Use scenarios for the phosphate additive Alkyl phosphate additive products currently sold in Australia include Valvemaster Concentrate and Valvemaster VM11. The chemical composition and addition rates for LRP of these products is described in Section 4 and and Section 7.2, respectively. The two LRP use scenarios (‘present’ and ‘2004’) developed in Table 2 have been used to estimate the tonnage of Valvemaster Concentrate likely to be used in Australia in these time periods (Table 3). Due to the commercial-in-confidence nature of the information provided by the Applicants, the calculated tonnage of the alkyl phosphate additive is not disclosed. The estimated tonnage of phosphorus per annum for the two use scenarios is based on 5.1% wt phosphorus in Valvemaster Concentrate.
