area can be built?
c) List the area of the potential spoil area.
7) The maximum distance that the material must be
8) The minimum distance that the material must be
9) The elevation above sea level of the site.
10) The static head. This is the elevation
difference, in feet, between the water surface where dredging will take
place and the elevation where the material will be discharged.
11) Is the material all in one location, or will
the dredge need to be moved from one location to another? If the dredge
must be moved:

length and width.
b) List the cubic yards in each location.
c) The distance between locations.
d) Can the dredge float between locations or must
it be transported over land?

a) List size.
13) Is there an area available, to set up a large

15) Are there any limitations on the flow rate from
a) If yes, what are they?
16) What is the time period to complete the work?
This should be the time from a notice to proceed until the project must

percent of each type. Suggested terms are, boulders, cobbles, gravel,
course sand, medium sand, fine sand, stiff clay, medium clay, soft clay,
dense mud and soft mud. Other descriptive terms can be: window putty,
peanut butter, catsup.

pond, list the type of material, lime sludge, sewerage sludge, ferric
chloride, paper sludge etc.
Is the sludge primary sludge or secondary

19) Has a grain size analysis been made?
a) If yes, provide the grain size log sheets.
20) Is the material hazardous?
a) If yes, describe.
21) Will dewatering be required?
a) What type of de-watering will be used?
22) Will personal protective gear be required?
a) If yes, at what level?
23) Will OSHA training be required?
a) If yes, at what level?
24) Provide a phone number where you can be
25) So the site can be viewed with satellite
imagery, provide the following:
