43.90(f)(1) •
(1) Even when constituents meet all three tests in the definition of
• hazardous constituent, the Agency may exclude a detected consti-
tuent from the set of hazardous constituents on a site-specific
basis if it finds that the constituent is not capable of posing a
substantial present or potential hazard to human health or the
environment. In deciding whether to exclude constituents, the
Agency will consider the following:
(i) Potential adverse effects on groundwater quality,
considering the:
(a) physical and chemical characteristics of the waste in
the licensed site, including its potential for migra-
tion;
(b) hydrogeological characteristics of the licensed site
and surrounding land;
Cc) quantity of groundwater and the direction of ground-
water flow;
(d) proximity of groundwater users and groundwater with-
drawal rates;
(e) current and future uses of groundwater in the area;
• (f) existing quality of groundwater, including other
sources of contamination and cumulative impact on the
groundwater quality;
(~) potential for hutaan health risks;
(h) potential damage to wildlife, crops, vegetation, and
physical structures; and
(i) persistence of potential adverse effects.
(ii) Potential adverse effects on quality of hydraulically-
connected surface water, considering the:
(a) volume and physical and chemical characteristics of the
byproduct material in the licensed site;
(b) hydrogeological characteristics of the licensed site
and surrounding land;
(c) quantity and quality of groundwater and the direction
of groundwater flow;
(d) patterns of rainfall in the region;
(e) proximity of the licensed site to surface waters;
