In Brief

Southern Indiana City Plans Solar Farm

to Power Sewage Plant

BOONVILLE, Ind. (AP) — A southern Indiana city is

aiming to hold down future increases in sewer bills by

building a 4-acre solar farm.

Boonville officials are moving ahead with an estimated

$1.7 million project for the field of nearly 2,000 solar

panels to power its new sewage treatment plant.

The city expects to sell excess electricity that’s generated

to the utility company Vectren. Projections are that

the city will save about $17,000 a month or $6 million

over the next 30 years.

Mayor Charles Wyatt says he’s glad the city about 15

miles northeast of Evansville can use green energy to

reduce expenses for the sewage plant.

Fermi Two Nuclear Plant is Back Online

Following Repairs


power plant in southeastern Michigan is back online

after being shut down last month for repairs.

The Monroe News reports DTE Energy’s Fermi 2 plant

in Monroe County was synchronized to the electrical

grid on Jan. 1.

DTE Energy spokesman Stephen Tait says the plant

“was maintained in a safe, stable condition throughout

the outage.” The plant was taken offline Dec. 6 as

operators looked into an electrical issue on the plant’s

main generator, which is on the non-nuclear side of

the plant. The issue was traced to a ground fault.

The Detroit-based utility’s plant is located along Lake

Erie in Frenchtown Township, near Michigan’s border

with Ohio.

Rock Falls Planners Object to Proposed

Community Solar Farm

ROCK FALLS, Ill. (AP) — Planning officials in a northwestern

Illinois community are opposing a proposed

community solar farm just outside its city limits.

Sauk Valley Media reports that the Rock Falls Plan

Commission recommended that the city object to the

project, saying it is incompatible with comprehensive

plans of the city and Whiteside County.

The proposed project site is in an agricultural area. The

city contends the site should continue to be used for

farming until it can be developed for more traditional

commercial purposes.

Minnetonka, Minnesota-based Sunrise Energy Ventures

has applied to the county for a special-use permit for

the project. Rock Falls has a say in the matter because

the site is within a 1.5-mile radius of its borders.

Rock Falls is about 115 miles (185 kilometers) west of


Michigan’s $52M for Lock May Speed

Construction, Save Money

LANSING, Mich. (AP) — Michigan’s commitment of

up to $52 million toward construction of a new Great

Lakes shipping lock could accelerate the project’s completion

by a year and save taxpayers $30 million.

Gov. Rick Snyder and the U.S. Army Corps of Engineers

released the figures Dec. 26 while announcing a memorandum

of agreement.

Michigan’s funds will be used to pay for design work

and a portion of a channel deepening project that will

be an important step toward building a second largesized

lock at Sault Ste. Marie to accommodate freighters

that haul iron ore and other bulk commodities. The

federal government is spending $32 million on the

channel deepening.

Congress has authorized funding for the second large

Soo Lock but must appropriate funds over numerous

years to pay for the $1 billion project.

Cleanup Set for 200,000 Waste Tires

Left at Indiana Business

ANDERSON, Ind. (AP) — State environmental officials

are stepping in to clean up nearly 200,000 shredded

tires left at a former central Indiana recycling business.

The Indiana Department of Environmental Management

estimates cleaning up the Green Tire Reclamation

site in Anderson could cost up to $262,000 and

will take about a year. The (Anderson) Herald-Bulletin

reports the tires have been cut into 2-inch chunks and

stacked in massive piles on the property that appears


The business opened in 2012 with permission to store

5,000 waste tires it would shred for uses such as being

burned in power plants or as construction fill. But business

owner Dan McKenzie said in 2014 he hadn’t been

able to find buyers for the shredded tires. McKenzie

didn’t return phone calls to comment on the cleanup.

3 Firms Eye Building Wind Energy Turbines

off New Jersey

ATLANTIC CITY, N.J. (AP) — At least three firms are interested

in building offshore wind energy projects off

the coast of New Jersey.

The state Board of Public Utilities says it received three

bids Friday, Dec. 28, from firms interested in building

wind projects, but it wouldn’t identify any of them.

A Danish wind company, Orsted, said it had submitted

one of them.

The state is seeking companies to build projects that

would generate at least 1,100 megawatts of electricity.

Orsted estimates that amount could power more than

a half-million homes.

Another company, Atlantic Shores Offshore Wind, says

it’s interested in developing a project that could provide

up to 2,500 megawatts.

It was not immediately known whether that firm,

which is a joint venture between Shell and EDF Renewables

North America, has formally applied.

DTE Energy Agrees to $840,000 Fine in

Shut-Off Snafu

DETROIT (AP) — A mess over billings and improper

shutoffs has led to an $840,000 fine for DTE Energy.

State regulators approved the settlement early last

month. Sally Talberg of the Michigan Public Service

Commission says the commission has “great concern

when utilities violated consumer protection rules.”

The investigation began a year ago, months after DTE

began using a new billing system. The commission

received complaints that power was being improperly

shut off. More than 4,000 customers did not receive a

proper shut-off notice for nonpayment.

DTE has agreed to refund all deposits and reconnection

fees. The utility also will be audited over its shutoff

procedures until 2020.

A group known as the Residential Customer Group

watched the case and objected to the settlement. Michelle

Rison says the fine isn’t high enough, especially

when some shut-offs occurred during cold weather.

Illinois EPA Offers Grants for Wastewater


SPRINGFIELD, Ill. (AP) — The Illinois Environmental Protection

Agency is offering grants to public wastewater

treatment plants to improve energy efficiency.

The agency has announced $3 million in grant funding.

Grants ranging from $5,000 to $1.5 million will

reduce energy consumption at treatment plants.

EPA Director Alec Messina says the department has

worked with 15 Illinois municipalities for no-cost

efficiency assessments. The grant program uses U.S.

Department of Energy funds to upgrade plants where

the most cost savings will be.

Applications for the grant are available online from

the EPA. Applications are due by Feb. 12, 2019.

The applications will be ranked according to energy

savings per dollar invested, energy rate paid by the

facility and the energy cost to treat one million gallons

of water at the plant.

Renovation to Preserve Courthouse

Once Visited by Lincoln

THEBES, Ill. (AP) — A historic southern Illinois courthouse

once visited by Abraham Lincoln is getting an

$83,000 renovation with help from a private donor.

The Old Thebes Courthouse overlooking the Mississippi

River was built in the 1840s and is listed on the National

Register of Historic Places. Dred Scott, the slave

whose fight for freedom became a landmark Supreme

Court ruling, was held in its jail.

The Southern Illinoisan reports the structure fell into

disrepair after the county seat moved in 1860.

Goins says it “will look like new” when it’s done this

Texas Training for Wind Power Jobs

Literally Has Ups, Downs

By Andrea Leinfelder | Houston Chronicle

In addition to studying hydraulics, welding and electrical

theories during the seven-month program, MIAT students

must learn to safely climb the roughly 300-foot towers and

to rescue their colleagues should something go wrong.

“That way, when they go out in the field, I’ve personally

verified that they can actively protect themselves at height,”

said David Moriconi, lead wind instructor at MIAT.

So Snoddy attached his harness to a cable in the center of

the ladder. He climbed to the top and transitioned to a platform,

which involved unclipping from the cable at his chest

and then clipping a dual-shock-absorbing lanyard to his back.

He then attached a self-retracting line — a yo-yo-like

contraption that would catch Snoddy should he fall — and

unclipped the shock-absorbing lanyard.

All of that had to be done before setting to work, with hand

signals from below indicating that he needed to lift or lower

a set of tools. And then Snoddy climbed back down the ladder

in an equally safe fashion.

He passed with flying colors.

The test earned students a climb and rescue certification

required by many employers.

Tony Robinette, field operations manager for renewable

energy and construction at the staffing firm System One, emphasized

the importance of this climb test, saying the most

catastrophic injuries often come from climbing.

He also applauded MIAT, saying the students are well prepared

when they graduate. It helps that MIAT has a longer

training period than some other programs.

“They definitely come out and hit the ground running,” he


And to make the training more fun, MIAT held a competition

on the eve of its official climb test. Moriconi clocked how

quickly students could climb the ladder five times. That’s

roughly the height of a single section on a wind turbine tower

— and most towers have four sections.

The fastest time was 1 minute, 30 seconds. The slowest time

was around 4 minutes, 30 seconds.

Snoddy came in second place at 1 minute, 56 seconds. Good,

but not entirely satisfying.

“I’m an ex-athlete,” he said, “so I wish I came in first.”

MIAT College of Technology Wind Turbine Instructor David Moriconi, third from right, gives Anthony Snoddy, second from right, instructions before a

ladder exercise in Houston. MIAT College of Technology has a seven-month wind power technician career training program. (Steve Gonzales/Houston

Chronicle via AP)

HOUSTON (AP) — Anthony Snoddy was first to climb the 18-

foot ladder.

The Houston Chronicle reports as the kid who found the tallest

trees and front-flipped off buildings, Snoddy, 36, wasn’t

worried about the height. He knew it would be part of his

job maintaining and repairing wind turbines.

