  2. Utility Disconnections. Before demolishing any building, arrange to disconnect and terminate all utilities and facilities that are connected to the building, as specified by the municipalities and companies owning or controlling them.

    If only a portion of an occupied structure is to be demolished, conduct demolition and related operations so that service is not interrupted to the portion of the structure that is not demolished. Where it is necessary to reconnect any facilities to the undemolished portion of the structure, make reconnections permanent.

    Notify, in writing, the municipalities and companies concerned when such disconnections, terminations, or reconnections are required and provide copy to RE. Perform this work according to the municipalities and companies standard practices and requirements and under their supervision; otherwise arrange for the work to be performed with their forces.

  3. Rodent Control and Extermination. Before beginning demolition operations, retain a qualified sanitation inspector to conduct a survey for evidence of current rodent activity. Initiate a control program by a certified pest control operator if the survey indicates that it is necessary.

    Apply exterminating materials according to N.J.A.C 7:30, et seq.

    At least 10 days before beginning demolition of any structures, the pest control operator shall begin ridding the structure and adjacent areas within the Project Limits of rodents or their carcasses and to prevent their migration to other adjacent areas.

    Where there is no competing water supply, the Contractor may use liquid anticoagulant baits at the discretion of the certified pesticide applicator.

    Place toxic bait in the form of a 1-pound paraffinized block in each manhole or inlet of storm or combination drains located on the same street as the building to be demolished and within the same block, including the entire intersections of the nearest cross streets. Place bait in suitable locations within the drainage structures, as determined by the pest control operator. Fasten the bait block in its location with wire.

    Inspect and renew toxic bait in structures or drains as necessary after initial baiting.

    Remove and dispose of carcasses to the satisfaction of the RE.

    After the initial treatment and each follow-up inspection, submit a signed statement, from the pest control operator, reporting the amount and type of bait placed in each location and stating the visible results obtained from the rodent control program.

    Ensure that the pest control operator is aware of the antidote noted on the rodenticide label.

  4. Demolition Operations. Before demolishing buildings, remove and dispose of chemicals, miscellaneous cylinders, drums, above ground and underground heating oil tanks, asbestos, and garbage from the building according to applicable Federal, State, and local laws, rules, and regulations. Remove and recycle materials that are required to be recycled by the Federal, State, and local laws, rules, and regulations. Before beginning demolition operations, pump out and clean basements, wells, cesspools, and outbuildings within the areas to be cleared in a sanitary manner. After being disinfected as required by the health authorities, backfill to adjacent ground level as specified in 201.03.07.5.

    Maintain wells, cisterns, cesspools, and other openings in the ground outside the area to be cleared without hindering their functionality. Cap well casings securely and permanently as specified in 201.03.06, and cut off and cap pipes leading into or out of the well.

    Leave adjacent buildings in a safe condition, and do not deface, mar, or jeopardize them in any way. Repair or restore damaged buildings to the satisfaction of the RE.

    Ensure that the phases of demolition are performed within the designated limits and without hazard to adjacent properties or to the public. Do not set any structure on fire.

    Do not demolish or disturb chimneys common to adjacent properties other than to give them the necessary support for their continued stability. If necessary, repoint and cap them.

    When demolishing a portion of a building, shore, brace, and support the remaining part so that the integrity and support of all remaining walls, floors, roofs, and their supporting members are maintained and continued in such a way that shoring, bracing, and support is outside the ROW. Board up and seal the remaining portion of such a partially demolished building along the ROW, and weatherproof the new closure and its connections to the remaining portion of the severed building. Material for closure shall consist of adequately braced studding of 2 x 4-inch timbers placed no more than 16 inches on center with wood facing, or equal, nailed to the studding and without any holes appearing therein. Cover the wood facing with 2 layers of smooth-finished, 65 pounds per roll, roofing material according to ASTM D 224 and having an overlap of at least 4 inches.

  5. Backfilling. Backfill and compact subsurface areas including cellars using the directed method as specified in 203.03.02.C. The RE may require compaction using the density control method as specified in 203.03.02.D. Use all available excavated material from within the Project Limits before bringing additional material for backfill to the Project Limits. If sufficient material is not available, backfill with I-14 soil aggregate. If excavated material or I-14 soil aggregate are recycled material, place the recycled material at least 2 foot above the water table.

    Ensure backfilling and grading establishes proper drainage. Before placing the first lift, break existing cellar floors and other surfaced areas into pieces having areas of less than 4 square feet with well-defined cracks through the full depth of the floors, or make holes of more than 1 square foot area through the floors on approximately 10-foot centers to provide vertical drainage. Remove wooden cellar floors.

    Clean, point, and apply 2 coats of waterproofing material to party wall foundations before backfilling against. If necessary, grade around the ground surface to eliminate water pockets.

    Backfill and level cellars and all other subsurface spaces to the adjacent ground elevation.

201.03.08 Asbestos Removal

202.03.01 Stripping

Before beginning the operations, obtain the RE's approval for stripping operations scheduled between November 15 and March 1. The RE will base approval on the Contractor's alternate method for stabilizing disturbed areas when seeding is not feasible due to seasonal constraints.

