As a result of the outbreak, many companies have experienced disruptions in their operations, workforce and markets served, including a significant reduction in the demand for petroleum-based products. The Company's businesses and operations began being adversely impacted by effects of COVID-19 in March of 2020 when circumstances surrounding and responses to the pandemic, including stay-at-home orders, began to materialize in North America. These disruptions are expected to have a significant adverse impact on the Company's operating results during the second quarter of 2020 and the remainder of the year. The full extent of the COVID-19 outbreak and changes in demand for oil and the impact on the Company&#8217;s operations is uncertain. A prolonged disruption could have a material adverse impact on financial results and business operations of the Company.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:46px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In addition and in response to the COVID-19 outbreak, the Company has seen increased demand in emergency response services. Specifically the Company is addressing the safety of its customers and communities by providing contagion decontamination services. In conducting these services, employee safety is paramount and the Company has been able to provide appropriate personal protective equipment and support to those performing these services.</span></div></ix:continuation><div><a id="sFA5F5E6F14E1536CA6696BDC66E9FC36"></a></div><div style="line-height:120%;padding-bottom:10px;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-weight:bold;">(2)&#160;<ix:nonNumeric contextRef="FD2020Q1YTD" name="us-gaap:SignificantAccountingPoliciesTextBlock" id="TextSelection-BB94EE879DB15AC3A960F909AE2DA3B3-0-wk-Fact-8F32EBDC1B60534DB83EF216476C0678" continuedAt="TextSelection-BB94EE879DB15AC3A960F909AE2DA3B3-1" escape="true">SIGNIFICANT ACCOUNTING POLICIES</ix:nonNumeric></span></div><ix:continuation id="TextSelection-BB94EE879DB15AC3A960F909AE2DA3B3-1"><div style="line-height:120%;padding-bottom:10px;padding-top:8px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company's significant accounting policies are described in Note 2, "Significant Accounting Policies," in the Company's Annual Report on Form 10-K for the year ended </span><span style="font-family:inherit;font-size:10pt;">December&#160;31, 2019</span><span style="font-family:inherit;font-size:10pt;">.

Revenue is primarily generated by short-term projects, most of which are governed by master service agreements that are long-term in nature. These master service agreements are typically entered into with the Company's larger customers and outline the pricing and legal frameworks for such arrangements. Services are provided based on purchase orders or agreements with the customer and include prices based upon units of volume of waste and transportation and other fees.

environment (triggering events) would more likely than not reduce the fair value of a reporting unit below its carrying value. During the period ended March 31, 2020, the Company considered the effects of COVID-19 and evolving changes in demand and pricing for oil, but concluded that there were no triggering events requiring an impairment assessment. This conclusion was based on a qualitative analysis incorporating (i) the significant excess fair value that previously existed in each reporting unit and (ii) assessing the current and long-term performance of the Company given the expectation that these negative effects on the operations and cash flows of each reporting unit arising from COVID-19 related disruptions will be short lived.</span></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company will continue to evaluate the impact of macroeconomic conditions including, but not limited to, the impact of the COVID-19 pandemic on the Company, customers and the greater economy as well as the impact on trends of oil demand.

material.</span></div><ix:nonNumeric contextRef="FD2020Q1YTD" name="us-gaap:ScheduleOfIndefiniteLivedIntangibleAssetsTableTextBlock"

Actions filed against the Company arise from commercial and employment-related claims including alleged class actions related to sales practices and wage and hour claims. The plaintiffs in these actions may be seeking damages or injunctive relief or both. These actions are in various jurisdictions and stages of proceedings, and some are covered in part by insurance. In addition, the Company&#8217;s waste management services operations are regulated by federal, state, provincial and local laws enacted to regulate discharge of materials into the environment, remediation of contaminated soil and groundwater or otherwise protect the environment. This ongoing regulation results in the Company frequently becoming a party to legal or administrative proceedings involving all levels of governmental authorities and other interested parties. The issues involved in such proceedings generally relate to alleged violations of existing permits and licenses or alleged responsibility under federal or state Superfund laws to remediate contamination at properties owned either by the Company or by other parties (&#8220;third-party sites&#8221;) to which either the Company or the prior owners of certain of the Company&#8217;s facilities shipped waste.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">At </span><span style="font-family:inherit;font-size:10pt;">March&#160;31, 2020</span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;">December&#160;31, 2019</span><span style="font-family:inherit;font-size:10pt;">, the Company had recorded reserves of </span><span style="font-family:inherit;font-size:10pt;"><span>$<ix:nonFraction id="d27137788e483-wk-Fact-E02B5C85714A5FA29B07E42907C4CFFA" name="us-gaap:LossContingencyAccrualAtCarryingValue" contextRef="FI2020Q1" unitRef="usd" decimals="-5" scale="6" format="ixt:numdotdecimal">23.6</ix:nonFraction> million</span></span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;"><span>$<ix:nonFraction id="d27137788e487-wk-Fact-7CAE6BA62679587EB7AA262BADBA9F93" name="us-gaap:LossContingencyAccrualAtCarryingValue" contextRef="FI2019Q4" unitRef="usd" decimals="-5" scale="6" format="ixt:numdotdecimal">26.0</ix:nonFraction> million</span></span><span style="font-family:inherit;font-size:10pt;">, respectively, in the Company's financial statements for actual or probable liabilities related to the legal and administrative proceedings in which the Company was then involved, the principal of which are described below.

In September 2007, the U.S. Environmental Protection Agency ("EPA") issued a special notice letter to the Company related to the Devil's Swamp Lake Site ("Devil's Swamp") in East Baton Rouge Parish, Louisiana. Devil's Swamp includes a lake located downstream of an outfall ditch where wastewater and storm water have been discharged, and Devil's Swamp is proposed to be included on the National Priorities List due to the presence of Contaminants of Concern ("COC") cited by the EPA. These COCs include substances of the kind found in wastewater and storm water discharged from the BR Facility in past operations. The EPA originally requested COC generators to submit a good faith offer to conduct a remedial investigation feasibility study directed towards the eventual remediation of the site. In 2018, the Company completed performing corrective actions at the BR Facility under an order issued by the Louisiana Department of Environmental Quality and has also completed conducting the remedial investigation and feasibility study for Devil's Swamp under an order issued </span></div></ix:continuation><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"> 16</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:10pt;"><a style="font-family:inherit;font-size:10pt;" href="#s01A54965C893572790BA11F75C86945B"><span style="font-family:inherit;font-size:10pt;">Table of Contents</span></a></div></div><div><br/></div><ix:continuation id="TextSelection-C6386B5B6B68576DABFA60EC40933114-3"><div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">by the EPA.

We believe we operate, in the aggregate, the largest number of hazardous waste incinerators, landfills and treatment, storage and disposal facilities ("TSDFs") in North America. We serve a diverse customer base, including Fortune 500 companies, across the chemical, energy, manufacturing and additional markets, as well as numerous government agencies. These customers rely on us to deliver a broad range of services including but not limited to end-to-end hazardous waste management, emergency response, industrial cleaning and maintenance and recycling services. We are also the largest re-refiner and recycler of used oil in North America and the largest provider of parts cleaning and related environmental services to commercial, industrial and automotive customers in North America.</span></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Performance of our segments is evaluated on several factors of which the primary financial measure is Adjusted EBITDA as described more fully below. The following is a discussion of how management evaluates its segments in regards to other factors including key performance indicators that management uses to assess the segments&#8217; results, as well as certain macroeconomic trends and influences that impact each reportable segment:</span></div><table cellpadding="0" cellspacing="0" style="padding-bottom:10px;font-family:Times New Roman; font-size:10pt;"><tr><td style="width:72px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:10pt;padding-left:48px;"><span style="font-family:inherit;font-size:10pt;">&#8226;</span></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-weight:bold;">Environmental Services - </span><span style="font-family:inherit;font-size:10pt;">Environmental Services segment results are predicated upon the demand by our customers for waste services directly attributable to waste volumes generated by them and project work for which waste handling and/or disposal is required. In managing the business and evaluating performance, management tracks the volumes and mix of waste handled and disposed of through our owned incinerators and landfills, as well as utilization of such incinerators, labor and billable hours and equipment among other key metrics. Levels of activity and ultimate performance associated with this segment can be impacted by several factors including overall U.S. GDP and U.S. industrial production, weather conditions, efficiency of our operations, technology, changing regulations, competition, market pricing of our services and the management of our related operating costs. Environmental Services results are also impacted by the demand for planned and unplanned industrial related cleaning and maintenance services at customer sites, environmental cleanup services on a scheduled or emergency basis, including response to national events such as major chemical spills, natural disasters, or other events where immediate and specialized services are required. As a result of the recent outbreak of COVID-19, the business has also seen increased demand for response services relative to contagion decontamination.</span></div></td></tr></table><table cellpadding="0" cellspacing="0" style="padding-bottom:10px;font-family:Times New Roman; font-size:10pt;"><tr><td style="width:72px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:10pt;padding-left:48px;"><span style="font-family:inherit;font-size:10pt;">&#8226;</span></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-weight:bold;">Safety-Kleen - </span><span style="font-family:inherit;font-size:10pt;">Safety-Kleen segment results are impacted by an array of core service and product offerings that serve to attract small quantity waste producers customers and integrate them into the Clean Harbors waste network. Core service offerings include parts washer services, containerized waste services, vacuum services, used motor oil collection and contract blending and packaging services. Key performance indicators tracked by the Company relative to these services include the number of parts washer services performed and pricing and volume of used motor oil and waste collected. Results from these services are primarily driven by the overall number of parts washers placed at customer sites and volumes of waste collected, as well as the demand for and frequency of other offered services. These factors can be impacted by overall economic conditions in the marketplace, especially in the automotive related area. In addition to its core service offerings, Safety-Kleen offers high quality recycled base and blended oil products to end </span></div></td></tr></table><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"> 19</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:10pt;"><a style="font-family:inherit;font-size:10pt;" href="#s01A54965C893572790BA11F75C86945B"><span style="font-family:inherit;font-size:10pt;">Table of Contents</span></a></div></div><div><br/></div><div style="line-height:120%;padding-left:72px;padding-bottom:10px;text-align:left;"><span style="font-family:inherit;font-size:10pt;">users including fleet customers, distributors and manufacturers of oil products. Other product offerings include automotive related fluids and shop supplies. Relative to its oil related products, management tracks the Company's volumes and relative percentages of base and blended oil sales along with various pricing metrics associated with the commodity driven marketplace. The segment&#8217;s results are significantly impacted by overall market pricing and product mix associated with base and blended oil products and, more specifically, the market prices of Group II base oils. Costs incurred in connection with the collection of used oil and other raw materials associated with the segment&#8217;s oil related products can also be volatile.

