Let me turn the call over to our CEO, Alan McKim. Alan? Thanks, Michael. Good morning, everyone, thank you for joining us. Starting on Slide three, before discussing our year-end results, I want to reflect for a moment on the fact that this will be my final earnings call as CEO, and I'll be passing the torch to Eric and Mike at the end of this month. As I mentioned on our Q3 call, it's been my privilege to lead this tremendous organization, and I've enjoyed communicating and engaging with our shareholders over the years, maybe some quarters a little bit more than others. The company has been on a remarkable growth trajectory for the past five-plus years, and I'm confident that you'll see more of these exceptional results under Eric and Mike's leadership, along with the rest of the executive team that now includes Eric Dugas as our Chief Financial Officer and Brian Weber as our President of our Safety-Kleen Sustainability Solutions segment, which we announced in a separate news release this morning. Eric Dugas is an outstanding Chief Accounting Officer and has become a strong business partner to the operational teams. He'll be a terrific CFO for us. Brian is a 30-year employee who has held many key roles at the company. Most recently, he has led our M&A efforts and managing many corporate functions, but he also oversaw our Base Products and Services business, BPS, within SKSS. BPS includes a variety of services such as our sale and distribution of blended products through our OilPlus closed loop program. Based on his background and broad expertise, Brian is the ideal choice to lead SKSS through on its next stage of growth and build on the company's strong position as the most sustainable offering in the lubricants market. Having said all that about the team, I'm still gonna be here come April working on overall strategy, M&A, and driving technology enhancements that support our future growth, productivity, and lowering cost. Turning to our results, I'll let Mike take you through the details, but overall I'd say that we experienced the most of the same positive trends in Q4 that we saw all year, particularly in our environmental services segment. That enabled us to conclude a record 2022 with continued strong performance. The quarter also continued to demonstrate the considerable leverage in our business model as 14% top-line growth drove a 29% increase in Q4 adjusted EBITDA. Our most impressive result, however, for both the quarter and the year was in our safety results, where we delivered the best year in our history. As a management team, we work hard to try to make sure that all our colleagues return home to their families every day uninjured. Our goal for 2022 was to achieve a total recordable incident rate below one. This year, the team achieved an amazing TRIR of 0.73. I'm so thankful to the entire organization for all their hard work achieving that rate, and we're gonna continue to challenge them in 2023 to be even better. In addition to our fantastic safety results, we hit $1 billion of adjusted annual EBITDA for the first time in our history in 2022, while improving in our ROIC for the fifth consecutive year. Revenue for the year was up 36% and adjusted EBITDA increased 51% with a record margin of 19.8%. We achieved some other notable accomplishments this past year, including combining HPC with our legacy U.S. industrial service business, advancing the construction of our new incinerator in Nebraska, acquiring our A3 refinery facility, launching our KLEEN+ brand in our base oil market, reducing our voluntary turnover while significantly increasing hiring of our billable headcount, and finally, releasing our groundbreaking PFAS incineration study. Turning to our environmental service segment on Slide four. The 15% growth in revenue was driven by a combination of volume and pricing. We continue to see considerable demand for our network of disposal and recycling assets. In Q4, we benefited from manufacturing and chemical industry tailwinds as reshoring, regulatory enforcement, and projects generated healthy volumes for our facilities. Incineration utilization was 84% in the quarter, reflecting multi-day unplanned outages at both Deer Park and El Dorado due to the extreme weather that we had during December. Nevertheless, the mix of higher value waste streams in Q4 resulted in a 21% increase in average incineration pricing. Q4 landfill volumes rose by 28% as we continue to win multiple waste project opportunities. Our industrial service business performed well in Q4 as we continue to harmonize our U.S. operations now working under the HPC Industrial brand. Safety-Kleen environmental revenue was up more than 20% as core offerings have now surpassed pre-pandemic levels. Field services revenue grew 8% due to pricing and branch growth initiatives. Looking at environmental service segment profitability, adjusted EBITDA growth again outpaced our top line, increasing by 35%. We worked hard to make sure that our pricing kept up with inflation, but while also implementing a myriad of cost reduction and productivity initiatives. We leveraged our SG&A costs while substantially growing this segment. Collectively, this fueled a 340 basis point increase in our environmental services margins from a year ago. Moving to Slide five. Profitability in our SKSS segment cooled down after a record-breaking Q3. Revenue in the segment was up 9% in the quarter on higher pricing and revenues from the acquisition that we completed in June, as well as some higher sales of recycled fuel oil because