Mr. Kevin S. Minoli Designated Agency Ethics Official U.S. EPA (2310A) 1200 Pennsylvania Avenue, NW Washington, DC 20460 Dear Mr. Minoli: The purpose of this letter is to describe the steps that I will take to avoid any actual or apparent conflict of interest in the event that I am confirmed for the position of Assistant Administrator for the Office of Air and Radiation of the United States Environmental Protection Agency. As required by 18 U.S.C. 208(a), I will not participate personally and substantially in any particular matter in which I know that I have a financial interest directly and predictably affected by the matter, or in which I know that a person whose interests are imputed to me has a financial interest directly and predictably affected by the matter, unless I first obtain a written waiver, pursuant to 18 U.S.C. 208(b)(1), or qualify for a regulatory exemption, pursuant to 18 U.S.C. 208(b)(2). I understand that the interests of the following persons are imputed to me: any spouse or minor child of mine; any general partner of a partnership in which I am a limited or general partner; any organization in which I serve as officer, director, trustee, general partner or employee; and any person or organization with which I am negotiating or have an arrangement concerning prospective employment. Upon confirmation, I will resign from my position with the law firm of with Hunton & Williams LLP. I currently have a capital account with the firm, and I will receive a refund of that account after my resignation. Until I have received this refund, I will not participate personally and substantially in any particular matter that to my knowledge has a direct and predictable effect on the ability or willingness of the firm to pay this refund, unless I first obtain a written waiver, pursuant to 18 U.S.C. 208(b)(1). I will continue to receive my monthly draw at the current rate until I resign from the law firm. I will not qualify for any additional partnership payments. If the law firm decides to pay me a discretionary partnership distribution for work I performed during the firm's fiscal year ending March 31, 2018,1will not accept that distribution and will forfeit it, unless I receive it before I assume the duties of the position of Assistant Administrator for the Office of Air and Radiation. If I receive the discretionary partnership distribution, I will not participate personally and substantially in any particular matter involving specific parties in which I know the law firm is a party or represents a party for a period of two years from the date on which I receive the distribution. If I do not receive the distribution, I will not participate personally and substantially in any particular matter involving specific parties in which I know the firm is a party or represents a party for a period of one year from the date of my resignation, unless I am first authorized to participate, pursuant to 5 C.F.R. 2635.502(d). In addition, I will not participate personally and substantially in any particular matter involving specific parties in which I know a former client of mine is a party or represents a party for a period of one year after I last provided service to that client, unless I am first authorized to participate, pursuant to 5 C.F.R. 2635.502(d).

EPA 18cv3472 NDCA Tier 1 ED 002061 00129423-00001 If I have a managed account or otherwise use the services of an investment professional during my appointment, I will ensure that the account manager or investment professional obtains my prior approval on a case-by-case basis for the purchase of any assets other than cash, cash equivalents, investment funds that qualify for the exemption at 5 C.F.R. 2640.201(a), obligations of the United States, or municipal bonds.
