WHY DO WE MONITOR OR SAMPLE?
The general permit says so!

SAMPLING REQUIREMENTS Sampling requirements established by 40 CFR Part 136 &
“NPDES Storm Water Sampling Guidance Document, EPA 833-B-92-011”
Containers labeled prior to collection Large, well cleaned glass or plastic jars should be used for
collecting samples The samples should be taken from the center of the
receiving water The container should be held so that it faces upstream The samples should be kept free of floating debris Samples should be analyzed within 48 hours after
collection Report results must be submitted to EPD using GEOS by
the 15th of the following month.

SAMPLING REQUIREMENTS Where sampling is required but not possible. The primary or
tertiary permitee must include a written justification in the inspection report.

Turbidity vs Total Suspended Solids –What is the difference? Turbidity is determined by the amount of light
scattered off of these particles. Turbidity is optical. Total Suspended Solids (TSS) are a total quantity
measurement of solid material per volume of water. TSS are a specific measurement of all suspended
solids, organic and inorganic. TSS can be used to calculate sedimentation rates and
turbidity cannot.

Grain size is classified as clay if the particle diameter is <0.002 mm, as siltif it is between 0.002 mm and 0.06 mm, or as sand if it is between 0.06 mm and 2 mm. Soil texture refers to the relative proportions of sand, silt, and clay particle sizes, irrespective of chemical or mineralogical composition.

BEST MANAGEMENT PRACTICE Are the BMP’s properly
designed, installed, and maintained?
If not, what happens?

Erosion / Sediment Loss
![Page 12: Joe Goodman OnSite Monitoring & Management, LLC...SAMPLING REQUIREMENTS Sampling requirements established by 40 CFR Part 136 & “NPDES Storm Water Sampling Guidance Document, EPA](https://reader036.vdocuments.us/reader036/viewer/2022071413/610c6238be391d2d63769327/html5/thumbnails/12.jpg)
EROSION / SEDIMENT LOSS Sediment is the #1 non-point source
pollutant
Erosion is Defined as the process by which the land is warn away by the action of water, wind, ice and gravity.
Sedimentation is the process by which the eroded material is TRANSPORTEDand DEPOSITED by water, wind, ice and gravity.

Correct BMP installation

RESUSPENSION Remove previous materials (Sedimentation) from an
issue. Address the issue at the source (REPAIR OR REPLACE
the BMP). Stabilize when ever possible.
