Re: EIS - Proposed Badgerys Creek airport.
By now your organisation would be aware of, and in possession of, the summary relating to the draft EIS into the proposed Badgerys Creek airport site. We would hope that your organisation would have had the opportunity of studying and appraising the issues raised.
Our organisation has been an opponent of an airport anywhere in the Sydney Basin for sometime. We have made numerous submissions to the Commonwealth Government, the Department of Transport, Rust PPK the consultants contracted to prepare the EIS, and SMEC the independent auditors of the EIS. Unfortunately it would appear that a number of our concerns have fallen on deaf ears, and as a result we believe that insufficient study has been applied to the EIS on a number of vital points.
We are worried with the apparent lack of concern, as expressed by the draft EIS summary, and ask that you give us your thoughts on the following matters:-
1) * "Analysis carried out for the Draft EIS does not indicate any contamination of Sydneys water supply or ecological impacts due to aerial pollutants." (Page 35)
2) * "Potential to exceed ANZECC guidelines for benzene levels in drinking water." - "Low" (for all options - pg 47). We understand that Australian water quality guidelines are set by the NHMRC, and as such wonder why ANZECC guidelines were chosen for this EIS.
a) Do you know why?
b) Are ANZECC guidelines more stringent than those set by the NHMRC?
3) * What your organisation believes would be the impact of regular long term fuel dumping/leaking into the dam itself, and the catchment area.
b) Also what your organisation considers the impact of long term routine jet exhaust would be on the dam and its catchment area could be.
4) * What the consequences would be if an aircraft were to perform a major fuel dump over the dam and its catchment, or if a fully fuel laden aircraft were to crash into the dam and/or its catchment and disgorge its entire kerosene based fuel load. (Approx 150,000 litres or more)
5) * What would be the possible consequences of an aircraft impact on the dam wall itself?
6) *What would be the impact on roof water supplies for those homes not connected to Sydney Water, due to continual routine jet exhaust, and continual fuel leaks/dumping.
7) * We have been alerted to the fact that hydro carbons become highly carcinogenic once they have come into contact with chlorine. Given that chlorine is added to the water supply at Warragamba, and at Prospect, what are contingency plans to prevent this affect?
b) Would you also please indicate what sort of repercussions might be expected in the event that the chlorine holdings at Warragamba and/or Prospect respectively, should be impacted upon by an aircraft?
We realise that the matters raised above are not an exhaustive list of possible catastrophes relating to the Sydney water supply, however we are certain that your organisation would have many further concerns with the apparent lack of concern raised by the Draft EIS. We would be interested in hearing what those concerns are.
We would also seek from you, any submission that your organisation may have made to the EIS process.
We await your reply with interest.