Strip vegetation and underlying soil to a depth of 4 to 6 inches below the existing ground surface. Confirm the thickness of stripping with the RE based on field conditions. Temporarily store in stockpiles, as specified in 202.03.03.B, stripped material including excess that is determined suitable for the future use of the Department. The Department will sample and analyze stripped material in stockpiles to determine suitability for use as topsoil. Store suitable stripped material within the Project Limits until placement. Reuse or dispose of unsuitable stripped material as specified in 202.03.07.

202.03.02 Excavating Test Pits

Before beginning Construction Operations, locate existing subsurface structures and utilities that may be affected by or interfere with the proposed construction. Obtain utility locations as specified in 105.07. If directed by the RE, excavate to obtain the utility location.

Excavate as specified in 202.03.03 and as directed by the RE. Excavate test pits or portions of a test pit by hand when in close proximity to utilities or when directed. Backfill test pits with excavated material in 6-inch lifts, and compact using the directed method as specified in 203.03.02.C.

202.03.03 Excavating Unclassified Material

  1. Excavating. The Department, as the generator, is solely responsible for the designation of excavated material. Unclassified excavation consists of excavation and management of material of whatever nature encountered, except for regulated material, pavement removal and acid producing soil.

    Excavate using equipment and methods that remove material to the specified excavation limits without disturbing the material outside of the excavation limits. While excavating, protect facilities and structures from damage and disturbance. Ensure that material outside excavation limits is not disturbed. If any material outside the excavation limits becomes disturbed, restore the area as directed by the RE. Excavate and grade to ensure proper drainage.

    Do not excavate more than 15 feet in depth without stabilizing the slope either by temporarily seeding and mulching, or by topsoiling, permanently seeding, and mulching as specified in 806.03.01. Submit alternate methods for stabilizing slopes when seeding is not allowable due to seasonable constraints. Obtain RE approval of alternate methods before beginning embankment construction. Repair damaged seeded areas as specified in 806.03.01.

    Notify the RE if excavation to the finished grade section results in unstable subgrade or slopes. Obtain RE approval before removing unstable material and backfilling the area with suitable material. Backfill with excavated material and compact using the directed method as specified in 203.03.02.C.

    If a slope failure develops during excavation, immediately cease operations. Determine the limits of unstable material, and start backfilling immediately. Once the slope has been stabilized, resume excavation by RE approved methods.

    The RE will check elevations of the roadbed subgrade as specified in 202.03.03.C. Ensure that the elevation is within ±1/2 inch of the specified elevation.

    Use excavated material on the Project, as directed by the RE, or as specified in 202.03.07.

    1. Wet Areas. If required, submit a dewatering plan including method of dewatering and controlling sediment and contaminants from entering adjacent waterbodies, wetlands, and environmentally sensitive areas. Obtain RE approval for dewatering operations before beginning the work. Excavate wet areas down to firm bottom within the lateral limits. Test the bottom of the excavation area at frequent intervals as the excavation progresses, by taking soundings, samples, or other tests, to determine when firm bottom is reached. The Department may require the Contractor to take additional borings or samples to determine if unsuitable material remains or is entrapped within the excavation limits.

      Excavate using equipment and methods \to the specified elevation without disturbing the material below that elevation. If the methods and equipment disturb the material below the specified elevation, immediately stop operations. Resume excavation using alternate methods and equipment as approved by the RE.

      The RE may allow the use of dikes, well points, or other means for dewatering the excavation areas if cofferdams are not shown on the Plans. If permits are required for this work, submit a copy of approvals, as specified in 107.01.02, to the RE before proceeding with the work.

    2. Foundation and Bridge Areas. Excavate for footings to the limits shown in the plans causing minimal disturbance to the remaining embankment. If the underlying material is disturbed, compact it using the directed method as specified in 203.03.02.C. Backfill and compact the remaining excavated area using the density control method as specified in 203.03.02.D. Restore the embankment to the final section.

      Remove boulders or rock fingers projecting into the bottom of the excavation to a minimum depth of 6 inches below the bottom of footing. Backfill the space with coarse aggregate, and compact it using the directed method as specified in 203.03.02.C.

      In areas where the footing rests partly on soil and partly on rock, excavate the rock to 2 feet below the footing. Backfill the space with coarse aggregate, and compact it using the directed method as specified in 203.03.02.C.

      In areas where the footing rests entirely on rock, excavate to a firm, level, roughened surface. Clean out seams, and fill them with concrete or mortar before placing concrete for foundations.vIf shale is encountered at the bottom of the footing and the footing is not poured the same day, leaving the shale exposed to air or water, undercut the shale at least 4 inches. Seal the undercut with the same class of concrete as the overlying footing to the bottom of the footing elevation, and provide a rough finish.

      If during the course of the excavation, rock is shattered below the foundation elevation, remove the shattered rock and fill the void with the same class of concrete as the overlying footing.

      The RE may order, in writing, changes in dimensions or elevation of footings as necessary to secure an acceptable foundation.

      After completing the excavation to the elevation of the bottom of the footing, obtain the RE's approval before beginning footing construction or placement of coarse aggregate.

      When specified, place coarse aggregate following the completion of the excavation. Shape the material on which the coarse aggregate is to be placed to an even surface. Place coarse aggregate in 6-inch lifts and compact using the directed method as specified in 203.03.02.C.

