4. Protect Slopes:
Erosion control blankets and matting, tackifiers, etc. are propsed for the drainage swales and
for the riverbank cut slope at the proposed boat slide.
BMP Description: Soil Stabilization Blankets & Matting
Geotextile erosion control blankets will be used to provide stabilization where necessary.
The blanket will cover the areas shown on the plans. The blanket will be installed
by digging a small trench on the upside of the slope, 12 inches wide by 6 inches deep, and
stapling the leading edge of the blanket in the trench. The blanket will be rolled down the
slope slowly to maintain soil contact and stapled in 12-inch intervals. If the blanket cannot
cover the entire slope, the blankets will be overlapped (minimum of 2 inches) and stapled
at the overlapped edge. The erosion control blanket will always be installed according to
manufacturer's instructions andspecifications.
Installation Schedule:
The erosion control blankets will be installed once the
soil has reached final grade.
Maintenance and Inspection:
The erosion control blanket will be inspected weekly and
immediately after storm events to determine if cracks,
tears, or breaches have formed in the fabric; if so, the
blanket will be repaired or replaced immediately. Good
contact with the soil must be maintained and erosion
should not occur under the blanket. Any areas where the
blanket is not in close contact with the ground will be

driven securely into the ground: a minimum of 18 to 20 inches deep. The silt fence will
be fastened securely to the wooden posts with wire ties spaced every 24 inches at the top,
mid -section, and bottom of the wooden post. The bottom edge of the silt fence will be
extended across the bottom of the trench and the trench will be backfilled and compacted
to prevent stormwater and sediment from discharging underneath the silt fence.
Installation Schedule:
The silt fence will be installed before construction begins
at the site and silt fence locations are illustrated on the
plan Section 4).
Maintenance and Inspection:
Silt fences will be inspected weekly and immediately
after storm events to ensure it is intact and that there are
no gaps where the fence meets the ground or tears along
the length of the fence. If gaps or tears are found during
the inspection, the fabric will be repaired or replaced
immediately. Accumulated sediment will be removed
from the fence base if it reaches one-third the height of
the silt fence and hauled off -site for disposal. If
accumulated sediment is creating noticeable strain on the
fabric and the fence might fail from a sudden storm
event, the sediment will be removed more frequently.
Before the fence is removed from the project area, the
sediment will be removed. The anticipated life span of
the silt fence is 6 months and will likely need to be
replaced after this period.
Responsible Staff:
Responsible Land Disturber see page 2
Design Specifications
1. The silt fence will be constructed long enough to extend across the expected flow path.
2. The support posts will be a minimum of 4.5 feet and driven a minimum of 18 to 20 inches in
the ground. Posts will be spaced a maximum of 6 feet apart. Fabric will be securely fastened to
posts with half -inch staples or 16-gauge wire ties spaced a maximum of 6 inches.
3. A 12-inch trench will be excavated along the uphill side of the silt fence posts. The bottom
edge of the fabric will extend across the bottom of the trench. The trench will be backfilled to 4
inches above ground and compacted to bury and secure the bottom of the filter fabric.

7. Retain Sediment On -Site and Control Dewatering Practices:
Describe sediment control practices (i.e., sediment trap or sediment basin), including design
specifications and details (volume, dimensions, outlet structure) that will be implemented at the
construction site to retain sediments on -site. Describe dewatering practices that will be
implemented if water must be removed from an area so that construction activity can continue.
BMP Description: Temporary Sediment Trap
Not Required for this projet.
Installation Schedule:
NA
Maintenance and Inspection:
N. A. The trap will be inspected weekly and after storm
events. The trap will be checked for signs of erosion,
seepage, and structural damage. The outlet will be
checked for any damage or obstructions and any damage
present will be repaired and obstructions removed.
Sediment will be removed and the trap restored to its
original dimensions when the sediment has accumulated
to one-half the design depth of the trap. The removed
sediments will be hauled off -site for disposal at the
Landfill.