“Just make sure you do everything correctly,” Snoddy told

himself as he approached the ladder.

In 2018, the MIAT campus in north Houston saw a 60 percent

enrollment increase in its wind power technician program,

which averaged 25 to 30 students. The U.S. Bureau of Labor

Statistics expects that the field will grow to 11,400 wind turbine

technicians in 2026, up from 5,800 in 2016.

Instead, he was focused on the safety clamps and procedures

for climbing the ladder. These weren’t part of his riskier

youthful forays, but they were essential in graduating from

MIAT College of Technology and entering a workforce expected

to grow 96 percent between 2016 and 2026.

Many of MIAT’s graduates could be employed in Texas, a hot

spot for wind power. The state leads the nation in wind power

production and has more installed wind power capacity

than all but five countries in the world, according to the U.S.

Energy Department. The American Wind Energy Association

said that in 2017, Texas had up to 25,000 wind industry jobs.

Electric Garage Heaters for a Warm

Workshop By Jim Herring

Most garages are not connected to central heating, making

them a large cold spot in most home heating systems. When

winter comes, an unheated garage can be a cold and unappealing

place for home maintenance, tinkering and other


One way to keep a garage workspace toasty even in the

harshest winters is choosing a top-notch electric garage heater.

Electric heaters offer several benefits over other heating

systems — they don’t require venting like gas heaters and

can be more cost-effective.

Electric Heater Benefits

One factor to consider when heating a garage is safety. Electric

heaters do not pose the same risks as propane or natural

gas heaters. Along with a car, truck or other gas-powered

vehicles, people also store gas, oil and other flammables in a

garage. Because there are no open flames or exhaust fumes

with electric heaters, they’re safer to use around gas vehicles

and lawn tools.

Electric heaters also offer efficiencies that other heaters do

not. With an electric garage heater, every bit of electricity

used is converted into heat. With propane, on the other

hand, only 80 percent of its fuel is used for heat while the

other 20 percent is lost by-products. That fuel loss translates

into inefficiency and can mean higher costs for homeowners.

Electric garage heaters also provide the flexibility to provide

warmth without taking up floor space or creating a tripping

hazard. They can be mounted on the wall or ceiling, and angled

to push warm air horizontally, vertically or in any other

desired direction. These installation and airflow options are

much harder to achieve with a gas garage heater.

Choosing the Appropriate Heater

Whether using the garage for random hobbies or a regular

hangout, there are several electric heating options to choose

from including radiant electric, portable heaters and fanforced


• Radiant electric heaters are designed to target a specific

area with heat, typically using infrared technology to heat

the objects in the room instead of the air.

• Portable heaters are easy to move around the garage, targeting

heat to the necessary spots where one is working.

• Fan-forced heaters move warm air throughout an entire

garage for balanced, all-over heating.

Consider how the heater will be best used in your garage

before making a selection.

Garage Heater Installation Tips

How best to install an electric heater varies depending on

the type. Some models may need to be wired by an electrician

or trained professional, while others are portable and

can be easily mounted and simply plugged in.

Before hooking anything up, be sure to check the voltage

requirements. With a plug-in 120V electric garage heater,

Electric garage heat offers advantages that gas heated garages don’t —

ventilation isn’t a problem, and costs can be lower than for gas heating


for example, all that’s needed is an outlet. An electric heater

that runs at a voltage higher than 120, however, will need to

be wired in. This will require some electrical work.

Also, make sure that the model of heater is sized appropriately

for the space. To ensure a heater is generating enough

High-Speed Rail From St. Louis to

Chicago Faces More Delays

ST. LOUIS (AP) — Railway commuters traveling between St.

Louis and Chicago have yet to see faster rail journeys, despite

most of the Amtrak corridor’s $1.95 billon upgrade concluding

a year ago.

Delays in installing and testing new GPS-related safety technology

kept Amtrak trains from hitting high speeds of 90

mph during 2018, as the Illinois Department of Transportation

originally projected, the St. Louis Post-Dispatch reported.

Trains are not allowed to travel faster than 79-mph on

the route.

The Illinois agency projects that 90-mph speeds will be in

place for Amtrak by the summer from Alton to south of

Springfield. Most of the remainder of the route is expected

to implement 90-mph speeds by the end of this year.

The top speeds will be used only in the more open expanses

of the route outside the St. Louis and Chicago metropolitan


Contractors and crews from Union Pacific Railroad work both above and

below the Wood River Creek railroad bridge Tuesday, May 16, 2017, just

east of the Homer Adams Parkway extension railroad bridge in Alton, Ill.

Workers are replacing the old steel bridge’s deck and working in the creek

below. Pre-assembled sections of concrete railroad ties and track are being

pulled into place to run across the bridge when the deck is finished. The

work is for the new high-speed rail line between Chicago and St. Louis

which is scheduled to be in service by this fall. (John Badman/The Telegraph

via AP)

The Illinois Transportation Department had previously said

speeds of 110 mph would be reached by 2019, but the agency

has stopped offering predictions on when that will happen.

The 110-mph speed would shave about an hour off the

typical 5½-hour Amtrak trip between St. Louis and Chicago.

The project was funded in 2010, largely by federal economic

stimulus dollars allotted under then-President Barack Obama.

Jessie Decker, an Illinois Transportation Department spokeswoman,

said in an email to the St. Louis Dispatch that an

early version of the safety technology, named positive train

control, is in service on most of the 215-mile stretch of the

284-mile corridor owned by Union Pacific.

Decker noted that Amtrak is upgrading software on its trains

to communicate with the positive train control system, which

helps monitor trains’ position and speed. If a train engineer

were to fail to respond to an upcoming signal, the locomotive

would take over control and slow or stop a train to avoid

a crash.

Missourians Want Action Over Too-High

Illinois Levee By Jim Salter

action if the Sny Island Levee District in Illinois fails to reduce

its levee height. FEMA didn’t respond to the alliance but told

The Associated Press it is working to resolve the issue.

Missouri residents have complained for years that the Sny

has been built several feet too high in some spots. The 60-

mile (96.5-kilometer) system is north of St. Louis and protects

roughly 115,000 acres of fertile Illinois farmland.

The upper Mississippi River is lined with levees that protect

towns, businesses and hundreds of thousands of acres of

agricultural land. But in times of flooding, water that would

naturally flow over a flood plain is boxed out and forced

elsewhere. Such redirecting of floodwater is especially

concerning given the increasing volatility of the river, which

has seen damaging flooding far more frequently in recent


Crews check out the 54 mile long Sny Levee that protects 125,000 acres of

prime farmland as the Mississippi River continues to rise south of Quincy,

instances they’re supposed to be topped,” said David Stokes,

executive director of the Great Rivers Habitat Alliance. “You

don’t want to sacrifice a city to keep the farmland dry.”

A study by the Army Corps of Engineers in 2017 found that

40 percent of the 205 miles (330 kilometers) of levees from

central Iowa to St. Louis were built above their authorized

heights. Missouri, Iowa and Illinois all had levees in violation.

The Sny is the longest of those systems and, some Missouri

residents say, the biggest violator. The Corps has said the Sny

is up to 4 feet (1.2 meters) above authorized levels in some


In January 2016, FEMA’s Mitigation Division asked leaders of

the three Illinois counties responsible for the Sny — Pike, Calhoun

and Adams counties — to show permits proving that

raising the levee was authorized.

Three years later, it remains unclear if any permits were


Mike Reed, superintendent of the Sny district, said in an

email to The Associated Press that the levee district is working

with FEMA “to clear up questions that may remain as to

the authorized levee elevation.”

FEMA spokeswoman Cassie Ringsdorf said in an email that

the agency “has been working with the state of Illinois and

the U.S. Army Corps of Engineers to determine the best

course of action to address those issues.”

In the Oct. 8 letter to FEMA Mitigation Division Director

Mary Beth Caruso, Stokes urged FEMA to cut off availability

of insurance through the National Flood Insurance Program

to Illinois property owners behind the Sny unless the levee

height is reduced.

“It’s time to crack down,” he said.

Local farmer Nancy Guyton agreed. Guyton and her husband

grow corn and soybeans on 1,500 acres in the flood plain of

Pike County, Missouri, directly across from the Sny. She said

the too-tall Illinois levee means more significant damage to

the family farm as the murky and often-toxic water sticks

around longer during a flood.

“It’s just a real mess and FEMA can do something about it,”

Guyton said. “They’re dragging their heels. They should have

taken care of this matter several years ago.”

Maryland Board Votes Against Natural

Gas Pipeline Project By Brian Witte

ANNAPOLIS, Md. (AP) — A board of

high-ranking Maryland officials on Wednesday,

Jan. 2, rejected a proposed pipeline

across the western part of the state that

would carry natural gas produced in Pennsylvania

to West Virginia.

