MINIMUM STANDARDS (MS)
All applicable Virginia Erosion and Sediment Control Regulations and Minimum
Standards shall be adhered to during all phases of construction. These
include, but are not limited to the following:
1. STABLIZATION OF DENUDED AREAS:
Permanent or temporary soil stabilization shall be applied to bare 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 or
undisturbed for longer than 7 days. Permanent stabilization shall be
applied at areas that are to be left dormant for more than 1 year.
2. STABILIZATION OF SOIL STOCKPILES:
During construction of the project, soil stockpiles shall be stabilized or
protected with sediment trapping measures. The applicant is responsible for
temporary protection and permanent stabilization of all soil stockpiles on
site as well as soil intentionally transported from the project site.
3.PERMANENT VEGETATIVE COVER
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 achieve that, in the opinion
of the city Inspector, is uniform and mature enough to survive to inhibit
erosion.
4. TIMING & STABILIZATION OF SILT TRAPPING MEASURES:
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
and disturbance takes place.
5. STABILIZATION OF EARTHEN STRUCTURES:
Stabilization measures shall be applied to earthen structures such as
dams, dikes and diversions immediately after installation.
6.SEDIMENT TRAPS AND BASINS:
A sediment basin shall control surface runoff from disturbed areas that is
comprised of flow from drainage areas greater than or equal to three acres.
The sediment basin shall be designed and constructed to accommodate the
anticipated sediment loading for the land disturbing activity. The outfoll
device or system device shall take into account the total drainage area
flowing through the disturbed area to be served by the basin.
7. CUT AND FILL SLOPES:
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.
& CONCENTRATED RUN-OFF DOWN CUT OR FILL SLOPES:
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.WATER SEEPS FROM A SLOPE FACE:
Whenever water seeps from a slope face, adequate drainage or other
protection shall be provided.
10. STORM SEWER INLET PROTECTION:
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. STABILIZATION OF OUTLETS:
Before newly constructed stormwater conveyance channels 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. WORK IN LIVE WATERCOURSES:
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. Nonerodible
material shall be used for the construction of causeways and cofferdams.
Earthen fill may be used for these structures if armored by nonerodible
cover materials.
13. CROSSING A LIVE WATERCOURSE:
When a live watercourse must be crossed by construction vehicles more
than twice in any six month period, a temporary stream crossing
constructed of nonerodible materials shall be provided.
14. APPLICABLE REGULATIONS:
All applicable federal, state and local regulations pertaining to working in
or crossing live watercourses shall be met.
15. STABILIZATION OF BED AND BANKS
The bed and banks of a watercourse shall be stabilized immediately after
work in the watercourse is completed.
16. UNDERGROUND UTILITIES:
Underground utilities shall be installed in accordance with the following
standards in addition to other criteria:
a.No more than 500 linear feet of trench may be opened at one time
b.Excavated material shall be placed on the uphill side of trenches
c.Effluent for dewatering operations shall be filtered or passed through
approved sediment trapping device, or both, and discharged in a manner
that does not adversely affect flowing streams or offsite property.
d.Material used for backfilling trenches shall be properly compacted in order
to minimize erosion and promote stabilization.
e.Restabilization shall be accomplished in accordance with these regulations.
f. Applicable safety regulations shall be complied with.
17.CONSTRUCTION ACCESS ROUTES:
Where construction vehicle access routes intersect paved public roads,
provisions shall be made to minimize the transport of sediment by vehicular
tracking onto paved surfaces. Where sediment is transported on to a
public road surface, the road shall be cleaned thoroughly at the end of
each day. Sediment shall be removed 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 lots as well as to larger land disturbing activities.
18.TEMPORARY E&S CONTROL MEASURE REMOVAL:
All temporary erosion and sediment control measures shall be removed
within 30 days after final site stabilization or after temporary measures are
no longer needed, unless otherwise authorized by the local program
authority. Trapped sediment and the disturbed soil areas resulting from the
disposition of temporary measures shall be permanently stabilized to prevent
further erosion and sediment.
