SDAPCD RULE 61.9 SEPARATION OF ORGANIC COMPOUNDS FROM WATER               
LAST REVISED 03/14/89

               
               RULE 61.9.SEPARATION OF ORGANIC COMPOUNDS FROM WATER
                         (Effective 3/14/89)

               (a)  APPLICABILITY

               Except as provided for in Section (b), this rule is
          applicable to any compartment of any device operated for the
          recovery of organic compounds from effluent water where the
          recovery can equal or exceed 200 gallons (757 liters) of organic
          compounds in any 24-hour period from any equipment which
          processes, refines, stores, or handles hydrocarbons having a true
          vapor pressure of 0.5 pounds per square inch absolute, or
          greater, at 100F.

               (b)  EXEMPTIONS - [Reserved]

                         (c)  STANDARDS

                    (1)  No person shall use any compartment of any device
               subject to this rule unless such compartment is equipped
               with one of the following vapor loss control devices:

                         (i)  A solid cover with all openings sealed and
                    totally enclosing the liquid contents of that
                    compartments, or

                         (ii) A floating cover in contact with the liquid
                    surface, equipped with closure seals that have no tears
                    or leaks, installed and maintained so that gaps between
                    the compartment wall and the seal shall not exceed 1/8
                    inch (0.32 centimeters) for an accumulative length of
                    97 percent of the perimeter of the compartment.  No gap
                    between the compartment wall and the seal shall exceed
                    1/2 inch (1.3 centimeters), or

                         (iii)An air pollution control system which reduces
                    the emissions of all hydrocarbon vapors and air
                    contaminants into the atmosphere by at least 90 percent
                    by weight, or

                         (iv) Other equipment with a control efficiency
                    equal to or greater than (i), (ii) or (iii) which is
                    approved by the Air Pollution Control Officer.

                    (2)  Each gauging or sampling port in any floating
               cover shall be equipped with a cover or lid.  The cover or
               lid shall be in a closed position at all times, except when
               the port is in actual use.  There shall be no gaps between
               the port cover or lid and the  compartment when the port
               cover or lid is closed.

                    No gauging or sampling port of a sealed compartment
               shall be opened if the compartment vapor space is under
               pressure and is connected to a vapor recovery system.  Each
               gauging or sampling port of any sealed compartment shall be
               gas tight except when the port is opened to allow the gauge
               to be read or a sample to be taken.
