RE: Keswick WWTP Improvements —Minor Amendment Site Plan Review — SDP2021-00025 -
Comment Response Letter
Dear Mr. Anderson:
We have reviewed all of your comments from Revision dated May 5, 2021 and made the
necessary revisions. Please find our responses to the comments below in bold lettering.
Note: Major revision to review comments. Items 1.-6., below, withdrawn. Ref. Bruce Strickland
email, Timmons Group (May 5, 2021 12:56PM): 'This project will not expand the permitted
capacity of the central sewer system. This is an enhancement to the existing treatment process
for greater reliability and resiliency, so we believe that the requirements of Ch. 16 are not
applicable in this case.'
1. If this Application has completed clerk of board of Superviors notification outlined in Ch.
16, please notify Engineering. Also, please include relevant dates of board action
relative to this application on plan sheet C0.0, if Albemarle County board of supervisors
has considered this WWTP improvement proposal prior to this date. (05/05/2021)
Withdrawn; ref. Applicant email, May 5, 2021 12:56PM.
Acknowledged
2. Per 16-102, notify the board of supervisors at least (60) days prior to commencing
construction of Keswick Wastewater Treatment Plant Improvements. The notice shall
include the following: (05/05/2021) Withdrawn; ref. Applicant email, May 5, 2021

Acknowledged
a. The location of the proposed central sewerage system. It may be helpful to
reference antecedent Keswick WWTP applications, or approved plans, since this
plan proposes:
i. (Expansion) improvement of an existing central sewerage system,
including:
ENGINEERING I DESIGN I TECHNOLOGY
1. New blower, pipes, restraints, thrust blocks, new 6" influent
pump station ductile iron force main, valve vault, gate valve/s,
equalization basin, electrical building, generator, and additional
miscellaneous items.
2. In order to provide additional capacity for new or expanded
Keswick community facilities, or additional connections (Keswick
Hall Spa, for example, though precise capacity or facilities served
is not readily apparent with this Application).
b. The number of connections proposed to be served by the central sewerage
system:
i. If no new connections beyond currently -served Keswick facilities or
buildings will be served with this WWTP improvement project, please
state this.
ii. If new Keswick community connections are provided or new buildings
served, please list/identify buildings, facilities, etc.
iii. If expansion improvement increases WWTP capacity by a measurable
amount, please report increased WWTP treatment capacity; if
equalization basin, electrical building, and appurtenant structures only
enhance wastewater treatment, please state this.
c. A statement describing the type of proposed central sewerage system
(expansion) and explaining the reasons the system or supply is needed.
i. Engineering requests brief narrative that addresses items listed at code
Sec. 16-102.1-3.
d. Please furnish three (3) copies of the preliminary plans for the central sewerage
system to the clerk of Albemarle County board of supervisors with cover letter
addressing notification items listed at 16-102 for SDP202100025, Keswick
Wastewater Treatment Plant Improvements, d. 03/22/21, Minor Site Plan
Amendment SDP199100097.

3. Engineering Division has received copy of Application as SDP202100025 and is not
dependent on transmittal of copy of plans already received to initiate review or consider
technical aspects of the proposed WWTP. (Sec. 16-603) (05/05/2021) Withdrawn; ref.
Applicant email, May 5, 2021 12:56 PM.
Acknowledged
4. Sec. 16-104 requires proposed improvements to Keswick WWTP be placed on the
agenda of the board of supervisors for consideration at a regular board meeting. The
hearing shall not be conducted until the county engineer has completed a review of the
plans submitted by the applicant. Prior to the meeting at which the proposal will be
considered, the county engineer shall submit a written recommendation to the board.
The applicant shall appear in person (or remotely) when the proposal is considered by
the board. (05/05/2021) Withdrawn; ref. Applicant email, May 5, 2021 12:56 PM.
Acknowledged
5. Sec. 16-105 states (05/05/2021) Withdrawn; ref. Applicant email, May 5, 2021 12:5613M.
a. After consideration of a proposal as provided in section 16-104, the board of
supervisors may approve or disapprove the proposal. If the board approves the
proposal, it shall specify the number of connections that may be made to the
central sewerage system.
b. The board may condition its approval of a central sewerage system upon the
approval of the applicant's final plans by the county engineer, the health
department, and the Virginia Department of Environmental Quality, and wither
approval by or proof of notification to, any other applicable state or federal
department or agency.

6. The county engineer anticipates no objection to Matthew R. Miller, PE, WWTP
improvements design on a technical basis provided Agencies listed at review item 5.b.
have no objection, and applicant finishes evidence of VDH written acceptance of design
without objection as sufficient to meet relevant sewage collection and treatment (SCAT)
regulations. Engineering will likely, on agency acceptance basis, recommend to the
board of supervisors' approval of design intended to meet current or expanded
wastewater treatment needs at the Keswick Community. (05/05/2021 Withdrawn; ref.
Applicant email, May 5, 2021 12:56PM.
Acknowledged
7. Provide evidence of coordination with DEQ/VDH. Provide evidence of design acceptance
by VDH.
VDH does not have jurisdiction over this type of wastewater project. This wastewater project
is governed by the Sewage Collection and Treatment Regulations, 9VAC25-790, over which
DEQ has jurisdiction. Please refer to the attached email correspondence regarding the
preliminary engineering conference held with DEQ on 2/19/21.
8. Estimate area of land disturbance associated with SDP202100025. Meet water
protection Ordinance requirements typically triggered if area of land disturbance is >
10,000 square feet. If WPO Application is required, the Minor Site Plan Amendment
cannot be approved prior to WPO Plan approval.
Land Disturbance for this project is under 10,000 SF and therefore a WPO Application and plan
is not required.
We have included PDF copies of the plans and calculations for your review. If you have any
questions or comments, please feel free to give me a call at 434.295.5624 or email at