19.ADEQUACY OF RECEIVING CHANNELS:
Properties and waterways downstream from the development site shall be
protected from sediment deposition, erosion and damage, due to increases
in volume, velocity and peak flow rates of stormwater runoff for the stated
frequency storm of 24-hour duration.

Stormwater Quantity is managed on site through the utilization of sheet flow where possible & by providing (2) two
level spreaders which will allow concentrated flow to leave the site in sheet flow conditions. Downstream properties
have been evaluated for potential impacts from increased sheetflow volume and it was determined that the minor
increase in sheetflow will not cause erosion of downstream channels or flooding.

F. Response and reporting practices
Minimize discharges from spills and leaks. Minimize the discharge of pollutants from spills and leaks and
implement chemical spill and leak prevention and response procedures as follows. To the extent practical, do
not store oils, chemicals, or other potential contaminants on site. When storage of potential contaminants is
required, provide secondary containment, such as spill berms or spill containment pallets. These should be
located within the drainage areas to a sediment trap or sediment basin. Direct concrete wash water into a settling
basin, dispose of hardened concrete with other construction waste debris to an appropriate waste facility.
Respond to all spills, leaks and discharges as follows. Spills of oil, petroleum products, sanitary wastes, and
substances listed under 40 CFR parts 110, 117, and 302 should be cleaned up as soon as possible while
protecting worker safety. Construct an earthen dike around any spills on dirt to prevent spreading. If a spill
occurs during rainfall, cover it with a tarp or another impermeable cover to prevent contaminating runoff. Do
not bury any spills or wash them with water. Maintain a spill kits in a readily accessible location. A spill kit
shall consist of a lined drum with bags of universal sorbents in the bottom, accessible without tipping the drum,
sorbent socks above the bags, and personal protective equipment on the top. All materials used to remove the
contaminants, including any water used to rinse equipment, and all dirt removed must be treated as
contaminated. Textiles, such as from coveralls, may be sent to a certified laundry facility. Waste must be
disposed of according to the standards of The City of Charlottesville and the Commonwealth of Virginia. Store
hazardous materials and wastes in covered containers.
Report all spills, leaks and discharges as follows: All spills, leaks, and discharges shall be recorded in the
inspection logs. If construction activity results in a discharge of contaminants that may be reasonably expected
to enter surface waters, the operator shall notify the Department of Environmental Quality immediately or
within 24 hours, and shall submit a written report within five days. For significant spills that cannot be
controlled by personnel in the immediate vicinity, notify the local emergency response by dialing 911. The City
of Charlottesville must also be notified, and potentially some of the following agencies: the Fire Department,
the Public Works Department, the Coast Guard, the Highway Patrol, the County Police Department,
Department of Toxic Substances, OSHA, etc. For spills of federal reportable quantities, in conformance with
the requirements in 40 CFR parts 110, 119, and 302, the contractor should notify the National Response Center
at (800) 424-8802.
G. Pollution Prevention Awareness
The engineer, project superintendent, and contractor shall have weekly meetings to review on -site conditions
and advise contractor of potential risks that should be addressed. Contractor will be responsible for following
procedures on a daily basis and applying appropriate waste management and prevention practices to be in
compliance with the conditions of the general permit. Employees shall be informed of the danger to nature and
to human health of various chemical spills.

GENERAL VPDES PERMIT FOR DISCHARGES OF
STORMWATER FROM CONSTRUCTION ACTIVITIES
AUTHORIZATION TO DISCHARGE UNDER THE VIRGINIA STORMWATER MANAGEMENT
PROGRAM AND THE VIRGINIA STORMWATER MANAGEMENT ACT
In compliance with the provisions of the Clean Water Act, as amended, and pursuant to the
Virginia Stormwater Management Act and regulations adopted pursuant thereto, operators of
construction activities are authorized to discharge to surface waters within the boundaries of the
Commonwealth of Virginia, except those specifically named in State Water Control Board
regulations that prohibit such discharges.
