Stormwater Pollution Prevention Plan
The Stormwater Pollution Prevention Plan (SWPPP) is a document
prepared by a qualified engineer which is used to plan the
stormwater related erosion control program for California
construction sites greater than 1 acre in size. The SWPPP
document follows a standardized template layed out by the EPA.
While all sections are important, Section 500 of the document is
where the majority of the engineer’s work is found and is used
to cover specific plans regarding potential pollutant sources
and how they are to be kept out of the stormwater systems.
Advanced Civil Group is ready to assist your SWPPP needs in the
following ways:
1. SWPPP Preparation
2. SWPPP Training to your Staff
3. BMP Implementation
4. Construction Site Monitoring Program
The Only Thing in the Drain should be the Rain
The SWPPP is the plan of action to keep construction related
dirt, silt, chemicals, and other undesirables out of the storm
drain system and out of nearby natural water systems. This is
done by a careful analysis of your land, construction plans,
rain seasons, and other factors which may effect the run off of
water from your construction site. As construction begins, the
vegetation that keeps the dirt attached to the ground is broken
up. When this happens, the amount of dirt collected in the water
from a rainstorm increases 1000 times. As dirty water enters the
storm drain systems, it pollutes rivers, streams, and the
general eco-system that we live in. By running a successful
SWPPP, not only are you reducing the risk of huge fines, you are
also saving your environment for you and for future generations.
It is a good cause.
Best Management Practices
Part of the implementation of the SWPPP is done by the use of
what the industry terms as “Best Management Practices” or BMPs.
Best Management Practices refer to the proper use of defensive
mechanisms designed to reduce erosion during rain storms. Below
is a list of the most commonly used approaches. When used in
layers, these practices have proven to be very effective at
reducing stormwater erosion. Nevertheless, close monitoring is
mandatory when the rain is coming down to ensure that these
preventive measures are properly doing the job.
Sandbag Berms
Gravel Bags
Silt Fences
Fiber Rolls
Erosion Control Blankets
Hydro Seeding
Mulching
Proper Construction Entrances
Compliance
Once your plan is in action, the work is not done. BMP’s must be
maintained. Sampling may be required. Reporting during the storm
events must be done properly and accurately. This is when the
local inspectors tend to really get involved. As long as you are
doing all that you are required to do, the inspectors are more
likely to work with you in a positive way as you do your share
to save the environment. Make certain you are prepared by doing
it right the first time.

EPA's new resource:
Developing Your Stormwater Pollution Prevention Plan—A Guide for
Construction Sites
(Jan. 2007)
A stormwater pollution prevention plan (SWPPP) is a fundamental
requirement of stormwater permits. A SWPPP:
identifies all potential sources of pollution which may
reasonably be expected to affect the quality of storm water
discharges from the construction site
describes practices to be used to reduce pollutants in storm
water discharges from the construction site, and
helps assure compliance with the terms and conditions
of the permit (when the plan is designed for the individual
site, and is fully implemented)
SWPPP requirements vary somewhat from state to state, although
there are fewer differences now than a few years ago because
states are adopting the federal SWPPP requirements. The
requirements for each state are spelled out in the stormwater
permit issued by your state agency. The Stormwater Resource
Locator (SWRL) provides information on the SWPPP requirements
for each individual state.
EPA published Developing Your Stormwater Pollution Prevention
Plan: A Guide for Construction Sites in May 2007. This “SWPPP
Guide” contains detailed information on developing and
implementing a construction site SWPPP. It also contains a
customizable SWPPP Template and a sample Inspection Form (both
in Microsoft Word). EPA’s website also includes two “model or
example” SWPPPs that have been completed for two hypothetical
construction sites.
The EPA SWPPP Guide is designed to be used nationwide, in any
state, territory or Indian land, in conjunction with the
applicable state or EPA NPDES Construction General Permit. To
find your NPDES permitting authority and the applicable
Construction General Permit, see www.epa.gov/npdes/stormwater/authorizationstatus or
Stormwater Resource Locator. The Stormwater Resource Locator
also will help you identify other applicable federal, state,
tribal or local erosion and sediment control and stormwater
management requirements.
Download and print the SWPPP Guide at www.epa.gov/npdes/swpppguide,
where you’ll also find the SWPPP Template and sample Inspection
Form, and example SWPPPs. For printed copies, please contact
EPA’s publications warehouse (National Service Center for
Environmental Publications) at 1-800-490-9198 or nscep@bps-lmit.com and
reference the EPA document control number (EPA 833-R-06-004) in
your request. |
