Sec. 503.9  General definitions.

    (a) Apply sewage sludge or sewage sludge applied to the land means

    (c) Class I sludge management facility is any publicly owned 
treatment works (POTW), as defined in 40 CFR 501.2, required to have an 
approved pretreatment program under 40 CFR 403.8(a) (including any POTW 
located in a State that has elected to assume local program 
responsibilities pursuant to 40 CFR 403.10(e)) and any treatment works 
treating domestic sewage, as defined in 40 CFR 122.2, classified as a 
Class I sludge management facility by the EPA Regional Administrator, 
or, in the case of approved State programs, the Regional Administrator 
in conjunction with the State Director, because of the potential for its 
sewage sludge use or disposal practice to affect public health and the 
environment adversely.
    (d) Cover crop is a small grain crop, such as oats, wheat, or 
barley, not grown for harvest.
    (e) CWA means the Clean Water Act (formerly referred to as either

grease removed from a grease trap at a restaurant.
    (g) Domestic sewage is waste and wastewater from humans or household 
operations that is discharged to or otherwise enters a treatment works.
    (h) 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 percent solids content).
    (i) EPA means the United States Environmental Protection Agency.
    (j) Feed crops are crops produced primarily for consumption by 
animals.
    (k) Fiber crops are crops such as flax and cotton.
    (l) Food crops are crops consumed by humans. These include, but are 
not limited to, fruits, vegetables, and tobacco.
    (m) Ground water is water below the land surface in the saturated 
zone.
    (n) Industrial wastewater is wastewater generated in a commercial or 
industrial process.
    (o) 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; an Indian tribe or an authorized Indian tribal organization

approved management Agency under section 208 of the CWA, as amended. The 
definition 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 disposal of sewage sludge.

    (r) Person who prepares sewage sludge is either the person who 
generates sewage sludge during the treatment of domestic sewage in a 
treatment works or the person who derives a material from sewage sludge.
    (s) Place sewage sludge or sewage sludge placed means disposal of 
sewage sludge 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, ingestion, 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 sewage sludge (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) Sewage sludge is solid, semi-solid, or liquid residue generated

    (bb) Wetlands means those areas that are inundated or saturated by
