b Wetland classification according to Cowardin et al. 1979: PEM = Palustrine Emergent Wetland; PSS = Palustrine Scrub-Shrub Wetland; PFO 

Wetland. 

c 0.0 = wetland is not crossed by the pipeline but is in workspace. d Construction Acreage = all workspace during construction activities (temporary plus permanent); Operation Acreage = 10-foot-wide corridor pe

herbaceous vegetated cover through PSS wetlands, and 30-foot-wide corridor permanently maintained through PFO wetlands where trees tal

selectively cut and removed. The permanently maintained corridors represent a change in cover type from PFO to PSS and PEM or PSS to Poperation impact on PEM wetlands, since there would be no change in the pre- and post-construction vegetation cover type. Construction imp

construction wetland vegetation cover type for each wetland included in the table. The right-of-way width at all wetland crossings is 75 feet, ex

described in Table 2.3-8. 

e Pennsylvania classifies wetlands as exceptional value or other per 25 Pa. Code Ch. 105. f Crossing Methods for wetlands are described in Section 2.3.5; I = Standard Crossing; II = Conventional Crossing; III = Push/Pull Crossing; IV 

Horizontal Directional Drill; N/A = Wetland not crossed by pipeline

____________________ N/A = Not Applicable – for wetland class with N/A it indicates that the wetland is not classified by the NYSDEC. a Crossings and impacts for wetland features with “XX” in identification name taken from NWI GIS datalayer. No wetlands were identified in the We

during field surveys in 2012, including the pig receiver area. Wetlands associated with MLVs are included in the corresponding pipeline segment

b Wetland classification according to Cowardin et al. 1979: PEM = Palustrine Emergent Wetland; PSS = Palustrine Scrub-Shrub Wetland; PFO = Pc 0.0 ft Crossing Length = wetland is not crossed by the pipeline but is within the workspace. d Construction Acreage = all workspace during construction activities (temporary plus permanent); Operation Acreage = 10-foot-wide corridor perm

herbaceous vegetated cover through PSS wetlands, and 30-foot-wide corridor permanently maintained through PFO wetlands where trees taller t

cut and removed. The permanently maintained corridors represent a change in cover type from PFO to PSS and PEM or PSS to PEM; there wou

PEM wetlands, since there would be no change in the pre- and post-construction vegetation cover type. Construction impacts were calculated us

footprint surface area and existing land use based on field surveys or desktop analysis, including NWI data, in those areas where permission has field surveys. Surface area of operational maintenance corridor as described above were used to calculate acres of operation impact on each pre

vegetation cover type for each wetland included in the table. The right-of-way width at all wetland crossings is 75 feet, except for those wetlands 

e New York classifies wetlands as Class I, II, III, IV (6 NYCRR Chapter X Part 664). Classification descriptions are provided above in Section 2.3.1f Crossing Methods for wetlands are described in Section 2.3.5; I = Standard Crossing; II = Conventional Crossing; III = Push/Pull Crossing; IV = C

Horizontal Directional Drill; N/A = Wetland not crossed by pipeline