Responsible Staff:
Responsible Land Disturber see page 2
8. Establish Stabilized Construction Exits:
Describe location(s) of vehicle entrance(s) and exit(s), procedures to remove accumulated
sediment off -site (i.e., vehicle tracking), and stabilization practices (i.e., stone pads and/or wash
racks) to minimize off -site vehicle tracking of sediments and discharges to stormwater.
BMP Description: Temporary Stone Construction Entrance
A stone entrance shall be constructed utilizing existing driveways, as identified on the site
map, to prevent off -site transport of sediment by construction vehicles. The stone entrance
will be at least 70 feet long and a minimum of 10 feet wide.
This stone area shall be used for washing sediment from vehicles exiting the site. Where
sediment is transported onto a public road surface, the road shall be cleaned thoroughly 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. See sheet C-110 & C-112 for location and sheet
Installation Schedule: The stabilized exits will be installed before construction
begins and shall be adjacent to Scottsville Road (Route
Stormwater Pollution Prevention Plan (SWPPP)
Brook Hill River Park - Phase 1 River Access
20) as shown on the Erosion & Sediment Control plan
C-110 & C-112 .
Maintenance and Inspection:
The exit will be inspected weekly and after storm events
or heavy use. The exit will be maintained in a condition
that will prevent tracking or flowing of sediment onto
Scottsville Road. All sediment tracked, spilled, dropped,
or washed onto Scottsville Road will be swept up
immediately and hauled off -site for disposal at the
landfill. Broken road pavement as a result of
construction activities on roadways immediately
adjacent to the project site will be repaired immediately.
Alternate Method:
The County inspector may, at their discretion, require
the use of a paved construction entrance as an alternate
to the stone construction entrance. For details see E&SC
plan details on sheet C-120.
Responsible Staff:
Responsible Land Disturber see page 2
9. Additional BMPs:
Describe additional BMPs that may not fit into the above categories.
BMP Description: Surface Roughening
This erosion and sedimentation control measure involves creating horizontal depressions
on slopes or leaving slopes in a roughened condition by not fine -grading them. This is
done to aid in the establishment of vegetative cover or seed, to reduce runoff velocity and
increase infiltration, and to reduce erosion and provide for sediment trapping. Stair -step
grades or groove -cut slopes will be used for gradients steeper than 3:1. Stair -step grading
on any erodible material that is soft enough to be ripped with a bulldozer. Also, it is well
suited for slopes consisting of soft rock with some subsoil. Make the vertical cut distance
less than the horizontal distance, and slope the horizontal portion of the step slightly
toward the vertical wall. Keep individual vertical cuts less than 2 feet deep in soft
materials and less than 3 feet d ep in rocky materials.
Installation Schedule:
Roughening shall occur after vegetation has been
removed from the slope after grading.
Maintenance and Inspection:
The surface roughening will be inspected to ensure that
the proper sloping is achieved after stair -stepping
concludes.

Stonnwater Pollution Prevention Plan (SWPPP)
Brook Hill River Park— Phase] River Access
SECTIONS: STORMWATER MANAGEMENT PLAN
Stormwater Manaeement Narrative: Water Ouanti
Pre -Construction Site Conditions:
A drainage area totaling 7.15 acres flows through the point of interest before entering the Rivanna River.
This flow is a mix of on -site and off -site drainage. The majority of off -site drainage flowing through the
point of interest totals 5.42 acres and contains a mix of forested site condition and roadway drainage. The
majority of off -site drainage conveys across Rio Mills Road onto VDOT maintained Right -of -Way via a
24" concrete pipe. This Right -of -Way is located adjacent to the project site. The off -site drainage then
converges with other off -site overland flow with a drainage area totaling 0.56 acres. All of this off -site
drainage then enters an existing drainage ditch that runs along the length of the Right -of -Way property
before entering a 30" concrete pipe and ultimately the Rivanna River.
On -site drainage totaling 0.39 acres converges with the off -site drainage, described above, prior to
conveying through a 30" concrete pipe located within the U.S. Route 29 Right -of -Way. This drainage then
enters the Rivanna River.
The remaining on -site surface drainage within the project area conveys via overland sheet flaw directly
into the Rivanna River located on the southern portion at the property. This drainage area is 0.93 acres in
total and includes 0.24 acres of impervious surface from a combination of road drainage and an existing
gravel parking lat.