    3. Rock Areas. The Contractor may remove entire boulders extending beyond the specified limits of excavation. Backfill and compact space created outside the specified limits by such boulder removal using the directed method as specified in 203.03.02.C. Ensure that undrained pockets are not left in the surface of the rock.

      After completing the excavation of each lift of rock slope construction and before beginning the next lift, scale the completed slopes to remove loose rock fragments. The RE will examine rock slopes during the excavation to identify possible unstable conditions and to determine the need for stabilization. Provide assistance and equipment necessary for such examination.

      If it is determined that in-place stabilization is required, use rock bolting or other stabilization techniques as directed. Before drilling and blasting, remove existing overburden to the top of rock. Take necessary precautions in drilling and blasting operations to preserve the rock remaining in the specified finished slope in a natural undamaged condition. Conduct blasting operations according to the following:

      1. Blasting Plan. Submit a blasting plan at least 14 days before commencing drilling and blasting operations and before each subsequent shot thereafter. Include the full details of the drilling and blasting patterns and controls to be used for both the presplitting and production blasting. Additionally, include the following minimum information:

        1. Station limits of proposed shot.
        2. Plan and section views of proposed drill pattern, including free face, burden, blasthole spacing, diameters and angles, lift height, and subdrill depth.
        3. Loading diagram showing type and amount of explosives, primers, initiators, and location and depth of stemming.
        4. Manufacturers' data sheets for explosives, primers, and initiators to be employed.
        5. Initiation sequence of blastholes including delay times and delay system.
        6. Planned security measures for storage of explosives.
        7. Safety plan for personnel and public.
        8. Copy of blasting license.
        9. Name and qualifications of blasting supervisor.

        The blasting plan submittal is for quality control and record keeping purposes. A review of the blasting plan does not relieve responsibility for the accuracy and adequacy of the plan when implemented in the field.

      2. Blasting Test Sections. Before commencing full-scale blasting operations, demonstrate the adequacy of the proposed blasting plan by drilling, blasting, and excavating short test sections, up to 100 feet in length, to determine which combination of method, hole spacing, and charge works best. The RE may direct additional test sections when field conditions warrant.

        Conform to the requirements for controlled and production blasting operations when blasting in conjunction with the test shots.

        Do not drill ahead of the test shot area until the test section has been excavated and the results evaluated. If the results of the test shots are unsatisfactory, revise methods to achieve the required results. Unsatisfactory test shot results include an excessive amount of fragmentation beyond the shown lines and grade, excessive flyrock, or violation of other requirements.

        If, at any time during the progress of the work, the methods of drilling and blasting do not produce the desired result of a uniform slope and shear face, within the tolerances specified, drill, blast, and excavate in short sections, not exceeding 100 feet long, until a technique is arrived at that produces the desired results.

      3. Safety. Handle explosive materials and conduct blasting operations as specified in 105.10. Use only standard explosives, blasting agents, detonating cord, delays, blasting caps, and other blasting accessories prepared and packaged by explosive manufacturing firms.

        Restrict access to the entire blast area for a minimum of 5 minutes following a blast to guard against rock fall before commencing work in the cut.

        The RE will prohibit or halt the blasting operations if it is apparent that through the methods being employed, the required slopes are not being obtained in a stable condition, or the safety and convenience of the traveling public is being jeopardized.

      4. Methods of Drilling and Blasting.

        1. Presplitting. Presplitting is a controlled blasting method for constructing a shear plane along a specified cut slope through the controlled use of explosives and accessories in properly aligned and spaced drill holes.

          After removing the overburden and weathered rock, drill slope holes for presplitting along the line and in the plane of the cut slope. Drill slope holes between 2-1/2 and 3 inches in diameter. Control operations to ensure that the drill holes do not deviate from the plane of the slope by more than 6 inches and do not deviate within the plane of the slope by more than 6 inches.

          Ensure that the drilling equipment for drilling the presplit holes has mechanical devices affixed to accurately determine the angle at which the drill steel enters the rock. The RE will not allow presplit hole drilling if these devices are either missing or inoperative. Do not space slope holes more than 3 feet on centers, and adjust spacing as required to produce a uniform and stable shear plane between slope holes. Under certain conditions, to produce a uniform and stable shear plane, the RE may also require auxiliary holes, which are identical to the slope holes but are not loaded with explosives.

          The Contractor may extend the length of the slope holes to the full depth of the cut, to a maximum of 50 feet, if hole alignment is maintained. Otherwise, drill and blast slope holes in lifts. If presplitting in lifts, the RE will allow a maximum offset of 6 inches to accommodate the drill head. Arrange lifts so that the toe of the finished cut slope coincides with the toe of slope. Before placing explosives or blasting agents, ensure that the hole is free of obstructions for its entire depth.

          Provide explosives for use in presplit holes with a maximum diameter less than 1/2 the diameter of the presplit hole, and ensure that explosives do not touch the side of the hole. Use only standard explosives manufactured especially for presplitting in presplit holes, unless otherwise approved. Do not load bulk ammonium nitrate and fuel oil in the presplit holes.

          Use an amount of explosives in the presplit hole that produces the shearing without causing overbreak. Ensure that the top of the load is far enough below the collar to avoid overbreak at the surface. Extend the detonator cord downline from the collar to the bottom of the bore hole and from the collar to the detonator trunkline or electric blasting caps. Prime the explosive charge according to the recommendations of the manufacturer of the commercial explosive or blasting agent.

