1 Bulk materials storage Sand, soil, woodchips and so on from bulk storage areas should be prevented from entering the stormwater system. 2 Storing and decanting chemicals Storage of dangerous goods should be licensed by the NSW WorkCover Authority, and storage of any hazardous materials should be in accordance with current legislation. 3 Bunding Effective bunding is extremely important when dealing with chemicals. Refuelling is an important depot activity but it must be well handled so that spills are avoided. 5 Mechanical workshops Regular cleaning, effective design and other measures can make workshops efficient and safe.
Nurseries can be an area of concern because of the use of fertilisers and other chemicals.
There are also a number of practices that can make nursery gardening safer and less damaging to the stormwater system. 7 Painting and signwriting It is very important to store and use paints properly. 8 Equipment storage and parking Leaks from equipment, vehicles and plant, and spills from refuelling, are significant contributors to stormwater pollution from depots. A designated area for washing vehicles should be established with hose lengths limited so that staff cannot wash vehicles outside that area. 10 Waste storage and disposal Disused car and truck batteries should be stored undercover and in a spill tray or bund.
