Both chambers of Congress are struggling to
find a way to pass the remaining spending bills before the
Republicans turn out the lights, pack up their offices, and turn the
keys over to the Democrats. With Congress officially in recess until
Dec. 4, and a constitutional deadline of noon on Jan. 3 when the
109th Congress officially closes, there is scant time to finish the
11 remaining appropriation bills.
The Senate started work on the remaining
spending bills last week by passing the Military Construction -
Veterans Affairs Appropriations bill, but conservatives who believed
the Republican leaders would use the appropriations bill as a
vehicle for an omnibus bill with a long list of earmarks and policy
riders stopped it procedurally. Senate conservatives also have
placed holds on all remaining spending bills in the Senate,
effectively preventing them from moving forward.
At this juncture, it appears unlikely that the
remaining spending bills can be passed individually, or grouped
together in an omnibus package. Essentially the Republicans have two
remaining choices: a short-term Continuing Resolution (CR) lasting
until sometime next year, or a long-term CR through the full fiscal
year.
The current CR funds transportation projects at
last year’s levels, essentially placing the difference between what
was authorized in SAFETEA-LU for the highway and transit programs in
2006 and 2007, equal to about $3.5 billion, in jeopardy.
If Congress passes a short-or long-term CR
without allocating the full amount authorized by SAFETEA-LU,
Transportation and Infrastructure Committee Chairman, Don Young
(R-Alaska), could raise a point of order against the legislation.
However, House rules also allow leadership to waive points of order,
to smooth passage of difficult legislation. There is no
corresponding point of order procedural rule in the Senate, but
Senate Environment and Public Works Committee Chairman James Inhofe
(R-Okla.) does have a number of options to slow or stop a CR that
does not conform to the funding levels authorized by SAFETEA-LU.
If a long-term CR is passed without
specifically obligating transportation funds at the SAFETEA-LU
levels, the $3.5 billion would essentially be lost, although future
spending bills could reinstate the funds.
A short-term CR would delay final approval
until sometime next spring, but the incoming House Transportation
and Infrastructure Committee Chairman, James Oberstar (D-Minn.),
would be expected to prevail in a fight to ensure the total $39.1
billion for transportation is obligated. How quickly the next
Congress can deal with the remaining spending bills is very
uncertain. Several weeks will be necessary for committees to
organize.
It is possible Congress could include language
in the CR specifically obligating the transportation funding for the
year at the level authorized by SAFETEA-LU. This option will not be
easy, as every other interest group will also be trying to get their
funding obligated in a short- or long-term CR.

The metal and non-metal mining industries, at
press time, have experienced 24 fatalities in 2006, with the death
of 41 year-old equipment operator on Nov. 10 at a Minnesota
construction sand and gravel operation, according to a Mine Safety
and Health Administration (MSHA) Fatalgram report.
The equipment operator, who had four years of
mining experience, was killed when the victim and a co-worker were
standing underneath the head pulley section of a conveyor preparing
to attach a chain that was to be used to move the conveyor, and the
bolts connecting the conveyor truss sections in the conveyor’s frame
failed — causing the head pulley section to fall and strike the
victim.
At press time for the Dec. 1 edition of
Aggregates Manager e-News, this was the fourth falling material
fatality in 2006, according to MSHA.
There were 33 fatalities reported in the
metal/non-metal mining industries, and three falling material
fatalities as of the same date of this incident in 2005, according
to MSHA.
MSHA offers the following best practices to
avoid future fatalities:
-
Stop, Look, Analyze, and Manage (SLAM) each
task to identify all potential hazards before performing
maintenance work. Practice safe work habits during the entire
task.
-
Train miners in safe work procedures before
beginning repairs.
The report, “Non-fatal
Occupational Injuries and Illnesses Requiring Days Away from Work in
2005,” just released by announced by the U.S. Department
of Labor’s Bureau of Labor Statistics (BLS), revealed another
decline in the rate of workplace injuries and illnesses in private
industry that required recuperation away from work.
The BLS released two new Web-based
tools this past year for analyzing occupational injury and illness
data. Profiles on the Web (http://data.bls.gov/GQT/servlet/InitialPage)
provides access to injury and illness data by industry, demographic
characteristics, and case characteristics, and will be updated soon
to include prior years’ data.
A second Web tool (http://data.bls.gov/IIRC/)
allows employers to compute their own injury and illness incidence
rate for safety management purposes and compare their rate to the
rate for their industry.

