Core Viewpoint - The Henan Provincial Department of Natural Resources has issued detailed implementation rules to enhance ecological restoration incentives while strictly regulating the use of stone and soil materials, aiming to prevent illegal mining under the guise of restoration [1][2]. Group 1: Project Approval and Regulation - The new rules establish a negative list for project approval, prohibiting the packaging of construction, mineral resource development, and coalfield fire hazard management as ecological restoration projects [1]. - Existing mining land intended for development will not have restoration projects set up and must follow construction project approval procedures [1]. - Projects involving the sale of sand and gravel must comply with regulations for construction projects [1]. Group 2: Utilization of Stone and Soil Materials - The rules impose strict constraints on excavation activities, stating that no new excavations are allowed in restoration areas, and existing pits cannot be deepened [1]. - Any necessary slope reduction must be evaluated by qualified geological disaster prevention units [1]. - Remaining stone and soil materials must undergo asset evaluation and government pricing before being publicly sold, with all proceeds going to the treasury [1]. Group 3: Approval and Incentive Measures - The rules eliminate the need for separate soil and stone utilization plans for restoration projects, integrating these into the ecological restoration plan [2]. - Restoration plans involving the sale of stone materials must be reviewed by local natural resource departments and approved by county-level governments [2]. - The rules encourage the use of mining solid waste for soil improvement and allow for the re-establishment of mining rights for eligible abandoned mines [2]. Group 4: Accountability and Oversight - A three-tiered regulatory system is established to address illegal mining and improper disposal of stone materials, with measures including rectification orders and criminal liability [2]. - The rules promote the establishment of integrity archives and the implementation of credit penalties for violations [2].
