Preface
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.
Scientific evidence demonstrates that the climate is changing at an increasingly rapid rate, outside the
range to which society has adapted in the past. These changes can pose significant challenges to the
EPA's ability to fulfill its mission. The EPA must adapt to climate change if it is to continue fulfilling its
statutory, regulatory and programmatic requirements. The Agency is therefore anticipating and planning
for future changes in climate to ensure it continues to fulfill its mission of protecting human health and
the environment even as the climate changes.
In February 2013, the EPA released its draft Climate Change Adaptation Plan to the public for review
and comment. The plan relies on peer-reviewed scientific information and expert judgment to identify
vulnerabilities to EPA's mission and goals from climate change. The plan also presents 10 priority
actions that EPA will take to ensure that its programs, policies, rules, and operations will remain effective
under future climatic conditions. The priority placed on mainstreaming climate adaptation within EPA
complements efforts to encourage and mainstream adaptation planning across the entire federal
government.
Following completion of the draft Climate Change Adaptation Plan, each EPA National Environmental
Program Office, all 10 Regional Offices, and several National Support Offices developed a Climate
Adaptation Implementation Plan to provide more detail on how it will carry out the work called for in the
agency-wide plan. Each Implementation Plan articulates how the office will integrate climate adaptation
into its planning and work in a manner consistent and compatible with its goals and objectives.
Taken together, the Implementation Plans demonstrate how the EPA will attain the 10 agency-wide
priorities presented in the Climate Change Adaptation Plan. A central element of all of EPA's plans is to
build and strengthen its adaptive capacity and work with its partners to build capacity in states, tribes, and
local communities. EPA will empower its staff and partners by increasing their awareness of ways that
climate change may affect their ability to implement effective programs, and by providing them with the
necessary data, information, and tools to integrate climate adaptation into their work.
Each Program and Regional Office's Implementation Plan contains an initial assessment of the
implications of climate change for the organization's goals and objectives. These "program vulnerability
assessments" are living documents that will be updated as needed to account for new knowledge, data,
and scientific evidence about the impacts of climate change on EPA's mission. The plan then identifies
specific priority actions that the office will take to begin addressing its vulnerabilities and mainstreaming
climate change adaptation into its activities. Criteria for the selection of priorities are discussed. An
emphasis is placed on protecting the most vulnerable people and places, on supporting the development
of adaptive capacity in the tribes, and on identifying clear steps for ongoing collaboration with tribal
governments.
Because EPA's Programs and Regions and partners will be learning by experience as they mainstream
climate adaptation planning into their activities, it will be essential to evaluate their efforts in order to
understand how well different approaches work and how they can be improved. Each Implementation
Plan therefore includes a discussion of how the organization will regularly evaluate the effectiveness of
its adaptation efforts and make adjustments where necessary.
-------
The set of Implementation Plans are a sign of EPA's leadership and commitment to help build the
nation's adaptive capacity that is so vital to the goal of protecting human health and the environment.
Working with its partners, the Agency will help promote a healthy and prosperous nation that is resilient
to a changing climate.

I. Regional Climate Change Adaptation (RCAP) Executive
Summary
Climate change and its associated impacts to air, water and waste systems are challenging EPA's mission
of protecting the environment and public health. One impact, increasing extreme precipitation1, has
already taken a large toll on New England's environment. In August 2011, tropical storm Irene dumped
three to five inches of rain throughout Vermont over two days, with many areas receiving more than
seven inches. Extensive flooding caused millions of dollars of damage to infrastructure. Wells and
public water systems were submerged and contaminated with chemicals and pathogens, degrading safe
drinking water supplies.2
Figure 1: Route 107 Stockbridge, VT, August 29, 20113
Two months later in 2011, an unseasonably early
October snowstorm dumped one to two and a half
feet of snow, felled trees and resulted in
significant power outages across the New
England region. As shown in Figure 2, increased
usage of local generators and wood stoves in
response to the loss of power led to unhealthy
ambient air conditions particularly for sensitive
groups.4
For over 40 years, EPA New England has been
protecting the region's environment and public
health through the implementation of air, water
and waste programs. EPA New England has
been working on climate mitigation, greenhouse
gas reduction strategies since 2000 and has had a multi-media Global Climate Change Network that has
educated EPA staff and worked on climate mitigation and adaptation since 2009.
In 2009, President Obama established an Interagency Figure 2: Daily Peak PM2.5 Air Quality index5
Climate Change Task Force. He called on that task
force to develop recommendations for adapting to
climate change with the goal of promoting a healthy
and prosperous nation resilient to climate change.
The Task Force's 2010 report recommended that
every Federal Agency develop a Climate Change
Adaptation Plan. EPA's national Climate Adaptation
Plan was developed and released for public comment
on February 8,2013. In 2011, EPA's Administrator
Lisa Jackson asked that all EPA regional and
program offices develop climate adaptation plans to
detail how we will carry out the work in the agency-
wide plan, taking into account the impacts on EPA's
regional mission and operations. In September
2012, EPA New England convened 30 employees knowledgeable in their media programs and asked them
to assess the risks and impacts of climate change that are and will be pertinent to the region's mission and

responsibilities, and to develop a plan of action to address these risks and impacts within the region.
This draft regional climate adaptation plan outlines existing conditions in New England and how we will
incorporate the challenges of climate change into our programs and operations. Based on global, regional
and state specific scientific research and modeling projections, EPA New England staff determined the
vulnerabilities for our programs and facilities and identified priority actions for both the chronic and
episodic impacts of climate change.
The major chronic impacts reviewed include:
• Heat - Since 1970 the average annual temperature rose 2°F and the average winter temperature
4°F6
• Extreme Precipitation - Over the past 50 plus years the Northeast has seen a 71% increase in the
amount of precipitation falling in very heavy events (defined as the heaviest 1% of all daily
events).7
• Sea Level Rise - Global sea levels are projected to rise 12 to 48 inches by 2100, depending in
large part on the extent to which the Greenland and West Antarctic Ice Sheets experience
significant melting.8
The episodic impacts include:
• Flooding - In August 2011, tropical storm Irene hit New England. In Vermont alone, recovering
from the widespread damage and destruction is expected to cost between $700 million and $1
billion dollars.9
• Ocean Storm Surge - In October 2012, Super Storm Sandy caused a storm surge of 9.2 ft. in NY
City10. The coastal areas of CT and RI were also significantly affected. According to The
Boston Harbor Association report, if the storm had hit Boston 5.5 hours earlier on the high tide it
would have caused a 5 foot storm surge that would have flooded 6.6% of Boston.11
For this plan, regional programs were reviewed and the vulnerabilities of these programs to one or more
of the above impacts were determined. For example, an increase in heat could increase the number of
unhealthy ozone days.12 Priority actions to address the vulnerabilities were then drafted. Over 100
actions were identified. Each priority action was evaluated based on its ability to reduce risk, whether the
action would protect a critical asset, whether it would be easy to implement (i.e., whether it would be
"low-hanging fruit"), whether it would leverage other larger efforts, EPA's unique role and capacity, the
time frame to accomplish and the funding needed.
The final section of the plan lays out how these actions will be incorporated into the region's existing
programs and how we will measure our progress. For instance, the Agency works with the states and
tribes on an annual basis to determine activities that EPA will fund. We will work with the states and
tribes to incorporate climate adaptation into those activities. Additionally, the Region has a Global
Climate Change Network (GCCN) made up of staff and managers from every office in the Region and
each year the GCCN develops a strategy for activities it expects to accomplish for both climate change
mitigation and adaptation. The priority actions identified in this plan will be incorporated into the
GCCN strategy on an annual basis.
In order to gather stakeholder input, we have held ten webinars with the air, water and waste interstate
organizations whose members come from the six New England states air, water and waste environmental
agencies, New England nongovernmental organizations, the New England Environmental Business
13
-------
Council, tribal leaders, tribal environmental managers and tribal historic preservation officers. All of
their input has been incorporated into this plan.
EPA New England will continue to evaluate the science and impacts of climate change and will update
the vulnerabilities and priority actions for our programs in order to reduce risk to New England's health
and environment.

II. Existing and Forecasted Conditions
Forecasted Climate Change Impacts in New England of Concern for EPA's Regional Mission and
Operation
New England is well known for its varying seasons, rocky coastline,
extensive beaches, and mix of both urban and rural settings. Over
the last several decades, New England has experienced noticeable
changes in its climate. New England is and will be uniquely
impacted by climate change due to its population distribution,
geography, seasons and weather patterns. Below is a summary of
existing conditions and forecasts for New England climate change
impacts. As indicated by the references, a key source of existing
and forecasted information is taken from the 2009 publication by
the United State Global Climate Research Program (USGCRP),
Global Climate Change Impacts in the United States13 as well as
from the 2014 publication Northeast Chapter of Climate Change
Impacts in the United States: The Third National Climate
Assessment14.
. Where appropriate, we have also included information used by
New England States when considering climate change impacts
within their respective states.

New England has a population of over 14 million, with a large portion of the population located along a
coast that spans approximately 6,100 miles. From 1960 to 2008, Maine and New Hampshire had the
highest increase in the share of population in coastline
counties.15 From 2010 to 2030, New England's population is
projected to increase by eight percent.16

Demographics
According to the Census, the population in the nation is aging and New England has a larger proportion
of the elderly and baby boomers (14.4%) than the rest of the nation (13%).17 Four of New England's six
states are more densely populated than the nation's average.18 Rhode Island and Massachusetts are the
second and third most densely populated states with 91% of its population in urban areas; and
Connecticut is fourth with as much as 88% of its population in urban areas.19

Increases in Air Temperature
Since 1970, the average annual temperature in the Northeast has risen by 2°F and the average winter
temperature has increased by 4°F.20 This trend is projected to continue. As shown in Figure 3, by 2100
New Hampshire's summers could be as warm as North Carolina's summers are today.21
. . _. , . . _ ... Figure 4: Extreme Heat in Boston22
As shown in Figure 4, over the same period, Boston is projected
to experience an increase in the number of days reaching 100°F -
from an average of one day per year between 1961 and 1990 to as
many as 24 days per year by 2100.22 Under a higher emissions
scenario identified by the Intergovernmental Panel on Climate
Change (TPCC), Hartford, CT could see as many as 30 days per
year with temperatures reaching 100°F.23 These rising
temperatures have potential impacts on public health, ranging
from heat-related stress to infectious diseases. This is further
explained in Public Health Impacts below.
General warming is expected, in New England. However, the
Houlton Band of Maliseets, a federally-recognized tribe on the
Meduxnekeag River in Maine, cite a reference that suggests that a
narrow strip along the eastern Maine coast may not experience a
general warming trend. The reference states that in the past
"twice daily tidal mixing of the Gulf of Maine brought deep, cold
water to the surface, and southwesterly current along the coast
brought cool temperatures, often accompanied by fog." The
reference states that this effect may continue into the future for
this small geographic area.24 This supposition was not included in the recently published Northeast
Chapter of Climate Change Impacts in the United States: The Third National Climate Assessment25
Seasonal Shift
Increased air temperatures have already resulted in shifts in the seasonal patterns in New England and
that trend is projected to continue. When there is an extended warm period in either late winter or early
spring, premature leaf-out or bloom can occur. If this is followed by a frost event, damage to plants can
occur. This occurred in 2007 and in 2012 in the northeast, when apple and other fruit crops were hard
hit.26
In the winter, more precipitation is falling as rain rather than snow, and as a result, there is a reduced
snowpack.27 A 2011 Vermont Agency of Natural Resources group of publications noted that the timing
and form of precipitation affects the quantities of water stored in surface waters and aquifers, potentially
affecting the availability of water for human use.28 The publications also state that in the spring, the ice
on lakes and rivers melts earlier, resulting in earlier peak river flows. The publications forecast that,
combined with reduced snowpack, earlier snow melt is anticipated to lead to an increase in frequency of
summer droughts.29 In addition, both the Commonwealth of Massachusetts and Vermont note that the
duration, timing, and frequency of seasonal precipitation and flooding are changing, resulting in impacts
on the hydrologic cycle and aquatic habitats and the organisms that depend on them, including migratory
fish and aquatic insects.30'31 In Vermont, they are concerned that summer low flows from increased
drought frequency may also reduce aquatic habitats and make them more isolated, and that lower flows
may lead to higher water temperatures, reducing the amounts of dissolved oxygen. Lastly, Vermont

Impacts in the United States.20

notes that all of these changes have the potential to shift prevalent fish species and reduce cold-water fish
populations, potentially allowing new species to gain competitive advantages.32
In a Climate Change Adaptation White Paper Series, Vermont stated that a changing climate may cause
species to shift their distribution on the landscape to follow the presence of preferred or essential
habitats.33 In this paper, Vermont identified the invasion of Asian long-horned beetle as well as woolly
adelgid while Maine has seen Asian shore crab and Eurasian water milfoil.34 Wooly adelgid is an insect
that is native to Japan that threatens Eastern Hemlock trees.35
Figure 5: Percentage Change in Very Heavy Precipitation3

