From the Provided Letter: "The Colorado Division of Oil and Public Safety (Division) has been receiving complaints from consumers of propane throughout the state that their propane provider is unable to provide timely service of propane deliveries during the extreme cold conditions that the state is currently experiencing. In some cases this inability of the propane provider to service their customers has resulted in out of propane conditions with the potential of damage to property due to freezing of water pipes, and more importantly life safety concerns, with these consumers using space heaters, or even attaching their systems to other containers (e.g. 100lb cylinders) without a proper test for leakage due to an interruption of service. Because of these issues, and the health and safety concerns they bring in this current 2023/2024 winter heating season, the Division will not enforce the provisions of Colorado Revised Statute 8-20-302 Refill Container Unlawful (which prohibits filling propane container owned by others)."
