PART 503 DEFINITIONS

                                       THERE IS NO DEFINITION FOR BIOSOLIDS


503.9(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 (humans) or
offspring (children) of the organisms.

[NOTE: This definition specifically relates as well to the nine pollutants listed in
503.13


"Domestic sewage is waste and waste water from humans or household operations that is discharged to
or otherwise enters
a treatment works." (40 CFR 503.9(g)).  Rubin claims, "This is a key definition,
because the standards in the part 503 regulation apply to sewage sludge generated during the treatment
of domestic sewage in a treatment works. When domestic sewage is in the influent to a treatment works,
even if the influent also contains industrial wastewater, sewage sludge is generated during the treatment
of the domestic sewage." (FR. 58, p. 9326 - 40 CFR 257 et al. (503))

503.9(aa)
Treatment works is either a federally owned, publicly owned, or privately owned device or
system used to treat (including recycle and reclaim)
either domestic sewage or a combination of
domestic sewage and industrial waste of a liquid nature.

However, in a letter dated Feb. 7, 1986, from, The (EPA) Administrator, to the Honorable Thomas P.
O'Neil, Jr., Speaker. U.S. House of Representatives,  stated: "The purpose of the Domestic Sewage Study
was to evaluate the impacts of waste discharged to public owned treatment works (POTW's) as a result of
the Domestic Sewage Exclusion. The Domestic Sewage Exclusion, (specified in Section 1004(27) of
RCRA) provides that a hazardous waste, when mixed with domestic sewage is no longer considered
hazardous. Therefore, POTW's receiving hazardous waste in this manner are not subject to the RCRA
treatment, storage and disposal facility requirements. The premise behind the Domestic Sewage Exclusion
is that RCRA management of wastes
within a POTW is unnecessary and redundant since this wastes
are regulated under the Clean Water Act's regulatory programs."

RCRA (27) The term ``solid waste'' means any garbage, refuse, sludge from a waste treatment plant,
water supply treatment plant, or air pollution control facility

"Sludge means any solid, semi-solid, or liquid waste generated from a municipal, commercial, or industrial
wastewater treatment plant, water supply treatment plant, or air control facility exclusive of the treated
effluent (clean water) from a wastewater treatment plant." (Public Laws. (1987). "The SOLID WASTE
DISPOSAL ACT, AS AMENDED BY, THE HAZARDOUS AND SOLID WASTE AMENDMENTS OF 1984
(PUBLIC LAW 98- 616); THE SAFE DRINKING WATER ACT AMENDMENTS OF 1986 (PUBLIC LAW 99-
339); AND THE SUPERFUND AMENDMENTS AND REAUTHORIZATION ACT OF 1986 (PUBLIC LAW 99-
499)." 99th Congress, 1st Session. Committee Print for S. Prt. 99-215)

program. [Only six states have applied and received EPA approval]


§ 503.9   General definitions.

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 the Federal Water Pollution Act or the

95–217, Public Law 95–576, Public Law 96–483, Public Law 97–117, and Public Law 100–4.

(f) 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.

(g) Domestic sewage is waste and wastewater from humans or household operations that is discharged to