Changes in Precipitation Patterns
Warmer temperatures increase the rate of
evaporation of water into the atmosphere, in
effect increasing the atmosphere's capacity to
"hold" water.36 Increased evaporation may dry
out some areas and increase precipitation in
other areas. In fact, drought and increasing
heavy precipitation are not mutually exclusive
and may even happen in the same locations.
While winter precipitation is projected to
increase along with temperature, little change is
projected for summer rainfall.37 Combined with
greater evaporation from higher temperatures
and earlier winter and spring snowmelt, the
summer and fall drought risk for the Northeast
is projected to increase.38 At the same time, in
the Northeast, heavy precipitation events have
increased more dramatically over the past 60
years than in the rest of the country. As shown
in Figure 5, in the northeast, the amount of
precipitation falling in very heavy precipitation
events from 1958 to 2011 has increased by
71%.39 This increasing trend is projected to
continue into the future. The Commonwealth of Massachusetts projects that rainfall during the wettest
five days of each year will increase 10% by mid-century and by 20% by 2100.40
Sea Level Rise
Since 1900, sea level in the Northeast has risen by approximately 12 inches.41 Global sea levels are
projected to rise 12 to 48 inches by 2100, depending in large part on the extent to which the Greenland
and West Antarctic Ice Sheets experience significant melting.42 Sea level rise along most of the coastal
Northeast is expected to exceed the global average rise due to local land subsidence, with the possibility
of even greater regional sea level rise if the Gulf Stream weakens as some models suggest.43 Two New
England States — New Hampshire and Massachusetts - cite a 2008 study by Pfeffer, J. T. et al44 that
includes the contribution to sea level rise from the melting of the Greenland and West Antarctic ice
sheets that suggests that sea levels could rise as much as 79 inches by 2100.45 The City of Boston
projects that the Boston's sea level rise will range from 24 to 72 inches by the end of the century,
depending on how quickly the ice in Greenland and Antarctica melt.46
The map shows percent increase in the amount of precipitation falling in very
heavy events (defined as the heaviest 1% of all daily events) from 1958 to 2011
for each region.37

The Third National Climate Assessment.37

-------
In June of 2012, a USGS study stated that between 1950-1979 and 1980-2009, sea levels between Cape
Hatteras and Boston rose approximately three to four times faster than the global average.47 Taking
subsidence at a rate of six inches per century into account, the state of Rhode Island Coastal Resources
Management Council has begun to plan for a 36 to 60 inch sea level rise by 2100 and they have codified
their projection in state regulations.48 Other states, such as Massachusetts, also cite subsidence as a
potential factor influencing the magnitude of local sea level rise.49
Increased Flooding and Storm Surges
In the past 50 years, there has been an increase in flooding in New England, both in coastal and inland
areas threatening manmade and natural infrastructure. New England's industrial development in the 19th
century was along its rivers where the water could be used as a source of energy. Many of these facilities
still exist today and are vulnerable to river flooding. Between 1955 and 1999, floods accounted for
$16.97 million in damage annually in Vermont alone.50 In 2011, tropical storm Irene dumped three to
five inches of rain throughout the state over two days, with many areas receiving more than seven
inches.51 The extensive flooding caused millions of dollars of damage to Vermont's infrastructure
including damage to 500 miles of road and 200 bridges. The cost of rebuilding this infrastructure is
estimated to be up to 250 million.52 Wells and public water systems were submerged and contaminated
with chemicals and pathogens, thereby affecting safe drinking water supplies.53 A state-wide drinking
water advisory was issued to warn citizens of the possibility of harmful chemicals or bacteria in their
flooded wells. Approximately 30 public water systems issued "boil water" notices, affecting
approximately 16,590 people. Seventeen municipal wastewater treatment facilities also reported
compromised operations54and private water supply wells were also affected. The Vermont Department
of Health distributed over 3,000 free bacterial sample kits for homeowners to test their wells. Of the test
kits returned to the Department for testing, 37% were positive for total coliform (of the 37, 8% were
positive for E.coli). Lastly, hazardous waste spills increased by a factor of fourteen during the first week
after tropical storm Irene.55 Projecting forward, Vermont anticipates the increasing probability of high-
flow events could be as high as 80%.56
Coastal flooding is also an issue for New England. It is expected that the combination of a projected
increase in heavy precipitation and sea level rise will lead to more frequent, damaging floods in the
Northeast.57 Less winter precipitation falling as snow and more as rain will also increase the number and
impact of flooding events as the frozen ground is unable to absorb the winter rain. Sea level rise, storm
surges, hurricanes, erosion, and the destruction of important coastal ecosystems will likely contribute to
an increase in coastal flooding events, including the frequency of current "100-year flood" levels (severe
flood levels with a one-in-100 likelihood of occurring in any given year). Figure 6 shows the current
Federal Emergency Management Agency 100-year flood zone (hatched darker blue) as well as the extent
of the projected 100-year flood zone in 2100 (lighter blue) for the waterfront/Government Center area of
Boston under a "higher-greenhouse gas emissions scenario" used by the Northeast Climate Impacts
Assessment (NECIA) in a report titled Climate Change in the U.S. Northeast5* What is now considered
a once in a 100-year coastal flood in Boston is expected to occur, on average, as frequently as every two
to three years by mid-century and once every other year by late-century - under either emissions scenario
identified by NECIA. Cumulative damage to buildings and building contents, as well as the associated
emergency costs, could potentially be as high as $94 billion between 2000 and 2100 in Boston,
depending on the sea level rise scenario and which adaptive actions are taken.59

Increase in Fresh and Ocean Water Temperature and Acidification
In addition to changes in the level of the sea, the physical and chemical properties of the ocean are
changing. As the air temperature warms, it warms the ocean. Globally, sea surface temperatures have
been higher during the past three decades than at any other time since reliable observations began in
1880.60 Warmer fresh and salt waters hold less dissolved oxygen making "hypoxia"2 more likely,
fostering harmful algal blooms, and changing the toxicity of some pollutants.61
The pH level of seawater has decreased significantly since 1750, and is projected to drop much more
dramatically by the end of the century if carbon dioxide (CCh) concentrations continue to increase as the
oceans absorb this CCh.62 According to the 2011 Massachusetts' Climate Change Adaptation Report, pH
levels are projected to decrease by 0.1- 0.3 by 2100, making the ocean more acidic.63 As EPA stated in
the draft National Water Program 2012 Strategy: Response to Climate Change^ scientific research over
the last 10 years indicates serious implications of ocean acidification for ocean and coastal marine
ecosystems. In its 2010 report, Ocean Acidification: A National Strategy to Meet the Challenges of a
Changing Ocean, the National Research Council65 concludes that ocean chemistry is changing at an
unprecedented rate due to human-made CCh emissions. The report also states that "while the ultimate
2 Hypoxia occurs when dissolved oxygen declines to the point where aquatic species can no longer survive
19
-------
consequences are still unknown, there is a risk of ecosystem changes that threaten coral reefs, fisheries,
protected species, and other natural resources of value to society." Of particular concern in New England
is the threat that acidification has for shellfish populations, especially soft shelled clams, and research on
this issue is underway in Maine and elsewhere.
Public Health Impacts
Extreme heat events can and have impacted human health. A three-day heat wave (temperatures reaching
triple digits on two days) in Chicago in 1995 led to nearly 700 heat-related deaths.66 The possibility of
similar heat waves are increasingly likely in New England as projections for the number of days per year
over 100°F grow (see Figure 4). In September 2010, Maine experienced a heat wave in which many
schools closed due to excessive heat and the fact that schools do not have air conditioning. During this
heat wave, the National Weather Service issued an advisory warning that "the high heat and humidity
combined with the long duration of the current heat wave would make conditions uncomfortable and
potentially dangerous especially in hot buildings without air conditioning or proper ventilation."67 Since
the hottest days in the Northeast are often associated with high concentrations of ground-level ozone and
other pollutants, the combination of heat stress and poor air quality can pose a health risk to vulnerable
groups: young children, the elderly, and those with pre-existing health conditions including asthma.68
The combination of warmer temperatures and extreme weather events encourages the spread of infectious diseases
in new areas and affects many aspects of human health.69 Changes in vector-borne diseases are already
being seen in the Northeast with Spotted Fever Rickettsiosis, a tick borne infection, reported in 4 of the 6
states. Babesiosis, or animal malaria also carried by ticks may threaten the blood supply. This newly
reportable disease has been growing in the northeast and is now reported in every New England state.70
Suitable habitat for the Asian Tiger Mosquito, which can transmit West Nile and other vector-borne
diseases, is expected to increase in the Northeast from the current 5% to 16% in the next two decades and
from 43% to 49% by the end of the century, exposing more than 30 million people to the threat of dense
infestations by this species.71
Over the last 10 summers from 2004 through 2013, New England has averaged 30 days per year with
unhealthy air for the current ozone standard of 75 parts per billion. In New England, high ozone levels
usually occur between 1:00 and 7:00 pm on hot days from May through September.72 Hot days are
particularly conducive to ground-level ozone formation, and air conditioning loads on such days are often
a major contributor to electricity demand spikes. At the same time, some EGUs called "peaking units"
only operate during periods of peak demand when the electric grid requires maximum generating
capacity, and could be high-emitting sources of nitrogen oxide (NOx) emissions, which are a key
contributor to ground-level ozone formation. Peaking units might lack NOx controls because they have
low emissions on a seasonal basis, even if hourly NOx emissions are high during periods when they are
in use.73 Thus, it is expected that with an increase in the number of days with high temperatures, New
England will see increases in ozone on those days.
Built Environment-Housing and Indoor Air
In the United States, citizens spend over 90% of their time inside with an estimated 70% of that time
spent in their homes. The US Census's American Housing Survey in 2009 reported that nearly 6 million
housing units have moderate to severe physical infrastructure problems.74 The National Center for
Healthy Homes citing this Census study states that the most common problems in American housing are
water leaks from the outside (11%) and inside (8%), roofing problems (6%) and damaged walls (5%).
According to the Census's American Community Survey Summary from 2007-2011, only 14% of the
20
-------
homes in the nation were built before 1939. In New England 28% of the homes were built before 1939.75
These older homes were built prior to many of the new construction codes and may be more susceptible
to structural problems. In addition, the northeast has a higher percentage of multi-family structures; 63%
of family homes in the northeast are single family homes, as opposed to 83% in the United States as a
whole.76 New England housing units also rely more on the use of fuel oil or kerosene. In New
Hampshire, Vermont and Maine over 50% rely on these fuels for heating vs. only 7% in the entire
nation.77 These fuels are delivered by fuel trucks and those deliveries could be disrupted by severe
weather events. All of these factors combined indicate that New Englanders are potentially exposed to
more indoor pollutants than those in other parts of the US.
Adaptation Planning Underway in New England
Because of the susceptibility of New England to climate change impacts, New England federal, regional,
state agencies, and non-government organizations have already begun addressing this issue. New
England states in particular have been out in front of the nation in planning for both climate mitigation
and adaptation. Table 1 summarizes the adaptation efforts of the New England states, and the adaptation
activities are expanded upon below:
• In 2005, the Governor's Steering Committee on Climate Change for Connecticut produced a
Climate Change Action Plan focusing on greenhouse gas emissions. In 2010, the Adaptation
Subcommittee of the Governor's Steering Committee produced a report "The Impacts of Climate
Change on Connecticut Agriculture, Infrastructure, Natural Resources and Public Health,"
detailing the potential impacts of climate change. In 2011, this subcommittee produced a draft
report addressing adaptation strategies in light of identified impacts, "Connecticut Climate
Change Preparedness Plan." This report was finalized in July 2013. In January, 2014, the
Institute for Community Resiliency and Climate Adaptation was created in Connecticut. The
Institute is a collaboration between the University of Connecticut, the state Department of Energy
and Environmental Protection, and the National Oceanic and Atmospheric Administration.
• In Maine, Governor LePage recently created a workgroup entitled "Environment and Energy
Resources Work Group" which consists of state agencies focused on transportation, energy,
fisheries and wildlife, forestry, agriculture and marine resources. The cross-agency effort is
aimed at discussing mechanisms for cross agency partnerships, information sharing, efficiencies
and streamlining. These efforts will provide specific and identifiable tools to assist decision-
makers in preparing for climate change78.
• In 2008, Massachusetts' Global Warming Solutions Act led to the establishment of a Climate
Change Adaptation Advisory Committee that produced a report on adaptation strategies in light of
predicted climate changes for the state. The report, published in 2012, provided conclusions and
recommendations by the committee regarding anticipated climate change and future adaptation
strategies. In addition, the report provides sector-specific impacts and adaptation strategies.
• In December 2007, Governor Lynch of New Hampshire established a Climate Change Policy
Task Force, charging the group with the development of a Climate Action Plan for New
Hampshire. The report was published in March 2009. The final report focused on greenhouse
gas emissions reductions to address climate change but also identified anticipated future impacts
of climate change on various sectors: agriculture, forestry and waste, electric generation,
transportation and land use.
21
-------
• In 2010, Rhode Island's Climate Change Commission was established through the state's Climate
Risk Reduction Act. In November 2012, a progress report was produced; summarizing key
climate risks and vulnerabilities to those risks, identifies existing climate change adaptation
initiatives, and highlights the areas that have yet to be addressed. In addition, in Section 145
"Climate Change and Sea Level Rise" of Rhode Island's Coastal Resources Management
Program, Rhode Island has codified in regulation that future policies, plans, and regulations
proactively plan for and adapt to climate change and sea level rise.79 In addition, the University of
Rhode Island and other collaborators recently launched a website designed to inform the public
about climate change and to help prepare for the changes.80
• From 2010 to 2012, Vermont's Agency of Natural Resources (Vermont ANR) developed a series
of sector-based white papers as part of an initial education effort. Sectors included: agriculture,
water resources, recreation, forestry, public health, public safety, fish and wildlife, and
transportation. Vermont ANR expects to have a vulnerability assessment and adaptation strategy
for Vermont lakes, rivers, forests, and wetlands, including those natural communities and the
organisms that inhabit them in 2013.

