In This Issue:
Highway Trust Fund to Shut Down Monday - 
U.S. DOT to Furlough Workers Tuesday
 

The federal Highway Trust Fund will shut down first thing Monday, suspending all payments to state transportation departments, and four U.S. Department of Transportation agencies are expected to furlough employees beginning Tuesday after Congress was unable to reach an agreement this week on legislation to extend surface transportation authorization past its Sunday expiration date.

"No reimbursements to states for their share of federal highway funds, no vouchers they have submitted or will submit to the Federal Administration will be able to be paid beginning Monday, March 1," House Transportation and Infrastructure Committee Chairman James Oberstar, D-MN, told reporters on a conference call Friday afternoon.  "The shutdown of the federal highway program means the Federal Highway Administration will not be able to reimburse states for any federal highway or transit funds."

Both chambers passed extension bills last week but could not agree on one piece of legislation to send to President Barack Obama.

Last Wednesday the Senate approved a bill extending surface transportation authorization for 10 months, depositing $19.5 billion of general revenue into the Highway Trust Fund, and offering additional federal government support for states and localities who want to sell Build America Bonds to finance infrastructure projects.  The House of Representatives responded on Thursday by passing a separate bill that would, among other provisions, extend surface transportation authorization for only one month and not include any additional transportation funding or bonds support.

Senate Democratic leaders kept the chamber in session until near midnight late Thursday night attempting to gain approval of the House's one-month extension bill.  However, Sen. Jim Bunning, R-KY, continued objecting to multiple requests to adopt the legislation by unanimous consent.  Under Senate rules, all senators must concur to passing a bill without a formal debate or vote.  Senate Majority Leader Harry Reid, D-NV, said Bunning was the only senator who refused to agree to allow the bill to pass to buy Congress an additional month to work out an agreement on a longer-term extension.

Bunning said he objected because the extensions were not paid for. He proposed covering the bill's $10.3 billion cost by rescinding unobligated balances from the recovery act, an amendment Reid declined to accept.

"I'll be here as long as you're here and as long as all those other senators are here and I'm going to object every time because you won't pay for this and you propose never to pay for it," Bunning said Thursday night.  "We have a debt of $14 trillion.  We can't sustain it."

Senate Majority Whip Dick Durbin, D-IL, brought up the House measure again Friday morning but Bunning reiterated his objection.  The Senate then adjourned at 11:40 a.m. and will meet again Monday, with no votes scheduled until Tuesday.  The House did not bring up the Senate's version of a 10-month extension today after a disagreement among Democrats regarding several provisions meant passage was unlikely if a vote had been called.  The House adjourned at 1:36 this afternoon and will meet again Tuesday.

As Congress left town for the weekend without extending the legal authority for operations of the Highway Trust Fund, the repercussions will be felt immediately in the early hours Monday as the Federal Highway Administration initiates shutdown procedures.  No payments to states or transit authorities can be made after Sunday until a new law is enacted providing authority for such expenditures.

Oberstar told reporters Friday afternoon that he has reached a deal with Reid and House Speaker Nancy Pelosi, D-CA, to move forward with the Senate version of an extension next week.  Under the agreement, Oberstar said the House would accept the Senate's language as is but the Senate would then follow up by passing a revised highway discretionary formula that the House could also approve and send to Obama.  Oberstar said that should happen sometime later next month.

Furloughs Expected to Begin Tuesday; Impacts of Shutdown Already Hitting States

Administrative expenses from the trust fund can be paid for 24 hours after a shutdown, meaning federal employees whose salaries are paid from the Highway Trust Fund can report for work Monday to have one day to shut down their operations.  Most employees from the Federal Highway Administration, the Federal Motor Carrier Safety Administration, the National Highway Traffic Safety Administration, and the Research and Innovative Technology Administration -- some 4,000 U.S. DOT workers in total -- will be barred from coming to work effective Tuesday since no legal authority for their salaries will exist.  Only select employees deemed "essential," high-ranking officials appointed by the president and some NHTSA and RITA employees paid out of the government's General Fund, will be able to report for work Tuesday.

FHWA averages $154 million in daily payments to states, Oberstar said, while the Federal Transit Administration averages $31 million, NHTSA averages $3 million, and FMCSA averages $2 million.  Those payments will all be suspended effective Monday.

However, collection of the 18.4-cent-per-gallon federal gasoline tax and 24.4-cent-per-gallon federal diesel tax -- the primary revenue sources for the Highway Trust Fund -- will continue because the U.S. Treasury Department has separate authority to collect those highway user fees, Oberstar said.

This is believed to be the first time since the Highway Trust Fund was created in 1956 that its legal authority will lapse.  Most of the federal government was closed from Nov. 13-19, 1995, and from Dec. 15, 1995, to Jan. 6, 1996, during budget disputes that left them without appropriations.  However, U.S. DOT was largely unaffected by the government shutdowns then because the department's appropriations bill was signed into law Nov. 15, 1995.

With continued uncertainty about federal funding levels for highway and bridge projects, state transportation departments are already feeling the effects.

CARB Update!!
 
Off-Road Diesel
 
On Friday, February 26 the California Air Resources Board (CARB) issued an advisory on the Off-Road Regulation.  With this, CARB addresses some of the issues and questions raised about how CARB intends to move forward with enforcement of the regulation until such time the US EPA approves the air board's request for a waiver to regulate off-road engines.  A copy of the advisory can be obtained here.

