Overview

Power generators have developed and revised their ash management, ash storage procedures, and groundwater monitoring plans to keep their facilities in regulation. With the approach taken by the Trump administration’s EPA, District Court rulings, and the impact of citizen lawsuits, there are future changes yet to come with the industry adapting the best they can.

This coal ash focused conference will continue the discussion on how any changes may affect the industry with discussion on generators’ ash closure plans, the CCR rule’s regulations and changes, impacts of groundwater monitoring and remediation, safety, and how utilities are accomplishing closures, and more.  In addition to closure and remediation work, there will also be discussion on the beneficial reuse of ash taken from impoundments.

Learning Outcomes

  • Review an update on the state of CCR regulations at the state and federal levels
  • Discuss the details and challenges with CCR groundwater liability and litigation
  • Describe some aspects of CCR dewatering and its impacts on the receiving waters
  • List the met objectives and steps of a successful closure and removal/reuse of ash from a site
  • Review an alternative use for closed sites as a site for solar placement and the progress made since first introduced
  • Engage in a question and answer panel on the challenges and opportunities involved with ash management and removal
  • Discuss some lessons learned in the harvesting of ash from impoundment closures
  • Review the options, steps and practices to enhance the overall safety of a pond closure
  • List the methods and options available for beneficial use of ash products

Agenda

Tuesday, April 21, 2020

8:00 – 8:30 a.m. :: Registration and Continental Breakfast

8:30 – 8:40 a.m. :: Introductions


8:40 – 9:40 a.m. :: CCR Rule Update

This presentation will provide an update on key developments of the CCR Rule, including potential and proposed amendments to the rule as well as pressing compliance deadlines.  An update will also be provided on state initiatives to obtain program approval from EPA.

Ali Abazari, Partner, Jackson Walker, L.L.P. and Counsel for the Texas CCP Coalition


9:40 – 10:30 a.m. :: Liability and Litigation Related to CCR Groundwater Quality Impacts

This presentation will discuss the details and challenges with CCR groundwater impacts, applicable regulations, and related case studies and case law.

Douglas Henderson, Attorney, Partner, Troutman Sanders (Invited)

10:30 – 11:00 a.m. :: Networking Break


11:00 a.m. – 12:00 p.m. :: CCR Impacts to Receiving Waters

This Duke Energy presentation will cover the observed and documented impacts and real-world results of dewatering and its impacts on the receiving waters.

Maverick Raber, Manager, Environmental Sciences, Duke Energy

12:00 – 1:00 p.m. :: Group Luncheon


1:00 – 1:50 p.m. :: Successful Closure and Beneficial Reuse

On May 6, 2019, Santee Cooper hauled out the last truckload of pond ash that was stored at the former Grainger Generating Station near Conway. In total, the project hauled over 1.7 million tons of ash out of the two ponds at Grainger alone, with 1.1 million tons of this ash going to the cement industry for beneficial use. This presentation will review what was accomplished at Grainger but also cover Santee Cooper’s beneficial reuse practices.

Todd Crawford, PE MBA, Senior Engineer – Generation Construction Management, Santee Cooper


1:50 – 2:45 p.m. :: Alliant Energy’s Solar Ready Closed Sites Progress

Alliant Energy completed closure of coal combustion residual (CCR) surface impoundments at two facilities and is utilizing these closed ponds to adapt to transformations within the utility industry and create “solar-ready” sites.  This case-study presentation will discuss the opportunities for solar generation at closed CCR ponds, the civil and geotechnical requirements for their installation and provide an overview of two closure designs that facilitate solar installation and what progress has been made with solar since closure.

Jeff Maxted, Lead Environmental Specialist, Alliant Energy

2:45 – 3:15 p.m. :: Networking Break


3:15 – 4:45 p.m. :: Panel Discussion: Challenges Facing CCR Management

Engage in a discussion with panelists on the challenges and opportunities involved with the continued management of ash, impoundment closures and related groundwater. Additional topics will consist of project safety since with so much new pond and landfill activity being generated.

8:00 – 8:30 a.m. :: Continental Breakfast


8:30 – 9:20 a.m. :: Ash Harvesting for Beneficial Reuse

Lakeland Electric, like many other generation owners, have been removing ash from ponds in the closure process and not only storing the ash in a landfill but seeking opportunities for its reuse as much as possible. The presentation will review what has been done and what is being planned and lessons learned from this harvesting of ash.

Ken Riddle, Supervisor of Chemical Process – Energy Production, Lakeland Electric


9:20 – 10:10 a.m. :: Dewatering to Enhance Safety During Pond Closure

We will review and discuss the options, steps and practices that should be taken to safely and successfully dewater a project so as to enhance the overall safety of a pond closure.
