Paperwork and some regulation hurdles are slowing the process for the sale of fireworks. The legal sale of consumer pyrotechnics went into effect in Iowa Thursday, but acquiring state licenses for vendors to sell fireworks has been another issue. An online portal started taking applications Thursday, but was quickly overwhelmed with hits. More information can be found on the Iowa Department of Public Safety website. People are reminded that the new Iowa law authorizes the sale of fireworks, but the display of fireworks is controlled by local jurisdictions.
