Sec.  445.2  General definitions.



    In addition to the definitions set forth in 40 CFR 122.2, 257.2, 

258.2, 264.10, 265.10, 401.11, and 403.3 the following definitions apply 

to this part:

    (a) Contaminated ground water means water below the land surface in 

the zone of saturation which has been contaminated by activities 

associated with waste disposal.

    (b) Contaminated storm water means storm water which comes in direct 

contact with landfill wastes, the waste handling and treatment areas, or 

landfill wastewater as defined in paragraph (f) of this section. Some 

specific areas of a landfill that may produce contaminated storm water 

include (but are not limited to): the open face of an active landfill 

with exposed waste (no cover added); the areas around wastewater 

treatment operations; trucks, equipment or machinery that has been in 

direct contact with the waste; and waste dumping areas.

    (c) Landfill directly associated with an industrial or commercial 

operation means:

    (1) A landfill located on the same site as industrial or commercial 

operations; and

    (2) A landfill not located on the same site as the industrial or 

commercial operations (off-site), but ``wholly-owned'' by the industrial 

or commercial facility and primarily dedicated to receiving waste from 

the related industrial or commercial facility.

    (d) Facility means all contiguous property owned, operated, leased 

or under the control of the same person or entity.

    (e) Landfill unit means an area of land or an excavation in which 

wastes are placed for permanent disposal, that is not a land application 

or land treatment unit, surface impoundment, underground injection well, 

waste pile, salt dome formation, a salt bed formation, an underground 

mine or a cave as these terms are defined in 40 CFR 257.2, 258.2 and 

264.10.

    (f) Landfill wastewater means all wastewater associated with, or 

produced by, landfilling activities except for sanitary wastewater, non-

contaminated storm water, contaminated ground water, and wastewater from 

recovery pumping wells. Landfill wastewater includes, but is not limited 

to, leachate, gas collection condensate, drained free liquids, 

laboratory derived wastewater, contaminated storm water and contact 

washwater from washing truck, equipment, and railcar exteriors and 

surface areas which have come in direct contact with solid waste at the 

landfill facility.

    (g) Non-contaminated storm water means storm water which does not 

come in direct contact with landfill wastes, the waste handling and 

treatment areas, or landfill wastewater that is defined in paragraph (f) 

of this section. Non-contaminated storm water includes storm water which 

flows off the cap, cover, intermediate cover, daily cover, and/or final 

cover of the landfill.

    (h) Off-site means outside the boundaries of a facility.

    (i) On-site means within the boundaries of a facility.

    (j) Public service means the provision of landfill waste disposal 

services to individual members of the general public, publicly-owned 

organizations (schools, universities, government agencies, 

municipalities) and not-for-profit organizations for which the landfill 

does not receive a fee or other remuneration.

    (k) The regulated parameters for this part, numbered (P) and listed 

with approved methods of analysis in Table 1B at 40 CFR 136.3, are 

defined as follows:

    (1) Ammonia (as N) means ammonia reported as nitrogen. P4.

    (2) BOD5 means 5-day biochemical oxygen demand. P9.

    (3) Arsenic means total arsenic. P6.

    (4) Chromium means total chromium. P19.

    (5) Zinc means total zinc. P75.

    (l) The regulated parameters for this part, numbered (P) and listed 

with approved methods of analysis in Table 1C at 40 CFR 136.3, are as 

follows:

    (1) Naphthalene. P68.

    (2) Phenol. P85.
