7.4.1 Sampling and Analysis Plan for Non-Visible Pollutants in Stormwater
Runoff Discharges
This Sampling and Analysis Plan for Non-Visible Pollutants describes the sampling and analysis
strategy and schedule for monitoring non-visible pollutants in stormwater runoff discharges from
the project site.
Sampling for non-visible pollutants will be conducted when (1) a breach, leakage, malfunction,
or spill is observed; and (2) the leak or spill has not been cleaned up prior to the rain event; and
(3) there is the potential for discharge of non-visible pollutants to surface waters or drainage
system.
The following construction materials, wastes, or activities, are potential sources of non-visible
pollutants to stormwater discharges from the project. Storage, use, and operational locations are
shown on the Site Maps in Appendix B.
• Spilled Materials
• Waste
7.4.2 Sampling and Analysis Plan for Turbidity in Stormwater Runoff Discharges
The project consists of the removal and construction of a single family residence located near the
ocean. Due to the nature of the sandy soil, not much turbidity is expected in the runoff. Most of
the runoff should percolate back into the ground. The contractor shall follow the same
procedures for Non-Visible Pollutants sampling.

2 A) R Factor
Analyses of data indicated that when factors other than rainfall are held constant, soil loss is directly proportional to a
rainfall factor composed of total storm kinetic energy (E) times the maximum 30-min intensity (130) (Wischmeier and
Smith, 1958). The numerical value of R is the average annual sum of El30 for storm events during a rainfall record of
at least 22 years. "lsoerodent" maps were developed based on R values calculated for more than 1000 locations in
3 the Western U.S. Refer to the link below to determine the R factor for the project site.

5 R Factor Value 30
6 B) K Factor Cweiahted averaae, by area, for all site soils)
The soil-erodibility factor K represents: (1) susceptibility of soil or surface material to erosion, (2) transportability of the
sediment, and (3) the amount and rate of runoff given a particular rainfall input, as measured under a standard
condition. Fine-textured soils that are high in clay have low K values (about 0.05 to 0.15) because the particles are
resistant to detachment. Coarse-textured soils, such as sandy soils, also have low K values (about 0.05 to 0.2)
because of high infiltration resulting in low runoff even though these particles are easily detached. Medium-textured
soils, such as a silt loam, have moderate K values (about 0.25 to 0.45) because they are moderately susceptible to
particle detachment and they produce runoff at moderate rates. Soils having a high silt content are especlally
susceptible to erosion and have high K values, which can exceed 0.45 and can be as large as 0.65. Silt-size particles
are easily detached and tend to crust, producing high rates and large volumes of runoff. Use Site-specific data must
7 be submitted.
8 Site-sgecific K factor guidance
9 K Factor Value 0.1
10 C) LS Factor (weiahted average, by area, for all slopes)
The effect of topography on erosion is accounted for by the LS factor, which combines the effects of a hillslope-length
factor, L, and a,hillslope-gradient factor, £. Generally speaking, as taillslope length and/or hillslope gradient increase,
soil loss increases. As hillslope length increases, total soil loss and soil loss per unit area increase due to the
progressive accumulation of runoff in the downslope direction. As the hillslope gradient increases, the velocity and
erosivity of runoff increases. Use the LS table located in separate tab of this spreadsheet to determine LS factors.

Scheduling
Description and Purpose
Scheduling is the development of a ~itten plan that includes
sequencing of construction activities and the implementation of
BMPs such as erosion control and sediment control while
taking local climate (rainfall, wind, etc.) into consideration.
The purpose is to reduce the amount and duration of soil
exposed to erosion by wind, rain, runoff, and vehicle tracking,
and to perform the construction activities and control practices
in accordance with the planned schedule.
Suitable Applications
Proper sequencing of construction activities to reduce erosion
potential should be incorporated into the schedule of every
construction project especially during rainy season. Use of
other, more costly yet less effective, erosion and sediment
control BMPs may often be reduced through proper
construction sequencing.
Limitations
• Environmental constraints such as nesting season
prohibitions reduce the full capabilities of this BMP.
Implementation
• Avoid rainy periods. Schedule major grading operations
during dry months when practical. Allow enough time
before rainfall begins to stabilize the soil with vegetation or
physical means or to install sediment trapping devices.
• Plan the project and develop a schedule showing each phase
of construction. Clearly show how the rainy season relates

to soil disturbing and re-stabilization activities. Incorporate the construction schedule into
theSWPPP.
• Include on the schedule, details on the rainy season implementation and deployment of:
Erosion control BMPs
Sediment control BMPs
Tracking control BMPs
Wind erosion control BMPs
Non-stormwater BMPs
Waste management and materials pollution control BMPs
• Include dates for activities that may require non-stormwater discharges such as dewatering,
sawcutting, grinding, drilling, boring, crushing, blasting, painting, hydro-demolition, mortar
mixing, pavement cleaning, etc.
" Work out the sequencing and timetable for the start and completion of each item such as site
clearing and grubbing, grading; excavation, paving, foundation pouring utilities installation,
etc., to minimize the active construction area during the rainy season.
Sequence trenching activities so that most open portions are closed before new
trenching begins.
Incorporate staged seeding and re-vegetation of graded slopes as work progresses.
Schedule establishment of permanent vegetation during appropriate planting time for
specified vegetation.
• Non-active areas should be stabilized as soon as practical after the cessation of soil
disturbing activities or one day prior to the onset of precipitation.
• Monitor the weather forecast for rainfall.
• When rainfall is predicted, adjust the construction schedule to allow the implementation of
soil stabilization and sediment treatment controls on all disturbed areas prior to the onset of
rain.
• Be prepared year round to deploy erosion control and sediment control BMPs. Erosion may
be caused during dry seasons by un-seasonal rainfall, wind, and vehicle tracking. Keep the
site stabilized year round, and retain and maintain rainy season sediment trapping devices
in operational condition.
• Apply permanent erosion control to areas deemed substantially complete during the
project's defined seeding window.
Costs
Construction scheduling to reduce erosion may increase other construction costs due to reduced
economies of scale in performing site grading. The cost effectiveness of scheduling techniques
should be compared with the other less effective erosion and sedimentation controls to achieve a
cost effective balance.

Gravel Bag Berm
Description and Purpose
A gravel bag berm is a series of gravel-filled bags placed on a
level contour to intercept sheet flows. Gravel bags pond sheet
flow runoff, allowing sediment to settle out, and release runoff
slowly as sheet flow, preventing erosion.
Suitable Applications
Gravel bag berms may be suitable:
• AB a linear sediment control measure:
Below the toe of slopes and erodible slopes
AB sediment traps at culvert/pipe outlets
Below other small cleared areas
Along the perimeter of a site
Down slope of exposed soil areas
Around temporary stockpiles and spoil areas
Parallel to a roadway to keep sediment off paved areas
Along streams and channels
• As a linear erosion control measure:
Along the face and at grade breaks of exposed and
erodible slopes to shorten slope length and spread
runoff as sheet flow.

At the top of slopes to divert runoff away from disturbed slopes.
As chevrons (small check dams) across mildly sloped construction roads. For use check
dam use in channels, see SE-4, Check Dams.
Limitations
• Gravel berms may be difficult to remove.
• Removal problems limit their usefulness in landscaped areas.
• Gravel bag berm may not be appropriate for drainage areas greater than 5 acres.
• Runoff will pond upstream of the berm, possibly causing flooding if sufficient space does not
exist.
• Degraded gravel bags may rupture when removed, spilling contents.
• Installation can be labor intensive.
• Durability of gravel bags is somewhat limited and bags may need to be replaced when
installation is required for longer than 6 months. ·
• Easily damaged by construction equipment.
• When used to detain concentrated flows, maintenance requirements increase.
Implementation
General
A gravel bag berm consists of a row of open graded gravel-filled bags placed on a level contour.
When appropriately placed, a gravel bag berm intercepts and slows sheet flow runoff, causing
temporary ponding. The temporary ponding allows sediment to settle. The open graded gravel
in the bags is porous, which allows the ponded runoff to flow slowly through the bags, releasing
the runoff as sheet flows. Gravel bag berms also interrupt the slope length and thereby reduce
erosion by reducing the tendency of sheet flows to concentrate into rivulets, which erode rills,
and ultimately gullies, into disturbed, sloped soils. Gravel bag berms are similar to sand bag
barriers, but are more porous. Generally, gravel bag berms should be used in conjunction with
temporary soil stabilization controls up slope to provide effective erosion and sediment control.
Design and Layout
• Locate gravel bag berms on level contours.
• When used for slope interruption, the following slope/sheet flow length combinations apply:
Slope inclination of 4:1 (H:V) or flatter: Gravel bags should be placed at a maximum
interval of 20 ft, with the first row near the slope toe.
Slope inclination between 4:1 and 2:1 (H:V): Gravel bags should be placed at a maximum
interval of 15 ft. (a closer spacing is more effective), with the first row near the slope toe.

