In Brief<br />
Southern Indiana City Plans Solar Farm<br />
to Power Sewage Plant<br />
BOONVILLE, Ind. (AP) — A southern Indiana city is<br />
aiming to hold down future increases in sewer bills by<br />
building a 4-acre solar farm.<br />
Boonville officials are moving ahead with an estimated<br />
$1.7 million project for the field of nearly 2,000 solar<br />
panels to power its new sewage treatment plant.<br />
The city expects to sell excess electricity that’s generated<br />
to the utility company Vectren. Projections are that<br />
the city will save about $17,000 a month or $6 million<br />
over the next 30 years.<br />
Mayor Charles Wyatt says he’s glad the city about 15<br />
miles northeast of Evansville can use green energy to<br />
reduce expenses for the sewage plant.<br />
Fermi Two Nuclear Plant is Back Online<br />
Following Repairs<br />
FRENCHTOWN TOWNSHIP, Mich. (AP) — A nuclear<br />
power plant in southeastern Michigan is back online<br />
after being shut down last month for repairs.<br />
The Monroe News reports DTE Energy’s Fermi 2 plant<br />
in Monroe County was synchronized to the electrical<br />
grid on Jan. 1.<br />
DTE Energy spokesman Stephen Tait says the plant<br />
“was maintained in a safe, stable condition throughout<br />
the outage.” The plant was taken offline Dec. 6 as<br />
operators looked into an electrical issue on the plant’s<br />
main generator, which is on the non-nuclear side of<br />
the plant. The issue was traced to a ground fault.<br />
The Detroit-based utility’s plant is located along Lake<br />
Erie in Frenchtown Township, near Michigan’s border<br />
with Ohio.<br />
Rock Falls Planners Object to Proposed<br />
Community Solar Farm<br />
ROCK FALLS, Ill. (AP) — Planning officials in a northwestern<br />
Illinois community are opposing a proposed<br />
community solar farm just outside its city limits.<br />
Sauk Valley Media reports that the Rock Falls Plan<br />
Commission recommended that the city object to the<br />
project, saying it is incompatible with comprehensive<br />
plans of the city and Whiteside County.<br />
The proposed project site is in an agricultural area. The<br />
city contends the site should continue to be used for<br />
farming until it can be developed for more traditional<br />
commercial purposes.<br />
Minnetonka, Minnesota-based Sunrise Energy Ventures<br />
has applied to the county for a special-use permit for<br />
the project. Rock Falls has a say in the matter because<br />
the site is within a 1.5-mile radius of its borders.<br />
Rock Falls is about 115 miles (185 kilometers) west of<br />
Chicago.<br />
Michigan’s $52M for Lock May Speed<br />
Construction, Save Money<br />
LANSING, Mich. (AP) — Michigan’s commitment of<br />
up to $52 million toward construction of a new Great<br />
Lakes shipping lock could accelerate the project’s completion<br />
by a year and save taxpayers $30 million.<br />
Gov. Rick Snyder and the U.S. Army Corps of Engineers<br />
released the figures Dec. 26 while announcing a memorandum<br />
of agreement.<br />
Michigan’s funds will be used to pay for design work<br />
and a portion of a channel deepening project that will<br />
be an important step toward building a second largesized<br />
lock at Sault Ste. Marie to accommodate freighters<br />
that haul iron ore and other bulk commodities. The<br />
federal government is spending $32 million on the<br />
channel deepening.<br />
Congress has authorized funding for the second large<br />
Soo Lock but must appropriate funds over numerous<br />
years to pay for the $1 billion project.<br />
Cleanup Set for 200,000 Waste Tires<br />
Left at Indiana Business<br />
ANDERSON, Ind. (AP) — State environmental officials<br />
are stepping in to clean up nearly 200,000 shredded<br />
tires left at a former central Indiana recycling business.<br />
The Indiana Department of Environmental Management<br />
estimates cleaning up the Green Tire Reclamation<br />
site in Anderson could cost up to $262,000 and<br />
will take about a year. The (Anderson) Herald-Bulletin<br />
reports the tires have been cut into 2-inch chunks and<br />
stacked in massive piles on the property that appears<br />
abandoned.<br />
The business opened in 2012 with permission to store<br />
5,000 waste tires it would shred for uses such as being<br />
burned in power plants or as construction fill. But business<br />
owner Dan McKenzie said in 2014 he hadn’t been<br />
able to find buyers for the shredded tires. McKenzie<br />
didn’t return phone calls to comment on the cleanup.<br />
3 Firms Eye Building Wind Energy Turbines<br />
off New Jersey<br />
ATLANTIC CITY, N.J. (AP) — At least three firms are interested<br />
in building offshore wind energy projects off<br />
the coast of New Jersey.<br />
The state Board of Public Utilities says it received three<br />
bids Friday, Dec. 28, from firms interested in building<br />
wind projects, but it wouldn’t identify any of them.<br />
A Danish wind company, Orsted, said it had submitted<br />
one of them.<br />
The state is seeking companies to build projects that<br />
would generate at least 1,100 megawatts of electricity.<br />
Orsted estimates that amount could power more than<br />
a half-million homes.<br />
Another company, Atlantic Shores Offshore Wind, says<br />
it’s interested in developing a project that could provide<br />
up to 2,500 megawatts.<br />
It was not immediately known whether that firm,<br />
which is a joint venture between Shell and EDF Renewables<br />
North America, has formally applied.<br />

DTE Energy Agrees to $840,000 Fine in<br />
Shut-Off Snafu<br />
DETROIT (AP) — A mess over billings and improper<br />
shutoffs has led to an $840,000 fine for DTE Energy.<br />
State regulators approved the settlement early last<br />
month. Sally Talberg of the Michigan Public Service<br />
Commission says the commission has “great concern<br />
when utilities violated consumer protection rules.”<br />
The investigation began a year ago, months after DTE<br />
began using a new billing system. The commission<br />
received complaints that power was being improperly<br />
shut off. More than 4,000 customers did not receive a<br />
proper shut-off notice for nonpayment.<br />
DTE has agreed to refund all deposits and reconnection<br />
fees. The utility also will be audited over its shutoff<br />
procedures until 2<strong>02</strong>0.<br />
A group known as the Residential Customer Group<br />
watched the case and objected to the settlement. Michelle<br />
Rison says the fine isn’t high enough, especially<br />
when some shut-offs occurred during cold weather.<br />
Illinois EPA Offers Grants for Wastewater<br />
Efficiency<br />
SPRINGFIELD, Ill. (AP) — The Illinois Environmental Protection<br />
Agency is offering grants to public wastewater<br />
treatment plants to improve energy efficiency.<br />
The agency has announced $3 million in grant funding.<br />
Grants ranging from $5,000 to $1.5 million will<br />
reduce energy consumption at treatment plants.<br />
EPA Director Alec Messina says the department has<br />
worked with 15 Illinois municipalities for no-cost<br />
efficiency assessments. The grant program uses U.S.<br />
Department of Energy funds to upgrade plants where<br />
the most cost savings will be.<br />
Applications for the grant are available online from<br />
the EPA. Applications are due by Feb. 12, <strong>2019</strong>.<br />
The applications will be ranked according to energy<br />
savings per dollar invested, energy rate paid by the<br />
facility and the energy cost to treat one million gallons<br />
of water at the plant.<br />
Renovation to Preserve Courthouse<br />
Once Visited by Lincoln<br />
THEBES, Ill. (AP) — A historic southern Illinois courthouse<br />
once visited by Abraham Lincoln is getting an<br />
$83,000 renovation with help from a private donor.<br />
The Old Thebes Courthouse overlooking the Mississippi<br />
River was built in the 1840s and is listed on the National<br />
Register of Historic Places. Dred Scott, the slave<br />
whose fight for freedom became a landmark Supreme<br />
Court ruling, was held in its jail.<br />
The Southern Illinoisan reports the structure fell into<br />
disrepair after the county seat moved in 1860.<br />
Goins says it “will look like new” when it’s done this<br />
summer.<br />

Texas Training for Wind Power Jobs<br />
Literally Has Ups, Downs<br />
By Andrea Leinfelder | Houston Chronicle<br />
In addition to studying hydraulics, welding and electrical<br />
theories during the seven-month program, MIAT students<br />
must learn to safely climb the roughly 300-foot towers and<br />
to rescue their colleagues should something go wrong.<br />
“That way, when they go out in the field, I’ve personally<br />
verified that they can actively protect themselves at height,”<br />
said David Moriconi, lead wind instructor at MIAT.<br />
So Snoddy attached his harness to a cable in the center of<br />
the ladder. He climbed to the top and transitioned to a platform,<br />
which involved unclipping from the cable at his chest<br />
and then clipping a dual-shock-absorbing lanyard to his back.<br />
He then attached a self-retracting line — a yo-yo-like<br />
contraption that would catch Snoddy should he fall — and<br />
unclipped the shock-absorbing lanyard.<br />
All of that had to be done before setting to work, with hand<br />
signals from below indicating that he needed to lift or lower<br />
a set of tools. And then Snoddy climbed back down the ladder<br />
in an equally safe fashion.<br />
He passed with flying colors.<br />
The test earned students a climb and rescue certification<br />
required by many employers.<br />
Tony Robinette, field operations manager for renewable<br />
energy and construction at the staffing firm System One, emphasized<br />
the importance of this climb test, saying the most<br />
catastrophic injuries often come from climbing.<br />
He also applauded MIAT, saying the students are well prepared<br />
when they graduate. It helps that MIAT has a longer<br />
training period than some other programs.<br />
“They definitely come out and hit the ground running,” he<br />
said.<br />
And to make the training more fun, MIAT held a competition<br />
on the eve of its official climb test. Moriconi clocked how<br />
quickly students could climb the ladder five times. That’s<br />
roughly the height of a single section on a wind turbine tower<br />
— and most towers have four sections.<br />
The fastest time was 1 minute, 30 seconds. The slowest time<br />
was around 4 minutes, 30 seconds.<br />
Snoddy came in second place at 1 minute, 56 seconds. Good,<br />
but not entirely satisfying.<br />
“I’m an ex-athlete,” he said, “so I wish I came in first.”<br />
MIAT College of Technology Wind Turbine Instructor David Moriconi, third from right, gives Anthony Snoddy, second from right, instructions before a<br />
ladder exercise in Houston. MIAT College of Technology has a seven-month wind power technician career training program. (Steve Gonzales/Houston<br />
Chronicle via AP)<br />
HOUSTON (AP) — Anthony Snoddy was first to climb the 18-<br />
foot ladder.<br />
The Houston Chronicle reports as the kid who found the tallest<br />
trees and front-flipped off buildings, Snoddy, 36, wasn’t<br />
worried about the height. He knew it would be part of his<br />
job maintaining and repairing wind turbines.<br />
“Just make sure you do everything correctly,” Snoddy told<br />
himself as he approached the ladder.<br />
In 2018, the MIAT campus in north Houston saw a 60 percent<br />
enrollment increase in its wind power technician program,<br />
which averaged 25 to 30 students. The U.S. Bureau of Labor<br />
Statistics expects that the field will grow to 11,400 wind turbine<br />
technicians in 2<strong>02</strong>6, up from 5,800 in 2016.<br />
Instead, he was focused on the safety clamps and procedures<br />
for climbing the ladder. These weren’t part of his riskier<br />