Post -Construction Site Conditions:
Post -construction off -site drainage flows are similar to pre -construction flow patterns and will remain
unchanged with this site plan.
A proposed new drainage ditch along the eastern edge of the project conveys stormwater from a portion
of the existing Rio Mills roadway, a portion of the proposed gravel road, and on -site overland flow to the
point where it converges with off -site drainage. Once the flows converge, they convey through the
existing 30" concrete pipe located within the Right -of -Way. A drainage area totaling 0.73 acres of mixed
pervious and impervious surface will flow through the proposed drainage ditch. The proposed drainage
ditch will widen and contain two river rock check dams as shown on the plan to slow down and settle
stormwater prior to exiting the site.
Method of Analysis:
The point of interest for our analysis was chosen as the point where all drainage areas from the project
will converge. This paint allows for the quantification of stormwater exiting the biofilter and the water
exiting the existing 30" concrete pipe. This is the point where all off -site and on -site drainage will
converge prior to entering the Rivanna River.
Adjacent property information and VDOT US Route 29 road plan As -Built documents were utilized to
develop the limits of the off -site drainage that enters the existing 30" concrete pipe. Pre -construction and
past -construction flows were modeled using HydroCAD software to demonstrate that this project meets
energy balance and state regulations. The modelling software projected flow rates were then analyzed to
confirm that energy balance requirements will be achieved with the proposed site improvements.
Summary
Stonnwater Pollution Prevention Plan (SWPPP)
Brook Hill River Park— Phase] River Access
Pre -construction peak flows were calculated to be 5.61 cfs at the point of interest. The energy balance
equation allows for a post -construction maximum allowable flaw rate of 5.25 cfs. The proposed plan
achieves a peak flow rate of 5.18 cfs in the past -construction condition.
The energy balance at the point of interest for the 1-YR, 24-hr storm is being met with the proposed site
improvements. This satisfies VSMP regulations under Part II B, Water Quantity (9VAC25-870-66.B.3.a.).
Stormwater Manaaement Narrative: Water Quality
Pre -Construction Site Conditions:
There are no existing stormwater quality measures located on -site.
Post -Construction Site Conditions:
A biofilter will be constructed to treat and improve on -site stormwater runoff prior to entering the
Rivanna River. The biofilter will offset the impact of all proposed site improvements via nutrient removal.
The drainage area entering the biofilter totals 0.59 acres and is a mix of impervious and pervious surfaces.
The biofilter will be located within the gravel parking lot circulation driveway. The proposed level 2
biofilter has a surface area of 800 sf Stormwater flowing into the biofilter will convey through a check
dam then through a pre-treatment cell prior to entering the biofilter.
Method of Analysis:
Impervious and pervious surfaces far pre -construction and past -construction site conditions were
quantified and entered into the DEQ VRRM spreadsheet. This allowed us to ensure that state required
stormwater quality benchmarks were being met with the proposed site improvements.
Summary:
A proposed biofilter will be utilized to meet water quality requirements and to satisfy VSMP regulations
under Part II B, Water Quality (9VAC25-870-65). The DEQ VRRM spreadsheet summary can be found
on sheet C-401 of the plan set. The proposed biofilter is designed to remove 0.76 lb/yr of total phosphorus
nutrient loads. This exceeds the minimum required amount of minimal TP removal by 0.06 lb/yr.

6.3 Endangered Species Certification
Project Information:
Are endangered or threatened species and critical habitats on or near the project area?
® Yes ❑ No
Describe how this determination was made
A study of the Virginia Department of Game and inland fisheries website was made in August of
2021 to determine if endangered or critical habitats reported or potential habitats could be
located within a three-mile radius of the site. The website suggested that there could potentially
be as many as twelve endangered or threatened species near the site. The website that was used
to make this determination is:
http://vafwis.org/fwis/index.asp
See table 2 below for potential specific species in the surrounding area within a three-mile
radius of the site.

