Not used to

Not Considered
as a constraint
to landfill
capacity
Used to set
authorisation
conditions for
leachate
discharge
Not used as a
constraint on
landfill capacity
because worst
case constraint
is larger than the
physical landfill
Not used as a
constraint on
landfill capacity
or leachate
discharge
concentration
because the
case in section
8.6 is more
constraining
Considered as a
potential
constraint to
landfill capacity
