Issued — 10/2019 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County
Section 4. Nature of activity
This Re-Developmont project proposes to add eight (8) small "maker space" live/work cottages, renovate a small existing
parking lot, and add two other small parking lots to the 2000/2010 Marchant property. The project site is 2000 Marchant
Street in Charlottesville, Virginia across the street from the historic Woolen Mills site. Despite the Charlottesville address,
there property is Tax Map Parcel number 78-21H0 in Albemarle County. The property acreage is 1.36 acres, and the
development improvements will encroach onto a small, adjacent piece of vacant land that lies between the Marchant
Street right of way and the subject property that is believed to be owned by Virginia Pacific Investments. There will be 1.0
acre of disturbance associated with this project. All the disturbance will occur between Broadway Street, Marchant Street,
and the existing large residential structure on site, which is currently a mix of turf, pavement, and large specimen trees.
The topography steeply rises from the street and then is relatively flat across of the disturbed area. The proposed grading
will closely match the existing topography where possible, to preserve several of these specimen trees.
There will be an increase of impervious area within the limits of disturbance from 10,364 square feet to 19,600 square
feet. Increased storm runoff from this development will be managed through the use of permeable pavement in the
parking areas, a rain garden, and an underground stormwater detention tank which will allow for release of stormwater
back into the existing downstream storm system at acceptable rate.
Site construction will begin in January of 2023 and conclude by the end of December of 2023.
Sequence of Construction
I. Clearly mark limits of work.
2. Establish construction entrance and install culvert inlet protection on existing pipe inlet adjacent to construction
entrance as shown on the plan. Utilize nearby fire hydrant for tire washing.
3. Install perimeter silt fencing, inlet protection, tree protection, and all other perimeter measures as shown on the
plan.
4. Establish staging area and stockpile area as shown on plan.
5. Re-route gas line as shown on the plans. Maintain erosion control at downhill perimeter of utility trench.
6. Once gas utilities are re-routed, install temporary sediment trap and associated diversion dikes.
7. Establish rough grades shown on Stage A ESC Plan and install temporary seeding on all disturbed areas.
8. Construct building pads and continue building construction while maintaining sediment trap.
9. Move to Stage B ESC Plan.
10. While continuing to maintain sediment trap, begin installation of parking lot sub -base, curbing, and trench drains.
II. Maintain sediment trap as long as possible during parking lot construction.
12. As the time nears to remove the sediment trap, stabilize all upstream disturbed areas with turf or gravel, and
contact the County Erosion Control Officer for approval.
13. Identify a likely period of dry weather and decommission the sediment trap accordingly.
14. Install the underground detention system and incoming/outgoing storm structures with inlet and outlet protection.
15. Install all other site plan utilities, sidewalks, parking lots, and drives while maintaining adequate downstream
sediment trapping measures.
16. Once all final grades are reached on non -paved areas begin establishment of vegetation on disturbed areas with
permanent seeding or sodding, mulching, fertilization, and liming. Amend soils where needed. Consult with
Engineer or Landscape Architect before establishing vegetation.
17. Once remainder of site has been deemed stabilized by the county inspector and all construction activities are
completed, restore staging and access areas to acceptable (pre -construction) conditions, install landscape plan
plantings, and remove all other erosion control measures.

STORMTANK INSPECTION AND MAINTENANCE
MAINTENANCE OF PERMEABLE PAVEMENT IS DRIVEN BY ANNUAL INSPECTIONS THAT EVALUATE THE CONDITION AND PERFORMANCE OF
THE PRACTICE.
IT IS HIGHLY RECOMMENDED THAT A SPRING MAINTENANCE INSPECTION AND CLEANUP BE CONDUCTED AT EACH PERMEABLE PAVEMENT
SITE.
