CHANNEL DEEPENING

support Earthcare in its endeavours to persuade the government that the
channel deepening of Port Phillip Bay is not good for the environment. |

PROTECTING OUR PRECIOUS ENVIRONMENT IS THE MOST IMPORTANT THING. |
|
| "Protecting
our precious environment is the most important thing" say both John
Thwaites and Tim Holding (Jan 10th and Jan 12th). They are both correct.
It is.
The decision-makers now need to have a clear, detached look at the environmental facts before them. They will see that the project cannot "be achieved in an environmentally responsible way" and so must not be allowed to go ahead. First they need to acknowledge that the Environmental Effects Statement (EES) is fundamentally flawed. The Port of Melbourne Corporation and the Labor Government, who are both in favor of the channel deepening, paid for the Environmental Effects Statement. This kind of funding structure is well known to inevitably bias results. Consultants and editors frequently interpret 'study findings' with a bias towards results that the funding body likes to hear. Less palatable information tends to be glossed over or simply not mentioned. The government needs to read the EES with this in mind. It needs to look beyond the editorial summaries to the hard environmental facts. Then it will see a very different picture: The proposed channel
deepening is massive in its scale. It involves the removal of forty million
cubic metres of sand, clay and rock from the seabed and ongoing dredging
operations. This will inevitably increase the turbidity (murkiness) of
the water over significant areas of the Bay. Light will not be able to
penetrate through murky water. Aquatic plants (the basis of the food chain)
that rely on light will die. Animals that depend on these plants will
slowly starve to death. As little penguins
are near the top of the food chain, they are a key "indicator"
species for the Bay. Their fate is representative of the fate of the ecosystem
as a whole. The project will weaken the Phillip Island penguin colony
as a significant number of Phillip Island penguins feed in Port Phillip
Bay during winter to attain breeding condition. If the penguins don't starve to death they may be poisoned to death. Toxins and heavy metals are also a major concern. Toxic sediments, in excess of three million tonnes will be disturbed by the dredge. The toxins released will include lead, mercury, TBT and DDT (2). Marine animals accumulate these toxins and pass them up the food chain. The bay currently processes the nutrients discharged from the Werribee sewerage treatment plant, and stormwater run-off from the Yarra River. The capacity of the bay to handle these nutrients will be disrupted by the project. The increased nutrient levels will risk toxic algal blooms. It was with this in mind that CSIRO "categorically recommended that dredging be minimized" (2). If the penguins are not starved or poisoned to death, then an oil spill will make certain their fate. The passage through the Port Phillip Heads, with its "high turbulent flow with large eddies" (3) is a difficult and dangerous one. If ships with a draught over 12 metres are allowed through, the risk of ships running aground will increase significantly. In their own computer modelling the Port of Melbourne Corporation had 10% of its ships running aground (4). Were an oil tanker to run aground at the Port Phillip Heads, the consequent oil-spill would be an environmental, economic and social disaster. "Cause of death"
is commonly assigned to one particular reason. But it is generally understood
that a combination of debilitating circumstances often contribute to the
demise of an animal, an ecosystem, a lifestyle, or even a government.
If the proposed channel deepening goes ahead, Port Phillip Bay might present a very different picture: beaches closed due to toxic algal blooms. Penguins belly up on the beach. The remaining fish no longer safe to eat. The sea coated in oil and The Heads a ship's graveyard. You and I, and the Victorian economy any better off? I doubt it. Any project that risks this kind of environmental devastation cannot be considered "environmentally responsible". Alternatives must be reconsidered.

Bay: Connecting Mammas with Mammals!
A Current Affair has
agreed to cover the story!! For those of you who don't know about it,
I have attached a copy of my press release. I have also sent press releases
to The Age, the Herald Sun and Melbourne Weekly magazine. Save Our Bay: Connecting
Mammas with Mammals! |

PORT PHILLIP BAY CHANNEL DEEPENING.WHAT IN IT FOR YOU? - "IT'S IMMEASURABLY MINOR!"The Port of Melbourne Corporation (PoMC) is asking Victorians to sanction a range of environmental, social and economic risks, so that just some of the world's supersized container vessels and larger oil tankers can enter the Bay fully loaded. The Southern waters of Australia, including Port Phillip Bay has the highest diversity of marine species anywhere in the world. 90% of species occur NOWHERE else on earth! Many of those species have not even been fully studied - and yet, before we understand our beautiful local underwater world, we might lose it. Scope of the Channel Deepening Proposal: 40 + million cubic
metres (40,000,000 tonnes) of sand, silt from the sea bed of Port Phillip
Bay and the Yarra River, and rock removal by intense hydro-hammering from
the The Rip. Noise levels still not available for hydrohammer. What is at stake? ... The EES acknowledges that the variety and interdependence of the 5000 species in the Bay is not yet fully understood. This lack of knowledge poses the greatest threat to the marine ecosystem of Port Phillip Bay. Here are some of the serious threats: Increased turbidity
- Death of species reliant on sight for location of food: some fish, dolphins,
seals, penguins, etc. This project is purely about moving boxes around the Nation It is a logistics
puzzle, not complex science and So - What is the alternative? Presently, only 30%
of ships cannot fully load - but 70% can! Supersized ships could offload
their excess at an existing NATURAL deepwater port -Brisbane, Sydney,
Fremantle, Darwin - all connected to the National standard gauge rail
What can we do? And can the Federal Government assist? YES! The project has been referred to the Federal Government under the Environment Protection and Biodiversity Conservation Act 1999, due to matters of National significance: Marine Parks, RAMSAR sites and Commonwealth land (Pt. Nepean and Pt. Wilson) around the Bay. The Federal Government is the final arbiter - so to protect our No. 1 public asset, the Federal government must invoke its undoubted powers under the EPBC Act to ensure this destruction does not occur! Write now to the Federal Environment Minister Sen. Ian Campbell -see formletter on website below. Use the above information
to also write to Premier Steve Bracks, Ministers Peter Batchelor (Ports),
John Thwaites (Environment), Mary Delahunty (Planning) firstname.surname@parliament.vic.gov.au
and your local state & federal MP's. |
