1.5.3 Any hazardous or special waste generated shall be handled in accordance with all local, state, and federal laws and regulations, including Resource Conservation and Recovery Act (RCRA) requirements for waste management and Department of Transportation (DOT) requirements for waste transport. The Contractor shall be responsible for obtaining all necessary permits, licenses, and approvals unless otherwise specified in writing by the CO.

01620- 4

1.6 HAZARDOUS WASTE GENERATION/DISPOSAL

1.6.1 The Contractor shall maintain records of all waste determinations, including appropriate results of analysis performed, substances and sample locations, date and time of collection, and other pertinent data as required by 40 CFR 262 Subpart D, 40 CFR 279.11 and 40 CFR 280.74.

1.6.2 The Contractor shall provide a copy of all hazardous waste manifests to the CO by close-of- business on the same day waste is transported off base. The Contractor shall provide a closed copy of the hazardous waste manifests not later than 30 days after the waste is transported off base or before final payment, whichever occurs first. Since CAFB’s EPA identification number will be used on all hazardous waste manifests, 14 CES/CEIE shall sign the manifest. The Contractor still retains all liabilities associated with containerizing, loading, shipping, and disposing of the hazardous waste.

1.7 DISPOSAL & RECYCLING

1.7.1 The Government, at Government expense, will support recycling and diversion within limits as follows.

It is in the Government’s best interest to provide appropriate size containers for the collection of materials, the Contractor shall transport them to the recycle facility and process the materials. Contractors are responsible for the cost of the disposal of all solid waste and hazardous waste not surrendered for recycling on CAFB.

1.7.2 Further diversion of construction debris (C&D) is encouraged. The tonnage of reused asphalt, concrete, wood, and other materials is reportable to the CO for the duration of the project.

1.7.3 Contractors may elect (via the task order) to manage their own recycling of materials. In such cases, tonnage (weight slips) of material disposed of and reused or recycled (including reports of “no activity” in a given month) shall be reported to the CO no later than the fifth (5th) of each month until the contract is completed.

1.7.4 The Contractor shall notify the CO a minimum of three (3) calendar days prior to the need for recycle materials containers or changes in container size or delivery schedule so the appropriate containers and delivery schedule can be established. The Contractor may elect to transport materials directly to the CAFB recycling facility during hours of operation, but this is not a reimbursable action.

1.7.5 The Contractor is encouraged to contact Environmental, CEIEC or the CAFB Recycling Center for on-base recycling.

1.7.6 The following materials are acceptable for inclusion in the container provided for recycling:

• Copper: sheeting, wire, devices with an extension cord, electronics, motors.

• Steel: iron, sheet, structural beams, components

• Aluminum: sheet, structural components, cast material and containers.

• Lead: batteries, sheeting, pipe

• Paper: cardboard, office paper, mixed paper

01620- 5

1.7.7 The following items may be included in the provided containers with exceptions as noted. Again, the saving to the contractor is the avoided disposal fees.

• Oversized materials (limbs/steel/aluminum) may not need reducing by the Contractor.

Contact the recycling center directly to have exceptions inspected for handling at Government expense.

• Glass: bottles only, not mixed with construction debris collection. Office material recycling allows for the mixing of paper/glass/cans/plastic to be dropped off at the recycling center during business hours.

• Wood/scrap lumber/limbs: under 8” diameter, nail/screw/mixed material free. Wood not meeting the criteria are construction debris.

• Only plastics labeled as PETE (#1) or HDPE (#2), empty of any liquid or dry material.

Rinsing is not required.

• Other materials shall be cleared with the recycling staff.

• C&D diversion on or off base is reportable in tons to the CO. Items and exceptions are:

o Wood: limbs, pallets, clean straight lumber scrap may be collected for wood mulch BUT no screws, hardware, metal straps, bolts, plastic, Formica or treated products are wanted. The dumping of unwanted materials is a contract violation, and the Contractor will be directed to dispose of the material properly at their expense.

o Concrete: as fill, riprap, cut and reused, or crushed.

o Asphalt: millings used for new construction.

o Gravel: used decorative gravel may be counted as a diverted material if it is suitable for another purpose. Plastic and other materials are to be removed prior to reusing as ground cover.