THE FOLLOWING ARE SUGGESTED ANNUAL MAINTENANCE INSPECTION POINTS FOR PERMEABLE PAVEMENTS:
• THE DRAWDOWN RATE SHOULD BE MEASURED AT THE OBSERVATION WELL FOR THREE (3) DAYS FOLLOWING A STORM EVENT IN
EXCESS OF 1/2 INCH IN DEPTH. IF STANDING WATER IS STILL OBSERVED IN THE WELL AFTER THREE DAYS, THIS IS A CLEAR SIGN THAT
CLOGGING IS A PROBLEM.
• INSPECT THE SURFACE OF THE PERMEABLE PAVEMENT FOR EVIDENCE OF SEDIMENT DEPOSITION, ORGANIC DEBRIS, STAINING OR
PONDING THAT MAY INDICATE SURFACE CLOGGING. IF ANY SIGNS OF CLOGGING ARE NOTED, SCHEDULE A VACUUM SWEEPER (NO
BROOMS OR WATER SPRAY) TO REMOVE DEPOSITED MATERIAL. THEN, TEST SECTIONS BY POURING WATER FROM A FIVE GALLON
BUCKET TO ENSURE THEY WORK.
• INSPECT THE STRUCTURAL INTEGRITY OF THE PAVEMENT SURFACE, LOOKING FOR SIGNS OF SURFACE DETERIORATION, SUCH AS
SLUMPING, CRACKING. SPAWNG OR BROKEN PAVERS. REPLACE OR REPAIR AFFECTED AREAS, AS NECESSARY.
• CHECK INLETS, PRETREATMENT CELLS AND ANY FLOW DIVERSION STRUCTURES FOR SEDIMENT BUILDUP AND STRUCTURAL DAMAGE.
NOTE IF ANY SEDIMENT NEEDS TO BE REMOVED.
• INSPECT THE CONDITION OF THE OBSERVATION WELL AND MAKE SURE R IS STILL CAPPED.
• GENERALLY INSPECT ANY CONTRIBUTING DRAINAGE AREA FOR ANY CONTROLLABLE SOURCES OF SEDIMENT OR EROSION.

THERE WILL BE A PORTA OHN, A DUMPSTER FOR SOLID WASTES, A FREIGHT CONTAINER FOR STORAGE MATERIALS, AND AN ABOVE GROUND CONCRETE WASH -OUT AREA LOCATED IN THE PROPOSED CONSTRUCTION STAGING AREAAS SHOWN ON THE PLAN. ALL MATERIAL DELIVERY AND STORAGE
SHALL OCCUR IN THE CONSTRUCTION STAGING AREA. ALL VEHICLE, MATERIAL, AND EQUIPMENT WASHING SHALL OCCUR IN THE STAGING AREA OR AT THE WASH RACK. THE CONTRACTOR SHALL ENSURE THAT THE DRAINAGE AREA FROM THESE ACTIVITIES FLOWS TO SEDIMENT TRAPPING DEVICES.
RECEIVING WATERS
RUNOFF FROM THIS SITE DRAINS TO MOORE'S CREEK SEVERAL PARCELS DOWNSTREAM. THE PROPOSED DISTURBED AREA IS SLIGHTLY OVER AN ACRE. INLET PROTECTION ON EXISTING AND PROPOSED SITE DROP INLETS AND SILT FENCE WILL ADEQUATELY PROTECT AGAINST SILTATION
DOWNSTREAM.
THIS SITE HAS BEEN DESIGNED IN ACCORDANCE WITH 4VAC25-870-66. SEE THE WPONSMP PLAN FOR SPECIFICS RELATING TO STORM WATER QUALITY AND QUANTITY COMPLIANCE.
ALL EROSION CONTROL MEASURES ARE TO BE CONSTRUCTED IN ACCORDANCE WITH THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK, THIRD EDITION 1992.
ALL LAND DISTURBING ACTIVITIES SHALL BE IN ACCORDANCE WITH VIRGINIA EROSION AND SEDIMENT CONTROL LAW AND REGULATIONS 4VAC2S840.
EXISTING VEGETATION SHALL BE PRESERVED TO MAXIMUM EXTENT PRACTICAL AND DISTURBED PORTIONS OF THE SITE SHALL BE STABILIZED AS QUICKLY AS POSSIBLE.
