The THA is investigating whether one of its own vehicles was involved in the improper handling of white waste in Tobago.
The Division of Infrastructure, Quarries and the Environment says a vehicle bearing the mark of the THA was seen to be involved, at Bird of Paradise Drive.
It says the site in question is the Grange Quarry owned by THA used as temporary storage for backfill material.
The Division such actions as reported were unsanctioned and it does not condone improper waste disposal or illegal dumping.
Management is assuring the public that anyone found in breach of the environmental laws will be treated with accordingly.
