SCDHEC REGULATION 61-56
EXAM
Soil Texture - ANSWERS-The relative proportions of the three soil
separates (sand, silt, and clay) in a given sample of soil. The
percentages of each separate are used to determine which class a
particular sample falls into by plotting the intersection of these three
values on the U.S. Department of Agriculture (USDA) Natural
Resource Conservation Service (NRCS) Textural Triangle
Standard 610 - Specialized Onsite Wastewater System Design (less
than 1500 gpd) - ANSWERS-An onsite wastewater system that is
certified to function satisfactorily and in accordance with all
requirements of this regulation by virtue of it having been designed by
a Registered Professional Engineer (PE) licensed in South Carolina
with technical input from a licensed person meeting the criteria of
Section 102.1(2)(b) or (c). Such systems have limited application and
can only be utilized when the required engineering design,
certification, and technical soils documentation have been provided to
and accepted by the Department.
Standard - ANSWERS-A group of requirements developed by the
Department that specifies the minimum site conditions and design
criteria necessary for the approval of a specific type of onsite
wastewater system. A standard may also address minimum design
criteria for certain components of onsite wastewater systems as well
as methodologies for determining system sizing
,Stickiness - ANSWERS-The capacity of soil to adhere to other
objects. Stickiness is estimated in accordance with the Field Book at
the moisture content that displays the greatest adherence when
pressed between the thumb and forefinger.
Subsurface Wastewater Infiltration Area (Drain Field) - ANSWERS-A
specific area where a network of wastewater infiltration trenches or
other devices of sewage application are installed to provide the final
treatment and disposal of effluent.
Suspension - ANSWERS-The temporary or indefinite withdrawal or
cessation of rights and privileges granted by a license or onsite
wastewater system permit or approval, as applicable
Ultimate Tensile Strength - ANSWERS-A measure of the resistance
of a material to longitudinal stress, measured by the minimum
longitudinal stress required to rupture the material
Upgrade/Expansion - ANSWERS-Any work performed on an existing
onsite wastewater system for the purposes of increasing the capacity
of the system above its original design and/or accommodating wastes
of a different character than was originally approved.
Variance - ANSWERS-Means a written document issued by the
Department that authorizes a modification or waiver of one or more
requirements of this regulation, if in the opinion of the Department, a
health hazard or nuisance will not result from the modification or
waiver
, Wastewater Characteristics - ANSWERS-The physical, chemical, and
biological parameters and characteristics of domestic wastewater.
Physical characteristics include turbidity, color, odor, total suspended
solids (TSS), temperature and fats, oils and grease (FOG). Chemical
characteristics include the presence and extent of chemical oxygen
demand (COD), total organic carbon (TOC), Total Kjeldahl Nitrogen
(TKN), nitrogen, phosphorous, chlorides, sulfates, alkalinity, pH,
heavy metals, trace elements, and priority pollutants identified by the
U.S. Environmental Protection Agency (EPA). Biological
characteristics include biological oxygen demand (BOD), oxygen
required for nitrification and microbial population. High strength
wastewater is characterized as meeting one (1) or more of the
following levels: BOD > 350 mg/l, TSS > 100 mg/l, TKN > 100 mg/l,
FOG > 30 mg/l.
Wastewater Combustion System - ANSWERS-self-contained system
for wastewater treatment that uses water as a medium for transport
and storage. It treats and renders wastewater inert using maceration
and incineration
Wastewater Infiltration Trench - ANSWERS-A trench installed in the
naturally occurring soil that is utilized for the treatment and disposal
of domestic wastewater.
Wastewater Treatment Facility - ANSWERS-An accessible publicly
or privately owned system of structures, equipment, and related
appurtenances that treat, store, or manage wastewater
