Executive Summary
Background
The Hardware River watershed lies within both Albemarle and Fluvanna
Counties and the North Fork Hardware River flows entirely within Albemarle
County. The Hardware River and the North Fork Hardware River both have
bacteria impairments. The Hardware River is a tributary to the Middle James
River (USGS Hydrologic Unit Code 02080203, Middle James - Buffalo), which
flows into the Chesapeake Bay at Hampton Roads harbor in southeast Virginia.
The North Fork Hardware River is a tributary to Hardware River.
Hardware River has been on the 303(d) impaired waters list since 2002;
the North Fork Hardware River has been listed since 2006, and both were most
recently listed in the 2006 303(d) Report on Impaired Waters (VADEQ, 2006).
Water quality samples collected in the impaired reaches during the 2004
Assessment Period yielded impaired results as shown in Table ES. 1. The
interim instantaneous freshwater water quality standard for fecal coliform
specifies that fecal coliform concentration in the stream water should not exceed
400 colony forming units (cfu) per 100 mL; the instantaneous standard for
Escherichia coli specifies that the E. coli concentration should not exceed 235
cfu/100 mL. Due to the frequency of water quality violations at the stations listed
in Table ES. 1, Hardware River and the North Fork Hardware River remained on
Virginia's 2004 303(d) list of impaired water bodies for fecal coliform. These
impaired segments have been assessed as not supporting the Clean Water Act's
Primary Contact Recreational Use Goal.

This document describes the Total Maximum Daily Loads (TMDLs) for
bacteria that were developed for the Hardware and North Fork Hardware
watersheds in order to remedy the bacteria water quality impairments. The
TMDLs were developed for the new water quality standard for bacteria, which
states that the calendar -month geometric mean concentration of E. coli shall not
exceed 126 cfu/100 mL, and that no single sample can exceed a concentration of
235 cfu/100mL. A glossary of terms used in the development of these TMDLs is
listed in Appendix A.
Sources of Bacteria
There are three point sources permitted to discharge bacteria into the
Hardware River; two of these are located on the South Branch of the North Fork
Hardware River and one on an unnamed tributary to the South Fork Hardware
River. The majority of the bacteria load, however, originates from nonpoint
sources. Nonpoint sources of bacteria are often agricultural and include land -
applied animal waste and manure deposited on pastures by livestock. A
significant bacteria load comes from cattle and wildlife directly depositing feces in
streams. Wildlife also contribute to bacteria loadings on all land uses, in
accordance with the habitat range for each species. Non-agricultural nonpoint
sources of bacteria loadings include straight pipes, failing septic systems, and
pet waste. The bacteria load produced in different locations (e.g., confinement,
pasture, forest) was estimated on a monthly basis to account for seasonal
variability in wildlife behavior and livestock production and practices. Livestock
management and production factors, such as the fraction of time cattle spend in
confinement, pastures, or streams; the amount of manure storage; and spreading
schedules for manure application, were also considered on a monthly basis.
These sources of bacteria can be summarized in two ways. First, Table ES. 2
summarizes the bacteria produced in each location (stream, cropland, pasture,
residential, and forest). Land -deposited sources of bacteria then undergo die -off
and must be transported by runoff from rainfall events into the stream. Direct -
deposited sources enter the stream immediately without die -off and without the
need for a rainfall event. The relative contributions given in Tables ES. 3 and 4
reflect the results of modeling (see next section) that takes into account these
varied fate and transport processes and represents the fraction of in -stream
bacteria attributable to each source.

