310 CMR 30.652
Treatment Program
(1) An owner or operator subject to 310 CMR 30.650 shall establish a land treatment program
that is designed to ensure that hazardous constituents placed in or on the treatment zone are
degraded, transformed, or immobilized within the treatment zone. The licensee shall persuade
the Department that:
(a)
The wastes are capable of being treated at the land treatment unit based on a
demonstration pursuant to 310 CMR 30.653;
(b) Design measures and operating practices will be implemented to maximize the success
of degradation, transformation, and immobilization processes in the treatment zone in
accordance with 310 CMR 30.654;
(c)
Unsaturated zone monitoring provisions will meet the requirements of 310 CMR
30.655;
(d) All wastes which are to be treated at the facility are comprised primarily of constituents
that are degradable or transformable in a soil media, and the primary mechanisms of land
treatment at the unit are not immobilization or volatilization of wastes;
(e) The land treatment of hazardous waste will not present a significant risk to public health,
safety or welfare or the environment.
(2) The Department shall specify in the facility license the hazardous constituents that shall be
degraded, transformed or immobilized pursuant to 310 CMR 30.650.
Such hazardous
constituents shall be constituents identified in 310 CMR 30.160 that are reasonably expected to
be in, or derived from, waste placed in the treatment zone.
(3) The Department shall specify in the facility license the vertical and horizontal dimensions
of the treatment zone. The treatment zone shall consist of soils which meet the criteria for the
following United States Department of Agriculture soil texture classes: sandy loam, fine sandy
loam, loam, very fine silt, silt, silt loam, clay loam, silty clay loam, sandy clay and silty clay. The
maximum depth of the treatment zone shall be:
(a) No more than 1.5 meters from the initial soil surface; and
(b) At least four feet above the probable high groundwater level as determined pursuant to
310 CMR 30.675.
