Tom Ewing’s Environmental Update

* Musical science: Harmony. On March 22 EPA and DOT announced reconsideration of the mid-term evaluation of greenhouse gas emissions standards for model year 2022-2025 light duty vehicles. EPA regulates GHG. But DOT’s National Highway Traffic Safety Administration sets fuel economy standards. EPA finished its work and, in January, unilaterally set new fuel standards since that’s really the only way (right now) to control GHG. However, NHTSA’s evaluation was not ready and it pushed back. EPA’s GHG review is supposed to evaluate impact on fuel economy and “a national harmonized program.” EPA, naturally, wanted the solo part. Now a new choral directed yanked ‘em off stage, so to speak. A review will restart. EPA’s new Final Determination is due no later than April 1, 2018, likely to be arranged as a duet or maybe even an ensemble. You can be sure those engines will be purring with complex harmonies…

* DOE’s Electricity Advisory Committee meets this week in Arlington, VA. The agenda covers a range of issues critical for the critical changes that electricity planners say are required to transition the US from old-school power systems to an integrated system able to move almost as fast as the electrons themselves, and provide enough power for the transportation sector. The Internet of Things is a central agenda item – there are a lot of things that use electricity. Other topics focus on smart grids, power delivery, storage and presentation of MIT’s Utility of the Future Study.

* Colonialism. Energy agencies in California released a final Renewable Energy Transmission Initiative report last month. It’s a difficult read (mostly because it’s written in the docu-speak language) but it is chock full of important information. Transmission is a critical concern, such as a California “intertie” to wind projects in Wyoming and New Mexico! (What if Chicago, about equidistant, wants Wyoming’s wind power?) Meanwhile, while donor states get spiked and laced with oh-so-scenic generation and transmission infrastructure the report also tells of local prohibitions on renewable energy in San Bernardino, Los Angeles and Solano Counties, the CA end-points sucking up the energy produced 1000 miles away! What?

ASCE Takes Report Card Grades and Solutions to Lieutenant Governors

How bad is our infrastructure? Probably worse than you ever imagined. The American Society of Civil Engineers (ASCE) has prepared an Infrastructure Report Card that details the problems the country faces with updating, restoring, improving and making our infrastructure safe with a state-by-state overview. (See link below) The association has been doing an infrastructure report card for some time and has provided the country with a realistic and serious look at the things we all take for granted,  our roads and bridges topping the list. Take the time to review the condition of your state’s infrastructure so that you can support efforts made to improve it.
ASCE participated last week in the National Lt. Governors Association annual State-Federal Relations meeting in Washington, DC. The seconds-in-command of the states and territories gathered in Washington D.C. March 15, 2017, to work on schools, roads, and more. Casey Dinges was on the agenda to talk to the Lt. Governors about the solutions offered in the 2017 Infrastructure Report Card. The meeting also focused on ideas on how to streamline state regulations, preserve international markets for agriculture, and assist veterans with health issues.

NAPA Reports: Survey Documents Sustainability of Asphalt Pavements

Nationwide, More Than 77.2 Million Tons of Recycled Materials Used in Asphalt Pavements; One-Third of Asphalt Pavements Produced as Warm Mix

The latest survey of asphalt pavement mix producers documents the industry’s continued success in improving the sustainability of America’s roads through the incorporation of recycled materials and the use of energy-saving warm-mix asphalt technologies.

According to the latest survey of asphalt mix producers conducted by the National Asphalt Pavement Association (NAPA) in partnership with the Federal Highway Administration (FHWA), more than 77.2 million tons of recycled materials — primarily asphalt pavement material reclaimed from old roads and parking lots and recycled asphalt roofing shingles — was used in new asphalt pavement mixtures during the 2015 construction season. In addition, nearly a third (32.8 percent) of all asphalt pavement mixture was produced that year at reduced temperatures using warm-mix asphalt technologies.

