Section 3. Nature of activity
(Provide a detailed narrative of the construction activities. Include or reference a construction schedule and
sequence. Include any phasing.)
The proposed project consists of removing a legacy earthen dam historically used as a recreational pond, restoring
and enhancing portions of an unnamed perennial tributary to Mechums River and creation of emergent riparian
wetlands around the restored channel. This project is being conducted as a agricultural activitiy. A pre-construction
meeting will be held with the contractor(once selected)to discuss the responsibilities and details of the SWPPP,
including site-specific training. Erosion and sediment control measures will be installed prior to construction. Stream
work will be stabilized at the end of each work day. All exposed areas will be stabilized with seed mix and topsoil
once final grade is met. Once approved from County inspector, all erosion and sediment control measures will be
removed. All construction will be completed in one phase.
SEQUENCE OF CONSTRUCTION
1. Construction Access & ESC
a. Arborist to select remove trees (no stump removal)to minimize disturbance. Contractor to coordinate with
arborist(N.I.C.)on hardwood tree removal and save 10'-20' section
of tree for instream structure and pond habitat placement
b. Construct Temporary Stream Crossing at beginning of project. Construct Construction Entrance (CE) and mulch
haul/access road per plans and install perimeter
controls. Remove tree limbs and vegetation less than 12" dbh as necessary
2. Dewatering/Demo
a. Clear trees in coordination with arborist(no stump removal) as necessary for equipment access. Hardwood trees
to be stockpiled and sufficient 10'-20' material to be used for
instream structure and pond habitat placement.
b. Install diversion outlet from existing concrete dam. Notch concrete or pump to dewater to elevation 464. Ensure
water is discharged to dewatering structure. Establish pump
around as shown on plans. Discharge to filter bag or approved sediment trap downstream of construction. Pump
around is to move downstream with construction.
c. Remove concrete wall and concrete/earthen dam as shown on plans
3. Floodplain Grading
a. Remove material to finished grade and install Sump Pits as necessary to dewater for material removal
b. Compact or import material and mix in pond bottom material at final grade
c. Material to be stockpiled and ultimately spread in the location of the borrow area
4. Stream Restoration
a. Grade restored stream channel from upstream to downstream as shown on plans and install temporary stream
crossing log riffle structures, cascade, and stone step
structures as shown on plans. Stream should be stabilized with matting at the end of each day. Material for fill
should be borrowed from the designated field borrow area.
b. Remove or move temporary stream crossing as necessary during construction.
c. Bedrock has been identified in the area of the spillway/cascade step-pool. Field changes to grades may be
required in this section during construction to utilize bedrock grade
control where possible to enhance natural aesthetic and functioning
d. Once stream has been constructed and stabilized, complete the removal of the concrete dam while dewatering to
Riprap and Temporary Stone Outlet Structure
5. Final Stabilization
d. Install large woody debris in riparian wetland per Landscape Architect's instruction
e. Re-excavate pool as necessary
f. Install plantings and temporary/permanent seeding as specified
g. Remove construction access road and silt fence (other than in area of borrow area) and stabilize to original grade
h. Remove stream crossing bridge
i. Stabilize remaining areas as necessary

DEPARTMENT OF ENVIRONMENTAL QUALITY
General Permit No.: VAR10
Effective Date: July 1, 2014
Expiration Date: June 30, 2019
GENERAL VPDES PERMIT FOR DISCHARGES OF STORMWATER FROM CONSTRUCTION
ACTIVITIES
AUTHORIZATION TO DISCHARGE UNDER THE VIRGINIA STORMWATER MANAGEMENT
PROGRAM AND THE VIRGINIA STORMWATER MANAGEMENT ACT
In compliance with the provisions of the Clean Water Act, as amended, and pursuant to the Virginia
Stormwater Management Act and regulations adopted pursuant thereto, operators of construction
activities are authorized to discharge to surface waters within the boundaries of the Commonwealth of
Virginia, except those specifically named in State Water Control Board regulations that prohibit such
discharges.
The authorized discharge shall be in accordance with this cover page, Part I - Discharge Authorization
and Special Conditions, Part li - Stormwater Pollution Prevention Plan, and Part III - Conditions
Applicable to All VPDES Permits as set forth herein.
