PART 1 – GENERAL REQUIREMENTS
1.1 Purpose
The purpose of this plan is to describe the quality assurance procedures to be uAlized during the
construcAon of the final soil cover at the north area of the North Pointe Solid Waste ConstrucAon
and DemoliAon Landfill (Landfill). The Landfill will be closed in a series of Stages with the first
Stage being complete in the fall of 2024. The primary goals of the quality assurance program are
to:

• Determine if proper construcAon techniques, materials, and procedures are used.
• Determine if the intent of the construcAon documents is met.
• IdenAfy construcAon problems and provide a method for resoluAon of any problem.
• Document the construcAon acAviAes.
Upon the compleAon of each final cover Stage construcAon; a final construcAon documentaAon
package will be prepared and submi`ed to the State of Utah Division of Waste Management and
RadiaAon Control (UDWMRC) for approval.

1.2 Document Format
The Quality Assurance Plan is divided into three secAons to idenAfy; 1) the general informaAon
and personnel associated with the project; 2) the detailed requirements of the quality assurance
program; and 3) the documentaAon and record keeping associated with the construcAon.

1.6 Construc6on Documents
A. ConstrucAon Drawings – Appendix A contains the plans for the final cover construcAon at
the north area of the Landfill. A preconstrucAon survey of the exisAng landfill cover (in the area
to be closed) may be uAlized to document the preconstrucAon grade and serve as a basis for a
post construcAon survey uAlized to demonstrate cover thickness. AlternaAvely, Landfill personnel
may elect to install grading stakes to indicate required cover thickness, or to dig test holes in the
final cover once soil grading is complete.

B. SpecificaAons – The only project specificaAons for the cover construcAon is presented in
Part 2.

C. Forms – The forms required to document the final cover construcAon are include in
Appendix B.

PART 2 – CONSTRUCTION QUALITY ASSURANCE

2.1 Introduc6on
This secAon describes the monitoring and tesAng that will be performed to assure that the final
cover construcAon meets the specified requirements.

2.2 Material Evalua6on
A. Site soils are fine grained in nature and are approved for final cover use. A copy of the
geotechnical test results for the site soils are included in Appendix C.

Import soil may be used for final cover construcAon with appropriate tesAng and approval prior
to use. GradaAon tesAng for the potenAal import cover soil will be performed at one gradaAon
test per 10,000 cubic yards of final cover soil. No addiAonal tesAng of the soils to be uAlized in
the construcAon will be required other than to document that a minimum of 24 inches of soil has
been placed.

B. Test Fill – No test fill will be required for this project.

2.3 Construc6on Tes6ng
A. Test Procedures – Final Cover soil will be tested according to the tests idenAfied in Table
1.

6 | Page

B. Test Frequencies – Soil will be tested according to the minimum frequency idenAfied in
Table 1.

2.4 Monitoring Requirements
The monitoring requirements will include verificaAon of final cover thickness.

2.5 Documenta6on and Control of Nonconformance
2.5.1 ObservaAon of Nonconformance

Whenever a nonconformance (cover thickness less than 24”) is discovered the Landfill Manager
will either document the locaAon of the nonconformance (to be corrected at a future date) or
have the ConstrucAon Team correct the cover thickness nonconformance as they are discovered.

2.5.2 Determining Extent of Nonconformance

Whenever a nonconformance is discovered or observed in the construcAon process, product,
documentaAon, or elsewhere, the Landfill Manager will determine the extent of the
nonconformance. The extent of the deficiency may be determined by addiAonal sampling,
tesAng, observaAons, review of records, or any other means deemed appropriate.

2.5.3 DocumenAng Nonconformance

All nonconformances (observed but not corrected) will be documented in wriAng on a Problem
IdenAficaAon / CorrecAve AcAon form. The documentaAon will occur immediately upon
determining the extent of the nonconformance.

2.5.4 CorrecAve AcAon

Since the only criterial item required for final cover construcAon documentaAon is cover soil
gradaAon and final cover thickness; the prescribed correcAve acAon is to add addiAonal soil unAl
a minimum of 24 inches of soil cover is documented.

2.5.5 VerificaAon of CorrecAve AcAons

The Engineer and DWMRC personnel will verify all correcAve acAons. The verificaAon will be
accomplished by site observaAons, depth tesAng (test pits), and photographs. VerificaAon of
correcAve acAons will be made during the postconstrucAon meeAng. Wri`en documentaAon of

7 | Page

the correcAve measures will be made by the Engineer on the second page of the Problem
IdenAficaAon / CorrecAve AcAon form.

