The Colorado Uniform Regulation of Livestock Operations Initiative, also known as Initiative 13, was on the November 3, 1998 ballot in Colorado as an initiated constitutional amendment, where it was defeated. The measure would have required uniform application of laws to livestock operations and mandated that laws and regulations concerning livestock operations be based upon the similarity in the potential impact on the environment of the livestock operation. It also would have allowed for distinctions in regulations based upon the type of animal confinement and number of livestock in an operation.