General Permit No.: VAR10
Page 1 of 23
PART I
DISCHARGE AUTHORIZATION AND SPECIAL CONDITIONS
A. Coverage under this general permit.
1. During the period beginning with the date of coverage under this general permit and lasting until the
general permit's expiration date, the operator is authorized to discharge stormwater from construction
activities.
2. This general permit also authorizes stormwater discharges from support activities (e.g., concrete or
asphalt batch plants, equipment staging yards, material storage areas, excavated material disposal
areas, borrow areas) located on-site or off-site provided that:
a. The support activity is directly related to the construction activity that is required to have general
permit coverage for discharges of stormwater from construction activities;
b. The support activity is not a commercial operation, nor does it serve multiple unrelated
construction activities by different operators;
c. The support activity does not operate beyond the completion of the last construction activity it
supports;
d. The support activity is identified in the registration statement at the time of general permit
coverage;
e. Appropriate control measures are identified in a stormwater pollution prevention plan and
implemented to address the discharges from the support activity areas; and
f. All applicable state, federal, and local approvals are obtained for the support activity.
B. Limitations on coverage.
1. Post-construction discharges. This general permit does not authorize stormwater discharges that
originate from the site after construction activities have been completed and the site, including any
support activity sites covered under the general permit registration, has undergone final stabilization.
Post-construction industrial stormwater discharges may need to be covered by a separate VPDES
permit.
2. Discharges mixed with nonstormwater. This general permit does not authorize discharges that are
mixed with sources of nonstormwater, other than those discharges that are identified in Part I E
(Authorized nonstormwater discharges) and are in compliance with this general permit.
3. Discharges covered by another state permit. This general permit does not authorize discharges of
stormwater from construction activities that have been covered under an individual permit or required
to obtain coverage under an alternative general permit.
4. Impaired waters and TMDL limitation. Discharges of stormwater from construction activities to surface

less than one acre may utilize a SWPPP template provided by the department and need not provide a
separate stormwater management plan if one has been prepared and implemented for the larger
common plan of development or sale.
The SWPPP requirements of this general permit may be fulfilled by incorporating by reference other plans
such as a spill prevention control and countermeasure (SPCC) plan developed for the site under§ 311 of
the federal Clean Water Act or best management practices (BMP) programs otherwise required for the
facility provided that the incorporated plan meets or exceeds the SWPPP requirements of Part II A. All
plans incorporated by reference into the SWPPP become enforceable under this general permit. If a plan
incorporated by reference does not contain all of the required elements of the SWPPP, the operator must
develop the missing elements and include them in the SWPPP.
Any operator that was authorized to discharge under the general permit issued in 2009, and that intends
to continue coverage under this general permit, shall update its stormwater pollution prevention plan to
comply with the requirements of this general permit no later than 60 days after the date of coverage under
this general permit.

stormwater from construction activities (i.e., notice of coverage letter);
c. Upon receipt, a copy of the general VPDES permit for discharges of stormwater from construction
activities;
d. A narrative description of the nature of the construction activity, including the function of the
project(e.g., low density residential, shopping mall, highway, etc.);
e. A legible site plan identifying:
(1) Directions of stormwater flow and approximate slopes anticipated after major grading
activities;
(2) Limits of land disturbance including steep slopes and natural buffers around surface waters
that will not be disturbed;
(3) Locations of major structural and nonstructural control measures, including sediment basins
and traps, perimeter dikes, sediment barriers, and other measures intended to filter, settle, or
similarly treat sediment, that will be installed between disturbed areas and the undisturbed
vegetated areas in order to increase sediment removal and maximize stormwater infiltration;
(4) Locations of surface waters;
General Permit No.: VAR10
Page 6 of 23

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 modifying, revoking and reissuing, or
terminating this general permit 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;
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

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 herein, 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 but are not limited to 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;
b. The period of noncompliance, including exact dates and times, and if the noncompliance has not
been corrected, the anticipated time it is expected to continue; and
c. Steps taken or planned to reduce, eliminate, and prevent reoccurrence of the noncompliance.