As part of our commitment to ensuring the health and safety of our employees, particularly those performing COVID-19 decontamination services for our customers, thus far we have been able to successfully supply our employees with appropriate personal protective equipment ("PPE") for use in servicing our customers and implemented protocols to actively monitor and report employee illness. To support the safety of all of our employees and operations, precautionary measures have been implemented including suspending non-essential travel, limiting the number of employees attending meetings, reducing the number of people at our locations at any one time, monitoring the health of all employees, arranging administrative employees to work from home and encouraging any employee to work from home where possible.</span></div><div style="line-height:120%;padding-bottom:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company's financial results for the quarter ended March 31, 2020 were not significantly impacted by the COVID-19 pandemic. In the latter half of March 2020, we began to experience a slowdown or closure at some customer sites, particularly in the Safety-Kleen business while also seeing an increase in demand from several customers for decontamination related services in response to COVID-19. However, the outbreak of COVID-19 has resulted in, and is likely to continue to result in, significant economic disruption. In an effort to contain COVID-19, governments have enacted various measures, including orders to close non-essential businesses and personal and commercial travel restrictions. The essential nature of the Company&#8217;s operations has not directly required the closure of any of our facilities. However, in order to respond to the impact on the Safety-Kleen business and in particular the reduced availability of used motor oils which are utilized as feedstock in our re-refining processes, in April 2020, the Company temporarily shuttered nearly half of the production capacity of our oil re-refineries.</span></div><div style="line-height:120%;padding-bottom:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company expects to continue to experience the impacts of COVID-19 throughout the remainder of 2020. In our Environmental Services segment, continued shutdowns of customers' operations could decrease the level of our services that are required and the quantities of commercial and industrial waste disposed of throughout our network of facilities. Lower demand for oil and overall price declines in the global oil market, resulting from COVID-19 impacts, could impact the level of environmental services we provide to our customers in that market. We have seen an increase in emergency response work for COVID-19 related decontamination services which we expect to continue, however these additional services are not expected to fully offset the negative impact of COVID-19 on our Environmental Services segment.</span></div><div style="line-height:120%;padding-bottom:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">We expect that the services provided by our Safety-Kleen segment, especially in the near term, could be more significantly impacted by continued customer shutdowns and therefore less demand for Safety-Kleen services and products. We have observed declining demand in the primary sectors impacting this business including the overall automotive sector, as consumer activity decelerates across the United States and Canada. Lower oil related demand and price declines in the global oil market, exacerbated by COVID-19 impacts, are also expected to reduce revenues and cash flows generated by the business in 2020. Further, the Company has experienced, and likely will continue to face, a shortage of used motor oil supply primarily due to travel restrictions and the presumed temporary closure of certain customer sites. </span></div><div style="line-height:120%;padding-bottom:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The extent to which the&#160;COVID-19&#160;pandemic may impact the Company&#8217;s business, operating results, financial condition or liquidity will depend on future developments, including the duration of the outbreak, travel restrictions, business and workforce disruptions and the effectiveness of actions taken to contain the outbreak and treat its impact. For this reason, the Company expects 2020 profitability to be less than prior expectations, however the Company cannot now reasonably estimate with any degree of certainty the future impact that COVID-19 may have on the Company's results of operations, financial position or liquidity.</span></div><div style="line-height:120%;padding-bottom:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company considered the impact of COVID-19 on the assumptions and estimates used in the preparation of the financial statements and did not identify any significant changes in estimates. Specifically, management concluded that there had not been any triggering events requiring further assessment of asset impairments. Management also assessed the extent to which the current </span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"> 20</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;font-size:10pt;"><a style="font-family:inherit;font-size:10pt;" href="#s01A54965C893572790BA11F75C86945B"><span style="font-family:inherit;font-size:10pt;">Table of Contents</span></a></div></div><div><br/></div><div style="line-height:120%;padding-bottom:10px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">macroeconomic events brought about by COVID-19 and significant declines in oil demand impacted the valuation of expected credit losses on accounts receivable and certain inventory items or resulted in modifications to any significant contracts.

style="font-family:inherit;font-size:10pt;"> driven primarily by a greater volume of higher value waste streams at our incinerators and higher service-related revenues. Increased utilization and average pricing at our incinerator facilities contributed $23.7 million to the direct revenue growth in the Environmental Services segment. Utilization at our incinerator facilities was 86% in the first quarter of 2020, a significant increase from the first quarter of 2019, directly resulting from fewer down days in the period. In the first quarter of 2019, utilization was unfavorably impacted by additional down days due to a fire at a neighboring facility. Average price per ton at our incinerators during the first quarter of 2020 increased approximately 11% from the first quarter of 2019.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">Emergency response services contributed an incremental $21.2 million to the direct revenue growth of the Environmental Services segment from the comparable period, half of which was related to emergency response services associated with the COVID-19 pandemic, with the remaining increase from other project-based services.

style="font-family:inherit;font-size:10pt;">. Increased volumes and pricing in the base oil market accounted for $15.1 million of incremental base oil revenues from the comparable period in 2019. Direct revenue from sales of blended oil products increased $4.2 million, driven both by higher volume and better pricing. The increase in volumes of base and blended oil was largely the result of favorable weather conditions in 2020 as compared to the first quarter of 2019 when adverse weather conditions delayed the delivery of our products. Revenues generated through our core service offerings such as handling of containerized waste and vacuum services increased $3.6 million from the same period in 2019, and revenues from contract blending and packaging also increased $2.5 million. These increases were partially offset by a $4.7 million reduction in direct revenue driven by lower volume of recycled fuel oil and refinery byproducts sales. In the first three months of 2020, parts washer services were relatively consistent with the same quarter in the prior year. The impact of foreign currency translation on our Canadian operations was minimal.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Cost of Revenues</span><span style="font-family:inherit;font-size:10pt;">&#160;</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">We believe that our ability to manage operating costs is important to our ability to remain price competitive.

style="font-family:inherit;font-size:10pt;">We use Adjusted EBITDA to enhance our understanding of our operating performance, which represents our views concerning our performance in the ordinary,

We regularly communicate Adjusted EBITDA results to our lenders since our loan covenants are based upon levels of Adjusted EBITDA achieved and to our board of directors and we discuss with the board our interpretation of such results. We also compare our Adjusted EBITDA performance against internal targets as a key factor in determining cash and stock bonus compensation for executives and other employees, largely because we believe that this measure is indicative of how the fundamental business is performing and is being managed.</span></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">We also provide information relating to our Adjusted EBITDA so that analysts, investors and other interested persons have the same data that we use to assess our core operating performance. We believe that Adjusted EBITDA should be viewed only as a supplement to the GAAP financial information. We also believe, however, that providing this information in addition to, and together with, GAAP financial information permits the users of our financial statements to obtain a better understanding of our core operating performance and to evaluate the efficacy of the methodology and information used by management to evaluate and measure such performance on a standalone and a comparative

