石油设备网讯 据Oil & Gas Journal网站3月13日消息 美国环境保护署与3月12日正式提议，允许在全年销售含15%乙醇的汽油，此举受到玉米乙醇供应商的欢呼，但受到炼油厂的谴责，美环署还提议修改部分可再生能源认证码（RIN）计划，该计划表示，这一举措将使生物燃料信贷更加透明，并防止价格操纵。
环保署管理人员Andrew Wheeler说：“根据特朗普总统的指示，环保署正致力于在夏季驾驶季节提出并最终确定这些变化。”环保署称：“我们将在本月底举行一次公开听证会，收集重要的反馈意见。”听证会将于3月29日上午9点在密歇根州伊普西兰蒂伊格尔克雷斯特的安娜堡Marriott Ypsilanti酒店举行。
拟议的规则制定将允许E15全年销售，无需额外的里德蒸汽压力（RVP）的限制，从而在8个冬季月份销售。环保署表示：“1-psi豁免允许的汽油-乙醇混合物具有比《清洁空气法》和相应挥发性法规所允许的更高的RVP值，该法规禁止汽油的RVP在夏季超过9.0 psi。”
拟议的规则制定者指出：“目前，只有乙醇和汽油的混合物（按体积计乙醇含量至少为9%且不超过10%）才被授予1-psi豁免。”。

EPA proposes year-round sales of E15 gasoline, RIN program changes
The US Environmental Protection Agency formally proposed allowing year-round sales of gasoline with 15% ethanol on Mar. 12, a move which corn ethanol suppliers cheered and oil refiners condemned. It also proposed modifying parts of its Renewable Identification Number (RIN) program which it said would make the biofuel credits more transparent and deter price manipulation.
“Consistent with President [Donald] Trump’s direction, EPA is working to propose and finalize these changes by the summer driving season,” EPA Administrator Andrew Wheeler said. “We will be holding a public hearing at the end of this month to gather important feedback.” The hearing will start at 9 a.m. CST on Mar. 29 at the Ann Arbor Marriott Ypsilanti at Eagle Crest in Ypsilanti, Mich., EPA said.
The proposed rulemaking would allow E15 to be sold year-round without additional Reid Vapor Pressure (RVP) controls instead of during 8 wintertime months. “The 1-psi waiver allows gasoline-ethanol blends to have a higher RVP3 than would be allowed under [Clean Air Act Section] 211(h)(1) and the corresponding volatility regulations, which prohibit the RVP of gasoline from exceeding 9.0 psi during the summer,” it said.
“Currently, only blends of ethanol and gasoline containing at least 9% and no more than 10% ethanol by volume (E10) are granted the 1-psi waiver,” the proposed rulemaking noted.