Modeling
The Hydrological Simulation Program — FORTRAN (HSPF) (Bicknell et al.,
2001) was used to simulate the fate and transport of fecal coliform bacteria in the
Hardware River watershed. HSPF is a continuous model that can represent fate
and transport of pollutants on both the land surface and in the stream. As
recommended by VADEQ, water quality modeling was conducted with fecal
coliform inputs, and a translator equation was used to convert the output to E.
coli for the final TMDL. To identify localized sources of fecal coliform within the
watershed, the Hardware River watershed was divided into 36 sub -watersheds
(24 in the Hardware and 12 in the South Fork Hardware) based on homogeneity
of land use, stream network connectivity, and monitoring station locations. The
North Fork Hardware River watershed was likewise divided into 8 sub -
watersheds.
The hydrology component of HSPF was calibrated using flow data from
September 1, 1989 to August 31, 1995; it was validated using data from
September 1, 1997 to August 31, 2001. Initial estimates of hydrologic
parameters were generated according to the guidance in BASINS Technical Note
iv
6 (USEPA, 2000). These parameters were refined during calibration. The
combination of the optimization program PEST and Expert System for the
Calibration of HSPF (HSPEXP) was used to aid calibration, and after the
successful calibration the default calibration criteria in HSPEXP were met for
both the calibration and validation periods.
The water quality component of the HSPF model was calibrated and
validated for Hardware River at a monitoring station near the watershed outlet.
The model was calibrated during the period from 2000 to 2005 and validated
from 1995 to 1998. The North Fork Hardware River was calibrated with data
from one monitoring station within the watershed, from 1995 to 2005. Inputs to
the model included fecal coliform loadings on land and in the stream. A
comparison of simulated and observed fecal coliform loadings in the stream
indicated that the model adequately simulated the fate and transport of fecal
coliform bacteria.
Existing Conditions
Contributions from various sources in the Hardware and the North Fork
Hardware River watersheds were represented in HSPF to establish the existing
conditions for a representative 3-year period that included both low and high -flow
conditions. Monthly bacteria loadings to different land use categories were
calculated for each sub -watershed. Direct seasonal bacteria loadings to streams
by cattle were calculated for pastures adjacent to streams. Bacteria loadings to
streams and land by wildlife were estimated for several species. Bacteria
loadings to land from failing septic systems were estimated based on information
on failing septic systems from the Virginia Department of Health; contributions of
bacteria directly to the stream from straight pipes were also estimated based on
information from the 2000 Census data, as well as information from other local
sources. Bacteria contributions from pet waste were also considered.
Meteorological data from 1989-2005 were paired with bacterial loading and land
use data for existing conditions to establish this baseline scenario. Results from
the calibrated HSPF model showed routine high signatures from livestock direct
deposit, wildlife direct deposit, and pervious land surfaces.
v
Allocation Scenarios
Different source reduction scenarios were evaluated to identify scenarios
that meet both the calendar -month geometric mean E. coli criterion (126 cfu/100
mL) and the single sample maximum E. coli criterion (235 cfu/100 mL) with zero
violations. These scenarios were conducted using meteorological data from
1996-1998 to represent a variety of high and low flow conditions. The reductions
required for each impaired segment are presented in Table ES. 5 and Table ES.
6. Details on the loads to be reduced from each source are given in Table ES. 7

For North Fork Hardware River, there are two permitted point sources
discharging at or below their permit requirements. For Hardware River, there is
one single family home permitted point source discharging into an unnamed
tributary of the South Fork Hardware River. Therefore, the proposed scenario
requires load reductions only for nonpoint sources of fecal coliform. The TMDL
was determined as the average annual E. coli load at the watershed outlet for the
chosen allocation scenarios. The WLAs for the North Fork Hardware River and
Hardware River watersheds were obtained by taking the product of the permitted
point sources' E. coli discharge concentrations and allowable annual discharges
plus 1 % of the total TMDL load for future growth. The LA was then determined as
the TMDL-WLA. Equation ES.1 was used to calculate the TMDL allocation
shown in Table ES. 11.
TMDL = 7-WLA + FLA + MOS [ES.1]
where:
WLA = wasteload allocation (point source contributions);
LA = load allocation (nonpoint source contributions); and
MOS = margin of safety.

Transitional Scenario
The implementation of a transitional scenario, or staged implementation,
will allow for an evaluation of the effectiveness of management practices and
accuracy of model assumptions through data collection. Staged implementation
was developed without reductions for wildlife; a target of a 10.5% violation rate of
W
the single sample maximum E. coli water quality criterion (235 cfu/100 mL) was
used where the elimination of wildlife reductions did not prohibit it. A staged
scenario for each impaired segment is presented in Tables ES. 12 and 13.

Implementation
The goal of the TMDL program is to establish a three -step path that will
lead to attainment of water quality standards. The first step in the process is to
develop TMDLs that will result in attainment of water quality standards. This
report represents the culmination of that effort for the bacteria impairment on
Hardware River and North Fork Hardware River. The second step is to develop
a TMDL implementation plan. The final step is to implement the TMDL
implementation plan and to monitor stream water quality to determine if water
quality standards are being attained.
Watershed stakeholders will have opportunities to provide input and to
participate in the development of the implementation plan, which will also be
supported by regional and local offices of VADEQ, VADCR, and other
cooperating agencies.

the inspection is complete.
6. 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.
2. 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

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
8. 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.
1. 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 II I 1 1 or 2 in
writing as part of the SWPPP. The reports shall contain the information listed in Part 111 12.
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:
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.
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 I I I 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.
2. As an alternative to transfers under Part III Y 1, this state permit may be automatically
transferred to a new operator if:
a. The current operator notifies the department at least 30 days in advance of the proposed
transfer of the title to the facility or property;
b. The notice includes a written agreement between the existing and new operators
containing a specific date for transfer of state permit responsibility, coverage, and liability
between them; and
c. The department does not notify the existing operator and the proposed new operator of
its intent to modify or revoke and reissue the state permit. If this notice is not received, the
transfer is effective on the date specified in the agreement mentioned in Part III Y 2 b.
3. For ongoing construction activity involving a change of operator, the new operator shall accept
and maintain the existing SWPPP, or prepare and implement a new SWPPP prior to taking
over operations at the site.
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 24 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 as authorized in Part II G 2 d shall not be allowed.