Additionally, adjusted free cash flow is a metric on which a portion of management incentive compensation is based. We define adjusted free cash flow as net cash from operating activities, less additions to property, plant and equipment plus proceeds from sales or disposals of fixed assets. We exclude cash impacts of items derived from non-operating activities such as taxes paid in connection with divestitures and in the current period have also excluded cash paid in connection with the purchase of our corporate headquarters and certain capital improvements to the site as these expenditures are considered one-time in nature. Adjusted free cash flow should not be considered an alternative to net cash from operating activities or other measurements under GAAP. Adjusted free cash flow is not calculated identically by all companies, and therefore our measurements of adjusted free cash flow may not be comparable to similarly titled measures reported by other companies. </span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"> 27</span></div></div><hr

Long-lived assets with finite lives are reviewed for impairment whenever events or changes in circumstances (triggering events) indicate that their carrying value may not be entirely recoverable. When such factors and circumstances exist, management compares the projected undiscounted future cash flows associated with the related asset or group of assets to the respective carrying amounts. The impairment loss, if any, would be measured as the excess of the carrying amount over the fair value of the asset and is recorded in the period in which the determination is made. </span></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">During the period ended March 31, 2020, we considered the expected adverse impact of COVID-19 and the overall sharp decline in oil pricing, partially driven by the global response to COVID-19 and partially driven by increased production from certain oil producing countries, and concluded that a triggering event had not occurred.

style="font-family:inherit;font-size:10pt;"> of our common stock. We have funded and intend to fund the repurchases through available cash resources. The stock repurchase program authorizes us to purchase our common stock on the open market or in privately negotiated transactions periodically in a manner that complies with applicable U.S. securities laws. The number of shares purchased and the timing of the purchases has depended and will depend on several factors, including share price, cash required for business plans, trading volume and other conditions. During April 2018, we implemented a repurchase plan in accordance with Rule 10b5-1 promulgated under the Securities Exchange Act of 1934, as amended. Future repurchases will be made under the Rule 10b5-1 plan as well as open market or privately negotiated transactions as described above. We have no obligation to repurchase stock under this program and may suspend or terminate the repurchase program at any time.</span></div></td></tr></table><div><br/></div><div

On </span><span style="font-family:inherit;font-size:10pt;">March&#160;31, 2020</span><span style="font-family:inherit;font-size:10pt;">, the Company drew down </span><span style="font-family:inherit;font-size:10pt;"><span>$150.0 million</span></span><span style="font-family:inherit;font-size:10pt;"> on the revolving credit facility out of an abundance of caution given the macroeconomic uncertainties surrounding the COVID-19 global pandemic. As of </span><span style="font-family:inherit;font-size:10pt;">March&#160;31, 2020</span><span style="font-family:inherit;font-size:10pt;">, the Company had </span><span style="font-family:inherit;font-size:10pt;"><span>$80.7 million</span></span><span style="font-family:inherit;font-size:10pt;"> available to borrow under the revolving credit facility and outstanding letters of credit were </span><span style="font-family:inherit;font-size:10pt;"><span>$141.2 million</span></span><span style="font-family:inherit;font-size:10pt;">.

Although the interest rate on the Term Loans is variable, the Company has effectively fixed the interest rate on </span><span style="font-family:inherit;font-size:10pt;"><span>$350.0 million</span></span><span style="font-family:inherit;font-size:10pt;"> aggregate principal amount of the Term Loans outstanding by entering into interest rate swap agreements in 2018 with a notional amount of </span><span style="font-family:inherit;font-size:10pt;"><span>$350.0 million</span></span><span style="font-family:inherit;font-size:10pt;">. Under the terms of the interest rate swap agreements, the Company receives interest based on the one-month LIBOR index and pays interest at a weighted average annual interest rate of approximately </span><span style="font-family:inherit;font-size:10pt;"><span>2.92%</span></span><span style="font-family:inherit;font-size:10pt;">, resulting in an effective annual interest rate of approximately </span><span style="font-family:inherit;font-size:10pt;"><span>4.67%</span></span><span style="font-family:inherit;font-size:10pt;">.&#160;</span></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company recognizes derivative instruments as either assets or liabilities on the balance sheet at fair value. No ineffectiveness has been identified on these swaps and, therefore, all unrealized changes in fair value are recorded in accumulated other comprehensive loss. Amounts are reclassified from accumulated other comprehensive loss into interest expense on the statement of operations in the same period or periods during which the hedged transaction affects earnings. </span></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">As of </span><span style="font-family:inherit;font-size:10pt;">March&#160;31, 2020</span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;">December&#160;31, 2019</span><span style="font-family:inherit;font-size:10pt;">, the Company has recorded a derivative liability with a fair value of </span><span style="font-family:inherit;font-size:10pt;"><span>$38.1 million</span></span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;"><span>$20.8 million</span></span><span style="font-family:inherit;font-size:10pt;">, respectively, within accrued expenses in connection with these cash flow hedges.</span></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The fair value of the interest rate swaps is calculated using discounted cash flow valuation methodologies based upon the one-month LIBOR yield curves that are observable at commonly quoted intervals for the full term of the interest rate swaps and as such is considered a Level 2 measure according to the fair value hierarchy.</span></div><span></span>

environment (triggering events) would more likely than not reduce the fair value of a reporting unit below its carrying value. During the period ended March 31, 2020, the Company considered the effects of COVID-19 and evolving changes in demand and pricing for oil, but concluded that there were no triggering events requiring an impairment assessment. This conclusion was based on a qualitative analysis incorporating (i) the significant excess fair value that previously existed in each reporting unit and (ii) assessing the current and long-term performance of the Company given the expectation that these negative effects on the operations and cash flows of each reporting unit arising from COVID-19 related disruptions will be short lived.</span></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company will continue to evaluate the impact of macroeconomic conditions including, but not limited to, the impact of the COVID-19 pandemic on the Company, customers and the greater economy as well as the impact on trends of oil demand.

The Company's Environmental Services operating segment generally has the following three sources of revenue: </span></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Technical Services</span><span style="font-family:inherit;font-size:10pt;">&#8212;Technical Services revenues are generated from fees charged for waste material management and disposal services including onsite environmental management services, collection and transportation, packaging, recycling, treatment and disposal of waste. Revenue is primarily generated by short-term projects, most of which are governed by master service agreements that are long-term in nature. These master service agreements are typically entered into with the Company's larger customers and outline the pricing and legal frameworks for such arrangements. Services are provided based on purchase orders or agreements with the customer and include prices based upon units of volume of waste and transportation and other fees. Collection and transportation revenues are recognized over time, as the customer receives and consumes the benefits of the services as they are being performed and the Company has a right to payment for performance completed to date. The Company uses the input method to recognize revenue over time, based on time and materials incurred. Revenues for treatment and disposal of waste are recognized upon completion of treatment, final disposition in a landfill or incineration, or when the waste is shipped to a third party for processing and disposal. The Company periodically enters into bundled arrangements for </span></div><div style="line-height:120%;padding-bottom:10px;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">the collection and transportation and disposal of waste. For such arrangements, transportation and disposal are considered distinct performance obligations and the Company allocates revenue to each based on the relative standalone selling price (i.e. the estimated price that a customer would pay for the services on a standalone basis). Revenues from waste that is not yet completely processed and disposed and the related costs are deferred. The deferred revenues and costs are recognized when the related services are completed. The period between collection and transportation and the final processing and disposal ranges depending on location of the customer, but generally is measured in days.</span></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Field and Emergency Response Services</span><span style="font-family:inherit;font-size:10pt;">&#8212;Field Services revenues are generated from cleanup services at customer sites, including municipalities and utilities, or other locations on a scheduled or emergency response basis. Services include confined space entry for tank cleaning, site decontamination, large remediation projects, demolition, spill cleanup on land and water, railcar cleaning, product recovery and transfer and vacuum services. Additional services include filtration and water treatment services. Response services for environmental, contamination or pandemic related emergencies include any scale from man-made disasters such as oil spills, to natural disasters such as hurricanes. More recently demand has increased for projects involving contagion decontamination services in response to the COVID-19 pandemic. Field and emergency response services are provided based on purchase orders or agreements with customers and include prices generally based upon daily, hourly or job rates for equipment, materials and personnel. The Company recognizes revenue for these services over time, as the customer receives and consumes the benefits of the service as they are being performed and the Company has a right to payment for performance completed to date. The Company uses the input method to recognize revenue over time, based on time and materials incurred. The duration of such services can be over a number of hours, several days or even months for larger scale projects.</span></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Industrial Services and Other</span><span style="font-family:inherit;font-size:10pt;">&#8212;Industrial Services revenues are primarily generated from industrial and specialty services provided to refineries, mines, upgraders, chemical plants, pulp and paper mills, manufacturing facilities, power generation facilities and other industrial customers throughout North America. Services include in-plant cleaning and maintenance services, plant outage and turnaround services, decoking and pigging, chemical cleaning, high and ultra-high pressure water cleaning, pipeline inspection and coating services, large tank and surface impoundment cleaning, oilfield transport, daylighting, production services and upstream energy services, such as exploration and drilling for industrial oil and gas customers. Services are provided based on purchase orders or agreements with the customer and include prices based upon daily, hourly or job rates for equipment, materials and personnel. The Company recognizes revenue for these services over time, as the customer receives and consumes the benefits of the services as they are being performed and the Company has a right to payment for performance completed to date.

