RE: Response to Comments
Castle Rock Farm — Phase 1
Balzer Project No: 34210060.00

This letter serves as our written responses to the County comments on the subject project:
A. Stormwater Pollution Prevention Plan (SWPPP)
1. Provide a SWPPP, including a completed and signed DEQ Registration Form
(though no DEQ permit will be required) and a signed Certification.
• A SWPPP, including a completed and signed DEQ Registration Form and a signed
Certification has been provided
B. Pollution Prevention Plan (PPP)
2. Provide a PPP with the SWPPP.
• A PPP has been provided with the SWPPP.
C. Stormwater Management Plan (SWMP)
3. Projects disturbing 10,000sf or more and meeting the conditions of 17-302 are
subject to the VSMP regulations (17-401-405) and will need to meet both quantity
and quality requirements. The sheet flow for quantity appears acceptable.
• Noted.
4. The quality compliance as determined in the DEQ VRRM worksheet will need to
be met. If nutrient credits will be purchased, be aware that the site drains to
impaired waters as determined by DEQ and the credits will need to be purchased
from within the same 8-digit HUC (the Ivy Creek bank and the Rivanna River bank
are both acceptable). Please contact Ana Kilmer in our office prior to purchasing
credits.
• To achieve water quality standards, a total of 1.18 lbs. of Phosphorus is required to
be treated. A total of 1.18 lbs. was achieved through the use of open space. This is
now shown on Sheet C4.0.
