Krista has broad experience in Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and California Hazardous Substance Account Act (HSAA) litigation, multi-party allocation and cost recovery proceedings, natural resource damages claims, and contaminated site cleanup, often involving parallel agency enforcement, where she is skilled at developing integrated strategies to maximize outcomes in both actions.

Krista also assists clients with regulatory approvals, compliance, and risk mitigation under federal and state environmental laws, including Department of Energy and California Energy Commission regulations, California Air Resources Board regulations, Federal Trade Commission Green Guides, hazardous waste management regulation, and climate disclosure laws. She has defended and negotiated favorable settlements for clients in enforcement actions brought by the Environmental Protection Agency, California Air Resources Board, California Energy Commission, and California Regional Water Quality Control Boards.
