(a) | In 2021, the increase in our landfill liabilities for revisions in estimates and interest rate assumptions was $33 million. The increase in our landfill liabilities in 2022 is primarily due to inflationary cost pressures that are expected to impact costs over the remaining landfill lives.
Our recorded liabilities as of December 31, 2022 include the impacts of inflating certain of these costs based on our expectations of the timing of cash settlement and of discounting certain of these costs to present value. Anticipated payments of currently identified environmental remediation liabilities, as measured in current dollars, are $31 million in 2023, $43 million in 2024, $29 million in 2025, $19 million in 2026, $16 million in 2027 and $76 million thereafter.
