Submitted by
Virginia Department of Environmental Quality
Prepared by
THE Louis Berger Group, INC.

DC 20037
Final Report
March 2008
Executive Summary
This report presents the development of bacteria TMDLs for the Rivanna River
mainstem, North Fork Rivanna River, Preddy Creek and tributaries, Meadow Creek,
Mechums River, and Beaver Creek watersheds. These water bodies were listed as
impaired on Virginia's 303(d) Total Maximum Daily Load Priority List and Reports
(DEQ, 1998, 2002, 2004, 2006) because of violations of the state's water quality
standards for E. coli and for fecal coliform bacteria.
Description of the Study Area
The bacteria impaired Rivanna River watershed is located within the borders of
Albemarle, Greene, Nelson, and Orange counties. The city of Charlottesville is also
within the watershed's boundaries. All impaired streams are located in the Rivanna River
watershed (USGS Cataloging Unit 02080204). The entire Rivanna River bacteria
impaired watershed is approximately 321,877 acres.
Impairment Description
Segments of the Rivanna River mainstem, North Fork Rivanna River, Preddy Creek and
tributaries, Meadow Creek, Mechums River, and Beaver Creek were listed as bacteria
impaired on Virginia's 2002, 2004, and/or 2006 303(d) Total Maximum Daily Load
Priority List and Reports due to violations of the state's water quality standard for fecal
coliform bacteria and/or E. coh. The impaired segments are located in the Rivanna River
Basin in central Virginia. The watershed is located in the hydrologic unit (HUC)
02080204. The impaired watersheds include the City of Charlottesville and portions of
Albemarle, Greene, Orange, and Nelson counties.
The impaired segment of the Rivanna River (VAV-H28R-RVNOIA00) extends 5.28
miles along the mainstem from the confluence of the North Fork Rivanna River to
Moores Creek. This segment of the Rivanna River was first listed on the 2006
305(b)/303(d) Water Quality Assessment Integrated Report for exceedances of the E. coli
standard. During the 2006 assessment period (January 200 through December 2004), 2
Executive Summary E-1
out of 9 samples (22%) collected at listing station 2-RVN037.54 exceeded the E. coli
criterion of 235 cfu/100 ml
The impaired segment of Beaver Creek (VAV-H23R-BVR02AO4) extends 4.8 miles
from its headwaters to Beaver Creek Reservoir. This segment of Beaver Creek was first
listed on the 2004 305(b)/303(d) Water Quality Assessment Integrated Report for
exceedances of the fecal coliform standard. During the 2004 assessment period (January
1998 through December 2002), 2 out of 16 fecal coliform samples (13%) collected at
listing station 2-BVR005.70 exceeded the fecal coliform standard instantaneous of 400
cfu/100 MI. This segment remained on the 303(d) list in the 2006 Water Quality
Assessment Report.
The impaired segment of Meadow Creek (VAV-H28R-MWCOIA00) extends 4.01 miles
from its headwaters to the confluence of the Rivanna River. This segment of Meadow
Creek was first listed on the 2002 303(d) Water Quality Assessment Integrated Report for
exceedances of the fecal coliform standard. During the 2002 assessment period (January
1996 through December 2000), 4 out of 23 fecal colifonn samples (17%) collected at
listing station 2-MWC000.60 exceeded the fecal coliform instantaneous standard of 400
cfu/100 MI.
The impaired segment of the Mechums River (VAV-H23R-MCMOIA00) extends 10.44

