STATE OF FLORIDAEROSION AND SEDIMENT CONTROL

DESIGNER AND REVIEWER MANUAL

A state wide multi agency manual

Helps in the design of erosion and sediment control (E&SC) structures and Stormwater Pollution Prevention Plans (SWPPPs)

It is a guidance manual

Full of examples and pictures

Basic Principle: no discharge should violate the state’s water quality standard for turbidity

through System– Toxicity Requirements and Index Testing– Inspection and Maintenance Requirements

Mixer logs measured 140 square inch surface area:188.4 in. sq. (test log) = 24.4 mg/L for the 706b polymer log 140 in. sq. (mixer log) = 18.1 mg/L for the 706b polymer log

8 logs/mixer = 145.1 mg/L dosage 188.4 in. sq. (test log) = 12.2 mg/L for the 703d polymer log 140 in. sq. (mixer log) = 9.07 mg/L for the 703d polymer log

8 logs/mixer = 72.5 mg/L dosage

Total dosage for the system is 217.6 mg/L

Calculations in each example

When and How

•The manual will be available on line.•We anticipate distribution in May of this year. •Everyone at the workshop, if we have your correct email

will be sent notice of the availability.•Other notifications will be sent from FDOT and FDEP •There will be classes to help to understand and apply the

the contents of the manual.•Also stay tuned for a companion field manual.
