Eroded soil can be deposited in water courses and on roads and other infrastructure, leading to a loss of agricultural soils to landfill. PAS 115:2021 sets out how to treat road sweepings and inert gully waste so it can generate soil and soil amendments and keep materials out of landfill.
It specifies requirements for the generation of soils and soil amendments through treatment of road sweepings and inert gully waste. It covers requirements for the sorting of material type, size, and quality, including levels of fertility, for the purpose of future use as soils.
It defines requirements for a Quality Management System (QMS) for the generation of soils and soil amendments. It also requires a Safety and Quality Control System, including Hazard Analysis and Critical Control Point (HACCP) assessment, which the user considers takes into account when developing, implementing and reviewing the QMS.
PAS 115:2021 also adopts a process of Hazard Assessment for the types of pollutant that can beis encountered in road gully and road sweepings. The PAS process defines CCP to maximize the possibility that the levels of the specified pollutants if used as the sole component for a soil, present no significant risk linked to the specified pollutants on the types of plants or users of the land in which they are grown.
