been damaged by erosion or construction equipment. The height of the stone outlet should
be checked to ensure that its center is at least V below the top of the embankment.
3.17 - Stormwater Conveyance Channel
Grass -lined Channels
During the initial establishment, grass -lined channels should be repaired immediately and grass
re-established if necessary. After grass has become established, the channel should be checked
periodically to determine if the grass is withstanding Flow velocities without damage. If the channel
is to be mowed, it should be done in a manner that will not damage the grass.
3.18 - Outlet Protection
a. Inspect after each significant min for erosion and/or disruption of the rock,
and repair immediately.
b. Grouted or wire -tied rock ripmp can minimize maintenance requirements.
3.32 - Permanent Seeding
In general, a stand of vegetation cannot be determined to be fully established until it has been
maintained for one full year after planting.
Irrigation: New seedings should be supplied with adequate moisture. Supply water as needed,
especially late in the season, In abnormally hot or dry weather, or on adverse sites. Water
application rates should be controlled to prevent excessive runoff. Inadequate amounts of water
may be more harmful than no water.
Re -seeding: Inspect seeded areas for failure and make necessary repairs and re-seedings within
the same season, if possible.
a. If vegetative cover is inadequate to prevent rill erosion, over -seed and fertilize in accordance
with ..it test results.
b. If a stand has less than 40% cover, re-evaluate choice of plant materials and quantities of
lime and fertilizer. The soil must be tested to determine if acidity or nutrient imbalances are
responsible. Re-establish the stand following seedbed preparation and seeding
recommendations.
Fertilization: Cool season grasses should begin to be fertilized 90 days after planting to ensure
proper stand and density. Warm season fertilization should begin at 30 days after planting. Apply
maintenance levels of fertilizer as determined by soil test. In the absence of a ..it test, fertilization
should be as follows:
Cool Season Grasses: 4lips. Nitrogen (N), 1 lb. Phosphorus (P), 21bs. Potash (K) per 1000 ft.' per
year
75 % of the total requirements should be applied between Sept. 1 and Dec. 31 at. The balance
should be applied during the remainder of the year. More than 1 lb. of soluble nitrogen per 1000 ft.'
should not be applied at any one time.
3.33 - Sodding
a. During the 2 to 3 week establishment stage, sod shall be watered as necessary to maintain
adequate moisture in the root zone and prevent dormancy of sod.
b. No more than one third of the shoot (grass leaf) should be removed in any mowing. Grass
height should be maintained between 2 and 3 inches unless otherwise specified.
c. After the first growing season, established sod will require fertilization and may require lime.
Follow soil test recommendations when possible, or apply maintenance levels as outlined in
Table 3.33-B.
3.35 - Mulching
All mulches and soil coverings should be inspected periodically (particularly after rainstorms) to
check for erosion. Where erosion is observed in mulched areas, additional mulch should be
applied. Nets and mats should be inspected after rainstorms for dislocation or failure. If washouts
or breakage occur, re -install netting or matting as necessary after repairing damage to the slope or
ditch. Inspections should take place up until grasses are firmly established. Where mulch is used in
conjunction with ornamental plantings, inspect periodically throughout the year to determine if mulch
is maintaining coverage of the soil surface; repair as needed. Application rate = 2 tons per acre. All
mulching shall be anchored in place.
3.36 - Soil Stabilization Blankets and Matting
All soil stabilization blankets and matting should be inspected periodically following installation,
particularly after rainstorms to check for erosion and undermining. Any dislocation or failure should
be repaired immediately. If washouts or breakage occurs, re -install the material after repairing
damage to the slope or ditch. Continue to monitor these areas until which time they become
permanently stabilized; at that time an annual inspection should be adequate.
11. MANAGEMENT STRATEGIES
A. Construction will be sequenced so that grading operations can begin and end as quickly as
possible.
B. Sediment trapping measures will be installed as a first step in grading and will be seeded and
mulched immediately following installation.
C. Temporary seeding or other stabilization will follow immediately after grading. Stabilization for all
critical areas will consist of EC-2 lining.

E. The job superintendent shall be responsible for the installation and maintenance of all erosion and
1 P Po
sediment control practices.
F. After achieving adequate stabilization, the temporary erosion controls will be cleaned up and
removed.

1. Inspect bi-annually and after each storm event the contributing drainage areas, Bioretention Facility,
inlets, outlets, underdmins, overflows and clemouts for debris, sediment, proper drainage and damages.
