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