Section 3. Nature of activity
GENERAL SITE INFORMATION
This project proposes to build a driveway access across two live streams with prefabricated bridges. There is to be no
disturbance to the stream bed with this Erosion and Sediment Control Plan. The current conditions of this lot consist of
approximately 30.57 acres of vacant land that crosses Buck Mountain and Muddy Creeks. Approximately 17.60 acres of the
property is in the 100-year flood plain. Total disturbed area is 1.60 acres. The driveway will cross both creeks as shown on the
E&SC Plan and the approved Flood Development Permit provided. The rural lot is bound by adjacent rural properties on the
north and east. The property is bound to the south by Shiffletts Mill Road. Critical areas include the floodplain area and
stream banks.
SEQUENCE OF MAJOR ACTIVITIES
1. Prior to any land disturbance, contractor is to have surveyor flag clearing limits. No clearing or grading is allowed
outside of limits. Permanent seeding shall be applied to areas where final grade is reached.
2. Install construction entrance to gain access to the site. Install silt fence, as indicated on the plans, ensure that silt fence
is placed 1 foot on the downhill side of all sill and or abutments so there is a s little earth moving activities along the
stream bank as possible. No stream disturbances shall occur with this Erosion and Sediment Control Plan.
3. Place bridges on concrete sill or abutments
4. Build the stonnwater conveyance channel as shown on sheet 3 of the plans.
5. Upon final stabilization and with the approval of the E&SC inspector exterior measures may be removed.
NOTE: It shall be the contractor or owners' responsibility to adhere to requests from the County's E&SC inspector to add or
modify E&S measures during construction.

