This project is approved. The rationale is given in the comments below. 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. The SWPPP was not found with this submittal. (Rev. 1)Comment partially addressed. The Certification will need to be signed. (Rev. 2) Comment addressed. B. Pollution Prevention Plan(PPP) The PPP content requirements can be found in County Code section 17-404. 1. The PPP exhibit will need to be included in the SWPPP. (Rev. 1)Comment addressed. C. Stormwater Management Plan (SWMP) VSMP Regulation 9VAC25-870-108 requires the VSMP authority to approve or disapprove a SWMP. This plan is approved, 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. The 1.01 lbs/yr of nutrient credits will need to be purchased before the plans are approved. Please contact Ana Kilmer before purchasing the credits. (Rev. 1)Comment not addressed. (Rev. 2) Comment addressed. 2. Provide the soils reports/infiltration analysis for the soils in the area of the infiltration tank. The design infiltration rate may be no greater than 50%of the measured rate(BMP Spec. 8). Also include the distance from the bottom of the practice to the seasonal high water table and/or bedrock(2' minimum). (Rev. 1)Comment addressed. Engineering Review Comments Page 2 of 2 3.

Add more detail to the construction sequence regarding the infiltration tank, including how the underlying soils will avoid compaction. (Rev. 1) Comment addressed. The VSMP permit application and all plans may be resubmitted for approval when all comments have been satisfactorily addressed. For re-submittals please provide 2 copies of the complete permit package with a completed application form. Engineering plan review staff are available from 2-4 PM on Thursdays, should you require a meeting to discuss this review. 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. After DEQ coverage is issued, via the coverage letter,the County can hold a pre-construction conference. Applicants will need to complete the request for a pre-construction conference form,and pay the remainder of the application fee. The form identifies the contractor and responsible land disturber,and the fee remaining to be paid. This will be checked by county staff, and upon approval, a pre-construction conference will be scheduled with the County inspector. At the pre-construction conference, should everything proceed satisfactorily, a joint VSMP and grading permit will be issued by the County so that work may begin.

The specific changes are outlined below. A. Stormwater Pollution Prevention Plan (SWPPP) 1. The SWPPP was not found with this submittal. The SWPPP is included in the current submittal. B. Pollution Prevention Plan (PPP) 1. The PPP Exhibit will need to be included in the SWPPP. The PPP is included with the SWPPP. C. Stormwater Management Plan (SWMP) 1. The 1.01 lbs/yr of nutrient credits will need to be purchased before the plans are approved. Please contact Ana Kilmer before purchasing the credits. Tom Ross has drafted a contract for purchasing the nutrient credits,which has been sent to Ana Kilmer for review. 2. Provide the soils reports/infiltrations analysis for the soils in the area of the infiltration tank. The design infiltration rate may be no greater than 50% of the measured rate(BMP Spec. 8). Also include the distance from the bottom of the practice to the seasonal high water table and/or bedrock(2' minimum). The soils report is included with the current submittal. The design infiltration rate for the maximum depth of the infiltration practice is 50%of the measured rate,as indicated in the computation that is included in this submittal.As indicated in the soils report,the tests were terminated at 25' of depth, 3-7 feet below the proposed bottom of the practice, and did not encounter groundwater or bedrock. 3. Provide a maintenance and inspection schedule for the underground practices. A maintenance and inspection schedule is now included. D. Erosion and Sediment Control Plan (ESCP) 1. The diversions on Phase 2 do not appear to function as shown (breaking grade, directed into a building, located on top of a retaining wall. The diversions shown had been copied from Phase 1 without sufficient attention, and had many problems.The diversions should now be shown in Phase 2 without those problems. 2. Add more detail to the construction sequence regarding the infiltration tank, including how the underlying soils will avoid compaction. The underlying soils are protected from compaction by the depth to the bottom of the practice. The bottom of the practice is 20-27' below existing grade,and a minimum of 11.5' below finished grade.As specified in the plan, contractors will not cut down to install the infiltration until the site is fully graded and stabilized.