Electric Garage Heaters for a Warm<br />
Workshop By Jim Herring<br />
Most garages are not connected to central heating, making<br />
them a large cold spot in most home heating systems. When<br />
winter comes, an unheated garage can be a cold and unappealing<br />
place for home maintenance, tinkering and other<br />
hobbies.<br />
One way to keep a garage workspace toasty even in the<br />
harshest winters is choosing a top-notch electric garage heater.<br />
Electric heaters offer several benefits over other heating<br />
systems — they don’t require venting like gas heaters and<br />
can be more cost-effective.<br />
Electric Heater Benefits<br />
One factor to consider when heating a garage is safety. Electric<br />
heaters do not pose the same risks as propane or natural<br />
gas heaters. Along with a car, truck or other gas-powered<br />
vehicles, people also store gas, oil and other flammables in a<br />
garage. Because there are no open flames or exhaust fumes<br />
with electric heaters, they’re safer to use around gas vehicles<br />
and lawn tools.<br />
Electric heaters also offer efficiencies that other heaters do<br />
not. With an electric garage heater, every bit of electricity<br />
used is converted into heat. With propane, on the other<br />
hand, only 80 percent of its fuel is used for heat while the<br />
other 20 percent is lost by-products. That fuel loss translates<br />
into inefficiency and can mean higher costs for homeowners.<br />
Electric garage heaters also provide the flexibility to provide<br />
warmth without taking up floor space or creating a tripping<br />
hazard. They can be mounted on the wall or ceiling, and angled<br />
to push warm air horizontally, vertically or in any other<br />
desired direction. These installation and airflow options are<br />
much harder to achieve with a gas garage heater.<br />
Choosing the Appropriate Heater<br />
Whether using the garage for random hobbies or a regular<br />
hangout, there are several electric heating options to choose<br />
from including radiant electric, portable heaters and fanforced<br />
units:<br />
• Radiant electric heaters are designed to target a specific<br />
area with heat, typically using infrared technology to heat<br />
the objects in the room instead of the air.<br />
• Portable heaters are easy to move around the garage, targeting<br />
heat to the necessary spots where one is working.<br />
• Fan-forced heaters move warm air throughout an entire<br />
garage for balanced, all-over heating.<br />
Consider how the heater will be best used in your garage<br />
before making a selection.<br />
Garage Heater Installation Tips<br />
How best to install an electric heater varies depending on<br />
the type. Some models may need to be wired by an electrician<br />
or trained professional, while others are portable and<br />
can be easily mounted and simply plugged in.<br />
Before hooking anything up, be sure to check the voltage<br />
requirements. With a plug-in 120V electric garage heater,<br />
Electric garage heat offers advantages that gas heated garages don’t —<br />
ventilation isn’t a problem, and costs can be lower than for gas heating<br />
systems.<br />
for example, all that’s needed is an outlet. An electric heater<br />
that runs at a voltage higher than 120, however, will need to<br />
be wired in. This will require some electrical work.<br />
Also, make sure that the model of heater is sized appropriately<br />
for the space. To ensure a heater is generating enough<br />

High-Speed Rail From St. Louis to<br />
Chicago Faces More Delays<br />
ST. LOUIS (AP) — Railway commuters traveling between St.<br />
Louis and Chicago have yet to see faster rail journeys, despite<br />
most of the Amtrak corridor’s $1.95 billon upgrade concluding<br />
a year ago.<br />
Delays in installing and testing new GPS-related safety technology<br />
kept Amtrak trains from hitting high speeds of 90<br />
mph during 2018, as the Illinois Department of Transportation<br />
originally projected, the St. Louis Post-Dispatch reported.<br />
Trains are not allowed to travel faster than 79-mph on<br />
the route.<br />
The Illinois agency projects that 90-mph speeds will be in<br />
place for Amtrak by the summer from Alton to south of<br />
Springfield. Most of the remainder of the route is expected<br />
to implement 90-mph speeds by the end of this year.<br />
The top speeds will be used only in the more open expanses<br />
of the route outside the St. Louis and Chicago metropolitan<br />
areas.<br />
Contractors and crews from Union Pacific Railroad work both above and<br />
below the Wood River Creek railroad bridge Tuesday, May 16, 2017, just<br />
east of the Homer Adams Parkway extension railroad bridge in Alton, Ill.<br />
Workers are replacing the old steel bridge’s deck and working in the creek<br />
below. Pre-assembled sections of concrete railroad ties and track are being<br />
pulled into place to run across the bridge when the deck is finished. The<br />
work is for the new high-speed rail line between Chicago and St. Louis<br />
which is scheduled to be in service by this fall. (John Badman/The Telegraph<br />
via AP)<br />
The Illinois Transportation Department had previously said<br />
speeds of 110 mph would be reached by <strong>2019</strong>, but the agency<br />
has stopped offering predictions on when that will happen.<br />
The 110-mph speed would shave about an hour off the<br />
typical 5½-hour Amtrak trip between St. Louis and Chicago.<br />
The project was funded in 2010, largely by federal economic<br />
stimulus dollars allotted under then-President Barack Obama.<br />
Jessie Decker, an Illinois Transportation Department spokeswoman,<br />
said in an email to the St. Louis Dispatch that an<br />
early version of the safety technology, named positive train<br />
control, is in service on most of the 215-mile stretch of the<br />
284-mile corridor owned by Union Pacific.<br />
Decker noted that Amtrak is upgrading software on its trains<br />
to communicate with the positive train control system, which<br />
helps monitor trains’ position and speed. If a train engineer<br />
were to fail to respond to an upcoming signal, the locomotive<br />
would take over control and slow or stop a train to avoid<br />
a crash.<br />

Missourians Want Action Over Too-High<br />
Illinois Levee By Jim Salter<br />
action if the Sny Island Levee District in Illinois fails to reduce<br />
its levee height. FEMA didn’t respond to the alliance but told<br />
The Associated Press it is working to resolve the issue.<br />
Missouri residents have complained for years that the Sny<br />
has been built several feet too high in some spots. The 60-<br />
mile (96.5-kilometer) system is north of St. Louis and protects<br />
roughly 115,000 acres of fertile Illinois farmland.<br />
The upper Mississippi River is lined with levees that protect<br />
towns, businesses and hundreds of thousands of acres of<br />
agricultural land. But in times of flooding, water that would<br />
naturally flow over a flood plain is boxed out and forced<br />
elsewhere. Such redirecting of floodwater is especially<br />
concerning given the increasing volatility of the river, which<br />
has seen damaging flooding far more frequently in recent<br />
decades.<br />
Crews check out the 54 mile long Sny Levee that protects 125,000 acres of<br />
prime farmland as the Mississippi River continues to rise south of Quincy,<br />
Ill. Some Missouri landowners as well as environmentalists are urging the<br />
Federal Emergency Management Agency to take sanctions against the Sny<br />
Island Levee District in Illinois for raising its levee to unauthorized heights.<br />

ST. LOUIS (AP) — Missouri landowners and environmentalists<br />
are urging a federal agency to sanction a levee district on the<br />
Illinois side of the Mississippi River, arguing that the earthen<br />
barrier has been built above its authorized height, worsening<br />
flooding for its neighbors.<br />
Great Rivers Habitat Alliance, a river conservation organization<br />
based in St. Louis, sent a letter to the Federal Emergency<br />
Management Agency in October urging the agency to take<br />

NEWS<br />
“These levees have a maximum height because in some<br />
instances they’re supposed to be topped,” said David Stokes,<br />
executive director of the Great Rivers Habitat Alliance. “You<br />
don’t want to sacrifice a city to keep the farmland dry.”<br />
A study by the Army Corps of Engineers in 2017 found that<br />
40 percent of the 205 miles (330 kilometers) of levees from<br />
central Iowa to St. Louis were built above their authorized<br />
heights. Missouri, Iowa and Illinois all had levees in violation.<br />
The Sny is the longest of those systems and, some Missouri<br />
residents say, the biggest violator. The Corps has said the Sny<br />
is up to 4 feet (1.2 meters) above authorized levels in some<br />
spots.<br />
In January 2016, FEMA’s Mitigation Division asked leaders of<br />
the three Illinois counties responsible for the Sny — Pike, Calhoun<br />
and Adams counties — to show permits proving that<br />
raising the levee was authorized.<br />
Three years later, it remains unclear if any permits were<br />
provided.<br />
Mike Reed, superintendent of the Sny district, said in an<br />
email to The Associated Press that the levee district is working<br />
with FEMA “to clear up questions that may remain as to<br />
the authorized levee elevation.”<br />
FEMA spokeswoman Cassie Ringsdorf said in an email that<br />
the agency “has been working with the state of Illinois and<br />
the U.S. Army Corps of Engineers to determine the best<br />
course of action to address those issues.”<br />
In the Oct. 8 letter to FEMA Mitigation Division Director<br />
Mary Beth Caruso, Stokes urged FEMA to cut off availability<br />
of insurance through the National Flood Insurance Program<br />
to Illinois property owners behind the Sny unless the levee<br />
height is reduced.<br />
“It’s time to crack down,” he said.<br />
Local farmer Nancy Guyton agreed. Guyton and her husband<br />
grow corn and soybeans on 1,500 acres in the flood plain of<br />
Pike County, Missouri, directly across from the Sny. She said<br />
the too-tall Illinois levee means more significant damage to<br />
the family farm as the murky and often-toxic water sticks<br />
around longer during a flood.<br />
“It’s just a real mess and FEMA can do something about it,”<br />
Guyton said. “They’re dragging their heels. They should have<br />
taken care of this matter several years ago.”<br />
Maryland Board Votes Against Natural<br />
Gas Pipeline Project By Brian Witte<br />
ANNAPOLIS, Md. (AP) — A board of<br />
high-ranking Maryland officials on Wednesday,<br />
Jan. 2, rejected a proposed pipeline<br />
across the western part of the state that<br />
would carry natural gas produced in Pennsylvania<br />
to West Virginia.<br />
The Board of Public Works voted 3-0 against<br />
an easement for TransCanada’s pipeline. It<br />
would run under the Potomac River near<br />
Hanover, Md., and extend about 3 miles<br />
(4.83 kilometers) from Columbia Gas’ network<br />
in Pennsylvania to Mountaineer Gas’<br />
distribution system in West Virginia.<br />
Comptroller Peter Franchot, a Democrat, cited<br />
testimony that the pipeline could bring<br />
Maryland environmental problems without<br />
economic benefits. The board also includes<br />
Maryland Gov. Larry Hogan, a Republican,<br />
and Treasurer Nancy Kopp, a Democrat.<br />
Environmentalists and residents have been<br />
vocal in opposing the pipeline.<br />

