Understanding Dredging Permits

Most dredging projects are regulated by a government entity. Many, however, qualify for an exemption. In many states industrial tailings ponds are exempt if there is no discharge. For guidance in obtaining a permit, the first logical step is contacting the U.S. Army Corps of Engineers. They will direct you to the proper state authority that administers the Clean Water Act. The Corps only gets involved if your project involves wetlands or Section 10 navigable waters. This restricted Corps authority is the result of a recent court ruling.

Nailing Down Permit Details

Once you are directed to the proper state authority you will encounter various requirements for effluent, turbidity, and chemical analysis. Generally speaking, coastal states have more stringent standards than inland states. Each state has a different permit application process and some require professional engineering certification. There can be significant fines for proceeding with a dredging project without prior permit approval. Save yourself time, money, and a headache — make sure your permits are in order.

Using Geotubes

Geotubes are large, synthetic bladders used to dewater solids with the aid of polymer injection. Typically biosolid residue ponds are only 5%-10% solids by weight. Water treatment residue may measure slightly higher. The purpose of geotubes is to settle out residue particles and return the clarified water to its source. With time geotubes can dewater the material to be 30%-65% solids, depending upon the material. Haulage costs are significantly reduced by hauling 50% solids instead of 5%.

Geotube

An Expanding Market

We performed our first geotube project in 2008. This market is expanding and in the last two years geotube projects represented 75% of our work. Energy Resources, Inc. has the equipment and manpower to perform these specialized projects.