1.7.8 Materials NOT meeting any of the above criteria will be considered “construction debris” and shall be disposed of at the Contractor’s expense. The following are examples of construction debris:

• Foam, Styrofoam, sheet plastic contaminated with dirt, furniture, chairs, office dividers, plate glass, glass objects, table-tops, Pyrex, Wood with nails or paint, brick, masonry, sheetrock.

1.7.9 Liquids are generally not acceptable. Oil may be recycled but not in the provided mixed material container.

1.7.10 Mixed material items are generally not acceptable. The Contractor shall NOT recycle pressurized containers, containers with free liquid, free solids, or other material. Any container puncturing, emptying, 01620- 6 crushing, or cutting SHALL be in accordance with MDEQ and installation air, water, and disposal regulations and permit conditions.

1.8 PROHIBITED MATERIAL/ACTIONS

1.8.1 If materials not indicated in the current contract requirements are encountered that may be dangerous to human health upon disturbance at any time, such as polychlorinated biphenyl's (PCBs), lead-based paint, and friable and non-friable asbestos, the Contractor shall take no action that would disturb or further disturb the material encountered and shall notify the CO, and assigned Quality Assurance Evaluator (QAE) or Construction Inspector (CI) immediately. Failure to make such notification relieves the Government from all liability for cost and/or performance time impacts until such time proper notifications are received by the CO.

Verbal notification shall be followed up with written notification within three (3) workdays.

1.8.2 Class I Ozone Depleting Substances (ODS) as defined in Section 602(a) of the Clean Air Act shall not be used in the performance of this contract. Radioactive materials or instruments capable of producing ionizing radiation—as well as materials that contain asbestos, mercury or PCBs—are also prohibited, as are materials that contain potentially hazardous concentrations of lead. The Consumer Product Safety Commission states that potentially hazardous concentrations of lead are greater than 90 parts per million or 0.009%. Exceptions to the use of the above excluded materials may be considered by the CO, upon written request by the contractor; however, their use is a violation of federal law, Air Force Instruction (AFI), executive orders, or policy.

1.9 SPILLS AND CLEANUP

1.9.1 If there is a spill—of any amount or type—of hazardous materials or waste to include all petroleum products, the Contractor shall immediately call 911 to call the installation fire dispatch providing description of material spilled (including SDS), time and location of spill, estimate of amount spilled, spill surface, and path of spill (i.e., Did the material enter or will it soon enter a drain inlet, waterway, soil, etc.). Note that spills used here include releases of materials from ruptured or leaking storage receptacles (such as tanks), from transmission lines and valves, either as a part of contract work or as a result of contract work on nearby storage or transmission lines, or the leak of hazardous gases such as chlorine into the air. A follow-up written report to the CO shall be required within three (3) calendar days.

1.9.2 The Contractor shall take immediate action to contain and clean up spills. If the Contractor is unable to begin cleanup action within 15 minutes of the spill, the Government reserves the right to begin cleanup, continue cleanup efforts/actions until the Contractor can properly take over, or enlist the services of another Contractor to begin and continue cleanup as determined by the CO.

1.9.3 All costs incurred by the Government until Contractor are capable of taking control, as determined by the on-scene commander, will be the sole responsibility of the Contractor. The Contractor shall ensure equipment, material, and trained personnel are available to meet response times and cleanup requirements.

01620- 7

1.9.4 Spill cleanup personnel shall be trained and certified to perform spill cleanup. The Contractor shall assume responsibility for the proper characterization and disposal of any waste and cleanup materials generated. All waste and associated cleanup material shall be removed from the base and transported/stored in compliance with applicable regulations until final disposal.

1.9.5 The Government may control spill cleanup activities. The on-scene commander will determine best practices for spill cleanup. The CO remains as the only Air Force representative who may amend contract requirements.

1.9.6 The Contractor is responsible for restoring a spill site to the condition of the site prior to the spill or to an improved condition.

