stormwater management infrastructure including a culvert and manhole, and the removal and replacement of
existing lighting and signage along the runways. A retaining wall and upgraded stormwater routing is also included
with this project. The project will be completed in phases. The expansion of the economy lot and the expansion of
the parking apron will be the two phase to be completed. The relocation of Taxiway E will be the third phase and
will begin after phase two. The electrical and signage improvements along the runways is the fourth phase and will
be completed after phase three has reached stabilization.
The project will have a total disturbed area of approximately 14.21 acres, with no more than 5.72 acres disturbed at
once. Within the limits of the disturbance, there are 11.92 acres of managed turf and 2.29 acres of impervious area
in the current conditions. The total proposed post -development will consist of 8.98 acres of managed turf and 5.23
acres of impervious area.
The project is anticipated to begin in Fall of 2019 and be completed in July of 2021. The project will require a
Virginia Stormwater Management Program Construction General Permit though Albemarle County.

STORMWATER FROM CONSTRUCTION ACTIVITIES
AUTHORIZATION TO DISCHARGE UNDER THE VIRGINIA STORMWATER MANAGEMENT
PROGRAM AND THE VIRGINIA STORMWATER MANAGEMENT ACT
In compliance with the provisions of the Clean Water Act, as amended, and pursuant to the
Virginia Stormwater Management Act and regulations adopted pursuant thereto, operators of
construction activities are authorized to discharge to surface waters within the boundaries of the
Commonwealth of Virginia, except those specifically named in State Water Control Board
regulations that prohibit such discharges.
The authorized discharge shall be in accordance with the registration statement filed with the
Department of Environmental Quality, this cover page, Part I - Discharge Authorization and
Special Conditions, Part II - Stormwater Pollution Prevention Plan, and Part III - Conditions
Applicable to All VPDES Permits as set forth in this general permit.
Construction General Permit
Effective July 1, 2019

DISCHARGE AUTHORIZATION AND SPECIAL CONDITIONS
A. Coverage under this general permit.
During the period beginning with the date of coverage under this general permit and lasting
until the general permit's expiration date, the operator is authorized to discharge stormwater
from construction activities.
This general permit also authorizes stormwater discharges from support activities (e.g.,
concrete or asphalt batch plants, equipment staging yards, material storage areas, excavated
material disposal areas, borrow areas) located on -site or off -site provided that:
a. The support activity is directly related to the construction activity that is required to have
general permit coverage for discharges of stormwater from construction activities;
b. The support activity is not a commercial operation, nor does it serve multiple unrelated
construction activities by different operators;
c. The support activity does not operate beyond the completion of the last construction
activity it supports;
d. The support activity is identified in the registration statement at the time of general permit
coverage;
e. Appropriate control measures are identified in a stormwater pollution prevention plan and
implemented to address the discharges from the support activity areas; and
f. All applicable state, federal, and local approvals are obtained for the support activity.
B. Limitations on coverage.
1. Post -construction discharges. This general permit does not authorize stormwater discharges
that originate from the site after construction activities have been completed and the site,
including any support activity sites covered under the general permit registration, has
undergone final stabilization. Post -construction industrial stormwater discharges may need to
be covered by a separate VPDES permit.
Discharges mixed with nonstormwater. This general permit does not authorize discharges that
are mixed with sources of nonstormwater, other than those discharges that are identified in
Part I E (Authorized nonstormwater discharges) and are in compliance with this general
permit.
Discharges covered by another state permit. This general permit does not authorize
discharges of stormwater from construction activities that have been covered under an
individual permit or required to obtain coverage under an alternative general permit.
Page 3 of 26
4. Impaired waters and total maximum daily load (TMDL) limitation.
Nutrient and sediment impaired waters. Discharges of stormwater from construction
activities to surface waters identified as impaired in the 2016 § 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 stormwater
pollution prevention plan (SWPPP) in accordance with Part II B 5 of this permit that
minimizes the pollutants of concern and, when applicable, is consistent with the
assumptions and requirements of the approved TMDL wasteload allocations and
implements an inspection frequency consistent with Part II G 2 a.
Polychlorinated biphenyl (PCB) impaired waters. Discharges of stormwater from
construction activities that include the demolition of any structure with at least 10,000
square feet of floor space built or renovated before January 1, 1980, to surface waters
identified as impaired in the 2016 § 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 PCB are not eligible for coverage
under this general permit unless the operator develops, implements, and maintains a
SWPPP in accordance with Part II B 6 of this permit that minimizes the pollutants of
concern and, when applicable, is consistent with the assumptions and requirements
of the approved TMDL wasteload allocations, and implements an inspection frequency
consistent with Part II G 2 a.

a separate state or VPDES permit may be commingled with discharges authorized by this general
permit so long as all such discharges comply with all applicable state and VPDES permit
requirements.
D. Prohibition of nonstormwater discharges. Except as provided in Parts I A 2, 1 C, and I E, all
discharges covered by this general permit shall be composed entirely of stormwater associated
with construction activities. All other discharges including the following are prohibited:
1. Wastewater from washout of concrete;
2. Wastewater from the washout and cleanout of stucco, paint, form release oils, curing
compounds, and other construction materials;
Page 4 of 26
3. Fuels, oils, or other pollutants used in vehicle and equipment operation and maintenance;
4. Oils, toxic substances, or hazardous substances from spills or other releases; and
5. Soaps, solvents, or detergents used in equipment and vehicle washing.
E. Authorized nonstormwater discharges. The following nonstormwater discharges from
construction activities are authorized by this general permit when discharged in compliance with
this general permit:
1. Discharges from firefighting activities;
2. Fire hydrant flushings;
3. Waters used to wash vehicles or equipment where soaps, solvents, or detergents have not
been used and the wash water has been filtered, settled, or similarly treated prior to discharge;
4. Water used to control dust that has been filtered, settled, or similarly treated prior to discharge;
5. Potable water sources, including uncontaminated waterline flushings, managed in a manner
to avoid an instream impact;
6. Routine external building wash down where soaps, solvents or detergents have not been used
and the wash water has been filtered, settled, or similarly treated prior to discharge;
7. Pavement wash waters where spills or leaks of toxic or hazardous materials have not occurred
(or where all spilled or leaked material has been removed prior to washing); where soaps,
solvents, or detergents have not been used; and where the wash water has been filtered,
settled, or similarly treated prior to discharge;
8. Uncontaminated air conditioning or compressor condensate;
9. Uncontaminated ground water or spring water;
10. Foundation or footing drains where flows are not contaminated with process materials such

STORMWATER POLLUTION PREVENTION PLAN
A. Stormwater pollution prevent 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 B. 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 shall develop the
missing elements and include them in the SWPPP.
3. Any operator that was authorized to discharge under the general permit effective July 1, 2014,
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.
B. 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:
Page 7 of 26

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