It is unlawful to discharge any common fireworks on any public property or Right of Way. They may be used on private property with that property owners permission.

ORCAA acknowledges that fireworks are a source of air pollution, but does not advocate a ban on the devices. Rather, ORCAA seeks to ensure people are aware of the potential health risk posed by exposure to the pollution from these devices.

To minimize impacts from fireworks pollution, individuals should reduce or eliminate their use of personal fireworks ­– these tend to concentrate their smoke near ground level. Instead, residents may attend community-sponsored aerial fireworks displays. These create pollution as well, but generally much higher above the ground where it can dissipate more completely before reaching people at ground level.

Folks who do set up fireworks on their own should keep the devices well clear of buildings and combustible materials (including vegetation). Besides the health risks from the air emissions of fireworks, the devices also pose serious fire-safety risks. They must also be careful when disposing of the debris afterwards. After dousing the paper and plastic with water (to reduce risks of fire), the waste material should be disposed of with your garbage. The waste should never be burned – not only does state law prohibit burning the material, but the colorful wrappings contain chemicals that could release additional dangerous toxics into the air if burned.