Containerized waste services consist of profiling, collecting, transporting and recycling or disposing of a wide variety of waste. Other products and services include sale of complementary supply products including automotive fluids and shop supplies and other environmental services. Parts washer services include customer use of our parts washer equipment, cleaning and maintenance of the parts washer equipment and removal and replacement of used cleaning fluids. Parts washer services are considered a single performance obligation due to the highly integrated and interdependent nature of the arrangement. Revenue from parts washer services is recognized over the service interval as the customer receives the benefit of the services. Collection and transportation revenues are recognized over time, as the customer receives and consumes the benefits of the services as they are being performed and the Company has a right to payment for performance completed to date. The Company uses the input method to recognize revenue over time, based on time and materials incurred. Product revenue is recognized upon the transfer of control whereby control transfers when the products are delivered to the customer.</span></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Safety-Kleen Oil</span><span style="font-family:inherit;font-size:10pt;">&#8212;Revenues from Safety-Kleen Oil are generated from sales of high-quality base and blended lubricating oils to third-party distributors, government agencies, fleets, railroads and industrial customers. The business also sells recycled fuel oil to asphalt plants, industrial plants and pulp and paper companies. The used oil is also processed into vacuum gas oil which can be further re-refined into lubricant base oils or sold directly into the marine diesel oil fuel market. Revenue for oil products is recognized at a point in time, upon the transfer of control. Control transfers when the products are delivered to the customer.</span></div><div style="line-height:120%;padding-bottom:8px;text-align:left;font-size:10pt;"><span

Actions filed against the Company arise from commercial and employment-related claims including alleged class actions related to sales practices and wage and hour claims. The plaintiffs in these actions may be seeking damages or injunctive relief or both. These actions are in various jurisdictions and stages of proceedings, and some are covered in part by insurance. In addition, the Company&#8217;s waste management services operations are regulated by federal, state, provincial and local laws enacted to regulate discharge of materials into the environment, remediation of contaminated soil and groundwater or otherwise protect the environment. This ongoing regulation results in the Company frequently becoming a party to legal or administrative proceedings involving all levels of governmental authorities and other interested parties. The issues involved in such proceedings generally relate to alleged violations of existing permits and licenses or alleged responsibility under federal or state Superfund laws to remediate contamination at properties owned either by the Company or by other parties (&#8220;third-party sites&#8221;) to which either the Company or the prior owners of certain of the Company&#8217;s facilities shipped waste.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">At </span><span style="font-family:inherit;font-size:10pt;">March&#160;31, 2020</span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;">December&#160;31, 2019</span><span style="font-family:inherit;font-size:10pt;">, the Company had recorded reserves of </span><span style="font-family:inherit;font-size:10pt;"><span>$23.6 million</span></span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;"><span>$26.0 million</span></span><span style="font-family:inherit;font-size:10pt;">, respectively, in the Company's financial statements for actual or probable liabilities related to the legal and administrative proceedings in which the Company was then involved, the principal of which are described below. In management's opinion, it is not reasonably possible that the potential liability beyond what has been recorded, if any, that may result from these actions, either individually or collectively, will have a material effect on our financial position, results of operations or cash flows. The Company periodically adjusts the aggregate amount of these reserves when actual or probable liabilities are paid or otherwise discharged, new claims arise or additional relevant information about existing or probable claims becomes available. As of </span><span style="font-family:inherit;font-size:10pt;">March&#160;31, 2020</span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;">December&#160;31, 2019</span><span style="font-family:inherit;font-size:10pt;">, the </span><span style="font-family:inherit;font-size:10pt;"><span>$23.6 million</span></span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;"><span>$26.0 million</span></span><span style="font-family:inherit;font-size:10pt;">, respectively, of reserves consisted of (i)&#160;</span><span style="font-family:inherit;font-size:10pt;"><span>$17.2 million</span></span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;"><span>$18.4 million</span></span><span style="font-family:inherit;font-size:10pt;">, respectively, related to pending legal or administrative proceedings, including Superfund liabilities, which were included in remedial liabilities on the consolidated balance sheets, and (ii)&#160;</span><span style="font-family:inherit;font-size:10pt;"><span>$6.4 million</span></span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;"><span>$7.6 million</span></span><span style="font-family:inherit;font-size:10pt;">, respectively, primarily related to federal, state and provincial enforcement actions, which were included in accrued expenses on the consolidated balance sheets.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">As of </span><span style="font-family:inherit;font-size:10pt;">March&#160;31, 2020</span><span style="font-family:inherit;font-size:10pt;">, the principal legal and administrative proceedings in which the Company was involved, or which had been terminated during </span><span style="font-family:inherit;font-size:10pt;">2020</span><span style="font-family:inherit;font-size:10pt;">, were as follows:</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Ville Mercier. </span><span style="font-family:inherit;font-size:10pt;">In September 2002, the Company acquired the stock of a subsidiary (the "Mercier Subsidiary") which owns a hazardous waste incinerator in Ville Mercier, Quebec (the "Mercier Facility"). The property adjacent to the Mercier Facility, which is also owned by the Mercier Subsidiary, is now contaminated as a result of actions dating back to 1968, when the Government of Quebec issued </span><span style="font-family:inherit;font-size:10pt;"><span>two</span></span><span style="font-family:inherit;font-size:10pt;"> permits to dump organic liquids into lagoons on the property to a company unrelated to the Mercier Subsidiary. In 1999, Ville Mercier and </span><span style="font-family:inherit;font-size:10pt;"><span>three</span></span><span style="font-family:inherit;font-size:10pt;"> neighboring municipalities filed separate legal proceedings against the Mercier Subsidiary and the Government of Quebec. In 2012, the municipalities amended their existing statement of claim to seek </span><span style="font-family:inherit;font-size:10pt;"><span>$2.9 million</span></span><span style="font-family:inherit;font-size:10pt;"> (CAD) in general damages and </span><span style="font-family:inherit;font-size:10pt;"><span>$10.0 million</span></span><span style="font-family:inherit;font-size:10pt;"> (CAD) in punitive damages, plus interest and costs, as well as injunctive relief. Both the Government of Quebec and the Company have filed summary judgment motions against the municipalities. The parties are attempting to negotiate a resolution and hearings on the motions have been delayed. In September&#160;2007, the Quebec Minister of Sustainable Development, Environment and Parks issued a notice pursuant to Section&#160;115.1 of the Environment Quality Act, superseding notices issued in 1992, which are the subject of the pending litigation. The more recent notice notifies the Mercier Subsidiary that, if the Mercier Subsidiary does not take certain remedial measures at the site, the Minister intends to undertake those measures at the site and claim direct and </span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">indirect costs related to such measures. The Company has accrued for costs expected to be incurred relative to the resolution of this matter and believes this matter will not have future material effect on its financial position, results of operations or cash flows.</span></div><div style="line-height:120%;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Safety-Kleen Legal Proceedings. </span><span style="font-family:inherit;font-size:10pt;">On December 28, 2012, the Company acquired Safety-Kleen, Inc. ("Safety-Kleen") and thereby became subject to the legal proceedings in which Safety-Kleen was a party on that date. In addition to certain Superfund proceedings in which Safety-Kleen has been named as a potentially responsible party as described below under &#8220;Superfund Proceedings,&#8221; the principal such legal proceedings involving Safety-Kleen which were outstanding as of </span><span style="font-family:inherit;font-size:10pt;">March&#160;31, 2020</span><span style="font-family:inherit;font-size:10pt;"> were as follows:</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Product Liability Cases.</span><span style="font-family:inherit;font-size:10pt;"> Safety-Kleen has been named as a defendant in various lawsuits that are currently pending in various courts and jurisdictions throughout the United States, including approximately </span><span style="font-family:inherit;font-size:10pt;"><span>60</span></span><span style="font-family:inherit;font-size:10pt;"> proceedings (excluding cases which have been settled but not formally dismissed) as of </span><span style="font-family:inherit;font-size:10pt;">March&#160;31, 2020</span><span style="font-family:inherit;font-size:10pt;">, wherein persons claim personal injury resulting from the use of Safety-Kleen's parts cleaning equipment or cleaning products. These proceedings typically involve allegations that the solvent used in Safety-Kleen's parts cleaning equipment contains contaminants and/or that Safety-Kleen's recycling process does not effectively remove the contaminants that become entrained in the solvent during their use. In addition, certain claimants assert that Safety-Kleen failed to adequately warn the product user of potential risks, including a historic failure to warn that solvent contains trace amounts of toxic or hazardous substances such as benzene. </span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company maintains insurance that it believes will provide coverage for these product liability claims (over amounts accrued for self-insured retentions and deductibles in certain limited cases), except for punitive damages to the extent not insurable under state law or excluded from insurance coverage. The Company also believes that these claims lack merit and has historically vigorously defended, and intends to continue to vigorously defend, itself and the safety of its products against all these claims. Such matters are subject to many uncertainties and outcomes are not predictable with assurance. Consequently, the Company is unable to ascertain the ultimate aggregate amount of monetary liability or financial impact with respect to these matters as of </span><span style="font-family:inherit;font-size:10pt;">March&#160;31, 2020</span><span style="font-family:inherit;font-size:10pt;">. From </span><span style="font-family:inherit;font-size:10pt;">January 1, 2020</span><span style="font-family:inherit;font-size:10pt;"> to </span><span style="font-family:inherit;font-size:10pt;">March&#160;31, 2020</span><span style="font-family:inherit;font-size:10pt;">, </span><span style="font-family:inherit;font-size:10pt;"><span>three</span></span><span style="font-family:inherit;font-size:10pt;"> product liability claims were settled or dismissed. Due to the nature of these claims and the related insurance, the Company did not incur any expense as insurance provided coverage in full for all such claims. Safety-Kleen may be named in similar, additional lawsuits in the future, including claims for which insurance coverage may not be available.&#160;&#160;&#160;&#160;</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Superfund Proceedings</span></div><div style="line-height:120%;padding-bottom:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">The Company has been notified that either the Company (which, since December 28, 2012, includes Safety-Kleen) or the prior owners of certain of the Company's facilities for which the Company may have certain indemnification obligations have been identified as potentially responsible parties ("PRPs") or potential PRPs in connection with </span><span style="font-family:inherit;font-size:10pt;"><span>130</span></span><span style="font-family:inherit;font-size:10pt;"> sites which are subject to or are proposed to become subject to proceedings under federal or state Superfund laws. Of the </span><span style="font-family:inherit;font-size:10pt;"><span>130</span></span><span style="font-family:inherit;font-size:10pt;"> sites, </span><span style="font-family:inherit;font-size:10pt;"><span>five</span></span><span style="font-family:inherit;font-size:10pt;"> (including the BR Facility described below) involve facilities that are now owned or leased by the Company and </span><span style="font-family:inherit;font-size:10pt;"><span>125</span></span><span style="font-family:inherit;font-size:10pt;"> involve third-party sites to which either the Company or the prior owners of certain of the Company&#8217;s facilities shipped wastes.

