The British Geological Survey (BGS) was commissioned by the CBI Minerals
Committee and the Quarry Products Association (QPA) to study the impact of Civil
Aviation Authority (CAA) safeguard zones upon the river sand and gravel resources of
the Trent Valley Gravel Resource Zone. The results indicate that safeguard zones cover
nearly 76% of the potentially workable sand and gravel resources in the Trent Valley,
with 66% of allocated sites and 42% of sites with planning permission also covered by
safeguard zones.
The CAA safeguard zones in the Trent Valley would therefore have a significant impact
on sand and gravel operations in this area, with up to three quarters of all sand and
gravel resources being potentially sterilised by these zones