The department may waive the written report on a case-by-case basis for reports of noncompliance
under Part III I if the oral report has been received within 24 hours and no adverse impact on surface
waters has been reported.
3. The operator shall report all instances of noncompliance not reported under Part III 11 or 2 in writing
as part of the SWPPP. The reports shall contain the information listed in Part III 12.
NOTE: The reports required in Part III G, H and I shall be made to the department and the VSMP

Page 17 of 23
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 manager is authorized to make
management decisions that govern the operation of the regulated facility including having the
explicit or implicit duty of making major capital investment recommendations, and initiating and
directing other comprehensive measures to assure long-term compliance with environmental laws
and regulations; the manager can ensure that the necessary systems are established or actions
taken to gather complete and accurate information for state permit application requirements; and
where authority to sign documents has been assigned or delegated to the manager in
accordance with corporate procedures;
b. For a partnership or sole proprietorship: by a general partner or the proprietor, respectively; or
c. For a municipality, state, federal, or other public agency: by either a principal executive officer or
ranking elected official. For purposes of this chapter, a principal executive officer of a public
agency includes: (i) the chief executive officer of the agency or (ii) a senior executive officer
having responsibility for the overall operations of a principal geographic unit of the agency.
2. Reports, etc. All reports required by this general permit, including SWPPPs, and other information
requested by the board or the department shall be signed by a person described in Part Ill K 1 or by a
duly authorized representative of that person. A person is a duly authorized representative only if:
a. The authorization is made in writing by a person described in Part III K 1;
b. The authorization specifies either an individual or a position having responsibility for the overall
operation of the regulated facility or activity such as the position of plant manager, operator of a
well or a well field, superintendent, position of equivalent responsibility, or an individual or position
having overall responsibility for environmental matters for the operator. (A duly authorized
General Permit No.: VAR10
Page 18 of 23
representative may thus be either a named individual or any individual occupying a named
position); and
c. The signed and dated written authorization is included in the SWPPP. A copy must be provided to
the department and VSMP authority, if requested.
3. Changes to authorization. If an authorization under Part III K 2 is no longer accurate because a
different individual or position has responsibility for the overall operation of the construction activity, a
new authorization satisfying the requirements of Part III K 2 shall be submitted to the VSMP authority
as the administering entity for the board prior to or together with any reports or information to be
signed by an authorized representative.
4. Certification. Any person signing a document under Part III K 1 or 2 shall make the following
certification:
"I certify under penalty of law that I have read and understand this document and that this document
and all attachments were prepared in accordance with a system designed to assure that qualified
personnel properly gathered and evaluated the information submitted. Based on my inquiry of the
person or persons who manage the system, or those persons directly responsible for gathering the
information, the information submitted is, to the best of my knowledge and belief, true, accurate, and
complete. I am aware that there are significant penalties for submitting false information, including the
possibility of fine and imprisonment for knowing violations."
L. Duty to comply. The operator shall comply with all conditions of this general permit. Any state permit
noncompliance constitutes a violation of the Virginia Stormwater Management Act and the Clean Water
Act, except that noncompliance with certain provisions of this general permit may constitute a violation of
the Virginia Stormwater Management Act but not the Clean Water Act. Permit noncompliance is grounds
for enforcement action; for state permit termination, revocation and reissuance, or modification; or denial
of a state permit renewal application.
The operator shall comply with effluent standards or prohibitions established under § 307(a) of the Clean
Water Act for toxic pollutants within the time provided in the regulations that establish these standards or
prohibitions or standards for sewage sludge use or disposal, even if this general permit has not yet been
modified to incorporate the requirement.
M. Duty to reapply. If the operator wishes to continue an activity regulated by this general permit after the
expiration date of this general permit, the operator shall submit a new registration statement at least 90
days before the expiration date of the existing general permit, unless permission for a later date has been
granted by the board. The board shall not grant permission for registration statements to be submitted
later than the expiration date of the existing general permit.
N. Effect of a state permit. This general permit does not convey any property rights in either real or
personal property or any exclusive privileges, nor does it authorize any injury to private property or
invasion of personal rights, or any infringement of federal, state or local law or regulations.
