Section 3. Nature of activity
GENERAL SITE INFORMATION
The first stage of construction of Belvedere Block 10 proposed the construction of 40 attached townhouse units and 28 single
family detached units (plus 2 existing single family detached units). The total permitted site area is 93.61 acres and the
estimated area to be disturbed is 19.56 acres.
The site consists of moderate tree cover with virgin soil terrain. The property is bounded by South Fork Rivanna River to the
east, Belvedere Phase 5 to the south west, Belvedere Phase 2B to the west and Dunlora Farm to the southwest and southeast.
Steep slopes (preserved) and Steep slopes (managed) per Albemarle County GIS does exist on the north east side of the site.
The areas where construction activities occur near preserved steep slopes, tree protection and silt fence will be installed as a
protective barrier, as to not disturb the slopes.
SEQUENCE OF MAJOR ACTIVITIES
Phase 1
1.1 Install the construction entrance at site entrance off of Fowler Street. Should the temporary construction entrance not be
maintained properly or an excessive amount of soil be tracked onto the public roadway, then a paved construction
entrance, water tanker truck with two pressure washers, and settling area may be required by the Erosion and Sediment
Control Program Administrator.
1.2 Place silt fence, tree protection, and other perimeter controls. Clearing and grubbing shall first be limited to that necessary
to install the perimeter controls.
1.3 Install sediment traps 1 through 7. Provide stabilization measures to all traps.
1.4 Contractor to construct diversion dikes to direct runoff to the sediment traps. Contractor to ensure a positive slope is
maintained. Berm shall be stabilized as a first step in disturbance.
1.5 Once all the Phase 1 controls are installed, and prior to additional clearing and grubbing, the contractor shall coordinate
inspections, as required by the County of Albemarle.
1.6 Clear and grub the remainder of the project area. The land disturbance shall be restricted to the limits of disturbance
shown in the approve Erosion Control Plans.
Phase 2
2.1 Strip topsoil and stockpile within an area on the property at a location approved by Albemarle County Community
Development. Install silt fence at the perimeter of the stockpile(s).
2.2 Construction of the walls may begin. Muck out, fill, and close sediment traps that interfere with wall construction and
divert water to a neighboring sediment trap. Relocate sediment trap 1, sediment trap 4, and sediment trap 7.
2.3 Contractor to bring site up to grade as shown on the phase 2 Erosion and Sediment Control Plan. Construction road
stabilization may be required.
2.4 Permanent soil stabilization shall be applied to all denuded areas within seven days after final grade is reached on any
portion of the site. Temporary soil stabilization shall be applied within seven days to denuded areas that may not be a final
grade but will remain dormant for longer than 30 days. Permanent stabilization shall be applied to areas that are to be left
dormant for more than one year. Lime, fertilize, and apply temporary or permanent seeding to all denuded areas immediately
after achieving final grade. All permanent slopes steeper than 3:1 shall receive stabilization with landscaping vegetation
hardier than grass, which will not require mowing.
Phase 3
3.1 Contractor to begin construction on all utilities. All inlets must be protected by inlet protection as shown on sheet 14 of the
ESC plans
3.2 Fine grade and install curbing, roads, and lots. Muck out, fill, and close traps once water is flowing to the inlets and
through the stormwater pipes. Sediment trap 4 to remain until phase 4.
Phase 4
4.1 Spread topsoil and add permanent seeding to disturbed area.
4.2 After site is stabilized and permission is obtained from the Erosion control inspector, remove silt fencing and other
remaining erosion control measures if deemed appropriate by Albemarle County.
4.3 Demobilize.

