GENERAL

SECTION 1.10 - ENVIRONMENTAL COMPLIANCE

In Article 1.10.03-Water Pollution Control:

BEST MANAGEMENT PRACTICES

Add the following after Required Best Management Practice Number 13:

14. The Contractor is hereby notified that the State listed species of Special Concern

eastern box turtle (Terrapene carolina carolina), is present within the Project limits.

In Connecticut, this terrestrial turtle lives in a variety of habitats, including

woodlands, field edges, thickets, marshes, bogs, and stream banks. Typically

however, eastern box turtles are found in well-drained forest bottomlands and open

deciduous forests. They will use wetland areas at various times during the season.

During the hottest part of a summer day, they will wander to find springs and

seepages where they can burrow into the moist soil. Eastern box turtles overwinter

in upland forest, typically covered by leaf litter or woody debris. As temperatures

drop, the turtles burrow down into soft ground.

All construction activities taking place within the Project limits will need to be

coordinated with the Office of Environmental Planning (OEP) through the

Engineer. At least 10 days prior to the commencement of any construction

activities, the Contractor shall, through the Engineer, arrange for a CT DOT

Environmental Inspector from the OEP or their authorized delegate to meet and

discuss proper protocol for maintaining environmental commitments made for the

protection of this species and habitat. OEP will provide oversight through the

Engineer to ensure that the following protocols are followed and maintained during

the course of the Project.

For any work done during the eastern box turtle’s active period (April 1 to

October 31) the Department will require the following precautionary measures to

protect the eastern box turtle and eastern box turtle habitat:

a. All areas within the Project limits must be surveyed and cleared of any turtles

immediately prior to the commencement of initial clearing and grubbing

activities.

b. All construction personnel working within eastern box turtle habitat must be

apprised of the species description and the possible presence of this listed

species.

c. Exclusionary practices will be required in order to prevent any eastern box turtle

access to construction areas. These measures will need to be installed at the

limits of disturbance as shown on the plans.

170-3192 20 ADDENDUM NO. 1

Rev. Date 3-23-2018

GENERAL

d. Exclusionary fencing shall be at least 20” tall and must be secured to and

remain in contact with the ground. It shall be regularly inspected / maintained to

prevent any gaps or openings at ground level. Standard silt fence is adequate;

fencing with netting shall not be used.

e. The Contractor must search the work area each morning for the presence of this

listed species prior to any work being done.

f. Any eastern box turtles encountered within the immediate work area shall be

carefully moved to an adjacent area outside of the excluded area and the

Engineer shall be immediately informed in order to contact OEP with the

location.

g. All staging and storage areas in the vicinity of turtle habitat, outside of

previously paved locations, regardless of the duration of time they will be

utilized, must be reviewed by and receive written approval from OEP through

the Engineer.

h. No heavy machinery or vehicles may be parked in any unapproved eastern box

turtle habitat.

i. Exclusionary fencing shall be removed when it is no longer needed, and silt

fence shall be removed as soon as the area is stable to allow for reptile and

amphibian passage to resume.

Work may take place during the eastern box turtle’s inactive (hibernation) period

(November 1 to March 31) with the following additional precautionary measure:

a. Exclusionary fencing must be installed and the area inspected for turtles by the

Engineer or Engineer’s approved representative prior to October 1.

These practices will be applied to the entire Project unless a sketch is attached,

which identifies specific areas of concern.

This species is protected by State laws, which prohibit killing, harming, taking, or

keeping them in your possession. Photographs and the laws protecting eastern box

turtles shall be posted in the Contractor’s and DOT field offices (species ID sheets

will be provided by OEP).

