Massive $315M electrical project to bring weeks of detours to CT community’s well-traveled route


 Kenneth R. Gosselin

An already congested thoroughfare — and well-traveled commuter route from suburbs to the west — is expected to worsen this summer as a major leg of $315 million underground electric transmission cable upgrade will lead to lane closures, partly shut down streets and lengthy detours.

The epicenter of the construction along Asylum Avenue in Hartford is at the intersection of Scarborough and Whitney streets in the West End with work tentatively beginning on May 4 and stretching between eight and 12 weeks, according to a project update provided to local property owners by Eversource Energy.

For years, traffic congestion on Asylum Avenue — stretching from Asylum Hill through the West End — has been a concern for the city, with proposals aired in recent years to ease congestion. The concern is so great that West End residents complained at a hearing on a neighborhood development proposal in late 2024 that they were forced to take longer, alternate routes just to avoid the near-constant gridlock.

Eversource, the state’s largest utility, won state approval to replace nearly 7 miles of aging, underground transmission lines in Hartford — installed in 1974 — with more advanced cables. The work along Asylum Avenue is a slice of a 3-year project, which didn’t need local approvals.

The cables “will enhance the safety and reliability of the electric system, increase its capacity to meet current and future energy demand in the Hartford area, and reduce the risk for fluid leaks or environmental hazards,” Tricia Modifica, an Eversource spokeswoman, said, in a statement.

The overall project in Hartford launched a year ago and construction is expected to be completed in mid-2027. The project involves replacing two transmission lines that are considered critical to the city’s power grid.

Modifica said the utility has been in touch with property owners and businesses since June 2023.

“As we continue to receive and review feedback from community members, businesses and city partners regarding construction phases and traffic impacts in the area, we are evaluating ways to safely expedite project work to help minimize impacts to the neighborhood and balance concerns,” Modifica said.

The city of Hartford is not involved with the project itself but did consult with Eversource on its plans for lane closures and detours.

Hartford Mayor Arunan Arulampalam said the timing was unfortunately heading into the summer when the city wants to attract more visitors to events.

“Certainly it makes it more difficult, but we don’t have control over the work being done,” Arulampalam said. “But we’re doing everything we can to try to minimize the impact.”

Some components of the project in and around Asylum Avenue are:

Intersection of Asylum and Scarborough and Whitney streets: Beginning May 4, the northbound lane of Scarborough will be closed. Construction will take place on the east side of the intersection, where Asylum Avenue will be fully closed. Traffic will still be able to travel north on Whitney Street and turn west onto Asylum. In addition, motorists also will be able to travel east on Asylum and turn south onto Whitney. Both, however, will require following detours.

The east side of the intersection and the northbound lane of Scarborough will remain closed 24/7 for the duration of the construction, about eight to 12 weeks.

Scarborough Street at Albany Avenue: As of Monday, the southbound lane of Scarborough Street will be closed 24/7 for up to 3 weeks. The excavation required for the work is such that roadway plates cannot be safely put in place overnight. All residents of Scarborough will have access to their homes.

Once this work is complete, the Scarborough’s southbound lane will reopen and work will begin on the northbound lane, about the same time as work begins at the Asylum street intersection.

The overall project includes replacing two transmission lines.

One, the 1722 line runs nearly three miles from the Northwest Hartford Substation on Albany Avenue to the Southwest Hartford Substation on New Park Avenue. The other, the 1704 Line, stretches about four miles from Southwest Hartford Substation to South Meadows Substation on Reserve Road.


$25M Naugatuck projects plan goes to voters with no tax hike, mayor says

Sloan Brewster

NAUGATUCK — Voters are being asked to approve a $25 million spending plan that officials say won’t raise taxes.

On April 28, the borough will hold a referendum on capital projects that includes designing a new regional animal control facility, building a new dispatch center at the police station and $10 million in roadwork.

How to pay for it all

Mayor N. Warren “Pete” Hess III said bonding for the projects will not impact the tax rate.

“This is probably, I mean to me, the best part of the story,” he said. “Basically, we’re making all of these improvements without impacting the mill rate.”

The way Naugatuck officials will accomplish this and still get the money and start the work right away is by reconstructing the debt so it won’t be due for six years, Hess said. By then, $5 or $6 million in revenue from an Amazon facility being constructed in town will start rolling in as that’s when tax incentives for the project run out.