Section 4. Erosion and Sediment Control Plan.
(Provide a reduced, I Ix17 copy of the latest Erosion and Sediment Control Plan. Do not reference only.)
Approved erosion and sediment control plans for Belvedere Phase 3 Block 10 are incorporated by reference as part of this
Stormwater Pollution Prevention Plan. Approved plans are included in this SWPPP binder.
1. The purpose of the erosion control measures shown on these plans shall be to preclude the transport of all waterbome
sediments resulting from construction activities from entering onto adjacent properties of state waters. If field
inspection reveals the inadequacy of the plan to confine sediment to the project site, appropriate modifications will be
made to correct any plan deficiencies. In addition to these notes, all provisions of the Virginia Erosion and Sediment
Control Regulations shall apply to this project.
2. All erosion and sediment control measures shall be installed and maintained in accordance with the Virginia Erosion
and sediment Control Handbook (31 Edition, 1992) and Virginia Regulations 9VAC25-840 Erosion and Sediment
control Regulations. The contractor shall be thoroughly familiar with all applicable measures contained therein which
may be pertinent to this project.
3. All points of construction ingress and egress shall be protected by a construction entrance to prevent tracking of mud
onto public right-of-way. An entrance permit from VDOT is required prior to any construction activities within state
rights -of -way. Where sediment is transported onto a public road surface, the road shall be thoroughly cleaned at the
end of each day. Sediment shall be removed from the roads by shoveling or sweeping and transported to a sediment
control disposal area. Street washing shall be allowed only after sediment is removed in this manner.
4. A copy of the approved erosion and sediment control plan shall be maintained on the site at all times.
5. Sediment basins and traps, perimeter dikes, sediment barriers, and other measures intended to trap sediment onsite
must be constructed as a first step in grading and be made functional before upslope land disturbance takes place.
Earthen structures such as dams, dikes, and diversions must be seeded and mulched immediately after installation.
Periodic inspections of the erosion control measures shall be made to assess their condition. Any necessary
maintenance of the measures shall be accomplished immediately upon notification by the SWPPP Inspector and shall
include the repair of measures damaged by any subcontractor including those of the public utility companies.
6. Sediment traps and sediment basin shall be designed and constructed based upon the total drainage area to be served
by the trap or basin.
a. The minimum storage capacity of a sediment trap shall be 134 cubic yards per acre of drainage area and the trap
shall only control drainage areas less than three acres (see sizing table for dimensions).
b. Surface runoff from disturbed areas that is comprised of flow from drainage areas greater than or equal to three
acres shall be controlled by a sediment basin. The minimum storage capacity of a sediment basin shall be 134
cubic yards per acre of drainage area. The outfall system shall, at a minimum, maintain the structural integrity of
the basin during a twenty -five-year storm of 24-hour duration. Runoff coefficients used in runoff calculations
shall correspond to a bare earth condition or those conditions expected to exist while the sediment basin is
utilized.
7. The contractor is responsible for installation of any additional erosion control measures necessary to prevent erosion
and sedimentation as determined by the plan approving authority.
Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County
8. All disturbed areas are to drain to approved sediment control measures at all times during all land disturbing activities
and during site development until final stabilization is achieved.
9. Sediment control measures may require minor field adjustments at time of construction to ensure their intended
purpose is accomplished. Division of code compliance approval will be required for other deviations from the
approved plans.
10. Concentrated runoff shall not flow down cut or fill slopes unless contained within an adequate temporary or
permanent channel, flume or slope drain structure.
11. The contractor shall place soil stockpiles at the locations shown on the SWPPP plan sheet for each area of
construction, or as directed by design engineer. During construction, soil stockpiles shall be stabilized or protected
with sediment trapping measures immediately. Offsite waste or borrow areas shall be approved by the division of
code compliance prior to the import of any borrow or export of any waste to or from the project.
12. Prior to commencing land disturbing activities in areas other than indicated on these plans (including, but not limited
to, offsite borrow or waste areas), the contractor shall submit a supplementary erosion control plan to the owner for
review and approval by the plan approving authority.
13. Permanent or temporary soil stabilization must be applied to all denuded areas within 7 days after final grade is
reached on any portion of the site. Temporary soil stabilization shall be applied within seven days to denuded areas
that may not be at final grade but will remain dormant for longer than 14 days. Permanent stabilization shall be
applied to areas that are to be left dormant for more than one year. Soil stabilization measures include vegetative
establishment, mulching and the early application of gravel base material on areas to be paved. Contractor shall
establish a stabilized site and not allow any erosion or sediment to exit.
14. If disturbed area stabilization is to be accomplished during the months of November, December, January or February,
stabilization shall be accomplished by permanently seeding the area with a seeding mixture that includes the seasonal
nurse crop for the Piedmont area, which is Winter Rye. See Table 3.32-D for a list of site -specific seeding mixtures
for the Piedmont area. This is in accordance with Specification 3.32 from the Virginia Erosion and Sediment Control
Handbook (VESCH). The seeding area will also need to be mulched in order to assist the growth of the seeding in the
winter months (Specification 3.35 of the VESCH). For temporary seeding stabilization during these months, a 50150
mix of annual ryegrass and winter ryegrass, as well as a mulching cover should be put down according to
Specification 3.31 of the VESCH, Table 3.31-B.
15. The term seeding, final vegetative cover or stabilization, on this plan shall mean the successful germination and
establishment of a stable grass cover from a properly prepared seedbed containing the specified amounts of seed,
lime, and fertilizing in accordance with Specification 3.32, permanent seeding. Irrigation shall be required as
necessary to ensure establishment of grass cover.
16. Underground utility lines (water, sewer, power, cable, or gas) shall be installed in accordance with the following
standards in addition to other applicable criteria.
a. No more than 500 linear feet of trench may be opened at one time.
b. Excavated material shall be placed on the uphill side of trenches.
c. Effluent from dewatering operations shall be filtered or passed through an approved sediment trapping device, or
both and discharged in a manner that does not adversely affect flowing streams or off -site property.
d. Material used for back filling trenches shall be properly compacted in order to minimize erosion and promote
stabilization.
e. Re -stabilization shall be accomplished in accordance with these regulations.
f. Applicable safety regulations shall be complied with.
Issued — 10/2014 Stormwater Pollution Prevention Plan (S WPPP) Albemarle County
17. Cut and fill slopes shall be designed and constructed in a manner that will minimize erosion. Slopes that re found to
be eroding excessively within one year of permanent stabilization shall be provided with additional slope stabilizing
measures until the problem is resolved.
18. All storm sewer inlets that are made during construction shall be protected so that sediment -laden water cannot enter
the conveyance system without first being filtered or otherwise treated to remove sediment.
19. Before newly constructed storm water conveyance channels or pipes are made operational, adequate outlet protection
and any required temporary or permanent channel lining shall be installed in both the conveyance channel and
receiving channel.
20. All temporary erosion and sediment control measures shall be removed within 30 days after final site stabilization or
after the temporary measures are no longer needed, unless otherwise authorized by the local program administrator.
Trapped sediment and disturbed soil areas resulting from the disposition of temporary measures shall be permanently
stabilized to prevent further erosion and sedimentation.

C.NON-STORMWATER DISCHARGES
It is expected that the following non-stormwater discharges will occur from the site during the construction period.
1. Waters used to wash vehicles or equipment where soaps, solvents, or detergents have not been used and the wash
water has been filtered, settled, or similarly treated prior to discharge.
2. Water used to control dust that has been filtered, settled, or similarly treated prior to discharge.
3. Potable water sources, including uncontaminated waterline flushing'stfire flow analysis.
4. Routine external building wash down where soaps, solvents or detergents have not been used and the wash water
has been filtered, settled, or similarly treated prior to discharge.
5. Pavement wash waters where spills or leaks of toxic or hazardous materials have not occurred (or where all
spilled or leaked material has been removed prior to washing); where soaps, solvents, or detergents have not been
used; and where the wash water has been filtered, settled, or similarly treated prior to discharge.
6. Foundation or footing drains where flows are not contaminated with process materials such as solvents.
7. Uncontaminated excavation dewatering, including dewatering of trenches and excavations that have been filtered,
settled, or similarly treated prior to discharge.
8. Landscape irrigation.
All non-stormwater discharges will be directed to sediment control measures prior to discharge.

