" We had the quarry and it made sense to go through the permitting process," Woodbridge says. " We'll have the pro - cessing and drying equipment to pro - cess wet materials and we'll be able to do it for our own waste, as well as our competitors. We are also in talks with some companies to set up mobile pro - cessing plants for working in the core of the GTA where we can setup at a centralized site to accept the slurry." The potential for its own quarry notwithstanding , in the last 10 years, Earth Boring has moved away from in- cluding a small lump sum for disposal in bid packages to making it an actual line item. To come up with that line item number they estimate disposal volumes, frequency, fees and other as- sociated expenses. Investing and Education In the Northeast and Midwest of the United States Ellingson Trenchless faces many of these same problems on its projects. Much like Earth Boring Co., Ellingson has made a huge invest- ment in mud recycling systems in the last decade. According to Rob Tumble- son, director of business development at Ellingson Trenchless, they also look at the specifications of the project before bidding to determine the best disposal solution. " If we are working in the southern states or the Dakotas there are a lot of opportunities for spoils disposal ," Tumbleson says. " If we are working Pennsylvania, New Jersey or New York, transportation and disposal is more of a concern. In many cases, owners will generally find places for disposal and include in the specifica- tions for us to choose from and then we include where we will dispose of it in our bids." And though some may look at this issue as being one of regulators and legislators vs. the industry, these in- dustry insiders say that is not often the case. During a recent fly-in to Washing- ton, D.C . with the Distribution Con- tractors Association Tumbelson dis- covered that most of the problems as it pertains to drilling fluid is at the state and local level . The federal EPA sets a minimum standard, he says, and many states then go above and beyond that . " Most of the drama for mud dispos- al seems to be on the pipeline proj- ects. Most of the big HDD work is for gas and oil pipelines and there seems to be more scrutiny on those projects," he says. " The municipal projects we work on don't seem to come under as much scrutiny as [like- sized] oil and gas pipelines projects." Bates agrees, noting that much of the pressure is due to HDD 's link to the non-conventional oil and gas boom in North America and a lack of awareness on the part of many people as to the differences between the drill - ing fluid solutions used in downhole drilling and fracking vs. HDD and mi- crotunneling . Levings notes that the fluids are completely unrelated. The fluids de- veloped to use with utility boring sys- tems were developed to have a mini- mal impact . The industry has never needed the more complex oil and gas The Vermeer Mud Hub is a slurry solidification system and is a stationary plant where contractors can unload their wet slurry from vacuum excavation equipment. The unit then solidifies the slurry for easier disposal.
