Mason Dixon Solar Center, LLC Certificate of Public Convenience and Necessity Environmental Review Document Addendum

|P a g e| 1

SECTION I – ADDENDUM OVERVIEW The purpose of this addendum to Mason Dixon Solar Center, LLC’s (the Applicant) Environmental Review Document (ERD) is to modify the Mason Dixon Solar Center’s (the Project) scope of construction to include an underground 34.5kV generation tie line and breaker located on an adjacent property. All other Project characteristics submitted by the Applicant in the original ERD, dated September 14, 2016, remain valid and uncharged with the exception of this one modification. This work was previously to be completed by FirstEnergy (FE) in existing FE right-of-ways; however, additional interconnection study work determined that it was more feasible for this work to be completed under the Project’s scope.

The Project, as proposed by the Applicant, will now be comprised of two components located on two privately-owned properties; a solar PV array portion of the Project (Array) that will be located on land (Tax Map 10, Parcel 68) owned by 2003 Mason Dixon, LLC (Mason Dixon Property) and an underground generation tie line and breaker portion of the Project (Interconnection) that will be located on land (Tax Map 10, Parcel 142) owned by Lowell & Luella Eby (Eby Property). The Applicant has long-term lease and easement options with the Landowners for the use of the Properties for the Project.

The construction of the Interconnection portion of the Project will have little effect on the landscape and current use of the Eby property. Construction of the underground 34.5kV generation tie line on the Eby Property will require only a temporary disturbance with no impervious surfaces. Upon completion and stabilization, the Ebys will be able to continue to utilize the affected area for agricultural purposes. The breaker facilities will occupy a minimal land area (approximately 75 feet by 75 feet), and will likely require an asphalt entrance apron, a gravel pad, and a ten-foot high perimeter fence around the electrical equipment and wooden utility poles. Screening in the form of a landscape buffer will be installed around the perimeter of the breaker facilities.

As mentioned in Section VI.A.3 of the original ERD, the Applicant initially examined the Eby Property as part of the Project, but the Eby Property was removed prior to application. Accordingly some of the environmental due diligence documents included in the original ERD were comprehensive of the Eby property, but it was stated that references to the Eby Property should be ignored. However, the Eby Property is now being re-introduced as part of the Project and is necessary for interconnection. This addendum includes additional supporting documentation for the Interconnection portion of the Project that was not included with the original ERD.

The updated Interconnection portion of the Project is represented as part of the Site in the attached figures. The Interconnection portion of the Project is expected to affect less than 5 acres of land once implemented; however, the study area was comprised of approximately 30 acres. The Project in total, including the Array and Interconnection portions, will affect approximately 145 – 155 acres of land (Site).

The overall Site is located south of Pennsylvania Route 163 (Mason Dixon Road) and east of Maryland Route 63 (Greencastle Pike) in Washington County, Maryland (see Figures 1 & 2). Franklin County, Pennsylvania adjoins a portion of the Site to the north. The Properties are addressed as 17939 Mason Dixon Road (Mason Dixon Property) and 14611 Greencastle Pike (Eby Property) in Hagerstown, Maryland 21740. The approximate center of the Site is located at approximately 39°42'57.13"N Latitude and 77°45'22.08"W Longitude (WGS-84). The Alexandria Drafting Company (ADC) Washington County, Maryland Street Map Book, page and grid coordinate for the Site are 9 and K-5 & H-4, respectively.


|P a g e| 2

The Site is located in a rural area, but is in close proximity to urbanized development to the east of the Site. The Site is bordered to the north by Pennsylvania Route 163 (Mason Dixon Road), undeveloped agricultural land, and residences. The Site is bordered to the south by undeveloped agricultural land and residences. The Site is bordered to the east by residences and undeveloped agricultural land. The Site is bordered to the west by Greencastle Pike with undeveloped, agricultural land, residences, and a natural gas compressor station located beyond. The local surface topography and land features in the vicinity of the Site are more clearly illustrated on Figures 3 & 4.

The Site is segregated by a Norfolk Southern (NS) railway and a Utility Occupancy License will be required to cross the railway with the 34.5kV generation tie line. The railway crossing may be overhead or underground, but in any case the 34.5kV generation tie line will run underground from the western side of the NS railway to the breaker location near Greencastle Pike. The Site is also segregated by Daley Road and a Utility Permit and Utility Installation Bond will be required from the Washington County Division of Engineering & Construction Management to construct the underground 34.5kV generation tie line within the County right-of-way.

A new entrance is anticipated for breaker maintenance from Greencastle Pike, which is a State highway, at the northwestern corner of the Eby Property. Accordingly, an access permit will be required from the Maryland State Highway Administration (SHA) for access to the breaker. This will be in addition to the Highway Occupancy Permit from the Pennsylvania Department of Transportation (PennDOT) that is needed to access to the Array.

The Eby Property is accessible from Daley Road and Greencastle Pike and is traversed by a gravel farm lane that extends between these roadways. The Eby Property is a dairy farm operation. It contains a residential farm complex made up of a residential dwelling and multiple farm structures in the western portion of the property, and an additional barn and storage building located in the southeastern portion of the property. Lowell & Luella Eby and their family occupy and manage this property. These structures are not within the Project limits, i.e., the Site, and will be unaffected by the Project.

The Eby Property is not located within any special planning areas as designated by Washington County such as the Upper Beaver Creek Basin or the watershed boundaries of the Edgemont or Smithsburg Reservoirs. The Eby Property is not located within the Antietam Park or the Antietam Battlefield Overlay. The Eby Property is not located within 1,000 feet of the Appalachian Trail.

The Eby Property (Tax Map 10, Parcel 142) is zoned Agricultural (Rural) District. The Applicant applied to the Washington County Board of Zoning Appeals (BZA) and was granted a special exception for the Project under Docket No. AP2015-041 on January 6, 2016. Through further correspondence by the Applicant with Washington County, it was confirmed that the special exception applies to both the Array portion of the Project as well as the Interconnection portion of the Project.

The Eby Property is currently utilized for agricultural purposes and consists primarily of level to rolling agricultural fields and pasture. With the exception of a gravel farm lane, the Interconnection portion of the Site is devoid of any structures or improvements. There are no significant trees, tree cover, or forest cover on the Interconnection portion of the Site as defined by Maryland Natural Resources Section 5-1601 and the Washington County Forest Conservation Ordinance (FCO) Article 2. Only one sparse tree line is located along the eastern side of the NS railway on the Mason Dixon Property and the Applicant will seek to minimize any impacts to trees as a result of the Interconnection.


|P a g e| 3

The Interconnection portion of the Site, like the majority of the Array portion, is located in the Upper Potomac River Tributary Basin and is within the Conococheague Creek Watershed. The Interconnection portion of the Site, similar to the Array, also contains jurisdictional waters of the United States and waters of the State of Maryland, as one and the same, in the form of a channelized unnamed tributary (UNT) to Toms Run. This UNT to Toms Run consist of a non-relatively permanent waterway (non-RPW) that only sporadically conveys flow during the wet season and/or significant precipitation events as a result of sinkholes and karst topography. There is an existing pipe culvert crossing on the Eby Property where the gravel farm lane crosses the UNT to Toms Run. The jurisdictional waterways were identified at the overall Site by Triad Engineering, Inc. and verified by the Maryland Department of the Environment (MDE) during a Site meeting on June 15, 2016. No jurisdictional wetlands occur at the Site. A Report of Routine Wetland/Waterway Delineation Study for the Array and Interconnection is included as Appendix A.

