With 30 years of environmental engineering experience, Dean has developed an extensive array of skills and experiences ranging from leading hazardous waste incinerator trial burns at refineries to teaching Naval Architects about sustainable ship design to preparing integrated water/wastewater strategies for refineries, power plants, pharmaceutical plants and yogurt manufacturers.
Dean has a demonstrated track record of building and maintaining high value relationships by providing creative solutions to difficult business and environmental sustainability and regulatory compliance problems. He has a broad span of expertise and experience across air quality, risk management, regulatory compliance, wastewater, pollution prevention, sustainability, and hazardous waste. This experience has included developing and managing project teams to manage clients’ EHS-S needs, including developing environmental monitoring programs, emergency response programs, waste management programs, and sustainability programs. Much of his work in sustainability programs has been focused on wastewater/water re-use and recycling in many industries, supporting pharmaceutical, food & beverage, O&G, and power generation.
Recently on a project for the Orlando Utility Commission (OUC) his task was to bring the Stanton Power Plant to its goal of zero liquid discharge. Beginning with client workshops and on-site evaluations, he developed a sustainable engineering program and led the facility through a series of engineering, operational, and process changes to improve the water use and re-use. The program is being implemented with expected savings of 450,000 gallons of water per day, 1MW of energy per day, and $5M in annual costs. Along with the Senior OUC Plant Engineer he has co-presented as an invited speaker the details of this project as a case study at two Pollution Control Users Group conferences for power plant operators. The listing below captures some key aspects of those showcase projects where the results of Dean’s work were the most valuable.

Technical Director for Municipal Wastewater re-use project for Valero Refinery – Project involved developing and overseeing the process engineering and distribution system design to utilize tertiary treated wastewater provided by LADWP in the cooling towers operated by the Valero Refinery located at the LA Harbor.
Orlando Utilities Commission – Zero Liquid Discharge System Improvement Alternatives Study Technical Director and Lead engineer – Developed a comprehensive alternative evaluation study to identify recycling and re-use options for process wastewater streams, FGD scrubber blowdowns, stormwater, and coal pile run-off and other flows. Process changes at the Power Plant have led to conditions that threaten the Power Plant’s zero discharge certification and their compliance with SEEGs. Alternative evaluation workshops with the client led to a number of solutions that the client chose to implement to increase recycling of process waters and to reduce flows discharging to on-site surface impoundments. Tools developed include an equilibrium water chemistry dynamic power plant model, power plant water balance model, and a power plant hydrology model to assess the impact of solutions and storm events on success of maintaining a zero discharge certification.
AEP Turk Wastewater Treatment System Evaluation and Upgrade Recommendations – Lead Project Engineer for evaluation project to identify solutions to manage coal pile runoff pond water that was over flowing and into facility make-up water pond. This impaired plant ZLD system.