F. POLLUTION PREVENTION AWARENESS
Material Management Practices/Spill Prevention:
The following are the materials management practices that will be used to reduce the risk of spills or other accidental
exposure of materials and substances to stormwater runoff.
(a) Employee Training:
Employee training with regard to material management practices is conducted at the site. Training includes
discussions of spill response, good housekeeping, and other material management practices. Employee
training generally occurs with each new employee once hired by the site contractor. Weekly tailgate training
meetings are advised to ensure that as the site evolves and changes employees are up to date on all PPP
practices. A training log to document these meetings can be found in Section 13. Additional Information and
Logs.
(b) Good Housekeeping:
The following good housekeeping practices will be followed onsite during the construction project.
1. All materials stored onsite will be stored in a neat, orderly manner in their appropriate containers.
Materials which have the potential for contaminating runoff during storm events will be stored in
their appropriate watertight containers, stored under a canopy, tarpaulin, shrink wrapped or
otherwise precluded from direct exposure of precipitation.
2. Empty containers that may contain chemical residues shall be disposed of in accordance with State
and Local regulations.
3. Products, where possible, will be kept in their original containers with the original manufacture's
label.
4. Chemical or petroleum products will not be mixed with one another unless recommended by the
manufacturer.
5. Whenever possible, all of a product will be used up before disposing of the container.
6. Manufacturer's recommendations for proper use and disposal will be followed.
7. The site superintendent will inspect daily to ensure proper use and disposal of materials onsite

Hazardous Products:
These practices are used to reduce the risk associated with hazardous materials. Hazardous waste to include oil
filters, petroleum products, paint, curing compounds and equipment maintenance fluids.
1. Products will be kept in original containers unless they are not re -sealable.
2. Products will be stored in structurally sound and sealed containers and segregated from other non -waste
materials.
3. Original specimen labels and materials safety data sheets will be kept on file; they contain important product
information.
4. If surplus product must be disposed of, manufacturers and/or local and State recommended methods for
proper disposal will be followed.
Product Specific Practices:
The following product specific practices will be followed onsite:
(a) Petroleum Products:
1. All onsite vehicles will be monitored for fluid leaks and will receive regular preventive
maintenance to reduce the chance of leakage.
2. It is recommended that, if practicable, all refueling, repair and changing of equipment and vehicle
fluids shall be conducted in a designated area, with the use of either spill buckets and/or fuel spill
mats to reduce the potential for contamination. This area will be designed in a manner to reduce
the potential for contamination of onsite resources. For refueling, repair and changing of
equipment and vehicle fluids outside of the designated areas, care should be taken to avoid
activities within +/- 50 feet of wetlands, streams, water bodies, tree preservation areas or any
other environmentally sensitive areas.
3. Petroleum products will be stored in tightly sealed containers which are clearly labeled.
4. An area will be designated for the collection and storage of all chemical and storage of all
chemical and petroleum -based products and containers for those products. The containers shall be
protected from rain events. These areas are identified on the SWPPP/PPP Reference Drawing
included in this section.
5. Any asphalt substances used onsite will be applied according to the manufacturer's
recommendations.
6. The project superintendent will regularly inspect the site to ensure proper disposal methods of
used antifreeze, oils, filters and other hazardous materials are followed.
(b) Fertilizers:
Fertilizers used will be applied according to manufacturer's product standards. The contents of any partially
used bags of fertilizer will be transferred to a sealable plastic container to avoid spills.
(c) Paints, Curing Compounds, Soaps, Solvents, and Detergents:
All containers will be tightly sealed and stored when not required for use. Excess paint will be properly
disposed of according to manufacturers' instructions or State and local regulations. Discharges of soaps,
solvents and detergents are prohibited.
(d) Concrete Trucks and Wash Water from Construction Materials and Vehicles:
Issued — 10/2014 Stormwater Pollution Prevention Plan (S WPPP) Albemarle County
Concrete trucks will only wash out or discharge surplus concrete or drum wash water at approved locations in
accordance with State and local regulations. Wash water must be directed into a leak proof container or leak-
proof settling basin that is properly designed. The liquid and hardened concrete must then be handled and
disposed of properly and is not to be discharged. Washout areas are identified on the SWPPP/PPP Reference
Drawing included in this section. An EPA concrete washout fact -sheet is provided in Section 13. Water from
vehicle wash stations (if needed) is to be directed to the nearest trap as shown on the approved erosion and
sediment control plan before discharged.
(e) Solid Waste:
All waste materials will be collected and disposed of into a metal trash dumpster in the staging area.
Dumpsters will have a secure watertight lid, be placed away from stormwater conveyances and drains, and
meet all local and state solid -waste management regulations. Only trash and construction debris from the site
will be deposited in the dumpsters. All personnel will be instructed, during tailgate training sessions,
regarding the correct procedure for disposal of trash and construction debris. Notices that state these practices
will be posted in the office trailer and the individual who manages day-to-day site operations will be
responsible for seeing that these practices are followed
(f) Sanitary Waste:
Portable lavatories are located on -site and are serviced on a regular basis by a contractor. They will be located
in up -land areas away from direct contact with surface waters. Any spills occurring during servicing will be
cleaned up immediately, including any contaminated soils, and disposed of according to all federal, state, and
local regulations.

