一、原则同意本次评价范围

本次评价涉及原行政审批类别为“在河道管理范围内的建设项目”。该项目在咸黔界与忠县-石柱－黔江输气管道（活龙坪-大路支线）大路分输站与站外分输管道接口，途经小南海镇、中塘镇、舟白街道、正阳街道及冯家街道，最后抵达位于冯家街道照耀居委的分输阀室，新建输气管道全长37km。涉河管道沿河布置共计3509.54m，均位于段溪河范围内，左岸沿河敷设长度2926.24m，右岸沿河敷设长度为583.3m；穿河管道共计636.90m，其中段溪河穿河5次，穿河长度总计487.2m，黔江河穿河1次，穿河长度94.7m，团结河穿河1次，穿河长度55m。工程防洪标准为50年一遇。

本次评价范围为：

段溪河：段溪河上游河段评价范围起于胜利村龙口村小学下游 1km 处，止于工程起点断面，评价河段总长 4.292km ；段溪河下游河段评价范围起于双泉电站下游 400m 处电站拦河坝，止于中塘场镇下游干旱岭公路桥，评价范围总长3.39km。

黔江河：起于黔江河河口，止于河口上游 895m ，评价河段总长 0.895km。

团结河：起于团结河河口，止于河口上游 534m ，评价河段总长 0.534km。

本项目控制坐标（CGCS2000）如表1所示：