1.10 AIR CONSIDERATIONS

CAFB is in an air attainment zone. The base operates under a true minor permit that requires extensive data gathering to verify no violations of the permit. Fueling operations, painting other than buildings, media blasting, and dust generation require reporting to the CO. The requirements for monthly reporting, if needed, shall be coordinated with the CO.

1.11 AFFIRMATIVE/GREEN PROCUREMENT/BIO-BASED/ENERGY

Pursuant to Executive Order 13834, energy and materials used on government installations should be procured in a manner that increases efficiency, optimizes performance, eliminates unnecessary use of resources, and protects the environment. For example, whenever possible—and assuming comparable quality, availability, and price—supplies are to be of the appropriate minimum energy efficiency or better;

made from re-covered, recycled, or renewable materials. Certified materials with appropriate labeling are a good guide. The CO has fiduciary obligation to follow executive orders and enforce them on the Contractor.

1.12 ASBESTOS/LEAD BASED PAINT

1.12.1 After coordination with the CO, all asbestos manifests shall be signed by 14 CES/CEIE Hazardous Waste manager before leaving the installation. Deliver a copy of certifications to the CO three (3) calendar days before start of work.

1.12.2 No lead-based paint will be utilized by any Contractor on any base facility or equipment. Removal of paint or disturbing of surfaces may result in being exposed to lead-based paint. All such loose material, chips, and debris shall be removed and not allowed to contaminate the ground or other areas as part of the contract work. All lead-based paint and contaminated dust/chips shall be surrendered to the Government following coordination with the CO and CE Construction Management. Government will dispose of such dust/chips at Government cost.

01620- 8

1.13 DRINKING WATER

1.13.1 Report water main breaks immediately. The base 911 system will take emergency reports and after-hours calls. The Contracting Office may become involved with liability or repair issues. Note: cell phone users will be transferred to CAFB dispatch when they identify their location.

1.13.2 Back Flow Prevention is MANDATORY on all connections to the drinking water system. The Contractor shall not take water directly from hydrants for Contractor use without using a back flow preventer.

Drinking water utility use may be metered; estimated use shall be agreed to in advance.

1.14 ENVIRONMENTAL MANAGEMENT SYSTEMS (EMS)

1.14.1 Upon reading and signing the contract all Contractors are considered to have met the EMS General Awareness training requirements. It is the expressed responsibility of the Contractor to ensure all employees and sub-contractors are aware of all environmental requirements stated herein. Where workers are transitory (less than 160 hrs. annually), the requirement may be waived as long as a supervisor or foreman is trained.

The USAF does NOT automatically recognize ISO 7000 or 14001 training or certification as equivalent.

1.14.2 All Contractors are required to be aware of the CAFB Environmental Policy Statement which is:

CAFB is committed to conducting the mission in a manner that will adhere to federal, state and Air Force standards and protect human and environmental health. In support of our goal, we shall:

• Maintain a culture of continuous improvement to daily activities which impact environmental and occupational health.

• Identify and act to reduce waste and prevent pollution of all kinds.

• Promote conservation and sustainable use of natural resources.

• Develop economically feasible and environmentally sound objectives and targets to address significant aspects.

1.14.3 The framework for setting and reviewing environmental objectives and targets is a cooperative effort between all base personnel, Cross Functional Team (CFT) and Environmental, Safety and Occupational Health (ESOH) Council.

1.14.4 All contractors must understand that all on-base activities are scored and those scored highest are critical and are identified as “significant aspects.” The most significant aspect at CAFB is storm water quality. The Contractor shall take particular care with activities that could affect this area; to include, but not limited to, activities causing erosion/sediment runoff.

1.15 HISTORICAL AND CULTURAL ARTIFACTS

Upon discovery of human remains, pottery, or other artifacts that may or may not be of Native American origin, the work site SHALL BE secured, work in the area of discovery SHALL be halted, and the contracting

01620- 9 officer SHALL immediately be notified. Contractor shall also immediately notify the CO about any damage to such artifacts. The worksite shall be released to the CO (or all practical portions) by 14CES/CEIE archaeological representative. Although CAFB has no registered historic buildings or sites, there are culturally significant attributes of the chapel, there is a known cemetery on site, and WWII debris could be discovered.

