Section 230.73 - Actions affecting the method of dispersionThe 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;(d) Making use of currents and circulation patterns to mix, disperse and dilute the discharge;(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.