15. The Contractor is hereby notified that one or more State listed species of bat, has

been documented within the project limits. In Connecticut, the Eastern small-footed

bat (Myotis leibii), tri-colored bat (Perimyotis subflavus), little brown bat

(Myotis lucifugus), Northern long-eared bat (Myotis septentrionalis) and the

Indiana bat (Myotis sodalis) are listed as endangered while the silver-haired bat

(Lasionycteris noctivagans) hoary bat (Lasiurus cinereus) and the red bat (Lasiurus

170-3192 21 ADDENDUM NO. 1

Rev. Date 3-23-2018

GENERAL

borealis) are listed as special concern. The Northern long eared and the Indiana

bats are also federally listed species. Bats are the only mammals capable of actual

flight and are primarily nocturnal. During the daylight bats roost in trees and caves,

but many have now adapted to roost in buildings including barns, houses, tunnels

and bridges. Within the project limits bats will use the snags, cavities and

underside of flakey bark to roost and raise young. Young bats are incapable of

flight for their first four to five weeks; therefore this project will have a Time of

Year (TOY) restriction for tree clearing to protect the young.

The Contractor shall through the Engineer at least 10 days prior to the

commencement of any construction activities, arrange for a CT DOT

Environmental Scientist from the Office of Environmental Planning (OEP) or their

authorized delegate to be available to meet and discuss proper protocol for

maintaining environmental commitments made to the protection of these species

and their habitat. OEP will provide oversight through the District to ensure that the

following protocols are followed and maintained during the course of the Project:

a. Clearing of any tree 3” DBH or greater will be prohibited between the time of

May 15th and August 15th. This TOY protects the pregnant female and her

young after birth. The actual birth is variable year to year; therefore this TOY

will provide the greatest amount of protection for all State listed bat species.

b. OEP will require that a pre-tree clearing walk through of the site be conducted so

all trees to be removed can be reviewed.

All listed bat species are protected by state laws which prohibit killing, harming,

taking, or keeping them in your possession. Any observations of a bat species are to

be reported to OEP at (860) 594-2937 or (860) 594-2938.

16. The Contractor is hereby notified that the final placement and stabilization of all

surplus excavated material at designated disposal sites within the railroad right-of-

way shall be the responsibility of the Railroad.

Construction Methods: 1. IVRP: Prior to any ground disturbance within the Project limits, the Contractor shall submit

an IVRP to the Engineer for review and approval. Within 30 days of receipt of the submittal, the

Engineer will notify the Contractor whether the IVRP is approved, rejected or requires

modifications by the Contractor. If any part of the plan is not approved, the Contractor shall

promptly make any necessary changes and re-submit the entire plan for approval. The entire plan

must be approved in writing prior to beginning any work on Site. In all cases, mechanical means

shall be considered before the use of herbicides. If mechanical means is neither feasible nor

recommended, an explanation must be provided in the IVRP. All removal methods shall prevent

the spread of seeds – no mowing or “Brush Hog” equipment will be allowed. The approved

methods must be capable of total removal and eradication of all identified invasive species in the

designated areas throughout the Contract and the 1-Year Plant Establishment Period.

The IVRP shall include a schedule and outline with the following information:

1) The Contractor’s methods of determining invasive vegetation surveyed limits, including:

a. Stake out the limits prior to the initial treatment

b. Maintain a record of the staked limits throughout the life of the Contract

2) Identification of the type(s) of invasive species present within the field surveyed limits

170-3192 29 ADDENDUM NO. 1

Rev. 6/16/2017

ITEM #0952051A

3) A marked up plan sheet outlining the invasive species limits and identifying the types of

invasive species present within those limits and total square yards of proposed removal

4) For each species present on-Site, the following shall be described:

a. Methods to eradicate specific invasive plant species for the life of the Contract (e.g.

mechanical, herbicide, etc.) shall include any initial, intermediate and 1-Year Plant

Establishment Period Treatment eradication methods for each plant species

b. Types and concentrations of any herbicides to be used, including any adjuvants,

SDS sheets, types of tools or machinery to be used

c. Schedules showing dates and eradication methods for the initial, intermediate, and