Clean and dispose of all debris, trash and sediment properly. Should structural damages be encountered
contact design engineer for replacement information and notify the County of Augusta Engineer of the
damages and proposed repair procedures.
2. The observation well shall be checked quarterly and after each large storm event. A log book shall be
maintained
showing the depth ofwater in the well during each inspection in order to determine the rate
at which the facility dewaters after runoff producing storm events. Once the performance characteristics
of the structure have been verified, the monitoring schedule can be reduced to an annual basis, unless
the performance data suggests that a more frequent schedule is required. At the end of the that year the
Landowner shall provide a copy of the log book and the revised monitoring schedule to the county
engineering department to be reviewed by the Erosion and Sediment control inspector. The inspector
will approve the revised monitoring schedule or require further inspections that shall be carried out by
the Landowner.
3. Inspect plant material bi-annually. Address any problems found due to disease or insect infestations.
Diseased plants most be treated by a qualified professional. Replace any dead plant material and prime
esary. Consult a landscape architect or horticulturist for specific pruning measures. All
replacement plants shall meet original design specifications. New plants shall be watered everyday for
the first 14 days after planting.
4. Conduct organic layer and soil tests twice a year to maintain proper pH. An application of alkaline,
such as limestone, shall be applied as needed per test results.
5. The soil mix shall be tested annually to check for the presence of toxins and heavy metals. If levels are
high and the plant biologic functions are impaired (dwarfed growth and mortality) the contaminated
soil and any deadnt plas shall be removed and replaced. All removed material shall be disposed of
properly. In some cases, the removal and disposal of the entire soil base as well as the plant material
may be required. Replacement soil mix and plants shall meet original design specifications.
6. Inspect mulch layer for voids and to ensure specified thickness. Replacement ofmulch layer is required
every two to three years. Mulch shall be replaced in spring. The previous layer shall be removed first.
7. When sand or other street abrasives are used on areas draining to bioretention basin during snow and
icing conditions the pavement shall be power/vacuum swept as soon as freezing weather abates to
prevent damage to the basins.
8. Inspect bi-annually all inlets structures, manholes, storm pipes, clemouts and roof drains for proper
drainage and structural integrity. Should damages be encountered contact design engineer for
replacement information and notify County Engineering department of damages and repair procedures.
9. Inspect bi-annually all inlets structures, manholes, storm pipes, cleanouts and roof drains for debris and
sediment. Clean and dispose of all debris, trash and sediment properly.

1 sr Priority: Protect all people
2"a Priority: Protect equipment and property
3`d Priority: Protect the environment
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. LARGE SPILLS ARE LIKELY TO PRESENT A HAZARD.
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 spilled material has entered a storm sewer; contact locality's storm water department.
8. Clean up spilled material according to manufacturer specifications, for liquid spills use absorbent materials and do not flush area
with water.
9. Properly dispose of cleaning materials and used absorbent material according to manufacturer specifications.

G. Pollution Prevention Awareness
(Describe training and procedures to provide awareness and compliance for all measures in this
document; waste management, wash waters, prevention measures, etc.)
1) Controls and Measures
The Permit requires the implementation of various types of controls and measures that are implemented
to control pollutants in storm water discharges from the project site. The Permit specifically requires
the implementation of erosion and sediment control practices (both structural and non-structural), storm
water management practices, and specific other controls to reduce pollutants. All E & S and
SWM/BMP controls employed in this project were selected to meet and/or exceed State and local
requirements and are detailed in the referenced design plans.
Several requirements of the Permit relating to controls (Part II. , Appendix A) are not included in the
referenced design plans. A description of all the required items (including E&S and SWM/BMP) is
presented below, along with how they are addressed in this Plan:
a) Erosion and Sediment Control
The design plans for this project, Crozet Business Office, contain detailed information regarding
erosion and sediment controls used in this project. Specifically E & S control measures can be
found on sheets C5, C6, & C7.
Stabilization measures shall be initiated as soon as practicable in portions of the site where
construction activities have temporarily or permanently ceased, but in no case more than seven days
after the construction activity in that portion of the site has temporarily or permanently ceased.
Where construction activity on a portion of the site is temporarily ceased, and earth disturbing
activities will be resumed within 14 days, temporary stabilization measures do not have to be
initiated on that portion of the site.