Grallel Bag .13erm SE-6
Slope inclination 2:1 (H:V) or greater: Gravel bags should be placed at a maximum
interval of 10 ft. (a closer spacing is more effective), with the first row near the slope toe.
• Turn the ends of the gravel bag barriers up slope to prevent runoff from going around the
berm.
• Allow sufficient space up slope from the gravel bag berm to allow ponding, and to provide
room for sediment storage.
• For installation near the toe of the slope, gravel bag barriers should be set back from the
slope toe to facilitate cleaning. Where specific site conditions do not allow for a set-back,the
gravel bag barrier may be constructed on the toe of the slope. To prevent flows behind the
barrier, bags can be placed perpendicular to a berm to serve as cross barriers.
• Drainage area should not exceed 5 acres.
• In Non-Traffic Areas:
Height ::::: 18 in. maximum
Top width = 24 in. minimum for three or more layer construction
Top width ::::: 12 in. minimum for one or two layer construction
Side slopes::::: 2:1 (H:V) or flatter
• In Construction Traffic Areas:
Height = 12 in. maximum
Top width ::::: 24 in. minimum for three or more layer construction.
Top width = 12 in. minimum for one or two layer construction.
Side slopes= 2:1 (H:V) or flatter.
• Butt ends of bags tightly.
• On multiple row, or multiple layer construction, overlap butt joints of adjacent row and row
beneath.
• Use a pyramid approach when stacking bags.
Materials
• Bag Material: Bags should be woven polypropylene, polyethylene or polyamide fabric or
burlap, minimum unit weight of 4 ounces/yd2, Mullen burst strength exceeding 300 lb/in2 in
conformance with the requirements in ASTM designation D3786, and ultraviolet stability
exceeding 70% in conformance with the requirements in ASTM designation D4355.

Gravel Bag Berm SE-6
• Bag Size: Each gravel-filled bag should have a length of 18 in., width of 12 in., thickness of
3 in., and mass of approximately 33 lbs. Bag dimensions are nominal, and may vary based
on locally available materials.
• Fill Material: Fill material should be 0.5 to 1 in. crushed rock, clean and free from clay,
organic matter, and other deleterious material, or other suitable open graded, non-cohesive,
porous gravel.
Costs
Material costs for gravel bags are average and are dependent upon material availability. $2.50-
3.00 per filled gravel bag is standard based upon vendor research.
Inspection and Maintenance
• BMPs must be inspected in accordance with General Permit requirements for the associated
project type and risk level. It is recommended that at a minimum, BMPs be inspected
weekly, prior to forecasted rain events, daily during extended rain events, and after the
conclusion of rain events.
• Gravel bags exposed to sunlight will need to be replaced every two to three months due to
degrading of the bags.
• Reshape or replace gravel bags as needed.
• Repair washouts or other damage as needed.
• Sediment that accumulates in the BMP should be periodically removed in order to maintain
BMP effectiveness. Sediment should be removed when the sediment accumulation reaches
one-third of the barrier height.
• Remove gravel bag berms when no longer needed and recycle gravel fill whenever possible
and properly dispose of bag material. Remove sediment accumulation and clean, re-grade,
and stabilize the area.

Stabilized Construction Entrance/Exit TC-1
Description and Purpose
·~ ~ ......
A stabilized construction access is defined by a point of
entrance/ exit to a construction site that is stabilized to reduce
the tracking of mud and dirt onto public roads by construction
vehicles.
Suitable Applications
Use at construction sites:
• Where dirt or mud can be tracked onto public roads.
• Adjacent to water bodies.
• Where poor soils are encountered.
• Where dust is a problem during dry weather conditions.
Limitations
• Entrances and exits require periodic top dressing with
additional stones.
• This BMP should be used in conjunction with street
sweeping on adjacent public right of way.
• Entrances and exits should be constructed on level ground
only.
• Stabilized construction entrances are rather expensive to
construct and when a wash rack is included, a sediment trap
of some kind must also be provided to collect wash water
runoff.

Stabilized Construction Entrance/Exit TC-1
Implementation
General
A stabilized construction entrance is a pad of aggregate underlain with filter cloth located at any
point where traffic will be entering or leaving a construction site to or from a public right of way,
street, alley, sidewalk, or parking area. The purpose of a stabilized construction entrance is to
reduce or eliminate the tracking of sediment onto public rights of way or streets. Reducing
tracking of sediments and other pollutants onto paved roads helps prevent deposition of
sediments into local storm drains and production of airborne dust.
Where traffic will be entering or leaving the construction site, a stabilized construction entrance
should be used. NPDES permits require that appropriate measures be implemented to prevent
tracking of sediments onto paved roadways, where a significant source of sediments is derived
from mud and dirt carried out from unpaved roads and construction sites.
Stabilized construction entrances are moderately effective in removing sediment from
equipment leaving a construction site. The entrance should be built on level ground.
Advantages of the Stabilized Construction Entrance/Exit is that it does remove some sediment
from equipment and serves to channel construction traffic in and out of the site at specified
locations. Efficiency is greatly increased when a washing rack is included as part of a stabilized
construction entrance/exit.
Design and Layout
• Construct on level ground where possible.
• Select 3 to 6 in. diameter stones.
• Use minimum depth of stones of 12 in. or as recommended by soils engineer.
• Construct length of 50 ft or maximum site will allow, and 10 ft minimum width or to
accommodate traffic.
• Rumble racks constructed of steel panels with ridges and installed in the stabilized
entrance/exit will help remove additional sediment and to keep adjacent streets clean.
• Provide ample turning radii as part of the entrance.
• Limit the points of entrance/exit to the construction site.
• Limit speed of vehicles to control dust.
• Properly grade each construction entrance/exit to prevent runoff from leaving the
construction site.
• Route runoff from stabilized entrances/ exits through a sediment trapping device before
discharge.
• Design stabilized entrance/exit to support heaviest vehicles and equipment that will use it.

• Select construction access stabilization (aggregate, asphaltic concrete, concrete) based on
longevity, required performance, and site conditions. Do not use asphalt concrete (AC)
grindings for stabilized construction access/roadway.
• If aggregate is selected, place crushed aggregate over geotextile fabric to at least 12 in. depth,
or place aggregate to a depth recommended by a geotechnical engineer. A crushed aggregate
greater than 3 in. but smaller than 6 in. should be used.
• Designate combination or single purpose entrances and exits to the construction site.
• Require that all employees, subcontractors, and suppliers utilize the stabilized construction
access.
• Implement SE-7, Street Sweeping and Vacuuming, as needed.
• All exit locations intended to be used for more than a two-week period should have stabilized
construction entrance/exit BMPs.
Inspection and Maintenance
• Inspect and verify that activity~based BMPs are in place prior to the commencement of
associated activities. While activities associated with the BMPs are under way, inspect BMPs
in accordance with General Permit requirements for the associated project type and risk
level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted
rain events, daily during extended rain events, and after the conclusion of rain events.
• Inspect local roads adjacent to the site daily. Sweep or vacuum to remove visible
accumulated sediment.
• Remove aggregate, separate and dispose of sediment if construction entrance/exit is clogged
with sediment.
• Keep all temporary roadway ditches clear.
• Check for damage and repair as needed.
• Replace gravel material when surface voids are visible.
• Remove all sediment deposited on paved roadways within 24 hours.
• Remove gravel and filter fabric at completion of construction
Costs
Average annual cost for installation and maintenance may vary from $1,200 to $4,800 each,
averaging $2,400 per entrance. Costs will increase with addition of washing rack, and sediment
trap. With wash rack, costs range from $1,200 -$6,000 each, averaging $3,600 per entrance.