1-Year Plant Establishment Period Treatments. This schedule must take into

consideration stage construction, the time period required between herbicide

application, and the physical removal of the target species wherever such

methodology is employed

5) All invasive species are considered controlled materials and are to be taken off-Site to an

approved disposal facility. For disposal methods:

a. Provide address of location, current permits / letters from the town authorizing such

activity and a Site map (complete with regulated areas)

b. Wood chips from invasive species are not allowed to be stockpiled or reused on-

Site

c. Wood chipping on-Site will be allowed if temporarily stored in a properly

contained enclosure and removed at the end of the treatment cycle

d. Invasive plants shall not be buried on-Site

6) Proof of CT DEEP licensure for herbicide application

7) A description of safety equipment required

8) Procedures for handling chemical spills

Where certain species of invasive vegetation are present and identified on the plan sheets,

permits, or as identified in the field by the Engineer, the removal via bulk mechanical excavation

of such vegetation and the underlying soils may be required as directed. The approved method

must be capable of the removal of all soil to a depth where invasive plant material and root system

is no longer evident, or as directed by the Engineer.

Whether the Contractor’s method of removal is by mechanical excavation or cutting and spraying

of herbicides, invasive species must be removed separately from clearing and grubbing operations

and disposed at an approved location as described in the Contractor’s IVRP.

No equipment or vehicles other than that required to complete the work will be permitted in the

areas designated for invasive vegetation removal. Any equipment used to process invasive

vegetation, such as chippers and transport vehicles, must be cleaned prior to further use.

Any invasive species control and removal work performed throughout the duration of the

Contract that causes damage or soil disturbance shall be repaired at the Contractor’s expense

within 7 days. It is the Contractor’s responsibility to identify additional areas of concern for

invasive vegetation within the limits of the Project, notify the Engineer, and to amend the IVRP.

Rev. 6/16/2017

ITEM #0952051A

The Contractor shall be responsible to identify invasive vegetation at all times of the year and to

prepare a plan for its eradication without assistance.

All treatments, with the exception of an initial mechanical excavation of invasive species, will

not be allowed outside of the optimal growing season between the dates of October 1 and May 31.

Herbicide applications will not be permitted during any rain event or during windy conditions.

Broadcast or uncontrolled spray application will not be permitted and care must be taken to

avoid contacting non-target native species. If any non-target native species to remain within the

Project limits are inadvertently treated with herbicide and perish, the Contractor will be

responsible to replace in-kind species at no cost to the State.

Remove all twining vines in treetops to the greatest extent possible without damaging the

branches of the supporting desired vegetation. Cut and remove vines overtopping tree canopies

to the extent practical. Climbing spikes will not be permitted for aerial work.

The Contractor shall also:

1) Maintain the labels for herbicides being used in his/her possession

2) Conduct all herbicide formulations and applications, including the addition of appropriate

surfactants and other adjuvants, in strict conformance with the manufacturer's

recommendation and per requirements of regulatory agencies

3) Maintain a written record of herbicide application, including the formulation,

concentration, area treated, and date for each application. The records are to be provided

by the commercial applicator and submitted to the Engineer following each treatment

Flush cut brush and trees shall not be more than 2 inches above the ground line. Prune out any

branches on non-treatment plants that are damaged during removal of vegetation. All corrective

pruning shall conform to the National Arborists Association Pruning Standards.

Wherever removal operations result in exposed soils, disturbed areas shall be vegetatively

stabilized with the appropriate seed mix and protected with hay, cellulous fiber mulch, or erosion

control matting.

Once the IVRP is approved, a field review shall be scheduled for the Contractor and Engineer to

review the limits of invasive species removal (surveyed and flagged by the Contactor prior to the

meeting), the specific species required to be removed, and the Contractor’s submitted invasive

species removal plan. At this time, the Engineer may identify additional invasive species or

designate additional areas for removal that are not included with the Contractor’s submitted

IVRP.