          If using fractional portions of standard explosive cartridges, firmly affix them to the detonating cord so that the cartridges do not slip down the detonating cord or bridge across the hole. Do not space fractional cartridges along the length of the detonating cord farther than 30 inches on center. Adjust spacing to give the desired results.

          Assemble continuous column cartridge type of explosives used with detonating cord, and affix them to the detonating cord according to the explosive manufacturer's recommendations. Provide a copy of these instructions to the RE.

          The Contractor may make the bottom charge of a presplit hole larger than the line charges but not so large as to cause overbreak. Place the top charge of the presplitting hole far enough below the collar, and reduce the charge sufficiently, to avoid overbreaking and heaving.

          Stem the upper portion of presplit holes, from the topmost charge to the hole collar. Stemming materials shall consist of drill cutting or 3/8-inch clean stone chips.

          The Contractor does not need to stem below the topmost charge unless the Department determines that the rock is very seamy and incompetent, in which case, the Contractor may need to full stem such zones.

          The Contractor may detonate presplit holes instantaneously or on short delays between each hole. Ensure that delay detonating does not exceed 25 milliseconds between holes. Detonate presplit holes before detonating any production holes.

          Extend presplitting a minimum of 50 feet ahead of the production blasting limits, but not more than 100 feet beyond the exposed presplit face.

        2. Production Blasting. Production blasting is a method of drilling and blasting to produce a high degree of fragmentation of the rock mass to be excavated.

          Drill the adjacent line of production holes inside the presplit lines so as to avoid damage to the presplit face. If necessary, the Contractor may drill the first line of production holes parallel to the presplit face to reduce overbreak of this face.

          The Contractor may vary hole diameter, spacing, delay patterns, explosives, blasting agents, and other variables to obtain a fragmentation acceptable to the RE, provided that the existing presplit face is not damaged.

  2. Temporarily Storing. Temporarily store soil in stockpiles in well-drained areas no closer than 50 feet from streams, wetlands, floodplains, other waterbodies, and as shown on the Plans. Construct stockpiles on polyethylene sheeting. Overlap joints in the underlying polyethylene sheeting a minimum of 12 inches. Contain stockpiles with haybales or silt fence placed continuously at the perimeter of the stockpiles. Construct stockpiles to heights not exceeding 15 feet and with side slopes no steeper than 2H:1V. Segregate material of differing types and levels of contamination depending on reuse or disposal.

    Protect and maintain the stockpile and embankment until reuse or disposal. Provide protection for the stockpile to control the stormwater run-off, erosion, and unauthorized contact. Where the material in the stockpile is saturated, pitch the bottom polyethylene sheeting towards a discharge basin to collect water drained from the stockpile. Manage the collected water in the same manner as that generated during dewatering operations.

    Maintain the polyethylene sheeting or replace it as needed for as long as the stockpile remains. Periodically inspect stockpiles to ensure that material is not released into the surrounding environment.

    When temporarily storing soil is not possible within the Project Limits, the Contractor may temporarily store soil at a site provided by the Contractor outside the Project Limits as approved by the RE and meeting the requirements of 105.08 and 108.04.

    If the stockpile remains exposed for more than 15 days, temporarily seed, as specified in 806.03.01, and mulch stockpiles as specified in 809.03.01 or 809.03.02.

    When the stockpile is removed, restore the area to the original condition.

  3. Measuring Elevation. Using Contractor established grade stakes set outside the pavement box and at breaklines, the RE will check elevations within the roadbed limits using a stringline drawn taut between these stakes. Ensure that grade stakes indicate the vertical cut or fill measurement referenced to the finish grade. The RE will check elevations longitudinally every 50 feet and transversely at the edges, breaklines, and the center of each lane and shoulder. The RE may direct additional grade stakes in areas with rapid changes in grade so that intermediate longitudinal checks can be made.

202.03.04 Excavating Regulated Material

The Department, as the generator, is solely responsible for the designation of excavated material. Regulated material excavation consists of excavation and management of material of whatever nature encountered that is classified as regulated or hazardous in the NJDEP Solid Waste Regulations, N.J.A.C 7:26-1 et seq. or N.J.A.C 7:26-8.

In the PPC log, note daily water removal, treatment and discharge volumes, effluent sampling activities and results, discharge or spill incidents, and sampling and reporting activities.

202.03.05 Excavating Acid Producing Soil (APS)

The Department, as the generator, is solely responsible for the designation of excavated material. Acid producing soil (APS) excavation consists of excavation and management of high acid producing soil, with a pH below 4.0 or soil containing iron sulfides. Areas of known APS are shown on the Plans. Dispose of APS as specified in 202.03.07.B.