According to Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map (FIRM) No. 240070 0080A, effective May 1, 1978, there is no FEMA mapped 100-year floodplain within the Property (see Figure 5). However, the Applicant is aware that the MDE regulates the 100-year water surface elevation of every jurisdictional waterway regardless of whether there is FEMA mapped 100-year floodplain present. On this basis, the UNT to Toms Run at the Site has a regulated 100-year water surface elevation.

With respect to the UNT to Toms Run and its associated 100-year water surface elevation, one perpendicular utility crossing is proposed for the Interconnection portion of the Project, which will require authorization from the Maryland Department of the Environment (MDE) and the U.S. Army Corps of Engineers (Corps). As indicated in the original ERD, a Nontidal Wetlands & Waterway Permit will be required from the MDE for utility and road crossings of UNTs to Toms Run for the Project. The applicant will submit a Joint Federal/State Application for the Alteration of any Floodplain, Waterway, Tidal or Nontidal Wetland in Maryland to the MDE Water Management Administration Regulatory Services Coordination Office to obtain the required authorizations as part of the development review process. For Category A activities, the MDE will typically issue their Nontidal Wetlands and Waterway Permit in conjunction with the Maryland State Programmatic General Permit (currently MDSPGP-5) authorization on behalf of the Corps.

Aside from the UNT to Toms Run, there are no know sensitive or critical habitat areas in relation to the Interconnection portion of the Project. The DNR – Wildlife & Heritage Division performed and Environmental Review for the Interconnection portion of the Project and issued a letter, dated May 12, 2016, which indicates that there are no official State or Federal records for listed plant or animals species. Correspondence from the DNR – Wildlife & Heritage Division for the Interconnection portion of the Project is included as Appendix B.

The modified interconnection configuration does not represent a material change to FE or PJM for the Project. The Project will still connect via a direct line tap to the 34.5 kV Halfway – Milnor circuit and the results of all interconnection studies performed to date continue to be valid. The only modifications required to study documents are to reflect that the interconnection facilities scope of work will now be completed by the Project. The System Impact Study was completed in September 2016, and the Facilities Study is currently underway, expected to be complete by July 2017. The latest System Impact Study is attached as Appendix C.

The Interconnection portion of the Project will entail new construction. No demolition or renovations of existing structures is required. Anticipated ground disturbances will be minimal and mostly temporary. The underground generation tie line will be open-cut and backfilled for compaction (except where crossing railroads or roadways) to depths as required by the National Electric Safety Code (NESC), National Electric Code (NEC), and any other applicable codes for this type of construction. Where heavy vehicular traffic is expected, the underground generation tie line will be encased in concrete


|P a g e| 4

or similar method of protection. Minimal cuts and/or fills may be required to install the breaker and access road; however, the total disturbance is expected to be less than 0.5 acres. There are no operation and maintenance facilities and no water or sewer requirements for the Interconnection portion of the Project. Overall, the Interconnection portion of the Project will be subject to the same or similar design and permitting process as the Array portion of the Project and they will be combined under one development review process.

In addition to a CPCN, the Project will require coverage under the MDE General National Pollutant Discharge Elimination System (NPDES) stormwater permit for construction activities over one acre, authorization from the MDE/Corps for utility and roadway stream crossings, a Highway Occupancy Permit from PennDOT, an Access Permit from the MSHA, and a Utility Occupancy License from NS. The Project will also require local grading, building, electrical, and utility permits from Washington County, Maryland.

SECTION II - STATEMENT OF NEED AND PURPOSE There are no changes to this section as a result of the proposed modification.

SECTION III - APPLICANT INFORMATION There are no changes to this section as a result of the proposed modification.

SECTION IV- STATE AND LOCAL PERMITS AND APPROVALS With the exception of what was previously discussed in Section I of this addendum and/or is discussed below, State and Local Permits and Approvals remain largely unchanged.

Interconnection Interconnection studies are largely complete, with the final Facilities Study expected in July of 2017. The new scope of work involves construction of the majority of the interconnection facilities by the Project, including the underground 34.5kV generation tie line and breaker per FE protection requirements. FE will construct air-break switches and one to two spans of overhead line from the point of interconnection on Greencastle Pike to the Project breaker location. FE has estimated that the work will take an estimated 12 months to complete. The Applicant expects to sign the Interconnection and Construction Service Agreements with FE and PJM in Q3 2017. Maryland State Highway Administration – Access Permit A new entrance is anticipated for breaker maintenance from Greencastle Pike, which is a State highway, at the northwestern corner of the Eby Property. Accordingly, an access permit will be required from the Maryland State Highway Administration (MSHA) for access to the breaker. The MSHA issues several types of permits for access and various construction activities or other work within the State road right-of-way. Access permit requirements may include access concept plans, traffic studies, detailed engineering plans, utility relocation plans, right-of-way dedications, conveyances, etc. The Applicant expects to address this requirement in conjunction with the local site plan review process, expected Q2/Q3 2017.


|P a g e| 5

Norfolk Southern - Utility Occupancy License The Properties are segregated by a NS railway and a Utility Occupancy License will be required to cross the railway with the electrical transmission line. NS has retained engineering service provider AECOM to receive the utility applications, review the plans, and handle the license agreements. To initiate the process the Applicant must fully complete an Application for Pipe or Wire Occupancy. The completed application and a non-refundable application and processing fee are required for handling. Upon receipt of the application and fee, AECOM will review the package for approval. AECOM will send the applicant an email confirming receipt of the package and the assigned NS Activity number for tracking purposes. If the application is complete and satisfactory, a utility license agreement will be drafted and forwarded to the applicant for signature approximately 4 weeks after receipt of the application. If additional information or revised engineering plans are required to develop a satisfactory proposal, an email requesting revisions will be sent to the applicant approximately 2-3 weeks after receipt of the application. After return of the partially executed agreement from the applicant, a fully executed agreement will be returned within approximately 2 weeks which will provide NS construction coordination contact information. The Applicant expects to submit an Application for Pipe or Wire Occupancy to AECOM during Q1 2017. Washington County – Utility Permit The Site is segregated by Daley Road. A Utility Permit and a Utility Installation Bond will be required from the Washington County Division of Engineering & Construction Management. The Applicant will address this as part of the local site plan review process, expected Q2/Q3 2017. A revised Summary of Permits/Approvals Table is presented below.

