230.73—Actions affecting the method of dispersion.
The effects of a discharge can be minimized by the manner in which it is dispersed, such as:
(a)
Where environmentally desirable, distributing the dredged material widely in a thin layer at the disposal site to maintain natural substrate contours and elevation;
(b)
Orienting a dredged or fill material mound to minimize undesirable obstruction to the water current or circulation pattern, and utilizing natural bottom contours to minimize the size of the mound;
(c)
Using silt screens or other appropriate methods to confine suspended particulate/turbidity to a small area where settling or removal can occur;
(e)
Minimizing water column turbidity by using a submerged diffuser system. A similar effect can be accomplished by submerging pipeline discharges or otherwise releasing materials near the bottom;
(f)
Selecting sites or managing discharges to confine and minimize the release of suspended particulates to give decreased turbidity levels and to maintain light penetration for organisms;
(g)
Setting limitations on the amount of material to be discharged per unit of time or volume of receiving water.