The Board of Public Works voted 3-0 against

an easement for TransCanada’s pipeline. It

would run under the Potomac River near

Hanover, Md., and extend about 3 miles

(4.83 kilometers) from Columbia Gas’ network

in Pennsylvania to Mountaineer Gas’

distribution system in West Virginia.

Comptroller Peter Franchot, a Democrat, cited

testimony that the pipeline could bring

Maryland environmental problems without

economic benefits. The board also includes

Maryland Gov. Larry Hogan, a Republican,

and Treasurer Nancy Kopp, a Democrat.

Environmentalists and residents have been

vocal in opposing the pipeline.

Opponents of a proposed natural gas pipeline that would run through Maryland and under the Potomac River hold signs at a rally in Annapolis, Md., urging

Gov. Larry Hogan to reject the project. The bottom line reads: “No Potomac Pipeline.” A board of high-ranking Maryland officials rejected the pipeline

Wednesday, Jan. 2, 2019, that would carry natural gas produced in Pennsylvania to West Virginia. (AP Photo/Brian Witte, File)

noted that Maryland approved a law, which Hogan signed in

2017, to ban the hydraulic fracturing drilling process known

as fracking in Maryland. The process is used to extract natural

gas. Maryland was the first state where a legislature voted

to bar the practice that actually has natural gas reserves.

“Given that Maryland has banned fracking, it defies our

state’s existing energy policy to bring the same public health

risks to our residents by way of a pipeline,” the letter said.

“Moreover, enabling fossil fuel production runs counter to

our state’s goals of increasing renewable energy production.”

The letter, which was sent the week of the meeting, also noted

that the pipeline would affect at least 10 wetlands and 19

streams, in addition to the Potomac River.

While the board delayed a vote on the easement at its last

meeting, Hogan said the unanimous vote would have happened

without the letter from lawmakers.

“It had nothing to do with any letter from the legislature,”

Hogan said at the Jan. 2 board meeting.

Anne Havemann, an attorney for Chesapeake Climate Action

Network, said she hopes the board’s vote marks an end to

the proposal.

“We’ll see if (the Federal Energy Regulatory Commission)

gets involved or the courts get involved, but for now it’s a

welcome delay and we hope a permanent end to this pipeline,”

Havemann said shortly after the vote.

DODGEVILLE, Wis. (AP) — Residents in a rural Wisconsin

county are split over a Chicago developer’s plan to work

with two Wisconsin utilities to build a solar farm that would

include more than 1 million solar panels.

The Wisconsin State Journal reports that the Badger Hollow

Solar Farm proposed by Invenergy would cover 2,700 acres in

Iowa County and could power more than 70,000 homes. The

project is seeking a permit from the Wisconsin Public Service


Ken Wunderlin, a southwest Wisconsin farmer, said he

agreed to have part of the solar farm on his land because

it’s a good financial move. He believes it’s also a chance to

get involved in a more environmentally friendly source of


“I’m a firm believer in the science on global warming,” he

said. “We need to be taking steps to get away from coalfired

power. This is my small opportunity to be a participant.”

Renewable energy advocates have hailed it as a way for utilities

to produce low-cost, clean energy within the state while

providing some $1.8 million a year in rents for hard-pressed

sharecroppers like Wunderlin.

“We think of it as a complete win for the state of Wisconsin,”

said Michael Vickerman, policy director for Renew

Wisconsin. “We’re talking about renewable generation

completely located within the state of Wisconsin. It is clean.

It is quiet. It yields a great deal of financial benefits to the

landowners and the surrounding communities.”

But not everyone in Iowa County is welcoming the development.

Richard Jinkins, a southwest farmer who lives just east of

Wunderlin’s land on a 400-acre farm, said he’s worried that

the farm will destroy the area’s scenic beauty, take up valuable

farmland and cause the county’s 23,687 population to


Jinkins, along with two other nearby farmers, are leading the

charge against the project as it goes through the permitting

process with the Wisconsin Public Service Commission.

“In the best case (it’s) going to make a solar panel wasteland

where nobody’s going to live,” said Jinkins, a computer programmer

who also raises cash crops. “It’s not going to be the

North Dakota Bill Seeks to Discourage

Pipeline Tampering

BISMARCK, N.D. (AP) — A North Dakota legislator wants to

increase the legal consequences for people who tamper with

pipelines and any groups that help them, following a 2016

pipeline protest that shut down oil flow for several hours.

Republican Sen. Janne Myrdal of Edinburg is sponsoring the

bill, The Bismarck Tribune reported.

The legislation would more clearly define that it’s illegal to

damage energy facilities and other critical infrastructure,

such as refineries, electrical power generating facilities or

natural gas processing plants.

It also would increase maximum fines from $10,000 to

$100,000 if an organization is found to have conspired with

individuals who tamper with infrastructure.

The bill wouldn’t prevent the “lawful assembly and peaceful

and orderly petition for the redress of grievances.”

“We worked hard on it to make sure that no First Amendment

rights are trampled on whatsoever in this bill,” Myrdal


Myrdal said the bill was inspired by the October 2016 pipeline

protest involving TransCanada’s Keystone Pipeline, when

activists turned an emergency valve and shut down oil flow.

Seattle resident Michael Eric Foster, who served jail time for

turning the pipeline valve during the protest, said a more

stringent law wouldn’t have stopped him.

“What I did, I did to protect my family because everything

else is failing. I owe it to my family tree and yours to do

whatever we can think of to stop destroying this place for

our kids,” Foster said.

Foster said the bill is an attempt to “silence and intimidate

and harass people who are looking out for the public good.”

Masonry Gives Construction Students

Hands-On Training By Andrew Wind | Waterloo-Cedar Falls Courier

WATERLOO, Iowa (AP) — Students in Wayne Lidtke’s sustainable

construction and design class have learned about house

building by doing it.

They’ve framed walls, hung drywall, installed windows and

doors, and done minimal wiring while building small scale

houses at the Waterloo Career Center. The students will be

working on some other skills, like roofing, in the Waterloo

Community Schools’ program before the semester is over, the

Waterloo-Cedar Falls Courier reported.

Though, the nine high schoolers put down their hammers

and picked up trowels. Iowa Masonry Institute members

taught them lessons on mixing mortar and building a number

of structures with cinder block and brick.

Their task was to construct a pier. The column-like structure

can support a beam in a building, an overhang on an entryway

or have a more decorative use at the end of a driveway.

Students shoveled mortar out of wheelbarrows onto plywood

platforms. They scooped up the substance with their

trowels, depositing it on the edges of a pair of cinder blocks

before adding another layer of blocks.

“You put a lot of mortar there so you have a lot of contact,

just so in a couple years it doesn’t fall apart,” said Hunter

Pierce, a West High School senior.

Chris Busch, overseeing the students’ efforts, emphasized the

importance of getting the right amount of mortar between

the blocks.

“That joint is an integral part of the unit,” noted the Marshalltown-based

Bricklayers & Allied Craftworkers union

training director. Ideally, he said, the mortar level will be

about three-eighths of an inch.

Without the right amount, “it’ll start to lose considerable

integrity,” said Busch. “Three-eighths is kind of that sweet

Students were building the piers five blocks high. “Then,

they’re going to veneer it with brick,” he explained.

‘Heated’ about your chiller’s performance?


We’ve got you covered with


and 80 YEARS






As one of the students got several blocks high, Busch offered

a bit of advice: “You can use your level to check that, check

for level (horizontally) and plumb (vertically)” to ensure

everything is straight and level.

“It’s fun, it’s something to do,” said West High junior Nathan

Elliott, of learning the skill. “Better than sitting in there on a

computer. I like the hands-on stuff.”

Pierce also likes learning this way and said he would consider

working in construction.

Those are the sorts of responses Busch hopes for from his

training sessions at schools.

“This is basically part of our recruitment,” he said. Students

started with basics like learning how to spread mortar, lay

brick and use a level. They also built a low wall earlier.

Busch doesn’t expect everyone in the class to end up as a

bricklayer. But bringing the program into schools is important

to finding the next generation of workers — and the

amount of time they’ve had at the career center only helps.

“This is great having a whole week in here to present masonry

to kids,” he said.

Reinventing Fire Detection in Industrial


The cost of a fire in a warehouse goes far beyond the loss

of the building and goods. The consequential loss caused by

downtime, operation interruption, business reputation and

goodwill can be significant.

Modern goods also tend to have increased flammability, in

addition to the presence of large amounts of packing materials

such as plastics, cardboard, wooden crates and pallets.

There are various possible ignition sources in warehouses including

smoking, lighting, electrical equipment and heaters.

Although sprinklers are typically installed in warehouses, the

lack of an appropriate early warning smoke detection system

can not only compromise the safety of the facility but also

that of adjacent buildings.

Fortunately, protecting life and inventory is much easier for

even the largest warehouses as aspirating smoke detection

(ASD) technology becomes more widely adopted. The process

draws in air samples through durable piping to detectors and

tests it using sophisticated laser-based technology, imaging,

and photodiodes. Far from new, the core technology

has been used for decades in sensitive applications such as

cleanrooms and data centers where early smoke detection is


ily diluted. This makes detection difficult for conventional

detection technologies where smoke must build up to certain

levels before the alarm sounds. Furthermore, before sprinklers

are triggered, sufficient heat needs to be generated by

the fire — by which time, it is well underway.

