Scott Energy's Jeff Tyson, P.E., will be presenting at the 25th International Petroleum Environmental Conference (IPEC) in Denver, CO. This year's conference will be held Oct. 30 to Nov. 1, 2018, at the Grand Hyatt Denver Hotel. Jeff will be presenting on two topics in the Waste Management and Pollution Prevention Session, including Concerns Over the Use of Geomembrane Liners for the Long Term Storage of Oil and Gas Wastes, and A Comparison of Drilling Wastes to Coal Ash: Potential Environmental Impact, Regulations, and Management Techniques.
"Geomembrane liners, sometimes referred to as poly-liners, are commonly used in the oil and gas industry as a barrier to protect soil and groundwater from contamination. There are several types of geomembrane liners, ranging from polyvinyl chloride, chlorinated polyethylene, ethylene propylene rubber, polypropylene, and high-density polyethylene, among others. The type of geomembrane selected is dependent upon the chemicals being contained. Geomembranes can be used for the short-term storage of certain chemicals and wastes and are often utilized as an engineering control for long-term storage of drilling wastes, such as with reserve pit closure, which is intended to last indefinitely; however, geomembrane liners, while persistent, do not last forever, even under controlled conditions. This presentation will discuss concerns over the degradation of geomembrane liners over time, leading to potential environmental concerns in the future." -Jeffrey Tyson, P.E.
"Over the last decade, wastes from the power generation industry (e.g. coal ash), have been under increased scrutiny from the public and regulators alike. Ultimately, new rules and policies were put in place to ensure protection to human health and the environment from coal ash, including the establishment of minimum national standards regulating the location, design, and operation of existing and new coal ash landfills and surface impoundments. From a chemical perspective, coal ash contains inorganic contaminants such as heavy metals; however, they do not contain organic contaminants such as TPH and BTEX, as do some drilling wastes, such as oil-based drilled cuttings. Drilling wastes often contain higher concentrations of the constituents found in coal ash, as well as constituents that are not found in coal ash. This presentation will compare the differences between coal ash and drilling wastes, such as the chemical and physical properties, the amounts generated, the regulatory requirements, and the management techniques." -Jeffrey Tyson, P.E.
Last year, Jeff presented at IPEC in San Antonio, TX, on Creating Value and Reducing Costs While Protecting the Environment, an overview of how to legitimately recycling drilling wastes and how to avoid sham recycling per the USEPA's definition. His presentation can be downloaded HERE. Scott Energy is also pleased to announce that Roy Thun with GHD will be presenting on ITRC's TPH Risk Evaluation Guidance. His presentation will provide an overview of ITRC's forthcoming guidance document on TPH Risk Evaluation at Petroleum Contaminated Sites. Scott Energy is a proud supporter of the Interstate Technology and Regulatory Council, and is assisting in the development of this guidance document.