In drought -stricken areas where initiating perennial vegetative stabilization measures is not
possible within seven days after construction activity has temporarily or permanently ceased, final
vegetative stabilization measures shall be initiated as soon as practicable.
All control measures must be properly selected, installed and maintained in accordance with
manufacturer specifications and good engineering practices. If periodic inspections or other
information indicates a control has been used inappropriately, or incorrectly, the permittee must
replace or modify the control for site situations as soon as practicable.
If sediment escapes the construction site, off -site accumulations of sediment must be removed at
a frequency sufficient to minimize off -site impacts.
Litter, construction debris, and construction chemicals exposed to storm water shall be prevented
from becoming a pollutant source in storm water discharges. Such items will be elevated away
from runoff and covered or tarped whenever practicable to reduce exposure to stormwater.
No solid materials, including building materials, garbage, and debris shall be discharged to surface
waters of the state, except as authorized a Clean Water Permit Section 404 permit.
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.
b) SWM/BMP's
The design plans for this project, Crozet Business Office, contains detailed information regarding
SWM/BMP controls used in this project. Specifically Stormwater Management Control Measures
can be found on sheets C3, C4, & C8.
c) Fuels and Oils
(i) On -site vehicle refueling will be conducted in a dedicated location away from access to surface
waters. Since the location of fueling activities will periodically move during construction, the
design plans do not contain a specific location. For each phase of work a location will be
determined in the field and noted in the Site Inspection Log (Appendix D). Containment berms
will be located adjacent to the refueling area that will contain any inadvertent spills until they
can be cleaned up. Any on -site storage tanks will have a means of secondary containment. In
the event of a spill, it will be cleaned up immediately and the material, including any
contaminated soil, will be disposed of according to all federal, state, and local regulations.
(ii) All vehicles on site will be monitored for leaks and receive regular preventive maintenance to
reduce the chance of leakage.
(iii) Petroleum products will be stored in tightly sealed containers which are clearly labeled.
(iv) Spill kits will be stored and readily available at all fueling sources and maintenance activities.
(v) Any asphalt substances used onsite will be applied according to the manufacturer's
recommendation.
d) Solid Waste
No solid materials shall be discharged to surface water. Solid materials, including building
materials, garbage, and debris shall be cleaned up daily and deposited into dumpsters, which will
be periodically removed from the site and deposited into a landfill.
e) Fertilizer
(i) Fertilizers will be applied only in the minimum amounts recommenced by the manufacturer.
(ii) Fertilizers will be worked into the soil to limit exposure to storm water.
(iii) Fertilizers will be stored in a covered shed and partially used bags will be transferred to a
sealable bin to avoid spills.
f) Paint and other Chemicals
(i) All paint containers and curing compounds will be tightly sealed and stored when not required
for use. Excess paint will not be discharged to the storm sewers, but will be properly disposed
according to the manufacturer's instructions.
(ii) Spray guns will be cleaned on a removable tarp.
(iii) Chemicals used on -site are kept in small quantities and stored in closed containers undercover
and kept out of direct contact with storm water. As with fuels and oils, any inadvertent spills
will be cleaned up immediately and disposed of according to federal, state, and local
regulations.
g) Concrete
(i) Concrete trucks will not be allowed to wash out or discharge surplus concrete or drum wash
water on the site, except into leak -proof containers or leak -proof settling basins which are
located in the designated concrete disposal area.
(ii) Form release oil used for decorative stone work will be applied over a pallet covered with an
absorbent material to collect excess fluid. The absorbent material will be replaced and
disposed of properly when saturated.
h) Water Testing
When testing/cleaning of water supply lines, the discharge from the tested pipe will be collected
and conveyed to a completed storm water pipe system for ultimate discharge into a sedimentation
basin or SWMBMP facility.
i) Sanitary Waste
Portable lavatories are located on -site and are serviced on a regular basis by a contractor. They will
be located in upland 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.
j) Grading and E & S Activities
A record of the dates when major grading activities occur, when construction activities temporarily
or permanently cease on a portion of the site, and when stabilization measures are initiated shall be
maintained and included in Appendix C of this plan or in another acceptable location onsite.
2) Spills
Oil, chemical or other hazardous substance spills in excess of reportable quantities, in accordance with
Part I E. of the Permit (Appendix A), will be reported to the Department in accordance with Part III G.
of the Permit as soon as the discharge is discovered, but no later than 24 hours. A reportable quantity
of oil is defined as a discharge to a surface water that causes a sheen, discoloration, and/or an emulsion.
