THE EXISTING CONDITIONS WITHIN THE LIMITS OF DISTURBANCE CONSIST OF HEAVY WOODED
VEGETATION ALONG WITH AREAS OF PRESERVED AND MANAGED STEEP SLOPES. STORM
WATER NATURALLY SHEET FLOWS THROUGH THIS VEGETATION AND CONCENTRATES IN
MOORES CREEK. AFTER CONSTRUCTION OF THE BRIDGE, THE TEMPORARY ACCESS ROAD
WILL BE REMOVED, STABILIZED AND VEGETATION WILL NATURALLY TAKE OVER THE PREVIOUS
AREAS OF DISTURBANCE. THE PROPOSED CONDITION WILL MATCH THE EXISTING CONDITION
WHERE STORM WATER SHEET FLOWS THROUGH THE VEGETATION AND CONCENTRATES IN
MOORES CREEK.

Executive Summary
Introduction
The Moore's Creek watershed (VAV-H28R) is a sub -watershed of the Upper Rivanna
River Watershed. The watershed drains 34.92 sq. miles of Albemarle County, Virginia,
including the southern portion of the City of Charlottesville. Moore's Creek flows
approximately 11 miles from its source in the Ragged Mountains to its confluence with
the Rivanna River in Charlottesville. The watershed is predominantly forested, with
residential areas, grasslands, and urban areas the other major land uses.
Water quality sampling on Moore's Creek between August 1991 and January
2002 found that 14.5% of the water samples violated the instantaneous fecal coliform
standard of 1000 cfu1100 ml and that the 30-day geometric mean standard of 200 cfu1100
ml was violated 59% of the time. Due to the high percentages of violations (over 10%)
the stream was placed on Virginia's 1998 303(d) list of impaired waters. A 6.37-mile
reach from the intersection of U.S. Route 29 and County Route 1106 to the confluence of
the Rivanna River was listed as impaired due to elevated levels of fecal coliform bacteria.
In response to the impairment, a Total Maximum Daily Load (TMDL) for fecal
coliform bacteria has been developed for Moore's Creek. The TMDL takes into account
all sources of fecal coliform bacteria, including background sources, considers critical
conditions and seasonal variability, and includes a margin of safety. Incorporation of E.
coli into Virginia's Water Quality Standards, January 2011, Geometric Mean of 126 e. coli
cfu1100 mL, is reflected in the updated TMDL equation and will be updated in permits as
appropriate. Community participation has been encouraged throughout the process.
Details are reviewed below.
Critical Conditions
An analysis of the water quality monitoring record in Moore's Creek shows that
violations of 30-day geometric mean standard occur more than 10% of the time in every
month of the year and that violations of the instantaneous standard have also been
observed in every month of year. Furthermore, violations of the fecal coliform standard
Moore's Creek TMDL x
occur during both dry and wet weather events. Therefore, the critical condition for fecal
coliform bacteria in Moore's Creek is the typical hydrologic year. Special consideration
will be given to the extremes of flow, including periods of very low flows and large
storm events.
Sources and Loading of Fecal Coiiform Bacteria
Fecal coliform bacteria originate from all warm-blooded animals and can
contaminate a stream from point and nonpoint sources. In the Moore's Creek watershed,
fecal coliform bacteria are discharged from two point sources, the Moore's Creek
Advanced Wastewater Treatment Plant, operated by the Rivanna Water and Sewer
Authority, and Southwood Mobile Home park, which operates its own package treatment
plant. The average fecal coliform concentration in the Moore's Creek Plant effluent is 17
cfu1100 ml, and the average volume of outflow is I 1 million gallons per day. This
facility discharges just downstream from the state water quality monitoring site. The
Southwood Mobile Home Park is located along Biscuit Run upstream of the water quality
monitoring site. Poorly treated waste was observed around the outfall from the
Southwood Mobile Home Park plant in February 2002, although there is no record of
chronic permit violations from this plant. The plant has a permit limit of 200 cfu1100 ml
and an average outflow of 39,000 gallons per day. The Virginia Department of
