Dear Mr White,
Comparison of Badgerys Creek
Potential Sites for Sydneys Second Airport
Sydney Airport Community Forum Inc (SACF Inc) represents around thirty airport community groups from Randwick to the Blue Mountains, and from Hornsby to Sydneys South-West extremities. It was established as an alternative to the government-appointed committee of a similar name which is not representative of the communities affected. SACF Inc is the peak community body in respect of airport matters, with other groups of groups, such as the Coalition of Airport Action Groups and the Eastern Coalition of Airport Groups, recognising SACF Inc as the communitys true peak representative body.
Last month, in response to the Minister for Transports public statements that he was aware of the results of your yet-to-be-completed EIS supplement, we put out a media release addressing some of our concerns with the corruption of process involved with the Badgerys Creek EIS. That document is attached.
Our member organisations do not believe PPK is capable of conducting an independent EIS as required by the Environment Protection (Impact of Proposals) Act 1974 (Cth) and its Administrative Procedures by virtue of the fact that your parent organisation is one of the largest private landholders in the environs of the proposed airport site, and hence your group of companies has a direct multi-million dollar interest in the outcome of the decision. Hence we believe that you are not independent. Furthermore, the fact that a number of key public sector positions regarding environmental management/control of the aviation industry within Sydney are filled with staff seconded from your organisation (rather than the technically independent public sector) further compromises your independence.
In 1984-5 the then Minister for Transport publicly announced that consideration of future airport sites for Sydney would henceforth be limited (from the larger number considered to that time) to just Badgerys Creek and Wilton. That decision and public announcement clearly put Wilton on the public record as the most feasible alternative to Badgerys Creek. In the opening paragraph of the Summary Draft EIS you acknowledge that "detailed environmental assessments" were done for Badgerys Creek and Wilton, though you elected to not explicitly advise of the formal short-listing of these two sites. But in any event it is clear that Wilton was the prudent and feasible alternative, and that such information was available to your firm at the time of the EIS.
As you know, the government and the 1997 EIS was severely criticised by the government-appointed auditor of the process in the following respects:
[Source: SMEC Auditors Report Jan 1998]
The larger size airport now being considered and the subsequent residential development of Western Sydney has made Wilton even more feasible in the 15 years which have elapsed since its formal equal ranking with Badgerys Creek. Further, as the air quality study promised at the time of the Third Runway EIS was never undertaken by the Federal government, we must rely on overseas information in respect of air quality issues pertaining to aviation. The knowledge gleaned over the past 15 years as to airports and their attendant ground transportation (ie effects considered as a whole) has highlighted that an airport is one of a citys largest point sources of hydrocarbon emissions. This means that an outside-the-basin site is now even more critical than when Badgerys Creek and Wilton were ranked equal 15 years ago. Moreover, your Summary Draft EIS noted "Most respondents expressed the view that the Second Sydney Airport should not be located within the Sydney basin". This desire for an outside-the-basin site reflects a clear change in public opinion since the time of the earlier detailed environmental assessments (refer paragraph 1.3.25 of SMEC Auditors Report). Finally, the decision to have a very fast train route pass right past Wilton is a very pertinent infrastructure decision not known at the time of the 1984-5 studies, and again this knowledge (if it were to be appropriately considered by you) would tip the scale significantly in favour of an outside-the-basin site in the near Southern Highlands.
All of your work on the EIS for Badgerys Creek is to-date silent on the issue of a comparison of Badgerys Creek to Wilton, because the government of the day has instructed you as contractors to not consider Wilton, which is in the middle of the electorate of the Minister for Finance, John Fahey. The peak community group seeks your assurance that the attached comparison (in its entirety) of Badgerys Creek and Wilton will be included in your Summary Supplementary EIS, in accordance with your statutory obligations.
Clearly your work has simplistically compared Badgerys Creek to only a do nothing alternative. Even a patently bad site proposal will compare favourably to the continued expansion of Kingsford-Smith airport. But clearly that is not the question an EIS is intended to address. The question is "Is this site proposed by the proponent the most suitable of all feasible and prudent alternative sites?" In this regard, a few sections of the SMEC Auditors Report are worth noting:
"23.2.1 The key requirements of the EIS Guidelines for the economic aspects were:
The question you address in detail - which runway configuration to use at Badgerys Creek - is only assisting the proponent with its planning. It adds nothing to the fundamental question of whether the project at Badgerys Creek stacks up against prudent and feasible alternatives. You state in the EIS that it is being done in accordance with the Act, yet you have accepted the proponents instructions as to which sites to not consider for comparative analysis. Your analysis to date is analogous to considering only the alternative of people having to keep all human waste inside their homes, when considering a particular sewage treatment works proposal/site. Your earlier work also considered a site at Holsworthy, as instructed by the government, even though this site was only ever ranked 7th of possible sites. But even if that was a lame excuse then (refer SMEC Auditors Report paragraph 1.3.13), once the government ruled out Holsworthy, it made it even more nonsensical for you to fail to consider options the government of the day (indeed particular ministers) would prefer not be considered. It is not as if the relevant material was not available, as comparative work was conducted in the earlier studies. If one simply updated the census data relevant to the respective areas, one would be in a position to update the population impact, which is clearly one of the major determinants. The relative air pollution clearance attributes of both sites has not changed since the analysis of 1984-5 (though the overall level of pollution has) and hence it would be just as valid to republish these facts as to each sites major attributes.