of the plant disruptions that took place in December, which was based on the extreme weather impacts that we had. Our adjusted EBITDA and margins declined based on our revenue mix as we sold less volumes of base oil and lubricants. We made the strategic decision in the quarter to build up some base and blended inventory for a seasonally stronger period in the first half of this year when we expect demand and margins to be more attractive. Our Q4 profitability was affected by severe weather at multiple refineries that impacted production levels and also resulted in higher costs. On the waste oil collection side, however, volumes were strong again, up slightly from a year ago. Given market conditions, our sales of blended products and our direct volumes at 8% of total output was essentially in line with our expectations. The additive shortages that plagued the lubricant industry through much of 2022 started to abate in Q4. This improvement should be a tailwind for overall base oil demand in 2023, while also enabling us to increase our blended volumes this year. We also made investments in the direct lube oil sales force to drive growth with our OilPlus program. Turning to Slide six in our capital allocation strategy. On the M&A front, we are continuing to see a good flow of potential bolt-on transactions for both our operating segments. In late December, we purchased a small waste oil collection business in West Texas, and more recently, we signed a purchase and sale agreement to acquire Thompson Industrial Services in an all-cash deal for approximately $100 million. We expect that deal to close at the end of this month. This transaction, which will add approximately $120 million in annual revenue, will expand our industrial service presence in the Southeast U.S. It'll broaden our capabilities and bring us into verticals where we have sold environmental services, but not industrial services, verticals like paper, mining, and power. With the acquisition of HPC, we have built a scalable platform to add complementary industrial services companies like Thompson that are synergistic and enhance our cross-selling of environmental services. Mike Battles will take you through some of our recent debt activities, but the key takeaway is that we will continue to maintain a strong balance sheet that will enable us to remain opportunistic on the M&A front. With that, let me turn things over to Eric Gerstenberg. Eric? Thanks, Alan. We are continuing to evaluate opportunities to drive organic growth through internal investments. Along those lines, our new state-of-the-art incinerator in Kimball, Nebraska remains on plan and on budget. While we could certainly put it to work today, we're excited to have that come to market with 70,000 tons of much-needed capacity in early 2025. We enter 2023 with healthy momentum across all our key environmental services businesses. Our primary markets remain in great shape given the underlying market dynamics and essential nature of our business. Within the environmental services segment, our backlog of waste remains at record levels, particularly due to the December outages, which well positions us for 2023. Given the diversity of our customer base, we expect healthy demand for our network of disposal and recycling assets to continue all year based on our customer interactions. Our service businesses all experienced solid growth in 2022. With the expansion of our billable headcount throughout the year, we should benefit from those new hires here in 2023. We expect our base business to continue to grow due to the ongoing reshoring trend among manufacturers and investments in areas like semiconductors, pharma, and EV batteries. We also expect project opportunities to continue to be healthy this year as monies from the infrastructure bill and other programs are released into the market, as well as regulators providing more clarity around PFAS. Based on the results of our comprehensive third-party PFAS study, where we released late last year, we believe our incinerators not only represent the most appropriate solution for PFAS compounds, but the only commercially scalable destruction solution already available in the market. With SKSS, we continue to carefully manage both ends of our re-refining spread and collect the waste oil volumes needed to support our plants. Despite base oil demand taking a step down in Q4 from the heightened Q3 levels, today we are beginning to experience a normal seasonal pickup, and we are confident overall market conditions will remain favorable this year. While 2022 presents a challenge as a difficult comp for us, we see numerous opportunities to enhance our profitability in this segment, including raising production from 2022 levels, including a full year of contribution from our synergy plan, increasing sales of blended products, and capitalizing on the increasing interest in our sustainable products. Additionally, our KLEEN+ base oil brand that we launched in mid-2022 is helping to facilitate discussions with customers seeking solutions that will lower the environmental impact of their automotive and industrial lubricant products. With that, let me turn it over to Mike Battles. Thank you, Eric, and good morning, everyone. Turning to our income statement on Slide eight, Q4 revenue increased 14% to $1.28 billion, with nearly all of it coming from organic growth. For the year, we grew 36% to nearly $5.2 billion, with a majority coming from organic growth and a full year of contributions from HPC, which we acquired in October 2021. Q4 