O. State law. Nothing in this general permit shall be construed to preclude the institution of any legal
action under, or relieve the operator from any responsibilities, liabilities, or penalties established pursuant
to any other state law or regulation or under authority preserved by § 510 of the Clean Water Act. Except
as provided in general permit conditions on "bypassing" (Part III U) and "upset" (Part III V), nothing in this
general permit shall be construed to relieve the operator from civil and criminal penalties for
noncompliance.
P. Oil and hazardous substance liability. Nothing in this general permit shall be construed to preclude the
institution of any legal action or relieve the operator from any responsibilities, liabilities, or penalties to
which the operator is or may be subject under§§ 62.1-44.34:14 through 62.1-44.34:23 of the State Water
Control Law or§ 311 of the Clean Water Act.
General Permit No.: VAR10
Page 19 of 23
Q. Proper operation and maintenance. The operator shall at all times properly operate and maintain all
facilities and systems of treatment and control (and related appurtenances), which are installed or used
by the operator to achieve compliance with the conditions of this general permit. Proper operation and
maintenance also includes effective plant performance, adequate funding, adequate staffing, and
adequate laboratory and process controls, including appropriate quality assurance procedures. This
provision requires the operation of back-up or auxiliary facilities or similar systems, which are installed by
the operator only when the operation is necessary to achieve compliance with the conditions of this
general permit.
R. Disposal of solids or sludges. Solids, sludges or other pollutants removed in the course of treatment or
management of pollutants shall be disposed of in a manner so as to prevent any pollutant from such
materials from entering surface waters and in compliance with all applicable state and federal laws and
regulations.
S. Duty to mitigate. The operator shall take all steps to minimize or prevent any discharge in violation of
this general permit that has a reasonable likelihood of adversely affecting human health or the
environment.
T. Need to halt or reduce activity not a defense. It shall not be a defense for an operator in an
enforcement action that it would have been necessary to halt or reduce the permitted activity in order to
maintain compliance with the conditions of this general permit.
U. Bypass.
1. "Bypass," as defined in 9VAC25-870-10, means the intentional diversion of waste streams from any
portion of a treatment facility. The operator may allow any bypass to occur that does not cause
effluent limitations to be exceeded, but only if it also is for essential maintenance to ensure efficient
operation. These bypasses are not subject to the provisions of Part III U 2 and 3.
2. Notice.
a. Anticipated bypass. If the operator knows in advance of the need for a bypass, the operator shall
submit prior notice to the department, if possible at least 10 days before the date of the bypass.
b. Unanticipated bypass. The operator shall submit notice of an unanticipated bypass as required in
Part III I.
3. Prohibition of bypass.
a. Except as provided in Part III U 1, bypass is prohibited, and the board or department may take
enforcement action against an operator for bypass unless:
(1) Bypass was unavoidable to prevent loss of life, personal injury, or severe property damage.
Severe property damage means substantial physical damage to property, damage to the
treatment facilities that causes them to become inoperable, or substantial and permanent
loss of natural resources that can reasonably be expected to occur in the absence of a
bypass. Severe property damage does not mean economic loss caused by delays in
production;
(2) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment
facilities, retention of untreated wastes, or maintenance during normal periods of equipment
downtime. This condition is not satisfied if adequate back-up equipment should have been
installed in the exercise of reasonable engineering judgment to prevent a bypass that
occurred during normal periods of equipment downtime or preventive maintenance; and
(3) The operator submitted notices as required under Part III U 2.
General Permit No.: VAR10
Page 20 of 23
b. The department may approve an anticipated bypass, after considering its adverse effects, if the
department determines that it will meet the three conditions listed in Part III U 3 a.
V. Upset.
1. An "upset," as defined in 9VAC25-870-10, means an exceptional incident in which there is
unintentional and temporary noncompliance with technology-based state permit effluent limitations
because of factors beyond the reasonable control of the operator. An upset does not include
noncompliance to the extent caused by operational error, improperly designed treatment facilities,
inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation.
