Ms. Sanford has advised clients in connection with natural resource damage claims by state and federal trustees and the availability of Great Lakes Legacy Act funding for watercourse remediation projects. Ms. Sanford also has counseled clients regarding corporate officer and director liability in the environmental context as well as corporate shareholder liability. She has defended companies in cost recovery actions brought by federal and state governments and has advised clients on appropriate responses to unilateral cleanup orders issued by EPA. Ms. Sanford has represented companies in private cost recovery actions and negotiated numerous agreements with other potentially responsible parties and with EPA and state agencies. She also has counseled clients regarding compliance with the Consumer Product Safety Improvement Act, TSCA, FIFRA, and the California Safer Consumer Products regulations.
