MALOLOS CITY—Recent disasters in the Visayas kept dam operators and local officials in Bulacan preparing for possible Angat Dam Break.

Liz Mungcal, head of the Provincial Disaster Risk Reduction Management Office (PDRRMO) said that before the Bohol earthquake struck, they have been meeting with dam operators.

This includes operators of the Angat, Ipo and Butos Dam, along with officials of the Metropolitan Waterworks and Sewerage System (MWSS), and the Common Purpose Facilities (CPF).

“We have to prepare in anticipation for disaster that will be brought by possible break of the Angat Dam,” said Muncgal in the sidelines of the meeting of members of the Angat Dam break technical working group at the La Mesa Dam in Novaliches, Quezon City on Tuesday, November 12.

Mungcal noted that Angat Dam break can occur anytime if  case of movements in the  Marikina West Valley Faultline (MWVF).

The same was echoed by members of the TWG who noted that the disaster woild be unimaginable.

To prepare for such possibilities, Mungcal said the provincial government in coordination with the National Power Corporation (Napocor) and the Engineering Development Corporation of the Philippines (Edcop) had prepared an emergency action plan (EAP).

The said EAP will be presented to Bulacan and Pampanga mayors and disaster officers next week.

Some of the inputs on the said EAP is the establishment of early warning system (EWS), evacuation routes and possible mass evacuation center.

Some of the evacuation areas identified are located in the upland areas of Bulacan, Pampanga and Nueva Ecija.

Based on simulation study conducted by Tonkin & Taylor International and Edcop, a wall water rising to 10 to 30 meters will rush out into the Angat River within hours in case of a dam break.

The said on rush of water is said to wipe everything on its path that will make damages left by earthquake in Bohol and typhoon Yolanda in Visayas as a thing of the past.

Disaster officials said that it will initially damage Bulacan, but the long term effect will be in Metro Manila which will ran out of water for months.

This is due to the fact that Metro Manila is drawing 97 percent of its potable water requirement  from Angat Dam.   Dino Balabo

Bulacan to send medical team to typhoon hit areas

MALOLOS CITY—Bulacan is sending a 54-man medical team to coastal towns of Leyte and Samar in an effort to assist victims of typhoon Yolanda which has not be reached by humanitarian groups and other government agencies.

Governor Wilhelmino Alvarado said the medical team will be composed of 24 doctors and 24 nurses from 21 towns and three cities of the province, along with six medical specialists from the Bulacan medical center.

The said team will leave Bulacan on Sunday, along with relief goods collected from Bulakenyos and will be delivered to victims of typhoon Yolanda.

The governor said that the medical team and relief goods will be transported using a ship owned by a member of the Philippine Medical Association (PMA).

The said ship will also serve as temporary residence and clinic of the medical teams as there is hardly a hotel to accommodate them in the typhoon hit areas.

“Our medical team will ride along with the first batch of PMA members that will be sent to the coastal towns of Leyte and Samar,” he said.

Alvarado explained that many coastal towns of Samar and Leyte are still to be reached by humanitarian groups and government personnel delivering assistance and relief goods.

With regards to relief goods, Alvarado called on Bulakenyos to bring their donations to the provincial capitol in this city, where a donation center was established since Tuesday.

However, he drew flak when asked in a live interview by Radyo Bulacan on how much will be the pledge of the provincial government to victims of calamity in the Visayas.

Alvarado answered,” hindi na ninyo dapat alamin kung magkano ang ibibigay ng kapitolyo.”

He then said that the provincial government will spend money for the medicines and other supplies that will be used by the medical team, but did not specified the amount.

Alvarado also said that for the victims of typhoon Sendong in Mindanao in 2011, they collected a total P1.5-Million donation from Bulakenyos, and the provincial government gave a total of P2.5-Million as counterpart.

Despite the governor’s recitation of facts from previous relief efforts of Bulacan, Bulakenyo social media users demanded transparency on the amount that the provincial government will spend.

Some noted that the funds of the provincial government are actually peoples’ money and the government must account for every cent spent.

MALOLOS CITY—At least 13 villages in San Miguel, Bulacan were hit by flash floods twice on Sunday, and local officials blamed it on alleged mining operations in Sierra Madre mountains in the eastern part of the province.

