 Form 10-K for the Fiscal Year ended December 31, 2024

 Filed February 13, 2025

 File No. 001-34370

 Ladies and Gentlemen:

 This letter responds to the written comment that
the Company received from the Staff of the Division of Corporation Finance (the " Staff ") of the U.S. Securities and
Exchange Commission (the " Commission ") on September 8, 2025. For your convenience, the Company's response is
prefaced by the Commission's comment in bold text. All capitalized terms used but not defined herein shall have the meanings given
to them in the Company's Form 10-K for the Fiscal Year Ended December 31, 2024.

 Form 10-K for the Fiscal Year ended December
31, 2024

 Financial Statements

 Note 13 – Commitments and Contingencies, page 122

 Legal Proceedings, page 123

 1.
 We note that you identify six matters of litigation on pages 123-129 that could have a material adverse effect on your business,
financial condition, results of operations or cash flows, although for each you state that you are "not able to determine the likelihood
of any outcome." We also note that you include various risk factors concerning these matters under Item 1A. For example, on page
35, you reference environmental problems and state that these "could result in substantial remediation costs, regulatory enforcement
actions and related fines or potential litigation," and on page 46, you reference litigation and governmental proceedings and state
 "the possible outcomes or resolutions to these matters could include adverse judgments or settlements, either of which could require
substantial payments, adversely affecting our consolidated financial condition, results of operations and cash flows."

 Please expand your disclosures to clarify the extent of any accounting
that has been reflected in your financial statements for such matters, to include the extent of any accruals that you have made
and the periods impacted, also to specify the range of reasonably possible additional loss for each matter, or to clarify if such an
estimate is not possible in which case also specify the amounts of any claims for damages and penalties, where such claims have been
quantified by the counterparties.

 Given the significant level of estimation uncertainty that appears
to be characteristic of the difficulty you express in understanding the prospects for resolution, it appears that you should also
expand your disclosures in (i) MD&A to include qualitative and quantitative information regarding the estimation uncertainty and the
impact the critical accounting estimate has had, or is reasonably likely to have, on your financial condition and results of operations,
to address the critical accounting estimate disclosure requirements in Item 303(b)(3) of Regulation S-K, and (ii) Note 3 to your financial
statements to describe the policy that you have formulated, based on the guidance in FASB ASC 450-20, as to the accounting and disclosures
related to loss contingencies, to comply with FASB ASC 235-10-50-1.

 Response:

 The Company acknowledges the Staff's comment.
FASB ASC 450-20-50-4 requires, if a loss contingency is reasonably possible, disclosure of the nature of the contingency and an estimate
of the possible loss or range of loss or a statement that such an estimate cannot be made. The Company respectfully confirms that in
each of the matters referenced on pages 123 through 129 of its Annual Report on Form 10-K for the year ended December 31, 2024 (the " Annual
Report "), the Company is unable to estimate a range of potential losses due to the early stage of proceedings, factual disputes,
uncertainty regarding the plaintiffs' or relevant government agencies' damages or penalties sought, and the inherent uncertainty
in the legal process. In addition, except to the limited extent noted below, the respective plaintiffs and state or federal governmental
agencies, as applicable, have not specified the damages and penalties being sought, such that the Company is currently unable to specify
the amounts of claims for damages and penalties. We address each of the six items in the Annual Report in more detail below, with a description
of certain supplemental disclosures we will make in the future, where applicable, in order to address the Staff's comment. The
Company confirms that it will continue to review and assess potential exposure to litigation in each period, and will update its periodic
disclosures accordingly, including providing an estimate of possible loss in accordance with ASC 450-20-50-3 to 50-4 when such information
is available.

 · Several distinct matters are summarized under the caption "Jefferson Parish, Louisiana
 Landfill Litigation". Regarding the matter referred to in the Annual Report as the Addison action, we note that our
 subsequently filed Quarterly Reports on Form 10-Q have updated this disclosure to report that the Company entered into a settlement
 agreement with the plaintiffs in June 2025, for an amount not material to the Company's financial statements, and that the
 court has dismissed the matter with prejudice. Regarding the matter referred to in the Annual Report as the Ictech-Bendeck action,
 we draw your attention to the statement on page 124 of the Annual Report that the putative class plaintiffs sought unspecified
 damages. We further draw your attention to the Company's subsequently filed Quarterly Reports on Form 10-Q, which have updated
 this matter to report that after the court denied class status, the Company reached an agreement in principle in July 2025 with the
 five individual remaining plaintiffs to settle these matters for an amount not material to the Company's financial statements,
 and the court dismissed the action without prejudice pending finalization of that settlement agreement. In light of the settlements
 noted above, the Company does not believe that additional disclosure relating to the accounting for the Addison or Ictech-Bendeck
 actions is warranted.