discharge of sewage, industrial waste, other wastes or any noxious or deleterious substance or a
hazardous substance or oil in an amount equal to or in excess of a reportable quantity established
under either 40 CFR Part 110, 40 CFR Part 117, 40 CFR Part 302, or § 62.1-44.34:19 of the Code
of Virginia that occurs during a 24-hour period into or upon surface waters or who discharges or
causes or allows a discharge that may reasonably be expected to enter surface waters, shall
notify the Department of Environmental Quality of the discharge immediately upon discovery of
the discharge, but in no case later than within 24 hours after said discovery. A written report of
the unauthorized discharge shall be submitted to the department and the VSMP authority within
five days of discovery of the discharge. The written report shall contain:
1. A description of the nature and location of the discharge;
2. The cause of the discharge;
Page 20 of 26
3. The date on which the discharge occurred;
4. The length of time that the discharge continued;
5. The volume of the discharge;
6. If the discharge is continuing, how long it is expected to continue;
7. If the discharge is continuing, what the expected total volume of the discharge will be; and
Any steps planned or taken to reduce, eliminate and prevent a recurrence of the present
discharge or any future discharges not authorized by this general permit.
Discharges reportable to the department and the VSMP authority under the immediate reporting
requirements of other regulations are exempted from this requirement.
H. Reports of unusual or extraordinary discharges. If any unusual or extraordinary discharge
including a "bypass" or "upset," as defined in this general permit, should occur from a facility and
the discharge enters or could be expected to enter surface waters, the operator shall promptly
notify, in no case later than within 24 hours, the department and the VSMP authority by telephone
after the discovery of the discharge. This notification shall provide all available details of the
incident, including any adverse effects on aquatic life and the known number of fish killed. The
operator shall reduce the report to writing and shall submit it to the department and the VSMP
authority within five days of discovery of the discharge in accordance with Part III 12. Unusual
and extraordinary discharges include any discharge resulting from:
1. Unusual spillage of materials resulting directly or indirectly from processing operations;
2. Breakdown of processing or accessory equipment;
3. Failure or taking out of service of some or all of the facilities; and
4. Flooding or other acts of nature.
I. Reports of noncompliance. The operator shall report any noncompliance which may adversely
affect surface waters or may endanger public health.
An oral report to the department and the VSMP authority shall be provided within 24 hours
from the time the operator becomes aware of the circumstances. The following shall be
included as information that shall be reported within 24 hours under this subdivision:
a. Any unanticipated bypass; and
b. Any upset that causes a discharge to surface waters.
2. A written report shall be submitted within five days and shall contain:
a. A description of the noncompliance and its cause;
Page 21 of 26
b. The period of noncompliance, including exact dates and times, and if the noncompliance
has not been corrected, the anticipated time it is expected to continue; and
c. Steps taken or planned to reduce, eliminate, and prevent reoccurrence of the
noncompliance.
The department may waive the written report on a case -by -case basis for reports of
noncompliance under Part III I if the oral report has been received within 24 hours and no
adverse impact on surface waters has been reported.
3. The operator shall report all instances of noncompliance not reported under Part III 1 1 or 2 in
writing as part of the SWPPP. The reports shall contain the information listed in Part 111 1 2.
NOTE: The reports required in Part III G, H and I shall be made to the department and the VSMP
authority. Reports may be made by telephone, email, or by fax. For reports outside normal working
hours, leaving a recorded message shall fulfill the immediate reporting requirement. For
emergencies, the Virginia Department of Emergency Management maintains a 24-hour telephone
service at 1-800-468-8892.
4. Where the operator becomes aware of a failure to submit any relevant facts, or submittal of
incorrect information in any report, including a registration statement, to the department or the
VSMP authority, the operator shall promptly submit such facts or correct information.
J. Notice of planned changes.
1. The operator shall give notice to the department and the VSMP authority as soon as possible
of any planned physical alterations or additions to the permitted facility or activity. Notice is
required only when:
a. The operator plans an alteration or addition to any building, structure, facility, or installation
that may meet one of the criteria for determining whether a facility is a new source in
9VAC25-870-420;
b. The operator plans an alteration or addition that would significantly change the nature or
increase the quantity of pollutants discharged. This notification applies to pollutants that
are not subject to effluent limitations in this general permit; or
2. The operator shall give advance notice to the department and VSMP authority of any planned
changes in the permitted facility or activity, which may result in noncompliance with state
permit requirements.
K. Signatory requirements.
1. Registration statement. All registration statements shall be signed as follows:
a. For a corporation: by a responsible corporate officer. For the purpose of this chapter, a
responsible corporate officer means: (i) a president, secretary, treasurer, or vice-president
of the corporation in charge of a principal business function, or any other person who
performs similar policy -making or decision -making functions for the corporation; or (ii) the
manager of one or more manufacturing, production, or operating facilities, provided the
Page 22 of 26
manager is authorized to make management decisions that govern the operation of the
regulated facility including having the explicit or implicit duty of making major capital
investment recommendations, and initiating and directing other comprehensive measures
to assure long-term compliance with environmental laws and regulations; the manager
can ensure that the necessary systems are established or actions taken to gather
complete and accurate information for state permit application requirements; and where
authority to sign documents has been assigned or delegated to the manager in
accordance with corporate procedures;
b. For a partnership or sole proprietorship: by a general partner or the proprietor,
respectively; or
c. For a municipality, state, federal, or other public agency: by either a principal executive
officer or ranking elected official. For purposes of this chapter, a principal executive officer
of a public agency includes (i) the chief executive officer of the agency or (ii) a senior
executive officer having responsibility for the overall operations of a principal geographic
unit of the agency.
2. Reports and other information. All reports required by this general permit, including SWPPPs,
and other information requested by the board or the department shall be signed by a person
described in Part III K 1 or by a duly authorized representative of that person. A person is a
duly authorized representative only if:
a. The authorization is made in writing by a person described in Part III K 1;
b. The authorization specifies either an individual or a position having responsibility for the
overall operation of the regulated facility or activity such as the position of plant manager,
operator of a well or a well field, superintendent, position of equivalent responsibility, or
an individual or position having overall responsibility for environmental matters for the
operator. (A duly authorized representative may thus be either a named individual or any
individual occupying a named position); and
c. The signed and dated written authorization is included in the SWPPP. A copy shall be
provided to the department and VSMP authority, if requested.
3. Changes to authorization. If an authorization under Part III K 2 is no longer accurate because
a different individual or position has responsibility for the overall operation of the construction
activity, a new authorization satisfying the requirements of Part III K 2 shall be submitted to
the VSMP authority as the administering entity for the board prior to or together with any
reports or information to be signed by an authorized representative.
4. Certification. Any person signing a document under Part III K 1 or 2 shall make the following
certification:
"I certify under penalty of law that I have read and understand this document and that this
document and all attachments were prepared in accordance with a system designed to assure
that qualified personnel properly gathered and evaluated the information submitted. Based on
my inquiry of the person or persons who manage the system, or those persons directly
responsible for gathering the information, the information submitted is, to the best of my
knowledge and belief, true, accurate, and complete. I am aware that there are significant
Page 23 of 26
penalties for submitting false information, including the possibility of fine and imprisonment for
knowing violations."
L. Duty to comply. The operator shall comply with all conditions of this general permit. Any state
permit noncompliance constitutes a violation of the Virginia Stormwater Management Act and the
Clean Water Act, except that noncompliance with certain provisions of this general permit may
constitute a violation of the Virginia Stormwater Management Act but not the Clean Water Act.
Permit noncompliance is grounds for enforcement action; for state permit coverage, termination,
revocation and reissuance, or modification; or denial of a state permit renewal application.
The operator shall comply with effluent standards or prohibitions established under § 307(a)
of the Clean Water Act for toxic pollutants within the time provided in the regulations that establish
these standards or prohibitions or standards for sewage sludge use or disposal, even if this
