SCDHEC REGULATION 61-56 EXAM
QUESTIONS AND ANSWERS 2026
VERIFIED.
Alternative System - ANS A system incorporating design modifications of the proposed
subsurface wastewater infiltration trench area (drain field) or absorption trench geometry for
the purpose of achieving compliance with required setbacks and offset to the zone of saturation
and/or restrictive horizons. No such system shall be utilized unless the Department has
established a specific standard.
Alternative Infiltration Trench Products - ANS Products specifically designed to replace or
eliminate the aggregate typically utilized in subsurface infiltration trenches. Such products must
be approved for use by the Department and must adhere to required equivalency values
established herein.
Bond - ANS A sum of money set aside (Surety Bond) to insure completion of work under a
contract.
Canal - ANS An artificial waterway used for navigation, drainage, or irrigation.
Cleaning - ANS The removal and transportation of septage from an onsite wastewater
system, self-contained toilet, or other sewage holding system to an approved disposal location.

, Color Charts (Munsell System or equivalent) - ANS Charts bearing various color chips
established by a recognized color system which uses three elements—hue, value, and chroma—
to make up a specific color notation. The notation is recorded in the form of hue, value, and
chroma (e.g., 10YR 5/6). The three attributes of color are arranged in the system in orderly
scales of equal visual steps, which are used to measure and describe color accurately under
standard conditions of illumination by comparing soil samples to color chips on various charts.
Conventional System - ANS An onsite wastewater system that utilizes a network of
conventional wastewater infiltration trenches installed in the naturally occurring soil for the
treatment and disposal of domestic wastewater.
Critical Area - S. C. Code Section 48-39-10(J) defines critical area as the following - ANS 1)
coastal waters; 2) tidelands; 3) beaches; 4) beach/dune systems which are the areas from the
mean high-water mark to the setback line as determined in S. C. Code Section 48-39-280.
Curtain Drain - ANS A subsurface interceptor drain that is installed to collect and redirect
groundwater as it flows through the soil profile to an appropriate discharge point.
Ditch - ANS A long narrow excavation intended for the purpose of drainage and/or irrigation.
Domestic Wastewater - ANS The untreated liquid and solid human body waste and the
liquids generated by water-using fixtures and appliances, including those associated with food
service operations. For the purposes of this regulation, domestic wastewater shall not include
industrial process wastewater.
Dwelling - ANS A self-contained unit used by one (1) or more households as a home, such as
a house, apartment, mobile home, house boat, tiny house, park model RV, RV or camper, or
other substantial structure that provides living facilities for one (1) or more persons, including
permanent or semi-permanent provisions for living, sleeping, eating, cooking, and sanitation.
