(4) CLEANING DEVICES AND METHODS REQUIREMENTS. Except as provided under sub. (6), by November 1, 2009, the owner or operator of a facility shall comply with the following requirements associated with the identified cleaning devices or methods when using solvents or solvent solutions: (a) Physically rub a surface with a porous applicator such as a rag, paper, sponge, or a cotton swab moistened with solvent or solvent solution.(b) Closed containers or hand held spray bottles from which solvents or solvent solutions are applied without a propellant-induced force.(c) Cleaning equipment which has a solvent or solvent solution container that is closed during cleaning operations, except when depositing and removing objects to be cleaned, and is closed during non-operation with the exception of maintenance and repair to the cleaning equipment itself.(d) A remote reservoir cleaner operated in compliance with all of the following requirements:1. Solvent vapors are prevented from escaping from the solvent or solvent solution container by using devices such as a cover or a valve when the remote reservoir is not being used, cleaned, or repaired.2. Flow is directed in a manner that prevents solvent or solvent solution from splashing outside of the remote reservoir cleaner.3. The cleaner is not used for cleaning porous or absorbent materials, such as cloth, leather, wood, or rope.4. Only solvent or solvent solution containers free of all liquid leaks are used. Auxiliary equipment, such as pumps, pipelines, or flanges, may not have any liquid leaks, visible tears, or cracks. Any liquid leak, visible tear, or crack detected shall be repaired within one calendar day, or the leaking section of the remote reservoir cleaner shall be drained of all solvents or solvent solutions and shut down until it is replaced or repaired.(e) A non-atomized flow method where the used solvents or solvent solutions are collected in a container or a collection system which is closed, except for the solvent or solvent solution collection openings that may be open when filling or emptying, or the opening caused by use of a pressure relief valve.(f) A flushing method where the used solvents or solvent solutions are discharged into a container which is closed, except for the solvent or solvent solution collection openings that may be open when filling or emptying, or the opening caused by use of a pressure relief valve. The discharged solvents or solvent solutions shall be collected into containers without atomizing into the open air.(5) STORAGE, DISPOSAL, AND TRANSPORT. The owner or operator of a facility shall store all solvents or solvent solutions used in industrial cleaning operations in non-absorbent, non-leaking containers which shall be kept covered except when filling or emptying. Cloth and paper moistened with solvents or solvent solutions shall be stored in covered, non-absorbent, non-leaking containers. VOC-containing cleaning materials shall be conveyed in closed containers or pipes.(6) CONTROL EQUIPMENT. In lieu of complying with the requirements in sub.
