## Text

Section 391
Section 391.302  Sludge
Storage Design
a)         General
Off-site interim storage of sludge has created odors,
spillage, leachate and other environmental problems.  Consequently, the Agency
discourages sludge management plans that require off-site interim sludge
storage.  Where no other feasible alternative exists, the applicant shall
consider the following criteria.
b)         Specific Criteria for Off-site Interim Storage of Liquid or
Dried Sludge
1)         Off-site interim storage of liquid or dried sludge shall not
exceed 8 months.
2)         Provide a fence to preclude livestock and warning signs
designating the nature of the facility and advising against trespassing.
3)         Reduce visibility of storage site to general public and
maximize distance between site and any habitation.
4)         Use topographic features or wind breaks to take advantage of
wind effects of dispersion and/or reducing the movement of odorants away from
the source.
5)         Use wind breaks to prevent wave action in lagoons.
6)         Reduce exposed surface area by designing the deepest practical
and acceptable storage facility.
7)         Provide mixing equipment to maximize ease of removal of liquid
sludge from the storage facility and provide a homogeneous mixture.  Such
equipment should not generate aerosols.
8)         Only sludge that is stabilized so that odor production will not
occur may be placed in off-site interim storage facilities.
9)         In the event unexpected odor conditions do occur, the
responsible party managing the off-site storage facilities shall be prepared to
install and/or operate acceptable emergency odor control measures.
10)         Off-site interim storage facilities shall not be located
proximate to potable water supplies and other facilities subject to
contamination. Facilities should not be located in areas of porous soils and
fissured rock formations
ccur, the
responsible party managing the off-site storage facilities shall be prepared to
install and/or operate acceptable emergency odor control measures.
10)         Off-site interim storage facilities shall not be located
proximate to potable water supplies and other facilities subject to
contamination. Facilities should not be located in areas of porous soils and
fissured rock formations.  If such location is necessary the facility shall be
designed and constructed to protect groundwater and groundwater monitoring in
accordance with Section 391.440 shall be provided.
