DEFRA have formally withdrawn ICRCL 59/83 (2nd edition).
And life has suddenly become even more interesting for everyone.
This extract from Brownfield Briefing gives a bit more detail:
"DEFRA withdraws health guidance
DEFRA has formally withdrawn its 1987 guidance on health effects of contaminated land – including the “trigger values” rendered obsolete by the Part IIA regime – following the implementation of the CLEA package last year.
Steven Griffiths of DEFRA’s Contaminated Land Branch has written to a wide range of representative organisations and local authorities to warn them of the move. He says the ICRCL Guidance Note 59/83 (2nd edition) is now formally withdrawn, although it will remain available from the Department on request to enable understanding of historical decisions on remediation of individual sites.
“The CLEA package, consisting of the main contaminated land reports (CLRs) 7-10, the CLEA 2002 software and the soil guideline values for individual substances (SGV), are now considered to represent the key instruments for generic assessment of the human health risks from land contamination,” says Mr Griffiths. “They represent a cross-government consensus on the technical approach to undertaking such assessments and are based on the latest scientific knowledge and thinking.”
He says the trigger values contained in ICRCL 59/83 were a useful tool but are technically out of date. They are out of line with Part IIA, especially for assessing the “possibility of significant harm” to health. SGVs cover a broadly similar, and widening, range of contaminants."
