3 NDEP - Mission Statement Protect and enhance the environment of the State of Nevada consistent with the public health and enjoyment, the propagation and protection of terrestrial and aquatic life, the operation of existing industries, the pursuit of agriculture, and economic development activities.
4 Nevada Division of Environmental Protection NDEP Bureaus1) Air Pollution Control2) Air Quality Planning3) Mining4) Water Pollution Control5) Water Quality Planning6) Waste Management7) Corrective Actions8) Federal Facilities
5 NDEP Bureau of Federal Facilities Created in 1990 to provide programmatic and regulatory oversight of federal facilities in NVIn southern NV this includes Nellis Test and Training Range, Indian Springs, and Tonopah Test RangeRepresents interests of all NDEP bureausAssists other state agencies at these facilities
6 Bureau of Federal Facilities Federal Facilities Covered Within the Death Valley GW Flow System Nevada Test Site (DOE)Tonopah Test Range (DOE)Nellis Air Force Range (DOD)Indian Springs Air Force Auxiliary Field (DOD)
7 Federal Facilities in the Death Valley GW Flow System
8 NDEP Environmental Oversight of NTS Programs FY NDEP entered into an Agreement in Principal (AIP) for environmental oversight of DOE NTS activities. This included all ongoing program activities, as well as review of all historic contaminationIn 1996 NDEP entered into the Federal Facility Agreement and Consent Order (FFACO), a formal consent order addressing actions necessary to remediate historic contamination
9 FFACOThe purpose of the FFACO is to identify sites of potential historic contamination and implement corrective actions based on public health and environmental considerationsThe FFACO outlines a process to insure that DOE thoroughly investigates and takes corrective action to mitigate the release of hazardous pollutantsCovers NTS, TTR, NAFR, CNTA, PSA
10 Background --History of Groundwater Investigations on the NTS DOE Program EvolutionHydrologic Resource Management Program (HRMP)Ground Water Characterization Program –1989 (GCP)Underground Test Area Project –1994(UGTA)
12 Environmental Investigations at NTS The FFACO includes provisions for:Soils InvestigationsIndustrial SitesUnderground Test Area (UGTA)Offsites – Central NV Test Area, Project Shoal
13 NRS 445a.415 - “Waters of the State” “Waters of the state” means all waters situated wholly or partly within or bordering upon this state, including but not limited to:All streams, lakes, ponds, impounding reservoirs, marshes, water courses, waterways, wells, springs, irrigation systems, and drainage systems, and all bodies or accumulations of water, surface and underground, natural or artificial.
15 NRS 445a.465 - Protection of Waters of the State Except as authorized by a permit …, it is unlawful for any person to:1. Discharge from any point source any pollutant into any waters of the State or any treatment works.2. Inject fluids through a well into any waters of the State.
16 NRS 445a.465 - Protection of Waters of the State, cont. Except as authorized by a permit …, it is unlawful for any person to:3. Discharge from a point source a pollutant or inject fluids through a well that could be carried into the water of the State by any means.4. Allow a pollutant discharged from a point source or fluids injected through a well to remain in a place where the pollutant or fluids could be carried into the waters of the state by any means.
17 Corrective Action Authority NDEP’s Authority Comes From:NRS and NACClean Water ActAgreement in Principle between State, NNSA, and DODFederal Facilities Agreement and Consent OrderEnvironmental Permits
18 UnderGround Test Area Project Investigate nuclear testing effects on groundwater at the Nevada Test Site Identify risks resulting from underground nuclear testing Predict groundwater movement of contaminated groundwater Determine whether radionuclides have moved appreciable distances Define boundaries for safe water use and establish long-term monitoring network
21 The UGTA Corrective Action Strategy Corrective Action Investigation PlanCorrective Action InvestigationCorrective Action Decision DocumentCorrective Action PlanClosureLong Term Monitoring
22 Define / Negotiate CAU Boundaries Contaminant Boundary(model-predicted perimeter)Defines the extent of radionuclide-contaminated groundwater from underground testing exceeding the Safe Drinking Water Act (SDWA) standardsComposed of both a perimeter boundary and a lower hydrostratigraphic unit boundaryThe computer model predicts the location of this boundary within 1,000 years and must do so at a 95% level of confidence
23 Define / Negotiate CAU Boundaries (continued) Compliance Boundary(Regulatory Perimeter)From the contaminant boundary predicted by the computer model, a compliance boundary will be negotiated between NDEP and DOEThe compliance boundary will define the area within which the radiological contaminants above the SDWA standards relative to background are to remain
24 Define / Negotiate CAU Boundaries (continued) The compliance boundary may or may not coincide with the contaminant boundaryIf the predicted location of the contaminant boundary cannot be accepted as the compliance boundary, an alternate compliance boundary will be negotiated by both parties
25 Containment Control or Long Term Monitoring? If containment control will be required then DOE develops contaminant control Corrective Action Plan (CAP)If Long-Term Monitoring is sufficient for CAU surveillance, then DOE develops monitoring CAPNDEP approval is required before proceeding to 5 year Proof of Concept Monitoring
26 Five Year Proof of Concept (applies to both containment control & LTM) If long term monitoring is required:Groundwater wells in the monitoring network determine if the network design provides adequate CAU surveillanceMeasurements of field parameters will be used to demonstrate if model is capable of making reasonable predictions that fall within an acceptable level of confidence
27 Long Term Closure Monitoring NDEP Approval of Closure Report required before proceeding to Long Term Closure MonitoringDOE performs long-term monitoring in accordance with a Closure ReportNDEP reviews periodic monitoring results, verifies that the monitoring provisions in the Closure Report are followed, and ensures that contamination remains contained
28 NDEP’s Objectives Protect the Waters of the State Ensure contaminants are acceptably contained and that further degradation of Nevada’s water resources is preventedMake available as much of the water resource for future regional growth and development as reasonably practical
29 Growth Continues … Source: Acevedo et al., USGS This slide could be cut out
30 … and so will the Demand for Water! Use this slide to talk about growth and development as related to future water needs in Southern NV
31 NDEP’s NeedsKnowledge and understanding of the regional, NTS-scale, and CAU-scale hydrogeologic setting and phenomenaAbility to monitor and predict the migration of contaminants, and demonstrate acceptable containmentAbility to estimate the impact of current and future regional water usage
32 NDEP’s Goals and Vision Produce robust models of contaminant transport, which can be used as tools for water resource protection and development as demands on the resource change over timeAgree on compliance boundaries that are both technically supported and administratively reasonable
