant sufficient to light the sluice area during darkness.

Provide radio communication between the disposal area personnel and the dredge at all times.

h. Perform routine inspections of the dikes prior to the start of dredging operations and at least twice a day during dredging operations. Conduct inspections along the entire perimeter of the disposal area, concentrating on the condition of the dike to ensure its integrity. If any signs of distress are noted during inspections, stop pumping the dredged material immediately and notify the appropriate Corps personnel. Typical signs of distress may include excessive seepage, fissures and slope failures.

i. Government Pipelines and Sluices: Government-owned submerged and shore

Section 35 20 23 Page 12 pipelines will not be available for use by the Contractor. If the Contractor uses the existing sluices for this work, he shall be responsible for their maintenance. Prior to dredging operations, perform the following:

(1) Inspect sluice boxes for damage and/or deteriorated flashboards and steel framework in the presence of the Contracting Officer. Realign or replace flashboards that are mis-aligned, damaged or deteriorated prior to deposition of dredged material into the facility, and repair deteriorated or damaged steel framework as directed by the Contracting Officer.

(2) Remove dirt, mud and debris from inside the sluice box.

(3) Weight the entire bottom of the inlet box with 12 inches of aggregate, as shown on the figure included at the end of this section.

(4) During dredging operations, if a flashboard(s) deteriorates and there is no viable disposal option, grafting of plywood to weakened sluice walls may be utilized as a temporary fix as directed by the Contracting Officer.