Section 4. Erosion and Sediment Control Plan.
(Provide a reduced, 11x17 copy of the latest Erosion and Sediment Control Plan. Do not reference only.)
Approved erosion and sediment control plans for Nystrom Driveway are incorporated by reference as part of this Stormwater
Pollution Prevention Plan. Approved plans are included in this SWPPP binder.
Minimum Standards
1. Permanent or temporary soil stabilization shall be applied to 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 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.
2. During construction of the project, soil stock piles and borrow areas shall be stabilized or protected with sediment
trapping measures. The applicant is responsible for the temporary protection and permanent stabilization of all soil
stockpiles on site as well as borrow areas and soil intentionally transported from the project site.
3. A permanent vegetative cover shall be established on denuded areas not otherwise permanently stabilized. Permanent
vegetation shall not be considered established until a ground cover is achieved that is uniform, mature enough to
survive and will inhibit erosion.
4. Sediment basins and traps, perimeter dikes, sediment barriers and other measures intended to trap sediment shall be
constructed as a first step in any land -disturbing activity and shall be made functional before upslope land disturbance
takes place.
5. Stabilization measures shall be applied to earthen structures such as dams, dikes and diversions immediately after
installation.
6. Sediment traps and sediment basins 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.
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 25-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. Cut and fill slopes shall be designed and constructed in a manner that will minimize erosion. Slopes that are found to
be eroding excessively within one year of permanent stabilization shall be provided with additional slope stabilizing
measures until the problem is corrected.
8. Concentrated runoff shall not flow down cut or fill slopes unless contained within an adequate temporary or
permanent channel, flume or slope drain structure.
9. Whenever water seeps from a slope face, adequate drainage or other protection shall be provided.
10. All storm sewer inlets that are made operable 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.
11. Before newly constructed stormwater 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.
12. When work in a live watercourse is performed, precautions shall be taken to minimize encroachment, control
sediment transport and stabilize the work area to the greatest extent possible during construction. Non -erodible
material shall be used for the construction of causeways and cofferdams. Earthen fill may be used for these structures
if armored by non -erodible cover materials.
13. When a live watercourse must be crossed by construction vehicles more than twice in any six-month period, a
temporary vehicular stream crossing constructed of non -erodible material shall be provided.
14. All applicable federal, state and local requirements pertaining to working in or crossing live watercourses shall be
met.
15. The bed and banks of a watercourse shall be stabilized immediately after work in the watercourse is completed.
16. Underground utility lines shall be installed in accordance with the following standards in addition to other applicable
criteria:
Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County
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 backfilling trenches shall be properly compacted in order to minimize erosion and promote
stabilization.
e. Re -stabilization shall be accomplished in accordance with this chapter.
f. Applicable safety requirements shall be complied with.
17. lwhere construction vehicle access routes intersect paved or public roads, provisions shall be made to minimize the
transport of sediment by vehicular tracking onto the paved surface. Where sediment is transported onto a paved or
public road surface, the road surface shall be cleaned thoroughly 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. This provision shall apply to individual development lots as
well as to larger land -disturbing activities.
18. 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 vescp authority. Trapped
sediment and the disturbed soil areas resulting from the disposition of temporary measures shall be permanently
stabilized to prevent further erosion and sedimentation.
19. Properties and waterways downstream from development sites shall be protected from sediment deposition, erosion
and damage due to increases in volume, velocity and peak flow ra to of stormwater runoff for the stated frequency
storm of 24-hour duration in accordance with the following standards and criteria. Stream restoration and relocation
projects that incorporate natural channel design concepts are not man-made channels and shall be exempt from any
flow rate capacity and velocity requirements for natural or man-made channels:
a. Concentrated stormwater runoff leaving a development site shall be discharged directly into an adequate
natural or man-made receiving channel, pipe or storm sewer system. For those sites where runoff is
discharged into a pipe or pipe system, downstream stability analyses at the outfall of the pipe or pipe system
shall be performed.
b. Adequacy of all channels and pipes shall be verified in the following manner:
1. The applicant shall demonstrate that the total drainage area to the point of analysis within the
channel is 100 times greater than the contributing drainage area of the project in question; or
2. ...
a) Natural channels shall be analyzed by the use of a two-year storm to verify that stormwater
will not overtop channel banks nor cause erosion of channel bed or banks;
b) All previously constructed man-made channels shall be analyzed by the use of a 10-year
storm to verify that stormwater will not overtop its banks and by the use of a two-year storm
to demonstrate that stormwater will not cause erosion of channel bed or banks; and
c) Pipes and storm sewer systems shall be analyzed by the use of a 10-year storm to verify that
stormwater will be contained within the pipe or system.
c. If existing natural receiving channels or previously constructed man-made channels or pipes are not adequate,
the applicant shall:
1. Improve the channels to a condition where a 10-year storm will not overtop the banks and a two-
year storm will not cause erosion to the channel, the bed, or the banks;
2. Improve the pipe or pipe system to a condition where the 10-year storm is contained within the
appurtenances;
3. Develop a site design that will not cause the pre -development peak runoff rate from a two-year
storm to increase when runoff outfalls into a natural channel or will not cause the pre -development
peak runoff rate from a 10-year storm to increase when runoff outfalls into a man-made channel; or
4. Provide a combination of channel improvement, stormwater detention or other measures which is
satisfactory to the VESCP authority to prevent downstream erosion.
d. The applicant shall provide evidence of permission to make the improvements.
e. All hydrologic analyses shall be based on the existing watershed characteristics and the ultimate development
condition of the subject project.
f. If the applicant chooses an option that includes stormwater detention, he shall obtain approval from the vescp
of a plan for maintenance of the detention facilities. The plan shall set forth the maintenance requirements of
the facility and the person responsible for performing the maintenance.
g. Outfall from a detention facility shall be discharged to a receiving channel, and energy dissipators shall be
placed at the outfall of all detention facilities as necessary to provide a stabilized transition from the facility to
Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County
the receiving channel.
h. All on -site channels must be verified to be adequate.
i. Increased volumes of sheet flows that may cause erosion or sedimentation on adjacent property shall be
diverted to a stable outlet, adequate channel, pipe or pipe system, or to a detention facility.
j. In applying these stormwater management criteria, individual lots or parcels in a residential, commercial or
industrial development shall not be considered to be separate development projects. Instead, the development,
as a whole, shall be considered to be a single development project. Hydrologic parameters that reflect the
ultimate development condition shall be used in all engineering calculations.
k. All measures used to protect properties and waterways shall be employed in a manner which minimizes
impacts on the physical, chemical and biological integrity of rivers, streams and other waters of the state.
1. Any plan approved prior to July 1, 2014, that provides for stormwater management that addresses any flow
rate capacity and velocity requirements for natural or man-made channels shall satisfy the flow rate capacity
and velocity requirements for natural or man-made channels if the practices are designed to
1. Detain the water quality volume and to release it over 48 hours;
2. Detain and release over a 24-hour period the expected rainfall resulting from the one year, 24-hour
stone; and (ill) reduce the allowable peak flow rate resulting from the 1.5, 2, and 10-year, 24- hour
storms to a level that is less than or equal to the peak flow rate from the site assuming it was in a
good forested condition, achieved through multiplication of the forested peak flow rate by a
reduction factor that is equal to the runoff volume from the site when it was in a good forested
condition divided by the runoff volume from the site in its proposed condition, and shall be exempt
from any flow rate capacity and velocity requirements for natural or man-made channels as defined
in any regulations promulgated pursuant to § 62.1-44.15:54 or 62.1-44.15:65 of the act. M.
in. For plans approved on and after July 1, 2014, the flow rate capacity and velocity requirements of § 62.1-
44.15:52 A of the act and this subsection shall be satisfied by compliance with water quantity requirements in
the stormwater management act (§ 62.1- 44.15:24 et seq. Of the code of Virginia) and attendant regulations,
unless such land -disturbing activities (i) are in accordance with provisions for time limits on applicability of
approved design criteria in 9vac25-870-47 or grandfathering in 9vac25-870-48 of the Virginia stormwater
management program (VSMP) regulation, in which case the flow rate capacity and velocity requirements of
§62.1-44.15:52 A OF the act shall apply, OR (II) are exempt pursuant to §62.1-44.15:34 C 7 of the act.
n. Compliance with the water quantity minimum standards set out in 9vac25-870-66 of the Virginia stormwater
management program (VSMP) regulation shall be deemed to satisfy the requirements of this subdivision 19.

