PRIOR TO CONSTRUCTION
1. OWNER SHALL POST SURETY BONDS FOR CONSTRUCTION, EROSION & SEDIMENT
CONTROL.
2. CONTRACTOR SHALL OBTAIN PERMITS TO WORK WITHIN STATE RIGHT-OF-WAY (VDOT
LAND -USE PERMIT). BONDING FOR WORK WITHIN THE VDOT RIGHT-OF-WAY MAY BE
REQUIRED TO OBTAIN THE PERMIT.
3. CONTRACTOR SHALL COORDINATE WITH OWNER TO OBTAIN VSMP PERMITS, AS REQUIRED
BY THE STATE DEPARTMENT OF ENVIRONMENTAL QUALITY (DEQ).
4. CONTRACTOR SHALL OBTAIN LAND DISTURBANCE PERMIT FROM THE COUNTY OF
ALBEMARLE PRIOR TO BEGINNING CONSTRUCTION.
5. A PRE -CONSTRUCTION MEETING WITH THE ENGINEER, THE CERTIFIED LAND DISTURBER,
AND THE ENVIRONMENTAL INSPECTOR MAY ALSO BE REQUIRED. ALLOW 72 HOURS FOR
COORDINATION AND SCHEDULING OF PRE -CONSTRUCTION MEETING.
PROJECT DESCRIPTION
THE PURPOSE OF THIS OF THIS PLAN IS TO FILL AN EXISTING POND ON TMP
93-15. THE CONDITION OF THE POND OUTLET HAS DETERIORATED AND THE POND
SERVES NO OFFICIAL PURPOSE FOR STORMWATER QUALITY OR QUANTITY. THE FILL
OPERATION WILL EXTEND TO THE CONTRIBUTING DRAINAGE AREA WITHIN THE SUBJECT
PROPERTY IN ORDER TO PROMOTE SHEET FLOW OFF THE PROPERTY. AN ESTIMATED
15,000 CY OF IMPORT IS REQUIRED TO COMPLETE THIS PROJECT.
ADJACENT AREAS
THE PARCEL IS SURROUNDED BY ADJACENT RESIDENTIAL PARCELS CONSISTING OF MODERATE
TO STEEP SLOPING MAINTAINED GRASS, OPEN PASTURE, AND WOODED AREA.
SOILS
51B-BUGLEY CHANNERY SILT LOAM. (2% TO 7% SLOPES)
DEEP, SLIGHT SLOPING AND SOMEWHAT EXCESSIVELY DRAINED. STARTING AT SURFACE LAYER
TO SUBSTRATUM, SOIL LAYERS CONSIST OF CHANNERY SILT LOAM, VERY CHANNERY SILT
LOAM, AND BEDROCK. PERMEABILITY IS MODERATE WHILE AVAILABLE WATER CAPACITY IS VERY
LOW TO HIGH. SURFACE RUNOFF IS MEDIUM. HAZARD OF EROSION IS SLIGHT. HYDROLOGIC
SOIL GROUP D.
51D-BUGLEY CHANNERY SILT LOAM. (15% TO 25% SLOPES)
DEEP, STEEP SLOPING AND EXCESSIVELY DRAINED. STARTING AT SURFACE LAYER TO
SUBSTRATUM, SOIL LAYERS CONSIST OF CHANNERY SILT LOAM, VERY CHANNERY SILT LOAM,
AND BEDROCK. PERMEABILITY IS LOW WHILE AVAILABLE WATER CAPACITY IS VERY LOW.
SURFACE RUNOFF IS MEDIUM. HAZARD OF EROSION IS SLIGHT.
CRITICAL AREAS
THERE ARE CRITICAL SLOPES AS SHOWN ON SHEETS 2-4. THESE SLOPES MAY NOT BE
DISTURBED DUE TO AN INCREASE POTENTIAL FOR EROSION AND SEDIMENTATION..
STRUCTURAL PRACTICES
6. TEMPORARY CONSTRUCTION ENTRANCE (3.02) - A TEMPORARY CONSTRUCTION ENTRANCE
SHALL BE INSTALLED AT SITE ENTRANCE OFF OF OLD TRAIL DRIVE.
7. SILT FENCE BARRIER (3.05) - SILT FENCE BARRIERS WILL BE INSTALLED TO FILTER
RUNOFF FROM SHEET FLOW AS INDICATED ON THE EROSION AND SEDIMENT CONTROL
PLAN.
VEGETATIVE PRACTICES
8. TOPSOILING & STOCKPILING (3.30) - TOPSOIL WILL BE STRIPPED FROM AREAS TO BE
GRADED AND STOCKPILED FOR LATER USE. STOCKPILES ARE TO BE STABILIZED WITH
TEMPORARY VEGETATION OR TO HAVE SILT FENCE INSTALLED ALONG THE LOWER
PERIMETER TO PROTECT DOWNSTREAM AREAS.