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<br />
Gov. Larry Hogan to reject the project. The bottom line reads: “No Potomac Pipeline.” A board of high-ranking Maryland officials rejected the pipeline<br />
Wednesday, Jan. 2, <strong>2019</strong>, that would carry natural gas produced in Pennsylvania to West Virginia. (AP Photo/Brian Witte, File)<br />
noted that Maryland approved a law, which Hogan signed in<br />
2017, to ban the hydraulic fracturing drilling process known<br />
as fracking in Maryland. The process is used to extract natural<br />
gas. Maryland was the first state where a legislature voted<br />
to bar the practice that actually has natural gas reserves.<br />
“Given that Maryland has banned fracking, it defies our<br />
state’s existing energy policy to bring the same public health<br />
risks to our residents by way of a pipeline,” the letter said.<br />
“Moreover, enabling fossil fuel production runs counter to<br />
our state’s goals of increasing renewable energy production.”<br />
The letter, which was sent the week of the meeting, also noted<br />
that the pipeline would affect at least 10 wetlands and 19<br />
streams, in addition to the Potomac River.<br />
While the board delayed a vote on the easement at its last<br />
meeting, Hogan said the unanimous vote would have happened<br />
without the letter from lawmakers.<br />
“It had nothing to do with any letter from the legislature,”<br />
Hogan said at the Jan. 2 board meeting.<br />
Anne Havemann, an attorney for Chesapeake Climate Action<br />
Network, said she hopes the board’s vote marks an end to<br />
the proposal.<br />
“We’ll see if (the Federal Energy Regulatory Commission)<br />
gets involved or the courts get involved, but for now it’s a<br />
welcome delay and we hope a permanent end to this pipeline,”<br />
Havemann said shortly after the vote.<br />
DODGEVILLE, Wis. (AP) — Residents in a rural Wisconsin<br />
county are split over a Chicago developer’s plan to work<br />
with two Wisconsin utilities to build a solar farm that would<br />
include more than 1 million solar panels.<br />
The Wisconsin State Journal reports that the Badger Hollow<br />
Solar Farm proposed by Invenergy would cover 2,700 acres in<br />
Iowa County and could power more than 70,000 homes. The<br />
project is seeking a permit from the Wisconsin Public Service<br />
Commission.<br />
Ken Wunderlin, a southwest Wisconsin farmer, said he<br />
agreed to have part of the solar farm on his land because<br />
it’s a good financial move. He believes it’s also a chance to<br />
get involved in a more environmentally friendly source of<br />
energy.<br />
“I’m a firm believer in the science on global warming,” he<br />
said. “We need to be taking steps to get away from coalfired<br />
power. This is my small opportunity to be a participant.”<br />
Renewable energy advocates have hailed it as a way for utilities<br />
to produce low-cost, clean energy within the state while<br />
providing some $1.8 million a year in rents for hard-pressed<br />
sharecroppers like Wunderlin.<br />
“We think of it as a complete win for the state of Wisconsin,”<br />
said Michael Vickerman, policy director for Renew<br />
Wisconsin. “We’re talking about renewable generation<br />
completely located within the state of Wisconsin. It is clean.<br />
It is quiet. It yields a great deal of financial benefits to the<br />
landowners and the surrounding communities.”<br />
But not everyone in Iowa County is welcoming the development.<br />
Richard Jinkins, a southwest farmer who lives just east of<br />
Wunderlin’s land on a 400-acre farm, said he’s worried that<br />
the farm will destroy the area’s scenic beauty, take up valuable<br />
farmland and cause the county’s 23,687 population to<br />
drop.<br />
Jinkins, along with two other nearby farmers, are leading the<br />
charge against the project as it goes through the permitting<br />
process with the Wisconsin Public Service Commission.<br />
“In the best case (it’s) going to make a solar panel wasteland<br />
where nobody’s going to live,” said Jinkins, a computer programmer<br />
who also raises cash crops. “It’s not going to be the<br />
Driftless area. It’s going to be the utility district of southwest<br />
Wisconsin.”<br />

North Dakota Bill Seeks to Discourage<br />
Pipeline Tampering<br />
BISMARCK, N.D. (AP) — A North Dakota legislator wants to<br />
increase the legal consequences for people who tamper with<br />
pipelines and any groups that help them, following a 2016<br />
pipeline protest that shut down oil flow for several hours.<br />
Republican Sen. Janne Myrdal of Edinburg is sponsoring the<br />
bill, The Bismarck Tribune reported.<br />
The legislation would more clearly define that it’s illegal to<br />
damage energy facilities and other critical infrastructure,<br />
such as refineries, electrical power generating facilities or<br />
natural gas processing plants.<br />
It also would increase maximum fines from $10,000 to<br />
$100,000 if an organization is found to have conspired with<br />
individuals who tamper with infrastructure.<br />
The bill wouldn’t prevent the “lawful assembly and peaceful<br />
and orderly petition for the redress of grievances.”<br />
“We worked hard on it to make sure that no First Amendment<br />
rights are trampled on whatsoever in this bill,” Myrdal<br />
said.<br />
Myrdal said the bill was inspired by the October 2016 pipeline<br />
protest involving TransCanada’s Keystone Pipeline, when<br />
activists turned an emergency valve and shut down oil flow.<br />
Seattle resident Michael Eric Foster, who served jail time for<br />
turning the pipeline valve during the protest, said a more<br />
stringent law wouldn’t have stopped him.<br />
“What I did, I did to protect my family because everything<br />
else is failing. I owe it to my family tree and yours to do<br />
whatever we can think of to stop destroying this place for<br />
our kids,” Foster said.<br />
Foster said the bill is an attempt to “silence and intimidate<br />
and harass people who are looking out for the public good.”<br />

Masonry Gives Construction Students<br />
Hands-On Training By Andrew Wind | Waterloo-Cedar Falls Courier<br />
WATERLOO, Iowa (AP) — Students in Wayne Lidtke’s sustainable<br />
construction and design class have learned about house<br />
building by doing it.<br />
They’ve framed walls, hung drywall, installed windows and<br />
doors, and done minimal wiring while building small scale<br />
houses at the Waterloo Career Center. The students will be<br />
working on some other skills, like roofing, in the Waterloo<br />
Community Schools’ program before the semester is over, the<br />
Waterloo-Cedar Falls Courier reported.<br />
Though, the nine high schoolers put down their hammers<br />
and picked up trowels. Iowa Masonry Institute members<br />
taught them lessons on mixing mortar and building a number<br />
of structures with cinder block and brick.<br />
Their task was to construct a pier. The column-like structure<br />
can support a beam in a building, an overhang on an entryway<br />
or have a more decorative use at the end of a driveway.<br />
Students shoveled mortar out of wheelbarrows onto plywood<br />
platforms. They scooped up the substance with their<br />
trowels, depositing it on the edges of a pair of cinder blocks<br />
before adding another layer of blocks.<br />
“You put a lot of mortar there so you have a lot of contact,<br />
just so in a couple years it doesn’t fall apart,” said Hunter<br />
Pierce, a West High School senior.<br />
Chris Busch, overseeing the students’ efforts, emphasized the<br />
importance of getting the right amount of mortar between<br />
the blocks.<br />
“That joint is an integral part of the unit,” noted the Marshalltown-based<br />
Bricklayers & Allied Craftworkers union<br />
training director. Ideally, he said, the mortar level will be<br />
about three-eighths of an inch.<br />
Without the right amount, “it’ll start to lose considerable<br />
integrity,” said Busch. “Three-eighths is kind of that sweet<br />
spot.”<br />

they’re going to veneer it with brick,” he explained.<br />

As one of the students got several blocks high, Busch offered<br />
a bit of advice: “You can use your level to check that, check<br />
for level (horizontally) and plumb (vertically)” to ensure<br />
everything is straight and level.<br />
“It’s fun, it’s something to do,” said West High junior Nathan<br />
Elliott, of learning the skill. “Better than sitting in there on a<br />
computer. I like the hands-on stuff.”<br />
Pierce also likes learning this way and said he would consider<br />
working in construction.<br />
Those are the sorts of responses Busch hopes for from his<br />
training sessions at schools.<br />
“This is basically part of our recruitment,” he said. Students<br />
started with basics like learning how to spread mortar, lay<br />
brick and use a level. They also built a low wall earlier.<br />
Busch doesn’t expect everyone in the class to end up as a<br />
bricklayer. But bringing the program into schools is important<br />
to finding the next generation of workers — and the<br />
amount of time they’ve had at the career center only helps.<br />
“This is great having a whole week in here to present masonry<br />

Reinventing Fire Detection in Industrial<br />
Warehouses<br />
The cost of a fire in a warehouse goes far beyond the loss<br />
of the building and goods. The consequential loss caused by<br />
downtime, operation interruption, business reputation and<br />
goodwill can be significant.<br />
Modern goods also tend to have increased flammability, in<br />
addition to the presence of large amounts of packing materials<br />
such as plastics, cardboard, wooden crates and pallets.<br />
There are various possible ignition sources in warehouses including<br />
smoking, lighting, electrical equipment and heaters.<br />
Although sprinklers are typically installed in warehouses, the<br />
lack of an appropriate early warning smoke detection system<br />
can not only compromise the safety of the facility but also<br />
that of adjacent buildings.<br />
Fortunately, protecting life and inventory is much easier for<br />
even the largest warehouses as aspirating smoke detection<br />
(ASD) technology becomes more widely adopted. The process<br />
draws in air samples through durable piping to detectors and<br />
tests it using sophisticated laser-based technology, imaging,<br />
and photodiodes. Far from new, the core technology<br />
has been used for decades in sensitive applications such as<br />
cleanrooms and data centers where early smoke detection is<br />
critical.<br />
ily diluted. This makes detection difficult for conventional<br />
detection technologies where smoke must build up to certain<br />
levels before the alarm sounds. Furthermore, before sprinklers<br />
are triggered, sufficient heat needs to be generated by<br />
the fire — by which time, it is well underway.<br />
Because of these concerns, traditional spot smoke detectors<br />
are usually considered unsuitable for warehouses with high<br />
ceilings. The installation, wiring, testing, and maintenance of<br />
such spot detectors make them inconvenient and costly.<br />
For instance, regularly testing the smoke detectors requires<br />
having an inspector introduce smoke into the devices. This<br />
requires safely lifting the inspector to the level of the detector<br />
on a scissor lift, cherry picker, or other access equipment,<br />
which adds to inspection costs. Maintaining and repairing<br />
the smoke detectors is similarly costly.<br />
Compared to traditional spot smoke detectors and other<br />
technologies, this approach dramatically improves warehouse<br />
facility safety by detecting smoke at the earliest possible<br />
stage via numerous sampling points, while reducing false<br />
alarms and maintenance.<br />
Industrial-Sized Smoke Detection Challenges<br />
Warehouses come in a wide range of sizes and contain a wider<br />
range of goods. Most large warehouses have high ceilings<br />
of over 40 ft. (12 m), with some modern automated high rack<br />
storage facilities having ceiling heights over 130 ft. (40 m).<br />
ENERGY EFFICIENT LIGHTING & CONTROLS<br />
The situation is even more challenging in facilities that<br />
operate 24/7, where maintenance is only allowed during a<br />
planned maintenance period.<br />
Linear heat cables and flame detectors are sometimes suggested<br />
offered as a solution and might be tempting from a<br />
maintenance point of view. However, their detection point<br />
(i.e. the flaming stage of fire) is too late to be truly considered<br />
as early warning or adequate detection.<br />
Optimizing Warehouse Smoke Detection<br />
The problem is that in these conditions any smoke is heav-<br />