If changes are required to the approved IVRP during the life of the Contract, these changes

shall be documented by the Contractor and resubmitted to the Engineer for review and approval

a minimum of 10 days prior to beginning of the additional work associated with the change. The

Contractor shall provide a 10 day work notice to the Engineer prior to proceeding with each

treatment.

2. Treatments: The treatment schedule below may be modified based on field conditions at the

discretion of the Engineer. The Contractor shall provide a 10 day work notice to the Engineer

prior to proceeding with each treatment. In all cases, each treatment must be reviewed once the

work is performed, and accepted before payment is made for that treatment stage.

Initial Treatment: Shall commence at the beginning of the Contract time, prior to clearing and

grubbing activities. Any invasive species found within a proposed cut slope shall be fully

eradicated to the satisfaction of the Engineer prior to any earth work operations. After the

completion of the initial treatment, the work must be reviewed and accepted by the Engineer

prior to any earth excavation in that area. If herbicide is the initial treatment method, a minimum

of 14 days is required prior to clearing and grubbing operations, so the herbicide application can

take effect.

Intermediate Treatment(s): Shall be conducted during the optimal growing season between the

dates of June 1 and September 30 for invasive species up to and including 10 days prior to plant

installation or at the end of the Project if no landscaping plan is in the Contract. Optimal

treatment times may be specific to the species being treated and this must be considered and

documented when developing the Invasive Vegetation Removal Plan. Several treatments may be

required to treat all species that are present.

1-Year Plant Establishment Period Treatment: Treatments as needed or as directed by the

Engineer shall be conducted throughout the 1-Year Plant Establishment Period or when required

under another Contract item.

Method of Measurement: This work will be measured for payment by the number of square

yards of invasive vegetation identified, surveyed, treated and eradicated as required including any

required re-treatment of any regrowth or new growth. No additional payment will be made for

subsequent treatments. The area for removal will be surveyed and flagged prior to treatment and

measured. After a review of the surveyed limits, the Engineer may designate additional areas for

removal that are not shown on the plans. These additional areas will be measured for payment and

included as part of the Contract work.

Where selective removal is required, the square yards of the drip line of the invasive vegetation

will be measured for payment.

Basis of Payment: This work will be paid for at the Contract unit price per square yard for

"Control and Removal of Invasive Vegetation.” This payment shall include all labor, surveys,

materials, tools, and equipment necessary for limits of the invasive area(s); maintenance of the

limits throughout the Project; species identification; and cutting, excavation, treating, re-treating,

removal, and off-Site disposal of designated invasive plant material. Off-Site disposal of residue

shall include the loading, transport, dumping, and fees associated with legal off-site disposal.

Upon approval of the required IVRP, the Contractor will receive a payment equal to 10%

of the estimated Contract value

Rev. 6/16/2017

ITEM #0952051A

Upon initial herbicide or mechanical removal treatment methods as it is described in the

IVRP, the Contractor will receive a payment equal to 20% of all areas receiving treatment

Upon successful completion of the initial treatment period, as determined during the review

by the Engineer, the Contractor will receive a payment equal to 20%

Upon successful completion of the intermediate treatment period as determined during the

Site review by the Engineer, the Contractor will receive a payment equal to 20%

Upon successful completion of the 1-Year Plant Establishment Period covering all treated

areas on the Project (or the last treatment for those Projects which may not include a 1-Year

Plant Establishment Period), the Contractor will receive final payment equal to the

measured areas in place and treated, less any previous payments

Where bulk excavation is required for removal, this work shall be covered under the Contract

Item “Earth Excavation” for all excavation in excess of 2 feet. All other vegetation not designated

as invasive vegetation shall be removed in compliance with the Item “Clearing and Grubbing” in

accordance with Section 2.01.

Vegetative stabilization of disturbed areas will be paid for under the respective Contract Items:

“Turf Establishment,” “Wetland Grass Establishment,” or “Conservation Seeding for Slopes.”
