3. CHARACTERIZATION OF PROJECT RUNOFF
According to the California 2002 303d list published by the San Diego Regional Water
Quality Control Board, there is one impaired water body within the Carlsbad
Watershed, Agua Hedionda Subarea, including Agua Lagoon Creek and the Agua
Hedionda Lagoon. The Agua Hedionda Lagoon is located approximately 2 miles
downstream from the project site.
The project location and watersheds have been compared to the current
published 303d list of impaired water bodies and the nearest impaired
water body is the Pacific Ocean at the Buena Vista Lagoon, impaired by
bacteria indicators generated by non-point/point source pollution.
Education materials included in this SWMP and in the Attachments will be
distributed by the project owners and will limit pollution by limiting
exposure of these pollutants to the storm water runoff.
EXPECTED DISCHARGES
There are no sampling data available for the existing site condition. In addition, the
project is not expected to generate significant amounts of non-visible pollutants.
However, the following constituents are commonly found on similar developments and
could affect water quality:
Sediment discharge due to construction activities and post-construction
areas left bare.
Nutrients from fertilizers
Hydrocarbons from paved areas.
Pesticides from landscaping and home use.

4. POLLUTANTS/CONSTITUENTS OF CONCERN
The project locations and watersheds have been compared to the current published
303d list of impaired water bodies. The Agua Hedionda, Buena Vista Lagoon, and San
Elijo Lagoons are experiencing impairments to beneficial uses due to excessive coliform
bacteria (bacteria indicators), nutrients and sedimentation/siltation, as well as trace
metal and toxics from upstream sources. These coastal lagoons represent critical
regional resources that provide freshwater and estuarine habitats for numerous plant
and animal species.
The primary constituents of concern are coliform, nutrients, and sediment.
The sources and activities contributing to the impairments in this area are Urban runoff,
agricultural runoff, sewage spills, and livestock / domestic animals. Coliform bacteria is
generated by fecal material from human and animal waste released in sewage spills.
This project is not likely to produce this constituent of concern. The Secondary
Pollutants of concern are trace minerals and toxins. Possible pollutants found on this
site may include:
a) Wash down water from Asphalt
b) Hydrocarbons from pavement surfaces
c) Sediment from Construction Activities
The following section will outline the Best Management Practices that will provide for the
protection of the water quality, with respect to the Possible pollutants of concern that
may be generated by this project.
5. MITIGATION MEASURES TO PROTECT WATER QUALITY
BEST MANAGEMENT PRACTICES (BMP)
According to the Model Standard Urban Stormwater Mitigation Plan for City of
Carlsbad (SUSMP). approved bv the San Diego County Regional Water Quality
Control Board June 12. 2002. residential subdivisions with more than 5000 s.f. of
paving are considered "priority projects" and therefore have certain storm water
mitigation design requirements. The following is a list of those requirements:
Private Roads/Paving shall include the following:
a) Rural swale system: Street sheet flows to vegetated swale or
gravel shoulder, curbs at street corners, culverts under
driveways and street crossings;
b) Urban curb/swale system street slopes to curb, periodic
swale inlets drain to vegetated swale/biofilter;
c) Dual drainage system; First flush captured in street catch
d)
basins and discharged to adjacent vegetated swale or gravel
shoulder, high flows connect directly to storm water
conveyance system;
Other features which are comparable and equally effective
Best Management Practices (BMPs) are intended to provide measures which minimize
or eliminate the introduction of pollutants into the storm water system. All constituents
of concern will be removed from the storm water runoff to minimize impact of
development on impaired water bodies.
5.1 Construction BMPs
To address water quality for the project, BMPs will be implemented during construction
and post-construction. The construction activities are dual regulated by the California
Statewide General Construction Permit and San Diego County Ordinances.