In addition to state activity related to adaptation, there are adaptation planning activities occurring at the
municipal level as well. For example, Boston, MA; Cambridge, MA; Portland, ME; Scarborough-Old
Orchard Beach, ME; and several communities in New Hampshire and the Metropolitan Area Planning
Council, a regional planning agency that serves over one hundred cities and town in Metropolitan Boston,
are all engaged in adaptation planning.81 In 2011, EPA New England, in coordination with the Institute
for Sustainable Communities, launched the New England Municipal Sustainability Network (NEMSN),
which fosters peer to peer communication between municipal Sustainability practitioners across the
region on key priorities including climate change adaptation. In December of 2011 the NEMSN
sponsored climate adaptation training for themselves. At the federal level, in 2010, the New England
Federal Partners Climate Workgroup was formed and it includes 17 federal agencies and their staff
including National Oceanographic and Atmospheric Administration (NOAA), EPA, Federal Emergency
Management Agency (FEMA), United States Geological Service (USGS), United States Army Corps of
Engineers (USAGE) and Department of Interior (DOI) who are working and coordinating on climate
change adaptation and mitigation activities.
III. Vulnerability Assessment
This section contains a preliminary assessment of the vulnerabilities of key EPA New England programs
to the impacts of climate change. It builds on the work presented in Part 2 of EPA's agency-wide Plan,82
and is structured by the goals in EPA's FY 2011-2015 Strategic Plan.83 These vulnerabilities were
identified by the EPA New England Adaptation Planning Workgroup. Note that EPA New England has
not conducted a quantitative vulnerability assessment, but has qualitatively evaluated the nature and
magnitude of risks associated with climate change impacts. This assessment is based on best
professional judgment within EPA at this time and may change in the future as our understanding of
climate science evolves.
23
-------
GOAL 1: Taking Action on Climate Change and Improving Air Quality
A. Overview of Potential Climate Change Impacts
Communities within New England face public health and environmental challenges from ambient and
indoor air pollution. Climate change will increase these challenges. EPA New England partners with
federal, state, tribal and local agencies to protect public health and the environment by directly
implementing programs that address air quality (indoor and outdoor), toxic pollutants, climate change,
energy efficiency, pollution prevention, industrial and mobile source pollution, radon, acid rain,
stratospheric ozone depletion, and radiation protection. Several program areas are vulnerable to future
climate conditions that may be characterized by elevated baseline temperatures, increased frequency and
duration of heat waves, more extreme swings in weather conditions (drought and precipitation events),
and more severe hurricanes and coastal storms. These future conditions will present challenges to EPA
to achieve its core mission.
B. Program-Specific Vulnerabilities
Ozone (Os) and Nitrogen Oxides (NOx)
New England has made progress in attaining the National Ambient Air Quality Standards (NAAQS) for
the current ozone standard of 75 parts per billion, but problem areas remain in southern
New England. 84> 85Although there are continuing NOx and volatile organic compound (VOC) emission
reductions from ongoing control strategies for on-road and non-road mobile sources and fossil-fueled
fired power plants, future climate conditions may make it more difficult to attain the NAAQS for ozone.
Impacts on Os and NOx programs:
• Volatile organic compound emissions from biogenic sources such as trees should increase due to
increased temperatures.86
• NOx emissions from fossil-fuel burning power plants, operating during peak electricity demand
periods, may increase with increased temperatures.87
• The rate of ozone production in the atmosphere should increase with increased temperatures.88
• Additional Os production and inter-regional transport due to prolonged heat waves, stagnation and
increases in upwind emissions.89
• The length of the ozone monitoring season may be extended into early spring and late fall.90
Paniculate Matter (PM)
Similarly, New England has made progress in attaining and maintaining the NAAQS for PIVh.s.
Impacts on PM program:
• There is the potential to see increases in certain air pollutants from power plants (e.g., sulfur
dioxide [SO2], particulate matter less than 2.5 micrometers in diameter [PIVb.s], etc.) during peak
electricity demand due to increased regional temperatures. These increases may contribute to
local air quality problems. 91
• As seen during prolonged power outages from the October 2011 snow storm, PIVh.s violations
from local increases in PM2.5 due to the use of backup electricity (e.g., generators) and heat (e.g.,
wood stoves, fireplaces) sources because of increased extreme weather events and resulting power
outages.
• PM2.5 violations from local increases in PIVh.s may occur due to the uncontrolled burning of storm
debris after intense weather events.
24
-------
Indoor Air
Impacts on indoor air program:
• Extreme weather conditions associated with climate change may lead to breakdowns in building
envelopes, causing the flooding of indoor spaces. Dampness and water intrusion create
conditions favorable to fungi and bacteria (including mold). This can also cause building
materials to decay or corrode, which can lead to off-gassing of chemicals.92
Mercury
Impacts on mercury program:
• Mercury in soils and vegetation, such as boreal peat, may be emitted with increased wildfires
adding to the global atmospheric reservoir. 93Mercury deposition in New England waters and
subsequent mercury contamination offish and wildlife may continue and possibly increase with
the increase in extreme precipitation events.94> 95
• Precipitation events will incorporate a fraction of this global pool in rain and snow, thus
contributing to mercury pollution in the region. Therefore, local and regional efforts to achieve
water quality loading thresholds (Total Maximum Daily Loads, TMDLs) may be more difficult to
achieve.
C. Enforcement and Compliance
Region 1 conducts both Clean Air Act (CAA) enforcement and compliance assistance to the regulated
community on meeting EPA air quality regulations. Increasing resource demands as a result of climate
change impacts could put additional strain on the use of declining resources for these
Enforcement/Compliance activities.
Impacts on enforcement and compliance programs:
• Increased power plant peaking demand could increase the likelihood of emergency generators
being used to meet the peak demand due to increased temperatures and higher mean summer
temperatures.
• There may be an increased burden on compliance and enforcement staff to respond to an
increased number of industry inquiries for regulatory interpretations and CAA applicability
determinations to ensure consistent application of regulatory requirements across the country.
• Major storm or heat events could result in an increased number of requests for temporary waivers
from regulatory requirements, including requirements for gasoline and diesel fuels.
GOAL 2: Protecting America's Waters
Cross-Program Water Man agent en t
While considerable progress has been made since the enactment of the Clean Water Act and the Safe
Drinking Water Act, America's waters continue to be threatened by pollutants including excess nutrient
loadings, stormwater runoff, invasive species and drinking-water contaminants. EPA works with states
and tribes to develop nutrient limits and to restore and protect the quality of the nation's streams, rivers,
lakes, bays, oceans and aquifers. EPA also uses its authority to address urban rivers; to ensure safe
drinking water; and to reduce pollution from nonpoint and industrial dischargers. 96
At EPA New England, protection of regional waters occurs through eleven programs:
1. Water Quality Standards;
2. Monitoring,
25
-------
3. Assessing and Reporting;
4. Total Maximum Daily Loads (TMDLs);
5. National Pollutant Discharge Elimination System (NPDES);
6. Nonpoint Source Management;
7. Wetlands;
8. Dredging/Ocean Dumping;
9. National Estuary Program;
10. Drinking Water, Wastewater, and Stormwater Infrastructure; and
11. Drinking Water Quality.
A. Overview of Potential Climate Change Impacts
In March 2012, EPA published the draft 2072 National Water Program Climate Change Strategy97 which
describes the following impacts to water resources.
• Increases in water pollution due to warmer air and water temperatures and changes in
precipitation patterns, causing an increase in the number of waters categorized as "impaired,"
with associated impacts on human health and aquatic ecosystems.
• Impacts on water infrastructure and aquatic systems due to more extreme weather events,
including heavier precipitation and tropical and inland storms.
• Changes to the availability of drinking water supplies due to increased frequency, severity and
duration of drought, changing patterns of precipitation and snowmelt, increased evaporation, and
aquifer saltwater intrusion, affecting public water supply, agriculture, industry, and energy
production uses.
• Waterbody boundary movement and displacement as rising sea levels alter ocean and
estuarine shorelines and as changes in water flow, precipitation, and evaporation affect the size of
wetlands and lakes.
• Changing aquatic biology due to warmer water and changing flows, resulting in deterioration of
aquatic ecosystem health in some areas.
• Collective impacts on coastal areas resulting from a combination of sea level rise, increased
damage from floods and storms, coastal erosion, salt water intrusion to drinking water supplies,
and increasing temperature and acidification of the oceans.
• Indirect impacts due to unintended consequences of human response to climate change, such as
those resulting from carbon sequestration and other greenhouse gas reduction strategies.
In New England, EPA has identified additional impacts that include:
• Flooding from increasingly frequent and intense rain events as well as intense tropical storms will
tax aging infrastructure, including combined sewer systems, wastewater and drinking water
facilities and adversely impact water quality.
• Dense coastal development and shoreline armoring with sea walls and other hardening structures
will prevent wetland migration and lead to loss of wetlands as the sea level rises.
• Increases in the extent of storm surge and coastal flooding will cause erosion and property
damage to the densely populated coasts.
• Sea level rise may increase saltwater intrusion to coastal freshwater aquifers, resulting in water
resources that are unusable without desalination. Increased evaporation or reduced recharge into
coastal aquifers exacerbates saltwater intrusion.
26
-------
• Sea level rise will lead to direct and indirect losses for the region's energy infrastructure (e.g.,
power plants and located along the coast, marine facilities that receive oil and gas deliveries),
including equipment damage from flooding or erosion. Damaged energy facilities also may be a
source of pollution.
• Aquatic ecosystem species composition and distribution will change due to sea level rise,
increased water temperatures, salinity distribution and ocean circulation, changes in precipitation
and fresh water runoff, and acidification. This will also result in potential for new or increased
prevalence of invasive species.
B. Program-Specific Vulnerabilities
Water Quality Standards
Water Quality Standards are the foundation of the Clean Water Act - they designate the goals and uses
for water bodies, setting criteria to protect those uses, and establishing provisions to protect water bodies
from pollutants. States, territories, and authorized tribes establish water quality standards, and EPA
reviews and approves those standards.
Impacts on Water Quality Standards Program:
• Salinity changes may create a need to reclassify some water bodies from fresh to salt water.
• Recreation and shell fishing season onset and duration may change.
• Some water quality standards may become unattainable due to changing conditions (e.g., warmer
water, drier conditions, less snowpack).
• The relative contribution of snowmelt vs. groundwater flow to stream flow could change,
affecting stream temperature regimes and biological conditions.
• Some designated uses and their associated criteria may need to be removed or changed
based on monitored changes (e.g., intermittent streams may be dry for longer periods of
time in summer and no longer support certain aquatic life forms).
• Some standards (i.e., pollutant-specific goals) may need to change to reflect more
sensitive environmental conditions.
Monitoring, Assessing, and Reporting
Our nation's waters are monitored by state, federal, and local agencies, universities, dischargers, and
volunteers. Water quality data are used to characterize waters, identify trends over time, identify
emerging problems, determine whether pollution control programs are working, help to direct pollution
control efforts to where they are most needed, and respond to emergencies such as floods and spills.
Impacts on Monitoring Program:
• Current location of monitors may no longer be appropriate in order to effectively monitor and
assess changes and to provide access to the monitors (e.g. sea level rise, precipitation,
temperatures, stratification).
• Current detection protocols, criteria, monitoring and analysis may not be sufficient to
detect ocean acidification and/or salinity.
• Current timing of monitoring may not be sufficient in order to pick up seasonal shifts and the full
range of climate vulnerability, especially for recreational and aquatic life uses.
• The current number of monitors used may not be sufficient to assess an increased number of
303(d) impairment listings due to the increased stresses.
• Stream ecosystems will be affected directly, indirectly, and through interactions with other
stressors. Biological responses to these changes include altered community composition,
27
-------
interactions, and functions. Effects will vary regionally and present biomonitoring
challenges for water-quality agencies that assess the status and health of ecosystems.
• With more rapidly changing conditions, more monitoring may be required to adequately
assess the condition of waterbodies.
Total Maximum Daily Loads
Under section 303(d) of the Clean Water Act, states, territories, and authorized tribes are required to
develop lists of impaired waters. These are waters that are too polluted or otherwise degraded to meet the
water quality standards set by states, territories, or authorized tribes. The law requires that these
jurisdictions establish priority rankings for waters on the lists and develop a Total Maximum Daily Load,
or TMDL. A TMDL is a calculation of the maximum amount of a pollutant that a waterbody can receive
and still safely meet water quality standards.
Impacts on TMDL Program:
Over the past decade, EPA Region 1's cross-program effort to address storm water-related water quality
impairments has provided valuable experience in how to develop and implement TMDLs that address
multiple environmental stressors resulting from various flow regimes. For example, impervious surfaces
in urban environments deliver a mix of pollutants and increased flow to rivers and streams resulting in
soil erosion, stream bank scouring, deposition of sediment and nutrients increases in receiving
waters. The increasing amount of impervious surfaces in urban areas causes less precipitation to infiltrate
into the ground, which may cause streams to experience much lower base flows during dry conditions,
along with low dissolved oxygen, increased eutrophication, and higher stream temperatures. Flashy
streamflow conditions (i.e., rapid increases in streamflow and velocity in response to rainfall, followed
by rapid recovery to pre-storm conditions) related to excessive stormwater runoff and corresponding
droughts are anticipated to become even more frequent and/or intense in response to further climate
change.
Stormwater TMDLs now being implemented effectively on a sub-watershed basis involve the use of
surrogates for the mix of pollutants in stormwater (i.e., impervious cover, or flow). Innovative and
flexible approaches to TMDL development like this show promise for addressing the complex challenges
of climate change. For instance, under the surrogate approach, TMDL end-points are tied to aquatic life
use protections in State water quality standards, which provide environmental protection based on
whatever the current conditions happen to be (rather than future projections based on past
conditions). The technical basis for aquatic life use-based TMDLs is derived from significant
investments over the past 35 years developing state ambient biological monitoring programs in our
Region. Bioassessments (using ambient assemblages of macroinvertebrates, fish, or algae that integrate
the effects of multiple stressors over time), in concert with physical and chemical monitoring data, now
support the water quality assessment of aquatic life use attainment for these surrogate TMDLs, and
provide clear environmental indicators of stream health under whatever the existing conditions are.
Summary of anticipated water quality programmatic climate change vulnerabilities includes:
• Challenges in quantitatively demonstrating how implementation of current stormwater BMPs
(occurring primarily through permitting programs), and NFS BMPs, will address future changes
in climate;
• TMDLs may need to be revised in the future as monitoring shows that TMDL target attainment
isn't leading to designated uses being met;
• Increased need for efforts to support local and state partners in additional local land use planning,
stormwater and wastewater TMDL implementation actions needed to achieve the TMDL
endpoints (water quality standards);
28
-------
• Increased need for resources at federal, state, and local levels to address these challenges.
National Pollutant Discharge Elimination System
Water pollution degrades surface waters making them unsafe for existing uses, including drinking water,
fishing, swimming, and other water recreation. As authorized by the Clean Water Act, the National
Pollutant Discharge Elimination System (NPDES) permit program controls water pollution by regulating
point sources that discharge pollutants into waters of the United States. NPDES permits have a five year
permitting cycle.
Impacts on the NPDES program:
• Increased need to respond to requests for assistance from municipalities regarding stormwater
management implementation and financing methods.
• Current thermal discharge limits may not sufficiently account for increasing temperatures of the
influent and receiving waters.
• The assemblage of aquatic organisms residing or transiting a particular receiving water may
change due to water temperature increases.
• Entrainment of different fish species and greater numbers of organisms could occur at power
plant and industrial water intakes due to changes in local communities of organisms as a result of
habitat changes from increased water temperatures and increased cooling water demand.
• Increased extreme precipitation and stormwater runoff will cause an increase in erosion and
sedimentation in receiving waters.
• Reduced flows in streams, especially during summer months, will likely not dilute wastewater
treatment plant and other facility effluents as they do now.
• Water quality standards and BAT/BPT/BCT (Best Available Control Technology Economically
Achievable / Best Practicable Control Technology Currently Available / Best Conventional
Pollutant Control Technology) technology-based limitations may not account for site-specific
effects of:
o changing ambient loading of metals and chemicals from acid deposition, leaching of
contaminated groundwater into discharge infrastructure or movement of pollutants
resulting from flooding, extreme precipitation and atmospheric exchange,
o increasing difficulty of meeting permit requirements due to growing frequency of
extreme precipitation events, storm surge and sea level rise,
o changes in discharge toxicity of specific pollutants (such as ammonia), cumulative effects
of pollutants and persistence of certain pollutants due to changing ambient surface water
and air temperatures.
• A facility's climate change mitigation or adaptation measures may not conform to
BAT/BPT/BCT technology-based limitations.
• More compliance issues in impaired watersheds for NPDES and SOW programs.
Nonpoint Source Management
Nonpoint source pollution comes from many diffuse sources and is caused by rainfall and snowmelt
runoff that picks up natural and human made pollutants and deposits them in lakes, rivers, wetlands,
coastal waters and ground water. State nonpoint source programs, developed under the Clean Water Act
(CWA) Section 319 Program, are working to meet this challenge.
Impacts on the Nonpoint Source Management Program:
• Accounting for greater quantities of runoff and pollutant effluents, with more variability, from
both urban and suburban stormwater and agricultural sources.
29
-------
• Increasing heavy precipitation days and more concentration of runoff in intense storms is likely to
be more damaging to aquatic habitats, and carry more erosion-related pollutants into water bodies.
• Extended drought conditions that may cause inadequate stream flows and further stress aquatic
systems, including the vegetation that is used in riparian areas and in management practices to
filter, treat, and infiltrate effluent flows (e.g. best management practice [BMP] utility may need to
be reevaluated under future conditions).
• More restoration and protection challenges for watershed protection and NFS programs.
Wetlands
Section 404 of the Clean Water Act requires EPA to concur with permits issued by the U.S. Army Corps
