ADDITIONAL STORMWATER POLLUTION PREVENTION
MEASURES
VEHICLE & EQUIPMENT MAINTENANCE
uescnption ana rurpose
Prevent or reduce the contamination of stormwater resulting from vehicle and equipment maintenance by running a
"dry clean site ". The best option would be to perform maintenance activities at an off site facility. If this option
is not available, then work should be performed in designated areas only, while providing cover for materials stored
outside, checking for leaks and spills, and containing and cleaning up spills immediately.
Suitable Applications
These procedures are suitable on all construction projects where an onsite yard area is necessary for storage and
maintenance of heavy equipment and vehicles.
Limitations
Onsite vehicle and equipment maintenance should only be used where it is impractical to send equipment and
vehicles off site for maintenance and repair. Sending vehicles /equipment offsite should be done in conjunction
with a Stabilized Construction Entrance /Exit. Outdoor vehicle and equipment maintenance is a potentially
significant source of stormwater pollution. Activities that can contaminate stormwater include engine repair and
service, changing or replacement of fluids, and outdoor equipment storage and parking (engine fluid leaks).
Implementation
If maintenance must occur onsite, use designated areas, located away from drainage courses. Dedicated
maintenance areas should be protected from stormwater runon and runoff, and should be located at least 50 ft.
from downstream drainage facilities and watercourses.
Drip pans or absorbent pads should be used during vehicle and equipment maintenance work that involves fluids,
unless the maintenance work is performed over an impermeable surface in a dedicated maintenance area.
Place a stock pile of spill cleanup materials where it will be readily accessible.
All fueling trucks and fueling areas are required to have spill kits and /or use other spill protection devices.
Use absorbent materials on small spills. Remove the absorbent materials promptly and dispose of properly.
Inspect onsite vehicles and equipment daily at start up for leaks, and repair immediately.
Keep vehicles and equipment clean, do not allow excessive build -up of oil and grease.
re to and roc wastes
cle
Seg ga y such as greases used for oil or oil filters, antifreeze, cleaning solutions, automotive
batteries, hydraulic and transmission fluids. Provide secondary containment and covers for these materials if
stored onsite.
Train employees and subcontractors in proper fueling and clean up procedures.
Nozzles used in vehicle and equipment fueling should be equipped with an automatic shutoff to control drips.
Fueling operations should not be left unattended.
Federal, state, and local governments should be observed for any stationary above ground storage tanks.
Inspection and Maintenance
Vehicles and equipment should be inspected each day of use for leaks. Leaks should be repaired immediately or
problem vehicles or equipment should be removed from the project site.
Keep ample supplies of spill cleanup materials onsite.
Immediately clean up spills and properly dispose of contaminated soil and cleanup materials.
SOLID WASTE MANAGEMENT
Description and Purpose
Solid waste management procedures and practices are designed to prevent or reduce the discharge of pollutants
to stormwater from solid or construction waste by providing designated waste collection areas and containers,
arranging for regular disposal, and training employees and subcontractors.
Suitable Applications
This BMP is suitable for construction sites where the following wastes are generated or stored:
Solid waste generated from trees and shrubs removed during land clearing, demolition of existing structures
(rubble), and building construction.
Packaging materials including wood, paper, and plastic.
Scrap or surplus building materials including scrap metals, rubber, plastic, glass pieces and masonry.
Domestic wastes including food containers such as beverage cans, coffee cups, paper bags, plastic wrappers, and
cigarettes.
Construction wastes including brick, mortar, timber, steel and metal scraps, pipe and electrical cuttings,
nonhazardous equipment parts, stryrofoam and other materials send transport and package construction materials.
Implementation
The following steps will help keep a clean site and reduce stormwater pollution:
Select designated waste collection areas on site.
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.
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.
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 collect 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 construction debris.
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.
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 the construction limits of the project 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.
Inspection and Maintenance
Inspect and verify that activity -based BMP's are in place prior to the commencement of associated activities. While
activities associated with the BMP are under way, inspect weekly to verify continued BMP implementation.
Inspect BMP's subject to non - stormwater discharge daily while non - stormwater discharges occur.
Inspect construction waste areas regularly.
Arrange for regular waste collection.
CONCRETE WASHOUT
The following steps will help reduce stormwater pollution from concrete wastes:
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.
Incorporate requirements for concrete waste management into material supplier and subcontractor agreements.
Store dry and wet materials under cover, away from drainage areas.
Avoid mixing excess amounts of fresh concrete.
Perform washout of concrete trucks offsite or in desinnated areas only.
Do not washout concrete trucks into storm drains, open ditches, streets, or streams.
Do not allow excess concrete to be dumped onsite, except in designated areas.
For onsite washout:
- Locate washout area at least 50 ft. from storm drains, open ditches, or water bodies.
- Do not allow ronoff from this area by constructing a temporary pit or bermed area
large enough for liquid and solid waste.
- Wash out wastes into the temporary pit where concrete can set, be broken up, and then
disposed properly.
- Avoid creating runoff by draining water to a bermed or level area when washing concrete
to remove fine particles and expose the aggregate.