2. An upset constitutes an affirmative defense to an action brought for noncompliance with technology-
based state permit effluent limitations if the requirements of Part III V 4 are met. A determination
made during administrative review of claims that noncompliance was caused by upset, and before an
action for noncompliance, is not a final administrative action subject to judicial review.
3. An upset does not include noncompliance to the extent caused by operational error, improperly
designed treatment facilities, inadequate treatment facilities, lack of preventative maintenance, or
careless or improper operation.
4. An operator who wishes to establish the affirmative defense of upset shall demonstrate, through
properly signed, contemporaneous operating logs or other relevant evidence that:
a. An upset occurred and that the operator can identify the cause(s) of the upset;
b. The permitted facility was at the time being properly operated;
c. The operator submitted notice of the upset as required in Part III I; and
d. The operator complied with any remedial measures required under Part III S.
5. In any enforcement proceeding, the operator seeking to establish the occurrence of an upset has the
burden of proof.
W. Inspection and entry. The operator shall allow the department as the board's designee, the VSMP
authority, EPA, or an authorized representative of either entity (including an authorized contractor), upon
presentation of credentials and other documents as may be required by law to:
1. Enter upon the operator's premises where a regulated facility or activity is located or conducted, or
where records must be kept under the conditions of this general permit;
2. Have access to and copy, at reasonable times, any records that must be kept under the conditions of
this general permit;
3. Inspect and photograph at reasonable times any facilities, equipment (including monitoring and
control equipment), practices, or operations regulated or required under this general permit; and
4. Sample or monitor at reasonable times, for the purposes of ensuring state permit compliance or as
otherwise authorized by the Clean Water Act or the Virginia Stormwater Management Act, any
substances or parameters at any location.
For purposes of this section, the time for inspection shall be deemed reasonable during regular business
hours, and whenever the facility is discharging. Nothing contained herein shall make an inspection
unreasonable during an emergency.
General Permit No.: VAR10
Page 21 of 23
X. State permit actions. State permits may be modified, revoked and reissued, or terminated for cause.
The filing of a request by the operator for a state permit modification, revocation and reissuance, or
termination, or a notification of planned changes or anticipated noncompliance does not stay any state
permit condition.
Y. Transfer of state permits.
1. State permits are not transferable to any person except after notice to the department. Except as
provided in Part III Y 2, a state permit may be transferred by the operator to a new operator only if the
state permit has been modified or revoked and reissued, or a minor modification made, to identify the
new operator and incorporate such other requirements as may be necessary under the Virginia
Stormwater Management Act and the Clean Water Act.
2. As an alternative to transfers under Part III Y 1, this state permit may be automatically transferred to a
new operator if:
a. The current operator notifies the department at least 30 days in advance of the proposed transfer
of the title to the facility or property;
b. The notice includes a written agreement between the existing and new operators containing 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.
General Permit No.: VAR10

DEFINITIONS
"Business day" means Monday through Friday excluding state holidays.
"Commencement of land disturbance" means the initial disturbance of soils associated with clearing,
grading, or excavating activities or other construction activities (e.g., stockpiling of fill material).
"Construction site" means the land where any land-disturbing activity is physically located or conducted,
including any adjacent land used or preserved in connection with the land-disturbing activity.
"Final stabilization" means that one of the following situations has occurred:
1. All soil disturbing activities at the site have been completed and a permanent vegetative cover has

Section 12. Inspection logs
(Provide templates for your inspections. Requirements are listed in 9VAC25-880-70, Part II, section B and F.)
Issued— 10/2014 Stormwater Pollution Prevention Plan(SWPPP)Albemarle County
Inspection Report Template - Field Version
Purpose
This Inspection Report Template (or "template") was designed to assist you in preparing inspection reports for
EPA's 2012 Construction General Permit (CGP). If you are covered under the 2012 CGP, this template will
enable you to create an inspection report form that is customized to the specific circumstances of your project
and that complies with the minimum reporting requirements of Part 4.1.7 of the permit. Note that the use of this
form is optional;you may use your own inspection report form provided it includes the minimum information
required in Part 4.1.7 of the CGP.