Site Design BMPs
This project was designed to minimize, to the maximum extent practical, the introduction
of pollutants and conditions of concern that may result in significant impacts to the storm
water conveyance system. Site Design BMPs are designed to maintain pre-
development runoff characteristics. The following concepts were applied to this project
in the following manner:
1) Minimize impervious footprint
1) Increase building density
2) Construct Walkways, trails, patios, overflow parking lots and alleys, and other
low-traffic areas with permeable surfaces, such as pervious concrete, porous
asphalt, unit pavers, and granular materials;
3) construct streets, sidewalks, and parking aisles to the minimum widths
necessary, provided that public safety and walkable environment for pedestrians
are not compromised; and
4) minimize the use of impervious surfaces, such as decorative concrete, in the
landscape design.
The project has been designed to minimize length of driveways as house pads have
been located as close to the new street as is possible. Streets and sidewalks have
been designed to the minimum widths allowable.
2) Conserve natural area.
1) Concentrate or cluster development on the least environmentally sensitive
portions of a site while leaving the remaining land in a natural undisturbed
condition.
2) Use natural drainage systems to the maximum extent practicable.
This project involves the grading of the entire site so no vegetation will able to be
conserved. However, an extensive landscape design will provide natural infiltration to
the maximum extent practicable.
11
3) Minimize directly connected Impervious Area.
This was not possible. Impervious areas are streets and must be connected. However,
wherever possible landscape areas are provided.
4) Maximize canopy interception and water conservation.
1) Preserve existing native trees and shrubs; and
2) Plant additional native or drought tolerant trees and large shrubs in place of
non-drought tolerant exotics.
Landscape plan calls for native tree and shrubs.
5) Convey runoff safely from the tops of slopes.
A brow ditch will be installed to convey runoff safely from the tops of slopes.
6) Vegetate slopes with native or drought tolerant vegetation.
All slopes will be vegetated as soon as is practical after grading is complete.
7) Stabilize permanent channel crossings.
Not-applicable - No channel crossings.
8) Install energy dissipaters, such as rip-rap, at the outlets of new storm drains, culverts,
conduits, or channels that enter unlined channels in accordance with applicable
specifications to minimize impacts to receiving waters.
Not-applicable - There are no unlined channels in this project.
Source Control (Non-structural) BMPs include education, clean-up and facility
maintenance to prevent pollutants from entering the storm water system. Treatment
Control BMPs are facilities designed to remove pollutants of concern from the storm
water conveyance system to the maximum extent practicable through the incorporation
of treatment control BMPs.
The following is a specific list of suggested BMP's for this project and discussion of their
effectiveness.
Source Control (Non-Structural) BMPs
(N1) Owner Education -The Project Owner will educate employees and tenants
of general good housekeeping practices that contribute to the protection of storm
water quality by providing information on Best Management Practices. (See All
Attachments)
12
(N2) Activity Restrictions - All activities will comply with Order 2001-01. Waste
Discharge Requirements of the Urban Runoff from the Municipal Separate Storm
Sewer Systems (MS-4) Regulations, and the City of Carlsbad's Municipal Code
and Zoning Ordinance. Specific restrictions of the site will include, but are not
limited to, the following:
• No Hosing of Paved Area - Parking surfaces and driveways will not be
cleaned by "hosing down", but will instead be swept clean or vacuumed,
with collected waste disposed of in a covered container. Oil stains will not
be cleaned via an acid wash of the driveway. Instead, oil stains and leaks
will cleaned using rags or absorbents, then swept using granular solvent
material, and finally mopped. Mop water shall be disposed of into a
sanitary sewer facility.
• Trash - No rubbish, trash, garbage or other waste material shall be kept on-
site or on any public street abutting the properties, except in sanitary
container located in appropriate areas (trash containers).
• Drainage - There shall be no interference with or alteration of the
established drainage pattern on the site unless an adequate alternative
provision is made for proper drainage with the prior written approval of the
City.
Outside Storage - Storage of materials will not be allowed outside the main
buildings unless authorized by the governing agencies. A revised SWMP
will be issued in this event detailing the BMPs associated with outdoor
storage.
• Pet Waste - Pet waste will be disposed of in trash containers or sewers and
not be allowed in public gutters.
(N3) BMP Maintenance - Owner shall assign a person who will be responsible for
implementation of each non-structural BMP and scheduled cleaning of all structural
BMP facilities. (See Section 5.)
(N4) Local Industrial Permit Compliance - Owners will be responsible for
relaying requirements to any future owner.
(N5) Spill Contingency Plan - Owners shall provide and implement a spill
contingency plan if Hazardous Wastes are known to be stored on property See
WM-4. (Attached).
(N6) Common Area Litter Control - Owners shall implement a trash management
and litter control program for the reduction of off site migration of trash. Owners
and Tenants will be responsible for having the site inspected twice a week and
cleaned as necessary.
13
(N7) Owner Training - Owners will periodically provide information to owners and
tenants from this document and other Agencies of good housekeeping practices
that contribute to the protection of storm water quality. This education will address,
but is not limited to the use and storage of chemicals, pesticides, BMPs regarding
site cleanup, litter control and trash collection. (See all Attachments.)
(N8) Common Area Catch Basin Inspection - Owners will inspect and clean
catch basins on a regular basis. All filters will be replaced per guidelines
established by the manufacturer. (See Table 6.1)
(N9) Common Area Efficient Irrigation - Irrigation shall be implemented as
indicated on the City approved Landscape Plans and be consistent with City water
conservation resolution. This shall include programmable irrigation and run-off
minimizing landscaping.
(N10) Common Area Runoff-Minimizing Landscape Design - Plants with similar
water requirements shall be grouped in order to minimize the amount of excess
water flow. See NS-1 & NS-7 (attached).
(N11) Catch Basin Stenciling - Phrase "No Dumping - Drains to Ocean" to be
stenciled on catch basin and curb inlet to alert the public to the destination of
pollutants discharged into storm water.
Treatment Control (Structural) BMPs
Flow based BMPs will be designed to mitigate (infiltrate, filter or treat) the flow of runoff
produced from rainfall intensity of 0.2 in/hr. The Flow is calculated as:
Impervious Surfaces
Flow based calculation:
Q = C I A Q = allowable Q
I = 0.2 in/hr
Basin A
A = Impervious Surface = 10,039 s.f./43560 = 0.23 ac
Basin B
A= Impervious Surface = 20,582 s.f./43560 = 0.47 ac
C = coefficient of runoff = 1.0
Basin A: Q = C IA = 1.0 (0.2) (.23) = .043 cfs
Basin B: Q = C IA = 1.0 (0.2) (.47) * .094 cfs
Q allowable for the specified inserts is 1.6 cfs.
Catch basin inserts will be installed in all proposed and existing catch basins designed to
14
capture all pollutants and constituents of concern. See Attachment "B" for specifications
of this Treatment BMPs.
(S1) Water Quality Inlets - Curb Inlet with Baskets - Runoff from the streets and
roof tops will be directed to proposed inlet structures within the existing curb face.
See Site Plan.
The basket is designed to capture contaminants that normally enter inlets during
low to medium flow and does not inhibit flow during high flow storm water runoff
events. The specified inlet shall be installed to factory specification and
maintained by the owners. The specified inlet is appropriate for removing all
pollutants of concern from the runoff. (See Attachment "B").
Curb Inlet Baskets are easy to maintain and capture debris such as trash and
weeds as well as non-visible pollutants, such as hydrocarbons and fertilizers.
Efficiency: Likely to have a significant impact on Sediment and Non-visible
pollutants.
15
6. MAINTENANCE STORMWATER MANAGEMENT PROGRAM
Pollution Prevention BMPs (MEP based): The developer of the office building will be
responsible for developing a plan to educate new employees regarding limiting exposure
of pollutants to storm water. This plan will include education regarding proper use and
disposal of pollutants and a plan for Spill Cleanup procedures and may include all
Attachments included in this SWMP.
Maintenance Responsibility: All BMPs and erosion control devices shall be maintained,
repaired and replaced as needed by the Owner. The operation and maintenance
requirements for post-construction BMPs are shown in Table 6.1

Note that the Initial Time of Concentration should be reflective of the general land-use at the
upstream end of a drainage basin. A single lot with an area of two or less acres does not have
a significant effect where the drainage basin area is 20 to 600 acres.
Table 3-2 provides limits of the length (Maximum Length (LM))^of sheet flow to be used in
hydrology studies. Initial Tj values based on average C values for the Land Use Element are
also included. These values can be used in planning and design applications as described
below. Exceptions may be approved by the "Regulating Agency" when submitted with a
detailed study.

