Devon reserves

Devon sand and gravel production figures in million tonnes (Mt); estimated from 2017 onwards.

Devon's sand and gravel reserves at the end of 2016 were 7.04Mt, according to DCC.

The 10 year average, as detailed in DCC's Local Aggregate Assessment, is 0.527Mt which gives a landbank of 7.04 / 0.527 = 13.4 years.

DCC's Minerals Plan will run a further 17 years until 2033. Using the 10 year average figure of 0.527Mt, there is a potential shortfall of sand and gravel over the Plan period of (17 x 0.527) - 7.04 = 1.9Mt