Reports will be made to the following:
DEQ Valley Regional Office
Phone: (540) 574-7800
Fax: (540) 574-7878
For reports outside normal working hours, leave a message.
Virginia Department of Emergency Management
Emergency Operations Center (EOC)
Phone: 1-(800) 468-8892
Materials and equipment necessary for oil or chemical spill cleanup will be kept in the temporary
material storage trailer onsite. Equipment will include, but not be limited to, brooms, dust pans, mops,
rags, gloves, goggles, kitty litter, sand, saw dust, and plastic and metal trash containers.
All oil or other chemical spills will be cleaned up immediately upon discovery. Spills large enough to
reach the storm sewers will be reported to the National Response Center at 1-800-424-8802. If serious
hazards to personal health are present, leave area and call 911.
3) Maintenance
Maintenance of the erosion and sediment controls and the storm water management/BMP facilities
incorporated into this project must be maintained on a regular basis to assure their continued
effectiveness. This includes repairs to all erosion and sediment controls, including cleanout of all
sediment basins and storm water management facilities at the required intervals. Those controls found
to be ineffective during routine inspections (as described in the following section) shall be repaired
before the next anticipated storm event or as soon as practicable. A more detailed description of the
maintenance procedures is contained in the design plans, Town & Country, on sheet C5, and is
incorporated in this plan by reference.
4) Inspections
Inspections by qualified personnel shall be conducted of all areas of the site disturbed by construction
activity, and areas used for storage of materials that are exposed to storm water. "Qualified personnel"
means a licensed professional engineer, responsible land disturber (RLD), or other knowledgeable
person who (i) holds a certificate of competence from the board in the area of project inspection; or (ii)
is enrolled in the board's training program for project inspection or combined administrator and
successfully completes such program within one year of enrollment.
Inspections shall include the review of all disturbed areas, structural and non-structural control
measures, material storage areas, and vehicular access points. Inspections are to be performed at least
once every 10 business days and within 48 hours after a measureable storm event. A rain gauge shall
be installed on -site in an open and accessible area to measure such storm events. Areas that already
have been stabilized or where runoff is unlikely due to frozen or snow covered ground shall be inspected
at least on a monthly basis.
Inspections are intended to identify areas where the pollutant control measures at the site are ineffective
and are allowing pollutants to enter surface waters. Receiving waters shall be inspected to ascertain
whether control measures are effective in preventing significant impacts. Locations where vehicles
enter or exit the site shall be inspected for evidence of offsite sediment tracking.
If as a result of the inspection, the site conditions and/or control measures are found to have changed,
the plan shall be updated within a period of 7 calendar days. If control measures need to be modified
to assure effectiveness or if additional measures are determined to be necessary, implementation shall
be completed prior to the next anticipated storm event or as soon as practicable.
A report summarizing the inspections and the subsequent maintenance activities must be completed
and maintained as part of the plan. The sample inspection forms are included in Appendix D.
Required inspection elements include but are not limited to:
1. Recording the date and time of the inspection and when applicable the date and rainfall amount of
the last measurable storm event;
2. Recording the information and a description of any discharges occurring at the time of the
inspection;
3. Recording any land -disturbing activities that have occurred outside of the approved erosion and
sediment control plan;
4. Inspecting the following for installation in accordance with the approved erosion and sediment
control plan, identification of any maintenance needs, and evaluation of effectiveness in
minimizing sediment discharge, including whether the control has been inappropriately or
incorrectly used:
a. All perimeter erosion and sediment controls, such as silt fence;
b. Soil stockpiles, when applicable, and borrow areas for stabilization or sediment trapping
measures;
c. Completed earthen structures, such as dams, dikes, ditches, and diversions for stabilization;
General Permit No.: VAR10 Page 12 of 21
d. Cut and fill slopes;
e. Sediment basins and traps, sediment barriers, and other measures installed to control sediment
discharge from stormwater;
f. Temporary or permanent channel, flume, or other slope drain structures installed to convey
concentrated runoff down cut and fill slopes;
g. Storm inlets that have been made operational to ensure that sediment laden stormwater does
not enter without first being filtered or similarly treated; and
h. Construction vehicle access routes that intersect or access paved roads for minimizing
sediment tracking;
5. Inspecting areas that have reached final grade or that will remain dormant for more than 14 days
for initiation of stabilization activities;
6. Inspecting areas that have reached final grade or that will remain dormant for more than 14 days
