CEPSCI CERTIFICATION EXAM
CEPSCI CERTIFICATION EXAM WITH GUARANTEED ACCURATE ANSWERS
Why erosion prevention and sediment control are important? -
ACCURATE ANSWERS✔✔ 1. Stormwater runoff is leading cause of
impaired water in SC. 2. Protect downstream surface water and aquatic
habitats
Erosion - ACCURATE ANSWERS✔✔ Process by which land surface is
worn away by action of water, wind, ice and gravity.
Natural erosion - ACCURATE ANSWERS✔✔ aka Geologic erosion. 1.
relative slow 2. most rapid along shorelines and stream channels 3.
produces about 30% of eroded sediment in US
Accelerated erosion - ACCURATE ANSWERS✔✔ 1. erosion at
elevated rate bc of human activity 2. agriculture, timber harvesting and
,construction are primary contributors 3. accounts for remaining 70% of
eroded sediment in US
Factors influencing erosion - ACCURATE ANSWERS✔✔ 1. climate
(frequency, intensity and duration of rainfall for a region) 2. season
(more intense storms in summer) 3. vegetative cover 4. topography 5.
soil characteristics (texture, percentage of organic content, structure, and
permeability)
Sedimentation - ACCURATE ANSWERS✔✔ Process by which eroded
material is transported and deposited.
Negative impacts of sedimentation - ACCURATE ANSWERS✔✔ 1.
screens out sunlight/reduces water clarity. 2. fills channels and reduces
capacity. 3. pollutants attached to sediment particles can impact
downstream water quality.
NPDES - ACCURATE ANSWERS✔✔ aka National Pollutant
Discharge Elimination System. Created by the 1972 Clean Water Act.
1987 - ACCURATE ANSWERS✔✔ Amendment to CWA called Water
Quality Act required EPA to develop program to regulate storm
discharges under NPDES program.
Point source pollution - ACCURATE ANSWERS✔✔ Discharges from
readily identifiable sources such as wastewater treatment plants or
industrial facilities.
, Nonpoint source pollution - ACCURATE ANSWERS✔✔ Discharges
that are less easily identifiable such as runoff from urbanized or
agricultural areas.
DHEC - ACCURATE ANSWERS✔✔ aka Department of Health and
Environmental Control. This regulation administers NPDES regulations,
but EPA has authority to exert jurisdiction in SC.
CGP - ACCURATE ANSWERS✔✔ aka Construction General Permit.
One of several NPDES permits administered by DHEC.
Who must obtain NPDES coverage? - ACCURATE ANSWERS✔✔ 1.
land disturbing activities greater than or equal to 1 acre. 2. land
disturbance less than 1 acre within half a mile of a receiving water body
in SC Coastal Zone. 3. Exception: SFR development NOT part of larger
common plan of development.
Who is permitted? - ACCURATE ANSWERS✔✔ NPDES permits are
always issued to operator (person or company) for a particular discharge.
NOT issued to parcel or project.
Authorization of Discharges - ACCURATE ANSWERS✔✔ To receive
coverage under permit, appropriate Notice of Intent (NOI) form must be
completed and submitted. There are 3 types of NOIs and dependent on
the Operator Category (refer to chart).
