Preface

Climate change is threatening communities across the nation. Millions of Americans feel the
destructive effects of climate change each year when the power goes down, rivers and lakes go dry,
homes are destroyed by wildfires and communities are flooded by hurricanes. Underserved
communities are especially vulnerable to the climate crisis and are more likely to experience the
negative health and environmental effects of extreme weather events.

The Biden-Harris Administration is actively confronting the climate crisis while also advancing
environmental justice. As part of a whole-of-government approach, the U.S. Environmental
Protection Agency is strongly committed to taking the actions necessary to protect human health and
the environment and to increase the resilience of the entire nation, even as the climate changes.

The EPA's commitment to action is reflected in its FY 2022-2024 Strategic Plan and in the 2021
Climate Adaptation Action Plan. Both documents present priority actions the agency will take to
ensure that its programs, policies and operations remain effective under future climate conditions
while we work to support states, territories, tribes and communities in increasing their own adaptive
capacity and resilience to climate change impacts.

From flooding at Superfund sites, to wildfires causing air pollution, to sea-level rise affecting water
quality and infrastructure, the EPA will boldly address climate impacts in both its programs and the
communities it serves. We recognize the importance of tribal, state and local government
partnerships in efficient, effective and equitable implementation of climate change adaptation
strategies. Our plans were informed and improved by input we received in listening sessions we held
to engage these and other partners as we developed these plans.

To ensure we are addressing the climate crisis in a comprehensive way, each of our national program
and regional offices has developed individual Climate Adaptation Implementation Plans that outline
how the EPA will attain the agencywide goals described in the broader Climate Adaptation Action
Plan. These plans describe how programs and regions will integrate climate adaptation into their
programs, partnerships and operations. They also describe how they will help partners build their
resilience and capacity to adapt, while delivering co-benefits, including curbing greenhouse-gas
emissions and other pollution, and promoting public health, economic growth and climate justice. Of
course, the EPA has a major role to play on emissions reductions as well, though that is not the focus

of these plans. Indeed, we must focus on both climate adaptation and mitigation to ensure our nation
and communities thrive in an era of climate change.

As part of this effort, we will empower our staff and partners by increasing awareness of how climate
change may affect our collective ability to implement effective and resilient programs. We will also
provide them with the necessary training, tools, data, information and technical support to make
informed decisions and integrate climate adaptation into our work.

The EPA will work to modernize its financial assistance programs to encourage climate-resilient
investments across the nation. We will also focus on ensuring that investments funded by the
Bipartisan Infrastructure Law, the Inflation Reduction Act and other government programs are
resilient to the impacts of climate change. Finally, as our knowledge advances and as impacts
continue to develop, our response will likewise evolve. We will work to share these developments to
enhance the collective resilience of our nation.

The actions outlined in these implementation plans reflect the EPA's commitment to build every
community's capacity to anticipate, prepare for, adapt to and recover from the increasingly
destructive impacts of climate change. Together with our partners, we will work to create a healthy
and prosperous nation that is resilient to the ever-increasing impacts of climate change — which is
vital to the EPA's goal of protecting human health and the environment and to ensuring the long-term
success of our nation.

Climate Adaptation Implementation Plan

The U.S. Environmental Protection Agency (EPA) is committed to identifying and responding to the
challenges that a changing climate poses to human health and the environment. In 2014, EPA released
an Agency-wide Climate Change Adaptation Plan. In turn, EPA National Program Offices, all 10 EPA
Regional Offices, and several EPA National Support Offices released Climate Adaptation
Implementation Plans in 2014. These documents contained "vulnerability assessments" that analyzed
how climate change might affect the work of the Agency, as well as priority activities to address these
vulnerabilities.

The January 27, 2021, Executive Order (E.O.) 14008 entitled Tackling the Climate Crisis at Home and
Abroad' directs all federal agencies to prepare Climate Adaptation Action Plans. To begin this process,
on May 26, 2021, EPA Administrator Michael Regan issued an updated Policy Statement on Climate
Adaptation. In the Policy Statement, the Administrator directed all EPA National Program and Regional
Offices to update their 2014 Climate Adaptation Implementation Plans. In October 2021, EPA, along
with over 20 other federal agencies, released an Agency-wide 2021 Climate Adaptation Action Plan11 in
response toE.O. 14008.

EPA's Climate Adaptation Action Plan reinforces that the impacts of climate change within and across
U.S. regions will not be distributed equally and recognizes that certain communities and individuals are
particularly vulnerable to the impacts of climate change. EPA commits to prioritizing the most
vulnerable populations with the goal of attaining a more equitable, just, and resilient future within and
across communities.111

EPA Region 8, through its updated Climate Adaptation Implementation Plan, commits to:

•	Leverage Region 8 programs and resources to promote state, tribal, and community adaptation to
climate change, with a particular focus on advancing environmental justice.

•	Place a priority on building climate resiliency in populations that are particularly vulnerable to
the impacts of climate change, such as low-income communities, communities of color, children,
the elderly, communities situated in air quality non-attainment areas, persons with asthma and
other chronic respiratory issues, the homeless, outdoor workers, and Indigenous Peoples.

•	Work with our external partners to leverage expertise and resources, with a particular emphasis
on overburdened and vulnerable populations.

•	Recognize that different parts of Region 8 are experiencing different climate change impacts and
to differing degrees, thus have diverse climate adaptation needs.

•	Maintain an internal climate change workgroup to facilitate cross-division communication and
coordination.

The updated Region 8 Climate Adaptation Implementation Plan, along with all updated EPA National
Program Office, National Support Office, and Regional Office plans, includes the following five
elements:

•	Designation of a Senior Career Leader responsible for overseeing climate adaptation activities in
EPA Region 8.

•	Updated Climate Vulnerability Assessment specific to EPA Region 8.

•	Priority Actions that will be taken by EPA Region 8 to address the Agency-wide priorities
identified by EPA's Agency-wide 2021 Climate Adaptation Action Plan.

•	A training plan for enhancing staff knowledge about climate adaptation.

•	Identification of science needs.

EPA Region 8 has designated Daniel Heffernan, Associate Deputy Regional Administrator, as its Senior
Career Leader responsible for overseeing climate adaptation activities in Region 8.

Region 8 formed a Climate Adaptation Team (Table 1) in late 2021 comprised of representatives
appointed from each division and office. The Climate Adaptation Team led the development of this
updated Region 8 Climate Adaptation Implementation Plan and will guide implementation of the Plan
and associated priority actions in the coming years.

Throughout Region 8's Climate Adaptation Implementation Plan, the terms climate change adaptation,
adaptive capacity, climate resilience, and climate change mitigation are used. Table 2 provides these key
definitions.

Table 2. Key Definitions"

Climate change
adaptation

or climate adaptation means taking action to prepare for and adjust to
both the current and projected impacts of climate change.

Adaptive capacity

is the ability of a human or natural system to adjust to climate change
(including climate variability and extremes) by moderating potential
damages, taking advantage of opportunities, or coping with the
consequences.

Climate resilience

can be generally defined as the capacity of a system to maintain function
in the face of stresses imposed by climate change and to adapt the system
to be better prepared for future climate impacts.

Climate change mitigation

refers to actions limiting the magnitude and rate of future climate change
by reducing greenhouse gas emissions.

Climate Adaptation Implementation Plan

2.1 Background

EPA Region 8's climate vulnerability assessment builds upon the assessment developed for the 2014
Region 8 Climate Adaptation Implementation Plan and reflects the latest scientific information
contained in the Fourth U.S. National Climate Assessment (NCA4),V and EPA's Climate Change
Indicators in the United States." The climate vulnerability assessment contains an updated list of climate
change impacts in Region 8, and considers:

•	How EPA Region 8 programs are vulnerable to the impacts.

•	How the impacts may affect vulnerable populations.

•	Actions taken to address the risks, remaining vulnerabilities, and barriers to further actions.

