reaction components and intermediate products may have been discharged from reaction vessels prior to production runs. Quality assurance procedures may also have included sampling points from intermediate stages in the manufacturing process which may have been allowed to drain away or be otherwise discarded on site.

    3.3.12      Product spills, losses, incidents and accidents (including fire)
These should be listed chronologically, together with an indication of the material spilled, estimates of quantity, extent of fire damage and structures affected.

    3.3.13      Discharges to land and water
The types of waste currently and historically discharged should be identified. Where practicable, the quantities should also be established.

    3.3.14      Wastes produced
This requires an understanding of the processes being performed in the industries and activities identified above. Wastes may be identified specifically (for example, waste degreasing solvents including carbon tetrachloride) or more generally (for example, acid slurry).

    3.3.15      Power generation
Many historical activities required steam as part of the process or for power generation. Before the advent of electric power, generation of steam could have progressed from solid to liquid fuels requiring fuel storage and disposal of ash. This may have resulted in contamination by fuel and combustion products, for example, polycyclic aromatic hydrocarbons (PAHs). If the power requirement was large, a sub-station with a transformer(s) may have been on site with the attendant risk of polychlorinated biphenyls (PCBs) spills. In addition, fibrous asbestos may have been used for insulation purposes.

    3.3.16      Waste disposal locations and imported fill
Locations of solid waste and liquid waste disposal areas and liquid waste lagoons, settling tanks, sumps and soak wells should be identified in the maps and figures described above. The location of any wells on site should be indicated as these may have been used historically for liquid waste disposal.

Historically, many industrial wastes and diverse contaminated fill were considered a low-cost source of material to level or elevate sites. Wastes may have originated from on-site industrial activities or have been introduced from unknown off-site sources. Residential and industrial/commercial areas around major industries (for example, coal gas works, power stations, and mineral processing plants) may have been filled with ash, coke, hydrocarbon impacted fill, metal waste and various wastes originating from the industrial activity.

Sites should be assessed for areas of fill, particularly if there are reasonable grounds to suspect the original land form has been altered such as by filling gullies and watercourses.

    3.3.17      Earthmoving activities carried out on the site
This information will assist in determining the source and location of any imported fill. Consideration should also be given to the possibility that earthmoving activity may have resulted in redistribution and burial of contamination.

    3.3.18      Interview information
Interviews with past property or business owners and