- 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.
DEWATERING AND PUMPING OPERATIONS
Description and Purpose
Dewatering operations are practices that manage the discharge of pollutants when non - stormwater and accumulated
precipitation must be removed from a work location so that construction work may be accomplished.
Suitable Applications
The practices are implemented for discharges or non - stormwater from construction sites. Non - stormwaters include,
but are not limited to, groundwater, water from cofferdams, water diversions, and waters used during construction
activities that must be removed from a work area. Practices identified in this section are also appropriate for
implementation when managing the removal of accumulated precipitation (stormwater) from depressed areas at a
construction site.
Limitations
Site conditions will dictate design and use of dewatering operations. The controls discussed in this best
management practice (BMP) address sediment only. The controls detailed in this BMP only allow for minimal settling
time for sediment particles. Use only when site conditions restrict the use of the other control methods.
Dewatering operations will require, and must comply with, applicable local permits.
Implementation
Dewatering discharges must not cause erosion at the discharge point. A variety of methods can be used to treat
water during dewatering operations. Several devices are presented below and provide options to achieve sediment
removal. The size of particles present in the sediment and Permit or receiving water limitations on sediment are
key considerations for selecting sediment treatment option(s); in some cases, the use of multiple devices may be
appropriate.
SEDIMENT BASIN
Description:
A sediment basin is a temporary basin with a controlled release structure that is formed by excavation or
construction of an embankment to detain sediment -laden runoff and allow sediment to settle out before discharging.
Sediment basins are generally larger than Sediment Traps.
Appropriate Applications:
Effective for the removal of gravel, sand, silt, some metals that settle out with the sediment, and trash.
Implementation:
Excavation and construction of related facilities is required.
Temporary sediment basins must be fenced if safety is a concern.
Outlet protection is required to prevent erosion at the outfall location.
Maintenance:
Maintenance is required for safety fencing, vegetation, embankment, inlet and outfall structures, as well as other
features.
Removal of sediment is required when the storage volume is reduced by one -half.
SEDIMENT TRAP
Description:
A sediment trap is a temporary basin formed by excavation and /or construction of an earthen embankment across a
waterway or low drainage area to detain sediment -laden runoff and allow sediment to settle out before discharging.
Sediment traps are generally smaller than Sediment Basins.
Appropriate Applications:
Effective for the removal of large and medium sized particles (sand and gravel) and some metals that settle out
with the sediment.
Implementation:
Excavation and construction of related facilities is required.
Trap inlets should be located to maximize the travel distance to the trap outlet.
Use rock or vegetation to protect the trap outlets against erosion.
Maintenance:
Maintenance is required for vegetation, embankment, inlet and outfall structures, as well as other features.
Removal of sediment is required when the storage volume is reduced by one - third.
GRAVITY BAG FILTER
Description:
A gravity bag filter, also referred to as a dewatering bag is a square or rectangular bag made of non -woven
geotextile fabric that collects sand, silt, and fines.
Appropriate Applications:
Effective for the removal of sediments (gravel, sand, and silt). Some metals are removed with the sediment.
Implementations:
Water is pumped into one side of the bag and seeps through the bottom and sides of the bag.
A secondary barrier, such as a rock filter bed or straw /hay bale barrier, is placed beneath and beyond the edges of
the bag to capture sediments that escape the bag.
Maintenance:
Inspection of the flow conditions, bag condition, bag capacity, and the secondary barrier is required.
Replace the bag when it no longer filters sediment or passes water at a reasonable rate. The bag is disposed of
offsite.
FLOOD & SOILS MAP
SCALE: NONE
MmB2 - Miami Silt loam, Soil Description and Characteristics:
The main soil features that adversely affect engineering uses of this soil are moderate
potential frost action, moderate shrink -swell potential, moderate permeability and
low strength. In addition, erosion is a hazard during construction. This soil is suitable
for building sites, but slope, clayey texture, shrinking and swelling, and low strength
are moderate limitations that need to be overcome. This soil has severe limitations for
local roads and streets because of low strength. The base material for roads and
streets should be replaced or strengthened with suitable material.
CrA - Crosby silt loam, Soil Description and Characteristic:
The main soil features that adversely affect engineering uses of this soil are a seasonal
high water t ab le high potential
frost action, moderate shrink -swell potential and
moderate permeability. This soil has severe limitations for building sites. The site needs
to be artificially drained to prevent wetness from becoming a problem. Dwellings
with basements should not be constructed on this soil. This soil has severe limitations
for local roads and streets because of seasonal high water table and high potential
frost action. The base material for roads and streets should be replaced or
strengthened with suitable material.
Recommendations and methods to overcome soil limitations:
Limitations for local roads, streets and dwellings because of seasonal high water table
and high potential frost action can be overcome by the use of curb underdrains,
sub -base strengthening, or lime stabilization. Swales which sever the surface drainage
can also help. High water tables can be overcome with respect to basement
construction with the use of perimeter foundation drains and sump pumps. Refer to
the site condition drawings and details for specific information related to the
proposed infrastructure improvements on this site.
