This legislation establishes the Supporting Blue Envelope Programs Act , authorizing the Attorney General, through the Bureau of Justice Assistance, to award grants to eligible entities. These grants will fund the creation or support of blue envelope programs , which are designed to enhance interactions between law enforcement and individuals with autism spectrum disorder or developmental, cognitive, sensory, or communication disabilities. The programs provide training for officers and offer communication tools, such as blue envelopes for essential documents and other accessories like car decals or lanyards, to individuals who may face communication barriers during encounters. Grant priority will be given to programs demonstrating scalability, strong community support, and involvement from multiple law enforcement agencies, particularly those with experience in person-centered and trauma-informed practices. The Director is also tasked with ensuring broad geographic distribution of awards, including to underserved rural and tribal communities. The bill mandates regular reports to Congress on program implementation and best practices, and requires the maintenance of a publicly accessible online directory of funded programs. Congress authorizes an appropriation of $5,000,000 for each of fiscal years 2027 through 2031 to carry out this section.
