Solid Waste Engineering Services - Key Personnel

ARLEN STRIEGL, PE VICE PRESIDENT, CIVIL ENGINEERING Arlen is a professional engineer with 13 years of professional experience, primarily in support of civil and geological engineering projects for the power, mining, and solid waste industries. He has been responsible for key technical and project management roles on numerous Class I injection well permitting, design, and construction projects including leading groundwater flow modeling, well design, and hydraulic systems design; permitting, design, construction, and test plot monitoring of solid waste cover systems; and design and construction of small- and large-capacity water pumping and pipeline systems. His experience includes deep wastewater injection well permitting, design, and construction observation; permitting, design, construction, and monitoring of long-term field-scale lysimetry projects; bid and construction package development; hydraulic analysis and design; large diameter pipeline inspection, design, and construction oversight; construction cost estimating and scheduling; surface water modeling and design; hydrologic data collection and analysis; and unsaturated and saturated flow modeling at local and regional scales. PROJECT EXPERIENCE Confidential Client, Class I Injection Wells, Michigan: Project manager supporting a technology screening and alternatives evaluation for management of an ash landfill leachate and other contact waters, including conducting a preliminary feasibility study for disposal of the wastewater via a Class I non-hazardous injection well. Arlen developed comparative capital and annual operations and maintenance costs to demonstrate that the Class I injection well was the most cost-effective over the life cycle. He prepared and submitted Class I non-hazardous injection well permit applications to Michigan EGLE and EPA Region 5. Arlen is beginning work on the design of the surface infrastructure upgrades. Select Water, Class I Injection Well, Dishon Disposal Facility, North Dakota: Technical lead for the design and permitting of a Class I non hazardous injection well for management of contact water from a special waste landfill in northwest North Dakota. Arlen performed analytical modeling of the formation response to injection and well design. The North Dakota Department of Environmental Quality has issued the Draft Permit (indicating their intent to issue a Permit to Inject) and Fact Sheet, and the public comment period has closed. Waste Rock Stockpile Cover System Design and Construction, Confidential Client, Minnesota: Project manager and design engineer for engineering, design, and bid package development associated with construction of a composite cover system (earthen materials combined with a geomembrane-supported geosynthetic clay liner) for closure of a waste rock stockpile. The waste rock stockpile was progressively covered over a period of two years, each of which required separate designs, bid packages, and construction mobilizations.