IF PERIODIC INSPECTIONS OR OTHER INFORMATION INDICATED THE NEED FOR MODIFYING OR PROVIDING ADDITIONAL EROSION CONTROL MEASURES, THE OPERATOR MUST REPLACE OR MODIFY THE MEASURES AS SOON AS POSSIBLE, AS WELL AS UPDATE THE SWPPP.
ALL CONSTRUCTION MATERIALS AND DEBRIS SHALL BE STORED WITHIN THE LIMITS OF DISTURBANCE.
ANY LITTER EXPOSED TO STORMWATER SHALL BE PREVENTED FROM BECOMING A POLLUTANT SOURCE IN STORMWATER DISCHARGES. THE CONSTRUCTION SITE SHALL BE MONITORED DAILY TO CONTROL LITTER.
TEMPORARY PORTAJOHNS SHALL BE UTILIZED DURING CONSTRUCTION AND SHALL BE LOCATED WITHIN THE DISTURBED AREA.
ALL POLLUTION CONTROL MEASURES SHALL BE PROPERLY MAINTAINED IN AN EFFECTIVE OPERATING CONDITION IN ACCORDANCE WITH GOOD ENGINEERING PRACTICE AND, WHERE APPLICABLE, MANUFACTURER RECOMMENDATIONS. IF SITE INSPECTIONS IDENTIFY CONTROL MEASURES ARE NOT
OPERATING EFFECTIVELY, MAINTENANCE SHALL BE PERFORMED AS SOON AS POSSIBLE TO MAINTAIN CONTINUED EFFECTIVENESS OF THE STORMWATER CONTROLS.
IN THE EVENT THAT ADDITIONAL AREAS ARE BEING UTILIZED FOR CONTAMINATE DISPOSAL, NOT SPECIFICALLY CONTROLLED BY AN APPROVED EROSION CONTROL MEASURE, THE PLAN SHALL BE IMMEDIATELY REVISED TO REFLECTALL CURRENT, POTENTIAL POLLUTANT LOCATIONS, AS WELL AS
SPECIFY ANY ADDITIONAL MEASURES NECESSARY FOR ASSURANCE OF THE PROPER MAINTENANCE AND APPLICABLE SPILL PREVENTION CONTROL.

Pollution Prevention Practices:
(1) Clearing, grading, excavating and un-stabilized areas — Utilize erosion and sediment controls to prevent
sediment laden or turbid runoff from leaving the construction site. Dispose of clearing debris at acceptable
disposal sites. Apply permanent or temporary stabilization, sodding and/or mulching to denuded areas in
accordance with the erosion and sediment control specifications and the general VPDES permit for discharges of
stormwater from construction activities.
(2) Paving operations — Cover storm drain inlets during paving operations and utilize pollution prevention materials
such as drip pans and absorbent/oil dry for all paving machines to limit leaks and spills of paving materials and
fluids.
(3) Concrete washout and cement waste — Direct concrete wash water into a leak -proof container or leak -proof
settling basin that is designed so that no overflows can occur due to inadequate sizing or precipitation. Hardened
concrete wastes shall be removed and disposed of in a manner consistent with the handling of other construction
wastes.
(4) Structure construction, stucco, painting and cleaning — Enclose, cover or berm building material storage areas if
susceptible to contaminated stormwater runoff. Conduct painting operations consistent with local air quality and
OSHA regulations. Mix paint indoors, in a containment area or in a flat unpaved area. Prevent the discharge of
soaps, solvents, detergents and wash water from construction materials, including the clean-up of stucco paint,
form release oils and curing compounds.
(5) Dewatering operations — Construction site dewatering from building footings or other sources may not be
discharged without treatment. Sediment laden or turbid water shall be filtered, settled or similarly treated prior to
discharge.
(6) Material delivery and storage — Designate areas of the construction site for material delivery and storage. Place
near construction entrances, away from waterways, and avoid transport near drainage paths or waterways.
(7) Material use during building process — Use materials only where and when needed to complete the construction
activity. Follow manufacturer's instructions regarding uses, protective equipment, ventilation, flammability and
mixing of chemicals.
