accelerate the problem. Pervasive capacity shortfalls throughout the United States would have obvious and tremendous national security ramifications. Granting the requested Presidential Exemptions to SER, and other generators like it, would be in the best national security interests of the United States for a number of reasons, including a secure, reliable power grid, the ability to power the growth of our domestic economy, and unique to our industry, the improvement of land, water, and air while protecting natural resources necessary for sustaining our population. Above and beyond that, our industry is heavily-involved in REE/REM research and analysis with NETL/DOE/Academia. We have worked on a variety of projects exploring the viability of a variety of feedstocks which could all be candidates for decreasing our reliance on foreignsourced REE/REM. Therefore, it is in the United States' national security interests to ensure the viability and continuity of base load power generation facilities, like SER, in order to provide reliable and constant power to our industries and communities. SER appreciates the opportunity to make this request; if there are any questions or additional information required, please contact me at A Fluw;116!)cilli-n2en(.'r_gy.coin. Thank you for your consideration of our request for Presidential Exemption from the MATS Rule.