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

an individual or position having overall responsibility for environmental matters for the
operator. (A duly authorized representative may thus be either a named individual or any
individual occupying a named position); and
c. The signed and dated written authorization is included in the SWPPP. A copy shall be
provided to the department and VSMP authority, if requested.
3. Changes to authorization. If an authorization under Part III K 2 is no longer accurate because
a different individual or position has responsibility for the overall operation of the construction
activity, a new authorization satisfying the requirements of Part III K 2 shall be submitted to
the VSMP authority as the administering entity for the board prior to or together with any
reports or information to be signed by an authorized representative.
4. Certification. Any person signing a document under Part III K 1 or 2 shall make the following
certification:
"I certify under penalty of law that I have read and understand this document and that this
document and all attachments were prepared in accordance with a system designed to assure
that qualified personnel properly gathered and evaluated the information submitted. Based on
my inquiry of the person or persons who manage the system, or those persons directly
responsible for gathering the information, the information submitted is, to the best of my
knowledge and belief, true, accurate, and complete. I am aware that there are significant
Page 23 of 26
penalties for submitting false information, including the possibility of fine and imprisonment for
knowing violations."
L. Duty to comply. The operator shall comply with all conditions of this general permit. Any state
permit noncompliance constitutes a violation of the Virginia Stormwater Management Act and the
Clean Water Act, except that noncompliance with certain provisions of this general permit may
constitute a violation of the Virginia Stormwater Management Act but not the Clean Water Act.
Permit noncompliance is grounds for enforcement action; for state permit coverage, termination,
revocation and reissuance, or modification; or denial of a state permit renewal application.
The operator shall comply with effluent standards or prohibitions established under § 307(a)
of the Clean Water Act for toxic pollutants within the time provided in the regulations that establish
these standards or prohibitions or standards for sewage sludge use or disposal, even if this
general permit has not yet been modified to incorporate the requirement.
M. Duty to reapply. If the operator wishes to continue an activity regulated by this general permit
after the expiration date of this general permit, the operator shall submit a new registration
statement at least 60 days before the expiration date of the existing general permit, unless
permission for a later date has been granted by the board. The board shall not grant permission
for registration statements to be submitted later than the expiration date of the existing general
permit.
N. Effect of a state permit. This general permit does not convey any property rights in either real
or personal property or any exclusive privileges, nor does it authorize any injury to private property
or invasion of personal rights, or any infringement of federal, state or local law or regulations.
O. State law. Nothing in this general permit shall be construed to preclude the institution of any
legal action under, or relieve the operator from any responsibilities, liabilities, or penalties
established pursuant to any other state law or regulation or under authority preserved by § 510 of
the Clean Water Act. Except as provided in general permit conditions on "bypassing" (Part III U)
and "upset' (Part III V), nothing in this general permit shall be construed to relieve the operator
from civil and criminal penalties for noncompliance.
P. Oil and hazardous substance liability. Nothing in this general permit shall be construed to
preclude the institution of any legal action or relieve the operator from any responsibilities,
liabilities, or penalties to which the operator is or may be subject under §§ 62.1-44.34:14 through
62.1-44.34:23 of the State Water Control Law or § 311 of the Clean Water Act.
Q. Proper operation and maintenance. The operator shall at all times properly operate and
maintain all facilities and systems of treatment and control (and related appurtenances), which
are installed or used by the operator to achieve compliance with the conditions of this general
permit. Proper operation and maintenance also includes effective plant performance, adequate
funding, adequate staffing, and adequate laboratory and process controls, including appropriate
quality assurance procedures. This provision requires the operation of back-up or auxiliary
facilities or similar systems, which are installed by the operator only when the operation is
necessary to achieve compliance with the conditions of this general permit.
R. Disposal of solids or sludges. Solids, sludges or other pollutants removed in the course of
treatment or management of pollutants shall be disposed of in a manner so as to prevent any
pollutant from such materials from entering surface waters and in compliance with all applicable
state and federal laws and regulations.
Page 24 of 26
S. Duty to mitigate. The operator shall take all steps to minimize or prevent any discharge in
violation of this general permit that has a reasonable likelihood of adversely affecting human
health or the environment.
