Section 335-3-6-.50 - Paint Manufacture(1) Except as otherwise required by the context, terms used in this Rule are defined in Rule 335-3-1-.02 or in this paragraph, as follows: (a) "Bottom Filling" means the filling of a tank in VOC service through an opening that is flush with the bottom of the tank.(b) "Conservation Vents" means a pressure-vacuum valve installed on a fixed roof tank that prevents the release of vapors during small changes in temperatures, barometric pressure, or liquid level.(c) "Enamel" means a glossy paint that forms a smooth hard coat after application and drying.(d) "Equipment" means each pump, valve, pressure relief valve, sampling connection, open-ended valve, and flange or connector in VOC service.(e) "In-VOC Service" means that the piece of equipment contains or contacts a fluid which is at least 10% VOC by weight.(f) "Paint" means a liquid suspension of finely divided pigment particles in a liquid composed of a resin or binder and volatile solvent. Paint includes water-based, solvent-based oil and alkyd paints.(g) "Repaired" means that equipment is adjusted or otherwise altered in order to eliminate indications of a leak.(h) "Submerged Filling" means the filling of a tank through a pipe or hose whose discharge is under the surface level of the liquid in the tank being filled.(i) "Varnish" means a homogeneous solution of natural or synthetic resins, dyes, and oils dispersed in organic solvents. The term varnish includes varnishes, resins, and lacquers.(2) This Rule shall apply to all facilities which have the potential to emit more than 90.7 Mg (100 tons) per year of VOCs from the manufacture or processing of paints, varnishes, lacquers, enamels, and other allied surface coating products.(3) The owner or operator of a paint, varnish, lacquer, enamel, and other allied surface coatings manufacturing or processing facility subject to this Rule shall meet the following equipment and operating requirements: (a) The owner or operator shall equip tanks storing VOC with a vapor pressure greater than 10 kPa (1.5 psi) at 20° C (68° F) with pressure/vacuum Conservation Vents set at + 0.2 kPa (0.029 psi), except where more effective air pollution control is used. Stationary VOC storage containers with a capacity greater than 946 liters (250 gallons) shall be equipped with a submerged-fill pipe or bottom fill, except where more effective air pollution control is used.(b) The owner or operator shall install covers on all open-top tanks used for the production of non-waterbase coating products. These covers shall remain closed except when production, sampling, maintenance or inspection procedures require operator access.(c) The owner or operator shall install covers on all tanks containing VOC used for cleaning equipment. These covers shall remain closed except when operator access is required.(d) The owner or operator shall operate and maintain all grinding mills according to the manufacturer's specifications. The manufacturer's specifications shall be kept on file at the facility and made available to the Director on request.(e) The owner or operator shall check each pump by visual inspection each calendar week for indications of liquids dripping from the pump seal. If there are indications of liquids dripping from the pump seal, it shall be repaired as soon as practicable, but no later than 15 calendar days after it is detected.(f) If any equipment in VOC service appears to be leaking on the basis of sight, smell, or sound, the following requirements shall apply: 1. a readily visible identification shall be attached to the leaking equipment. The identification may be removed upon repair.2. the leaking equipment shall be repaired with an initial attempt as soon as practicable, but no later than 15 calendar days after it is detected.3. when a leak is detected, the owners or operators shall record the date of detection and repair and the said record shall be retained at the facility in a readily accessible location for at least 2 years from the date of each detection or each repair attempt.(4) All gases or vapors from varnish cooking (resin reactor) operations shall be collected and passed through a control device which removes at least 85 percent of the VOC from such gases or vapors before they are discharged to the atmosphere.