SECTION VI - COMAR 20.79.03.02 ENVIRONMENTAL INFORMATION With the exception of what was previously discussed in Section I of this addendum and/or is discussed below, the Environmental Information for the Project remains largely unchanged. The Eby Property contains one Maryland Inventory of Historic Properties listing which is identified as the Martin Farm (Survey No. WA-I-269). The Martin Farm listing is identified in the southwestern portion of the property and is for the stone-faced residence and frame bank barn, which is beyond the limits of the Site. The Maryland Historical Trust (MHT) has been consulted regarding the Array and Interconnection portions of the Project and their review has been comprehensive of both. Accordingly, MHT’s requirements and the Applicant’s actions remain unchanged. The Applicant is required to perform archaeological surveys of any areas of disturbance at the Site as well as perform Determinations of Eligibility for various named properties. As stated in the original ERD, the Applicant has engaged a qualified professional Cultural Resources Management (CRM) firm to address MHT’s recommendations and will continue to coordinate with the MHT to examine and review the Project for any potential impacts to cultural resources. The Applicant will provide updated information as it becomes available.

Mason Dixon Solar Center Washington County, Maryland Triad Project No. 03-15-0656

1.0 INTRODUCTION

Presented herein is a report summarizing the results of a Wetland/Waterway Delineation Study,

conducted by Triad Engineering, Inc. (Triad), for the Mason Dixon Solar Center located in

Washington County, Maryland. The purpose of this investigation was to identify, delineate, and

document jurisdictional waters of the U.S. and/or waters of the State, including wetlands, at the

site. This report outlines the results of our office analysis and site investigation.

The following terms and definitions are integral to this investigation:

1. Jurisdictional waters of the U.S.: Jurisdictional waters of the U.S. are currently defined as

traditional navigable waters; interstate waters, including interstate wetlands; the territorial seas; impoundments of traditional navigable waters, interstate waters, including interstate wetlands, the territorial seas, and tributaries, as defined, of such waters; tributaries, as defined, of traditional navigable waters, interstate waters, or the territorial seas and adjacent waters, including adjacent wetlands.

2. Waters of the State: Waters of the State include: (a) both surface and underground waters

within the boundaries of this State subject to its jurisdiction, including that part of the Atlantic Ocean within the boundaries of this State, the Chesapeake Bay and its tributaries, and all ponds, lakes, rivers, streams, tidal and nontidal wetlands, public ditches, tax ditches, and public drainage systems within this State, other than those designed and used to collect, convey, or dispose of sanitary sewage; and (b) the floodplain of free-flowing waters determined by the Department of Natural Resources on the basis of the 100-year flood frequency.

3. Ordinary High Water Mark (OHWM): The term ordinary high water mark means that line on

the shore established by the fluctuations of water and indicated by physical characteristics such as a clear, natural line impressed on the bank, shelving, changes in the character of soil, destruction of terrestrial vegetation, the presence of litter and debris, or other appropriate means that consider the characteristics of the surrounding areas.

4. Wetlands: Wetlands are defined as those areas that are inundated or saturated by surface

or ground water at a frequency and duration sufficient to support, and that under normal

Mason Dixon Solar Center Triad Engineering, Inc. Wetland/Waterway Delineation Study Triad Project No. 03-15-0656 June 10, 2016 Page 2

circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs, and similar areas.

5. Hydrophytic Vegetation: Hydrophytic vegetation is the sum total of macrophytic plant life

that occurs in areas where the frequency and duration of inundation or soil saturation produce permanently or periodically saturated soils of sufficient duration to exert a controlling influence on the plant species present.

6. Hydric Soils: Hydric soils are soils that formed under conditions of saturation, flooding, or

ponding long enough during the growing season to develop anaerobic conditions in the upper part. These soils, under natural conditions, are either saturated or inundated long enough during the growing season to support the growth and reproduction of hydrophytic vegetation.

7. Wetland Hydrology: Wetland Hydrology encompasses all hydrologic characteristics of

areas that are periodically inundated or have soils saturated to the surface at some time during the growing season.

8. Normal Circumstances: Normal circumstances are defined as the soil and hydrologic

conditions that are normally present, without regard to whether the vegetation has been removed. The determination of whether normal circumstances exist in a disturbed area involves an evaluation of the extent and relative permanence of the physical alteration of wetlands hydrology and hydrophytic vegetation and consideration of the purpose and cause of the physical alterations to hydrology and vegetation.

9. Atypical Situations: Atypical situations are areas in which indicators of one or more

wetland parameters have been obscured by some recent change or disturbance. More specifically, an atypical situation is when either (a) an alteration (removal or change) in the plant community has occurred such that a decision cannot be made using routine methods to determine if the site would support a prevalence of hydrophytic vegetation if undisturbed and no drainage action has occurred since December 23, 1985, or (b) a drainage action has occurred since December 23, 1985 that has altered the normal soil or hydrologic conditions.

10. Prior Converted Cropland: Prior converted cropland is defined as wetlands which were

both manipulated (drained or otherwise physically altered to remove excess water from the land) and cropped before December 23, 1985, to the extent that they no longer exhibit important wetland values. Specifically, prior converted cropland is inundated for no more than 14 consecutive days during the growing season. Prior converted cropland generally does not include pothole or playa wetlands. In addition, wetlands that are seasonally flooded or ponded for 15 or more consecutive days during the growing season are not considered prior converted cropland. Prior converted croplands generally have been subject to such extensive and relatively permanent physical hydrological modifications and alteration of hydrophytic vegetation that the resultant cropland constitutes the normal circumstances for


purposes of Section 404 jurisdiction. Consequently, the normal circumstances of prior converted croplands generally do not support a prevalence of hydrophytic vegetation and as such are not subject to regulation under Section 404.

11. Farmed Wetlands: Farmed wetlands are wetlands which were both manipulated and cropped before December 23, 1985, but which continue to exhibit important wetland values. Specifically, farmed wetlands include cropped potholes, playas, and areas with 15 or more consecutive days (or 10 percent of the growing season, whichever is less) of inundation during the growing season. Even though the vegetation has been removed by cropping, the basic soil and hydrological characteristics remain to the extent that hydrophytic vegetation would return if the cropping ceased. As such these areas are subject to regulation under Section 404.

12. Single and Complete Project: The term single and complete project is defined at 33 CFR

330.2(i) as the total project proposed or accomplished by one owner/developer or partnership or other association of owners/developers.

13. Independent Utility: The term independent utility in the Corps regulatory program refers to

a test that is used to determine what constitutes a single and complete project. A project is considered to have independent utility if it would be constructed absent the construction of other projects in the project area. Portions of a multi-phase project that depend upon other phases of the project do not have independent utility. Phases of a project that would be constructed even if the other phases were not built can be considered as separate single and complete projects with independent utility.

2.0 SITE AND PROJECT DESCRIPTION

Mason Dixon Solar Center (the Project) is a proposed utility scale solar electric generation

system (SEGS). The Project as proposed by Mason Dixon Solar Center, LLC (the Developer)

will be located on portions of two different properties (Tax Map 10, part of (p/o) Parcels 68 &

142), which are respectively owned by 2003 Mason Dixon, LLC and Lowell and Luella Eby (the

Landowners). The Project will occupy approximately 200 acres of land consisting primarily of

agricultural fields (the Site). The Site is segregated by a Norfolk Southern railway and Daley

Road.

