Representative Experience

Environmental Litigation

• Represents a manufacturer of PFOS/PFAS products in multiple cases currently residing in a multidistrict litigation ("MDL") proceeding in Charleston, South Carolina. The plaintiffs allege toxic tort claims in some of the actions and environmental cost recovery claims in other actions.
• Represented a major City in a federal CERCLA lawsuit and an administrative proceeding before the Regional Water Quality Control Board ("Board") concerning contaminated sediment in the shipyard area of the bay. This representation included a collaborative mediation process with the Regional Water Quality Control Board over the course of two and a half years to mutually develop a cost-effective cleanup methodology and plan to protect the beneficial uses of the bay. In addition, Ledger served as lead trial counsel in a high-profile two-week administrative trial before the Board, in which we convinced the Board to include several additional PRPs, effectively significantly reducing the remediation costs to the City.
• Represented a petroleum company in multiple MTBE litigation matters concerning alleged contamination of drinking water aquifers throughout the State of California and an MDL proceeding in New York. Following the federal district court’s favorable summary judgment ruling rejecting the plaintiffs' commingled product causation theory, the remainder of the cases were dismissed for a waiver of costs.
• Represented an environmental consulting company in a property damage and personal injury action filed by numerous plaintiffs in Ventura, California. The environmental consultant had conducted environmental assessment work for the County of Ventura on and surrounding the plaintiffs’ parcels. A very favorable settlement was achieved based on our arguments that no duty is owed to third parties when the work conducted is limited to environmental investigation and does not include environmental remediation.
• Represented a city in northern California in a cost recovery case filed by a redevelopment agency for creosote and petroleum hydrocarbon contamination of the port area. We were able to convince the plaintiff to have its expert consultants work with consultants retained by GRSM to agree on much more cost-efficient remediation options developed by GRSM's consultants and attorneys, which were ultimately accepted by the Regional Water Quality Control Board. The result was a very favorable settlement.
• Represented real estate developers in a CERCLA cost recovery case filed by a metals producer for soil and groundwater contamination in El Segundo, California. We were able to effectively work with its consultants and with the plaintiff and its consultants to convince the Regional Water Quality Control Board to not order a groundwater remediation and instead require only monitoring as long as the data generated demonstrates no migration and no threat to any drinking water aquifers.
• Represented an environmental consulting firm in an action filed by several environmental public interest groups alleging numerous violations of federal environmental statutes and regulations focused on the alleged improper handling, storage, treatment, and disposal of dioxin-containing hazardous waste. The primary issue was the interpretation of RCRA regulations as pertains to environmental consultants. We filed a motion for summary judgment attacking plaintiffs' interpretations, and, prior to filing an opposition, the plaintiffs agreed to dismiss our client for a waiver of costs.
• Represented a dry cleaning equipment manufacturer in a CERCLA cost recovery action for the costs of remediating soil and groundwater contamination caused by dry-cleaning operations. We were able to convince the Regional Water Quality Control Board to accept a bioremediation option for the groundwater contamination, which substantially reduced the value of the plaintiff's claims, resulting in a very favorable settlement.
• Represented a metals manufacturing company in the defense of a CERCLA action filed by the Housing Authority of a major city for primarily lead and PCB contamination.
• Represented a pesticide formulation company in a CERCLA action prosecuted by the United States EPA and the California DTSC.

The jury returned a defense verdict.

• Represented a strawberry producer in defense of the plaintiff's claimed birth defects from his mother's alleged exposure to agricultural chemicals while working in strawberry fields. Ledger was lead trial counsel in a 10-week jury trial with multiple international expert witnesses, including complex air modeling opinions from all parties and multiple days of hearings concerning foundational arguments to those expert witnesses’ air modeling opinions. The jury returned a defense verdict.
• Represented product manufacturers, distributors, and retailers in over 75 cases in over 25 years involving benzene exposure allegations.
• Represented two clients in the FEMA trailer litigation in a federal MDL proceeding in New Orleans, which is comprised of several hundred plaintiffs alleging injuries from formaldehyde exposure from trailers provided by FEMA following Hurricane Katrina.

• Lead trial counsel for three defendants in a matter filed by multiple plaintiffs involving Proposition 65 and common law claims concerning environmental exposures to petroleum coke dust surrounding a petroleum coke and coal storage facility in San Pedro, California. A three-week bench trial to determine if the plaintiffs had sufficient expert support to establish environmental exposures under Proposition 65 ended with a defense verdict in our favor, which led to a dismissal of all other claims for a waiver of costs.

The jury returned a defense verdict.