9. TEMPORARY SEEDING (3.31) - AREAS NOT BROUGHT TO FINAL GRADE FOR A PERIOD OF
MORE THAN 14 DAYS SHALL BE STABILIZED WITH A TEMPORARY SEED MIXTURE
ACCEPTABLE FOR THAT TIME OF YEAR. CRIMPING, PUNCH ROLLER -TYPE ROLLERS, OR
TRACK WALKING MAY BE USED TO INCORPORATE STRAW MULCH INTO THE SOIL ON
SLOPES IF STRAW IS TO BE USED.
10. PERMANENT SEEDING (3.32) - AREAS BROUGHT TO FINAL GRADE OR THOSE
CONSTRUCTION AREAS THAT WILL REMAIN DORMANT FOR YEAR OR MORE SHALL BE
STABILIZED WITH A PERMANENT SEED MIXTURE ACCEPTABLE TO THAT TIME OF YEAR.
PREPARE SURFACE WITH APPROVED TREATMENT AND ADDITIVES PRIOR TO APPLYING SEED.
11. DUST CONTROL (3,39) - DUST CONTROL METHODS MUST BE USED TO REDUCE THE
AMOUNT OF AIRBORNE DUST DURING ALL PHASES OF CONSTRUCTION WHERE SOIL IS
EXPOSED OR DISTURBED.
MANAGEMENT STRATEGIES
12. THE CONSTRUCTION ENTRANCE AND PERIMETER EROSION CONTROL MEASURES SUCH AS
TREE PROTECTION AND SILT FENCE SHALL BE INSTALLED AS THE FIRST STEP OF
DISTURBANCE.
13. TEMPORARY SEEDING OR OTHER STABILIZATION METHODS, SUCH AS BASE AGGREGATE
WILL FOLLOW IMMEDIATELY AFTER REACHING FINAL GRADES.
14. ALL SEEDED AREAS WILL BE CHECKED REGULARLY TO ENSURE THAT A GOOD STAND IS
MAINTAINED. AREAS SHOULD BE FERTILIZED AND RE -SEEDED AS NEEDED TO ESTABLISH
GROWTH.
15. THE JOB SUPERINTENDENT SHALL BE RESPONSIBLE FOR THE INSTALLATION AND
MAINTENANCE OF ALL EROSION AND SEDIMENT CONTROL PRACTICES.
16. AFTER BEING NOTIFIED BY THE EROSION AND SEDIMENT CONTROL ADMINISTRATOR, THE
TEMPORARY EROSION AND SEDIMENT CONTROLS CAN BE CLEANED UP OR REMOVED, AND
THE SEDIMENT TRAPS CAN BE FILLED IN AND SEEDED, THEREBY REDIRECTING DRAINAGE
TO THE PERMANENT FACILITIES.
PERMANENT STABILIZATION
SEEDING SHALL BE DONE WITH KENTUCKY 31 TALL FESCUE IN ACCORDANCE TO STANDARD
AND SPECIFICATION 3.32, PERMANENT SEEDING, OF THE VIRGINIA EROSION AND SEDIMENT
CONTROL HANDBOOK. ANY FERTILIZER AND LIME APPLICATIONS SHALL BE IN ACCORDANCE
WITH SOIL TEST RESULTS. ALL SEEDED AREAS WILL BE STRAW MULCHED TO PROTECT
AGAINST RILL EROSION AND TO PRESERVE SOIL MOISTURE THAT WILL ENHANCE SEED
GERMINATION. CRIMPING, PUNCH ROLLER -TYPE ROLLERS, OR TRACK WALKING MAY BE USED TO
INCORPORATE STRAW MULCH INTO THE SOIL ON SLOPES IF STRAW IS TO BE USED.
EROSION CONTROL MAINTENANCE
1. IN GENERAL, ALL EROSION AND SEDIMENT CONTROL MEASURES SHALL BE CHECKED DAILY
AND AFTER EACH SIGNIFICANT RAINFALL. THE FOLLOWING ITEMS WILL BE CHECKED IN
PARTICULAR:
2. THE CONSTRUCTION ENTRANCE SHALL BE CHECKED DAILY FOR SOIL BUILDUP. IF THE
ENTRANCE BECOMES CLOGGED WITH SOIL AND FAILS TO PREVENT THE TRANSPORTATION
OF SOIL ONTO THE ROADWAY, ADDITIONAL STONE, REPLACEMENT OF STONE, OR A
WASH -RACK MAY BE REQUIRED.
