A number of photomontages have been produced to give people a “reasonable representation” of how the proposed Weston Option cement plant would look from various viewpoints around 15 – 20 years after establishment.
Modelling has shown that the plant would not be visible from either the Oamaru or Weston townships. The top of the 104 metre high main stack would be 172m above sea level, which would actually be lower than the height of the escarpment immediately behind the plant site and to the east, which ranges from 173 to 185 above sea level.
The discharge of water vapour can, in certain atmospheric conditions and depending on the moisture content of the raw materials, result in a visible plume. On clear sunny days, such as shown in these photomontages, it is unlikely that there would be a visible plume of water vapour.