We believe you as the consultants have a moral and professional obligation under the Environment Protection (Impact of Proposals) Act and its Administrative Procedures to consider all feasible and prudent alternatives. Indeed the whole purpose of an EIS is to ensure that such alternatives as the government of the day may not wish to consider are considered, for reasons of public interest. The EIS process is meant to be the primary means of ensuring against governments making unsound environmental decisions. Your actions and printed material available to date paints your organisation as a willing accomplice to the governments defective decision-making process, rather than as a protector of the publics position.
The following summary of major points of differentiation shows that Wilton is a site that any proposal needs to be compared against in a proper EIS. Where there are valid metrics (eg number of people affected, relative hours of travel time), our group agreed to use the ratio of such metrics to derive a relative score for each site. For example with a 1:14 ratio of numbers of people affected, one site received a score of 1/15th of 100, while the other received a score of 14/15ths of 100. As you have not provided current population numbers affected for Wilton in your work, we have used the 1984 figures for relative population levels. Current figures would exacerbate the ratio, showing Badgerys Creek is now significantly more than 14 times worse than Wilton. However, we have used the 1984 figures in the attached analysis. The 1984 study shows Wilton as being only 15km further from the city by rail (assuming the 2015 network). This also may have changed, but without comparative figures, we need to rely on the last work done considering both sites, and have used the figures of 5,000 people-hours travel time for Badgerys versus 7,000 people-hours for Wilton. Since those calculations, the announcement of a Very Fast Train proposal changes this significantly. A VFT may actually deliver a shorter travel time from the CBD to Wilton (compared to the conventional rail track from the CBD to Badgerys). Accordingly, we believe the relative travel time figures of 1984 (as used in our analysis for conservatism) would be far less favourable to Badgerys if now updated to take into account present circumstances and presently proposed infrastructure.
With factors which defy direct metrics, we surveyed the representatives of our constituent group members (representing the whole range of Sydneys airport community groups) to derive values from Excellent (100%), Very Good (80%), Good (60%), Fair(40%) and Poor(20%). This is actually a six-value ranking system, as there was the implicit potential value of no value(0%) even though this was not used. We decided that it was not possible to use any greater precision, yet we believed it was very necessary (due to past/continuing obfuscation) to explicitly score the sites relative merits.
Before making any alterations to our work, please write to us with your opinions or suggested corrections or email them to me at email@example.com. If there is some error of fact, we are more than happy to correct it. However, the attached table must be included in the Summary Supplemental EIS, both because it is the comparative site summary otherwise omitted, and because it represents the final feedback of the peak community group on the issue of the Badgerys Creek EIS.

COMPARISON OF THE TWO HISTORICALLY SHORT-LISTED SITES
BADGERYS CREEK SITE
SOUTH OF WILTON SITE
|Badgerys was rated in 1984 as having fourteenfold the number of people affected as Wilton. Since 1984 residential development has occurred right up to the boundary fence of the proposed site at Badgerys. The EIS predicts a tripling in passenger movements by 2025 requiring expansion of Badgerys Score (inverse proportion to population) 7||Wilton remains relatively undeveloped at the eastern edge of the Southern Highlands. Less than one-fourteenth the number of people would be adversely affected compared to Badgerys. From EIS figures, more people would smell kerosene from Badgerys than would hear planes at Wilton. Worlds best practice is to locate new airports away from people. Score (inverse proportion to population) 93|
|Badgerys is the worst part of the basin, the EIS noting "air currents tend to carry pollutants towards western Sydney, where they can be slow to disperse". By 2020 the airport may have grown from accounting for 5% of Sydneys total hydrocarbon emissions to 8-10%. Score Poor(20)||Wilton is on top of a plateau and has good air dispersion factors (1984 study). Any such outside-the-basin site can relocate at least 5% of Sydneys smog away from 3 million people. Badgerys EIS noted "Most respondents expressed the view that the Second Sydney Airport should not be located within the Sydney basin" Score Very Good(80)|
|48 min by
train & 60-74 min by car to/from CBD. Badgerys is
48km from the CBD by road & 68km by rail assuming the
2015 networks (source 1984 study which also calculated
relative travel times).