Instead, as an alternative, ASD technology is a more effective,<br />
early detection option that does not require physical<br />
maintenance to access warehouse ceiling areas above high<br />
bay racks.<br />
Because of such flexibility, ASD smoke detection accommodates<br />
irregular ceiling structures. Moreover, the technology<br />
is not affected by forklifts, robotic gantries, and internal<br />
business operations. Finally, it can even provide detection<br />
within storage racks for the fastest possible response to a fire<br />
threat.<br />
As an example, one system, called VESDA-E VEU, by Xtralis,<br />
a global provider of aspirating fire detection equipment,<br />
draws air samples in a continuous process through holes in<br />
long runs of durable industrial pipe mounted along the walls<br />
and ceiling.<br />
While some ASD products use an LED light source and one<br />
or more photo receivers, the VEU utilizes a flair detection<br />
chamber that uses a short wavelength laser, a CMOS imager,<br />
and multiple photodiodes.<br />
Direct imaging of the sampled particles using the CMOS<br />
camera allows data regarding its size, color and shape to be<br />
derived. Additional data from five photodiodes allows measurement<br />
of light scatter in different directions.<br />
With more detailed information to analyze, the unit is able<br />
to differentiate smoke from other factors that could cause<br />
disruptive false alarms. For warehouse environments where<br />
airborne dust particles may also be present, which can be<br />
confused as smoke by some systems, the unit’s dust rejection<br />
and data analytics minimize nuisance alarms by at least 3<br />
times compared to similar technologies.<br />
Compared to even other aspirating technologies, the system<br />
significantly saves on maintenance costs by allowing long<br />
pipe runs up to 1,310 ft. (400 m) and branched pipe networks<br />
up to 2,625 ft. (800 m) to extend detector coverage. This<br />
reduces the number of detectors required to protect a single<br />
fire zone in a warehouse facility.<br />
Unique Warehouse Challenges<br />
Certain types of warehouses in difficult environments may<br />
still require a high level of fire protection, while posing<br />
unique challenges to smoke detection systems.<br />
Freezers & Refrigerated Storage<br />
While most warehouses with freezers or refrigerated storage<br />
have some form of automatic doors or plastic barrier curtains<br />
to limit warm air ingress, it is inevitable that warm air will<br />
enter the room. This often creates condensation within the<br />
room, which causes icing on ceiling-mounted equipment and<br />
structures close to the entry points.<br />
Even though ASD technology is generally accepted as the<br />
best solution for refrigerated storage facilities, there are<br />
some typical problems associated with its application in such<br />
situations.<br />
Over time, ASD sampling points and pipe within the sub-zero<br />
area can become blocked causing air flow issues and inoperative<br />
detection of smoke. In some instances, the only solution<br />
is to remove the iced up section of the ASD pipe network<br />
and fit a new pipe.<br />
To combat this issue, some providers offer a unique sampling<br />
arrangement that is specifically designed for refrigerated<br />
storage facilities.<br />
For example, Xtralis enables ASD air sampling pipe to be<br />
installed, inspected and maintained outside the refrigerated<br />
environment (i.e. within roof space). This makes it less prone<br />
to blockage due to icing, easier to inspect, and provides a<br />
more robust, longer lasting installation.<br />
Dusty Warehouses<br />
Certain warehouses are very dusty or highly contaminated<br />
environments such that the performance, longevity and<br />
maintenance of the detection equipment are a real concern.<br />
For these environments, ASD systems exist that are design to<br />
withstand the harsh environments in industrial applications,<br />
have superior dust filtration and are enclosed in NEMA 4<br />
equivalent enclosures.<br />
The Xtralis’ VESDA VLI system, for example, comes in an<br />
International Protection Marking IP66 enclosure that provides<br />
total protection against the ingress of dust and strong<br />
water jets. The unit also is designed with a patented intelligent<br />
filter that significantly reduces the amount of contaminants<br />
entering the detector. An integral secondary filter and<br />
sub-sampling probe also rejects larger dust particles, which<br />
further safeguards against nuisance alarms and extends<br />
detector life.<br />
Protecting the Warehouse Bottom Line<br />
Some managers of warehouse facilities may be inclined to<br />
use spot smoke detectors or other traditional devices because<br />
of their familiarity with such systems.<br />
However, those who take advantage of the superior capabilities<br />
of ASD systems will protect lives and inventory to a degree<br />
not previously possible in warehouse settings. This level<br />
of protection will also prevent serious supply chain disruption<br />
as well as liability and litigation in worst-case scenarios.<br />

Michigan Roadwork to See Increased<br />
Risks, Costs in Winter By Shawn D. Lewis | The Detroit News<br />
DETROIT (AP) — The pushing of Michigan’s roadwork into<br />
the colder months comes with great costs and risks for two<br />
of the area’s biggest projects.<br />
MacDonald said the cost for heating and enclosing concrete<br />
pavement is approximately 30 to 50 percent of the cost of<br />
the material and labor, “depending on a number of factors.”<br />
Work laying concrete has continued on Interstate 696 in<br />
Macomb County and Interstate 75 in Wayne County despite<br />
temperatures below or at 40 degrees, which, according to<br />
the American Concrete Institute, is the temperature for<br />
which measures to prevent freezing must be addressed.<br />
Costly precautions must be in place, including protecting<br />
fresh concrete from freezing by placing heaters along a<br />
route to ensure the concrete will take.<br />
“Nobody wants to build roads in the winter,” said Kevin<br />
MacDonald, a principal engineer with Minnesota-based Beton<br />
Consulting Engineers.<br />
In other words, he said, for every dollar spent on a road project<br />
conducted in July, it will cost between $1.30 and $1.50 in<br />
the winter.<br />
“Modern highway construction in cold, wet climates requires<br />
highly durable, as well as high-strength concrete,” he told<br />
The Detroit News. “This can be achieved in cold weather, so<br />
long as precautions are taken to ensure that the concrete has<br />
adequate strength.”<br />
But MacDonald noted taxpayers usually are not footing the<br />
bill for the higher costs.<br />
“Typically, these types of costs fall into means and methods<br />
over the contractor,” he said. “As such, the contractor will<br />
bear the cost.”<br />
A Michigan contractor working on one of the major road<br />
projects said his employees are using necessary precautions,<br />
and they are being closely monitored by the Michigan Department<br />
of Transportation to minimize the risk.<br />

News, Robin Buckson, File)<br />
Joe Goodall, vice president of Dan’s Excavating Inc. in Shelby<br />
Township, which is working on the I-75 project, said yes, contractors<br />
are working to prevent the ground from freezing.<br />
Goodall said workers are “covering the concrete when temperatures<br />
look to be dropping below freezing overnight or<br />
throughout the following days. The specifications for cold<br />
weather protection are being met on the project.”<br />
Do your building engineers understand<br />
the importance of water treatment?<br />
1/3 of water used in commercial buildings is consumed by heating and cooling equipment. What<br />
you don’t know about the water in your building could be costing you. We will meet you at your<br />
facility, bring lunch for your team, and deliver training that gets your engineers’ attention.<br />
They also running heaters on the ground to keep it from<br />
freezing, he said.<br />
“We are keeping the concrete within the specifications for<br />
cold weather paving by any means needed,” Goodall said.<br />

The construction work is happening later in the season<br />
because the projects were delayed in September when the<br />
Michigan Infrastructure and Transportation Association<br />
instituted a work stoppage after multiple failed attempts to<br />
bargain a new contract with the Operating Engineers Local<br />
324. A prior, five-year deal expired in June.<br />
The construction rift prompted the shutdown or partial halt<br />
of 89 Michigan Department of Transportation projects and<br />
75 local projects.<br />
“We are bound by contract with MDOT to complete the project<br />
in a time frame, with the lockout and inclement weather<br />
after the lockout, we are continuing to complete the project<br />
in a timely manner.”<br />
MDOT spokesman Jeff Cranson said state inspectors perform<br />
quality assurance on all contractor efforts throughout a<br />
project.<br />
“So among other things, the inspectors will ensure the heating<br />
and housing is correct,” he said. “Ultimately, the contractor<br />
is responsible for the work completed, and a job is not<br />
accepted until MDOT engineers are confident in the quality.”<br />
And so far, Operating Engineers 324 spokesman Dan McKernan<br />
said he has not heard any complaints from contractors<br />
about corners being cut to get the jobs done.<br />
“Certainly, there is frustration from the workers for having<br />
to work through the winter when it didn’t have to be<br />
this way,” McKernan said. “But I talked to the agent who<br />
oversees the road workers, and there haven’t been any complaints.<br />
At the end of the day, MDOT oversees everything,<br />
and they are very strict.”<br />
The American Concrete Institute recommends specific measures<br />
in its “Guide to Cold Weather Concreting,” noting that<br />
“the necessary degree of protection increases as the ambient<br />
temperature decreases.”<br />
Cold weather concreting “results in extra costs because of<br />
potentially lower worker productivity and additional needed<br />
products such as insulating blankets, tarping and heaters.”<br />
But it adds that these measures also most likely will allow a<br />
project to stay on schedule.<br />
Detroit averages highs of 36.1 degrees and lows of 24.1<br />
degrees in December, according to date from the National<br />
Weather Service in White Lake Township.<br />
Daniel DeGraaf, executive director of the Michigan Concrete<br />
Association, said placing heaters is a major element of<br />
keeping the ground warm. A hydronic heater is used to heat<br />
frozen ground or concrete surfaces by pumping heated fluid<br />
through closed-circulation tubing and a heat exchanger.<br />
“The ground cannot be frozen when building a road on top<br />
of it,” he said. “It can be very expensive.”<br />
He presented an analogy.<br />
Blower Wheels<br />
V Belts<br />
Controls<br />
And More<br />
But Cranson acknowledged risks when concrete is worked on<br />
in the winter.<br />
He released details that noted: “The top couple inches<br />
(estimated) of the concrete below the exposed surface could<br />
potentially act as a sacrificial layer, protecting the inner concrete<br />
mass from frost-related structural damage. But, if not<br />
protected from the cold weather exposure, this top exposed<br />
surface could undergo irreversible damage as it freezes. Over<br />
time, this damaged concrete surface will erode and scale<br />
away, ultimately resulting in loss of the pavement surface.”<br />
Additionally, the details noted, “Placing concrete pavement<br />
on a frozen base could result in significant loss in structural<br />
support as the base begins to thaw in the spring. As the base<br />
freezes, the moisture within it will expand, thus, causing the<br />
base to heave up (water expands approximately nine percent<br />
in volume as it freezes). When the base thaws, it returns to<br />
its original elevation. This will, in turn, take the pavement<br />
downward with it.”<br />
Cranson summed up the lengths being taken to ensure quality<br />
work on roads during the winter by saying: “Contractors<br />
and the MDOT engineers overseeing their work continue<br />
to work very hard to ensure a commitment to quality while<br />
they also work as quickly as possible to make travel lanes<br />
accessible to the public.<br />
“It is a difficult balancing act in ideal conditions, let alone<br />
in inclement weather. Please keep in mind that the people<br />
fixing and building our roads are our sisters, brothers, friends<br />
and neighbors.”<br />

