Guarantor and Non-Guarantor Subsidiaries Financial Information [Abstract] |
GUARANTOR AND NON-GUARANTOR SUBSIDIARIES FINANCIAL INFORMATION | GUARANTOR AND NON-GUARANTOR SUBSIDIARIES FINANCIAL INFORMATION The 2020 Notes and the 2021 Notes (collectively, the "Notes") are guaranteed by substantially all of the Company’s subsidiaries organized in the United States. Each guarantor for the Notes is a 100% owned subsidiary of Clean Harbors, Inc. and its guarantee is both full and unconditional and joint and several. The guarantees are, however, subject to customary release provisions under which, in particular, the guarantee of any domestic restricted subsidiary will be released if the Company sells such subsidiary to an unrelated third party in accordance with the terms of the indentures which govern the Notes. The Notes are not guaranteed by the Company’s subsidiaries organized outside the United States. The following supplemental condensed consolidating financial information for the parent company, the guarantor subsidiaries and the non-guarantor subsidiaries, respectively, is presented in conformity with the requirements of Rule 3-10 of SEC Regulation S-X (“Rule 3-10”).

- Definition This element represents the disclosure of the condensed financial statements (balance sheet, income statement and statement of cash flows), normally using the registrant (parent) as the sole domain member. If condensed consolidating financial statements are being presented, other domain members (in addition to parent) such as guarantor subsidiaries, non-guarantor subsidiaries, and the consolidation eliminations, will be included in order that the respective monetary amounts for each of the domains will aggregate to the respective amounts on the consolidated financial statements. The line items are the various captions used to compile the condensed financial statements. Using extensions, most, if not all, of the elements representing condensed financial statement captions will be the same as those used for the consolidated financial statements captions. + References No definition available. + Details
