Downeast Reliability Project
Comprehensive Land Technologies, Inc. (CLT) began work on this Bangor Hydro project in February 2011 to
clear 12.6 miles of new powerline right-of-way in Washington County, Maine. This project involves specific
clearing methods and/or timing restrictions for wetlands, stream buffers, significant vernal pool habitat, and
rare plants. Other challenges presented by this project include problematic access and deep snow.

Maine Power Reliability Program
CLT began work on Central Maine Power's 350-mile, 5-year Maine Power Reliability Program project in August
2010. The project involves clearing new right-of-way and widening existing right-of-way across approximately
75 communities from Orrington to Eliot. Challenges include scheduling, resource timing restrictions, specific
clearing methods for sensitive habitats, invasive species zones, thousands of feet of contiguous wetland, and
poor access.

Central Maine Power Section 174 Rebuild
CLT worked with Coutts Bros. during the winter and spring of 2010 to upgrade four miles of 34.5kV
transmission line to 69kV in Saco and Biddeford, Maine. CLT cleared vegetation for this project located in close
proximity to homes and public roads, which required a substantial amount of hand-felling and landowner
coordination. CLT provided and installed timber construction mats to allow access across wetlands,
waterbodies, and golf courses. CLT also restored grade along sidehill sections, installed rolled erosion control
product, and applied temporary and permanent seed and mulch.

Central Maine Power Section 219/163 Rebuild
CLT cleared vegetation to widen an 18-mile-long electric transmission and natural gas pipeline right-of-way
located in Buxton, Saco, and Arundel, Maine. Area cleared consisted of steep ravines, wetlands, and
waterbodies adjacent to an energized 115kV powerline. From winter to fall 2008 CLT also provided and
installed timber construction mats for access during construction, and restored and stabilized disturbed areas
following new powerine construction.

Northeast Reliability Interconnect
CLT worked on this Bangor Hydro project during the winter of 2006, clearing vegetation to widen 12 miles of
existing right-of-way adjacent to a 24-inch pressurized natural gas pipeline and an energized 345kV
transmission line. The project involved clearing approximately 100 acres of wetland, 9 stream crossings, and
60 different landowners.

Wind Power

Kibby Wind Power Project
From 2008 to 2010, CLT was involved with the 132MW Kibby Wind Power Project located in Kibby and Skinner
Townships, Maine. Services provided by CLT to Reed & Reed, Sargent Corporation, 3 Phase Line Construction,
TransCanada, and Genivar for the wind farm included 225 acres of ridgetop and collector line clearing; 175
acres of grubbing and stump grinding; timber construction mat rental, installation and removal; erosion and
sediment control; and meteorological tower demolition and installation. This project required working in a
remote area with sub-zero temperatures, unstable soils, and steep, rocky terrain.

Stetson Wind and Stetson Wind II
During the winter of 2008 and fall of 2009 CLT worked with Sargent Corporation on the 57MW Stetson Wind
and 25.5MW Stetson Wind II wind power projects in Danforth, Maine. CLT prepared 150 acres by grubbing and
grinding stumps for the project crane paths and turbine pads.

Natural Gas Pipelines & Facilities

Maritimes & Northeast Pipeline/Spectra Energy Phase IV

Woodchopping Ridge Compressor Station
In 2008 CLT worked with Ranger Plant Construction, Maritimes & Northeast Pipeline, and Spectra Energy on
construction of this new 14-acre natural gas compressor station and suction/discharge right-of-way located in
rural Hancock County, Maine. CLT provided clearing, grubbing, and stump grinding; erosion and sediment
control, including erosion control mix berms, installation of rolled erosion control products, seed and mulch, and
hydroseeding; topsoil stripping, stockpile, screening, and replacement; site work, including blasting contract
management, rock crushing and screening, rough and finish grading, well and septic system installation, and
construction of 2500 feet of access road; installation of stormwater structures, including level spreaders,
armored and vegetated channels; restoration, including site clean-up and right-of-way reclamation.

Searsmont Compressor Station
From 2007 to 2009, CLT worked with Northern Construction, Maritimes & Northeast Pipeline, and Spectra
Energy during construction of this new 21-acre natural gas compressor station and suction/discharge
right-of-way in Searsmont, Maine. CLT cleared vegetation, grubbed and ground all stumps and woody debris,
installed erosion control mix berms, and installed under-drainage inside the compressor station. This project
involved working around sensitive resources, as well as a 24-inch pressurized natural gas pipeline and an
energized 345kV transmission line.

Eliot and Westbrook Compressor Stations
In summer 2007 and spring 2008, CLT worked with Northern Construction, Maritimes & Northeast Pipeline, and
Spectra Energy on construction of these two new natural gas compressor statsions located in Eliot and
Westbrook, Maine. CLT cleared vegetation, grubbed and ground all stumps and woody debris, and installed
erosion controls. These sites required working around sensitives resources, including wetlands, vernal pools,
and protected plant species. The projects also required working around 24-inch pressurized natural gas
pipelines and energized 345kV transmission lines.

Maritimes & Northeast Pipeline AC Mitigation Project
During the summer of 2007 CLT provided and installed timber construction mats for access across wetlands
and waterbodies along approximately 60 miles of exisiting pipeline right-of-way for this project located in rural
Penobscot, Hancock, and Washington Counties, Maine. This project required working directly adjacent to a
24-inch pressurized natural gas pipeline for the purpose of plowing-in zinc ribbon alongside the buried pipeline
(completed by Mears Group). CLT worked closely with Mears to coordinate project progress and ensure access
across more than 46,000 linear feet of wetland and 27 waterbody crossings, which resulted in finishing the
zinc ribbon installation ahead of schedule.