Environmental Quality (VADEQ) water quality monitoring staff is currently
investigating waste solids in the receiving stream near the outfall of Southwood.
VADEQ will manage this problem through compliance assistance or enforcement.
Nonpoint sources include background wildlife, livestock, pets, and humans. Major
wildlife species are deer, geese, raccoons, muskrat, and beaver. Wildlife loads were
applied to both the land surface and as direct input to the stream. Although agriculture is
not intensive in the Moore's Creek watershed, cattle, horses, and goats contributed to the
fecal coliform load to the land. In addition, cattle had access to the stream at two sites,
where direct cattle loads to the stream can occur. Pet loads are dominated by dogs.
Human nonpoint source loads come from failing septic systems, straight pipes to the
stream, and leakage from sanitary sewers. A bacterial source tracking study concluded
that the system was dominated by wildlife impacts, followed by livestock, While human
Moore's Creek TMDL xi
sources did not dominate the samples in the bacterial source tracking study, human
bacteria were consistently detected.
Modeling
The BASINS Nonpoint Source Model (NPSM) and the Hydrologic Simulation Program -
FORTRAN (HSPF) were used to simulate flow and the fate and transport of fecal
coliform bacteria in the Moore's Creek watershed. These models incorporate temporal
and spatial variability within the watershed.
Due to a minimal amount of flow observations from Moore's Creek, an
equivalent watershed approach and synthetic flow generation were used to calibrate the
hydrological component of the models. The Buck Mountain Run watershed within the
Rivanna drainage system was selected as an equivalent watershed. The HSPFINPSM
model was calibrated to the Buck Mountain Run watershed, which is similar although a
bit less developed than the Moore's Creek watershed, for the five-year period between
10/1992-9/1997. A synthetic flow generator that combined an artificial neural network
and a maintenance of variance approach was developed and demonstrated on the Buck
Mountain Run watershed.
The synthetic flow generator was then applied to the Moore's Creek system to
create flow predictions for the period over which significant water quality and flow
observations exist (10/ 1996-8/2001). The synthetic flow predictions not only accurately
reproduced the observed flows on Moore's Creek, but also provided a continuous
calibration target for the NPSMIHSPF model on Moore's Creek. NPSMIHSPF
parameters for the Buck Mountain Run watershed were adjusted to accurately reproduce
the synthetic flows for the 5-year period. The water quality model was then calibrated to
the observed fecal coliform concentrations over the same 5-year period. The fecal
coliform loads that were applied directly to the stream and to the land surface were
calculated on a monthly basis to account for seasonal variability in wildlife populations
and the varying time that cattle will spend in the stream.
Moore's Creek TMDL xii
Results for Existing Conditions
Water quality predictions during the calibration period predicted that under
current conditions the instantaneous standard would be violated 18% of the time and the
30-day geometric mean criterion of 200 cfull00ml would be violated 62.8% of the time.
Of the bacteria that reached the stream, 40.1 % were from wildlife, 34.1 % from livestock,
19.4% from dogs, and 6.4% from human sources, although the relative proportions of
these sources may shin, dependent on whether the stream was at low or high flows and
with season.
Margin of Safety
The fecal coliform load in the TMDL is divided into three categories. One is the
margin of safety (MOS). A margin of safety will be explicitly added by achieving
concentrations 5% below the 30-day geometric mean criterion of 200 cfu1100 ml. The
remaining allowable 190 cfu1100ml is divided between the allowable loading from point
sources (termed the waste load allocation, WLA) and the allowable loading from
nonpoint sources (termed the load allocation, LA).
TMDL Allocation Scenarios