(8) Solid waste disposal — Designate a waste collection area on the construction site that does not receive a substantial
amount of runoff from upland areas and does not drain directly to a waterway. Ensure that containers have lids so
they can be covered before periods of rain and keep containers in a covered area whenever possible. Schedule
waste collection to prevent the containers from overfilling.
(9) Sanitary waste — Prevent the discharge of sanitary waste by providing convenient and well -maintained portable
sanitary facilities. Locate sanitary facilities in a convenient location away from waterways.
(10) Landscaping operations — Maintain as much existing vegetation as practicable. Apply permanent or temporary
stabilization, sodding and/or mulching to denuded areas in accordance with the erosion and sediment control
specifications and the general VPDES permit for discharges of stormwater from construction activities. Apply
nutrients in accordance with manufacturer's recommendations and not during rainfall events.

Section 8. Discharges to impaired waters, surface waters within an applicable TNML
wasteload allocation, and exceptional waters.
(Provide detailed measures for any applicable TMDL)
After construction, stormwater runoff will discharge to the stream buffer and floodplain of Moore's Creek via a vegetated
lip level spreader. According to the DEQ website, Moore's Creek is on the List of Impaired (Category 5) Waters in 2008*
for Escherichia coli and Fecal Coliform.
The operator shall implement the following items:
a) The impaired water(s), approved TMDL(s), and pollutant(s) of concern shall be identified in the SWPPP;
b) Permanent and temporary soil stabilization shall be applied to denuded areas within seven days after final grade is
reached on any portion of the site;
c) Nutrients shall be applied in accordance with manufacturer's recommendations or and approved nutrient
management plan and shall not be applied during rainfall events; and
d) The applicable SWPPP inspection requirements specified in Part II F 2 (of CGP) shall be amended as follows as
per Part I B 4 of the CGP:
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 rain events producing 0.25 inches of

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.

implementation prior to the next anticipated measurable storm event is impracticable, then
additional or alternative control measures shall be implemented as soon as practicable, but
no later than seven days after discovery or a longer period as established by the VSMP
authority.
G. SWPPP Inspections.
1. Personnel responsible for on -site and off -site inspections. Inspections required by this general
permit shall be conducted by the qualified personnel identified by the operator in the SWPPP.
The operator is responsible for ensuring that the qualified personnel conduct the inspection.
2. Inspection schedule.
a. For construction activities that discharge to a surface water identified in Part 11 B 5 and B
6 as impaired or having an approved TMDL or Part I B 7 as exceptional, the following
inspection schedule requirements apply:
(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
Page 14 of 26
there are more than 24 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.
b. Except as specified in Part II G 2 a, inspections shall be conducted at a frequency of:
(1) At least once every five business days; or
(2) At least once every 10 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 24 hours between business days, the inspection shall be
conducted on the next business day.
c. Where areas have been temporarily stabilized or land -disturbing activities will be
suspended due to continuous frozen ground conditions and stormwater discharges are
unlikely, the inspection frequency described in Part II G 2 a and 2 b may be reduced to
once per month. If weather conditions (such as above freezing temperatures or rain or
snow events) make discharges likely, the operator shall immediately resume the regular
inspection frequency.
d. Except as prohibited in Part II G 2 a (2), representative inspections may be utilized for
utility line installation, pipeline construction, or other similar linear construction activities
provided that:
(1) Temporary or permanent soil stabilization has been installed and vehicle access may
compromise the temporary or permanent soil stabilization and potentially cause
additional land disturbance increasing the potential for erosion;
(2) Inspections occur on the same frequency as other construction activities;
(3) Control measures are inspected along the construction site 0.25 miles above and
below each access point (i.e., where a roadway, undisturbed right-of-way, or other
similar feature intersects the construction activity and access does not compromise
temporary or permanent soil stabilization); and
(4) Inspection locations are provided in the inspection report required by Part II G.
e. If adverse weather causes the safety of the inspection personnel to be in jeopardy, the
inspection may be delayed until the next business day on which it is safe to perform the
inspection. Any time inspections are delayed due to adverse weather conditions, evidence
of the adverse weather conditions shall be included in the SWPPP with the dates of
occurrence.
