CEPSCI VERIFIED ACCURATE STUDY GUIDE
Erosion - Answers - The process by which the land surface is worn away by the action
of water wind ice and gravity.
Factors contributing to erosion - Answers - Climate (rain frequency), Season (storms in
summer), vegetative cover, topography, soil characteristics.
Sedimentation - Answers - Process by which eroded material is transported and
deposited
Sedimentation effects: - Answers - reduces water clarity, fills up ponds/reservoirs,
pollutants attached to sediment impact water quality.
1972 Clean Water Act - Answers - Administered by EPA, created the National Pollutant
Discharge Elimination System (NPDES)
NPDES in South Carolina - Answers - SC is an NPDES delegated state. NPDES
regulations are administered by South Carolina Department of Health and
Environmental Control (DHEC).
epa DOES HAVE authority to exert jurisdiction in SC.
Department of Health and Environmental Control (DHEC) - Answers - state body that
administers NPDES regulations. Construction General Permit is administered by DHEC
Construction General Permit - Answers - Affects both small and large construction
activities. Must be obtained for land disturbing activities of:
- 1 acre or greater
- Less than 1 acre but within a 1/2 mile of a water body in the coastal counties)
- Less than 1 acre of total land area that is part of a larger common plan of
development if the development will end up disturbing more than 1 acre.
Operator categories: - Answers - Primary permittee: developer, land owner, site
operator, public/private entity
Secondary Permittee: Residential builder, lot owner
Contractors
lending institutions
Primary Permittee - Answers - They have operational control over Stormwater Pollution
Prevention Plan (SWPPP), construction plans, and specifications.
, typically owner or developer
How to obtain coverage under Construction General Permit: - Answers - 1. Submit a
Notice of Intent
2. Preparation of the Comprehensive Stormwater Pollution Prevention Plan (C-SWPPP)
Secondary Permittee - Answers - Conducts land disturbing activity limited to an
individual lot or group of lots. This is Ryan Homes
Contractors - Answers - Employed by the primary or secondary permittees. Before
starting work, they must participate in pre-construction conference and complete Pre-
Construction Conference Certification Form
As well as a Contractor Certification Form
Lending Institution - Answers - If a bank or government entity takes over a site due to
forclosure, they become responsible for site discharge
Stormwater Pollution Prevention Plans - Answers - SWPPP is a site specific document
that:
- identifies sources of stormwater pollution
- describes control measure to reduce pollutants in site discharge
- identifies procedures for the operator to implement to comply with CGP
Comprehensive SWPPP vs. On-Site SWPPP - Answers - Comprehensive: includes
calculations
On-Site: includes certification forms and records/logs.
They otherwise both have a narrative, maps, sequences, and Notices of Intent
On-Site SWPPP - Answers - must be kept on site or posted near main entrance.
Must include:
1. DHEC Construction General Permit
2. Notice of Intent
3. NPDES Coverage Approval Letter
4. Pre-Construction Conference Certification Forms
5. Contractor Certifications
