Section 3. Nature of activity
GENERAL SITE INFORMATION:
The purpose of the land -disturbing activity is to remove the existing asphalt plant and the installation of a new asphalt plant.
The total permitted site is 4.4 acres (extent of site development plan application) and the estimated area to be disturbed is 2.89
acres and 0.24 acres of off site disturbance. The site consists of a working asphalt plant that operates in a leased area within
the parcel (TMP 88-18) for the Red Hill Quarry. The existing lease area is a gravel covered area with the existing stockpiles
of aggregate that is used in the manufacture of asphalt mix. Adjacent areas include an existing creek to the west that is
associated with a 100" stream buffer and floodplain that is located within the development area. Further to the west is a
vacant parcel owned by Martin Marietta, the owners of The Quarry. The vacant parcel is currently covered by trees. To the
north of the lease area is vacant land located on the Quarry Parcel which has not been disturbed by quarry operations as of
this date. To the ease of the lease area is the active quarry operations that supply aggregate to the asphalt plant. To the south
of the lease area is Route 708, Red Hill Road. Offsite areas include some grading and construction activities that will be
taking place outside the eastern boundary of the lease area (0.24 acres). These activities should be coordinated with the quarry
operations.

Section 4. Erosion and Sediment Control Plan.
(Provide a reduced, 11x17 copy of the latest Erosion and Sediment Control Plan. Do not reference only.)
Approved erosion and sediment control plans for S.L. Williamson Asphalt Plant at Red Hill Quarry are incorporated by
reference as part of this Stormwater Pollution Prevention Plan. Approved plans are included in this SWPPP binder.
1. The purpose of the erosion control measures shown on these plans shall be to preclude the transport of all waterbome
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 9VAC25-840 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 construction entrance to prevent tracking of mud
onto public right-of-way. An entrance permit from VDOT is required prior to any construction activities within state
rights -of -way. 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.
4. A copy of the approved erosion and sediment control plan shall be maintained on the site at all times.
5. 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.
6. Sediment traps and sediment basin shall be designed and constructed based upon the total drainage area to be served
by the trap or basin.
a. The minimum storage capacity of a sediment trap shall be 134 cubic yards per acre of drainage area and the trap
shall only control drainage areas less than three acres (see sizing table for dimensions).
b. Surface runoff from disturbed areas that is comprised of flow from drainage areas greater than or equal to three
acres shall be controlled by a sediment basin. The minimum storage capacity of a sediment basin shall be 134
cubic yards per acre of drainage area. The outfall system shall, at a minimum, maintain the structural integrity of
the basin during a twenty -five-year storm of 24-hour duration. Runoff coefficients used in runoff calculations
shall correspond to a bare earth condition or those conditions expected to exist while the sediment basin is
utilized.
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.
Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County
9. Sediment control measures may require minor field adjustments at time of construction to ensure their intended
purpose is accomplished. Division of code compliance approval will be required for other deviations from the
approved plans.
10. Concentrated runoff shall not flow down cut or fill slopes unless contained within an adequate temporary or
permanent channel, flume or slope drain structure.
11. 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. During construction, 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.
12. 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.
13. 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. Temporary soil stabilization shall be applied within seven days to denuded areas
that may not be at final grade but will remain dormant for longer than 14 days. Permanent stabilization shall be
applied to areas that are to be left dormant for more than one year. Soil stabilization measures include vegetative
establishment, mulching and the early application of gravel base material on areas to be paved. Contractor shall
establish a stabilized site and not allow any erosion or sediment to exit.
14. 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.
15. 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.
16. Underground utility lines (water, sewer, power, cable, or gas) shall be installed in accordance with the following
standards in addition to other applicable criteria.
a. No more than 500 linear feet of trench may be opened at one time.
b. Excavated material shall be placed on the uphill side of trenches.
c. Effluent from dewatering operations shall be filtered or passed through an approved sediment trapping device, or
both and discharged in a manner that does not adversely affect flowing streams or off -site property.
d. Material used for back filling trenches shall be properly compacted in order to minimize erosion and promote
stabilization.
e. Re -stabilization shall be accomplished in accordance with these regulations.
f. Applicable safety regulations shall be complied with.
17. Cut and fill slopes shall be designed and constructed in a manner that will minimize erosion. Slopes that re found to
