关于大英红旗化工园区周边土地规划
安全控制线的划定说明
一、大英红旗化工园区周边土地规划安全控制线划定依据
根据《化工园区安全风险排查治理导则》第3.5条规定：化工园区安全生产管理机构应依据化工园区整体性安全风险评估结果和相关法规标准的要求，划定化工园区周边土地规划安全控制线，并报送化工园区所在地设区的市级和县级地方人民政府规划主管部门、应急管理部门。第3.6条规定：化工园区所在地设区的市级和县级地方人民政府规划主管部门应严格控制化工园区周边土地开发利用，土地规划安全控制线范围内的开发建设项目应经过安全风险评估，满足安全风险控制要求。
因此，主要依据包括：
（一）不小于相关标准规范规定的安全间距。
（二）不小于园区现有、在建项目3×10-7/年个人风险等值线的范围。
（三）综合考虑相关重大事故后果影响范围。
二、大英红旗化工园区周边土地规划安全控制线划定
（一）根据大英红旗化工园区现有及在建项目进行的区域风险评估，结果为3×10-7/年个人风险等值线影响范围超出园区范围最远距离约580m；重大事故后果模拟影响范围均未超出园区范围。
（二）根据国家现有法规《公路安全保护条例》第18条有关安全间距的规定，园区现有企业离公路距离要求100米。
（三）根据《石油化工企业设计防火标准（2018年版）》GB50160-2008第4.1节“区域规划”中有关石油化工企业与周边设施的间距要求，由于园区企业装置建设内容的不确定性，取其中最严格的液化烃罐组与周边相邻设施（居住区、公共福利设施、村庄等）的防火间距标准（300米）作为依据。
（四）由于化工园区内装置布置位置的不确定性，一律采用园区边界作为计算起点。
综上，为提高大英红旗化工园区安全管理水平、强化重大安全风险防控，有效遏制防范重特大事故，以现有化工园区边界为起点，向东、西、南、北侧延伸500米范围，综合考虑3×10-7/年个人风险等值线影响范围，园区边界西侧最远延伸700米，划定大英红旗化工园区周边土地规划安全控制线。详见附件2。