The flash floods came on a sunny weekend, a day after Supertyphoon Yolanda moved out of the Philippine area of responsibility. Mayor Roderick Tiongson of San Miguel said they were surprised by the flash floods because it was sunny in Bulacan since Saturday morning.

“We believe it is due to on-going mining operations in Sierra Madre,” he said referring to a company involved in extraction of iron ore in Barangay Camachin in the mountain town of Donya Remedios Trinidad (DRT).

Tiongson also lamented the sorry state of Sierra Madre on the east side of his town noting that for years it has been subjected to marble quarrying, and iron ore mining.

“The damage has been done and our kababayan in San Miguel are suffering, especially the farmers,” he said referring to flash floods from Sunday morning to evening. He said that 13 of the 49 villages of San Miguel were inundated by flash floods which reached chest high deeep.

The flooded villages included Baritan, Cambio, Maligaya, Barias, Salacot, Balite, Bantog, Sta. Lucia, King Kabayo, Penambaran, Ilog Bulo, Pulong Duhat and Bagong Silang. Meanwhile, the Provincial Disaster Risk Reduction Management Office (PDRRMO) of Bulacan allayed fears over possible flood with the water discharges from Angat, Ipo and Bustos Dams.

Raul Agustin, head of special operations of PDRRMO, said that its effect would be minimal noting that there is no back flood coming from Pampanga, while sea water rise is low. He also said that since Saturday, they recorded little or no rainfall in most parts of the province.

As of Monday morning, Angat Dam increased its water discharge to 265 cubic meters per second through its spillway, while Bustos Dam is discharging a total of 285 cms. Agustin said there is nothing to worry over the water spilled from the dams.

“If they are spilling 600 cms and above, we should start to worry,” Agustin said. On Sunday, Angat Dam started spilling 130 cms as water elevation climbed to 213.65 masl. Yesterday morning, water elevation dropped to

213.51 masl.

Engineer Rodolfo German said they will continue to spill water until the water elevation dropped to 210 masl which he described as “comfortable level.” Dino Balabo

Angat Dam breaches 213 meter level, spills water

MALOLOS CITY—Water elevation at the Angat Dam climbed to 213 meters above sea level (masl) on Sunday, leading the National Power Corporation (Napocor) to discharge water through its spill way for the first time this year.

This came a day after Super typhoon Yolanda move out of the Philippine Area of Responsibility (PAR) but left heavy rainfall infl ow into the dam reservoir.

Gladys Sta. Rita, president of the Napocor, told PromdiNews that Angat Dam started discharging a total of 190 to 200 cubic meters per second (cms) of water. She said that Napocor opened its floodgate by one meter to discharge at least 130 cms through its spillway.

In addition to that, Napocor is also discharging 61 cms through its tunnels to power its hydroelectric turbines that generate electricity. As of yesterday morning, water discharged by Napocor through Angat Dam’s spillway was raised to 265 cms, while Bustos Dam on the Angat River downstream is discharging 285 cms.

The discharge through the dam’s spillway is the first this year, after months of clamor from Bulacan officials for Napocor to start “pre-emptive release” of water. On Saturday, water elevation at the dam climbed to 211.25 masl, but Engineer Rodolfo German said they would not spill water yet.

German is the general manager of the Angat River Hydroelectric Power Plant (ARHEPP) of the Napocor which manages the Angat Dam. German later said that they can spill water anytime, while the Napocor central office issued an advisory within the next 24 hours as they monitored situation at Angat Dam.

Based on data gathered by PromdiNews on Saturday, Yolanda’s rains left an infl ow of at least 568 cms, while the regular discharge of Angat Dam towards Ipo Dam is only 61 cms. This means more than 500 cms of inflow that caused water elevation to climb.

Yesterday, the inflow dropped to around 300 cms, and water elevation dropped to 213.51 masl from Sunday’s 213.65 masl. As this develop, the Provincial Disaster Risk Reduction Management Offi ce (PDRRMO) of Bulacan allayed fears of possible floods.

Liz Mungcal of the PDRRMO said that the 130 cms discharge to Angat River is almost negligible noting that there is not much rains in the last 24-hours and that rivers are shallow because of low tide. For his part, Engineer Precioso Punzalan of the National Irrigation Administration (NIA) said that Bustos Dam can accommodate water spilled from Angat Dam.

Operated by NIA, Bustos Dam is an after bay regulator dam of the bigger Angat Dam. Punzalan said they have been discharging 60 to 90 cms from Bustos Dam since Thursday in preparation for the Angat Dam discharge.