T. Need to halt or reduce activity not a defense. It shall not be a defense for an operator in an
enforcement action that it would have been necessary to halt or reduce the permitted activity in
order to maintain compliance with the conditions of this general permit.
U. Bypass.
1. 'Bypass," as defined in 9VAC25-870-10, means the intentional diversion of waste streams
from any portion of a treatment facility. The operator may allow any bypass to occur that does
not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to
ensure efficient operation. These bypasses are not subject to the provisions of Part III U 2 and
3.
2. Notice.
a. Anticipated bypass. If the operator knows in advance of the need for a bypass, the
operator shall submit prior notice to the department, if possible at least 10 days before the
date of the bypass.
b. Unanticipated bypass. The operator shall submit notice of an unanticipated bypass as
required in Part III I.
3. Prohibition of bypass.
a. Except as provided in Part III U 1, bypass is prohibited, and the board or department may
take enforcement action against an operator for bypass unless:
(1) Bypass was unavoidable to prevent loss of life, personal injury, or severe property
damage. Severe property damage means substantial physical damage to property,
damage to the treatment facilities that causes them to become inoperable, or
substantial and permanent loss of natural resources that can reasonably be expected
to occur in the absence of a bypass. Severe property damage does not mean
economic loss caused by delays in production;
(2) There were no feasible alternatives to the bypass, such as the use of auxiliary
treatment facilities, retention of untreated wastes, or maintenance during normal
periods of equipment downtime. This condition is not satisfied if adequate back-up
equipment should have been installed in the exercise of reasonable engineering
judgment to prevent a bypass that occurred during normal periods of equipment
downtime or preventive maintenance; and
(3) The operator submitted notices as required under Part III U 2.
b. The department may approve an anticipated bypass, after considering its adverse effects,
if the department determines that it will meet the three conditions listed in Part III U 3 a.
Page 25 of 26
V. Upset.
1. An "upset," as defined in 9VAC25-870-10, means an exceptional incident in which there is
unintentional and temporary noncompliance with technology -based state permit effluent
limitations because of factors beyond the reasonable control of the operator. An upset does
not include noncompliance to the extent caused by operational error, improperly designed
treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or
careless or improper operation.
2. An upset constitutes an affirmative defense to an action brought for noncompliance with
technology -based state permit effluent limitations if the requirements of Part III V 4 are met.
A determination made during administrative review of claims that noncompliance was caused
by upset, and before an action for noncompliance, is not a final administrative action subject
to judicial review.
3. An upset does not include noncompliance to the extent caused by operational error,
improperly designed treatment facilities, inadequate treatment facilities, lack of preventative
maintenance, or careless or improper operation.
4. An operator who wishes to establish the affirmative defense of upset shall demonstrate,
through properly signed, contemporaneous operating logs or other relevant evidence that:
a. An upset occurred and that the operator can identify the cause of the upset;
b. The permitted facility was at the time being properly operated;
c. The operator submitted notice of the upset as required in Part III I; and
d. The operator complied with any remedial measures required under Part III S.
5. In any enforcement proceeding, the operator seeking to establish the occurrence of an upset
has the burden of proof.
W. Inspection and entry. The operator shall allow the department as the board's designee, the
VSMP authority, EPA, or an authorized representative of either entity (including an authorized
contractor), upon presentation of credentials and other documents as may be required by law to:
1. Enter upon the operator's premises where a regulated facility or activity is located or
conducted, or where records shall be kept under the conditions of this general permit;
2. Have access to and copy, at reasonable times, any records that shall be kept under the
conditions of this general permit;
3. Inspect and photograph at reasonable times any facilities, equipment (including monitoring
and control equipment), practices, or operations regulated or required under this general
permit; and
4. Sample or monitor at reasonable times, for the purposes of ensuring state permit compliance
or as otherwise authorized by the Clean Water Act or the Virginia Stormwater Management
Act, any substances or parameters at any location.
Page 26 of 26
For purposes of this section, the time for inspection shall be deemed reasonable during regular
business hours, and whenever the facility is discharging. Nothing contained herein shall make an
inspection unreasonable during an emergency.