adjusted EBITDA was 29% higher than a year ago, coming in at $224.2 million, which equates to a margin of 17.5% or a 190 basis points increase from Q4 of last year. We achieved this result through gross margin improvements, fixed cost leverage, and controlling SG&A spending. For the year, adjusted EBITDA climbed 51%, with margins up 200 basis points to 19.8%. If you look at our 2022 results by segment, you'll see that all three of our reporting segments meaningfully contributed to the overall margin expansion. This is an outstanding accomplishment given the inflationary environment we operated in all year long. Q4 gross margins improved 110 basis points to 30.3%. This is the first quarter where we had HPC in both periods, and our gross profit improvement reflects our ability to price to offset inflation, increase margins through productivity improvements, and deliver strong operational efficiency gains. Q4 SG&A expense as a percentage of revenue improved 100 basis points to 13.2%. On our Q4 2021 earnings call a year ago, we shared the large opportunity to realize synergies as we integrated HPC. Our results reflect those captured efficiencies. On top of that, we continue to leverage our global capability center in India and diligently monitor all our costs. For the full year, SG&A costs as a percentage of revenue was 12.1%, reflecting a reduction of 200 basis points in line with our November guidance. As we look ahead to 2023, we expect SG&A costs as a percentage of revenue to remain in this 12% range. Depreciation and amortization in Q4 increased, as expected, to $87 million, largely reflecting acquisitions. For the full year, depreciation and amortization rose to $347.6 million, just above the range we provided in November. For 2023, we anticipate depreciation and amortization in the range of $345 million-$355 million. Income from operations in Q4 increased 55% to $127.4 million, driven by healthy revenue growth combined with our margin improvement in environmental services. For the full year, our income from ops climbed to an impressive 82% to $634.7 million. Net income in the quarter was $82.5 million, up 68% from a year ago. For the full year, both net income and GAAP EPS more than doubled to $411.7 million and $7.56 per share. Turning to our balance sheet highlights on Slide six. Cash and short-term marketable securities at year-end was $555 million, up more than $40 million from September 30. We ended the year with debt of just over $2.4 billion. We took several prudent steps related to our debt in Q4 and subsequent to year-end. First, during Q4, we strategically paid down our variable rate debt by $100 million in response to the rising interest rate environment. Second, in January, we refinanced the remaining $640 million of our term loan B loan due in 2024. We achieved this by issuing $500 million of new eight-year unsecured senior notes due 2031, and by tapping our ABL revolver for $114 million. Leveraging our lower rate revolver not only decreases our interest expense, but also lowered the cost of refinancing and provides flexibility to more easily reduce our debt further going forward should we elect to do so. Leverage on a net debt to EBITDA basis at year-end was approximately 1.9 times after being north of 3x to start the year. Our weighted average cost of debt today, following the refinancing in January, is approximately 5%, with almost 80% of our debt at fixed rates. Turning to cash flows on Slide ten. Cash from operations in Q4 was a robust $268.7 million. CapEx net of disposals was $96.8 million, up from the prior year, primarily reflecting the ongoing construction of our Nebraska incinerator. In Q4, we spent roughly $18 million on the Kimball project, which brings our full year spend to $45 million. For 2022, we delivered adjusted Free Cash Flow of $289.9 million at the top end of the range we provided in November. For 2023, we expect our net CapEx to be in the range of $400 million-$420 million. The majority of the increase from the $336 million we reported in 2022 relates to our investment in Kimball, which we expect to double to approximately $90 million in 2023. We're also continuing to invest in our transportation fleet and equipment to accommodate the growth of our business, eliminating third-party rental spend whenever possible. During Q4, we bought back just over 52,000 shares of stock at a total cost of $6 million. Year to date, we've repurchased 537,000 shares at a total cost of $50.2 million for an average cost of $93.51 a share. We have approximately $105 million remaining under our existing buyback program. Moving to Slide 11. Based on our 2022 results and current market conditions for both our operating segments, we expect 2023 adjusted EBITDA in the range of $1.01 billion-$1.05 billion, with a midpoint of $1.03 billion. Looking at our guidance from a quarterly perspective, we expect Q1 adjusted EBITDA to be approximately 20% higher than Q1 of 2022. Now I'll provide the breakout of how our full year 2023 adjusted EBITDA guidance translates to our business segments. In Environmental Services, we expect adjusted EBITDA at the midpoint of our guidance to increase 6%-7% from full year 2022. Demand for our disposal facilities continues to enable us to maintain our pricing strategies, drive higher volumes, and funnel more favorable mix into our network. Service demand remains healthy. I should note that our guidance does not include the Thompson Industrial transaction at this time. For SKSS, we anticipate full year 2023 adjusted EBITDA at the