Dig It: Rethinking how we Manage Soil at Redevelopment Sites

by Martha Faust and Sarah Sieloff (Center for Creative Land Recycling)

When is soil just “dirt”, when is it a waste, and when is it a resource? The answer may be in the eye of the beholder. Given the length of time it takes to create 1 cm3 of topsoil (estimated at 200-400 years), the current approach to managing excess soil at redevelopment sites in the United State (U.S.) merits further analysis.

Following passage of the 1980 Federal Superfund law, states, localities, and the real estate sector began considering the redevelopment potential of sites with environmental histories that were below the Superfund threshold. In 1988, the Minnesota Legislature amended the state Superfund law, creating the country’s first voluntary investigation and cleanup program, initially called the Property Transfer Program. The Property Transfer Program’s purpose was to review and approve investigation reports and response actions plans prepared by voluntary parties, and provide assurance letters to help facilitate real estate transactions. In those early days, response actions focused on excavating and disposing of contaminated fill soils. Applying cost-benefit analysis to “dig and dump” practice was not a key consideration. Success was determined by helping otherwise unmarketable properties move forward.

Fast forward to today, and we are truly living in different times. Around the world and across the country, governments have recognized the need for next-generation thinking about how we manage excess soils. New considerations include cost savings, efficiency, the advent of risk-based site cleanups, what constitutes a solid waste, as well as sustainability, resilience and climate adaptation. Factor in scarce public resources to fund redevelopment, and the need to take a fresh look at current practices is obvious.

The Center for Creative Land Recycling and Minnesota Brownfields recently teamed up to present two webinars showcasing the latest innovations in managing excess soil.  The first session covered the United Kingdom’s (U.K.’s) approach to excess soils management. Sustainability considerations, as well as diminishing landfill space and sharp increases in tipping fees, led to governmental rule changes and the creation of CL:aire, a national clearinghouse in England and Wales for the exchange of both regulated and unregulated materials. CL:aire oversees a system for matching receiving and importing sites, following a Definition of Waste Code of Practice (DoW CoP). The DoW CoP enables the reuse of excavated materials on-site or their movement between sites. Since launching in 2008, the DoW CoP has resulted in nearly 3300 “declarations” or projects, and has diverted 56,106,448m3 from landfills— enough to fill over 22,000 Olympic swimming pools. Following the U.K. government’s lead, the redevelopment industry was crucial to informing and developing the DoW CoP. As a non-governmental organization, CL:aire is responsible for logistics, tracking, and quality control of professionals, providing a comprehensive system that is well beyond the capacity of most governments. It is true that liability is a far less prevalent concern in the U.K. than in the U.S. Nonetheless, U.S. governments seeking new approaches to excess soil management will find they can learn much from the CL:aire system.

The second webinar examined newer models around the U.S. for excess soil management. In 2017, the New York Department of Environmental Conservation implemented Part 360 rule changes, ending the classification of fill soils as a solid waste subject to four conditions, and providing non-landfill options for reuse of fill soils. The Minnesota Pollution Control Agency is currently exploring modifying state statute to enable liability protection for exporters and importers of regulated fill soils. The Ohio Environmental Protection Agency (EPA) has teamed up with the U.S. EPA’s Cleveland office to implement beneficial reuse of dredged material at eight federally operated ports, using a process to repurpose the dredged materials for agricultural uses. And in New York City, the Office of Environmental Remediation’s Clean Soil Bank is a municipal soil exchange connecting clean fill to a variety of end uses and users, including parks and climate resilience waterfront projects. In so doing, the Clean Soil Bank has produced significant project cost savings and environmental benefits. Did you miss either or both of these webinars? Not to worry: the Center for Creative Land Recycling has you covered with slideshows and recordings.