STREAM -BUFFER MITIGATION MAINTENANCE NOTES
1. VISUALLY INSPECT PLANTING AREAS ON AN ANNUAL BASIS.
A. RESEED BARE SPOTS WITH A MIXTURE OF GRASS, PERENNIAL AND/OR WOODY VEGETATION SEEDS. USE NATIVE
SPECIES ONLY.
B. IDENTIFY WEED PROBLEMS WITHIN THE PLANTING AREA.
a. CONTROL WEEDS AS SOON AS POSSIBLE BEFORE THEY GROW OUT OF CONTROL. WEED CONTROL METHODS WILL
VARY, BUT MAY INCLUDE REMOVAL BY HAND, MOWING, SELECTIVE USE OF HERBICIDES, MULCHING, AND OTHER
INTEGRATED VEGETATION MANAGEMENT (IVM) TECHNIQUES.
b. CONTINUE WEED CONTROL UNTIL WOODY PLANTS ARE FULLY ESTABLISHED IN THE PLANTING AREA, NORMALLY 2 TO
3 YEARS AFTER PLANTING.
C. INSPECT AREA FOR EVIDENCE OF HIGH DEER BROWSE PRESSURE OR RODENT POPULATIONS.
a. IF THERE IS EVIDENCE OF HIGH IMMORTALITY RATE, CONSIDER AVAILABLE OPTIONS FOR CONTROLLING PEST
PROBLEM SUCH AS FENCING TREE SHELTERS AND TREE CAGES TO REPELLENTS INCLUDING IN -SOIL SYSTEMIC
TABLETS FOLIAR SPRAYS OF MANY TYPES AND ACTIVE INGREDIENTS.
D. CHECK SURVIVAL IN LATE FALL AFTER SECOND YEAR TO ESTABLISH SURVIVAL RATE. MINIMAL SURVIVAL IS 490
PLANTS/ACRE OR A 70% SURVIVAL RATE FOR SEEDLINGS.
a. IF THE SURVIVAL RATE IS NOT AT THE SPECIFIED MINIMUM AND REPLACEMENT PLANTINGS ARE WARRANTED,
PLANTING AREAS SHOULD BE SURVEYED TO TRY TO IDENTIFY THE LIKELY CAUSE OF THE PLANT MORTALITY.
SOURCES OF THE MORTALITY SHOULD BE CONTROLLED AND MITIGATED FOR PRIOR PLANTINGS REPLACEMENTS.
E. CHECK FOR NATURAL REGENERATION. WHERE ABUNDANT, LIMIT FURTHER MOWING UNLESS SITE IS PRONE TO VOLES
OR INVASIVE PLANTS.
F. IF TREE TUBES ARE USED, REGULARLY INSPECT THEM TO MAKE SURE THEY ARE NOT TOO TIGHT ON THE TREE, THAT
SMALL ANIMALS OR INSECTS HAVE NOT BUILT NESTS INSIDE THE TUBES, AND THAT THE TREE IS GROWING PROPERLY.
REPLACE OR REMOVE THE TUBES AS NEEDED.
G. IN YEARS 3-5, PRUNE AND THIN TREES AND SHRUBS TO ENSURE ADEQUATE GROWING SPACE AND OPTIMAL GROWTH
RATES.
2. VISUALLY INSPECT PLANTING AREAS AFTER MAJOR STORM EVENTS.
A. IF STORM DAMAGE IS PRESENT, FIX EROSION DAMAGE THEN REPLANT AREA AT THE MINIMUM PLANTING RATE FROM
THE ORIGINAL PLANTING PLAN OR RESEED MANUFACTURES' RECOMMENDED APPLICATION RATE
3. IF POSSIBLE, AVOID WORKING IN THE RIPARIAN AREA BETWEEN APRIL 15 AND AUGUST 15. DURING THIS TIME PERIOD,
DISTURBANCE CAN BE DETRIMENTAL TO A VARIETY OF WILDLIFE, BECAUSE OF MATING AND NEWLY BORN WILDLIFE.

