Danielle M. Hazeltine

Senior Attorney

Danielle M. Hazeltine is a Senior Attorney in Clark Hill's Environment, Energy and Natural Resources practice group. Danielle has over fifteen years of environmental experience, with at least eleven years focused on Clean Air Act (CAA) issues. Having worked as both a private practice attorney and a regulator, she brings a unique perspective to her practice.

In private practice, Danielle has worked on a variety of environmental issues but has specialized in assisting clients to prepare applications to obtain air quality permits and permit revisions (including Title V operating permits, Nonattainment New Source Review [NSR], and Prevention of Significant Deterioration [PSD] permits) and preparing and reviewing any other documents required by the permit (compliance reports, plans, etc.). She helps clients to understand and effectively manage their compliance obligations, including compliance certification requirements, and, if problems arise, how to take appropriate corrective action, prepare the proper notifications to the agency, and negotiate settlement agreements. She frequently advises clients on regulatory requirements, including New Source Performance Standards (NSPS), National Emission Standards for Hazardous Air Pollutant Standards (NESHAP), and asbestos issues. Danielle’s main objective is to aid industrial facilities in achieving compliance with environmental regulations at a reasonable cost while maintaining optimum operational flexibility.

Before working in the private sector, Danielle worked for the Arizona Department of Environmental Quality (ADEQ), where she provided legal advice to executive management, interpreted and drafted statutes, rules, case law, and policy documents, and drafted CAA State Implementation Plans (SIPs), agency guidance documents, comment letters, and correspondence. Notably, she worked with agricultural stakeholders to develop agricultural and animal operations best management practices rules to help reduce particulate matter emissions in nonattainment areas throughout the State. She has also worked at the Arizona Department of Real Estate (ADRE), where she oversaw both the Auditing and Investigations Division and the Enforcement and Compliance Division, prepared consent orders, and negotiated settlement agreements.

Danielle currently serves as Program Chair for State Bar of Arizona’s Environmental and Natural Resources Law Executive Committee and is a member of the National Center for Homeopathy Public Policy Committee.