3. Inspection requirements.
a. As part of the inspection, the qualified personnel shall:
(1) Record the date and time of the inspection and, when applicable, the date and rainfall
amount of the last measurable storm event;
Page 15 of 26
(2) Record the information and a description of any discharges occurring at the time of
the inspection or evidence of discharges occurring prior to the inspection;
(3) Record any land -disturbing activities that have occurred outside of the approved
erosion and sediment control plan;
(4) Inspect the following for installation in accordance with the approved erosion and
sediment control plan, identification of any maintenance needs, and evaluation of
effectiveness in minimizing sediment discharge, including whether the control has
been inappropriately or incorrectly used:
(a) All perimeter erosion and sediment controls, such as silt fence;
(b) Soil stockpiles, when applicable, and borrow areas for stabilization or sediment
trapping measures;
(c) Completed earthen structures, such as dams, dikes, ditches, and diversions for
stabilization and effective impoundment or flow control;
(d) Cut and fill slopes;
(e) Sediment basins and traps, sediment barriers, and other measures installed to
control sediment discharge from stormwater;
(f) Temporary or permanent channels, flumes, or other slope drain structures
installed to convey concentrated runoff down cut and fill slopes;
(g) Storm inlets that have been made operational to ensure that sediment laden
stormwater does not enter without first being filtered or similarly treated; and
(h) Construction vehicle access routes that intersect or access paved or public roads
for minimizing sediment tracking;
(5) Inspect areas that have reached final grade or that will remain dormant for more than
14 days to ensure:
(a) Initiation of stabilization activities have occurred immediately, as defined in
9VAC25-880-1; and
(b) Stabilization activities have been completed within seven days of reaching grade
or stopping work;
(6) Inspect for evidence that the approved erosion and sediment control plan, "agreement
in lieu of a plan," or erosion and sediment control plan prepared in accordance with
department -approved annual standards and specifications has not been properly
implemented. This includes:
Page 16 of 26
(a) Concentrated flows of stormwater in conveyances such as rills, rivulets, or
channels that have not been filtered, settled, or similarly treated prior to discharge,
or evidence thereof;
(b) Sediment laden or turbid flows of stormwater that have not been filtered or settled
to remove sediments prior to discharge;
(c) Sediment deposition in areas that drain to unprotected stormwater inlets or catch
basins that discharge to surface waters. Inlets and catch basins with failing
sediment controls due to improper installation, lack of maintenance, or inadequate
design are considered unprotected;
(d) Sediment deposition on any property (including public and private streets) outside
of the construction activity covered by this general permit;
(e) Required stabilization has not been initiated or completed or is not effective on
portions of the site;

f. The locations where any evidence identified under Part II G 3 a (6) exists;
g. The locations where any additional control measure is needed;
h. A list of corrective actions required (including any changes to the SWPPP that are
necessary) as a result of the inspection or to maintain permit compliance;
i. Documentation of any corrective actions required from a previous inspection that have not
been implemented; and
The date and signature of the qualified personnel and the operator or its duly authorized
representative.
5. The inspection report shall be included into the SWPPP no later than four business days after
the inspection is complete.
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.
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
department as well as obtain all applicable federal, state, and local authorizations,
approvals, and permits prior to the removal of sediments accumulated in surface waters
including wetlands.

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
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;

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:
"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.
Section 13. Inspection logs
Inspections of all Erosion Control, Stormwater Management, and Pollution Protection measures shall be made every five
business days and within 24 hrs of a 0.25 inch storm event and recorded on the attached inspection forms.
Rainfall Tracking
For the purposes of tracking measurable rain events, the operator will install, maintain, and reference a rain gauge
accessible to the inspection staff at the project site or at another local site representative of the project location.
Issued — 10/2019 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 cgpOepa.gov.
