The official’s updated recusal statement shows work for 11 former clients, including a biofuels group and a major oil and gas industry services provider.

A top political appointee in EPA’s air office has agreed to temporarily steer clear of “particular” matters pertaining to almost a dozen former clients with a stake in biofuel regulations or other policies.

Alex Dominguez, deputy assistant administrator for mobile sources, bowed out of involvement in matters related to the National Corn Growers Association; Texas power producer NRG; and Oneok, an Oklahoma-based oil and gas industry services provider, according to an amended April recusal statement obtained by POLITICO’s E&E News under the Freedom of Information Act.

The three are among 11 former clients listed on the statement, stemming from Dominguez’s work for the lobbying firm now known as Massie Partners before returning to EPA as President Donald Trump took office in January for a second term.

The recusal periods run no later than this coming January and do not preclude Dominguez from meanwhile tackling broader regulatory work that could affect those clients and others. Examples of matters involving specific parties from which he must recuse himself include contracts, judicial proceedings and investigations, according to federal ethics rules footnoted on the statement.
