WP02019-00024 (WP0201900005 /VESCP Assig_mnent should be WP02019-00024) for Final Submittal
— A reversal from Rev. 2 comments.
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 pending non design -related
items (easements /final submittal — ref. email sent 5/13/2019 3:18 PM). Please note: ESC /SWM Plan
bonds must be posted prior to receiving a Grading Permit. See Process, below (p. 8).
A. Stormwater Pollution Prevention Plan (SWPPP) — (Rev. 3) Prior review comments addressed.

i. Show paint /stucco /solvent storage, and clean -out location, (Rev. 1) Partially
addressed. Sheet 2 Note: `This facility is for agricultural purposes, therefore, there will
be no storage of paint /stucco /solvent.' As follow-up: Please confirm there will be no on -
site storage of paint /stucco solvent during construction of proposed wine processing
building. (Rev. 2) Addressed. Metal building. No paint -solvent storage per E. Summey.

Addressed.
v. Provide /show lined concrete washout adjacent to PCE, (Rev. 1) Partially addressed.
Note states: `Actual location of concrete washout to be determined in field at time of
building pad pour. See sheet 4 for detail.' Revise Sec. 6, 11" x 17" SWPPP Exhibit to
include any on -site fuel storage, portable sanitary facilities, and indicate a preliminary
concrete wash -out location. Contractor may change initial location later. DEQ
inspections place special emphasis on this item, consistently (concrete washout). (Rev. 2)
Partially addressed. Asfollow-up: Provide leader line for concrete wash -out.
vi. Provide /show paved construction entrance (PCE). (Rev. 1) Addressed.
vii. New: Relocate 21-pg. VAR10 from Sec. 2 to Sec. 11. Once 1-2 pg. DEQ VAR10
coverage letter is received, this document is included with SWPPP at Sec. 2. (Rev. 2)
Albemarle will relocate 21-pg. VAR10 from initial SWPPPs to Sec. 11, rev. SWPPPs.
Albemarle needs 2 complete print copies of SWPPP with rev. ESC /SWM Plan sheets.
Final print copies to include I I" x 17" SWM /ESC Plan sheet inserts (Sec. 4, 5).
viii. New: Indicate on -site location of rain gauge. (Rev. 2) Addressed.
ix. New: Recommend include inspection frequency listed at VAR10 Part 1.B.4.d.(1/2), since
this inspection frequency applies [text image, below]. (Rev. 2) Not addressed.
Recommendation withdrawn.
d. The applicable SWPPP inspection requirements specified in Part II F 2 shall be amended as
follows:
(1) 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
(2) Representative inspections used by utility line installation, pipeline construction, or other
similar linear construction activities shall inspect all outfalls discharging to surface waters
identified as impaired or for which a TMDL wasteload allocation has been established and
approved prior to the term of this general permit.
The PPP content requirements can be found in County Code section 17-404.
1. See A /Sec. 6 comments, above. (Rev. 3) Addressed.
C. Stormwater Management Plan (SWMP) — (Rev. 3) Prior review comments addressed.
VSMP Regulation 9VAC25-870-108 requires the VSMP authority to approve or disapprove a SWMP.
This plan is approved pending completion of non -design -related items required for Final Plan Approval
(Easements recorded /Print submittal. DEQ VAR10 permit issuance + bonds required for Grading permit).
1. Please ref. 17-303. Proposed Vineyard Processing building is not exempt from VSMP
requirements; ,
(Image removed with Rev. 2 comments.)

quantity requirements listed at 9VAC25-870-66. Note: pre- /post -development drainage maps are

required. Pre -post development hydrologic calculations are required. Technical criteria IIB
applies. (Rev. 1) Partially addressed. As follow-up:
a. If plan intends to show compliance with discharge to a manmade system, it is unclear that
a manmade system exists along Dick Woods Road (SR 637). Provide plan detail.
Include topography, labels, narrative, etc. that explain compliance with 9VAC25-870-
66.13. La. Please note, velocity analysis required. If proposed Ex. detention outfall
discharges to a poorly -defined or non-existent roadside ditch, then design must consider
9VAC25-870-66.B.3 (Energy balance /Natural stormwater conveyance systems). (Rev.
2) Addressed. Energy balance used. Calculation checked using S = (1000/CN) -10 =
6.39344, and Q1-YR/PosT = 0.1903 cfs.
b. Engineering anticipates discharge to a roadside ditch (manmade conveyance), and
requests Ex. ditch details, section, and velocity analysis, per 9VAC25-870-66.B.1. (Rev.
2) NA, discharge to natural stormwater conveyance; energy balance required.
c. Limits of Anal: Evaluate channel protection to point site DA < 1 % total watershed
Area of a receiving stream; ref. 9VAC25-870-66.B.4. (Rev. 2) NA, energy balance.
d. (9VAC25-870-66.C. L/2.): Design meets flood protection requirement at 9VAC25-870-
66.C.2.b. Please include this statement on plan sheet C-1.02. (Rev. 2) Addressed.
e. It is not immediately apparent why a level spreader (LS) is required. SWM facilities
cannot be located within VDOT RW. This facility is not, but appears to lie near a
roadside ditch (2.a., above) which will cancel tendency for sheet flow to disperse.
(Ditches concentrate flow.) 9VAC25-870-66.D. is not applicable. Recommend remove
LS from plans, which may limit design, construction, and SWM Facility easement platting
expense. Last: if located too close to a ditch, VDOT equipment may damage this facility
during routine ditch maintenance operations. (Rev. 2) Withdrawn, no LS.
f Extended detention (DEQ Stormwater Design Specification No. 15):
i. Consider design parameters, specifications, and requirements at

Process
After approval, plans will need to be bonded. The bonding process is begun by submitting a bond estimate request
form and fee to the Department of Community Development. One of the plan reviewers will 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 (SWPPP Registration Statement).
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.
Easements must be recorded prior to VSMP approval. Proof of purchase of nutrient credits (if any) is required to
receive a Grading Permit.
After DEQ coverage is issued, the County can hold a pre -construction conference. Applicants will need to complete
the request using 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 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;