5) If possible, stop spill from entering drains (use absorbent or other material as necessary)
6) Stop spill from spreading (use absorbent or other materials necessary)
7) If spill material has entered a stone sewer or public waters; contact locality's storm sewer water department,
locality's VSMP inspector, local VDEQ Office and VA Department of emergency services.
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.
"Spill report form and procedure can be found in Section 13. Additional Information and Logs"
(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 stonnwater 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 Appendix J.
(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 stone 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
Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County
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 with the "Final Construction Plans".
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:
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
Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County
Drawing included with the "Final Construction Plans". An EPA concrete washout factsheet is provided in
Appendix I. 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 stonnwater 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

from construction activities.
This general permit also authorizes stormwater discharges from support activities (e.g.,
concrete or asphalt batch plants, equipment staging yards, material storage areas, excavated
material disposal areas, borrow areas) located on -site or off -site provided that:
a. The support activity is directly related to the construction activity that is required to have
general permit coverage for discharges of stormwater from construction activities;
b. The support activity is not a commercial operation, nor does it serve multiple unrelated
construction activities by different operators;
c. The support activity does not operate beyond the completion of the last construction
activity it supports;
d. The support activity is identified in the registration statement at the time of general permit
coverage;
e. Appropriate control measures are identified in a stormwater pollution prevention plan and
implemented to address the discharges from the support activity areas; and
f. All applicable state, federal, and local approvals are obtained for the support activity.
B. Limitations on coverage.
1. Post -construction discharges. This general permit does not authorize stormwater discharges
that originate from the site after construction activities have been completed and the site,
including any support activity sites covered under the general permit registration, has
undergone final stabilization. Post -construction industrial stormwater discharges may need to
be covered by a separate VPDES permit.

other plans such as a spill prevention control and countermeasure (SPCC) plan developed for
the site under § 311 of the federal Clean Water Act or best management practices (BMP)
programs otherwise required for the facility provided that the incorporated plan meets or
exceeds the SWPPP requirements of Part II B. All plans incorporated by reference into the
SWPPP become enforceable under this general permit. If a plan incorporated by reference
does not contain all of the required elements of the SWPPP, the operator shall develop the
missing elements and include them in the SWPPP.
3. Any operator that was authorized to discharge under the general permit effective July 1, 2014,
and that intends to continue coverage under this general permit, shall update its stormwater
pollution prevention plan to comply with the requirements of this general permit no later than
60 days after the date of coverage under this general permit.
B. Contents. The SWPPP shall include the following items:
1. General information.
a. A signed copy of the registration statement, if required, for coverage under the general
VPDES permit for discharges of stormwater from construction activities;