Together, these webinars show how governments are adapting soil management rules and policy to respond to changing conditions. Cities and states are facing new challenges:  deteriorating infrastructure and diminishing landfill space; environmental justice concerns; cost efficiency; public health considerations; truck emissions; climate resilience and sustainability are all influencing the current debate. So again, we ask: when is soil just “dirt”, when is it a waste, and when is it a resource? In answering this question, one thing is certain: the rules and policies of 30 years ago are no longer sufficient to respond to current redevelopment needs.

2017 EPA National Brownfields Leadership Conference Recap

The 2017 EPA National Brownfields Training Conference is officially in the books. From December 4 through December 7, Minnesota Brownfields staff were in Pittsburgh at the EPA’s flagship conference for brownfields professionals. The bi-annual get together served as a tremendous opportunity to share best practices and new ideas.

A major theme that resonated throughout the conference was that there is a determined spirit shared across the country to continue pushing forward for brownfield redevelopment. There were plenty of opportunities to celebrate the amazing work that has already been done, but there was also an understanding that there is still much work to do.

Keynote speakers for the conference, Dan French of Brownfield Listings and John Paul Farmer of Microsoft, both detailed how the brownfields community is interconnected to the greater economy and society. Brownfield redevelopments are projects that impact everyone and are symbols of progress and rebuilding. As a piece of the bigger picture, brownfields serve as a spark for innovation, collaboration, and new opportunities.

Here are some major highlights of the conference from Minnesota Brownfields:

  • The biggest thrill of the week was that Minnesota Brownfields hosted a panel presentation titled “Dig It: Global Approaches to Contaminated Soil Reuse” with Nick Willenbrock of CL:AIRE, a United Kingdom NGO that operates a soil reuse system. Approximately 120 attendees came to the presentation to learn how CL:AIRE’s model for soil reuse was developed and implemented. A separate affiliate meeting followed the presentation where multiple states came to learn more. Minnesota Brownfields has worked closely with CL:AIRE over the last few years to advance the discussion of soil reuse in Minnesota. To be able to share this collaborative research with a national community was a prominent point in Minnesota Brownfields’ push to make soil reuse a reality in Minnesota.
  • Minnesota Brownfields also participated in multiple national affiliate meetings on the subject of public health and brownfields. The meetings, which were organized by the U.S. EPA, allowed Minnesota Brownfields to share the Brownfields Health Indicator Tool that was created in partnership with the Minnesota Department of Health. The tool was used in a pilot project in the City of Duluth. This was a tremendous opportunity to share the tool with a national audience.
  • Minnesota Brownfields made many connections with many other state and regional organizations that operate in a similar fashion. The list includes, the Brownfield Coalition of the Northeast, Center for Creative Land Recycling, Florida Brownfields Association, Georgia Brownfield Association, and the New York City Brownfield Partnership. There was also a meeting with representatives from the State of Kentucky that are interested in starting an organization similar to Minnesota Brownfields. We are excited for these relationships to grow.
  • A fun-filled evening was had at Minnesota Brownfields’ happy hour as well. Friends and colleagues, old and new alike, were able to connect and enjoy each other’s company while at the conference.

Now fully energized and motivated from the conference, Minnesota Brownfields is determined to continue our mission of promoting the sustainable reuse of contaminated land. Stay tuned as the new year approaches. We expect 2018 to be full of innovation and progress. Please consider joining us.

Forum – Institutional Controls: Everything You’ve Wanted to Know but Were Afraid to Ask

Institutional Controls or (“ICs”) are legal and administrative tools used at development sites to protect human health and the environment when contamination is left in place. Failure to understand how ICs work and how they are interlinked with all aspects of site reuse can lead to confusion and added time and cost to a project.
Attendees learned about the various types of ICs, when and how they are used, their benefits and limitations, current complexities, and how to balance opportunities for future site reuse with environmental protection.

