Dear Forum Members
Please find attached the first issue of JISCmail GACs to plug the hole left by
the Agency when they only published SGVs for 6% SOM. We have added
GACs for 1% & 3% SOM and GACs for residential use without plant uptake.
The values for BTEX, inorganic mercury & selenium were produced by a group
of volunteers including:
Jason Bale - Cardiff Council
Adam Czarnecki - VertaseFLI Limited
Catherine Helm - WD Environmental Limited
Tanya Holdsworth - T&P Regeneration Limited
Aamer Raza - Harrison Group Environmental Limited
The remainder wished to remain anonymous.
We have adopted the same approach that the Agency used in generating their
SGVs for 6% SOM. Our calculation of these values in no way endorses the
Agency approach to CLEA or their method to calculate SGVs. We have been
sensible with rounding and followed a similar approach the Agency adopted at
6% SOM (typically rounding to two significant figures).
We have provided a single value for xylenes (based on lowest isomer values)
which we suggest should be compared against the sum of xylene isomers
We are all professionals on here, so I’m not going to add a long list of
consultant speak caveats: you all know the score, so please use them
appropriately.
Kind regards
Chris Dainton on behalf of the JISCmail GAC volunteers
