301.86 As defined by the Soil Conservation Service, how much price or unique agricultural land exists on the following sites: Moore, Comerford, Errol, and Bear Swamp?

RESPONSE. Bear Swamp Site (MA)

A detailed analysis of the Soil Survey f or Franklin County, Massachusetts, and state classifica tion of prime and unique farmlands indicates that no agricultural lands considered to be prime or unique exist on the Bear Swamp site.

Errol Site (NH)

No soils considered to be prime farmland types cre known to be present on the Errol site. Although no recent soil surveys have been conducted, there appears to be a good correlation to the older survey. No lands of unique classification exist on site as well.

Moore Site ( NH)

A preliminary analysis of the soils of the Moore site has indicated that no f armland soils class ified as prime or unique are present.

Comerford Site (NH)

A preliminary analysis of the soils of the Comerford site indicates that prime farmland soil types do occur on the site along an extension of property southeast of Route 135 (ER Figure 9.2-7). The prime f armland soil and its estimated acreage is listed below:

Name Acre a ge Berkshire loam 50-75 No soils or habitat classified as unique occur on the Comerford site according to references.

301.87 Please identify the Federal and Stat .isted rare, threatened, and endangered plant and animal species likely to be impacted by construction and operation of the plant using the Moore, Comerford, Errol, and Bear Swamp sites.

RESPONSE: Bear Swamp Site (mal Applicant conducted a site survey in July 1977. Using this inf ormation with an analysis of both S tate and Federal listings shows that no species of flora oc f auna considered to be threatened or endangered would be impacted by the construction of a power f acility at this site.

Moore Site (NH), Come rf o rd S it e_(Nil) . Erroi Site (NID_

Preliminary evaluations of these sites indicate that no species of fauna considered to be threatened or endangered would receive an impact from plant construction. Area habitat evaluations indicate as well, that no species of threatened or endangered flora would be af fected by plant cons truc t ion .

301.88 As defined by the De p.i r t me n t of Housing and Urban Development, identif y those candidate siter which are located within a floodplain.

RESPONSE: Applicant investigated potential floodplain areas, as defined and designated by the Department of Housing and Urban Development, during December 1978. Additionally, as sug;;e s t ed by HUD pe rsonnel, New llampshire, Massachusetts and Rhode Island State Coordinators of the Fede ral Insurance Administ rat ion

( FI A) were contacted. Inf o rmat ion obt ained f rom these agencies is included below. The site areas are desi;nated t on ER Figures 301.88-1 through 301.88-7 to provide a concise presentation.

!!oore Pond Site (Nil)

The Moore Pond site is not in a designated floodplain area.

A flood hazard boundary map prepared by FIA (ER Figure 301.88-1) illustrates this. No other studies have been prepared by these agencies for the town of Littleton to date.

Errol Site (NH)

As illustrated in the flood hazard boundary map (ER Figure 301.88-2), prepared by FIA, the eastern portion of the site lies in a floodplain. However, structures, t ransmission lines or portions thereof associated with this candidate site would in all likelihood not be placed within this potential floodplain zone. No other stud ies have been prepared by these agencies for the town of Errol to date.

Comerford Site ( Nil)

The Comerford site does not lie in a designated floodplain area. A flood hazard boundary map prepared by FI A (ER Fi};ure 301.88-3) illustrates this. No other studies have been prepared by these agencies for the town of Monroe to date.

Bear Swamp Site (ItA)

The Bear Swamp site does not lie in a designated floodplain area. A flood hazard boundary map prepared by FI A (ER Figure 301.88-4) illustrates this. No other studies have been prepared by these agencies for the town of Rowe to date.

Gill /Ervine Site (f!A)

As illustrated on the flood hazard boundary map (ER Figure 301.88-5), prepared by FIA, portions of the Gill /Erving site lie in a designated floodplain area. Iloweve r , the structures, transnission lines and portions thereof would most probably not be placed in these zones.

301.88-1

Rome Point Site (RI)

As Illustrated in the flood hazard boundary map (ER Figure 301.88-6), prepared by FIA, the northern and eastern portions of the site lie in a floodplain. The Flood Insurance Study prepared by the Army, for FIA, in 1971 estimates the 100-year and standard project hurricane (SPil) elevations to be 11.2 feet and 14.2 f eet mean sea level, respectively. Flood i n);

of this site would be that associated with extreme tides caused by hurricanes and other large coastal storms.

Westerly Site (RI)

The Westerly site does not lie in a desir;nated floodplain area. A flood hazard boundary map prepared by FI A (ER Figure 301.88-7) illustrates this.

301.89 For each candidate site, please identif y and quantif y the major land-use clasa lfications (e.g., residential, agricultural, recreational, etc.). Please approximate the proportions of these land-uses that will be disturbed as a result of construction of the plant.