Because of these concerns, traditional spot smoke detectors

are usually considered unsuitable for warehouses with high

ceilings. The installation, wiring, testing, and maintenance of

such spot detectors make them inconvenient and costly.

For instance, regularly testing the smoke detectors requires

having an inspector introduce smoke into the devices. This

requires safely lifting the inspector to the level of the detector

on a scissor lift, cherry picker, or other access equipment,

which adds to inspection costs. Maintaining and repairing

the smoke detectors is similarly costly.

Compared to traditional spot smoke detectors and other

technologies, this approach dramatically improves warehouse

facility safety by detecting smoke at the earliest possible

stage via numerous sampling points, while reducing false

alarms and maintenance.

Industrial-Sized Smoke Detection Challenges

Warehouses come in a wide range of sizes and contain a wider

range of goods. Most large warehouses have high ceilings

of over 40 ft. (12 m), with some modern automated high rack

storage facilities having ceiling heights over 130 ft. (40 m).


The situation is even more challenging in facilities that

operate 24/7, where maintenance is only allowed during a

planned maintenance period.

Linear heat cables and flame detectors are sometimes suggested

offered as a solution and might be tempting from a

maintenance point of view. However, their detection point

(i.e. the flaming stage of fire) is too late to be truly considered

as early warning or adequate detection.

Optimizing Warehouse Smoke Detection

The problem is that in these conditions any smoke is heav-

Instead, as an alternative, ASD technology is a more effective,

early detection option that does not require physical

maintenance to access warehouse ceiling areas above high

bay racks.

Because of such flexibility, ASD smoke detection accommodates

irregular ceiling structures. Moreover, the technology

is not affected by forklifts, robotic gantries, and internal

business operations. Finally, it can even provide detection

within storage racks for the fastest possible response to a fire


As an example, one system, called VESDA-E VEU, by Xtralis,

a global provider of aspirating fire detection equipment,

draws air samples in a continuous process through holes in

long runs of durable industrial pipe mounted along the walls

and ceiling.

While some ASD products use an LED light source and one

or more photo receivers, the VEU utilizes a flair detection

chamber that uses a short wavelength laser, a CMOS imager,

and multiple photodiodes.

Direct imaging of the sampled particles using the CMOS

camera allows data regarding its size, color and shape to be

derived. Additional data from five photodiodes allows measurement

of light scatter in different directions.

With more detailed information to analyze, the unit is able

to differentiate smoke from other factors that could cause

disruptive false alarms. For warehouse environments where

airborne dust particles may also be present, which can be

confused as smoke by some systems, the unit’s dust rejection

and data analytics minimize nuisance alarms by at least 3

times compared to similar technologies.

Compared to even other aspirating technologies, the system

significantly saves on maintenance costs by allowing long

pipe runs up to 1,310 ft. (400 m) and branched pipe networks

up to 2,625 ft. (800 m) to extend detector coverage. This

reduces the number of detectors required to protect a single

fire zone in a warehouse facility.

Unique Warehouse Challenges

Certain types of warehouses in difficult environments may

still require a high level of fire protection, while posing

unique challenges to smoke detection systems.

Freezers & Refrigerated Storage

While most warehouses with freezers or refrigerated storage

have some form of automatic doors or plastic barrier curtains

to limit warm air ingress, it is inevitable that warm air will

enter the room. This often creates condensation within the

room, which causes icing on ceiling-mounted equipment and

structures close to the entry points.

Even though ASD technology is generally accepted as the

best solution for refrigerated storage facilities, there are

some typical problems associated with its application in such


Over time, ASD sampling points and pipe within the sub-zero

area can become blocked causing air flow issues and inoperative

detection of smoke. In some instances, the only solution

is to remove the iced up section of the ASD pipe network

and fit a new pipe.

To combat this issue, some providers offer a unique sampling

arrangement that is specifically designed for refrigerated

storage facilities.

For example, Xtralis enables ASD air sampling pipe to be

installed, inspected and maintained outside the refrigerated

environment (i.e. within roof space). This makes it less prone

to blockage due to icing, easier to inspect, and provides a

more robust, longer lasting installation.

Dusty Warehouses

Certain warehouses are very dusty or highly contaminated

environments such that the performance, longevity and

maintenance of the detection equipment are a real concern.

For these environments, ASD systems exist that are design to

withstand the harsh environments in industrial applications,

have superior dust filtration and are enclosed in NEMA 4

equivalent enclosures.

The Xtralis’ VESDA VLI system, for example, comes in an

International Protection Marking IP66 enclosure that provides

total protection against the ingress of dust and strong

water jets. The unit also is designed with a patented intelligent

filter that significantly reduces the amount of contaminants

entering the detector. An integral secondary filter and

sub-sampling probe also rejects larger dust particles, which

further safeguards against nuisance alarms and extends

detector life.

Protecting the Warehouse Bottom Line

Some managers of warehouse facilities may be inclined to

use spot smoke detectors or other traditional devices because

of their familiarity with such systems.

However, those who take advantage of the superior capabilities

of ASD systems will protect lives and inventory to a degree

not previously possible in warehouse settings. This level

of protection will also prevent serious supply chain disruption

as well as liability and litigation in worst-case scenarios.

Michigan Roadwork to See Increased

Risks, Costs in Winter By Shawn D. Lewis | The Detroit News

DETROIT (AP) — The pushing of Michigan’s roadwork into

the colder months comes with great costs and risks for two

of the area’s biggest projects.

MacDonald said the cost for heating and enclosing concrete

pavement is approximately 30 to 50 percent of the cost of

the material and labor, “depending on a number of factors.”

Work laying concrete has continued on Interstate 696 in

Macomb County and Interstate 75 in Wayne County despite

temperatures below or at 40 degrees, which, according to

the American Concrete Institute, is the temperature for

which measures to prevent freezing must be addressed.

Costly precautions must be in place, including protecting

fresh concrete from freezing by placing heaters along a

route to ensure the concrete will take.

“Nobody wants to build roads in the winter,” said Kevin

MacDonald, a principal engineer with Minnesota-based Beton

Consulting Engineers.

In other words, he said, for every dollar spent on a road project

conducted in July, it will cost between $1.30 and $1.50 in

the winter.

“Modern highway construction in cold, wet climates requires

highly durable, as well as high-strength concrete,” he told

The Detroit News. “This can be achieved in cold weather, so

long as precautions are taken to ensure that the concrete has

adequate strength.”

But MacDonald noted taxpayers usually are not footing the

bill for the higher costs.

“Typically, these types of costs fall into means and methods

over the contractor,” he said. “As such, the contractor will

bear the cost.”

A Michigan contractor working on one of the major road

projects said his employees are using necessary precautions,

and they are being closely monitored by the Michigan Department

of Transportation to minimize the risk.

News, Robin Buckson, File)

Joe Goodall, vice president of Dan’s Excavating Inc. in Shelby

Township, which is working on the I-75 project, said yes, contractors

are working to prevent the ground from freezing.

Goodall said workers are “covering the concrete when temperatures

look to be dropping below freezing overnight or

throughout the following days. The specifications for cold

weather protection are being met on the project.”

The construction work is happening later in the season

because the projects were delayed in September when the

Michigan Infrastructure and Transportation Association

instituted a work stoppage after multiple failed attempts to

bargain a new contract with the Operating Engineers Local

324. A prior, five-year deal expired in June.

The construction rift prompted the shutdown or partial halt

of 89 Michigan Department of Transportation projects and

75 local projects.

“We are bound by contract with MDOT to complete the project

in a time frame, with the lockout and inclement weather

after the lockout, we are continuing to complete the project

in a timely manner.”

MDOT spokesman Jeff Cranson said state inspectors perform

quality assurance on all contractor efforts throughout a


“So among other things, the inspectors will ensure the heating

and housing is correct,” he said. “Ultimately, the contractor

is responsible for the work completed, and a job is not

accepted until MDOT engineers are confident in the quality.”

And so far, Operating Engineers 324 spokesman Dan McKernan

said he has not heard any complaints from contractors

about corners being cut to get the jobs done.

“Certainly, there is frustration from the workers for having

to work through the winter when it didn’t have to be

this way,” McKernan said. “But I talked to the agent who

oversees the road workers, and there haven’t been any complaints.

At the end of the day, MDOT oversees everything,

and they are very strict.”

The American Concrete Institute recommends specific measures

in its “Guide to Cold Weather Concreting,” noting that

“the necessary degree of protection increases as the ambient

temperature decreases.”

Cold weather concreting “results in extra costs because of

potentially lower worker productivity and additional needed

products such as insulating blankets, tarping and heaters.”

But it adds that these measures also most likely will allow a

project to stay on schedule.

Detroit averages highs of 36.1 degrees and lows of 24.1

degrees in December, according to date from the National

Weather Service in White Lake Township.

