Set up your BMPs before winter
starts!
The construction season is coming
to a close. Set up erosion and sediment control measures on your site before
the ground freezes, so they offer protection during winter thaws, rain events,
and the spring snow melt. Don’t risk water quality violations!

Stabilize all exposed soils
with mulch or other cover and plant seed for early spring.

Remove
sediment deltas.

 |
 |
Stabilize ditch bottoms with
appropriate BMPs.

Clean
sediment traps.
|

 |
Clean sediment from streets and
gutter systems.

Repair
non-functioning BMPs

Operating in frozen conditions
If construction work is suspended
due to frozen conditions, the site inspections can be suspended too. However,
if snow melt or precipitation causes runoff during the winter months, the
inspection and maintenance schedule must resume within 24 hours after the
runoff occurs. If construction resumes during frozen conditions, inspections
must resume 24 hours prior to resuming the construction and continue while
construction is active. Install erosion and sediment control measures on the
same timelines required during non-frozen conditions, but the installation
method and type of BMPs may change. For example, hydro mulches can’t be used on
snow, but straw mulch can. Instead of staking and trenching in silt fence, use
weights to adhere it to the ground or use rock logs as perimeter control.