•	Resource and budget issues.

Vulnerabilities were considered for the following Region 8 program areas:

•	Facilities, Operations, and Workforce

•	Air Programs

•	Water Programs

•	Chemical Safety and Pollution Prevention Programs

•	Emergency Response and Waste Management Programs

•	Enforcing Environmental Laws and Ensuring Compliance

Vulnerable Populations. Vulnerable populations are mentioned throughout Region 8's climate
vulnerability assessment. Populations vulnerable to climate change impacts may include children, the
elderly, people of color, low-income communities, persons with underlying medical conditions and
disabilities, those with limited access to information, Indigenous populations, communities
overburdened by pollution, and the homeless and outdoor workers who may have more exposure to heat
and air pollution. Certain geographic locations may also contribute to vulnerability, such as areas of air
quality non-attainment.

In September 2021, EPA released a report entitled Climate Change and Social Vulnerability in the
United States: A Focus on Six Impact Sectors,™ an environmental justice study that looks at how
projected climate change impacts may be distributed across the American public. The analysis shows
that the most severe harms from climate change fall disproportionately upon underserved
communities who are least able to prepare for, and recover from, heat waves, poor air quality,
flooding, and other impacts. EPA's analysis indicates that racial and ethnic minority communities are
particularly vulnerable to the greatest impacts of climate change.

Advancing Environmental Justice. EPA's climate adaptation planning supports the Agency's and
government-wide efforts to advance environmental justice. EPA Region 8's Climate Adaptation
Implementation Plan, and the priority actions found within, support the Agency's efforts to strengthen
the adaptive capacities and increase the resilience of the nation by consulting and partnering with states,
tribes, territories, local governments, environmental justice organizations, community groups,
businesses, and other federal agencies, with a particular focus on environmental justice. When

integrating climate adaptation into the Agency's programs, policies, and processes, EPA will account for
the impacts of climate change and related environmental justice concerns. EPA places a special
emphasis on working with overburdened and vulnerable populations to increase their resilience to
climate change. Such populations include communities of color, low-income communities, children,
persons with disabilities, the elderly, tribes, and Indigenous Peoples. These groups and individuals may
be especially vulnerable to climate change impacts due to a variety of factors including higher pollution
burdens, disproportionate exposure to environmental contaminants, lack of financial resources, limited
access to quality health care, and other barriers/111

Rural Communities. Region 8 is home to some of the most rural counties in the nation. Region 8 lacks
the urban areas that other parts of the country have, relatively speaking, as almost 50% of the area (145
out of the 291 counties) is classified as "100% or completely rural," according to the U.S. Census
counties. Out of the 10 EPA regions, Region 8 is ranked 2nd in terms of having the highest number of
"100%> rural" counties. Throughout its climate adaptation planning, Region 8 will consider the unique
needs of our rural communities. EPA Region 8 understands that the challenges posed by climate change
and the obstacles to adapting to a changing climate in these communities are often different than those in
urban and suburban areas and may require unique solutions and targeted assistance.

Tribes and Indigenous Peoples. Indigenous Peoples may also be particularly vulnerable to the impacts
of climate change due to the integral nature of the environment within their traditional lifeways and
cultures. Region 8 places a priority on the development of adaptation strategies that promote
sustainability and reduce the impact of climate change on Indigenous Peoples, with a focus on
Indigenous Traditional Ecological Knowledge (ITEK). ITEK refers to knowledge, which have
accumulated over generations through direct contact with the environment, that focus on the
relationships between humans, plants, animals, natural phenomena, and the landscape. Indigenous
knowledge broadly includes systems of observing, monitoring, researching, recording, communicating,
and learning, and their social adaptive capacity to adjust to or prepare for changes.1X

EPA values its unique relationship with Indian tribes and recognizes and supports the sovereign
decision-making authority of tribal governments. Under the Constitution, treaties with tribal nations are
part of the supreme law of the land, establishing unique sets of rights, benefits and conditions for the
treaty-making tribes who were forced to cede millions of acres of their homelands to the United States,
in return for recognition of property rights in land and resources as well as federal protections. Tribal
treaty rights have the same legal force and effect as federal statutes and they should be integrated into
and given the fullest consideration throughout EPA's collective work. Reserved rights are the rights
tribes retain that were not expressly granted to the United States by tribes in treaties. Treaty and reserved
rights, including but not limited to the rights to hunt, fish and gather, may be found both on and off-
reservation lands. Agencies should consider treaty and reserved rights in developing and implementing
climate adaption plans in order to protect these rights and ensure the Agencies meet their legal and
statutory obligations and other mission priorities as we work to combat the climate crisis.

In September 2021, EPA joined 16 other federal agencies in signing a Memorandum of
Understanding (MOU)x that committed those parties to identifying and protecting tribal treaty rights
early in the decision-making and regulatory processes. Accordingly, EPA will consider and protect

treaty and reserved rights in developing and implementing climate adaptation plans through
strengthened consultation, additional staff training and annual reporting requirements.

2.2 Regional Description

EPA Region 8's "Mountains and Plains" office serves Colorado (CO), Montana (MT), North Dakota
(ND), South Dakota (SD), Utah (UT), Wyoming (WY), and 28 Tribal Nations. Region 8 encompasses
two different climate regions, as defined by the U.S. Global Change Research Program (USGCRP)X1- the
Southwest (CO and UT) and the Northern Great Plains (MT, ND, SD, and WY).

Region 8 states and sovereign tribal nations encompass the heart of the American West, including much
of the Rocky Mountains, Great Plains, and Colorado Plateau. Over two-thirds of the Region's roughly
10 million people live in two distinct bands of urban development- Colorado's Front Range and Utah's
Wasatch Front.™ Region 8 is characterized by vast open spaces, including mountains, plains, canyons,
and deserts, as well as small population centers. Region 8 is home to some of the most iconic
landscapes, including Yellowstone, Glacier, Rocky Mountain, Badlands, and Zion National Parks, as
well as dozens more national parks, national monuments, and forests. Region 8 encompasses range,
farm, and grass lands.

Region 8 is arid, stressing the availability and quality of water resources, particularly to meet competing
demands from industry and human consumption. Many water resources originate in Region 8, such as
the Missouri, Rio Grande, Colorado, Arkansas, and Platte rivers. Due to the significant amount of
publicly owned lands, partnership with other federal agencies such as the U.S. Forest Service (USFS),
the Bureau of Land Management (BLM), the National Park Service (NPS), and the Federal Emergency
Management Agency (FEMA), is critical. The 28 sovereign tribal nations collectively make up an area
in Region 8 the size of Tennessee. Region 8 works closely with other federal agencies, these 28 tribal
nations, as well as state and local governments to protect human health and safeguard the natural
environment.

2.3 Climate Change Impacts in EPA Region 8

EPA Region 8 has identified climate change impacts that may affect the Region and our programmatic
work (Table 3). The impacts are premised on the measurable increase of greenhouse gases in the
atmosphere™1 and may be considered individually or in combination. Impacts are referenced to the U.S.
Global Change Research Program (USGCRP)'s Fourth National Climate Assessment and/or the U.S.
EPA's Climate Change Indicators in the United States (see references for more detail).

2.4 EPA Region 8 Program Vulnerabilities
Facilities, Operations, and Workforce

Region 8's headquarters building is located at 1595 Wynkoop Street in downtown Denver, Colorado.
Region 8 also operates an office in the Baucus Federal Building in Helena, Montana and a laboratory in
the Denver Federal Center in Lakewood, Colorado.

