Rainfall erosivity waiver - CORRECT ANSWER - The option of allowing a small
construction site (>1 and <5 acres) to self-certify if the rainfall erosivity value (R value) for their
site's given location and time frame compute to be less than or equal to 5.
ATS (Active Treatment Systems) - CORRECT ANSWER - There are instances on
construction sites where traditional erosion and sediment controls do not effectively control
accelerated erosion. Under such circumstances, or under circumstances where storm water
discharges leaving the site may cause or contribute to an exceedance of a water quality standard,
, the use of an Active Treatment System (ATS) may be necessary. Additionally, it may be
appropriate to use an ATS when site constraints inhibit the ability to construct a correctly sized
sediment basin, when clay and/or highly erosive soils are present, or when the site has very steep
or long slope lengths.