During this same period, only 1 out of the 9 samples (11%) collected at listing station 2-
PRD004.42 exceeded the E. coli criterion of 235 cfu/100 ml.
Applicable Water Quality Standards
At the time of the initial listing of Rivanna River mainstem, North Fork Rivanna River,
Preddy Creek and tributaries, Meadow Creek, Mechums River, and Beaver Creek
segments, the Virginia Bacteria Water Quality Standard was expressed in fecal coliform
bacteria; however, the bacteria water quality standard has recently been changed, and is
now expressed in E. coh. Virginia's bacteria water quality standard currently states that
E. coli bacteria shall not exceed a geometric mean of 126 E. coh counts per 100 mL of
water for two or more samples within a calendar month, or an E. coh concentration of
235 counts per 100 mL of water at any time. However, the loading rates for watershed -
based modeling are available only in terms of the previous standard, fecal coliform
bacteria. Therefore, the TMDL was expressed in E. coli by converting modeled daily
fecal coliform concentrations to daily E. coh concentrations using an in -stream translator.
This TMDL was required to meet both the geometric mean and instantaneous E. colt
water quality standard.
Watershed Characterization
The land use characterization for the Rivanna River watershed was based on a
combination of land cover data from the National Land Use Land cover data set (NLCD)
using 2001 reference data and the Virginia Department of Forestry 2005 land use data.
Executive Summary E-3
Dominant land uses in the watershed are forest (64%) and agriculture (21%). These
account for a combined 85% of the total land area in the watershed
The potential sources of fecal coliform include run-off from livestock grazing, manure
applications, industrial processes, residential, and domestic pets waste. Some of these
sources are driven by dry weather and others are driven by wet weather. The potential
sources of fecal coliform in the watershed were identified and characterized. These
sources include permitted point sources, failed septic systems and straight pipes,
livestock, wildlife, and pets.
TMDL Technical Approach
The Hydrologic Simulation Program -Fortran (HSPF) model was selected and used as a
tool to predict the in -stream water quality conditions of the delineated watershed under
varying scenarios of rainfall and fecal coliform loading. HSPF is a hydrologic,
watershed -based water quality model. The results from the model were used to develop
the TMDL allocations based on the existing fecal coliform load. Basically, this means
that HSPF can explicitly account for the specific watershed conditions, the seasonal
variations in rainfall and climate conditions, and activities and uses related to fecal
coliform loading.
The modeling process in HSPF starts with the following steps
e delineating the watershed into smaller subwatersheds
e entering the physical data that describe each subwatershed and stream segment
e entering values for the rates and constants that describe the sources and the
activities related to the fecal coliform loading in the watershed
The Rivanna River watershed was delineated into 41 smaller subwatersheds to represent
the watershed characteristics and to improve the accuracy of the HSPF model. Of these
41 representing the entire Rivanna River watershed, 28 were within the bacteria impaired
watershed. This delineation was based on topographic characteristics, and was created
using a Digital Elevation Model (DEM), stream reaches obtained from the National
Hydrography Dataset (NHD), and stream flow and in -stream water quality data.
Executive Summary E-4
Stream flow data were available from the U.S. Geological Survey (USGS). Weather data
were obtained from the National Climatic Data Center (NCDC). The data used in the
model include meteorological data (hourly precipitation) and surface airways data
(including wind speed/direction, ceiling height, dry bulb temperature, dew point
temperature, and solar radiation).
The period of January 1998 to December 2006 was used for HSPF hydraulic calibration
and validation. The hydrologic calibration parameters were adjusted until there was a
good agreement between the observed and simulated stream flow, thereby indicating that
the model parameterization is representative of the hydrologic characteristics of the study
areas. The model results closely matched the observed flows during low flow conditions,
base flow recession and storm peaks.
Instream water quality data for the calibration was retrieved from DEQ, and was
evaluated for potential use in the set-up, calibration, and validation of the water quality
model. The existing fecal coliform loading was calculated based on current watershed
conditions. Since Virginia has recently changed its bacteria standard from fecal coliform
to E. coli the modeled fecal coliform concentrations were changed to E. coli
concentrations using a translator.
TMDL Calculations
The TMDL represents the maximum amount of a pollutant that the stream can receive
without exceeding the water quality standard. The load allocation for the selected
scenarios was calculated using the following equation:
Where,
TMDL = E WLA +2] LA + MOS
WLA = wasteload allocation (point source contributions);
LA = load allocation (non -point source allocation); and
MOS = margin of safety.
Executive Summary E-5
The margin of safety (MOS) is a required component of the TMDL to account for any
lack of knowledge concerning the relationship between effluent limitations and water
quality. The MOS was implicitly incorporated in this TMDL. Implicitly incorporating
the MOS required that allocation scenarios be designed to meet a 30-day geometric mean
E. coli standard of 126 cfu/100 mL and the instantaneous E. coli standard of 235 cf i/100
mL with 0% exceedance.
Typically, there are several potential allocation strategies that would achieve the TMDL
endpoint and water quality standards. A number of load allocation scenarios were
developed to determine the final TMDL load allocation scenario.
For the hydrologic period of January 2000 to December 2006, fecal coliform loading and
instream fecal coliform concentrations were estimated for the various scenarios using the
developed HSPF model of the Rivanna River mainstem, North Fork Rivanna River,
Preddy Creek and tributaries, Meadow Creek, Mechums River, and Beaver Creek. After
using the instream translator, the TMDL allocation plan was developed to meet geometric
mean and instantaneous E. coli standards. Based on the load -allocation scenario
analyses, the daily TMDL allocation plans that will meet the 30-day E. coli geometric
mean water quality standard of 126 cfu/100 mL and the instantaneous E. coli water
quality standard of 235 cfu/100 mL are presented in Table E-1.