The amount of such actual and potential liability is inherently difficult to estimate because of, among other relevant factors, uncertainties as to the legal liability, if any, of the Company or the prior owners of certain of the Company's facilities to contribute a portion of the cleanup costs, the assumptions that must be made in calculating the estimated cost and timing of remediation, the identification of other PRPs and their respective capability and obligation to contribute to remediation efforts and the existence and legal standing of indemnification agreements, if any, with prior owners, which may either benefit the Company or subject the Company to potential indemnification obligations. The Company believes its potential liability could exceed </span><span style="font-family:inherit;font-size:10pt;"><span>$100,000</span></span><span style="font-family:inherit;font-size:10pt;"> at </span><span style="font-family:inherit;font-size:10pt;"><span>10</span></span><span style="font-family:inherit;font-size:10pt;"> of the </span><span style="font-family:inherit;font-size:10pt;"><span>125</span></span><span style="font-family:inherit;font-size:10pt;"> third-party sites.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">BR Facility. </span><span style="font-family:inherit;font-size:10pt;">The Company acquired in 2002 a former hazardous waste incinerator and landfill in Baton Rouge (the "BR Facility"), for which operations had been previously discontinued by the prior owner. In September 2007, the U.S. Environmental Protection Agency ("EPA") issued a special notice letter to the Company related to the Devil's Swamp Lake Site ("Devil's Swamp") in East Baton Rouge Parish, Louisiana. Devil's Swamp includes a lake located downstream of an outfall ditch where wastewater and storm water have been discharged, and Devil's Swamp is proposed to be included on the National Priorities List due to the presence of Contaminants of Concern ("COC") cited by the EPA. These COCs include substances of the kind found in wastewater and storm water discharged from the BR Facility in past operations. The EPA originally requested COC generators to submit a good faith offer to conduct a remedial investigation feasibility study directed towards the eventual remediation of the site. In 2018, the Company completed performing corrective actions at the BR Facility under an order issued by the Louisiana Department of Environmental Quality and has also completed conducting the remedial investigation and feasibility study for Devil's Swamp under an order issued </span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">by the EPA. The Company cannot presently estimate the potential additional liability for the Devil's Swamp cleanup until a final remedy is selected by the EPA with issuance of a Record of Decision.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Third-Party Sites. </span><span style="font-family:inherit;font-size:10pt;">Of the </span><span style="font-family:inherit;font-size:10pt;"><span>125</span></span><span style="font-family:inherit;font-size:10pt;"> third-party sites at which the Company has been notified it is a PRP or potential PRP or may have indemnification obligations, Clean Harbors has an indemnification agreement at </span><span style="font-family:inherit;font-size:10pt;"><span>11</span></span><span style="font-family:inherit;font-size:10pt;"> of these sites with ChemWaste, a former subsidiary of Waste Management,&#160;Inc., and at </span><span style="font-family:inherit;font-size:10pt;"><span>six</span></span><span style="font-family:inherit;font-size:10pt;"> additional of these third-party sites, Safety-Kleen has a similar indemnification agreement with McKesson Corporation. These agreements indemnify the Company (which now includes Safety-Kleen) with respect to any liability at the </span><span style="font-family:inherit;font-size:10pt;"><span>17</span></span><span style="font-family:inherit;font-size:10pt;"> sites for waste disposed prior to the Company's (or Safety-Kleen's) acquisition of the former subsidiaries of Waste Management and McKesson which had shipped wastes to those sites. Accordingly, Waste Management or McKesson are paying all costs of defending those subsidiaries in those </span><span style="font-family:inherit;font-size:10pt;"><span>17</span></span><span style="font-family:inherit;font-size:10pt;"> cases, including legal fees and settlement costs. However, there can be no guarantee that the Company's ultimate liabilities for those sites will not exceed the amount recorded or that indemnities applicable to any of these sites will be available to pay all or a portion of related costs. Except for the indemnification agreements which the Company holds from ChemWaste, McKesson and two other entities, the Company does not have an indemnity agreement with respect to any of the </span><span style="font-family:inherit;font-size:10pt;"><span>125</span></span><span style="font-family:inherit;font-size:10pt;"> third-party sites discussed above.</span></div><div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Federal, State and Provincial Enforcement Actions</span></div><div style="line-height:120%;padding-bottom:10px;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">From time to time, the Company pays fines or penalties in regulatory proceedings relating primarily to waste treatment, storage or disposal facilities. As of </span><span style="font-family:inherit;font-size:10pt;">March&#160;31, 2020</span><span style="font-family:inherit;font-size:10pt;"> and </span><span style="font-family:inherit;font-size:10pt;">December&#160;31, 2019</span><span style="font-family:inherit;font-size:10pt;">, there were </span><span style="font-family:inherit;font-size:10pt;"><span>12</span></span><span style="font-family:inherit;font-size:10pt;"> proceedings for which the Company reasonably believes that the sanctions could equal or exceed </span><span style="font-family:inherit;font-size:10pt;"><span>$100,000</span></span><span style="font-family:inherit;font-size:10pt;">. The Company believes that the fines or other penalties in these or any of the other regulatory proceedings will, individually or in the aggregate, not have a material effect on its financial condition, results of operations or cash flows.</span></div><span></span>