The operation of EPA Region 8 facilities may be affected. Increasing air temperatures and climate
extremes may affect cooling and heating requirements in Region 8 facilities. The operation of Region 8
facilities could also be affected by water shortages due to drought, and electric power interruptions due
to extreme weather events and wildfires. Drought, extreme temperatures, and extreme precipitation
events may also make it more difficult to maintain the viability of green roofs upon which Region 8
relies for stormwater retention services at its headquarters building in Denver, Colorado. Region 8 has
been adapting to these impacts by reducing its energy and water use and by maximizing the ability of
personnel to work remotely for an extended period of time. Building air filtration has also been
upgraded in many locations, and the Region is exploring the availability of heat pumps and micro grids
to provide localized cooling, heating, and electric power to build long-term resiliency and reduce its
environmental footprint. Resource and budget issues may delay or prevent the implementation of many
desired actions and the tracking of performance over time.

Air Programs

Tropospheric ozone pollution is likely to increase in certain areas due to the effects of climate
change. Higher temperatures and regional air stagnation associated with climate change may lead to the
formation of more tropospheric or ground-level ozone even with the same level of emissions. While
tropospheric ozone is higher in urban areas, some rural and tribal areas may also be affected due to
widespread oil and gas development. Additionally, background levels of tropospheric ozone are
increasingly becoming more elevated due to atmospheric transport and increasing contributions from
wildfire smoke. Climate change also has the potential to lengthen the ozone season by increasing time
throughout the year conducive to the formation of tropospheric (ground level) ozone. Vulnerable
populations and active individuals are at a higher risk for health effects from exposure to increased
ozone concentrations.

Particulate matter (PM) levels are likely to be affected by increased frequency and intensity of
wildfires. There is evidence indicating that climate change will elevate PM levels through increases in
the frequency and intensity of wildfires. Impacts from large scale wildfires affect regional air quality on
scales so vast that populations impacted by the smoke may not be able to escape areas with very poor air
quality. The Intergovernmental Panel on Climate Change (IPCC) has reported with very high confidence
that in North America, disturbances such as wildfires are increasing and are likely to intensify in a
warmer future with drier soils and longer growing seasons. Forest fires are likely to increase in
frequency, severity, distribution, and duration in the Intermountain West and the West due to climate
change. This regional area is also downwind from smoke and pollutant transport emanating from the

Page 13 | 53

Climate Adaptation Implementation Plan

Pacific Northwest and Canada. This, in addition to the recent pine beetle outbreak in the Rocky
Mountains, is changing the fire regime in the area and complicating Region 8's efforts to protect public
health and the environment from PM pollution. Additionally, drought conditions may increase dust
storms and contribute to degraded air quality due to PM. Vulnerable populations may be especially at
risk from increased exposure to PM.

Climate change may impact air quality monitoring, standards, planning and permitting
programs. Region 8 can adapt to climate driven changes in air quality trends using existing regulatory
processes. However, it may be necessary to develop new regulatory and policy tools to address
persistent large scale air quality issues. EPA uses monitoring data to inform decisions and apply the
appropriate regulatory framework. Monitoring of some pollutants and some areas has decreased as urban
air quality trends drastically improved since the 1970s, 80s, and 90s. However, with increasing
population and energy development, fuel consumption, and the potential for climate-driven extreme
events such as severe wildfires, there may be value and need to expand monitoring networks in areas
heretofore unmonitored. Monitoring information is important to protect populations from extremely
poor air quality as well as to verify air modeling. High quality air quality modeling is important to
project the effects that EPA and state decisions may have on air quality.

National Ambient Air Quality Standards (NAAQS) are set to protect public health and the environment.
If an area does not meet the NAAQS for any of the six criteria pollutants, the area must be designated as
nonattainment for the NAAQS for that pollutant and the state must develop a plan for how the state will
attain and maintain the NAAQS in that area. The state's plan is submitted to EPA for approval. If air
quality is greatly affected by climate-driven events, it may be necessary to reevaluate existing regulation
and policy, which currently allows for the exclusion of exceptional events such as wildfires or high
winds from some regulatory determinations, including decisions as to whether an area has attained the
NAAQS. While these events may not be in the control of regulators, or any person in some cases, they
nevertheless affect human health and the environment.

Permitting programs for stationary sources are another mechanism that EPA and the states use to protect
air quality. EPA and the states can use these programs to adapt to changing trends in air quality that have
already started to occur, but we may be limited in how we can use permitting programs to deal with
changes that have not yet been experienced.

In addition, Region 8's Air and Radiation Division assists the Region's National Environmental Policy
Act (NEPA) program in developing and providing comments pursuant to Clean Air Act Section 309 and
NEPA, to other federal agencies regarding potential air quality impacts of proposed federal actions that
may significantly affect the quality of the human environment. EPA provides recommendations to lead
federal agencies for analyzing and mitigating greenhouse gas emissions and for adaptation to
environmental impacts that may be exacerbated by climate change.

Climate change may worsen indoor air quality (IAQ) and increase exposures. Changes in the
climate can affect the air we breathe indoors in many ways. The worsening quality of outdoor air can
infiltrate indoors. Rising carbon dioxide (CO2) levels and warmer temperatures can increase outdoor
airborne allergens, which can also contaminate indoor spaces. Warmer temperatures and shifting
weather patterns can lead to more frequent and severe wildfires. In turn, wildfire smoke can infiltrate
and contribute to levels of indoor particulate matter.


-------
U.S. Environmental Protection Agency Region 8

Climate Adaptation Implementation Plan

Climate change is also increasing the risk of extreme weather events such as extreme precipitation that
can lead to flooding, which can result in damage to buildings and allow water or moisture to enter
indoors. Increased indoor dampness and humidity can lead to more mold, dust mites, bacteria, and other
biological contaminants indoors. Extreme weather events can also create conditions that support
increases in pests and infectious agents that can make their way indoors. As more frequent and more
intense weather events occur, power outages are more likely. These outages make it more difficult to
maintain comfortable indoor temperatures and healthy indoor air quality, and subsequently lead to more
frequent use of portable generators. Carbon monoxide poisoning from improper use of portable
generators results in hundreds of deaths and thousands of illnesses each year.

As climate change exacerbates these and more IAQ issues, vulnerable populations may be
disproportionately impacted. For example, people in low-income areas may be more likely to be
exposed to indoor air contaminants because they have fewer resources to mitigate the impacts of these
contaminants. Similarly, landlords often lack incentive to provide healthy indoor environments for their
tenants, causing rental properties to be notorious for IAQ issues such as mold infestations and high
radon levels.

Region 8 can utilize various EPA programs, tools, resources, and partnerships to adapt to this impact.
Region 8's IAQ, Safer Choice, Pollution Prevention, ENERGY STAR® and the Clean, Green and
Healthy Schools programs are avenues through which public education and preparedness measures
could occur. EPA's Indoor airPLUS program helps builders to construct new homes to specifications
that minimize exposure to indoor airborne pollutants and contaminants. Similarly, by incorporating IAQ
considerations into building renovations alongside energy efficiency upgrades, existing Region 8
buildings can be made more resilient to climate change and its IAQ impacts.

Water Programs

Climate change impacts, such as warmer temperatures, heavier precipitation, and drought, may
affect EPA Region 8's ability to protect and restore watersheds, aquatic ecosystems, and wetlands.

Warmer air temperatures will result in warmer water, potentially leading to low oxygen levels and
hypoxia, harmful algal blooms (HABs), and changes in the toxicity of some pollutants. Colder water
aquatic organisms may be replaced by species better adapted to warmer waters, and this process may
occur at an uneven pace disrupting aquatic system health and allowing non-indigenous and/or invasive
species to become established. Additionally, temperature increases may lead to water losses from
increased evapotranspiration rates. Surface water quality can decline as water temperatures increase and
more frequent high-intensity rainfall events mobilize pollutants. Indirect impacts on water quality are
also possible in response to an increased frequency of forest pest/disease outbreaks, wildfires and
resultant debris flows, and other terrestrial ecosystem changes. Wildfires create ash and debris that can
end up in reservoirs, rivers, canals, and pipelines, and ultimately into municipal water-treatment
facilities. Fires also scorch soils, leading to more runoff and erosion.