Bureau of Labor Statistics, including charts detailing where the
construction industry falls in terms of occupational injuries and
days away from work, go to

The U.S. transportation construction
industry has a bold new vision to help address America’s surface
transportation challenges and the federal government must continue
to play a key role in ensuring a safe and efficient national road
network in the post-Interstate Highway System era.
That’s the message the American
Road & Transportation Builders Association (ARTBA) delivered Nov. 16
to the National Surface Transportation Policy and Revenue Study
Commission.
2006 ARTBA Chairman Mike Walton,
the Ernest H. Cockrell “Centennial Chair in Engineering” at the
University of Texas, testified on ARTBA’s behalf at a commission
hearing in New York City called to discuss the current conditions,
future needs and financing alternatives for the nation’s
transportation system. The commission was established under
provisions in the 2005 highway and transit law, known as SAFETEA-LU.
According to the U.S. Census
Bureau, the U.S. population is expected to reach 400 million people
by 2043. This reality will have serious consequences for the future
mobility of motorists, ARTBA testified.
“Between now and 2043 based on
current highway investment and usage trends, U.S. highway capacity
will only grow nine percent, but traffic levels will balloon by 135
percent to more than seven trillion vehicle miles traveled
annually,” Walton says. “As a result, the average motorist can
expect to spend 160 hours stuck in traffic delays, or the equivalent
of four weeks each year—a 112-hour-per-year increase in lost time
from the current level.”
The movement of freight also will
be greatly impeded by inadequate transportation capacity.
Walton cited a Federal Highway
Administration (FHWA) report showing that bottlenecks are causing
trucks more than 243 million hours of delay annually, at a cost of
nearly $8 billion.
“If the U.S. economy grows at a
conservative annual rate of 2.5 to 3 percent over the next 20 years,
domestic freight tonnage will almost double and the volume of
freight moving through the largest international gateways may triple
or quadruple,” the FHWA report says. “Without new strategies to
increase capacity, congestion at freight bottlenecks on highways may
impose an unacceptably high cost on the nation’s economy and
productivity.”
In the short-term, the federal
Highway Trust Fund is facing a severe cash crisis and maintaining
surface transportation investment levels in the future is in serious
doubt, Walton told the commission.
To address these needs now and
ensure there are sufficient resources to maintain current
conditions, Congress should be looking seriously at all options to
generate new revenues for highway, bridge and transit improvements,
including an increase in the federal motor fuels tax, the ARTBA
chairman said.
In the long-term, America needs a
new national vision to help strategy to facilitate the efficient and
secure movement of people and freight, Walton said.
He shared with the commission a
plan approved last Sept. by the ARTBA Board of Directors that
recommends revising the structure of the federal surface
transportation program to consist of two separate, but equally
important components:
The current highway and
transit programs must be significantly better funded through the
existing user fee structure and reformed to address future
safety and mobility priorities. They should focus attention and
resources on upgrading and protecting the nation’s enormous past
investments in surface transportation infrastructure.
The federal government must
initiate a new program, funded with new, “fire-walled”
freight-related user fee mechanisms that over the next 25 years
will greatly expand the capacity of the nation’s intermodal
transportation network. Its centerpiece would be the initiation
of a well-funded “Critical Commerce Corridors (3C) Program”
aimed at improving U.S. freight movement and emergency response
capabilities.