for completion of stabilization activities within seven days of reaching grade or stopping work;
7. Inspecting for evidence that the approved erosion and sediment control plan, "agreement in lieu of
a plan," or erosion and sediment control plan prepared in accordance with department -approved
annual standards and specifications has not been properly implemented. This includes but is not
limited to:
a. Concentrated flows of stormwater in conveyances such as rills, rivulets or channels that have
not been filtered, settled, or similarly treated prior to discharge, or evidence thereof;
b. Sediment laden or turbid flows of stormwater that have not been filtered or settled to remove
sediments prior to discharge;
c. Sediment deposition in areas that drain to unprotected stormwater inlets or catch basins that
discharge to surface waters. Inlets and catch basins with failing sediments controls due to
improper installation, lack of maintenance, or inadequate design are considered unprotected;
d. Sediment deposition on any property (including public and private streets) outside of the
construction activity covered by this general permit;
e. Required stabilization has not been initiated or completed on portions of the site;
f. Sediment basins without adequate wet or dry storage volume or sediment basins that allow the
discharge of stormwater from below the surface of the wet storage portion of the basin;
g. Sediment traps without adequate wet or dry storage or sediment traps that allow the discharge
of stormwater from below the surface of the wet storage portion of the trap; and
h. Land disturbance outside of the approved area to be disturbed;
8. Inspecting areas that have reached final grade or that will remain dormant for more than 14 days
for initiation of stabilization activities;
9. Identify any pollutant generating activities not identified in the pollution prevention plan; and
10. Identify and document the presence of any evidence of the discharge of pollutants prohibited by
this general permit.
Required documentation elements include but are not limited to:
1. Summarized findings of the inspection;
2. The location(s) of prohibited discharges;
3. The locations(s) of control measures that require maintenance;
4. The locations(s) of control measures that have failed to operate as designed or proved inadequate
or inappropriate for a particular location;
5. The locations(s) where any evidence identified under section 7 above exists;
6. The locations(s) where any additional control measure is needed that did not exist at the time of
inspection;
7. A list of corrective actions required (including any changes to the SWPPP that are necessary) as a
result of the inspection or to maintain permit compliance;
8. Documentation of any corrective actions required from a previous inspection that have not been
implemented; and
9. The date and signature of the qualified personnel and the operator or its duly authorized
representative.
The operator shall implement the corrective action(s) identified as a result of an inspection as soon as
practicable but no later than seven (7) days after discovery or a longer period as approved by the VSMP
authority. If approval of a corrective action by a regulatory authority is necessary, additional control
measures shall be implemented to minimize pollutants in storm water discharges until such approvals
can be obtained. The operator needing to remove sediment from surface waters or wetlands shall obtain
approval to do so from applicable federal, state, and local authorities.
If an inspection does not identify any incidents of non-compliance, then the certification statement
contained in the inspection form will apply.
Utility line installation, pipeline construction, and other examples of long, narrow, linear construction
activities may limit the access of inspection personnel to the areas described in Section D 4 b.
Inspection of these areas could require that vehicles compromise temporarily or even permanently
stabilized areas, cause additional disturbance of soils, and increase the potential for erosion. In these
circumstances, controls must be inspected on the same frequencies as other construction projects, but
representative inspections may be performed. For representative inspections, personnel must inspect
controls along the construction site for 0.25 miles above and below each access point where a roadway,
undisturbed right-of-way, or other similar feature intersects the construction site and allows access to
the areas described above. The conditions of the controls, along each inspected 0.25-mile segment may
be considered as representative of the condition of controls along that reach extending from the end of
the 0.25-mile segment to either the end of the next 0.25-mile segment, or to the end of the project,
whichever comes first. Inspection locations must be listed in the report required by Section II D 4d.
5) Non -Storm Water Discharges
With the exception of flows from fire fighting activities, allowable sources of non -storm water
discharges (Part I D.2. of the Permit, Appendix A) must be identified in the plan. Appropriate measures
must be taken to ensure that pollution prevention measures for the non -storm water component of the
discharge are implemented. The non -storm water discharges associated with this project identified at
this time are:
a) Testing of Water as discussed under II, B, 2, h.
