A former environmental and safety staff member at Johnson & Johnson’s Ortho-Clinical Diagnostics, Danielle primarily concentrates her practice on environmental law. She advises energy utilities on complex state and federal environmental laws related to the development of energy resources and operations involving electrical generation. She also counsels businesses on project development and operations as well as applicable environmental laws. Danielle’s practice involves compliance, permitting, transactional, and litigation work under various environmental statutes, with a concentration on the Clean Air Act, climate change; the Clean Water Act, especially 316(a) and (b); and environmental remediation (CERCLA).

Danielle has extensive experience handling Clean Air Act permitting and compliance at the state and federal levels, counseling clients that include energy and utility, gas-transmission and distribution, and manufacturing companies on Clean Air Act and Clean Water Act legal solutions to existing, new, and proposed regulations impacting these industries. She also assists clients with other environmental laws and regulations, including remediation issues pursuant to CERCLA and voluntary clean-up programs.

Danielle routinely represents clients in enforcement actions initiated by the NYS Department of Environmental Conservation and the US Environmental Protection Agency, particularly with regards to the Clean Air Act, including New Source Review, hazardous air pollutants, and Title V and state facility permitting. She negotiates orders on consent, represents clients in administrative proceedings and mediations, and responds to intervening parties and state and federal agencies. Danielle has also been involved in private cost-recovery actions associated with the allocation and reimbursement of remedial costs, including litigation, mediation, and participation in potentially responsible party groups.