The survey has gathered annual data from asphalt pavement mix producers and state asphalt pavement associations since 2009. Over that time, it has documented growth in the use of both warm-mix technologies and recycled materials in pavement mixtures. For the 2015 construction season, the survey was extensively revised to collect additional information about how reclaimed asphalt pavement and shingles are used nationwide.

“Asphalt pavements are already recycled at a greater rate than any other material,” stated Dan Gallagher, 2017 NAPA Chairman and Vice President of Gallagher Asphalt Corp. of Thornton, Illinois, “but we are not content with that. We continue to seek out and put to use practices and technologies that deliver high-performing roads, both in terms of drivability and sustainability.”

The survey found that more than 74 million tons of reclaimed asphalt pavement (RAP) and 1.9 million tons of reclaimed asphalt shingles (RAS) were used in new asphalt pavement mixes in the United States during 2015. An additional 7 million tons of RAP were used as aggregate, cold mix, and other road-building activities. The survey also found that at year-end 2015 about 85 million tons of RAP was stockpiled for future use across the country.
Reclaiming and reusing the asphalt cement and aggregate in RAP and RAS saved about $2.6 billion in 2015 compared to the use of virgin asphalt binder and aggregates. This helps keep asphalt pavement mixture costs competitive and allows road owners to achieve more roadway maintenance and construction activities with limited budgets.

Producers were also asked about ground tire rubber, steel and blast furnace slags, and other waste materials repurposed into pavements. Although national estimates of their usage were not calculated, respondents reported using more than 1.1 million tons of these materials in 2015 in the production of about 8 million tons of asphalt pavement mixes.

In addition to increased use of recycled materials, asphalt mix producers continue to increase the use of energy-saving warm-mix asphalt technologies. In 2015, 119.8 million tons of warm-mix asphalt was produced — nearly one-third of total asphalt pavement mix production. This is a 5 percent increase from 2014 and a greater than 614 percent increase in the use of warm mix since 2009, the first year the survey was conducted.

Warm-mix asphalt is produced with a range of technologies that reduce the production and placement temperature of asphalt pavement mixtures. A variety of environmental, worker safety, and construction benefits have been realized through the adoption of warm-mix asphalt. In 2009, FHWA selected warm-mix asphalt as one of the first technologies targeted for deployment through its Every Day Counts initiative.

“The use of warm-mix asphalt technologies is becoming commonplace. In 14 states, more than half of all asphalt pavement mixtures were produced as warm-mix asphalt, and in four of them, more than 75 percent was produced as warm mix,” stated NAPA President Mike Acott. “This said, there is room to increase its use, and we expect road owners to continue to embrace these technologies for their construction and performance benefits, as well as the energy savings they bring.”

The survey was conducted in 2016. Results from 214 companies with 1,119 plants in 48 states and Puerto Rico, along with data from state asphalt pavement associations for 33 states, were used to compile the report. A copy of the full survey report, including a state-by-state breakdown of data, is available at www.asphaltpavement.org/recycling.

About the National Asphalt Pavement Association
The National Asphalt Pavement Association (NAPA) is the only trade association that exclusively represents the interests of the asphalt producer/contractor on the national level with Congress, government agencies, and other national trade and business organizations. NAPA supports an active research program designed to improve the quality of asphalt pavements and paving techniques used in the construction of roads, streets, highways, parking lots, airports, and environmental and recreational facilities. The association provides technical, educational, and marketing materials and information to its members; supplies product information to users and specifiers of paving materials; and conducts training courses. The association, which counts more than 1,100 companies as members, was founded in 1955.

ABC Says Construction Unemployment Rates Improve in 10 States Year-Over-Year

Construction unemployment rates were down in 10 states and unchanged in three in January on a year-over-year basis, according to analysis released today by Associated Builders and Contractors (ABC). For the nation and 37 states, rates were higher than in January 2016, ending 75 consecutive months of year-over-year declines. The national not seasonally adjusted (NSA) construction unemployment rate of 9.4 percent was up 0.9 percent from January 2016, according to data from the U.S. Bureau of Labor Statistics (BLS).