3. SILT FENCE SHALL BE INSPECTED IMMEDIATELY AFTER EACH RAINFALL AND AT LEAST
DAILY DURING PROLONGED RAINFALL. CLOSE ATTENTION SHALL BE PAID TO THE REPAIR
OF DAMAGED SILT FENCE RESULTING FROM END RUNS AND UNDERCUTTING. SHOULD THE
FABRIC ON A SILT FENCE DECOMPOSE OR BECOME INEFFECTIVE PRIOR TO THE END OF
THE EXPECTED USABLE LIFE AND THE BARRIER STILL BE NECESSARY THE FABRIC SHALL
BE REPLACED PROMPTLY. SEDIMENT DEPOSITS SHOULD BE REMOVED AFTER EACH STORM
EVENT. THEY MUST BE REMOVED WHEN DEPOSITS REACH APPROXIMATELY ONE-HALF THE
HEIGHT OF THE BARRIER. ANY SEDIMENT DEPOSITS REMAINING IN PLACE AFTER THE SILT
FENCE IS NO LONGER REQUIRED SHALL BE DRESSED TO CONFORM WITH THE EXISTING
GRADE, PREPARED, AND SEEDED.
4. STORMWATER CONVEYANCE CHANNELS (WHERE APPLICABLE):
4.1. GRASS LINED CHANNELS - DURING THE INITIAL ESTABLISHMENT, GRASS LINED
CHANNELS SHOULD BE REPAIRED IMMEDIATELY AND RE-ESTABLISHED IF NECESSARY.
AFTER GRASS HAS BECOME ESTABLISHED, THE CHANNEL SHOULD BE CHECKED
PERIODICALLY TO DETERMINE IF THE GRASS IS WITHSTANDING FLOW VELOCITIES
WITHOUT DAMAGE. IF THE CHANNEL IS TO BE MOWED, IT SHOULD BE DONE IN A
MANNER THAT IT WILL NOT DAMAGE THE GRASS.
5. ALL SEEDED AREAS WILL BE CHECKED REGULARLY TO ENSURE THAT A GOOD STAND IS
MAINTAINED. AREAS SHOULD BE FERTILIZED AND RE -SEEDED AS NEEDED. IN THE
EVENT THAT THE APPLIED SEEDING FAILS TO TAKE HOLD, BLANKET MATTING SHALL BE
PLACED IN APPROPRIATE AREAS DEEMED NECESSARY BY THE ENGINEER OR EROSION
CONTROL INSPECTOR.
SEQUENCE OF CONSTRUCTION
1. AFTER OBTAINING ALL REQUIRED PERMITS THE CONTRACTOR SHALL COORDINATE A
PRE -CONSTRUCTION MEETING, ALLOWING 72 HOURS FOR ITS COORDINATION.

Sec. 5.1.28 - Borrow, fill or waste areas.
a. Each borrow, fill or waste area shall be subject to the following:
1. Each active borrow, fill or waste area shall be shaped and sloped so that no undrained pockets or stagnant pools of water are
created to the maximum extent reasonably practicable as determined by the program authority. All undrained pockets and stagnant
pools of water resulting from drainage shall be treated as required by the Virginia Department of Health to eliminate breeding places
for mosquitoes and other insects.
2. No fill or waste area shall be located either within the flood hazard overlaydistrict except as authorized b section 30.3 of this
� P Y
chapter, or in any stream buffer area as defined by Chapter 17 of the Code of Albemarle. (Amended 10-3-01; 7-3-02)
3. Each fill or waste area shall be only for the disposal of soil or inert materials. The disposal of any other materials in a fill or
waste area is prohibited.
4. Each borrow, fill or waste area shall be reclaimed within seven days of completion of the borrow, fill or waste activity, or such
later time authorized by the program authority for reclamation activities of a seasonal nature. Reclamation shall include, but not be
limited to, restoring the area so that it approximates natural contours; shaping and sloping the area to satisfy the requirements of
subsection (a)(1); covering the area with clean fill to a minimum depth of two feet in order to allow for permanent stabilization and
reclamation; and establishing a permanent vegetative ground cover; provided that the program authority may reduce the minimum
depth of clean fill to one foot if the area is unlikely to be redeveloped.
5. The zoning administrator, or the program authority for those borrow, fill or waste areas subject to subsection (b), may require the
owner to submit a reasonable performance bond with surety, cash escrow, letter of credit, any combination thereof, or such other
legal arrangement acceptable to the county attorney, to ensure that measures could be taken by the county or the program
authority at the owner's expense should he fail, after notice is given to perform required reclamation work specified in the notice.
The amount of the bond or other surety shall be based on unit pricing for new public or private sector construction in Albemarle
County, Virginia, and a reasonable allowance for estimated administrative costs and inflation which shall not exceed 25 percent of the
estimated cost to initiate and complete the reclamation of the borrow, fill or waste area and to with all other terms and
P � comply
conditions of the plan or narrative required by subsection (b). If reclamation work is required to be taken by the county or the
program authority upon the failure of the owner to do so, the county or the program authority may collect the reasonable cost of
the work directly from the owner, to the extent that the cost exceeds the unexpended or unobligated amount of the surety. Within
60 days after the reclamation work is completed and inspected and approved b the count engineer, the bond or other surety, or
Y P P PP Y Y 9 Y�
any unexpended or unobligated portion thereof, shall be refunded to the owner.
b. If the aggregate area of a borrow, fill or waste activity will be greater than 10,000 square feet, then, as part of any permit issued
pursuant to section 17-207 of the Code of Albemarle, the program authority shall first approve a plan or a narrative for such activity
that satisfies the requirements of subsection a and the following:
q () 9
1. All inert materials shall be transported in compliance with section 13-301 of the Code of Albemarle. Before a transporting vehicle
leaves the parcel or parcels on which the borrow, fill or waste area is located, it shall be cleaned so that no inert materials outside
of the vehicle's load -bed can be deposited on a public street.
