Good morning. I would like to thank everyone for joining us on this webcast to discuss Delek Logistics Partners' Q4 2021 financial results. Joining me on today's call will be Uzi Yemin, our general partner's Chairman and CEO, and Reuven Spiegel, CFO, as well as other members of the management team. As a reminder, this conference call may contain forward-looking statements as that term is defined under federal securities laws. In addition to reporting financial results in accordance with generally accepted accounting principles or GAAP, we report certain non-GAAP financial results. Investors are encouraged to review the reconciliation of these non-GAAP financial measures to the comparable GAAP results, which can be found in the press release posted on the investor relations website.
Our prepared remarks assume that the earnings press release has been reviewed and we're covering less segment and market information than is incorporated into the press release. On today's call, Reuven will begin with financial overview, I will review results, and Uzi will offer a few closing strategic remarks. With that, I'll turn the call over to Reuven.
Thank you, Blake. Our distributable cash flow was approximately $54 million in the Q4 compared to $56 million in the Q4 of 2020. Our DCF coverage ratio was 1.27 times for the Q4 compared to 1.41 in the prior year period. EBITDA was $70 million, which represents a 9% increase over prior year period. Our board approved an increase in the quarterly distribution to $0.975 per limited partner unit for the quarter ended December 31. This distribution was paid on February 8 to unitholders of record on February 1st and represents a 2.6% increase from the Q3 and a 7.1% increase from the Q4 of 2020.
At December 31st, 2021, DKL had $592 million of available capacity on our $850 million credit facility. Our total debt was $899 million, and total leverage ratio is 3.35 times, which is well within the 5.25 times currently allowable under our credit facility. Now, I will turn the call over to Blake to discuss the results.
Thanks, Reuven. In our pipelines and transportation segment, the Q4 2021 contribution margin was $50 million compared to $44 million in the Q4 of 2020. The increase was primarily attributable to higher pipeline throughput, partially offset by expenses related to pipeline integrity work. In our wholesale marketing and terminalling segment, contribution margin was $17 million in the Q4 of this year compared to $18 million in the Q4 of 2020. Results were broadly in line with year-ago levels. During the Q4 of 2021, equity income from our crude oil pipeline JVs was approximately $7 million compared to $6 million in the prior year. Capital expenditures were approximately $12.9 million in the Q4 of 2021, which consisted of $8.2 million of growth spending and $4.8 million of sustaining maintenance.
On a full year basis, our 2021 total gross capital expenditure was $27.5 million, which includes $20.2 million of growth and $7.3 million of maintenance capital. The outlook for 2022 includes total growth capital expenditures of $70.8 million, including $59 million of growth and $11.8 million of maintenance capital. With that, I will turn the call over to Uzi Yemin.
Thank you, Blake, and good morning, everybody. DKL delivered another strong performance in 2021, despite operational downtime at multiple Delek US facilities during the year. The lack of major planned turnover activity for Delek's system in 2022 could benefit DKL with strong volumes flowing throughout our assets this year. Permian activity is once again accelerating, and DKL is poised to benefit with increased demand in our gathering system. We plan to expand this asset with a step-up in growth capital in 2022. We delivered on our 5% distribution growth commitment for 2021 with the recent quarterly distribution increase. We expect another 5% increase in 2022 on a full year basis. With that, operator, can you please open the call for questions?
Yes, sir. We will now begin the question-and-answer session. To ask a question, you may press star then one on your telephone keypad. If you're using a speakerphone, please pick up your handset before pressing the keys. To withdraw your question, please press star then two. At this time, we'll pause momentarily to assemble our roster. The first question will come from Spiro Dounis with Credit Suisse. Please go ahead.
Thanks, operator. Morning, guys. First question on growth CapEx. Uzi, you just mentioned it, the $59 million. Sounds like a lot of that's gonna be directed towards the Permian gathering system. Can you give us a sense maybe for what else is actually in that number? Is that really all directed there? Just as you think about the commodity environment, I think that guidance came out in December. Commodity obviously vastly improved even since then. Curious if you see any sort of upside skew or bias to that number as the year progresses.
Okay. Spiro, first of all, good morning. The $59 million number essentially is all toward the DPG, with few exceptions but very few of them. Now, let me share with you what we see in the Permian. It's basically moving toward, for the most part, existing producers that came with their plans and shared them with us, and per our agreements with them, we're going to accommodate them. Now, if there will be new producers, which we believe there will be more dedicated acreage in the future because of everything that is going on, that number may go higher.
We just need to remember that with $100 or $90 or $80 environment, the spread, the gathering spreads are getting better. We are meeting handsomely our 15%, 17% threshold. Just to give you a point of reference, I know that everybody's trying to guess what will be the production in 2022. We see until a week ago, which probably may change now to the upside. If you look at the press release, we were gathering 83,000 barrels in the Q4 . In the Q1 , we're already 125 or so catering to trucking because we need to build the fleet infrastructure.
We expect in the Q4 as we exit the year, as of two weeks ago, 10 days ago, because we haven't updated the numbers with producers to double that 83 number and go over 160,000 exiting 2022. Essentially, in our case, doubling production within the year was our idea until 10 days ago.
That's helpful color. Thanks, Uzi. Second question, just going to something from the DK press release. It talked a little bit about some opportunistic divestitures of the DKL stock. That probably continued to happen just given the success of that program so far. I guess, just curious, you know, is there a target ownership level that you all have in mind at DK? Really just any color there on how you're thinking about executing these divestitures would be helpful.
Well, you know, we said to ourselves $43, $44 is a good number. We obviously have limits to the downside if something happens to the units, but so far it's holding, okay. I think we actually have an upside based on today's numbers and the color we're providing both on the DPG thing and also the Slurry project. We will continue to do that. We don't think that we should be holding 79%, 80%. We'll do that in a timely manner. You probably saw DK press release. There's no need of cash over there. As a matter of fact, prices of crude going up, so working capital will continue to be very positive for DK.
We, we'll do that as long as we think there's value in it. Certainly we don't think that it's 80% is the right number. I don't see us going out with big blocks anytime soon. We'll just do it in a timely manner under the ATM program.
Got it. Okay. That's helpful. Last one, if I could sneak it in. Just with respect to some of the customer contracts, looks like you had a few expire in November in Greenville. I think there's a few more coming up in April at Big Spring. Just looking for any color you can provide in terms of how to think about the impact, the renewal process, and anything you can share on those.
Sure, Spiro. Hey, good morning. It's Odely . Basically, all those contracts are gonna be renewed and working toward also our Conflicts Committee between both DK and DKL. We don't expect to have really an impact either from the associated volume that we are seeing over there and also what we've seen so far and also from the fee standpoint. Really, we don't see any impact going forward for those two.
Got it. That's great. That's all I had today, guys. Thanks for the time.
Thanks, Spiro.
Again, if you have a question, please press star then one. This concludes our question and answer session. I would like to turn the conference back over to Uzi Yemin for any closing remarks. Please go ahead, sir.
Okay. Thank you so much. I'd like to thank my colleagues around the table. I'd like to thank the board of directors and you investors and analysts for your interest in our company. This was a unique year for DKL. We actually performed very well in the stock market, but at the same time, we or also at the same time, we built the foundation for future growth. I think the price of crude and the things that are happening in the energy sector, especially in the Permian, should benefit us. Mostly, I'd like to thank each one of the employees of this great company. Have a great day, and we'll talk to you soon. Thank you.
The conference is now concluded. Thank you for attending today's presentation. You may now disconnect.
