Passage 2:The Uranium Mill Tailings Radiation Control Act (1978) is a United States environmental law that amended the Atomic Energy Act of 1954 and authorized the Environmental Protection Agency to establish health and environmental standards for the stabilization, restoration, and disposal of uranium mill waste. Title 1 of the Act required the EPA to set environmental protection standards consistent with the Resource Conservation and Recovery Act, including groundwater protection limits; the Department of Energy to implement EPA standards and provide perpetual care for some sites; and the Nuclear Regulatory Commission to review cleanups and license sites to states or the DOE for perpetual care. Title 1 established a uranium mill remedial action program jointly funded by the federal government and the state. Title 1 of the Act also designated 22 inactive uranium mill sites for remediation, resulting in the containment of 40 million cubic yards of low-level radioactive material in UMTRCA Title 1 holding cells.
Passage 3:Despite the weakness of the Song military, they managed to slow the Mongol Empire advance for decades. The Song resistance led to the death of Mongke Khan, in 1259, at Diaoyu Fortress. The resulting withdrawal of the Mongol forces, for the customary kurultai to select a new Khan, ultimately led to the Toluid Civil War which divided the Mongol Empire. Mongke's brother, Kublai Khan, who already controlled Mongolia and China's northern territories, formerly part of the Jin Empire, declared himself Emperor of China and founded the Yuan dynasty. Kublai renewed the Mongol campaign against the Song eventually capturing the fortified cities of Fancheng, and Xiangyang during the Battle of Xiangyang in 1273, allowing his armies to advance deep into Song territory and seize its capital. On 19 March 1279, the Song chancellor Lu Xiufu committed suicide with the eight-year-old Zhao Bing after the defeat of the remaining Song forces at the Battle of Yamen bringing an end to the Song Dynasty and marking the beginning of a century of Mongolian rule over China before the establishment of the Ming Dynasty by the House of Zhu and a return to Han rule.
