京津冀统一空气重污染标准 国I国Ⅱ车工作日将限行

2016-11-22 03:09:23   京华时报

昨天,最新修订的《北京市空气重污染应急预案》(以下简称“《预案》”)发布。从12月15日起,如遇空气重污染橙色及红色预警时,国Ⅰ和国Ⅱ排放标准轻型汽油车全市禁行。此外,从2017年2月15日起,本市将对本市及外埠的国I和国Ⅱ排放标准轻型汽油车,实施五环路(不含)以内道路工作日限行。据了解,该举措将涉及到本市近40万辆国I、国Ⅱ车。

京津冀统一空气重污染标准

据记者了解,北京市2012年首次发布实施空气重污染应急预案,此次已经是第四次修改。相关负责人表示,总结以往经验,针对应急预案实施中反映出的问题,按照总体措施力度不减、重点措施细化加强、局部措施优化调整的原则,对应急预案进行了修订。

按照环保部要求,京津冀统一了预警分级标准,考虑了污染物单日高浓度值的因素。对比新旧两个版本的应急预案发现,其中,蓝、黄两色预警的启动条件不变,橙色预警和红色预警标准加入了对污染物单日高浓度值的考量。

具体而言,预警启动条件为:蓝色预警为预测未来将出现1天重度污染;黄色为预测连续2天及以上出现重度污染;橙色为预测连续3天出现重度污染,其中1天达到严重污染;红色预警为预测连续4天及以上出现重度污染,其中2天达到严重污染;或单日空气质量指数(AQI)达到500时,也要启动红色预警。

按照优先削减高污染排放车的原则,橙色预警时,实施全市国Ⅰ、国Ⅱ排放标准汽油车及建筑垃圾、渣土、砂石运输车辆禁行的应急措施;红色预警在橙色预警基础上,全市其他车辆实行单双号行驶(纯电动汽车除外)。

这也意味着,新预案12月15日开始实施后,只要发布空气重污染橙色预警或者红色预警,国Ⅰ、国Ⅱ排放的车辆就禁止上路行驶,以加强机动车污染减排力度。

中小学“红警”停课由各区定

综合考虑地区空气质量差异、学校教学条件,以及学生停课涉及到的家长看护、教学安排等多方面因素,新修订的《预案》将采用差别化的应急措施。若遇重污染红色预警,以前是市教委统一宣布停课,以后则由区教育主管部门根据属地情况安排。《预案》将统一停课措施调整为由市、区教育主管部门根据属地实际情况,指导中小学、幼儿园,采取弹性教学或停课的防护措施。