  1. Pre-Excavation Plans. Submit a Materials Handling Plan as specified in 202.03.04.1.

  2. Excavating. Excavate APS material as specified in 202.03.03 and as shown on the Plans.

  3. Temporarily Storing. Temporarily store APS in separate stockpiles as specified in 202.03.03.B within the Project Limits and as shown on the Plans. Construct stockpiles on polyethylene sheeting. Contain stockpiles using silt fence, haybales, or other non-vegetative erosion control features to limit movement of soil and possible acidic runoff. Cover stockpiles with polyethylene sheeting. Secure and maintain cover in place. Overlap joints in the polyethylene sheeting a minimum of 12 inches, and place securing materials along the joints. Maintain the cover, and replace damaged polyethylene sheeting as needed. Ensure that no stockpile is left uncovered and exposed to the air or precipitation for more than 8 hours to minimize oxidation

    Clean equipment used for the movement of APS at the end of each working day and before removing it from the Project Limits to prevent spreading of APS to other areas within the Project Limits and to prevent tracking APS off-site. Install non-vegetative erosion control features around the equipment cleaning area to limit the movement of the APS and possible acidic runoff. Temporarily store the APS from equipment cleaning in the APS stockpile.

  4. Sampling and Analysis. Test stockpiled soil at a NJDEP certified laboratory for APS according to the NJDEP Technical Manual for Stream Encroachment. Within 10 days of stockpiling, submit 3 copies of the results to the RE.

  5. Acid Soil Remediation. When reusing excavated APS as backfill or embankment in areas to be vegetated, place APS at the bottom. Remediate the soil by covering the APS with a layer of pulverized limestone applied at a rate of 6 tons per acre (or 275 pounds per 1000 square feet) of surface area, and as follows:

    1. Where establishing turf, cover the limestone layer with a minimum of 12 inches of compacted soil with a pH of 5 or more.
    2. Where planting trees or shrubs, cover the limestone layer with a minimum of 24 inches of compacted soil with a pH of 5 or more.
    3. Do not place APS within 24 inches of a slope or bank surface (such as berms, stream banks, ditches, etc.) or structure to prevent potential lateral leaching.

    Immediately following remediation, place topsoil, fertilizer, seed, and mulch over APS not under pavement for permanent erosion control. Dispose of excess APS as specified in 202.03.07.B.

  6. Document Control. Perform document control as specified in 202.03.04.5, except that PPC logs are not required.

202.03.06 Removing Pavement

Before removing HMA, concrete, or composite pavement, wet sawcut. Wet sawcut joint areas and overlying HMA courses full depth parallel to the centerline of the joint for the width designated. Use a saw capable of providing a neat cut for the full depth in a single pass.

Do not use equipment that involves a ball, weight, or punch to break or remove the concrete within 5 feet of a transverse joint or within 3 feet of any structure or pavement that is to remain in place. Break up or remove the concrete within restricted areas so as not to damage the adjacent joint structure, pavement, or other structure that is to remain.

Contain debris from the breaking of concrete base and concrete surface courses within the work site. Use necessary containment devices to protect adjacent vehicular or pedestrian traffic from flying debris. Reuse or dispose of material as specified in 202.03.07.

202.03.07 Reuse or Disposal of Excess Material

  1. Reuse. Before using other excess materials, reuse regulated material as shown on the Plans or with RE approval.

    The Contractor may use excavated material, if the requirements specified in 901.11 are met, to construct Items requiring soil aggregates. Submit written notification at least 15 days before reuse.

    Upon RE’s approval, reuse excavated soil to widen or flatten slopes of embankment, to fade embankments into cuts, or as approved at other locations. Ensure that the excess material is not reused within a wetland, a transition area, a riparian zone, a flood hazard area or other regulated area without obtaining an appropriate NJDEP permit.

    The Contractor may reuse broken concrete, HMA pieces, and millings in the lower portion of I-14 soil aggregate. Spread out pieces in layers, with the pieces lying flat and not arching, with spaces between the pieces filled with soil. Use pieces with a maximum individual size of 2 cubic feet, with a 2-foot maximum dimension on any side. Do not place the broken concrete, HMA pieces and milling within 2 feet of the final subgrade, less than 2 feet above the highest seasonal high ground water table or within 2 feet of any underground utility. Compact material using the directed method as specified in 203.03.02.C.

    Dispose of excavated material that will not be reused as specified in 202.03.07.B.

  2. Disposal. Dispose of excess regulated material as specified in 202.03.08. Dispose of excess APS at approved landfills according to applicable Federal, State, and local laws, rules, and regulations. For excavation not designated as regulated material or APS, provide the following before removing the excess excavation from the Project Limits.

    1. At least 10 days before disposing, submit the disposal procedure and location to the RE for approval. Do not dispose of excavation on property proposed to be or used for parks, playgrounds, and other recreational purposes; residential facilities; educational facilities; environmentally sensitive areas such as wetlands; historic sites; or within sight of a State highway during all seasons.
    2. Obtain the potential owner's notarized authorization of the acceptance of the excess material. If the potential owner requires environmental material sampling, obtain RE’s approval at least 7 days before sampling for oversight only. Approval of the sampling does not imply agreement with the sampling results and the Department reserves the right to sample the material for classification. Provide the RE all testing results and documentation associated with the sampling.
    3. Load and transport excess material that the RE determines to be excess, unusable or unsuitable for the project according to Federal, State, and local law, rules and regulations.

    Once material leaves the Project Limits, the Contractor is responsible for ensuring that the handling procedures, placement method, and disposal location are according to applicable Federal, State, and local laws, rules, and requirements, including permits that may be issued for the Project. If the disposal of excess material results in a violation notice from any governmental authority, immediately correct the violation. Indemnify and defend the Department for any violation incurred, penalty assessed, or any claims, suits, losses, demands or damages of whatever kind or nature arising out of, or claimed to arise out of, the improper disposal of excess materials.

