A. The stormwater conveyance system conveys the post - development peak flow rate from the two -year 24 -hour storm event without causing erosion of
the system (V2 must be shown to be non - erosive)
B T he development project, in combination with other stormwater runoff, is consistent with the design parameters of the restored stormwater
conveyance and the restored stormwater conveyance system is functioning as designed
C. The discharge from the development 'satisfies the Energy Balance requirement
(Qdeveloped x RVdeveloped) 5 IF x (Qpre - developed x RVpre- developed)
where:
Qdeveloped = the peak flow rate of runoff from the developed site
RVdeveloped = the volume of runoff from the site based on developed conditions
IF = an improvement factor (0.8 for sites > 1 acre, 0.9 for sites <- 1 acre)
Qpre - developed = the peak flow rate of runoff from the pre - developed site
RVpne developed = the volume of runoff from the site based on pre - developed conditions

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

POTENTIAL POLLUTANT SOURCES
The following sources of potential pollutants must be addressed in the Pollution
Prevention Plan. Various controls and /or measures designed to prevent and /or
minimize pollutants in stormwater discharges from the project site must be applied to
the sources found on the site. Additional information concerning the following controls
and /or measures may be found in the SWPPP. Deviations from the location criteria
may be approved by the Henrico County Environmental Inspector
LEAKS, SPILLS, AND OTHER RELEASES
• The operator(s) shall ensure procedures are in place to prevent and respond to all
leaks, spills and other releases of pollutants.
• The operator(s) shall ensure all leaks, spills and other releases of pollutant are
contained and cleaned immediately upon discovery Any contaminated materials
are to be disposed in accordance with federal, state, and /or local requirements
• The operator(s) shall ensure spill containment kits containing appropriate materials
(e.g., absorbent material and pads, brooms, gloves, sand, etc ) are available at
appropriate locations, including, but not limited to designated areas for vehicle and
equipment maintenance, vehicle and equipment fueling, storage and disposal of
construction materials, products, and waste, and storage and disposal of hazardous
and toxic materials; and sanitary waste facilities.

OPERATOR INSPECTIONS
The operator(s) identified below shall provide for inspections of the permitted land -
disturbing activities by the qualified personnel identified below. The inspections will be
conducted (select one the following options)
❑ at, least once every. four (4) business days, or
at least once every five (5)'business -days and no later-than 48 hours following
anY, measurable storm event
Where areas are in a stabilized condition or runoff is unlikely due to winter conditions,
the inspection frequency may be reduced to once every 30 days while these conditions
exist Otherwise, the operator(s) shall resume the regular inspection frequency
identified above
The operator(s) shall provide for inspections of the permitted land - disturbing activity to
ensure implementation and continued maintenance of all requirements of the

binder The qualified personnel are encouraged to use the Operator Inspection form
provided in the SWPPP binder to document the required inspections. If inspections are
conducted once every five (5) business days and no later than 48 hours following any

As the Operator(s) or Delegated Authority, I /we understand that prior to initiating land
disturbance, the potential pollutant sources, appropriate control measures, and all
responsible parties (operator, qualified inspection personnel, contractors, etc ) required
as a condition of the General Construction Permit (GCP) and the Stormwater Pollution
Prevention Plan (SWPPP) must be identified. I also understand this information must
be updated as necessary throughout all phases of construction until the GCP is
terminated
Furthermore,
I /we certify under penalty of law that I /we have read and understand all requirements of
the SWPPP (erosion and sediment control plan, stormwater management plan, pollution
prevention plan, TMDL provisions, administrative requirements, etc.) and GCP and that
the information herein is, to the best of my knowledge and belief, true, accurate, and
complete. I am aware that there are significant penalties for submitting false
information, including the possibility of fine or imprisonment for knowing violations

I /we shall take all reasonable steps to minimize or prevent any discharge in violation of
the SWPPP and /or GCP.
I /we understand that if it determined by the Department of Environmental Quality (DEQ)
in consultation with the State Water Control Board at any time that stormwater
discharges are causing, have reasonable potential to cause, or contribute to and
excursion above any applicable water quality standard, the DEQ may, in consultation
with the Administrator, take appropriate enforcement action and require:
a Modification of control measures to adequately address water quality
concerns,
b Submission of valid and verifiable data and information that are
representative of ambient conditions and indicate that the receiving water is
attaining water quality standards, or
c Cessation of discharges of pollutants from construction activity and submit an
individual permit application according to 4VAC25- 870 -410
