SUPPLEMENTAL DIRECT TESTIMONY

OF

RYAN GILCHRIST

ON BEHALF OF MASON DIXON SOLAR CENTER, LLC

November 10, 2016

5104053.1 49674/132367 11/09/2016

Q. PLEASE STATE YOUR NAME, BUSINESS ADDRESS AND TITLE. 1

A. My name is Ryan Gilchrist, Project Developer, Coronal Development Services, LLC, 321 2

East Main Street, Charlottesville, Virginia 22902. 3

Q. ARE YOU THE SAME RYAN GILCHRIST THAT SUBMITTED DIRECT 4

TESTIMONY TO THE COMMISSION ON OCTOBER 20, 2016 IN THIS 5

PROCEEDING? 6

A. Yes, I am. 7

Q. WHAT IS THE PURPOSE OF YOUR SUPPLEMENTAL DIRECT TESTIMONY? 8

A. The purpose of my supplemental direct testimony is to provide additional information for 9

the record in this proceeding that further clarifies that the Mason Dixon Solar Project (the 10

“Project”) does not present a glare hazard to the Hagerstown Regional Airport. 11

Q. WHERE IS THE PROJECT LOCATED RELATIVE TO THE HAGERSTOWN 12

REGIONAL AIRPORT? 13

A. The Hagerstown Regional Airport is located approximately 3,200 feet southeast of the 14

Project Site. 15

Q. DOES THE ERD SUBMITTED WITH MASON DIXON’S APPLICATION FOR A 16

CPCN IN THIS PROCEEDING INCLUDE INFORMATION ON GLARE? 17

A. Yes, it does. 6 of the ERD states that Mason Dixon has corresponded with the 18

Federal Aviation Administration (“FAA”) via submission of a FAA Form 7460-1. The 19

glare analysis provided to the FAA is included as Attachment A to my supplemental 20

5104053.1 49674/132367 11/09/2016

direct testimony.1 After performing analysis related to the Project’s proposed height, 1

location, and glare, the FAA issued “Determination of No Hazard to Air Navigation” 2

letters to Mason Dixon corresponding to the boundary points of the Project. These letters 3

are included as Appendix E to the ERD. 4

Q. DID MASON DIXON PERFORM ANY ADDITIONAL OUTREACH TO 5

FURTHER CONFIRM THE PROJECT WILL HAVE NO GLARE IMPACT ON 6

THE HAGERSTOWN REGIONAL AIRPORT? 7

Yes, it did. Mason Dixon sought a determination from the Maryland Department of 8

Transportation Aviation Administration (“MAA”) that the Project will not present a glare 9

hazard to the Hagerstown Regional Airport. After its review, MAA determined the 10

Project presents “no solar glare hazards for any of [the] runway approaches at 11

Hagerstown Regional Airport” and thus would not be “an obstruction or hazard to air 12

navigation.” The correspondence from MAA confirming this conclusion in included as 13

Attachment B to my supplemental direct testimony. 14

Additionally, Mason Dixon provided glare studies to and sought input from the 15

Hagerstown Regional Airport, which also received a copy of MAA’s determination. As 16

indicated in the email correspondence included as Attachment C to my supplemental 17

direct testimony, based on this information the Hagerstown Regional Airport does not 18

object to the Project for any reason, including on the basis of glare impacts. 19

Q. DO THESE CORRESPONDENCES INDICATE THAT THE PROJECT DOES 20

NOT PRESENT A GLARE HAZARD TO THE HAGERSTOWN REGIONAL 21

AIRPORT? 22

1 All glare analysis for the project utilized the Project’s proposed single-axis tracking configuration.

5104053.1 49674/132367 11/09/2016

Yes. These correspondences indicate that the Project does not present a glare hazard to 1

the Hagerstown Regional Airport. 2

Q. DOES THIS CONCLUDE YOUR SUPPLEMENTAL DIRECT TESTIMONY? 3

A. Yes, it does. 4

Good morning Ben,

Hagerstown Regional Airport has no objection to the Mason Dixon, LLC solar fam installation. Federal Aviation Administration as well as Maryland Aviation Administration find no objections so accordingly, we have none as well.

Best of luck with your project and we appreciate your correspondence!

Regards,

Phil

Mr. Ridenour,

Thank you for returning my call this afternoon. As discussed, please find attached the glare analyses for the Mason Dixon Solar Center, which is located about 0.5 miles West of the Hagerstown Regional Airport. We performed the analyses for each flight approach path corresponding to the two active runways at the facility.

Included as well are the following supplements:

• Mason Dixon Solar Center Project Summary• USGS map depicting location in relation to Hagerstown Regional Airport• 4 x FAA Approvals stating ³No Hazard to Air Navigation² for each of the project boundary points

If you have any additional questions, please feel free to reach out to me directly.
