Clay and Brickearth Extraction
13.27 Extraction of clay and brickearth for the production of building products ceased many years ago
and is unlikely to resume. Proposals do arise however to use such material for civil engineering works such
as motorway embankments. The working of such 'borrow' pits can assist in providing a source of material
close to the works site and may consequently reduce traffic generation. They are normally worked against
a tight timescale unrelated to the normal method of operation of sand and gravel pits and this can present
significant technical difficulties, particularly involving more double handling of top and sub-soils and
working in weather conditions unsuited to the application of best restoration practice. The frequent lack of
management continuity, with one contractor carrying out excavation and another carrying out landfill
restoration, also presents problems in securing a high standard and identifying responsibility for five years
successful aftercare in circumstances where the management chain has been disrupted.
13.28 Brickearth sub-soils are necessary for successful restoration and should be conserved where the
underlying clays are worked. The primary objective is to balance the potential short-term traffic reduction
benefits from the use of 'borrow' pits against the potential for long-term creation of damaged or derelict
land when the operation inherently lacks the continuity normally applying to the restoration of sand and
gravel workings.

THE IMPORTANCE OF THE PROJECT, THE DEMONSTRATED NEED FOR THE
MATERIALS AND LACK OF SUITABLE ALTERNATIVE RESOURCES OR DESIGN
SOLUTIONS WITHIN THE NECESSARY TIMESCALE;
THE ADEQUACY OF THE APPLICANTS' PROPOSALS FOR LIMITING THE
OVERALL TIMESCALE OF THE OPERATION, TOGETHER WITH
ENVIRONMENTALLY ACCEPTABLE PROPOSALS FOR EXTRACTION,
LANDFILLING (WHERE NECESSARY), RESTORATION AND AFTERCARE OF THE
SITE AND HOW THE APPLICANT WILL MANAGE THE SITE DURING EACH
PHASE;
