围绕修改《山东省海洋环境保护条例》听取各界人士意见建议 条例修订草案明确，省海洋与渔业执法监察机构集中行使原由多个部门承担的海洋监察相关行政处 罚权、行政检查权及行政强制措施权。 烟台市海洋与渔业监督监察支队副支队长宗绪斌直言，这是一大创新亮点。这一授权实现了海洋执 法"多支队伍"向"一支队伍"转变，有助于优化资源配置，强化海洋生态保护职责，符合现代海洋治理趋 势。他还提出建议，条例修订草案应参照省级授权的模式，对沿海市、县海洋执法权限予以规范。"目 前，市、县两级海洋环境保护执法实行委托执法，缺乏统一规范和稳定性，仅授权省级集中行使海洋执 法权，难以发挥省、市、县三级海洋执法机构合力。" "入海排污口'全链条治理体系'建设面临哪些难点，如何厘清排污口责任主体的监管职责？"从事污 水处理工作30余年，青岛李村河北岸水务有限公司总经理刘东旭结合工作实际和体悟，围绕这一听证内 容提出了建议：建立全链条治理体系，责任主体复杂多样，有地方政府、企业、事业单位、养殖户个体 等，应配套出台相关责任划分制度；同时，进一步完善技术标准，强化科技支撑。 再次对这部护海法规进行修改，势在必行。坚持问题导向、强化系统思维，此次立法 ...
