16 Tex. Admin. Code § 12.513 - Hydrologic Balance: Sediment Control Measures
(a) Appropriate sediment control measures
shall be designed, constructed, and maintained using the best technology
currently available to:
(1) prevent, to the
extent possible, additional contributions of sediment to streamflow or to
runoff outside the permit area;
(2)
meet the more stringent of applicable state or federal effluent limitations;
and
(3) minimize erosion to the
extent possible.
(b)
Sediment control measures include practices carried out within and adjacent to
the disturbed area. The sedimentation storage capacity of practices in and
downstream from the disturbed areas shall reflect the degree to which
successful mining and reclamation techniques are applied to reduce erosion and
control sediment. Sediment control measures consist of the utilization of
proper mining and reclamation methods and sediment control practices, singly or
in combination. Sediment control methods include, but are not limited to:
(1) disturbing the smallest practicable area
at any one time during the mining operation through progressive backfilling,
grading, and prompt revegetation as required in §
12.555(b) of
this title (relating to Revegetation: General Requirements);
(2) stabilizing the backfilled material to
promote a reduction of the rate and volume of runoff in accordance with the
requirements of §
12.551 of this title (relating to
Backfilling and Grading: General Requirements);
(3) retaining sediment within disturbed
areas;
(4) diverting runoff away
from disturbed areas;
(5) diverting
runoff using protected channels or pipes through disturbed areas so as not to
cause additional erosion;
(6) using
straw dikes, riprap, check dams, mulches, vegetative sediment filters, dugout
ponds, and other measures that reduce overland-flow velocity, reduce runoff
volume, or trap sediment;
(7)
treating with chemicals; and
(8)
treating mine drainage in underground sumps.
