Question #12- Is there a standard Notice of Intent NOI) form that can be
submitted to EPA?
Answer - Yes. EPA has established a standard one page NOI form that is
available from EPA.
Answer - The storm water pollution prevention plan is considered the most
important requirement of the general permit. This is the plan that will be
implemented on the construction job site to bring the site into compliance
with the general permit. Each construction site covered by the general
permit must develop a plan tailored to site specific conditions and
designed with the goal of controlling the amount of pollutants in storm
water discharges from the site.
Question #14 - What information should be included in the storm water
pollution prevention plan?
Answer - The permit requires that the plan contain a site description and a
description of the measures and controls to prevent or minimize pollution
of storm water as follows:
Site Description
A description of the nature of the construction activity
A sequence of major construction activities
An estimate of the total area of the site and of the area to
disturbed
An estimate of the runoff coefficient of the site after
construction is complete
Any existing data on the quality of storm water discharge from
the site
The name of the receiving water
Any information on the type of soils at the site
A site map indicating drainage patterns and slopes after grading
activities are complete, areas of soil disturbance, the outline of
the area to be disturbed, the location of stabilization measures
and controls, and surface waters at the discharge points.
Measures and controls to prevent or minimize pollution of storm water must
include the following: erosion and sediment controls, storm water
management controls and other controls as follows:
Erosion and Sediment Controls
Stabilization (seeding, mulching, etc.) - Disturbed areas where
construction has permanently or temporarily ceased must be stabilized
within 14 days of the last disturbance or as soon as practicable in
semi-arid and arid areas. (Areas which will be re-disturbed within 21
days do not have to be stabilized).
