ISTC Technical Assistance Program collaborates with Forest Preserves of Cook County on Clean Energy Framework

Forest Preserves of Cook County Clean Energy Framework cover

ISTC’s Technical Assistance Program (TAP) and the Forest Preserve District of Cook County (Forest Preserves) have a history of working together to improve sustainability. In 2014, the Forest Preserves, a public agency responsible for protecting and preserving nearly 70,000 acres of natural areas and public open space, engaged TAP to evaluate the current state of materials management operations, assess opportunities for improvement, and take steps toward making the Forest Preserves a national leader, among similar organizations, in waste reduction practices. The success of that project led the Forest Preserves to engage TAP to assist in developing and implementing their Sustainability and Climate Resiliency Plan, which was released in September 2018. That plan hinged upon an overall goal to reduce the Forest Preserves’ greenhouse gas (GHG) emissions by 80% by 2050 from a 2016 baseline. It also identified a road map for Forest Preserve lands to be resilient in a changing climate, recognizing that such conditions will significantly impact land management operations as the range and distribution of species shift, along with the availability of water and other key aspects of the local ecosystem.

On January 22, 2019, in response to a United Nations International Panel on Climate Change report, which demonstrated that the consequences of man-made climate change will become irreversible in 12 years if global carbon emissions are not immediately and dramatically reduced, the Forest Preserves of Cook County Board of Commissioners unanimously adopted a Net Zero Resolution. This resolution revised the 80% GHG emissions reduction goal to net-zero by 2050, as well as reducing facility GHG emissions by 45% by 2030 and committing to the development of a renewable energy plan. 

TAP is currently working with the Forest Preserves on updating their Sustainability & Climate Resiliency Plan accordingly, while simultaneously assisting with the implementation of previously identified objectives and strategies to achieve their ambitious GHG reduction goals.

The most recent result of this collaboration is the development of a Clean Energy Framework, modeled after the Cook County Energy Plan. The Forest Preserves of Cook County Clean Energy Framework documents existing conditions through a needs assessment and review of current initiatives. Further, it prioritizes renewable energy technologies and strategies which the Forest Preserves might employ and creates a roadmap to achieving the Forest Preserves’ 2030 and 2050 goals. A Net Zero Emissions implementation schedule is presented, and the relationships between the Clean Energy Framework objectives and the objectives of the broader Sustainability & Climate Resiliency Plan are outlined.

Within the Framework it is noted that to actualize the goals and strategies outlined, energy conservation and efficiency of the many existing facilities must be prioritized and continuously pursued to reduce the existing operational footprint of the Forest Preserves. On a parallel course, the concept of green building must be thoroughly explored, redefined, and codified to embody building operations, ecosystem services, and renewable energy generation, fully encompassing the Preserves’ values of environmental stewardship and fostering human well-being in any building upgrade or new building project. Simultaneously, the Forest Preserves must aggressively pursue vetting, selecting and ongoing implementation of on-site renewable energy systems, coupled with collaborative pursuit, in partnership with Cook County, of a large-scale renewable energy installation, and sourcing of RECs to account for any emissions balances.

Principal authors of the Framework include Anthony D. Tindall, Policy & Sustainability Manager of the Forest Preserves of Cook County, along with April Janssen Mahajan, Joy Scrogum, Savannah Feher, and Shantanu Pai of TAP. Jennifer Martin of TAP was also among the advisors for the report.

The Clean Energy Framework was finalized in May 2021 and adopted by the Forest Preserves’ Board of Commissioners in June 2021. The Framework is available for download at https://fpdcc.com/downloads/plans/FPCC-Clean-Energy-Framework-071221.pdf.

ISTC Technical Assistance Program launches new webpages

TAP homepage

The Illinois Sustainable Technology Center (ISTC) Technical Assistance Program (TAP) has a new web presence. You may now find information on TAP at https://go.illinois.edu/techassist.

TAP makes companies and communities more competitive and resilient with sustainable business practices, technologies, and solutions. TAP works at the intersection of industry, science, and government to help organizations achieve profitable, sustainable results.

The new website makes it easier to find information on TAP programs, services, and projects. Visitors can sign up for free site visits or learn about fee-for-service opportunities to engage our sustainability experts. Any Illinois organization, business, manufacturing facility, institute of higher learning, government entity, public utility, or institution may request one free site visit (per location) at no cost to the facility.

General inquiries may be addressed to istc-info@illinois.edu. You may also reach out to specific TAP team members for assistance in their areas of expertise.

How to safely flush plumbing systems and re-open facilities after shut-down

The domestic plumbing systems in any building or part of a building that has been shut down or has experienced reduced use due to COVID-19 policies are at risk for causing disease and death due to the effects of increased water age, including corrosion and growth of bacteria. Before re-opening any such building, take steps to minimize these risks and include consultation with a licensed plumber.

The Illinois Department of Public Health (IDPH) has a general guidance document for returning these systems to regular use. In Attachment B (Section II, Step 2. b), IDPH recommends setting the water heater to at least 120 degrees F prior to flushing the domestic hot water plumbing.

We recommend a higher temperature of at least 142 degrees F as this will kill Legionella bacteria in the heater within 30 minutes. However, do not use water at this temperature for flushing if the building’s drain waste vent (DWV) materials and/or plumbing system components cannot handle this higher temperature.

WARNING: 142 degree F water can cause third degree burns in seconds. Note that Legionella bacteria can continue to grow at temperatures up to 122 degrees F.

The Environmental Science Policy and Research Institute has written a useful guidance document, Reducing Risk to Staff Flushing Buildings, which offers best practices for flushing building water systems in a way that keeps facility staff safe.

Use the IDPH guidance in conjunction with your facility’s Legionella Water Management Program (WMP). If none exists, we recommend writing a remediation and/or recommissioning plan, then later developing a full WMP. The Centers for Disease Control (CDC) offers a free training program on how to write a WMP and a toolkit to assist in developing a WMP.

Additional recommendations

Drinking Fountains: If these were shut off and/or not used for a period of time, they should be cleaned according to the manufacturer’s instructions before being used again for drinking.

Chlorine levels: The Illinois EPA requires a minimum of 0.5 parts per million Free Chlorine or 1.0 parts per million Total chlorine (also called Combined chlorine) in drinking water, unless a facility has been given an exemption (this is rare, but applies in some cases to facilities supplied with clean well water).

After re-opening, we recommend maintaining 142 degrees F or higher in all domestic water heaters and storage tanks, and 124 degrees F or higher in all recirculating domestic hot water systems for the purpose of reducing the risk of Legionnaire’s Disease. Note that delivered water at fixtures must meet local and state plumbing codes for maximum safe temperature to prevent scalding. The best way to achieve Legionella risk reduction and anti-scalding is to maintain high temperature in tanks and recirculating systems and employ thermostatic mixing valves just prior to point of use fixtures.

Finally, we recommend documenting all actions you take to prepare facilities for re-opening.