Heavier precipitation may increase flood risk, expand floodplain area inundated, increase the variability
of and magnitude of streamflow, and increase streambank and bed erosion from high water velocities.
Increases in storm event frequency and intensity can also result in more nutrients, pathogens, and toxins

being washed into water bodies, especially if they force an increase in sewer overflows and wastewater
bypasses. Extreme precipitation events are projected to increase and may lead to more severe floods and
greater risk of water and wastewater infrastructure failure in some regions. Drought, changing patterns
of precipitation, reduced snowpack, earlier spring runoff, and increased evapotranspiration may lead to
reduced streamflow later in the summer, potentially altering stream and lake permanence, impacting
resident aquatic communities, and increasing water quality impairments. Certain aquatic ecosystems that
are unique to the region may also be threatened, such as the prairie potholes of North and South Dakota,
reducing their water recharge function and the habitat they provide for plants and animals.

Additionally, in several ways, climate change is altering the timing and length of the snowpack within
Region 8. For example, the ongoing pine beetle outbreak in the Rocky Mountains has altered the
hydrological functioning of these mountain ecosystems by influencing snow distribution and snowmelt
in complex ways. Studies suggest that warming temperatures are allowing pine beetles, which normally
reproduce just once a year, to reproduce twice annually. Pine beetle outbreaks, in addition to quickly
leading to death of pines, can potentially cause a forest which is typically considered a "carbon sink"
become a "carbon source." Studies indicate that increased pine beetle activity may impact snow
accumulation and melt, triggering earlier snowmelt and increased water yields from snowpack that
accumulates beneath affected pine trees.xxxvm

Other considerations that affect the timing of snowmelt include increased dust deposition and rain on
snow events. Specifically, increased air temperatures have reduced the fraction of winter precipitation
occurring as snow in the western United States and warming has resulted in a shift in the timing of
snowmelt runoff to earlier in the year. Long-term datasets and future climate projections both indicate
large declines in snowpack in the West. Glaciers continue to melt in the western United States and
resultant shifts in the hydrological regime due to glacial melting will alter stream water volume, water
temperature, runoff timing and aquatic ecosystems in this region.

Significant changes in both water quantity and quality are already being observed in the southwest, and
continued drought conditions exacerbate pressures on already stressed aquatic ecosystems. Annual
precipitation has decreased in the west and southwest and current projections indicate that parts of the
southwest will receive less precipitation in winter and spring moving forward. Intensifying droughts,
increasing heavy downpours and reduced snowpack are combining with increased water demand to our
impact water supply within the Region.

Warmer temperatures and heavy precipitation associated with climate change contribute to the
development of HABs. HABs can introduce toxin-producing cyanobacteria into recreational and
drinking water sources, resulting in necessary restrictions on access and use. Conditions that encourage
cyanobacteria growth such as higher water temperatures, increased runoff, and episodic increases in
nutrient loading, are all projected to occur more frequently in Region 8 with climate change, thereby
increasing the frequency, magnitude, and risk of HABs.

The impacts discussed above may have adverse effects on Region 8's work to protect water quality, the
health of watersheds, aquatic ecosystems and wetlands, and the recovery of threatened fish species (e.g.,
the cold water-dependent bull trout in western Montana). Additionally, more waterbodies may have
trouble meeting a variety of climate-sensitive water quality standards and may need to be listed as
impaired, thus requiring the development of a total maximum daily load (TMDL). Nonpoint source

pollution control programs may need to be adjusted to reflect changing conditions, source water
protection practices may need to be updated and/or enhanced, and baselines used in water quality
standard development and implementation could shift, requiring new scientific analyses to be valid.
Finally, certain economic and cultural practices of tribal communities related to water may be impacted.
These program vulnerabilities may require greater use of biological monitoring and assessment
techniques to understand trends, management techniques that build resilience into aquatic environments,
and the increased management of wetlands for stormwater control purposes and to buffer the impacts of
drought.

The current trend of research may need to be refocused to address shifts in water quality. Region 8's
capacity to adapt to this impact is varied, and there may be numerous opportunities that can be explored.
For example, Region 8 provides ongoing support to its states and tribes to monitor and analyze samples
from suspected HABs, as well as regular information sharing opportunities throughout the year. EPA
has partnered with the National Aeronautics and Space Administration (NASA) and the National
Oceanic and Atmospheric Administration (NOAA) to create the Cyanobacteria Assessment Network
(CyAN) utilizing daily satellite data to serve as an early warning system for HABs to states, tribes, and
other federal partners (covering over 2,000 lakes and reservoirs in the United States).

Climate change impacts, such as heavier precipitation and drought, may affect drinking water,
wastewater, and stormwater infrastructure. Heavier precipitation may increase the risk of floods,
expand floodplains, and cause more nutrients, pathogens, and toxins to be washed into waterbodies. This
could damage or overwhelm water infrastructure, leading to releases of waterborne diseases and
pathogens in the environment. In urban areas, stormwater collection and management systems may need
to be redesigned to provide increased capacity. Low stream flows resulting from drought, earlier spring
runoffs, reduction in snowpack, and increased evapotranspiration may affect drinking water storage and
distribution systems, drinking water intakes, and dilution flows available at wastewater outfalls. To date,
no comprehensive assessment has been conducted to robustly evaluate climate-related vulnerabilities of
Unites States water infrastructure, to evaluate the potential resulting damages, or to estimate the costs of
reconstruction and recovery. There is a need to better understand the condition of water infrastructure
nationally in order to identify areas of greatest risk. Infrastructure design, operation, financing, and
regulatory standards typically do not account for a changing climate and are not optimized to address
changing conditions. Changes in frequency and intensity of climate extremes relative to the 20th century
and deteriorating water infrastructure are contributing to declining community and ecosystem resilience.
Moving forward, drinking water and wastewater utilities will need to consider these impacts and the
concept of non-stationarity in their planning activities. Non-stationarity refers to the concept that, as the
climate changes, the magnitude, duration, and frequency of impacts such as drought and flooding may
occur outside the historical observation range, thus making it more challenging to predict or plan for the
future water conditions. Additionally, vulnerable populations may have problems accessing safe
drinking water due to these infrastructure challenges.

Clean Water and Drinking Water State Revolving Funds (SRF) may need to be increased as the need for
additional investments in water infrastructure increases. Region 8 and its state and tribal partners may
need to re-prioritize project requests due to increasing and changing needs at the local level. Tribes and
other vulnerable populations, including small and rural communities, may require special considerations
with respect to climate change and water infrastructure challenges. Region 8's work to promote green

Climate Adaptation Implementation Plan

infrastructure in urban areas may be more in demand to serve multiple purposes: to manage storm water
runoff, to provide flood mitigation, to manage air quality, and to reduce the urban heat island effect.

The quality and availability of safe drinking water may be affected. Drought, changing patterns of
precipitation and snowmelt, increased evapotranspiration, and reduced snowpack may result in changes
to the availability and demand for drinking water. Competition for water for agriculture, industry, fire
protection, and energy production purposes may also increase, especially in areas experiencing
population growth. These factors may shift demand to underground aquifers, or prompt development of
reservoirs or other water retention strategies.

Under drought conditions, a decrease in surface water resources can lead to increased reliance on
groundwater aquifers. This is already happening in many western U.S. areas. When long-term pumping
exceeds the recharge rate, pore space collapse can occur and lead to compaction of the aquifer. When
this occurs, that portion of the aquifer loses the ability to be recharged and thus the aquifer's storage
capacity is decreased. This type of system compression is referred to as aquifer compaction and is
responsible for permanent land subsidence.

