PART 34_FUEL VENTING AND EXHAUST EMISSION REQUIREMENTS FOR TURBINE 
ENGINE POWERED AIRPLANES--Table of Contents
 
  Subpart B_Engine Fuel Venting Emissions (New and In-Use Aircraft Gas 
                            Turbine Engines)
 
Sec.  34.11  Standard for fuel venting emissions.

    (a) No fuel venting emissions shall be discharged into the 
atmosphere from any new or in-use aircraft gas turbine engine subject to 
the subpart. This paragraph is directed at the elimination of 
intentional discharge to the atmosphere of fuel drained from fuel nozzle 
manifolds after engines are shut down and does not apply to normal fuel 
seepage from shaft seals, joints, and fittings.
    (b) Conformity with the standard set forth in paragraph (a) of this 
section shall be determined by inspection of the method designed to 
eliminate these emissions.
    (c) As applied to an airframe or an engine, any manufacturer or 
operator may show compliance with the fuel venting and emissions 
requirements of this section that were effective beginning February 1, 
1974 or January 1, 1975, by any means that prevents the intentional 
discharge of fuel from fuel nozzle manifolds after the engines are shut 
down. Acceptable means of compliance include one of the following:
    (1) Incorporation of an FAA-approved system that recirculates the 
fuel back into the fuel system.
    (2) Capping or securing the pressurization and drain valve.
    (3) Manually draining the fuel from a holding tank into a container.