ABOUT URBAN AND STORM WATER RUNOFF...
Urban and storm water runoff is a serious concern, in both dry and rainy
season. It is contaminated with pesticides, fertilizers, animal droppings,
trash, food wastes, automotive byproducts and other toxic substances
that are part of our urban environment Waters that flow over streets,
parking lots, construction sites and industrial facilities carry these
pollutants through a 5,000-mile storm drain network directly to the lakes,
streams and beaches of Southern California.
Urban runoff is the largest source of unregulated pollution to the
waterways and coastal areas of the United States. Locally, we see the
impacts in increased health risks to swimmers near storm drains, high
concentrations of toxic metals in harbor and ocean sediments, and
toxicity to aquatic life.
These impacts translate into losses to the County's $2 billion a year
tourism economy, loss of recreational resource, dramatic cost increases
for cleaning up contaminated sediments and impaired function and
vitality of our natural resources.
HISTORY
The Clean Water Act of 1987 established requirements for storm water
discharges under the National Pollutant Discharge Elimination System
NPDES) program. In response to those requirements, the State of
California issued a five-year permit for municipal storm water discharges
to Los Angeles County in June 1990.
The 1990 permit was very general in nature, resulting in storm water
programs that varied widely from city to city. The 1996 permit, a
reissuance of the 1990 permit, therefore seeks to provide better direction
by specifying actions needed to comply with permit requirements.
This permit is the result of one and a half years of discussions between
representatives of the Los Angeles Regional Water Quality Control
Board (Regional Board), Los Angeles County, the City of Los Angeles,
three smaller cities, and the environmental community. It also
incorporates extensive comments received from all interested parties on
two earlier drafts.
GOALS OF THE MUNICIPAL STORM WATER PERMIT
• To attain and protect the beneficial uses of water bodies in Los
Angeles County;
• To reduce pollutants in stormwater to the maximum extent

NPDES Permit "Lite" for the Non-Technical Reader
• To evaluate compliance with the objectives and requirements
contained in the permit.
REQUIREMENTS OF THE STORM WATER MANAGEMENT
PROGRAM
In general, the permit requires implementation of both the Storm Water
Management Program contained in the permit, the elements of the
Countywide Stormwater Management Plan (CSWMP) or Watershed
Management Area Plans (WMAP) that will be developed pursuant to the
permit
The Countywide Storm Water Management Plan
and Water Management Area Plans
Much of the permit details the Storm Water Management Program
elements and "what" should be induded in the CSWMP. Developing the
specified program elements will require that Permittees determine "how"
actions will be implemented. Program elements, once developed, will
then be compiled into the unified implementation plan known as the
CSWMP.
The Watershed Management Area Plans are to be devdoped later in the
permit cycle. They are based on the requirements of the permit and the
"iSWMP, but will also indude actions that address water quality problems
• tnd concerns that are unique to the six watershed areas of Los Angeles
Jounty. Once developed and approved, the WMAP superceded the
CSWMP.
The storm water management program is comprised of seven elements,
the objectives of which are to:
1. Effectively manage and coordinate implementation of the storm
water program;
2. Identify and eliminate illicit connections and illicit discharges to the
storm drain system;
3. Reduce storm water impacts associated with development and
redevelopment projects;
4. Reduce storm water quality impacts associated with public agency
activities;
5. Increase public knowledge about the impacts of storm water
pollution and about actions that can be taken to prevent pollution.
6. Increase knowledge and understanding about the quality,
quantity, sources, and impacts of urban runoff; and
7. Evaluate the effectiveness of implementing storm water
management programs.