Swiss-based Holcim, the world’s
second-biggest cement producer, is poised to go it alone with a
black economic empowerment (BEE) partner in a R6.82 billion
transaction that is intended to result in Holcim South Africa
getting a black controlling shareholder.
However, Aveng, which has a 46
percent stake in Holcim SA, appears to be preparing to exercise its
pre-emptive rights and acquire 100 percent of the cement company.
Apparently the JSE-listed Aveng,
South Africa’s largest construction and engineering company, was
initially asked to waive its rights to acquire the shareholding
Holcim intends to sell to empowerment group AfriSam Consortium (ASC),
which is headed by Eltie Links, the former trade negotiator and
South African ambassador to the EU.
However, Carl Grim, Aveng’s chief
executive, on Nov. 25 denied that Aveng had taken a decision to
waive its pre-emptive rights and take up the offer to acquire a
shareholding in ASC.
Grim said the company would inform
the market of any decision related to the transaction as soon as it
was taken.
Grim said it would be “absolutely
no problem at all” for Aveng to raise the R6.8 billion funding to
exercise its pre-emptive rights and obtain shareholder approval
within 30 days of a valid offer being tabled.
However, at the weekend Links said
this condition was there as a “courtesy” to Aveng.
“We understand that Aveng have
since made clear that they do not intend to waive their pre-emption
rights and so, from ASC’s perspective, we are quite happy to waive
this condition precedent and simply proceed.
“We see this deal as being in the
best interests of Holcim SA, this industry and the country. I made
clear to Aveng when we last met that we intended to see this
transaction completed as anticipated, with or without their
support.”
Links said Aveng’s management was
not the type of partner ASC could have a long relationship with
“given clearly differing perspectives on the fundamentals of black
economic empowerment”.
Lawyers close to the transaction
have confirmed Holcim and ASC can waive the Aveng condition
together.
Mofasi Lekota, the chief executive
of ASC, said the group understood that Aveng also did not intend to
stay in the business if the consortium took control of Holcim SA.
President Thabo Mbeki last week
discussed the transaction with a delegation including Tom Clough, a
member of the executive committee of Holcim; Edward Chadwick of
Fenix Partner, the transaction advisers to Holcim; and Links and
Lekota.
This led to Mbeki devoting his
weekly ANC newsletter to the proposed deal and black empowerment.

Plunging water levels, lack
of dredging take toll; Great Lakes’ limestone tradeoff 4.5 percent
in October
CLEVELAND—Shipments of limestone on the
Great Lakes totaled 4.1 million net tons in October, a decrease of
4.5 percent compared to a year ago. Loadings were more than 10
percent behind the month’s 5-year average.
Although water levels on the Great Lakes
usually begin their seasonal decline in the fall, the drop is
occurring faster than normal this year, and so further amplifying
the lack of adequate dredging in many ports and waterways. Cargo
totals are being negatively impacted. Vessels in the limestone
trade, for example, forfeit anywhere from 80 to 125 net tons for
each 1-inch reduction in loaded draft.
For the year, the Lakes limestone trade stands
at 31.5 million net tons, a decrease of 2 percent compared to the
same point in 2005. Shipments are, however, slightly ahead of the
5-year average for the January-October timeframe.

Shortage of rock in New
Zealand adding to road costs
AUCKLAND, New Zealand—A shortage of rock
in Auckland could be adding tens of millions of dollars to roading
costs and the aggregate industry blames local authorities for
restricting the development of quarries in the region.
Aggregate comes from quarries but the industry
says local government is allowing subdivisions to creep too close.
“We’re just as important as water, we’re just
as important as electricity, you need aggregates,” says Bruce Taylor
from the Aggregate and Quarry Association.
“We want them to understand they can’t just
shut the door on us.”
Chris Ellis from Winstone Aggregates says three
major quarries have closed in the last five years.
“We’ve really lost a third of the aggregate
production in the Auckland region,” says Ellis.
The industry has been forced to truck in 60,000
trailer loads a year — adding millions of dollars to the cost of
roads.
“You’ve got a hundred million dollars of
additional cost or potentially a hundred million dollars less
roading that you can build,” Ellis says.
Associate Energy Minister Harry Duynhoven says some local
authorities need to understand that mining and quarries have changed
dramatically since they were seen as “very grubby low tech
industries.”
Good aggregate undergoes stringent tests and
needs to be both durable and weather resistant.
The nation’s highway manager, Transit New Zealand, says there is
surprisingly little quarryable rock of good quality left in the
country.
Alternative materials are being trialed like metal byproducts or
glass but the industry believes there is no substitute for good rock
even if it comes at a price.

