Reviewer:
John Anderson, PE
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 Amendment to approved WPO Plan is
disapproved.
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.
1. SWPPP:
a. Please revise /update approved SWPPP with:
i. Amended plan sheets (I I" x17").
ii. Registration Statement (Sec. 1 /SWPPP template) that indicates increase in limits of
disturbance from 0.57 Ac. to 0.66 Ac., revises estimated begin -end construction dates,
and is signed /dated by responsible corporate official, if not already. Please call if any
questions.
iii. Update PPP Exhibit, SWPPP Sec. 6.A.
iv. Provide update as needed to named individuals listed at:
1. SWPPP, Sec. 6.E. -Named individual responsible for pollution prevention
practices.
2. Sec. 8 — Named individual responsible for VESCH compliance inspections.
B. Pollution Prevention Plan (PPP) —see SWPPP item l.a.iii., above.
The PPP content requirements can be found in County Code section 17-404.
C. Stormwater Management Plan (SWMP)
VSMP Regulation 9VAC25-870-108 requires the VSMP authority to approve or disapprove a SWMP. This
plan is disapproved for reasons listed below. The stormwater management plan content requirements can be
found in County Code section 17-403.

1. Concentrated storm discharge near entrance to DS Tavern must meet energy balance. Statement at
Stormwater Quantity Note, cover sheet/C6.0, that `this site is outside the limits of analysis for Flood and
Channel Protection requirements due to the site contributing drainage area being less than 1% of the total
contributing drainage area at the point of analysis' does not recognize DEQ position that concentrated
discharge even at limit of analysis must, at point of discharge, meet the energy balance requirement. Please
revise design to meet EB at point of analysis. Feel free to call to discuss. (Amendment #1 Review Rev.):
Withdrawn. Applicant reached out to discuss (5/9 email, 5111 tel.): Issue does not invoke DEQ guidance
relative to energy balance since DS Tavern will discharge (with completion of DS Tavern improvements)
to an existne storm pipe network labeled existing (contemporaneous with Amendment #1 review). Halifax
House is constructing a storm pipe network, meaning DS Tavernwill discharge to a manmade system
subject to 9VAC25-870-66B.1. Revised plan will clarify via identical storrnwater management narrative
notes on C6.0 /cover sheet that an existing manmade storm network (Halifax H.) will receive DS Tavern
runoff, and may highlight applicable requirements at 9VAC25-870-66.B.1. Note: plan identified off -site
manmade storm network system elements as existing. Review Error.

if Applicant provides express permission for Albemarle to apply existing now -posted $17,390
bond amount to any aspect of the WPO plan (ESC; S`v 4, Mitigation). Applicant reached out to
ensure that bond posted 4 May 2022 was sufficient to meet project need (Natalie LaRoe email,
April 13, 2022 2:43 PM) and was assured by this reviewer that the bond amount was accurate.
This email arrived several days after the WPO plan amendment (now under review) was submitted
11-Apr, affording Albemarle opportunity to check submittal and note whether additional bond
amount would be required. It is a disservice to assure an applicant seeking to confirm a bond
estimate accurate, that it is, when information is available that additional bond may be required.
Experience dictates additional bond may be required, but in this circumstance, once ESC measures
on the Amended WPO plan are installed, it is reasonable to estimate (with Applicant permission)

(Amendment #1 Review Rev.): Revised. See item 1, above. There is no SWM component of
design, only ESC/Mitigation. As matter of fairness, Albemarle requests written assurance from
DS Tavern that posted $17,390 WPO plan bond amount may be exercised, if necessary, to ensure
Mitigation Plan plantings are installed per plan, not simply applied to ESC plan measures only.

a. Revise p. 4-6, consistent with final revised SWM design, consistent with 9VAC25-870-66.
(Amendment #1 Review Rev.): Revised. See item 1., above.
b. Revise title to include ref. to WPO202100064 Amendment 1.
D. Erosion and Sediment Control Plan (ESCP)
Virginia Code §62.1-44.15:55 requires the VESCP authority to approve or disapprove an ESCP. The
Amended ESC plan is approved.
Process:
Applicant has or will soon receive a Grading Permit for the initially -approved plan by Lineage, d. 12/16/21 which
authorizes 0.57 Ac. land disturbance, but does not show SAIM faoilities(detention , .' -- e*ao),, OF Mitigation Plan;

plantings (canopy trees, shrubs, meadow mix). April 11, 2022, the Amendment plan was submitted and available
for cursory review to check for any effect on WPO plan bond amount. Reviewer failed to check this plan, and in
fairness to applicant, an approach to use of bond posted 4 May 2022 is outlined above. Albemarle requests letter of
permission from Owner, DS Tavern, to apply now -posted $17,390 WPO plan bond amount to any aspect of the
WPO plan, once ESC measures are installed. With Applicant /Owner's permission, the current bond amount should
prove sufficient, if available to apply this amount to Mitigation Plantings, linitted detention pipe-, or ESC measures.

Applicant purchased 0.29 lb. phosphorus nutrient credits to cover initially -approved and amended WPO Plan.
Credits approved 4/15/22.
It is reviewer's understanding that Albemarle and Applicant have met or will soon meet in pre -construction
conference. This project is eligible to proceed under initiallkapproved plan (0.57 Ac. LOD), but is not authorized
to disturb 0.66 Ac. shown with Amendment design (Woolley Engineering).
Thank you.
