Exempt Auctioneers Charitable Solicitation Requirements

As defined in the 'Colorado Charitable Solicitations Act', a 'paid solicitor' is a person that, for monetary compensation, performs a service in which contributions are solicited in Colorado for a charitable purpose or for the benefit of a charitable organization.     The act excludes from the definition of 'paid solicitor' an auctioneer who provides auctioneer services to a charitable organization. As a result, the auctioneer is exempted from the requirements of the 'Colorado Charitable Solicitations Act' for paid solicitors. The exemption applies regardless of whether the auctioneer is contracted or paid to provide their auctioneer services to the charitable organization or is volunteering their auctioneer services to the charitable organization without compensation. However, for the exemption to apply, an auctioneer who provides auctioneer services to a charitable organization may not directly receive or handle contributions or charitable funding on behalf of the charitable organization for which the auctioneer is contracted or volunteering.(Note: This summary applies to this bill as enacted.)

Diseased Livestock Indemnity Fund

Previously, money in the diseased livestock indemnity fund could be used only to pay indemnity to a livestock owner whose herd had been sold for slaughter or destroyed because the herd was exposed to or diagnosed with an infectious or contagious disease. The act expands the permissible uses of the money in the diseased livestock indemnity fund by allowing the commissioner of agriculture to authorize using the money to prepare for and respond to certain emerging threats to livestock health.     The act renames the fund the 'livestock health preparedness, response, and diseased livestock indemnity fund' to reflect the expanded scope of the permissible uses of money in the fund.(Note: This summary applies to this bill as enacted.)

Water Projects Eligibility Lists

Maddy summaryThis bill approves specific updates to eligibility lists for two Colorado water funding programs. It adds new drinking water projects (like Delta County's distribution system) and modifies existing entries (such as adding "green infrastructure" to Loveland's project), while deleting completed projects (like Kiowa's). These changes determine which local water districts, municipalities, and property associations can access financial assistance from the Drinking Water Revolving Fund and Water Pollution Control Revolving Fund. The bill does not create new funding rules but formally adopts the Commission's proposed list adjustments.
