County Code section 17 -410 and Virginia Code §62.1- 44.15:34 requires the VSMP authority to
act on any VSMP permit by issuing a project approval or denial. This project is APPROVED.
The VSMP application content requirements can be found in County Code section 17 -401.
A. Stormwater Pollution Prevention Plan ( SWPPP)
The SWPPP content requirements can be found in County Code section 17 -405. A SWPPP must
contain (1) a PPP, (2) an ESOP, (3) a SWMP, and (4) any TMDL measures necessary.

prepare estimates and check parcel and easement information based on the approved plans. The County's
Management Analyst will prepare bond agreement forms, which will need to be completed by the owner
and submitted along with cash, certificates or sureties for the amounts specified. The agreements will need
to be approved and signed by the County Attorney and County Engineer. This may take 2 -4 weeks to
obtain all the correct signatures and forms.
Stormwater Management Facilities Maintenance agreements will also need to be completed and recorded.
The County's Management Analyst or other staff will prepare the forms and check for ownership and
signature information. The completed forms will need to be submitted along with court recording fees.
After bonding and agreements are complete, county staff will need to enter project information in a DEQ
database for state application processing. DEQ will review the application information based on local
VSMP authority approval. At this time, the DEQ portion of the application fees will need to be paid
directly to the state. For fastest processing, this is done electronically with the emails provided on the
application. DEQ should notify applicants with instructions on how to pay fees. When DEQ approves the
application, they will issue a permit coverage letter. This should be copied to the county.
After DEQ coverage is issued, via the coverage letter, the County can hold a pre - construction conference.
Applicants will need to complete the request for a pre - construction conference form, and pay the remainder
of the application fee. The form identifies the contractor and responsible land disturber, and the fee
remaining to be paid. This will be checked by county staff, and upon approval, a pre - construction
conference will be scheduled with the County inspector. At the pre - construction conference, should
everything proceed satisfactorily, a joint VSMP and grading permit will be issued by the County so that
work may begin.
County forms can be found on the county website forms center under engineering;

County Code section 17 -410 and Virginia Code §62.1- 44.15:34 requires the VSMP authority to
act on any VSMP permit by issuing a project approval or denial. This project is denied. The
rationale is given in the comments below. The application may be resubmitted for approval if all
of the items below are satisfactorily addressed. The VSMP application content requirements can
be found in County Code section 17 -401.
A. Stormwater Pollution Prevention Plan (SWPPP)
The SWPPP content requirements can be found in County Code section 17 -405. A SWPPP must
contain (1) a PPP, (2) an ESOP, (3) a SWMP, and (4) any TMDL measures necessary.
Please have the owner fill out the required forms for the SWPPP for plan approval. The owner is
the Operator until the plan is approved, the "Operator" can be transferred to additional personnel at
anytime during the duration of the project, see transfer forms in SWPPP. The link to the
Albemarle County preferred SWPPP form is:

B. Pollution Prevention Plan (PPP)
The PPP content requirements can be found in County Code section 17 -404.
1. Appears adequately addressed at this time.
C. Stormwater Management Plan (SWMP)
VSMP Regulation 9VAC25- 870 -108 requires the VSMP authority to approve or disapprove a
SWMP. This plan is disapproved, and the reasons are provided in the comments below. The
stormwater management plan content requirements can be found in County Code section 17 -403.
VRRM updated spread sheet appears to be for 11.76 acres of disturbance. The VRRM
spreadsheet should be for the proposed new construction/ disturbed area. The drainage area to the
water quality structure appears to be just under 2 acres. Please Correct the VRRM Spreadsheet
and show the drainage areas on the plan for conformation.

D. Erosion and Sediment Control Plan (ESCP)
Virginia Code §62.1- 44.15:55 requires the VESCP authority to approve or disapprove an ESCP.
This plan is approved, and the reasons are provided in the comments below. The erosion control
plan content requirements can be found in County Code section 17 -402.
The Variance for the Modified Mud Traps is approved for this project due to the confined space
on site and proximity to the flood plain.
The VSMP permit application and all plans may be resubmitted for approval when all comments have
been satisfactorily addressed. For re- submittals please provide 2 copies of the complete permit package
with a completed application form.
Engineering plan review staff are available from 2 -4 PM on Thursdays, should you require a meeting to
discuss this review.

RE: Coverage under the VPDES Construction General Permit(VAR10)
General Permit No. VAR10G967
South Rivanna Water Treatment Plant
INDUSTRIAL
Albemarle
Dear Permittee:
DEQ has reviewed your Registration Statement received on August 12, 2014 and determined that the
proposed land-disturbing activity is covered under the General VPDES Permit for Discharges of Stormwater from
Construction Activities (VAR10). The effective date of your coverage under this general permit is July 1, 2014 or
the date of this letter,whichever is later.
A copy of the general permit can be obtained from DEQ's webpage at the following location:
http://www.dea.virginia.gov/Portals/0/DEQ/Water/Publications/CGP2014.pdf.
The general permit contains the applicable Stormwater Pollution Prevention Plan (SWPPP) requirements and
other conditions of coverage. Please print the general permit and read it carefully as you will be responsible for
compliance with all permit conditions.
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 II.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 management 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(5) 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
• Representative inspections used by utility line installation, pipeline construction, or other similar linear
construction activities shall inspect all outfalls.
The general permit will expire on June 30, 2019. The conditions of the general permit require that you submit
a new registration statement at least 90 days prior to that date if you wish to continue coverage under the general
permit, unless permission for a later date has been granted by the Board. Permission cannot be granted to
submit the registration statement after the expiration date of the general permit.
If you have any questions about this permit, please contact the DEQ Office of Stormwater Management at
ConstructionGP edea.virginia.gov.
Sincerely,
•
