Shanika Whitehurst

Mr. John Shoaff (EPA) explained that the purpose of the meeting was to facilitate a "meet and
greet" with the new leadership team at the Office of Air and Radiation (OAR) and would include
time for questions and public comment.

Introduction of Speakers/Discussion

Mr. Shoaff invited each of the new appointees to introduce themselves.

Mr. Tomas Carbonell, the new Deputy Assistant Administrator for Stationary Sources, began by
emphasizing that as a former member of CAAAC, he appreciates the perspectives and expertise
that members bring to the table, and he is looking forward to hearing from everyone and working
together. He described his background studying science and engineering at North Carolina State
University, then transitioning into environmental law through an internship in Washington, D.C.
and later at law school. In his career at the Environmental Defense Fund, he worked with a broad
array of partners and stakeholders on rulemaking and litigation. He added that he is humbled and
inspired to work in public service and be part of the Biden Administration's efforts to prioritize

1


-------
climate change, environmental health, and environmental justice while following the law and
staying grounded in science.

Ms. Alejandra Nunez, the new Deputy Assistant Administrator for Mobile Sources, reiterated the
sentiment that CAAAC members have provided valuable input to EPA in the past, and she is
looking forward to receiving the recommendations in the 50th anniversary report being prepared.
She explained that the OAR leadership team is still in a transitional phase, but they are looking
forward to beginning to implement the Biden Administration's agenda. She described her
background working at the Sierra Club on advocacy related to climate change regulations as well
as her experience in transportation, including vehicle standards. Previously, she worked on
public-private partnerships at the World Bank and was an associate at a law firm. Her priorities
include air quality, public health, climate change, and environmental justice, and she is looking
forward to hearing the perspectives of CAAAC members as well as EPA's expert staff on how to
best accomplish President Biden's environmental goals.

Ms. Eunjung Kim, special assistant to OAR, described her background in engineering and
experience with the Army Corps of Engineers as well as how she heard a lot about the effects of
climate change on people across the country while on the campaign trail in 2020. She
emphasized that she is excited to be a part of this team and Administration.

Mr. Carbonell reiterated that the leadership team is still getting started, and they are excited
about Administrator Michael Regan's recent confirmation by the Senate. He noted that they are
especially interested in hearing questions and thoughts about how EPA can best work with the
CAAAC moving forward.

Note: Mr. Joseph Goffman, the Acting Assistant Administrator and Principal Deputy Assistant
Administrator, joined late and introduced himself during the Questions and Answers portion of
the meeting.

Questions and Answers

Mr. Shoaff moderated the questions and answers portion of the meeting.

Mr. Tim Hunt stated that in the past, the group has talked about how to deal with the carbon
neutrality of biomass and the regulatory uncertainty around carbon accounting. He said he was
pleased to hear Mr. Carbonell mention the importance of using good science and noted that the
American Wood Council has provided information and research to EPA in the past and would be
happy to do so again. He asked what stakeholders can do to ensure that EPA's information needs
are being met and know what questions they have. Mr. Carbonell agreed that biomass is a
complex topic and that it is important to approach the law and the science carefully. He noted
that the EPA always welcomes input from the entire spectrum of stakeholders, including
technical and policy information, and he expects that will continue with the new Administration.
Ms. Nunez agreed and noted that they are still in the transition period, but they are listening to

2


-------
the priorities that different groups have and they welcome information that people send their
way.

Ms. Shannon Broome stated that one of the most valuable aspects of the CAAAC is the practical
experience that members have with implementing different rules and regulations, which is
something that regulators often are not as familiar with. She said she would like to see the
CAAAC take a more active role in advising EPA on how to implement different policy goals to
ensure their plans are accurate and workable in practice. Mr. Carbonell agreed that the diverse
perspectives and on the ground experience of CAAAC members are very valuable, and as a
former member he wants to make sure the EPA leverages that. Ms. Broome responded that in the
past, an Assistant Administrator would give a report to the group and then leave very quickly
without hearing much feedback, and in the future, more should be done in order to truly leverage
members' expertise.

Ms. Mary Peveto expressed Oregon's support for the new medium- and heavy-duty truck rules
and noted that she was happy to see Mr. Carbonell working for the EPA now after being a
member of the CAAAC. She explained that transportation continues to be a significant
contributor to carbon dioxide (CO2) emissions as well as air pollution and environmental justice
concerns, in part because of freight movement and a continued reliance on diesel. She stated that
she sees an opportunity to decrease these emissions because COVID-19 and other factors have
resulted in a massive decrease in transport, and she would like to see how the EPA can partner
with states and other parties to pursue a big investment in public transit, such as high speed rail.
She added that her organization did a study of diesel emissions from railroads and found that
Amtrak is the worst offender, and it would be very valuable to improve passenger rail and
interstate transit options in terms for air quality. She concluded by pointing out that although it is
valuable to pursue cleaner cars, it is equally if not more important to ask how we get people out
of cars. Ms. Nunez thanked Ms. Peveto for her feedback and emphasized that they will be
looking at many options and working with a variety of people to benefit communities.

