Casmalia Wetland Mitigation Group Project Emily Bosanquet  Todd Cooper Ann Hayden  Vicky Krikelas  Michelle Torrent Faculty Advisors: Professor Trish Holden  Professor Mike McGinnis

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

GOAL 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

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

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

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

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

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

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

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