Boulder will begin enforcement of its bear-resistant trash container ordinance on Oct. 1.

Boulder officials announced Friday that enforcement will begin in the first implementation zone, located west of Broadway, south of Hawthorn Avenue and north of Dartmouth Avenue. All trash and compost containers, including dumpsters and enclosures for waste, must meet specific bear-resistant requirements. 

Recycling containers do not need to be bear-resistant.

The goal of the ordinance is to reduce the food supply that draws bears to town and reduce bear deaths. The ordinance was adopted after four bears were killed in Boulder in 2013.

Western Disposal is in the process of replacing its customers' containers with a bear-resistant retrofit.

The ordinance will apply to all properties west of Broadway and south of Sumac Avenue in 2015. The specific enforcement dates will be determined once Western Disposal and other haulers tell the city how quickly they can provide bear-resistant containers to those homes.

The fine for not having a bear-resistant container is $250 for a first offense, $500 for a second offense and $1,000 for a third offense. If someone can demonstrate that they ordered a bear-resistant container before the enforcement date, they will not be fined.