general permit has not yet been modified to incorporate the requirement.
M. Duty to reapply. If the operator wishes to continue an activity regulated by this general permit
after the expiration date of this general permit, the operator shall submit a new registration
statement at least 60 days before the expiration date of the existing general permit, unless
permission for a later date has been granted by the board. The board shall not grant permission
for registration statements to be submitted later than the expiration date of the existing general
permit.
N. Effect of a state permit. This general permit does not convey any property rights in either real
or personal property or any exclusive privileges, nor does it authorize any injury to private property
or invasion of personal rights, or any infringement of federal, state or local law or regulations.
O. State law. Nothing in this general permit shall be construed to preclude the institution of any
legal action under, or relieve the operator from any responsibilities, liabilities, or penalties
established pursuant to any other state law or regulation or under authority preserved by § 510 of
the Clean Water Act. Except as provided in general permit conditions on "bypassing" (Part III U)
and "upset' (Part III V), nothing in this general permit shall be construed to relieve the operator
from civil and criminal penalties for noncompliance.
P. Oil and hazardous substance liability. Nothing in this general permit shall be construed to
preclude the institution of any legal action or relieve the operator from any responsibilities,
liabilities, or penalties to which the operator is or may be subject under §§ 62.1-44.34:14 through
62.1-44.34:23 of the State Water Control Law or § 311 of the Clean Water Act.
Q. Proper operation and maintenance. The operator shall at all times properly operate and
maintain all facilities and systems of treatment and control (and related appurtenances), which
are installed or used by the operator to achieve compliance with the conditions of this general
permit. Proper operation and maintenance also includes effective plant performance, adequate
funding, adequate staffing, and adequate laboratory and process controls, including appropriate
quality assurance procedures. This provision requires the operation of back-up or auxiliary
facilities or similar systems, which are installed by the operator only when the operation is
necessary to achieve compliance with the conditions of this general permit.
R. Disposal of solids or sludges. Solids, sludges or other pollutants removed in the course of
treatment or management of pollutants shall be disposed of in a manner so as to prevent any
pollutant from such materials from entering surface waters and in compliance with all applicable
state and federal laws and regulations.
Page 24 of 26
S. Duty to mitigate. The operator shall take all steps to minimize or prevent any discharge in
violation of this general permit that has a reasonable likelihood of adversely affecting human
health or the environment.
T. Need to halt or reduce activity not a defense. It shall not be a defense for an operator in an
enforcement action that it would have been necessary to halt or reduce the permitted activity in
order to maintain compliance with the conditions of this general permit.
U. Bypass.
1. 'Bypass," as defined in 9VAC25-870-10, means the intentional diversion of waste streams
from any portion of a treatment facility. The operator may allow any bypass to occur that does
not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to
ensure efficient operation. These bypasses are not subject to the provisions of Part III U 2 and
3.
2. Notice.
a. Anticipated bypass. If the operator knows in advance of the need for a bypass, the
operator shall submit prior notice to the department, if possible at least 10 days before the
date of the bypass.
b. Unanticipated bypass. The operator shall submit notice of an unanticipated bypass as
required in Part III I.
3. Prohibition of bypass.
a. Except as provided in Part III U 1, bypass is prohibited, and the board or department may
take enforcement action against an operator for bypass unless:
(1) Bypass was unavoidable to prevent loss of life, personal injury, or severe property
damage. Severe property damage means substantial physical damage to property,
damage to the treatment facilities that causes them to become inoperable, or
substantial and permanent loss of natural resources that can reasonably be expected
to occur in the absence of a bypass. Severe property damage does not mean
economic loss caused by delays in production;
(2) There were no feasible alternatives to the bypass, such as the use of auxiliary
treatment facilities, retention of untreated wastes, or maintenance during normal
periods of equipment downtime. This condition is not satisfied if adequate back-up
equipment should have been installed in the exercise of reasonable engineering
judgment to prevent a bypass that occurred during normal periods of equipment
downtime or preventive maintenance; and
(3) The operator submitted notices as required under Part III U 2.
b. The department may approve an anticipated bypass, after considering its adverse effects,
if the department determines that it will meet the three conditions listed in Part III U 3 a.
Page 25 of 26
V. Upset.
1. An "upset," as defined in 9VAC25-870-10, means an exceptional incident in which there is
unintentional and temporary noncompliance with technology -based state permit effluent
limitations because of factors beyond the reasonable control of the operator. An upset does
not include noncompliance to the extent caused by operational error, improperly designed
treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or
careless or improper operation.
2. An upset constitutes an affirmative defense to an action brought for noncompliance with
technology -based state permit effluent limitations if the requirements of Part III V 4 are met.
A determination made during administrative review of claims that noncompliance was caused
by upset, and before an action for noncompliance, is not a final administrative action subject
to judicial review.
3. An upset does not include noncompliance to the extent caused by operational error,
improperly designed treatment facilities, inadequate treatment facilities, lack of preventative
maintenance, or careless or improper operation.
4. An operator who wishes to establish the affirmative defense of upset shall demonstrate,
through properly signed, contemporaneous operating logs or other relevant evidence that:
a. An upset occurred and that the operator can identify the cause of the upset;
b. The permitted facility was at the time being properly operated;
c. The operator submitted notice of the upset as required in Part III I; and
d. The operator complied with any remedial measures required under Part III S.
5. In any enforcement proceeding, the operator seeking to establish the occurrence of an upset
has the burden of proof.
W. Inspection and entry. The operator shall allow the department as the board's designee, the
VSMP authority, EPA, or an authorized representative of either entity (including an authorized
contractor), upon presentation of credentials and other documents as may be required by law to:
1. Enter upon the operator's premises where a regulated facility or activity is located or
conducted, or where records shall be kept under the conditions of this general permit;
2. Have access to and copy, at reasonable times, any records that shall be kept under the
conditions of this general permit;
3. Inspect and photograph at reasonable times any facilities, equipment (including monitoring
and control equipment), practices, or operations regulated or required under this general
permit; and
4. Sample or monitor at reasonable times, for the purposes of ensuring state permit compliance
or as otherwise authorized by the Clean Water Act or the Virginia Stormwater Management
Act, any substances or parameters at any location.
Page 26 of 26
For purposes of this section, the time for inspection shall be deemed reasonable during regular
business hours, and whenever the facility is discharging. Nothing contained herein shall make an
inspection unreasonable during an emergency.
X. State permit actions. State permit coverage may be modified, revoked and reissued, or
terminated for cause. The filing of a request by the operator for a state permit modification,
revocation and reissuance, or termination, or a notification of planned changes or anticipated
noncompliance does not stay any state permit condition.
Y. Transfer of state permit coverage.
1. State permits are not transferable to any person except after notice to the department. Except
as provided in Part III Y 2, a state permit may be transferred by the operator to a new operator
only if the state permit has been modified or revoked and reissued, or a minor modification
made, to identify the new operator and incorporate such other requirements as may be
necessary under the Virginia Stormwater Management Act and the Clean Water Act.
As an alternative to transfers under Part III Y 1, this state permit may be automatically
transferred to a new operator if:
a. The current operator notifies the department at least 30 days in advance of the proposed
transfer of the title to the facility or property;
b. The notice includes a written agreement between the existing and new operators
containing a specific date for transfer of state permit responsibility, coverage, and liability
between them; and
c. The department does not notify the existing operator and the proposed new operator of
its intent to modify or revoke and reissue the state permit. If this notice is not received, the
transfer is effective on the date specified in the agreement mentioned in Part III Y 2 b.
3. For ongoing construction activity involving a change of operator, the new operator shall accept
and maintain the existing SWPPP, or prepare and implement a new SWPPP prior to taking
over operations at the site.
Z. Severability. The provisions of this general permit are severable, and if any provision of this
general permit or the application of any provision of this state permit to any circumstance, is held
invalid, the application of such provision to other circumstances and the remainder of this general
permit shall not be affected thereby.

