It is clear from the passage that the events described in the passage amount to a "success story" ----.

The people of Blaenavon in South Wales were
understandably worried. The opencast mine only 1
kilometer north of their town had served the great
Blaenavon ironworks when they opened in the
Iate18"1 century. But it had been lying derelict for
decades and now British Coal Opencast wanted to
mine the remaining 320,000 tonnes of coal. At
opencast sites, for every tonne of coal recovered, up
to 40 tonnes of rock has to be extracted. So, in the
case of Blaenavon, unless precautionary measures
were taken, the air in the town was going to be thick
with dust. Precautionary measures were taken,
based on well-tried techniques. For instance, tall
spray masts were erected around dumps to provide
a curtain of rain to entrap and wash out dust from the
air, and the wheels of every vehicle leaving the site
were washed. Further, reclaimed areas were planted
with trees and grass from day one. With these and
other measures this turned out to be a success story
for all concerned. In fact, during the entire mining and
reclamation project not a single complaint about
nuisance dust was made to the local authority.
