Design objective for stormwater control: ANSWER Reduce the amount of
contaminants released into stormwater.
ANSWER for SW control design factors Predicted precipitation quantity and
frequency, soil type and range, flow from impermeable surfaces, slopes, and
BMPs to regulate flow rates.
Requirements for sediment and erosion control: ANSWER For discharges to
any receiving waters within 50 feet of the site's earth disturbances, provide and
maintain natural buffers and/or comparable erosion and sediment controls.
Stormwater direction - ANSWER Increase infiltration and filtering in vegetated
regions to reduce pollution discharges, unless geological considerations (karst
geology, GW contamination, etc.) make it impractical.
Setting up perimeter security measures - ANSWER It must be positioned above
any natural buffers and extend along a slope's contour, with the ends bent
upward.
Keeping perimeter controls in place: ANSWER Extend or repair controls if they
are ineffective after a precipitation event, and remove sediment before it has
collected to half the height of the control.
Reducing the amount of sediment track-out limiting the use of vehicles to
specific locations and putting in tracking devices such as 3-inch gravel, rumble
plates, and wheel washing.
Handling Stockpiles: A Solution Install a sediment barrier along downgradient
areas, away from inlets or locations with concentrated flow, and provide cover
if not used for more than 14 days.
Reducing dust—ANSWER Use water or other suppression methods on exposed
soil areas.
, Factors related to soil health: ANSWER Reduce soil compaction, protect native
topsoil unless it is impractical, and reduce disruptions to steep slopes.
ANSWER: Inlet protection If a site has a sediment trap system, it is not
necessary to install protection measures that remove sediment from discharges
before entry. As sediment builds up, protections should be cleaned or replaced.
Use and storage of chemicals: ANSWER must be suitable for the type of soil
and discharges that have been treated. must be kept in storm-resistant coverings,
in leak-proof containers, and encircled by secondary containment.
Soil exposed: ANSWER It needs to be stable and erosion-resistant.
Timeline: Start stabilizing at 5 acres or fewer, where activity ceases
permanently or for more than 14 days right away, but not for more than 14 days.
Over five acres—start stabilizing when activity ceases permanently or for more
than fourteen days right away, but no more than seven days.
Monitoring turbidity—dewatering—ANSWER Every day that a dewatering
discharge occurs, as well as after it has been treated, a sample must be taken.
Benchmark for turbidity: ANSWER 50 NTUs
Frequency of inspection: ANSWER At least once every seven days, or once
every fourteen days AND within twenty-four hours of a storm event that results
in at least 0.25 inches of precipitation.
General requirements for inspections ANSWER: Verify that all stormwater
controls are installed correctly and operating as intended.
Verify whether any circumstances exist that can cause spills, leaks, or other
pollutant buildups at the location.
Determine whether any areas require updated or new stormwater controls.
Examine the areas of outflow for visible erosion and sedimentation.
ANSWER: Corrective action When a stormwater control system requires a
major repair or replacement, it is activated.
A stormwater control system that was required by the permit was either never
installed or installed incorrectly.
Water quality standards are not being met by discharges.
Contamination is clearly present.
- Etc.
ANSWER Stormwater team, construction activities, site map, non-stormwater
