- Adam Goodin is a senior civil engineering student at the University of Kentucky interning for his third rotation at Duke Energy's Gibson Station. - During this rotation, he is providing document control and engineering support for various projects including a unit refurbishment, mercury re-emission project, and the planning and design of a dry bottom ash conversion system. - One of his main responsibilities is supporting the engineering efforts for the dry bottom ash conversion project which is being undertaken to comply with new EPA regulations and will involve designing and installing a continuous dewatering and recirculation system over the next 3-4 years.

2. About Me
■ University of Kentucky
– Senior
– Civil Engineering
– Graduation: 8/16
■ 3rd Rotation with Duke
– Woodsdale (Spring 14)
– Plainfield (Fall 14)
– Gibson Station (Current)
■ Gibson Station, Capital Group
– Mentor: Mick Harpenau

3. My Safety Moment
■ Participated in Sitewide Safety Stand-down
– Walkdown with experienced Duke and Contractor
Management with the sole purpose of eliminating
hazards in the workplace
■ Looked for technical malfunctions
– Deteriorating grounding equipment
– Broken/corroded conduit
■ Housekeeping
– Ladders in isleway
– Stray pieces of wood and metal could become falling
object

4. Responsibilities this Rotation
■ Document Control on Unit 5 FGD Structural Refurbishment
– Maintained IFC Drawings and updated for revisions
– Provided Field Support
■ U5 Mercury Re-emission project
– Developed P&IDs
– Created Valve Lists and Valve Numbers
■ Involved in fall outage coordination meetings
– Logistics of large scale project
– Schedule formed, laydown areas designated, scope of work

5. Dry Bottom Ash Conversion
■ Support Engineering Efforts on the recently
initiated Dry Bottom Ash Conversion Project
– April 2015 EPA Ruling
– Gibson to adopt a Continuous Dewatering and
Recirculation (CDR) System
– Locate Existing Underground Drawings
– Obtain Existing Area General Arrangement (GA’s)
Drawings
– Layout Route for new Sanitation System piping

6. Dry Bottom Ash Conversion (Cont.)
– Locate Existing Sanitation System Drawings for
locating tie points
– Layout new Sanitation System GA’s,
■ Effluent Guidelines
– Review EPA’s proposed rules
– Gained Consensus on liner requirements as they
pertain to the DBA design
■ Researched and scoped out equipment for installation of a Water
Table Monitoring System

8. Water Table Testing
■ CCR Impoundments must be constructed with a
base/liner located 5 feet above the water table
■ Researched EPA regulations “uppermost aquifer”
■ Developed a Request for and obtained Proposal
for a groundwater measuring system (Solonist)
■ Project Manager currently working with Site
Environmental Representative to obtain approval
for installation.
■ Some of this slide will be moved to slide #

10. Bottom Ash WTD Conversion Alternatives
Continuous Dewatering & Recirculation System (CDR) with Remote SFC’s

11. Benefits
■ Allow Gibson Station To Stay in Operation
■ Learned basics about the business aspect of power generation
– How EPA rules impact Utilities and ultimately the Ratepayer
– Investing in Capital
■ Doubled the workforce on this project
■ Saved the team time

12. Conclusion/Summary
■ Going forward, the project team will continue juggling the outage
projects and work towards meeting the deadline on the WTD Ash
project
■ The drawings I have accumulated will be used along with the 3Ds
from UCC to place the high pressure pipes in the plant
■ We will hopefully begin the construction process on the
piezometer soon, then we will be able to determine if the base of
the Continuous Dewatering System will need to be built on
ground level or not

13. This Rotation
■ More opportunity to get involved
■ More responsibility
■ Transitioning from a corporate setting
■ Work alongside other engineering disciplines
■ The potential benefit of 2 consecutive terms

14. Looking Ahead
■ After graduation, I would like to build upon my knowledge in the
power industry
■ Potential project management/ structural focus