of Engineers to allow dredging or filling of wetlands. Wetlands function to protect ecosystems, streams
and other aquatic resources. Wetlands provide four crucial functions for helping to make the Nation
more resilient in response to climate change:
• Coastal protection in the face of sea level rise and increased hurricane intensity, including the
ability to reduce wave energy;
• Protecting Water Supplies in the face of increased drought conditions by providing groundwater
recharge and maintaining minimum stream flows;
• Flood mitigation in the face of increased precipitation and storm frequency in the northeastern
United States. The capacity of wetlands and headwater streams to reduce flood peaks, detain
stormwater, and filter pollutants is critical to the protection of life, property, and water quality;
• Wetlands can serve to sequester carbon.
Impacts on wetlands program (coastal and inland wetlands):
• Wetland migration due to sea level rise that inundate or submerge the wetlands.
• Variability in salinity levels, caused by drought, sea level rise, and increased precipitation and
changes in the plant and animal species that inhabit the wetlands as well as potential impacts on
endangered species and/or critical habitats.
• Increased sedimentation and nutrient loading, with increased precipitation potentially changing
wetland characteristics and structures.
• Drying out of seasonal wetlands with increased drought, which may also potentially change
wetland characteristics.
• Changes in soil dynamics may also affect wetland characteristics, such as hydrology, size, and
sediment types.
• Physical damage or elimination of wetlands and dune structures that protect them due to
hurricanes and other seasonal changes.
• Changes in temperature and rainfall patterns can affect the nature and distribution of inland
wetlands. Decreased precipitation and increased temperatures (greater evaporation and less
frequent flooding), can result in loss of vernal pools and shallow emergent wetland. These
changes can affect the plant and animal species that inhabit the wetlands and may cause potential
impacts on endangered species and/or critical habitats. Sea level rise may submerge/inundate
wetlands, potentially changing wetland characteristics (e.g. designation from fresh to saltwater
wetland).
• Sea level rise and increased storm activity will increase erosion of salt marshes. For coastal
marshes, if sea levels rise at a rate that exceeds the accumulation of substrate (marsh sediments)
the coastal wetlands will break down due to inundation, erosion and intrusion by salt water.
30
-------
Ocean Dumping and Dredging
The Ocean Dumping and Dredged Materials Management programs established by Congress in 1972,
prohibits ocean dumping of materials that would unreasonably degrade or endanger human health or the
marine environment.
Impacts on the Ocean Dumping and Dredging program:
• Increase need and frequency for dredging due to increased precipitation intensity, and severe
storms that may cause erosion and sedimentation of streams, rivers, and harbors.
• Earlier sedimentation due to shorter winters and earlier snowmelts.
• Shifting sediments and forming of shoals in harbors that impede safe navigation and may require
emergency dredging.
• Need for dredged materials to protect shorelines, beaches, dunes and marshes from sea level rise.
National Estuary Program
The National Estuary Program (NEP) was established in 1987 to restore and protect the physical,
chemical, and biological integrity of "estuaries of national significance" by focusing our Clean Water Act
authorities in these highly productive ecosystems. There are 28 NEPs across the country, six of which
are entirely or partially within EPA New England. The NEPs promote technical transfer of information,
expertise, and best management practices to accelerate and embellish implementation of "core" Clean
Water Act programs. Lessons learned by the NEPs are shared across the network of 28 programs
nationally, as well as with other coastal watersheds facing similar water pollution and water quality
impairments. This approach has proven to be a success over the past 25 years and the NEP is seen as a
model for other comprehensive watershed and community-based programs.
Impacts on the NEP Program:
• Biological communities are vulnerable to sea level rise, warming ocean temperatures,
acidification, and increased sedimentation and erosion caused by extreme precipitation events as
well as other impacts described in other water programs above.
Drinking Water, Wastewater, and StormwaterInfrastructure
The Clean Water Act and the Safe Drinking Water Act are the two primary federal laws that protect
water quality and specifically drinking water quality. Both laws include provisions that authorize EPA to
award annual grants to states to help capitalize their State Revolving Fund (SRF) programs, which
support construction and maintenance of wastewater, stormwater, and drinking water treatment and
conveyance infrastructure. The following are some of the most significant threats to water infrastructure
posed by climate change.
Impacts on Drinking Water, Wastewater and Stormwater Infrastructure Programs:
• Damage to infrastructure due to increases in flooding from extreme precipitation, storm surges,
loss of wetlands, and sea level rise.
• Source water intake changes may be needed due to droughts and summertime extreme heat.
• Coastal infrastructure may be impacted by sea level rise.
• Pathogen growth may be fostered due to warmer waters and may test the reliability of drinking
water disinfection.
• Additional pollutant loadings of nutrients, pesticides, and other chemicals may challenge drinking
water treatment.
• Fresh water supplies for all uses, particularly drinking water, may be at risk in coastal areas with
sea level rise.
31
-------
• Coastal aquifers may experience salt water intrusion where withdrawals are outstripping recharge
and increased pressure head from higher sea levels may worsen this problem.
• Community drinking water intakes may end up in brackish waters as the salt front migrates up
coastal rivers and streams.
• There may be an impairment of ability to treat wastewater or provide drinking water in the
aftermath of extreme weather events due to compromised energy infrastructure.
• Decentralized septic systems may be vulnerable to damage from sea level rise, storm surge, and
flooding.
Drinking Water Quality
The Safe Drinking Water Act (SDWA) is the main federal law that ensures the quality of Americans'
drinking water. EPA sets standards for drinking water quality and oversees the states, localities, and
water suppliers who implement those standards.
Impacts on Drinking Water Quality Program:
• Changes in aquifer recharge due to earlier ice breakup causing earlier peak river flows may
require changes in source and demand management.
• Increased runoff and turbidity due to more precipitation falling as rain than as snow.
• Source and demand management changes due to short-term droughts lasting 1-3 months and more
frequent days of extreme heat.
• Threats to source water quality due to flooding, storm surges, coastal flooding, loss of wetlands,
and sea level rise.
• Diminished reliability of future water supply may require water supply management and water
demand management practice changes.
• Changes in the salt front of estuaries and tidal rivers due to sea level rise and fresh water flow
changes may result in increased pressure to manage freshwater reservoirs to increase flows and
attempt to maintain salinity regimes, in order to protect estuarine productivity and drinking water
supplies. Water quality standards in watersheds experiencing reservoir depletion may need to
reflect these conditions.
• Biological expectations may need to be adjusted due to saltwater intrusion.
• May become harder to meet drinking water standards due to higher flows with associated erosion
and sedimentation and lower flows and increased pollutant contamination and reduced dissolved
oxygen.
• Increased contaminants in public drinking water sources and supplies due to runoff from
increased rain events.
C. Enforcement and Compliance
• Extreme weather events can do significant and potentially long-term damage to drinking water
facilities and sewage treatment plants, resulting in contaminated drinking water and the discharge
of untreated sewage in violation of applicable requirements. Such damage will increase the
burden on Enforcement/Compliance programs to respond to these violations and water quality
impairments resulting from such damage.
• It may be physically more difficult to conduct compliance evaluations and inspections in the field
due to harsher weather conditions and extreme weather events. The weather conditions could
have an adverse effect both on the physical well-being of inspectors, as well as on equipment used
32
-------
to monitor and test compliance. Weather conditions and the aftermath of extreme weather events
may affect our ability to actually collect samples and determine compliance.
• Impacts on Enforcement/Compliance resources for enforcement of wetlands regulations could be
particularly impacted by the response to storm surges in vulnerable areas (see wetlands section,
above).
GOAL 3: Cleaning up Communities and Advancing Sustainable
Development
Contaminated site cleanup and waste/petroleum management occur under a variety of EPA programs,
most commonly Superfund (i.e., remedial, time-critical and non-time critical removals, and emergency
response), Resource Conservation and Recovery Act (RCRA), Toxic Substance Control Act (TSCA)
(e.g., polychlorinated biphenyls - PCBs), Clean Air Act (CAA) (e.g., asbestos), and the Oil Pollution Act
(OPA). A high percentage of cleanups, including most Brownfields sites, are regulated through State
programs.
A. Overview of Potential Climate Change Impacts
The potential climate change impacts described below broadly apply to each of the cleanup and
management programs; however, the implications of these climate change impacts may differ by
program.
For New England, the impacts that could most likely pose risks to contaminated sites (including
controlled, uncontrolled, and undiscovered contamination), waste management facilities, and petroleum
storage facilities are sea level rise, extreme storm events (precipitation and wind), temperature extremes,
and decreasing precipitation days and increasing drought intensity. Ocean acidification and increased
water temperatures may also pose additional risks to coastal petroleum storage facilities and affect the
natural bio-degradation of oils released to the environment. Potential environmental conditions arising
from these impacts and specific examples illustrating how they could influence contaminated sites are
described below. The likelihood and severity of climate change impacts can also be expected to vary
considerably from site to site depending on the location, cleanup technologies/approaches used, and
many other factors.
Sea Level Rise: Sea level rise will affect coastal areas in every New England state except for Vermont.
The impact on contaminated sites, waste management facilities, and petroleum storage facilities may be
partially mitigated because sea level rise is expected to occur gradually over the course of decades. This
may allow additional time to appropriately plan for and respond to these changing conditions (e.g.,
construction of berms, removal of wastes, and completion of shorter-term treatment activities).
As a result of sea level rise, contaminated sites, waste management facilities, and petroleum storage
facilities located in vulnerable areas could be subject to inundation and salt water intrusion. Inundation
may lead to the release and dispersal of contaminants, physical damage to remediation-related structures,
degradation of coastal aquifers (thereby impacting cleanup performance goals), and other adverse
impacts. Saltwater intrusion may also impair habitat restoration efforts; cause corrosion of underground
33
-------
tanks, piping, and other equipment; and may lead to changes in soil/water chemical and biological
properties, altering the toxicity, transport, and natural degradation of contaminants.
Extreme Storm Events: Existing climate studies suggest that New England has been experiencing more
intense storm events. Unlike sea level rise, which predominantly affects coastal areas, extreme storm
events can impact a much wider range of contaminated sites. These impacts could include:
• Flooding of surface water bodies and surrounding land areas due to heavy precipitation events
(i.e., regional drainage).
• Flooding of coastal areas and rivers from storm surge due to higher intensity hurricanes.
• Increased local surface runoff.
• Increased infiltration of storm water into soils and elevation of water tables.
• Increased wind damage and dispersion of contaminants.
Because much of the historical development of industry and commerce in New England occurred along
rivers, canals, coasts, and other water bodies, these areas often have a higher density of contaminated
sites, waste management facilities, and petroleum storage facilities. This increases the number of these
sites and facilities potentially vulnerable to flooding. Potential consequences of this flooding include the
spread of contaminants through erosion, dissolving of contaminants, physical entrainment and deposition
of soils or sediments, and flotation and rupture of tanks or drums. Flooding and high winds may also
result in the delay or impairment of remedial operations, and damage to remediation and waste/petroleum
management structures, contaminated buildings, utilities and other related infrastructure. In addition, the
increased amounts of infiltration and runoff, and higher water table levels, could impact the performance
of remediation systems and require management of greater volumes of clean and contaminated ground-
and surface-water. In this way, increased precipitation events and hurricanes may potentially impact sites
even if they are remote from coastal areas and rivers.
In addition, prior to the enactment of environmental laws, industrial wastes were routinely discharged to
rivers/streams, industrial canals, ponds and other water bodies. As a result, many contaminants may exist
within the layers of sediment that accumulated over the years. Increased water flows due to extreme
storm events could potentially re-suspend these sediments, or damage sediment caps, which are
engineered covers intended to prevent contaminated sediments from migrating. Furthermore, river and
canal flooding could also potentially cause the breaching or failure of dams — such as old mill dams
which are numerous in New England — resulting in the spread of contaminated sediment previously
contained by the dams. Such events could also cause flooding impacts to sites or chemical facilities
downstream.
Temperature Change: The direct consequence of elevated temperatures on contaminated site cleanups
is expected to be relatively limited. However, elevated temperatures could lead to increased
pressurization of storage containers, volatilization of hazardous materials, and other factors which may
affect design and operation of remediation systems and emergency response actions. Worker health and
safety concerns during site operations may also be impacted by higher temperatures (e.g., handling of
pressurized drums, heat stress to responders).
Decreasing Precipitation Days/Increasing Drought Intensity: Decreasing precipitation compounded
by higher ambient temperatures may increase drought conditions that could adversely impact the function
of remediation systems (e.g., vegetative layers on landfills, phytoremediation). Droughts also may
increase the potential for wildfires that could further damage remediation systems, and cause contaminant
releases from facilities used to manage hazardous materials and wastes, and from buildings containing
asbestos and other hazardous construction materials.
34
-------
Ocean Acidification: The acidification of sea water may adversely impact the corrosion and degradation
of pipelines and construction materials (e.g. concrete pads/berms) used to convey, store, or contain
petroleum products at coastal facilities.
Increased Water Temperatures: Increased water temperatures may lead to a change in native or
endemic organisms available for biotic degradation of petroleum released to the environment.
B. Program-Specific Vulnerabilities
Longer-term Cleanups (e.g., Superfund Remedial, Superfund Removal, RCRA Corrective Action,
TSCA)
Longer-term response cleanups such as those occurring under the Superfund remedial and removal
programs and the RCRA corrective action program are intended to significantly reduce the dangers
associated with the threats of and actual releases of hazardous substances, pollutants and contaminants
that pose an unacceptable risk to human health and the environment. Many of these cleanups are also
viewed as "permanent" solutions, and thus must be "protective" of human health and the environment.
Impacts on Longer-term Cleanups:
Cleanups where waste is left in place (e.g., landfills, cap-in-place remedies) or involve treatment that
occurs over a long period of time (e.g., ground water pump & treat systems) could be especially
vulnerable to changes in climate. For remedies that are typically of much shorter duration (e.g., soil
vapor extraction, enhanced thermal treatment), the impacts of climate change are more predictable and
easier to factor into the selection and design of a particular remedy. Some specific programmatic
vulnerabilities are:
• Climate change introduces uncertainties into the underlying assumptions that could affect the
selection and design of future remedies (e.g., precipitation records and floodplain maps used for
remedy selection and design may not account for future climate change impacts) potentially
leading to:
o more extensive and costly remedies, such as excavation and removal of wastes, for sites that
are potentially vulnerable to sea level rise and flooding
o designs that are based on conservative engineering assumptions to reflect uncertainty over
future environmental conditions (e.g., planning for increased surface water runoff or
infiltration from extreme storm events)
• There could be physical damage to structures and other components of the site remedy due to
extreme flooding, hurricanes, winter rain/ice storms, and increased drought conditions.
• In some cases, cleanups that were once believed to be protective may no longer meet that standard
as changes in climate occur. This could result in extensive and potentially costly redesign, and
potentially create an extra demand on EPA and State legal and technical resources.
• Sites that were previously not considered or were excluded from cleanup programs may now
require reconsideration under site assessment programs (e.g., changes in the direction and extent
of contaminated ground water; collapse of abandoned, structurally unstable buildings containing
asbestos, lead paint, and other hazardous construction materials).
• The validity of past and ongoing modeling/monitoring could be affected by changing
environmental conditions (e.g., changing groundwater flow, groundwater and surface water
salinity and other chemical properties).
• Assumptions made for the use and value of natural resources may be affected by changes to those
natural resources (e.g., degradation of an aquifer due to salt water intrusion).
35
-------
• Time-critical removal actions, which often bridge the gap between emergency response actions
and longer-term remedial actions, may involve unique challenges resulting from climate change
impacts, such as:
o The preliminary assessment/site investigation (PA/SI) phase of time-critical removal
actions does not currently include potential climate change impacts, and the associated
risk may not be factored into cleanup prioritization.
o The remedy selection process that provides the foundation for more permanent remedies
may not adequately consider climate impacts.
o Time-critical removals often involve labor intensive operations, leading to additional
vulnerabilities from acute impacts of climate change (e.g. flooding and ground water level,
temporary or long-term power outages, extreme heat). These impacts may lead to
increased costs, decreased productivity, and increased migration of contaminants.
o The available capacities for off-site disposal, waste transport, construction equipment, and
laboratory services may be overwhelmed by extreme storm events that may generate large
volumes of hazardous materials and debris (including household hazardous waste). The
intermixing of hazardous materials and debris complicates the separation, collection, and
transport of these materials and also increases disposal costs. Temporary, on-site staging
of hazardous materials and debris may also be adversely affected by flooding and other
conditions that limit usable land space.
o Extreme storm events may create chaotic conditions that increase health and safety risks to
personnel during time-critical removal and emergency response actions (e.g., unstable
buildings/structures; release and intermingling of hazardous materials; physical hazards;
contamination by biological wastes from the flooding of waste water treatment facilities,
sewers).
o Flooding may lead to increased need for dewatering, water treatment and other
remediation processes that can add greatly to the cost of cleaning up the site.
Emergency Response Program
EPA coordinates and implements a wide range of activities to ensure that adequate and timely response
measures are taken in communities affected by hazardous substances and oil releases where state and
local first responder capabilities have been exceeded or where additional support is needed. EPA's
emergency response program responds to chemical, oil, biological and radiological releases and large-
scale national emergencies, including homeland security incidents.
