Center for Environmental Excellence Updating PAL Database

The American Association of State Highway and Transportation Officials Center for Environmental Excellence (CEE) is looking for state assistance in updating the contents of its Programmatic Agreement Library or PAL database.

The PAL database functions as a “central library” or “one-stop-shop” for programmatic agreements between state departments of transportation and/or the Federal Highway Administration in partnership with resource agencies that help streamline compliance with federal environmental laws such as the National Environmental Policy Act, the Endangered Species Act, and the National Historic Preservation Act.

The PAL contains not only the programmatic agreement information; it contains a link to the full agreement and provides on-going access for practitioners to research agreements that meet specific requirements.

However, most of the agreements within the database are 10 years old, so the CEE is asking states to review the documents within the PAL to see if they are still valid, need to be updated, or removed entirely.

State agencies willing to help review those PAL documents can contact the CEE at environment@aashto.org.

Video: Volunteers Help Oregon DOT with Wetland Renewal

Volunteers with Klamath Wingwatchers recently helped the Oregon Department of Transportation resettle “sedges” from the Lost River Wetlands to the Lake Ewauna Trail in Klamath Falls.

“Sedges” are grass-like plants with triangular stems and inconspicuous flowers that typically grow in moist, wet ground. They are a major – often the dominant – plant of many wetland ecosystems throughout the world and their long, strong densely tangled stems and roots can help with erosion control. They also help improve water quality by acting as filters to remove pollutants and sediments; demonstrating the ability to remove a large percentage of nitrogen and significantly sequester metals such as copper.

Colorado DOT Works to Minimize Monsoon Impact on Roadways

As state departments of transportation along the East Coast sharpen their disaster plans ahead of the peak point of the 2020 hurricane season – with mid-Atlantic and Northeastern state DOTs already grappling with flooding and high-wind damage cause by tropical storm Isaias – the Colorado Department of Transportation is deploying strategies to combat the summer monsoon season, which typically runs from mid-July until mid-September.

Monsoons – a term coined in the 19^th century by the British in India to describe the big seasonal winds and heavy rainfall coming from the Bay of Bengal and Arabian Sea – can create flash flooding, mudslides, and rock falls that can severely damage affect Colorado roadways; causing major dilemmas for the traveling public and Colorado DOT maintenance crews.

For example, a seven-day-long flood event in September 2013 left behind a path of destruction over an area of 2,380 square miles, causing $700 million in roadway damage. Colorado also endured a major rock fall event in 2016 during monsoon season that closed I-70 in the Glenwood Canyon for approximately two weeks.

Those events encouraged state officials to take a deeper look into improving the resilience of Colorado infrastructure. As a result, the Colorado DOT and the Colorado Division Office of Federal Highway Administration worked to develop a plan to proactively identify and address vulnerabilities of the state’s roadway system to threats like flooding and landslides.

As a part of that plan, the two agencies kick-started the I-70 Risk and Resilience or R&R pilot project August 2016; examining 450 miles of I-70 from the Utah border in the west to the Kansas border to identify the potential for future damage and roadway closures due to extreme weather-related events such as monsoons.

The R&R pilot project – completed in the fall 2017 – provided risk and resilience information for assets along I-70 and helped the Colorado DOT prioritize work at key locations where risk is high and resiliency is currently low.

One of the areas identified as an important risk factor to road closures was culvert risk mitigation planning. Lizzie Kemp, Colorado DOT’s resiliency program manager, said that the study found flooding is the largest corridor risk when looking at user costs due to delays, with 80 percent of that risk due to minor culvert failure.

She noted that Colorado has nearly 60,000 culverts that fall into this “minor” category – under 4 feet long – and so the agency first prioritized repairing and/or replacing such culverts found in poor condition along critical routes. To help with that prioritization effort, the agency uses a Geographical Information System or GIS-based Culvert Risk Assessment tool (created by Gerry Shisler for the Colorado DOT) that takes data available statewide and uses it to identify culverts, their condition, and whether they are located on “critical” roadways.

The Colorado DOT found approximately 1,000 culverts across the state were in poor condition on critical routes and the agency than used that information to development and implement a three-step mitigation plan:

Step 1: Maintenance patrols complete an inspection of identified high-risk culverts and update the condition in the minor culvert database tool.
Step 2: Identify and document specific proposed mitigation actions for each culvert based on inspection, which could include replacing the culvert or making minor repairs.
Step 3: If replacement or repair is too costly or not possible, identify and document a specific operations plan which may include increased cleanout frequency and installation of technology to monitor hydraulic flows.