The authorized discharge shall be in accordance with the registration statement filed with the
Department of Environmental Quality, this cover page, Part I - Discharge Authorization and
Special Conditions, Part II - Stormwater Pollution Prevention Plan, and Part III - Conditions
Applicable to All VPDES Permits as set forth in this general permit.

DISCHARGE AUTHORIZATION AND SPECIAL CONDITIONS
A. Coverage under this general permit.
During the period beginning with the date of coverage under this general permit and lasting
until the general permit's expiration date, the operator is authorized to discharge stormwater
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.
Discharges mixed with nonstormwater. This general permit does not authorize discharges that
are mixed with sources of nonstormwater, other than those discharges that are identified in
Part I E (Authorized nonstormwater discharges) and are in compliance with this general
permit.
Discharges covered by another state permit. This general permit does not authorize
discharges of stormwater from construction activities that have been covered under an
individual permit or required to obtain coverage under an alternative general permit.
Page 3 of 26
4. Impaired waters and total maximum daily load (TMDL) limitation.

g. The locations where any additional control measure is needed;
h. 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;
i. Documentation of any corrective actions required from a previous inspection that have not
been implemented; and
The date and signature of the qualified personnel and the operator or its duly authorized
representative.
5. The inspection report shall be included into the SWPPP no later than four business days after
the inspection is complete.
The inspection report and any actions taken in accordance with Part II shall be retained by
the operator as part of the SWPPP for at least three years from the date that general permit
coverage expires or is terminated. The inspection report shall identify any incidents of
noncompliance. Where an inspection report does not identify any incidents of noncompliance,
the report shall contain a certification that the construction activity is in compliance with the
SWPPP and this general permit. The report shall be signed in accordance with Part III K of
this general permit.
H. Corrective actions.
The operator shall implement the corrective actions identified as a result of an inspection as
soon as practicable but no later than seven days after discovery or a longer period as
approved by the VSMP authority. If approval of a corrective action by a regulatory authority
(e.g., VSMP authority, VESCP authority, or the department) is necessary, additional control
measures shall be implemented to minimize pollutants in stormwater discharges until such
approvals can be obtained.
The operator may be required to remove accumulated sediment deposits located outside of
the construction activity covered by this general permit as soon as practicable in order to
minimize environmental impacts. The operator shall notify the VSMP authority and the
department as well as obtain all applicable federal, state, and local authorizations,
approvals, and permits prior to the removal of sediments accumulated in surface waters
including wetlands.

1. The operator shall update the SWPPP to include the results of the monitoring as may be
performed in accordance with this general permit, unless another reporting schedule is
specified elsewhere in this general permit.
2. Monitoring results shall be reported on a discharge monitoring report (DMR); on forms
provided, approved or specified by the department; or in any format provided that the date,
location, parameter, method, and result of the monitoring activity are included.
If the operator monitors any pollutant specifically addressed by this general permit more
frequently than required by this general permit using test procedures approved under 40 CFR
Part 136 or using other test procedures approved by the U.S. Environmental Protection
Agency or using procedures specified in this general permit, the results of this monitoring shall
be included in the calculation and reporting of the data submitted in the DMR or reporting form
specified by the department.
4. Calculations for all limitations which require averaging of measurements shall utilize an
arithmetic mean unless otherwise specified in this general permit.
D. Duty to provide information. The operator shall furnish, within a reasonable time, any
information which the board may request to determine whether cause exists for terminating this
general permit coverage or to determine compliance with this general permit. The board,
department, EPA, or VSMP authority may require the operator to furnish, upon request, such
plans, specifications, and other pertinent information as may be necessary to determine the effect
of the wastes from his discharge on the quality of surface waters, or such other information as
may be necessary to accomplish the purposes of the CWA and the Virginia Stormwater
Management Act. The operator shall also furnish to the board, department, EPA, or VSMP
authority, upon request, copies of records required to be kept by this general permit.
E. Compliance schedule reports. Reports of compliance or noncompliance with, or any progress
reports on, interim and final requirements contained in any compliance schedule of this general
permit shall be submitted no later than 14 days following each schedule date.