2. The borrow, fill or waste area and the access roads thereto shall be treated or maintained to prevent dust or debris from blowing
or spreading onto adjacent properties or public streets. Depending on the anticipated intensity and duration of the activity and the
character of the development of adjoining properties, the program authority may require setback, fencing and landscaping
requirements as deemed appropriate, but which shall not exceed the requirements of sections 30.4.6, 30.4.7 and 30.4.9 of this
chapter.
3. Borrow, fill or waste activity involving industrial -type power equipment shall be limited to the hours of 7:00 a.m. to 9:00 p.m.,
except in cases of a public emergency declared pursuant to section 2-1003 of the Code of Albemarle.
4. Borrow, fill or waste activity shall be conducted in a safe manner that maintains lateral support, in order to minimize any hazard
to persons, physical damage to adjacent land and improvements, and damage to any public street because of slides, sinking, or
collapse.
5. The placement of fill or waste shall be completed within one year of its commencement except for reclamation activities and an
P P Y � P Y
other activities associated with the final stabilization of the area. The program authority may extend the date of completion upon the
P 9 Y Y P P
written request of the applicant, demonstrating that factors beyond the control of the applicant prevented the completion within the
one-year period. The program authority may then extend the permit for a period of time that, in its sole discretion, is determined
adequate to complete the work.
6. In lieu of a plan or narrative, the program authority may accept a contractual agreement between the Virginia Department of
Transportation and its contractor for a public road project; provided that the program authority determines that the agreement
satisfies at least to an equivalent extent the requirements and intent of this section.

PURPOSE
4VAC50-60-54 of the Virginia Stormwater Management Program (VSMP) Permit
Regulations requires that Stormwater Pollution Prevention Plan (SWPPP) be developed
for all regulated land disturbing activities. The SWPPP must include, but not be limited
to an approved erosion and sediment control plan, an approved stormwater
management Ian and this Pollution Prevention Plan PPP for regulated land
9 P (PPP) 9
disturbing activities, and a description of any additional control measures necessary to
address a TMDL as applicable.
The plan for implementing pollution prevention measures during construction activities
developed on this sheet must be implemented and updated as necessary. Any PPP
requirements not included on this sheet must be incorporated into the SWPPP required
by 4VAC50-60-54 that must be developed before land disturbance commences. This
PPP identifies potential sources of pollutants that may reasonable be expected to affect
the quality stormwater discharges from the construction site (both on- and off -site
activities) and describes control measures that will be used to minimize pollutants in
stormwater discharges from the construction site.
OTHER REFERENCED PLANS
SWPPP requirements may be fulfilled by incorporating, by reference, other plans. All
plans incorporated by reference become enforceable under the VSMP Permit
Regulations and General Permit VAR10 for Discharges of Stormwater from
Construction Activities. If a plan incorporated by reference does not contain all of the
required elements of the PPP, the operator must develop the missing elements and
include them in the SWPPP.

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.

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

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;
3. Failure or taking out of service of some or all of the facilities; and

I. Reports of noncompliance. The operator shall report any noncompliance which may adversely
affect surface waters or may endanger public health.
An oral report to the department and the VSMP authority shall be provided within 24 hours
from the time the operator becomes aware of the circumstances. The following shall be
included as information that shall be reported within 24 hours under this subdivision:
a. Any unanticipated bypass; and
b. Any upset that causes a discharge to surface waters.
2. A written report shall be submitted within five days and shall contain:
a. A description of the noncompliance and its cause;
Page 21 of 26
b. The period of noncompliance, including exact dates and times, and if the noncompliance
has not been corrected, the anticipated time it is expected to continue; and
c. Steps taken or planned to reduce, eliminate, and prevent reoccurrence of the
noncompliance.
The department may waive the written report on a case -by -case basis for reports of
noncompliance under Part III I if the oral report has been received within 24 hours and no
adverse impact on surface waters has been reported.
3. The operator shall report all instances of noncompliance not reported under Part III 1 1 or 2 in
writing as part of the SWPPP. The reports shall contain the information listed in Part 111 1 2.
