(CNN) - Republicans on the Senate Environment and Public Works Committee, who last week boycotted a committee vote on Gina McCarthy to be President Obama's administrator of the EPA, will attend another vote scheduled Thursday after getting assurances from the agency that it will answer several questions posed by Republicans, a GOP committee aide told CNN.
EPA "committed to make some effort to follow up on the EPW Republicans five transparency requests," said Luke Bolar, an aide to Sen. David Vitter of Louisiana, the top Republican on the committee.
Last week's boycott frustrated committee Democrats who, with one of their own members out sick, could not get a quorum without at least two Republicans present. To get around that problem this week, Sen. Frank Lautenberg, D-New Jersey, planned to travel to DC for the vote despite an ongoing illness.
It's not clear if the lifting of the boycott will translate into GOP votes for McCarthy, who is currently an assistant administrator at the agency.
A committee vote is scheduled for noon.
