3.16.1.8 Areas with natural vegetation should be preserved to the
extent possible.
3.16.2 Contaminated Site Issues
3.16.2.1 Asbestos/Lead/PCBs
3.16.2.1.1 New construction will not incorporate materials which
contain asbestos, lead or PCBs, or will only incorporate them in
environmentally acceptable forms. Designs for existing facility
alterations will normally include mitigation provisions. Mitigation
design is typically based on previously accomplished environmental
assessments, and feasibility and mitigation studies, but occasionally
may require the designer to perform environmental investigations.
3.16.2.1.2 Mitigation design will comply Federal, state and local
rules and regulations, and will normally be completed with regulatory
closure approval prior to other construction. The construction
contractor should be made liable for control and use of potentially
contaminating materials used in their operations.
3.16.2.2 Petroleum Products
3.16.2.2.1 Any environmental studies conducted prior to
development should identify whether there are on-site petroleum
contamination issues. If petroleum contamination consists of surface
spills or shallow concentrated areas, the areas are normally mitigated
by removal and disposal of the fuel and any adjacent contaminated
soil. Underground tanks should be removed and contaminated soils
disposed of, with regulatory closure prior to construction on the site.
3.16.2.2.2 Certain Government sites, usually on existing Government
installations, may be included in a larger zone of petroleum
determination that the site is developable even with the presence of
petroleum contamination. Site design should address possible vapor
emissions and accommodate any existing monitoring wells, extraction
wells or treatment facilities. Contractors will be required to have
approved health and safety operating plans in place prior to
commencing work on the site.