Maintenance
Top Tank Tune-Up
Tips
Sort out how
to properly care for your classifier. Although they are designed
to be problem-free, maintenance is still a top priority.
by
John Bennington
Here’s some good news: Your classifying system
is designed to run trouble-free — a great “problem” to have.
For six months, a year, or even two years, your
classifying tank might run without a glitch before developing a
problem. And at that point, you simply fix the broken piece, and
then go on, right? Unfortunately, that’s not exactly the case. And
it doesn’t mean that a classifying system is maintenance-free.
The problem is that because classifiers run so
well day-in and day-out, producers tend to overlook routine,
preventive maintenance until something wears out. But simple,
routine maintenance will keep your tank running at its best. The
adage, “If it isn’t broken, don’t fix it,” is indeed not the best
rule of thumb with any piece of mechanical equipment. Because while
it seems your tank may be running well, your stockpile may tell a
different story — especially when it proves to be contaminated or
out of spec.
Overlooked procedures
The most commonly overlooked routine procedure
for classifying plants may be maintenance of the hydraulic system.
Producers should change the hydraulic oil at least once a year, but
this recommendation is oftentimes dismissed. In northern climates,
it’s convenient to handle the hydraulic oil change during a
shutdown. In southern climates, where the tank is run year-round,
the hydraulic fluid should be changed as frequently as every 10
months. Failure to change this fluid can result in contaminated
and/or overused fluid, which can plug the hydraulic system —
ultimately causing one or more cylinders in your tank to stop
working.
While your classifier operator/service manual
will give you the proper procedure for changing your tank’s oil,
don’t fall into a common practice of dumping the hydraulic oil into
the open reservoir; instead, use a filling tube. This tube has a
strainer that keeps foreign matter out of the reservoir, while it
simultaneously regulates the flow of oil.
Dumping tends to stir up the unavoidable
clumped oil that resides at the bottom of the reservoir. Foreign
matter and oil clumps then pump through the hydraulic system,
clogging the system and causing sporadic valve operation or even
complete shutdown, taking your material out of spec.
Another frequently skipped maintenance
procedure is checking the connectors between the valve rods, the
bindicators (sensing paddles), and the hydraulic cylinders. These
connectors are nothing more than cotter pins that can wear and rust,
so if they are not checked regularly, you won’t know if you have
sand at each station in your tank. If a valve actually falls off
from rust or wear, the cylinder will actuate, but the valve won’t
open. In either of these situations, you will be producing non-spec
material because the controllers won’t be able to mechanically make
the tank do what it’s designed to do. These connectors should be
checked monthly.
What’s the source?
A problem that seems to occur frequently with
classifying tanks is the need to regularly replace blown fuses. This
procedure isn’t difficult; it’s just a hassle. But the key is that
fuses should not blow, so the best practice is to look for the cause
of the problem. If your fuses are blowing regularly, you could have
solenoid damage or a short in the system. Locate and repair the
cause to stop this problem from occurring.
Valve leakage is another common complaint from
producers operating this equipment. Often, valves in the bottom of
the tank are allowed to leak or even gush material and water from
the tank. This practice changes the material split point in the
tank, and can contaminate your stockpiles. The valve rods must be
“snugged down” to the floor of the tank. But don’t worry — as long
as the rod is not bending or forcing the valve bridge up, the rod
should be long enough to seal the valve into the valve seat.
If you keep all these tips in mind and remember
that while your classifying tank is designed to work trouble-free,
it’s still a machine with moving parts — and therefore requires
routine maintenance — you can maximize production and performance,
and minimize unplanned shutdowns. By performing these simple tasks,
you’ll see that a little TLC will ensure your classifying tank truly
does operate without a problem.

Classifer
tank maintenance ‘cheat sheet’
Some of the best practices for regular
classifying system maintenance on a daily, monthly, and annual basis
are the following:
Daily
- Check outside of tank for leaks;
- Check water supply valves are set
correctly;
- Check for leaks in valves;
- Check for holes in the screen or rocks
jumping from screen onto valve bridge or into tank; and
- Check fuses in panel (if blown, these can
indicate solenoid damage).
Monthly
- Drain tank and check each valve for proper
stroke and seating (i.e., does it open, does it leak?);
- Check hydraulic system (hydraulic
pressure, oil level, look for leaks); and
- Check to make sure bindicator paddles are
attached and turning.
Yearly
- Change hydraulic oil and filters;
- Replace worn valves or seats;
- Check solenoids (especially at stations 1,
2 and 3); and
- Level the weirs.
Controllers: Basic Daily Electrical Maintenance
- Check fuses and replace as necessary;
- Check panel lights and replace as
necessary; and
-
Check cable and power
connections.

stop working.

