WOCA 2017 Abstracts from SCS Engineers

A variety of CCB/CCP related topics guaranteed to enhance your knowledge. Click the title to read or share these papers.

Jeff Marshall – Mitigating Hydrogen Sulfide Issues at Coal Combustion Residuals and Municipal Solid Waste Co-disposal Sites – Learn about the biological, chemical and physical conditions necessary for FGD decomposition and hydrogen sulfide generation. Marshall will explore technologies that remove and treat hydrogen sulfide from landfill gas and present recommendations for reducing the potential for FGD decomposition at co-disposal facilities.

Eric-NelsonEric Nelson and Lindsay Motl – Working Through Location Restrictions to Expand the Ottumwa Midland Landfill – The final Coal Combustion Residual (CCR) rule introduces new challenges for companies developing new landfills or expanding existing sites. Join us to learn how Alliant Energy overcame these challenges and expanded the Ottumwa Midland Landfill (OML) to accommodate increased byproduct disposal rates from new emission control projects.

Steve Lamb and Floyd Cotter  – Selecting the Right Closure Cap Option for Your Surface Impoundment or CCR Landfill – Alternative capping options have recently emerged in the industry, such as exposed geomembrane liners or synthetic turf/geomembrane liner systems. Some of these alternative capping options have many advantages over their traditional counterparts. These experts describe the advantages and disadvantages of alternative capping options.

Get to Know the WDNR’s Waste and Materials Management Study Group

April 5, 2017

The Wisconsin Department of Natural Resources (WDNR) initiated a Waste and Materials Management (WMM) Study Group to provide constructive feedback on policy and technical issues. There are also five subgroups assigned to research selected topics and develop recommendations for presentation to the full group.

The study group and subgroups include a mix of regulators, industry representatives, environmental group representatives, researchers/professors, and consultants.

The WMM study group has five subgroups working on along with resources related to the area of study:

 

Get Involved

  • Visit the Waste and Materials Management Study Group website
  • Subscribe to the WMM email list
  • Attend a study group meeting – all meetings are open to the public

 

Feel free to contact Tom Karwoski or Betsy Powers for more information; active study group members ready to answer your questions and help you get engaged in the WMM.

February USWAG CCR Workshop – Alternative Capping Options and How Regulatory Agencies View Them

February 13, 2017

At the upcoming USWAG CCR Workshop Feb 22-23 in Arlington, VA, Steve Lamb and Floyd Cotter of SCS Engineers will present a session about the advantages and disadvantages of emerging alternative capping options, and how different regulatory agencies are viewing these options.

About this Session: Traditional final cover and capping design for coal combustion residual (CCR) surface impoundments and landfills have included compacted soil liner, geomembrane liner, drainage layer, and a vegetative soil cover. But coal-fired plants oftentimes don’t have the large volumes of soil that it takes to implement these options.

Alternative capping options have recently emerged in the industry such as exposed geomembrane liners or synthetic turf/geomembrane liner systems. Some of these alternative capping options have many advantages over their traditional counterparts. These advantages include faster installation times, minimal need for soil, improved storm water quality, and reduced maintenance and post-closure costs. For surface impoundments, alternative capping designs can also greatly reduce the amount of disturbance of the existing CCR material within the impoundment.

About Steve Lamb: Steve Lamb, PE provides SCS with over 27 years of experience in solid and hazardous waste management, environmental engineering, civil engineering, hydrology and hydraulics, landfill engineering, remedial design, and regulatory compliance. Mr. Lamb is a Vice President and director of SCS’s Charlotte, NC office.

About Floyd Cotter: Floyd Cotter specializes in solid waste management projects. His project work involves all areas of solid waste management including planning, permitting, transportation, landfill design, construction, and monitoring. Mr. Cotter is also experienced in general civil engineering, construction oversight, environmental site assessments, closure and post-closure plans, and permit and contract document preparation.

Take me to the conference details, please.