The approximate 200-acre Site (Washington County Tax Map 10, p/o Parcels 68 & 142) is

located south of Pennsylvania Route 163 (Mason Dixon Road) and east of Maryland Route 63

(Greencastle Pike) in Washington County, Maryland (Latitude N 39.715962/Longitude W -

77.755022, Datum WGS 84). The Alexandria Drafting Company (ADC) Washington County,


Maryland Street Map Book, page and grid coordinate for the project site are 9 and H-4/K-5,

respectively. The properties are addressed as 17939 Mason Dixon Road and 14611

Greencastle Pike, Hagerstown, Maryland 21740.

The Site is located in the Upper Potomac River Tributary Basin and is within the Antietam Creek

Watershed (USGS Hydrological Unit Code 02140502) and the Conococheague Watershed

(Maryland 8-Digit Watershed Code 02140504). Antietam Creek and Conococheague Creek are

tributaries to the Potomac River. According to Code of Maryland Regulations (COMAR)

26.08.02.08 receiving waters in the vicinity of the Site are designated as USE IV-P -

Recreational Trout Waters and Public Water Supply. This class designation includes waters that

are public water supply and are capable of holding or supporting adult trout for put-and-take

fishing. In-stream construction is prohibited in Use IV-P waters from March 1 – May 31.

The Site is located in a rural area but is situated in the vicinity of a mixture of agricultural,

residential, and light commercial use land. The Site is bordered to the north by Pennsylvania

Route 163 (Mason Dixon Road), undeveloped agricultural land, and residences. The Site is

bordered to the south by undeveloped agricultural land and residences. The Site is bordered to

the east by residences and undeveloped agricultural land. The Site is bordered to the west by

Greencastle Pike with undeveloped, agricultural land, residences, and a natural gas compressor

station located beyond. The Site is segregated by a Norfolk Southern railway and Daley Road.

The local surface topography and land features in the vicinity of the site are more clearly

illustrated on the U.S. Geological Survey (USGS) 7.5-Minute Series Topographic Map attached

as Figure 1 and the 2015 aerial photograph attached as Figure 6. A copy of the Tax Map is

also attached as Figure 2.

The Project will consist of photovoltaic modules (solar panels) supported on fixed tilt support

frames or trackers. These solar panels will sit approximately 10 - 12 feet above the ground, and

will be arranged in rows spaced approximately eight feet apart. Minimal ground disturbances

will be required for the project because the solar panels, for the most part, will follow the site

topography and be constructed on existing grades. Minor earth disturbances will be required to

construct foundation systems, access roads, the electrical collection system, and perimeter

fencing. There are no planned operations and/or maintenance facilities as part of this Project.

There are no water and/or sewer requirements for the Project.


3.0 OFF-SITE ANALYSIS

The applicable portions of the Mason-Dixon, Maryland (1971) and Hagerstown, Maryland (1999)

USGS 7.5-Minute Series Topographic Maps are included as Figure 1. The USGS topographic

maps identify two surface water features at the Site consisting of unnamed tributaries (UNTs) to

Toms Run.

According to the U.S. Fish & Wildlife Service (FWS) National Wetland Inventory (NWI) map and

the Maryland Department of Natural Resources (DNR) wetland map, there are no wetland

habitats at the Site. The NWI Map that was produced for the Site is included as Figure 3 and

the DNR Wetland Map is included as Figure 4.

According to the United States Department of Agriculture (USDA) National Resources

Conservation Service (NRCS) Custom Soil Resource Report for Washington County, Maryland,

the soils at the Site are a mix of Funkstown, Hagerstown, Lindside, Melvin, Swanpond and

Swanpond-Funkstown series soils. With the exception of the Melvin soil units which are

classified as poorly drained, most of the soil units within the Site are listed as well-drained or

moderately well-drained. Melvin soil units are also classified as having frequent flooding with no

frequency of ponding while the remaining soil units are listed as having no frequency of flooding

or ponding. There are two listed hydric soil types within the site consisting of Ln – Lindside silt

loam and Me – Melvin silt loam. These soil units are identified in association with the

channelized UNTs to Toms Run at the site. A USDA NRCS Custom Soil Resource Report for

the site is included as Appendix 2.

According to Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map

(FIRM) No. 240070 0080A, effective May 1, 1978, there is no FEMA mapped 100-year

floodplain within the site. It should be noted however; that the Maryland Department of the

Environment (MDE) regulates the 100-year water surface elevation of every jurisdictional

waterway regardless of whether there is FEMA mapped 100-year floodplain present. On this

basis, the UNTs to Toms Run at the site will have a regulated 100-year water surface elevation,

which may have to be determined through a Hydrology and Hydraulics Analysis. A FIRMette for

the site is included as Figure 5.


4.0 ON-SITE INSPECTION

Patrick Upham and Tim Kellerman of Triad conducted on-site investigations at the site on

December 16, 2015 and April 26, 2016. The physical condition of the site at these times was

typical for the time of year. During the on-site investigation, the site was accessed and

inspected on foot and the interior of the overall site was examined for the presence of

jurisdictional waters of the U.S., including wetlands. Photographs documenting site conditions

at the time of the on-site investigation are included as Appendix 3.

5.0 METHODOLOGY

This evaluation was performed in general accordance with the Routine and Atypical Wetland

Determination Methods as outlined in the U.S. Army Corps of Engineers (Corps) Wetlands

Delineation Manual (Y-87-1), dated January 1987, and the Interim Regional Supplement to the

Corps of Engineers Wetland Delineation Manual: Eastern Mountains and Piedmont Region

(ERDC/EL TR-12-9), dated April 2012.

Wetlands identified during this investigation have been classified in general accordance with the

Cowardin system. The Cowardin system is a comprehensive classification system of wetlands

and deepwater habitats that was developed for the U.S. Fish and Wildlife Service. The

Cowardin system is hierarchical and includes several layers of detail for wetland classification

including: a subsystem of water flow; classes of substrate types; subclasses of vegetation types

and dominant species; as well as flooding regimes and salinity levels for each system.

6.0 FINDINGS

Channelized UNTs to Toms Run resembling linear agricultural ditches were identified at the

Site. These UNTs to Toms Run consist of non-relatively permanent waterways (non-RPWs)

that only sporadically convey flow during the wet season and/or significant precipitation events

as a result of sinkholes and karst topography. Typical stream characteristics, including an

OHWM, are not readily apparent; rather these waterways are dominated by terrestrial

vegetation. Despite this, these UNTs to Toms Run have been identified as jurisdictional as they

sometimes convey ground and surface waters and they have a nexus to a traditional navigable

waterway (TNW).


Upland conditions were observed throughout the remainder of the Site. With the exception of

aforementioned jurisdictional waterways, the Site consists of livestock grazed pasture and

agricultural cropland that would be considered non-wetlands. Specific soil types, which are

mapped by the soil survey in the area of the Site, are discussed in Section 3.0 of this report.

Based on a visual inspection of soil profiles with the aid of a Munsell Soil Color Book, the soils

over the remainder of the Site did not exhibit common indicators of hydric soils but instead,

exhibited characteristics of upland soils. With the exception of surface saturation from

precipitation and erosion from stormwater runoff; positive wetland hydrology indicators were

likewise absent from the remainder of the Site.

