Law enforcement agencies in and around Salt Lake City are asking people not to call 911 to report violations of the ban on personal fireworks this holiday weekend as Utahns celebrate the Fourth of July.

Instead, they are asked to call nonemergency dispatch numbers.

The Salt Lake City Police Department said residents of Salt Lake City and Sandy should call 801-799-3000. Other Salt Lake County residents should call the nonemergency number for the county sheriff: 801-840-4000.

The fireworks ban comes as wildfires rage across the state, 80% of which have been started by people, rather than by lightning or other natural causes.

Utah Gov. Spencer Cox announced the ban last month, granting temporary authority to the state forester to prohibit fireworks between July 2 through 5, while allowing cities and towns to designate certain areas where personal fireworks may be used.

No city in Salt Lake County has elected to allow such fireworks over the holiday weekend. Violators, law enforcement officials vowed, will be held criminally and financially liable.

Small sparklers are not included in the ban.

Traditionally, fireworks are allowed in Utah on the three days surrounding Independence Day, between 11 a.m. and 11 p.m., and around the July 24 Pioneer Day celebration, along with brief periods on New Year’s Eve and Lunar New Year. But massive wildfires around the state have changed officials’ calculations for this year.

If you see people setting off banned fireworks, Salt Lake County Mayor Jenny Wilson wrote in an op-ed for The Salt Lake Tribune, please report them.

“Our fire, search-and-rescue, and emergency management teams are already at their limits — that is not a figure of speech,” Wilson wrote. “These fires move so fast and burn incredibly hot. Crews cannot extinguish one fire and immediately race to the next. There are very real limits to our capacity. Every resource is committed, and the season is far from over. The least we can do is not add to the burden of these brave men and women.”

The county mayor noted that Utahns are already calling in about illegal fireworks, and agencies have outlined how to report them in anticipation of violations.

Wilson asked residents to “stay vigilant,” adding, “We will look back on this summer as the year we started new traditions, celebrated in new ways and sacrificed just a little for our neighbors and communities.”

July Fourth celebrations come not long after the Bonneville Fire swept through the area above the University of Utah and as the massive Cottonwood Fire continues burning near Beaver, destroying scores of structures and costing millions of dollars to fight.
