Maryland HFC Reduction Program
COMAR 26.11.33 - Prohibition on Use of Certain Hydroflourocarbons

Subsequently, manufacturers will provide annual updates to the Department if they continue to use certain HFC products. Manufacturers whose products do not contain a restricted substance are exempt from these requirements.
