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 Engineering Review Comments Page 2 of 2 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.

This project is denied. The rationale is given in the comments below. The application may be resubmitted for approval if all of the items below are satisfactorily addressed. 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 ESOP, (3) a SWMP, and (4) any TMDL measures necessary. Please have the owner fill out the required forms for the SWPPP for plan approval. The owner is the Operator until the plan is approved, the "Operator" can be transferred to additional personnel at anytime during the duration of the project, see transfer forms in SWPPP.

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. VRRM updated spread sheet appears to be for 11.76 acres of disturbance. The VRRM spreadsheet should be for the proposed new construction/ disturbed area. The drainage area to the water quality structure appears to be just under 2 acres. Please Correct the VRRM Spreadsheet and show the drainage areas on the plan for conformation.

State instructions were "Do not change Annual Rainfall (inches) of 43" this VRRM has been altered to show 46 inches annual rainfall. b. Soils Hydrological groups do not appear correct. F. VSMP: SWPPP: Erosion and Sediment Control Plan 1. Perimeter sediment trapping measures and diversion dikes must be out of the work area, and in places where they can be installed before grading activities commence. The plan does not appear to show Engineering Review Comments Page 2 of 2 adequate protection for the site work. SWM basin could be utilized for E &SC protection. 2. The narrative does not appear to be for this project or the cut and paste was not edited properly prior to submittal. Please correct. 3.

The effective date of your coverage under this general permit is July 1, 2014 or the date of this letter,whichever is later. A copy of the general permit can be obtained from DEQ's webpage at the following location: http://www.dea.virginia.gov/Portals/0/DEQ/Water/Publications/CGP2014.pdf. The general permit contains the applicable Stormwater Pollution Prevention Plan (SWPPP) requirements and other conditions of coverage. Please print the general permit and read it carefully as you will be responsible for compliance with all permit conditions. DEQ staff has determined that the proposed land-disturbing activity will discharge to a surface water identified as impaired or for which a TMDL wasteload allocation has been established and approved prior to the term of the general permit for(i) sediment or a sediment-related parameter or (ii) nutrients. Therefore, the following general permit(Part I.B.4)and SWPPP requirements(Part II.A.5)must be implemented for the land-disturbing activity: • Permanent or temporary soil stabilization shall be applied to denuded areas within seven (7) days after final grade is reached on any portion of the site; • Nutrients (e.g., fertilizers) shall be applied in accordance with manufacturer's recommendations or an approved nutrient management plan and shall not be applied during rainfall events; • Inspections shall be conducted at a frequency of (i) at least once every four (4) business days or (ii) at least once every(5) business days and no later than 48 hours following a measurable storm event. In the event that a measurable storm event occurs when there are more than 48 hours between business days, the inspection shall be conducted on the next business day; and • Representative inspections used by utility line installation, pipeline construction, or other similar linear construction activities shall inspect all outfalls. The general permit will expire on June 30, 2019. The conditions of the general permit require that you submit a new registration statement at least 90 days prior to that date if you wish to continue coverage under the general permit, unless permission for a later date has been granted by the Board. Permission cannot be granted to submit the registration statement after the expiration date of the general permit. If you have any questions about this permit, please contact the DEQ Office of Stormwater Management at ConstructionGP edea.virginia.gov. Sincerely, • Frederick K. Cunningham, Director Office of Water Permits 2