RESPONSE: Applicant has not perf ormed detailed engineering layout studies for the candidate alternate sites. In response to this request, Applicant used its best judgment in locating the center point of a two-unit nuclear generating station and the generalized construction / plant layout. A 270-acre parcel was used to represent the area impacted by operation and construction of the plant, consistent with the acreage at the proposed site.

Bear Swamp Site (MA)

The Bear Swamp habitat is primarily that of mature forests of mixed hardwoods and sof twoods indigenous to the region.

Of the total 515 acres of site area, approximately 5% (25 acres) occurs as abandoned f armland in an early secondary successional stage. Associated with this is a single leased dwelling.

A power facility cons' icted on this site would ut ilize about 48% (245 acres) of tt .orest habitat and all 25 acres of the abandoned farmland.

Gill /Erving Site (MA)

The Gill /Erving sites' habitat is that of mature forest with agriculture being the major land use being employed. To date, an estimated 75% (517 acres) of the combined 689 acres fo r the two sites exists as forest and 25% (172 acres) is being used for some type of agriculture. Should a power f acility be placed on the Erving site, an estimated 83% (230 acres) of forest habitat and 67% (40 acres) of agricultural land would be utilized. No residential areas exist on site.

The Errol site is predominately 1200 acres of a spruce fir forest with no other significant land-use classifications being found. Wetlands do exist adjacent to and to a limited 301.89-1

degree along a small stream entering the site.

An estimated 23% (270 acres) of the spruce fir forest would be disturbed should a power f acility be built on this site.

One seasonal dwelling is known to occu r on site.

ftooro Site (MI)

The Moore site exists primarily in a n~ ural state as a hardwood-white pine and hemlock forest e site has a number of boat ramps that were constructed by New England Power Company as part of the Moore liydroelectric Dam project and in association with the Moore Reservoir. Only small areas of the site, approximately 1% (5 acres) of the 460 acre total, are developed as farmlands.

The operation and construction of a power f acility situated on the Moore site would disturb approxinately 59% (270 acres) of the forest habitat and would not inf lu ence the rest of the other land-use cha rac te ris t ic s .

Comerford Site (Nil)

The Come rf ord site is primarily composed of areas of forest, both hardwoods and softwoods, and open agricultural lands.

Approximately 87% (850 acres) of the 980 acre site is a mixed hardwood-softwood community while the re ma ini ng 130 acres (13%) exists as agricultural lands. No dwellings exist on site.

Should a power f acility be placed on the Comerf ord site, an estimated 77% (100 acres) of agricultural land and 20% (170 acres) of f orested habitat would be altered.

Rome Point Site (RI)

The habitat of the Rome Point site is that of undeveloned forest and early successional fields and forest. Developed land use is at a minimum with only a f ew abandoned and seasonal dwellings owned by the Narragansett Electric Company now being found. Should plans be formulated to construct a powe r facility on site, the entire 240 acres would be utilized.

Wester 1v Site (RI)

The Westerly site is predominately a f orest habitat with a minimal amount of residential and recreational areas. Of the 400& acres of land owned by New England Power Company, 2% (8 acres) is a drive-in theater and 1% (5 acres) is rented residential land. The remaining 97% (387 acres) is either forest, forested wetlands or early successional fields.

301.89-2

Construction of a power facility would utilize about 68% (270 acres) of the 400 acres total. liabitats utilized for this would be a mixture of early successional fields, forest and forested marsh land.

Please approximate the proportions of these habitats that will be disturbed as a recult of construction of the plant.

RESPONSE: The response to RAI 301.89 discusses Applicant's method of analyzing potentially disturbed areas.

Bear Swamp Site (MA)

The habitat of the site is primarily hardwood and mixed hardwood-sof twood forest with a small area in the central portion being abandoned agricultural lands. Predominate species of the area are beech, maples, hemlocks and spruce, ranging f rom mature stands of the hardwoods and henlocks, some 21-60 ft. high to areas of younger softwoods mixed with older hardwoods.

A power f acility would utilize approximately 2 70 acres, of which 245 would be mixed a hardwoods-hemlock f ores t located in the north central region of the site adjacent to the Bear Swamp Upper Reservoir. In addition, all of the 25 acres of the abandoned f armland found in the central area would aise be utilized.

Gillh;rvinn Site (EQ Habitats of the Gill and Erving acreage are sinilar in species and seral stage. Each area is made up of primarily a forest habitat of mixed hardwoods and sof twoods. These occur in dense stande in which trees range from 41-60 feet in height.

Agricultural land (approximately 25% of the total 689 acres),

occurs along the Connecticut River in the eas tern half of the Gill acreage and is found mixed with some forested areas in the northern half of the Erving acreage.

Should a power facility '2 built on the Erving site, approximately 837. (230 acres) of the ruture stands of the mixed hardwoods and softwoods would be utilized. In addition, about 6,, (40 acres) of the agriculatural land would also be utilized.