7.0 CONCLUSIONS AND RECOMMENDATIONS

In conclusion, Triad performed a Wetland/Waterway Delineation Study, which consisted of an

off-site, office analysis and an on-site inspection using the atypical and routine approaches as

outlined in the Corps 1987 Wetlands Delineation Manual to identify, delineate, and document

jurisdictional waters of the U.S. and waters of the State, including wetlands, at the Site. As a

result of this investigation, it is our conclusion that jurisdictional waters of the U.S. and waters of

the State, as one and the same, are present at the Site in the form of UNTs to Toms Run.

These jurisdictional areas within the Site are shown on the Wetland/Waterway Delineation Plan

is included as Appendix 4. No Wetland Determination Data Forms were prepared as part of

this investigation, since no suspect wetlands were encountered.

Several important concepts should be considered prior to proposing or applying for

authorization to impact jurisdictional waters of the U.S. and/or waters of the State, including

wetlands. These concepts are universal among the authorities that regulate jurisdictional

wetlands and waterways and must be demonstrated by the applicant to effectively and

efficiently negotiate the permitting process. First and foremost, an applicant must demonstrate

that there are no alternatives and that all appropriate and practicable avoidance and

minimization measures have been considered. Second, it must be demonstrated that the

proposed activity will not directly or indirectly affect rare, threatened, and/or endangered

species, historic properties, or archaeological sites. Third, the concept of a “single and

complete project” must be considered to ensure that an issued permit is comprehensive and


applies to all of the proposed impacts to jurisdictional waters of the U.S. and/or waters of the

State, including wetlands, which could occur as part of a defined Project.

If temporary or permanent impacts are anticipated to jurisdictional waters of the U.S. and/or

waters of the State, including wetlands, the 25-foot wide wetland buffer, and/or the 100-year

floodplain, a Joint Federal/State Permit Application (JPA) must be submitted to the MDE

Regulatory Services Coordination Office (RSC). The RSC will determine what type of

authorization is necessary and will forward the application to the appropriate agencies.

Impacts to jurisdictional waters of the U.S. and waters of the state, as one and the same, will

require authorization from both the Corps and the MDE. The Corps has issued a programmatic

general permit in Maryland (MDSPGP-4, effective October 1, 2011), which is a federal Section

404 permit, for unavoidable construction activities in jurisdictional waters of the U.S., including

wetlands. This statewide general permit replaces Nationwide Permits (NWPs) and Regional

General Permits (RGPs) for most types of work. The MDSPGP-4 applies to the discharge of

dredged or fill material and/or the placement of structures, that are components of a single and

complete project, including all attendant features both temporary and/or permanent, which

individually and/or cumulatively result in direct or indirect impacts not to exceed 1.0 acre (43,560

square feet) of waters of the U.S., including wetlands and/or 2,000 linear feet of streams, for

specific categories of activities as regulated by Section 404 of the CWA and/or Section 10 of the

Rivers and Harbors Act of 1899. Category A activities that have only minimal individual and

cumulative adverse effects on the environment (less than 5,000 square feet and/or 200 linear

feet) will not require a review by the Corps. Category A activates are usually reviewed and

authorized by the MDE alone on the Corps behalf. Category B activities on the other hand will

be reviewed and verified by the MDE and the Corps along with appropriate resource agencies

to determine whether such activities may be authorized under the MDSPGP-4. If the project

impacts will exceed the maximum acreage and/or linear limits of the MDSPGP-4, an individual

Section 404 permit (IP) will be required from the Corps. Standard IPs are issued for activities

that have more than minimal adverse impacts to waters of the U.S. and evaluation of each

permit application involves a more thorough review of the potential environmental and

socioeconomic effects of the proposed activity. The MDE will generally issue a Nontidal

Wetlands and Waterways Permit in conjunction with the MDSPGP or IP.


Impacts to only waters of the State, including wetlands, the 25-foot wide wetland buffer, and/or

100-year floodplain, will be authorized by MDE alone via a Nontidal Wetlands and Waterway

Permit or a Letter of Exemption, unless exempted by regulation. Activities that require only a

Letter of Exemption include: repair of serviceable water control structures; activities in isolated

nontidal wetlands of less than one acre and having no significant plant or wildlife value; activities

having a cumulative loss of less than 5,000 square feet of nontidal wetlands, and 25-foot buffer,

containing no significant plant or wildlife value; installation of overhead and underground utility

lines; and an entire and complete project that impacts less than two acres of farmed nontidal

wetlands given that the nontidal wetlands are inundated for 15 or more consecutive days during

the growing season.

When authorizations are issued for activities which will cause unavoidable losses of nontidal

wetlands, the losses must be countered with wetland gains to meet the “no net loss” goal. The

primary means of accomplishing wetland gains is through wetland mitigation. Nontidal wetland

mitigation is the creation, restoration, or enhancement of nontidal wetlands, to compensate for

nontidal wetlands that were or will be lost due to regulated activities or non-exempt agricultural

activities. The State definition of mitigation corresponds to the Federal definition of

compensatory mitigation. Mitigation is not required for temporary impacts to wetlands or

impacts to the wetland buffer or expanded buffer. Compensatory mitigation is generally

required for all wetland impacts greater than 1/10 acre and/or stream bed impacts greater than

200 linear feet. Noteworthy, is that once the 1/10 acre wetland threshold or the 200 linear foot

stream threshold is exceeded, compensatory mitigation is required for all proposed impacts.

Compensatory mitigation ratios for wetland impacts are generally 2:1 for forested wetlands;

1.5:1 for scrub-shrub wetlands; and 1:1 for emergent wetlands. Compensatory mitigation

requirements for stream impacts, when required, are generally determined on a case-by-case

basis.

8.0 LIMITATIONS

This investigation and report have been prepared specifically for the Site by Triad for the use of

the addressee, their authorized representatives, and their successors and assigns under the

terms and limitations of our proposal and general conditions. The work on this project has been


carried out in accordance with reasonable and acceptable environmental practices. No other

warranty, either written or implied, is applicable to this project.

Our opinions and conclusions were based on observations from a point in time; however, the

environmental parameters associated with wetlands and waterways are continually changing

over time due to both natural and anthropogenic occurrences. Therefore, site conditions are

likely to vary over time from those encountered during our investigation. This is especially true

for sites surrounded by ongoing development, sites undergoing improvements, or sites in

agricultural production. Specifically sites in agricultural production may contain “Farmed

Wetlands” and/or “Prior Converted Cropland” that were not recognizable as wetlands at the time

of our investigation. These areas may develop more distinguishable wetland characteristics

and/or revert to wetlands when the agricultural practice ceases or the method previously utilized

to drain “Prior Converted Cropland” fails.

