重慶黔江民生燃氣（集團）有限公司：

你單位報送的《黔江芭拉胡景區天然氣管道隱患整改及技改工程水影響論證報告審批申請書》及相關資料收悉。根據河道管理有關法律法規和專家評審意見，現批復如下：

一、原則同意本次評價范圍

本次評價涉及原行政審批類別為“在河道管理范圍內的建設項目”。該項目在咸黔界與忠縣-石柱－黔江輸氣管道（活龍坪-大路支線）大路分輸站與站外分輸管道接口，途經小南海鎮、中塘鎮、舟白街道、正陽街道及馮家街道，最后抵達位于馮家街道照耀居委的分輸閥室，新建輸氣管道全長37km。涉河管道沿河布置共計3509.54m，均位于段溪河范圍內，左岸沿河敷設長度2926.24m，右岸沿河敷設長度為583.3m；穿河管道共計636.90m，其中段溪河穿河5次，穿河長度總計487.2m，黔江河穿河1次，穿河長度94.7m，團結河穿河1次，穿河長度55m。工程防洪標準為50年一遇。

本次評價范圍為：

段溪河：段溪河上游河段評價范圍起于勝利村龍口村小學下游 1km 處，止于工程起點斷面，評價河段總長 4.292km ；段溪河下游河段評價范圍起于雙泉電站下游 400m 處電站攔河壩，止于中塘場鎮下游干旱嶺公路橋，評價范圍總長3.39km。

黔江河：起于黔江河河口，止于河口上游 895m ，評價河段總長 0.895km。

?團結河：起于團結河河口，止于河口上游 534m ，評價河段總長 0.534km。

本項目控制坐標（CGCS2000）如表1所示：