    If the Contractor does not correct the violation to the satisfaction of the governmental authority that issued the violation notice, the Contractor is responsible for assessed penalties including costs incurred by the Department to remedy the violations.

    Dispose of other material or debris as specified in 201.03.09.

202.03.08 Disposal of Regulated Material

Load, transport, and dispose of regulated material that the RE determines to be excess, unusable, or unsuitable for the Project according to Federal, State, and local laws, rules, and regulations and as specified in 202.03.07.B. Pay fees associated with removal and disposal of regulated materials.

Submit the results of material sampling and analysis, waste facility applications and acceptance documentation, and fee payment requirements to the RE at least 15 days before planned removal of regulated material. Submit to the RE a bill of lading for each truckload of regulated material removed from the Project Limits. Ensure that the bill of lading and waste manifest include the following information:

  1. Transport subcontractor name, address, permit number, and telephone number.
  2. Type and quantity of material removed.
  3. Weight of vehicle with weigh slip.
  4. Recycling or disposal facility name, address, permit number, and telephone number.
  5. Date removed from the Project Limits.
  6. Signature of transport vehicle operator.

The RE will sign the bills of lading for the Department as the generator of the Project Limits. Submit 1 copy of the bill of lading to the RE by the end of each working day that the transport vehicle leaves the site.

The licensed hauler shall transport the regulated material to the disposal/recycling facility with no unauthorized stops in between, except as required by regulatory authority. The hauler shall use appropriate vehicles and operating practices to prevent spillage or leakage from occurring during transport. Remove excess soil adhering to the wheels or under carriage of the vehicles before leaving the Project Limits. If soil or water escapes to the public roads, immediately clean the road to restore it to the original condition and immediately notify the RE. Do not transport regulated material over public roads if they contain free liquid or are sufficiently wet to be potentially flowable during transport.

Submit 1 copy of the documentation of the disposal facility's acceptance of the regulated material, including the weight ticket slips, to the RE and the county of origin within 15 days of acceptance at the disposal facility.

Immediately submit written notification to the RE if problems arise, regarding the facility chosen to accept the regulated material for off-site management, that would require the return of waste, or if the chosen facility has violated any environmental regulation that may result in regulatory enforcement action. Propose an alternate disposal facility, and obtain the RE's written approval of off-site management at such facility.

202.03.09 Disposal of Regulated Material, Hazardous

Submit the results of material sampling and analysis, waste facility applications and acceptance documentation, and fee payment requirements to the RE at least 15 days before planned removal of hazardous regulated material. For each truckload of hazardous regulated material removed from the Project Limits, submit to the RE a bill of lading and waste manifest that include the following information:

  1. Transport subcontractor name, address, EPA ID number, and telephone number.
  2. Type and quantity of material removed.
  3. Weight of vehicle with weigh slip.
  4. Recycling or disposal facility name, address, permit number, and telephone number.
  5. Date removed from the Project Limits.
  6. Signature of transport vehicle operator.
  7. Waste manifest tracking number.

The RE will sign the manifest as the generator and will forward questions or concerns to the Bureau of Environmental Program Resources for resolution. The manifest will verify the type and quantity of hazardous regulated material being transported off-site.

The Uniform Hazardous Waste Manifests are required by the Federal Resource Conservation and Recovery Act (RCRA) (40 CFR Subpart B Parts 262.20 to 262.23) and N.J.A.C 7:26G for all off-site shipments of hazardous regulated materials. The Department is the generator of the waste. The Department will obtain an EPA Identification Number (EPA ID#) and supply this information to the RE for inclusion on the Uniform Hazardous Waste Manifest. The RE will provide the Contractor with an EPA ID# if the Project contains hazardous regulated material.

Complete the manifest form in accordance with all applicable regulations and mail to the Bureau of Environmental Program Resources at 951 Parkway Avenue, PO Box 600, Trenton, NJ 08625-0600 to ensure that the “final disposition” (TSD to Generator) copy of the manifest is mailed back to the office responsible for the record keeping requirements.

The RE will keep a copy of the original manifest for the Contract files. The Bureau of Environmental Program Resources will distribute the original manifests in accordance with the regulations and also for retention of the manifests per regulatory requirements.

The Contractor is responsible for all manifest discrepancies. Immediately report discrepancies to the RE and resolve to the satisfaction of the RE. The RE will forward a copy of manifest discrepancy letters to the Bureau of Environmental Program Resources.

The licensed hauler shall transport the hazardous regulated material to the disposal/recycling facility with no unauthorized stops in between, except as required by regulatory authority. The hauler shall use appropriate vehicles and operating practices to prevent spillage or leakage from occurring during transport. Remove excess soil adhering to the wheels or under carriage of the vehicles before leaving the Project Limits. If soil or water escapes to the public roads, immediately clean the road to restore it to the original condition and immediately notify the RE. Do not transport hazardous regulated material over public roads if they contain free liquid or are sufficiently wet to be potentially flowable during transport.

Submit 1 copy of the documentation of the disposal facility's acceptance of the hazardous regulated material, including the weight ticket slips, to the RE and the county of origin within 15 days of acceptance at the disposal facility.