NOTE: The reports required in Part III G, H and I shall be made to the department and the VSMP
authority. Reports may be made by telephone, email, or by fax. For reports outside normal working
hours, leaving a recorded message shall fulfill the immediate reporting requirement. For
emergencies, the Virginia Department of Emergency Management maintains a 24-hour telephone
service at 1-800-468-8892.
4. Where the operator becomes aware of a failure to submit any relevant facts, or submittal of
incorrect information in any report, including a registration statement, to the department or the
VSMP authority, the operator shall promptly submit such facts or correct information.
J. Notice of planned changes.
1. The operator shall give notice to the department and the VSMP authority as soon as possible
of any planned physical alterations or additions to the permitted facility or activity. Notice is
required only when:
a. The operator plans an alteration or addition to any building, structure, facility, or installation
that may meet one of the criteria for determining whether a facility is a new source in
9VAC25-870-420;
b. The operator plans an alteration or addition that would significantly change the nature or
increase the quantity of pollutants discharged. This notification applies to pollutants that
are not subject to effluent limitations in this general permit; or
2. The operator shall give advance notice to the department and VSMP authority of any planned
changes in the permitted facility or activity, which may result in noncompliance with state
permit requirements.
K. Signatory requirements.
1. Registration statement. All registration statements shall be signed as follows:
a. For a corporation: by a responsible corporate officer. For the purpose of this chapter, a
responsible corporate officer means: (i) a president, secretary, treasurer, or vice-president
of the corporation in charge of a principal business function, or any other person who
performs similar policy -making or decision -making functions for the corporation; or (ii) the
manager of one or more manufacturing, production, or operating facilities, provided the
Page 22 of 26
manager is authorized to make management decisions that govern the operation of the
regulated facility including having the explicit or implicit duty of making major capital
investment recommendations, and initiating and directing other comprehensive measures
to assure long-term compliance with environmental laws and regulations; the manager
can ensure that the necessary systems are established or actions taken to gather
complete and accurate information for state permit application requirements; and where
authority to sign documents has been assigned or delegated to the manager in
accordance with corporate procedures;
b. For a partnership or sole proprietorship: by a general partner or the proprietor,
respectively; or
c. For a municipality, state, federal, or other public agency: by either a principal executive
officer or ranking elected official. For purposes of this chapter, a principal executive officer
of a public agency includes (i) the chief executive officer of the agency or (ii) a senior
executive officer having responsibility for the overall operations of a principal geographic
unit of the agency.
2. Reports and other information. All reports required by this general permit, including SWPPPs,
and other information requested by the board or the department shall be signed by a person
described in Part III K 1 or by a duly authorized representative of that person. A person is a
duly authorized representative only if:
a. The authorization is made in writing by a person described in Part III K 1;
b. The authorization specifies either an individual or a position having responsibility for the
overall operation of the regulated facility or activity such as the position of plant manager,
operator of a well or a well field, superintendent, position of equivalent responsibility, or
an individual or position having overall responsibility for environmental matters for the
operator. (A duly authorized representative may thus be either a named individual or any
individual occupying a named position); and
c. The signed and dated written authorization is included in the SWPPP. A copy shall be
provided to the department and VSMP authority, if requested.
3. Changes to authorization. If an authorization under Part III K 2 is no longer accurate because
a different individual or position has responsibility for the overall operation of the construction
activity, a new authorization satisfying the requirements of Part III K 2 shall be submitted to
the VSMP authority as the administering entity for the board prior to or together with any
reports or information to be signed by an authorized representative.
4. Certification. Any person signing a document under Part III K 1 or 2 shall make the following
certification:
"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.

• Permanent or temporary soil stabilization shall be applied to denuded areas within seven (7) days after final grade is
reached on any portion of the site.
• Nutrients (e.g. fertilizers) shall be applied in accordance with manufacturer's recommendations or an approved nutrient
00management plan and shall not be applied during rainfall events.
• Inspections shall be conducted at a frequency of (i) at least once every four (4) business days or (ii) at least once every
five (5) 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
neat business day.
• Representative inspections used by utility line installation, pipeline construction, or other similar linear construction
activities shall inspect all outfalls.

Erosion and Sediment Controls:
Approved erosion and sediment control plans are incorporated by reference as part of this Stormwater Pollution Prevention
Plan. Approved plans are included in this SWPPP binder.
Stabilization Practices:
1. The purpose of the erosion control measures shown on these plans shall be to preclude the transport of all waterborne
sediments resulting from construction activities from entering onto adjacent properties of state waters. If field inspection
reveals the inadequacy of the plan to confine sediment to the project site, appropriate modifications will be made to correct any
plan deficiencies. In addition to these notes, all provisions of the Virginia Erosion and Sediment Control Regulations shall
apply to this project.
2. All erosion and sediment control measures shall be installed and maintained in accordance with the Virginia Erosion
and sediment Control Handbook (3`a Edition, 1992) and Virginia Regulations VR 625-02-00 Erosion and Sediment control
Regulations. The contractor shall be thoroughly familiar with all applicable measures contained therein which may be pertinent
to this project.