Other permitted discharges include:
a) Discharges from fire fighting activities;
b) Fire hydrant flushings;
c) Waters used to wash vehicles where detergents are not used;
d) Potable water sources, including waterline flushings;
e) Water used to control dust;
f) Water used for hydrostatic testing of new pipeline construction;
g) Routine external building wash down which does not use detergents;
h) Pavement washwaters where spills or leaks of toxic or hazardous materials have not occurred
(unless all spilled material has been removed) and where detergents are not used;
i) Uncontaminated air conditioning or compressor condensate;
j) Uncontaminated ground water or spring water;
k) Foundation or footing drains where flows are not contaminated with process materials such as
solvents;
1) Uncontaminated excavation dewatering, and
m) Landscape irrigation.

CHAPTER 880
GENERAL VPDES PERMIT FOR DISCHARGES OF STORMWATER FROM CONSTRUCTION
ACTIVITIES
9VAC25-880-1. Definitions.
The words and terms used in this chapter shall have the meanings defined in the Virginia
Stormwater Management Act (Article 2.3 (§ 62.1-44.15:24 et seq.) of Chapter 3.1 of Title 62.1 of
the Code of Virginia), this chapter, and 9VAC25-870 unless the context clearly indicates
otherwise, except as otherwise specified in this section. Terms not defined in the Act, this
chapter, or 9VAC25-870 shall have the meaning attributed to them in the federal Clean Water
Act (33 USC § 1251 et seq.) (CWA). For the purposes of this chapter:
"Business day" means Monday through Friday excluding state holidays.
"Commencement of land disturbance" means the initial disturbance of soils associated with
clearing, grading, or excavating activities or other construction activities (e.g., stockpiling of fill
material).
"Construction site" means the land where any land -disturbing activity is physically located or
conducted, including any adjacent land used or preserved in connection with the land -disturbing
activity.
"Final stabilization" means that one of the following situations has occurred:
1. All soil disturbing activities at the site have been completed and a permanent
vegetative cover has been established on denuded areas not otherwise permanently
stabilized. Permanent vegetation shall not be considered established until a ground
cover is achieved that is uniform (e.g., evenly distributed), mature enough to survive,
and will inhibit erosion.
2. For individual lots in residential construction, final stabilization can occur by either:
a. The homebuilder completing final stabilization as specified in subdivision 1 of this
definition; or
b. The homebuilder establishing temporary soil stabilization, including perimeter
controls for an individual lot prior to occupation of the home by the homeowner, and
informing the homeowner of the need for, and benefits of, final stabilization.
3. For construction projects on land used for agricultural purposes , final stabilization
may be accomplished by returning the disturbed land to its preconstruction agricultural
use. Areas disturbed that were not previously used for agricultural activities, such as
buffer strips immediately adjacent to surface waters, and areas that are not being
returned to their preconstruction agricultural use must meet the final stabilization criteria
specified in subdivision 1 or 2 of this definition.
"Immediately" means as soon as practicable, but no later than the end of the next business
day, following the day when the land -disturbing activities have temporarily or permanently
ceased. In the context of this general permit, "immediately" is used to define the deadline for
initiating stabilization measures.
"Impaired waters" means surface waters identified as impaired on the 2012 § 305(b)/303(d)
Water Quality Assessment Integrated Report.
"Infeasible" means not technologically possible or not economically practicable and
achievable in light of best industry practices.
"Initiation of stabilization activities" means:
1. Prepping the soil for vegetative or nonvegetative stabilization;
Pagel of 29
9VAC25-880 (adopted 12/17/2013 - published 2/24/2014 - effective 7/1/2014)
2. Applying mulch or other nonvegetative product to the exposed area;
3. Seeding or planting the exposed area;
4. Starting any of the above activities on a portion of the area to be stabilized, but not on
the entire area; or
5. Finalizing arrangements to have the stabilization product fully installed in compliance
with the applicable deadline for completing stabilization.
This list is not exhaustive.
"Measurable storm event" means a rainfall event producing 0.25 inches of rain or greater
over 24 hours.
"Stabilized" means land that has been treated to withstand normal exposure to natural
forces without incurring erosion damage.
9VAC25-880-10. Purpose.
This general permit regulation governs stormwater discharges from regulated construction
activities. For the purposes of this chapter, these discharges are defined as stormwater
discharges associated with large construction activity, and stormwater discharges associated
with small construction activity. Stormwater discharges associated with other types of industrial
activity shall not have coverage under this general permit. This general permit covers only
discharges through a point source to surface waters or through a municipal or nonmunicipal
separate storm sewer system to surface waters. Stormwater discharges associated with
industrial activity that originate from construction activities that have been completed and the
site has undergone final stabilization are not authorized by this general permit.