F. Unauthorized stormwater discharges. Pursuant to § 62.1-44.5 of the Code of Virginia, except
in compliance with a state permit issued by the department, it shall be unlawful to cause a
stormwater discharge from a construction activity.
G. Reports of unauthorized discharges. Any operator who discharges or causes or allows a
discharge of sewage, industrial waste, other wastes or any noxious or deleterious substance or a
hazardous substance or oil in an amount equal to or in excess of a reportable quantity established
under either 40 CFR Part 110, 40 CFR Part 117, 40 CFR Part 302, or § 62.1-44.34:19 of the Code
of Virginia that occurs during a 24-hour period into or upon surface waters or who discharges or
causes or allows a discharge that may reasonably be expected to enter surface waters, shall
notify the Department of Environmental Quality of the discharge immediately upon discovery of
the discharge, but in no case later than within 24 hours after said discovery. A written report of
the unauthorized discharge shall be submitted to the department and the VSMP authority within
five days of discovery of the discharge. The written report shall contain:
1. A description of the nature and location of the discharge;
2. The cause of the discharge;
Page 20 of 26
3. The date on which the discharge occurred;
4. The length of time that the discharge continued;
5. The volume of the discharge;
6. If the discharge is continuing, how long it is expected to continue;
7. If the discharge is continuing, what the expected total volume of the discharge will be; and
Any steps planned or taken to reduce, eliminate and prevent a recurrence of the present
discharge or any future discharges not authorized by this general permit.
Discharges reportable to the department and the VSMP authority under the immediate reporting
requirements of other regulations are exempted from this requirement.
H. Reports of unusual or extraordinary discharges. If any unusual or extraordinary discharge
including a "bypass" or "upset," as defined in this general permit, should occur from a facility and
the discharge enters or could be expected to enter surface waters, the operator shall promptly
notify, in no case later than within 24 hours, the department and the VSMP authority by telephone
after the discovery of the discharge. This notification shall provide all available details of the
incident, including any adverse effects on aquatic life and the known number of fish killed. The
operator shall reduce the report to writing and shall submit it to the department and the VSMP
authority within five days of discovery of the discharge in accordance with Part III 12. Unusual
and extraordinary discharges include any discharge resulting from:
1. Unusual spillage of materials resulting directly or indirectly from processing operations;
2. Breakdown of processing or accessory equipment;
3. Failure or taking out of service of some or all of the facilities; and
4. Flooding or other acts of nature.
I. Reports of noncompliance. The operator shall report any noncompliance which may adversely
affect surface waters or may endanger public health.
An oral report to the department and the VSMP authority shall be provided within 24 hours
from the time the operator becomes aware of the circumstances. The following shall be
included as information that shall be reported within 24 hours under this subdivision:
a. Any unanticipated bypass; and
b. Any upset that causes a discharge to surface waters.
2. A written report shall be submitted within five days and shall contain:
a. A description of the noncompliance and its cause;
Page 21 of 26
b. The period of noncompliance, including exact dates and times, and if the noncompliance
has not been corrected, the anticipated time it is expected to continue; and
c. Steps taken or planned to reduce, eliminate, and prevent reoccurrence of the
noncompliance.
The department may waive the written report on a case -by -case basis for reports of
noncompliance under Part III I if the oral report has been received within 24 hours and no
adverse impact on surface waters has been reported.
3. The operator shall report all instances of noncompliance not reported under Part III 1 1 or 2 in
writing as part of the SWPPP. The reports shall contain the information listed in Part 111 1 2.
NOTE: The reports required in Part III G, H and I shall be made to the department and the VSMP
authority. Reports may be made by telephone, email, or by fax. For reports outside normal working
hours, leaving a recorded message shall fulfill the immediate reporting requirement. For
emergencies, the Virginia Department of Emergency Management maintains a 24-hour telephone
service at 1-800-468-8892.
4. Where the operator becomes aware of a failure to submit any relevant facts, or submittal of
incorrect information in any report, including a registration statement, to the department or the
VSMP authority, the operator shall promptly submit such facts or correct information.