“Imagine running a furnace with the doors and windows<br />
wide open,” he said. “Not only do they have to heat the<br />
ground, but you can’t go as far with the work as you can on<br />
a fall day because you’re limited by how far the equipment<br />
can stretch.”<br />
Meanwhile, Cranson said state inspectors will hold contractors<br />
accountable for the quality of the concrete.<br />
“All materials must meet specifications,” Cranson said.<br />
“Inspection to ensure specification compliance; and enforcement<br />
based on significant research and testing.”<br />

New Mexico May Reconsider Decision<br />
on More Natural Gas Wells By Morgan Lee<br />
SANTA FE, N.M. (AP) — New Mexico oilfield regulators<br />
announced Friday, Jan. 4, that they may revisit a decision to<br />
ease restrictions on natural gas well locations for a Texas-based<br />
company operating in the northwest corner of the<br />
state.<br />
The announcement came as state oversight of wells shifts<br />
to the Democratic administration of Gov. Michelle Lujan<br />
Grisham.<br />
The state’s Oil Conservation Commission scheduled a public<br />
meeting the following week regarding the approved application<br />
from Hilcorp Energy to increase potential well density in<br />
the San Juan Basin area from four wells to eight per 320-acre<br />
tract, or about half a square mile (1.2 square kilometers).<br />
Environmentalists estimate the density decision could concentrate<br />
patterns of oil well development across hundreds of<br />
square miles (square kilometers) of territory.<br />
In a statement Jan. 4, Hilcorp said it would defend the state’s<br />
ruling last year on well densities and highlighted the related<br />
opportunity for new jobs and investments in an economically<br />
depressed region of the state.<br />
“Hilcorp prevailed in this matter by presenting a scientifically<br />
sound case in accordance with all laws and regulations,” it<br />
said.<br />
Hilcorp has said longstanding density limits have prevented<br />
the company from tapping more of a formation called the<br />
Blanco-Mesaverde gas pool.<br />
The approval of the company’s application to increase well<br />
densities late last year prompted an outcry from conservationists<br />
and a rebuke from the state’s independently elected<br />
land commissioner who left office Dec. 31.<br />
Upon taking office last month, Democratic Land Commissioner<br />
Stephanie Garcia Richard urged the state to take up her<br />
agency’s request for an appeal that was rejected by oilfield<br />
regulators as termed-out Republican Gov. Susana Martinez<br />
left office on Dec. 31.<br />
“It is imperative that we make a decision in the region that<br />
ensures long-term sustainability and production that is fair to<br />
every producer in the state,” Garcia Richard said in a statement<br />
Jan. 4.<br />
The State Land Office oversees 14,000 square miles (36,000<br />
square kilometers) of land and additional underground<br />
resources that are used to help fund schools, universities,<br />
hospitals and other public institutions.<br />
The membership of the Oil Conservation Commission is determined<br />
by the governor, a Cabinet secretary and the state<br />
land commissioner.<br />
New Mexico’s first female state land commissioner, Stephanie Garcia Richard,<br />
speaks after taking the oath of office on Jan. 1, <strong>2019</strong>, at the state Capitol<br />
in Santa Fe, N.M. Women including newly inaugurated Gov. Michelle<br />
Lujan Grisham helped Democrats consolidate control over all statewide<br />
offices and New Mexico’s congressional delegation in November elections.<br />

projects and other development across millions of acres of state trust land.<br />

The San Juan Citizens Alliance, an environmental advocacy<br />
group, also has sought a rehearing of the well-density<br />
decision, arguing that it was unfairly shut out of application<br />
proceedings where it hoped to provide testimony about<br />
public-health and environmental impacts.<br />
Erik Schlenker-Goodrich, an attorney for the Alliance, called<br />
the planned meeting a positive development.<br />
“There’s an opportunity to rebuild the credibility of the Oil<br />
Conservation Commission and to ensure that the public has a<br />
voice in oil and gas regulation,” he said.<br />

cooling<br />
systems<br />
designed to save<br />
both water and energy<br />
at new facility<br />
Behind the scenes of the most cutting-edge genetic science<br />
lies the work and expertise of companies like New England<br />
BioLabs, Inc. based in Ipswich, Mass.<br />
Since the 1970s, New England BioLabs has provided enzymes<br />
for use in molecular biology research and clinical trials, serving<br />
a network of customers internationally.<br />
The enzymes produced at New England BioLabs are used<br />
in applications like cloning, DNA modification and protein<br />
analysis — applications which are highly precise, requiring<br />
Plans are reviewed and Decco riggers<br />
complete cooling tower installations<br />
at New England BioLab’s new facility.<br />
An EVAPCO cooling module is lifted into place.<br />
components that are predictable, repeatable and of the<br />
highest quality.<br />
To better serve the ever evolving needs of their customers,<br />
New England BioLabs (NEB) has recently completed the<br />
construction of a 40,000 square foot cleanroom production<br />
facility in Rowley, Mass.<br />
The Right Construction Team<br />
Pulling it all together was the project management firm,<br />
Columbia Construction Company, a Boston-based company<br />
with over 90 years’ experience in multiple sectors: academic,<br />
life sciences, corporate, healthcare and hospitality.<br />
Neal Swain, project manager, explained, “Columbia was<br />
involved with the construction of NEB’s new facility for the<br />
entire process, from design review to final commissioning.”<br />
Columbia worked with AHA Consulting Engineers, Inc.<br />
(AHA) for building’s engineering infrastructure, including<br />
the plant’s process cooling mechanical system. AHA’s clients<br />
include companies such as Vertex, Takeda, Merck, and NEB<br />
itself, as AHA served as the design engineers for its main<br />
facility.<br />
As is customary in the industry, AHA worked with suppliers<br />
to find the right equipment to meet the NEB’s specific<br />
requirements. Manufacturer’s rep firm, Fluid Equipment<br />
Solutions of New England (FES), provided technical assistance<br />
for the cooling system at this new facility.<br />
Tight Tolerances for Cooling<br />
Accurate and robust temperature control of the equipment<br />
and environment is critical to the success of the tightly-controlled<br />
manufacturing processes.<br />
A key component of the cooling system that meets the<br />
stringent cooling needs at NEB’s facility is its fluid cooler,<br />
a 1.6 million BTU closed circuit cooling tower designed<br />
to provide cooling to process water for a wide variety of<br />
sophisticated plant processes.<br />
“The fluid cooler provides condenser water to one side of<br />
a heat exchanger,” said Thomas Joyner, partner, and AHA<br />
project manager. “The process water on the other side of<br />
the heat exchanger serves several pieces of plant equipment<br />
as well as a process chiller to provide chilled water for<br />
manufacturing.”<br />
For such a large, yet critical piece of the cooling puzzle,<br />
AHA considered several options for the fluid cooler. With<br />
the rising cost of energy and concern about water consumption,<br />
the amount of electricity and water used was<br />
an additional factor in deciding which cooling system to<br />
specify.<br />
Ben McLaughlin, sales engineer at FES said, “We compared<br />
the performance of multiple evaporative fluid coolers in<br />
terms of meeting the required temperature as well as energy<br />
and water use.”<br />

system.”<br />
This tight control is what gives NEB the level of utility savings<br />
as well as the consistency and predictability needed for their<br />
manufacturing processes.<br />
Eco-friendly Accessories<br />
The other key evaporative cooling system components are<br />
the water treatment, and the quiet fan, also selected by the<br />
design team. Although water treatment is necessary to maintain<br />
evaporative cooled equipment during wet operation,<br />
a substantial benefit to a primarily dry cooler is that scale<br />
cannot form when the unit is operating in dry operation.<br />
To prevent scale buildup or corrosion from deposits when<br />
water is evaporated in the cooler, the water must be treated.<br />
In order to maintain an environmentally friendly manufacturing<br />
facility, a non-chemical treatment system was provided<br />
for this evaporative water.<br />
Expert hands bring together the cooling tower assembly at New England<br />
BioLab’s new facility.<br />
After careful analysis, EVAPCO’s eco ATWB-H series hybrid<br />
fluid cooler was selected. The system is specifically designed<br />
to optimize both the evaporative (latent) and dry (sensible)<br />
modes of cooling simultaneously — combining the advantages<br />
of an evaporative cooler and a dry cooler into one unit.<br />
A Balancing Act<br />
McLaughlin explains, “There were three aspects of the fluid<br />
cooling system that were critical for this application. The first<br />
was the cooling tower’s wet and dry performance.”<br />
The hybrid fluid cooler has both wet and dry operation with<br />
the ability to handle full capacity in “dry mode” up to an<br />
ambient dry bulb temperature of 50oF. This reduces water<br />
consumption for every hour of operation below 50o when<br />
the water is turned off and the fan alone is doing all the<br />
cooling.<br />
“In addition to water savings, the five-horsepower spray<br />
pump is turned off during dry cooling, and that results in<br />
energy savings when compared to the standard fluid cooler<br />
using evaporative cooling only,” said McLaughlin. “So we<br />
have about 60 percent less water used and a 30 percent<br />
reduction in electricity consumption.”<br />
Process water first enters the dry coil which is outside the<br />
evaporative water spray stream. This coil serves to pre-cool<br />
the high-temperature water. The cooled water then enters<br />
the coil, just below the spray stream. Depending on the dry<br />
bulb temperature, the spray pump may be on or off.<br />
A key benefit of the dry coil, piped in series with the wet<br />
coil, is that the evaporation rate off of the wet coil is maximized<br />
because a significant portion of the heat load from<br />
the process has already been rejected by the dry coil before<br />
entering the wet coil. This means that water is always saved,<br />
even when spray pumps are required for full load.<br />
The additional dry coil also allows for reduced water vapor<br />
leaving the cooling tower, which happens because of<br />
efficient transfer of heat from the process water to the moist<br />
air leaving the cooling tower. Increasing the temperature of<br />
the air leaving the tower, without adding moisture, reduces<br />
its relative humidity from a saturated state (at 100 percent),<br />
which greatly reduces the visible plume.<br />
In order to get the most out of this hybrid system, the fan<br />
and spray pump operation are controlled to maximize<br />
savings. The SAGE® control system provided with the cooler<br />
plays a key role in optimizing water and energy savings.<br />
“The controller leverages outdoor or ambient conditions,”<br />
explained McLaughlin. “Specifically, the wet bulb and dry<br />
bulb temperatures are used to best meet load requirements<br />
while reducing water and energy consumption. This sophisticated<br />
operation is handled in stride by the SAGE control<br />
“We included the Pulse-Pure® non-chemical water treatment<br />
system with the fluid cooler,” McLaughlin explained. “This<br />
system uses a high-frequency electromagnetic pulse to take<br />
care of the corrosive or scale-forming solids that would otherwise<br />
concentrate on the cooler’s components when water<br />
evaporates. It also takes care of anything biological that<br />
we’re usually concerned with because it renders microorganisms<br />
incapable of reproduction.”<br />
In addition to reducing chemicals used on site, the unit itself<br />
produces less sound pollution. The super-low sound fan<br />
selected boasts a 9- to 16-decibel reduction in sound when<br />
compared to the standard fluid cooler fan.<br />
“The reduction in sound is concentrated in the low-frequency<br />
octave band, which travel further distances and penetrate<br />
structures,” explained McLaughlin, “so these are the fans<br />
specifically designed for applications that are sound-sensitive<br />
in nature.”<br />
With EVAPCO’s hybrid fluid cooler serving the manufacturing<br />
process, New England BioLabs’ new cleanroom production<br />
facility achieves both high-quality product and lower water<br />
and energy consumption.<br />
“We took the shell of a building and turned it into a 40,000<br />
square foot cleanroom production facility,” said Swain,<br />
“and the process cooling system assures utility savings while<br />
delivering predictable outcomes for NEB’s customers, both<br />
existing and those we expect to serve in the future.”<br />