That same year, the town will stop paying on old pension debt, saving it about $4 million.

“So in six years from today, the town is $10 million better off than we are today,” Hess said. “The benefit comes to us now without impacting the mill rate. Get everything done now, make our town better now and not affect the mill rate.”

Creating a regional facility

The town wants to replace the animal control building on Cherry Street Extension beside the wastewater treatment plant with a new facility on land behind the police station.

“Our current animal control facility is woefully inadequate and requires a complete replacement,” Hess said.

The first steps -- drafting a design, surveying the land, preparing a site plan and getting utilities to the site -- would be covered by $500,000 to be borrowed if the referendum passes. 

The borough is also working with the Naugatuck Valley Council of Governments to apply for a state grant to build the state-of-the-art facility, Hess added. The plan is for Prospect to join in the regional facility.

Officials are also hoping other towns will also hop on board.

The remote land behind the police station, which the town already owns, is large enough to accommodate a regional facility, the mayor said. The first-class facility would have up-to-date temperature control, which is now required by law.

The town has been talking about the project for about a year, Hess added.

If the state does not come through with a grant for the construction, the town will look into alternative funding.

“We want to get the state to pay as much as we can get, but we’re definitely going to be doing a new facility,” Hess said.

Improving cell coverage

The list also includes a $7.5 million public safety project to improve emergency service coverage, Hess said. The town will work with the state on a system that will eliminate dead zones and provide town-wide coverage.

“We have some spots in town with no cell coverage or emergency communication,” he said. Police, fire, emergency medical services “will all be able to communication with each other in emergencies.”

The plan includes building a new dispatch center in the police station and acquiring land for additional parking.

The biggest price tag: roads

The item with the highest price tag is $10 million for repairs, reconstruction and repaving of various roads in the borough. The list includes approximately 150 roads, encompassing every one in town that hasn’t been paved in the current paving plan and micro-paving some additional roads, Hess said. The plan is to complete the work over the next two years.

The end result? “Taking horrible roads, making them excellent,” he said.

What voters need to know

So what will residents actually have to decide on come the April 28 referendum?

The full list that will be before voters is:

$10 million in repairs, reconstruction and repaving of various borough roads;

$7.5 million for a public safety dispatch center radio tower and radios;

$1 million for land acquisition;

$560,000 for improvements to school buildings; 

$400,000 for Tuttle House renovations;

$200,000 for senior center renovations; 

$170,000 for designs for a pedestrian bridge;

$150,000 for Salem Park improvements;

$500,000 for Animal Control Facility design and site work;

$100,000 for Maple Street Bridge lighting repair;

$300,000 for a roundabout design for the Tuttle building;

$400,000 for a Department of Public Works storage building;

$800,000 for Hillside Avenue improvements;

$800,000 for Rubber Avenue corridor upgrades;

$550,000 for Hop Brook Park improvements;

$400,000 for upgrades to courts and parking lots at Baummer’s Park;

$420,000 for lighting for fields at City Hill and Maple Hill;

$500,000 for stormwater and infrastructure improvements;

and $250,000 for a feasibility study for Salem School.

The referendum will take place from 6 a.m. to 8 p.m. at the Naugatuck Park & Recreation, 607 Rubber Ave. 


Local Donation Powers UConn Construction Engineering Programs

Claire Galvin

Construction engineering students will be able to round out their theoretical education with hands-on heavy equipment experience, courtesy of a large donation by a local equipment retailer. 

Tyler Equipment Corporation will gift the UConn College of Engineering with a Volvo Electric L20 Wheel Loader for UConn’s construction engineering and management (CEM) program. 

“We are incredibly grateful to Tyler Equipment for this impactful donation,” said School of Civil and Environmental Engineering director Kay Wille. “We want our students to be educated on the latest industry trends and technologies. Through generous partners, we can ensure our students are ready to make positive contributions to the engineering and construction fields.”

The wheel loader will be used in an operator’s course offered to UConn’s CEM minor students. 

“As the construction industry continues to evolve toward more sustainable and technologically advanced solutions, it’s critical that students gain hands-on experience with the equipment shaping the future of the field,” says Tyler Equipment marketing coordinator Courtney Rush. “We’re excited to partner with UConn to help prepare the next wave of engineers and construction professionals.” 

