will preclude dermal absorption. Whilst the public exposure during application of varnish will require the use of personal protective equipment, the dried varnish should present no possibility of exposure. 8. ENVIRONMENTAL EXPOSURE . Release There is a potential for release of the notified polymer to the environment during the manufacture, transport, secondary processing, and final use stages. At the manufacturing plant, any excess material left after filling the drums will be blended into the next batch. All filter residues are intended to be deposited in secure landfill in accordance with Local, State and Federal regulations. In the case of a spillage, it would be collected and disposed of similarly. Packaging of the aqueous dispersion of the polymer in sealed steel drums minimises the potential for release during transport. Waste from the varnish formulation process would consist of polymer residue remaining in used drums. These are consigned to landfill in accordance with Local, State and Federal regulations. Other possible release will be when painting equipment i.e. brushes, rollers etc. is cleaned and when paint cans containing excess paint are disposed of. The washings are likely to enter the drain with copious quantities of water, followed by treatment at a sewage treatment plant. Empty cans and excess paint in cans are likely to be disposed of with the normal household garbage by landfill. . Fate Most of the notified polymer will be used to coat timber and should have limited environmental exposure once cured. Waste generated during paint manufacture will be consigned to landfill, as well as any unused paint residues in cans. Most of the polymer washed down drains when brushes and rollers etc. are cleaned will be contained in the sewage sludge which will be landfilled or incinerated. The notified chemical is a polymer with low water solubility, degradation or leaching from landfill sites is not expected. Incineration of the notified substance is expected to produce water, and oxides of carbon and nitrogen. 9. EVALUATION OF TOXICOLOGICAL DATA Toxicological data are not required for polymers of NAMW > 1000 according to the Act. 10. ASSESSMENT OF ENVIRONMENTAL EFFECTS No ecotoxicological data were provided, which is acceptable for polymers of NAMW > 1000 according to the Act.
