SWPPP 2026 TEST QUESTIONS AND ANSWERS
SET A+
✔✔False ( it is sediment controls, NOT erosion controls that trap particles after they
have been detached) - ✔✔Erosion controls are BMPs that trap soil patricians after they
have been detached and are being transported by wind and water (T/F)
✔✔Gully, rill, rain drops, splash, and channel - ✔✔The following are common types of
erosion caused by water
✔✔Ground cover - ✔✔Of the following factors the one the contractor has the most
control over is
✔✔Vegetation - ✔✔Which erosion control BMP increases water and filtration dissipates
rain fall energy and slows over land flow of storm water
✔✔Amount of duration of rain fall, ground cover soil type - ✔✔Which of the following
factors effect erosion.
✔✔leave unprotected openings for storm water drains open - ✔✔Erosion and
sedimentation control principles do not include which of the following
✔✔False (14 days) - ✔✔Inactive areas on a construction site must be temporarily
stabilized within 21 days (T/F)
✔✔erosion controls treat soil as a non-renewable resource that has value and should
be kept in place - ✔✔The following control is a source control that treats soil as a non-
renewable source that has value and should be kept in place
✔✔False - ✔✔All design sites best specific erosion and sediment controls require no
inspections or maintenance (T/F)
, ✔✔A treatment train - ✔✔The system of erosion and sediment controls BMP's often
called
✔✔Manmade activities - ✔✔Accelerated erosion is caused by?
✔✔Ground cover - ✔✔Factors of erosion, the one that a contractor has most control
over is?
✔✔Minimize the extent of exposure... - ✔✔Of the following the one that is a primary
erosion and sediment control objective
✔✔consulting with project SWPPP designer or project owner and receiving written
approval - ✔✔SWPPP BMPs can be modified after?
✔✔Before construction activities begin - ✔✔Protecting vegetation should be
implemented when
✔✔It impedes the sheet from erosion as water flows down a slope and it provides an
area for seed germination and growth - ✔✔The benefits of soil or surface ruffling are?
✔✔1.) Properly prepare the seed bed 2.) Insure good seed to soil contact 3.) Install
specified short term protection such as erosion control blanket 4.) Provide ongoing
maintenance until ground cover is appropriately established - ✔✔When establishing
vegetation in ground cover the following steps should be followed.
✔✔Water soil until completely saturated is not a consideration before installing a rolled
erosion control product - ✔✔One thing not to be considered when installing a roll of
erosion controlled product (ACP)
✔✔diesel fuel emulsified in water - ✔✔Common materials and techniques used to
temporary stabilize construction site soils include all but one of the following
✔✔1.) Properly prepare site soils to meet top soil quality and quantity specification 2.)
develop a permanent stabilization plan early in a construction schedule 3.) mow and
maintain vegetation and landscape areas per contract requirements - ✔✔Pertaining to
the permanent stabilization is appropriate to
✔✔May not be used across stormwater convinces such as as ditch or swell - ✔✔Silt
fence may be used in all but one of the following locations
✔✔Ponding and settling - ✔✔Silt fence and fiber roll capture and retain sediment
primarily through