On Saturday, Gov. Wilhelmino Alvarado expressed disappointment over the refusal of Napocor to spill water despite the fact that its 210 spilling level was breached on Friday night. But Napocor officials like Engineers Romualdo Beltran and Russel Rigor explained that the 210 masl is not their spilling level but the normal high water level during flood season.

As head of the Dams Management Division of the Napocor, Beltran noted that the month of November normally marks the end of rainy season and the start of the summer. However, he said that Napocor is also considering typhoons that can hit the country between the end of November to December and January next year.

Angat Dam breaches 210 meters water level, but wont spill yet

Angat Dam in Norzagaray, Bulacan.

MALOLOS CITY—Water elevation at the giant Angat Dam climbed by 2.65 meters in 24 hours breaching its spilling level of 210 meters above sea level (masl) due to rains brought by super typhoon Yolanda.

However, the National Power Corporation which manages the dam said they will not spill water yet; and added that 210 meters is “normal high water level during flood season.”

Records showed that water elevation at the Angat Dam climbed to 211.25 masl at 9AM yesterday, from 208.60 masl on Friday.

According to Engineer Rodolfo German, Angat Dam which supplies 97 percent of Metro manila’s potable water requirement can hold up to 217.4 masl.

German is the the general manager of the Angat River Hydroelectric Power Plant (ARHEPP) of the Napocor.

He stressed that they will only spill water if there is another typhoon coming towards dam and will bring more rains.

“Malaki pa ang factor of safety, but we can spill water anytime,” he said.

As of Saturday, he said there is no coming weather disturbance based on latest weather forecasts.

With regards to stability of structures of the 47 year old dam, German expressed confidence.

He also said that water inflow coming down Sierra Madre mountain is estimated at 568 cubic meter per seconds (cms) while outflow through their power tunnels that feeds water to Arhepp’s power turbines is only 61 cms.

German also estimated that water elevation at the dam will further climb to 214 masl in the next 24 hours.

For his part, Engineer Russel Rigor, head of the flood forecasting division of the Napocor explained that the 201 masl is not necessarily the spilling level.

He described it as the normal high water level.

With regards to the Umiray Angat Transbasin Tunnel (UATP), German and Rigor said they don’t know if it is still open.

German earlier said that it will be closed once water elevation at the Angat Dam reached 210 masl, but Rigor added that it is the responsibility of the Metropolitan Waterworks and Sewerage System.

The 13-Kilometer UATP divert water from Umiray River in Quezon Province to Angat Dam.

With regards to decision on spilling water in the Angat River, German admitted that when water elevation at the dam claimed to 210 masl, it is the Napocor’s decision.

He said that National Water Resource Board (NWRB) only makes decision on water release when elevation is below 210 masl.

As this develop, Bulacan Governor Wilhelmino Alvarado reiterate his call for preemptive water release of dams in the province including Angat Dam.

In his weekly broadcast aired over Radyo Bulacan on Saturday, the governor expressed apprehension on possible flooding in the province in case Angat Dam spill water.

“Hindi na natin dapat hintaying umapaw, pagkatapos ay biglaan silang magpapatapon ng malaking volume, tiyak na babahain na naman ang Hagonoy at Calumpit,” Alvarado said.

He also expressed concerned over the stability of the dam noting that President Aquino have allocated P5.7-Billion for its rehabilitation.

The said rehabilitation is mean to improve stability of Angat Dam in case of possible magnitude 7.2 earthquake that will be generated by the possible movement of the Marikina West Valley Faultline (MWVF).

But sources recently disclosed that the possible earthquake was used in justifying the rehabilitation of the dam whose main purpose is to increase its water holding capacity to meet the increasing needs of Metro Manila. 

MNTC to confer safety awards to outstanding drivers, firms

MALOLOS CITY—The Manila North Tollways Corp. (MNTC), builder of and concessionaire of the 90-kilometer North Luzon Expressway (NLEx) is set to confer recognition to outstanding companies that pursues road safety in using the expressway.

Dubbed as the NLEXcellence Safety Awards, 15 awardees will be feted next week at the SM Mall of Asia Convention Center (SMX). Rodrigo Franco, president and CEO of the MNTC, said the awardees include bus and trucking companies who share the same values on road safety as the NLEx.