Soil erosion and increased runoff following wildfires can foul water and challenge water-treatment
facilities. Heavy precipitation events may exacerbate this problem, leading to more runoff of sediment
and other contaminants into drinking water sources, requiring additional treatment. Drinking water
intakes and wastewater outfalls could also become overwhelmed or damaged, causing an increased
incidence of waterborne diseases and pathogens. Increased water temperatures may also lead to an
increased growth of algae and microbes that may affect drinking water quality. These impacts may have
adverse effects on the ability of public water supplies to cost-effectively meet drinking water standards.
Smaller and rural communities could face additional resource challenges if faced with the need to
rapidly adapt to changing quality and availability of water.

Various Region 8 programs protect drinking water quality and are concerned with the availability of safe
water supplies. National Pollutant Discharge Elimination System (NPDES) discharge permits for
wastewater and stormwater from municipal and other facilities may need to be adjusted to maintain
water quality under future climate regimes. As the need for water retention grows, an increase in Clean
Water Act (CWA) Section 404 permits may be necessary and NEPA reviews of water supply and
storage projects may increase. There may also be a need to enhance or construct wetlands, that could
require CWA Section 404 permits.

Limited water availability and drought in some regions may require drinking water providers to reassess
the security and stability of their water supplies, and consider alternative pricing, allocation, and water
conservation options. Region 8's work to promote voluntary actions through its various initiatives may
be more in demand.

Chemical Safety and Pollution Prevention Programs

Heavy precipitation events, floods, extreme temperatures, and wildfires may threaten the
structural integrity and safe operation of underground storage tanks (USTs). Throughout urban and
rural areas, USTs are used to store petroleum and other materials that can be hazardous when released

Page 18 | 53


-------
U.S. Environmental Protection Agency Region 8

Climate Adaptation Implementation Plan

into the environment. Extreme events may cause an increase in leaking USTs (LUSTs) and subsequently
an increased need for cleanup and response. The Region 8 Resource Conservation and Recovery Act
(RCRA) Branch would help the state UST and LUST programs prepare for and respond to impacts to
USTs. The RCRA Branch would also need to respond to a potential increased LUSTs in Region 8's
Indian country.

Sites at which polychlorinated biphenyls (PCBs) are disposed in-place located in zones at risk for
heavy precipitation events, floods, extreme temperatures, and wildfires have increased potential
for PCBs to be mobilized. Toxic Substances Control Act (TSCA) submittals to EPA for such sites
typically do not consider increased risk from natural events caused by climate change. However, TSCA
disposal-in-place remedies are intended to remain effective in perpetuity (or until the contamination is
removed with EPA approval, as needed). Remedial decisions for PCB and RCRA sites or facilities often
rely upon engineering controls, including pumps and electrical equipment, and physical barriers (e.g.,
hard caps, liners) to ensure protectiveness over time. Region 8 needs to ensure that both its RCRA and
PCB cleanup site remedies and permit decisions are sufficiently resilient to withstand the effects of
severe weather events, as well as increased risk of fire danger for select sites/conditions.

Climate change may result in an increased role for pollution prevention. Pollution prevention (P2)
approaches can be applied to all potential and actual pollution-generating activities, including those
found in the energy, agriculture, federal, consumer and industrial sectors. Prevention practices are
essential for preserving wetlands, groundwater sources and other critical ecosystems; areas in which it is
important to stop pollution before it begins.

EPA Region 8's programs may see an increase in and need for additional promotion, education, and
adoption of P2 awareness and best practices. This work is mostly implemented through the P2 and
Source Reduction Assistance Grant programs where grantees work with individual businesses to
implement P2 measures. These P2 solutions are then transferred to other businesses and the larger
industry. The Region 8 P2 program, in conjunction with grantees, may need to increase awareness with
consumers, manufactures, small businesses, and the general public and assist with identifying ways they
can implement water and energy conservation practices, adopt less environmentally harmful pesticides,
modify production processes to produce less waste, substitution of non-toxic or less toxic chemicals as
cleaners, degreasers and other maintenance chemicals, reusing materials such as drums and pallets rather
than disposing of them as waste.

Region 8 can utilize various EPA programs, tools, resources, and partnerships, such as WaterSense,

Safer Choice, Sustainable Materials Management (SMM), and ENERGY STAR® to assist with
adapting to this growing need. However, it will depend on all available resources.

Climate change may affect exposures to a wide range of chemicals because of changing
environmental conditions or use patterns. For example, it may lead to increased pest pressure and a
changing mix of pests, affecting how, when, where, and what pesticides are used. The earlier timing of
spring events, like the emergence of leaves, flowers, and pollinators, may lead to a longer growing
season and an increase in the quantity of pesticides used. Other climate impacts like extreme
temperatures and heavy precipitation may lead to reduced crop yields, fields taken out of production,
changes in crop mixes and farming methods, and increased runoff into streams and rivers, increasing
exposures. There may also be an increase in the use of insecticides and rodenticides to control

age 19 | 53

U.S. Environmental Protection Agency Region 8

Climate Adaptation Implementation Plan

mosquitoes and rodents in response to certain health threats. Vulnerable populations may be at a higher
risk for health effects from exposure to pesticides. Generally speaking, changes in climate may impact
where a wider variety of species, in addition to "pests," migrate. This may impact which chemistry can
be used and/or how it can be used.

Region 8's programs may see an increase in requests for emergency exemptions for unregistered
pesticides, state/local special need registrations, as well as requests to approve additional or new end
uses of registered products. These requests are mostly handled by EPA Headquarters, but Region 8
monitors and supports them as appropriate to ensure a timely response. Additionally, Region 8's
work to promote Integrated Pest Management and other sustainable agriculture practices may be in
greater demand. Region 8's adaptive capacity to this growing need is largely dependent on available
funding and resources.

Climate change may affect brownfield revitalization. Brownfield revitalization—the sustainable
redevelopment of contaminated and abandoned properties—can support community efforts to
become more resilient to climate change impacts by incorporating adaptation strategies throughout
the assessment, cleanup, and redevelopment process. When planning for assessment and cleanup, it
is important to identify community priorities related to assessment, cleanup, and long-term
revitalization of brownfields. Planning should also include an evaluation of existing environmental
conditions, zoning and building codes, local market potential, and needed infrastructure
improvements. The redevelopment phase of a brownfield project provides the visible end product of
community planning and commitment to climate change resiliency and mitigation. Each brownfield
redevelopment also provides the opportunity to improve the connectivity of various elements of the
built environment to meet the economic, environmental, and local health and welfare needs of
revitalizing communities. Throughout the brownfield revitalization process, particular attention
should be paid to equitable development to prevent displacement and ensure the improvements meet
the needs of longtime residents.

Emergency Response and Waste Management Programs

EPA Region 8's emergency response and disaster mitigation and recovery efforts may increase
due to an increasing risk of heavy precipitation events, floods, drought, and wildfires, as well as
other extreme weather events like severe winds and tornados. EPA has authority under the
Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), Clean Water
Act (CWA), and other statutes to respond to various releases/discharges that present a threat to public
health or the environment. Such releases/discharges may increase if extreme weather events damage
industrial facilities or otherwise lead to damage. EPA also has a role in responding to national disasters
under the National Response Framework (NRF). Under the NRF, EPA is the lead for Emergency
Support Function (ESF) 10 Oil & Hazardous Materials and supports numerous other ESFs. Increased
extreme weather events could lead to greater disasters which could then lead to more requests for EPA
assistance. If EPA assistance during disaster response is required, this work is tasked by the Federal
Emergency Management Agency (FEMA) via a mission assignment. Mission assignments are typically
issued to EPA under ESF10 or ESF3, but EPA could be tasked under any of the ESFs depending on the

Page 20 | 53


-------
U.S. Environmental Protection Agency Region 8

Climate Adaptation Implementation Plan

assistance requested. Work conducted under mission assignment is funded by the Stafford Act Disaster
Relieve Fund (managed by FEMA) and a cost share paid by the affected state.