TMDL Implementation
The Commonwealth intends for this TMDL to be implemented through best management
practices (BMPs) in the watershed. Implementation will occur in stages. The benefits of
staged implementation are: 1) as stream monitoring continues to occur, it allows for water
quality improvements to be recorded as they are being achieved; 2) it provides a measure
of quality control, given the uncertainties that exist in any model; 3) it provides a
mechanism for developing public support; 4) it helps to ensure the most cost effective
practices are implemented initially, and 5) it allows for the evaluation of the TMDL's
adequacy in achieving the water quality standard. Table E-4 provides load reduction
targets for staged implementation achieving a 10% instantaneous standard violation
reduction for each TMDL watershed.
While section 303(d) of the Clean Water Act and current EPA regulations do not require
the development of TMDL implementation plans as part of the TMDL process, they do
require reasonable assurance that the load and wasteload allocations can and will be
implemented. Additionally, Virginia's 1997 Water Quality Monitoring Information and
Restoration Act (the "Act") directs the State Water Control Board to "develop and
implement a plan to achieve fully supporting status for impaired waters" (Section 62. 1 -
Executive Summary E-8
44.19.7). The Act also establishes that the implementation plan shall include the date of
expected achievement of water quality objectives, measurable goals, corrective actions
necessary and the associated costs, benefits and environmental impacts of addressing the
impairments. EPA outlines the minimum elements of an approvable implementation plan
in its 1999 "Guidance for Water Quality -Based Decisions: The TMDL Process." The
listed elements include implementation actions/management measures, timelines, legal or
regulatory controls, time required to attain water quality standards, monitoring plans, and
milestones for attaining water quality standards.
Once developed, DEQ intends to incorporate the TMDL implementation plan into the
appropriate Water Quality Management Plan (WQMP), in accordance with the Clean
Water Act's Section 303(e). In response to a Memorandum of Understanding (MOU)
between EPA and DEQ, DEQ also submitted a draft Continuous Planning Process to
EPA in which DEQ commits to regularly updating the WQMPs. Thus, the WQMPs will
be, among other things, the repository for all TMDLs and TMDL implementation plans
developed within a river basin.

1. 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.
2. 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.
2. 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.
3. 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.
4. Impaired waters and TMDL limitation. Discharges of stormwater from construction activities to surface
waters identified as impaired in the 2012 § 305(b)/303(d) Water Quality Assessment Integrated
Report or for which a TMDL wasteload allocation has been established and approved prior to the
term of this general permit for (i) sediment or a sediment -related parameter (i.e., total suspended
solids or turbidity) or (ii) nutrients (i.e., nitrogen or phosphorus) are not eligible for coverage under this
general permit unless the operator develops, implements, and maintains a SWPPP that minimizes
the pollutants of concern and, when applicable, is consistent with the assumptions and requirements
of the approved TMDL wasteload allocations. In addition, the operator shall implement the following
items:
General Permit No.: VAR10
Page 2 of 21