If you are covered under a state CGP, this template may be helpful in developing a form that can be used for
that permit; however it will need to be modified to meet the specific requirements of that permit. If your
permitting authority requires you to use a specific inspection report form,you should not use this form.
Notes:
While EPA has made every effort to ensure the accuracy of all instructions and guidance contained in the
Inspection Report Template, the actual obligations of regulated construction activities are determined by the
relevant provisions of the permit, not by the template. In the event of a conflict between the Inspection Report
Template and any corresponding provision of the 2012 CGP, you must abide by the requirements in the permit.
EPA welcomes comments on the Inspection Report Template at any time and will consider those comments in
any future revision of this document.You may contact EPA for CGP-related inquiries at cgp@epa.caov.
Overview of Inspection Requirements
Construction operators covered under the 2012 CGP are subject to the following requirements in Part 4:
Inspection Frequency(see Part 4.1.4)
You are required to conduct inspections either:
• Once every 4 business days;or
• Once every 5 business days and within 48 hours of a storm event of 0.25 inches or greater.
Your inspection frequency is increased if the site discharges to a sensitive water.See Part 4.1.3.Your inspection
frequency may be decreased to account for stabilized areas, or for arid,semi-arid,or drought-stricken conditions,or for
frozen conditions.See Part 4.1.4.
Areas That Need to Be Inspected(see Part 4.1.5)
During each inspection,you must inspect the following areas of your site:
• Cleared, graded,or excavated areas of the site;
• Stormwater controls (e.g., perimeter controls, sediment basins, inlets, exit points etc.) and pollution prevention
practices (e.g., pollution prevention practices for vehicle fueling/maintenance and washing, construction product
storage, handling, and disposal,etc.) at the site;
• Material,waste, or borrow areas covered by the permit, and equipment storage and maintenance areas;
• Areas where stormwater flows within the site;
• Stormwater discharge points;and
• Areas where stabilization has been implemented.
What to Check For During Your Inspection (see Part 4.1.6)
During your site inspection,you are required to check:
• Whether stormwater controls or pollution prevention practices require maintenance or corrective action,or whether
new or modified controls are required;
• For the presence of conditions that could lead to spills, leaks, or other pollutant accumulations and discharges;
• Whether there are visible signs of erosion and sediment accumulation at points of discharge and to the channels and
streambanks that are in the immediate vicinity of the discharge;
• If a stormwater discharge is occurring at the time of the inspection,whether there are obvious,visual signs of pollutant
discharges;and
• If any permit violations have occurred on the site.
Inspection Reports (see Part 4.1.7)
Within 24 hours of completing each inspection,you are required to complete an inspection report that includes:
i
• Date of inspection;
• Names and titles of persons conducting the inspection;
• Summary of inspection findings;
• Rain gauge or weather station readings if your inspection is triggered by the 0.25 inch storm threshold; and
• If you determine that a portion of your site is unsafe to access for the inspection, documentation of what conditions
prevented the inspection and where these conditions occurred on the site
Instructions for Using This Template
This Field Version of the Inspection Report Template is intended to be used in the field and filled out by hand. If
you will be filling out the Inspection Report Template electronically (i.e., you will be typing in your findings),
please use the Electronic Version of the Inspection Report Template available at
www.epa.ciov/npdes/stormwater/swppp. The Electronic Version includes text fields with instructions for what to
enter.
Keep in mind that this document is a template and not an "off-the-shelf" inspection report that is ready to use
without some modification. You must first customize this form to include the specifics of your project in order for
it to be useable for your inspection reports. Once you have entered all of your site-specific information into
these fields, you may print out this form for use in the field to complete inspection reports.
The following tips for using this template will help you ensure that the minimum permit requirements are met:
• Review the inspection requirements. Before you start developing your inspection report form, read the
CGP's Part 4 inspection requirements. This will ensure that you have a working understanding of the
permit's underlying inspection requirements.
• Complete all required text fields. Fill out at text fields. Only by filling out all fields will the template be
compliant with the requirements of the permit. (Note: Where you do not need the number of rows
provided in the template form for your inspection, you may leave those rows blank. Or, if you need
more space to document your findings, you may add an additional sheet.)