The Future is Bright for Solar Energy on Capped Landfills

Solar energy production has taken off in Minnesota over the past few years, and especially in the last handful of months. In 2017, according to the Minnesota Department of Commerce, the solar energy capacity has tripled in the state during the first quarter of the year. Currently, the energy capacity for solar in Minnesota is twelve times what it was in 2015. Community solar projects have been the main catalyst for Minnesota’s solar surge. The practice where multiple parties buy into an energy supply is attractive to many because it is a more manageable method of obtaining solar energy.

Landfills just may be another piece to the puzzle that helps Minnesota further increase solar energy production. Within the past year, landfills in Lake Elmo and St. Michael installed solar panels to assist in powering equipment that prevents the pollution of toxic gasses from the landfills. This is a practice used on capped landfills and the excess energy produced is then converted to the grid. In 2015, the city of Hutchinson unveiled the largest landfill solar project in Minnesota when 400 kw of ballasted racking mounted solar photovoltaic panels (PV) were installed on a capped landfill.

What solar energy projects need is suitable land that provides quality solar exposure. Capped landfills have the capability to provide land serviceable for (PV). A covered landfill is often not viable for commercial or industrial construction, but renewable energy is a useful alternative. Given that capped landfills tend to by flat and are mostly unhindered by surrounding trees or buildings, they provide optimal solar exposure. More often than not, landfills are located in areas with easy access for utilities and construction crews. Around the country, municipalities, utilities, and landfill owners have found that solar can be the ideal fit for capped landfills. The limited uses in repurposing can provide new economic generation for the site.

There are certain characteristics that need to be in place for a closed landfill to be suitable for a solar energy system to be installed. A south facing landfill is the optimal direction in order to obtain the most solar throughout the course of the year, and having the landfill be tilted at the corresponding latitude. Also, the waste that is underneath the landfill cap will decompose and shift over time, which alters the landfill cap. Ballasted racking systems are the traditional solar installation needed for capped landfills so that the cap is not penetrated. Concrete blocks are positioned on the ground to allow for a structure to be built that holds the solar panels while not having to install anything below the surface of the ground.

Some new technologies are emerging that negate the use of ballasted racking systems for capped landfills. Hickory Ridge Landfill in Conley, GA is on the leading edge of landfill geomembrane solar cap technology. The landfill’s 45 acre geomembrane cap is covered with 7,000 PV rolls that covers 10 acres of the landfill cap. Overall this landfill produces 1 MW of energy that is sold back to a local utility. The benefits of the solar geomembrane cap are that the panels lie flat on the surface and it allows for shifts in the land composition below the cap itself. In addition, installation is easier than a ballasted racking system. Check out a video of the science behind the Hickory Ridge Landfill.

With there being limited options available for repurposing an old landfill, solar energy has emerged as an attractive option. Solar PV installation offers a new economic incentive and with developing solar technologies, such as the PV rolls used at the Hickory Ridge Landfill, landfill solar energy can become a feasible alternative for capped landfills in Minnesota and across the country.

Brownfield and Health Tool gives blighted sites across the state a healthy second chance

A new tool brings hope to some of Minnesota’s more than 10,000 former industrial or commercial sites that are underused or abandoned due to concerns about hazardous contaminants. Revitalizing these sites – called brownfields – can bring people and jobs back to areas, improve neighborhoods, help the environment and promote public health.

The City of Duluth is using the new Brownfield Health Indicator Tool to address the common challenges of transforming brownfields into productive community assets, including the complicated process of identifying and prioritizing redevelopment strategies that will best meet the long-term needs of the environment and community. The tool, developed in partnership with Minnesota Brownfields and the Minnesota Department of Health, aims to streamline project decision-making by focusing on health.

“From social cohesion to healthy housing to community service access, brownfield redevelopment provides an amazing opportunity to shape a wide range of factors that influence public health,” said James Kelly, environmental surveillance and assessment manager for the Minnesota Department of Health. “This tool was developed to help city planners, developers, institutions and communities across Minnesota understand these opportunities and uncover project strategies that are grounded in health equity. When you shape your process through the lens of health equity, benefits for the environment and economy will follow.”

