April 12, 2016 - At the recent 2016 Energy, Utility & Environment Conference (EUEC) in San Diego, Sargent & Lundy staff presented a wide range of papers. From presentations regarding the challenges of plant retrofitting to the impacts on the long-eared bat, Sargent & Lundy presenters covered the gamut of current energy and environmental topics, including:
Structural Design Challenges of the Conemaugh SCR Project, presented by Krunal Patel and co-authored by Charles Nelson and Michelle M. Atto, all of Sargent & Lundy, and Scott Matheson of NRG Energy. The presentation reviewed the challenges for developing cost-effective, reliable, and sustainable systems while locating large support columns and duct sections within the confines of the existing plant, which had to remain in service throughout most of the construction phase.
Northern Long-Eared Bat and the Interim 4(D) Rule: Considerations for Transmission Line & Siting Permitting, presented by Russell Light and co-authored by Daniel Laubenthal, both of Sargent & Lundy. The presentation provided a summary of topics, including: Northern Long-eared Bat Listing and the association with white-nose syndrome; the interim 4(d) rule; experience on transmission line siting and permitting projects.
U.S. EPA’s Final CCR Rule . . . Existing Ash Ponds: Close in Place or Clean Closure—How to Decide Which Option Is Right for Your Site, presented by Douglas Dahlberg and co-authored by James Perry, both of Sargent & Lundy. The presentation summarized 16 critical compliance deadlines for required document preparation, analysis, reporting, and actions that need to be taken, itemized factors that affect the decision between selecting closure in place versus clean closure alternatives, provided estimated costs for both alternatives, and presented two case studies that incorporate both options.
An Overview of Impingement Technology Selection Procedure, presented by Mehrdad Salehi and co-authored by Ken Snell and Joy Rooney, all of Sargent & Lundy. The presentation offered an overview of the available impingement control technologies, their recent improvements, examples of technology selection procedures, and their unique aspects/limitations.
316(b)—An Overview of Entrainment Technical Feasibility and A Cost Evaluation Study, presented by Sargent & Lundy’s Joy Rooney. The presentation identified and described the critical design parameters of entrainment technologies and the level of engineering needed to effectively evaluate the technical feasibility and to establish costs. The presentation also described an approach for developing control technology costs and discussed the concept both of facility-level costs and social costs.
Approaches to ELG Compliance for FGD Waste Waters, presented by Kristen Bell, Sargent & Lundy. The presentation identified unique ways that utilities can treat or eliminate FGD waste water to comply with the ELG rule.
