Design Criteria - §257.72 Liner Design Criteria PacifiCorp – Naughton Power Plant FGD Pond 5
October 30, 2017
1.0 INTRODUCTION The PacifiCorp Naughton Power Plant is located approximately three miles southwest of Kemmerer, Wyoming.
This report addresses the requirements of §257.72 – Liner Design Criteria, as it pertains to FGD Pond 5 at the
Plant. FGD Pond 5 was constructed in 2017. This report presents the initial evaluation immediately following
completion of construction and prior to the pond being placed into service.
Specifically, §257.72 indicates the pond must be constructed with a composite liner system or an approved
alternative liner system. A composite liner system must consist of an upper component and a lower component
where: a) the upper component consists of a geomembrane liner (minimum 60-mil thick for HDPE) and b) the lower
component consists of at least a two-foot layer of compacted soil with a hydraulic conductivity of no more than 1x10-
7 centimeters per second (cm/sec). The upper component must be installed in direct and uniform contact with the
lower component.
2.0 EXISTING CONDITIONS
The Naughton Power Plant is located approximately 3 miles southwest of Kemmerer, Wyoming. The Plant consists
of three coal-fueled units, rated with a net dependable capacity of 156 MW, 201 MW, and 330 MW, respectively.
Coal combustion by-products at the Plant include several types of materials including bottom ash, fly ash, and FGD
materials. FGD Pond 5 was constructed in 2017 at the location shown on Figure 1. The pond has a permitted
capacity of 1,467 acre-ft which is expected to provide approximately 10 years of disposal capacity. The pond may remain operational when full to allow additional evaporation of water. As water evaporates, additional effluent may be added eventually filling the pond with solids. When filled with solids or when continued operation is no longer feasible, a cover will be constructed and the pond will be permanently closed.
The pond has a surface area of 49 acres at the crest with a maximum interior depth of 46 ft. The pond is located on a topographically high area with surface water drainage away from the pond in all directions. The only source of water or waste entering the pond is through two effluent delivery pipelines as well as any precipitation falling within the pond area. No surface water run-on is allowed to enter the pond. The pond has no discharge outlets or spillways (all water entering the pond will be evaporated). The pond embankments have 3 horizontal to 1 vertical slopes and was constructed using soil excavated from within the pond limits and an adjacent borrow area. The pond foundation materials consist of stiff clay and claystone bedrock. Permanent ballast consisting of grout filled tubes was placed over the geomembrane to prevent wind damage. A chain link security fence was installed around the pond to prevent larger wildlife from entering the area. A bird hazing system was installed to reduce impacts to migratory water fowl.
The pond was constructed with a composite liner system consisting of a 60-mil HDPE geomembrane (upper component) in direct contact with a two-foot layer of compacted soil with a hydraulic conductivity of no more than 1 x 10-7 cm/sec (lower component) (Clay liner material obtained from claystone bedrock borrow indicated in Appendix B).
3.0 CONCLUSION
As indicated above, FGD Pond 5 was constructed with a composite liner system in accordance with the
requirements of §257.74 – Liner Design Criteria.
