Thanks Chuck. We are encouraged by the pickup and activity we have witnessed to begin the year. As Chuck indicated, first quarter 2021 volumes are up 25% from fourth quarter, 2020 levels, despite weather challenges for the industry in February. March volumes were up 48% from February levels as there was catch-up from the weather impact, but overall activity also increased. We are seeing strong demand continue into the second quarter. We remain committed to low leverage levels, a prudent capital structure, generating positive free cashflow for the year and maintaining adequate liquidity levels. Now I will go through some of the highlights of the first quarter compared to our fourth quarter, 2020 results. Starting with sales volume, we sold 762,000 tons in the first quarter of 2021, a 25% increase over the fourth quarter, 2020 volumes of 612,000 tons. We continued to expand our customer base during the first quarter. We believe a more diverse customer base will strengthen our opportunities for growth. Total revenues for the first quarter of 2021 were 27.5 million compared to 25.3 million in the fourth quarter, 2020. Sand revenues were higher in the first quarter due primarily to an increase in the number of tons sold from both Oakdale and Utica. Our cost of sales for the quarter were 32.4 million compared to three 33 million last quarter. We were able to effectively keep our production costs flat quarter to quarter while increasing our sales volumes by 25% through increased utilization of our asset base and proactive management of our inventory levels. Total operating expenses were 6.1 million compared to 13.3 million last quarter. Operating expenses were mainly lower as a fourth quarter, 2020 included a 5.1 million impairment charge on our Permian basin long lived assets. And at 1.3 million sales tax audit settlement charge. In the first quarter of 2021, we recognized a 7.5 million income tax benefit compared to an 18.6 million income tax benefit, last quarter. The fourth quarter benefit included a 7.8 million benefit related to the anticipated benefit to be received from the carry back and net operating losses, including those related to depletion to tax years with a 35% corporate rate. In the first quarter we had a net loss of 3.9 million or 9 cents per basic, and diluted share compared to a net loss of 2.9 million or $0.07 per basic and diluted share for the fourth quarter of 2020. A higher net loss in the first quarter of 2021 as compared to the fourth quarter of 2020 is due to the higher income tax benefit recognized in the fourth quarter of last year. For the first quarter, 2021 contribution margin was 1 million and we had negative adjusted EBITDA of 3.5 million compared to fourth quarter negative contribution margin of 2 million and negative budget adjusted EBITDA of 7.4 million. The increase sequentially was driven by an increase in tons sold while efficiently managing our operating costs. For the first quarter, 2021, we had 1.7 million in free cashflow generating 3.9 million in operating cash flows while spending 2.2 million on capital investments. Capital investments in the first quarter have primarily been on new smart systems units. During the quarter, we didn't use our revolver and still have no outstanding borrowings other than 1.2 million in letters of credit. Our current unused availability is 15 million. We paid down 1.7 million against our notes payables and equipment financing's in the quarter. Additionally, we have 5 million in unused availability from the acquisition liquidity support facility we put in place with the Eagle [indiscernible] business acquisition. We ended the first quarter with approximately 11.4 million cash and our current cash balance is approximately 10 million. Between cash and our availability and our facilities we currently have approximately 30 million in available liquidity. We do not expect to have any borrowings on our ABL revolver in the second quarter. In terms of guidance for the second quarter, we expect sales volumes to be up five to 10% from first quarter levels. We continue to anticipate capital expenditures for 2021 to be in the 10 to 15 million range and expect pre cashflow to be positive for the full year. This concludes our prepared comments, and we will now open the call for questions.
