Dear Mr. Deel:
On behalf of Wilson Jones Company, Atlanta Environmental Management, Inc. (AEM) is
providing this response to your comments regarding the Storm Water Pollution Prevention Plan
dated May 11, 2015.
Comment 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 ESCP, (3) a SWMP, and(4) any TMDL measures necessary.
1. Provided SWPPP appears to adequately address all items in County Code section
17-405. Please reflect below requested changes in resubmitted SWPPP.
Response: No edits, additions, or deletions required.
Comment B: Pollution Prevention Plan (PPP)—The PPP content requirements can be found in
County Code section 17-404.
1. Provided PPP appears to adequately address all items in County Code section 17-
404.
Response: No edits, additions, or deletions required.
Comment 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.
1. Please explain what is to be done with the excavated material.
Response: Figure 6 was revised to indicate that "Excavated materials will be properly
manifested and transported off-site for landfill disposal. Soils and debris will be disposed
of in permitted facilities."
2. Are the "refurbished and/or installed access roads"to be permanent or temporary? If
they are intended to remain in place, a nutrient (phosphorus) load reduction is

�+- required, as there will be an increase in impervious cover. Please remove the access
roads once excavations are complete or provide SWM to account for the increase in
imperviousness. Additionally, the existing roads or paths on this parcel do not appear
to have cover, therefore refurbishment (adding crushed stone) will result in an
increase in impervious cover requiring load reduction. Load reduction calculations
[must] be performed using the Virginia Runoff Reduction Method (VRRM)
spreadsheet, which can be found at
http://www.deq.virginia.gov/Programs/Water/Laws,Regulations,Guidance/Guidance/
Storm waterManagementGuidance.aspx
Response: The refurbished gravel roads are permanent. Under the direction of
Mr. Justin Deel, County of Albemarle, Department of Community Development, the
Virginia Runoff Reduction Method (VRRM) spreadsheet model was run and the results
were evaluated in accordance with the appropriate evaluation criteria. Figure 6 was
revised to include the identification of "grass channels" and "conserved open space."
The VRRM spreadsheet results have been included in Section 5—Storm Water
Management Plan.
Comment 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 disapproved,
and the reasons are provided in the comments below. The erosion control plan content
requirements can be found in County Code section 17-402.
1. Please show "construction entrance" (CE) [Virginia Erosion & Sediment Control
Handbook, 3.02]on E&SC plan.
Response: Figure 4 was revised to indicate the location of the construction entrance
and the location of the stockpile areas.
2. Please show staging and stockpile areas on plan.
Response: Figure 4 was revised by the addition of Note 7 to indicate that "Any soil
staged or stockpiled will be covered by polyethylene sheeting."
If you need anything else or have any questions, please call us at 404-329-9006.