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 7 calendar days; or
• Once every 14 calendar days and within 24 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:
• 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.gov/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 all 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.er)a.Qov/nodes/stormwater/swoop. 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 projects 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 %z or more the above -ground height of the control (CGP Part 2.1.2.2.1b); (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 %z of the design capacity of the basin (CGP Part 2.1.3.2.1b). 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.er)a.ciov/npdes/stormwater/swt)pp. 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.

You are only required to complete this section if a discharge is occurring at the time of the inspection
Was a Stormwater Discharge Occurring From Any Part of Your Site At The Time of the Inspection?
During your inspection, examine all points of discharge from your site, and determine whether a discharge is occurring. If there is a discharge, answer 'yes" and
complete the questions below regarding the specific discharge. If there is not a discharge, answer "no" and skip to the next page.
Discharge Location (repeat as necessary if there are multiple points of discharge)
Location of discharge. Specify the location on your site where the discharge is occurring. The location may be an outlet from a stormwater control or constructed
stormwater channel, a discharge into a storm sewer inlet, or a specific point on the site. Be as specific as possible; it is recommended that you refer to a precise point
on your site map.
Describe the discharge. Include a specific description of any noteworthy characteristics of the discharge such as color; odor; floating, settled, or suspended solids;
foam; oil sheen; and other obvious pollution indicators.
Are there visible signs of erosion orsediment accumulation? At each point of discharge and the channel and streambank in the immediate vicinity, visually assess
whether there are any obvious signs of erosion and/or sediment accumulation that can be attributed to your discharge. If you answer "yes", include a description in
the space provided of the erosion and sediment deposition that you have found, specify where on the site or in the surface water it is found, and indicate whether

Contractor or Subcontractor Signature and Certification
Where a contractor or subcontractor is relied on to carry out the inspection and complete the inspection report, you should require the inspector to sign and certify
each report. Note that this does not relieve the permitted operator of the requirement to sign and certify the inspection report as well.
Signature and Certification by Permittee
At a minimum, the inspection report must be signed by either (1) the person who signed the NOI, or (2) a duly authorized representative of that person. The following
requirements apply to scenarios (1) and (2):
If the signatory will be the person who signed the NOI for permit coverage, as a reminder, that person must be one of the following types of individuals:
Fora corporation: A responsible corporate officer. For the purpose of this subsection, a responsible corporate officer means: (1) 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- 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 which 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 environmental 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
permit application requirements; and where authority to sign documents has been assigned or delegated to the manager in accordance with corporate
procedures.
Fora partnership orsole proprietorship: A general partner or the proprietor, respectively.
Fora municipality, state, federal, or other public agency: Either a principal executive officer or ranking elected official. For purposes of this subsection, a
principal executive officer of a federal 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 (e.g., Regional Administrator of EPA).
If the signatory will be a duly authorized representative, the following requirements must be met:
The authorization is made in writing by the person who signed the NOI (see above);
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 company. (A duly authorized representative may thus be either a named individual or any individual
occupying a named position); and
The signed and dated written authorization is included in the SWPPP. A copy must be submitted to EPA, if requested.
Corrective Action Report Form - Field Version
Purpose
This Corrective Action Report Form is designed to assist you in preparing corrective action reports for EPA's 2012
Construction General Permit (CGP). If you are covered under EPA's 2012 CGP, this form will enable you to
create a corrective action report that complies with the minimum reporting requirements of Part 5.4 of the
permit.
You are only required to fill out this form if one of the corrective action triggering conditions in Part 5.2.1 or 5.3
occurs on your site. Routine maintenance and repairs are generally not considered to be a corrective action
triggering condition. Corrective actions are triggered only for specific, more serious conditions that are identified
below in the "Overview of Corrective Action Requirements."
