  "definition": "Storage vessels of any capacity and vapor pressure in a process at affected sources producing neoprene storing a liquid that is at least 0.1 percent by weight of chloroprene. If knowledge exists that suggests chloroprene could be present in a storage vessel, then the storage vessel is considered to be “in chloroprene service” unless the procedures specified in § 63.509 are performed to demonstrate that the storage vessel does not meet the definition of being “in chloroprene service”. The exemption for vessels “storing and/or handling material that contains no organic HAP, or organic HAP as impurities only” listed in the definition of “storage vessel” in this section does not apply for storage vessels that are in chloroprene service. Examples of information that could suggest chloroprene could be present in a storage vessel, include calculations based on safety data sheets, material balances, process stoichiometry, or previous test results provided the results are still relevant to the current operating conditions.",
