The Soil and Groundwater Technology Association (SAGTA) has announced it will be supporting the next phase of Category 4 Screening Level (C4SL) development by inviting industry professionals to join a dedicated C4SL2 steering group.
C4SLs consist of estimates of contaminant concentrations in soil that are considered to present an “acceptable” level of risk, within the context of Part 2A of the Environmental Protection Act (1990).
The new steering group will be dedicated to providing oversight and driving the development of the C4SL initiative.
SAGTA, an association of UK landowners which manages land contamination issues, has invited a number of organisations to join the new steering group in a bid to derive more C4SLs for approximately 50 further compounds. The aim is to freely disseminate this information to industry.
The investment from industry bodies will support the necessary toxicological study works and also allow for a dedicated project manager whose role will be to link the steering group and the C4SL production team. This coordinated approach will drive the development of this initiative and achieve the delivery of further C4SLs.
The steering group will be led by Richard Boyle. He said: “Since the publication of the C4SL work, the scope for their potential use has been clarified by DEFRA, DCLG and the Welsh Assembly. This has confirmed that C4SLs can serve within the planning process as a measure of suitable of use. We accept the existing policy direction and want to progress the initiative on this basis.”
Some preliminary work has already been commissioned including “specifications” that draw out the essential toxicology and exposure elements from the existing C4SL framework in order to ensure the standard and consistency of C4SL production.
SAGTA chairman Frank Evans added his support: “The first batch of C4SL work has made a real difference to our sector. We want to build on the positive work from the industry to date, and are looking forward to supporting the next stage.”
