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 overlay district, except as
authorized by section 30.3 of this 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
P P � 9
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 owners 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
P P
waste area, and to comply with all other terms and 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 by the county engineer, the bond or
other surety, or 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:
I. 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 vehicles
load -bed can be
a on deposited public street.
P
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 any other activities associated with the final stabilization of the
area. The program authority may extend the date of completion upon the 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.

7. Stabilize Site & Demobilize
Name of Receiving Waters:
Rivanna River -Carroll Creek (HUC 020802040404 (JR17))
DEQ staff has determined that the proposed land -disturbing activity will discharge to a surface water identified as impaired or
for which a TMDL wasteload allocation has been established and approved prior to the term of the general permit for (i)
sediment or a sediment -related parameter or (ii) nutrients. Therefore, the following general permit (Part I.B.4) and SWPPP
requirements (Part H.A.5) must be implemented for the land -disturbing activity:
• 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

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 S WPPP 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 (31 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 fast 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 storm 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.

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.

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.
Corrective action notes can be found directly on the SWPPP reports.

2. Original specimen labels and materials safety data sheets will be kept on file; they contain important product
information.
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.