J. Notice of planned changes.
1. The operator shall give notice to the department and the VSMP authority as soon as possible
of any planned physical alterations or additions to the permitted facility or activity. Notice is
required only when:
a. The operator plans an alteration or addition to any building, structure, facility, or installation
that may meet one of the criteria for determining whether a facility is a new source in
9VAC25-870-420;
b. The operator plans an alteration or addition that would significantly change the nature or
increase the quantity of pollutants discharged. This notification applies to pollutants that
are not subject to effluent limitations in this general permit; or
2. The operator shall give advance notice to the department and VSMP authority of any planned
changes in the permitted facility or activity, which may result in noncompliance with state
permit requirements.
K. Signatory requirements.
1. Registration statement. All registration statements shall be signed as follows:
a. For a corporation: by a responsible corporate officer. For the purpose of this chapter, a
responsible corporate officer means: (i) a president, secretary, treasurer, or vice-president
of the corporation in charge of a principal business function, or any other person who
performs similar policy -making or decision -making functions for the corporation; or (ii) the
manager of one or more manufacturing, production, or operating facilities, provided the
Page 22 of 26
manager is authorized to make management decisions that govern the operation of the
regulated facility including having the explicit or implicit duty of making major capital
investment recommendations, and initiating and directing other comprehensive measures
to assure long-term compliance with environmental laws and regulations; the manager
can ensure that the necessary systems are established or actions taken to gather
complete and accurate information for state permit application requirements; and where
authority to sign documents has been assigned or delegated to the manager in
accordance with corporate procedures;
b. For a partnership or sole proprietorship: by a general partner or the proprietor,
respectively; or
c. For a municipality, state, federal, or other public agency: by either a principal executive
officer or ranking elected official. For purposes of this chapter, a principal executive officer
of a public agency includes (i) the chief executive officer of the agency or (ii) a senior
executive officer having responsibility for the overall operations of a principal geographic
unit of the agency.
2. Reports and other information. All reports required by this general permit, including SWPPPs,
and other information requested by the board or the department shall be signed by a person
described in Part III K 1 or by a duly authorized representative of that person. A person is a
duly authorized representative only if:
a. The authorization is made in writing by a person described in Part III K 1;
b. The authorization specifies either an individual or a position having responsibility for the
overall operation of the regulated facility or activity such as the position of plant manager,
operator of a well or a well field, superintendent, position of equivalent responsibility, or
an individual or position having overall responsibility for environmental matters for the
operator. (A duly authorized representative may thus be either a named individual or any
individual occupying a named position); and
c. The signed and dated written authorization is included in the SWPPP. A copy shall be
provided to the department and VSMP authority, if requested.
3. Changes to authorization. If an authorization under Part III K 2 is no longer accurate because
a different individual or position has responsibility for the overall operation of the construction
activity, a new authorization satisfying the requirements of Part III K 2 shall be submitted to
the VSMP authority as the administering entity for the board prior to or together with any
reports or information to be signed by an authorized representative.
4. Certification. Any person signing a document under Part III K 1 or 2 shall make the following
certification:
"I certify under penalty of law that I have read and understand this document and that this
document and all attachments were prepared in accordance with a system designed to assure
that qualified personnel properly gathered and evaluated the information submitted. Based on
my inquiry of the person or persons who manage the system, or those persons directly
responsible for gathering the information, the information submitted is, to the best of my
knowledge and belief, true, accurate, and complete. I am aware that there are significant
Page 23 of 26
penalties for submitting false information, including the possibility of fine and imprisonment for
knowing violations."
L. Duty to comply. The operator shall comply with all conditions of this general permit. Any state
permit noncompliance constitutes a violation of the Virginia Stormwater Management Act and the
Clean Water Act, except that noncompliance with certain provisions of this general permit may
constitute a violation of the Virginia Stormwater Management Act but not the Clean Water Act.
Permit noncompliance is grounds for enforcement action; for state permit coverage, termination,
revocation and reissuance, or modification; or denial of a state permit renewal application.
