40 CFR §230.73

1. (a)Where environmentally desirable, distributing the dredged material widely in a thin layer at the disposal site to maintain natural substrate contours and elevation;
2. (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;
3. (c)Using silt screens or other appropriate methods to confine suspended particulate/turbidity to a small area where settling or removal can occur;
4. (d)Making use of currents and circulation patterns to mix, disperse and dilute the discharge;
5. (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;
6. (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;
7. (g)Setting limitations on the amount of material to be discharged per unit of time or volume of receiving water.
