Mandatory Phosphate Waste Disposal 2019

The Mandatory Phosphate Waste Disposal layer contains the conceptual boundaries of the Waste Disposal parcels within all active mandatory phosphate mines in Florida by the year 2019. 'Mandatory Phosphate Mines' does not indicate that the area is required to be mined for phosphate; 'Mandatory' refers to the regulatory status of the land. Land mined for phosphate since July 1, 1975 is 'Mandatory,' and is required by Florida law to be reclaimed (contoured and re-vegetated). Land mined prior to July 1, 1975 was not required to be reclaimed. This layer provides the mine boundary for mines that are subject to the regulatory requirements of Chapter 378, Part III, F.S. and/or Chapter 373, Part IV. F.S. and Chapter 62C-16, F.A.C. Mandatory phosphate mining occurs primarily in the central Florida phosphate mining district in Polk, Hillsborough, Manatee, and Hardee counties and one mine in North Florida in Hamilton County. This layer was designed to provide the Mining and Mitigation Program with a graphical representation of the Mandatory Phosphate boundaries for planning and management purposes. Because this data is a work in progress, it may contain errors such as missing features, outdated features, overlapping features, erroneous status of features, variations in accuracy, or attribute errors. This layer was created and maintained by the Florida Department of Environmental Protection, Program Support.强制磷酸盐废物处置图层（Mandatory Phosphate Waste Disposal layer）涵盖了截至2019年佛罗里达州所有在用强制磷酸盐矿范围内的处置地块概念边界。"强制磷酸盐矿"并非指该区域必须开展磷酸盐开采活动，其中"强制"二字指代土地的监管属性。1975年7月1日之后开采磷酸盐的土地属于"强制"范畴，依据佛罗里达州法律，此类土地需进行复垦作业（包括地形整理与植被重建）。1975年7月1日前开采的磷酸盐用地则无复垦要求。本图层为符合《佛罗里达州法典》（F.S.）第378章第三部分、第373章第四部分以及《佛罗里达州行政法典》（F.A.C.）第62C-16章监管要求的矿山提供矿区边界信息。强制磷酸盐采矿活动主要分布于佛罗里达州中部的磷酸盐矿区，涉及波尔克（Polk）、希尔斯伯勒（Hillsborough）、马纳蒂（Manatee）与哈迪（Hardee）县，另有一处矿山位于佛罗里达州北部的汉密尔顿（Hamilton）县。本图层的设计目的是为采矿与缓减项目（Mining and Mitigation Program）提供强制磷酸盐矿区边界的可视化展示，以支撑规划与管理工作。由于本数据仍处于迭代完善阶段，可能存在各类误差，包括要素缺失、要素过时、要素重叠、要素状态错误、精度偏差以及属性错误。本图层由佛罗里达州环境保护部项目支持办公室创建并维护。
