202.03 Construction
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 mater ial in stockpiles to determine suitability for use as topsoil. Reuse or dispose of unsuitable stripped material as specified in 202.03.03.C.
202.03.02 Excavation, Test Pit
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. Ensure test pits do not exceed 3 cubic yards unless directed by the RE. 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.B.3.
202.03.03 Excavation, Unclassified
A.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, structures and existing vegetation 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 topsoil spreading, permanently seeding, and mulching as specified in 806.03.01. Submit alternate methods for stabilizing slopes when seeding is not effective 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.B.3. 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.D. Ensure that the elevation is within ±1/2 inch of the specified elevation.
1.Wet Areas. If required, submit a dewatering plan including method of dewatering and controlling sediment and contaminants from entering adjacent waterbodies, wetlands, environmentally sensitive areas and preserved trees, and other vegetation. 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 progre sses, 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.B.3. Backfill and compact the remaining excavated area using the density control method as specified in 203.03.02.B.4. 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.B.3. 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.B.3. 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. If 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 wr iting, 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.B.3.
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.B.3. 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:
a.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 t he 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.
b.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. Do not commingle different types or classifications of material. 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 dur ing 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 tech nique is arrived at that produces the desired results.
c.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.
d.Methods of Drilling and Blasting.
1.Presplitting. Perform presplitting as specified in 202.03.04.
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.
B.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. Do not commingle different types or classifications of material. 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.
C.Reuse or Disposal of Excess Material
1.Reuse. Before using other excess materials, reuse regulated material and APS 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 wat er table or within 2 feet of any underground utility. Compact material using the directed method as specified in 203.03.02.B.3. Dispose of excavated material that will not be reused as specified in 202.03.03.C.2.
2.Disposal. Dispose of excess regulated material as specified in 202.03.09. 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.
a.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.
b.Obtain the potential owner's notarized authorization of the acceptance of the excess mate rial. 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. When sampling results indicate that the material is regulated, and with RE approval, dispose of the material as specified in 202.03.09.
c.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 201.03.01.H.
D.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 chan ges in grade so that intermediate longitudinal checks can be made.
202.03.04 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 hole s 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 e quipment 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 t he 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 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.
202.03.05 Excavation, Regulated Material
The Department, as the generator, is solely responsible for the designation of excavated material. Regulated material excavation consist s 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 E-1-8. Areas of known regulated material are identified on the Plans. Handle regulated material according to applicable Federal, State, and local laws, rules, and regulations; NJDEP Technical Guidance Documents and as specified herein. Dispose of regulated material as specified in 202.03.09.
1.Pre-Excavation Plans. Submit 4 copies of the following plans to the RE 30 days before beginning construction operations. Update an d resubmit plans to identify changes in the condition or operation of the W ork. If the Contractor fails to follow the pre-excavation plans, the RE will suspend the Work.
a.Site-Specific Health and Safety Program (HASP). Perform a hazard assessment of each proposed work task, and make independent evaluations regarding the appropriate level of health and safety requirements. Employ a Certified Industrial Hygienist (CIH) or Certified Safety Professional (CSP) to develop and oversee the Site -Specific HASP. Ensure the CIH/CSP prepare s the Site-Specific HASP to protect the Contractor’s employees, the subcontractor’s employees, the Department’s employees and consultants, and the public from contamination present in the areas requiring excavation as shown on the Plans. Ensure that the Site-Specific HASP complies with Federal, State, and local laws, rules, and regulations, including the health and safety requirements of OSHA 29 CFR 1910 and 29 CFR 1926. Implement the Site-Specific HASP, as approved by the RE, at the beginning of construction operations. Ensure that the CIH/CSP reviews site -specific data and addresses the proposed ac tivities to the level of detail needed to ensure that site -specific data, appropriate regulations, and a description of the site conditions are incorporated into the Site-Specific HASP. Describe workplace and emergency procedures so that the Project is con structed in a safe manner. The Site-Specific HASP governs all facets of the Project and encompass the activities of all persons who enter or work on the Project. Incorporate procedures that conform to Federal, State, and local laws, rules, and regulations pertaining to employee working conditions where appropriate, National Institute for Occupational Safety and Health, OSHA, USCG, EPA, and NJDEP. Include requirements for a health and safety coordinator to monitor the working conditions during excavation p rocedures and during the handling of regulated material to ensure conformance with the approved Site -Specific HASP. Ensure t he CIH/CSP evaluate s the need for air monitoring during excavation and loading operations of regulated material. If deemed necessary, ensure the CIH/CSP or an assigned coordinator, suitably trained and approved by the CIH/CSP for the work required, implements the air monitoring program. Ensure the CIH/CSP includes in the Site-Specific HASP applicable training and qualifications documentation for each health and safety coordinator. If deemed necessary by the CIH/CSP, provide initial and annual training and medical monitoring for Contractor employees scheduled to work in or with regulated material and, per the RE’s request, up to 10 Department employees or their authorized representatives as specified in OSHA 29 CFR 1910. Provide the initial training for State employees or their authorized representatives 30 days before excavating
b.Materials Handling Plan. Develop a Materials Handling Plan (MHP) for regulated material encountered, moved, and disposed of or recycled during construction. Ensure the MHP includes the following:
1.Techniques to be used in managing regulated material to protect adjoining properties and workers and visitors to the Project Limits against exposure to regulated material and to prevent release of regulated material to the environment.
2.Standard operating procedures for excavation, stockpiling, transporting, measurement, and disposal of regulated material.

