• A key aspect of the quarry is both its compliance with the various legislative requirements involved in running a quarry, and high quality of the products it provides Both considerations feature in the vision and objectives; and • It is also important that the quarry is financially sustainable into the longer term To thisFirst, it facilitates the filling and reuse of spent (or abandoned) quarries, sand pits and gravel pits These locations are often safety hazards and their reclamation can provide opportunities for beneficial new uses, including parks Second, it provides increased instate options for the reuse of soil excavated from new development projects"Reclamation Soils" Policy and Facilities Massgov
