PART 1 – GENERAL REQUIREMENTS
1.1 Purpose
The purpose of this plan is to describe the quality assurance procedures to be uClized during the
construcCon of the final soil cover at Bayview Landfill (Bayview). Bayview will be closed in a series
of phases which will be completed as large porCons of the landfill are brought to design elevaCon.
The primary goals of the quality assurance program are to:

• Ensure that the permit requirements are met.
• Ensure proper construcCon techniques and materials are used.
• IdenCfy construcCon problems and provide a method for resoluCon of any problem.
• Document the soil cover construcCon and all associated laboratory tesCng.
Upon the compleCon of each final cover phase construcCon; a final construcCon documentaCon
package will be prepared and submiZed to the State of Utah Division of Waste Management and
RadiaCon Control (UDWMRC) for approval.

1.2 Document Format
The Quality Assurance Plan is divided into three secCons to idenCfy; 1) the general informaCon
and personnel associated with the project; 2) the detailed requirements of the quality assurance

1.4 Mee6ngs
PreconstrucCon and postconstrucCon meeCngs may be held in associaCon with each phase of
the final cover construcCon at Bayview. The meeCngs are intended to facilitate the cover
construcCon and minimize the potenCal for errors. The Landfill Manager will conduct and
document all meeCngs that are held. MeeCngs may be beneficial to each construcCon phase but
are not required.

A. PreconstrucCon MeeCng – A preconstrucCon meeCng may be held with representaCves
from the Owner, DWMRC staff, the Engineer, and the ConstrucCon Team. The “for construcCon”

documents, quality assurance plan, tesCng requirements, reporCng procedures, and overall
project responsibiliCes of all parCes will be reviewed at the meeCng.

B. Progress MeeCngs – Progress meeCngs are not anCcipated. Progress meeCngs will be
scheduled as necessary. If a progress meeCng is scheduled, representaCves from the Owner,
DWMRC staff, the Engineer, and ConstrucCon Team may aZend. The purpose of the progress
meeCngs will be to discuss progress, idenCfy problems (and correcCve acCons), review test data,
and coordinate work acCviCes including tesCng.

C. PostconstrucCon MeeCng – A postconstrucCon meeCng may be held with representaCves
from the Owner, DWMRC staff, the Engineer, and the ConstrucCon Team. The final cover
construcCon work and documentaCon will be reviewed and compared to the Quality Assurance
Plan for completeness. If adequate documentaCon is not included, addiConal test pits and
gradaCon tesCng may need to demonstrate cover soil thickness and soil properCes.

the quality assurance plan developed by the engineer. The UDWMRC will be available for
clarificaCon of the approved plan or State related concerns if necessary.

1.6 Construc6on Documents
A. ConstrucCon Drawings – Appendix A will contain the plans for the individual Phases of the
final cover construcCon at Bayview under this QA/QC Plan. A preconstrucCon survey of the
exisCng landfill cover (in the area to be closed) may be uClized to document the preconstrucCon
grade and serve as a basis for a post construcCon survey uClized to demonstrate cover thickness.
AlternaCvely, Bayview personnel may elect to install grading stakes to indicate required cover
thickness. Appendix A will be completed for each final cover Phase.

B. SpecificaCons – The only project specificaCons for the cover construcCon is presented in
Part 2.

C. Forms – The forms required for use on each Phase of the final cover construcCon projects
are included in Appendix B.

PART 2 – CONSTRUCTION QUALITY ASSURANCE

2.1 Introduc6on
This secCon describes the monitoring and tesCng that will be performed to assure that the final
cover construcCon meets the specified requirements.

2.2 Material Evalua6on
A. TesCng – Final cover soil sources will be idenCfied, tested, documented, and preapproved
prior to placement. If final cover soil sources are not preapproved, gradaCon tesCng for the final
cover soil will be performed at one gradaCon test per 5,000 cubic yards of final cover soils placed.
No addiConal tesCng of the soils to be uClized in the construcCon will be required other than to
document that a minimum of 34-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 – Soil will be tested according to the tests idenCfied in Table 1.

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

acre of final cover.
Landfill manager may require more tests based on test results and/or field condiCons.
2.4 Monitoring Requirements
The monitoring requirements will include verificaCon of final cover thickness.