Connecticut Taps Nuclear Plants to<br />
Generate Clean Energy<br />
HARTFORD, Conn. (AP) — Nuclear power plants in Connecticut<br />
and New Hampshire made the list of electricity producers<br />
selected Dec. 28 to generate the clean energy needed to<br />
help meet Connecticut’s goals for reducing greenhouse gas<br />
emissions.<br />
Department Energy and Environmental Protection Commissioner<br />
Robert Klee and Democratic Gov. Dannel P. Malloy<br />
announced the state also chose bids submitted from nine<br />
solar projects and one offshore wind project. Final regulatory<br />
approval of power contracts, which still need to be negotiated,<br />
are still required.<br />
“The selection of this diverse portfolio of zero-carbon resources<br />
ensures that Connecticut is doing its part to address<br />
climate change,” Klee said. A 2017 state law required DEEP’s<br />
commissioner to solicit proposals for up to 12 million megawatt-hours<br />
of clean energy annually to meet the state’s<br />
renewable energy goals.<br />
Virginia-based Dominion Energy had sought for months<br />
to have its Millstone Nuclear Power Station in Waterford,<br />
Connecticut, included in the clean energy procurement. Dominion<br />
had argued that the plant faced closure due to rising<br />
expenses and competition from natural gas.<br />
“We look forward to executing the contract with Connecticut’s<br />
utilities shortly,” he said.<br />
State regulators recently determined Millstone was at risk of<br />
early retirement, a move that ultimately allowed the plant to<br />
be part of DEEP’s clean energy auction.<br />
DEEP also selected nine solar projects, including three in<br />
Connecticut, four in Maine and two in New Hampshire.<br />
Additionally, DEEP announced plans to expand upon its June<br />
selection of 200 megawatts of energy generated by the Revolution<br />
Wind offshore project being developed by Rhode Island-based<br />
Deepwater Wind. DEEP said the state will procure<br />
an additional 100 megawatts of power from the wind farm,<br />
located in federal waters, about halfway between Montauk,<br />
N.Y., and Martha’s Vineyard, Mass.<br />
“Offshore wind is fast becoming a centerpiece of Connecticut’s<br />
renewable energy future,” said Jeffrey Grybowski, Co-<br />
CEO of Ørsted US Offshore Wind, which acquired Deepwater<br />
Wind in October. “We’re proud that our Revolution Wind<br />
project will now deliver even more clean energy to Connecticut<br />
communities.”<br />
A top Dominion executive said Dec. 28 that the company is<br />
pleased Millstone is part of the portfolio. DEEP selected a 10-<br />
year bid for about 50 percent of the entire nuclear facility’s<br />
output. DEEP also selected a bid from the Seabrook Nuclear<br />
Power Plant in New Hampshire.<br />
“DEEP’s decision is good news for Connecticut’s economy and<br />
the environment,” said Paul Koonce, EVP, president and CEO<br />
of power generation at Dominion Energy. He said Dominion’s<br />
“zero carbon offer brings at least $670 million in net<br />
benefits to Connecticut customer” and “welcome holiday<br />
news” for the power plant’s 1,500 employees.<br />

ACCESS EVENTS<br />
BISMARCK, N.D. (AP) — The developer of the Dakota Access<br />
oil pipeline missed a year-end deadline to plant thousands<br />
of trees along the pipeline corridor in North Dakota, but<br />
the company said it was still complying with a settlement of<br />
allegations it violated state rules during construction.<br />
Texas-based Energy Transfer Partners, which built the $3.8<br />
billion pipeline that’s now moving North Dakota oil to<br />
Illinois, is falling back on a provision of the September 2017<br />
agreement. The provision provides more time should the<br />
company run into problems providing 20,000 trees to county<br />
soil conservation districts along the pipeline’s 359-mile<br />
(578-kilometer) route across North Dakota.<br />
The deal with North Dakota’s Public Service Commission<br />
settled allegations that ETP removed too many trees in some<br />
areas and that it improperly handled a pipeline route change<br />
after discovering Native American artifacts. The artifacts<br />
were not disturbed.<br />
The agreement required the company to replant trees and<br />
shrubs at a higher ratio in the disputed areas, along with an<br />
additional 20,000 trees along the entire route. ETP filed documents<br />
in October detailing efforts by a contractor to plant<br />
141,000 trees and shrubs, but the PSC asked the company<br />
a month later to provide more documentation that it had<br />
complied with all settlement terms.<br />
tricts due to several factors, including equipment and staffing<br />
issues, difficulties finding willing landowners and poor<br />
planting conditions, according to Perennial Environmental<br />
Services, which ETP hired to handle the work.<br />
A soil conservation district in one of the seven counties<br />
refused to participate at all because it didn’t feel any of the<br />
15 tree species identified in the settlement agreement were<br />
suitable for the county.<br />
The agreement allows for the work to continue into <strong>2019</strong> if<br />
there are problems with the tree supply “or other market<br />
conditions.” Soil conservation districts in six counties have<br />
committed to planting about 16,800 more trees in <strong>2019</strong>, for<br />
a total of more than 25,500, according to Perennial Environmental<br />
Services.<br />
PSC officials weren’t available at press time for comment on<br />
whether the state thinks ETP is justified in prolonging the<br />
plantings into the new year.<br />
Under the agreement, ETP also was directed to develop an<br />
industry handbook on properly handling pipeline route adjustments<br />
and to conduct training. In return, the PSC didn’t<br />
require the company to admit wrongdoing and scrapped a<br />
proposed $15,000 penalty. The agency has the power to levy<br />
up to $200,000 in fines.<br />
Auto-renewal of your annual membership is now available<br />
and easily managed from your phone or other device.<br />
What do I need to do?<br />
Company attorney Lawrence Bender recently submitted a<br />
report from contractor KC Harvey Environmental further detailing<br />
the replanting efforts in the disputed areas. He noted<br />
that in some areas where landowners refused trees, the trees<br />
were reallocated to other landowners “who had the space<br />
and desire to accommodate more plantings.”<br />
Bender in December detailed training that he said surpassed<br />
what was required during the Williston Basin Petroleum Conference<br />
in May, the North Dakota Petroleum Council annual<br />
meeting in September and the Colorado Oil and Gas Association<br />
annual meeting in November.<br />

Army Looks for a Few Good Robots,<br />
Sparks Industry Battle By Matt O’Brien<br />
CHELMSFORD, Mass. (AP) — The Army is looking for a few<br />
good robots. Not to fight — not yet, at least — but to help<br />
the men and women who do.<br />
These robots aren’t taking up arms, but the companies making<br />
them have waged a different kind of battle. At stake is a<br />
contract worth almost half a billion dollars for 3,000 backpack-sized<br />
robots that can defuse bombs and scout enemy<br />
positions. Competition for the work has spilled over into<br />
Congress and federal court.<br />
The project and others like it could someday help troops<br />
“look around the corner, over the next hillside and let the<br />
robot be in harm’s way and let the robot get shot,” said Paul<br />
Scharre, a military technology expert at the Center for a New<br />
American Security.<br />
The big fight over small robots opens a window into the<br />
intersection of technology and national defense and shows<br />
how fear that China could surpass the U.S. drives even small<br />
tech startups to play geopolitics to outmaneuver rivals. It also<br />
raises questions about whether defense technology should<br />
be sourced solely to American companies to avoid the risk of<br />
tampering by foreign adversaries.<br />
Regardless of which companies prevail, the competition<br />
foreshadows a future in which robots, which are already familiar<br />
military tools, become even more common. The Army’s<br />
immediate plans alone envision a new fleet of 5,000 ground<br />
robots of varying sizes and levels of autonomy. The Marines,<br />
Navy and Air Force are making similar investments.<br />
“My personal estimate is that robots will play a significant<br />
role in combat inside of a decade or a decade and a half,”<br />
the chief of the Army, Gen. Mark Milley, said in May at a<br />
Senate hearing where he appealed for more money to modernize<br />
the force.<br />
Milley warned that adversaries like China and Russia “are<br />
investing heavily and very quickly” in the use of aerial, sea<br />
and ground robots. And now, he added, “we are doing the<br />
same.”<br />
Such a shift will be a “huge game-changer for combat,” said<br />
Scharre, who credits Milley’s leadership for the push.<br />
The promise of such big Pentagon investments in robotics<br />
has been a boon for U.S. defense contractors and technology<br />
startups. But the situation is murkier for firms with foreign<br />
ties.<br />
Concerns that popular commercial drones made by Chinese<br />
company DJI could be vulnerable to spying led the Army to<br />
ban their use by soldiers in 2017. And in August, the Pentagon<br />
published a report that said China is conducting espionage<br />
to acquire foreign military technologies — sometimes<br />
by using students or researchers as “procurement agents and<br />
intermediaries.” At a December defense expo in Egypt, some<br />
U.S. firms spotted what they viewed as Chinese knock-offs of<br />
their robots.<br />
The China fears came to a head in a bitter competition<br />
between Israeli firm Roboteam and Massachusetts-based Endeavor<br />
Robotics over a series of major contracts to build the<br />
Army’s next generation of ground robots. Those machines<br />
will be designed to be smarter and easier to deploy than the<br />
remote-controlled rovers that have helped troops disable<br />
bombs for more than 15 years.<br />
The biggest contract — worth $429 million — calls for<br />
mass-producing 25-pound robots that are light, easily maneuverable<br />
and can be “carried by infantry for long distances<br />
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<br />
robots won’t fight — at least, not yet. But they will be designed to help the men and women who do. The companies making them are waging a different<br />
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.<br />

without taxing the soldier,” said Bryan McVeigh, project<br />
manager for force projection at the Army’s research and<br />
contracting center in Warren, Michigan.<br />
Other bulkier prototypes are tank-sized unmanned supply<br />
vehicles that have been tested in recent weeks in the rough<br />
and wintry terrain outside Fort Drum, New York.<br />
A third $100 million contract — won by Endeavor in late<br />
2017 — is for a midsized reconnaissance and bomb-disabling<br />
robot nicknamed the Centaur.<br />
The competition escalated into a legal fight when Roboteam<br />
accused Endeavor, a spinoff of iRobot, which makes Roomba<br />
vacuum cleaners, of dooming its prospects for those contracts<br />
by hiring a lobbying firm that spread false information<br />
to politicians about the Israeli firm’s Chinese investors.<br />

