Slide 14

Storm Water Pollution Prevention Plan Is a webpage particular, composed report that distinguishes potential wellsprings of tempest water contamination Describes practices to decrease poisons in tempest water releases from the website

Sediment Control BMPs Captures residue that is moved by tempest water before it leaves site Usually these are your edge controls Examples: sediment fencing, fiber moves, dregs bowls

Slide 22

Gaps in scope Silt fencing stops

Slide 38

Good cases of solid washout stations

Slide 39

Implement Good Housekeeping BMPs

Slide 40

#5 – Routine reviews not normal

Slide 41

Site examinations must be played out at regular intervals According to the 2008 CGP…

Slide 42

Site assessments must be played out like clockwork or inside 24-hrs of a rain occasion if the site gets a ½-inch or a greater amount of rain According to the 2008 CGP…

Site investigations must be played out like clockwork or inside 24-hrs of a rain occasion if the site gets a ½-inch or a greater amount of rain Must be performed by qualified staff, that would someone say someone is, learned about BMPs and tempest water administration According to the 2008 CGP…

Slide 44

Site examinations must be played out like clockwork or inside 24-hrs of a rain occasion if the site gets a ½-inch or a greater amount of rain Must be performed by qualified work force, that would someone say someone is, proficient about BMPs and tempest water administration An investigation report for each investigation must be kept in sequential request in the SWPPP According to the 2008 CGP…