9VAC25-880-60 to the VSMP authority after one or more of the following conditions have been met:
General Permit No.: VAR10
Page 4 of 21
a. Necessary permanent control measures included in the SWPPP for the site are in place and
functioning effectively and final stabilization has been achieved on all portions of the site for which
the operator is responsible. When applicable, long term responsibility and maintenance
requirements shall be recorded in the local land records prior to the submission of a notice of
termination;
b. Another operator has assumed control over all areas of the site that have not been finally
stabilized and obtained coverage for the ongoing discharge;
c. Coverage under an alternative VPDES or state permit has been obtained; or
d. For residential construction only, temporary soil stabilization has been completed and the
residence has been transferred to the homeowner.
2. The notice of termination should be submitted no later than 30 days after one of the above conditions
in subdivision 1 of this subsection is met. Authorization to discharge terminates at midnight on the
date that the notice of termination is submitted for the conditions set forth in subdivisions 1 b through
1 d of this subsection. Termination of authorizations to discharge for the conditions set forth in
subdivision 1 a of this subsection shall be effective upon notification from the department that the
provisions of subdivision 1 a of this subsection have been met or 60 days after submittal of the notice
of termination, whichever occurs first.
3. The notice of termination shall be signed in accordance with Part III K of this general permit.
G. Water quality protection.
1. The operator must select, install, implement and maintain control measures as identified in the
SWPPP at the construction site that minimize pollutants in the discharge as necessary to ensure that
the operator's discharge does not cause or contribute to an excursion above any applicable water
quality standard.
2. If it is determined by the department that the operator's discharges are causing, have reasonable
potential to cause, or are contributing to an excursion above any applicable water quality standard,
the department, in consultation with the VSMP authority, may take appropriate enforcement action
and require the operator to:
a. Modify or implement additional control measures in accordance with Part II B to adequately
address the identified water quality concerns;
b. Submit valid and verifiable data and information that are representative of ambient conditions and
indicate that the receiving water is attaining water quality standards; or

PART II
STORMWATER POLLUTION PREVENTION PLAN
A stormwater pollution prevention plan (SWPPP) shall be developed prior to the submission of a
registration statement and implemented for the construction activity, including any support activity,
covered by this general permit. SWPPPs shall be prepared in accordance with good engineering
practices. Construction activities that are part of a larger common plan of development or sale and disturb
less than one acre may utilize a SWPPP template provided by the department and need not provide a
separate stormwater management plan if one has been prepared and implemented for the larger
common plan of development or sale.
The SWPPP requirements of this general permit may be fulfilled by incorporating by reference other plans
such as a spill prevention control and countermeasure (SPCC) plan developed for the site under § 311 of
the federal Clean Water Act or best management practices (BMP) programs otherwise required for the
facility provided that the incorporated plan meets or exceeds the SWPPP requirements of Part II A. All
plans incorporated by reference into the SWPPP become enforceable under this general permit. If a plan
incorporated by reference does not contain all of the required elements of the SWPPP, the operator must
develop the missing elements and include them in the SWPPP.
Any operator that was authorized to discharge under the general permit issued in 2009, and that intends
to continue coverage under this general permit, shall update its stormwater pollution prevention plan to
comply with the requirements of this general permit no later than 60 days after the date of coverage under
this general permit.
A. Stormwater pollution prevention plan contents. The SWPPP shall include the following items
1. General information.
a. A signed copy of the registration statement, if required, for coverage under the general VPDES
permit for discharges of stormwater from construction activities;
b. Upon receipt, a copy of the notice of coverage under the general VPDES permit for discharges of
stormwater from construction activities (i.e., notice of coverage letter);
c. Upon receipt, a copy of the general VPDES permit for discharges of stormwater from construction
activities;
d. A narrative description of the nature of the construction activity, including the function of the
project (e.g., low density residential, shopping mall, highway, etc.);
e. A legible site plan identifying:
(1) Directions of stormwater flow and approximate slopes anticipated after major grading
activities;
(2) Limits of land disturbance including steep slopes and natural buffers around surface waters
that will not be disturbed;
(3) Locations of major structural and nonstructural control measures, including sediment basins
and traps, perimeter dikes, sediment barriers, and other measures intended to filter, settle, or
similarly treat sediment, that will be installed between disturbed areas and the undisturbed
vegetated areas in order to increase sediment removal and maximize stormwater infiltration;
(4) Locations of surface waters;
General Permit No.: VAR10
Page 6 of 21

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:
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
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
General Permit No.: VAR10
Page 18 of 21
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 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.
General Permit No.: VAR10
Page 19 of 21
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 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.
General Permit No.: VAR10
Page 20 of 21
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;
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.
General Permit No.: VAR10
Page 21 of 21
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
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.
Section 12. Inspection logs
INSPECTION FREQUENCY:
(1) Inspections shall be conducted at a frequency of (i) at least once every four business days or (ii) at
least once every five business days and no later than 48 hours following a measurable storm event. In
the event that a measurable storm event occurs when there are more than 48 hours between business
days, the inspection shall be conducted on the next business day; and
(2) Representative inspections used by utility line installation, pipeline construction, or other similar
linear construction activities shall inspect all outfalls discharging to surface waters identified as impaired
or for which a TMDL wasteload allocation has been established and approved prior to the term of this
general permit.
