I would have thought your right to be concerned but if they can reuse the material I would regard that as generally being beneficial.
The biggest barrier to reused would normally be the structural properties of the material... so they must be pretty keen have they done a P20 risk assessment to water.. have they adequately explained to you and the agency why this is not a problem have they passed on the p20...
will they pay for someone to look at the risk assessment.
you can probably get a second opinion from somebody on the list for less than £1,000 the cost saving for the developer are huge.. a second look at the assessment could be money well spent...
I often get my ruffled feathers soothed by an external source it just gives you something to hang your hat on.
So much to read.

Subject: Movement of ashy Made ground and leachability of metals/ PAH's
etc.
Happy New Year to everyone,
I wonder if anyone can advise me further here.
We have a very large dveleopment site which is going to be Olympic
style sports facilities including indoor and outdoor pitches, olympic
pool etc.
An application is in and the design of the scheme invloves removing
large amounts of ashy/ clinkery type Made Ground/ ashy soils etc. from
one part of the site to another in order to build up levels. The
materials in-situ are from the old gas works and have shown to be not
significantly impacting the groundwater.
I have raised my concerns that excavation of materials wil increase
surface area/ porosity/ environmenatl situation of the materials and
that contaminants in the materials may increase thire leachability and
impact the grouindwater more significantly.
However, the Consultant argues that the leachability tests on the
material represent the most severe situations and the worst case
scenario as the smaples are agitated etc. However, I remain sceptical
about this and would like to see post removal/ post development
monitoring to demonstarte compliance with approved remedial targets.
Have I got a point? Or, am I being overly cautious. To be honest, it is
such a lot of material that is being moved and not so many leachate
samples. Also, I'm not so offay with the efficacy of leacability
testing.
Many thanks,
Clare.
