CHANGES CAUSED BY NOISE, IN NORMAL CONDITIONS AND IN<br />

CASE OF ECOLOGICAL EMERGENCY<br />

On the container terminal container reloading activities will be carried out.<br />

These activities are not accompanied by additional air pollution, as it is the<br />

case with bulk or loose freight. Potential sources <strong>of</strong> the air pollution are:<br />

• Berthed ships<br />

• Heavy road cargo vehicles (trucks)<br />

Ship’s main engines usually do not operate when ship is moored, and<br />

emissions generated by auxiliary engines are insignificant.<br />

The trucks reloading cargo in the reloading area may be a source <strong>of</strong> additional<br />

air pollution, depending on the gasoline used and on how old the engines are<br />

and how well they are maintained.<br />

Nevertheless, due to the distance, the impact upon the settlements <strong>of</strong> Ploce is<br />

insignificant.<br />

In order to reduce the negative impact <strong>of</strong> the trans<strong>port</strong> means on air quality,<br />

the cargo vehicles on the terminal have to meet the requirements <strong>of</strong> the new<br />

EURO II and EURO III standards.<br />

In general, the changes <strong>of</strong> the <strong>port</strong> morphology generate changes in seawater<br />

quality.<br />

The planned construction may primarily affect the sea currents, the water<br />

body dynamic and time for the water exchange in the entire <strong>port</strong>. A potential<br />

key problem may be a decreased water flow and the water exchange with the<br />

surrounding aquatorium. Weak flows and retarded exchange <strong>of</strong> the water<br />

loaded with organic matter and nutrient salts may increase the concentration<br />

<strong>of</strong> these substances and the growth <strong>of</strong> the algae and consequently cause a<br />

decrease in the oxygen concentration and further turbidity. This may result in<br />

complete lack <strong>of</strong> oxygen and development <strong>of</strong> anaerobic organic matter<br />

decomposition, which produces unpleasant odor and is toxic for many sea<br />

organisms. One may say that such is the present situation in the basin<br />

between Quay 5 and Quay 7.<br />

Proposed is also an extension <strong>of</strong> the basin between Quay 5 and the future<br />

Quay 7, which would in fact be a correction and extension <strong>of</strong> the existing<br />

basin that is currently too narrow for the estimated number <strong>of</strong> container ships.<br />

The operation will have a positive impact on the water exchange both in the<br />

<strong>port</strong> aquatorium and its surrounding.<br />