If you allow your valves to leak or to gush material and water from
the tank, it will cause the material split point in the tank to
change, resulting in your product to be out-of-spec and/or
contaminated. “Snug down” your valve rods to the floor of the tank.

spring. The first in Nordberg’s line of high-performance cone
crushers, the HP4 is said to produce much finer products with fewer
crushing stages than competing units. Metso claims it combines
optimized speed with a large throw to provide the highest reduction
ratios of any cone crusher on the market today.
HP4 features include dual acting hydraulic
tramp release cylinders that allow the unit to pass tramp iron that
Metso says would stall or damage other crushers. An advanced
fastening system for the mantle and bowl liner eliminates the need
for backing material and makes liner changes quicker. The unit has
thicker liners for longer life and Nordberg has greatly simplified
the replacement procedure.
Scale monitoring software
PC Scale has developed a Scale
Monitoring Module that helps producers audit scale activity by
logging ticketed and non-ticketed weighments, ensuring that all
traffic crossing the scale is legitimate, and that no vehicles cross
the scale without a weighment being captured.

Chevron’s
Lubricants University, an
educational website, is introducing two new courses,
“Automotive Grease” (which covers off-road vehicles) and “Industrial
Grease” as part of its course catalog.
The two modules are self-study, Web-based
programs designed for maintenance professionals and industrial end
users interested in expanding their knowledge of proper grease use
and formulations.
The “Automotive Grease” course provides
information on how grease products differ in terms of performance,
base oil, additives and thickener types. In addition, the module
offers an overview of automotive grease, examines lubrication
performance specifications and looks at automotive grease products
currently in use.
The course increases awareness of the
specialized automotive greases designed to meet the requirements of
highway automobiles and trucks, as well as off-road wheel and track
vehicles.
The “Industrial Grease” course covers the
appropriate quantity, re-greasing intervals, and product selection
for proper lubrication in industrial applications. The course also
describes how to successfully implement industrial greasing programs
in such applications as electric motors, pumps and conveyors, and
pins and bushings found in cranes and other manufacturing equipment.
“Industrial Greases” addresses these issues and
also provides an understanding of what grease is, performance
specifications, industrial grease products and the correct
application of industrial lubrication.
Courses are available to the general public. To
purchase a course by credit card, call the Chevron Fulfillment
Center at 1-866-7LUBESU (866-758-2378). A subscription program is
available for companies interested in offering training to multiple

Opportunity International, an
organization committed to solving global poverty, announced a
philanthropic grant of $1.2 million from Caterpillar Inc.
through the Caterpillar Foundation. Caterpillar has provided a dozen
moderate-sized grants to Opportunity International since 1994, and
this latest donation represents the largest gift ever by Caterpillar
to a microfinance organization.
The grant will assist Opportunity International
in expanding initiatives in China and six African nations. A pioneer
in microfinance since 1971, and today one of the largest
microfinance organizations, Opportunity International offers small
business loans, insurance, banking services and business training to
the poorest of the working poor in 28 countries worldwide.
The grant comes as Opportunity International
expands its presence in Asia and Africa. Approximately $750,000 of
the Caterpillar Inc. funding is allocated to support Opportunity
International’s programs in China. The new funding is expected to
create about 5,000 new jobs in the city of Hefei in Anhui province
over the next three years, providing the capital to benefit about
25,000 people. The Caterpillar grant is the largest gift received by
Opportunity International for its operations in China, where the
organization opened an office in 2003.
The remainder of the grant will be distributed equally to
Opportunity International’s programs in Kenya, Uganda, Ghana,
Mozambique, Malawi, and Rwanda. In addition to providing credit in
the form of microloans, Opportunity International has opened banks
in many countries in sub-Saharan Africa that feature innovations
such as biometric fingerprint identification technology, mobile
ATMs, savings accounts, low-cost money transfers and health, life
and even crop insurance for the poorest of the working poor.
The Africa portion of the grant will help more
than 28,000 poor people, bringing the total expected impact of the
Caterpillar grant to benefit more than 53,000 workers, entrepreneurs
and their family members.
