Since there are many different scenarios pertaining to dredging projects, we have various options to choose from that will fit most situations appropriately. The sediment wm be removed using one of our different types of dredging equipment mcm.tioned below. There are also different types ofsedimsrt disposal methods mentioned below.

Harbor workers coverage's and others that allow us to work within, potable water facilities, contaminated facilities, offshore, navigable waterWays, lakes, rivers and streams. We have a current safe practices manual that is used lIS needed as well as a (JHA) Job Hazard Analysis work sheet. ,07/05/2008 17:07 8173575383 AUS_ACES PAGE 03/05 Commercial Divers andlQr our DredKe ooeratoJ:l Jfthe project has diving involved it wiJl be perfonncd usiag our conunercially oertified divers that llrc licensed through accredited commercial diving schools and arc experienced in o:ffsl1ore and inland diving operations. The $hallow air package that supports the diving operations will include at minimum; I ~Air compressor (2Scfln), Volume tank, 2-Dive hoses with communications, 2-Dive hats, dive manifold with a Pneumofathometer "depth gauge", 2-Communications Radios, Air filter, Secondary air supply, and Safety manual, OSHA first aid kit and Dive Flag. A.U.S. complies with OSHA-29 CFR part 1911 cooceming commercial diving operations. Our dredge operators are OUf fonner commercial divers that wanted a change of pace. DieMI Driven DredEiD2 E~..jDment A. Dredn Machine This is a portable dredge barge that is approximately 8 feot wide x 35 feet long and weighs 25,000 LBS This machine is for dredging projects that are etheT large in size or the sediment is compacted. This machine has an anger cutter head that is capable of a 15' digging depth. The suction is variable from 1000' GPM to 2,500 GPM tllrough a 6" hose. This machine is capable of dredging around 350 cubic yalds of sediment per 8-hr day. And erane will be needed to lower it into the water, so pll11'i for an entry point and exit point. The dredge is capable of pumping 2,500 feet away. (Note: Further distances can be achieved if needed for an additional cost.) B. FJo.atinl!-Hand-Dred2e-Jal1e This is a portable barge that is approxim.ately 8 feet wide x 25 feet long and weighs 3,500 LBS. We created this machine for dredging projects that are ham to get to with the large dredge machine or with conventional heavy equipment i.e., Excavators, Loaders etc. There is a 6" suction pipe underneath the barge that is coming from th0 large pump that a diver attaches a 6" suction bose to. Once the suction hose is attached, the diver starts vacuuming up the sediment and debris as needed. This machine works...Dattieularly great for DO.nds and/or lakes tls8$ have c!.!.v or a PVC lioer inttalled. This small barge will need a small crane OT a ski-trac forldift to loweT it into the water. The suction is variable from 100' GPM to 2,500 GPM through a 6" hose. This barge is capable of pmnping up to 1000 feet away (Note: Further distances can be achieved if needed for an additional cost.) The divers and machine dredge between 70 to 125 cubic yards a day all depending on the weight and compaction ofthe material. The barge contains a shallow air-breathing package for the divers for life support. C. Submersible Hvdraulic Materials PumD This pmnp package comes on a 25' Gooseneck trailer and has the shallow air~breatbing package loaded onto it. This pump package bas the 5tItI1e pumping and production characteristics as the floating hand--dredge barge mentioned above. This pump package is usually used on :smaller hand dredging projects like cleaning wet-wells, lift-stations, cleaning out crossover pipes and dredging small mounds of unsightly deposited sediment. This unit is mobilized near the shores edge; it has 100' hydraulic hoses with the package. Jf more hydraulic hoses are needed, they will be charged as an additional fee. Note all the equipment mentioned obove uses 6" hoses Add or 6" HDPE plastic discharge pipe. ~7/06/2008 17:07 8173676383 AUS_ACES PAGE 04/06 Disooul Methods A: J'ield/Puturel Tbe field method would have to have a large enough area to support the total cubic yards of sediment plus some extra room for water. The effluent discharge coming from the dredge pipe will be sprayed out over the property and left to dry. If the field is too small for the project, the muddy water will run back down the hill back into the body of water we arc worki1lg in. This method is not very commolt because of the large space that is usually needed. B. sediment pitlhoklift2 DOnd: A sediment pit is the most economical way ofhandJing dredged material. The pit would have to have a large enough area to support the total cubic yards of sediment plus some extra room for wateT. otl:entimes there is enough dirt leftover from digging the pit that can be used to create an earthen benn around the pit whieh will give the project more holding capacity. (fthere is not enough dirt on-site, extra dirt will have to be trucked in to help create the benn. c: G!Il1.ltextile SedimcntJlan:. A sediment bag is usually used if there is a flat area that a baglbags can me laid on. The most common size bag is 25' wide x 200' long and can contain 800 cubic yards of sediment. Basically one liner foot of bag can contain 4 cubic yards of sediment and the bags can be made in sizes ranging from 75' to 200' long. Th~e geou:xtilc eontainers are made out of high strength penneable fabric, which is capable of containing organics, plants, fine grain sludge. rocks, sand and other materials. The excess water drains filtered from the geocontaine:r through small pores in the fabric resulting in effective dewatering and efficient volume reduction of the contained material. Once a bag is full, It will take about one to two months for the material inside the bag to dry-out enough where it can be hauled off and properly disposed of. The Mississippi office of the U.S. Anny Corps of Engineers did a study on these sediment bags around 10 years ago and gave thel\1 a "robber stamp O.K. to use" pass for their dredging projects. D:->>e-~teriAI! roO off boxes: A.U.S. had SOTTle special dc-watering roll off boxes made for projects that are fully developed to the point where there are not any fields or open spaces for sediment bags. These boxes are parked on the side of the streets, parking lots, driveways etc and don't look very different from fCgular roll-off type boxes used in other industries. The muddy water coming from the dredge pump is discharged into the top of a roll-off dl:l-watering box through a manifold system. Once the muddy water enters the box the sediment is separated from the by a &pecialliner that is on the walls and floor of the box. The water runs through the filter fabric down the inner waUs of the box to the bottom of the box exiting out of several 6" ball valves. Hoses attach to the ball valves, which transfer the filtered water back into the body of water. Our dc-watering boxes are capable of containing between 1 S-to-2S cubic yards of$~diment. The weight of the sediment determines how many cubic yards of material can be disoharged into a box; the tnIcking company will determine that. gftentimes the WI:li2ht of the material is very heavy due to the water content and the box can only b.e fiUe.d uti %. which is around 15 cubic vard ofscdlment. Once a box is filled, It will need to be picked up by a roll-off service tnIck to be properly dispOsed of. ,07/06/2008 17:07 8173676383 AUS_ACES PAGE 05/06 Terms and Conditions .