be eroding excessively within one year of permanent stabilization shall be provided with additional slope stabilizing
measures until the problem is resolved.
Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County
18. All storm sewer inlets that are made during construction shall be protected so that sediment -laden water cannot enter
the conveyance system without first being filtered or otherwise treated to remove sediment.
19. Before newly constructed stone water conveyance channels or pipes are made operational, adequate outlet protection
and any required temporary or permanent channel lining shall be installed in both the conveyance channel and
receiving channel.
20. 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.
Structural and Vegetative Practices:
The following erosion and sediment control structural and vegetative practices will be incorporated on the project site:
1. Safety Fence (3.01) - A temporary safety fence shall be erected to prohibit public access to the project area and around
sensitive areas to protect them from construction traffic.
2. Temporary Construction Entrance (3.02)- A temporary construction entrance shall be installed at the site entrance as
shown on the erosion and sediment control plan.
3. Road Stabilization (3.03) - Access roads, parking areas and other on -site vehicle transportation routes shall be
stabilized with stone immediately after grading.
4. Silt Fence Barrier (3.05) - Silt fence barriers will be installed to filter runoff from sheet flow as shown on the erosion
and sediment control plan.
5. Super Silt Fence Barrier - Wire -reinforced silt fence barrier will be installed to filter runoff from sheet flow as shown
on the erosion and sediment control plan.
6. Inlet Protection (3.07) — Inlet protection will be installed at all proposed storm drain inlets installed prior to final
stabilization of the site.
7. Culvert Inlet Protection (3.08) — Sediment filter installed to prevent sediment from entering, accumulation in or being
transferred by a culvert.
8. Temporary Diversion Dike (3.09) — A system of diversion dikes to direct flow into the sediment trap will be installed
as shown on the erosion and sediment control plans.
9. Clean- Water Diversion Dikes — A system of diversion dikes to direct the flow of clean offsite water away from the
site will be installed as shown on the erosion and sediment control plan.
10. Temporary Sediment Trap (3.13) — A temporary sediment trap is to be constructed in conjunction with culvert inlet
protection. Calculations for the sediment trap are shown with the erosion and sediment control details.
11. Temporary Sediment Basin (3.14) — A temporary sediment basin is to be constructed as shown on the erosion and
sediment control plan. Calculations for the sediment basin are shown with the erosion and sediment control detail for
the sediment basin.
12. Stormwater Conveyance channel (3.17) — A series of channels shall be constructed to provide for the conveyance of
concentrated runoff to a receiving channel without damage from erosion. Typical ditch sections and calculations area
shown on the plan.
13. Outlet Protection (3.18) — Outlet protection will be installed at the end of all storm sewer pipes. Calculations for the
outlet protection are shown with the erosion and sediment control details. The riprap should be checked periodically
to ensure scouring is not occurring beneath fabric underlining of the riprap layer.
14. Check Dam (3.20) — Rock check dams will be installed in the proposed ditches to reduce the velocity of concentrated
flows which will help in the establishment of the grass lining. After the upslope area is stabilized, the check dams
may be removed and properly disposed in accordance with VECSH Regulations.
15. Level Spreader (3.21) — Level spreader will be installed at the end of diversions or dikes to convert channelized flow
to sheet flow to avoid causing erosion.
16. Turbidity Curtain (3.27) — A floating geotextile material which minimizes sediment transport from a disturbed area
adjacent to or within a body of water.
17. Surface Roughening (3.29) — All areas with a grade steeper than 3:1 shall be stair -step graded or grooved (plate 3,29-
4) to aid in grass establishment, increase infiltration, and to slow runoff volumes
Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County
18. 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.
19. 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.
20. Permanent Seeding (3.32) — Areas brought to final grade or those construction areas that will remain dormant for a
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.
21. Mulch (3.35) — Plant residues or other suitable materials shall be applied to disturbed surfaces to prevent erosion and
reduce overland flow velocities. This practice should be applied to all seeding operations, other planter materials
which do not provide adequate soil protection by themselves, and bare areas which cannot be seeded due to the season
but which still need protection to prevent soil loss. 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.
22. Erosion Control Blankets (3.36) — Erosion control blankets in conjunction with permanent seeding will be installed on
all slope's steeper than 3:1 following grading. Erosion control blankets will also be installed in ditches where potential
erosive velocities may exist as determined by engineering calculations. This will protect from rill and gully erosion.
23. Tree Protection (3.38) — The tree fence barrier will be installed to protect the trees outside of the limits of disturbance
as shown on the erosion and sediment control plan.
24. 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.

