Kingston's coal gasification plant operated within a two-block area of the City's downtown from the mid 1800's through to the 1950's. The coal tar produced by the plant was stored within the bottoms of large "gas holders" that had been excavated right into the limestone bedrock. It is not known where all the coal tar produced by the plant ended up.