Mr. Bob Meyers acknowledged that being a new appointee at EPA right now must feel like
"drinking from a firehose," and noted that there are a lot of big issues being dealt with on the
mobile sources side, including the California waiver and the ACE rule. He asked Ms. Nunez
whether she has any plans going forward in the heavy-duty sector related to outreach and
engagement. Ms. Nunez responded that the EPA was going to issue a rule under the previous
administration, but it did not go forward. She stated that this is one of the items that the office
will be examining alongside expert staff, and that addressing heavy-duty emissions is a priority.
Mr. Meyers followed up to ask whether greenhouse gas (GHG) emissions were a priority for
heavy-duty vehicles, and Ms. Nunez replied that the key issue right now is the NOx emissions
standard, but they may also be considering GHGs.

Mr. Clay Pope stated that each administration varies in how much they rely on the CAAAC, and
there wasn't much activity in 2020 other than the 50th anniversary report due to the pandemic.
He recommended that if the EPA is going to seek advice from the CAAAC, they should do so on

3


-------
more discrete and specific issues compared to the broadness of the report. He also asked whether
any of the EPA staff have heard about the initiative to install 600,000 vehicle charging stations
nationwide, and whether the Department of Transportation or the EPA would be managing that
program. Ms. Nunez answered that the EPA's job will be to look at emissions related to a
transition to more electric vehicles, and she indicated that the EPA likely did not have the
authority to be directly involved in infrastructure like that described. She noted that as they get
more information, they will do their best to relay it to everyone.

At this point, Mr. Goffman joined the meeting, and Mr. Shoaff invited him to introduce himself
to everyone.

Mr. Goffman apologized for being late and explained that he had been delayed by Administrator
Regan's inaugural staff meeting. He relayed Administrator Regan's message to the CAAAC: he
is committed to ensuring that the EPA carries out, to the best of its ability, President Biden's
environmental, climate, and environmental justice priorities, by using the best science, ensuring
public participation from all stakeholders, and ensuring transparency and integrity in decision-
making. Mr. Goffman acknowledged that CAAAC has been instrumental for a long time and
thanked everyone for their participation.

Ms. Gillian Mittelstaedt stated that she agreed that climate change and environmental justice are
two extremely important political and moral challenges. She went on to explain that although it
may appear less exciting and urgent, indoor air quality is very important, as 99% of exposure
occurs inside homes, schools, workplaces, and cars. She noted that the Clean Air Act does not
provide a regulatory framework for the EPA to address this issue, but in the short term, she
requests that OAR include this area in its budget and planning so it can be integrated across the
various programs. For example, when studying ultrafine particulate matter (PM), it is valuable to
consider infiltration rates as they contribute to exposure, risk, and human health. She encouraged
the EPA to make sure that the science and policy become integrated on this issue, which will
also help address environmental justice and some climate change topics, such as wildfire smoke.

Mr. Andrew Hoekzema thanked the EPA for scheduling this CAAAC meeting and explained
that compared to his experience with the previous administrative transition, he is glad to see that
so much attention is being paid to the CAAAC so early in President Biden's term. He stated that
he hopes this bodes well for the Biden Administration making more extensive use of members'
expertise and perspectives. He then brought up the ozone and PM National Ambient Air Quality
Standards (NAAQS) and the decision by the EPA under President Trump to leave the NAAQS
unchanged. He asked whether there is discussion about initiating a reconsideration of either of
those standards, given the new direction that EPA has taken to stick closer to the required 5-year
review period. He added that this is an example of the type of decision or consideration on which
it would be appropriate to solicit CAAAC feedback. He noted that although the EPA is not
required to consult with the CAAAC like it is with the Clean Air Scientific Advisory Committee
(CASAC), members have similar expertise and could be helpful. Mr. Goffman responded that
the EPA is reviewing this action, but that he could not elaborate very much, especially since such

4


-------
decisions are eventually up to the Administrator, and there hasn't been time to discuss it with
Administrator Regan yet. However, President Biden did task the agency to look at decisions
made under the previous Administration and set priorities, and the ozone and PM NAAQS are
under extensive scrutiny. He added that he would love to hear more in the future about how to
operationalize Mr. Hoekzema's suggestion that the CAAAC play a role in the NAAQS process.

Ms. Nancy Kruger explained to Mr. Goffman that before he joined, there had been some
discussion of how the new Administration could best use the CAAAC and asked him if he had
any thoughts on how to accomplish that. Mr. Goffman answered that Administrator Regan has
made a commitment for EPA to make full use of its available tools to advance its various
priorities. He stated that the EPA would benefit from the group's advice on discrete issues that
OAR can address.

Public Comments and Close of Meeting

Mr. Shoaff noted that the end of the meeting was approaching and paused the discussion to allow
an opportunity for public comment. Hearing none, he asked whether any of the EPA political
leadership had any final remarks and noted that he and Ms. Whitehurst would be happy to
receive thoughts, comments, or questions from members at a later time.

Mr. Goffman stated that he wanted to make it clear that the political leadership at EPA is eager
to make contact with stakeholders and get going in partnership with the scientific staff. He
thanked the CAAAC members for their willingness to participate.

Mr. Carbonell said that it was a pleasure to see everyone and reiterated that this meeting would
be the first of many interactions.

Ms. Nunez added that she looked forward to hearing everyone's input and getting help and
advice from the CAAAC as they begin to implement priorities alongside staff.

Ms. Kim thanked everyone for coming and stated that she was looking forward to working
together.

Ms. Whitehurst thanked the attendees and OAR leadership and reminded CAAAC members that
they are working on setting a date for the spring meeting, and she would let them know about
that soon. She then adjourned the meeting.