Connecticut’s Local 478 Operator’s Union will aid in course construction, and provide a simulator. Students will become familiarized with machine operations as well as innovations in construction equipment, including electronic equipment and on-board intelligent systems. 

“As the construction industry continues to evolve with new technologies—such as automation, digital controls, and data-driven job site management—our training programs ensure that members stay ahead of the curve,” says Local 478 Director of Training and Fund Administrator Gregg Strede. “By combining proven instructional methods with innovative simulation tools, we prepare a highly skilled workforce capable of meeting the demands of modern construction.” 

There are approximately 40 students in the CEM program currently, and enrollment is continuously growing. 

According to Kay, through this donation, students will better understand how real machinery operators might work on construction sites. Students will learn about vehicle safety, and after being trained on the simulator, will learn how to drive and steer. 

The electric vehicle is a quiet, efficient, and sustainable option for construction sites. 

Currently, students can select the CEM minor. Engineering leadership are hopeful a new bachelor of science degree in construction engineering, management and intelligent systems (CEMI) will be approved and instated in the future. 

The major will emphasize fundamentals in construction engineering and construction management, combined with modern tools in data capturing, data analytics, and artificial intelligence. Advisory input and internships will keep coursework aligned with active practices in the state and national construction sector. 

“Nationwide, the industry must attract hundreds of thousands of additional workers in the next few years to meet increasing construction demand,” Wille said. “As a school, we can scale collaboration with contractors and owners; align coursework with real project requirements; and expand internships and senior design projects that integrate design, sustainability, and delivery constraints.” 

The degree will be designed to produce practice-ready graduates by emphasizing construction means and methods; project and safety management; structural analysis and design for construction, building, and infrastructure systems; as well as horizontal and vertical construction. 


Plainfield lawmakers resurrect proposal that would grant residents veto power over trash plant

Alison Cross

Plainfield — An upcoming meeting on the controversial plan to build a trash plant on Route 12 is expected to bring more community opposition.

SMART Technology Systems LLC will be presenting draft plans for the trash-to-energy facility on April 9 at 7 p.m. on Zoom via the link https://pullcom.zoom.us/s/83057839771. The virtual presentation will include a public comment period that will allow up to three minutes per speaker.

Thursday's meeting is the latest step in a long regulatory process for the proposed trash plant, which would accept 1,800 tons of municipal solid waste each day.

The plant would convert the waste into 45 megawatts of electric power and renewable natural gas through a multi-step process that includes material separation, gasification, power generation, anaerobic digestion and carbon capture.

SMART has published more than 1,500 pages of application materials for the trash plant, which SMART said would be the first of its kind in the United States. Here is a snapshot of what SMART has disclosed about the project and how changing federal regulations could impact emission standards.

Where is the trash plant located?

The SMART facility would be constructed on 81 acres within a larger 506-acre property near the intersection of Norwich Road and Black Hill Road. The land is currently zoned residential, according to the chairwoman of the town's Planning and Zoning Commission.

SMART said the plant would be built within the existing gravel pit owned by O&G Industries, which operates Rawson Materials. The remaining acreage, which is largely wooded, would remain undeveloped.

The trash plant would operate next to more than 130 homes on Black Hill Road, School Street Extension, Bedard Road, Sugar Brook Road, Philmar Drive, Jackson Road, Picket Road, Deibler Lane and Karin Drive.

Two schools, nursing homes, Backus Hospital Plainfield Emergency Care Center, Lion’s Park and the town hall are all within 1.5 miles of the project site.

The property is also near Sugar Brook, a Class A water source, which would receive runoff from the trash plant during a greater than 100-year storm event, according to SMART’s permit applications.

What would the trash plant look like?

The site would consist of an an enclosed "tipping building" where trucks would dump an average of 1,800 tons of trash each day into a recessed waste pit. From there, facility staff would remove bulky waste items like furniture and appliances and store them at a "Special Waste Exclusion Building" for disposal at an off-site facility.

Remaining materials are sorted using artificial intelligence-powered machines. Glass and metals are separated and stored for off-site recycling. Electronics and hazardous household waste like paint, batteries and solvents would be sent to the "Special Waste Exclusion Building."