1.16 NATURAL RESOURCES

1.16.1 The Contractor shall preserve natural resources within project boundaries and outside limits of permanent work and shall not cut, deface, or remove trees or shrubs without CO permission unless allowed under the contract. The Contractor shall protect existing trees that may be damaged by contractor activities.

Do not fasten ropes, cables, or guying to trees without CO approval.

1.16.2 The Contractor shall not disturb fish and wildlife nor alter water flows or significantly disturb native habitat adjacent to the project site.

1.17 NOISE

Noise in excess of 85dB within 50 feet of occupied space shall be avoided, muffled, baffled, or of short duration. Occupants are to be notified in advance should long-term (6hrs or more) noise be anticipated due to contractor work.

1.18 PESTICIDES/FERTILIZERS

1.18.1 Contractors shall be licensed to apply any pesticide and shall coordinate and report all pesticide and fertilizer application with the CO. All quantities used/applied shall be reported by the 5th of the month.

1.18.2 If pest control, termite treatment for new slabs, or any type of similar actions are required by the Contract, see individual task order for additional requirements.

1.19 STORM WATER PROTECTION

1.19.1 CAFB has a Mississippi Baseline Storm Water General NPDES Permit. All discharges to storm drains, surface water, or indirectly to the ground are regulated and reportable. Even “clean” water is subject to the permit. The washing of vehicles will be in designated areas only. The use of soap is strictly prohibited. Wash water will not be dumped on the ground, parking lots, or in storm drains. Paint and paint brushes shall NOT be rinsed outside. Such actions shall be done in a sink that has a septic hookup. Options may include capture of all fluids and transfer to an agreed upon sanitary sewer dump point. Situations and specifics are open to discussion; however, fluids shall not be disposed of on the ground without MDEQ approved Industrial Storm Water Permit modification.

1.19.2 Work sites are to be inspected at least weekly, and records of these inspections are to be maintained onsite and available upon request.

01620- 10

1.19.3 If any project involves soil disturbance (including open excavations and staging areas), surface water diversion methods shall be taken in order to minimize entrance of runoff into the excavations. If site characteristics present a potential for sediment removal due to storm water, drains in the area shall be protected using wattles, silt screens, drain seals, or other approved equivalent sediment control methods.

1.20 REQUEST FOR CE SERVICE/ACTION/CLEARANCE; AF FORMS 332/813

1.20.1 AF Forms 332/813 are the specific forms for getting Government furnished space repaired, clearing trenching operations outside of the originally identified work area, or bringing in/ending an operation. The CO shall help to coordinate these documents, if and when needed.

1.20.2 The Contractor shall use Mississippi One Call 811 before the start of any dirt work.

1.21 TANKS

1.21.1 The Contractor shall prevent oily or other hazardous substances from entering the ground, drainage areas, or local bodies of water. Secondary containment is required around temporary fuel oil or petroleum storage tanks of any size, if any leakage could enter a storm drain, ditch or other waterway. Notify the CO prior to bringing any tanks onsite. Any container 55 gallons or greater is regulated as requiring secondary containment in the state of Mississippi.

1.21.2 Contractor tanks shall meet all tank, air, and storm water requirements, be in good repair, not rusted, labeled, sheltered, and be removed when no longer needed.

1.22 LIMITS AND EXCEPTIONS

1.22.1 General: These guidelines apply to all Contractors working on CAFB, except those with tasks transient in the nature (such as delivery operations that have no other presence on base).

1.22.2 EMS Training: Services of a transitory nature may be exempt from EMS training. Qualifying transitory contracts have very limited presence on the installation, making EMS training impractical. The CO is to include all Contractors unless there is a compelling reason not to.

Example: A carpet cleaning service working completely out of a service truck, preforming a single short-term task, having no on-site presence would qualify as exempt. A lawn service storing fuel overnight would not. Non-resident delivery and freight services are exempt (such as FedEx).

