Left coal production in the vicinity (5)
I believe the answer is:
local
'in the vicinity' is the definition.
(I've seen this before)
'left coal production' is the wordplay.
'left' becomes 'l' (common abbreviation).
'production' is an anagram indicator.
'coal' is an anagram of '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" .)
