MALOLOS CITY—While dams in Central Luzon remain safe after the
5.4 earthquake that hit Baler, Aurora on April 4, a dam safety expert advised
that a thorough monitoring and assessment on structures be conducted.
Engineer Roderick Dela Cruz, a Bulakenyo dam safety expert based
in California said that in the United States, they immediate conduct the same
after an earthquake of at least magnitude 5.
“We want to be sure of the safety of our facilities,” said
during his presentation on dam safety here on Thursday afternoon, April 4 hours
after the earthquake.
As lead dam safety engineer of Southern California Edison (SCE), Dela Cruz manages 82 large dams with age range of 80 to 100 years old.
He said that immediate monitoring and assessment of dam
structures especially dikes and spillways are important to see its integrity.
The said actions are mandated by US state and federal laws on dam safety that set standards in the management of dams.
He said that it is unfortunate that in the Philippines there is
no law yet that cover dam safety which will also set standards in dam
management.
“There are many stake holders in dam operations in the
Philippines, but there is no single office that monitors the dam because there
no law on dam safety,” he said.
He also lamented Congress’s slow pace on the ratification of the
proposed bill for a national dam safety program.
However, he remained optimistic that advocacy n dam safety can
be taken by local government units through the enactment of provincial
ordinance on the same concern.
This was affirmed by Governor Wilhelmino Alvarado in an
interview after Dela Cruz’s presentation.
Alvarado vowed that he will coordinate with the Sangguniang
Panglalawigan of Bulacan to pass a local ordinance on dam safety.
He said that a local ordinance can later be improved by
Congress, and will serve as their basis in passing a national law which takes
time.
Meawhile, the National Power Corporation (Napocor) made
assurance that Angat Dam in Hilltop,Norzagaray town is safe after the recent
earthquake.
Engineer Rodolfo German,the general manager of the Angat River
Hydroelectric Power Plant (Arhepp) said that Thursday’s earthquake was hardly
felt at the dam.
However,he said that Napoco Dams and Waterways division along
with representatives of the Philippine Institute of Volcanology and Seismology
were tasked to conduct monitoring and assessment of dam structures.
Constructed 43-years ago, Angat Dam is facing its first major
rehabilitation due to the presence of a splay of the Marikina West Valley
Faultline near the dam’s dike.
The Aquino Administration has allocated P5.7-Billion for the
said rehabilitation but the bidding for the construction still have to be
conducted. Dino Balabo