Section 5. Stormwater Management Plan
(Provide a reduced I Ix17 copy of the latest Stormwater management plan. Do not reference only.)
The development of S.L. Williamson Asphalt Plant will occur in two phases or separate stages of construction. The completed
project will utilize non -concentrated discharge to facilitate channel and flood protection. Stormwater Runoff will be collected
and conveyed via sheet flow. Water quality provision are proposed via offsite nutrient credit purchase.
Regarding Water Quality Analysis:
9VAC25-870-63, water quality design criteria requirements.
offsite nutrient credit purchase.
The water quality portions of this plan will be satisfied using
Regarding Water Quantity Analysis:
Compliance of 9VAC25-870-66-B (Channel Protection): In accordance with channel protection section B of 9VAC25-870-66
of Virginia Law, no concentrated flows are designed to leave the site therefore 870-66-B is not applicable.
Compliance of 9VAC-870-66.0 (Flood Protection):
In reference to flood protection section C.1, no concentrated flows are designed to leave the site therefore 870-66-C is not
applicable.
Compliance of 9VAC-870-66. D (Sheet Flows):
In reference to increased volumes of sheet flows, section D. This site is bordered by, and discharges to a mapped flood plain.
Landcover and use from this project will be fundamentally identical to the current use and landcover therefore as runoff is
relatively unchanged implications to downstream channels and area flood plains are expected to be unchanged as well.

**Spill report form and procedure can be found in Section 13. Additional Information and Logs**
F. Pollution Prevention Awareness
Material Management Practices/Spill Prevention:
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. Weekly tailgate training
meetings are advised to ensure that as the site evolves and changes employees are up to date on all PPP
practices. A training log to document these meetings can be found in Section 13. Additional Information and
Logs.
(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
Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County
Hazardous Products:
These practices are used to reduce the risk associated with hazardous materials. Hazardous waste to include oil
filters, petroleum products, paint, curing compounds and equipment maintenance fluids.
1. Products will be kept in original containers unless they are not re -sealable.
2. Products will be stored in structurally sound and sealed containers and segregated from other non -waste
materials.
3. Original specimen labels and materials safety data sheets will be kept on file; they contain important product
information.
4. If surplus product must be disposed of, manufacturers and/or local and State recommended methods for
proper disposal will be followed.
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".
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 ensure 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, Curing Compounds, Soaps, Solvents, and Detergents:
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. Discharges of soaps,
solvents and detergents are prohibited.
(d) Concrete Trucks and Wash Water from Construction Materials and Vehicles:
Concrete trucks will only wash out or discharge surplus concrete or drum wash water at approved locations in
accordance with State and local regulations. Wash water must be directed into a leak proof container or leak -
Issued — 10/2014 Stormwater Pollution Prevention Plan (SWPPP) Albemarle County
proof settling basin that is properly designed. The liquid and hardened concrete must then be handled and
disposed of properly and is not to be discharged. Washout areas are identified on the SWPPP/PPP Reference
Drawing included with the "Final Construction Plans". An EPA concrete washout factsheet is provided in
Appendix I. Water from vehicle wash stations (if needed) is to be directed to the nearest trap as shown on the
approved erosion and sediment control plan before discharged.
(e) Solid Waste:
All waste materials will be collected and disposed of into a metal trash dumpster in the staging area.
Dumpsters will have a secure watertight lid, be placed away from stormwater conveyances and
drains, and meet all local and state solid -waste management regulations. Only trash and construction
debris from the site will be deposited in the dumpsters. All personnel will be instructed, during
tailgate training sessions, regarding the correct procedure for disposal of trash and construction
debris. Notices that state these practices will be posted in the office trailer and the individual who
manages day-to-day site operations will be responsible for seeing that these practices are followed
(f) Sanitary Waste:
Portable lavatories are located on -site and are serviced on a regular basis by a contractor. They will
be located in up -land areas away from direct contact with surface waters. Any spills occurring during
servicing will be cleaned up immediately, including any contaminated soils, and disposed of
according to all federal, state, and local regulations.
(g) Minimization of Exposure to Precipitation and Storm Events
In the event that precipitation is predicted onsite, construction activity operator to ensure that all building
materials, building products, construction wastes, trash, landscape materials, fertilizers, pesticides, detergents,
sanitary waste and other materials present onsite is protected from the runoff by the sure of covering tarps that
securely fastened to eliminate blow off.

wasteload allocation, and exceptional waters.
Name of Receiving Waters:
North Fork Hardware River, JM46 (020802031201)
Measures for applicable TMDL:
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 LB.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
stone event occurs when there are more than 24 hours between business days, the inspection shall be conducted on

