北京发布最严“停工令”:采暖季城六区停止土方作业

2017-09-17 09:46:38   央广网

央广网北京9月17日消息(记者刘飞)据中国之声《新闻纵横》报道,9月15日,北京接连向大气污染放出两个大招儿。最新的2017年版修订版《北京市空气重污染应急预案》公布实施,对制造业企业实施停产限产措施的条件,由上一版的“橙色预警”调整为“黄色预警”。

另外,北京市住建委印发《2017-2018年秋冬季建设系统施工现场扬尘治理攻坚行动方案》。今年11月15日到明年3月15日,这4个月间,北京城六区全部区域以及通州区等十个区和亦庄经济技术开发区的城区、建成区内,将停止各类道路工程、水利工程等土石方作业和房屋拆迁施工等。

有媒体评价这是北京“最严停工令”。“最严停工令”加上更严格的强制性减排措施,这能“松掉”北京秋冬季的口罩吗?

本月初,环保部大气环境管理司司长刘炳江就明确指出,今年冬季对各地重污染天气应对方面做出较为严格要求,以北京为例,PM2.5平均浓度需同比下降25%,重污染天数同比下降20%。

环保部最新通报显示,截至9月14日,环保部派出的大气污染防治强化督查组已完成了11轮次督查工作。9月1日到14日,是“京津冀及周边地区2017-2018年秋冬季大气污染综合治理攻坚行动”强化督查的第1个轮次。

9月15日,距离上次修改不到一年时间,北京再次更新了《北京市空气重污染应急预案》。和上一版相比,提出的强制性减排措施更加严格。

在启动蓝色预警时,新版应急方案增加了“在常规作业基础上,对重点道路每日增加1次清扫保洁作业”以及“停止室外建筑工地喷涂粉刷、护坡喷浆施工作业”2条强制性减排措施。在上一版中,未做这样的要求。

此外,在上一版中,要启动橙色预警时,才会对涉及的制造业企业采取停产限产措施。而此次要求,启动黄色预警时,就实施。

国务院发展研究中心资环所副所长、研究员常纪文介绍,10月中旬之后,北京一些地方开始进入采暖季节,大气污染物的主要类型第一是PM2.5、PM10,第二个是氮氧化物、硫氧化物、挥发性有机物。第三个就是扬尘。

国家环境保护督察办公室副主任刘长根指出,当前,影响京津冀及周边地区大气环境质量的突出矛盾,有“散乱污”企业整治不力;电代煤、气代煤工作不实;小锅炉“清零”不到位;重点行业错峰生产不落实。

而除了改善、解决这些问题措施外,9月15日,北京住建委发文,进一步加大房屋建筑及市政基础设施工程施工现场的扬尘治理力度,以打好“蓝天保卫战”。当中明确提出,北京城六区全部区域以及通州区等十个区和亦庄经济技术开发区的城区、建成区内,将从11月15日起,停止各类道路工程、水利工程等土石方作业和房屋拆迁施工等。为期4个月时间。

常纪文介绍,扬尘产生的污染物主要是大气颗粒物,“扬尘在城市里对局部产生雾霾的影响还是较大的。建筑工地,包括河道施工,就有土石方开挖问题。土石方的开挖容易产生扬尘,这还是比较厉害的。所以,北京这次对建筑工地的一些行为予以限制。但没有限制所有的建设行为,例如,正常封闭化施工的建设行为没有制止。”

今年我国冬季的情况会如何?对此,环境保护部大气环境管理司司长刘炳江表示,这跟气象条件有紧密的关系。无论如何,今年布置的大气污染物减排任务量是去年的两倍多,接近三倍。去年执行力不像今年是压迫式的执行力,相信今年的减排量非常大。
