Title: 14 - Buildings and Constructions

Chapter: 12 - On-Site Sewage Disposal Systems

Section: 120 - Definitions

A.  "Alternative system" is defined in Section 14.12.080, subdivision I.

B.  "Building Official" means the Del Norte County Building official and his or her designees.

C.  "Conventional on-site waste treatment and disposal systems" means any system using a standard septic tank for treatment and standard leaching trenches or seepage pit for effluent disposal.

D.  "Cumulative effects" means the persistent and/or increasing effect of individual waste treatment and disposal systems resulting from the density of such discharges in relation to the assimilative capacity of the ground environment. Examples include salt or nitrate additions to groundwater, nutrient groundwater and between adjacent systems.

E.  "Ephemeral stream" means any observable watercourse that flows only in direct response to precipitation. It receives no water from springs and no long-continued supply from melting snow or other surface source. Its stream channel is at all times above the local water table. Any watercourse that does not meet this definition is to be considered a perennial stream for the purposes of this policy.

F.  "Failure" means the ineffective treatment and disposal of waste resulting in the surfacing of sewage effluent and/or the degradation of ground surface water quality.

G. "Greywater" means all waters generated in a household, or industrial and/or commercial place of business which do not contain toilet wastes.

H.  "Health Officer" means the Del Norte County Health Officer and his or her designees.

I.  "Groundwater" means any subsurface body of water which is beneficially used or is usable. It includes perched water if such water is used or usable, or is hydraulically continuous with used or usable water."

J.  "Non-standard" means an alternative system.

K.  "Incompatible use" means any activity or land uses that would preclude or damage an area for future use as an effluent disposal site. Includes the construction of buildings, roads or other permanent structures and activities that may result in the permanent compaction or removal of existing soil.

L.  "On-site sewage disposal system" means any existing or proposed on-site sewage disposal system including, but not

limited to a standard subsurface, alternative, experimental or non-water-carried sewage disposal system, installed or

proposed to be installed on land of the owner of the system.

M.  "Perennial stream" means any stretch of a stream that can be expected to flow continuously or seasonally. They are generally fed in part by springs.

N. "Permit" means the written document issued by the county which authorizes the permittee to install a system or any part thereof, which may also require operation and main­tenance of the system.

O.  "Septic tank" means a watertight receptacle which receives sewage from a sanitary drainage system, is designed to separate solids from liquids, digest organic matter during a period of detention, and allow the liquids to discharge to a second treatment unit or to a soil absorption facility.

P.  "Septic tank effluent" means partially treated sewage which is discharged from a septic tank.

Q.  "Sewage" means water-carried human wastes, including kitchen, bath, and laundry wastes from residences, build­ings, industrial establishments, or other places.

R. "Standard system" means prescriptive standard of on-site sewage disposal system consisting of a septic tank, distribu­tion unit (if applicable), and gravity-fed absorption facility constructed in accordance with the provisions of this chapter and allow consideration of localized factors.

S.  "Soil" means the unconsolidated material on the surface of the earth that exhibits properties and characteristics that are a product of the combined factors of parent material, climate, living organisms, topography, and time.

T.  "Unstable landform" means an area which shows evidence of mass downslope movement such as debris flow, land­slides, rockfills, and hummocky hill slopes with undrained depressions upslope. Unstable landforms may exhibit slip surfaces roughly parallel to the hillside landslide scars and curving debris ridges fences, trees, and telephone poles which appear tilted or tree trunks which bend uniformly as they enter the ground. Active sand dunes are unstable landforms.
