In addition , GIS was used in conjunction with data <br /> in Microsoft Excel spreadsheets to support assigning f� <br /> restoration priorities for each AMD discharge . Based <br /> on the scoring and prioritization process , a structure <br /> for listing the discharges in an organized fashion — <br /> was developed . Discharges were prioritized , based <br /> on the overall goal of reducing AMD pollution . <br /> More subjective criteria influenced the order of <br /> restoration within the individual subwatersheds . <br /> Based on the analysis of all AMD nonpoint pollution - 4 <br /> data , a top-down (i . e . , upstream to downstream ) �. <br /> watershed /subwafershed restoration approach <br /> was recommended . In addition to mine discharges, the <br /> ' Specific objectives achieved through the successful assessment was a tool for improving <br /> water quality by reducing the impacts <br /> completion of the plan : of agricultural nonpoint pollution <br /> • Compiled a GIS-based inventory of the sources. <br /> a most significant nonpoint source water <br /> pollution in the watershed <br /> • Developed a GIS capable of compiling relevant information ( past , present, and <br /> future) <br /> • Prioritized and ranked subwatersheds based on the impact of AMD loadings and <br /> its effect on the mainstream of the Casselman River <br /> Prioritized and ranked the most severe AMD discharges in the watershed <br /> • Developed a restoration plan that described the type , costs, and <br /> recommendations for remediating the most severe discharges <br /> • Prioritized and ranked the subwafersheds based on agricultural nonpoint source <br /> u water pollution . <br /> • Prioritized and ranked subwatersheds based on both AMD and agriculture <br /> nonpoint source pollution <br /> • Developed a comprehensive water quality and quantity and agricultural <br /> screening sampling program <br /> Although the restoration plan was completed in fall 2003 , it has led to immediate <br /> remediation efforts . Based on project recommendations highlighted in the plan , Somerset <br /> Conservation District is currently finalizing the design of an AMD treatment project for Coal <br /> Run , ranked as the third highest contributor of AMD loadings , and has also applied for <br /> funding to design and construct treatment systems on Shaw Mine Run , ranked as the second <br /> highest contributor of AMD loadings . <br /> The project is realistic and targeted and has exceeded its intended objectives . It is currently <br /> being implemented , and its success is evident in the watershed . Somerset Conservation <br /> District is scheduled to begin collecting detailed agricultural operations information from <br /> farms located in the high-priority watersheds identified in the plan . The district can efficiently <br /> target sites with high runoff potential and is moving toward adopting best management <br /> practices for agriculture in these watersheds . <br /> *Case Study courtesy of ESRI ArcUser Magazine . <br /> ePublic Services <br /> Many of the Department ' s divisions provide services to the public, both as programs and <br /> projects that are aimed at improving the social and environmental conditions of the County . <br /> 122 <br /> GIS Needs Assessment and Implementation Plan Chapter I - Departmental GIS Needs Assessment <br />