In addition to federally coordinated disaster response activities, FEMA also coordinates federal recovery
and mitigation activities. The National Disaster Recovery Framework (NDRF) gives structure to, and
expands, the nation's commitment to these activities. EPA is listed as a possible resource agency in five
of the six NDRF Resource Support Function (RSF) areas. Following a Presidential Disaster Declaration,
FEMA may activate the NDRF to provide federal support to state and local recovery efforts by
activating one or more RSFs. EPA is a primary agency for Health and Social Services and Natural and
Cultural Resources RSFs. Federal support is coordinated by the corresponding FEMA region with the
impacted state(s), territory(ies), tribe(s), and/or communities. EPA recovery support may be requested
by FEMA and/or the state. For example, FEMA may request EPA to provide a Sustainability Advisor to
advise the Federal Coordinating Officer (FCO), RSF teams, state partners, and local officials on
sustainable communities, climate adaptation, resiliency, green and energy efficient growth, and
materials and products for recovery planning and construction. The Sustainability Advisor is one of
many recovery roles or resources that may be requested of EPA. The impacted EPA region is
responsible for deciding how this type of staffing would happen, in consultation with and support from
OHS and other headquarters programs. FEMA would provide funding under a mission assignment or
individual assistance for EPA activities under NDRF.

While most mitigation activities occur at the local and regional levels, federal agencies, including EPA,
play a critical role in supporting and incentivizing these actions using federal resources. Coordination
among EPA programs and other federal agencies is necessary to successfully support communities, to
effectively leverage federal funds to further EPA's mission, and to track how funds are used. Close
coordination with state, tribal, territorial, and local agencies is also critical to ensure that communities
are well served before and after disasters.

As defined in the NMF, mitigation supports protection and prevention activities, eases response, and
speeds recovery to create better prepared and more resilient communities. Mitigation efforts can come
well before a disaster occurs, but they may also be used as part of recovery to break the cycle of disaster
damage, reconstruction, and repeated damage.

One of EPA's Mitigation and Recovery Principles is to promote sustainable and resilient rebuilding;
meaning to use EPA's expertise to inform federal, state, tribal, territorial, and local partners about
rebuilding for the long-term viability of the affected area's people, economies, and natural ecosystems,
including:

•	Helping communities adapt to climate change, anticipate disaster impacts to infrastructure,
and incorporate green infrastructure, sustainable materials management, and other adaptation
strategies for mitigation and recovery planning;

•	Helping communities define a shared vision for mitigation and rebuilding;

•	Collaborating with other federal agencies to leverage all federal resources in support of
sustainable and resilient recovery; and

•	Partnering with non-federal agencies and organizations to leverage non-federal funds for
resilient rebuilding, where appropriate.


-------
U.S. Environmental Protection Agency Region 8

Climate Adaptation Implementation Plan

As the frequency and intensity of climate-related natural disasters increase, it is likely response,
recovery and mitigation needs will also increase. This may create a high demand on EPA staff and
resources, especially if disasters are simultaneous and/or overlapping.

The most common program areas involved in response and recovery efforts include disposal of
household hazardous waste, contaminated debris management, project permitting (for drinking water,
wastewater, and storm water management), site assessments, sustainable community design, and climate
resiliency. Coordination and collaborative efforts with federal, state, tribal, and local entities is a vital
part of these response and recovery efforts.

Adapting to this impact will be dependent on effective disaster risk management and proactive disaster
mitigation actions to incorporate climate change considerations into such things as permitting and
infrastructure funding.

Climate change impacts may threaten contaminated sites. Temperature extremes, heavy
precipitation events and wildfires may threaten contaminated sites in Region 8 and the remedies put
in place to cleanup and prevent releases of hazardous substances. Region 8's Superfund Program
may need to alter chemical containment strategies, as well as monitoring and sampling protocols on
sites. EPA Headquarters has been developing new protocols for addressing the impacts of climate
change.

The Site Assessment program is required to evaluate sites based on criteria established in the Hazard
Ranking System (HRS). Currently, the HRS rule does not consider factors associated with climate
change to determine if a site is eligible for placement on the National Priorities List (NPL).

As the program has limited capacity, the Site Assessment program could prioritize evaluating sites that
may be impacted by extreme climate events and wildfires. Furthermore, the program could refer sites to
the EPA removal program or state cleanup programs based the potential for releases of hazardous
substances due to possible extreme climate events and wildfires.

Climate change may impact EPA Region 8's preparedness and homeland security programs.

EPA has several roles related to preparedness. Fundamentally, Region 8's preparedness program is
focused on reducing the impacts from oil and/or hazardous substance incidents by coordinating with
state, local, tribal, and industrial partners to assess the oil and/or hazardous substance threats in their
jurisdictions or communities and develop contingency plans to mitigate those threats or respond if a
release/discharge should occur. This work is done through a mix of education, partnership, training
and exercises, facility inspections, and contingency plan development.

Environmental changes prompted by climate change could result in increased requests or demand for
education, training and/or exercises, contingency planning and assistance, or even relocation of
industrial facilities into or out of the region, changing the preparedness needs to communities on a large
scale.

Heavy precipitation events, floods, drought, extreme temperatures, and wildfires may threaten the
treatment, storage and/or disposal of hazardous and non-hazardous waste. These events may lead
to a loss of electrical power, impede access, and interrupt operations of facilities that treat, store, and
dispose of waste. Landfill and recycle capacity may be insufficient to handle surges in hazardous and
municipal wastes from extreme weather events and wildfires.

Page 22 | 53


-------
U.S. Environmental Protection Agency Region 8

Climate Adaptation Implementation Plan

In the event of such extreme events, the Region 8's RCRA Branch would work closely with the Region
8 states, who are all authorized to implement the RCRA solid and hazardous waste requirements, to
respond to and adapt to the waste-related challenges. The RCRA Branch, in conjunction with authorized
state programs, may need to work with treatment, storage, and disposal facilities (TSDFs) to alter
chemical containment strategies to ensure protection of groundwater and adjacent sites. The RCRA
Branch may need to help authorized states implement emergency permitting activities or adjust permit
requirements to address current and future climate impacts. Adapting to this impact will largely depend
on available funding and resources, but the RCRA Branch, in cooperation with the authorized states,
could help TSDFs prepare for extreme events, thereby potentially mitigating impacts.

Enforcing Environmental Laws and Ensuring Compliance

Climate change may affect environmental monitoring and sampling in various media. Heavy
precipitation events, floods, and wildfires, as well as other extreme weather events such as severe winds
and tornados, could cause damage to Region 8's environmental monitoring equipment and prevent
access to sampling locations. Additionally, increased air and water temperatures, and the earlier timing
of spring events like snowmelt and runoff, could affect data quality and the baselines on which they rely.
Environmental sampling methods and strategies may also be compromised and require modifications.
These impacts may also require monitoring for a suite of chemicals not typically analyzed. Adapting to
this impact may require a shift in resources and funding.

U.S. Environmental Protection Agency Region 8	Climate Adaptation Implementation Plan

Chaptei 1 11 limate Adaptation ' «¦ > .1 		i-J Pi i- >i ity Actions

3.1	Background

Goal 1 of EPA's FY 2023-2026 Strategic Plan is to "Tackle the Climate Crisis," and includes the
three objectives listed below that address the priorities found in E.O. 14008.

•	Objective 1.1: Reduce Emissions that Cause Climate Change

•	Objective 1.2: Accelerate Resilience and Adaptation to Climate Change Impacts

•	Objective 1.3: Advance International and Subnational Climate Efforts

The priority actions outlined in Region 8's Climate Adaptation Implementation Plan will assist EPA
in achieving Objective 1.2 of its strategic plan, with co-benefits assisting with the broader
achievement of Goal 1.

Region 8 has identified priority actions that can be accomplished concurrent with or as a part of its
ongoing activities, or as additional resources become available. Some priority actions will require
"national-level" action before the Region can address the priority and are noted as such below. By
listing an action as a priority, the Region is not making a commitment to take or complete that action,
or to take or complete it by a particular point in time.

