Malay town Mayor Ciceron Cawaling on Tuesday said he is ready to face investigation and possible charges in relation to sewage problems hounding Boracay island.

"Well wala tayong magagawa but I have to defend myself kung pafile-an tayo ng kaso. Kahit hindi ko kasalanan yun kahit hindi kasalanan ng local government...kung may mga aksyon na ganyan, hindi naman siguro magpa-file ng kaso na walang due process," Cawaling told ABS-CBN News.

Department of Interior and Local Government (DILG) officer-in-charge Eduardo Año said the agency is waiting for results of the investigation on the situation in Boracay to determine what cases local authorities may face.

The DILG will assess how local officials issued permits and monitored establishments on the island, Año said.

Sanctions may range from suspension to dismissal, depending on the gravity of the offense, he added.

"We will make sure magiging accountable hindi lang ang local government, pati participation ng ibang agencies, ang local representative in the municipality of Malay, Aklan," he said.

Cawaling, meanwhile, said he supports the Department of Environment and Natural Resources' move to remove several establishments inside the island's "no build zone."

"Kailangan i-implement yun kasi marine zone yun eh. Alam naman nila yun," he said.

There are 18 businesses on the list of easement violators in Boracay's Station 1 beachfront area, officials said.