Impacts on Emergency Response Program:
• Releases of hazardous materials or chemicals through high winds, flooding, and storm surge and a
need for increased frequency and intensity of emergency response for both hazardous materials
and oil. Current response resources, including laboratory services, may not be adequate for
responses to extreme events. Specific impacts include:
o The industrial mill infrastructure along New England Rivers poses a unique threat to the
region. Many of these structures contain hazardous chemicals, oil, and contaminated soil
directly adjacent to streams and rivers that may release with extreme storms and flooding
events. Old, structurally unstable mill buildings containing containerized hazardous
substances or hazardous material as part of the structure (e.g., asbestos, lead paint, PCBs) may
collapse due to storm forces and cause releases that could warrant response actions. Potential
for failure of aging mill dams will increase as frequency and intensity of storms stress the
structures, leading to potential impact to chemical and oil facilities downstream.
36
-------
o Increased number of brown/black outs could adversely impact the operation of chemical
facility processes and equipment, leading to potential releases of hazardous materials (e.g.,
runaway reactions).
o Coastal hazardous material and oil facilities may be impacted by extreme storm events (e.g.,
storm surge). The United States Coast Guard (USCG) has jurisdiction over hazardous
material and oil spills along the coast, but the U. S. EPA has interagency agreements in place
to support the USCG during responses.
o Collection of household hazardous waste (HHW) and biological waste collection or mitigation
may be included in EPA's mission during extreme weather events. In preparation for more
frequent events, additional planning may be necessary to plan for response to these wastes
• Pest type and range may change with climate changes and there may be an increase or change in
type of pesticides stored and transported across the region resulting in potential increase in
releases.98
• Additional planning for emergency response may be needed:
o The impacts of increased blackouts/brownouts, severe storm damage, and other adverse
conditions may need to be incorporated into current national and area contingency plans.
o Facility Response Plans (FRP) and Spill Prevention and Control Countermeasures (SPCC)
plans may not adequately consider climate change impacts.
o Current regional debris management plans rely on historical climate assumptions and do not
address the increasing uncertainty in climatic extreme events.
o Additional planning may be needed as Stafford Act declarations (federal emergency
declarations) may be more frequent with a changing climate.
o Current energy infrastructure (oil, natural gas, nuclear) in New England may not include
climate change assumptions for emergency planning.
RCRA Hazardous Waste Management Facilities
The Resource Conservation and Recovery Act (RCRA) regulates, among other things, the treatment,
storage, and disposal of hazardous wastes. Owners/operators of these treatment, storage, and disposal
(TSD) facilities must generally obtain a permit for those activities. Facilities that generate hazardous
waste and store it for 90 days or less are also regulated under RCRA. In New England, the individual
states are authorized to implement this program in lieu of EPA.
In order to operate as a TSD facility, the owner/operator must comply with numerous technical
requirements which ensure that covered activities can be conducted in a manner that is protective of
human health and the environment. These requirements apply to on-going hazardous waste management
units (e.g., drum and tank storage, surface impoundments, waste piles), as well as to the closure (i.e.,
cleaning and decommissioning) of those units that are no longer in use. TSD facilities must also conduct
cleanup of past and present releases of hazardous constituents.
Impacts on RCRA Hazardous Waste Management Facilities:
The same climate change impacts that could affect contaminated site cleanups may also affect the
management and operation of hazardous waste facilities. Some examples are:
• Tanks containing hazardous waste could be damaged by high winds or flying debris during
hurricanes.
• Integrity of drums and drum storage areas could be compromised by flooding, allowing drums to
be floated out of containment barriers, or cause intermingling of incompatible wastes, etc.
• The potential for failure of process equipment (e.g., pressure relief valves, emergency vent fans
and pumps) could increase with increases in winter rain and ice storms.
37
-------
• Over-pressurization of tanks containing volatile wastes and the emergency venting of these
wastes could occur with extreme ambient temperatures.
• Buildings or other structures used for indoor storage of waste piles could be damaged or flooded
in a hurricane causing the release of this material.
• Emergency evacuation routes for facility personnel and the surrounding community, as well as
facility access by fire and other emergency response vehicles, could be flooded or otherwise
restricted due to an extreme storm event.
While the New England states are authorized to implement the RCRA hazardous waste management
program, EPA retains oversight authority to ensure compliance with the statute and regulations and
there may be a need for increased coordination to respond to climate change impacts.
Some specific programmatic vulnerabilities for EPA in its oversight role are:
• Uncertainties in the underlying assumptions that could affect the design, operation and
management of hazardous waste facilities, including contingency planning (e.g., RCRA TSD
facilities must meet specific requirements if waste management units are located within a 100-
year floodplain).
• Financial assurance estimates for closure/post-closure may not reflect changing climate change
impacts on those activities.
Oil Program and Underground Storage Tanks
The Oil Pollution Act (OP A) was signed into law in August 1990. The OP A improved the nation's ability
to prevent and respond to oil spills by establishing provisions that expand the federal government's
ability, and provide the money and resources necessary, to respond to oil spills. To reduce the likelihood
of a spill, regulations issued under CWA Section 31 l(j) (published in the Code of Federal Regulations,
40 CFR Part 112) require facilities that store oil in specified threshold amounts to prepare spill
prevention, control, and countermeasure (SPCC) plans and to adopt certain measures to keep releases
from reaching navigable waters. Certain types of facilities that pose a greater risk of release must also
develop plans to respond promptly to clean up any spills that do occur". It is estimated that there are
between 1,000 and 12,000 SPCC facilities per state and 200 FRP facilities in New England.
EPA created the Office of Underground Storage Tanks to carry out a Congressional mandate to develop
and implement a regulatory program under RCRA for underground storage tank (UST) systems. EPA
works with its state, territorial, and tribal partners to prevent and clean up releases from UST systems.
The greatest potential threat from a leaking UST is contamination of groundwater, the source of drinking
water for nearly half of all Americans. EPA, states, and tribes work together to protect the environment
and human health from potential UST releases. 10°
Impacts on the Oil and Underground Storage Tank Programs:
• Secondary containment and flooding of coastal facilities may be compromised by sea level rise.
• Increase in precipitation and floods may have many impacts, as follows:
o Decrease the effectiveness of secondary containment.
o Increase flow and pressure to underground infrastructure/structures i.e. pipelines,
wastewater treatment facilities, power plants, and paper mills. Increased flow and pressure
to containment systems may result in back feed and flow of product resulting in increased
discharges of oil.
o Decrease tank headspace thereby displacing buffer space available to prevent overflow/
overfill, potentially leading to increased oil spills.
o Increase weathering of underground and aboveground storage tanks (ASTs and USTs).
38
-------
o Increase flow and changes of navigable water depth, thereby increasing difficulty in
preparing and implementing planning distance, booming strategies, and cleanup strategies.
• Failure of infrastructure (e.g. pipelines, and secondary containment) and damage or displacement
of tanks due to increased intensity of hurricanes and resulting winds and storm surges. Damage to
storage tanks would increase the likelihood of spills to navigable waters, coastlines and oceans.
• Increased degradation and weathering of pipelines and infrastructure due to ocean acidification
could result in oil spills.
• Higher ambient temperatures that decrease the viscosity of heavy oil and the lowering of water
tables due to drought conditions may potentially increase the mobilization of oil spills.
• Change in native or endemic organism availability for biotic degradation of oil due to increase in
water temperatures.
C. Enforcement and Compliance
• There may be an increased demand for compliance monitoring support during emergency/disaster
situations (e.g., hurricanes, tornadoes, floods, drought, wildfires), and it may be difficult to deploy
compliance experts in a timely manner to the areas where assistance is needed. Infrastructure
failures may also result in regulatory violations which could require a state or federal enforcement
response.
GOAL 4: Ensuring the Safety of Chemicals and Preventing Pollution
A. Pesticides
EPA receives its authority to regulate pesticide products under the Federal Insecticide, Fungicide, and
Rodenticide Act (FIFRA) registers or licenses pesticide products for sale, distribution, and use in the
United States. As part of pesticide product registration EPA approves, or more properly "accepts"
pesticide label language. In addition, states, usually through a program housed in the State Department
of Agriculture, registers pesticide products available for use in individual states. Anyone planning to
import pesticides into the U.S. must notify EPA.
EPA's Pesticides program covers:
• Providing oversight to state and tribal pesticide programs responsible for certifying and training
pesticide applicators and enforcing pesticide use.
• Implementing the federal certification plan for Pesticide Applicators using Restricted Use
Pesticides in Indian Country.
• Evaluating Potential New Pesticides and Uses.
• Providing for Special Local Needs and Emergency Situations.
• Reviewing Safety of Older Pesticides.
• Registering and inspecting Pesticide Producing Establishments.
• Enforcing Pesticide Requirements.
• Risk assessment.
• Pesticide Field Programs.
39
-------
Impacts on Pesticides Program:
• New pest problems will occur in New England, many of which will be from exotic invasive
species.
• Potential changes in program focus to include more emphasis on structural and public health pests
due to weather related impacts on housing and vector pest habitats (i.e., more standing water)
• Changes in pests and pest pressures due to increases in temperatures and variations in rainfall
patterns.
• Increase in fungal and microbial organisms in agricultural and non-agricultural settings due to
extreme rainfall.
• Changes in chemical and non-chemical agricultural practices due to extreme storms and farmers'
inability to work in their fields (e.g. increases in the likelihood of run-off and off-target movement
of chemical products; limits on the potential use of certain non-chemical methods such as
cultivation because it may not be possible to bring heavy farm equipment onto wet fields and
saturated soils).
• Increased use of aerial applications resulting in increased risk of pesticide drift due to extreme
storm events.
• Increase in dry condition pests due to drought (e.g. mites that feed on a variety of field, vegetable
and fruit crops).
Changes in pesticide choices and quantities may require changes to the pesticide applicator certification
and training programs. Changes in chemical selection could result in new and increased chemical
exposures, especially for indoor applications. Types of new pest problems could include:
• Indoor and outdoor molds and microorganisms which are controlled by disinfectant pesticide
products;
• Public health pests such as mosquitoes and ticks;
• Forest pests,
• Aquatic pests including weeds; and
• Various agricultural pests including weeds, insects and plant diseases.
B. Enforcement, Compliance and Pollution Prevention
Enforcement
As with other regulatory programs, climate impacts noted above could cause an increased strain on
Enforcement/Compliance resources because of an increased need to respond to changes in pesticide
choices and application methods.
Pollution Prevention
The long term response to climate change may create demands on EPA and state pollution prevention
programs due to the need to provide additional assistance to the regulated community. As an example,
there may be increased demand for assistance regarding mitigation methods for reducing GHG
emissions. Green Chemistry resources will be in greater demand as businesses and the public seek more
sustainable substitutes for materials used for manufacturing and other industrial and commercial
activities.
Facilities and Operations
Climate change poses a range of risks to EPA New England's facilities and operations. The following
sections detail the general risks and then delve into the risks specific to each facility. Note that each
40
-------
facility does not operate in isolation; the climate impacts experienced by each facility will be greatly
influenced by the larger systems (utilities, transportation, communities) of which it is a part.
A. Overview of Potential Climate Change Impacts101
From the facilities and operations perspective, the vulnerabilities associated with climate change
encompass issues of energy security, water quality and supply, severe weather and flooding damage,
personnel safety, physical security, and communications interruptions. Facilities and operations support
the broader agency mission of protecting air, water, and human health through the provision of
functional, appropriate, and safe working spaces for personnel. Beyond the infrastructure and utilities
that serve EPA rented or owned facilities and the operations that support the function of those facilities,
broader impacts of climate change on transportation and communication systems are also vulnerabilities
that can hamper EPA New England's efforts to meet agency goals. While telework policies are in place
to address these vulnerabilities, the magnitude of these impacts may extend to those alternate work
locations, causing significant disruption to employee work and ultimately hampering fulfillment of the
EPA New England mission.
However, while operations may be vulnerable in the areas described above, EPA New England has
developed a Continuity of Operations Plan (COOP) to maintain emergency functions should any
particular facility or location be compromised. This plan provides guidance for continued uninterrupted
operations and the performance of essential functions during emergency situations. The COOP includes
provisions for physical relocation from current facilities and resource planning for up to 30 days.
B. Facility-Specific Vulnerabilities
The Boston McCormack office building located in Boston, MA is approximately 0.5 miles from the
Boston waterfront and sits at an elevation of approximately 12.3 feet (2.76 meters) above mean sea
level.102 The building is a massive granite structure, serviced by underground utilities for water, natural
gas and steam heating. All building mechanical systems are on the 17th floor roof. Most notable about
this facility is its position as a part of a larger urban community. While impacts can be explored with the
view that the building sits in isolation from the rest of the city, more likely, the experience of impacts will
be moderated and influenced by its proximity to other buildings and infrastructure of significance.
The impacts and risks associated with higher water levels from sea level rise, storm surge or flooding
include: building damage, inaccessibility of the building to employees, and damage to the larger utility
systems that support the operation of the McCormack building. In addition, mobile equipment (e.g.
vehicles, emergency response resources, etc.) stored in the building's basement may be vulnerable to
flooding. However, the structural soundness of the building will limit the impacts of extreme weather on
the building itself, and the location of mechanical systems on the 17th floor will limit the damage to
critical building equipment. In addition, the McCormack building is equipped with a natural gas fueled
backup generator.
The Boston office utilizes a parking garage for Government Owned Vehicles. The vehicles are on the
ninth floor of the parking structure and are not susceptible to flooding concerns because of the high
elevation. However, access to this facility may be hampered by local flooding, affecting the usability of
those vehicles.
41
-------
The Chelmsford Lab is built high on a hill approximately 40 miles from Boston Harbor, at an elevation of
156.2 feet (47.61 meters) above mean sea level103 obviating any risks of sea level rise or direct flooding.
However, surrounding roads may be flooded during extreme storms.
The power grid near the Chelmsford Lab is particularly susceptible to several hour power interruptions
due to rain and wind. Due to the existing weaknesses of the power grid, the Lab is equipped to manage
short interruptions. At this facility, oil fueled backup generators have been sufficient for up to 44 hours
of backup power and can be extended by additional fuel deliveries.
EPA's Emergency Response Warehouse is located approximately 30 miles from Boston Harbor at the
intersection of Routes 128 and 1-93 in an industrial park. At an elevation of 73.3 feet (22.36 meters)
above mean sea level,104 the likelihood of sea level rise impacts is very low. Impacts to the larger
transportation systems may affect accessibility, but similar to the McCormack building, those impacts are
a part of the larger context and beyond EPA's control and jurisdiction. The susceptibility of this facility
and its access roads to flooding due to nearby rivers and water bodies is currently unknown. Impacts to
this warehouse may affect the access to and availability of emergency response resources that are stored
at this location.
Tribal and Vulnerable Populations
The impacts of climate change may disproportionately impact tribal communities and vulnerable
populations, including children.
Tribal Communities
EPA values its unique government-to-government relationship with Indian tribes in planning and
decision making. This trust responsibility has been established over time and is further expressed in the
1984 EPA Policy for the Administration of Environmental Programs on Indian Reservations and the
2011 Policy on Consultation and Coordination with Indian Tribes. These policies recognize and support
the sovereign decision-making authority of tribal governments.
Supporting the development of adaptive capacity among tribes is a priority for the EPA. Tribes are
particularly vulnerable to the impacts of climate change due to the integral nature of the environment
within their traditional lifeways and culture. There is a strong need to develop adaptation strategies that
promote sustainability and reduce the impact of climate change on Indian tribes.
EPA engaged tribes through a formal consultation process in the development of the Agency's Climate
Change Adaptation Plan. Tribes identified some of the most pressing issues as erosion, temperature
change, drought and various changes in access to and quality of water. Tribes recommended a number of
tools and strategies to address these issues, including improving access to data and information;
supporting baseline research to better track the effects of climate change; developing community-level
education and awareness materials; and providing financial and technical support. At the same time,
tribes challenged EPA to coordinate climate change activities among federal agencies so that resources
are better leveraged and administrative burdens are reduced.
This Implementation Plan identifies specific steps that will be taken to partner with tribal governments on
an ongoing basis to increase their adaptive capacity and address their adaptation-related priorities. These
collaborative efforts will benefit from the expertise provide by our tribal partners and the Traditional
Ecological Knowledge (TEK) they possess. TEK is a valuable body of knowledge in assessing the
42
-------
current and future impacts of climate change and has been used by tribes for millennia as a valuable tool
to adapt to changing surroundings. Consistent with the principles in the 1984 Indian Policy, TEK is
viewed as a complementary resource that can inform planning and decision-making.
Networks and partnerships already in place will be used to assist tribes with climate change issues,
including the National Tribal Operations Committee, Regional Tribal Operations Committees, the EPA-
Tribal Science Council, the Institute for Tribal Environmental Professionals and the Indian General
Assistance Program (IGAP). Additionally, efforts will be made to coordinate with other Regional and
Program Offices in EPA, since climate change has many impacts that transcend media and regional
boundaries. Transparency and information sharing will be a focus, in order to leverage activities already
taking place within EPA Offices and tribal governments.
There are 10 federally recognized tribes (see Figure 7 105) in New England and climate change may have
the potential to disproportionately impact tribal communities compared to non-tribal communities.