8.Requirements of the receiving facility to accept the regulated material. Implement the MHP, as approved by the RE, at the beginning of excavation. Perform planning, administrative, and control functions required to implement the MHP.
c.Pollution Prevention and Control Plan. Develop a Pollution Prevention and Control (PPC) Plan describing the methods of preventi ng discharge of regulated storm water, ground water, sediments, and free product during stormwater control, excavation, and dewatering operations. Prepare the PPC Plan according to Federal, State, and local laws, rules, and regulations relative to regulated discharges. Implement the RE approved PPC Plan before beginning excavation. Detail methods, personnel, equipment, and reporting requirements on how to discharge regulated stormwater, groundwater, sediments, and free product during stormwater control, excavation, and dewatering operations into a dewatering basin, storm/sewer system, or other approved system. Specify methods and equipment for collecting, pumping, treating, monitoring, and disposing of liquids generated by stormwater control. Specify measures to prevent stormwater run -on and runoff and measures for dewatering of excavations, dewatering of sediments, decontaminating personnel and equipment, and storing fuels and chemicals. Include detailed water collection, treatment, monitoring, discharge activities, and reporting requ irements. Provide daily construction reports to the RE to identify water collection, treatment, monitoring, and discharge activities; personnel and equipment; and relevant quantities. When dewatering in areas of petroleum contamination, provide an oil-water separator with the dewatering basin or sediment control tank as specified in 158.03.02.
2.Excavating. Excavate regulated material as specified in 202.03.03 and as shown on the Plans.
3.Temporarily Storing. Temporarily store regulated or hazardous material in stockpiles in well-drained areas no closer than 50 feet from streams, wetlands, floodplains, or other waterbodies within the Project Limits and as shown on the Plans . Construct stockpiles on polyethylene sheeting. Do not commingle different types or classifications of material. Contain stockpiles with haybales or silt fence placed continuously at the perimeter of the stockpiles. For hazardous material, if a stockpile area is not available within the Project Limits, sample and analyze materials in -situ for disposal. Excavate and place the hazardous reg ulated material directly into trucks, and haul it directly to the approved disposal facility. Cover stockpiles with polyethylene sheeting. Secure the cover in place at all times. Overlap joints in the polyethylene sheeting a minimum of 12 inches, and pla ce securing materials along the joints. Maintain the cover, and replace damaged polyethylene sheeting as needed. Clean equipment used for the movement of excavated material at the end of each working day or before removing it from the Project Limits. Ins tall non-vegetative erosion control features to limit the movement of the excavated material from equipment cleaning areas. Temporarily store the excavated material from equipment cleaning in stockpiles. If regulated material is not designated for reuse on-site, dispose of regulated material within 180 days of being stockpiled as specified in 202.03.09. Do not reuse hazardous regulated material. Dispose of hazardous regulated material as specified in 202.03.10 within 90 days of being stored in stockpiles.
4.Document Control. Provide the following items:
a.Soil/Sediment Usage Tracking Log. Complete a tracking log for each working day involving excavation, stockpile, transport, and disposal of regulated material. Monitor and record the following information on the tracking log:

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.
202.03.06 Excavation, Acid Producing Soil
The Department, as the generator, is solely responsible for the designat ion 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.
1.Pre-Excavation Plans. Submit a Materials Handling Plan as specified in 202.03.05.1.
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. Do not commingle different types or classifications of material. Place stockpiles in well-drained areas no closer than 50 feet from streams, wetlands, floodplains, or other waterbodies, and as shown on the Plans. 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 mater ials 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 48 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.Document Control. Perform document control as specified in 202.03.05.4, except that PPC logs are not required.
202.03.07 Acid Producing Soil Remediation
Remediate the soil by covering the APS with a layer of pulverized limestone applied at a rate of 6 tons per acre (275 pounds per 1,000 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 surfac e (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 , except pavement for permanent erosion control.
202.03.08 Removal of 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 with in 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 202.03.03.C. Do not commingle removed pavement with any other material if stockpiled.
202.03.09 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 202.03.03.C.2. Pay fees associated with removal and disposal of regulated materials. Perform soil sampling and analyses according to disposal facility requirements and the Site-Specific HASP. Provide a copy of sampling log, chain of custody form, and analytical report to the RE. Procedures for sampling should be in accordance with the NJDEP Field Sampling Procedures Manual, NJDEP Technical Requirements for Site Remediation, NJDEP Management of Excavated Soils Guidelines, Appendix 1 of the NJDEP Waste Classification Form, and EPA requirements. Submit the 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. Ensure the licensed hauler transports the regulated material to the disposal/recycling facility with no unauthorized stops in between, except as required by regulatory authority. Ensure the hauler uses 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.
202.03.10 Disposal of Regulated Material, Hazardous
Load, transport, and dispose of hazardous regulated material for the Project according to Federal, State, and local laws, rules, and regulations and as specified in 202.03.03.C.2.

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 fo rm 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 regulati ons 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 man ifest discrepancy letters to the Bureau of Environmental Program Resources. Ensure t he licensed hauler transport s the hazardous regulated material to the disposal/recycling facility with no unauthorized stops in between, except as required by regulatory authority.