GENERAL CATAGORIES FOR WATER POLLUTION
Urban runoff from a developed site has the potential to contribute pollutants, including oil and
grease, suspended solids, metals, gasoline, pesticides, and pathogens to the storm water
conveyance system and receiving waters. For the purposes of identifying pollutants of concern
and associated storm water BMPs, pollutants are grouped in nine general categories as follows:
1. Sediments -Sediments are soils or other surficial materials eroded and then
transported or deposited by the action of wind, water, ice, or gravity. Sediments can increase
turbidity, clog fish gills, reduce spawning habitat, lower young aquatic organisms survival rates,
smother bottom dwelling organisms, and suppress aquatic vegetation growth.
2. Nutrients- Nutrients are inorganic substances, such as nitrogen and phosphorus. They
commonly exist in the form of mineral salts that are either dissolved or suspended in water.
Primary sources of nutrients in urban runoff are fertilizers and eroded soils. Excessive discharge
of nutrients to water bodies and streams can cause excessive aquatic algae and plant growth. Such
excessive production, referred to as cultural eutrophication, may lead to excessive decay of
organic matter in the water body, loss of oxygen in the water, release of toxins in sediment, and
the eventual death of aquatic organisms.
3. Metals -Metals are raw material components in non-metal products such as fuels, adhesives,
paints, and other coatings. Primary source of metal pollution in storm water are typically
commercially available metals and metal products.
Metals of concern include cadmium, chromium, copper, lead, mercury, and zinc. Lead and
chromium have been used as corrosion inhibitors in primer coatings and cooling tower systems.
At low concentrations naturally occurring in soil, metals are not toxic. However, at higher
concentrations, certain metals can be toxic to aquaticlife. Humans can be impacted from
contaminated groundwater resources, and bioaccumulation of metals in fish and shellfish.
Environmental concerns, regarding the potential for release of metals to the environment, have
already led to restricted metal usage in certain applications.
4. Organic Compounds -Organic compounds are carbon-based. Commercially available or
naturally occurring organic compounds are found in pesticides, solvents, and hydrocarbons.
Organic compounds can, at certain concentrations, indirectly or directly constitute a hazard to life
or health. When rinsing off objects, toxic levels of solvents and cleaning compounds can be
discharged to storm drains. Dirt, grease, and grime retained in the cleaning fluid or rinse water
may also adsorb levels of organic compounds that are harmful or hazardous to aquatic life.
5. Trash & Debris -Trash (such as paper, plastic, polystyrene packing foam, and aluminum
materials) and biodegradable organic matter (such as leaves, grass cuttings, and food waste) are
general waste products on the landscape. The presence of trash & debris may have a significant
impact on the recreational value of a water body and aquatic habitat Excess organic matter can
create a high biochemical oxygen demand in a stream and thereby lower its water quality. Also, in
areas where stagnant water exists, the presence of excess organic matter can promote septic
conditions resulting in the growth of undesirable organisms and the release of odorous and
hazardous compounds such as hydrogen sulfide.
6. Oxygen-Demanding Substances - This category includes biodegradable organic material as
well as chemicals that react with dissolved oxygen in water to form other compounds. Proteins,
carbohydrates, and fats are examples of biodegradable organic compounds. Compounds such as
ammonia and hydrogen sulfide are examples of oxygen-demanding compounds. The oxygen
demand of a substance can lead to depletion of dissolved oxygen in a water body and possibly the
development of septic conditions.
7. Oil and Grease - Oil and grease are characterized as high-molecular weight organic
compounds. Primary sources of oil and grease are petroleum hydrocarbon products, motor
products from leaking vehicles, esters, oils, fats, waxes, and highmolecular-weight fattyacids.
Introduction of these pollutants to the water bodies are very possible due to the wide uses and
applications of some of these products in municipal, residential, commercial, industrial, and
construction areas. Elevated oil and grease content can decrease the aesthetic value of the water
body, as well as the water quality.
8. Bacteria and Viruses - Bacteria and viruses are ubiquitous microorganisms that thrive under
certain environmental conditions. Their proliferation is typically caused by the transport of animal
or human fecal wastes from the watershed. Water, containing excessive bacteria and viruses can
alter the aquatic habitat and create a harmful environment for humans and aquatic life. Also, the
decomposition of excess organic waste causes increased growth of undesirable organisms in the
water.
9. Pesticides - Pesticides (including herbicides) are chemical compounds commonly used to
control nuisance growth or prevalence of organisms. Excessive application of a pesticide may
result in runoff containing toxic levels of its active component.

Nonpoint Source Pollution: The Nation's Largest Water Quality
Problem
Why is there still water that's too dirty for swimming, fishing or
drinking? Why are native species of plants and animals disappearing
from many rivers, lakes, and coastal waters?
The United States has made tremendous advances in the past 25 years
to clean up the aquatic environment by controlling pollution from
industries and sewage treatment plants. Unfortunately, we did not do
enough to control pollution from diffuse, or nonpoint, sources. Today,
nonpoint source (NFS) pollution remains the Nation's largest source of
water quality problems. It's the main reason that approximately 40
percent of our surveyed rivers, lakes, and estuaries are not clean
enough to meet basic uses such as fishing or swimming.
NFS pollution occurs when rainfall, snowmelt, or irrigation runs over
land or through the ground, picks up pollutants, and deposits them into
rivers, lakes, and coastal waters or introduces them into ground water.
Imagine the path taken by a drop of rain from the time it hits the
ground to when it reaches a river, ground water, or the ocean. Any
pollutant it picks up on its journey can become part of the NFS
problem. NFS pollution also includes adverse changes to the
vegetation, shape, and flow of streams and other aquatic systems.
NFS pollution is widespread because it can occur any time activities
disturb the land or water. Agriculture, forestry, grazing, septic systems,
recreational boating, urban runoff, construction, physical changes to
stream channels, and habitat degradation are potential sources of NFS
pollution. Careless or uninformed household management also
contributes to NFS pollution problems.
The latest National Water Quality Inventory indicates that agriculture
is the leading contributor to water quality impairments, degrading 60
percent of the impaired river miles and half of the impaired lake acreage
surveyed by states, territories, and tribes. Runoff from urban areas is the largest source of water quality
impairments to surveyed estuaries (areas near the coast where seawater mixes with freshwater).
The most common NFS pollutants are sediment and nutrients. These wash into water bodies from
agricultural land, small and medium-sized animal feeding operations, construction sites, and other areas
of disturbance. Other common NFS pollutants include pesticides, pathogens (bacteria and viruses),
salts, oil, grease, toxic chemicals, and heavy metals. Beach closures, destroyed habitat, unsafe drinking
water, fish kills, and many other severe environmental and human health problems result from NFS
pollutants. The pollutants also ruin the beauty of healthy, clean water habitats. Each year the United
States spends minions of dollars to restore and protect the areas damaged by NFS pollutants.

