DTSC Site Mitigation Program’s Mission

“To protect California’s people and environment from harmful effects of toxic substances by restoring contaminated resources”

DTSC Site Mitigation Program’s Vision

Californians enjoy a clean and healthy environment, and as a result of our efforts

• Communities are confident that we protect them from toxic

harm

• Businesses are confident that we engage them with

consistency and integrity

Site Mitigation Federal Program

• 1970s - Concerns for health impacts from uncontrolled

hazardous waste disposal sites

• 1980 - Comprehensive Environmental Response,

Compensation, and Liability Act (Federal Superfund Law) passed, gave United States Environmental Protection Agency (U.S. EPA) authority to: – Order responsible parties to clean up sites – Use federal funds at sites with no responsible parties

Site Mitigation State Program

• 1981 - California Hazardous Substance Account Act (Health & Safety Code

Division 20 Chapter 6.8) – State authority to order responsible parties to clean up sites – Provide matching state funds for cleaning up National Priorities List sites

• State program established in 1981 to address uncontrolled hazardous

substance release sites

• Department of Health Services Toxic Substances Control Division given

responsibility for program

• Started in Sacramento headquarters and expanded to other offices in

Northern and Southern California

Site Mitigation Program in 1980s

• Hazardous Substances Cleanup Bond passed in 1984 – funding at

$100 million fully expended

• State site list grew from 60 to > 400 (1983-1990)
• Started with staff < 10 in 1981

– First operated from small office in Sacramento – Managed by Sacramento, Emeryville, Long Beach, and Burbank

• ffices in 1990

Site Mitigation Program in 1990s

• Department of Toxic Substances Control

(DTSC) and California Environmental Protection Agency (Cal/EPA) formed in 1991

• Established Site Mitigation Program in 1993
• Office of Military Facilities formed in 1994
• Schools Program established in 1999

Site Mitigation Program in 2000s

• Site Mitigation Program Expanded

– Cleanup Loans and Environmental Assistance to Neighborhoods (CLEAN) Loan Program established in 2000. DTSC issued 5 loans totaling more than $3.3

• million. The existing statute mandates participation of entities that no longer
• exist. DTSC cannot issue new loans until statutory changes are made to

abolish the obsolete committee. – California Land Reuse and Revitalization Act (CLRRA) passed in 2004 – Revolving Loan Fund Program funded by U.S. EPA in 2006 – approved over $5 million in 6 loans and over $5.6 million on 22 subgrants since inception

• Reorganized into “One Cleanup Program” in 2008

– Incorporated corrective action program and Human & Ecological Risk Office

• Cleanup sites grew from 60 in 1983 to >1,600

• Hazardous Waste Control Law (Health & Safety Code Division 20

Chapter 6.5)

– Regulates facilities that treat, store, and dispose of hazardous waste – Corrective action to address hazardous waste releases – Permits for treatment, disposal, > 90 day storage – Requirements for closing permitted units and post closure – Consistent with federal hazardous waste management requirements

Site Mitigation Authorities (cont.)

– Nuclear materials regulated by federal law

• DTSC does not have authority to make zoning decisions

– We coordinate with local land use authorities to ensure that sites are cleaned to meet current and reasonably foreseeable future land use needs.

Enforcement Mechanisms

• State Superfund sites

– Imminent/substantial endangerment determination and

• rder

– Remedial action order or consent agreement

• Hazardous waste facilities

– Corrective action order or consent agreement

• Federal facilities

– Federal facility agreement (National Priorities List and State Lead sites) – Memoranda of agreement with DOD and DOE – Administrative Orders on Consent

Other Tools

• School sites

– Environmental oversight agreement – School cleanup agreement