Designed as a self-guided tool by those who influence and work on brownfield projects, the Brownfield Health Indicator Tool’s framework supports existing project decision-making processes. The tool can also help identify potential community health risks, assess the project’s proposed benefits, engage with project stakeholders and prioritize redevelopment strategies that provide multiple benefits.

Idle brownfield sites are often found in economically distressed areas, typically concentrated in urban locations, but they are also found in prime downtown and waterfront locations in nearly every community throughout the state. As abandoned sites, they disrupt ecological, economic and community connections. Revitalizing brownfield sites can offer an opportunity to bring people and jobs back to areas, resolve neighborhood blight, increase community connectivity, restore ecological balance and promote public health.

“Communities across Minnesota are looking for brownfield redevelopment best practices that balance the demands of economic growth with environmental and public health protection,” said Martha Faust, executive director of Minnesota Brownfields. “There are so many things to consider when redeveloping a brownfield site, which makes it difficult to organize and prioritize needs. Our partnerships at state and city levels have demonstrated that we can remove one of the process barriers in brownfield redevelopment by using this tool’s framework and by working on this together, we can better support the revitalization of Minnesota communities.”

The current City of Duluth Irving-Fairmount Brownfields Revitalization Plan draft draws guidance from the Brownfield Health Indicator Tool, specifically in the areas of social cohesion (integrating a neighborhood gathering space), connectivity (new pedestrian trail and improved truck circulation) and economic stability (land redevelopment for both economic development and housing). Health equity and well-being are also core principles, tied to the Imagine Duluth 2035 comprehensive planning process.

“Brownfield redevelopment is all about a do-over,” said Heidi Timm-Bijold, business resources manager for the City of Duluth. “This tool has been a critical asset in making the most of our second chance in the Irving and Fairmount neighborhoods by helping us all better understand, prioritize and elevate what health means for this community and what opportunities this redevelopment offers. By engaging the community and our research team with this tool, we were able to articulate core values for the project that we might have missed otherwise.”

Integrating the tool into their brownfield redevelopment process represents one step in the journey of leveraging brownfields as catalysts for healthy change in the City of Duluth. The city plans to take learnings from this pilot project and use them as a springboard for shaping future redevelopment efforts as it maps out land use for the Imagine Duluth 2035 comprehensive plan.

To access the Brownfield Health Indicator Tool, visit Brownfield Health Indicator Tool or Brownfields and Public Health.

The City of Duluth project is funded by a U.S. Environmental Protection Agency Area-Wide Planning Grant, which provides funding to communities to research, plan and develop implementation strategies for cleaning up and revitalizing a specific area affected by one or more brownfield sites.

Can you dig it? Minnesota looks at potential for greater reuse of regulated fill soils.

States around the U.S. have different regulations governing how regulated (contaminated) fill soils at redevelopment sites are managed, and whether they can be reused. The most common practice is what’s called “dig and dump”, or excavating soils with contaminant concentrations in exceedance of permitted levels, then hauling those soils to an area landfill to use as daily cover. Problem solved, right? Turns out, not exactly.

Hauling regulated soil to landfills is expensive. For many Minnesota metro-area redevelopment projects receiving brownfield grant funds, up to 100% of grant funding is sometimes used just for dig and dump. Given that most brownfield grant programs are oversubscribed, this is concerning. Furthermore, trucks transporting the fill soils to often remote landfills result in additional vehicle miles traveled. Elsewhere around the world, countries like Great Britain are at or nearing landfill capacity and have had to find other solutions to this problem. Meanwhile, in Minnesota there are redevelopment projects occurring in close proximity where Site A has excess soils, and Site B requires additional soils. Depending on the characteristics of the fill soils, there is the hypothetical possibility to transfer regulated soils between the sites. There could be tremendous cost savings and reduced truck traffic realized in such a scenario.

