Materials produced at a rate below third party rates for primary source materials. Large quantities of soft (Class 1 fill) produced. Blackman Plantation (North) Stockpiling to commence Looking to undertake a crush in late Past programmes have identified that sub-bases will be required in the vicinity of this location. Due to limited space only hard materials to be stockpiled. Wombleton Significant quantities of materials in store which could be crushed. Past programmes have identified that sub-bases will be required in the vicinity of this location. Planning approval unsuccessful, one-off crush and screen being considered for materials stored there.