3. All points of construction ingress and egress shall be protected by a temporary paved construction entrance, with a
wash rack, to prevent tracking of mud onto public right-of-ways. An entrance permit from VDOT is required prior to any
construction activities within state right-of-ways. Where sediment is transported onto a public road surface, the road shall be
thoroughly cleaned at the end of each day. Sediment shall be removed from the roads by shoveling or sweeping and
transported to a sediment control disposal area. Street washing shall be allowed only after sediment is removed in this manner.
This provision shall apply to individual subdivision lots as well as to larger land disturbing activities.
4. The Albemarle County Department of Community Development schedules the pre -construction meeting; therefore, the
developer, project engineer, or contractor must contact the Albemarle County Department of Community Development in
order to schedule a preconstruction meeting. The preconstruction meeting shall be held at the Albemarle County Office
Building between the County, the developer, the project engineer, and the contactor prior to issuance of the land disturbing
permit. The contractor shall submit a sequence of construction to the County for approval prior to the preconstruction meeting.
The contractor will supply code compliance with the name of the individual who will be responsible for any maintenance of
installed measures that is required. The SWPPP Inspector will be in contact with this person to ensure that the necessary
maintenance of the installed measures is taking place on a daily basis. The Albemarle County Department of Community
Development must be notified one week prior to the preconstruction conference, one week prior to the commencement of land
disturbing activity, and one week prior to the final inspection.
A copy of the approved erosion and sediment control plan shall be maintained on the site at all times.
6. Sediment basins and traps, perimeter dikes, sediment barriers, and other measures intended to trap sediment onsite must
be constructed as a first step in grading and be made functional before upslope land disturbance takes place. Earthen structures
such as dams, dikes, and diversions must be seeded and mulched immediately after installation. Periodic inspections of the
erosion control measures shall be made to assess their condition. Any necessary maintenance of the measures shall be
accomplished immediately upon notification by the SWPPP Inspector and shall include the repair of measures damaged by any
subcontractor including those of the public utility companies.
7. The contractor is responsible for installation of any additional erosion control measures necessary to prevent erosion
and sedimentation as determined by the plan approving authority.
8. All disturbed areas are to drain to approved sediment control measures at all times during all land disturbing activities
and during site development until final stabilization is achieved.
9. Sediment control measures may require minor field adjustments at time of construction to insure their intended purpose
is accomplished. Division of code compliance approval will be required for other deviations from the approved plans.
10. Surface flows over cut and fill slopes shall be controlled by either redirecting flows from traversing slopes or by
installing mechanical devices to safely lower water down slope without causing erosion. A temporary fill diversion (std. 3.09
and spec. 3.10) can be installed prior to the end of each working day.
11. During dewatering operations, water will be pumped into an approved filtering device.
12. The contractor shall place soil stockpiles at the locations shown on the SWPPP plan sheet for each area of construction,
or as directed by design engineer. Soil stockpiles shall be stabilized or protected with sediment trapping measures
immediately. Offsite waste or borrow areas shall be approved by the division of code compliance prior to the import of any
borrow or export of any waste to or from the project.
13. Prior to commencing land disturbing activities in areas other than indicated on these plans (including, but not limited
to, offsite borrow or waste areas), the contractor shall submit a supplementary erosion control plan to the owner for review and
approval by the plan approving authority.
14. The contactor shall complete drainage facilities within 30 days following completion of rough grading at any point
within the project. The installation of drainage facilities shall take precedence over all underground utilities. Outfall ditches
from drainage structures shall be stabilized immediately after construction of same. This includes installation of erosion
control stone or paved ditches where required. Any drainage outfalls required for a street must be completed before street
grading or utility installation begins.
15. Permanent or temporary soil stabilization must be applied to all denuded areas within 7 days after final grade is reached
on any portion of the site. Soil stabilization must also be applied to denuded areas which may be a final grade but will remain
dormant (undisturbed) for longer than 14 days. Soil stabilization measures include vegetative establishment, mulching and the
early application of gravel base material on areas to be paved.
16. No more than 300 feet of sanitary storm sewer, waterlines, or underground utility lines are to be immediately stabilized
(i.e., the same day).
17. If disturbed area stabilization is to be accomplished during the months of November, December, January or February,
stabilization shall be accomplished by permanently seeding the area with a seeding mixture that includes the seasonal nurse
crop for the Piedmont area, which is Winter Rye. See Table 3.32-D for a list of site specific seeding mixtures for the Piedmont
area. This is in accordance with Specification 3.32 from the Virginia Erosion and Sediment Control Handbook (VESCH). The
seeding area will also need to be mulched in order to assist the growth of the seeding in the winter months (Specification 3.35
of the VESCH). For temporary seeding stabilization during these months, a 50150 mix of annual ryegrass and winter ryegrass,
as well as a mulching cover should be put down according to Specification 3.31 of the VESCH, Table 3.31-B.
