(c) "Biosolids" are solid, semi-solid, or
liquid residue generated during the treatment of domestic sewage in a treatment
works. Biosolids include, but are not limited to, domestic septage; scum or
solids removed in primary, secondary, or advanced wastewater treatment
processes; and a material derived from biosolids. Biosolids do not include ash
generated during the firing of biosolids in a biosolids incinerator or grit and
screenings generated during preliminary treatment of domestic sewage in a
treatment works.
(d) "Biosolids
management facility" is any treatment works, land application system or person
who prepares or applies biosolids to the land and the owner/operator of a
surface disposal site.
(e) "Cover

harvest.
(f) "CWA" means the Clean
Water Act , 333 U.S.C.
1251 et seq.
(g) "Domestic septage" is either liquid or
solid material removed from a septic tank, cesspool, portable toilet, Type III
marine sanitation device, or similar treatment works that receives only
domestic sewage. Domestic septage does not include liquid or solid material
removed from a septic tank, cesspool, or similar treatment works that receives
either commercial wastewater or industrial wastewater and does not include
grease removed from a grease trap at a restaurant.
(h) "Domestic sewage" is waste and wastewater
from humans or household operations that is discharged to or otherwise enters a
treatment works.
(i) "Dry weight
basis" means calculated on the basis of having been dried at 105 degrees
Celsius until reaching a constant mass (i.e., essentially 100 % solids
content).
(j) "EPA" means the
United States Environmental Protection Agency.
(k) "Feed crops" are crops produced primarily
for consumption by animals.
(l)
"Fiber crops" are crops, such as flax and cotton, that are not produced for

(m) "Food crops" are
crops consumed by humans. These include, but are not limited to, fruits,
vegetables, and tobacco.
(n)
"Ground water" is subsurface water that fills available openings in rock or
soil material such that they may be considered water saturated under
hydrostatic pressure.
(o)
"Industrial wastewater" is wastewater generated in a commercial or industrial
process.
(p) "Municipality" means a
city, town, borough, county, parish, district, association, or other public
body (including an intermunicipal agency of two or more of the foregoing
entities) created by or under state law; or a designated and approved

includes a special district created under state law, such as a water district,
sewer district, sanitary district, utility district, drainage district, or
similar entity, or an integrated waste management facility as defined in
section 201(e) of the CWA, as amended, that has as one of its principal
responsibilities the treatment, transport, use, or surface disposal of
biosolids.
(q) "Permitting
authority" is the EPA and/or the Department of Environmental Quality, Water

(r) "Person who
prepares biosolids" is either the person who generates biosolids during the
treatment of domestic sewage in a treatment works or the person who derives a

(s) "Place
biosolids or biosolids placed" means disposal of biosolids on a surface
disposal site.
(t) "Pollutant" is
an organic substance, an inorganic substance, a combination of organic and
inorganic substances, or a pathogenic organism that, after discharge and upon
exposure, inges-tion, inhalation, or assimilation into an organism either
directly from the environment or indirectly by ingestion through the food
chain, could, on the basis of information available to the administrator of
EPA, cause death, disease, behavioral abnormalities, cancer, genetic mutations,
physiological malfunctions (including malfunction in reproduction), or physical
deformations in either organisms or offspring of the organisms.
(u) "Pollutant limit" is a numerical value
that describes the amount of a pollutant allowed per unit amount of biosolids
(e. g., milligrams per kilogram of total solids); the amount of a pollutant
that can be applied to a unit area of land (e. g., kilograms per hectare); or
the volume of a material that can be applied to a unit area of land (e.g.,
gallons per acre).
(v) "Runoff" is
rainwater, leachate, or other liquid that drains overland on any part of a land
surface and runs off of the land surface.
(w) "Store or storage of biosolids" is the
placement of biosolids on land on which the biosolids remains for two years or
less. This does not include the placement of biosolids on land for
treatment.
(x) "Treat or treatment
of biosolids" is the preparation of biosolids for final use or disposal. This
includes, but is not limited to, thickening, stabilization, and dewatering of
biosolids. This does not include storage of biosolids.
(y) "Treatment works" is either a federally
owned, publicly owned, or privately owned device or system used to treat