Score (inverse proportion to person-hours) 58
71km from the CBD by road. With M5 East due soon, KSA
to/from Wilton connection will be all expressway. 15km
further by rail, but right on Very Fast Train route, so
could be quicker trip than Badgerys!
Score (inverse proportion to person-hours) 42
as KSA Replacement
|Badgerys residents will also deserve a curfew, so Badgerys will eventually be environmentally-constrained like KSA. Extensive night fogs will force planes to land at KSA, effectively removing KSAs curfew. Score Poor(20)||Wilton could support a true 24 hour operation and be an eventual replacement for KSA, for well through the next century. Aviation industry could continue its rapid expansion without this growth always being at the expense of residents. Score Very Good(80)|
Conflict with Other Airports
|Badgerys will close Hoxton Park, conflict with the 500,000 movements/year at Bankstown, and affect Camden. As to KSA, the EIS notes Badgerys will have "significant impact, potentially reducing the capacity of both airports". Badgerys will prevent noise-sharing modes at KSA. Score Fair(40)||Wilton will not have any substantial impact on any Sydney basin airports (affecting only Camden) and would allow independent operation of the two major airports (ie any mix of modes at KSA to be used at any time). Planes using Wilton need never fly over any part of the greater Sydney metropolitan area. Score Good(60)|
|Employment Effects||Sydneys job-hungry West and SW suburbs would be the main job beneficiaries of the construction and operation of Badgerys. Score Excellent(100)||Sydneys equally job-hungry South-West corridor (Liverpool to Campbelltown) would be the main job beneficiaries of an airport at Wilton Score Excellent(100)|
|1984 study put site work at $94m. Tens of millions spent on land acquisition to date could be recouped by selling site for residential development.||1984 study put site work at $103m (ie only $9m more than Badgerys in overall $3-4b project). Wilton has far lower total land acquisition and subsequent expansion costs.|
|Costs Road||Badgerys would require a new expressway (as proposed by the government) to link it to KSA.||Wilton is only 3km from existing SW Freeway which is currently being extended (M5 East) to directly link KSA.|
|Costs Rail||Badgerys would need a new rail line (optional in EIS) connecting the Western line via Badgerys to the Macarthur line. The trip to the CBD would be circuitous, with suburban track most of the way.||Wilton has an existing rail line crossing the site, and is only a few kilometres from the proposed Very Fast Train line to connect Sydney to Canberra, thereby affording the opportunity of high speed rail access.|
requires slightly less earthworks on site, but has far
higher value land tied up/impacted and requires more new
infrastructure (road & rail).
Overall Cost: Fair(40)
|Wilton requires slightly more earthworks, but far less in acquisition costs (being non-residential land) and far far less in new road and rail infrastructure (being located right on existing infrastructure corridor).Overall Cost: Fair(40)|
/Suitability of Site
|Badgerys will suffer windshear in winter, with SW and West winds blowing over the Blue Mountains causing disturbance. Rising land beyond each end of proposed runways (Horsley Park escarpment is much higher than runway) adds crash risk. EIS notes 2,500 residents above EPA-approved risk.||Wilton has some river gullies within 10km but any turbulence in strong winds would be limited to a very low near-ground effect. No "Blue Mountains crash risk". Likely number of fog/poor visibility days far lower than Badgerys Creek adding to overall safety, as well as operation away from mountains and other airports.|
|Safety Fuel Transport||Unless a new fuel pipeline is built (proposed), Badgerys will require fuel to be transported by road on the F4 or by rail on the suburban network.||Wilton has existing rail route allowing fuel to be transported from Shellharbour through primarily uninhabited bush areas. New pipeline also just as viable.|
|Safety Crash Risk to Infra-structure||A crash could not only kill a larger number of residents than at Wilton, but could also disable Sydneys water supply or electricity grid (critical components of Sydneys water, electricity and gas supply being very close). Overall Safety: Poor(20)||A crash at Wilton would affect primarily bush and farmland. Gas pipeline risk is same. One open creek feed (downstream of dam) may need to be converted to a pipeline, but this affects less than 20% of Sydneys water supply capability. Overall Safety: Very Good(80)|
Grand Total Score 305
Grand Total Score 575 (88% above Badgerys)