If you are covered under a state CGP, this form may be helpful in developing a report that can be used for that
permit; however it will need to be modified to meet the specific requirements of the permit. If your permitting
authority requires you to use a specific corrective action 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
Corrective Action Report Form, the actual obligations of regulated construction activities are determined by the
relevant provisions of the permit, not by the form. In the event of a conflict between the Corrective Action
Report Form and any corresponding provision of the 2012 CGP, you must abide by the requirements in the
permit. EPA welcomes comments on the Corrective Action Report Form at any time and will consider those
comments in any future revision of this document. You may contact EPA for CGP-related inquiries at
cao@eoa.aov.
Overview of Corrective Action Requirements
Construction operators covered under the 2012 CGP are required to conduct corrective actions and report on
progress made in correcting the problem condition(s) in accordance with the following requirements:
Corrective Action Triggering Conditions (Parts 5.2.1 and 5.3)
Corrective action is required whenever any of the following conditions occur at your site:
• A required stormwater control was never installed, was installed incorrectly, or not in accordance with the
requirements in Part 2 and/or 3;
• The stormwater controls (e.g., erosion and sediment controls or pollution prevention controls) that have been
installed and maintained are not effective enough for the discharge to meet applicable water quality standards
or applicable requirements in Part 3.1 of the permit;
A Part 2.3.1 prohibited discharge has occurred or is occurring; or
Any corrective actions required by EPA as a result of permit violations found during an inspection carded out
under Part 4.2.
Deadlines for Completing Corrective Actions (Part 5.2.1)
You must complete corrective action (e.g., installing and making operational any new or modified control, correcting
errors in installation, preventing, mitigating, or cleaning up spills or leaks making repairs) by no later than 7 calendar days
from the time of discovery of the condition. If infeasible to complete the installation or repair within 7 calendar days, you
must document why it is infeasible and document your schedule for completing the corrective action as soon as
practicable.
Deadlines for Documenting Corrective Actions in a Report (Part 5.4)
You are required to complete a corrective action report for each of corrective action you take in accordance with the
following deadlines.
Within 24 hours of discovering the occurrence of a corrective action triggering condition, you must document the
following:
- The condition identified at your site;
The nature of the condition identified; and
The date and time of the condition identified and how it was identified
Within 7 calendar days of discovering a triggering condition, you must document the following:
- Any follow-up actions taken to review the design, installation, and maintenance of stormwater controls,
including the dates such actions occurred;
- A summary of stormwater controls modifications taken or to be taken, including a schedule of activities
necessary to implement changes, and the date the modifications are completed or expected to be
completed; and
- Notice of whether SWPPP modifications are required as a result of the condition identified or corrective
action.
Instructions for Using This Report Form
This Field Version of the Corrective Action Report Form is intended to be used in the Feld and filled out by hand. If
you will be filling out the Corrective Action Report Form electronically (i.e., you will be typing in your findings),
please use the Electronic Version of the Corrective Action Report Form available at
www.epa.gov/npdes/stormwater/swpipp. The Electronic Version includes text fields with instructions for what to
enter.
The following tips for using this form will help you ensure that the minimum permit requirements are met:
• Review the corrective action requirements. Before you fill out this corrective action report form, read the
CGP's Part 5 corrective action requirements. This will ensure that you have a working understanding of the
permit's underlying corrective action requirements.
• Complete a separate report for each condition that triggers corrective action. For each triggering
condition on your site, you will need to fill out a separate corrective action report form.
• Complete all required text fields. Fill out all text fields. Only by filling out all fields will the form be compliant
with the requirements of the permit. (Note: Where you do not need the number of rows provided in the
corrective action report form, you leave those rows blank. Or, if you need more space to document your
findings, you may add an additional sheet.)
• Sign and certify each corrective action report. Each corrective action report form must be signed and
certified by the permittee to be considered complete. Where your corrective actions 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 form
includes a signature block for both parties.
• Include the corrective action report form with your SWPPP. Once your form is complete, make sure to
include a copy of the corrective action report form in your SWPPP in accordance with Part 7.2.12.4 of the
CGP.
• Retain copies of all corrective action reports with your records. You must retain copies of your corrective
action reports in your records in accordance with the requirements in Part 5.4.4 of the 2012 CGP. These
reports must be retained for at least 3 years from the date your permit coverage expires or is terminated.
