Workers' Compensation Benefits Proof of Entitlement

The act requires an employer or the employer's insurer to use the division of workers' compensation's (division) utilization standards when responding to a request for authorization from a treating physician, and, if they do not, the director of the division may deem the services as authorized, reasonable, and necessary and require payment for the services by the employer or the employer's insurer. The act provides injured workers control over the selection of their primary treating physician in workers' compensation cases, allowing them to choose from any level I or level II accredited physician through the division subject to geographic limitations. The act creates the mechanism by which an injured worker may select the treating physician and requires the employer or insurer to choose the physician when an injured worker is unable or unwilling to select the treating physician.

Railroad Safety Requirements

The act requires that, immediately after a railroad notifies the state's watch center in the department of public safety (watch center) of an emergency involving a train, the watch center must notify the public utilities commission (commission) and the office of rail safety (office) of the incident. The commission is required to submit a report to specified committees of the general assembly on the information reported by railroads regarding an emergency involving a train. A crew member of a train operated by a railroad may communicate with first responders during an emergency situation after notifying the railroad dispatch. A crew member has discretion in determining the appropriate response to the emergency situation, including cutting the railroad crossing. A railroad employee or a crew member is immune from civil liability and is not liable in civil damages for actions taken in good faith in the course of a response to an emergency situation involving a train. The act eliminates the shared authority that the commission, the department of public safety, and the department of transportation had to inspect and investigate railroads and grants the commission alone the authority to engage in inspection, investigation, and enforcement activities regarding the following railroads: A class I railroad; A railroad operating on any line that was used by class I railroads as of July 1, 2024; and A passenger railroad. The act requires the office to gather, analyze, and assess information, including: Data to create a more comprehensive understanding of railroad safety; Wayside detector information; Information regarding blocked public crossing locations; Information regarding railroad maintenance activity; An assessment of the state's ability to respond to a large-scale release of hazardous materials from railroad transportation; The best practices for ensuring financial responsibility for response, cleanup, and damages from major rail events, including reviewing best practices from other states; and Communication issues impacting railroad lines in the state. Beginning on or before July 1, 2027, a railroad regulated by the commission is required to pay a fee to cover the costs incurred by the commission and the office in relation to the act. The commission shall determine a methodology for calculating the fee by rule, and the commission may include specified criteria in the calculation. The total amount collected pursuant to the annual fee must not exceed $2,900,000 in a calendar year. A railroad regulated by the commission must pay the fee in equal quarterly installments and is subject to penalties and interest if they fail to timely pay the fee.

Section 4 creates a new community investment portfolio (portfolio) within the public school fund, and requires the state treasurer to invest at least 20% of the public school fund's value into the community investment portfolio by July 1, 2032. Money in the portfolio must be invested in community investments, and allowable community investments include: Bonds issued by Colorado school districts and charter schools; Certificates of participation issued by Colorado school districts and charter schools; Mortgage pass-through securities and collateralized mortgage obligations secured by residential real estate, the majority of which is owned by public school employees; Loans to the Colorado middle income housing authority for a revolving loan fund that funds rental housing developments that include preferences for public school employees; Bonds issued by the middle income housing authority that fund rental housing developments which include preferences for public school employees; Bonds or mortgage-backed securities issued by the Colorado housing and finance authority that fund rental housing developments that include preferences for public school employees or mortgages secured by residential real estate, the majority of which is owned by public school employees; Mortgage revenue bonds that support public school employee mortgages with interest rates of 3% or less; Loans to community development financial institutions or nonprofits with a history of providing affordable home ownership financing that fund: Housing that includes preferences for public school employees; or Low-interest mortgages secured by residential real estate that is owned by public school employees; Down payment shared appreciation products secured by residential real estate that is owned by public school employees; and Other investments that support public purpose of the portfolio.

Subject to a specified limitation, the treasurer shall invest the following amounts in the program by the following dates: By July 1, 2028, the greater of 6% of the fund's value or $100 million; and By July 1, 2030, the greater of 12% of the fund's value or $200 million. The treasurer shall aim to invest a target of 75% of the money in the program into the shared equity down payment assistance program for public school employees. The shared equity down payment assistance program must be established by July 1, 2026. Once the shared equity down payment assistance program is established: The public school fund investment board shall purchase from the program manager the mortgage products created through the shared equity down payment assistance program; and The public school investment board may provide notice of any discontinuation of future investments that the program manager has not already committed to the shared equity down payment assistance program, which notice must be provided at least 6 months prior to discontinuation. The treasurer shall aim to invest a target of 25% of the money in the program into allowable community investments. The program manager shall establish underwriting criteria and other guidelines for the shared equity down payment assistance program so that the shared equity down payment assistance program: Prioritizes first-time home buyers that use the home as a primary residence; Provides shared equity down payment assistance to public school employees and aims to help as many public school employees as possible achieve affordable home ownership; and Allows appreciation-sharing between the shared equity down payment assistance program and the borrower. Unless investments in the shared equity down payment assistance program have been discontinued and there is no fund money invested in the shared equity down payment assistance program, the program administrator shall present an annual report to the board on program outcomes. For the 2025-26 state fiscal year, section 5 appropriates $375,900 from interest or income earned on the investment of the money in the public school fund to the department of the treasury.

Regulating Apprentices in Licensed Trades

Starting January 1, 2027, the act prohibits an electrical employer or plumbing employer that employs an apprentice in the state (employer) from registering an apprentice with the employer's respective governing board (board) unless the apprentice is enrolled in an apprenticeship program training the apprentice for an occupation officially recognized by the United States department of labor as an electrical occupation for an electrical apprenticeship or a plumbing occupation for a plumbing apprenticeship.

If the board cannot verify that an apprentice is eligible to be registered as an apprentice within 60 days after notice of noncompliance, the board shall remove the apprentice's registration with the board, and the noncompliant apprentice shall not perform work as a plumbing or electrical apprentice in the state.