The advisory states, in part, that “because of the continuing effects of the economy on industries that use off-road diesel vehicles, in particular the construction industry, and because ARB currently lacks authorization from the United States Environmental Protection Agency to enforce certain aspects of the regulation, effective immediately, no enforcement action will be taken for noncompliance with the specific provisions of the regulation described in Item I below.  In addition, during this enforcement delay, fleets will not be retroactively cited for noncompliance with these provisions. This enforcement delay will remain in place until U.S. EPA grants authorization to California to enforce all provisions of the regulation. At that time, ARB will provide fleets with up to an additional 6 months to comply with all requirements, as we’ve done previously with other regulations.”

Please be advised that many provisions in the regulation remain in effect and are not subject to this enforcement delay.  A more detailed description of the overall requirements of the regulation is provided in the advisory.  A copy of the advisory can be obtained here

REMINDER!!

As reported in the February 15, 2010 APACA Newsletter, CARB has scheduled a hearing on March 11, 2010 in Sacramento for contractors and other stakeholders to testify on the question of whether the Off-road Regulation should be further modified due to the down economy and subsequent emission reductions.  For those interested and impacted by this regulation you need to plan on attending this important hearing!  If you cannot go, please send your comments to the APACA office so that we can pass the message along to CARB.

CARB needs to hear how the economic recession has affected your company. The information that can help demonstrate this includes:
A comparison of company data from 2006 to 2010, including:
 - Number of Employees
 - Revenue
 - Size of Fleet
 - Bonding Capacity
 - Ability to Finance/Borrow
 - Fuel Consumption/Idled or Parked Equipment/Emissions
What has your company done to comply with the regulation already:
 - Retrofits installed
 - Engine Repowers
 - Purchased New Equipment
 - Sold Equipment
What are your company’s future plans to achieve compliance in the next two, three years:
 - Further Shrinkage of Fleet and Employees
 - Close Business
 - How will this affect your company’s Project Capacity
 - When do you anticipate the construction industry will recovery from the recession?
 
For additional information, please contact the APA of California office at 949-855-6489.

Warm Mix Asphalt ? What?
 
Last week we discussed the “WHY” of warm mix asphalt (WMA):  the environmental and economic driving forces ? reduced fumes, emissions and energy consumption.  This week it’s “WHAT is WMA?”  Quite simply, WMA is the generic term used to describe technologies that allow a 30°F to 100°F reduction in temperature for production, placement and compaction of asphalt mix.  These relatively new processes and products use various mechanical and chemical means to reduce the shear resistance of the mix at construction temperatures while reportedly maintaining or improving pavement performance.

The development of these technologies began in Europe with the German Bitumen Forum in 1997.  Shortly thereafter, the Kyoto agreement on green house gas reduction was adopted by the countries of the European Union.  Since then, a number of products and processes for HMA temperature reduction have been developed in both Europe and the United States.  In the interest of exploring the usefulness of these technologies, the National Asphalt Pavement Association (NAPA) began investigating them in 2002.  First, a contractor scanning tour of Europe was conducted where the processes and products currently used were demonstrated and discussed.  Next, representatives of European companies were invited to make presentations at the NAPA Annual Convention in 2003.  A demonstration project was constructed at the World of Asphalt Show and Conference in 2004.  In that same year, jointly funded research was initiated at the National Center for Asphalt Technology (NCAT) by NAPA, the Federal Highway Administration (FHWA), and some warm-mix technology suppliers on various methods for reducing asphalt mix production and placement temperatures.

Recent work funded through the Transportation Research Board indicates that there are currently 23 technologies available in the in the US, broadly categorized as follows:  organic additive or wax; chemical additive or surfactant; and foaming.  The WMA processes which use organic additives or waxes result in a decrease in viscosity when heated above the melting point of the wax, allowing mixing and coating.  Those processes using surfactants work through a variety of different chemical mechanisms.  The processes with water use the volume expansion from the conversion of liquid to gas/steam to cause an expansion of the asphalt binder and a resulting decrease in the mix viscosity.  The water can be introduced through a mechanical foaming operation or by the additional of a material containing internal water.  The choice of WMA process depends on several factors:  tons produced; capitol equipment costs; temperature reduction needed; and effect on PG binder.  Shown below is a summary of WMA technologies.


Next week we’ll highlight what’s happening…here and there.

The APA of Califorina is pleased to partner with the National Asphalt Pavement Association (NAPA) and the State Asphalt Pavement Associations (SAPA) on a series of educational webinars.  The following webinar is the first in the series for 2010. 
 
Thin Overlays for Pavement Preservation
NOTE: DUE TO EXTREME WEATHER, THE THIN OVERLAYS WEBINAR HAS BEEN RESCHEDULED FOR MARCH 2, 2010!
March 2, 1 PM Eastern
Presented by Dave Newcomb, Ph.D., P.E.
NAPA Vice President—Research and Technology
Thin asphalt overlays are the pavement preservation technique of choice by the majority of DOTs, according to AASHTO. Whether they are applied in conjunction with milling or placed on an existing asphalt surface, thin overlays offer better performance, enhanced ride quality, noise reduction, and reduced permeability at a cost that is lower than traditional asphalt overlays.

You will take away:

• How to appropriately select a thin overlay option
• How to select the materials and perform a mix design
• Production and construction techniques
• Performance expectations

This is a re-broadcast of NAPA's popular thin overlays webinar. A live question and answer session with Dave Newcomb will be included.

Price:
$75 for members and government officials
$150 for all others