midpoint of our guidance to decrease by approximately 15% from 2022, reflecting recent base oil pricing trends. Despite the recent decline in base oil pricing, we have a number of meaningful offsets that Eric outlined in his remarks. In our corporate segment, at the midpoint of our guide, we now expect negative adjusted EBITDA to be up low single digits from 2022. The year-over-year change is due to wage inflation and rising insurance expense, partially offset by cost-saving initiatives and lower bonus compensation compared with 2022, where we had record results across the board. Based on our 2022 Free Cash Flow results, rising interest rates, and latest working capital assumptions, we expect 2023 adjusted Free Cash Flow in the range of $305 million-$345 million or $325 million at the midpoint. I want to remind everyone that this range includes the $90 million we are spending on the new incinerator this year. If you add that back, the midpoint of our guidance range would be about $415 million. In summary, Q4 was a great finish to a record year. As Alan highlighted, we again saw lots of the same favorable trends in the quarter that we experienced throughout the year. There is substantial demand in our network with a very healthy backlog. volumes within our network of facilities are further supported by encouraging levels of interest across our service businesses. Based on our demand level we are seeing as we kick off the year, we are projecting to continue the positive growth trajectory in 2023, led by our Environmental Services segment, where we maintain a bullish outlook. We expect another strong year for Clean Harbors in 2023. Not only are we bullish about our prospects for 2023, but we believe our long-term outlook is positive and plan to share our perspective on that at our Investor Day, which will take place on March 29th in Chicago with the larger executive team. The event will conclude with a tour of our re-refinery just across the border in Indiana. I encourage any institutional investors or analysts interested in attending to reach out to Jim. With that, Christine, please open up the call for questions. Thank you. We will now be conducting a question-and-answer session. If you would like to ask a question, please press star one on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press Star two if you would like to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. One moment please while we poll for questions. Thank you. Our first question comes from the line of Michael Hoffman with Stifel. Please proceed with your question. Hey, good morning. Alan, I was sitting here counting on my fingers and toes. I think you've done 140 earnings calls, and I believe I've been on all of them, and I wish you the best of luck. Thank you, Michael. Some of those were good calls and some were not as good, right? Yeah, they were, it was always interesting. I'll say this out loud because I think people ought to acknowledge it. You always could see where the puck was going. I always respected that about you. Thank you. Mike Battles, price, and I think about the lines of business at environmental. Are we getting price in all three pieces, the technical services side, industrial field services, and SKE? When you think about that, how much of it's rollover from last year versus rollover plus you've discovered price as a component of growth? Yeah, Michael, I think that Certainly as we look at Q1, a lot of its rollover price we did in the back half of the years 'cause as you remember, Q1 we started to put price increases in place in Q4 and Q1, but most of them weren't in place until the back half of Q1. I think that the year-on-year kind of price increases will certainly impact Q1. Make no mistake, I think that we also continue down the path of looking at ways to increase price in all, you know, three or four of the, let's say, the environmental services businesses, whether it be tech service on disposal, field services, industrial, and the SKE branch business. I think there's plenty of good opportunities there. You talk about kinda learning how to do it more effectively. I think that's true. I think that pricing will be part of our story, has been part of our story for many years and will continue. I think that there's certainly opportunities there to continue to drive price well beyond the rollover that we see here in Q1. A point of clarification around industrial and field services. If I think about what you look like today versus what you looked like in 2016, am I right in that you basically have consolidated the other three major national players, and so the discipline that comes into the market about price should be better, whatever the economic environment looks like? Sure, yeah. This is Alan. Michael, I think, you know, there was certainly some benefits of bringing, you know, some major players together, leveraging the technology and leveraging the relationships that we all had with our, with our key customers. I think one of the things we've been able to do is work with a lot of our accounts to, you know, provide better safety programs, better technology, hands-free technology, bring more R&D now into the, into the business, working with them to develop ways of performing the kind of services on these massive plants to help them get back online faster and safer and at a lower cost. I think the customers really have benefited, I think, from that consolidation that's taken place. Michael, this is Eric. I'll add to that. I think that with our platform that we have today, we're obviously