Since these industry-specific rates are NSA, it is most accurate to evaluate the national and state-level unemployment rates on a year-over-year basis.

“It was inevitable that the remarkable ongoing streak of year-over-year declines in the national unemployment rate would come to an end at some point,” said Bernard M. Markstein, Ph.D., president and chief economist of Markstein Advisors, who conducted the analysis for ABC. “The halt to this record may be largely due to the mounting shortage of skilled construction workers acting as a drag on the ability of the sector to grow. Despite this challenge, construction activity will continue to advance this year.”

In spite of the year-over-year rise, this was the second lowest national January NSA construction unemployment rate since January 2007 when the rate was 8.9 percent. Meanwhile, BLS data showed that the industry employed 162,000 more workers than in January 2016.

The usual pattern in the movement in the national NSA construction unemployment rate from December to January is an increase. Starting in 2000, when the BLS data for this series begins, the January rate has risen every year. This year’s 2 percent rate increase was no exception.

View states ranked by their construction unemployment rate, their year-over-year improvement in construction unemployment, their monthly improvement in construction unemployment, a regional breakdown of states’ construction unemployment rates and their January unemployment rates for all industries.

The Top Five States
The states with the lowest estimated NSA construction unemployment rates in order from lowest rate to highest were:

1. Hawaii
2. Utah and Virginia (tie)
4. South Carolina
5. Texas

Only one state, Hawaii, was also among the top five in December. Hawaii had the lowest rate among the states, with a 6 percent estimated construction unemployment rate unchanged from January 2016 and the state’s lowest January rate since the 5.1 percent rate in January 2006.

Utah and Virginia, with a 6.3 percent construction unemployment rate, tied for the second lowest rate in January. This was a big jump for Utah, which was also one of the 10 states that experienced a year-over-year drop in its rate, and marked the seventh year in a row that its January rate was down from the year before. For Virginia, the January 2017 rate was the state’s second lowest estimated January rate since the 6.2 percent rate in 2007, behind January 2016’s industry unemployment rate of 5.8 percent.

South Carolina, with the fourth construction unemployment rate lowest rate (6.4 percent), recorded its second lowest January rate, after last January’s 6.2 percent, going back to the beginning of the January estimates in 2000. Texas recorded the fifth lowest rate at 6.6 percent, despite having the seventh largest year-over-year increase in its rate among the states, up 1.5 percent.

The Bottom Five States

The states with the highest NSA construction unemployment rates in order from lowest to highest rates were:

46. Montana
47. Illinois
48. Rhode Island
49. West Virginia
50. Alaska

Four of these states—Alaska, Illinois, Montana and West Virginia—were also among the five states with the highest construction unemployment rates in December. Alaska recorded the highest estimated NSA construction unemployment rate for the fourth month in a row at 22.5 percent. This is to be expected since these are NSA construction unemployment rates; however, the state also had the largest year-over-year increase in its rate at 4.7 percent.

West Virginia had the second highest construction unemployment rate in January (16.4 percent) and its 5.5 percent increase from December was the second largest among the states behind Rhode Island’s 6.5 percent increase.

Rhode Island had the third highest estimated NSA construction unemployment rate in January (16.3 percent); however, it was among the 10 states with a drop in its year-over-year rate (down 0.3 percent) and the state’s lowest estimated January rate since the 11.3 percent rate in January 2007.

Illinois had the fourth highest rate in January, 15.8 percent after recording the third highest rate in December, and Montana had the fifth highest construction unemployment rate in January (15.3 percent), but was among the 10 states with a drop in its year-over-year rate (down 0.3 percent).

Note on Data Revision
On March 13, the Bureau of Labor Statistics (BLS) released its benchmark revision of state employment data covering the period from April 2015 through December 2016 (some data prior to April 2015 were also revised). The models used to estimate state construction unemployment rates were updated incorporating the new data. The revised data and the updated models resulted in some changes to the previously estimated state unemployment rates. Read more on the impact of the revisions on previous construction industry unemployment rate estimates on ABC’s website.
