The intentional release of hydrocarbons into the atmosphere from a live-fire exercise may be prohibited by local open-burning ordinances. These ordinances are typically established to regulate outdoor burning activities in an effort to protect air quality and public health. They often set specific restrictions on what materials can be burned, the conditions under which burning is allowed, and the permits required for such activities. Since hydrocarbons can contribute to air pollution and pose risks to the environment and human health, open-burning ordinances are crucial for managing the impacts of such activities.

While fire safety regulations, environmental protection laws, and occupational safety guidelines are essential components of overall safety and environmental management, they do not specifically address the act of open burning in the same direct way that open-burning ordinances do. Fire safety regulations typically focus on preventing fires and ensuring safe fire practices during training or exercises. Environmental protection laws cover a broader scope of environmental impacts, while occupational safety guidelines are more concerned with the health and safety of workers involved in activities. Therefore, the most relevant regulation regarding the intentional release of hydrocarbons in this context is indeed found in open-burning ordinances.
