314 CMR 5.11 - Ground Water Standards
(1) Except as
otherwise provided in 314 CMR 5.11(2), or unless the Department determines that
the ground water is not an underground source of drinking water as provided in
314 CMR
5.10(9)(c), all ground
waters of the Commonwealth are designated as a source of potable water supply
and the minimum criteria applicable to all ground waters of the Commonwealth
shall be the effluent limitations set forth in
314 CMR 5.10(3)(a) and
(b).
(2) The ground waters classified as Class III
Ground Waters prior to March 20, 2009 are designated for uses other than a
source of potable water supply. At a minimum, the most sensitive use of these
ground waters shall be as a source of non-potable water which may come in
contact with, but is not ingested by humans. The minimum criteria applicable to
such ground waters shall be the effluent limitations set forth in
314 CMR 5.10(3)(a) and
(b) as modified by
314 CMR
5.10(3)(c).
(3) To prevent the ground waters classified
as Class III Ground Waters prior to March 20, 2009 from being further degraded,
the Department may require that any discharge to such ground waters not
authorized by a permit issued by the Department prior to March 20, 2009, and
any increase in the volume or amount of pollutants above that authorized by a
permit issued by the Department prior to March 20, 2009 to such waters, meet
the more stringent of the water quality based effluent limitations and the
technology based effluent limitations set forth in
314 CMR 5.10(3)(a) and (b), and
(4). Alternatively, the Department may
require the discharge to meet the special effluent limitations set forth in
314 CMR
5.10(9), if the permittee
requests such limitations and makes the required demonstrations.
