After reviewing your application, we have decided that these impacts are covered by General Water Quality Certification Number 3886.

In addition, you should acquire any other federal, state or local permits before you proceed with your project including (but not limited to) Sediment and Erosion Control, Non - Discharge and Water Supply Watershed regulations. This approval will expire with the accompanying 404 permit. This approval is valid solely for the purpose and design described in your application (unless modified below). Should your project change, you must notify the NCDWQ and submit a new application. If the property is sold, the new owner must be given a copy of this Certification and approval letter, and is thereby responsible for complying with all the conditions. If total wetland fills for this project (now or in the future) exceed one acre, or of total impacts to streams (now or in the future) exceed 150 linear feet, compensatory mitigation may be required as described in 15A NCAC 2H.0506 (h) (6) and (7). For this approval to remain valid, you must adhere to the conditions listed in the attached certification(s) and any additional conditions listed below. Condition(s) of Certification: 1.

Stormwater management from all impervious surfaces other than the NCDOT maintained portion of Summit Meadow Lane shall be the responsibility of Appalachian Regional Health System. The Division approves the SMP for all non - roadway built upon areas consisting of one Wet Detention Basin and one Bioretention Cell and all associated stormwater conveyances, inlet and outlet structures, and the grading and drainage patterns depicted on plan sheets dated March 7, 2014 and March 17, 2014, which are incorporated by reference and are enforceable by the Division. The following conditions also apply: a) The maximum allowable drainage area for the approved Chestnut Ridge Medical Facility shall be 229,997 square feet and the maximum allowable built -upon area within that drainage area shall be 124,582 square feet draining to the Wet Detention Basin and 100,624 square feet and the maximum allowable built -upon area within that drainage area shall be 54,450 square feet draining to the Bioretention Cell. Any changes to these maximum areas shall require the applicant to submit and receive approval for a revised stormwater management plan by the Division. b) The footprint of all stormwater management devices as well as an additional 10 -foot wide area on all sides of the devices shall be located in either: public rights -of -way; dedicated common areas; or recorded easement areas. The final plats for the project showing all such rights -of -way, common areas and easement areas shall be in accordance with the approved plans. c) The approved SMP shall be constructed and operational before any permanent building or other structure is occupied at the site. d) The SMP for the Chestnut Ridge Medical Facility may not be modified without prior written authorization from the Division. e) Maintenance activities for the Wet Detention Basin and the Bioretention Cell shall be performed in accordance with the notarized O &M agreements signed by Richard Sparks on March 12, 2014.

During the construction of the project, no staging of equipment of any kind is permitted in waters of the U.S., or protected riparian buffers. - 5. The dimension, pattern and profile of the stream above and below the crossing shall not be modified. Disturbed floodplains and streams shall be restored to natural geomorphic conditions. 6. The use of rip -rap above the Normal High Water Mark shall be minimized. Any rip -rap placed for stream stabilization shall be placed in stream channels in such a manner that it does not impede aquatic life passage. 7. The Permittee shall ensure that the final design drawings adhere to the permit and to the permit drawings submitted for approval. 8. Heavy equipment shall be operated from the banks rather than in the stream channel in order to minimize sedimentation and reduce the introduction of other pollutants into the stream. 9. All mechanized equipment operated near surface waters must be regularly inspected and maintained to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials. 10. No rock, sand or other materials shall be dredged from the stream channel except where authorized by this certification. 11. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is prohibited. 12.

The outside buffer, wetland or water boundary located within the construction corridor approved by this authorization shall be clearly marked by highly visible fencing prior to any land disturbing activities. Impacts to areas within the fencing are prohibited unless otherwise authorized by this certification. 14.

Native riparian vegetation (ex. list herbaceous, trees, and shrubs native to your geographic region) must be reestablished in the riparian areas within the construction limits of the project by the end of the growing season following completion of construction. 18. There shall be no excavation from, or waste disposal into, jurisdictional wetlands or waters associated with this permit without appropriate modification. Should waste or borrow sites, or access roads to waste or borrow sites, be located in wetlands or streams, compensatory mitigation will be required since that is a direct impact from road construction activities.