Immediately submit written notification to the RE if problems arise, regarding the facility chosen to accept the hazardous regulated material for off-site management, that would require the return of waste, or if the chosen facility has violated any environmental regulation that may result in regulatory enforcement action. Propose an alternate disposal facility, and obtain the RE's written approval of off-site management at such facility.

203.03.01 Constructing Embankment

Before beginning embankment, excavate and stabilize side ditches, and install perimeter SESC measures as specified in 158.03.02. Ensure that the ground surface is not frozen and is free from snow, ice, and mud before constructing embankment.

Do not backfill or begin constructing embankment against a structure until the forms can be removed as specified in 504.03.02.G. Where existing pipes and conduit have insufficient soil cover during embankment construction, protect the pipes and conduit from damage by the equipment and operations.

Backfill and compact low areas, holes, channels, and ditches using the directed method, as specified in 203.03.02.C, before constructing embankment.

Before placing embankment or any other unbound aggregate material, such as subbase or dense graded aggregate, on existing pavement, break the pavement into pieces that are a maximum of 12 inches in all dimensions.

When constructing an embankment against an existing slope or when constructing an embankment in stages, bench the existing slope against which the embankment is to be placed as the embankment is constructed in lifts. For each lift, bench a minimum of 6 feet into the existing slope to allow the new embankment to integrate with the existing slope. Compact benched areas with the new embankment.

If the RE determines that the moisture content of the existing ground, previously constructed embankment, or embankment material may adversely affect embankment construction, cease embankment construction until the moisture content is corrected.

Construct embankment to ensure adequate surface drainage is provided at all times. Construct the center of the roadbed higher than the sides, and keep the surface uniformly graded and compacted. At the end of each working day, construct temporary stabilized berms and slope drains along the top edges of the embankment to intercept surface runoff.

During embankment construction, allocate adequate space in the embankment for excavated material. Begin constructing embankment by placing initial lifts in the deepest portion of the embankment. Continue placing lifts approximately parallel to the finished pavement grade line. If constructing embankments with material that is obtained from more than 1 source, do not co-mingle materials.

When constructing embankment for the specified materials, the following apply:

  1. Concrete or HMA. The Contractor may use concrete or HMA pieces to construct embankment if approved by the RE. Ensure that HMA or concrete pieces are at least 2 feet above the water table when constructing embankment.

  2. Soil Aggregate and Rock. If I-14 soil aggregate is composed of soil aggregate and rock, fill the rock voids with soil aggregate. If constructing embankments outside the ROW or easement, construct the top 30 inches with I-14 soil aggregate that contains no aggregate exceeding 2 inches in any dimension.

  3. Rock. Obtain RE approval before placing rock in embankments. Do not place rock in embankment in areas where piles or guide rail posts are to be driven, or drainage structures or utilities are to be constructed.

    Before placing rock on compacted embankment constructed of soil, grade the existing embankment surface to slope from the centerline to the sides at the rate of approximately 1 inch to the foot, and thoroughly compact the surface of the embankment.

    Place rock to form the base of embankments for the full width of the embankment. Place rock in uniform lifts to a depth that does not exceed 1-1/2 times the approximate size of the largest rock, but limited to a maximum lift depth of 3 feet. Reduce the size of rocks larger than 2 feet in any dimension. Distribute rock by blading or dozing to ensure proper placement in the embankment and to keep voids, pockets, and bridging to a minimum. Do not dump rock in final position.

    Ensure that the exterior 1-foot portion of the top and sides of rock in embankment contains no rock exceeding 8 inches in any dimension. Fill voids in the exterior 1-foot portion with granular material. Do not place rock in embankment within 2 feet of the finished subgrade elevation.

    When planting trees in the embankment, ensure that the exterior 2-foot portion of the top and sides of rock in embankment contains no rock exceeding 8 inches in any dimension. Fill voids in the exterior 2-foot portion with granular material.

    Construct the balance of the embankment with soil aggregate. Place and grade material in lifts not exceeding 8 inches, and then compact using the directed method as specified in 203.03.02.C.

When constructing embankment abutting structures before the abutments and wingwalls are completed, allow ample space for construction of the abutting structure. Construct the embankment abutting the structure at a slope of 5H:1V, or flatter. When the abutting structure is complete, finish placing the embankment to the structure. Place embankment around and adjacent to arches, rigid frame bridges, culverts, and piers simultaneously on both sides to the same elevation. Do not place embankment with pieces larger than 6 inches in any dimension within 2 feet of structures, utilities, and drainage facilities.

Place and compact material used for embankment as specified in Table 203.03.01-1:

Table 203.03.01-1 Placing and Compacting Methods

Placement Condition

Method

I-11 < 1 foot above water table or on unstable ground

End-Dumping

I-11 ≥ 1 foot above water table
I-14 – Granular material
Control Fill

I-14 – Primarily rock or non-granular material

Directed

I-9/I-10

Density Control

During embankment construction, route construction equipment, both loaded and empty, over the lifts with the travel distributed evenly over the entire width of the embankment. Before placing subsequent lifts, regrade and compact areas rutted by traffic.

The RE will check the elevation of the subgrade as specified in 202.03.03.C. The allowable tolerance from the shown elevations is ±1/2 inch.