Procedure for Spills of Non -Reportable Quantities
Most spills can be cleaned up following manufacturer specifications. Absorbentloil dry, sealable containers, plastic bag and
shovelstbrooms are suggested minimum spill response items that should be available at this location.
1) Check for hazards (flammable material, noxious fumes, cause of spill)- if flammable liquid, turn off engines and
nearby electrical equipment. If serious hazards are present, leave the area and call 911.
2) Make sure the spill area is safe to enter and that it does not pose an immediate threat to health or safety of any person.
3) Stop the spill source.
4) Call co-workers and supervisor for assistance and to make them aware of the spill and potential dangers.
5) If possible, stop spill from entering drains (use absorbent or other material as necessary)
6) Stop spill from spreading (use absorbent or other material)
7) If spill material has entered a stone sewer; contact locality's storm sewer water department and locality's VSMP
inspector.
8) Clean up spilled material and do not flush area with water.
9) Properly dispose of cleaning materials and used absorbent material according to manufacturer specifications.

Description of Concrete Washout at
Construction Sites
Concrete and its ingredients
Concrete is a mixture of cement, water, and aggregate material.
Portland cement is made by heating a mixture of limestone and
clay containing oxides of calcium, aluminum, silicon and other
metals in a kiln and then pulverizing the resulting clinker. The
fine aggregate particles are usually sand. Coarse aggregate
is generally gravel or crushed stone. When cement is mixed
with water, a chemical reaction called hydration occurs, which
produces glue that binds the aggregates together to make
concrete.
Concrete washout
After concrete is poured at a construction site, the chutes of
ready mixed concrete trucks and hoppers of concrete pump
trucks must be washed out to remove the remaining concrete
before it hardens. Equipment such as wheelbarrows and hand
tools also need to be washed down. At the end of each work
day, the drums of concrete trucks must be washed out. This is
customarily done at the ready mixed batch plants, which are
usually off -site facilities, however large or rural construction
projects may have on -site batch plants. Cementitious (having
the properties of cement) washwater and solids also come from
using such construction materials as mortar, plaster, stucco,
and grout.
Environmental and Human Health I
Concrete washout water (or washwater) is a slurry containing
toxic metals. It's also caustic and corrosive, having a pH
near 12. In comparison, Drano liquid drain cleaner has a pH
of 13.5. Caustic washwater can harm fish gills and eyes and
interfere with reproduction. The safe pH ranges for aquatic life
habitats are 6.5 — 9 for freshwater and 6.5 — 8.5 for saltwater.
Construction workers should handle wet concrete and
washout water with care because it may cause skin irritation
and eye damage. If the washwater is dumped on the ground
(Fig. 1), it can run off the construction site to adjoining roads
and enter roadside storm drains, which discharge to surface
waters such as rivers, lakes, or estuaries. The red arrow in
Figure 2 points to a ready mixed truck chute that's being
washed out into a roll -off bin, which isn't watertight. Leaking
washwater, shown in the foreground, will likely follow similar
Figure 1. Chute
washwater being dumped
on the ground
Figure 2. Chute
washwater leaking from a
roll -off bin being used as a
washout container
paths to nearby surface waters. Rainfall may cause concrete
washout containers that are uncovered to overflow and also
transport the washwater to surface waters. Rainwater polluted
with concrete washwater can percolate down through the
soil and alter the soil chemistry, inhibit plant growth, and
contaminate the groundwater. Its high pH can increase
the toxicity of other substances in the surface waters and
soils. Figures 1 and 2 illustrate the need for better washout
management practices.
Best Management Practice Objectives
The best management practice objectives for concrete washout
are to (a) collect and retain all the concrete washout water and
solids in leak proof containers, so that this caustic material
does not reach the soil surface and then migrate to surface
waters or into the ground water, and (b) recycle 100 percent
of the collected concrete washout water and solids. Another
objective is to support the diversion of recyclable materials from contacted to inquire
landfills. Table 1 shows how concrete washout materials can be
recycled and reused.