Due to the fact that wetlands and waterways are ecological transition zones, the accuracy with

which they can be delineated is limited. Boundaries may also change over time due to

continually changing conditions in the environment and as such, Triad cannot assume

responsibility for their changing conditions. In addition, the evaluation of wetland parameters is

subjective and regulatory personnel may interpret conditions differently based on their

experience level and perspective and/or a different point in time. On this basis, our opinions

and conclusions expressed herein represent our best professional judgment and are reflective

of the site conditions at the time of our investigations.

According to the Code of Federal Regulations (CFR), the Corps has the authority to determine

what is regulated under Section 9 and 10 of the Rivers and Harbors Act of 1899 and Section

404 of the Clean Water Act. Similarly, the MDE has authority under the Nontidal Wetlands

Protection Act. The Nontidal Wetlands Protection Act regulates and restricts all activities that

could impact waters of the State. The act also helps to ensure “no net loss” of wetlands by

requiring mitigation or compensation for any wetland losses. This law differs from federal

regulation on issues of “isolated” wetlands, the alteration of vegetation and hydrology, and

regulation of a 25-foot buffer. In Maryland, buffer requirements are expanded to 100-foot for

“nontidal wetlands of special State concern,” which have been designated by regulation as


having exceptional ecological or educational value. As such, our conclusions expressed herein

should not be considered final until validated by the Corps and/or the MDE.

We appreciate the opportunity to provide our services on this project. Should you have any

PrefaceSoil surveys contain information that affects land use planning in survey areas. Theyhighlight soil limitations that affect various land uses and provide information aboutthe properties of the soils in the survey areas. Soil surveys are designed for manydifferent users, including farmers, ranchers, foresters, agronomists, urban planners,community officials, engineers, developers, builders, and home buyers. Also,conservationists, teachers, students, and specialists in recreation, waste disposal,and pollution control can use the surveys to help them understand, protect, or enhancethe environment.

Various land use regulations of Federal, State, and local governments may imposespecial restrictions on land use or land treatment. Soil surveys identify soil propertiesthat are used in making various land use or land treatment decisions. The informationis intended to help the land users identify and reduce the effects of soil limitations onvarious land uses. The landowner or user is responsible for identifying and complyingwith existing laws and regulations.

Although soil survey information can be used for general farm, local, and wider areaplanning, onsite investigation is needed to supplement this information in some cases.Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/portal/nrcs/main/soils/health/) and certain conservation and engineering applications. Formore detailed information, contact your local USDA Service Center (http://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State SoilScientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/?cid=nrcs142p2_053951).

Great differences in soil properties can occur within short distances. Some soils areseasonally wet or subject to flooding. Some are too unstable to be used as afoundation for buildings or roads. Clayey or wet soils are poorly suited to use as septictank absorption fields. A high water table makes a soil poorly suited to basements orunderground installations.

The National Cooperative Soil Survey is a joint effort of the United States Departmentof Agriculture and other Federal agencies, State agencies including the AgriculturalExperiment Stations, and local agencies. The Natural Resources ConservationService (NRCS) has leadership for the Federal part of the National Cooperative SoilSurvey.

Information about soils is updated periodically. Updated information is availablethrough the NRCS Web Soil Survey, the site for official soil survey information.

How Soil Surveys Are MadeSoil surveys are made to provide information about the soils and miscellaneous areasin a specific area. They include a description of the soils and miscellaneous areas andtheir location on the landscape and tables that show soil properties and limitationsaffecting various uses. Soil scientists observed the steepness, length, and shape ofthe slopes; the general pattern of drainage; the kinds of crops and native plants; andthe kinds of bedrock. They observed and described many soil profiles. A soil profile isthe sequence of natural layers, or horizons, in a soil. The profile extends from thesurface down into the unconsolidated material in which the soil formed or from thesurface down to bedrock. The unconsolidated material is devoid of roots and otherliving organisms and has not been changed by other biological activity.

Currently, soils are mapped according to the boundaries of major land resource areas(MLRAs). MLRAs are geographically associated land resource units that sharecommon characteristics related to physiography, geology, climate, water resources,soils, biological resources, and land uses (USDA, 2006). Soil survey areas typicallyconsist of parts of one or more MLRA.

The soils and miscellaneous areas in a survey area occur in an orderly pattern that isrelated to the geology, landforms, relief, climate, and natural vegetation of the area.Each kind of soil and miscellaneous area is associated with a particular kind oflandform or with a segment of the landform. By observing the soils and miscellaneousareas in the survey area and relating their position to specific segments of thelandform, a soil scientist develops a concept, or model, of how they were formed. Thus,during mapping, this model enables the soil scientist to predict with a considerabledegree of accuracy the kind of soil or miscellaneous area at a specific location on thelandscape.

Commonly, individual soils on the landscape merge into one another as theircharacteristics gradually change. To construct an accurate soil map, however, soilscientists must determine the boundaries between the soils. They can observe onlya limited number of soil profiles. Nevertheless, these observations, supplemented byan understanding of the soil-vegetation-landscape relationship, are sufficient to verifypredictions of the kinds of soil in an area and to determine the boundaries.

Soil scientists recorded the characteristics of the soil profiles that they studied. Theynoted soil color, texture, size and shape of soil aggregates, kind and amount of rockfragments, distribution of plant roots, reaction, and other features that enable them toidentify soils. After describing the soils in the survey area and determining theirproperties, the soil scientists assigned the soils to taxonomic classes (units).Taxonomic classes are concepts. Each taxonomic class has a set of soilcharacteristics with precisely defined limits. The classes are used as a basis forcomparison to classify soils systematically. Soil taxonomy, the system of taxonomicclassification used in the United States, is based mainly on the kind and character ofsoil properties and the arrangement of horizons within the profile. After the soilscientists classified and named the soils in the survey area, they compared the

5

individual soils with similar soils in the same taxonomic class in other areas so thatthey could confirm data and assemble additional data based on experience andresearch.

The objective of soil mapping is not to delineate pure map unit components; theobjective is to separate the landscape into landforms or landform segments that havesimilar use and management requirements. Each map unit is defined by a uniquecombination of soil components and/or miscellaneous areas in predictableproportions. Some components may be highly contrasting to the other components ofthe map unit. The presence of minor components in a map unit in no way diminishesthe usefulness or accuracy of the data. The delineation of such landforms andlandform segments on the map provides sufficient information for the development ofresource plans. If intensive use of small areas is planned, onsite investigation isneeded to define and locate the soils and miscellaneous areas.

Soil scientists make many field observations in the process of producing a soil map.The frequency of observation is dependent upon several factors, including scale ofmapping, intensity of mapping, design of map units, complexity of the landscape, andexperience of the soil scientist. Observations are made to test and refine the soil-landscape model and predictions and to verify the classification of the soils at specificlocations. Once the soil-landscape model is refined, a significantly smaller number ofmeasurements of individual soil properties are made and recorded. Thesemeasurements may include field measurements, such as those for color, depth tobedrock, and texture, and laboratory measurements, such as those for content ofsand, silt, clay, salt, and other components. Properties of each soil typically vary fromone point to another across the landscape.

Observations for map unit components are aggregated to develop ranges ofcharacteristics for the components. The aggregated values are presented. Directmeasurements do not exist for every property presented for every map unitcomponent. Values for some properties are estimated from combinations of otherproperties.