9VAC25-880-15. Applicability of incorporated references based on the dates that they
became effective.
Except as noted, when a regulation of the United States set forth in the Code of Federal
Regulations is referenced and incorporated herein, that regulation shall be as it exists and has
been published in the July 1, 2013, update.
9VAC25-880-20. Effective date of general permit.
This general permit is effective on July 1, 2014. The general permit will expire on June 30,
2019. This general permit is effective for any covered operator upon compliance with all
provisions of 9VAC25-880-30.
9VAC25-880-30. Authorization to discharge.
A. Any operator governed by this general permit is authorized to discharge to surface waters
of the Commonwealth of Virginia provided that:
1. The operator submits a complete and accurate registration statement, if required to do
so, in accordance with 9VAC25-880-50 and receives acceptance of the registration by
the board;
2. The operator submits any permit fees, if required to do so, in accordance with
9VAC25-870-700 et seq.;
3. The operator complies with the applicable requirements of 9VAC25-880-70;
4. The operator obtains approval of:
Page 2 of 29
9VAC25-880 (adopted 12/17/2013 - published 2/24/2014 - effective 7/1/2014)
a. An erosion and sediment control plan from the appropriate VESCP authority as
authorized under the Erosion and Sediment Control Regulations (9VAC25-840),
unless the operator receives from the VESCP an "agreement in lieu of a plan" as
defined in 9VAC25-840-10 or prepares the erosion and sediment control plan in
accordance with annual standards and specifications approved by the department.
The operator of any land -disturbing activity that is not required to obtain erosion and
sediment control plan approval from a VESCP authority or is not required to adopt
department -approved annual standards and specifications shall submit the erosion
and sediment control plan to the department for review and approval; and
b. A stormwater management plan from the appropriate VSMP authority as
authorized under the Virginia Stormwater Management Program (VSMP) Regulation
(9VAC25-870), unless the operator prepares the stormwater management plan in
accordance with annual standards and specifications approved by the department.
The operator of any land -disturbing activity that is not required to obtain stormwater
management plan approval from a VSMP authority or is not required to adopt
department -approved annual standards and specifications shall submit the
stormwater management plan to the department for review and approval; and
5. The board has not notified the operator that the discharge is not eligible for coverage
in accordance with subsection B of this section.
B. The board will notify an operator that the discharge is not eligible for coverage under this
general permit in the event of any of the following:
1. The operator is required to obtain an individual permit in accordance with 9VAC25-
870-410 B;
2. The operator is proposing discharges to surface waters specifically named in other
board regulations that prohibit such discharges;
3. The discharge causes, may reasonably be expected to cause, or contributes to a
violation of water quality standards (9VAC25-260);
4. The discharge violates or would violate the antidegradation policy in the Water Quality
Standards (9VAC25-260-30) ; or
5. The discharge is not consistent with the assumptions and requirements of an
applicable TMDL approved prior to the term of this general permit.
C. 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:
1. The support activity is directly related to a construction activity that is required to have
general permit coverage for discharges of stormwater from construction activities;
2. The support activity is not a commercial operation , nor does it serve multiple
unrelated construction activities by different operators;
3. The support activity does not operate beyond the completion of the last construction
activity it supports;
4. The support activity is identified in the registration statement at the time of general
permit coverage;
5. Appropriate control measures are identified in a stormwater pollution prevention plan
and implemented to address the discharges from the support activity areas; and
6. All applicable, state, federal, and local approvals are obtained for the support activity.
D. Support activities located off -site are not required to be covered under this general
permit. Discharges of stormwater from off -site support activities may be authorized under
Page 3 of 29
9VAC25-880 (adopted 12/17/2013 - published 2/24/2014 - effective 7/1/2014)
another state or VPDES permit. Where stormwater discharges from off -site support activities
are not authorized under this general permit, the land area of the off -site support activity need
not be included in determining the total land disturbance acreage of the construction activity
seeking general permit coverage.
E. Discharges authorized by this general permit may be commingled with other sources of
stormwater that are not required to be covered under a state permit, so long as the commingled
discharge is in compliance with this general permit. Discharges authorized by a separate state
or VPDES permit may be commingled with discharges authorized by this general permit so long
as all such discharges comply with all applicable state and VPDES permit requirements.