Washwater recycling, treatment, disposal
Washwater from concrete truck
chutes, hand mixers, or other
equipment can be passed through
a system of weirs or filters to remove
solids and then be reused to wash
down more chutes and equipment
at the construction site or as an
ingredient for making additional
concrete. A three chamber washout
filter is shown in Figure 3. The first
stage collects the coarse aggregate.
The middle stage filters out the
small grit and sand. The third stage
has an array of tablets that filter
Figure 3. Concrete washout
filter
out fines and reduces the pH. The filtered washwater is then
discharged through a filter sock. An alternative is to pump the
washout water out of the washout container (Fig 4) and treat
the washwater off site to remove metals and reduce its pH,
so it can be delivered to a publicly owned treatment works
(POTW), also known as a municipal wastewater treatment plant,
which provides additional treatment allowing the washwater
to be discharged to a surface water. The POTW should be
about any pretreatment
requirements, i.e., the
National Pretreatment
Standards for Prohibited
Dischargers (40CFR 403.5)
before discharging the
washwater to the POTW.
The washwater can also
be retained in the washout
container and allowed to

washout container for treatment and reuse
evaporate, leaving only the hardened cementitious solids to be
recycled.
Solids recycling
The course aggregate materials that are washed off concrete
truck chutes into a washout container can be either separated
by a screen and placed in aggregate bins to be reused at
the construction site or returned to the ready mixed plant and
washed into a reclaimer (Fig. 5). When washed out into a
reclaimer, the fine and course aggregates are separated out
and placed in different
piles or bins to be reused
in making fresh concrete.
Reclaimers with settling
tanks separate cement
fines from the washwater,
and these fines can also
be used in new concrete
unless prohibited by the
user's concrete quality
specifications.