2.5 Documenta6on and Control of Nonconformance
2.5.1 ObservaCon of Nonconformance

Whenever a nonconformance (cover thickness less than 34”) is discovered the Landfill Manager
will either document the locaCon of the nonconformance (to be corrected at a future date) or
have the ConstrucCon 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 construcCon process, product,
documentaCon, or elsewhere, the Landfill Manager will determine the extent of the

7 | Page

nonconformance. The extent of the deficiency may be determined by addiConal sampling,
tesCng, observaCons, review of records, or any other means deemed appropriate.

2.5.3 DocumenCng Nonconformance

All nonconformances (observed but not corrected) will be documented in wriCng on a Problem
IdenCficaCon / CorrecCve AcCon form. The documentaCon will occur immediately upon
determining the extent of the nonconformance.

2.5.4 CorrecCve AcCon

Since the only criterial items required for final cover construcCon documentaCon is cover soil
gradaCon (which will be preapproved prior to placement) and final cover thickness; the
prescribed correcCve acCon is to add addiConal soil unCl a minimum of 34-inches of soil cover is
documented.

For those nonconformances not relaCng to cover thickness (drainage features, revegetaCon, etc.),
the engineer will be asked to review the proposed correcCve acCon. The UDWMRC will be
noCfied of all correcCve acCons (other than soil thickness) prior to implementaCon.

2.5.5 VerificaCon of CorrecCve AcCons

The Engineer and DWMRC personnel will verify all correcCve acCons. The verificaCon will be
accomplished by site observaCons, depth tesCng (test pits), addiConal laboratory tesCng of cover
soils, and photographs. VerificaCon of correcCve acCons may be made during the
postconstrucCon meeCng. WriZen documentaCon of the correcCve measures will be made by
the Engineer on the second page of the Problem IdenCficaCon / CorrecCve AcCon form.

2.6 Construc6on Surveys
A pre and post-construcCon survey may be performed by the Owner to document final cover
geometry and thickness. Test pits may be excavated to confirm survey data or to provide
documentaCon of final cover thickness if surveys are not uClized or if survey data is suspect.

2.7 Revegeta6on
During the final grading of the landfill slopes, the orientaCon of the dozer will be uphill and result
in grouser marks that are perpendicular to the slope. Those ridges lej on the slope by the
equipment tracks will also minimize slope erosion by providing interrupCon to the surface water
flow.

8 | Page

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 roads will
prohibit water from flowing from the top of the landfill down the side slopes by direcCng the
water laterally away from the final cover. AddiConal access roads may be constructed to aid in
final cover access and to minimize erosion as necessary.

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

Reclama^on Seed Mix (Per Acre)

Pounds PLS
Sand Drop Seed 0.5
Alkali Sacaton 1.5
Blue Grama 3.5
Blue Bunch Wheat Grass 17.5
Indian Rice Grass 17.5
Sandberg Blue Grass 3
Sheep Fescue 4
Slender Wheat Grass 16.25
Stream Bank Wheat Grass 16.25
Western Wheat Grass 20

The Owner may elect to coordinate revegetaCon efforts with local agricultural personnel or Utah
State University Extension office personnel to select a different seed mix or revegetaCon efforts
if iniCal revegetaCon is not adequately robust.
PART 3 – DOCUMENTATION

3.1 Recordkeeping

The quality assurance plan relies on the observaCons, tesCng, and associated documentaCon of
all construcCon acCviCes. The documentaCon acCviCes will be performed by the Landfill
Manager.

A. Daily Record of ConstrucCon Progress – Due to the anCcipated method and rate of
construcCon; daily construcCon reports will not be uClized. Soil will be moved by the
ConstrucCon Team and potenCally stockpiled on the exisCng landfill for several weeks/months
before being graded down the landfill slopes or placed in a final configuraCon. Once enough soil

9 | Page

has been stockpiled and the topography of the waste has been determined; the landfill operators
will grade the stockpiled material out to form the minimum 34-inch-thick final cover.