While a soil survey is in progress, samples of some of the soils in the area generallyare collected for laboratory analyses and for engineering tests. Soil scientists interpretthe data from these analyses and tests as well as the field-observed characteristicsand the soil properties to determine the expected behavior of the soils under differentuses. Interpretations for all of the soils are field tested through observation of the soilsin different uses and under different levels of management. Some interpretations aremodified to fit local conditions, and some new interpretations are developed to meetlocal needs. Data are assembled from other sources, such as research information,production records, and field experience of specialists. For example, data on cropyields under defined levels of management are assembled from farm records and fromfield or plot experiments on the same kinds of soil.

Predictions about soil behavior are based not only on soil properties but also on suchvariables as climate and biological activity. Soil conditions are predictable over longperiods of time, but they are not predictable from year to year. For example, soilscientists can predict with a fairly high degree of accuracy that a given soil will havea high water table within certain depths in most years, but they cannot predict that ahigh water table will always be at a specific level in the soil on a specific date.

After soil scientists located and identified the significant natural bodies of soil in thesurvey area, they drew the boundaries of these bodies on aerial photographs andidentified each as a specific map unit. Aerial photographs show trees, buildings, fields,roads, and rivers, all of which help in locating boundaries accurately.

Your area of interest (AOI) includes more than one soil survey area.These survey areas may have been mapped at different scales, witha different land use in mind, at different times, or at different levelsof detail. This may result in map unit symbols, soil properties, andinterpretations that do not completely agree across soil survey areaboundaries.

Soil map units are labeled (as space allows) for map scales 1:50,000or larger.

Date(s) aerial images were photographed: Apr 14, 2011—Nov 6,2011

The orthophoto or other base map on which the soil lines werecompiled and digitized probably differs from the backgroundimagery displayed on these maps. As a result, some minor shiftingof map unit boundaries may be evident.

Map Unit DescriptionsThe map units delineated on the detailed soil maps in a soil survey represent the soilsor miscellaneous areas in the survey area. The map unit descriptions, along with themaps, can be used to determine the composition and properties of a unit.

A map unit delineation on a soil map represents an area dominated by one or moremajor kinds of soil or miscellaneous areas. A map unit is identified and namedaccording to the taxonomic classification of the dominant soils. Within a taxonomicclass there are precisely defined limits for the properties of the soils. On the landscape,however, the soils are natural phenomena, and they have the characteristic variabilityof all natural phenomena. Thus, the range of some observed properties may extend


10

beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomicclass rarely, if ever, can be mapped without including areas of other taxonomicclasses. Consequently, every map unit is made up of the soils or miscellaneous areasfor which it is named and some minor components that belong to taxonomic classesother than those of the major soils.

Most minor soils have properties similar to those of the dominant soil or soils in themap unit, and thus they do not affect use and management. These are callednoncontrasting, or similar, components. They may or may not be mentioned in aparticular map unit description. Other minor components, however, have propertiesand behavioral characteristics divergent enough to affect use or to require differentmanagement. These are called contrasting, or dissimilar, components. They generallyare in small areas and could not be mapped separately because of the scale used.Some small areas of strongly contrasting soils or miscellaneous areas are identifiedby a special symbol on the maps. If included in the database for a given area, thecontrasting minor components are identified in the map unit descriptions along withsome characteristics of each. A few areas of minor components may not have beenobserved, and consequently they are not mentioned in the descriptions, especiallywhere the pattern was so complex that it was impractical to make enough observationsto identify all the soils and miscellaneous areas on the landscape.

The presence of minor components in a map unit in no way diminishes the usefulnessor accuracy of the data. The objective of mapping is not to delineate pure taxonomicclasses but rather to separate the landscape into landforms or landform segments thathave similar use and management requirements. The delineation of such segmentson the map provides sufficient information for the development of resource plans. Ifintensive use of small areas is planned, however, onsite investigation is needed todefine and locate the soils and miscellaneous areas.

An identifying symbol precedes the map unit name in the map unit descriptions. Eachdescription includes general facts about the unit and gives important soil propertiesand qualities.

Soils that have profiles that are almost alike make up a soil series. Except fordifferences in texture of the surface layer, all the soils of a series have major horizonsthat are similar in composition, thickness, and arrangement.

Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity,degree of erosion, and other characteristics that affect their use. On the basis of suchdifferences, a soil series is divided into soil phases. Most of the areas shown on thedetailed soil maps are phases of soil series. The name of a soil phase commonlyindicates a feature that affects use or management. For example, Alpha silt loam, 0to 2 percent slopes, is a phase of the Alpha series.

Some map units are made up of two or more major soils or miscellaneous areas.These map units are complexes, associations, or undifferentiated groups.

A complex consists of two or more soils or miscellaneous areas in such an intricatepattern or in such small areas that they cannot be shown separately on the maps. Thepattern and proportion of the soils or miscellaneous areas are somewhat similar in allareas. Alpha-Beta complex, 0 to 6 percent slopes, is an example.

An association is made up of two or more geographically associated soils ormiscellaneous areas that are shown as one unit on the maps. Because of present oranticipated uses of the map units in the survey area, it was not considered practicalor necessary to map the soils or miscellaneous areas separately. The pattern andrelative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example.


11

An undifferentiated group is made up of two or more soils or miscellaneous areas thatcould be mapped individually but are mapped as one unit because similarinterpretations can be made for use and management. The pattern and proportion ofthe soils or miscellaneous areas in a mapped area are not uniform. An area can bemade up of only one of the major soils or miscellaneous areas, or it can be made upof all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.

Some surveys include miscellaneous areas. Such areas have little or no soil materialand support little or no vegetation. Rock outcrop is an example.

Easement Lands for Mason Dixon Solar Center, LLC Lowell and Luella Eby Property (Tax Map 10, Parcel 142) 14611 Greencastle Pike Hagerstown, Washington County, Maryland Triad Project No. 03-15-0656

Dear Ms. Byrne:

Triad Engineering, Inc. (Triad) is requesting an environmental review for the above-referenced property. As part of this, we respectfully request any information your agency maintains with respect to Federal or State rare, threatened, and/or endangered species at this property. In addition, we are requesting a written response outlining any and all regulatory requirements that your agency would anticipate in relation to the construction of an overhead or underground electrical utility line at this property.

Project Description, Purpose, and Need

The approximate 139-acre site (Tax Map 10, Parcel 142) is located between the eastern side of Greencastle Pike (Maryland Route 63) and along the eastern and western sides of Daley Road in Washington County, Maryland. The site is addressed as 14611 Greencastle Pike, Hagerstown, Maryland 21740. The approximate center of the site is located at approximately 39° 42' 57.83" N Latitude and 77° 45' 41.54" W Longitude (WGS-84). The Alexandria Drafting Company (ADC) Washington County, Maryland Street Map Book, page and grid coordinate for the project site are 9 and H-4, respectively. The project site primarily consists of agricultural fields with a residential farm complex located in the western portion of the site. The site location and extent are more clearly shown on the attached figures.