Establishment of a TMDL is meant to provide a loading that will be protective of
water quality in the future. Thus, future conditions were used for determination of the
allowable load. A human population increase and land use changes were assumed,
consistent with the current population growth rate of the county and the county growth
area plan.
For the base case for future land -based nonpoint source loads, the fecal coliform
loading rates (counts/acre/month) for most land uses were held constant with the rates
from the current conditions. The exception was for grasslands, which included pastures.
Due to a rapid decline in livestock populations, the loading rate used for grasslands
during the calibration period was not representative of the anticipated loading in the
future. Therefore, the loading rate for grasslands for the base case was modified to be
consistent with the 2002 population and distribution of livestock within the watershed.
Moore's Creek TMDL xiii
Overall, the grassland loading rates under future conditions averaged 53% of those used
during the calibration period.
For the base case, future loads of coliform bacteria deposited directly in Moore's
Creek will come from four sources: the two point sources and cattle and wildlife in the
stream. Both point sources were modeled as discharging at their maximum permitted
concentration of 200 cfu1100 ml and their expected average outflows. With the increase
in population, the future average outflow from the Moore's Creek wastewater treatment
plant increases to 15 million gallons per day, while the flow volume from Southwood
facility remains unchanged. The direct load from cattle in stream was also reduced due to
loss of livestock from one of the stream access areas. Wildlife deposition directly to the
stream was assumed unchanged from that determined for the present case simulations.
Although some modifications to the wildlife populations and distribution are expected to
be induced by land use alterations, some wildlife populations will decrease while others
will increase. Thus changes in wildlife numbers tend to offset, leaving only a small
impact, relative to the model uncertainty, on the total wildlife load deposited directly in
the stream.
TMDL allocation scenarios were then generated by reducing the base case loads.
The first step in building an allocation scenario was removal of all non -permitted human
bacterial loads (straight pipes, sewer system leakage, and failing septic systems) and
exclusion of cattle from the stream. These changes alone are insufficient to meet the
TMDL goal. However, since untreated human waste should not be reaching the stream
and allowing livestock access to the stream is an inappropriate management practice,
these two steps were assumed in all other scenarios. Furthermore, adding extreme
reductions in the remaining land -based loads from human activities was insufficient to
meet the TMDL target.
Therefore a TMDL allocation that reduced both the direct wildlife loads to stream
and the remaining land -based nonpoint source loads was developed. Reduction levels
varied by subwatershed and by land use. Table 1 shows the recommended load
reductions to meet the TMDL goal. As in previous scenarios, all non -permitted human
sources were removed and cattle were removed from the stream. Some subwatersheds
show zero reductions in one or more of these sources simply because there were no such
Moore's Creek TMDL xiv
sources in the subwatershed under base case conditions. Residential reductions were
assigned to developed subwatersheds along or near the main stem of Moore's Creek.
Reductions in grassland loads were assigned to subwatersheds that still held significant
numbers of livestock. The high percentage reduction to grasslands in subwatershed 9,
assumes that the feral goat population will he removed and hest management practices
will be put in place around the stockyard. For subwatersheds with a significant urban
area, urban contributions were reduced from 45% to 50%, with the highest reductions
assigned to the subwatersheds near the main stem of Moore's Creek.