an unparalleled national provider of field services and industrial services. We have, as you know, many national accounts with locations throughout North America that we are able to support with the broad network that we have today. Okay, that helps. The Free Cash Flow, Mike, you had a very strong corporate overhead number, which I'm assuming is above average incentive comp for a great year, well-deserved. That pays out in the spring of 2023. That's a headwind, I'm assuming, into the Free Cash Flow assumption. Is that about $10 million? Is that the right way to think about that? I think it's a little less than that. We, you know, we had a great year in 2021 as well. The, the rollover impact is, you know, 5-10, Michael, I'd say. Okay. There's some things like that working capital is a pretty healthy use in 2022. Is it assumed neutral, or do you assume it's a source in 2023 when I think about the free cash? Yeah, when you look at Free Cash Flow for 2022, certainly working capital, receivables, inventory, other areas was quite a use. You know, we're assuming in the guide that we kinda hold the line on working capital, and I think that's gonna be a positive. Obviously, if we get better at it, and we're putting a lot of programs in place to get better at managing receivables, getting them paid faster. If that gets better, that's a big win to Free Cash Flow. We're assuming that it gets no worse. I think part of the challenge in 2022 was a very large acquisition and the integration around that. That was a bit of a headwind in 2022 from a Free Cash Flow perspective as it relates to working capital. Okay. Then just to be clear, the corporate overhead guide is off the 237, 3%-5% growth off the 237, not normalized? Yes. Yeah, yeah. Okay. We took the actual number and we assume there's gonna be some. You know, the thing when you think of the corporate cost, I think we assume that there's, you know, wage inflation, things like that. There are other, you know, cost saving initiatives that we're putting in place. You know, those aren't in the guide, and we're hopeful we'll do better than that. Okay. Thank you very much. Okay, Michael. Our next question comes from the line of Noah Kaye with Oppenheimer. Please proceed with your question. Thanks for taking the questions, and congratulations to all. Eric, congratulations on the appointment. I guess, Kimball, the $90 million spend increase for 2023, that was always in plan. I just wanna confirm, A, that you're reiterating the budget there. I guess we've seen, just broadly, across a number of industries, some delays in terms of large projects timing and some CapEx inflation. With you reiterating the timeline and the budget, can you just talk through for us what drives your confidence and ability to bring the plant online timely, any line of sight to major equipment deliveries, labor ability, and so forth? Yeah, Noah, this is Eric. I'll respond to that. Yes, so reconfirming the $90 million estimate spend for 2023. The way we look at this project, we obviously have a wealth of experience from how we built out our El Dorado addition, train 2. From that, we've applied it to the much of the same principles to how we're thinking about building out Kimball, how we've been building out Kimball. The components, how we're managing it, the same management team from a construction general contractor that we're using, albeit internally, we're managing that very closely. We meet monthly and go through the project. We do have some longer lead time items, but those continue to be on track as we went through 2022 and into 2023. We're still confident in meeting our start-up date and our start-up timing for that 70,000 tons. Okay, great. Thanks. I just wanna make sure I'm clear on how you're thinking about the SKSS business, here in 1Q and kind of the cadence of the years. You know, the comp is still favorable here in 1Q. Obviously gets tougher as we go later in the year. It sounds like basically you've accumulated some inventory. There were some impacts from weather, but you can take advantage of the seasonal uptick to sell that through. I guess, you know, how long would you expect to take to work that off? Is that a quarter or 2? You know, how you think about the sort of the cadence of performance for the segment over the year. When you think about kind of the... I think that that inventory get works off in the 1st half, you know, March, April, May is kind of a very busy season for the sales of our base and blended products. You know, I think that when I think about the cadence, you know, Q1 will be, you know, flattish, maybe up a little bit from last year. Q2 and Q3, given the record year quarters we had in the SKSS business, they're probably gonna be down, and Q4 will be up, given some of the weather challenges we had in Q4 of 2022. I think the V will be an easier V, if you will, in Q4 of 2023. I think of the cadence of the year, I think Q1 is flattish, Q2, Q3 down, Q4 up. Really helpful. Thank you. All right, Noah. Our next question comes from a line of Quinn Fredrickson with Baird. Please proceed with your question. Hey, good morning, guys. Thanks for taking my question... Hi, Quinn. Hi, Quinn. ... to Eric and Brian. Congrats to Eric and Brian, and best of luck to Alan. Thank you. Mike, I just wanted to start out with, you made some comments in the past about the ES business, kind of starting with industrial production as a base for growth. Can you give us a sense for just what kind of IP environment you might be assuming for the 2023 guidance? Yeah, Quinn. you