The project will consist of an overhead or underground electric utility line that will extend from the previously reviewed Mason Dixon Solar Center, LLC property to an existing overhead electric line located along Greencastle Pike, which will serve as the interconnection point for the

Mason Dixon Solar Center, LLC utility scale solar project. The Mason Dixon Solar Center, LLC property was previously reviewed by your office in December 2015. According to your response, dated December 24, 2015, no State or Federal records for rare, threatened, or endangered species were identified in association with Mason Dixon Solar Center, LLC property. This request is for the adjoining property which will be affected by the electric transmission line, which will connect the Mason Dixon Solar Center to the electrical grid.

Proposed Easement Lands for Mason Dixon Solar Center, LLC – Environmental Review Request RE: Triad Project No. 03-15-0656 May 2, 2016 Page 2 There is no known federal or state funding associated with this project. It will require a Certificate of Public Convenience and Necessity (CPCN) from the Maryland Public Service Commission (PSC). It will also require coverage under the Maryland Department of the Environment (MDE) General NPDES stormwater permit for construction activities over one acre. Finally it is anticipated that the project will require local entrance, building, and grading permits from Washington County, Maryland.

In closing, we hope that we have provided adequate information for you to perform your review. If you have any questions or require any additional information, please do not hesitate to contact us. We look forward to your response.

Sincerely,

TRIAD ENGINEERING, INC.

( Revised )

October 2016

© PJM Interconnection 2016. All rights reserved. 2 AB1-123 Showalter 34.5 kV

Preface The intent of the System Impact Study is to determine a plan, with approximate cost and

construction time estimates, to connect the subject generation interconnection project to the PJM

network at a location specified by the Interconnection Customer. As a requirement for

interconnection, the Interconnection Customer may be responsible for the cost of constructing:

Network Upgrades, which are facility additions, or upgrades to existing facilities, that are needed

to maintain the reliability of the PJM system. All facilities required for interconnection of a

generation interconnection project must be designed to meet the technical specifications (on PJM

web site) for the appropriate transmission owner.

In some instances an Interconnection Customer may not be responsible for 100% of the

identified network upgrade cost because other transmission network uses, e.g. another generation

interconnection or merchant transmission upgrade, may also contribute to the need for the same

network reinforcement. The possibility of sharing the reinforcement costs with other projects

may be identified in the Feasibility Study, but the actual allocation will be deferred until the

System Impact Study is performed.

The System Impact Study estimates do not include the feasibility, cost, or time required to obtain

property rights and permits for construction of the required facilities. The project developer is

responsible for the right of way, real estate, and construction permit issues. For properties

currently owned by Transmission Owners, the costs may be included in the study.

General Mason Dixon Solar Center, LLC (“Interconnection Customer”) has proposed a solar generating

facility located at 17939 Mason Dixon Rd, Hagerstown, Washington County, MD. The installed

facilities will have a total capability of 18.4 MW with 7.0 MW of this output being recognized

by PJM as capacity. The proposed in-service date for this project is July 1, 2017. This study

does not imply a Potomac Edison (“Transmission Owner”) commitment to this in-service

date.

Point of Interconnection

AB1-123 will interconnect with the Potomac Edison transmission system by tapping the Halfway

– Milnor 34.5 kV line. Please refer to the one-line diagram in Appendix 2 for system

configuration.

Interconnection Customer Requirements In addition to the Potomac Edison facilities, Mason Dixon Solar Center, LLC will also be

responsible for meeting all criteria as specified in the applicable sections of the FirstEnergy

“Requirements for Transmission Connected Facilities" document including:

1. The purchase and installation of fully rated interrupting device on the high side of the (AB1-

123) step-up transformer.

2. The purchase and installation of the minimum required FirstEnergy generation

interconnection relaying and control facilities. This includes over/under voltage protection,

over/under frequency protection, and zero sequence voltage protection relays.

3. The purchase and installation of supervisory control and data acquisition (“SCADA”)

equipment to provide information in a compatible format to the FirstEnergy Transmission

System Control Center.

4. The establishment of dedicated communication circuits for SCADA to the FirstEnergy

Transmission System Control Center.

5. A compliance with the FirstEnergy and PJM generator power factor and voltage control

requirements.

6. The execution of a back-up retail service agreement with the electric distribution company to

serve the customer load supplied from the (AB1-123) generation project interconnection point

when the units are out-of-service.

The above requirements are in addition to any metering or other requirements imposed by PJM.

Revenue Metering and SCADA Requirements

PJM Requirements

The Interconnection Customer will be required to install equipment necessary to provide

Revenue Metering (KWH, KVARH) and real time data (KW, KVAR) for Interconnection

Customer’s generating Resource. See PJM Manuals M-01 and M-14D, and PJM Tariff Sections

24.1 and 24.2.

Interconnected Transmission Owner Requirements

The Interconnection Customer will be required to comply with all FirstEnergy Revenue Metering

Requirements for Generation Interconnection Customers. The Revenue Metering Requirements

may be found within the “FirstEnergy Requirements for Transmission Connected Facilities”

document located at the following links:

http://www.firstenergycorp.com/feconnect

http://www.pjm.com/planning/design-engineering/to-tech-standards.aspx




Schedule Based on the scope of Attachment Facilities and Network Upgrades required to support the this

generation project, it is expected to take a minimum of thirteen (13) months from the date of a

fully executed Interconnection Construction Service Agreement to complete the installation. It

also assumes that Interconnection Customer will provide all rights-of-way, permits, easements,

etc. that will be needed. A further assumption is that there will be no environmental issues with

any of the new properties associated with this project, that there will be no delays in acquiring

the necessary permits for implementing the defined Direct and Non-Direct Network upgrades,

and that all system outages will be allowed when requested.

Other Supporting Facilities Charge Subject to any required regulatory approvals or acceptance, the IC shall pay to PE a monthly

charge of $27,378 for the connection of the customer facility to the PJM transmission system via

the distribution system. The monthly charge will be part of Attachment H of the PJM OATT for

this specific interconnection. Such charge may be billed to, and collected from the IC on behalf

of PE by PJM and may be adjusted from time to time in accordance with Applicable Laws and

Regulations.


Network Impacts The Queue Project AB1-123 was evaluated as a 18.4 MW (Capacity 7.0 MW) injection into the

Halfway 34.5 kV substation in the APS area. Project AB1-123 was evaluated for compliance

with applicable reliability planning criteria (PJM, NERC, NERC Regional Reliability Councils,

and Transmission Owners). Project AB1-123 was studied with a commercial probability of

100%. Potential network impacts were as follows:

Delivery of Energy Portion of Interconnection Request

PJM also studied the delivery of the energy portion of this interconnection request. Any

problems identified below are likely to result in operational restrictions to the project under

study. The developer can proceed with network upgrades to eliminate the operational restriction

at their discretion by submitting a Merchant Transmission Interconnection request.

Only the most severely overloaded conditions are listed. There is no guarantee of full delivery of

energy for this project by fixing only the conditions listed in this section. With a Transmission


Interconnection Request, a subsequent analysis will be performed, which will study all overload

conditions associated with the overloaded element(s) identified.