A federal judge dismissed Roboteam’s lawsuit in April.<br />
“They alleged that we had somehow defamed them,” said<br />
Endeavor CEO Sean Bielat, a former Marine who twice ran<br />
for Congress as a Republican. “What we had done was taken<br />
publicly available documents and presented them to members<br />
of Congress because we think there’s a reason to be concerned<br />
about Chinese influence on defense technologies.”<br />
The lobbying firm, Boston-based Sachem Strategies, circulated<br />
a memo to members of the House Armed Services Committee.<br />
Taking up Endeavor’s cause was Rep. Seth Moulton, a<br />
Massachusetts Democrat — and, like Bielat, a Marine veteran<br />
— who wrote a letter to a top military official in December<br />
2016 urging the Army to “examine the evidence of Chinese<br />
influence” before awarding the robot contracts.<br />
Six other lawmakers later raised similar concerns.<br />
Roboteam CEO Elad Levy declined to comment on the dispute<br />
but said the firm is still “working very closely with U.S.<br />
forces,” including the Air Force, and other countries. But it’s<br />
no longer in the running for the lucrative Army opportunities.<br />
Endeavor is. Looking something like a miniature forklift<br />
on tank treads, its prototype called the Scorpion has been<br />
zipping around a test track behind an office park in a Boston<br />
suburb.<br />
The only other finalist is just 20 miles away at the former<br />
Massachusetts headquarters of Foster-Miller, now a part of<br />
British defense contractor Qinetiq. The company did not<br />
respond to repeated requests for comment. The contract is<br />
expected to be awarded in early <strong>2019</strong>.<br />
Both Endeavor and Qinetiq have strong track records with<br />
the U.S. military, having supplied it with its earlier generation<br />
of ground robots such as Endeavor’s Packbot and Qinetiq’s<br />
Talon and Dragon Runner.<br />
After hiding the Scorpion behind a shroud at a recent Army<br />
conference, Bielat and engineers at Endeavor showed it for<br />
the first time publicly to The Associated Press in November.<br />
Using a touchscreen controller that taps into the machine’s<br />
multiple cameras, an engineer navigated it through tunnels,<br />
over a playground-like structure and through an icy pool of<br />
water, and used its grabber to pick up objects.<br />
It’s a smaller version of its predecessor, the Packbot, which<br />
was first used by U.S. troops in Afghanistan in 20<strong>02</strong> and later<br />
became one of soldiers’ essential tools for safely disabling<br />
improvised explosives in Iraq. Bielat said the newer Scorpion<br />
and Centaur robots are designed to be easier for the average<br />
soldier to use quickly without advanced technical training.<br />
“Their primary job is to be a rifle squad member,” Bielat said.<br />
“They don’t have time to mess with the robot. They’re going<br />
to demand greater levels of autonomy.”<br />
It will be a while, however, before any of these robots become<br />
fully autonomous. The Defense Department is cautious<br />
about developing battlefield machines that make their own<br />
decisions. That sets the U.S. apart from efforts by China and<br />
Russia to design artificially intelligent warfighting arsenals.<br />
A November report from the Congressional Research Service<br />
said that despite the Pentagon’s “insistence” that a human<br />
must always be in the loop, the military could soon feel compelled<br />
to develop fully autonomous systems if rivals do the<br />
same. Or, as with drones, humans will still pull the trigger,<br />
but a far-away robot will lob the bombs.<br />

Computer Scientists Study Security<br />
Threats to Smart Homes By Tamara Dietrich<br />
And you’re none the wiser — until you get home and discover<br />
your home’s been hacked. And burgled.<br />
This is just one scenario demonstrating one of many inherent<br />
flaws that computer scientists at the College of William and<br />
Mary discovered in internet-connected smart home devices<br />
during tests they conducted over the summer.<br />
This particular flaw allows hackers to attack a smart home’s<br />
low-security device — a light switch or thermostat, for instance<br />
— and use that access to attack a high-security device<br />
they could not otherwise access.<br />
It’s one example of what’s called lateral privilege escalation,<br />
and experts warn that such smart home hacks are easier than<br />
you might think. They can lead to all kinds of potential mischief,<br />
if not outright harm, from switching off your security<br />
system to cranking up your smart oven until it overheats and<br />
burns the house down.<br />
“The possibilities are limitless,” said Adwait Nadkarni, lead<br />
investigator and assistant professor of computer science.<br />
“There are so many devices in the home that affect your<br />
security, affect the integrity of your home.”<br />
Experts say that in just two years there will be 20 billion<br />
smart home products in use.<br />
William & Mary computer science associate professors Adwait Nadkarni and<br />
Denys Poshyvanyk and their students have identified security vulnerabilities<br />
in smart home devices. Weaknesses in the security of a Web-enabled light<br />
bulb could give hackers access to Web-enabled cameras and security devices,<br />
allowing them to be disabled. (Rob Ostermaier/The Daily Press via AP)<br />
WILLIAMSBURG, Va. (AP) — Say you’re on your laptop at<br />
Starbucks, minding your own business, when an acquaintance<br />
of yours across the room isn’t minding his.<br />
Unbeknownst to you, he’s using the same store Wi-Fi as you<br />
to conduct a virtual invasion of your smart home: accessing<br />
your light switch app and using it to disable your home’s<br />
security camera so real thieves can break in — or walk in, if<br />
he’s disabling the smart lock, too.<br />
“You can imagine the possible combinations of these kinds<br />
of attacks will obviously increase as we’ll have more interconnected<br />
devices,” said associate professor Denys Poshyvanyk.<br />
“At this point, it’s hard for us to imagine what else people<br />
will do.”<br />
Nadkarni and Poshyvanyk co-authored a paper on their work<br />
that they’ll present at the 9th annual ACM Conference on<br />
Data and Application Security and Privacy in Dallas in March.<br />
Student co-authors include Kaushal Kafle and Sunil Manandhar<br />
and post-doctoral fellow Kevin Moran.<br />
In the paper, they lay out the potential misuses of the computer<br />
routines or portions of code that control smart home<br />
products and offer 10 key findings with “serious security<br />
implications.”<br />
“The diversity of these products is staggering,” the paper<br />
states, “ranging from small physical devices with embedded<br />
computers such as smart locks and light bulbs to full-fledged<br />
appliances such as refrigerators and HVAC systems.”<br />
And the risks, it states, can be rather alarming.<br />
“Because many of these products are tied to the user’s security<br />
or privacy (e.g., door locks, cameras), it is important to<br />
understand the attack surface of such devices and platforms<br />
in order build practical defenses without sacrificing utility.”<br />
For their research, Nadkarni and Poshyvanyk focused on<br />
two of the most popular smart home platforms — Google<br />
(Continued on page 56)<br />
54 | Chief Engineer<br />
Volume 84 · Number 2 | 55
Techline<br />
Nest and Philips Hue — that implement home automation<br />
“routines.”<br />
Routines are the interactions between smart home devices<br />
and the apps that control them. They are becoming the heart<br />
of seamless home automation.<br />
According to the paper, there are two broad categories of<br />
routines: one that allows users to “chain together” a variety<br />
of devices using a third-party app interface, and one<br />
that uses a “centralized data store” as a sort of switchboard<br />
where devices and apps can communicate with each other<br />
over the internet.<br />
Both are intended to make smart home automation more<br />
seamless for the user, and both were found to be vulnerable,<br />
giving hackers the ability to attack all the internet-connected<br />
devices in the home.<br />
For the centralized data store platform, for instance, when<br />
you use your mobile app to communicate with a low-security<br />
device — say, a light switch — the device accesses your smart<br />
home using an authorization token.<br />
“Anybody can steal that access token,” Nadkarni said, and<br />
use it to, say, make your smart home think you’re inside and<br />
turn off the security camera.<br />
The scientists insist it’s not that hard.<br />
“You don’t need any specialized education,” said Poshyvanyk.<br />
‘You just need to know how to run certain programs.<br />
Even a high schooler could do that.”<br />
They blame the vulnerabilities on consumer demand and the<br />
headlong rush to meet it.<br />
“Manufacturers race to release these systems without having<br />
a good understanding of how they will be used in the wild,”<br />
Poshyvanyk said.<br />
After the researchers identified the security flaws, they contacted<br />
platform vendors Google and Philips and app developer<br />
and manufacturer TP Link to report what they found.<br />
TP Link fixed the flaw in its latest Kasa Switch light dimmer<br />
app, which prevents the type of theoretical lateral attack<br />
outlined earlier. Philips is expected to roll out a fix to its platform<br />
and Google is working to address vulnerabilities.<br />
But the issue is bigger than one company — it’s the industry<br />
overall that needs to get smarter.<br />
“We’re basically arguing that we need a systemic effort in<br />
terms of properly designing these systems with security in<br />
mind,” Poshyvanyk said.<br />