Nonpoint Source Pollution: The Nation's Largest Water (Duality rrooieiu
Progress
During the last 10 years, our country has made significant headway in addressing NFS pollution. At the
federal level, recent NFS control programs include the Nonpoint Source Management Program
established by the 1987 Clean Water Act Amendments, and the Coastal Nonpoint Pollution Program
established by the 1990 Coastal Zone Act Reauthorization Amendments. Other recent federal
programs, as well as state, territorial, tribal and local programs also tackle NPS problems.
In addition, public and private groups have developed and used pollution prevention and pollution
reduction initiatives and NPS pollution controls, known as management measures, to clean up our
water efficiently. Water quality monitoring and environmental education activities supported by
government agencies, tribes, industry, volunteer groups, and schools have provided information about
NPS pollution and have helped to determine the effectiveness of management techniques.
Also, use of the watershed approach has helped communities address water quality problems caused by
NPS pollution. The watershed approach looks at not only a water body but also the entire area that
drains into it. This allows communities to focus resources on a watersheds most serious environmental
problems—which, in many instances, are caused by NPS pollution.
Just as important, more citizens are practicing water conservation and participating in stream walks,
beach cleanups, and other environmental activities sponsored by community-based organizations. By
helping out in such efforts, citizens address the Nation's largest water quality problem, and ensure that
even more of our rivers, lakes, and coastal waters become safe for swimming., fishing, drinking, and
aquatic life.

Opportunities for Public Involvement in Nonpoint source
Pointer No. 2
EPA841-F-96-004B
Did you know
that volunteers
often collect
information on the
health of water-
ways and the
extent of NFS
pollution?
Opportunities for Public Involvement in Nonpoint Source Control
Over the last 25 years, communities have played an important role in
addressing nonpoint source (NPS) pollution, the Nation's leading source
of water quality problems. When coordinated with federal, state, and
local environmental programs and initiatives, community-based NPS
control efforts can be highly successful. To learn about and help control
NPS pollution, contact the community-based organizations and
environmental agencies in your area. These groups often have
information about how citizens can get involved in the following types
of NPS control activities.
£ Volunteer Monitoring
Local groups organize volunteers of all skill levels to gather water
quality data. This information can help government agencies understand
the magnitude of NPS pollution. More than 500 active volunteer
monitoring groups currently operate throughout the United States.
Monitoring groups may also have information about other NPS
pollution projects, such as beach cleanups, stream walks, and
restoration activities.
Ecological Restoration
Ecological restoration provides opportunities for the public to help out
with a wide variety of projects, such as tree planting and bank
stabilization in both urban and rural areas. Restoration efforts focus on
degraded waters or habitats that have significant economic or ecological
value.
Educational Activities
NPS pollution occurs when
water runs over land or through
the ground, picks up pollutants,
and deposits them in surface
waters or introduces them into
groundwater.
Teachers can integrate NPS pollution curricula into their classroom
activities. The U.S. Environmental Protection Agency (EPA), federal
and state agencies, private groups, and nonprofit organizations offer
teachers a wide variety of materials. Students can start on an NPS
control project in the primary grades and carry their work through to
the intermediate and secondary levels.
Water Conservation
Using technologies that limit water use in the bathroom, kitchen, laundry room, lawn, driveway, and
garden can reduce the demand on existing water supplies and limit the amount of water runoff. More
than 40 states now have some type of water conservation program to help citizens and businesses
implement conservation practices. Government agencies, utilities, and hardware stores have
information about different products that help households conserve water.

Opportunities for Public Involvement in Monpouii source
Household Management
Learning to limit NFS pollution at the household level can reduce the overall impacts of NFS pollution
on water quality. Households, for example, can irrigate during cooler hours of the day, limit fertilizer
applications to lawns and gardens, and properly store chemicals to reduce runoff and keep runoff clean.
Chemicals and oil should not be poured into sewers, where they can result in major water quality
problems. Pet wastes, a significant source of nutrient contamination, should be disposed of properly.
Households can also replace impervious surfaces with more porous materials.
Public Meetings and Hearings
Decisions made during public hearings on stormwater permitting and town planning can determine a
community's capability to manage NPS pollution over the long term. Laws or regulations may require
federal, state, or local agencies to hold public hearings when permits are issued or when town plans are
formed. Notices about hearings often appear in the newspaper or in government office buildings.
Community Organizations
Many communities have formed groups to protect local natural resources. These community-based
groups provide citizens with information about upcoming environmental events in their watershed,
such as ecological restoration, volunteer monitoring, and public meetings. Watershed-level associations
are particularly effective at addressing a wide range of NPS pollution problems.
Environmental Information on the Internet
Citizens can obtain a tremendous amount of environmental data and educational material with a
computer linked to the World Wide Web. EPA's site (http://www.epa.gov) on the World Wide Web
provides up-to-date information on Agency activities and enables citizens to find out about air and
water quality data in specific communities.
EPA supports NPSINFO, a forum for discussion of NPS issues, including NPS education. Citizens
with access to e-mail can subscribe to NPSINFO free of charge by sending an e-mail message to:
Ustserver@unixmail.rtpnc.epa.gov
and include in the body of the message:
subscribe NPSINFO (your first name) (your last name)
Other federal, state, tribal, and local agencies, as well as businesses and nonprofit groups, also provide
environmental information on the World Wide Web.