Wind Erosion Control
Description and Purpose
Wind erosion or dust control consists of applying water or other
chemical dust suppressants as necessary to prevent or alleviate
dust nuisance generated by construction activities. Covering
small stockpiles or areas is an alternative to applying water or
other dust palliatives.
California's Mediterranean climate, with a short "wet" season
and a typically long, hot "dry" season, allows the soils to
thoroughly dry out. During the dry season, construction
activities are at their peak, and disturbed and exposed areas are
increasingly subject to wind erosion, sediment tracking and
dust generated by construction equipment. Site conditions and
climate can make dust control more of an erosion problem than
water based erosion. Additionally, many local agencies,
including Air Quality Management Districts, require dust
control and/or dust control permits in order to comply with
local nuisance laws, opacity laws (visibility impairment) and the
requirements of the Clean Air Act. Wind erosion conh·ol is
required to be implemented at all construction sites greater
than 1 acre by the General Permit.
Suitable Applications
Most BMPs that provide protection against water-based erosion
will also protect against wind-based erosion and dust control
requirements required by other agencies will generally meet
wind erosion control requirements for water quality protection.
Wind erosion control BMPs are suitable during the following
construction activities:

• · Construction vehicle traffic on unpaved roads
• Drilling and blasting activities
• Soils and debris storage piles
• Batch drop from front-end loaders
• Areas with unstabilized soil
• Final grading/ site stabilization
Limitations ·
• Watering prevents dust only for a short period (generally less than a few hours) and should
be applied daily ( or more often) to be effective.
• Over watering may cause erosion and track-out.
• Oil or oil-treated subgrade should not be used for dust control because the oil may migrate
into drainageways and/ or seep into the soil.
• Chemical dust suppression agents may have potential environmental impacts. Selected
chemical dust control agents should be environmentally benign.
• Effectiveness of controls depends on soil, temperature, humidity, wind velocity and traffic.
• Chemical dust suppression agents should not he used within 100 feet of wetlands or water
bodies.
• Chemically treated subgrades may make the soilwater repellant, interfering with long-term
infiltration and the vegetation/re-vegetation of the site. Some chemical dust suppressants
may be subject to freezing and may contain solvents and should be handled properly.
• In compacted areas, watering and other liquid dust control measures may wash sediment or
other constituents into the drainage system.
• If the soil surface has minimal natural moisture, the affected area may need to be pre-wetted
so that chemical dust control agents can uniformly penetrate the soil surface.
Implementation
Dust Control Practices
Dust control BMPs generally stabilize exposed surfaces and minimize activities that suspend or
track dust particles. The following table presents dust control practices that can be applied to
varying site conditions that could potentially cause dust. For heavily traveled and disturbed
areas, wet suppression (watering), chemical dust suppression, gravel asphalt surfacing,
temporary gravel construction entrances, equipment wash-:out areas, and haul truck covers can
be employed as dust control applications. Permanent Ortemporary vegetation and mulching
can be employed for areas of occasional or no construction traffic. Preventive measures include
minimizing surface areas to be disturbed, limiting onsite vehicle traffic to 15 mph or less, and
controlling the number and activity of vehicles on a site at any given time.

Chemical dust suppressants include: mulch and fiber based dust palliatives (e.g. paper mulch
with gypsum binder), salts and brines (e.g. calcium chloride, magnesium chloride), non-
petroleum based organics (e.g. vegetable oil, lignosulfonate), petroleum based organics (e.g.
asphalt emulsion, dust oils, petroleum resins), synthetic polymers (e.g. polyvinyl acetate, vinyls,
acrylic), clay additives (e.g. bentonite, montimorillonite) and electrochemical products (e.g.
enzymes, ionic products).

Additional preventive measures include:
• Schedule construction activities to minimize exposed area (see EC-1, Scheduling).
• Quickly treat exposed soils using water, mulching, chemical dust suppressants, or
stone/ gravel layering.
• Identify and stabilize key access points prior to commencement of construction.
• Minimize the impact of dust by anticipating the direction of prevailing winds.
• Restrict construction traffic to stabilized roadways within the project site, as practicable.
• Water should be applied by means of pressure-type distributors or pipelines equipped with a
spray system or hoses and nozzles that will ensure even distribution.
• All distribution equipment should be equipped with a positive means of shutoff.
• Unless water is applied by means of pipelines, at least one mobile unit should be available at
all times to apply water or dust palliative to the project.
• If reclaimed waste water is used, the sources and discharge must meet California
Department of Health Services water reclamation criteria and the Regional Water Quality

Control Board (RWQCB) requirements. Non-potable water should not be conveyed in tanks
or drain pipes that will be used to convey potable water and there should be no connection
between potable and non-potable supplies. Non-potable tanks, pipes, and other
conveyances should be marked, "NON-POTABLE WATER-DO NOT DRINK."
• Pave or chemically stabilize access points where unpaved traffic surfaces adjoin paved roads.
• Provide covers for haul trucks transporting materials that contribute to dust.
• Provide for rapid clean up of sediments deposited on paved roads. Furnish stabilized
construction road entrances and wheel wash areas.
• Stabilize inactive areas of construction sites using temporary vegetation or chemical
stabilization methods.
For chemical stabilization, there are many products available for chemically stabilizing gravel
roadways and stockpiles. If chemical stabilization is used, the chemicals should not create any
adverse effects on stormwater, plant life, or groundwater and should meet all applicable
regulatory requirements.
Costs
Installation costs for water and chemical dust suppression vary based on the method used and
the length of effectiveness. Annual costs may be high since some of these measures are effective
for only a few hours to a few days.
Inspection and Maintenance
• Inspect and verify that activity-based BMPs are in place prior to the commencement of
associated activities.
• BMPs must be inspected in accordance with General Permit requirements for the associated
project type and risk level. It is recommended that at a minimum, BMPs be inspected
weekly, prior to forecasted rain events, daily during extended rain events, and after the
conclusion of rain events.
• Check areas protected to ensure coverage.
• Most water-based dust control measures require frequent application, often daily or even
multiple times per day. Obtain vendor or independent information on longevity of chemical
dust suppressants.

Water Conservation Practices NS-1
Description and Purpose
Water conservation practices are activities that use water
during the construction of a project in a manner that avoids
causing erosion and the transport of pollutants offsite. These
practices can reduce or eliminate non-stormwater discharges.
Suitable Applications
Water conservation practices are suitable for all construction
sites where water is used, including piped water, metered
water, trucked water, and water from a reservoir.
Limitations
• None identified.
Implementation
• Keep water equipment in good working condition.
• Stabilize water truck filling area.
• Repair water leaks promptly.
• Washing of vehicles and equipment on the construction site
is discouraged.
• Avoid using water to clean construction areas. If water
must be used for cleaning or surface preparation, surface
should be swept and vacuumed first to remove dirt. This
will minimize amount of water required.

Paving and Grinding Operations NS-3
""
Description and Purpose
Prevent or reduce the discharge of pollutants from paving
operations, using measures to prevent runon and runoff
pollution, properly disposing of wastes, and training employees
and subcontractors.
The General Permit incorporates Numeric Action Levels (NAL)
for pH and turbidity (see Section 2 of this handbook to
determine your project's risk level and if you are subject to
these requirements).
Many types of construction materials associated with paving
and grinding operations, including morta.r, concrete, and
cement and their associated wastes have basic chemical
properties that can raise pH levels outside of the permitted
range. Additional care should be taken when managing these
materials to prevent them from coming into contact with
stormwater flows, which could lead to exceedances of the
General Permit requirements.
Suitable Applications
These procedures are implemented where paving, surfacing,
resurfacing, or sawcutting, may pollute stormwater runoff or
discharge to the storm drain system or watercourses.
Limitations
• Paving opportunities may be limited during wet weather.
Discharges of freshly paved surfaces may raise pH to
environmentally harmful levels and trigger permit
violations.

Paving and Grinding Operations
Implementation
General
• Avoid paving during the wet season when feasible.
11 Reschedule paving and grinding activities if rain is forecasted.
• Train employees and sub-contractors in pollution prevention and reduction.
NS-3
• Store materials away from drainage courses to prevent stormwater runon (see WM-1,
Material Delivery and Storage).
11 Protect drainage courses, particularly in areas with a grade, by employing BMPs to divert
runoff or to trap and filter sediment.
• Stockpile material removed from roadways away from drain inlets, drainage ditches, and
watercourses. These materials should be stored consistent with WM-3, Stockpile
Management.
m Disposal of PCC (Portland cement concrete) and AC (asphalt concrete) waste should be in
conformance with WM-8, Concrete Waste Management.
Saw Cutting, Grinding, and Pavement Removal
• Shovel or vacuum saw-cut slurry and remove from site~ Cover or barricade storm drains
during saw cutting to contain slurry.
• When paving involves AC, the following steps should be implemented to prevent the
discharge of grinding residue, uncompacted or loose AC, tack coats, equipment cleaners, or
unrelated paving materials:
AC grindings, pieces, or chunks used in embankments or shoulder backing should not be
allowed to enter any storm drains or watercourses. Install inlet protection and perimeter
cuntrols until area is stabilized (i.e. cutting, grinding or other removal activities are
complete and loose material has been properly removed and disposed oDor permanent
controls are in place. Examples of temporary perimeter controls can be found in EC-9,
Earth Dikes and Drainage Swales; SE-1, Silt Fence; SE-5, Fiber Rolls, or SE-13 Compost
Socks and Berms
Collect and remove all broken asphalt and recycle when practical. Old or spilled asphalt
should be recycled or disposed of properly.
• Do not allow saw-cut slurry to enter storm drains or watercourses. Residue from grinding
operations should be picked up by a vacuum attachment to the grinding machine, or by
sweeping, should not be allowed to flow across the pavement, and should not be left on the
surface of the pavement. See also WM-8, Concrete Waste Management, and WM-10, Liquid
Waste Management.
• Pavement removal activities should not be conducted in the rain.
• Collect removed pavement material by mechanical or manual methods. This material may
be recycled for use as shoulder backing or base material.

