Description: Title IV of the Surface Mining Control and Reclamation Act of 1977 (SMCRA, Public Law 95-87) established the national Abandoned Mine Land (AML) Reclamation Program under the Office of Surface Mining Reclamation and Enforcement (OSMRE), U.S. Department of the Interior. The program was developed to reclaim land and water resources adversely affected by past coal mining and left abandoned or inadequately restored. SMCRA levied fees on active coal mining to pay the reclamation costs. In Ohio, the Division of Mineral Resources Management (DMRM) administers the federal AML program to reclaim those areas disturbed by coal mining operations and for which there is no continuing reclamation responsibility by a mine operator. During the years immediately following enactment of the SMCRA, OSM, states, and Native American tribes conducted surveys of eligible lands and waters and created individual inventories of problems to be addressed under Title IV. Ohio's initial inventory was completed in 1981. In 1990 SMCRA was amended and OSM was required to maintain a national inventory of high priority abandoned coal sites and provide standardized procedures for states and tribes to use in updating the data. The need for an automated nationwide inventory lead to the creation of Abandoned Mine Land Inventory System, or AMLIS, a compilation of the individual state, tribe, Federal Reclamation Program (FRP), and Rural Abandoned Mine Program (RAMP) inventories. The AMLIS documents counts for various problem types and the costs to remedy those problems. The system captures estimated unfunded costs, estimated construction costs when funding is made available for remediation projects, and the actual costs for completed constructed projects. It is used in support of AML work plan development, to record the work completed under each regulatory authority (RA) AML program, and report the extent and cost of AML problems remaining. Delineations of AMLIS Planning Units (PU) are unique to the state/regulatory authority under SMCRA. For Ohio, PU's are representative of watersheds in areas where coal reserves occur in Ohio. Initial creation of the PU delineations were completed by the Ohio Department of Natural Resources (ODNR), Division of Mineral Resources Management (DMRM) circa 1980 and formed from Water Cataloging Unit (WCU) boundaries where one PU may comprise an entire WCU or may be a subdivision of one. Ohio's PU boundaries were originally sketched on 7 ½ -minute quadrangle topographic and mylar maps which were subsequently scanned and georeference when creating the PU GIS polygon data. When a GIS component was added to the national Abandoned Mine Land Inventory System (AMLIS) circa 2000, the system defaulted state PU's to USGS Hydrologic Units boundaries. Thus, the Ohio PU boundaries currently in the national AMLIS are not representative of actual Ohio PU delineations. This PU data was developed in 2008 to correct the PU designation errors in AMLIS and create an accurate Ohio PU layer for interoffice use and public distribution. Ohio anticipates future modernization of the national AMLIS will allow this data to be incorporated to reflect accurate Ohio PU designations. The PU GIS polygon data was created by merging watersheds using a copy of 14-digit HUC watershed boundary spatial data. The 14-digit data was developed by the United States Department of Agriculture (USDA), Natural Resources Conservation Service (NRCS), and created from 7 ½-minute topographic quadrangle maps published by the United States Geological Survey (USGS). One Ohio PU may be composed of a single 14-digit watershed or a combination of adjacent 14-digit watersheds. When PU boundaries intersected USGS watershed boundaries, the description of rivers or creeks, and/or the drainage point of the watershed were taken into consideration when determining the Ohio PU boundary. For example, delineations for North Fork Little Beaver PU and Bull Creek PU divided a 14-digit watershed boundary. Since the description of the divided watershed included Bull Creek, a section of Bull Creek flowed in it, and Bull Creek drained out of it, the divided watershed was merged with the Bull Creek PU instead of the North Fork Little Beaver PU. In all, the coal-bearing region of Ohio was subdivided into 244 PUs with the attributes of this layer being composed of PU name and the PU number. ESRI ArcGIS 9.1 software was utilized to create the Ohio PU shapefile layer. The data frame was set to geographic coordinate system GCS_North_American_1983 and projected coordinate system NAD_1983_StatePlane_Ohio_South_FIPS_3402_Feet with the projection Lambert Conformal Conic. The DMRM will utilize this GIS layer as a basis for future data and to support AML reclamation planning efforts and ongoing maintenance of the national AMLIS database.