As a result of the outbreak, many companies have experienced disruptions in their operations, workforce and markets served, including a significant reduction in the demand for petroleum-based products. The Company's businesses and operations began being adversely impacted by effects of COVID-19 in March of 2020 when circumstances surrounding and responses to the pandemic, including stay-at-home orders, began to materialize in North America. These disruptions are expected to have a significant adverse impact on the Company's operating results during the second quarter of 2020 and the remainder of the year. The full extent of the COVID-19 outbreak and changes in demand for oil and the impact on the Company&#x2019;s operations is uncertain. A prolonged disruption could have a material adverse impact on financial results and business operations of the Company.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:46px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;In addition and in response to the COVID-19 outbreak, the Company has seen increased demand in emergency response services. Specifically the Company is addressing the safety of its customers and communities by providing contagion decontamination services. In conducting these services, employee safety is paramount and the Company has been able to provide appropriate personal protective equipment and support to those performing these services.&lt;/span&gt;&lt;/div&gt;</us-gaap:OrganizationConsolidationAndPresentationOfFinancialStatementsDisclosureTextBlock>

Revenue is primarily generated by short-term projects, most of which are governed by master service agreements that are long-term in nature. These master service agreements are typically entered into with the Company's larger customers and outline the pricing and legal frameworks for such arrangements. Services are provided based on purchase orders or agreements with the customer and include prices based upon units of volume of waste and transportation and other fees. Collection and transportation revenues are recognized over time, as the customer receives and consumes the benefits of the services as they are being performed and the Company has a right to payment for performance completed to date. The Company uses the input method to recognize revenue over time, based on time and materials incurred. Revenues for treatment and disposal of waste are recognized upon completion of treatment, final disposition in a landfill or incineration, or when the waste is shipped to a third party for processing and disposal. The Company periodically enters into bundled arrangements for &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;text-align:left;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;the collection and transportation and disposal of waste. For such arrangements, transportation and disposal are considered distinct performance obligations and the Company allocates revenue to each based on the relative standalone selling price (i.e. the estimated price that a customer would pay for the services on a standalone basis). Revenues from waste that is not yet completely processed and disposed and the related costs are deferred. The deferred revenues and costs are recognized when the related services are completed. The period between collection and transportation and the final processing and disposal ranges depending on location of the customer, but generally is measured in days.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;Field and Emergency Response Services&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&#x2014;Field Services revenues are generated from cleanup services at customer sites, including municipalities and utilities, or other locations on a scheduled or emergency response basis. Services include confined space entry for tank cleaning, site decontamination, large remediation projects, demolition, spill cleanup on land and water, railcar cleaning, product recovery and transfer and vacuum services. Additional services include filtration and water treatment services. Response services for environmental, contamination or pandemic related emergencies include any scale from man-made disasters such as oil spills, to natural disasters such as hurricanes. More recently demand has increased for projects involving contagion decontamination services in response to the COVID-19 pandemic. Field and emergency response services are provided based on purchase orders or agreements with customers and include prices generally based upon daily, hourly or job rates for equipment, materials and personnel.

Containerized waste services consist of profiling, collecting, transporting and recycling or disposing of a wide variety of waste. Other products and services include sale of complementary supply products including automotive fluids and shop supplies and other environmental services. Parts washer services include customer use of our parts washer equipment, cleaning and maintenance of the parts washer equipment and removal and replacement of used cleaning fluids. Parts washer services are considered a single performance obligation due to the highly integrated and interdependent nature of the arrangement. Revenue from parts washer services is recognized over the service interval as the customer receives the benefit of the services. Collection and transportation revenues are recognized over time, as the customer receives and consumes the benefits of the services as they are being performed and the Company has a right to payment for performance completed to date. The Company uses the input method to recognize revenue over time, based on time and materials incurred. Product revenue is recognized upon the transfer of control whereby control transfers when the products are delivered to the customer.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;Safety-Kleen Oil&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&#x2014;Revenues from Safety-Kleen Oil are generated from sales of high-quality base and blended lubricating oils to third-party distributors, government agencies, fleets, railroads and industrial customers. The business also sells recycled fuel oil to asphalt plants, industrial plants and pulp and paper companies. The used oil is also processed into vacuum gas oil which can be further re-refined into lubricant base oils or sold directly into the marine diesel oil fuel market. Revenue for oil products is recognized at a point in time, upon the transfer of control. Control transfers when the products are delivered to the customer.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:8px;text-align:left;font-size:10pt;"&gt;&lt;span

Revenue is primarily generated by short-term projects, most of which are governed by master service agreements that are long-term in nature. These master service agreements are typically entered into with the Company's larger customers and outline the pricing and legal frameworks for such arrangements. Services are provided based on purchase orders or agreements with the customer and include prices based upon units of volume of waste and transportation and other fees. Collection and transportation revenues are recognized over time, as the customer receives and consumes the benefits of the services as they are being performed and the Company has a right to payment for performance completed to date. The Company uses the input method to recognize revenue over time, based on time and materials incurred. Revenues for treatment and disposal of waste are recognized upon completion of treatment, final disposition in a landfill or incineration, or when the waste is shipped to a third party for processing and disposal. The Company periodically enters into bundled arrangements for &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;text-align:left;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;the collection and transportation and disposal of waste. For such arrangements, transportation and disposal are considered distinct performance obligations and the Company allocates revenue to each based on the relative standalone selling price (i.e. the estimated price that a customer would pay for the services on a standalone basis). Revenues from waste that is not yet completely processed and disposed and the related costs are deferred. The deferred revenues and costs are recognized when the related services are completed. The period between collection and transportation and the final processing and disposal ranges depending on location of the customer, but generally is measured in days.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;Field and Emergency Response Services&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&#x2014;Field Services revenues are generated from cleanup services at customer sites, including municipalities and utilities, or other locations on a scheduled or emergency response basis. Services include confined space entry for tank cleaning, site decontamination, large remediation projects, demolition, spill cleanup on land and water, railcar cleaning, product recovery and transfer and vacuum services. Additional services include filtration and water treatment services. Response services for environmental, contamination or pandemic related emergencies include any scale from man-made disasters such as oil spills, to natural disasters such as hurricanes. More recently demand has increased for projects involving contagion decontamination services in response to the COVID-19 pandemic. Field and emergency response services are provided based on purchase orders or agreements with customers and include prices generally based upon daily, hourly or job rates for equipment, materials and personnel. The Company recognizes revenue for these services over time, as the customer receives and consumes the benefits of the service as they are being performed and the Company has a right to payment for performance completed to date.

Containerized waste services consist of profiling, collecting, transporting and recycling or disposing of a wide variety of waste. Other products and services include sale of complementary supply products including automotive fluids and shop supplies and other environmental services. Parts washer services include customer use of our parts washer equipment, cleaning and maintenance of the parts washer equipment and removal and replacement of used cleaning fluids. Parts washer services are considered a single performance obligation due to the highly integrated and interdependent nature of the arrangement. Revenue from parts washer services is recognized over the service interval as the customer receives the benefit of the services. Collection and transportation revenues are recognized over time, as the customer receives and consumes the benefits of the services as they are being performed and the Company has a right to payment for performance completed to date.

Product revenue is recognized upon the transfer of control whereby control transfers when the products are delivered to the customer.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;Safety-Kleen Oil&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&#x2014;Revenues from Safety-Kleen Oil are generated from sales of high-quality base and blended lubricating oils to third-party distributors, government agencies, fleets, railroads and industrial customers. The business also sells recycled fuel oil to asphalt plants, industrial plants and pulp and paper companies. The used oil is also processed into vacuum gas oil which can be further re-refined into lubricant base oils or sold directly into the marine diesel oil fuel market. Revenue for oil products is recognized at a point in time, upon the transfer of control. Control transfers when the products are delivered to the customer.&lt;/span&gt;&lt;/div&gt;</us-gaap:RevenueFromContractWithCustomerPolicyTextBlock>

style="font-family:inherit;font-size:10pt;"&gt;The Company assesses goodwill for impairment on an annual basis as of December&#160;31 or at an interim date when events or changes in the business environment (triggering events) would more likely than not reduce the fair value of a reporting unit below its carrying value. During the period ended March 31, 2020, the Company considered the effects of COVID-19 and evolving changes in demand and pricing for oil, but concluded that there were no triggering events requiring an impairment assessment. This conclusion was based on a qualitative analysis incorporating (i) the significant excess fair value that previously existed in each reporting unit and (ii) assessing the current and long-term performance of the Company given the expectation that these negative effects on the operations and cash flows of each reporting unit arising from COVID-19 related disruptions will be short lived.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;The Company will continue to evaluate the impact of macroeconomic conditions including, but not limited to, the impact of the COVID-19 pandemic on the Company, customers and the greater economy as well as the impact on trends of oil demand. If these macroeconomic conditions are protracted or result in significant changes in demand for our products and services, a goodwill impairment might be identified and the amount might be material.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-align:left;padding-left:0px;text-indent:48px;font-size:10pt;"&gt;&lt;span

As of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;March&#160;31, 2020&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;, the Company had &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$80.7 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; available to borrow under the revolving credit facility and outstanding letters of credit were &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$141.2 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;.

