B. In the comparison of Bids, alternates will be applied in the same order of priority as listed in the Bid Form. To determine the Bid prices for purposes of comparison, Owner will announce to all bidders a “Base Bid plus alternates” budget after receiving all Bids, but prior to opening them. For comparison purposes alternates will be accepted, following the order of priority established in the Bid Form, until doing so would cause the budget to be exceeded. After determination of the Successful Bidder based on this comparative process and on the responsiveness, responsibility, and other factors set forth in these Instructions, the award may be made to said Successful Bidder on its base Bid and any combination of its additive alternate Bids for which Owner determines funds will be available at the time of award.

C. For the determination of the apparent low Bidder when unit price bids are submitted, Bids will be compared on the basis of the total of the products of the estimated quantity of each item and unit price Bid for that item, together with any lump sum items.

18.06 In evaluating whether a Bidder is responsible, Owner will consider the qualifications of the Bidder and may consider the qualifications and experience of Subcontractors and Suppliers proposed for those portions of the Work for which the identity of Subcontractors and Suppliers must be submitted as provided in the Bidding Documents.

18.07 Owner may conduct such investigations as Owner deems necessary to establish the responsibility, qualifications, and financial ability of Bidders and any proposed Subcontractors or Suppliers.

18.08 Before award is made to a Bidder not a resident of the State in which the Project is located, such Bidder shall be properly licensed and authorized to do business in Connecticut and shall designate in said State a person on whom service of process can be made in the event of litigation.

ARTICLE 19—BONDS AND INSURANCE

19.01 Article 6 of the General Conditions, as may be modified by the Supplementary Conditions, sets forth Owner’s requirements as to performance and payment bonds, other required bonds (if any), and insurance.

Subject: Tershen Mill Brownfield Remediation Filing # 133388 NDDB – New Determination Number: 202506948 459 Church St Amston

Expiration Date: 9/23/2027

Current data maintained by the Natural Diversity Database (NDDB) and housed in the DEEP ezFile portal indicates that populations of the following State Endangered, Threatened, or Special Concern species (RCA Sec. 26-306) have been documented within the project area or in close proximity to the proposed Remediation/Contaminated soil remediation, Tershen Mill Brownfield Remediation.

Brook floater (Alasmidonta varicosa) Eastern pearlshell (Margaritifera margaritifera) Eastern hognose snake (Heterodon platirhinos) Spotted turtle (Clemmys guttata) Wood turtle (Glyptemys insculpta)

In accordance with the project information provided in your request submittal, implementation of the following Best Management Practices will avoid negative impacts to listed species:

Common Name Brook floater Scientific Name Alasmidonta varicosa Taxa invertebrate Status1 E General Ecology Habitat: Small to medium-sized rivers, usually in gravel and cobble substrates in swift current.

Host fish include longnose dace (Rhinichthys cataractae), blacknose dace (Rhinichthys atratulus), slimy sculpin (Cottus cognatus), golden shiner (Notemigonus crysoleucas), pumpkinseed sunfish (Lepomis gibbosus), yellow perch (Perca flavescens), and tessellated darter (Etheostoma olmstedi). The brook floater is critically imperiled throughout most of New England, including Connecticut. Remaining populations of brook floaters are found in undisturbed sections of streams in the upper reaches of watersheds that have relatively in-tact upland forest. DEEP Wildlife Division considers all streams with populations of brook floaters to be conservation priorities. Protected riparian buffers should be increased from the standard

100ft to 300ft of streams within 1km upriver of brook floater habitat. Percent forest cover throughout the watershed as well as adjacent to the rivers and streams has been highly correlated with Brook floater persistence, and this buffer will help maintain local habitat characteristics for this sensitive species.

Best Management Practice We do not anticipate significant negative impacts to this species from your Project

Type category selected in this location. Impact from this project can be minimized if you follow any applicable Best Practices and monitoring associated with your project activities and/or permit requirements, minimize impact to and loss of preferred habitat, and include any protection measures included here in the Species General Ecology that relate to your project activities before, during, and after completion.

Common Name Eastern pearlshell Scientific Name Margaritifera margaritifera Taxa invertebrate Status1 SC General Ecology This freshwater mussel species lives buried in clean, stable, mixed substrate in fast-flowing unpolluted streams and rivers. Its host fish include Atlantic salmon (Salmo salar), brook trout (Salvelinus fontinalis), brown trout (Salmo trutta), rainbow trout (Onchorhynchus mykiss). Best habitats are good trout streams that are heavily shaded by a riparian canopy, possess clean cold water with high dissolved oxygen, and have stable channels with substrates of coarse sand, gravel, and cobble. Factors that limit the eastern pearlshell are changes to water quality, including eutrophication, acidification, sedimentation, and increases in water temperature.

Best Management Practice We do not anticipate significant negative impacts to this species from your Project

Type category selected in this location.

Common Name Eastern hognose snake Scientific Name Heterodon platirhinos Taxa reptile Status1 SC General Ecology In Connecticut, these snakes are found in well-drained forest bottomlands and a matrix of open deciduous forests and early successional habitat, including powerlines. Within the early successional habitat, they preferentially use habitat that consists of sandy soils with medium to high vegetation cover and coarse woody debris. They tend to avoid dense forest, wetlands and developed areas. Paved roads may present a barrier to dispersal and connectivity within populations. Snakes are dormant between November 1 and April 1. They will overwinter in a variety of habitats, preferably at the edges of forest and within open habitats if available. They have been observed to overwinter under areas of tree roots, rodent burrows, rock crevices, or excavate their own dens in sandy soils. Many of these harmless snakes are killed by people who are convinced that they are venomous and dangerous. When confronted, the hognose snake will suck in air, spread the skin around its head and neck like a cobra, hiss, and lunge as if to strike. Take the time to learn about, understand, and respect this reptile, and share your knowledge with others. Being able to identify and educate others about the eastern hog-nosed snake can help conserve this species. The more people that are aware of the physical and behavioral identification of this unique snake, the more individuals that can be spared from unnecessary killing. If you encounter a hog-nosed snake, observe it from a distance and allow it to go on its way. All snakes will retreat from humans if given a chance.

Best Management Practice Apply time of year restrictions as appropriate for the habitat types you will be conducting work.

• Construction that involves ground disturbance in suitable habitat described above should be done during the active season, which is April 1 through Oct. 31 to avoid killing hibernating animals.

• Construction that will be confined to managed turf grass , agricultural fields, 00 31 46-6

22 04/2026 impervious or graveled surfaces, or areas confined to compacted soil can be conducted at any time of year.

For work conducted during the active season (April 1- Oct 31):

• Construction workers should be apprised of the species description and possible presence and that any snakes encountered site should not be killed.

• The immediate work area should be scanned for reptiles before starting work using mechanical equipment

• Any reptiles found should be moved out of the way. These animals are protected by law and should never be taken off site.

• Work conducted during early morning and evening hours should occur with special care not to harm basking individuals.

• No vehicles or heavy machinery should be parked overnight in any sandy areas especially within early successional habitat or along forest edges.

• Areas where excavated or stockpiled materials are stored will be first…
