Enforcement

NHDES reviews referrals for potential air-related violations and determines if an enforcement action is warranted.

The NHDES Air Enforcement Program is committed to consistent, predictable and appropriate enforcement activities that are protective of public health and the environment, while creating a credible deterrent against future violations. NHDES focuses on violations by stationary sources, such as power plants and manufacturing facilities; improper management of asbestos; and open burning of nonconforming materials. NHDES encourages early identification and correction of environmental violations in order to minimize impacts to public health and the environment. Once a violation is referred to the Program, the Program reviews the circumstances of the violation and issues or recommends an appropriate enforcement response that will achieve compliance with applicable environmental laws and a lower incidence of repeat violations.