The leftover material would be sized, shredded and assigned to two waste streams. One creates refuse-derived fuel that will be heated and turned to gas for on-site power generation and residual ash collection. The other creates an organic-rich biomass fuel that will be refined into renewable natural gas and liquefied carbon dioxide for the food and beverage industry.

The facility would include a boiler, gasifier, steam turbine generator, substation, anaerobic digester, biogas upgrader, gas storage bladder, carbon capture and refining system and cooling towers.

SMART said the tallest structure on the site would be a boiler stack that would rise approximately 18 stories high. SMART said the technology in the structure is designed to "avoid the visual impact of a winter vapor plume" common in other cooling towers, which can create plumes that are visible from miles away.

At a distance of 1,500 feet from the nearest public roadway, SMART said, noise, lighting and visual impacts would be "well buffered by vegetation and by distance (including trees)."

How would the SMART facility make money?

SMART said the trash plant is designed to "maximize benefits of the circular economy," in which "waste becomes a valuable resource."

The facility would collect a tipping fee for each ton of municipal solid waste that is dumped at the site. A former trash-to-energy facility in Hartford, known as MIRA, charged roughly $110 per ton for disposal until it ceased operations in 2022. If SMART adopted the same rate, its trash plant would collect $51,480,000 a year in tipping fees alone.

The site also has the capacity to generate 45 megawatts of energy, which would be sold back to the electric grid. If the facility operated at that capacity continuously, it would create enough electricity to power more than 50,000 Connecticut homes a day, according to average energy consumption estimates for the state in 2025.

SMART said its facility would produce up to 327 standard cubic feet per minute of renewable natural gas that would be sold and directed into the local utility pipeline. Operating at full capacity, this commodity, which is equivalent to conventional natural gas, could fuel roughly 2,700 homes per day, based on the daily consumption estimates for the average U.S. home.

Additionally the SMART plant would refine, compress and liquify carbon dioxide at the site, which will be "stored, trucked out and sold to the food industry or for other industrial processes," according to SMART's application materials.

Why does the state need a trash plant?

Connecticut has a trash problem.

According to a 2025 report from DEEP, just 58% of Connecticut’s waste is disposed of in-state. In 2023, Connecticut paid millions of dollars to ship 940,000 tons of trash to out-of-state facilities in Alabama, Massachusetts, Michigan, New York, Ohio, Pennsylvania and Virginia. Nearly 90% of this exported trash ended up in landfills, according to the report.

The proposed SMART facility would cut Connecticut’s self-sufficiency deficit in half by processing an estimated 468,000 tons of waste each year.

The trash plant would be the second-largest processor of waste in the state, surpassed only by WIN Waste Innovations, formerly known as Wheelabrator Bridgeport, which received more than 727,000 tons of waste in 2022.

Where would the trash come from?

During the first three years of operations the SMART facility would process a 50-50 mix of trash from municipal and private sources — including out-of-state waste — according to the company’s solid waste permit application.

SMART said local government agencies would receive preferential treatment for contracts, and by year five, 100% of the waste processed at the site would come from municipalities.

In traffic study documents, SMART said it anticipates “increased” deliveries from Hartford-area communities that were previously served by the Materials Innovation and Recycling Authority, the Hartford trash-to-energy plant that closed in 2023.

How would the plant impact traffic?

Roughly 130 dump trucks would enter and leave the facility each day, according to SMART’s traffic study. Approximately 120 of these trucks would carry in municipal waste, and another 10 would collect and remove more than 100 tons of residual ash from the site.

Roughly 150 employees would commute to and from the plant across three shifts.

All vehicles would access the facility via Route 12, at the site of Rawson Materials' current driveway at 349 Norwich Road. An emergency-access-only driveway would connect the site to Route 14 on Black Hill Road.

SMART said all trash deliveries would take place between 6 a.m. and 5 p.m. on weekdays.

How will the trash plant impact air quality?

Annual proposed emissions from the SMART facility would produce the same warming effect as 493,483 tons of carbon dioxide, according to the SMART’s air permit application. That is more than the annual emissions of 107,000 cars, according to estimates from the U.S. Environmental Protection Agency.

Annual proposed emissions from the site would include more than 162 tons of nitrous oxides, 59 tons of sulfur dioxide, 48 tons of carbon monoxide and 19 tons of volatile organic compounds.

