Sec. 77.215  Refuse piles; construction requirements.

    (a) Refuse deposited on a pile shall be spread in layers and 
compacted in such a manner so as to minimize the flow of air through the 
pile.
    (b) Refuse shall not be deposited on a burning pile except for the 
purpose of controlling or extinguishing a fire.
    (c) Clay or other sealants shall be used to seal the surface of any 
refuse pile in which a spontaneous ignition has occurred.
    (d) Surface seals shall be kept intact and protected from erosion by 
drainage facilities.
    (e) Refuse piles shall not be constructed so as to impede drainage 
or impound water.
    (f) Refuse piles shall be constructed in such a manner as to prevent 
accidental sliding and shifting of materials.
    (g) No extraneous combustible material shall be deposited on refuse 
piles.
    (h) After October 31, 1975 new refuse piles and additions to 
existing refuse piles, shall be constructed in compacted layers not 
exceeding 2 feet in thickness and shall not have any slope exceeding 2 
horizontal to 1 vertical (approximately 27 deg.) except that the 
District Manager may approve construction of a refuse pile in compacted 
layers exceeding 2 feet in thickness and with slopes exceeding 27 deg. 
where engineering data substantiates that a minimum safety factor of 1.5 
for the refuse pile will be attained.
    (i) Foundations for new refuse piles and additions to existing 
refuse piles shall be cleared of all vegetation and undesirable material 
that according to current, prudent engineering practices would adversely 
affect the stability of the refuse pile.
    (j) All fires in refuse piles shall be extinguished, and the method 
used shall be in accordance with a plan approved by the District 
Manager. The plan shall contain as a minimum, provisions to ensure that 
only those persons authorized by the operator, and who have an 
understanding of the procedure to be used, shall be involved in the 
extinguishing operation.