Errol S it e_(NH)

The site habitat is primarily 1200 acres of mature s tand s of softwoods of medium-high density. The dominan; species complex is spruce and fir at po le s ta ge , having a diameter at breast height of 5-10 inches. A number of species of northern hardwoods (maples, oak) are f:ound in limited numbers with these. We tla nd s , which surround the site along the 301.90-1

northern and western boundaries, encroach upon the site along a small stream in the southwestern sector. This totals about 50-100 acres.

A power f acility placed in the north central portions of the site would disturb approximately 270 acres of the spruce-fir forest, leaving the wetlands fur ther south undia turbed .

Moore Site (tal)

The site habitat is primarily 455 acres of a mixed hardwood-softwood forest of mature trees in stands of medium density.

Although the site is principally forest, there are some areas of earlier successional species. Common forest s pe c ies are northern hardwoods, white pine, hemlock and spruce-fir at pole stage, having a diameter at breast h ei gh t of 5-10 inches.

A small portion of the site, an estimated 5 acrec, exists as pastureland or croplands, this being f ound at the site's southwest corner.

Locating a power facility in the north-central portion of the site would disturb about 270 acres of the mixed hardwood-softwood forest and not influence other habitat types to any substantial degree.

Conerford Site (?!H )

The site is principally that of a hardwood-softwood forest with approximately 130 acres of the 930 acres being used tor agriculture primarily in the southwestern areas. The dominent forest types are a northern hardwood community located in the western areas, white pine and hemlock stands in the southern and central portions and a spruce-fir community in the northeastern sectors. These exist as ma ture s tand s at medium to high densities with a diameter at breast height of 5-10 inches.

A power f acility on this site would be located on 270 acres in the northern and central areas. I t wou ld disturb approximately 100 acres of agricultural land and 170 acres of white pine-henlock fores t.

Rome Point Site (RI)

The Rome Point site is approximately 240 acres of hardwood forest, hardwocd-sof twood fields and hardwood-sof twood wetlands. The site's vege tation ir diverse in seral ,tage and species. Species range from mid to late successional forms with earlier successional species being found in a number of abandoned fleids and sandy areas. Approximate porpo rtions of these major forms are: hardwood forest 144 acres, mid-successional hardwoods-softwoods 50 acres, early successional 301.90-2

fields 25 acres, and marsh lands about 21 acres. Should a power f acility be constructed here, the entire 240 acre site would be used.

k'es t e rl y S i t e _{R _I )

The k'esterly site is primarily a forest habitat with abandoned fields and wetland areas also being represented. Hardwood species, predominately oak (Que rcus spp. ), dominate an estimated 350 acres (87%) of the site. O f this, about 75 acres has understory species similar to those of marshes and wetlands. Abandoned fields in an early se:a1 stage are also found along the west and northeas t boundar tes , and make up about 35 acres (10%) of the site area. Developed areas make up the remaining 13 acres (3%).

Construction of a power f acility would utilize approximately 235 acres of forested la nd , 50 acres of this being the forested marsh or wetlands. The 35 acres of abandoned field will also be taken.

301.91 Indicate those portions of proposed transnission lines associated with each candidate site that will cross t;ational Forests, Parks, and Monuments, and state and local jurisdiction of forests and parks based on readily available reconnaissance-level in f o rma t io n.

RESPONSE: The requested info rma tion is provided in Table 301.91-1.

Applicant considers the conversion of existing structures f rom carrying circuits of lesser voltages to 345 kV circuits wherein no relocation of existing structures and no wide.ing of rights-of-way is required as being of short-term impact (during the construction phase only). , cordingly, respo ses to RAIs 301.91 and 301.92 have treated any conversions without relocation of structures and widening of the rights-of-way separately from construction involving either the placement of structures or the widenitig of rights-of-way. As an example, the removal of steel lattice towers and setting of Il-frame pole type structures for the Millbury to West Fa r num L i ne ,

common to the Charlestown, Rome Point and Westerly sites, with no widening required, has been treated as new construction. Another example of construction would be the 10 foot widening of the Davis liridge - Millbury right-of-way from Bear Swamp Junction, Rowe, Massachusetts to Adams Road, Greenfield, Ma s sac h u s e t t s , although the only construction ac t ivi ty would be the replacement of an existin;; 230 kV circuit with a portion of the proposed Bear Swamp to Pratts Junction 345 kV circuit on the existing structures. As an example of a conversion, another portion of the proposed Bear Swamp to Pratts Junction circuit, from the above Adans Road to Pratts Junction would replace an existing 230 kV line on its existing structures without relocation and without any widening of the right-of-way. As a conversion, no impacts have been included in Applicant's response to RAIs 301.91. Fo r 301.92, it has been set up as a separate category. In a similar vein, percentages of forests or parks traversed have been calculated based upon miles of construction exclusive of conversionis.

?;o widening of existing rights-of-way or new rigt r; of-way are associated with the forests or parks listed below relative to the Rome Point, Gill /Erving or Bear Swamp sites.

Due to the complexity of the proposed transnission circuits for the liear Swamp candidate alternate site, an analysis is provided in Table 301.91-2.