18. The term seeding, final vegetative cover or stabilization, on this plan shall mean the successful germination and
establishment of a stable grass cover from a properly prepared seedbed containing the specified amounts of seed, lime, and
fertilizing in accordance with Specification 3.32, permanent seeding. Irrigation shall be required as necessary to ensure
establishment of grass cover.
19. All slopes steeper than 3:1 shall require the use of erosion control blankets such as Excelsior blankets to aid in the
establishment of a vegetative cover that is hardier than grass. Matting or mulch matting may also be used on recently planted
slopes in order to protect the seeding until the vegetative cover becomes established on the slopes. Installation shall be in
accordance with Specification 3.35, mulching and manufacturer's instructions. No slopes shall be created steeper than 2:1.
20. Inlet protection in accordance with Specification 3.07 shall be provided for all stone drain inlets as soon as practical
following construction of same.
21. All temporary erosion and sediment control measures shall be removed within 30 days after final site stabilization or
after the temporary measures are no longer needed, unless otherwise authorized by the local program administrator. Trapped
sediment and disturbed soil areas resulting from the disposition of temporary measures shall be permanently stabilized to
prevent further erosion and sedimentation.
22. If Applicable- As -built drawings must be provided for all detention/BMP facilities. Also upon completion, the
construction of all detentionBMP facilities shall be certified by a professional engineer who inspected the structure during
construction. The certification shall state that to the best of his/her judgment, knowledge, and belief, the structure was
constructed in accordance with the approval plans and specifications.

12. Storm Drain Inlet Protection
13. Riprap
14. Tree Preservation and Protection
Waste Materials:
All waste materials will be collected and stored in a proper receptacle in accordance with all local and State solid waste
management regulations. All trash and construction debris from the site will be deposited in dumpsters. The trash will be
hauled to an appropriate waste disposal site. No construction waste materials will be buried onsite. All project personnel will
be instructed regarding the correct procedure for waste disposal.
Hazardous Waste:
All hazardous waste materials will be disposed of in the manner specified by the manufacturer and as required by local or State
regulation. Site personnel will be instructed in these practices.
Sanitary Waste:
All sanitary waste will be collected from the portable units as required by local and State regulation.
Offsite Vehicle Tracking:
Stabilized construction entrances will be provided to help reduce vehicle tracking of sediments. The paved street adjacent to
the site entrance will be swept as needed to remove any excess mud, dirt or rock tracked from the site. Dump trucks hauling
material from the construction site will be covered with a tarpaulin.
Timing of Controls and Measures:
As indicated in the Stabilization Practices, permanent or temporary soil stabilization must be applied to all denuded areas
within 7 days after final grade is reached on any portion of the site. Soil stabilization must also be applied to denuded areas
which may not be a final grade but will remain dormant (undisturbed) for longer than 30 days. Soil stabilization measures
include vegetative establishment, mulching and the early application of gravel base material on areas to be paved.
Certification of Compliance with Federal, State and Local Requirements:
The Stormwater Pollution Prevention Plan reflects State requirements for stormwater management and erosion and sediment
control, as established in the Virginia Stormwater Management Handbook and Virginia Erosion and Sediment Control Manual.
Maintenance and Inspection Procedures:
Inspections of the construction site shall be made by the SWPPP Inspector or by other qualified members of the Pollution
Prevention Team.
Erosion and sediment control measures identified in the plan shall be observed to ensure that they are still operating correctly.
The contractor shall inspect all erosion control measures at least once every 4 or 5 business days and after each significant
rainfall producing event. Any necessary repairs or cleanup to maintain the effectiveness of the erosion control devices shall be
made within seven (7) days.
Inspections shall be conducted (i) at least once every four (4) business days or (ii) at least once every five (5) 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. These inspections
shall cover disturbed areas that have not been finally stabilized, areas used for storage of materials that are exposed to
precipitation, structural control measures, and locations where vehicles enter or exit the site.
Where areas have been finally or temporarily stabilized or runoff is unlikely due to winter conditions (e.g. site is covered with
snow, ice or frozen ground exists) such inspections shall be conducted at least once every month. If weather conditions (such a
above freezing temperatures or rain/snow events) make discharges likely, the operator shall immediately resume the regular
inspection frequency.
Reports summarizing each inspection shall be retained onsite as part of this Stonnwater Pollution Prevention Plan.
Each inspection report shall include the following items:
a) The date and time of the inspection and when applicable, the date and rainfall amount of the last measurable storm
event
b) Summarized findings of the inspection
c) The location(s) of prohibited discharges
d) The location(s) of controlled measures that require maintenance
e) The location(s) of control measures that failed to operate as designed or proved inadequate or inappropriate for a
particular location
f) The location(s) where any evidence identified under Park II G3a(7) exists
g) The location(s) where any additional control measure is needed that did not exist at the time of inspection

1. Corrective Action and Forms
The operator shall implement the corrective action(s) 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.