B. Weekly/Monthly Record of ConstrucCon Progress – Since the final cover construcCon will
be done at a relaCvely slow pace; the Landfill Manager may fill out weekly or monthly
construcCon record (during the weeks or months that the final soil cover materials are placed)
detailing the esCmated amount of soil hauled and a summary of any tesCng performed.

• Dates covered
• A descripCon of all ongoing construcCon for the week/month
• EsCmates of soil cover placed
• Areas of nonconformance/correcCve acCons, if any
• RevegetaCon acCviCes
• Signature of Landfill Manager

C. Problem IdenCficaCon / CorrecCve AcCon – The problem idenCficaCon / correcCve acCon
form is to be uClized to idenCfy and document porCons of the construcCon that do not meet
project specificaCons. The problem idenCficaCon / correcCve acCon form also documents the
correcCve acCon associated with every problem idenCfied during construcCon. The Landfill
Manager and Engineer will be responsible for filling out the Problem IdenCficaCon / CorrecCve
AcCon form if necessary.

D. Photographs

ConstrucCon acCviCes may be photographed. Photographs may include general construcCon
acCviCes, problems encountered, correcCve acCons, test pits, and other construcCon
documentaCon as necessary. The photographs will be idenCfied by locaCon, date, and a brief
narraCve of the subject of the photograph. The Landfill Manager will be responsible for taking
and cataloging construcCon photographs.

3.2 Final Construc6on Report

At the compleCon of each Phase of the final cover construcCon, the Landfill Manager will submit
a final construcCon documentaCon to the Engineer. The Engineer will review the construcCon
documentaCon, perform a post-construcCon site visit and prepare a construcCon report that will
document that the final cover has been constructed in compliance with the construcCon drawings
and specificaCons.

10 | Page

At a minimum, the final construcCon report will contain:

• A descripCon of final soil cover placed
• Preapproved soil gradaCon tesCng results
• LocaCons and photographs of test pits
• As-built record drawings (if prepared)
• Photographs of the final cover construcCon

Once the Engineer finalizes the construcCon report that deems that the documentaCon is
complete and that the work product has met the intent of the design, he will issue a leZer to the
DWMRC. The leZer to the DWMRC will contain a statement of compliance with the construcCon
drawings and specificaCons signed and stamped by a professional engineer registered in Utah.

The post construcCon as-built survey drawing (if uClized) will present the locaCon of all tests
performed associated with the cover construcCon. The post construcCon survey (if uClized) will
be included in the final construcCon report and submiZed to the UDWMRC.

Subject: Source Material Investigation
South Utali VaUey Landfill (Baj-view LandFiIl)
Utah County, Utah
Dear Mr. Wamer:
In conjunction with KJeinfelder's report dated July I, 2003, we are providing tlie following
information to summarize the findings of our report.
Identification of Suitable Material
Based on laboratory testing and modeling, as presented in Kleinfelder's Meteoric Water Infiltration
Study, one of the predominant soils at Bay\'iew LandfiU has been identified as an acceptable
material for the CeU 1 protective cap. This soil is classified as a silty sand (SM) to sandy silt (ML),
and is generally olive brown in color. Based on numerous tests performed on this proposed
capping material, this material can generally be characterized by the following grain-sizes:
Sieve Size
No. 4 (1/4 inch)
No. 40
No. 60
No. 200
Percent Passing
95 - 100%
70-100%
60-95%
30-70%
Other materials present at the site differ significantly from this gradation criteria and are generally
easy to screen out based on field logging and gradation tests.
Location of Suitable Material
The proposed suitable cap material was found in the stockpile north of Cell 1 and in the floor ofthe
excavation for Cell 2. In the Uiree borings drilled in the stockpile north of Cell 1, we found one 5-
foot thick layer in B-3, and a few other pockets of material tlial did not meet these specifications.
We investigated the materials immediately below the stockpile north of Cell 1 and beneath the
dune sand south of Cell 2 and found only^some pockets of material suitable for construction ofthe
protective cap layer in those locations.

Two test pits excavated within Cell 2 contained 6 to 7 feet ofthe suitable cap material.
We recommend tliat lenses or pockets encountered within the stockpile or under Cell 2 that do not
fall within the gradation criteria identified above be excluded fi'oin use in tiie protective cap layer
unless further testing and analysis is performed to evaluate their suitability.