Daniel DeGraaf, executive director of the Michigan Concrete

Association, said placing heaters is a major element of

keeping the ground warm. A hydronic heater is used to heat

frozen ground or concrete surfaces by pumping heated fluid

through closed-circulation tubing and a heat exchanger.

“The ground cannot be frozen when building a road on top

of it,” he said. “It can be very expensive.”

He presented an analogy.

Blower Wheels

V Belts


And More

But Cranson acknowledged risks when concrete is worked on

in the winter.

He released details that noted: “The top couple inches

(estimated) of the concrete below the exposed surface could

potentially act as a sacrificial layer, protecting the inner concrete

mass from frost-related structural damage. But, if not

protected from the cold weather exposure, this top exposed

surface could undergo irreversible damage as it freezes. Over

time, this damaged concrete surface will erode and scale

away, ultimately resulting in loss of the pavement surface.”

Additionally, the details noted, “Placing concrete pavement

on a frozen base could result in significant loss in structural

support as the base begins to thaw in the spring. As the base

freezes, the moisture within it will expand, thus, causing the

base to heave up (water expands approximately nine percent

in volume as it freezes). When the base thaws, it returns to

its original elevation. This will, in turn, take the pavement

downward with it.”

Cranson summed up the lengths being taken to ensure quality

work on roads during the winter by saying: “Contractors

and the MDOT engineers overseeing their work continue

to work very hard to ensure a commitment to quality while

they also work as quickly as possible to make travel lanes

accessible to the public.

“It is a difficult balancing act in ideal conditions, let alone

in inclement weather. Please keep in mind that the people

fixing and building our roads are our sisters, brothers, friends

and neighbors.”











“Imagine running a furnace with the doors and windows

wide open,” he said. “Not only do they have to heat the

ground, but you can’t go as far with the work as you can on

a fall day because you’re limited by how far the equipment

can stretch.”

Meanwhile, Cranson said state inspectors will hold contractors

accountable for the quality of the concrete.

“All materials must meet specifications,” Cranson said.

“Inspection to ensure specification compliance; and enforcement

based on significant research and testing.”

New Mexico May Reconsider Decision

on More Natural Gas Wells By Morgan Lee

SANTA FE, N.M. (AP) — New Mexico oilfield regulators

announced Friday, Jan. 4, that they may revisit a decision to

ease restrictions on natural gas well locations for a Texas-based

company operating in the northwest corner of the


The announcement came as state oversight of wells shifts

to the Democratic administration of Gov. Michelle Lujan


The state’s Oil Conservation Commission scheduled a public

meeting the following week regarding the approved application

from Hilcorp Energy to increase potential well density in

the San Juan Basin area from four wells to eight per 320-acre

tract, or about half a square mile (1.2 square kilometers).

Environmentalists estimate the density decision could concentrate

patterns of oil well development across hundreds of

square miles (square kilometers) of territory.

In a statement Jan. 4, Hilcorp said it would defend the state’s

ruling last year on well densities and highlighted the related

opportunity for new jobs and investments in an economically

depressed region of the state.

“Hilcorp prevailed in this matter by presenting a scientifically

sound case in accordance with all laws and regulations,” it


Hilcorp has said longstanding density limits have prevented

the company from tapping more of a formation called the

Blanco-Mesaverde gas pool.

The approval of the company’s application to increase well

densities late last year prompted an outcry from conservationists

and a rebuke from the state’s independently elected

land commissioner who left office Dec. 31.

Upon taking office last month, Democratic Land Commissioner

Stephanie Garcia Richard urged the state to take up her

agency’s request for an appeal that was rejected by oilfield

regulators as termed-out Republican Gov. Susana Martinez

left office on Dec. 31.

“It is imperative that we make a decision in the region that

ensures long-term sustainability and production that is fair to

every producer in the state,” Garcia Richard said in a statement

Jan. 4.

The State Land Office oversees 14,000 square miles (36,000

square kilometers) of land and additional underground

resources that are used to help fund schools, universities,

hospitals and other public institutions.

The membership of the Oil Conservation Commission is determined

by the governor, a Cabinet secretary and the state

land commissioner.

New Mexico’s first female state land commissioner, Stephanie Garcia Richard,

speaks after taking the oath of office on Jan. 1, 2019, at the state Capitol

in Santa Fe, N.M. Women including newly inaugurated Gov. Michelle

Lujan Grisham helped Democrats consolidate control over all statewide

offices and New Mexico’s congressional delegation in November elections.

The land commissioner oversees oil and gas drilling, renewable energy

projects and other development across millions of acres of state trust land.

The San Juan Citizens Alliance, an environmental advocacy

group, also has sought a rehearing of the well-density

decision, arguing that it was unfairly shut out of application

proceedings where it hoped to provide testimony about

public-health and environmental impacts.

Erik Schlenker-Goodrich, an attorney for the Alliance, called

the planned meeting a positive development.

“There’s an opportunity to rebuild the credibility of the Oil

Conservation Commission and to ensure that the public has a

voice in oil and gas regulation,” he said.

designed to save

both water and energy

at new facility

Behind the scenes of the most cutting-edge genetic science

lies the work and expertise of companies like New England

BioLabs, Inc. based in Ipswich, Mass.

Since the 1970s, New England BioLabs has provided enzymes

for use in molecular biology research and clinical trials, serving

a network of customers internationally.

The enzymes produced at New England BioLabs are used

in applications like cloning, DNA modification and protein

analysis — applications which are highly precise, requiring

components that are predictable, repeatable and of the

highest quality.

To better serve the ever evolving needs of their customers,

New England BioLabs (NEB) has recently completed the

construction of a 40,000 square foot cleanroom production

facility in Rowley, Mass.

The Right Construction Team

Pulling it all together was the project management firm,

Columbia Construction Company, a Boston-based company

with over 90 years’ experience in multiple sectors: academic,

life sciences, corporate, healthcare and hospitality.

Neal Swain, project manager, explained, “Columbia was

involved with the construction of NEB’s new facility for the

entire process, from design review to final commissioning.”

Columbia worked with AHA Consulting Engineers, Inc.

(AHA) for building’s engineering infrastructure, including

the plant’s process cooling mechanical system. AHA’s clients

include companies such as Vertex, Takeda, Merck, and NEB

itself, as AHA served as the design engineers for its main


As is customary in the industry, AHA worked with suppliers

to find the right equipment to meet the NEB’s specific

requirements. Manufacturer’s rep firm, Fluid Equipment

Solutions of New England (FES), provided technical assistance

for the cooling system at this new facility.

Tight Tolerances for Cooling

Accurate and robust temperature control of the equipment

and environment is critical to the success of the tightly-controlled

manufacturing processes.

A key component of the cooling system that meets the

stringent cooling needs at NEB’s facility is its fluid cooler,

a 1.6 million BTU closed circuit cooling tower designed

to provide cooling to process water for a wide variety of

sophisticated plant processes.

“The fluid cooler provides condenser water to one side of

a heat exchanger,” said Thomas Joyner, partner, and AHA

project manager. “The process water on the other side of

the heat exchanger serves several pieces of plant equipment

as well as a process chiller to provide chilled water for


For such a large, yet critical piece of the cooling puzzle,

AHA considered several options for the fluid cooler. With

the rising cost of energy and concern about water consumption,

the amount of electricity and water used was

an additional factor in deciding which cooling system to


Ben McLaughlin, sales engineer at FES said, “We compared

the performance of multiple evaporative fluid coolers in

terms of meeting the required temperature as well as energy

and water use.”

This tight control is what gives NEB the level of utility savings

as well as the consistency and predictability needed for their

manufacturing processes.

Eco-friendly Accessories

The other key evaporative cooling system components are

the water treatment, and the quiet fan, also selected by the

design team. Although water treatment is necessary to maintain

evaporative cooled equipment during wet operation,

a substantial benefit to a primarily dry cooler is that scale

cannot form when the unit is operating in dry operation.

To prevent scale buildup or corrosion from deposits when

water is evaporated in the cooler, the water must be treated.

In order to maintain an environmentally friendly manufacturing

facility, a non-chemical treatment system was provided

for this evaporative water.

Expert hands bring together the cooling tower assembly at New England

BioLab’s new facility.

After careful analysis, EVAPCO’s eco ATWB-H series hybrid

fluid cooler was selected. The system is specifically designed

to optimize both the evaporative (latent) and dry (sensible)

modes of cooling simultaneously — combining the advantages

of an evaporative cooler and a dry cooler into one unit.

A Balancing Act

McLaughlin explains, “There were three aspects of the fluid

cooling system that were critical for this application. The first

was the cooling tower’s wet and dry performance.”

The hybrid fluid cooler has both wet and dry operation with

the ability to handle full capacity in “dry mode” up to an

ambient dry bulb temperature of 50oF. This reduces water

consumption for every hour of operation below 50o when

the water is turned off and the fan alone is doing all the


“In addition to water savings, the five-horsepower spray

pump is turned off during dry cooling, and that results in

energy savings when compared to the standard fluid cooler

using evaporative cooling only,” said McLaughlin. “So we

have about 60 percent less water used and a 30 percent

reduction in electricity consumption.”