• Use your site map to document inspection findings. In several places in the template, you are directed
to specify the location of certain features of your site, including where stormwater controls are installed
and where you will be stabilizing exposed soil. You are also asked to fill in location information for unsafe
conditions and the locations of any discharges occurring during your inspections. Where you are asked
for location information, EPA encourages you to reference the point on your SWPPP site map that
corresponds to the requested location on the inspection form. Using the site map as a tool in this way
will help you conduct efficient inspections, will assist you in evaluating problems found, and will ensure
proper documentation.
• Sign and certify each inspection report. Each inspection report must be signed and certified by the
permittee to be considered complete. Where your inspections are carried out by a contractor or
subcontractor, it is recommended that you also have the form signed and certified by the inspector, in
addition to the signature and certification required of the permitted operator. The template includes a
signature block for both parties.
• Include the inspection form with your SWPPP. Once your form is complete, make sure to include a copy
of the inspection form in your SWPPP in accordance with Part 7.2.12.4 of the CGP.
• Retain copies of all inspection reports with your records. You must also retain in your records copies of all
inspection reports in accordance with the requirements in Part 4.1.7.3 of the 2012 CGP.These reports
must be retained for at least 3 years from the date your permit coverage expires or is terminated.

Present Phase of Construction
If this project is being completed in more than one phase,indicate which phase it is currently in.
Inspection Location
If your project has multiple locations where you conduct separate inspections,specify the location where this inspection is being conducted. If only one inspection is
conducted for your entire project,enter"Entire Site." If necessary, complete additional inspection report forms for each separate inspection location.
Inspection Frequency
Check the box that describes the inspection frequency that applies to you. Note that you may be subject to different inspection frequencies in different areas of your
site.If your project does not discharge to a "sensitive water" (i.e., a water impaired for sediment or nutrients, or listed as Tier 2,2.5,or 3 by your state or tribe) and you
are not affected by any of the circumstances described in CGP Part 4.1.4,then you can choose your frequency based on CGP Part 4.1.2—either weekly, or every
other week and within 24 hrs of a 0.25 in storm event. For any portion of your site that discharges to a sensitive water,your inspection frequency for that area is fixed
under CGP Part 4.1.3 at weekly and within 24 hrs of a 0.25 inch storm event. If portions of your site are stabilized, are located in arid,semi-arid,or drought-stricken
areas,or are subject to frozen conditions,consult CGP Part 4.1.4 for the applicable inspection frequency.Check all the inspection frequencies that apply to your
project.
Was This Inspection Triggered by a 0.25 Inch Storm Event?
If you were required to conduct this inspection because of a 0.25 inch (or greater) rain event,indicate whether you relied on an on-site rain gauge or a nearby
weather station (and where the weather station is located).Also,specify the total amount of rainfall for this specific storm event.
Unsafe Conditions for Inspection
Inspections are not required where a portion of the site or the entire site is subject to unsafe conditions.See CGP Part 4.1.5.These conditions should not regularly occur,
and should not be consistently present on a site. Generally, unsafe conditions are those that render the site (or a portion of it) inaccessible or that would pose a
significant probability of injury to applicable personnel. Examples could include severe storm or flood conditions, high winds, and downed electrical wires.
If your site,or a portion of it,is affected by unsafe conditions during the time of your inspection, provide a description of the conditions that prevented you from
conducting the inspection and what parts of the site were affected.If the entire site was considered unsafe, specify the location as "Entire site"

*Note:The permit differentiates between conditions requiring repairs and maintenance,and those requiring corrective action.The permit requires maintenance in
order to keep controls in effective operating condition and requires repairs if controls are not operating as intended.Corrective actions are triggered only for specific,
more serious conditions,which include: 1) A required stormwater control was never installed,was installed incorrectly,or not in accordance with the requirements in
Part 2 and/or 3;2) You become aware that the stormwater controls you have installed and are maintaining are not effective enough for the discharge to meet
applicable water quality standards or applicable requirements in Part 3.1;3) One of the prohibited discharges in Part 2.3.1 is occurring or has occurred;or 4) EPA
requires corrective actions as a result of a permit violation found during an inspection carried out under Part 4.2.If a condition on your site requires a corrective action,
you must also fill out a corrective action form found at www.eoa.gov/nodes/stormwater/swDpp.See Part 5 of the permit for more information.