approved stormwater management plan is not required. In lieu of an approved stormwater
management plan, the SWPPP shall include a description of, and all necessary
calculations supporting, all post -construction stormwater management measures that will
be installed prior to the completion of the construction process to control pollutants in
stormwater discharges after construction operations have been completed. Structural
measures should be placed on upland soils to the degree possible. Such measures must
be designed and installed in accordance with applicable VESCP authority, VSMP
authority, state, and federal requirements, and any necessary permits must be obtained.
Pollution prevention plan. A pollution prevention plan that addresses potential pollutant -
generating activities that may reasonably be expected to affect the quality of stormwater
discharges from the construction activity, including any support activity. The pollution
prevention plan shall:
a. Identify the potential pollutant -generating activities and the pollutant that is expected to be
exposed to stormwater;
Page 9 of 26
b. Describe the location where the potential pollutant -generating activities will occur, or if
identified on the site plan, reference the site plan;
c. Identify all nonstormwater discharges, as authorized in Part I E of this general permit, that
are or will be commingled with stormwater discharges from the construction activity,
including any applicable support activity;
d. Identify the person responsible for implementing the pollution prevention practice or
practices for each pollutant -generating activity (if other than the person listed as the
qualified personnel);
e. Describe the pollution prevention practices and procedures that will be implemented to:
(1) Prevent and respond to leaks, spills, and other releases including (i) procedures for
expeditiously stopping, containing, and cleaning up spills, leaks, and other releases;
and (ii) procedures for reporting leaks, spills, and other releases in accordance with
Part III G;
(2) Prevent the discharge of spilled and leaked fuels and chemicals from vehicle fueling
and maintenance activities (e.g., providing secondary containment such as spill
berms, decks, spill containment pallets, providing cover where appropriate, and having
spill kits readily available);
(3) 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 (e.g., providing (i) cover (e.g., plastic sheeting or temporary roofs)
to prevent contact with stormwater; (ii) collection and proper disposal in a manner to
prevent contact with stormwater; and (iii) a similarly effective means designed to
prevent discharge of these pollutants);
(4) Minimize the discharge of pollutants from vehicle and equipment washing, wheel wash
water, and other types of washing (e.g., locating activities away from surface waters
and stormwater inlets or conveyance and directing wash waters to sediment basins or
traps, using filtration devices such as filter bags or sand filters, or using similarly
effective controls);
(5) Direct concrete wash water into a leak -proof container or leak -proof settling basin. The
container or basin shall be 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. Liquid concrete
wastes shall be removed and disposed of in a manner consistent with the handling of
other construction wash waters and shall not be discharged to surface waters;
(6) Minimize the discharge of pollutants from storage, handling, and disposal of
construction products, materials, and wastes including (i) building products such as
asphalt sealants, copper flashing, roofing materials, adhesives, and concrete
admixtures; (ii) pesticides, herbicides, insecticides, fertilizers, and landscape
Page 10 of 26

scrap construction materials, masonry products, timber, pipe and electrical cuttings,
plastics, Styrofoam, concrete, and other trash or building materials;
(7) Prevent the discharge of fuels, oils, and other petroleum products, hazardous or toxic
wastes, waste concrete, and sanitary wastes;
(8) Address any other discharge from the potential pollutant -generating activities not
addressed above;
(9) Minimize the exposure of waste materials to precipitation by closing or covering waste
containers during precipitation events and at the end of the business day, or
implementing other similarly effective practices. Minimization of exposure is not
required in cases where the exposure to precipitation will not result in a discharge of
pollutants; and
f. Describe procedures for providing pollution prevention awareness of all applicable wastes,
including any wash water, disposal practices, and applicable disposal locations of such
wastes, to personnel in order to comply with the conditions of this general permit. The
operator shall implement the procedures described in the SWPPP.
SWPPP requirements for discharges to nutrient and sediment impaired waters. For
discharges to surface waters (i) identified as impaired in the 2016 § 305(b)/303(d) Water
Quality Assessment Integrated Report or (ii) with an applicable TMDL wasteload allocation
established and approved prior to the term of this general permit for sediment for a sediment -

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

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

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.

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.

Procedure for Spills of Non -Reportable Quantities
Most spills can be cleaned up following manufacturer specifications. Absorbent/oil dry, sealable containers, plastic bag and
shovels/brooms are suggested minimum spill response items that should be available at this location.
1) Check for hazards (flammable material, noxious fumes, cause of spill)- if flammable liquid, turn off engines and
nearby electrical equipment. If serious hazards are present, leave the area and call 911.
2) Make sure the spill area is safe to enter and that it does not pose an immediate threat to health or safety of any person.
3) Stop the spill source.
4) Call co-workers and supervisor for assistance and to make them aware of the spill and potential dangers.
5) If possible, stop spill from entering drains (use absorbent or other material as necessary)
6) Stop spill from spreading (use absorbent or other material)
7) If spill material has entered a storm sewer; contact locality's storm sewer water department and locality's VSMP
inspector.
8) Clean up spilled material and do not flush area with water.
9) Properly dispose of cleaning materials and used absorbent material according to manufacturer specifications.