The operator shall comply with effluent standards or prohibitions established under § 307(a)
of the Clean Water Act for toxic pollutants within the time provided in the regulations that establish
these standards or prohibitions or standards for sewage sludge use or disposal, even if this
general permit has not yet been modified to incorporate the requirement.
M. Duty to reapply. If the operator wishes to continue an activity regulated by this general permit
after the expiration date of this general permit, the operator shall submit a new registration
statement at least 60 days before the expiration date of the existing general permit, unless
permission for a later date has been granted by the board. The board shall not grant permission
for registration statements to be submitted later than the expiration date of the existing general
permit.
N. Effect of a state permit. This general permit does not convey any property rights in either real
or personal property or any exclusive privileges, nor does it authorize any injury to private property
or invasion of personal rights, or any infringement of federal, state or local law or regulations.
O. State law. Nothing in this general permit shall be construed to preclude the institution of any
legal action under, or relieve the operator from any responsibilities, liabilities, or penalties
established pursuant to any other state law or regulation or under authority preserved by § 510 of
the Clean Water Act. Except as provided in general permit conditions on "bypassing" (Part III U)
and "upset' (Part III V), nothing in this general permit shall be construed to relieve the operator
from civil and criminal penalties for noncompliance.
P. Oil and hazardous substance liability. Nothing in this general permit shall be construed to
preclude the institution of any legal action or relieve the operator from any responsibilities,
liabilities, or penalties to which the operator is or may be subject under §§ 62.1-44.34:14 through
62.1-44.34:23 of the State Water Control Law or § 311 of the Clean Water Act.
Q. Proper operation and maintenance. The operator shall at all times properly operate and
maintain all facilities and systems of treatment and control (and related appurtenances), which
are installed or used by the operator to achieve compliance with the conditions of this general
permit. Proper operation and maintenance also includes effective plant performance, adequate
funding, adequate staffing, and adequate laboratory and process controls, including appropriate
quality assurance procedures. This provision requires the operation of back-up or auxiliary
facilities or similar systems, which are installed by the operator only when the operation is
necessary to achieve compliance with the conditions of this general permit.
R. Disposal of solids or sludges. Solids, sludges or other pollutants removed in the course of
treatment or management of pollutants shall be disposed of in a manner so as to prevent any
pollutant from such materials from entering surface waters and in compliance with all applicable
state and federal laws and regulations.
Page 24 of 26
S. Duty to mitigate. The operator shall take all steps to minimize or prevent any discharge in
violation of this general permit that has a reasonable likelihood of adversely affecting human
health or the environment.
T. Need to halt or reduce activity not a defense. It shall not be a defense for an operator in an
enforcement action that it would have been necessary to halt or reduce the permitted activity in
order to maintain compliance with the conditions of this general permit.
U. Bypass.
1. 'Bypass," as defined in 9VAC25-870-10, means the intentional diversion of waste streams
from any portion of a treatment facility. The operator may allow any bypass to occur that does
not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to
ensure efficient operation. These bypasses are not subject to the provisions of Part III U 2 and
3.
2. Notice.
a. Anticipated bypass. If the operator knows in advance of the need for a bypass, the
operator shall submit prior notice to the department, if possible at least 10 days before the
date of the bypass.
b. Unanticipated bypass. The operator shall submit notice of an unanticipated bypass as
required in Part III I.
3. Prohibition of bypass.
a. Except as provided in Part III U 1, bypass is prohibited, and the board or department may
take enforcement action against an operator for bypass unless:
(1) Bypass was unavoidable to prevent loss of life, personal injury, or severe property
damage. Severe property damage means substantial physical damage to property,
damage to the treatment facilities that causes them to become inoperable, or
substantial and permanent loss of natural resources that can reasonably be expected
to occur in the absence of a bypass. Severe property damage does not mean
economic loss caused by delays in production;
(2) There were no feasible alternatives to the bypass, such as the use of auxiliary
treatment facilities, retention of untreated wastes, or maintenance during normal
periods of equipment downtime. This condition is not satisfied if adequate back-up
equipment should have been installed in the exercise of reasonable engineering
judgment to prevent a bypass that occurred during normal periods of equipment
downtime or preventive maintenance; and
(3) The operator submitted notices as required under Part III U 2.
b. The department may approve an anticipated bypass, after considering its adverse effects,
if the department determines that it will meet the three conditions listed in Part III U 3 a.