Each year, the proposal would also allow the facility to emit 40 pounds of lead particles and 1,840 pounds of Hazardous Air Pollutants — a class of 188 toxic chemicals, heavy metals and other compounds that increase the risk of cancer, infertility, birth defects, immunocompromisation, developmental delays and respiratory issues.

While nearly all of the pollutants would be emitted directly into the atmosphere, SMART estimates that 31.75 tons of particulate matter could end up on the roads as “fugitive dust” from vehicles.

According to the EPA, these small, inhalable particles can bury themselves deep within the lungs and even enter the bloodstream. The EPA said numerous studies link particulate matter exposure to heart attack, asthma, decreased lung function and irregular heartbeat, as well as premature death in individuals with heart or lung disease.

In the addendum to the facility’s environmental justice plan, SMART said its proposal is “structured ... to minimize adverse health impacts or environmental impacts to natural resources in CT.” SMART added that the facility “could not be approved in CT if doing so would threaten adverse environmental or health risks to anyone.”

What is the worst-case scenario modeling?

Under 100% boiler load conditions, an air quality analysis by TRC Environmental Corp. for SMART predicted that the plant could produce higher-than-significant levels of nitrogen dioxide and sulfur dioxide — pollutants that can cause difficulty breathing and contribute to asthma, according to the Environmental Protection Agency.

Under worst-case scenario modeling, TRC said nitrogen dioxide concentrations that exceed significant impact levels could occur in pockets more than 6 miles from the plant. TRC projected that “the overall maximum impact” — 22.1 micrograms of nitrogen dioxide per cubic meter of air for one hour — would be concentrated roughly half a mile west of the plant.

The same modeling predicted that sulfur dioxide levels of up to 22.1 micrograms per cubic meter of air for one hour could extend 1.5 miles from the plant, with the maximum impact concentrated a third of a mile east of the facility.

According to the state’s Ambient Impact Analysis Guide, nitrogen dioxide and sulfur dioxide concentrations are considered significant once one-hour concentrations exceed 7.5 and 7.8 micrograms per cubic meter of air. Pollution levels are considered “adverse” once they cross a threshold of 23 and 25 micrograms per cubic meter for one hour.

Why does SMART say the trash plant has environmental benefits?

By reducing Connecticut’s need to ship trash out of state, SMART said the trash plant will decrease greenhouse gas emissions associated with waste transportation.

SMART said the facility will reduce the amount of trash going to landfills by recovering recyclable materials, converting organic waste into renewable natural gas, generating electricity from refuse-derived fuel, and capturing food-grade carbon dioxide for carbonated beverages.

SMART has also said that the emissions from the plant would amount to just a fraction of those released by any of Connecticut’s existing trash-to-energy facilities in Bridgeport, Bristol, Lisbon and Preston — all of which are more than 30 years old.

Will loosened federal standards impact regulatory policies?

In February, the Trump administration repealed the EPA’s endangerment finding that recognized greenhouse gases as a threat to human health and served as the legal basis for most U.S. climate regulations.

The repeal of the doctrine eliminated the EPA’s authority to regulate greenhouse gas emissions from motor vehicles, and legal experts said fossil fuel-fired power plants and other emitters could soon follow. However, the EPA said it can still regulate “traditional air pollutants” under the Clean Air Act.

Amid this deregulation, the EPA actually tightened emission standards for waste combustion facilities in March. After 20 years of no changes, new and existing trash-to-energy facilities will now need to adapt to stricter limits on nine pollutants, including nitrogen oxides, sulfur dioxide, particulate matter, mercury and lead.

In application materials, SMART has said its “proposed facility will be the lowest emitting MSW-to-energy facility constructed in the US to-date.” SMART specifically designed its plant to match the unofficial emission standards proposed by the EPA in 2024. The finalized emission standards in the 2026 rule — which all new waste-to-energy facilities must adhere to — either match or are slightly more lenient than the levels in the 2024 proposal, depending on the pollutant.

Existing plants, including those in Connecticut, must reduce their emissions within the next five years to meet the new standards.

During a public presentation in August, Jaimeson Sinclair, the division director of air engineering at DEEP, said any permit granted by the state agency is a living document that requires continuous compliance and monitoring.

Sinclair said there have been cases where DEEP has loosened certain permit standards after the EPA loosened select regulations. However, Sinclair said DEEP will “hold fast” to the standards for which they have discretion.
