The Cedar Hill City Council passed Ordinance 2002-127 on November 12, 2002, effective immediately, which prohibits all outdoor open burning except for approved TNRCC commercial trench sites. Commercial trench sites approved by TNRCC must also have a permit issued by the Fire Marshall's Office, which may include further restrictions. This does not prohibit campfires in an approved fire-ring (state park), barbeque grills, masonry patio grills, chimeras, etc.