The Colorado DOT also found that minor culvert damage caused more than $94 million to roadway users from delays on the I-70 corridor alone; representing 80 percent of all user costs due to flooding. As a result, the agency expects that preventing minor culvert failure during monsoon flooding events should save hundreds of millions in highway user delay costs across the state.

Caltrans Repaves Road with Completely Recycled Material

The California Department of Transportation recently repaved a three-lane, 1,000-foot long section of Highway 162 using recycled asphalt pavement and liquid plastic made with single-use, plastic bottles – the first time the department said it has paved a road using 100 percent recycled materials.

The agency noted that such “plastic” roadways in previous test projects were found to be more durable and last two to three times longer than traditional hot-mixed asphalt pavement.

Using new technology developed by TechniSoil Industrial of Redding, CA, a recycling train of equipment grinds up the top three inches of pavement and then mixes the grindings with a liquid plastic polymer binder that comes from a high amount of recycled, single-use bottles. The new asphalt material is then placed on the top surface of the roadway, eliminating the need for trucks to bring in outside material for a paving operation. By eliminating the need to haul asphalt from the outside, this process can also help cut greenhouse gas emissions.

“This pilot project underscores the department’s commitment to embracing innovative and cost-effective technologies while advancing sustainability and environmental protection efforts,” noted Toks Omishakin, director of Caltrans, in a statement.

“Using waste plastic that was otherwise destined for a landfill will not only reduce the cost of road repair and construction, but also increase the strength and durability of our roads,” added California State Senator Ben Hueso, who has advocated that Caltrans test this material. “California is uniquely positioned to transform the transportation industry once again by using this new technology that could revolutionize the way we look at recycled plastic.”

Caltrans noted currently has a cold in-place asphalt recycling program that uses large machines to remove three to six inches of roadway surface and grind up the asphalt while mixing it with a foamed binding agent made of bitumen, a leftover sludge from oil refining. However, that recycled material used in this process is only durable enough to serve as the roadway base – and trucks must deliver hot-mix asphalt from a production plant located miles away and place a final layer over that base.

That’s why Amarjeet Benipal, director of Caltrans’ District 3, said the new plastic roadway process is better for the environment versus the cold in-place program. “It keeps plastic bottles out of landfills and helps reduce greenhouse gas emissions and reliance on fossil fuels,” he noted.

Several state DOTs are testing a variety of different products to help make roadway pavements more durable and environmentally-friendly.

The Minnesota Department of Transportation, for example, began testing a new asphalt additive along with two private companies in late 2018 along a stretch of Interstate 94 outside Albertville, MN, near the MnROAD research facilities – an additive designed to help highway agencies and contractors use more recycled asphalt and less “virgin” products. That additives – called a “rejuvenator” and made by agricultural conglomerate Cargill and aggregate supplier Hardrives – is a substance that promises to reverse the effects of aging when the existing asphalt roadway is recycled back into the new road.

New California EV Rule Will Phase Out Diesel Trucks by 2045

The iconic image of a smoke-belching big rig growling down the highway will slowly fade into the California sunset, replaced by a smog-free electric vehicle (EV) gently humming down the road starting in 2024.

The California Air Resources Board unanimously approved the Advanced Clean Trucks regulation that requires manufacturers to begin transitioning from diesel trucks and vans to electric zero-emission trucks in 2024. By 2035, at least 40 percent of truck manufacturers’ sales would have to be EV trucks, and every new medium-duty and heavy-duty truck sold in the state would be a zero-emission vehicle by 2045.

The goal of the ruling is to reduce air pollution and help California meet federal air quality standards, “especially in the Los Angeles region and the San Joaquin Valley – areas that suffer the highest levels of air pollution in the nation,” according to a CARB news release.

Although trucking interests were mixed in their opinions of the new rule, environmental groups hailed it as a historic moment. The Sierra Club California said the ruling is “a win for the environment, air quality and the economy” and predicted it will “ensure a steady supply of zero-emission trucks.”

Whether it will ensure a steady supply of funding for Caltrans remains to be seen.

Although California leads the nation in EV ownership, EV owners do not pay fuel taxes – a main funding source for Caltrans and other state DOTs across the country. A new registration fee for model year 2020 and newer EVs is only projected to bring in $10.9 million this year, according to the 2020-2021 Caltrans budget.

