On 25 September the Colorado Department of Public Health and Environment (CDPHE) recommended to amend its existing VOC rule to align with the 2018 "Phase V" Ozone Transportation Commission (OTC) regulation. This more stringent model, whose standards were only recently passed in California, has not been adopted by any other U.S. state. Colorado air regulators put forward rigorous volatile organic compound (VOC) requirements for consumer products. By adopting the rule, the state’s limits for these goods would be strictest apart from California. 

Colorado's existing VOC rule, Regulation No. 21, conforms to the Ozone Transportation Commission's 2012 'Phase IV' model rule. To reduce ground level ozone, which is the main constituent in smog pollution, and to develop draft rules for locals, the coalition of north-eastern states in the US (i.e., OTC) is collaborating to find a solution. For a variety of goods, including carpet cleaners, dusters, odour removers, insect repellants, and glass and tyre cleaners, the proposed update includes revised definitions and new or reduced VOC limits. It does not, however, contain all phase V model rule requirements. Because of freezing and safety issues, it omits new VOC criteria for windshield water repellent as well as for some lubricants that have restrictions on reformulation. 

Additionally, the proposal forgoes stricter regulations on some aerosols due to propellant concerns. The proposed rule mentions that Colorado recently passed laws banning per- and polyfluoroalkyl substances (PFASs), which includes a deadline of 2027 for the phase-out of hydrofluoroolefins (HFOs) as propellants in cosmetics and fabric treatments. 

Manufacturers won't be permitted to utilize the current propellants in these aerosol products after that date, and they "are unsure of the ability of future products to comply with the OTC VOC content limits," the statement reads. However, the division's limitations on aerosol VOC concentration are expected to be reviewed in the future, according to the air quality commission. 

As of 19 July 2022, the U.S. Food and Drug Administration (FDA) requested information regarding uses of fluorinated polyethylene in food contact containers. This proposal is a part of ongoing efforts to guarantee the safety of authorized food contact uses, as fluorination of polyethylene may result in the creation of per- and polyfluoroalkyl substances (PFAS). The FDA is looking for scientific evidence and information on current uses of fluorinated polyethylene in food contact, consumer dietary exposure that may arise from those uses, and safety data on chemicals that may migrate from fluorinated polyethylene food containers. 

A marketing study on fluorinated polyethylene by the Environmental Defense Fund (EDF) found that its "uses vary from packaged food and consumer goods that individuals buy to larger containers used by shops like restaurants or larger drums used by businesses to store and transport fluids." 

Following the agency's 2021 discovery of per- and polyfluoroalkyl substances (PFASs) in some fluorinated barrels, just seven comments were submitted in response to a request for information (RFI). It's unclear how the agency will move given the scant response to the data call-in, which was completed on 18 October 2022.
