The Bungoma Public Investment and Accounts Committee will investigate whether the executive paid Sh10 million to construct of the Tuuti dumpsite.
The committee, chaired by Mjini MCA Joseph Maguda, will summon Environment executive Stephen Kokonya and other officers involved in the project to answer queries.
It will table a report in the county assembly within 21 days.
In a statement, Kokonya denied a contract was awarded to construct the dumpsite.
The statement was read by Peter Cherui, the chairperson for the Committee on Environment, Tourism and Natural Resources.
Governor Kenneth Lusaka on Tuesday appointed Kokonya to head the Health docket.
Assembly speaker John Makali said there are conflicting reports on whether the money has been paid to the contractor or not.
“Evidence from the IFMIS system shows money was paid for the project but Kokonya says no payment was made,” he said.
Marakaru Tuuti MCA Joseph Nyongesa had asked for the name of the contractor, the progress of implementation and the amount of money spent.
The county had listed the project as an achievement.
