The National Planning Policy Framework (March 2012) brought in a requirement for all Mineral Planning Authorities to prepare an annual Local Aggregate Assessment (LAA). LAAs are to be based on a rolling average of 10 years sales data and other relevant local information, and an assessment of all supply options. The LAA establishes the provision to be made for aggregate supply in Mineral Local Plans.
This guidance has been prepared jointly by the POS Minerals & Waste Forum with the Mineral Products Association. Its purpose is to provide advice on how to prepare an LAA, and on their use, and it includes examples of practice. It sets out information that should be included in an LAA, including what 'other relevant local information' may be appropriate, and the possible circumstances in which this may indicate a need to deviate from the 10 year sales average. This guidance is principally intended for Mineral Planning Authorities, to assist them in their preparation of LAAs, but also for Aggregate Working Parties in their role as consultees on LAAs.
