3.0 Environmental:

3.1 Sediment and Erosion control plan

3.1.1 The project design will include a sediment and erosion control plan IAW State of Delaware Department of Natural Resources and Environmental Control (DNREC) standards. The plan will be titled “Recommended Erosion and Sediment Control Plan” and will include a standard list of Dover Air Force Base specific erosion and sediment control notes. The Contractor will prepare and submit an erosion and sediment control plan prior to initiating any ground disturbing activity. The plan may consist of the already reviewed “Recommended Erosion and Sediment Control Plan” as indicated on the contract drawings, a modified version of the plan indicated on the contract drawings, or another plan prepared by the Contractor. Whichever alternative is selected, the Contractor shall submit the plan to the Dover AFB Environmental and Engineering Flights for review and coordination to ensure compliance with applicable federal and state regulations.

3.1.2 Dover AFB will review the submitted plan for compliance. Dover AFB shall provide comments be implemented or provide a "Review Complete" status for the plans.

The plans submitted with the contract drawings already have a "Review Complete" status but still shall be submitted to Dover AFB. If the Contractor chooses to revise the "Review Complete" Sediment and Erosion Control Plan provided in the contract drawings, any delays or increase in costs resulting from the revised Plan shall be the sole responsibility of the Contractor. Upon receiving a "Review Complete" status, the Contractor must file the Notice of Intent with the EPA for this project. The Contractor is the holder of the sediment and erosion control permit, not Dover AFB. A copy of the filed Notice of Intent shall be provided to Dover AFB. (Note: The EPA does not review drawings, but if they perform an inspection, the drawings shall be made available to them.)

3.1.3 Pre-construction conference - Before initiating construction, the Contractor shall schedule and coordinate a meeting to include the Contractor, the associated certified

Appendix Q Page 9 construction reviewer (CCR) (see paragraph entitled "Compliance during Construction" below) and Dover AFB representatives. No construction shall begin until the plans have been reviewed, the Notice of Intent filed and the pre-construction meeting has occurred.

3.1.4 Compliance during Construction

The Contractor shall ensure permit compliance during the term of the permit. To ensure continued compliance, the Contractor shall have a licensed certified construction reviewer (CCR), as defined by the DNREC Sediment and Storm Water Regulations, Section 12.0, to perform weekly inspections as required by those same regulations.

3.1.5 CCR reports

3.1.5.1A copy of the completed CCR reports shall be provided to Dover AFB at the end of each month. Dover AFB, however, reserves the right to request these reports more frequently if problems persist or an issue of non-compliance SECTION 01 57 13 Page 1 Invitation for Bids, W912BU-08-B-0002, is observed.

3.1.5.2 Dover AFB CCR inspections - Dover AFB CCRs will perform an independent inspection at their discretion to ensure continued compliance with the submitted plan and contract requirements. A copy of the Dover AFB CCR reports can be obtained by the Contractor upon written request.

3.1.6 Changes

In-field Changes shall be submitted prior to implementation and shall be reviewed by all applicable entities in the Civil Engineer Squadron. Particularly, environmental compliance changes, i.e. changes to sediment and erosion control practices, will be reviewed by the environmental flight. These requested changes shall still comply with all applicable federal and state environmental regulations.

3.1.7 Non-compliance issues

3.1.7.1 Dover AFB Non-Compliance Issues

After non-compliance issues are identified on either the Contractor's internal CCR reports or a Dover AFB CCR report, the Contractor shall address the situation within the workweek (5 workdays). If long-term repairs are necessary, a continuance of 5 days may be granted. Repeated non-compliance or ignoring non-compliance issues will result in a deficiency notice issued through the Contracting Officer. Deficiency notices shall constitute a violation of environmental requirements and will result in less favorable reviews pertaining to environmental compliance on subsequent projects at Dover AFB.

Continued deficiency notices will result in work stoppage by the Contracting Officer to correct sediment and erosion control issues. This type of work stoppage will not add additional days to the end of the contract for completion.

3.1.7.2 Regulatory Non-Compliance Issues

Continued non-compliance issues identified on Contractor's CCR and/or Dover AFB CCR reports may be forwarded to the EPA enforcement division for their action.

EPA enforcement issues resulting from forwarding of CCR reports or from an unannounced EPA inspection, will be resolved between the permit holder (the Contractor) and the EPA.�

Appendix Q Page 10

3.2 Energy Policy

3.2.1 All construction shall comply with energy conservation standards set by latest version of UFC 3-400-01.

3.3 Termite Treatment: All new below grade and at-grade construction shall utilize materials which are not susceptible to insect infestation. Termite treatment is therefore not required and shall not be incorporated in project requirements.

3.4 Underground oil storage tank removal: oil shall be pumped out and placed where government indicates. Dispose of all residual waste (sludge), cleaning water (triple rinse) and clean tank (tank shall be rendered useless by punching holes in it or cutting into pieces).

3.5 Asbestos abatement: Survey all possible materials (do not forget floor tiles under carpet and determine number of layers of floor tile). Remove all asbestos materials unless approved otherwise.

3.6 Lead-based paint removal: It is usually more cost effective to demolish and dispose of lead-painted items than to remove paint from them. Survey all painted surfaces that will be affected by construction.

3.7 Soil Disposal Procedures

3.7.1 The BCE will upon request, identify potentially contaminated soil and groundwater in the vicinity of any proposed demolition of facilities and subsequent construction of new facilities. Groundwater and soil may potentially be contaminated and if encountered needs to be addressed appropriately during design.

3.7.2 No known soil contamination may be present; however, the industrial activities associated with some facilities may lead to the potential for the identification of contaminated soil during construction. Therefore, any soil deemed for removal off-site must be analyzed to determine proper disposal avenues. Project designs should include unit price items for disposal of contaminated soils.

3.7.3 Each stockpile of soil needs to be analyzed for the following items:

a) Full toxicity characteristic leach ate procedure (TCLP) to include ignitability, reactivity, corrosiveness, metals, organics, pesticides, and herbicides.

b) Total petroleum Hydrocarbons (TPH)

c) Polychlorinated Biphenyls (PCBs)

d) Benzene, Toluene, Xylene, and Ethyl Benzene (BTEX)

e) Percent Solids

3.7.4 The sample results shall be submitted to CES/CEA for interpretation. CEA will be utilizing the hazardous waste limitations when evaluating the TCLP results to determine if the soil shall be disposed of as hazardous waste. The other remaining parameters are required for disposal at a Delaware Solid Waste Authority facility and have associated

Appendix Q Page 11

DSWA limitations. Those limitations will be compared to the results to determine if the soil can be disposed of accordingly at the disposal facility permitted to accept hazardous waste. If the soil in non-hazardous waste but does not meet the limitations of the DSWA, the soil shall be disposed of at a disposal facility permitted to accept such waste.

3.8 Recycled Construction Material: Contractors are required to submit their recycled construction material on the DAFB Construction & Demolition Debris Worksheet on a quarterly basis. Contact BCE for specific recycling requirements and latest worksheet.