know, I think that, you know, we've had a couple great years of ES organic growth. In 2022, it was 20% organic growth. In 2021, it was 8% organic growth. You know, industrial production is scheduled to be, you know, low to mid-single digits. I think we can do better than that, but we can't assume that we're just gonna continue to kinda go at the level that we've been at, given the large growth that we've had in 2021 and 2022. I'd say that's mid-single as I think about ES revenue growth in 2023. Okay, thank you. That's helpful. Secondly, Eric, just building on your comments on SKSS spread, can you just give us a little more color on your ability to manage the spread and your confidence in managing the spread in 2023? Just looking for what's maybe structurally changed for the better, whether it's your ability to manage collection costs, IMO 2020 market consolidation, or any other factors. Sure. Going back in time a little bit, we separated out our Bulk Products and Services business, and that was predominantly around the collection of used motor oil, the used loop, and selling back our direct blended products into the market. That's the organization that we talked about earlier when we announced the change with Brian Weber. By separating out that organization, we also put in a significant amount of discipline around managing how we collect used motor oil, the prices in the market that we charge or pay for that oil. Then through the re-refinery process, how we sell that direct blended oil. There's a significant amount of discipline with that organizational structure change that we've put in place. It's obviously reflective in our numbers from 2021 and 2022, we continue to have that in place today. We're very confident that our spread management processes today are better than ever, very robust. We know who we're competing against, we know the customers that we're managing, and we're very confident of our continuous to be able to manage that spread. Okay. Thank you very much, guys. Thanks, Quinn. Our next question comes from the line of Jerry Revich with Goldman Sachs. Please proceed with your question. Hi, this is Adam Bubes on for Jerry today. Thanks for taking my question. You recently announced the results of the third-party study demonstrating safe destruction of PFAS at your incinerators. Are you able to update us on how you're thinking about the PFAS opportunity in terms of tons or volumes? If incineration is designated a safe disposal method, do you need to build additional capacity beyond the Kimball Nebraska plant to capture that incremental volume? We, as mentioned, we continue to believe that high temperature thermal destruction is the best disposal technology for managing particularly contaminated soils. We do not feel that we have to build any additional capacity across our network. Our plants are very robust, and Kimball will obviously provide a complementary tonnage to managing PFAS contaminated soils. I think it's too early to tell right now and put a number on the tonnage that we would expect out of this. Regulations are still being changed, and we continue to be heavily involved in that process. We continue to communicate to all regulatory agencies on what our test has unveiled, and we're working with customers on different opportunities that they have to remediate their sites depending on how the regulatory environment plays out. Great. Can you help us think about your assumptions for base oil prices that's contemplated in the guide? Yeah, Adam. We assume that base oil pricing, you know, moderates over the course of the year. We assume that it, you know how base oil pricing work. Q1 is kind of low, Q2 is up, Q3 is up, Q4 is down. We assume that, you know, base oil pricing on average for the year will be down a bit kind of year-over-year in the guide. Great. Thanks so much. As a reminder, if you would like to ask a question, press star one on your telephone keypad. Our next question comes from the line of James Ricchiuti with Needham. Please proceed with your question. Hi, good morning, and again, congratulations to all on the career developments, Alan, particularly to you. A question I had just with respect to Thompson Industrial. I wonder if you could talk a little bit about that. Any additional color you could provide, including, you know, overlap with HPC. Yeah, Jim, this is Mike, and I'll start. Eric or Alan, please feel free to jump in. You know, we're really excited about Thompson Industrial. It brings industrial cleaning to a part of the country where we don't have a very large industrial presence like Alan mentioned. The Southeast is not an area where we have a huge IS business, so there isn't a lot of overlap today with HydroChemPSC. A small amount, but not a lot. We're excited about our ability to sell environmental services businesses into that, into those new customers and provide perhaps some cross-sell around that. As Alan said, it was about, you know, a $100 million purchase price, and that'll close, you know, probably at the end of this month. Got it. Thank you. I think it also provides us just one other thing, Jim, this is Eric. It also provides us an entrance to other markets that we haven't traditionally been in, particularly that Southeast main market, pulp and paper, as well as the utility sector. Got it. Thanks for that. Just with respect, Mike, to the comments that you made about industrial production. I mean, typically, I guess you do tend to lag some of that. I'm wondering if you're seeing any early changes in customer demand, with