Pointer No. 4
EPA841-F-96-004D
Did you know
that at least 50%
of water quality
problems in the
U.S. result from
NFS pollution?
NPS pollution occurs when
wal er run s ove r Ian dor throu gh
the ground, picks up pollutants,
and deposits them in surface
waters or introduces them into
groundwater.
The Nonpoint Source Management Program
The Clean Water Act of 1972 helped clean up of many of our country's
waters, often achieving dramatic improvements. Despite those
successes, approximately 36 percent of the Nation's surveyed river
miles, 37 percent of its surveyed lake acreage, and 37 percent of its
;• surveyed estuarine square miles are not safe for basic uses such as
swimming or fishing.
States, territories, and tribes estimate that at least half of these
impairments, as well as significant ground water contamination, are
caused by nonpoint source (NPS) pollution, making it the Nation's
leading source of water quality problems. To address these problems,
Congress amended the Clean Water Act in 1987. Congress established
the NPS Pollution Management Program under section 319 of the
amendments. The program provides states, territories, and tribes with
grants to implement NPS pollution controls described in approved NPS
pollution management programs.
In 1990, the U.S. Environmental Protection Agency (EPA) began
awarding grants to states, territories, and tribes with approved
programs. By 1991, all 50 states and the territories had received EPA
approval; by 1995,7 tribes also had received approval. Since 1990,
recipients of 319 grants have directed approximately 40 percent of
awarded funds toward controlling NPS pollution from agricultural
lands. In addition, nearly one-quarter of the money was used for general
assistance purposes, including funding for outreach and technical
assistance. Efforts to control runoff from urban sources, septic systems,
and construction also received significant funding under section 319, as
did projects to manage wetlands and NPS pollution from forestry,
habitat degradation, and changes to stream channels.
In 1991, EPA established the National Monitoring Program to evaluate
the effectiveness of NPS pollution control projects. Fourteen state-
proposed projects will be evaluated over a 6- to 10-year period. The
findings from this effort will help states, territories, and tribes develop
more successful NPS pollution controls in other watersheds.
As of 1995, EPA had awarded states, territories, and tribes $370 million under section 319 to
implement NPS pollution control. Section 319 Success Stories provides examples of how states,
territories, and tribes chose to use section 319 funds.
How Section 319 Works
Assessment Reports
http://www.epa.gov/OWOW/NPS/facts/point4.htm 9/27/01
The Nonpoint Source Management Program
All states, territories, and some tribes "have met two basic requirements to be eligible for a section. 319
grant, the first of which is to develop and gain EPA approval of a NFS pollution assessment report. In
the assessment report, the state, territory, or tribe identifies waters impacted or threatened by NFS
pollution. The state, territory, or tribe also describes the categories of NFS pollution, such as
agriculture, urban runoff, or forestry, that are causing water quality.
Management Programs
To meet the second requirement a state, territory, or tribe must develop and obtain EPA approval of a
NPS pollution management program. This program becomes the framework for controlling NPS
pollution, given the existing and potential water quality problems described in the NPS pollution
assessment report. A well-developed management program supports activities with the greatest
potential to produce early, demonstrable water quality results; assists in the building of long-term
institutional capacity to address NPS pollution problems; and encourages strong interagency
coordination and ample opportunity for public involvement in the decision-making process.
How to Get Involved
The addresses and telephone numbers of state and territory nonpoint source officials are listed in the
Nonpoint Source Water Quality Contacts Directory. These individuals can inform citizens about
section 319 program activities in their home state or territory. They can also let citizens know how to
become involved in the periodic updates of section 319 NPS assessments and NPS management
programs.

EPA841-F-96-004E
Protecting Coastal Waters from Nonpoint Source Pollution
Coastal waters provide homes for an amazing array of plants and
animals and are recreational havens for more than 180 million visitors
each year. Yet, high levels of pollution prevented people from
swimming safely at coastal beaches on more than 12,000 occasions from
1988 through 1994, and the latest National Water Quality Inventory
reports that one-third of surveyed estuaries (areas near the coast where
seawater and freshwater mixing occurs) are damaged. Rapidly
increasing population growth and development in coastal regions could
be a source of even more coastal water quality problems in the nature.
A significant portion of the threats to coastal waters are caused by
nonpoint source pollution (NFS). Major sources in coastal waters
include agriculture and urban runoff. Other significant sources include
faulty septic systems, forestry, marinas and recreational boating,
physical changes to stream channels, and habitat degradation, especially
the destruction of wetlands and vegetated areas near streams.
In 1990, Congress passed the Coastal Zone Act Reauthorization
Amendments (CZARA) to tackle the nonpoint source pollution problem
in coastal waters. Section 6217 of CZARA requires the 29 states and
territories with approved Coastal Zone Management Programs to
develop Coastal Nonpoint Pollution Control Programs. In its program, a
state or territory describes how it will implement nonpoint source
pollution controls, known as management measures, that conform with
those described in Guidance Specifying Management Measures for
Sources of Nonpoint Pollution in Coastal Waters.
If these original management measures fail to produce the necessary
coastal water quality improvements, a state or territory then must
implement additional management measures to address remaining water
quality problems. Approved programs will update and expand upon
NPS Management Programs developed under section 319 of the Clean
Water Act and Coastal Zone Management Programs developed under
section 306 of the Coastal Zone Management Act.
The coastal nonpoint program strengthens the links between federal and state/territory coastal zone
management and water quality programs in order to enhance efforts to manage land management
activities that degrade coastal waters and coastal habitats. State and territorial coastal zone agencies
and water quality agencies have coequal roles, as do the National Oceanic and Atmospheric
Administration (NOAA) and the U.S. Environmental Protection Agency (EPA) at the federal level.
Coastal Nonpoint Pollution Control Programs