Page 25 of 26
V. Upset.
1. An "upset," as defined in 9VAC25-870-10, means an exceptional incident in which there is
unintentional and temporary noncompliance with technology -based state permit effluent
limitations because of factors beyond the reasonable control of the operator. An upset does
not include noncompliance to the extent caused by operational error, improperly designed
treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or
careless or improper operation.
2. An upset constitutes an affirmative defense to an action brought for noncompliance with
technology -based state permit effluent limitations if the requirements of Part III V 4 are met.
A determination made during administrative review of claims that noncompliance was caused
by upset, and before an action for noncompliance, is not a final administrative action subject
to judicial review.
3. An upset does not include noncompliance to the extent caused by operational error,
improperly designed treatment facilities, inadequate treatment facilities, lack of preventative
maintenance, or careless or improper operation.
4. An operator who wishes to establish the affirmative defense of upset shall demonstrate,
through properly signed, contemporaneous operating logs or other relevant evidence that:
a. An upset occurred and that the operator can identify the cause of the upset;
b. The permitted facility was at the time being properly operated;
c. The operator submitted notice of the upset as required in Part III I; and
d. The operator complied with any remedial measures required under Part III S.
5. In any enforcement proceeding, the operator seeking to establish the occurrence of an upset
has the burden of proof.
W. Inspection and entry. The operator shall allow the department as the board's designee, the
VSMP authority, EPA, or an authorized representative of either entity (including an authorized
contractor), upon presentation of credentials and other documents as may be required by law to:
1. Enter upon the operator's premises where a regulated facility or activity is located or
conducted, or where records shall be kept under the conditions of this general permit;
2. Have access to and copy, at reasonable times, any records that shall be kept under the
conditions of this general permit;
3. Inspect and photograph at reasonable times any facilities, equipment (including monitoring
and control equipment), practices, or operations regulated or required under this general
permit; and
4. Sample or monitor at reasonable times, for the purposes of ensuring state permit compliance
or as otherwise authorized by the Clean Water Act or the Virginia Stormwater Management
Act, any substances or parameters at any location.
Page 26 of 26
For purposes of this section, the time for inspection shall be deemed reasonable during regular
business hours, and whenever the facility is discharging. Nothing contained herein shall make an
inspection unreasonable during an emergency.
X. State permit actions. State permit coverage may be modified, revoked and reissued, or
terminated for cause. The filing of a request by the operator for a state permit modification,
revocation and reissuance, or termination, or a notification of planned changes or anticipated
noncompliance does not stay any state permit condition.
Y. Transfer of state permit coverage.
1. State permits are not transferable to any person except after notice to the department. Except
as provided in Part III Y 2, a state permit may be transferred by the operator to a new operator
only if the state permit has been modified or revoked and reissued, or a minor modification
made, to identify the new operator and incorporate such other requirements as may be
necessary under the Virginia Stormwater Management Act and the Clean Water Act.
As an alternative to transfers under Part III Y 1, this state permit may be automatically
transferred to a new operator if:
a. The current operator notifies the department at least 30 days in advance of the proposed
transfer of the title to the facility or property;
b. The notice includes a written agreement between the existing and new operators
containing a specific date for transfer of state permit responsibility, coverage, and liability
between them; and
c. The department does not notify the existing operator and the proposed new operator of
its intent to modify or revoke and reissue the state permit. If this notice is not received, the
transfer is effective on the date specified in the agreement mentioned in Part III Y 2 b.
3. For ongoing construction activity involving a change of operator, the new operator shall accept
and maintain the existing SWPPP, or prepare and implement a new SWPPP prior to taking
over operations at the site.
Z. Severability. The provisions of this general permit are severable, and if any provision of this
general permit or the application of any provision of this state permit to any circumstance, is held
invalid, the application of such provision to other circumstances and the remainder of this general
permit shall not be affected thereby.