X. State permit actions. State permit coverage may be modified, revoked and reissued, or
terminated for cause. The filing of a request by the operator for a state permit modification,
revocation and reissuance, or termination, or a notification of planned changes or anticipated
noncompliance does not stay any state permit condition.
Y. Transfer of state permit coverage.
1. State permits are not transferable to any person except after notice to the department. Except
as provided in Part III Y 2, a state permit may be transferred by the operator to a new operator
only if the state permit has been modified or revoked and reissued, or a minor modification
made, to identify the new operator and incorporate such other requirements as may be
necessary under the Virginia Stormwater Management Act and the Clean Water Act.
As an alternative to transfers under Part III Y 1, this state permit may be automatically
transferred to a new operator if:
a. The current operator notifies the department at least 30 days in advance of the proposed
transfer of the title to the facility or property;
b. The notice includes a written agreement between the existing and new operators
containing a specific date for transfer of state permit responsibility, coverage, and liability
between them; and
c. The department does not notify the existing operator and the proposed new operator of
its intent to modify or revoke and reissue the state permit. If this notice is not received, the
transfer is effective on the date specified in the agreement mentioned in Part III Y 2 b.
3. For ongoing construction activity involving a change of operator, the new operator shall accept
and maintain the existing SWPPP, or prepare and implement a new SWPPP prior to taking
over operations at the site.
Z. Severability. The provisions of this general permit are severable, and if any provision of this
general permit or the application of any provision of this state permit to any circumstance, is held
invalid, the application of such provision to other circumstances and the remainder of this general
permit shall not be affected thereby.

SECTION 12: INSPECTIONS and MAINTENANCE
12.1 Inspections
Project Information:
Inspection Personnel.
The Contractor will conduct inspections and the Contractor will bear primary
responsibility for inspections of all Erosion and Sediment Control devices and pollution
prevention measures to ensure continuing effectiveness. The inspector must be
considered Qualified Personnel. Qualified personnel means a licensed professional
engineer, responsible land disturber (RLD), or other knowledgeable person who holds a
certificate of competence from the board in the area of project inspection, is enrolled in
the board's training program for project inspection or combined administrator, and
successfully completes such program within one year of enrollment.
2. Inspection Schedule and Procedures:
i. Inspections will be conducted at least once every 14 calendar days and within 48 hours
following any runoff producing storm event. Where areas have been temporarily
stabilized or runoff is unlikely due to winter conditions (e.g., the site is covered with
snow or ice, or frozen ground exists) such inspections will be conducted at least once
every month.
ii. Inspections must include all areas of the site disturbed by construction activity, off -site
areas (covered by the permit), and areas used for storage of materials that are exposed to
precipitation. Inspectors must look for evidence of, or the potential for, pollutants
entering a stormwater conveyance system. Control measures identified in the SWPPP
shall be inspected for proper installation, maintenance, and operation. Discharge
locations, where accessible, shall be inspected to ascertain whether control measures are
effective in minimizing impacts to receiving waters. Where discharge locations are
inaccessible, nearby downstream locations shall be inspected to the extent that such
inspections are practicable. Locations where vehicles enter or exit the site shall be
inspected for evidence of off -site sediment tracking.
iii. Major observations should include: the location(s) of discharges of sediment or other
pollutants from the site; amount of rainfall at the construction site since the previous
inspection; weather information and a description of any discharges occurring at the time
of inspection; location(s) of control measures that need to be maintained; location(s) of
control measures that failed to operate as designed or proved inadequate for a particular
location; and location(s) where additional control measures are needed that did not exist
at the time of inspection.
iv. All vegetative and structural erosion and sediment control practices shall be constructed
and maintained according to minimum standards and specifications of the Virginia
Erosion and Sediment Control Handbook.
Stormwater Pollution Prevention Plan (SWPPP)
Brook Hill River Park - Phase 1 River Access
V. Contractor shall prepare a report summarizing the scope of the inspection, names and
qualifications of personnel making the inspection, the dates of the inspection, major
observations relating to the implementation of the SWPPP, and actions taken in
accordance with stormwater regulations. The report shall be made and retained as part of
the SWPPP.
