310 CMR 30.632
Stabilization/Solidification Plan
(1) The owner or operator shall prepare a stabilization/solidification plan designed to ensure
that all wastes disposed of in the landfill have been treated to the maximum extent practicable
to minimize the potential for wastes migrating from the landfill site. At a minimum, the
stabilization/solidification plan shall specify:
(a) The wastes which will be stabilized and/or solidified at the landfill site prior to disposal;
(b) The techniques which will be used to limit the solubility and potential for migration of
the waste by:
1. The addition of materials that ensure that hazardous constituents are maintained in
their least soluble form;
2. The production of monolithic blocks of treated waste with high structural integrity;
and/or
3.
The placing of a jacket or membrane of material of low permeability and low
chemical reactivity between the waste and the landfill;
(c)
The means that will be used to ensure that wastes which will not be stabilized or
solidified at the landfill site will, to the maximum extent practicable, be stabilized or
solidified at the site of generation of the waste, or at another facility where such stabilization
or solidification can be lawfully done, if the landfill is not at the site of generation of the
waste;
(d) A description of the physical and chemical properties of the stabilized/solidified waste
(e.g., compressive strength, leachability); and
(e) A quality assurance program designed to ensure that the stabilized/solidified waste
meets the specifications which are outlined in the stabilization/solidification plan.
(2) The stabilization/solidification plan shall be submitted to the Department with the license
application and upon approval by the Department shall become a condition of the license.
