Exemptions. The
requirements of this section shall not apply to the following:
(1) Process components of a domestic
wastewater treatment facility which is subject to a CDPS permit issued pursuant
to section
25-8-501 of the Act, C.R.S., 1973,
as amended, or to the process components of a domestic wastewater treatment
facility site approval and plans and specifications approval pursuant to

permitted land application site, which are intended for the offloading of
biosolids from vehicles transporting biosolids to an application site and
subsequent loading of biosolids into application equipment, including any
incidental spillage or placement on the land during transfer. Such areas shall
be protected or managed so as to prevent movement of spillage or runoff from
the transfer area, off of the permitted land application site.
(5) Tankage. Such facilities shall be bermed
or otherwise protected so as to prevent movement of spillage or runoff from the
storage area off of the permitted site.
(6) Short Term Storage - Staging Area, within
a permitted land application site, for the storage of dewatered biosolids for a
period of fourteen days or less, or temporary storage for a longer period upon
site-specific Division approval at that time. These areas shall be protected or
managed so as to prevent biosolids and/or runoff from escaping the permitted
land application site. If approval is sought for a period in excess of two
weeks, the applicant may also be required to address the potential need for
control of leachate generated as a result of such storage.
C.
General Requirements for
Storage. No person shall use any facility for biosolids storage
unless the facility, and the biosolids to be stored therein, meet the following
requirements:
(1) At the time biosolids are
placed in the storage facility, all biosolids which are stored shall meet, at a
minimum, Class B pathogen destruction criteria as described in section 64.12(B)
of these regulations.
(2) At the
time biosolids are placed in the storage facility, all biosolids which are

following requirements:
(1) The bottom of the
biosolids storage facilities shall consist of an impermeable material or shall
be constructed with an underdrain system and the facilities shall be bermed or
otherwise protected so as to prevent movement of spillage or runoff from the
storage facilities off of the permitted site. For purposes of this section
64.13 , the term "impermeable material" means any synthetic or naturally
occurring material which will allow leachate to seep no more than 1/16 of an
inch per day through surrounding or underlying material, or
(2) The storage facilities shall be covered
and either shall be bermed or otherwise protected so as to prevent movement of
spillage or runoff from the storage facilities off of the permitted site, or
runoff from the cover shall be collected and directed away from the storage
facilities.