respect to a slowing economy. I mean, it sounds like you actually have a pretty good pipeline, but I'm just wondering if you have seen any subtle changes in the market. You know, Jim, you know, we polled the sales team, you know, yesterday. The answer is no. The pipeline remains as robust and as strong as it was back in the fall. Got it. Thank you. Just last question, if I may. you know, you mentioned, pricing and, how this also relates to customer behavior. as we go through this inflationary period, does it become any more challenging to put some of these increases across, or is there just a better understanding and appreciation of the overall environment that allows you to continue to use prices to lever when appropriate? You know, Jim, I've never had a conversation with a customer that they say kind of okie doke to price increases. It's always a discussion with, with, you know, our, you know, build up of our costs, a thoughtful discussion on value, a thoughtful discussion on customer service and timeliness. All that goes into the mix. I would say, though, that we've been very successful in, as you can see from the 2022 results, in particular Q4, of driving those price increases. I think that continues into 2023, but you know, it's never an easy conversation. The fact that there's still a fair amount of inflation has made that conversation easier. It gives us more evidence and support, but it's never an easy conversation around pricing. I'll probably mention just one other thing. I mean, with the capacity constraints that we've had, both in assets like resources for equipment, personnel, you know, there are some customers that we've had to walk away from when we've had those hard conversations and realize that, you know, we need to put our people and our equipment to work where we can kind of create the best value. That's right. We're not gonna, you know, give those services away. I think, that is some discipline, particularly on the industrial side, that we have begun to put in place that I think will start paying off for us in the future years here. That's fair. Got it. Thank you for that, and congratulations on the year. Thanks, Jim. A final reminder, if you would like to ask a question, press star one on your telephone keypad. Our next question is a follow-up from Michael Hoffman with Stifel. Please proceed with your question. I thank you for taking this. The one that probably should get asked, East Palestine, is there going to be a benefit from that after the fact? I know you didn't participate in the silliness of burning the chemicals, but is there a benefit after the fact? You know, Michael, we've participated in somewhat of the emergency response, and we've provided some solutions to the regulatory authorities, to, and to Norfolk Southern on options. We before we really manage or take any of that material, we're being very transparent with the government agencies and the governments that we have our disposal facilities in. At this point, we don't, we're not, have not started to take any volumes there. Okay. Everybody thinks PFAS is gonna be this amazing opportunity. I'm in that camp, kind of think about it like PCBs were in the eighties and early nineties, there's things have to happen before it becomes that. Can we talk about those a little bit and share with the market? You know, what does EPA have to do, and when do you expect them to do what they have to do? This is rulemaking. The second part of the question is, am I correct that all of your incineration capacity, the way the permits work, bringing this volume in is incremental and doesn't need a permit modification, and you can still do all of the hazardous waste stuff that's permitted, but this can be incremental without having to modify permits? Michael, this is Mike. I'll answer that. The you're right that it does take, you know, increased regulation to, you know, kind of the definition of kinda how clean is clean. It's hard for our customers who may have PFAS in their soil or somewhere on their sites to address the issue because there's not a clear definition of, you know, when am I done? Or what is clean? We think, like, this will take some time to get that regulations in place, and I think that PFAS will play out over decades. I think like PCBs, it will be a winner for Clean Harbors and for the industry for a very long time. To the point to your second question is can we take the soil, if you will, in our current, in our current incinerators, from a permit perspective, the answer is yes. Sometimes it's just an add-on because it's so inert. I do think there's a clear opportunity for us. We've seen it in some, in some public environments in air force bases in other areas, military bases, where we've done some of this work, and we will continue to do this work. I do think, like you, I think it's a very long-term tailwind for Clean Harbors and for the industry. Okay, thanks for taking the extra questions. Thank you, Michael. We have no further questions at this time. Mr. McKim, I would like to turn the floor back over to you for closing comments. Okay, thanks for joining us today. Mike, Eric Dugas, and Jim will be participating at the Raymond James Conference next week. As Mike mentioned, we'll be hosting our Investor Day in four weeks. I look forward to seeing some of you there in person later this month. Thanks for being here today. Ladies and gentlemen, this does conclude today's teleconference. You may disconnect your lines at this time. Thank you for your participation, and have a wonderful day.