Although the interest rate on the Term Loans is variable, the Company has effectively fixed the interest rate on &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$350.0 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; aggregate principal amount of the Term Loans outstanding by entering into interest rate swap agreements in 2018 with a notional amount of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$350.0 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;. Under the terms of the interest rate swap agreements, the Company receives interest based on the one-month LIBOR index and pays interest at a weighted average annual interest rate of approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;2.92%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;, resulting in an effective annual interest rate of approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;4.67%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;.&#160;&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;The Company recognizes derivative instruments as either assets or liabilities on the balance sheet at fair value. No ineffectiveness has been identified on these swaps and, therefore, all unrealized changes in fair value are recorded in accumulated other comprehensive loss. Amounts are reclassified from accumulated other comprehensive loss into interest expense on the statement of operations in the same period or periods during which the hedged transaction affects earnings. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;As of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;March&#160;31, 2020&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;December&#160;31, 2019&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;, the Company has recorded a derivative liability with a fair value of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$38.1 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$20.8 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;, respectively, within accrued expenses in connection with these cash flow hedges.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;The fair value of the interest rate swaps is calculated using discounted cash flow valuation methodologies based upon the one-month LIBOR yield curves that are observable at commonly quoted intervals for the full term of the interest rate swaps and as such is considered a Level 2 measure according to the fair value hierarchy.&lt;/span&gt;&lt;/div&gt;</us-gaap:DebtDisclosureTextBlock>

Actions filed against the Company arise from commercial and employment-related claims including alleged class actions related to sales practices and wage and hour claims. The plaintiffs in these actions may be seeking damages or injunctive relief or both. These actions are in various jurisdictions and stages of proceedings, and some are covered in part by insurance. In addition, the Company&#x2019;s waste management services operations are regulated by federal, state, provincial and local laws enacted to regulate discharge of materials into the environment, remediation of contaminated soil and groundwater or otherwise protect the environment. This ongoing regulation results in the Company frequently becoming a party to legal or administrative proceedings involving all levels of governmental authorities and other interested parties. The issues involved in such proceedings generally relate to alleged violations of existing permits and licenses or alleged responsibility under federal or state Superfund laws to remediate contamination at properties owned either by the Company or by other parties (&#x201c;third-party sites&#x201d;) to which either the Company or the prior owners of certain of the Company&#x2019;s facilities shipped waste.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;At &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;March&#160;31, 2020&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;December&#160;31, 2019&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;, the Company had recorded reserves of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$23.6 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$26.0 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;, respectively, in the Company's financial statements for actual or probable liabilities related to the legal and administrative proceedings in which the Company was then involved, the principal of which are described below. In management's opinion, it is not reasonably possible that the potential liability beyond what has been recorded, if any, that may result from these actions, either individually or collectively, will have a material effect on our financial position, results of operations or cash flows. The Company periodically adjusts the aggregate amount of these reserves when actual or probable liabilities are paid or otherwise discharged, new claims arise or additional relevant information about existing or probable claims becomes available. As of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;March&#160;31, 2020&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;December&#160;31, 2019&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;, the &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$23.6 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$26.0 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;, respectively, of reserves consisted of (i)&#160;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$17.2 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$18.4 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;, respectively, related to pending legal or administrative proceedings, including Superfund liabilities, which were included in remedial liabilities on the consolidated balance sheets, and (ii)&#160;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$6.4 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$7.6 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;, respectively, primarily related to federal, state and provincial enforcement actions, which were included in accrued expenses on the consolidated balance sheets.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;As of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;March&#160;31, 2020&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;, the principal legal and administrative proceedings in which the Company was involved, or which had been terminated during &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;2020&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;, were as follows:&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;Ville Mercier. &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;In September 2002, the Company acquired the stock of a subsidiary (the "Mercier Subsidiary") which owns a hazardous waste incinerator in Ville Mercier, Quebec (the "Mercier Facility"). The property adjacent to the Mercier Facility, which is also owned by the Mercier Subsidiary, is now contaminated as a result of actions dating back to 1968, when the Government of Quebec issued &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;two&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; permits to dump organic liquids into lagoons on the property to a company unrelated to the Mercier Subsidiary. In 1999, Ville Mercier and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;three&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; neighboring municipalities filed separate legal proceedings against the Mercier Subsidiary and the Government of Quebec. In 2012, the municipalities amended their existing statement of claim to seek &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$2.9 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; (CAD) in general damages and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$10.0 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; (CAD) in punitive damages, plus interest and costs, as well as injunctive relief. Both the Government of Quebec and the Company have filed summary judgment motions against the municipalities. The parties are attempting to negotiate a resolution and hearings on the motions have been delayed. In September&#160;2007, the Quebec Minister of Sustainable Development, Environment and Parks issued a notice pursuant to Section&#160;115.1 of the Environment Quality Act, superseding notices issued in 1992, which are the subject of the pending litigation. The more recent notice notifies the Mercier Subsidiary that, if the Mercier Subsidiary does not take certain remedial measures at the site, the Minister intends to undertake those measures at the site and claim direct and &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;indirect costs related to such measures. The Company has accrued for costs expected to be incurred relative to the resolution of this matter and believes this matter will not have future material effect on its financial position, results of operations or cash flows.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;Safety-Kleen Legal Proceedings. &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;On December 28, 2012, the Company acquired Safety-Kleen, Inc. ("Safety-Kleen") and thereby became subject to the legal proceedings in which Safety-Kleen was a party on that date. In addition to certain Superfund proceedings in which Safety-Kleen has been named as a potentially responsible party as described below under &#x201c;Superfund Proceedings,&#x201d; the principal such legal proceedings involving Safety-Kleen which were outstanding as of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;March&#160;31, 2020&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; were as follows:&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;Product Liability Cases.&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; Safety-Kleen has been named as a defendant in various lawsuits that are currently pending in various courts and jurisdictions throughout the United States, including approximately &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;60&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; proceedings (excluding cases which have been settled but not formally dismissed) as of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;March&#160;31, 2020&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;, wherein persons claim personal injury resulting from the use of Safety-Kleen's parts cleaning equipment or cleaning products. These proceedings typically involve allegations that the solvent used in Safety-Kleen's parts cleaning equipment contains contaminants and/or that Safety-Kleen's recycling process does not effectively remove the contaminants that become entrained in the solvent during their use. In addition, certain claimants assert that Safety-Kleen failed to adequately warn the product user of potential risks, including a historic failure to warn that solvent contains trace amounts of toxic or hazardous substances such as benzene. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;The Company maintains insurance that it believes will provide coverage for these product liability claims (over amounts accrued for self-insured retentions and deductibles in certain limited cases), except for punitive damages to the extent not insurable under state law or excluded from insurance coverage. The Company also believes that these claims lack merit and has historically vigorously defended, and intends to continue to vigorously defend, itself and the safety of its products against all these claims. Such matters are subject to many uncertainties and outcomes are not predictable with assurance. Consequently, the Company is unable to ascertain the ultimate aggregate amount of monetary liability or financial impact with respect to these matters as of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;March&#160;31, 2020&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;. From &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;January 1, 2020&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; to &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;March&#160;31, 2020&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;, &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;three&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; product liability claims were settled or dismissed. Due to the nature of these claims and the related insurance, the Company did not incur any expense as insurance provided coverage in full for all such claims.