Region 8 priority actions are aligned with the five priorities listed below that are identified in EPA's
2021 Agency-wide Climate Adaptation Action Plan.

•	Priority 1: Integrate climate adaptation into EPA programs, rulemaking processes, and
enforcement activities.

•	Priority 2: Consult and partner with states, tribes, territories, local governments, environmental
justice organizations, community groups, businesses, and other federal agencies to strengthen
adaptive capacity and increase the resilience of the nation, with a particular focus on
advancing environmental justice.

•	Priority 3: Implement measures to protect the agency's workforce, facilities, critical
infrastructure, supply chains and procurement processes from the risks posed by climate
change.

•	Priority 4: Measure and evaluate performance.

•	Priority 5: Identify and address climate adaptation science needs.

3.2	Monitoring and Eiva.lua.ting Performance

There are three long-term performance goals within EPA's Strategic Plan that aim to measure the
Agency's progress in meeting Objective 1.2, Accelerate Resilience and Adaptation to Climate Change
Impacts.

•	By September 30, 2026, implement all priority actions in EPA's Climate Adaptation Action
Plan and the 20 National Program and Regional Climate Adaptation Implementation Plans to
account for the impacts of climate change on human health and the environment.

•	By September 30, 2026, assist at least 400 federally recognized Tribes to take action to
anticipate, prepare for, adapt to, or recover from the impacts of climate change.

Page 24 | 53


-------
U.S. Environmental Protection Agency Region 8

Climate Adaptation Implementation Plan

•	By September 30, 2026, assist at least 450 states, territories, local governments, and
communities, especially communities that are underserved and disproportionately at risk from
climate change, to take action to anticipate, prepare for, adapt to, or recover from the impacts
of climate change.

Region 8's priority actions, as well as other regionally-led assistance activities, will assist EPA
achieve the three Agency-wide climate adaptation long-term performance goals.

Region 8 will evaluate its climate change adaptation activities to assess progress toward
mainstreaming climate change adaptation into programs, policies, rulemaking processes, and
operations. Based on lessons learned about the most effective climate change adaptation strategies,
Region 8 can adjust its approach.

Some metrics exist that will enable Region 8 to measure the results of its activities and others will
need to be developed over time. In general, these metrics will reflect:

•	changes in knowledge (e.g., number of staff/partners taking formal training to increase their
awareness of the importance of adaptation planning);

•	changes in behavior (e.g., increases in the use of decision support tools to integrate climate
adaptation planning into activities such as infrastructure planning decisions); and

•	changes in state/condition (e.g., changes in the ability of communities to withstand more frequent
and intense storm events and avoid, for example, combined sewer overflows).

Region 8 recognizes that the integration of climate adaptation planning will occur over time. This will
happen in stages, and measures should reflect this evolution. The earliest changes in many programs
may be changes in knowledge and awareness, followed by changes in behavior and the use of
adaptation tools, and then implementation of projects that build adaptive capacity and lead to changes
in state and condition.

3.3 EPA Region 8 Climate Adaptation Goals

Region 8's climate adaptation work aims to achieve the five overarching goals listed below.

•	Planning and Implementation: Strengthen climate change adaptation across Region 8
programs through planning, evaluation, and coordination within programs, across programs,
and in concert with EPA headquarters and other federal agencies.

•	Strengthen Internal Adaptive Capacity: Strengthen resilience and adaptive capacity of
Region 8 programs, workforce, and infrastructure to climate change impacts and identified
program vulnerabilities through enhanced technical assistance, training, and preparedness
activities.

•	Strengthen Adaptive Capacity of Our Partners: Strengthen resilience and adaptive capacity
of Region 8 partners, including Region 8 states, Tribes, communities, the general public, and
other federal agencies, to climate change impacts through enhanced technical assistance and
training.

Page 25 | 53


-------
U.S. Environmental Protection Agency Region 8

Climate Adaptation Implementation Plan

•	Research, Data, and Integration: Promote, foster, and integrate climate change impacts and
climate adaptation research into Region 8 programs with a focus on the latest science, and
improved data collection and analysis.

•	Outreach and Education: Work within EPA and with external partners to review, compile,
and develop materials for Region 8 stakeholders, especially at-risk populations, on the impacts
of climate change in our Region and opportunities to adapt to a changing climate.

Climate adaptation and financial mechanisms. Incorporating climate adaptation considerations into
EPA's financial mechanisms is a priority for the Agency as a whole. Financial mechanisms may include
grants (competitive and non-competitive), cooperative agreements, interagency agreements, loans,
implementation of Infrastructure Investment and Jobs Act (IIJA, or Bipartisan Infrastructure Law [BIL])
funds, and contracts.

Region 8 will take steps to ensure the outcomes of infrastructure investments using BIL funds are
resilient to the impacts of climate change. Region 8 will explore opportunities to integrate climate
change considerations into its financial assistance programs in order to expand support for projects that
increase climate resilience while delivering co-benefits for public health, the mitigation of greenhouse
gases, and the reduction of other pollution. Region 8 will also provide technical assistance to recipients
of BIL funds to help them make climate smart infrastructure investments.

BIL is a historic investment in the water infrastructure improvements, pollution cleanup initiatives, and
workforce opportunities necessary to transform communities around the country. Much of the federal
assistance provided through BIL will scale up EPA's existing grant and loan programs, such as the State
Revolving Fund Programs and Brownfields Grants. It will also be delivered through the creation of new
low-interest financing programs, primarily for tribes and rural or disadvantaged communities. With this
significant influx of capital from BIL, it will be more important than ever for EPA - and our state, tribal,
and local partners - to invest in resilient infrastructure projects that withstand climate change for
decades to come.

EPA's National Program and Regional Offices will work through the programs that received BIL
funding to encourage resilient infrastructure outcomes across the country. Internally, EPA is taking steps
to consider how its policies, operations, and program activities can be better aligned to accelerate
resilient infrastructure projects, with an emphasis on the most vulnerable communities. EPA will take
steps to ensure that its financial assistance programs support resilient infrastructure investments that
consider anticipated climate change impacts. It will also be critical that EPA's technical assistance
programs are readily accessible to stakeholders as they take intermediate steps to make climate-informed
infrastructure investments. EPA will support its external partners by providing technical assistance
opportunities for BIL-funded projects to help build their adaptive capacity. Consistent with the Agency's
Climate Adaptation Action Plan, EPA's Offices will seek opportunities to engage with other federal
agencies, external partners, and federal funding recipients to achieve climate-resilient infrastructure.

Climate Adaptation Implementation Plan

4.1	Training Approach

A central element of Region 8's efforts to adapt to a changing climate will be to increase staff
awareness of how climate change may affect their work by providing them with the necessary data,
information, and tools. Additionally, states, Tribes, and local communities share responsibility for
protecting human health and the environment. Partnerships with EPA are at the heart of this.

Working in concert with EPA National Program Offices, National Support Offices, and other
Regional Offices will prove imperative as training is developed that tests and enhances climate
adaptation knowledge at general and program-specific levels. These partnerships will be critical for
efficient, effective, and equitable implementation of climate adaptation training, which will evolve
over time.

Region 8's training approach includes the key elements listed below.

•	Ensure that technical staff and their partners have access to training on the importance of climate
adaptation, and how they can incorporate climate adaptation considerations into their work.

•	Ensure that technical staff and their partners have access to specific approaches, data, and tools for
integrating climate adaptation into decision-making processes.xl

•	Develop a Region 8 climate adaptation communication strategy to enhance external climate
change communication, which may include state and tribal partners, municipalities, industry, the
public, and other relevant parties. The communication strategy will include but is not limited to
information on climate change impacts and risks, and the programs, tools, and resources available
to stakeholders to enhance adaptation and resiliency (which may include elements of the various
climate adaptation training modules found below).

