Hi Matt
There is a very detailed process to be followed for assessing relevant
H1-H14 hazards and you should ensure that the up-front testwork takes
consideration of the assessment required. For instance, you need to make
sure you analyse for the correct PRO / DRO split, the presence of
lubricants and so on. here is extensive guidance on this issued by the
EA titled WM2. you should find it at:
http://www.environment-agency.gov.uk/subjects/waste/1019330/1217981/1384
307/
You say that you have determined the material to have an absolute non
hazardous entry. If this is correct then there is no need to assess for
hazardous properties H1-H14 as the material is classified as
non-hazardous according to EWC. I would however be careful as you can
not be sure what is in the embankment. You would probably therefore
want to treat it as a mirror entry to start with e.g. 17 05 03.
You could potentially avoid going down this route all together if the
material is not waste and is going to stay on the same site for re-use.
Hope this helps.

Subject: Hazardous Waste Regs
I was wondering whether anyone can help me out! I have a site which
consists of a railway embankment believed to have been constructed of
ironworks waste in the 1890s (i.e. unprocessed slags). The EWC codes
class
the waste as 'non-hazardous' and it is neither an 'absolute' nor a
'mirror' entry.
I will shortly be commissioning a ground investigation to generate
chemical
data for the waste subject to it being reused as bank stabilisation
material (so
long as it is 'suitable for use'). The objective of the soil and
leachate sampling
will be to prove that the material is non-hazardous, as the EWC code I
have
arrived at is based on anecdotal evidence (even though there is a strong
weight of evidence to suggest that the waste is unprocessed slag).
My question is - once I have my chemical analysis results back, does
anyone
know how to determine whether the waste (on account of its properties)
qualifies as a H1-H14 hazardous material? (or even if this matters given
that
the waste class is neither an 'absolute' nor a 'mirror' entry) If it
does matter,
are there threshold concentrations available in some
publication/guidance
document above which the waste is classified as, for example, toxic or
corrosive?
