Left coal production in the vicinity (5)
I believe the answer is:
local
'in the vicinity' is the definition.
(I've seen this in another clue)
'left coal production' is the wordplay.
'left' becomes 'l' (common abbreviation).
'production' indicates an anagram.
'coal' with letters rearranged gives 'ocal'.
'l'+'ocal'='LOCAL'
(Other definitions for local that I've seen before include "hearing" , "(Pub) of the district" , "Parish pump" , "Pub - of a particular area" , "Confined to the home area" .)
