AND PRACTICES--Table of Contents

 

    Subpart A_Classification of Solid Waste Disposal Facilities and 

                                Practices

 

Sec.  257.3-8  Safety.



    (a) Explosive gases. The concentration of explosive gases generated 

by the facility or practice shall not exceed:

    (1) Twenty-five percent (25%) of the lower explosive limit for the 

gases in facility structures (excluding gas control or recovery system 

components); and

    (2) The lower explosive limit for the gases at the property 

boundary.

    (b) Fires. A facility or practice shall not pose a hazard to the 

safety of persons or property from fires. This may be accomplished 

through compliance with Sec.  257.3-7 and through the periodic 

application of cover material or other techniques as appropriate.

    (c) Bird hazards to aircraft. A facility or practice disposing of 

putrescible wastes that may attract birds and which occurs within 10,000 

feet (3,048 meters) of any airport runway used by turbojet aircraft or 

within 5,000 feet (1,524 meters) of any airport runway used by only 

piston-type aircraft shall not pose a bird hazard to aircraft.

    (d) Access. A facility or practice shall not allow uncontrolled 

public access so as to expose the public to potential health and safety 

hazards at the disposal site.

    (e) As used in this section:

    (1) Airport means public-use airport open to the public without 

prior permission and without restrictions within the physical capacities 

of available facilities.

    (2) Bird hazard means an increase in the likelihood of bird/aircraft 

collisions that may cause damage to the aircraft or injury to its 

occupants.

    (3) Explosive gas means methane (CH4).

    (4) Facility structures means any buildings and sheds or utility or 

drainage lines on the facility.

    (5) Lower explosive limit means the lowest percent by volume of a 

mixture of explosive gases which will propagate a flame in air at 25 

[deg]C and atmospheric pressure.

    (6) Periodic application of cover material means the application and 

compaction of soil or other suitable material over disposed solid waste 

at the end of each operating day or at such frequencies and in such a 

manner as to reduce the risk of fire and to impede disease vectors' 

access to the waste.

    (7) Putrescible wastes means solid waste which contains organic 

matter capable of being decomposed by microorganisms and of such a 

character and proportion as to be capable of attracting or providing 

food for birds.