The amount of such actual and potential liability is inherently difficult to estimate because of, among other relevant factors, uncertainties as to the legal liability, if any, of the Company or the prior owners of certain of the Company's facilities to contribute a portion of the cleanup costs, the assumptions that must be made in calculating the estimated cost and timing of remediation, the identification of other PRPs and their respective capability and obligation to contribute to remediation efforts and the existence and legal standing of indemnification agreements, if any, with prior owners, which may either benefit the Company or subject the Company to potential indemnification obligations. The Company believes its potential liability could exceed &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$100,000&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; at &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;10&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; of the &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;125&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; third-party sites.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;BR Facility. &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;The Company acquired in 2002 a former hazardous waste incinerator and landfill in Baton Rouge (the "BR Facility"), for which operations had been previously discontinued by the prior owner. In September 2007, the U.S. Environmental Protection Agency ("EPA") issued a special notice letter to the Company related to the Devil's Swamp Lake Site ("Devil's Swamp") in East Baton Rouge Parish, Louisiana. Devil's Swamp includes a lake located downstream of an outfall ditch where wastewater and storm water have been discharged, and Devil's Swamp is proposed to be included on the National Priorities List due to the presence of Contaminants of Concern ("COC") cited by the EPA. These COCs include substances of the kind found in wastewater and storm water discharged from the BR Facility in past operations. The EPA originally requested COC generators to submit a good faith offer to conduct a remedial investigation feasibility study directed towards the eventual remediation of the site. In 2018, the Company completed performing corrective actions at the BR Facility under an order issued by the Louisiana Department of Environmental Quality and has also completed conducting the remedial investigation and feasibility study for Devil's Swamp under an order issued &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;by the EPA. The Company cannot presently estimate the potential additional liability for the Devil's Swamp cleanup until a final remedy is selected by the EPA with issuance of a Record of Decision.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;padding-top:10px;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;font-style:italic;"&gt;Third-Party Sites. &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;Of the &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;125&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; third-party sites at which the Company has been notified it is a PRP or potential PRP or may have indemnification obligations, Clean Harbors has an indemnification agreement at &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;11&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; of these sites with ChemWaste, a former subsidiary of Waste Management,&#160;Inc., and at &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;six&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; additional of these third-party sites, Safety-Kleen has a similar indemnification agreement with McKesson Corporation. These agreements indemnify the Company (which now includes Safety-Kleen) with respect to any liability at the &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;17&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; sites for waste disposed prior to the Company's (or Safety-Kleen's) acquisition of the former subsidiaries of Waste Management and McKesson which had shipped wastes to those sites. Accordingly, Waste Management or McKesson are paying all costs of defending those subsidiaries in those &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;17&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; cases, including legal fees and settlement costs. However, there can be no guarantee that the Company's ultimate liabilities for those sites will not exceed the amount recorded or that indemnities applicable to any of these sites will be available to pay all or a portion of related costs. Except for the indemnification agreements which the Company holds from ChemWaste, McKesson and two other entities, the Company does not have an indemnity agreement with respect to any of the &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;125&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; third-party sites discussed above.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;padding-top:10px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;"&gt;Federal, State and Provincial Enforcement Actions&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:10px;text-indent:48px;font-size:10pt;"&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;From time to time, the Company pays fines or penalties in regulatory proceedings relating primarily to waste treatment, storage or disposal facilities. As of &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;March&#160;31, 2020&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;December&#160;31, 2019&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;, there were &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;12&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt; proceedings for which the Company reasonably believes that the sanctions could equal or exceed &lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;&lt;span&gt;$100,000&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:inherit;font-size:10pt;"&gt;. The Company believes that the fines or other penalties in these or any of the other regulatory proceedings will, individually or in the aggregate, not have a material effect on its financial condition, results of operations or cash flows.&lt;/span&gt;&lt;/div&gt;</us-gaap:CommitmentsAndContingenciesDisclosureTextBlock>

<td class="text">The Company's Environmental Services operating segment generally has the following three sources of revenue: <div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Technical Services</span><span style="font-family:inherit;font-size:10pt;">&#8212;Technical Services revenues are generated from fees charged for waste material management and disposal services including onsite environmental management services, collection and transportation, packaging, recycling, treatment and disposal of waste. Revenue is primarily generated by short-term projects, most of which are governed by master service agreements that are long-term in nature. These master service agreements are typically entered into with the Company's larger customers and outline the pricing and legal frameworks for such arrangements. Services are provided based on purchase orders or agreements with the customer and include prices based upon units of volume of waste and transportation and other fees. Collection and transportation revenues are recognized over time, as the customer receives and consumes the benefits of the services as they are being performed and the Company has a right to payment for performance completed to date. The Company uses the input method to recognize revenue over time, based on time and materials incurred. Revenues for treatment and disposal of waste are recognized upon completion of treatment, final disposition in a landfill or incineration, or when the waste is shipped to a third party for processing and disposal. The Company periodically enters into bundled arrangements for </span></div><div style="line-height:120%;padding-bottom:10px;text-align:left;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">the collection and transportation and disposal of waste. For such arrangements, transportation and disposal are considered distinct performance obligations and the Company allocates revenue to each based on the relative standalone selling price (i.e. the estimated price that a customer would pay for the services on a standalone basis). Revenues from waste that is not yet completely processed and disposed and the related costs are deferred. The deferred revenues and costs are recognized when the related services are completed. The period between collection and transportation and the final processing and disposal ranges depending on location of the customer, but generally is measured in days.</span></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Field and Emergency Response Services</span><span style="font-family:inherit;font-size:10pt;">&#8212;Field Services revenues are generated from cleanup services at customer sites, including municipalities and utilities, or other locations on a scheduled or emergency response basis. Services include confined space entry for tank cleaning, site decontamination, large remediation projects, demolition, spill cleanup on land and water, railcar cleaning, product recovery and transfer and vacuum services. Additional services include filtration and water treatment services. Response services for environmental, contamination or pandemic related emergencies include any scale from man-made disasters such as oil spills, to natural disasters such as hurricanes. More recently demand has increased for projects involving contagion decontamination services in response to the COVID-19 pandemic. Field and emergency response services are provided based on purchase orders or agreements with customers and include prices generally based upon daily, hourly or job rates for equipment, materials and personnel. The Company recognizes revenue for these services over time, as the customer receives and consumes the benefits of the service as they are being performed and the Company has a right to payment for performance completed to date. The Company uses the input method to recognize revenue over time, based on time and materials incurred. The duration of such services can be over a number of hours, several days or even months for larger scale projects.</span></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Industrial Services and Other</span><span style="font-family:inherit;font-size:10pt;">&#8212;Industrial Services revenues are primarily generated from industrial and specialty services provided to refineries, mines, upgraders, chemical plants, pulp and paper mills, manufacturing facilities, power generation facilities and other industrial customers throughout North America. Services include in-plant cleaning and maintenance services, plant outage and turnaround services, decoking and pigging, chemical cleaning, high and ultra-high pressure water cleaning, pipeline inspection and coating services, large tank and surface impoundment cleaning, oilfield transport, daylighting, production services and upstream energy services, such as exploration and drilling for industrial oil and gas customers. Services are provided based on purchase orders or agreements with the customer and include prices based upon daily, hourly or job rates for equipment, materials and personnel. The Company recognizes revenue for these services over time, as the customer receives and consumes the benefits of the services as they are being performed and the Company has a right to payment for performance completed to date.

Containerized waste services consist of profiling, collecting, transporting and recycling or disposing of a wide variety of waste. Other products and services include sale of complementary supply products including automotive fluids and shop supplies and other environmental services. Parts washer services include customer use of our parts washer equipment, cleaning and maintenance of the parts washer equipment and removal and replacement of used cleaning fluids. Parts washer services are considered a single performance obligation due to the highly integrated and interdependent nature of the arrangement. Revenue from parts washer services is recognized over the service interval as the customer receives the benefit of the services. Collection and transportation revenues are recognized over time, as the customer receives and consumes the benefits of the services as they are being performed and the Company has a right to payment for performance completed to date. The Company uses the input method to recognize revenue over time, based on time and materials incurred. Product revenue is recognized upon the transfer of control whereby control transfers when the products are delivered to the customer.</span></div><div style="line-height:120%;padding-bottom:10px;text-align:left;text-indent:48px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;font-style:italic;">Safety-Kleen Oil</span><span style="font-family:inherit;font-size:10pt;">&#8212;Revenues from Safety-Kleen Oil are generated from sales of high-quality base and blended lubricating oils to third-party distributors, government agencies, fleets, railroads and industrial customers. The business also sells recycled fuel oil to asphalt plants, industrial plants and pulp and paper companies. The used oil is also processed into vacuum gas oil which can be further re-refined into lubricant base oils or sold directly into the marine diesel oil fuel market. Revenue for oil products is recognized at a point in time, upon the transfer of control. Control transfers when the products are delivered to the customer.</span></div><span></span>

As a result of the outbreak, many companies have experienced disruptions in their operations, workforce and markets served, including a significant reduction in the demand for petroleum-based products. The Company's businesses and operations began being adversely impacted by effects of COVID-19 in March of 2020 when circumstances surrounding and responses to the pandemic, including stay-at-home orders, began to materialize in North America. These disruptions are expected to have a significant adverse impact on the Company's operating results during the second quarter of 2020 and the remainder of the year. The full extent of the COVID-19 outbreak and changes in demand for oil and the impact on the Company&#8217;s operations is uncertain. A prolonged disruption could have a material adverse impact on financial results and business operations of the Company.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:46px;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In addition and in response to the COVID-19 outbreak, the Company has seen increased demand in emergency response services. Specifically the Company is addressing the safety of its customers and communities by providing contagion decontamination services. In conducting these services, employee safety is paramount and the Company has been able to provide appropriate personal protective equipment and support to those performing these services.</span></div><span></span>
