  2. PURPOSE  Present goal and significance  Describe approach  Solicit feedback Casmalia Wetland Mitigation Project, UCSB

  3. GOAL To provide the EPA with preliminary wetland mitigation alternatives to compensate for wetlands lost during Casmalia site clean up. Casmalia Wetland Mitigation Project, UCSB

  4. PROJECT SITE EPA carrying out long term remediation of site  Wetlands: • consist of 5 ponds • collect storm water runoff • support wetland habitat

  5. CERCLA Clean Water Act SIGNIFICANCE OF PROJECT CERCLA CERCLA Cleanup of toxic wastes Clean Water Act Endangered Species Act California’s Fish and Game Code Endangered Species Act Protection of wetlands Preservation of listed species Provide Wetland Mitigation Alternatives RESOLVE CONFLICT  FACILITATE LONG TERM REMEDIATION

  6. OBJECTIVES & APPROACH Characterize wetlands / Define Regulatory Framework Review case studies Outline potential alternatives Use criteria to evaluate alternatives Recommend alternative(s) Casmalia Wetland Mitigation Project, UCSB

  7. ARARS FEDERAL STATE Clean Water Act Endangered Species Act CA Fish & Game Regulations (5:1 Mitigation Ratio required) LOCAL REGULATORY FRAMEWORK CERCLA Site Cleanup Casmalia Wetland Mitigation Project, UCSB

  8. CHARACTERIZE SITE WETLANDS Delineate extent of wetlands Describe: • Hydrology • Geology (soils, topography) • Biological Resources (vegetation, animals) Casmalia Wetland Mitigation Project, UCSB

  9. REVIEW CASE STUDIES Similar Case Studies including: - Wetland mitigation - CERCLA cleanups - Presence of Endangered Species Vandenberg Air Force Base Guadalupe Oil Field Restoration Sweetwater Marsh Casmalia Wetland Mitigation Project, UCSB

  10. Effectiveness Geological Hydrological Biological Implementability Cost PRIMARY DEFINE CRITERIA THRESHOLD Human Health & Environment ARARS Casmalia Wetland Mitigation Project, UCSB

  11. DESCRIBE ALTERNATIVES • ALTERNATIVES • No Action • B Drainage North • B Drainage South • C Drainage • Mitigation Bank C a s m a l i a C r e e k C D r a i n a g e B D r a i n a g e N o r t h # # B D r a i n a g e S o u t h #

  12. Evaluation Matrix

  13. B DRAINAGES & C DRAINAGE MITIGATION BANK POSSIBLE RESULTS HIGHEST RANKED ALTERNATIVES WILL LIKELY BE: Casmalia Wetland Mitigation Project, UCSB

  14. UNCERTAINTIES Exact wetland delineation and size Boundaries of contaminant plume Casmalia Wetland Mitigation Project, UCSB

  15. ACCOMPLISHMENTS  Developed Understanding of Regulatory Framework Refined & Developed Criteria  Identified Comparable Case Studies  Established Required 5:1 Mitigation Ratio Casmalia Wetland Mitigation Project, UCSB