Process water first enters the dry coil which is outside the

evaporative water spray stream. This coil serves to pre-cool

the high-temperature water. The cooled water then enters

the coil, just below the spray stream. Depending on the dry

bulb temperature, the spray pump may be on or off.

A key benefit of the dry coil, piped in series with the wet

coil, is that the evaporation rate off of the wet coil is maximized

because a significant portion of the heat load from

the process has already been rejected by the dry coil before

entering the wet coil. This means that water is always saved,

even when spray pumps are required for full load.

The additional dry coil also allows for reduced water vapor

leaving the cooling tower, which happens because of

efficient transfer of heat from the process water to the moist

air leaving the cooling tower. Increasing the temperature of

the air leaving the tower, without adding moisture, reduces

its relative humidity from a saturated state (at 100 percent),

which greatly reduces the visible plume.

In order to get the most out of this hybrid system, the fan

and spray pump operation are controlled to maximize

savings. The SAGE® control system provided with the cooler

plays a key role in optimizing water and energy savings.

“The controller leverages outdoor or ambient conditions,”

explained McLaughlin. “Specifically, the wet bulb and dry

bulb temperatures are used to best meet load requirements

while reducing water and energy consumption. This sophisticated

operation is handled in stride by the SAGE control

“We included the Pulse-Pure® non-chemical water treatment

system with the fluid cooler,” McLaughlin explained. “This

system uses a high-frequency electromagnetic pulse to take

care of the corrosive or scale-forming solids that would otherwise

concentrate on the cooler’s components when water

evaporates. It also takes care of anything biological that

we’re usually concerned with because it renders microorganisms

incapable of reproduction.”

In addition to reducing chemicals used on site, the unit itself

produces less sound pollution. The super-low sound fan

selected boasts a 9- to 16-decibel reduction in sound when

compared to the standard fluid cooler fan.

“The reduction in sound is concentrated in the low-frequency

octave band, which travel further distances and penetrate

structures,” explained McLaughlin, “so these are the fans

specifically designed for applications that are sound-sensitive

in nature.”

With EVAPCO’s hybrid fluid cooler serving the manufacturing

process, New England BioLabs’ new cleanroom production

facility achieves both high-quality product and lower water

and energy consumption.

“We took the shell of a building and turned it into a 40,000

square foot cleanroom production facility,” said Swain,

“and the process cooling system assures utility savings while

delivering predictable outcomes for NEB’s customers, both

existing and those we expect to serve in the future.”

Connecticut Taps Nuclear Plants to

Generate Clean Energy

HARTFORD, Conn. (AP) — Nuclear power plants in Connecticut

and New Hampshire made the list of electricity producers

selected Dec. 28 to generate the clean energy needed to

help meet Connecticut’s goals for reducing greenhouse gas


Department Energy and Environmental Protection Commissioner

Robert Klee and Democratic Gov. Dannel P. Malloy

announced the state also chose bids submitted from nine

solar projects and one offshore wind project. Final regulatory

approval of power contracts, which still need to be negotiated,

are still required.

“The selection of this diverse portfolio of zero-carbon resources

ensures that Connecticut is doing its part to address

climate change,” Klee said. A 2017 state law required DEEP’s

commissioner to solicit proposals for up to 12 million megawatt-hours

of clean energy annually to meet the state’s

renewable energy goals.

Virginia-based Dominion Energy had sought for months

to have its Millstone Nuclear Power Station in Waterford,

Connecticut, included in the clean energy procurement. Dominion

had argued that the plant faced closure due to rising

expenses and competition from natural gas.

“We look forward to executing the contract with Connecticut’s

utilities shortly,” he said.

State regulators recently determined Millstone was at risk of

early retirement, a move that ultimately allowed the plant to

be part of DEEP’s clean energy auction.

DEEP also selected nine solar projects, including three in

Connecticut, four in Maine and two in New Hampshire.

Additionally, DEEP announced plans to expand upon its June

selection of 200 megawatts of energy generated by the Revolution

Wind offshore project being developed by Rhode Island-based

Deepwater Wind. DEEP said the state will procure

an additional 100 megawatts of power from the wind farm,

located in federal waters, about halfway between Montauk,

N.Y., and Martha’s Vineyard, Mass.

“Offshore wind is fast becoming a centerpiece of Connecticut’s

renewable energy future,” said Jeffrey Grybowski, Co-

CEO of Ørsted US Offshore Wind, which acquired Deepwater

Wind in October. “We’re proud that our Revolution Wind

project will now deliver even more clean energy to Connecticut


A top Dominion executive said Dec. 28 that the company is

pleased Millstone is part of the portfolio. DEEP selected a 10-

year bid for about 50 percent of the entire nuclear facility’s

output. DEEP also selected a bid from the Seabrook Nuclear

Power Plant in New Hampshire.

“DEEP’s decision is good news for Connecticut’s economy and

the environment,” said Paul Koonce, EVP, president and CEO

of power generation at Dominion Energy. He said Dominion’s

“zero carbon offer brings at least $670 million in net

benefits to Connecticut customer” and “welcome holiday

news” for the power plant’s 1,500 employees.

Dakota Access Pipeline Developer Slow

to Replace Some Trees By Blake Nicholson

BISMARCK, N.D. (AP) — The developer of the Dakota Access

oil pipeline missed a year-end deadline to plant thousands

of trees along the pipeline corridor in North Dakota, but

the company said it was still complying with a settlement of

allegations it violated state rules during construction.

Texas-based Energy Transfer Partners, which built the $3.8

billion pipeline that’s now moving North Dakota oil to

Illinois, is falling back on a provision of the September 2017

agreement. The provision provides more time should the

company run into problems providing 20,000 trees to county

soil conservation districts along the pipeline’s 359-mile

(578-kilometer) route across North Dakota.

The deal with North Dakota’s Public Service Commission

settled allegations that ETP removed too many trees in some

areas and that it improperly handled a pipeline route change

after discovering Native American artifacts. The artifacts

were not disturbed.

The agreement required the company to replant trees and

shrubs at a higher ratio in the disputed areas, along with an

additional 20,000 trees along the entire route. ETP filed documents

in October detailing efforts by a contractor to plant

141,000 trees and shrubs, but the PSC asked the company

a month later to provide more documentation that it had

complied with all settlement terms.

tricts due to several factors, including equipment and staffing

issues, difficulties finding willing landowners and poor

planting conditions, according to Perennial Environmental

Services, which ETP hired to handle the work.

A soil conservation district in one of the seven counties

refused to participate at all because it didn’t feel any of the

15 tree species identified in the settlement agreement were

suitable for the county.

The agreement allows for the work to continue into 2019 if

there are problems with the tree supply “or other market

conditions.” Soil conservation districts in six counties have

committed to planting about 16,800 more trees in 2019, for

a total of more than 25,500, according to Perennial Environmental


PSC officials weren’t available at press time for comment on

whether the state thinks ETP is justified in prolonging the

plantings into the new year.

Under the agreement, ETP also was directed to develop an

industry handbook on properly handling pipeline route adjustments

and to conduct training. In return, the PSC didn’t

require the company to admit wrongdoing and scrapped a

proposed $15,000 penalty. The agency has the power to levy

up to $200,000 in fines.

Auto-renewal of your annual membership is now available

and easily managed from your phone or other device.

What do I need to do?

Company attorney Lawrence Bender recently submitted a

report from contractor KC Harvey Environmental further detailing

the replanting efforts in the disputed areas. He noted

that in some areas where landowners refused trees, the trees

were reallocated to other landowners “who had the space

and desire to accommodate more plantings.”

Bender in December detailed training that he said surpassed

what was required during the Williston Basin Petroleum Conference

in May, the North Dakota Petroleum Council annual

meeting in September and the Colorado Oil and Gas Association

Army Looks for a Few Good Robots,

Sparks Industry Battle By Matt O’Brien

CHELMSFORD, Mass. (AP) — The Army is looking for a few

good robots. Not to fight — not yet, at least — but to help

the men and women who do.

These robots aren’t taking up arms, but the companies making

them have waged a different kind of battle. At stake is a

contract worth almost half a billion dollars for 3,000 backpack-sized

robots that can defuse bombs and scout enemy

positions. Competition for the work has spilled over into

Congress and federal court.

The project and others like it could someday help troops

“look around the corner, over the next hillside and let the

robot be in harm’s way and let the robot get shot,” said Paul

Scharre, a military technology expert at the Center for a New

American Security.

The big fight over small robots opens a window into the

intersection of technology and national defense and shows

how fear that China could surpass the U.S. drives even small

tech startups to play geopolitics to outmaneuver rivals. It also

raises questions about whether defense technology should

be sourced solely to American companies to avoid the risk of

tampering by foreign adversaries.

