美国环保局最高水质官员Peter Silva将在下月离开环保局。美国环保局行政长官Lisa Jackson在1月14日的一份备忘录中说Silva从水资源办公室长官助理职位辞职，他将回到位于加利福尼亚的家中。

      Silva在获得参议员的批准后，从2009年7月下旬任职至今。Jackson在备忘录里提到："在Pete的任职期间，他在保护饮水安全和护卫数百万的美国民众身体健康方面采取了许多重大举措。"

      他在新年第二周否决了维吉尼亚州西部煤炭采矿业向山顶延伸的提议。这项否决得到了环保组织的支持，同时也引起了工业集团和州煤矿立法者的愤怒。

      在环保局寻找接任者期间，水利办公室长官副助理Nancy Stoner将接手Silva的工作。Jackson说Stoner在来环保局之前是自然资源保护委员会的水资源倡导者。

      Jackson提到还有一些人要离职。前国会工作人员Joel Beauvais将成为环保局高级法律顾问。他来自白宫能源贸易委员会下属小组--能源与环境小组委员会。

      Edward Markey在民主党执政期间担任小组委员会长官，Beauvais在Markey的能源独立与全球变暖特别委员会中担任顾问。在共和党执政后，委员会今年解散。

     Jackson还任命Bicky Corman担任政府办公室长官副助理。Corman过去在环保局工作，之后在哥伦比亚地方政府任职，她担任的是华盛顿环境部总顾问。她还曾担任美国司法部环境执法分部的律师，当过参议员Frank Lautenberg的环境工作人员。

      Top EPA water official resigns

     By Ben Geman - 01/14/11 01:52 PM ET

     Peter Silva, the top water quality official at the Environmental Protection Agency, is leaving EPA next month.

     EPA Administrator Lisa Jackson, in a memo to staff on Friday, said Silva is stepping down as assistant administrator for water and will return to his home and family in California.

     "During his tenure, Pete has led a wide range of important actions to help protect the water we drink and safeguard the health of millions of? Americans," Jackson said in the memo. Silva began the job in late July of 2009 after winning Senate confirmation.

     Silva's highest-profile action came this week, when he vetoed a large mountaintop removal coal mining project in West Virginia, which prompted cheers from green groups and outrage from industry groups and coal-state lawmakers.

    Nancy Stoner, the deputy assistant administrator for the Office of Water, will fill Silva's shoes on an acting basis while EPA seeks a replacement, Jackson said. Stoner, before coming to EPA, was a water advocate with the Natural Resources Defense Council.

     Jackson also announced some other personnel moves. Joel Beauvais, a former Capitol Hill staffer, is joining EPA as senior adviser in the Office of General Counsel. He comes to EPA from the Subcommittee on Energy and Environment, a panel under the House Energy and Commerce Committee.

     Rep. Edward Markey (D-Mass.) headed the subcommittee when the Democrats ran the House. Beauvais was also an adviser for the Select Committee on Energy Independence and Global Warming, which Markey led. Republicans dissolved the committee upon taking control of the House this year.

     Jackson also appointed Bicky Corman as deputy associate administrator for the Office of Policy. Corman, who has worked at EPA in the past, is leaving the Government of the District of Columbia, where she was general counsel for D.C.'s Department of the Environment.

     She has also been an attorney for the Justice Department's environmental enforcement section and an environmental staffer for Sen. Frank Lautenberg (D-N.J.).
