PART 1 – GENERAL REQUIREMENTS
1.1 Purpose

The purpose of this plan is to describe the quality assurance procedures to be utilized during the
construction of the final soil cover over the Logan City Sanitary Landfill (Logan Landfill). The
Logan Landfill will be closed in a series of phases starting the summer of 2020. The primary
goals of the quality assurance program are to:

• Determine if proper construction techniques, materials, and procedures are used.
• Determine if the intent of the construction documents is met.
• Identify construction problems and provide a method for resolution of any problem.
• Document the construction activities.

Upon the completion of each final cover phase construction; a final construction documentation
package will be prepared and submitted to the State of Utah Division of Waste Management and
Radiation Control (UDWMRC).

1.2 Document Format

The Quality Assurance Plan is divided into three sections to identify; 1) the general information
and personnel associated with the project; 2) the detailed requirements of the quality assurance
program; and 3) the documentation and record keeping associated with the construction.

1.3 Definitions

construction and minimize the potential for errors. The Landfill Manager will conduct and
document all meetings.

A. Preconstruction Meeting – A preconstruction meeting will be held with representatives
from the Owner, UDWMRC staff, the Engineer, and the Contractor (if selected prior to
the preconstruction meeting). The “for construction” documents, quality assurance plan,
testing requirements, reporting procedures, and overall project responsibilities for all
parties will be reviewed at the meeting.

B. Progress Meetings – Progress meetings are not anticipated. Progress meetings will be
scheduled as necessary. If a progress meeting is scheduled, representatives from the
Owner, State, the Engineer, and Contractor will attend. The purpose of the progress
3
meetings will be to discuss progress, identify problems (and corrective actions), review
test data, and coordinate work activities including testing.

C. Postconstruction Meeting – A postconstruction meeting will be held with representatives
from the Owner, State, the Engineer, and the Contractor (if available). The final cover
construction work and documentation will be reviewed and compared to the Quality
Assurance Plan for completeness. If adequate documentation is not included, test pits
may need to be excavated to demonstrate cover soil thickness.

1.5 Responsibilities of Personnel

A. Responsibilities of the Landfill Manager – The Landfill Manager is the primary Owner’s
representative on the project. The Landfill Manager defines the overall project scope and
is responsible for the implementation of all construction related activities. The Landfill
Manager is the point of contact for all communications. The Landfill Manager reports to
the Environmental Director at the City of Logan.

the oversight of all landfilling activity in the State. UDWMRC is responsible to review
and approve the quality assurance plan developed by the engineer. The UDWMRC will
be available for clarification of the approved plan or State related concerns if necessary.

1.6 Construction Documents

A. QA/QC Plan – Appendix A contains the Class I Landfill Final Cover QA/QC Plan for the
first Phase of the final cover construction at the Logan Landfill. The QA/QC Plan
includes the construction drawings as well as revegetation specifications. A
preconstruction survey of the existing landfill cover (in the area to be closed) may be
utilized to document the preconstruction grade and serve as a basis for a post construction
4
survey utilized to demonstrate cover thickness. Alternatively, Contractor may elect to
install grading stakes to indicate required cover thickness.

B. Specifications – The only project specifications for the cover construction are presented
in Part 2 and on the drawings in Appendix A.

C. Forms – The forms required for use on the first Phase of the final cover project are
included in Appendix A.
5

PART 2 – CONSTRUCTION QUALITY ASSURANCE

2.1 Introduction

This section describes the monitoring and testing that will be performed to assure that the final
cover construction meets the specified requirements.

2.2 Material Evaluation

A. Testing – Soil sources will be identified prior to placement. No specific testing of the
soils to be utilized in the construction will be required. The soil to be utilized for the first
Phase of the final cover at the Logan Landfill will come from the soils excavated during
the construction of the new wastewater plant.

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

2.3 Construction Testing

A. Test Procedures – Soil will be tested according to the tests identified in Table 1.

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

2.4 Monitoring Requirements

The monitoring requirements will include verification of final cover thickness.

