This application concerned consent for chlorine levels to be reduced on the site. A letter from then works manager Clive Platts outlines the scenario below.
A modified location plan is shown below.
It was submitted on 29/10/93 and a decision for approval issued on 17/2/94 by The Black Country Development Corporation. Phosphine quantity remained unchanged on site.
With the demise of the rail carrying method for chlorine and introduction of road carrying and in an apparent trade off deal with the Black Country Development Corporation who loaned them the money, the exclusion zone around the works was reduced to 750 metres.
This enabled more housing developments to take place and Albright and Wilson applied for a substantial reduction in the amount of chlorine that it handled at the works from 720 tonnes to a maximum 50 tonnes. Though the amount may have reduced in this purely business inspired deal, the hazard of spill by road tanker did not diminish the risk.
