Section 445B.22093 - Organic solvents and other volatile compounds1. Solvents or other volatile compounds such as paints, acids, alkalies, pesticides, fertilizers and manure must be processed, stored, used and transported in such a manner and by such means as to minimize the tendency to evaporate, leak, escape or be otherwise discharged into the ambient air causing or contributing to air pollution. If methods of control are available and feasible effectively to reduce the contribution to air pollution from evaporation, leakage or discharge, as determined by the Director, the installation and use of such methods, devices or equipment for control is mandatory.2. No person may place, store or hold in any new reservoir, stationary tank or other container with a capacity equal to or greater than 40,000 gallons (150 kiloliters) any gasoline, petroleum distillate, or volatile organic compound having a vapor pressure of 1.5 lb/square inch absolute (1,055 kg/square meter) or greater under actual storage conditions unless the tank, reservoir or other container is a pressure tank maintaining working pressure sufficient at all times to prevent loss of vapor or gas to the atmosphere or is equipped with one of the following devices properly installed, in good working order, and in operation: (a) A floating roof which consists of a pontoon type or double-deck roof which rests on the surface of the liquid contents and is equipped with a seal to close the space between the roof eave and tank wall or a vapor balloon or a vapor dome designed in accordance with accepted standards of the petroleum industry. This control equipment is not permitted if the gasoline or petroleum distillate has a vapor pressure of 11 lb/square inch absolute (7,734 kg/square meter) or greater under actual conditions. All gauging and sampling devices for tanks must be gastight except when gauging or sampling is taking place.(b) Other equipment proven to be of equal efficiency for preventing discharge of gases and vapors to the atmosphere.3. Any tank for the storage of any other petroleum or volatile organic compound which is constructed or extensively remodeled on or after November 7, 1975, must be equipped with a submerged fill pipe for the control of emissions.4. All facilities for dock loading of products consisting of petroleum or other volatile organic compounds having a vapor pressure of 1.5 lb/square inch absolute (1,055 kg/square meter) or greater at loading pressure must have facilities for submerged filling by a submerged fill pipe for the control of emissions.Nev.