2.5 Documentation and Control of Nonconformance

2.5.1 Observation of Nonconformance

Whenever a nonconformance (cover thickness less than 24”) is discovered the
Landfill Manager will either document the location of the nonconformance (to be
corrected at a future date) or 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 construction
process, product, documentation, or elsewhere, the Landfill Manager will
determine the extent of the nonconformance. The extent of the deficiency may be
determined by additional sampling, testing, observations, review of records, or
any other means deemed appropriate.

6
2.5.3 Documenting Nonconformance

All nonconformances (observed but not corrected) will be documented in writing
on a Problem Identification / Corrective Action form. The documentation will
occur immediately upon determining the extent of the nonconformance.

2.5.4 Corrective Action

Since the only criterial item required for final cover construction documentation is
cover thickness; the prescribed corrective action is to add additional soil until a
minimum of 2’ of soil cover is documented.

For those nonconformances not relating to cover thickness (drainage features), the
engineer will be asked to review the proposed corrective action. The UDWMRC
will be notified of all corrective actions (other than soil thickness) prior to
implementation.

2.5.5 Verification of Corrective Actions

The Engineer and UDWMRC personnel will verify all corrective actions. The
verification will be accomplished by site observations, depth testing (test pits),
and photographs. Verification of corrective actions will be made during the
postconstruction meeting. Written documentation of the corrective measures will
be made by the Engineer on the second page of the Problem Identification /
Corrective Action form.

2.6 Construction Surveys

A pre and post-construction survey may be performed by the Owner to document final cover
geometry and thickness. If grading stakes are utilized, construction surveys are not required.

2.7 Revegetation

Contractor to perform revegetation as detailed on the drawings in Appendix A.
7

PART 3 – DOCUMENTATION

3.1 Recordkeeping

The quality assurance plan relies on the observations, testing, and associated documentation of
all construction activities. The documentation activities will be performed by the Landfill
Manager.

A. Daily Record of Construction Progress – Due to the anticipated method and rate of
construction; daily construction reports may not be utilized. Soil will be moved by the
Contractor and potentially stockpiled on the existing landfill for several days before being
graded down the landfill slopes. Once enough material has been stockpiled; the
Contractor will grade the stockpiled material out to form the 2-foot thick final cover.

B. Weekly Record of Construction Progress – If the final cover construction is done at a
relatively slow pace; the Landfill Manager will fill out weekly construction records
(during the weeks that the final soil cover materials are placed) detailing the number of
loads of soil hauled and a summary of test performed.

Date, project name
Weather information
A description of all ongoing construction for the week
Areas of nonconformance/corrective actions, if any
Record of any site visitors
Signature of Landfill Manager

C. Problem Identification / Corrective Action – The problem identification / corrective
action form is to be utilized to identify and document portions of the construction that do
not meet project specifications. The problem identification / corrective action form also
documents the corrective action associated with every problem identified during
construction. The Landfill Manager and Engineer will be responsible for filling out the
Problem Identification / Corrective Action form.

D. Photographs

Construction activities will be photographed. Photographs will include any significant
problems encountered, show areas of potential corrective actions, and document
construction progress. The photographs will be identified by location, date, and a brief
narrative of the subject of the photograph. The Landfill Manager will be responsible for
taking and cataloging construction photographs.

3.2 Final Construction Report

At the completion of each Phase of the final cover construction, the Landfill Manager will
submit a final construction report to the Engineer. This report will document that the final cover
has been constructed in compliance with the construction drawings and specifications.

8
At a minimum, the final construction report will contain:

• A summary of major construction activities
• A summary of field tests (if any)
• Sampling and testing location drawings (if any)
• As-built record drawings (if prepared)
• Photographs of the final cover construction

Once the Engineer reviews the construction report from the Landfill Manger and deems that the
documentation is complete and that the work product has met the intent of the design, he will
issue a letter to the UDWMRC. The letter to the UDWMRC will contain a statement of
compliance with the construction drawings and specifications signed and stamped by a
professional engineer registered in Utah.

The post construction as-built survey drawing (if utilized) will present the location of all tests
performed associated with the cover construction. The post construction survey (if utilized) will
be included in the final construction report and submitted to the UDWMRC.

