About this file
This is an addendum to an Invitation to Bid (RFB-283-23) issued by the Commonwealth of Kentucky Department for Facilities and Support Services, Division of Engineering and Contract Administration for the Sequoia Energy AML Project in Leslie County, Kentucky. Addendum Three, dated July 10, 2023, addresses technical specifications and project scheduling for bidders. The document clarifies that existing principal spillway piping consists of 36" HDPE SDR17 pipe, that no lining is currently proposed for the new spillway channel, and that pipe headwall details are available in drawings AML 23-10-7 and AML 23-10-8. Additionally, the addendum directs bidders to refer to a separate Lynn Imaging addendum for all specification and drawing changes. The official bid opening date has been moved to September 14, 2023 at 10:30 A.M. Eastern Time due to technical reasons, representing a postponement from the original letting date.
The addendum addresses several bidder inquiries regarding geotechnical information, geogrid specifications, and spillway design details. Bidders are directed to the Kentucky Division of Abandoned Mine Lands website for Technical Specifications and Standard Details regarding geogrid installation requirements, which must meet the updated June 2021 Technical Specification standards. The document indicates that geotechnical reports and borings may be available through the permit package, though specific information about excavation on the east side of the spillway in existing ground is not explicitly provided in this addendum. No pricing terms, funding sources, or contract award information is included in this addendum.

1. What size and type of pipe is the existing piped principle spillway that is crushed?
The existing pipe is shown as 36” HDPE SDR17
2. Is there a Geotechnical Report and borings for the project? Asking because it looks like we will be excavating the east side of the spillway in existing ground.
As this is an existing slurry impoundment there may be geotechnical info available in the permit package. Existing highwall further around the contour also shows the material that may be encountered.
3. Will there be any type of lining required in the new spillway channel, such as riprap or matting?
At this time it is not proposed to line the spillway channel
4. Can you give us a detail for the pipe headwall?
The detail for the pipe headwall is included as AML 23-10-7 and AML 23-10-8
5. Can you provide a geogrid installation detail, that shows how it is to be installed, and what type of geogrid it needs to be?
Geo-grid shall meet the Technical Specification of Geo-Grid of updated June
2021. The Technical Specifications and the Standard Details are available on the website at the link provided below.