The contractor shall be responsible for the installation and maintenance of all erosion and sediment control practices
and for corrective actions.
Corective action notes can be found directly on the SWPPP reports.
II. Grading and Stabilization Activities Log

III. Material Management Practices:
The following are the materials management practices that will be used to reduce the risk of spills or other accidental
exposure of materials and substances to stormwater runoff.
(a) Employee Training:
Employee training with regard to material management practices is conducted at the site. Training includes
discussions of spill response, good housekeeping, and other material management practices. Employee training
generally occurs with each new employee once hired by the site contractor.
(b) Good Housekeeping:
The following good housekeeping practices will be followed onsite during the construction project.
1. All materials stored onsite will be stored in a neat, orderly manner in their appropriate containers.
Materials which have the potential for contaminating runoff during storm events will be stored in
their appropriate watertight containers, stored under a canopy, tarpaulin, shrink wrapped or otherwise
precluded from direct exposure of precipitation.
2. Empty containers that may contain chemical residues shall be disposed of in accordance with State
and Local regulations.
3. Products, where possible, will be kept in their original containers with the original manufacture's
label.
4. Chemical or petroleum products will not be mixed with one another unless recommended by the
manufacturer.
5. Whenever possible, all of a product will be used up before disposing of the container.
6. Manufacturer's recommendations for proper use and disposal will be followed.
7. The site superintendent will inspect daily to ensure proper use and disposal of materials onsite.
IV. Hazardous Products:
These practices are used to reduce the risk associated with hazardous materials.
1. Products will be kept in original containers unless they are not resealable.
2. Original specimen labels and materials safety data sheets will be kept on file; they contain important product
information.
3. If surplus product must be disposed of, manufacturers and/or local and State recommended methods for proper
disposal will be followed.
Material Safety Data Sheets (MSDS) will be available for all chemical materials used onsite and will be located with
the SWPPP binder.
V. Product Specific Practices:
The following product specific practices will be followed onsite:
(a) Petroleum Products:
1. All onsite vehicles will be monitored for fluid leaks and will receive regular preventive maintenance
to reduce the chance of leakage.
2. It is recommended that, if practicable, all refueling, repair and changing of equipment and vehicle
fluids shall be conducted in a designated area, with the use of either spill buckets and/or fuel spill
mats to reduce the potential for contamination. This area will be designed in a manner to reduce the
potential for contamination of onsite resources. For refueling, repair and changing of equipment and
vehicle fluids outside of the designated areas, care should be taken to avoid activities within +/- 50
feet of wetlands, streams, water bodies, tree preservation areas or any other environmentally
sensitive areas.
3. Petroleum products will be stored in tightly sealed containers which are clearly labeled.
4. An area will be designated for the collection and storage of all chemical and storage of all chemical
and petroleum based products and containers for those products. The containers shall be protected
from rain events. These areas are identified on the SWPPP/PPP Reference Drawing included with
the "Final Construction Plans" for each block.
5. Any asphalt substances used onsite will be applied according to the manufacturer's
recommendations.
6. The project superintendent will regularly inspect the site to insure proper disposal methods of used
antifreeze, oils, filters and other hazardous materials are followed.
(b) Fertilizers:
Fertilizers used will be applied according to manufacturer's product standards. The contents of any partially
used bags of fertilizer will be transferred to a sealable plastic container to avoid spills.
(c) Paints:
All containers will be tightly sealed and stored when not required for use. Excess paint will be properly
disposed of according to manufacturers' instructions or State and local regulations.
(d) Concrete Trucks:
Concrete trucks will only wash out or discharge surplus concrete or drum wash water at approved locations in
accordance with State and local regulations. These areas are identified on the SWPPP/PPP Reference Drawing
included with the "Final Construction Plans" for each block.
VI. Spills and Leaks:
This section normally contains a list of significant spills and significant leaks of toxic or hazardous pollutants that
occurred at areas that are exposed to precipitation or that otherwise drain to a stormwater conveyance at the facility
within the 3 year period immediately prior to the date of submission of a registration statement to be covered under this
permit.
No significant spills and/or leaks have occurred at the site of toxic or hazardous pollutants at areas that are exposed to
precipitation.
VII. Spill control Practices:
In addition to the good housekeeping and material management practices discussed in the previous sections of this plan,
the following practices will be followed for spill prevention and cleanup:
1. Manufacturers' recommended methods for spill cleanup will be clearly posted and site personnel will be made
aware of the procedures and the location of the information and cleanup supplies.
2. Materials and equipment necessary for spill cleanup will be kept in the material storage area onsite. Equipment and
materials may include but not be limited to brooms, dust pans, mops, rags, gloves, goggles, absorbent material (e.g.
kitty litter, sand, sawdust) and plastic and metal trash containers.
3. All spills will be cleaned up immediately after discovery.
