Danielle focuses her practice in the area of 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, and counsels businesses on project development and operations, and applicable environmental laws. Her practice involves compliance, permitting, transactional and litigation work under various environmental statutes, with a concentration in the Clean Air Act, climate change, 316(a) and (b) of the Clean Water Act and environmental remediation (CERCLA).

Danielle has extensive experience with Clean Air Act permitting, compliance and the regulatory process implementing the Clean Air Act at both the state and federal level. Danielle has counseled clients including 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. Danielle has also assisted clients with creative and effective solutions to issues associated with environmental remediation pursuant to CERCLA and voluntary cleanup programs.

Danielle has significant experience with representing clients in enforcement actions initiated by the New York State Environmental Conservation and the United States Environmental Protection Agency, particularly in the area of the Clean Air Act including New Source Review, hazardous air pollutants and Title V and State Facility permitting. This experience includes negotiating orders on consent, representing clients in administrative proceedings and mediations, and responding to intervening parties and state and federal agencies. Danielle has also been involved in a number of private cost recovery actions associated with the allocation and/or reimbursement of remedial costs, including litigation, mediation and participation in potentially responsible party groups.

Danielle’s background allows her to understand the technological aspects of many environmental issues and associated laws and regulations, resulting in a deep understanding of complex environmental laws and the ability to communicate effectively with regulators. Before attending law school and receiving a Master’s in Environmental Law, Danielle received her B.S. in Environmental Management from Rochester Institute of Technology and handled environmental compliance matters as a member of the environmental staff at Ortho-Clinical Diagnostics (a Johnson & Johnson Company).

Danielle is an active member of the firm's Women's Forum, which assists in creating opportunities for personal and professional growth among women in the firm and throughout the community.

Representative Experience

  • Represented a utility in the renewal of the State Pollution Discharge Elimination System ("SPDES") permit for the electric generating facility. The main issue is Best Technology Available ("BTA") for cooling water intake structures required by 316(b) of the Clean Water Act and 6 NYCRR 704.5. 
  • Developed a New Source Review program for a Long Island electric generating facility in order to ensure compliance with the Clean Air Act's New Source Review Requirements. 
  • Served as counsel on the renewal of the Title V (Clean Air Act) permit for a combined cycle electric generating turbine. The renewal included, among other things, negotiation of terms with NYSDEC related to emissions associated with the startup and shut down of the unit. We were successful in obtaining flexible limits in order to reduce the risk of non-compliance and enforcement actions associated with such. Previous to the revisions, the facility risked non-compliance and potential citizen suits.