Environmental Justice
The impacts of climate change raise environmental justice issues. Environmental justice focuses on the
health of and environmental conditions affecting minority, low-income, and indigenous populations.
EPA places emphasis on these populations because they have historically been exposed to a combination
of physical, chemical, biological, social, and cultural factors that have imposed greater environmental
burdens on them than those imposed on the general population. Climate change is likely to exacerbate
existing and introduce new environmental burdens and associated health impacts in communities dealing
with environmental justice challenges across the nation.106
44
-------
Children
The impacts of climate change can have unique effects on the health of children. Children are different
from adults in how they interact with their environment and how their health may be affected.
Below is a list of potential impacts on tribal populations, environmental justice communities, and
children, broadly organized by EPA programs.
A. Air
Impacts on tribal programs (raised by tribal leaders and tribal environmental departments at various
meetings with the Agency):
• Potentially higher health risk of methyl mercury contamination due to higher fish and shellfish
consumption by tribal members compared to the average consumer.107
• Potentially higher risk of exposure to increase in mercury and cadmium as well as other pollutants
as it concentrates in moose liver, turtle, and fiddlehead ferns consumed by the Maine tribal
populations. 108>109
• Potentially higher mercury exposure from tribal members' reliance on wood stoves for home
heating, and increased air transport and deposition of mercury or other contaminants that
bioaccumulate on wood bark. no
• Higher incidence of asthma as indoor air exposure to mold and second-hand smoke exposure
increases with more time spent indoors due to more extreme weather events.
• Impacts to sustenance practices due to warmer ambient temperatures and extended warmer
seasons as predator tick populations impact moose and deer hunting111, invasive plant species
impact agronomic practices such as fiddlehead harvesting and blueberry farming, and invasive
insects such as the emerald ash borer impact native practices involving black ash species (e.g.
basket-making for harvesting).112
• Moose populations may decline due to warmer mean temperatures in winter.113
• Forestry operations and changes of species from hardwoods such as oak and maple to more
spruce and fir populations with temperature increase.
Impacts on vulnerable populations:
• Combination of heat stress and high concentrations of tropospheric ozone could pose a health risk
to young children, the elderly, and those with pre-existing health conditions, including
asthma. 114Increase in health risks from worsening indoor environmental conditions due to
increases in mold and other indoor air pollutants as a result of increased flooding or leaks from
storm events.115
• Increase risk to low-income households from extreme heat events due to lack of air conditioning
or failure to use air-conditioning to cut down on associated energy costs.116
Impacts on children:
• Increased frequencies of elevated levels of ozone may lead to a number of adverse health effects
in children, such as shortness of breath, chest pain when inhaling deeply, wheezing and coughing,
temporary decreases in lung function, and lower respiratory tract infections.117' 118
• Increased levels of particle pollution during extreme weather events could cause increased
exposure to children. Childhood exposure to paniculate matter has been associated with
respiratory symptoms, decreased lung function, development of chronic bronchitis, and worsening
45
-------
of asthma. Children's exposure to particle pollution can result in increased hospital admissions,
emergency room visits, absences from school and restricted activity days.
• If radon is present in schools, higher incidence of exposure to radon with more time spent indoors
due to more extreme weather events.
B. Water
Impacts on tribal programs:
• Coastal infrastructure may be impacted by sea level rise including the Passamaquoddy Pleasant
Point wastewater treatment facility that is located near sea level with an ocean outfall discharge.
• Ocean acidification may have a particularly acute impact on the coastal tribal members, including
Passamaquoddy, Mashpee Wampanoag and the Wampanoag Tribe of Gay Head (Aquinnah) who
depend on shellfish harvesting for sustenance practices, employment and economic development.
• Lobster shell wasting disease that may be linked to climate change has also been raised as a
concern.119
• Damage to wildlife and fish habitat, potentially altering spawning habitat by increasing siltation
due to sea level rise.
• Cold water fish species such as trout and salmon may be more susceptible to poisons, parasites
and disease, and stunted fish growth, as well as increased juvenile mortality resulting from lower
oxygen levels due to warmer waters.
• Fishery habitat including nesting sites and increased fish mortality due to flooding of tribal rivers
as a result of increased snowfall and rapid snowmelt. Tribal communities depend on sustenance
fishing.
Impacts on vulnerable populations:
• Increase in severity and frequency of extreme storms can result in catastrophic effects for coastal
environmental justice communities with limited resources to prepare and respond to natural
disasters.
• Increase risk of exposure to hazardous substances as flooding from more intense and frequent
storms and sea-level rise may lead to contaminant releases from Corrective Action sites,
Superfund sites, Brownfield sites and landfills which often are located in close proximity to
environmental justice communities.
• Impacts to water infrastructure may put vulnerable and economically deprived communities at
risk, both for access to clean and safe water as well as for their ability to respond to emergencies
during extreme events.
Impacts on children:
• Extreme weather also can result in the breakdown of sanitation and sewer systems, increasing the
likelihood of water-borne illness. Children are especially susceptible to such illness due to their
developing immune systems.
• School drinking water supplies may be compromised. New England schools are responsible for
providing safe drinking water to their students, staff and visitors. Many school systems do not
have access to a nearby public water supplier and provide drinking water by operating their own
onsite well water system.
• Increases in the extent of storm surge and coastal flooding will cause erosion and property
damage to schools along the densely populated coasts.
46
-------
C. Waste and Pesticides
No tribal impacts were identified that would be different from the impacts of the surrounding community
for these programs.
Impacts on vulnerable populations:
• Potential changes in pesticide exposures may exacerbate existing burdens placed on children,
agricultural workers and other groups who may be disproportionally affected.
Impacts on Children:
• Schools may experience a higher incidence of exposure to chemicals and pesticides increases with
more time spent indoors due to more extreme weather events.
Cross-Cutting Vulnerabilities
A. Energy
Managing electricity and natural gas facilities to meet environmental goals and reliability standards will
be challenged by long term temperature increases and increased extreme weather events.
Temperature increases will increase energy demand, particularly on peak summer days. As demand
increases, additions and adjustments to the electric generating system need to be made. Many of the
typical responses to these increases may increase air pollution emissions.
Additionally, since thermal power plants operate at lower capacities in the summer versus the winter, the
higher ambient temperatures get, the less efficient the power plants are over a greater portion of the year,
resulting in the consumption of more fuel, thus more emissions, to produce an equivalent amount of
usable energy. In addition, higher cooling water temperatures during summer months also mean that the
power plant will operate at less than its peak capacity. As a result, as long-term temperatures increase,
the overall efficiency of most power plants will decrease, resulting in higher emissions per megawatt-
hour produced over a larger portion of the year. This situation will not be unique to New England, and
New England will also be adversely impacted by additional pollution moving into the region as a result
of similar situations in upwind states and control areas.
The increased frequency of extreme weather events will impact the integrity of the energy system and can
lead to the disruption of electrical service. During the cold weather season, residents without power are
forced to utilize alternative methods of heating such as wood stoves or fireplaces. The resulting increase
in wood burning can contribute to elevated ambient fine particle (PM2.s) pollution concentrations. This
phenomenon was observed in the several days of "unhealthy for sensitive groups" (USG) PM2.5
concentration measured in the Springfield, MA area following the October 29, 2011 snowstorm.120
Power losses usually result in the increased usage of local generators which produce much more pollution
per unit of usable energy than a typical power plant. In addition, since both drinking and waste water
require substantial amounts of energy, long term disruptions in energy infrastructure can result in
negative public health outcomes related to an inability to provide clean water or treat wastewater.
Restoration of such capabilities within acceptable environmental parameters should be a priority for
emergency response restoration efforts as well.
47
-------
Sea level rise will also lead to direct and indirect losses for the region's energy infrastructure (e.g., power
plants located along the coast, marine facilities that receive oil and gas deliveries), including equipment
damage from flooding or erosion.
Air Issues/Impacts:
• Increased atmospheric concentrations of criteria pollutants due to increased electric demand
resulting from heat waves and generally higher temperatures. New England will be impacted
from inter-regional transport of pollutants caused by similar situations in upwind states.121
• Increased levels of criteria pollutants may result from decreased capacities of electric generating
units to operate due increased temperatures of cooling water. Long term temperature increases
may require a proportionally higher number of electric generating units (EGUs) to provide
equivalent amounts of power.
Water Issues/Impacts
• Decreased power output from power plants resulting from increases in the waterbody
temperatures that supply cooling water to the plant.
• The Region may be requested to allow enforcement forbearance to allow the discharge of heated
water into water bodies that exceed the temperature limits in violation of the power plant's
NPDES permit, in order to permit electrical generation.
• Impairment or inability to treat wastewater or provide drinking water in the aftermath of extreme
weather events.
B. Communications
Effective communication to stakeholders is critical to meeting EPA's mission. The following are impacts
on communications at EPA New England.
• As communities are impacted by severe storms, impaired waters, contaminated flood waters, and
other impacts of climate change, current communication mechanisms regarding the environment
and public health during these periods may not be sufficient to ensure that communities receive
the appropriate guidance on how to react to these events and protect public health.
• Current mechanisms of communications with states, cities and towns, and guidance regarding
how to best handle climate change impacts and vulnerabilities may not be sufficient.
• Current mechanisms regarding how EPA communicates information may not be sufficiently easy
to access and understandable to the audience in need, both during emergency events and when
conducting communication on climate change impacts.
48
-------
IV. Priority Actions
The EPA New England climate change programmatic vulnerability assessment points to the specific
program and operations that may be impacted by the projected climate changes. Based on these
vulnerabilities, EPA New England identified priority actions it could take to ensure that we can continue
to accomplish our mission and operate at our multiple locations. These priorities represent EPA New
England's commitment to address the known programmatic vulnerabilities, and to continue to identify
other vulnerabilities that may occur over time due to climate change.
The workgroup developed a set of criteria to take into consideration when evaluating the priority actions.
The following qualitative criteria were considered. .
• Timeframe when risk would occur?
• Magnitude of impact of risk on environment or health?
• Magnitude of impact on EPA program?
• Does the action reduce the risk?
• Does the action protect a critical resource/investment?
• Does the action address "low-hanging fruit" that would be easy to accomplish?
• Would the action leverage a larger effort outside of EPA?
• Does EPA have a unique role or capacity to address this issue?
• What is the timeframe of the problem that this action would be addressing?
Could the action be accomplished within current budgets or would additional funds be necessary?
Taking these criteria into account, priority actions were determined for each strategic goal. The
following section summarizes the priority actions for each goal.
GOAL1
Ozone and NOx
1. Work with other EPA Regions and HQ air program managers to develop a strategy, in context to
other programmatic priorities, on how to incorporate climate adaptation into air quality programs
(e.g., SIPs, permits).
2. Develop new VOC and NOx control strategies with the States to offset the effects from higher
peak (and prolonged) temperatures as necessary.
PM
3. Devote more Regional staff time to providing the public with "Burn Wise" information, and work
with the states and tribes to inform the public about unhealthy air quality.
4. Work with the States to analyze further control strategies for wood combustion to avoid PM2.5
violations.
Indoor Air
5. Prepare information and recommendations regarding mold and other indoor air quality issues for
distribution to the public due to increase in extreme events and flooding, and residents spending
more time indoors.
6. Enhance messaging on the dangers from backup electricity sources (e.g. generators) and heat
sources (e.g., wood stoves, fireplaces) that might be used more frequently due to power outages.
7. Devote more Regional staff time as needed to answer indoor air calls from the public.
49
-------
Enforcement
8. Enhance Regional compliance assistance efforts to insure emergency generators are properly
used, and are in compliance with applicable state and federal requirements.
9. Enhance Regional compliance monitoring efforts to insure that air pollution sources are properly
controlled and in compliance with applicable state and federal requirements.
Tribal Programs
10. Work with New England tribes to monitor and assess local mercury deposition trends and advise
them on potential additional health precautions to take, if and when trends indicate increases in
atmospheric deposition and corresponding increasing mercury levels in fish and turtle.
GOAL 2
Water Quality Standards
1. As circumstances arise, revise water quality criteria to reflect climate change impacts.
2. As conditions change, modify water body classifications (salt v. fresh water) or Integrated Report
designations (e.g., causes of impairment) to reflect climate change impacts.
Monitoring, Assessment, and Listing
3. Increase monitoring to adequately assess the effects of rapidly changing conditions.
4. Continue to support EPA's National Aquatic Resource Surveys (NARS), which provide ongoing
assessment of the ecological condition of statistically representative samples of wadeable streams,
large rivers, wetlands and coastal resources.
5. Implement collaborative year-round monitoring of high-quality (reference) wadeable streams,
with other water resources to follow as feasible, for temperature, flow, physical habitat, biological
resources, and other water quality parameters such as nutrients, as proposed in the state, tribal and
federal Northeast (New England and NY) stream climate change monitoring network.
6. Work with HQs to develop and implement a national monitoring program for ocean acidification
(OA), which is caused by the dissolution and reaction of carbon dioxide (CO2) into ocean water.
7. Modify freshwater, estuarine, and marine sampling protocols and locations based on effects of
climate change, including sea level rise, considering the need for a long term monitoring record.
Total Maximum Daily Load (TMDL)
Over the past decade, EPA Region 1's cross-program effort to address storm water-related water quality
impairments has provided valuable experience in how to develop and implement TMDLs that address
multiple environmental stressors resulting from various flow regimes. For example, impervious surfaces
in urban environments deliver a mix of pollutants and increased flow to rivers and streams resulting in
soil erosion, stream bank scouring, deposition of sediment and nutrients increases in receiving
waters. The increasing amount of impervious surfaces in urban areas causes less precipitation to infiltrate
into the ground, which may cause streams to experience much lower base flows during dry conditions,
along with low dissolved oxygen, increased eutrophication, and higher stream temperatures. Flashy
streamflow conditions (i.e., rapid increases in streamflow and velocity in response to rainfall, followed
by rapid recovery to pre-storm conditions) related to excessive stormwater runoff and corresponding
droughts are anticipated to become even more frequent and/or intense in response to further climate
change.
50
-------
Stormwater TMDLs now being implemented effectively on a sub-watershed basis involve the use of
surrogates for the mix of pollutants in stormwater (i.e., impervious cover, or flow). Innovative and
flexible approaches to TMDL development like this show promise for addressing the complex challenges
of climate change. For instance, under the surrogate approach, TMDL end-points are tied to aquatic life
use protections in State water quality standards, which provide environmental protection based on
whatever the current conditions happen to be (rather than future projections based on past
conditions). The technical basis for aquatic life use-based TMDLs is derived from significant
investments over the past 35 years developing state ambient biological monitoring programs in our
Region. Bioassessments (using ambient assemblages of macroinvertebrates, fish, or algae that integrate
the effects of multiple stressors over time), in concert with physical and chemical monitoring data, now
support the water quality assessment of aquatic life use attainment for these surrogate TMDLs, and
provide clear environmental indicators of stream health under whatever the existing conditions are.
8. Promote use of hydrological information to the extent available and adequate that takes climate
change effects into consideration during development of TMDLs, their implementation plans,
NFS plans, and NPDES permits.
9. Support increased monitoring to assess the effectiveness of attained TMDL targets in the face of
changing conditions.
10. Promote close collaboration among TMDL, NPDES, and NPS program staff during stormwater
TMDL development and public outreach, in order to help MS4s and other stakeholders
understand the need for more detailed local watershed planning for stream restoration actions and
the use of structural and non-structural BMPs as part of post-TMDL implementation.
To address new information and evolving circumstances, focus climate change adaptation on the
selection and design of more effective TMDL implementation. For example:
• Promote selection of BMP types that perform well under varying climate conditions, such as
certain low impact development practices.
• Promote consideration of projected precipitation changes during the design of stormwater
BMPs and other practices built to accommodate or treat specific storm sizes or runoff
volumes, especially when these investments are anticipated to have life expectancies of 30
years of more.
• Support BMP studies to evaluate how resilient BMPs are to climate change, and whether
additional capacity is warranted to address future concerns, such as flooding or groundwater
recharge.
Cross-Program Water Management
In line with EPA's agency-wide climate change priorities and strategic measures, Region 1 priority
actions will continue to focus on cross-program stormwater management, and will continue interagency
collaboration and development of decision-making tools capable of promoting environmentally sound
and cost-effective management actions. For example:
11. 2010 RARE-funded project, Assessing Effectiveness of Green Infrastructure Stormwater BMPs at
the Small Watershed Scale (WQ Branch & ORD/Narragansett).
12. 2011 ORD Green Infrastructure-funded project, Development of an Integrated Watershed
Management Optimization Decision Support Tool, which accounts for water supply, wastewater,
stormwater, in-stream conditions, groundwater, and land use to achieve optimal actions to achieve
water quantity-related management goals at least cost (collaboration among WQ and SOW
programs).
13. Major regional meetings in 2012 and 2013 were co-sponsored with USFWS and USGS on
temperature data and monitoring which has prompted NE CSC research projects on climate
51
-------
change impact on headwater systems (areas of aquatic refugia), and development of a multi-
agency regional stream temperature framework and database for New England (ME, NH, CT, RI,
and MA) and the Great Lakes States (MN, WI, IL, MI, IN, OH, PA, NY).
14. , Develop Optimizing Stormwater/NutrientManagement Region 1 Opti-Tool, a user-friendly
(spreadsheet) tool allowing optimization of structural and non-structural BMPs, and account for
BMP pollutant removal, stormwater flow control performance, and estimated cost (collaboration
among TMDL and NPDES programs).
15. Estimate how stormwater controls would work cumulatively to address future changes to
precipitation patterns in order to determine whether or not modification of the levels of control is
warranted.
National Pollutant Discharge Elimination System (NPDES) Permits
16. Review water treatment requirements as reduced water flows in streams, especially during
summer months, will not dilute treatment plant effluents as they do now, so more treatment may
be needed to maintain current water quality standards.
17. Stormwater permits will need to account for increased extreme precipitation and erosion and
sedimentation.
18. Promote the "Soak up the Rain" program.
19. Permits with temperature limits (e.g., electric generating units) will need to account for increased
water temperatures in receiving waters and potential changes to local assemblages of aquatic
organisms.