 · The matters described under the caption "Chiquita Canyon LLC Lawsuit against Los Angeles County" relate to the terms of
a conditional use permit for our subsidiary Chiquita Canyon LLC authorizing the continued use and expansion of the Chiquita Canyon Landfill.
As the Annual Report describes, CCL and the County entered into a settlement agreement in 2022 outlining agreed-upon modifications to
CCL's CUP. As noted in the Annual Report, the County failed to present the CUP modification to the County's Regional Planning
Commission for approval as contemplated by the settlement agreement by the end of 2024 or provide a viable alternative solution to address
the severe tonnage restrictions that applied to disposal operations absent the CUP modification. As a result, maintaining ongoing operations
at the CC Landfill was no longer economically viable and CCL closed active waste disposal operations at the end of 2024. In light of these
developments, the status of the litigation over the CUP as well as the modified CUP itself is subject to substantial uncertainty. The
matter does not involve a claim for damages, however, and is unlikely to involve a significant payment to the County under its current
posture. The Company does not believe that additional disclosure relating to the accounting for this matter is warranted.

 · The matter described under the caption "December 11, 2017 Notice of Violation Regarding Certain CUP Conditions" in the
Annual Report is a lawsuit filed by CCL against Los Angeles County and its Department of Regional Planning challenging a notice of violation
issued by the County related to a fee imposed under the CUP described above. CCL subsequently paid the fee under protest, along with an
administrative penalty and a noncompliance fee. As such, it is unlikely to involve a significant additional payment to the County under
its current posture. The Company does not believe that additional disclosure relating to the accounting for this matter is warranted.

 · The matters under the caption "Elevated Temperature Landfill Event" relate to certain
 notices of violation, summaries of violation or findings of violation by the South Coast Air Quality Management District, the Los
 Angeles Regional Water Quality Control Board, the California Department of Toxic Substances Control and the U.S. Environmental
 Protection Agency. Except to the limited extent noted below, none of these NOVs, SOVs, or FOV quantify penalties sought by the
 relevant governmental agency, other than in certain cases outlining the potential maximum amounts permitted to be sought by the
 agency under the applicable statutes. In late 2024, CCL and SCAQMD engaged in preliminary settlement discussions that included
 quantification of potential payments for a portion of the SCAQMD NOVs-in amounts not material to the Company's financial
 statements-but the parties remained far apart. CCL subsequently closed the CC Landfill effective January 1, 2025, and no
 discussions have taken place since. The Company's statement that it is unable to determine the likely penalties that the
 regulatory agencies will seek remains accurate. In future filings, if we remain unable to reasonably estimate the possible loss or
 range of loss, we will also clarify that we are unable to do so, and, if applicable, will indicate the penalties sought.

 · The matters identified under the caption "Chiquita Canyon Landfill Civil Litigation" in
 the Annual Report are all in the preliminary, pre-discovery phase. The Company has indicated in its filings the nature of the
 allegations. None of the plaintiffs has to date quantified their claims or damages in their complaints or other filings. In future
 filings, if we remain unable to reasonably estimate the possible loss or range of loss, we will also clarify that we are unable to
 do so, and, if applicable, will indicate the damages sought.

 · The matter identified as "County of Los Angeles Litigation" remains in a preliminary stage. The Company's existing
disclosure has outlined the nature of the claims alleged. The County has not quantified a claim for damages in its pleading. We note the
Company's statement on page 129 of the Annual Report that the Company is unable to determine the potential penalty amount that the
County may seek. The pleading simply references two sources of potential statutory penalties. In future filings, if we remain unable to
reasonably estimate the possible loss or range of loss, we will also clarify that we are unable to do so, and, if applicable, will indicate
the damages sought.

 We also acknowledge the Staff's
comment on critical accounting estimate disclosure requirements in Management's Discussion and Analysis under Item 303(b)(3) of
Regulation S-K, and on the significant accounting policy disclosure under Note 3 to the audited financial statements in our Annual Report.

 In future filings, we will include disclosure in "Management's Discussion and Analysis of Financial Condition and Results of Operations"
in our annual reports on Form 10-K, substantially as set forth below:

 Loss
Contingencies . We record accruals for various contingencies including legal exposures as they arise in the normal course of
business. We determine whether to disclose and accrue for loss contingencies based on an assessment of whether the risk of loss is remote,
reasonably possible, or probable, and if it can be reasonably estimated. Our assessment is developed in consultation with our internal
and external counsel and other advisors and is based on an analysis of possible outcomes under various strategies. Loss contingency assumptions
involve judgments that are inherently subjective and can involve matters that are in litigation, which, by its nature, is unpredictable.
We believe that our qualitative and quantitative assessment of the probability of loss contingencies is reasonable, but because of the
subjectivity involved and the unpredictable nature of the subject matter at issue, our assessment may prove ultimately to be incorrect,
which could harm our financial condition, operating results, or cash flow.

 In response to the Staff's
comment, the Company will revise Note 3 (Summary of Significant Accounting Policies) to the audited financial statements in future filings
of our annual reports on Form 10-K to include a description of its accounting policy for loss contingencies, substantially as set forth
below:

 Loss Contingencies

 In the normal course of our
business we are subject to various litigation, claims, and regulatory matters. In accordance with authoritative guidance on accounting
for contingencies, we disclose or accrue for loss contingencies based on an assessment of whether the risk of loss is remote, reasonably
possible, or probable, and whether the amount can be reasonably estimated. We accrue a liability when a loss is both probable and reasonably
estimable. If a loss is reasonably possible but not estimable, we disclose the nature of the contingency and, if known, the range of potential
loss or a statement that such an estimate cannot be made. Management develops its assessment based on information available to us and
an analysis of possible outcomes under various strategies.