Minnesota Brownfields has studied current redevelopment practices to measure the economic and environmental cost of dig and dump. Since 2015, Minnesota Brownfields has been meeting regularly with the Minnesota Pollution Control Agency (MPCA) to consider policy revisions to allow regulated fill reuse at redevelopment sites, if certain conditions are met to ensure protection of human health and the environment. Those who work in redevelopment know that MPCA already has a policy in place to enable regulated fill reuse. Without liability protection, the policy — though well-intended — just hasn’t been used. So the current discussion is focused on providing liability protection for both the exporting and importing site. While we aren’t there yet, a change to MN Statutes is being considered to address this issue.

Want to learn more? Read more about our soil reuse study here. Or join us on Tuesday, July 18 at the State of Brownfields Update in Minneapolis, where Amy Hadiaris of MPCA and attorney Sara Peterson will present potential policy and changes. To learn more about how soil reuse works elsewhere in the world, attend the EPA Brownfields Conference December 5-7 in Pittsburgh, where Sara Peterson will moderate a panel discussion with representatives from the United Kingdom and Province of Ontario.

Community Conversations: West Side Flats Greenway

On Tuesday, the first community meeting for the West Side Flats Greenway took place at the Neighborhood House/Wellstone Center in St. Paul. Attendees were greeted by project members and asked to participate in a number of activities relevant to the planning process. People were asked to write about what they saw for the space in ten years and to vote on their ideal space designs. With this process there were pictures of various gathering space concepts, water features, park types, bench styles, and activities displayed where each person voted for their two favorites in each category.

The theme of community input was apparent throughout the meeting and was especially salient because the green space is all about designing for function and amenity.

The West Side Flats Study Area is approximately 120 acres and is located directly across the Mississippi River from downtown Saint Paul; situated between the river, Plato Boulevard, Wabasha Street, and Lafayette Road. The proposed Greenway is located along a working rail line that divides the Study Area.

The Study Area was funded through multiple grants including U.S. EPA Brownfields Areawide Planning. Through this grant, Minnesota Brownfields was brought on as a partner to help inform the community about the role of brownfields in redevelopment planning for the West Side Flats. The Areawide grant  enables planners to assess not just the proposed study area but the area around it for an expanded, holistic, next-gen approach to planning. The site of the Greenway has soil contamination in the form of unregulated fill (cinders, brick, black top, and sand) which is not toxic along with a small area of arsenic cleanup.

Throughout the presentations there was a theme of returning back to the Flats as the immigrant population that once lived there was removed due to flooding. The vision for the West Side Flats is a mixed use urban village for all with the Greenway as the most prominent green space in the neighborhood. The Greenway will be part of a larger amenity complex with connections to a river walk and bike trails to make the park a multiuse amenity for residents.westsideflatsvote

However, there are a number of challenges that come with this project as well, the most important being the creative use of limited space. The area for the Greenway will not just be a park but a stormwater management site. There will be a stormwater pond to protect the area which is designed to withstand five year floods while also being a stormwater treatment area. Making this limited space a successful water management system and an appealing park able to support a large population is further compounded by the presence of the railroad and the existence of utilities that cannot be built on or have trees on as access is still needed. These challenges are daunting but involving community in the design process will help the community understand the process.

The West Side Flats Greenway is using a stacked-function green infrastructure concept where private property owners are partnering with the City of Saint Paul to use green design to manage stormwater runoff, reduce sewer overflows, and improve water quality. Barr Engineering is coordinating master planning for the stormwater functions of the Greenway. The City itself is implementing the process in a different way as the maintenance, operation, and assessment of the site is being done through multiple department partnerships instead of one department and is a learning process for all.

This meeting was all about helping the community understand the potential for the space along with the challenges that come along with it. Minnesota Brownfields was on hand to give insights into how projects like this have been handled in the past and what kinds of remediation need to be done at this area in particular. The next community meeting will be in 6 to 8 weeks where Barr Engineering will bring in proposals for the community to learn about and discuss.