However, agency officials added that another new fee – an annual assessment of up to $175 per EV – should bring total EV fees up to $50 billion over the next 10 years, with proceeds from EV registration and annual fees helping to pay for infrastructure projects.

By contrast, the 2020-2021 combined diesel excise and sales tax revenues are expected to bring Caltrans $2.2 billion – a number that will surely drop as diesel trucks fade away.

A similar “action plan” is to support broader deployment of EVs is being developed by 15 states and the District of Columbia. It aims to ramp up electrification of medium- and heavy-duty vehicles, including large pickup trucks and vans, delivery trucks, box trucks, school and transit buses and long-haul delivery trucks. In a joint memorandum of understanding issued in mid-July, that coalition aims to ensure that 100 percent of all new medium- and heavy-duty vehicle sales be zero emission vehicles by 2050 with an interim target of 30 percent zero-emission vehicle sales in those vehicle categories of vehicles by 2030.

Minnesota DOT Releases Fourth Annual Sustainability Report

The Minnesota Department of Transportation recently released its fourth annual Sustainability Report; a 26-page document based on 2019 data that tracks the agency’s progress towards achieving a number of sustainability and climate goals.

Some of the sustainability achievements cited by the agency include: Reducing energy consumption per square foot by 17 percent between 2008 and 2019; issuing a request for proposal for community solar garden subscriptions that will save the Minnesota DOT more than $1.5 million and account for almost 25 percent of total agency electricity use; increasing the number of electric vehicles within the agency’s fleet from four to 29; exceeding the department’s goal in the 2018-2019 winter season for reducing salt usage.

[Margaret Anderson Kelliher, the Minnesota DOT commissioner and chair of the American Association of State Highway and Transportation Officials Committee on the Environment and Sustainability, recently explained Environmental Technical Assistance Program or ETAP podcast that Minnesota looks for the “triple bottom line” when evaluating sustainability: how sustainability efforts affect the health of people, how it impacts the environment, and how it impacts the economy.]

However, the Minnesota DOT also noted a few setbacks in its report as well. Carbon pollution from transportation, for example, continued to increase between 2018 and 2019 – an uptick attributed to low gas prices, increased freight traffic, people driving more miles, and more purchases of low-fuel efficiency pick-up trucks and sport utility vehicles. In addition, the agency reported higher fuel consumption by agency fleet vehicles in 2019, mostly by its snowplow trucks due to its winter operations needs

“Transportation is the primary source of carbon pollution in Minnesota and the U.S. and MnDOT is committed to address climate impacts and to work with communities throughout the state to develop a sustainable transportation system of the future,” emphasized Tim Sexton, the agency’s assistant commissioner and chief sustainability director, in a statement. The agency added that impacts to the state’s transportation system and its response to recent events in 2020 – including the COVID-19 pandemic and the civil unrest related to the killing of George Floyd in Minneapolis – may be addressed in future iterations of its sustainability report.

Toks Omishakin – executive director of the California Department of Transportation and chair of AASHTO’s Council on Active Transportation – will provide opening remarks for this webinar. His agency recently adopted an updated bicycle and pedestrian action plan that aims to reduce dependence on driving, promote safety, and reconnect communities that have been divided by freeways and high-speed roads. Caltrans said it developed that updated action plan in consultation with the California Walk/Bike Technical Advisory Committee with the goal of increasing bicycling, walking and transit trips.

Vermont Seeking Applications for Bicycle/Pedestrian Infrastructure Projects

The Vermont Agency of Transportation (VTrans) recently issued a grant solicitation for new infrastructure projects to improve statewide access and safety for bicyclists and pedestrians.

The agency noted that in 2019, it awarded a total of $3.6 million for construction and planning projects throughout Vermont via its Bicycle and Pedestrian grant program.

“These projects make it possible for more people to walk and bike safely in Vermont communities,” noted Joe Flynn, Vermont’s transportation secretary, in a statement.

“Municipalities across Vermont understand that providing good facilities for walking and bicycling are key factors for livability that can stimulate economic development in our downtowns and improve public health,” he said. “In light of the current pandemic, providing safe ways for Vermonters to walk and bike is especially important. Supporting our downtowns is critical in helping jumpstart our economy.”

Flynn added that the goals for this VTrans grant program are to improve transportation options for commuters, visitors to the state, and recreational use. The agency also noted that Vermont ranks fourth in the nation for the percentage of commuters who bike or walk to work and fourth in per capita spending on bicycle/pedestrian projects, according to the 2018 benchmarking report on bicycling and walking in the United States issued by the League of American Bicyclists.
