Thanks, Gary. We've been very eager to move forward this combination since MPC's acquisition of Andeavor and are enthusiastic about the opportunities it brings to the partnership. This merger fosters a more powerful presence in key producing regions and enhances our commercial opportunity to capture market trends.
Turning to Slide 7, let me remind you the strategic priorities we outlined at Investor Day. Key tenet of our strategy is capturing the full midstream value chain by connecting growing crude, NGL and natural gas production to the global market. To accomplish this, we will continue to prioritize long-haul pipelines and export infrastructure, which will provide enhanced long-term cash flow stability. These projects benefit from our ability to leverage existing assets. We expect the Permian basin to be a source of long-term growth for our expanded midstream business and expect to be an active player providing logistics solutions in the basin. We will continue to leverage the relationship with MPC to enhance projects through volume commitments and providing efficient and value-added logistic solutions for MPC's nationwide platform. We continue to believe in the Marcellus as an attractive growth opportunity and pursuing discipline, just-in-time investments to support our producer customers in the region. We believe that the Northeast has the lowest cost structure for pure-play natural gas production in the U.S, which provides additional opportunities for processing investments. We've seen consistent volume growth in our Northeast footprint and expect this trend to continue. As we deploy capital, we're focused on financial discipline, including maintaining our investment-grade credit profile, targeting mid-teens returns on our growth investments and maintaining a self-funding strategy for the equity portion of our capital investment.
Moving to Slide 8, we are especially enthusiastic about the combined presence in the Permian basin. A powerful combination of gathering, processing and long-haul pipeline infrastructure and services across the hydrocarbon value chain including crude, natural gas and NGLs. This combination strengthens our ability to participate in integrated downstream projects with a number of key partners. We have a number of organic projects in development that have strategic rationale to bring third-party revenues into the enterprise and/or create a synergy with MPC.
On Slide 9, we highlight our Gathering and Processing opportunities in the Permian. We are excited to add the Conan crude oil gathering systems to our Permian footprint, which will supply 2 key crude pipelines under development: Gray Oak and Wink-to-Webster. ANDX' Conan system currently has 250,000 barrels per day of capacity and is expandable up to 500,000 barrels per day. On the natural gas side, we're developing a super system, very similar to what we have up in the Northeast. We have 2 plants currently running, Argo and Hidalgo, and have 3 additional processing plants in various stages of development, including the Torñado plant which is targeted for completion in the third quarter of this year. The combined broader footprint will allow us to build on existing producer relationships and capture expanded commercial opportunities.
As shown on Slide 10, we've signed an LOI to partner in the announced Exxon, Plains, Lotus Wink-to-Webster project. As we've discussed before, we were previously evaluating the PGC Pipeline project. Although we had sufficient commitments to proceed with PGC, we decided to join the larger Wink-to-Webster project as a way of delevering -- I'm sorry, the way of delivering capital efficiency and the opportunity to achieve a much higher return on invested capital. Pipelines plans to have origination points in Wink and Midland, Texas with the capacity of approximately 1.5 million barrels per day. Pipeline plans to have destination points in Houston market including MPC's Galveston Bay refinery in Texas City. Our expectation is that we will have an approximately 15% equity in the project, which is targeted to be in service in the first half of 2021.
On Slide 11, we highlight our planned natural gas and NGL pipelines in the Permian. The natural gas takeaway project is called Whistler Pipeline, the 42-inch, 2 billion cubic feet per day pipeline that would transport natural gas from Waha to Agua Dulce. The NGL pipeline is called BANGL, which stands for Belvieu Alternative for NGLs. We plan to move NGLs from the Permian basin to the Sweeney area where fractionation will occur, ethane will be consumed in the local areas at start, propane will be exported and the butanes and gasolines will be optimized or exported. BANGL has a planned initial capacity of approximately 500,000 barrels per day and is expected to be operational in early 2021. We've made significant progress on both Whistler and BANGL since originally announcing them last year, we are finalizing documentation with counterparties and expect to announce a final investment decision in the very near future.
On Slide 12, we have 5 export facilities operational or under development along the Gulf Coast to provide the ability to meet global demand for U.S. production and enhance our ability to generate third-party revenue. We are enthusiastic about the prospects for the South Texas Gateway terminal, which will provide crude export opportunities for shippers on Gray Oak and other pipelines. Additionally, MPLX completed an open season on the reversal of the Capline pipeline, which is partially owned by MPC. We're very happy to report that we've received significant shipper interest for both light and heavy crude, providing the opportunity to move forward with plans to start light oil deliveries in September of 2020 and heavy oil deliveries in 2022. This project will allow Cushing supply to reach the Eastern Gulf and open the ability to export crude via Louisiana Offshore Oil Port, commonly referred to as LOOP. To conclude, we remain intensely focused on investing in high-return projects while maintaining financial discipline. Partnering on the various Permian pipelines we discussed, demonstrates our capital-efficient approach to investing. By consolidating the investment program of both partnerships, we will have the opportunity to be even more selective with our investments. Let me now turn the call over to Pam to cover some of MPLX first quarter highlights.