Stabilize slopes either by temporarily seeding and mulching, or by topsoiling, permanently seeding, and mulching as specified in 806.03.01. Do not construct embankment more than 15 feet high without stabilizing the slope. Submit alternate methods for stabilizing slopes when seeding is not allowable due to seasonable constraints. Obtain RE approval of alternate methods before beginning embankment construction.

203.03.02 Placing and Compacting Methods

  1. End-Dumping Method. Do not begin end-dumping until the RE tests the bottom of the excavation to determine that the wet material has been removed down to firm bottom or the lower limit as shown on the Plans. Do not interrupt end-dumping except as necessary to allow for testing and measuring. When interrupted for more than 24 hours, do not end-dump until the RE retests the bottom of the excavated area and determines it to be in satisfactory condition.

    Sequence excavation and end-dumping to ensure that wet material does not re-enter the excavated area. End-dump the embankment material only to an elevation that allows the use of compacting equipment. Construct the remainder of the embankment using the control fill method as specified in 203.03.02.B.

    Fill and advance the embankment wedge so that the remaining wet material is forced to the sides of the excavation and is not entrapped under the embankment. Remove wet material that accumulates at the sides of the excavated area as the embankment wedge advances. Remove wet material spilled or otherwise deposited on the top or sides of the embankment during this operation.

    When widening an existing embankment, place embankment material along and outward from the existing embankment in close coordination with the excavation to prevent entrapping wet material between the existing and new sections of embankment and displacing unstable materials that may be under the existing embankment.

    Prevent settlement of or damage to existing roadways, utilities, or other facilities. Repair or replace roadways, utilities, or other facilities to the preconstruction condition.

  2. Control Fill Method.

    1. Control Strip. Construct a control strip to determine compaction requirements. Construct a new control strip for each change in the character or source of the material or for any change in the compaction equipment. Each control strip is to remain in place and become a portion of the completed embankment.

      Obtain RE approval of the subgrade or course upon which a control strip is to be constructed before constructing the control strip. Construct a 400-square yard or greater control strip consisting of 3 equally thick lifts not exceeding 12 inches each.

      >Compact each of the first 2 lifts of the control strip using the directed method as specified in 203.03.02.C.

      Compact the third lift of the control strip with a minimum of 2 passes of the compaction equipment. Continue compacting until additional passes result in no appreciable increase in density. The ME will determine density of the control strip according to AASHTO T 310 (Direct Transmission Method). Provide a final lift surface that is smooth, dense, and free from ruts and roller marks.

      After the Contractor completes compaction of the control strip, the ME will perform a minimum of 10 tests at random locations to determine the average in-place dry density of the control strip. If the average dry density of the material in the control strip is equal to or greater than 95 percent of its maximum density as determined according to AASHTO T 99, Method C, including the replacement option, then the RE will approve the compaction equipment and its method of use for compaction of embankment of the same materials and thicknesses on the Project. If the control strip fails to achieve the required density, remove and construct a new control strip. Revise compaction operations for subsequent control strips to achieve the required density.

    2. Embankment. Continue constructing the embankments in the same manner as the approved control strip. If an area is inaccessible to the compacting equipment used to construct the control strip, compact each lift to a density of at least 95 percent of the maximum density as determined according to AASHTO T 99, Method C. The ME will determine the density of such inaccessible areas from the average of 5 randomly located measurements according to AASHTO T 310 (Direct Transmission Method).

  3. Directed Method. Place embankment materials, except rock, in lifts not exceeding 8 inches thick. Place rock as specified in 203.03.01.3. Compact each lift as specified in Table 203.03.02-1.

    Table 203.03.02-1 Compaction Requirements

    Embankment Material

    Equipment

    Passes Per Lift

    Sand, Sand and Gravel Pneumatic-Tired Roller
    Dynamic Compactor
    5 minimum
    Number of passes to optimize density
    Silt, Clay Pneumatic-Tired Roller
    Padfoot Roller
    5 minimum
    8 minimum
    Rock 3-Wheel 10-Ton Roller 4 minimum
    Dynamic Compactor
    (Vibratory roller with 6-ton min. static weight at drum)
    2 to 5


    If an area is inaccessible to the compacting equipment specified in Table 203.03.02-1, compact each lift following the density control method as specified in 203.03.02.D.

  4. Density Control Method. If required, submit a dewatering plan including the method of dewatering and controlling sediment and contaminants from entering adjacent waterbodies, wetlands and environmentally sensitive areas. Dewater areas according to the dewatering plan before and during embankment construction if areas are below the water table. Construct embankment in lifts not exceeding 12 inches thick after compaction. Do not blend I-9 soil aggregate to meet gradation requirements at the placement site. Compact embankment materials to a density of at least 95 percent of maximum density. For bridge foundations without piles, determine maximum density according to AASHTO T 180, Method D, including the replacement option. For other instances, determine maximum density according to AASHTO T 99, Method C, including the replacement option. The ME will determine the compacted density of embankments by taking the average of 5 randomly located measurements for each course or at a minimum of each 3-foot increment of elevation according to AASHTO T 310 (Direct Transmission Method).

    If any individual measurement is less than 90 percent of the maximum density, or the average is less than 95 percent of the maximum density, continue compaction or take corrective action until the ME verifies that the required density is achieved.