11 If removed pavement material cannot be recycled, transport the material back to an
approved storage site.
Asphaltic Concrete Paving
• If paving involves asphaltic cement concrete, follow these steps:
Do not allow sand or gravel placed over new asphalt to wash into storm drains, streets,
or creeks. Vacuum or sweep loose sand and gravel and properly dispose of this waste by
referring to WM-5, Solid Waste Management.
Old asphalt should be disposed of properly. Collect and remove all broken asphalt from
the site and recycle whenever possible.
Portland Cement Concrete Paving
• Do not wash sweepings from exposed aggregate concrete into a storm drain system. Collect
waste materials by dry methods, such as sweeping or shoveling, and return to aggregate base
stockpile or dispose of properly. Allow aggregate rinse to settle. Then, either allow rinse
water to dry in a temporary pit as described in WM-8, Concrete Waste Management, or
pump the water to the sanitary sewer if authorized by the local wastewater authority.
Sealing Operations
• During chip seal application and sweeping operations, petroleum or petroleum covered
aggregate should not be allowed to enter any storm drain or water courses. Apply temporary
perimeter controls until structure is stabilized (i.e. all sealing operations are complete and
cured and loose materials have been properly removed and disposed).
• Inlet protection (SE-10, Storm Drain Inlet Protection) should be used during application of
seal coat, tack coat, slurry seal, and fog seal.
• Seal coat, tack coat, slurry seal, or fog seal should not be applied if rainfall is predicted to
occur during the application or curing period.
Paving Equipment
• Leaks and spills from paving equipment can contain toxic levels of heavy metals and oil and
grease. Place drip pans or absorbent materials under paving equipment when not in use.
Clean up spills with absorbent materials and dispose of in accordance with the applicable
regulations. See NS-10, Vehicle and Equipment Maintenance, WM-4, Spill Prevention and
Control, and WM-10, Liquid Waste Management.
• Substances used to coat asphalt transport trucks and asphalt spreading equipment should
not contain soap and should be non-foaming and non-toxic.
• Paving equipment parked onsite should be parked over plastic to prevent soil
contamination.
• Clean asphalt coated equipment offsite whenever possible. When cleaning dry, hardened
asphalt from equipment, manage hardened asphalt debris as described in WM-5, Solid
Waste Management. Any cleaning onsite should follow NS-8, Vehicle and Equipment
Cleaning.

Thermoplastic Striping
11 Thermoplastic striper and pre-heater equipment shutoff valves should be inspected to
ensure that they are working properly to prevent leaking thermoplastic from entering drain
inlets, the storrnwater drainage system, or watercourses.
• Pre-heaters should be filled carefully to prevent splashing or spilling of hot thermoplastic.
Leave six inches of space at the top of the pre-heater container when filling thermoplastic to
allow room for material to move.
• Do not pre-heat, transfer, or load thermoplastic near drain inlets or watercourses.
• Clean truck beds daily ofloose debris and melted thermoplastic. When possible, recycle
thermoplastic material.
Raised/Recessed Pavement Marker Application and Removal
• Do not transfer or load bituminous material near drain inlets, the stormwater drainage
system, or watercourses.
• Melting tanks should be loaded with cate and not filled to beyond six inches from the top to
leave room for splashing.
• When servicing or filling melting tanks, ensure all pressure is released before removing lids
to avoid spills.
• On large-scale projects, use mechanical or manual methods to collect excess bituminous
material from the roadway after removal of markers.
Costs
• All of the above are low cost measures.
Inspection and Maintenance
• Inspect and vsrify that activity-based I3MPs are in place prior to the commencement of
paving and grinding operations.
• BMPs must be inspected in accordance with General Permit requirements for the associated
project type and risk level. It is recommended that at a minimum, BMPs be inspected
weekly, prior to forecasted rain events, daily during extended rain events, and after the
conclusion of rain events.
• Sample stormwater runoff required by the General Permit.
• Keep ample supplies of drip pans or absorbent materials onsite.
• Inspect and maintain machinery regularly to minimize leaks and drips.

Concrete Curing
Description and Purpose
Concrete curing is used in the construction of structures such as
bridges, retaining walls, pump houses, large slabs, and
structured foundations. Concrete curing includes the use of
both chemical and water methods.
Concrete and its associated curing materials have basic
chemical properties that can raise the pH of water to levels
outside of the permitted range. Discharges of storm water and
non-stormwater exposed to concrete during curing may have a
high pH and may contain chemicals, metals, and fines. The
General Permit incorporates Numeric Action Levels (NAL) for
pH (see Se~ction 2 of this handbook to determine your project's
risk level and if you are subject to these requirements).
Proper procedures and care should betaken when managing
concrete curing materials to prevent them from coming into
contact with stormwater flows, which could result in a high pH
discharge.
Suitable Applications
Suitable applications include all projects where Portland
Cement Concrete (PCC) and concrete curing chemicals are
placed where they can be exposed to rainfall, runoff from other
areas, or where runoff from the PCC will leave the site.
Limitations
• Runoff contact with concrete waste can raise pH levels in
the water to environmentally harmful levels and trigger
permit violations.

Concrete Finishing
Description and Purpose
Concrete finishing methods are used for bridge deck
rehabilitation, paint removal, curing compound removal, and
final surface finish appearances. Methods include sand
blasting, shot blasting, grinding, or high pressure water
blasting. Stormwater and non-stormwater exposed to concrete
finishing by-products may have a high pH and may contain
chemicals, metals, and fines. Proper procedures and
implementation of appropriate BMPs can minimize the impact
that concrete-finishing methods may have on stormwater and
non-stormwater discharges.
The General Permit incorporates Numeric.Action Levels (NAL)
for pH (see Section 2 of this handbook to determine your
project's risk level and if you are subject to these requirements).
Concrete and its associated curing materials have basic
chemical properties that can raise pH levels outside of the
permitted range. Additional care should be taken when
managing these materials to prevent them from coming into
contact with stormwater flows, which could lead to exceedances
of the General Permit requirements.
Suitable Applications
These procedures apply to all construction locations where
concrete finishing operations are performed.

Material Delivery and Storage WM-1
• Asphalt and concrete components
• Hazardous chemicals such as acids, lime, glues, adhesives, paints, solvents, and curing
compounds
• Concrete compounds
• Other materials that may be detrimental if released to the environment
Limitations
• Space limitation may preclude indoor storage.
11 Storage sheds often must meet building and fire code requirements.
Implementation
The following steps should be taken to minimize risk:
• Chemicals must be stored in water tight containers with appropriate secondary containment
or in a storage shed.
• When a material storage area is located on bare soil, the area should be lined and bermed.
• Use containment pallets or other practical and available solutions, such as storing materials
within newly constructed buildings or garages, to meet material storage requirements.
• Stack erodible landscape material on pallets and cover when not in use.
• Contain all fertilizers and other landscape materials when not in use.
• Temporary storage areas should be located away from vehicular traffic.
• Material Safety Data Sheets (MSDS) should be available on-site for all materials stored that
have the potential to effect water quality.
• Construction site areas should be designated for material delivery and storage.
• Material delivecy and storage areas should be located away from waterways, if possible.
Avoid transport near drainage paths or waterways.
Surround with earth berms or other appropriate containment BMP. See EC-9, Earth
Dike.sand Drainage Swales.
Place in an area that will be paved.
• Storage of reactive, ignitable, or flammable liquids must comply with the fire codes of your
area. Contact the local Fire Marshal to review site materials, quantities, and proposed
storage area to determine specific requirements. See the Flammable and Combustible
Liquid Code, NFP A.30.
• An up to date inventory of materials delivered and stored onsite should be kept.
November 2009 California Stormwater BMP Handbook
Construction

