My work is to update, identify and corroborate which DOE facilities are located within the M4S areas in order to reduce potential discharge of pollutants to separate stormwater system following the requirements stipulated by the Environmental Concervation Law of the New York State and the Clean Water Act. Schools located nearby water bodies or indirect drainage areas wich runoff can fall into state water must be evaluated as well. The identification of facilities in these areas is one part of the job. Consolidating a geodatabase of facilities is one GIS task. But in addition to this, is necessary to verify which schools are closed from MS4 and waterbodies being a potential risk for stormwater quality. Verification and review of stormwater system city plans and catch basin by fieldwork is another responsibility. During the internship, I have to georeferencing and digitalizing catch basins per facility, so the data is included in DOE’s Geographic Information System