•	Work with other federal agencies to enhance understanding of climate change, leverage collective
knowledge about climate adaptation planning, reduce duplication, and avoid conflicting efforts,
which may include training.

4.2	Climate Adaptation Training Modules

EPA National Program Offices and National Support Offices will be developing and/or updating
climate adaptation training modules to support Goal 1 of EPA's Strategic Plan. Currently, the training
modules will be rolled out as follows. Once available, Region 8 will utilize various methods to distribute
and deliver the EPA Headquarters-developed training modules.

Chaptei imate Adaptation Science Needs

Climate Adaptation Implementation Plan

Region 8 has identified the following region-specific areas where additional support is needed to assess
climate impacts and build resilience. Region 8's proposed science needs are organized by
division/office. The following needs were identified as part of the development of this planning
document and are subject to change, as well as growth as new science needs identified. This would take
place in future fiscal years as Region 8 implements its priority actions and engages in further
conversation with stakeholders and partners around the topic of climate adaptation.

Air and Radiation Division

•	To study whether the PM2.5 NAAQS is the best forecasting metric for wildfire smoke or whether
a separate metric should be added to the Air Quality Index (AQI) to better reflect the immediate
health impacts of wildfire smoke, which often contains significant levels of air toxics in addition
to nitrogen oxides (NOx), volatile organic compound (VOC), carbon monoxide (CO), and PM
emissions.

•	To conduct research on wildfire emissions through greenhouse gas quantification to address and
build resilience in both the rural and urban greenhouse gas adaptation sector. This research will
build capacity in the Region 8 Air and Radiation Division under the Clean Air Act and the Paris
Climate Agreement statutory authorities.

•	To conduct research on VOC emissions from consumer products through public awareness and
outreach tools to help communities reduce emissions and adapt and build resilience. This
research will build capacity in Region 8 Air and Radiation Division under Clean Air Act
statutory authority.

Laboratory Services and Applied Sciences Division

•	To research the beneficial reuse of produced water to improve drought resiliency across the arid
west. Local, state, and federal governments are considering the expanded use of alternative water
sources (e.g., industrial wastewater) to replace or augment fresh water as a direct result of
climate change and increased water demand. EPA's National Water Reuse Action Plan (WRAP)
identifies produced water as one of five alternative water sources being explored. The goal of
this research is to identify the potential toxicity of treated and untreated produced water and to
identify which constituents are contributing to toxicity. Understanding potential toxicity will
inform appropriate use and/or treatment that may be needed for various uses of produced water
including irrigating crops, livestock consumption, roadway dust suppression, and discharge to
surface water.

•	To conduct research to address increased acid rock and acid mine drainage (ARD/AMD) due to
increased oxidation rates and summer air temperatures to improve remedial decision making at
mine sites. This research will build capacity in the Superfund program under CERCLA statutory
authority.

P a g c 44 | 53


-------
U.S. Environmental Protection Agency Region 8

Land and Chemical Redevelopment Division

•	To research the beneficial use of electric arc furnace (EAF) slag. Industrial sectors including the
steel industry generate hundreds of millions of tons of secondary materials each year that are sent
for disposal. Secondary materials are any materials that are not the primary products from
manufacturing and other industrial sectors. Appropriate beneficial use of secondary materials can
encourage greater resource sustainability by returning valuable resources back into the circular
economy, while also keeping them out of landfills.

Office of the Regional Administrator

•	To conduct research on the impacts of climate change in tribal communities to help inform how
they can best utilize their resources to build resiliency. Impacts to Tribes include, but are not
limited to, flooding, droughts, crop failure, the destruction of culturally significant sites, and
impacts to drinking water and/or recreational areas (e.g., due to HABs).

•	To conduct research on air quality through PM2.5 air monitoring to address climate adaptation in
rural, plains and mountainous communities, and build resilience in environmental and public
health sectors. This research will build capacity in the Environmental Justice, Tribal Affairs
Branch, and Clean Air programs under the Clean Air Act statutory authority.

Superfund and Emergency Management Division

•	To conduct research on impacts of climate change on superfund sites (including remedy
selection and resilience) to address impacts of climate change and extreme weather (fires,
floods, etc.) and build resilience in the Superfund cleanup sector. This research will build
capacity in the superfund program under CERCLA statutory authority.

Water Division

•	To research climate-related shifts in HABs, including the uptake of algal toxins into plant and
animal tissue, use of social and citizen science to achieve positive outcomes in reducing excess
nutrients, and understanding of the extent and impact of benthic cyanobacteria in Region 8.

•	To coordinate the development of a long-term regional water quality monitoring network to
assess long term trends in climate sensitive indicators and as a basis for water quality criteria
development or refinement.

•	To research and estimate climate change-related shifts in the magnitude, duration, and timing of
the flow regime and plan ways to incorporate these shifts into Water Division work (e.g., 7Q10,
TMDL critical conditions).

specific programmatic vulnerabilities resulting from climate change to which the Region will likely need
to adapt. EPA Region 8 is committed to building not only our own adaptive capacity but also the
adaptive capacity of our partners and stakeholders.

EPA's leadership and commitment to building the nation's adaptive capacity are vital to its mission of
protecting human health and the environment.

Appendix A. Stakeholder and Partner Engagement

Climate Adaptation Implementation Plan

Region 8 conducted two periods of stakeholder and partner engagement during the development of its
Climate Adaptation Implementation Plan.

Early Engagement on EPA's Climate Adaptation Planning Process and Climate Impacts
In order to engage early in the planning process, Region 8 met with stakeholders and partners to raise
awareness of E.O. 14008, EPA's process for updating its Climate Adaptation Action Plan, and the
forthcoming efforts by EPA regional and program offices to update or develop respective Climate
Adaptation Implementation Plans. During the second half of calendar year 2021 and into early 2022,
Region 8 used standing meetings, as well as ad hoc meetings and conversations, to reach a variety of
stakeholders and partners. During these engagements, Region 8 shared a draft Table 2. Climate Change
Impacts in EPA Region 8 and asked four discussion questions.

1.	What are your thoughts on the draft updated list of climate change impacts in EPA
Region 8?

2.	Are there any impacts you would suggest adding or deleting?

3.	What might be the effects of these impacts on your programmatic work?

4.	Do you have any other comments or suggestions related to the update of EPA Region 8's
Climate Adaptation Implementation Plan?

Audiences for early engagement included but were not limited to Tribal Environmental Directors /
Region 8 Regional Tribal Operations Committee (RTOC), Region 8 State Environmental Directors,
Region 8 State Oil and Gas Directors, Region 8 State Air Directors, Region 8 State Water Directors,
Region 8 Agriculture Commissioners, U.S. Department of Agriculture (USDA) Natural Resources
Conservation Service (NRCS), Four Corners Air Quality Group (4CAQG), and Region 8 pesticide
directors.

Engagement on Draft Region 8 Climate Adaptation Implementation Plan

During the months of May and June 2022, Region 8 prepared and implemented a stakeholder and
partner engagement strategy to share key and relevant elements of the draft Region 8 plan with various
audiences.

Region 8 hosted two identical listening sessions in the month of June 2022, open to the public and
targeting non-governmental organizations, community groups, and academia.

Engagement with Region 8 Tribes was coordinated both at the regional level and in concert with EPA
Headquarters' Office of International and Tribal Affairs (OITA) by offering tribal consultation as well
as engagement opportunities through a national listening session and through the Region 8 RTOC.

Engagement with Region 8 state and local governments was coordinated through existing networks such
as State Environmental Directors and other state media directors. A dedicated session for state
government was also held at the request of the State Environmental Directors. Local government

engagement was coordinated through meetings with umbrella organizations and local government
attendance at the Region 8 listening sessions. A national listening session was also held for state and
local government associations.

A PDF of the draft Region 8 plan was posted to EPA's Climate Adaptation Plan website

(www.epa.eov/climate-adaptation/climate-adaptation-plan) during this period of external engagement.