for review and approval. States and territories are scheduled to implement the first phase of their
approved program by 2004 and, if necessary, the second phase by 2009. Approved programs include
several key elements, described below.
Boundary. The boundary defines the region where land and water uses have a significant impact on a
states or territorys coastal waters. It also includes areas where future land uses reasonably can be
expected to impair coastal waters. To define the boundary, a state or territory may choose a region
suggested by NOAA or may propose its own boundary based on geologic, hydrologic, and other
scientific data.
Management Measures. The state or territory coastal nonpoint program describes how a state or
territory plans to control NFS pollution within the boundary. To help states and territories identify
appropriate technologies and tools, EPA issued Guidance Specifying Management Measures for
Sources of Nonpoint Pollution in Coastal Waters. This technical guidance describes the best available,
economically achievable approaches used to control NFS pollution from the major categories of land
management activities that can degrade coastal water quality. States or territories may elect to
implement alternative measurement measures as long as the alternative measures will achieve the same
environmental results as those described in the guidance.
Enforceable Policies and Mechanisms. States and territories need to ensure the implementation of the
management measures. Mechanisms may include, for example, permit programs, zoning, bad actor
laws, enforceable water quality standards, and general environmental laws and prohibitions. States and
territories may also use voluntary approaches like economic incentives if they are backed by
appropriate regulations.
Final Approval and Conditional Approval
In certain circumstances, NOAA and EPA may grant a program conditional approval for up to 5 years.
Conditional approval provides a state or territory additional time to fully develop its management
program while it begins initial program implementation. Conditional approval would include
benchmarks for progress toward eventual full program development and approval.

Managing Urban Runoff
Pointer No. 7
EPA841-F-96-004G
Managing Urban Runoff
The most recent National Water Quality Inventory reports that runoff
from urban areas is the leading source of impairments to surveyed
estuaries and the third largest source of water quality impairments to
surveyed lakes. In addition, population and development trends indicate
that by 2010 more than half of the Nation will live in coastal towns and
cities. Runoff from these rapidly growing urban areas will continue to
degrade coastal waters.
To protect surface water and ground water quality, urban development
and household activities must be guided by plans that limit runoff and
reduce pollutant loadings. To this end, communities can address urban
water quality problems on both a local and watershed level and garner
the institutional support to help address urban runoff problems.
How Urban Areas Affect Runoff
Increased Runoff. The porous and varied terrain of natural landscapes
like forests, wetlands, and grasslands trap rainwater and snowmelt and
allow it to slowly filter into the ground. Runoff tends to reach receiving
waters gradually. In contrast, nonporous urban landscapes like roads,
bridges, parking lots, and buildings don't let runoff slowly percolate into
the ground. Water remains above the surface, accumulates, and runs off
in large amounts.
Cities install storm sewer systems that quickly channel this runoff from
roads and other impervious surfaces. Runoff gathers speed once it enters
the storm sewer system. When it leaves the system and empties into a
stream, large volumes of quickly flowing runoff erode streambanks,
damage streamside vegetation, and widen stream channels. In turn, this
will result in lower water depths during non-storm periods, higher than
normal water levels during wet weather periods, increased sediment
loads, and higher water temperatures. Native fish and other aquatic life
cannot survive in urban streams severely impacted by urban runoff.
Increased Pollutant Loads. Urbanization also increases the variety and amount of pollutants
transported to receiving waters. Sediment from development and new construction; oil, grease, and
toxic chemicals from automobiles; nutrients and pesticides from turf management and gardening;
viruses and bacteria from failing septic systems; road salts; and heavy metals are examples of pollutants
generated in urban areas. Sediments and solids constitute the largest volume of pollutant loads to
receiving waters in urban areas.
When runoff enters storm drains, it carries many of these pollutants with it. In older cities, this polluted
runoff is often released directly into the water without any treatment. Increased pollutant loads can
harm fish and wildlife populations, kill native vegetation, foul drinking water supplies, and make

recreational areas unsafe.
Point and Nonpoint Distinctions
There are two different types of laws that help control urban runoff: one focusing on urban point
sources and the other focusing on urban nonpoint sources. Urban point source pollution is addressed
by the National Pollution Discharge Elimination System permit program of the Clean Water Act, which
regulates stormwater discharges. Urban nonpoint source pollution is covered by nonpoint source
management programs developed by states, territories, and tribes under the Clean Water Act. In states
and territories with coastal zones, programs to protect coastal waters from nonpoint source pollution
also are required by section 6217 of the Coastal Zone Act Reauthorization Amendments.
Measures to Manage Urban Runoff
Plans for New Development. New developments should attempt to maintain the volume of runoff at
predevelopment levels by using structural controls and pollution prevention strategies. Plans for the
management of runoff, sediment, toxics, and nutrients can establish guidelines to help achieve both
goals. Management plans are designed to protect sensitive ecological areas, minimize land
disturbances, and retain natural drainage and vegetation.
Plans for Existing Development. Controlling runoff from existing urban areas tends to be relatively
expensive compared to managing runoff from new developments. However, existing urban areas can
target their urban runoff control projects to make them more economical. Runoff management plans
for existing areas can first identify priority pollutant reduction opportunities, then protect natural areas
that help control runoff, and finally begin ecological restoration and retrofit activities to clean up
degraded water bodies. Citizens can help prioritize the clean-up strategies, volunteer to become
involved with restoration efforts, and help protect ecologically valuable areas.
Plans for Onsite Disposal Systems. The control of nutrient and pathogen loadings to surface waters
can begin with the proper design, installation, and operation of onsite disposal systems (OSDSs). These
septic systems should be situated away from open waters and sensitive resources such as wetlands and
floodplains. They should also be inspected, pumped out, and repaired at regular time intervals.
Household maintenance of septic systems can play a large role in preventing excessive system
discharges.
Public Education. Schools can conduct education projects that teach students how to prevent
pollution and keep water clean. In addition, educational outreach can target specific enterprises, such
as service stations, that have opportunities to control runoff onsite. Many communities have
implemented storm drain stenciling programs that discourage people from dumping trash directly into
storm sewer systems.