2.6 Construc6on Surveys
A pre and post-construcAon survey may be performed by the Owner to document final cover
geometry and thickness. Test pits will be excavated to confirm survey data.

2.7 Revegeta6on
During the regrading of the landfill slopes, the orientaYon of the dozer resulted in grouser marks that are
perpendicular to the slope. Those ridges le[ on the slope by the equipment tracks will also minimize slope
erosion by providing interrupYon to the surface water flow.

Perimeter roads will be established at the top of all slopes once the final cover soil thickness is
documented, and no new soil is required to be placed on the side slope. The perimeter road will prohibit
water from flowing from the top of the landfill down the side slopes by direcYng the water laterally away
from the final cover.

The revegetaAon seed mix for the north area of the Landfill is presented below.

ReclamaYon Seed Mix (Per Acre)

Pounds PLS
Fourwing saltbush 10
Wyoming big sagebrush 0.75
Alksli sacabon 1
Blue grama 2.5
Bluebunch wheatgrass 14.25
Streambank wheatgrass 13
Smooth brome 15.5
Intermediate wheatgrass 10
Sandberg blusgrass 2
Sheep fescue 3
Slender wheatgrass 11
Western wheatgrass 17

The Owner may elect to coordinate revegetaAon efforts with local agricultural personnel or Utah
State University Extension office personnel to select a different seed mix or revegetaAon efforts
if iniAal revegetaAon is not adequately robust.

PART 3 – DOCUMENTATION

3.1 Recordkeeping

The quality assurance plan relies on the observaAons, tesAng, and associated documentaAon of
all construcAon acAviAes. The documentaAon acAviAes will be performed by the Landfill
Manager.

A. Daily/Weekly Record of ConstrucAon Progress – Due to the anAcipated method and rate
of construcAon; daily/weekly construcAon reports will not be uAlized. Soil will be moved by the
ConstrucAon Team and potenAally stockpiled on the exisAng landfill for several weeks/months
before being graded down the landfill slopes. Once enough material has been stockpiled; the
landfill operators will grade the stockpiled material out to form the minimum 24-inch-thick final
cover.

B. Monthly Record of ConstrucAon Progress – Since the final cover construcAon will be done
at a relaAvely slow pace; the Landfill Manager will fill out monthly construcAon record (during
the months that the final soil cover materials are placed) detailing the esAmated amount of soil
hauled and a summary of any tesAng performed.

• Date, project name
• Weather informaAon
• A descripAon of all ongoing construcAon for the month
• Areas of nonconformance/correcAve acAons, if any
• Record of any site visitors
• Signature of Landfill Manager

C. Problem IdenAficaAon / CorrecAve AcAon – The problem idenAficaAon / correcAve acAon
form is to be uAlized to idenAfy and document porAons of the construcAon that do not meet
project specificaAons. The problem idenAficaAon / correcAve acAon form also documents the
correcAve acAon associated with every problem idenAfied during construcAon. The Landfill
Manager and Engineer will be responsible for filling out the Problem IdenAficaAon / CorrecAve
AcAon form.

D. Photographs

ConstrucAon acAviAes may be photographed. Photographs could include any significant
problems encountered and correcAve acAons, and document construcAon progress. The

9 | Page

photographs will be idenAfied by locaAon, date, and a brief narraAve of the subject of the
photograph. The Landfill Manager will be responsible for taking and cataloging construcAon
photographs.

3.2 Final Construc6on Report

At the compleAon of each Stage of the final cover construcAon, the Landfill Manager will submit
a final construcAon documentaAon to the Engineer. The Engineer will review the construcAon
documentaAon, perform a post-construcAon site visit and prepare a construcAon report that will
document that the final cover has been constructed in compliance with the construcAon drawings
and specificaAons.

At a minimum, the final construcAon report will contain:

• A summary of major construcAon acAviAes
• A summary of field tests
• Sampling and tesAng locaAons
• As-built record drawings (if prepared)
• Photographs of the final cover construcAon

Once the Engineer finalizes the construcAon report that deems that the documentaAon is
complete and that the work product has met the intent of the design, he will issue a le`er to the
DWMRC. The le`er to the DWMRC will contain a statement of compliance with the construcAon
drawings and specificaAons signed and stamped by a professional engineer registered in Utah.

The post construcAon as-built survey drawing (if uAlized) will present the locaAon of all tests
performed associated with the cover construcAon. The post construcAon survey (if uAlized) will
be included in the final construcAon report and submi`ed to the UDWMRC.