PA2017-045
Material Delivery and Storage WM-1
• Hazardous materials storage onsite should be minimized.
• Hazardous materials should be handled as infrequently as possible.
• Keep ample spill cleanup supplies appropriate for the materials being stored. Ensure that
cleanup supplies are in a conspicuous, labeled area.
• Employees and subcontractors should be trained on the proper material delivery and storage
practices.
• Employees trained in emergency spill cleanup procedures must be present when dangerous
materials or liquid chemicals are unloaded.
11 If significant residual materials remain on the ground after construction is complete,
properly remove and dispose of materials and any contaminated soil. See WM-7,
Contaminated Soil Management. If the area is to be paved, pave as soon as materials are
removed to stabilize the soil.
Material Storage Areas and Practices
• Liquids, petroleum products, and substances listed in 40 CFR Parts 110, 117, or 302 should
be stored in approved containers and drums and should not be overfilled. Containers and
drums should be placed in temporary containment facilities for storage.
• A temporary containment facility should provide for a spill containment volume able to
contain precipitation from a 25 year storm event, plus the greater of 10% of the aggregate
volume of all containers or 100% of the capacity of the largest container within its boundary,
whichever is greater.
• A temporary containment facility should be impervious to the materials stored therein for a
minimum contact time of 72 hours.
• A temporary containment facility should be maintained free of accumulated rainwater and
spills. in the event of spills or teaks, accumulated rainwater and spills should be collected
and placed into drums. These liquids should be handled as a hazardous waste unless testing
determines them to be non-hazardous. All collected liquids or non-hazardous liquids should
be sent to an approved disposal site.
• Sufficient separation should be provided between stored containers to allow for spill cleanup
and emergency response access.
• Incompatible materials, such as chlorine and ammonia, should not be stored in the same
temporary containment facility.
• Materials should be covered prior to, and during rain events.
• Materials should be stored in their original containers and the original product labels should
be maintained in place in a legible condition. Damaged or otherwise illegible labels should
be replaced immediately.

Material Delivery and Storage WM-1
• Bagged and boxed materials should be stored on pallets and should not be allowed to
accumulate on the ground. To provide protection from wind and rain throughout the rainy
season, bagged and boxed materials should be covered during non-working days and prior to
and during rain events.
• Stockpiles should be protected in accordance with WM-3, Stockpile Management.
• Materials should be stored indoors within existing structures or completely enclosed storage
sheds when available.
a Proper storage instructions should be posted at all times in an open and conspicuous
location.
• An ample supply of appropriate spill clean up material should be kept near storage areas.
• Also see WM-6, Hazardous Waste Management, for storing of hazardous wastes.
Material Delivery Practices
• Keep an accurate, up-to-date inventory of material delivered and stored onsite.
• Arrange for employees trained in emergency spill cleanup procedures to be present when
dangerous materials or liquid chemicals are unloaded.
Spill Cleanup
• Contain and clean up any spill immediately.
• Properly remove and dispose of any hazardous materials or contaminated soil if significant
residual materials remain on the ground after construction is complete. See WM-7,
Contaminated Soil Management.
• See WM-4, Spill Prevention and Control, for spills of chemicals and/or hazardous materials.
• ~ If spills or leaks of materials occur that are not contained and could discharge to surface
waters, non-visible sampling of site discharge may be required. Refer to the General Permit
or to your project specific Construction Site Monitoring Plan to determine if and where
sampling is required.
Cost
• The largest cost of implementation may be in the construction of a materials storage area
that is covered and provides secondary containment.
Inspection and Maintenance
• BMPs must be inspected in accordance with General Permit requirements for the associated
project type and risk level. It is recommended that at a minimum, BMPs be inspected
weekly, prior to forecasted rain events, daily during extended rain events, and after the
conclusion of rain events.
• Keep storage areas clean and well organized, including a current list of all materials onsite.
• Inspect labels on containers for legibility and accuracy.

Stockpile Management
Description and Purpose
Stockpile management procedures and practices are designed
to reduce or eliminate air and stormwater pollution from
stockpiles of soil, soil amendments, sand, paving materials such
as portland cement concrete (PCC) rubble, asphalt concrete
(AC), asphalt concrete rubble, aggregate base, aggregate sub
base or pre-mixed aggregate, asphalt minder (so called "cold
mix" asphalt), and pressure treated wood.
Suitable Applications
Implement in all projects that stockpile soil and other loose
materials.
Limitations 0
• Plastic sheeting as a stockpile protection is temporary and
hard to manage in windy conditions. Where plastic is used,
consider use of plastic tarps with nylon reinforcement
which may be more durable than standard sheeting.
• Plastic sheeting can increase runoff volume due to lack of
infiltration and potentially cause perimeter control failure.
• Plastic sheeting breaks down faster in sunlight.
• The use of Plastic materials and photodegradable plastics
should be avoided.
Implementation
Protection of stockpiles is a year-round requirement. To
properly manage stockpiles:

Stockpile Management WM-3
• On larger sites, a minimum of 50 ft separation from concentrated flows of stormwater,
drainage courses, and inlets is recommended.
• After 14 days of inactivity, a stockpile is non-active and requires further protection described
below. All stockpiles are required to be protected as non-active stockpiles immediately if
they are not scheduled to be used within 14 days.
• Protect all stockpiles from stormwater runon using temporary perimeter sediment barriers
such as compost berms (SE-13), temporary silt dikes (SE-12), fiber rolls (SE-5), silt fences
(SE-1), sandbags (SE-8), gravel bags (SE-6), or biofilter bags (SE-14). Refer to the individual
fact sheet for each of these controls for installation information.
• Implement wind erosion control practices as appropriate on all stockpiled material. For
specific information, see WE-1, Wind Erosion Control.
• Manage stockpiles of contaminated soil in accordance with WM-7, Contaminated Soil
Management.
• Place bagged materials on pallets and under cover.
• Ensure that stockpile coverings are installed securely to protect from wind and rain.
• Some plastic covers withstand weather and sunlight better than others. Select cover
materials or methods based on anticipated duration of use.
Protection of Non-Active Stockpiles
A stockpile is considered non-active if it either is not used for 14 days or if it is scheduled not to
be used for 14 days or more. Stockpiles need to be protected immediately if they are not
scheduled to be used within 14 days. Non-active stockpiles of the identified materials should be
protected as follows:
Soil stockpiles
• Soil ;tock.piles should be cov~red or protected with sa"il stabilization measure; and a
temporary perimeter sediment barrier at all times.
• Temporary vegetation should be considered for topsoil piles that will be stockpiled for
extended periods.
Stockpiles of Portland cement concrete rubble, asphalt concrete, asphalt concrete rubble,
aggregate base, or aggregate sub base
• Stockpiles should be covered and protected with a temporary perimeter sediment barrier at
all times.
Stockpiles of"cold mix"
• Cold mix stockpiles should be placed on and covered with plastic sheeting or comparable
material at all times and surrounded by a berm.

• Stockpiles of materials that may raise the pH of runoff (i.e., basic materials) should be
covered with plastic and surrounded by a berm.
Stockpiles/Storage of wood (Pressure treated with chromated copper arsenate or ammonia cal
copper zinc arsenate
• Treated wood should be covered with plastic sheeting or comparable material at all times
and surrounded by a berm.
Protection of Active Stockpiles
A stockpile is active when it is being used or is scheduled to be used within 14 days of the
previous use. Active stockpiles of the identified materials should be protected as follows:
• All stockpiles should be covered and protected with a temporary linear sediment barrier
prior to the onset of precipitation.
• Stockpiles of "cold mix" and treated wood, and basic materials should be placed on and
covered with plastic sheeting or comparable material and surrounded by a berm prior to the
onset of precipitation.
• The downstream perimeter of art active stockpile should be protected with a linear sediment
barrier or berm and runoff should be diverted around or away from the stockpile on the
upstream perimeter.
Costs
For cost information associated with stockpile protection refer to the individual erosion or
sediment control BMP fact sheet considered for implementation (For example, refer to SE-1 Silt
Fence for installation of silt fence around the perimeter of a stockpile.)
Inspection and Maintenance
• Stockpiles must be inspected in accordance with General Permit requirements for the
associated project type and risk level. It is recommended that at a minimum, BMPs be
0 inspected weekly, prior to forecasted rain eveftts, daily during extende'd rain events, and
after the conclusion of rain events.
• It may be necessary to inspect stockpiles covered with plastic sheeting more frequently
during certain conditions (for example, high winds or extreme heat).
• Repair and/or replace perimeter controls and covers as needed to keep them functioning
properly.
• Sediment shall be removed when it reaches one-third of the barrier height.