F. Authorized nonstormwater discharges. The following nonstormwater discharges from
construction activities are authorized by this general permit:
1. Discharges from firefighting activities;
2. Fire hydrant flushings;
3. Water 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;
4. Water used to control dust that has been filtered, settled, or similarly treated prior to
discharge;
5. Potable water source, including uncontaminated waterline flushings;
6. 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;
7. Pavement wash water where spills or leaks of toxic or hazardous materials have not

materials such as solvents;
11. Uncontaminated, excavation dewatering, including dewatering of trenches and
excavations that have been filtered, settled, or similarly treated prior to discharge; and
12. Landscape irrigations.
G. Approval for coverage under this general permit does not relieve any operator of the
responsibility to comply with any other applicable federal, state or local statute, ordinance or
regulation.
H. Continuation of general permit coverage.
1. Any operator that was authorized to discharge under the general permit issued in
2009 and that submits a complete and accurate registration statement on or before June
30, 2014, is authorized to continue to discharge under the terms of the 2009 general
permit until such time as the board either:
a. Issues coverage to the operator under this general permit or
b. Notifies the operator that the discharge is not eligible for coverage under this
general permit.
2. When the operator is not in compliance with the conditions of the expiring or expired
general permit the board may choose to do any or all of the following:

permit, including but not limited to: (i) registration statement acceptance; (ii) fee collection; (iii)
stormwater management plan review and approval; and (iv) permit compliance and enforcement
dependent upon conditions established as part of the board approval.
9VAC25-880-50. General permit application (registration statement).
A. Deadlines for submitting registration statement. Any operator seeking coverage under
this general permit, and that is required to submit a registration statement, shall submit a
complete and accurate general VPDES permit registration statement in accordance with this
section, which shall serve as a notice of intent for coverage under the general VPDES permit for
discharges of stormwater from construction activities.
1. New construction activities.
a. Any operator proposing a new stormwater discharge from construction activities
shall submit a complete and accurate registration statement to the VSMP authority
prior to the commencement of land disturbance.
b. Any operator proposing a new stormwater discharge from construction activities in
response to a public emergency where the related work requires immediate
authorization to avoid imminent endangerment to human health or the environment is
authorized to discharge under this general permit, provided that:
(1) The operator submits a complete and accurate registration statement to the
VSMP authority no later than 30 days after commencing land disturbance; and
(2) Documentation to substantiate the occurrence of the public emergency is
provided with the registration statement.

month and shall be during normal business hours. Information not required to be
contained within the SWPPP by this general permit is not required to be released.
E. SWPPP implementation. The operator shall implement the SWPPP and subsequent
amendments, modifications, and updates from commencement of land disturbance until
termination of general permit coverage as specified in Part I F.
1. All control measures must be properly maintained in effective operating condition in
accordance with good engineering practices and, where applicable, manufacturer
specifications. If a site inspection required by Part II F identifies a control measure that is
not operating effectively, corrective action(s) shall be completed as soon as practicable,
but no later than seven days after discovery or a longer period as established by the
VSMP authority, to maintain the continued effectiveness of the control measures.
2. If site inspections required by Part II F identify an existing control measure that needs
to be modified or if an additional control measure is necessary for any reason,
implementation shall be completed prior to the next anticipated measurable storm event.
If implementation prior to the next anticipated measurable storm event is impracticable,
then alternative control measures shall be implemented as soon as practicable, but no
later than seven days after discovery or a longer period as established by the VSMP
authority.
F. SWPPP Inspections.

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 manager is authorized to make management
decisions that govern the operation of the regulated facility including having the
Page 24 of 29
9VAC25-880 (adopted 12/17/2013 - published 2/24/2014 - effective 7/1/2014)
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, etc. 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 must
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 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
Page 25 of 29
9VAC25-880 (adopted 12/17/2013 - published 2/24/2014 - effective 7/1/2014)
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 90 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.
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
Page 26 of 29
9VAC25-880 (adopted 12/17/2013 - published 2/24/2014 - effective 7/1/2014)
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.
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(s) of the upset;
b. The permitted facility was at the time being properly operated;

9VAC25-880 (adopted 12/17/2013 - published 2/24/2014 - effective 7/1/2014)
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 must be kept under the conditions of this general permit;
2. Have access to and copy, at reasonable times, any records that must 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.
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 permits 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 permits.
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.
2. 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.
