World of Coal Ash 2019

May 13, 2019

The World of Coal Ash (WOCA) conference is an international conference organized by the American Coal Ash Association (ACAA) and the University of Kentucky Center for Applied Energy Research (CAER). The 2019 conference will be held May 13-16, 2019, in St. Louis Missouri.  This 8th joint biennial meeting will focus on the science, applications and sustainability of worldwide coal combustion products (CCPs) as well as gasification products.

SCS Engineers is a Platinum sponsor of this year’s conference, and numerous SCS professionals plan to present or attend, including our Senior Vice President of Environmental Services, Mike McLaughlin.  Our presenters will be:

  • Monte Markley, PG – “Midwest CCR Leachate Disposal Options Evaluation and Disposal Case Study”
  • Eric Nelson – “Finding Balance: How Future Use Guides Ash Pond Closure Strategies”
  • Nicole Kron and Eric Nelson – “State vs Federal CCR Rule Regulations: Comparisons and Impacts”
  • Phil Gearing (with Lindsay Motl of Alliant Energy) – “How to Minimize CCR Landfill Leachate and Contact Water Management”

Check back for more details, which will be posted as the agenda is finalized.

CCR Leachate Disposal Options Evaluation and Disposal – WOCA 2019

April 11, 2019

World of Coal Ash in St. Louis, May –13-16, 2019 event details.

A Midwest power plant that was constructed as a zero discharge facility in 2012 was experiencing water management issues due to excessive absorber recycle water with concentrated chlorides and leachate generation from the CCR landfill at the facility. The facility started exploring wastewater management options in 2013 that consisted of evaluating the feasibility of a deep injection well as a fluid disposal option and the results indicated that this option was a technically feasible alternative.

From 2014-2015 the plant continued to experience water balance and chlorides management challenges and conducted a plant review and water balance study to see if the chloride concentration and leachate generation issue could be resolved through process changes within the plant. The resulting water balance study concluded that while minor changes and optimizations could occur, it would not resolve the underlying water quality or water balance challenges at the facility. Other water disposal and management options were also explored by the plant in that included RO, evaporators and the deep well as retained alternatives.

In 2016, the deep injection well was selected as the preferred water management alternative and permitting was initiated. The goal was to get the deep well permitting started while the plant refined plant process modifications and additional water quality data on the feed water(s) is collected.

Water quality data from the site has indicated that iron, carbonate and sulfate are the dominant water quality parameters that drive scaling within the current system and will need to be addressed prior to injection so the well does no scale and clog.

The deep well was completed in 2018 and the final surface treatment system is currently under design. The facility anticipates full-scale operation of the system in early 2020.

State vs Federal CCR Rule Regulations: Comparisons and Impacts

March 28, 2019

World of Coal Ash in St. Louis, May –13-16, 2019 event details.

When the Federal CCR rule went into effect in 2015, it was a new regulatory layer on top of a widely varying landscape of state regulations affecting CCR management in impoundments and landfills. Some states already had significant regulations on the books for CCR impoundments and/or landfills, while others did not. Where state regulations existed, they varied widely from state to state. While a few states have moved toward closing the gap between state and federal CCR requirements, many utilities continue to face confusing and conflicting requirements coming from different regulatory programs as they move ahead with managing their CCR facilities.

Through case studies, SCS Engineers will share state-versus-federal regulatory challenges utilities have encountered in different regions of the country during landfill design and management, impoundment closure, and groundwater monitoring and reporting since the implementation of the Federal CCR Rule. For example, some sites have completely distinct groundwater monitoring programs under state versus federal rules, with different well locations, well depths, and monitoring parameters for the same facility. We will highlight unique approaches to bridging regulatory gaps and resolving regulatory conflicts between state and Federal CCR requirements.

SCS will also share insights gained on the long-term potential for regulatory resolution of these issues based on discussions with state regulators in multiple states.

Minimize CCR Landfill Leachate and Contact Water Management

March 21, 2019

World of Coal Ash in St. Louis, May –13-16, 2019 event details.

Learn how to minimize leachate and contact water management at coal combustion residual (CCR) landfills using good design, physical controls, and operational practices. Through our presentation of case studies, you will learn how to assess leachate and contact water management issues and implement techniques to minimize leachate and contact water management at your landfill.

Leachate management and contact water management at CCR landfills can be expensive, cause operational headaches, and divert valuable resources from other critical plant needs. Our presentation will provide you with useful tools to ensure your landfill is designed and operated to effectively reduce leachate and contact water and alleviate operator stress. We will present case studies that highlight how design features, physical controls, and operational practices have effectively decreased leachate and contact water management at CCR landfills.