STORMWATER BEST MANAGEMENT PRACTICES
The following are a list of BMPs may be used to minimize the introduction of pollutants
of concern that may result in significant impacts to receiving waters. Other BMPs
approved by the Copermittee as being equally or more effective in pollutant reduction
than comparable BMPs identified below are acceptable. See Appendix B: Suggested
Resources for additional sources of information. All BMPs must comply with local
zoning and building codes and other applicable regulations.
Site Design BMPs
Minimizing Impervious Areas
• Reduce sidewalk widths
• Incorporate landscaped buffer areas between sidewalks and streets.
• Design residential streets for the minimum required pavement widths
• Minimize the number of residential street cul-de-sacs and incorporate
landscaped areas to reduce their impervious cover.
• Use open space development that incorporates smaller lot sizes
• Increase building density while decreasing the building footprint
• Reduce overall lot imperviousness by promoting alternative driveway
surfaces and shared driveways that connect two or more homes together
• Reduce overall imperviousness associated with parking lots by providing
compact car spaces, minimizing stall dimensions, incorporating efficient
parking lanes, and using pervious materials in spillover parking areas
Increase Rainfall Infiltration
• Use permeable materials for private sidewalks, driveways, parking lots, and
interior roadway surfaces (examples: hybrid lots, parking groves, permeable
overflow parking, etc.)
• Direct rooftop runoff to pervious areas such as yards, open channels, or
vegetated areas, and avoid routing rooftop runoff to the roadway or the urban
runoff conveyance system
Maximize Rainfall Interception
• Maximizing canopy interception and water conservation by preserving
existing native trees and shrubs, and planting additional native or drought
tolerant trees and large shrubs.

Cleanup and Storage Procedures
m Minor Spills
- Minor spills typically involve small quantities of oil, gasoline, paint, etc.,
which can be controlled by the first responder at the discovery of the
spilL
- Use absorbent materials on small spills rather than hosing down or
burying the spill.
- Remover the absorbent materials promptly and dispose of properly.
- The practice commonly followed for a minor spill is:
- Contain the spread of the spill.
- Recover spilled materials.
- Clean the contaminated area and/or properly dispose of contaminated
materials.
• Semi-Significant Spills
- Semi-significant spills sail can be controlled by the first responder along
with the aid of other personnel such as laborers and the foreman, etc.
This response may require the cessation of all other activities.
- Clean up spills immediately:
- Notify the project foreman immediately. The foreman shall notify the
Resident Engineer (RE).
- Contain spread of the spill.
- If the spill occurs on paved or impermeable surfaces, clean up using
"dry" methods (absorbent materials, cat litter and/or rags). Contain
the spill by encircling with absorbent materials and do not let the spill
spread widely.
- If the spill occurs in dirt areas, immediately contain the spill by
constructing an earthen dike. Dig up and properly dispose of
contaminated soil.
- If the spill occurs during rain, cover spill with tarps or other material
to prevent contaminating runoff.

• Significant/Hazardous Spills
- For significant of hazardous spills that cannot be controlled by personnel
in the immediate vicinity, the following steps shall be taken:
- Notify the RE immediately and follow up with a written report
- Notify the local emergency response by dialing 911. In addition to
911, the contractor will notify the proper county officials. It is the
contractor's responsibility lo have all emergency phone numbers at
the construction site.
- Notify the Governor's Office of Emergency Services Warning Center,
(805) 852-7550.
- For spills of federal reportable quantities, in confonnance with the
requirements in 40 CFR parts 110,119, and 302, the contractor shall
notify the National Response Center at (800) 424-8802.
- Notification shall first be made by telephone and followed up with a
written report
- The services of a spills contractor or a Haz-Mat team shall be
obtained immediately. Construction personnel shall not attempt to
clean up the spill until the appropriate and qualified staffhave arrived
at the job site.
- Other agencies which may need to be consulted include, but are not
limited to, the Fire Department, the Public Works Department, the
Coast Guard, the Highway Patrol, the City/County Police
Department, Department of Toxic Substances, California Division of
Oil and Gas, CaVOSHA, RWQCB, etc.
Maintenance and • Verify weekly that spill control clean up materials are located near material
Inspection storage, unloading, and use areas.
• Update spill prevention and control plans and stock appropriate clean-up
materials whenever changes occur in the types of chemicals used or stored
onsite.

Solid Waste Management
• Construction material visible to the public shall be stored or stacked in an
orderly manner to the satisfaction of the RE.
• Storm water run-on shall be prevented from contacting stored solid waste
through the use of berms, dikes, or other temporary diversion structures or
through the use of measures to elevate waste from site surfaces.
• Solid waste storage areas shall be located at least 15 m (50 ft) from drainage
facilities and watercourses and shall not be located in areas prone to flooding
or ponding.
• Except during fair weather, construction and highway planting waste not
stored in watertight dumpsters shall be securely covered from wind and rain
by covering the waste with tarps or plastic sheeting or protected in
conformance with the applicable Disturbed Sofl Area protection section.
• Dumpster washout on the project site is not allowed.
• Notify trash hauling contractors that only watertight dumpsters are acceptable
for use on-site.
• Plan for additional containers during the demolition phase of construction.
• Plan for more frequent pickup during the demolition phase of construction.
• Construction waste shall be stored in a designated area approved by the RE.
• Segregate potentially hazardous waste from non-hazardous construction site
waste.
• Keep the site clean of litter debris.
• Make sure that toxic liquid wastes (e.g., used oils, solvents, and paints) and
chemicals (e.g., acids, pesticides, additives, curing compounds) are not
disposed Of in dumpsters designated for construction debris.
• ' Dispose of non-hazardous waste in accordance with Standard Specification
7-1,13, Disposal of Material Outside the Highway Right of Way.
• For disposal of hazardous waste, see BMP WM-6, "Hazardous Waste
Management" Have hazardous waste hauled to an appropriate disposal
and/or recycling facility.
• Salvage or recycle useful vegetation debris, packaging and/or surplus building
materials when practical. For example, trees and shrubs from land clearing
can be converted into wood chips, then used as mulch on graded areas. Wood
pallets, cardboard boxes, and construction scraps can also be recycled.