Memo
To: Doug Taylor
From: Brett Mickelson
cc: Tyler Richards
Date: 5 17 2022
Re: Soil Approval / Logan Landfill Closure Approval
Doug,
IGES has performed testing on additional soil samples that Logan City would like to utilize in the
construction of the Phase 3 final cover at the Logan Landfill. The soil samples tested all classify as either
CL (inorganic clays of low to medium plasticity) or CH (inorganic clays of high plasticity or fat clays) with
Plasticity Index ranging between 26 and 30. The bulk of the soils were finer that a #200 sieve with no
less than 89.1 percent passing the #200 sieve. The soils tested for use in the Phase 3 cover will meet the
requirements of R315-303-3(4). The laboratory testing results area are attached.

Since the construction of the Phase 3 final cover is exactly the same as the Phase 2 and Phase 1 final
covers (with the slight difference in the cover soils), Logan City would like to utilize the previously
submitted Phase 1 QA/QC plan and applicable portions (cover detail and specifications) of the Phase 1
Closure Plan. The contractor that installed the Phase 1 and Phase 2 covers is scheduled to construct the
Phase 3 cover.

Additionally, a new aerial topography survey for the Logan Landfill has been completed to aid in the
Phase 3 cover construction. The updated topography as well as the final cover contours and conceptual
closure sequence is attached for your review and approval.

If you have questions or comments regarding this preliminary assessment of the pond capacity or
recommendations presented above, please call at your earliest convenience.

Respectfully,

Brett Mickelson, P.E.

RE: Logan City Class I Landfill Phase III Final Cover Approval
SW097

Dear Mr. Hamud:

The Division of Waste Management and Radiation Control has received and reviewed the Memo from Brett
Mickelson, of IGES, to Doug Taylor, dated May 17, 2022, (DSHW-2022-011481) requesting additional soils
be approved for the Phase III final soil cover for the Logan Landfill. As the memo and test data suggest,
these soils are like previously approved materials for the Phase I and II final covers.

The request to use these soils for Phase III closure at the Logan City Landfill as well as the request to use the
previously utilized QA/QC plan for Phase I and Phase II closures is hereby approved.

Please notify our office when work begins so we can conduct oversight activities as stipulated in the Permit.

If you have any questions, please call Doug Taylor at [phone].

Sincerely,

Douglas J. Hansen, Director
Division of Waste Management and Radiation Control

Date: 1 9 2023
Re: Soil Approval / Logan Landfill Closure Approval
Doug,

IGES has performed testing on additional soil samples that Logan City would like to utilize in the
construction of the final cover at the Logan Landfill. The soil samples tested all classify as either MH
(inorganic elastic silt of high plasticity) or CH (inorganic clays of high plasticity or fat clays) with Plasticity
Index ranging between 17 and 47. The bulk of the soils were finer that a #200 sieve with no less than
68.1 percent passing the #200 sieve on any of the soil tested. The soils tested for use in the final landfill
cover will meet the requirements of R315-303-3(4). The laboratory testing results area are attached.

If you have questions or comments regarding this preliminary assessment of the pond capacity or
recommendations presented above, please call at your earliest convenience.

Respectfully,

Brett Mickelson, P.E.
IGES, Inc.

RE: Logan City Class I Landfill Final Cover Soils Approval

Dear Mr. Hamud:

The Division of Waste Management and Radiation Control has received and reviewed the Memo from
Brett Mickelson, of IGES, to Doug Taylor, dated January 9, 2023, (DSHW-2023-000482) providing test data
and requesting approval for soils to be used to construct the final cover for the Logan Landfill. As the memo
and test data suggest, these soils are similar to those soils previously approved for the final cover at the
Logan Landfill.

The request to use these soils for final cover at the Logan City Landfill is hereby approved.

Please notify our office when work begins so we can conduct oversight activities as stipulated in the Permit.

If you have any questions, please call Doug Taylor at [phone].

Sincerely,

Douglas J. Hansen, Director
Division of Waste Management and Radiation Control