limitations
• In some cases it may be necessary to use a private spill cleanup company.
• This BMP applies to spills caused by the contractor and subcontractors.
• Procedures and practices presented in this BMP are general. Contractor should identify
appropriate practices for the specific materials used or stored onsite
Implementation
The following steps will help reduce the stormwater impacts of leaks and spills:
Education
• Be aware that different materials pollute in different amounts. Make sure that each
employee knows what a "significant spill" is for each material they use, and what is the
appropriate response for "significant" and "insignificant" spills.
• Educate employees and subcontractors on potential dangers to humans and the
environment from spills and leaks.
• Hold regular meetings to discuss and reinforce appropriate disposal procedures (incorporate
into regular safety meetings).
• Establish a continuing education program to indoctrinate new employees.
• Have contractor's superintendent or representative oversee and enforce proper spill
prevention ap.d control measures.
General}lfeasures
• To the extent that the work can be accomplished safely, spills of oil, petroleum products,
substances listed under 40 CFR parts 110,117, and 302, and sanitary and septic wastes
should be contained and cleaned up immediately.
• Store hazardous materials and wastes in covered containers and protect from vandalism.
• Place a stockpile of spill cleanup materials where it will be readily accessible.
• Train employees in spill prevention and cleanup.
• Designate responsible individuals to oversee and enforce control measures.
• Spills should be covered and protected from stormwater runon during rainfall to the extent
that it doesn't compromise clean up activities.
• Do not bury or wash spills with water.

Spill Prevention and C:ontrol WM-4
• Store and dispose of used clean up materials, contaminated materials, and recovered spill
material that is no longer suitable for the intended purpose in conformance with the
provisions in applicable BMPs.
• Do not allow water used for cleaning and decontamination to enter storm drains or
watercourses. Collect and dispose of contaminated water in accordance with WM-10, Liquid
Waste Management.
• Contain water overflow or minor water spillage and do not allow it to discharge into
drainage facilities or watercourses.
• Place proper storage, cleanup, and spill reporting instructions for hazardous materials
stored or used on the project site in an open, conspicuous, and accessible location.
• Keep waste storage areas clean, well organized, and equipped with ample cleanup supplies
as appropriate for the materials being stored. Perimeter controls, containment structures,
covers, and liners should be repaired or replaced as needed to maintain proper function.
Cleanup
11 Clean up leaks and spills immediately.
• Use a rag for small spills on paved surfaces, a damp mop for general cleanup, and absorbent
material for larger spills. If the spilled material is hazardous, then the used cleanup
materials are also hazardous and must be sent to either a certified laundry (rags) or disposed
of as hazardous waste.
• Never hose down or bury dry material spills. Clean up as much of the material as possible
and dispose ofproperly. See the waste management BMPs in this section for specific
information.
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.
• Absorbent materials should be promptly removed and disposed of properly.
• Follow the practice below for a minor spill:
Contain the spread of the spill.
Recover spilled materials.
Clean the contaminated area and properly dispose of contaminated materials.
Semi-Signtfi.cant Spills
• Semi-significant spills still 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.
January 2011 California Stormwater BMP Handbook
Construction
www ,casqa ,org
3 of 6
PA2017-045
Spill Prevention and Control WM-4
• Spills should be cleaned up immediately:
Contain spread of the spill.
Notify the project foreman immediately.
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 or hazardous spills that cannot be controlled by personnel in the immediate
vicinity, the following steps should be taken:
Notify the local emergency response by dialing 911. In addition to 911, the contractor Vvill
notify the proper county officials. It is the contractor's responsibility to have all
emergency phone numbers at the construction site.
Notify the Governor's Office of Emergency Services Warning Center, (916) 845-8911.
For spills of federal reportable quantities, in conformance with the requirements in 40
CFR parts 110,119, and 302, the contractor should notify the National Response Center
at (Boo) 424-8802.
Notification should first be made by telephone and followed up with a written report.
The services of a spills contractor or a Haz-Mat team should be obtained immediately.
Construction personnel should not attempt to clean up until the appropriate and
qualified staffs have 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, Cal/OSHA, etc.
Reporting
• Report significant spills to local agencies, such as the Fire Department; they can assist in
cleanup.
• Federal regulations require that any significant oil spill into a water body or onto an
adjoining shoreline be reported to the National Response Center (NRC) at 800-424-8802
(24 hours).
Use the following measures related to specific activities:

Vehicle and Equipment Maintenance
• If maintenance must occur onsite, use a designated area and a secondary containment,
located away from drainage courses, to prevent the runon of stormwater and the runoff of
spills.
• Regularly inspect onsite vehicles and equipment for leaks and repair immediately
• Check incoming vehicles and equipment (including delivery trucks, and employee and
subcontractor vehicles) for leaking oil and fluids. Do not allow leaking vehicles or
equipment onsite.
• Always use secondary containment, such as a drain pan or drop cloth, to catch spills or leaks
when removing or changing fluids.
• Place drip pans or absorbent materials under paving equipment when not in use.
• Use absorbent materials on small spills rather than hosing down or burying the spill.
Remove the absorbent materials promptly and dispose of properly.
111 Promptly transfer used fluids to the proper waste or recycling drums. Don't leave full drip
pans or other open containers lying around
• Oil filters disposed of in trashcans or dumpsters can leak oil and pollute stormwater. Place
the oil filter in a funnel over a waste oil-recycling drum to drain excess oil before disposal.
Oil filters can also be recycled. Ask the oil supplier or recycler about recycling oil filters.
• Store cracked batteries in a non-leaking secondary container. Do this with all cracked
batteries even if you think all the acid has drained out. If you drop a battery, treat it as if it is
cracked. Put it into the containment area until you are sure it is not leaking.
Vehicle and Equipment Fueling
• If fueling mu~t occur onsite, use designate areas, located away from drainage courses,. to
prevent the runon of stormwater and the runoff of spills.
• Discourage "topping off' of fuel tanks.
• Always use secondary containment, such as a drain pan, when fueling to catch spills/ leaks.
Costs
Prevention of leaks and spills is inexpensive. Treatment and/ or disposal of contaminated soil
or water can be quite expensive.
Inspection and Maintenance
• Inspect and verify that activity-based BMPs are in place prior to the commencement of
associated activities. While activities associated with the BMP are under way, inspect BMPs
in accordance with General Permit requirements for the associated project type and risk
level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted
rain events, daily during extended rain events, and after the conclusion of rain events.

Limitations
Temporary stockpiling of certain construction wastes may not necessitate stringent drainage
related controls during the non-rainy season or in desert areas with low rainfall.
Implementation
The following steps will help keep a clean site and reduce stormwater pollution:
• Select designated waste collection areas onsite.
• Inform trash-hauling contractors that you will accept only watertight dumpsters for onsite
use. Inspect dumpsters for leaks and repair any dumpster that is not watertight.
• Locate containers in a covered area or in a secondary containment.
• Provide an adequate number of containers with lids or covers that can be placed over the
container to keep rain out or to prevent loss of wastes when it is windy.
• Cover waste containers at the end of each work day and when it is raining.
• Plan for additional containers and more frequent pickup during the demolition phase of
construction.
• Collect site trash daily, especially during rainy and windy conditions.
• Remove this solid waste promptly since erosion and sediment control devices tend to co11ect
litter.
• Make sure that toxic liquid wastes (used oils, solvents, and paints) and chemicals (acids,
pesticides, additives, curing compounds) are not disposed of in dumpsters designated for
0 construction debris. 0 0 0
• Do not hose out dumpsters on the construction site. Leave dumpster cleaning to the trash
hauling contractor.
• Arrange for regular waste collection before containers overflow.
• Clean up immediately if a container does spill.
• Make sure that construction waste is collected, removed, and disposed of only at authorized
disposal areas.
Education
• Have the contractor's superintendent or representative oversee and enforce proper solid
waste management procedures and practices.
• Instruct employees and subcontractors on identification of solid waste and hazardous waste.
• Educate employees and subcontractors on solid waste storage and disposal procedures.