The corresponding TMDL load allocations for the Moore's Creek watershed are
shown in Table 2. The allocations are based on the total contributions to the stream.
Each point source is allocated its permitted waste load allocation (WLA). The
contribution from the Southwood Mobile Home Park (VA0029955) load, at 200 cfu/100
ml and an average outflow of 39,000 gallons/day, is shown under WLA(SW), while the
contribution from the Moore's Creek Advanced Wastewater Treatment Plant
(VA0025518) load, at 200 cfu1100 ml and an average flow of 15 million gallons per day,
is shown under WLA(MC). These allocations require no reduction from the permitted
point source loads, although any permit violations are assumed eliminated. Table 2 also
Moore's Creek TMDL xv
shows the total allocation to nonpoint sources (ILA) and the load reserved as a margin of
safety (MOS). To meet this TMDL, the required reduction of all nonpoint source
contributions (direct to stream and land based, human controlled and background) is
31.8% compared to current contributions or 34.6% compared to the base case future
contributions. Table 2. was changed to reflect the inclusion of both bacteria Water
Quality Standards (fecal and e. coli), accommodate the preexisting permitted pollutant
waste load allocation, clarify the appropriate temporal units, and delineate and update the
Future Growth.

permitted level. Since the allocation assumes that the point sources are discharging at
their maximum permitted levels, any excess load assigned to the point source takes away
available loading from other sources. Thus, the reductions required from wildlife and the
other nonpoint source land loads may need adjustment as staged implementation occurs
and if monitoring data reflects obtainment of water quality standards.
mplementation and Reasonable Assurance
Section 303(d) of the Clean Water Act does not specify an implementation process for
TMDLs. However, Virginia's 1997 Water Quality Monitoring, Information, and
Restoration Act directs the VADEQ to develop a plan for the expeditious implementation
of TMDLs. VADEQ plans to incorporate TMDL implementation plans as part of the
Moore's Creek TMDL xvi
303(e) Water Quality Management Plans (WQMP). In a recent Memorandum of
Understanding between the VADEQ and U.S. Environmental Protection Agency, the
VADEQ has committed to updating the WQMPs. Thus, the WQMP will serve not only
as a repository of TMDLs, but also maintain a record of the current progress on TMDL
implementation plans. Each implementation plan will contain expected dates of
achievement of water quality objectives, estimated costs, and a description of availability
of funds for implementation of corrective actions.
Implementation of the management plan to meet the TMDL will occur in stages.
A potential Phase 1 goal could be reduction in the violations of the 30-day geometric
mean criterion to less than 1 0% of the time. Removal of all straight pipes and any
episodic permit violations at the Southwood Treatment plant would reduce the violations
of the 30-day geometric mean standard to 5.0% of the time.
Public Participation
A community TMDL advisory committee was convened by the Thomas Jefferson
Planning Disetrict Commission (TJPDC). Ultimately 12 people were named to the
community advisory Committee by the TJPDC, including representatives from Albemarle
County, the City of Charlottesville, the Rivanna Water and Sewer Authority, the Thomas
Jefferson Soil and Water Conservation District, the Albemarle County Farm Bureau, the
Southern Environmental Law Center, the Fry's Springs and Belmont Neighborhood
Associations, and several other interested citizens. The community advisory committee
met on September 21, 2001, November 27, 2001, February 12, 2002, and March 26,
2002. The advisory committee reviewed and provided feedback on the preliminary
loading assumptions and on the final TMDL draft report. Their suggestions were
incorporated into the loading assumptions during the calibration of the water quality
model and into the final TMDL report.
In addition, in compliance with the U.S. Environmental Protection Agency
requirement for public participation, three public meetings were organized and conducted
as part of the formal TMDL process. Public meetings were held in Charlottesville on
June 7, 2001, November 15, 2001, and March 25, 2002. The first two meetings
Moore's Creek TMDL xvii
introduced and reviewed the current status of the TMDL development, while the third
meeting presented the draft TMDL report.
Watershed stakeholders will have opportunities to continue to provide input and
participate in the development of implementation plans for the TMDL. Regional and
local offices of the VADEQ and Virginia Department of Conservation and Recreation,
along with other cooperating agencies, will continue to provide support during the plan
development and implementation stages.

prevent contact with stormwater; and (iii) a similarly effective means designed to
prevent discharge of these pollutants);
(4) Minimize the discharge of pollutants from vehicle and equipment washing, wheel wash
water, and other types of washing (e.g., locating activities away from surface waters
and stormwater inlets or conveyance and directing wash waters to sediment basins or
traps, using filtration devices such as filter bags or sand filters, or using similarly
effective controls);
(5) Direct concrete wash water into a leak -proof container or leak -proof settling basin. The
container or basin shall be designed so that no overflows can occur due to inadequate
sizing or precipitation. Hardened concrete wastes shall be removed and disposed of
in a manner consistent with the handling of other construction wastes. Liquid concrete

addressed above;
(9) Minimize the exposure of waste materials to precipitation by closing or covering waste
containers during precipitation events and at the end of the business day, or
implementing other similarly effective practices. Minimization of exposure is not
required in cases where the exposure to precipitation will not result in a discharge of
pollutants; and
f. Describe procedures for providing pollution prevention awareness of all applicable wastes,
including any wash water, disposal practices, and applicable disposal locations of such
wastes, to personnel in order to comply with the conditions of this general permit. The
operator shall implement the procedures described in the SWPPP.

suspended due to continuous frozen ground conditions and stormwater discharges are
unlikely, the inspection frequency described in Part II G 2 a and 2 b may be reduced to
once per month, If weather conditions (such as above freezing temperatures or rain or
snow events) make discharges likely, the operator shall immediately resume the regular
inspection frequency.
d. Except as prohibited in Part II G 2 a (2), representative inspections may be utilized for
utility line installation, pipeline construction, or other similar linear construction activities
provided that:
(1) Temporary or permanent soil stabilization has been installed and vehicle access may
compromise the temporary or permanent soil stabilization and potentially cause
additional land disturbance increasing the potential for erosion;
(2) Inspections occur on the same frequency as other construction activities;
(3) Control measures are inspected along the construction site 0.25 miles above and
below each access point (i.e., where a roadway, undisturbed right-of-way, or other

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:
5. "1 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.
0. 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 9VAC2.5-870-10, 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 Ill U 2 and
3.
l►#21541 MT
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 ill 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.
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 fogs 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:
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 I II 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 34 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.