Regardless of which companies prevail, the competition

foreshadows a future in which robots, which are already familiar

military tools, become even more common. The Army’s

immediate plans alone envision a new fleet of 5,000 ground

robots of varying sizes and levels of autonomy. The Marines,

Navy and Air Force are making similar investments.

“My personal estimate is that robots will play a significant

role in combat inside of a decade or a decade and a half,”

the chief of the Army, Gen. Mark Milley, said in May at a

Senate hearing where he appealed for more money to modernize

the force.

Milley warned that adversaries like China and Russia “are

investing heavily and very quickly” in the use of aerial, sea

and ground robots. And now, he added, “we are doing the


Such a shift will be a “huge game-changer for combat,” said

Scharre, who credits Milley’s leadership for the push.

The promise of such big Pentagon investments in robotics

has been a boon for U.S. defense contractors and technology

startups. But the situation is murkier for firms with foreign


Concerns that popular commercial drones made by Chinese

company DJI could be vulnerable to spying led the Army to

ban their use by soldiers in 2017. And in August, the Pentagon

published a report that said China is conducting espionage

to acquire foreign military technologies — sometimes

by using students or researchers as “procurement agents and

intermediaries.” At a December defense expo in Egypt, some

U.S. firms spotted what they viewed as Chinese knock-offs of

their robots.

The China fears came to a head in a bitter competition

between Israeli firm Roboteam and Massachusetts-based Endeavor

Robotics over a series of major contracts to build the

Army’s next generation of ground robots. Those machines

will be designed to be smarter and easier to deploy than the

remote-controlled rovers that have helped troops disable

bombs for more than 15 years.

The biggest contract — worth $429 million — calls for

mass-producing 25-pound robots that are light, easily maneuverable

and can be “carried by infantry for long distances

A Centaur robot rests on a carpeted floor between desks at Endeavor Robotics in Chelmsford, Mass. The Army is looking for a few good robots. These

without taxing the soldier,” said Bryan McVeigh, project

manager for force projection at the Army’s research and

contracting center in Warren, Michigan.

Other bulkier prototypes are tank-sized unmanned supply

vehicles that have been tested in recent weeks in the rough

and wintry terrain outside Fort Drum, New York.

A third $100 million contract — won by Endeavor in late

2017 — is for a midsized reconnaissance and bomb-disabling

robot nicknamed the Centaur.

The competition escalated into a legal fight when Roboteam

accused Endeavor, a spinoff of iRobot, which makes Roomba

vacuum cleaners, of dooming its prospects for those contracts

by hiring a lobbying firm that spread false information

to politicians about the Israeli firm’s Chinese investors.

The lobbying firm, Boston-based Sachem Strategies, circulated

a memo to members of the House Armed Services Committee.

Taking up Endeavor’s cause was Rep. Seth Moulton, a

Massachusetts Democrat — and, like Bielat, a Marine veteran

— who wrote a letter to a top military official in December

2016 urging the Army to “examine the evidence of Chinese

influence” before awarding the robot contracts.

Six other lawmakers later raised similar concerns.

Roboteam CEO Elad Levy declined to comment on the dispute

but said the firm is still “working very closely with U.S.

forces,” including the Air Force, and other countries. But it’s

no longer in the running for the lucrative Army opportunities.

Endeavor is. Looking something like a miniature forklift

on tank treads, its prototype called the Scorpion has been

zipping around a test track behind an office park in a Boston


The only other finalist is just 20 miles away at the former

Massachusetts headquarters of Foster-Miller, now a part of

British defense contractor Qinetiq. The company did not

respond to repeated requests for comment. The contract is

expected to be awarded in early 2019.

Both Endeavor and Qinetiq have strong track records with

the U.S. military, having supplied it with its earlier generation

of ground robots such as Endeavor’s Packbot and Qinetiq’s

Talon and Dragon Runner.

After hiding the Scorpion behind a shroud at a recent Army

conference, Bielat and engineers at Endeavor showed it for

the first time publicly to The Associated Press in November.

Using a touchscreen controller that taps into the machine’s

multiple cameras, an engineer navigated it through tunnels,

over a playground-like structure and through an icy pool of

water, and used its grabber to pick up objects.

It’s a smaller version of its predecessor, the Packbot, which

was first used by U.S. troops in Afghanistan in 2002 and later

became one of soldiers’ essential tools for safely disabling

improvised explosives in Iraq. Bielat said the newer Scorpion

and Centaur robots are designed to be easier for the average

soldier to use quickly without advanced technical training.

“Their primary job is to be a rifle squad member,” Bielat said.

“They don’t have time to mess with the robot. They’re going

to demand greater levels of autonomy.”

It will be a while, however, before any of these robots become

fully autonomous. The Defense Department is cautious

about developing battlefield machines that make their own

decisions. That sets the U.S. apart from efforts by China and

Russia to design artificially intelligent warfighting arsenals.

A November report from the Congressional Research Service

said that despite the Pentagon’s “insistence” that a human

must always be in the loop, the military could soon feel compelled

to develop fully autonomous systems if rivals do the

same. Or, as with drones, humans will still pull the trigger,

but a far-away robot will lob the bombs.

FLIR Announces Two Bluetooth

Connected Moisture Meters for



announced two moisture meters with Bluetooth® wireless

connectivity: The FLIR MR59 Ball Probe Moisture Meter and

the FLIR MR55 Pin Moisture Meter. These accurate, easy-touse

inspection tools offer moisture remediation, pest control,

home or building inspection, and floor installation professionals

the ability to read moisture measurements from a

mobile device.

The MR59 is a pinless moisture meter, unique for its ball

probe sensor, which helps users cover larger areas in a shorter

time. The ball probe makes it easy to measure in corners,

over uneven surfaces, and around baseboards without leaving

marks. The MR59 can help detect moisture below a surface

when there is no visible presence, enabling professionals

to determine the moisture migration path from the source.








Wireless connectivity enables remediation, home inspection, pest control

and other pros to view moisture readings from a mobile device.

The MR55 is a pin meter with a built-in library of 11 material

groups: wood, drywall, concrete, brick, and other building

materials. The user can tune the meter to the most appropriate

test material to improve measurement accuracy. Professionals

can also access a material group reference document

from FLIR.com by using a smartphone device to scan a QR

code on the back of the meter.

Both the MR59 and MR55 were designed for professionals to

improve work efficiency, inspect any location with ease, and

access the most accurate moisture readings possible. Wireless

connectivity in both devices offers a convenient way to

view data from a mobile device with the FLIR Tools® Mobile

App. This is useful when the meter’s display is out of view,

such as when taking measurements on the ceiling or within

a cabinet.

The new moisture meters will be available for purchase in

the United States beginning in mid-September through FLIR

distributors. For more information, visit FLIR.com.

Computer Scientists Study Security

Threats to Smart Homes By Tamara Dietrich

And you’re none the wiser — until you get home and discover

your home’s been hacked. And burgled.

This is just one scenario demonstrating one of many inherent

flaws that computer scientists at the College of William and

Mary discovered in internet-connected smart home devices

during tests they conducted over the summer.

This particular flaw allows hackers to attack a smart home’s

low-security device — a light switch or thermostat, for instance

— and use that access to attack a high-security device

they could not otherwise access.

It’s one example of what’s called lateral privilege escalation,

and experts warn that such smart home hacks are easier than

you might think. They can lead to all kinds of potential mischief,

if not outright harm, from switching off your security

system to cranking up your smart oven until it overheats and

burns the house down.

“The possibilities are limitless,” said Adwait Nadkarni, lead

investigator and assistant professor of computer science.

“There are so many devices in the home that affect your

security, affect the integrity of your home.”

Experts say that in just two years there will be 20 billion

smart home products in use.

William & Mary computer science associate professors Adwait Nadkarni and

Denys Poshyvanyk and their students have identified security vulnerabilities

in smart home devices. Weaknesses in the security of a Web-enabled light

bulb could give hackers access to Web-enabled cameras and security devices,

allowing them to be disabled. (Rob Ostermaier/The Daily Press via AP)

WILLIAMSBURG, Va. (AP) — Say you’re on your laptop at

Starbucks, minding your own business, when an acquaintance

of yours across the room isn’t minding his.

Unbeknownst to you, he’s using the same store Wi-Fi as you

to conduct a virtual invasion of your smart home: accessing

your light switch app and using it to disable your home’s

security camera so real thieves can break in — or walk in, if

he’s disabling the smart lock, too.

“You can imagine the possible combinations of these kinds

of attacks will obviously increase as we’ll have more interconnected

devices,” said associate professor Denys Poshyvanyk.

“At this point, it’s hard for us to imagine what else people

will do.”

Nadkarni and Poshyvanyk co-authored a paper on their work

that they’ll present at the 9th annual ACM Conference on

Data and Application Security and Privacy in Dallas in March.

Student co-authors include Kaushal Kafle and Sunil Manandhar

and post-doctoral fellow Kevin Moran.