as well as the potential use of thin layer dredged material disposal in eroding coastal wetlands.
28. Review and comment on Corps permit applications for coastal engineering structures to evaluate
potential adverse impact on coastal wetlands, considering sea level rise and marsh migration
potential.
29. Recommend consideration of "living shorelines" where appropriate to restore eroding wetlands
and protect shorelines as an alternative to hard engineering structures.
30. Prioritize restoration work for tidal wetlands that have room to migrate.

associated with more extreme precipitation.
52
-------
34. Promote Regional Sediment Management approaches to better understand sediment dynamics and
potentially reduce the need for, or frequency of, dredging.
35. Modify dredging windows to better align with changes in seasonality (earlier fish migration and
spawning).

vulnerability assessments, prepare adaptation plans, and develop tools to facilitate these activities,
like the Connecticut Adaptation Resources Toolkit.
37. Promote the New England Environmental Finance Center's use of the Coastal Adaptation to Sea
Level Rise Tool (COAST) to raise awareness among coastal cities and towns about the economic
impact of sea level rise and storm surge on coastal property and infrastructure.
38. Develop guidance for different coastal habitat types (dunes, dams, etc.) restoration activities to
account for sea level rise.
39. Revise and update Comprehensive Conservation and Management Plans (CCMPs) to address
vulnerabilities to climate change and include adaptation measures.

