Halloran & Sage attorneys served as lead joint defense counsel for the general waste stream defendants and co-defense counsel for the municipal defendants in the private cost recovery trial of the two most notorious Superfund sites in the state, the Beacon Heights and Laurel Park landfills. During the course of the trial and in further proceedings before the Federal District Court, we became lead counsel for all 20+ municipalities involved in this litigation. The trial, which spanned six months, involved presenting novel cost-allocation models for the apportionment of the clean-up costs among all parties. Our representation included numerous appeals to the Second Circuit Court of Appeals and relitigating certain unique issues upon remand, such as the calculation of pre-judgment and post-judgment interest under CERCLA and the effect of deposits made to the federal court registry on the calculation of interest. Our involvement in this case gave us unparalleled experience in municipal commercial and industrial liability issues arising under federal and state law relating to municipal solid waste, landfill operation and closure and Superfund liability.