In the paper, they lay out the potential misuses of the computer

routines or portions of code that control smart home

products and offer 10 key findings with “serious security


“The diversity of these products is staggering,” the paper

states, “ranging from small physical devices with embedded

computers such as smart locks and light bulbs to full-fledged

appliances such as refrigerators and HVAC systems.”

And the risks, it states, can be rather alarming.

“Because many of these products are tied to the user’s security

or privacy (e.g., door locks, cameras), it is important to

understand the attack surface of such devices and platforms

in order build practical defenses without sacrificing utility.”

For their research, Nadkarni and Poshyvanyk focused on

two of the most popular smart home platforms — Google

(Continued on page 56)

54 | Chief Engineer

Volume 84 · Number 2 | 55


Nest and Philips Hue — that implement home automation


Routines are the interactions between smart home devices

and the apps that control them. They are becoming the heart

of seamless home automation.

According to the paper, there are two broad categories of

routines: one that allows users to “chain together” a variety

of devices using a third-party app interface, and one

that uses a “centralized data store” as a sort of switchboard

where devices and apps can communicate with each other

over the internet.

Both are intended to make smart home automation more

seamless for the user, and both were found to be vulnerable,

giving hackers the ability to attack all the internet-connected

devices in the home.

For the centralized data store platform, for instance, when

you use your mobile app to communicate with a low-security

device — say, a light switch — the device accesses your smart

home using an authorization token.

“Anybody can steal that access token,” Nadkarni said, and

use it to, say, make your smart home think you’re inside and

turn off the security camera.

The scientists insist it’s not that hard.

“You don’t need any specialized education,” said Poshyvanyk.

‘You just need to know how to run certain programs.

Even a high schooler could do that.”

They blame the vulnerabilities on consumer demand and the

headlong rush to meet it.

“Manufacturers race to release these systems without having

a good understanding of how they will be used in the wild,”

Poshyvanyk said.

After the researchers identified the security flaws, they contacted

platform vendors Google and Philips and app developer

and manufacturer TP Link to report what they found.

TP Link fixed the flaw in its latest Kasa Switch light dimmer

app, which prevents the type of theoretical lateral attack

outlined earlier. Philips is expected to roll out a fix to its platform

and Google is working to address vulnerabilities.

But the issue is bigger than one company — it’s the industry

overall that needs to get smarter.

“We’re basically arguing that we need a systemic effort in

terms of properly designing these systems with security in

mind,” Poshyvanyk said.

EVAPCO Water Saver Provides

Pre-treatment for Evaporative Cooling


EVAPCO Water Systems has introduced the Water Saver, a

device that substantially reduces water use for evaporative

cooling equipment — whether new, or as a retrofit.

Just recently, an Indiana school with a 1,200-ton HVAC system

reduced water consumption by 1.5 million gallons/year

with the technology.

Water Saver is a capacitive deionization pre-treatment

system to improve the efficiency of heat transfer and water

efficiency for evaporative cooling systems. The capacitive

deionization technology reduces dissolved ion concentrations

to lower makeup water conductivity prior to use in evaporative

cooling systems. Dissolved ions are removed from makeup

water as they are attracted to the charged capacitors.

Water Saver improves water efficiency by increasing operating

cycles of concentration; this reduces blowdown and the

use of treatment chemicals. Water Saver lowers cost of ownership,

provides a 75-90 percent recovery rate, and improves

a facility’s LEED rating. The technology is available in nine

different configurations.

St. Cloud Wastewater Plant Fueled by

Beer, Byproducts By Anna Haecherl | Saint Cloud Times

ST. CLOUD, Minn. (AP) — Whenever you dump something

down the drain, it goes to the city of St. Cloud’s NEW (Nutrients,

Energy and Water) Recovery Facility, where nutrients

are recovered, waste is treated, and clean water is sent back

into the environment.

But large-scale beverage producers — who have high-sugar

waste filled with potential energy — get special treatment

when it comes to the byproducts created at their facilities.

“We can treat it in a different manner that uses a lot less

electricity, and that we can use to make a fuel,” said Pat

Shea, public services director for the city.

Beverage producers have been bringing what Shea calls

high-strength byproducts to the plant for two years, the

Saint Cloud Times reported. For example, Shea said, a beverage

company or brewery will brew a batch of product, and

once it’s done, the company will clean its production lines

and flush everything out to prepare equipment for the next


That first rinse will still have product in it, Shea said, and

producers can either put it down the drain, or collect it and

bring it to the NEW Recovery Facility.

Shea said the facility has arrangements with Beaver Island

Brewing, Viking Coca-Cola, Cold Spring Brewing and other

local producers.

“Anything we can do to reclaim this product, recover energy

and use it to run the facility, the more efficient we are,” Shea


High-strength byproducts — like expired soda or beer, residue

left over from the brewing process, or a batch of product

that just didn’t turn out right — are put into anaerobic

digesters along with municipal solids from wastewater — like

A large engine runs on biogas at the Wastewater Treatment Facility in St.

Cloud, Minn. Whenever you dump something down the drain, it goes to

the city of St. Cloud’s NEW (Nutrients, Energy and Water) Recovery Facility,

where nutrients are recovered, waste is treated, and clean water is sent

back into the environment. (Dave Schwarz/St. Cloud Times via AP)

human waste, food waste, and solid residue from cleaning

processes — to produce methane gas.

“We take that high-strength waste and we put it into an

anaerobic conditions, meaning without oxygen,” Shea said.

“Then micro organisms that are in those digesters ... will

consume that material for their respiration. It’s a biological

process, and, as they use it for their processes, they create

methane gas.”

The gas is used to power an onsite generator or run boilers

that heat the digesters converting the byproducts into


It’s a win-win, Shea said. Instead of dumping the waste and

using more energy to have it treated at the plant, the byproducts

are being used to power the NEW Recovery Facility.

At Beaver Island Brewing, co-founder Nick Barth said waste

wasn’t such a big issue when they first started at their downtown

brewery. But when they opened their new facility in

May 2017 near St. Cloud Regional Airport and started brewing

at a scale four or five times greater, the decision to bring

byproducts to the NEW Recovery Facility instead of putting

them down the drain was an easy one.

“That’s cool because we’re making energy for the city,” Barth

said. “But what’s even cooler is that we’re drastically reducing

our carbon footprint.”

Barth said the brewery captures and harvests its yeast slurry

and trub — a sugary substance and hop remnants left over

after the brewing — to bring to the NEW Recovery Facility.

“It almost looks like a cream-of-wheat-meets-gelatin (substance)

if I could describe it as anything,” Barth said of the

yeast slurry. “Now instead of sending things down the drain

and having them have to be processed at the wastewater

treatment facility ... we’re bypassing that entire process and

they’re making energy from it.”

About a year and a half ago, Barth said Beaver Island brewed

a batch of beer that just didn’t come out as expected.

“There wasn’t anything technically wrong with it,” Barth

said, but it just didn’t smell and taste exactly like what he

was looking for.

So instead of dumping it down the drain, Beaver Island loaded

up the beer and brought it to the NEW Recovery Facility.

“Pat probably loves when we have a beer go in the wrong

direction, because it generates a lot of energy for them,”

Barth said with a laugh. “But for us, we want to do it as little

as possible.”

It takes about 5.7 million killowatt-hours to power the NEW

Recover Facility each year, according to Assistant Public

Utilities Director Tracy Hodel. In 2018, the facility produced

roughly 85 percent of its energy demand onsite through

solar and methane conversion.

Hodel said 7 percent of that 85 percent of needed energy

that is produced onsite comes from solar arrays at the

facility. The rest (about 80 percent of the plant’s total energy

demand) comes from the methane produced in the facility’s

anaerobic digesters.

“There’s still some (power) that we’re buying,” Hodel said,

but there are plans to add a second generator and have the

facility running completely on energy produced on site by

the end of 2020.

“With adding an additional generator, we will be able to

produce exactly, if not a little bit more, of our total demand.

We’re looking at adding a second generator... and we’re also

looking at adding more solar arrays onsite,” Hodel said.

The second generator could be installed as early as fall of

2019, Hodel said, but the facility expects to have it up and

running by spring of 2020.

Mathematical Probability

Every Friday afternoon, a mathematician goes down to the

bar, sits in the second-to-last seat, turns to the last seat, which

is empty, and asks a girl who isn’t there if he can buy her a



The bartender, who is used to weird university types, always

shrugs but keeps quiet. But when Valentine’s Day arrives, and

the mathematician makes a particularly heart-wrenching plea

into empty space, curiosity gets the better of the bartender,

and he says, “I apologize for my stupid questions, but surely

you know there is NEVER a woman sitting in that last stool.

Why do you persist in asking out empty space?”

The mathematician replies, “Well, according to quantum

physics, empty space is never truly empty. Virtual particles

come into existence and vanish all the time. You never know

when the proper wave function will collapse and a girl might

suddenly appear there.”

The bartender raises his eyebrows. “Really? Interesting. But

couldn’t you just ask one of the girls who comes here every

Friday if you could buy HER a drink? Never know — she

might say yes.”
