Section 2. Notice of general permit coverage
(This notice is to be posted near the main entrance according to 9VAC25-880-70, Part II, section C.)
Section 3. Nature of activity
This project proposes a private school with several buildings and recreational areas on what is currently vacant land in
Albemarle County. The total area of disturbance is 8.42 acres.
The following are the proposed management strategies and detailed sequence of construction:
PHASE 1
1. Install construction entrance.
2. Install sediment traps 1, 2, and 3 with associated silt fence.
3. Install diversion dikes.
4. Call County inspector for approval of erosion and sediment control measures.
5. Upon approval, begin mass grading of site.
6. Protect soil stockpiles with silt fence and temporary seeding as necessary.
7. Transport dirt from parking lot area to field area.
PHASE 2
1. Once site is brought to grade, install storm pipe Al-A5 with connections Ma and Ma. Do not install manhole Al in
this phase, instead dig small conveyance channel for pipe Al to outlet to Sediment Trap 2.
2. Place inlet protection on all storm inlets.
3. Bring field to grade.
4. If too much water collects on eastern half of field, pump it to sediment trap 1.
5. Stabilize field area with permanent seeding.
6. Begin water & sanitary installation.
PHASE 3
1. Finish construction of buildings.
2. Install rip rap conveyance channels at outlet of pipes AO and BO prior to pipe installation.
3. Stabilize parking area with base stone.
4. Once parking area is stabilized, install manhole Al and pipes A1-A0, Al-A1x, and all roof and yard drains.
5. Once field is stabilized, install pipes A1d-Al and 134-130.
6. Keep inlet protection in place until entire site is stabilized.
7. Remove sediment traps, bringing those areas back to original grade. Apply permanent seeding and low
maintenance ground cover where slopes are 3:1 or steeper.
Section 4. Erosion and Sediment Control Plan.
Section 5. Stormwater Management Plan
The runoff for this site is collected and piped to stormwater conveyance channels lined with rip rap to outlet at two different
points of a stream leading to Moores Creek. At each point of outlet, the disturbed area from the site is less than 1% of the
contributing drainage area to that point of outlet. Therefore this site is in compliance with channel and flood protection
ordinance 9VAC25-870-66 Sections B(4) and C(3)(a).
To satisfy water quality requirements, 5.43 acres of the property will be put under a SWM conservation easement. Nutrient
credits will be purchased in the amount of 2.84 Ibs to satisfy the remaining phosphorous reduction requirement.

F. Response and reporting practices
Minimize discharges from spills and leaks. Minimize the discharge of pollutants from spills and leaks and
implement chemical spill and leak prevention and response procedures as follows. To the extent practical, do
not store oils, chemicals, or other potential contaminants on site. When storage of potential contaminants is
required, provide secondary containment, such as spill berms or spill containment pallets. These should be
located within the drainage areas to a sediment trap or sediment basin. Direct concrete wash water into a settling
basin, dispose of hardened concrete with other construction waste debris to an appropriate waste facility.
Respond to all spills, leaks and discharges as follows. Spills of oil, petroleum products, sanitary wastes, and
substances listed under 40 CFR parts 110, 117, and 302 should be cleaned up as soon as possible while
protecting worker safety. Construct an earthen dike around any spills on dirt to prevent spreading. If a spill
occurs during rainfall, cover it with a tarp or another impermeable cover to prevent contaminating runoff. Do
not bury any spills or wash them with water. Maintain a spill kits in a readily accessible location. A spill kit
shall consist of a lined drum with bags of universal sorbents in the bottom, accessible without tipping the drum,
sorbent socks above the bags, and personal protective equipment on the top. All materials used to remove the
contaminants, including any water used to rinse equipment, and all dirt removed must be treated as
contaminated. Textiles, such as from coveralls, may be sent to a certified laundry facility. Waste must be
disposed of according to the standards of The City of Charlottesville and the Commonwealth of Virginia. Store
hazardous materials and wastes in covered containers.
Report all spills, leaks and discharges as follows: All spills, leaks, and discharges shall be recorded in the
inspection logs. If construction activity results in a discharge of contaminants that may be reasonably expected
to enter surface waters, the operator shall notify the Department of Environmental Quality immediately or
within 24 hours, and shall submit a written report within five days. For significant spills that cannot be
controlled by personnel in the immediate vicinity, notify the local emergency response by dialing 911. The City
of Charlottesville must also be notified, and potentially some of the following agencies: the Fire Department,
the Public Works Department, the Coast Guard, the Highway Patrol, the County Police Department,
Department of Toxic Substances, OSHA, etc. For spills of federal reportable quantities, in conformance with
the requirements in 40 CFR parts 110, 119, and 302, the contractor should notify the National Response Center
at (800) 424-8802.
G. Pollution Prevention Awareness
The engineer, project superintendent, and contractor shall have weekly meetings to review on -site conditions
and advise contractor of potential risks that should be addressed. Contractor will be responsible for following
procedures on a daily basis and applying appropriate waste management and prevention practices to be in
compliance with the conditions of the general permit. Employees shall be informed of the danger to nature and
to human health of various chemical spills.
Section 7. Discharges to impaired waters, surface waters within an applicable TMDL
wasteload allocation, and exceptional waters.
The site discharges to the tributary from the outfall of the Ragged Mountain Reservoir to the impaired water
body Moores Creek. Causes of impairment are Benthic-Macroinvertebrate Bioassessments. Site work shall be
in compliance with the following requirements:
1. Permanent or temporary soil stabilization shall be applied to denuded areas within seven days after
final grade is reached on any portion of the site;
2. Nutrients shall be applied in accordance with manufacturer's recommendations or an approved
nutrient management plan and shall not be applied during rainfall events; and
3. In accordance with Part I B 4 and Part I B 5, inspections shall be conducted as follows:
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 48 hours following a measurable storm
event. In the event that a measurable storm event occurs when there are more than 48 hours
between business days, the inspection shall be conducted on the next business day; and
II. Representative inspections used by utility line installation, pipeline construction, or other similar
linear construction activities shall inspect all outfalls discharging to impaired waters.