Hardened concrete recycling
When the washwater in a construction site concrete washout
container has been removed or allowed to evaporate, the
hardened concrete that remains can be crushed (Fig. 6)
and reused as a construction material. It makes an excellent
aggregate for road base and can be used as fill at the
Figure 6. Crushed concrete stockpile and
crusher
construction site or
delivered to a recycler.
Concrete recyclers can
be found at municipal
solid waste disposal
facilities, private
recycling plants, or large
construction sites.
Wet concrete recycling
Builders often order a little more ready mixed concrete than
they actually need, so it is common for concrete trucks to
have wet concrete remaining in their drum after a delivery. This
unused concrete can be returned to the ready mixed plant and
either (1) used to pour precast concrete products (e.g., highway
barriers, retaining wall blocks, riprap), (2) used to pave the
ready mixed plant's yard, (3) washed into a reclaimer, or
(4) dumped on an impervious surface and allowed to harden,
so it can be crushed and recycled as aggregate. Unused wet
concrete should not be dumped on bare ground to harden at
construction sites because this can contribute to ground water
and surface water contamination.
Washout Containers
Different types of washout containers are available for
collecting, retaining, and recycling the washwater and solids
from washing down mixed truck chutes and pump truck
hoppers at construction sites.
Chute washout box
A chute washout box is mounted on the back of the ready
mixed truck. If the truck has three chutes, the following
procedure is used to perform the washout from the top down:
(1) after the pour is completed, the driver attaches the extension
chute to the washout box, (2) the driver then rotates the main
chute over the extension chute (Fig. 7) and washes down the
hopper first then the main chute, (3) finally the driver washes
down the flop down chute and last the extension chute hanging
on the box. All washwater and solids are captured in the box.
Figure 7. Chute washout box
After the wash down,
washwater and solids are
returned to the ready mixed
plant for recycling. A filter
basket near the top of the
washout box separates out
the coarse aggregates so
they can be placed in a
bin for reuse either at the
construction site or back at
the cement plant.
Chute washout bucket and pump
After delivering ready mixed concrete and scraping the last of
the customer's concrete down the chute, the driver hangs a
washout bucket shown in Figure 8 (see red arrow) on the end of
the truck's chute and secures the hose to insure no leaks. The
driver then washes down
the chute into the bucket to
remove any cementitious
material before it hardens.
After washing out the chute,
the driver pumps (yellow
arrow points to the pump)
the washwater, sand, and
other fine solids from the
bucket up into the truck's
drum to be returned to the
Figure B. Chute washout bucket and
PUMP
ready mixed plant, where it can be washed into a reclaimer.
A removable screen at the bottom of the washout bucket
prevents course aggregate from entering the pump. This
course aggregate can also be returned to the plant and added
to the coarse aggregate pile to be reused. All the materials are
recycled.
Hay bale and plastic washout pit
A washout pit made with hay bales and a plastic lining is shown
in Figure 9. Such pits can be dug into the ground or built above
grade. The plastic lining should be free of tears or holes that
would allow the washwater to escape (Fig. 10). After the pit is
used to wash down the chutes of multiple ready mixed trucks
and the washwater has evaporated or has been vacuumed off,
the remaining hardened solids can be broken up and removed
from the pit. This process may damage the hay bales and
plastic lining. If damage occurs, the pit will need to be repaired
and relined with new plastic. When the hardened solids are
removed, they may be bound up with the plastic lining and have
to be sent to a landfill, rather than recycled. Recyclers usually
accept only unmixed material. If the pit is going to be emptied
and repaired more than a few times, the hay bales and plastic
will be generating additional solid waste. Ready mixed concrete

trucks can use hay bale washout pits, but concrete pump
trucks have a low hanging hopper in the back that may prevent
their being washed out into bale -lined pits.
Vinyl washout container
The vinyl washout
container (Fig. 11) is
portable, reusable, and
easier to install than a
hay bale washout pit.
The biodegradable filter
Figure 11. Vinyl washout pit with filter bag
bag (Fig. 12) assists in
extracting the concrete solids and prolongs the life of the vinyl
container. When the bag is lifted, the water is filtered out and
the remaining concrete solids and the bag can be disposed of
together in a landfill, or the hardened concrete can be delivered
to a recycler. After the solids have been removed several times
and the container is full of washwater, the washwater can be
allowed to evaporate, so the container can be reused. The
washwater can be removed more quickly by placing another
filter bag in the container
and spreading water gelling
granules evenly across the
water. In about five minutes,
the water in the filter bag will
turn into a gel that can be
removed with the bag. Then
the gel and filter bag can be
disposed to together.
Metal washout container
Figure 12. Extracting the concrete
solids or gelled washwater
The metal roll -off bin (Fig. 13) is designed to securely contain
concrete washwater and solids and is portable and reusable.
It also has a ramp that allows concrete pump trucks to wash
out their hoppers (Fig. 14). Roll -off providers offer recycling
services, such as, picking up the roll -off bins after the
washwater has evaporated and the solids have hardened,
replacing them with
empty washout bins, and
delivering the hardened
concrete to a recycler
(Fig. 15), rather than a
landfill. Some providers will
vacuum off the washwater,
treat it to remove metals and
reduce the pH, deliver it to a
wastewater treatment plant
for additional treatment and

Another metal, portable, washout container, which has a
rain cover to prevent overflowing, is shown in Figure 16. It is
accompanied by an onsite washwater treatment unit, which
reduces the pH and uses a forced weir tank system to remove
the coarse aggregate, fine aggregate, and cement fines. The
washwater can
then be reused at

Sitinq Washout Facilities
Concrete washout facilities, such as washout pits and vinyl
or metal washout containers, should be placed in locations
that provide convenient access to concrete trucks, preferably
near the area where concrete is being poured. However they

should not be placed within 50 feet of storm drains, open
ditches, or waterbodies. Appropriate gravel or rock should
cover approaches to concrete washout facilities when they are
located on undeveloped property. On large sites with extensive
concrete work, washouts should be placed at multiple locations
for ease of use by ready mixed truck drivers. If the washout

Operating and Inspecting Washout www.concreterecycling.org
Facilities
Concrete washout facilities should be inspected daily and after
heavy rains to check for leaks, identify any plastic linings and
sidewalls have been damaged by construction activities, and
determine whether they have been filled to over 75 percent
capacity. When the washout container is filled to over
75 percent of its capacity, the washwater should be vacuumed
off or allowed to evaporate to avoid overflows. Then when the
remaining cementitious solids have hardened, they should be
removed and recycled. Damages to the container should be
repaired promptly. Before heavy rains, the washout container's
liquid level should be lowered or the container should be
covered to avoid an overflow during the rain storm.
Educating Concrete Subcontractors
The construction site superintendent should make ready mixed
truck drivers aware of washout facility locations and be watchful
for improper dumping of cementitious material. In addition,
concrete washout requirements should be included in contracts
with concrete delivery companies.