He said the ingrained culture of safety by both the MNTC and Tollways Management Corporation (TMC), the operator of NLEx, is what sets NLEx apart.

However, joint MNTC-TMC advocacy and mission for road safety cannot be successful without the support and cooperation of drivers and operators of vehicles using the expressways, he added.

As a tribute to responsible partners in road safety, the MNTC has been giving recognition to outstanding companies. However, they restructured the award’s mechanics and criteria this year to further highlight NLEx’s strong advocacy on road safety.

Franco said that in the NLEXcellence award, bus and truck companies will be recognized for exemplary performance in ensuring safety on the road.

“The NLEXcellence Safety Awards demonstrates how deeply we recognize safety as shared value between the awardees and ourselves,” he said. Franco further said “the awards is touted to be a testament of the company’s strengths and capabilities, the quality of its personnel, products and services.

It redounds to the companies reliability and dependability, generates client’s trust and confidence, industry respect and prestige which could lead more business and opportunities for the awardees.”

The awards will have the following categories: vehicle quality, driver’s professionalism, and company operational excellence. Nominees in the vehicle quality category are assessed based on vehicles’ roadworthiness, specifically the condition of vehicle’s engine, tires, breaks, lights, the presence of safety devices and emergency tools, presence of required documents, as well as vehicles’ cleanliness and comfort of the driver and his assistant.

In the driver’s professionalism category, nominees are evaluated based on their skills in driving, knowledge of traffic rules, regulations and signs, physical fitness, health and presentable appearance, apprehension record, their regulatory compliance, and driving qualifications.

In the company operational excellence category, companies are assessed on the basis of their safety record, company policies, and programs physical examination of drivers that may include drugs and alcohol tests, regular skills training, and behavioral workshops, close management supervision.

The company should also have an extensive vehicle care program such as regular pre-emptive maintenance, mandatory replacement of tires and other wearing parts, like break-pads, clutch, belts, filters, and others.

The vehicle should also be washed and cleaned regularly. The garage or motorpool should also be clean and adequately equipped to handle most if not all repair and maintenance work by a qualified mechanic.

Franco said that criteria for each category follow a track towards building an expressway environment where travelers will have peace of mind, as they travel safely, comfortably and conveniently.

Bulacan legislator to file charges vs.DPWH

MALOLOS CITY—A Bulacan provincial board member warned of filing charges against the Department of Public Works and Highways (DPWH) for improper implementation of infrastructure projects in the province.

This came as DPWH officials drew flak for the road-widening project along the MacArthur Highway here while public utilities posts have not been transferred.

Records showed that about 1,000 electric and telephone posts have encroached on the road right of way of the Manila North Road or the MacArthur Highway from Meycauayan City Calumpit town.

“I will definitely file charges against the DPWH if they will issue certifi cate of completion to their contractors,” Board Member Michael Fermin said. He said that implementation of road widening project along the MacArthur Highway is “improper.”

Fermin said that over 200 posts are still on the way of drainage canals being constructed or within the road right of way. “That’s a clear misuse of public funds and bad stewardship of people’s money,” he said.

The Senior Board Member also noted that more than a week ago, the said drainage canal was repaired even if the project is not completed yet. “They upgraded the canal and if they spent P2 million with it the first time  constructed the canal, they spent the same for the repair,” he said.

Fermin also blamed the DPWH for lack of consultation with local government units before implementing the project. He also expressed dismay over the lack of monitoring and assessment by provincial and city engineering offices on the said project.

“I wonder why,” Fermin said and added, “they should have the last word before the implementation.”

For his part, Engineer Glenn Reyes, head of the Provincial Engineering Office (PEO) said they conduct monitoring on the said projects. But when asked if PEO conducts on-site monitoring and ocular inspection during the implementation of the project, Reyes said they only receive reports from the DPWH.

With regards to relocation of public utilities posts along the MacArthur Highway, Engineer Ruel Angeles said they have been coordinating with public utilities companies, but their requests to relocate posts were disregarded.

He added that since they started implementing road widening along the MacArthur Highway in 2005, they had already sent requests. However, Fermin and Gov, Wilhelmino Alvarado said public utilities companies responded by relocating some of the posts in Guiguinto town and in Barangay Dakila in this city.

Fermin stressed that lack of [proper coordination in the implementation of said road widening project will cost the government a lot money.
