The VSMP application content requirements can be found in County Code section 17-401. 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. Provide a SWPPP including Pollution Prevention Plan [17-401, 17-405] (Rev. 2) Addressed B. Pollution Prevention Plan (PPP) The PPP content requirements can be found in County Code section 17-404. 1. No Pollution Prevention Plan was provided in the submittal. Please provide a PPP as described in County Code [17-404]. (Rev. 2) Addressed 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. Plans show LOD extending onto both properties to the south oC the proposed project. Please provide TMP and owner info to application with required signatures. (Rev. 2) Addressed 2. Provide calculations using the VRRM New Development Compliance Spreadsheet instead of the Engineering Review Comments Page 2 of 2 plan content requirements can be found in County Code section 17-402. 1. Provide a sequence of construction to show how installation of culvert B will prevent conflict with the use of sediment trap #1. Provide phasing for E&S to show how these conflicts will be addressed after the sediment trap #I is removed during construction of guard house and installation of Culvert B. Rev. 2 — Addressed 2. Provide updated drainage areas to show that moving culvert A does not increase drainage area to sediment trap #2 to greater than 3 acres. If the drainage area is increased to greater than 3 acres, a sediment trap is no longer sufficient, and a sediment basin will need to be included. Rev. 2 — Addressed 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. 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.

A PLAT of these areas must be provided along with a Deed of Easement. Limit plan and VRRM analysis to the LOD and area within the buffer, including mitigation areas, which are to be conserved as forested/open space. Incorporating entire parcel as forested/conserved open space will provide difficulty during future development. (Rev. 2) The County has determined that these areas are to be managed under a stormwater Management Agreement. This agreement will need to be signed along with a PLAT and deed. PENDING... 4.