Solid Waste Management WM-5
• Hold regular meetings to discuss and reinforce disposal procedures (incorporate into regular
safety meetings).
• Require that employees and subcontractors follow solid waste handling and storage
procedures.
• Prohibit littering by employees, subcontractors, and visitors.
• Minimize production of solid waste materials wherever possible.
Collection, Storage, and Disposal
• Littering on the project site should be prohibited.
• To prevent clogging of the storm drainage system, litter and debris removal from drainage
grates, trash racks, and ditch lines should be a priority,
• Trash receptacles should be provided in the contractor's yard, field trailer areas, and at
locations where workers congregate for lunch and break periods.
• Litter from work areas ·within the construction limits of the project site should be collected
and placed in watertight dumpsters at least weekly, regardless of whether the litter was
generated by the contractor, the public, or others. Collected litter and debris should not be
placed in or next to drain inlets, stormwater drainage systems, or watercourses.
• Dumpsters of sufficient size and number should be provided to contain the solid waste
generated by the project.
• Full dumpsters should be removed from the project site and the contents should be disposed
of by the trash hauling contractor.
• Construction debris and waste should be removed from the site biweekly or more frequently
as needed.
• Construction material visible to the public should be stored or stacked in an orderly manner.
• Stormwater runon should 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 should be located at least 50 ft from drainage facilities and
watercourses and should not be located in areas prone to flooding or ponding.
• Except during fair weather, construction and highway planting waste not stored in
watertight dumpsters should be securely covered from wind and rain by covering the waste
with tarps or plastic.
• Segregate potentially hazardous waste from non~hazardous construction site waste.
• Make sure that toxic liquid wastes (used oils, solvents, and paints) and chemicals (acids,
pesticides, additives, curing compounds) are not disposed of in dumpsters designated for
construction debris.

PA2017-045
Solid Waste Management WM-5
• For disposal of hazardous waste, see 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 surplus building materials when
practical. For example, trees and shrubs from land clearing can be used as a brush barrier,
or converted into wood chips, then used as mulch on graded areas. Wood pallets, cardboard
boxes, and construction scraps can also be recycled.
Costs
All of the above are low cost measures.
Inspection and Maintenance
• Inspect and verify that activity-based BMPs are in place prior to the commencement of
associated activities. While activities associated with the BMP are under way, inspect BMPs
in accordance with General Permitrequirements for the associated project type and risk
level. It is recommended that at a minimum, BMPs be inspected weekly, prior to forecasted
rain events, daily during extended rain events, and aft~r the conclusion of rain events.
• Inspect BMPs subject to non-stormwater discharge daily while non-storm.water discharges
occur
• Inspect construction waste area regularly.
• Arrange for regular waste collection.

CONCRETE
WASHOUT
AREA
-----------~-----..--~~--~---------------------:--:-----·
Description and Purpose
Prevent the discharge of pollutants to storm water from
concrete waste by conducting washout onsite or offsite in a
designated area, and by employee and subcontractor training.
The General Permit incorporates Numeric Action Levels (NAL)
for pH (see Section 2 of this handbook to determine your
project's risk level and if you are subject to these requirements).
Many types of construction materials, including: mortar,
concrete, stucco, cement and block and their associated wastes
have basic chemical properties that call raise pH levels outside
of the permitted range. Additional care should be taken when
managing these materials to pre;ent them from coming into
contact with storm water flows and raising pH to levels outside
the accepted range.
Suitable Applications
Concrete waste management procedures and practices are
implemented on construction projects where:
• Concrete is used as a construction material or where
concrete dust and debris result from demolition activities.
• Slurries containing portland cement concrete (PCC) are
generated, such as from saw cutting, coring, grinding,
grooving, and hydro-concrete demolition.
• Concrete trucks and other concrete-coated equipment are
washed onsite.

• Mortar-mixing stations exist.
• Stucco mixing and spraying.
• See also NS-8, Vehicle and Equipment Cleaning.
Limitations
• Offsite washout of concrete wastes may not always be possible.
• Multiple washouts may be needed to assure adequate capacity and to allow for evaporation.
Implementation
The following steps will help reduce stormwater pollution from concrete wastes:
• Incorporate requirements for concrete waste management into material supplier and
subcontractor agreements.
• Store dry and wet materials under cover, away from drainage areas. Refer to WM-1, Material
Delivery and Storage for more information.
11 Avoid mixing excess amounts of concrete.
• Perform washout of concrete trucks in designated areas only, where washout will not reach
stormwater.
• Do not wash out concrete trucks into storm drains, open ditches, streets, streams or onto the
ground. Trucks should always be washed out into designated facilities.
• Do not allow excess concrete to be dumped onsite, except in designated areas.
• For onsite washout:
On larger sites, it4s recommended to locate washout areas at least .. 50 feet from storm
drains, open ditches, or water bodies. Do not allow runoff from this area by constructing
a temporary pit or bermed area large enough for liquid and solid waste.
Washout wastes into the temporary washout where the concrete can set, be broken up,
and then disposed properly.
Washouts shall be implemented in a manner that prevents leaching to unclerlying soils.
Washout containers must be water tight and washouts on or in the ground must be lined
with a suitable impervious liner, typically a plastic type material.
• Do not wash sweepings from exposed aggregate concrete into the street or storm drain.
Collect and return sweepings to aggregate base stockpile or dispose in the trash.
• See typical concrete washout installation details at the end of this fact sheet.
Education
• Educate employees, subcontractors, and suppliers on the concrete waste management
techniques described herein.
July 2012 California Stormwater BMP Handbook
Construction

PA2017-045
Concrete Waste Management WM-8
• Arrange for contractor's superintendent or representative to oversee and enforce concrete
waste management procedures.
• Discuss the concrete management techniques described in this BMP (such as handling of
concrete waste and washout) with the ready-mix concrete supplier before any deliveries are
made.
Concrete Demolition Wastes
• Stockpile concrete demolition waste in accordance with BMP WM-3, Stockpile Management.
11 Dispose of or recycle hardened concrete waste in accordance with applicable federal, state or
local regulations.
Concrete Slurry Wastes
• PCC and AC waste should not be allowed to enter storm drains or watercourses.
• PCC and AC waste should be collected and disposed of or placed in a temporary concrete
washout facility (as described in Onsite Temporary Concrete Washout Facility, Concrete
Transit Truck Washout Procedures, below).
• A foreman or construction supervisor should monitor onsite concrete working tasks, such as
saw cutting, coring, grinding and grooving to ensure proper methods are implemented.
11 Saw-cut concrete slurry should not be allowed to enter storm drains or watercourses.
Residue from grinding operations should be picked up by means of a vacuum attachment to
the grinding machine or by sweeping. Saw cutting residue should not be allowed to flow
across the pavement and should not be left on the surface of the pavement. See also NS-3,
Paving and Grinding Operations; and WM-10, Liquid Waste Management.
• Concrete slurry residue should be disposed in a temporary washout facility (as described in
Onsite Temporary Concrete Washout Facility, Concrete Transit Truck Washout Procedures,
below) and allowed to dry. Dispose of dry slurry residue in accordance with WM-5, SoJid
Waste Management.
Onsite Temporary Concrete Washout Facility, Transit Truck Washout
Procedures
• Temporary concrete washout facilities should be located a minimum of 50 ft from storm
drain inlets, open drainage facilities, and watercourses. Each facility should be located away
from construction traffic or access areas to prevent disturbance or tracking.
• A sign should be installed adjacent to each washout facility to inform concrete equipment
operators to utilize the proper facilities.
• Temporary concrete washout facilities should be constructed above grade or below grade at
the option of the contractor. Temporary concrete washout facilities should be constructed
and maintained in sufficient quantity and size to contain all liquid and concrete waste
generated by washout operations.
July 2012 California Stormwater BMP Handbook

PA2017-045
Concrete Waste Management WM-8
• Temporary washout facilities should have a temporary pit or bermed areas of sufficient
volume to completely contain all liquid and waste concrete materials generated during
washout procedures.
• Temporary washout facilities should be lined to prevent discharge to the underlying ground
or surrounding area.
• Washout of concrete trucks should be performed in designated areas only.
• Only concrete from mixer truck chutes should be washed into concrete wash out.
• Concrete washout from concrete pumper bins can be washed into concrete pumper trucks
and discharged into designated washout area or properly disposed of or recycled offsite.
• Once concrete wastes are washed into the designated area and allowed to harden, the
concrete should be broken up, removed, and disposed of per WM-5, Solid Waste
Management. Dispose of or recycle hardened concrete on a regular basis.
• Temporary Concrete Washout Facility (Type Above Grade)
Temporary concrete washout facility (type above grade) should be constructed as shown
on the details at the end of this BMP, with a recommended minimum length and
minimum width of 10 ft; however, smaller sites or jobs may only need a smaller washout
facility. With any washout, always maintain a sufficient quantity and volume to contain
all liquid and concrete waste generated by washout operations.
Materials used to construct the washout area should conform to the provisions detailed
in their respective BMPs (e.g., SE~8 Sandbag Barrier).
Plastic lining material should be a minimum of 10 mil in polyethylene sheeting and
should be free of holes, tears, or other defects that compromise the impermeability of the
material.
Alternatively, portable removable containers can be used as above grade concrete
washouts. Also called a "roll-off'; this concrete washout facility should be properly
sealed to prevent leakage, and should be removed from the site and replaced when the
container reaches 75% capacity.
• Temporary Concrete Washout Facility (Type Below Grade)
Temporary concrete washout facilities (type below grade) should be constructed as
shown on the details at the end of this BMP, with a recommended minimum length and
minimum width of 10 ft. The quantity and volume should be sufficient to contain all
liquid and concrete waste generated by washout operations.
Lath and flagging should be commercial type.
Plastic lining material should be a minimum of 10 mil polyethylene sheeting and should
be free of holes, tears, or other defects that compromise the impermeability of the
material.

