Just a thought - would it be advantageous for a motion to be put to the CLEA
team to produce tox reports in lieu of SGV values. I think the general
consensus is that the SGV's have very limited use, however the tox reports
may allow us to undertake site specific risk assessments. The SGV reports
are every detailed and obviously a lot of work goes into their production.
Maybe this can be diverted into the production of tox reports.
Having reviewed the variation in 1% SOM results of the current workbook for
all land uses based on the most conservative parameters (land use type and
soil), compared to previous threshold values, there is a massive potential
for 'unnecessary' disposal of soils which may be considered suitable in the
next few months/year. Considering the current economic climate this could
make or break many developments currently being moth balled or the the edge
of viability.
Would it also be prudent, considering the revised concentrations which
appear to be suitable for use, to have acute thresholds also noted on the
risk assessment.