Instructions for Filling Out the "Erosion and Sediment Control" Table
Type and Location of E&S Controls
Provide a list of all erosion and sediment (E&S) controls that your SWPPP indicates will be installed and implemented at your site.This list must include at a minimum all
E&S controls required by CGP Part 2.1.2. Include also any natural buffers established under CGP Part 2.1.2.1. Buffer requirements apply if your project's earth-disturbing
activities will occur within 50 feet of a surface water.You may group your E&S controls on your form if you have several of the same type of controls (e.g.,you may
group "Inlet Protection Measures", "Perimeter Controls", and "Stockpile Controls" together on one line), but if there are any problems with a specific control,you must
separately identify the location of the control,whether repairs or maintenance or corrective action are necessary,and in the notes section you must describe the
specifics about the problem you observed.
Repairs or Other Maintenance Needed?
Answer"yes" if the E&S control requires a repair of any kind (due to normal wear and tear,or as a result of damage) or requires maintenance in order for the control
to continue operating effectively. At a minimum, maintenance is required in the following specific instances: (1) for perimeter controls,whenever sediment has
accumulated to or more the above-ground height of the control (CGP Part 2.1.2.2.b); (2) where sediment has been tracked-out onto the surface of off-site streets
or other paved areas (CGP Part 2.1.2.3.d); (3) for inlet protection measures,when sediment accumulates,the filter becomes clogged, and/or performance is
compromised (CGP Part 2.1.2.9.b);and (4) for sediment basins,as necessary to maintain at least'A of the design capacity of the basin (CGP Part 2.1.3.2.b). Note: In
many cases, "yes" answers are expected and indicate a project with an active operation and maintenance program.You should also answer"yes" if work to fix the
problem is still ongoing from the previous inspection.
Corrective Action Needed?
Answer"yes"if during your inspection you found any of the following conditions to be present (CGP, Part 5.2.1): (1) a required E&S control was never installed,was
installed incorrectly,or not in accordance with the corresponding CGP Part 2 or 3 requirement; (2) you become aware that the inadequacy of the E&S control has led
to an exceedance of an applicable water quality standard; or (3) EPA requires corrective action for an E&S control as a result of a permit violation found during an
inspection carried out under Part 4.2. If you answer"yes",you must take corrective action and complete a corrective action report,found at
www.eoa.gov/nodes/stormwater/swoop.Note: You should answer"yes"if work to fix the problem from a previous inspection is still ongoing.
Date on Which Maintenance or Corrective Action First Identified?
Provide the date on which the condition that triggered the need for maintenance or corrective action was first identified. If the condition was just discovered during
this inspection,enter the inspection date. If the condition is a carryover from a previous inspection, enter the original date of the condition's discovery.
Notes
For each E&S control and the area immediately surrounding it, note whether the control is properly installed and whether it appears to be working to minimize
sediment discharge. Describe any problem conditions you observed such as the following,and why you think they occurred as well as actions (e.g.,repairs,
maintenance,or corrective action) you will take or have taken to fix the problem:
1.Failure to install or to properly install a required E&S control
2.Damage or destruction to an E&S control caused by vehicles,equipment, or personnel,a storm event,or other event
3.Mud or sediment deposits found downslope from E&S controls
4.Sediment tracked out onto paved areas by vehicles leaving construction site
5.Noticeable erosion at discharge outlets or at adjacent streambanks or channels
6.Erosion of the site's sloped areas (e.g.,formation of rills or gullies)
7.E&S control is no longer working due to lack of maintenance
For buffer areas, make note of whether they are marked off as required,whether there are signs of construction disturbance within the buffer,which is prohibited
under the CGP,and whether there are visible signs of erosion resulting from discharges through the area.
If repairs, maintenance, or corrective action is required, briefly note the reason. If repairs, maintenance, or corrective action have been completed, make a note of
the date it was completed and what was done.If corrective action is required, note that you will need to complete a separate corrective action report describing
the condition and your work to fix the problem.