Concrete Waste Management WM-8
The base of a washout facility should be free of rock or debris that may damage a plastic
liner.
Removal ofTemporary Concrete Washout Facilities
• When temporary concrete washout facilities are no longer required for the work, the
hardened concrete should be removed and properly disposed or recycled in accordance with
federal, state or local regulations. Materials used to construct temporary concrete washout
facilities should be removed from the site of the work and properly disposed or recycled in
accordance with federal, state or local regulations ..
• Holes, depressions or other ground disturbance caused by the removal of the temporary
concrete washout facilities should be backfilled and repaired.
Costs
All of the above are low cost measures. Roll-off concrete washout facilities can be more costly
than other measures due to removal and replacement; however, provide a cleaner alternative to
traditional washouts. The type of washout facility, size, and availability of materials will
determine the cost of the washout.
Inspection and Maintenance
11 BMPs must be inspected in accordance with General Permit requirements for the associated
project type and risk level. It is recommended that at a minimum, BMPs be inspected
weekly, prior to forecasted rain events, daily during extended rain events, and after the
conclusion of rain events.
• Temporary concrete washout facilities should be maintained to provide adequate holding
capacity with a minimum freeboard of 4 in. for above grade facilities and 12 in. for below
grade facilities. Maintaining temporary concrete washout facilities should include removing
and disposing of hardened concrete and returning the facilities to a functional condition.
Hardened concrete materials should be removed and properly disposed or recycled in
accordance with federal, state or local regulations.
~ ~
• Washout facilities must be cleaned, or new facilities must be constructed and ready for use
once the washout is 75% full.
• Inspect washout facilities for damage (e.g. torn liner, evidence ofleaks, signage, etc.). Repair
all identified damage.

Sanitary /Septic WastE! Management WM-9
Description and Purpose
Proper sanitary and septic waste management prevent the
discharge of pollutants to storm water from sanitary and septic
waste by providing convenient, well-maintained facilities, and
arranging for regular service and disposal.
Suitable Applications
Sanitary septic waste management practices are suitable for use
at all construction sites that use temporary or portable sanitary
and septic waste systems.
Limitations
None identified.
Implementation
Sanitary or septic wastes should be treated or disposed of in
accordance with state and local requirements. In many cases,
one contract with a local facility supplier will be all that it takes
to make sure sanitary wastes are properly disposed.
Storage and Disposal Procedures
• Temporary sanitary facilities should be located away from
drainage facilities, watercourses, and from traffic
circulation. If site conditions allow, place portable facilities
a minimum of 50 feet from drainage conveyances and
traffic areas. When subjected to high winds or risk of high
winds, temporary sanitary facilities should be secured to
prevent overturning.

pollutants to the stormwater drainage system of the receiving water.
• Consider safety as well as environmental implications before placing temporary sanitary
facilities.
• Wastewater should not be discharged or buried within the project site.
• Sanitary and septic systems that discharge directly into sanitary sewer systems, where
permissible, should comply with the local health agency, city, county, and sewer district
requirements.
• Only reputable, licensed sanitary and septic waste haulers should be used.
• Sanitary facilities should be located in a convenient location.
• Temporary septic systems should treat wastes to appropriate levels before discharging.
• If using an onsite disposal system (OSDS), such as a septic system, local health agency
requirements must be followed.
• Temporary sanitary facilities that discharge to the sanitary sewer system should be properly
connected to avoid illicit discharges.
• Sanitary and septic facilities should be maintained in good working order by a licensed
service.
• Regular waste collection by a licensed hauler should be arranged before facilities overflow.

ANNUAL REPORT
DESCRIPTION OF BASIC ANALYTICAL PARAMETERS
The Industrial Activities Storm Water General Permit (General Permit) requires you to analyze storm water samples for at least
four parameters. These are pH, Total Suspended Solids (TSS), Specific Conductance (SC),and Total Organic Carbon (TOG).
Oil and Grease (O&G) may be substituted for TOG. In addition, you must monitor for any other pollutants which you believe to be
present in your storm water discharge as a result of industrial activity and analytical parameters listed in Table D of the General
Permit. There are no numeric limitations for the parameters you test for.
The four parameters which the General Penn it requires to be tested are considered indicator parameters. In other words,
regardless of what type of facility you operate, these parameters are nonspecific and general enough to usually provide some
indication whether pollutants are present in your storm water discharge. The following briefly explains what each of these
parameters mean:
pH is a numeric measure of the hydrogen-ion concentration. The neutral, or acceptable, range is within 6.5 to 8.5. At values less
than 6.5, the water is considered acidic; above 8.5 it is considered alkaline or basic. An example of an acidic substance is vinegar,
and a alkaline or basic substance is liquid antacid. Pure rainfall tends to have a pH of a little Jess than 7. There may be sources of
materials or industrial activities which could increase or decrease the pH of your storm water discharge. If the pH levels of your
storm water discharge are high or low, you should conduct a thorough evaluation of all potential pollutant sources at your site.
Total Suspended Solids {TSS) is a measure of the undissolved solids that are present in your storm water discharge. Sources
of TSS include sediment from erosion of exposed land, and dirt from impervious (i.e. paved) areas. Sediment by itself can be very
toxic to aquatic life because it covers feeding and breeding grounds, and can smother organisms living on the bottom of a water
body. Toxic chemicals and other pollutants also adhere to sediment particles. This provides a medium by which toxic or other
pollutants end up in our water ways and ultimately in human and aquatic life. TSS levels vary in runoff from undisturbed land. It
has been shown that TSS levels increase significantly due to land development.
Specific Conductance (SC} is a numerical expression of the ability of the water to carry an electric current. SC can be used to
assess the degree of mineralization, salinity, or estimate the total dissolved solids concentration of a water sample. Because of
air pollution, most rain water has a SC a little above zero. A high SC could affect the usability of waters for drinking, irrigation, and
other commercial or industrial use.
Total Organic Carbon (TOC) is a measure of the total organic matter present in water. (All organic matter contains carbon)
This test is sensitive and able to detect small concentrations of organic matter. Organic matter is naturally occurring in animals,
plants, and man. Organic matter may .also be man made (so called synthetic organics). Synthetic organics include pesticides,
fuels, solvents, and paints. Natural organic matter utilizes the oxygen in a receiving water to biodegrade. Too much organic
matter could place a significant oxygen demand on the water, and possibly impact its quality. Synthetic organics either do not
biodegrade or biodegrade very slowly. Synthetic organics are a source of toxic ·chemicals that can have adverse affects at very
low concentrations. Some of these chemicals bioaccumufate in aquatic life. If your levels of TOG are high, you should evaluate
all sources of natural or synthetic organics you may use at your site.
Oil and Grease (O&G) is a measure of the amount of oil and grease present in your storm water discharge. At very low
concentrations, O&G can cause a sheen (that floating "rainbow") on the surface of water (1 qt. of oil can pollute 250,000 gallons of
water). O&G can adversely affect aquatic life and create unsightly floating material and film on wa.ter, thus making it undrinkable.
Sources of O&G include maintenance shops, vehicles, machines and roadways.
If you have any questions regarding whether or not your consmuent concentrations are too high, please contact your local
Regional Board office. The United States Environmental Protection Agency {USEPA) has published stormwater discharge
benchmarks for a number of parameters. These benchmarks may be helpful when evaluating whether additional BMPs are
appropriate. These benchmarks can be accessed at our website at http://www.swrcb.ca.gov. It is. contained in the Sampling and
Analysis Reduction Certification.