Fujitsu Introduces RGLX Large, Circular<br />
Flow Ceiling Cassettes<br />
Fujitsu General America introduces the new Halcyon circular<br />
flow ceiling cassette system.<br />
Built to replace the RCLX Large Cassette Series, the new<br />
RGLX Series features circular airflow for more consistent air<br />
distribution. Through the use of a DC twin rotary compressor,<br />
DC fan motor and optimal refrigerant cycle control, the RGLX<br />
line also offers improved energy efficiency. The completely<br />
redesigned units achieve up to 21.4 SEER.<br />
By using 360-degree louvers, the circular airflow design<br />
allows conditioned air to reach every corner of a room. Each<br />
louver can be programmed individually to customize airflow<br />
for maximum occupant comfort and room layout.<br />
With the new airflow structure and four-speed fan control,<br />
sound levels are dramatically reduced. When in Quiet Mode,<br />
indoor noise levels are as low as 28 decibels.<br />
Fujitsu’s new RGLX Series features circular airflow for more consistent air<br />
distribution.<br />
The new units work with wired or wireless controls (2- or<br />
3-wire controls), and Fujitsu’s Human Sensor Kit, which automatically<br />
saves energy by detecting occupancy. Integration<br />
with a third-party thermostat is also simple, with the use of<br />
Fujitsu’s thermostat adapter.<br />
Five sizes are available, from 18,000 to 42,000 BTUH, two of<br />
which meet Energy Star qualifications. A 48,000 BTUH unit<br />
will be available in early <strong>2019</strong>. Black or white grilles are available<br />
for all sizes.<br />
Delta-Q’s products provide premium “charge quality” for<br />
lithium-ion and lead acid batteries using charge profiles<br />
developed in Delta-Q’s battery lab. These high-performance<br />
profiles balance battery life, longevity and charge time<br />
requirements. Delta-Q has commercialized more than 200<br />
charge profiles, ensuring that users experience better performance<br />
and battery life for their battery pack choices.<br />
Delta-Q is now accepting RC1000 sample requests, with full<br />
commercial production available now.<br />

EVAPCO Water Saver Provides<br />
Pre-treatment for Evaporative Cooling<br />
Equipment<br />
EVAPCO Water Systems has introduced the Water Saver, a<br />
device that substantially reduces water use for evaporative<br />
cooling equipment — whether new, or as a retrofit.<br />
Just recently, an Indiana school with a 1,200-ton HVAC system<br />
reduced water consumption by 1.5 million gallons/year<br />
with the technology.<br />
Water Saver is a capacitive deionization pre-treatment<br />
system to improve the efficiency of heat transfer and water<br />
efficiency for evaporative cooling systems. The capacitive<br />
deionization technology reduces dissolved ion concentrations<br />
to lower makeup water conductivity prior to use in evaporative<br />
cooling systems. Dissolved ions are removed from makeup<br />
water as they are attracted to the charged capacitors.<br />
Water Saver improves water efficiency by increasing operating<br />
cycles of concentration; this reduces blowdown and the<br />
use of treatment chemicals. Water Saver lowers cost of ownership,<br />
provides a 75-90 percent recovery rate, and improves<br />
a facility’s LEED rating. The technology is available in nine<br />
different configurations.<br />

Ashrae Update<br />
ASHRAE Publishes Updated<br />
Residential, Construction Standard<br />
ATLANTA – ASHRAE has released an updated edition of ANSI/<br />
ASHRAE/IES Standard 90.2-2018 Energy-Efficient Design of<br />
Low Rise Residential Buildings. The standard establishes<br />
minimum whole-building energy performance requirements<br />
(design, construction, and verification) for energy-efficient<br />
residential buildings.<br />
The 2018 revision of Standard 90.2 outlines cost-effective<br />
residential building energy performance measures that are<br />
at least 50 percent more efficient than those defined by the<br />
2006 International Energy Construction Code (IECC).<br />
“Standard 90.2 provides a mechanism by which any residential<br />
building design can be easily evaluated against performance<br />
objectives,” said Theresa Weston, Ph.D., chair of<br />
the Standard 90.2 committee. “This update to the standard<br />
offers better alignment between this standard’s requirements<br />
and marketplace product availability as well as some<br />
revisions to improve the document’s clarity and internal<br />
consistency.”<br />
The 2018 edition of Standard 90.2 provides:<br />
• Clarification for modeling software requirements<br />
• Guidance on the use of international climate data presented<br />
in ASHRAE Standard 169<br />
• A new normative appendix on proper installation techniques<br />
for critical thermal resistance building components<br />
• Improved prescriptive envelope performance data tables<br />
• New performance specifications for ground-source heat<br />
pumps<br />
• Minimum lighting efficiency provisions for single-family,<br />
large single-family, and multifamily homes<br />
• Guidance on pool heater pilot lights, pump motor efficiency,<br />
and exterior de-icing systems<br />
• Clarifications to multi-zonal building air-leakage testing<br />
procedures<br />
The cost of ASHRAE Standard 90.2-2018 is $94 for ASHRAE<br />
members ($110, non-members). To order, visit www.ashrae.<br />

St. Cloud Wastewater Plant Fueled by<br />
Beer, Byproducts By Anna Haecherl | Saint Cloud Times<br />
ST. CLOUD, Minn. (AP) — Whenever you dump something<br />
down the drain, it goes to the city of St. Cloud’s NEW (Nutrients,<br />
Energy and Water) Recovery Facility, where nutrients<br />
are recovered, waste is treated, and clean water is sent back<br />
into the environment.<br />
But large-scale beverage producers — who have high-sugar<br />
waste filled with potential energy — get special treatment<br />
when it comes to the byproducts created at their facilities.<br />
“We can treat it in a different manner that uses a lot less<br />
electricity, and that we can use to make a fuel,” said Pat<br />
Shea, public services director for the city.<br />
Beverage producers have been bringing what Shea calls<br />
high-strength byproducts to the plant for two years, the<br />
Saint Cloud Times reported. For example, Shea said, a beverage<br />
company or brewery will brew a batch of product, and<br />
once it’s done, the company will clean its production lines<br />
and flush everything out to prepare equipment for the next<br />
batch.<br />
That first rinse will still have product in it, Shea said, and<br />
producers can either put it down the drain, or collect it and<br />
bring it to the NEW Recovery Facility.<br />
Shea said the facility has arrangements with Beaver Island<br />
Brewing, Viking Coca-Cola, Cold Spring Brewing and other<br />
local producers.<br />
“Anything we can do to reclaim this product, recover energy<br />
and use it to run the facility, the more efficient we are,” Shea<br />
said.<br />
High-strength byproducts — like expired soda or beer, residue<br />
left over from the brewing process, or a batch of product<br />
that just didn’t turn out right — are put into anaerobic<br />
digesters along with municipal solids from wastewater — like<br />
A large engine runs on biogas at the Wastewater Treatment Facility in St.<br />
Cloud, Minn. Whenever you dump something down the drain, it goes to<br />
the city of St. Cloud’s NEW (Nutrients, Energy and Water) Recovery Facility,<br />
where nutrients are recovered, waste is treated, and clean water is sent<br />
back into the environment. (Dave Schwarz/St. Cloud Times via AP)<br />
human waste, food waste, and solid residue from cleaning<br />
processes — to produce methane gas.<br />
“We take that high-strength waste and we put it into an<br />
anaerobic conditions, meaning without oxygen,” Shea said.<br />
“Then micro organisms that are in those digesters ... will<br />
consume that material for their respiration. It’s a biological<br />
process, and, as they use it for their processes, they create<br />
methane gas.”<br />
The gas is used to power an onsite generator or run boilers<br />
that heat the digesters converting the byproducts into<br />
methane.<br />
It’s a win-win, Shea said. Instead of dumping the waste and<br />
using more energy to have it treated at the plant, the byproducts<br />
are being used to power the NEW Recovery Facility.<br />
At Beaver Island Brewing, co-founder Nick Barth said waste<br />
wasn’t such a big issue when they first started at their downtown<br />
brewery. But when they opened their new facility in<br />
May 2017 near St. Cloud Regional Airport and started brewing<br />
at a scale four or five times greater, the decision to bring<br />
byproducts to the NEW Recovery Facility instead of putting<br />
them down the drain was an easy one.<br />
“That’s cool because we’re making energy for the city,” Barth<br />
said. “But what’s even cooler is that we’re drastically reducing<br />
our carbon footprint.”<br />
Barth said the brewery captures and harvests its yeast slurry<br />
and trub — a sugary substance and hop remnants left over<br />
after the brewing — to bring to the NEW Recovery Facility.<br />
“It almost looks like a cream-of-wheat-meets-gelatin (substance)<br />
if I could describe it as anything,” Barth said of the<br />
yeast slurry. “Now instead of sending things down the drain<br />
and having them have to be processed at the wastewater<br />
treatment facility ... we’re bypassing that entire process and<br />
they’re making energy from it.”<br />
About a year and a half ago, Barth said Beaver Island brewed<br />
a batch of beer that just didn’t come out as expected.<br />
“There wasn’t anything technically wrong with it,” Barth<br />
said, but it just didn’t smell and taste exactly like what he<br />
was looking for.<br />
So instead of dumping it down the drain, Beaver Island loaded<br />
up the beer and brought it to the NEW Recovery Facility.<br />
“Pat probably loves when we have a beer go in the wrong<br />
direction, because it generates a lot of energy for them,”<br />
Barth said with a laugh. “But for us, we want to do it as little<br />
as possible.”<br />
It takes about 5.7 million killowatt-hours to power the NEW<br />
Recover Facility each year, according to Assistant Public<br />
Utilities Director Tracy Hodel. In 2018, the facility produced<br />
roughly 85 percent of its energy demand onsite through<br />
solar and methane conversion.<br />
Hodel said 7 percent of that 85 percent of needed energy<br />
that is produced onsite comes from solar arrays at the<br />
facility. The rest (about 80 percent of the plant’s total energy<br />
demand) comes from the methane produced in the facility’s<br />
anaerobic digesters.<br />
“There’s still some (power) that we’re buying,” Hodel said,<br />
but there are plans to add a second generator and have the<br />
facility running completely on energy produced on site by<br />
the end of 2<strong>02</strong>0.<br />
“With adding an additional generator, we will be able to<br />
produce exactly, if not a little bit more, of our total demand.<br />
We’re looking at adding a second generator... and we’re also<br />
looking at adding more solar arrays onsite,” Hodel said.<br />
The second generator could be installed as early as fall of<br />
<strong>2019</strong>, Hodel said, but the facility expects to have it up and<br />
running by spring of 2<strong>02</strong>0.<br />

Mathematical Probability<br />
Source: engineering-humour.com/engineering-jokes.html<br />
Every Friday afternoon, a mathematician goes down to the<br />
bar, sits in the second-to-last seat, turns to the last seat, which<br />
is empty, and asks a girl who isn’t there if he can buy her a<br />
drink.<br />
JANUARY SOLUTION<br />
The bartender, who is used to weird university types, always<br />
shrugs but keeps quiet. But when Valentine’s Day arrives, and<br />
the mathematician makes a particularly heart-wrenching plea<br />
into empty space, curiosity gets the better of the bartender,<br />
and he says, “I apologize for my stupid questions, but surely<br />
you know there is NEVER a woman sitting in that last stool.<br />
Why do you persist in asking out empty space?”<br />
The mathematician replies, “Well, according to quantum<br />
physics, empty space is never truly empty. Virtual particles<br />
come into existence and vanish all the time. You never know<br />
when the proper wave function will collapse and a girl might<br />
suddenly appear there.”<br />
The bartender raises his eyebrows. “Really? Interesting. But<br />
couldn’t you just ask one of the girls who comes here every<br />
Friday if you could buy HER a drink? Never know — she<br />
might say yes.”<br />