standards and specifications, implemented to:
(1) Control the volume and velocity of stormwater runoff within the site to minimize soil
erosion;
(2) Control stormwater discharges, including peak flow rates and total stormwater volume,
to minimize erosion at outlets and to minimize downstream channel and stream bank
erosion;
Page 8 of 26
(3) Minimize the amount of soil exposed during the construction activity;
(4) Minimize the disturbance of steep slopes;
(5) Minimize sediment discharges from the site in a manner that addresses (i) the amount,
frequency, intensity, and duration of precipitation; (ii) the nature of resulting stormwater
runoff; and (iii) soil characteristics, including the range of soil particle sizes present on
the site;
(6) Provide and maintain natural buffers around surface waters, direct stormwater to
vegetated areas to increase sediment removal, and maximize stormwater infiltration,
unless infeasible;
(7) Minimize soil compaction and, unless infeasible, preserve topsoil;
(8) Ensure initiation of stabilization activities, as defined in 9VAC25-880-1, of disturbed
areas immediately whenever any clearing, grading, excavating, or other land -
disturbing activities have permanently ceased on any portion of the site, or temporarily
ceased on any portion of the site and will not resume for a period exceeding 14 days;
and
(9) Utilize outlet structures that withdraw stormwater from the surface (i.e., above the
permanent pool or wet storage water surface elevation), unless infeasible, when
discharging from sediment basins or sediment traps.
3. Stormwater management plan.

a stormwater management plan prepared in accordance with annual standards and
specifications approved by the department.
b. For any operator meeting the conditions of 9VAC25-870-47 B of the VSMP regulation, an
approved stormwater management plan is not required. In lieu of an approved stormwater
management plan, the SWPPP shall include a description of, and all necessary
calculations supporting, all post -construction stormwater management measures that will
be installed prior to the completion of the construction process to control pollutants in
stormwater discharges after construction operations have been completed. Structural
measures should be placed on upland soils to the degree possible. Such measures must
be designed and installed in accordance with applicable VESCP authority, VSMP
authority, state, and federal requirements, and any necessary permits must be obtained.
Pollution prevention plan. A pollution prevention plan that addresses potential pollutant -
generating activities that may reasonably be expected to affect the quality of stormwater
discharges from the construction activity, including any support activity. The pollution
prevention plan shall:
a. Identify the potential pollutant -generating activities and the pollutant that is expected to be
exposed to stormwater;
Page 9 of 26
b. Describe the location where the potential pollutant -generating activities will occur, or if
identified on the site plan, reference the site plan;
c. Identify all nonstormwater discharges, as authorized in Part I E of this general permit, that
are or will be commingled with stormwater discharges from the construction activity,
including any applicable support activity;
d. Identify the person responsible for implementing the pollution prevention practice or
practices for each pollutant -generating activity (if other than the person listed as the
qualified personnel);
e. Describe the pollution prevention practices and procedures that will be implemented to:

and (ii) procedures for reporting leaks, spills, and other releases in accordance with
Part III G;
(2) Prevent the discharge of spilled and leaked fuels and chemicals from vehicle fueling
and maintenance activities (e.g., providing secondary containment such as spill
berms, decks, spill containment pallets, providing cover where appropriate, and having
spill kits readily available);
(3) Prevent the discharge of soaps, solvents, detergents, and wash water from
construction materials, including the clean-up of stucco, paint, form release oils, and
curing compounds (e.g., providing (i) cover (e.g., plastic sheeting or temporary roofs)
to prevent contact with stormwater; (ii) collection and proper disposal in a manner to
prevent contact with stormwater; and (iii) a similarly effective means designed to
prevent discharge of these pollutants);
(4) Minimize the discharge of pollutants from vehicle and equipment washing, wheel wash
water, and other types of washing (e.g., locating activities away from surface waters
and stormwater inlets or conveyance and directing wash waters to sediment basins or
traps, using filtration devices such as filter bags or sand filters, or using similarly
effective controls);
(5) Direct concrete wash water into a leak -proof container or leak -proof settling basin. The
container or basin shall be designed so that no overflows can occur due to inadequate
sizing or precipitation. Hardened concrete wastes shall be removed and disposed of
in a manner consistent with the handling of other construction wastes. Liquid concrete
wastes shall be removed and disposed of in a manner consistent with the handling of

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.

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
Figure 4. Vacuuming washwater out of a
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.
Figure 5. Ready mixed truck washing
out into a reclaimer
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
bale and plastic
Figure 10. Leaking
washoutpitthat
has not been well
maintained
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

Delivering
hardened Concrete
to a recycler
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
the construction
site to wash
out other mixer
truck chutes
and equipment. Figure 16. Washout container with a rain coverand

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.
