Current Data Sets • Animal operations facilities (CAFOs) • Hazardous waste generator/transporters • Hazardous waste treatment/storage/disposal sites • National pollutant discharge elimination system (NPDES) permit holders • National priority sites • Non-discharge permits • Old landfill sites/pre-regulatory sites • PCB sites Department of Environmental Quality Division of Water Resources 2
Current Data Sets • • • • • • • •
Pollution incidents Septage disposal sites Soil remediation sites Solid waste facilities Superfund sites Tier II sites Underground injection control permits Underground storage tank facilities
Department of Environmental Quality Division of Water Resources 3
Current Data Sources • State programs (DPS, DWM, DWR) • Federal agencies (EPA)
Department of Environmental Quality Division of Water Resources 4
Current Data Uses • SWAP application • Contaminant rating • Risk category • Now all are high – have capability/plans to change to higher, moderate, lower • Spillability, treatability, size • SWAP report • Online SWAP mapping tool • Development of SWP plans Department of Environmental Quality Division of Water Resources 5
Criteria for Current Data • Electronic database containing data related to contaminants of concern with statewide coverage. • Contaminants of concern include those regulated under the NC’s Drinking Water Act, the federal Safe Drinking Water Act, SARA Title III and CERCLA (superfund)
Department of Environmental Quality Division of Water Resources 6
Potential Criteria for Future Data • New statewide data coverage • Weighting potential risk of PCSs • Permit information • Compliance history • Types of contaminants • Spillable • Treatable • Quantity of materials • Surface vs. groundwater
Department of Environmental Quality Division of Water Resources 7
Potential PCSs Previously Considered • • • • • • • •
Active landfills Gas stations Chemical/petroleum processing/storage facilities Wood/pulp/paper processing and mills Furniture repair/manufacturing Parking lots/malls (>50 spaces) Road salt storage Recreational use of motorized watercraft on surface waters • Railroad yards/maintenance/fueling areas • Transportation corridors (interstate highways/railroads) Department of Environmental Quality Division of Water Resources 8
HB894 PCS Exercise Results • 9 of 16 remain higher risk rating • 5 of 16 change to moderate risk rating • 2 of 16 change to lower risk rating • Add • Chemical/petroleum processing/storage sites • Chemical/petroleum pipelines • Above ground storage tanks • Fertilizer, pesticide, and petroleum storage, distribution, handling, mixing and cleaning areas Department of Environmental Quality Division of Water Resources 9