1.23 BARRICADES

1.23.1 Adequate barricades and warning signs shall be furnished, installed, and maintained by the Contractor.

PART 3 EXECUTION

3.1 EXCAVATION

Excavation will be performed to the lines and grades indicated. Earth excavation will include removal and disposal of material not classified as satisfactory for backfilling. During excavation, material satisfactory for backfilling will be stockpiled in an orderly manner. Excavated material not required or not satisfactory for backfill will be removed from the site and will be disposed of off Government property. Grading will be done as may be necessary to prevent surface water from flowing into the excavation, and any water accumulating therein will be removed to maintain the stability of the bottom and sides of the excavation.

Unauthorized over-excavation will be backfilled in accordance with paragraph “BACKFILLING AND COMPACTION” at no additional cost to the Government.

3.1.1 Trench Excavation

The trench will be excavated as recommended by the manufacturer of the pipe to be installed. Trench walls below the top of the pipe will be sloped, or made vertical, and of such width as recommended in the manufacturer's installation manual. Where no manufacturer's installation manual is available, trench walls will be made vertical. Trench walls will be shored, cut back to a stable slope, or provided with equivalent means of protection for employees who may be exposed to moving ground or cave in as required by Occupational Safety and Health Administration. Special attention will be given to slopes which may be adversely affected by weather or moisture content. The trench width below the top of pipe will not exceed 24 inches plus pipe outside diameter (O.D.) for pipes of less than 24 inches inside diameter and will not exceed 36 inches plus pipe outside diameter for sizes larger than 24 inches inside diameter. Where recommended trench widths are exceeded, redesign, stronger pipe, or special installation procedures will be utilized by the Contractor. The cost of redesign, stronger pipe, or special installation procedures will be borne by the Contractor without any additional cost to the Government.

3.1.1.1 Bottom Preparation

The bottoms of trenches will be accurately graded to provide uniform bearing and support for the bottom quadrant of each section of the pipe. Bell holes will be excavated to the necessary size at each joint or coupling to eliminate point bearing. Stones of two (2) inches or greater in any dimension, or as recommended by the pipe manufacturer, whichever is smaller, will be removed to avoid point bearing.

3.1.1.2 Removal of Unyielding Material

Where over depth is not indicated and unyielding material is encountered in the bottom of the trench, such material will be removed four (4) inches below the required grade and replaced with suitable materials as provided in paragraph “BACKFILLING AND COMPACTION”.

3.1.1.3 Removal of Unstable Material

Where unstable material is encountered in the bottom of the trench, such material will be removed to the depth directed and replaced to the proper grade with select granular material as provided in paragraph

02222- 5

“BACKFILLING AND COMPACTION”. When removal of unstable material is required due to the fault or neglect of the Contractor in his performance of the work, the resulting material will be excavated and replaced by the Contractor without additional cost to the Government.

3.1.1.4 Excavation for Appurtenances

Excavation for manholes, catch-basins, inlets, or similar structures will be of sufficient size to permit the placement and removal of forms for the full length and width of structure footings and foundations as shown. Removal of unstable material will be as specified above. When concrete or masonry is to be placed in an excavated area, special care will be taken not to disturb the bottom of the excavation. Excavation to the final grade level will not be made until just before the concrete or masonry is to be placed.

3.1.1.5 Jacking, Boring, and Tunneling

Unless otherwise indicated, excavation will be by open cut except that sections of a trench may be jacked, bored, or tunneled if, in the opinion of the Government Representative, the pipe, cable, or duct can be safely and properly installed and backfill can be properly compacted in such sections.

3.1.1.6 Stockpiles

Stockpiles of satisfactory and unsatisfactory and wasted materials will be placed and graded as specified.

Stockpiles will be kept in a neat and well drained condition, giving due consideration to drainage at all times. The ground surface at stockpile locations will be cleared, grubbed, and sealed by rubber-tired equipment, excavated satisfactory and unsatisfactory materials will be separately stockpiled. Stockpiles of satisfactory materials will be protected from contamination which may destroy the quality and fitness of the stockpiled material.