41. Promote implementation of more effective erosion and sediment controls to adapt to increasing
heavy precipitation events and storm intensity.
42. Support efforts to better characterize impacts of ocean and coastal acidification in cooperation
with the Northeast Coastal Acidification Network (NEC AN).
Drinking Water, Wastewater, Stormwater Infrastructure
43. Educate and encourage use of Water and Wastewater Agency Response Networks (WARNs) to
promote specialized water sector mutual aid and recovery in events of infrastructure damage or
other emergencies.
44. Through the Climate Ready Water Utilities program, educate facility operators on using localized
climate projections to help identify specific vulnerabilities, including Geographic Information
Systems (GIS) and Light Detection and Ranging (LiDAR) mapping of flood zones. Facilities
should then update and train staff on revised Emergency Response Plans as needed.
45. Promote the WaterSense program to help utilities implement water efficiency/conservation
measures to reduce or delay the need for system expansion and reduce energy use.
46. Encourage utilities to compile an inventory of utility assets to help determine the location,
importance and condition of each asset, which will lead to an improved response in emergency
situations. Provide assistance to municipalities and others on use of asset management methods.
47. Promote green infrastructure projects, such as low impact development (LID), to help manage wet
weather and improve water quality, reduce hydraulic loads on combined sewers, and reduce the
risk of flooding. Increase public understanding of the need to implement and finance Stormwater
management systems.
48. Develop outreach and tools for flood proofing infrastructure.
49. Promote opportunities such as periodic larger-scale system evaluations, planned upgrades, or new
construction to incorporate climate-change considerations into facility design. Educate utilities on

improvements.
50. To help ensure that climate change impacts on septic systems are addressed in a proactive
manner, assess which areas in New England may be vulnerable to damage to decentralized septic
systems due to sea level rise, storm surge, and flooding, starting with Cape Cod. Based on the
results of the mapping assessment, determine appropriate actions, including promoting improved
53
-------
decentralized sewage system management in accordance with EPA's Voluntary Guidelines.

V. Measurement and Evaluation
This section describes how EPA New England will incorporate priority actions into its programs and how
these actions will be measured.
A. Measure: Integrate climate adaptation priority actions into the GCCN strategy annually and into other
planning documents as needed.
Evaluation: Include consideration of climate impacts into at least 3 processes (e.g., permitting, grant
solicitation, enforcement integrated strategies, Invasive Species Control Plans) in the GCCN FY 14 plan.
Annually thereafter, review the vulnerabilities and priority actions to update according to the current
science and actions taken by others to determine what to address in the annual GCCN Strategy.
B. Measure: Work with states and tribes to integrate climate adaptation into State-EPA and Tribal-EPA
planning mechanisms (e.g. PPA/PPGs, begin preliminary discussion in FY 14). Work with grantees and
local communities to integrate climate adaptation into planning mechanisms.
Evaluation: All NE states and at least some of the tribes will incorporate adaptation into at least one
program action and planning mechanism. Grantees and local communities incorporate adaptation into
their planning.
C. Measure: EPA New England will work with EPA national Program offices on national program
climate adaptation guidance (e.g., oil program, streamlining of FIFRA registration process, dredging)
Evaluation: Participation in workgroups as invited.
D. Measure: Improve preparedness for extreme events, including incorporating climate change impacts
(e.g., flooding, storm surge) into planning documents (e.g. Emergency Planning documents) and outreach
(e.g., guidance use of back-up power and alternative heating sources).
Evaluation: EPA will develop response protocols and tools for public outreach; Dialogue with Region 2
to learn from Super Storm Sandy experience.
E. Measure: Collaborate with other federal agencies, academics and NGOs in New England regarding
climate change impacts (e.g. coordinating with NEFP, NROC, etc.)
Evaluation: Identify and act on collaboration opportunities to increase scientific understanding and to
increase resiliency.
F. Measure: Train EPA employees and states and tribes where appropriate on how to consider impacts of
climate change in their EPA duties and obligations.
Evaluation: 90% participation in climate adaptation training.
G. Measure: Conduct outreach on climate change impacts to affected stakeholders (E.g., Soak Up The
Rain, outreach to vulnerable population, Burn Wise)
Evaluation: Development of outreach tools and outreach campaigns or events.
