1. Erosion: process in which, by the actions of wind and/or water, soil particles
detached and transported
2. Sediment: eroded material suspended in wind or water
3. Sedimentation: deposition of eroded material
4. Types of Erosion: splash
sheet
rill
gully
channel
5. Splash erosion: raindrop impact energy is enough to dislodge surface sediments
6. sheet erosion: caused by rain splash detaching soil particles lifting them up and
removing them by shallow "sheets" of water flowing down the sloped soil surface
7. Rill Erosion: as flow concentrates, small channels begin to form in the soil surface
8. Gully Erosion: Formed when runoff cuts rills deeper and wider or when flows
from several rills come together and form a large channels
9. Channel Erosion: may become unstable due to increased flows or changes in
upstream sediment load
10. Natural erosion: generally considered due to the influences of climate on the
surface of the earth
11. Accelerated erosion: natural erosion plus human activities
12. What problems can accelerated erosion cause?: Unrestricted development
removal of surface cover
increased imperviousness
poor stewardship
13. Problems associated with construction related erosion: problems for down
slope property owners
nuisance problems on streets
clog streams and storm drains
increased turbidity downstream
cover sensitive habitat with sediment
14. Identify instream damages of sediment: destruction of spawning areas, food
sources, habitat
direct toxicity to wildlife
lake degradation
filling of navigation channels
impacts to commercial fisheries
reduction of water storage capacities
15. Suspended material: sediment can affect light penetration, channel stability,
fisheries and habitat

16. Name Off stream damages: Increased flood hazards
increased water treatment costs
decreased capacity in conveyance facilities
higher infrastructure maintenance costs
17. What has increased the amount of impervious surface in our watersheds?-
: Urbanization and development
18. priority pollutants include: nutrients
pathogens
heavy metals
toxics
sediment
salts
detergents
hydro carbons
19. Clean Water Act (CWA): Federal Water Pollution Control Act enacted to restore
and maintain the chemical, physical and biological integrity of the waters of the US
administered by USEPA
20. Section 401: water quality certification
requires applicant, including any construction or operation of a facility, to obtain
certification to discharge ANY pollutant.
administered by the State
21. Section 402: NPDES Regs
22. NPDES: National Pollutant Discharge Elimination System
23. MS4: Municipal Separate Storm Sewers Systems
24. NURP: Nationwide Urban Runoff Program
1987-1983
led to EPA regulating stormwater
25. Phase I
(1987 - 1992): already covered by NPDES permit
facilities that engage in industrial activity
Large municipal storm systems (>250,000)
Medium municipal storms systems (100 - 250 K)
facilities that EPA said were significant contributors
26. Storm Water Implementation Rule: enacted April 1992, identified minimum
requirements for NPDES stormwater permits
27. Section 404: regulates dredge / fill permitting into waters of the US administered
by USACE

28. CZARA: Coastal Zone Act Reauthorization Amendments (CZARA) of 1990 re-
quires coastal zone states to develop Coastal Nonpoint Pollution Control Programs
section 6217 nonpoint source in coastal areas
29. stormwater: stormwater runoff, snow melt runoff, and surface runoff and
drainage
30. NPDES stormwater regulation say: stormwater must be in any discernable,
confined, and discrete conveyance, including but not limited to any pipe, ditch,
channel, tunnel, well, discrete fissure, container, rolling stock, concentrated feeding
operation....
31. waters of the US: waters used for interstate or foreign commerce
all interstate waters including wetlands
all other waters, the use ofr degeration of which would affect interstate or foreign
commerce
impoundments of waters
territorial sea
wetlands adjacent to waters above
32. Phase II: December 1999, require construction sites disturbing equal to or
greater than 1 acre and less than 5 to control pollutants in stormwater runoff.
33. SWMP: Stormwater Management Plan
34. 6 minimum measures of SWMP: Public Education and Outreach
Public Participation / Involvement
Illicit Discharge Detection and Elimination
Construction Site Runoff Control
Post Construction Runoff Control
Pollution Prevention / Good Housekeeping
(PPICPP)
35. Purpose of Clean Water Act: protect the beneficial uses of surface waters
36. Water quality standards must do the following: Include provisions for restor-
ing and maintaining the chemical, physical and biological integrity of state waters
Achieve a level of water quality that provides for the protection and propogration of
fish, shellfish and wildlife and recreation in an on the water
Consider the use and value of state waters for public water supplies, propagation of
fish and wildlife, recreation, agriculture and navigation
