LLDA/LLRP are they the same management?. If so, does it mean that our approved projects are dead too.? I tend to believe that the current president is right to cancel it, it has too many loopholes that too many hands in the cookie jar is involved. In 5 yrs. Aquino will be gone too.Hopefully, his administration will act faster to get the clean-up program rolling, otherwise will never get to see it happen. Laguna lake is in deep trouble..

The Laguna Lake Rehabilitation Project (LLRP) is under the national
government with the Department of Public Works and Highways (DPWH)
and the Department of Environment and Natural Resources (DENR).

The Laguna Lake Development Authority (LLDA) is a government
corporation that runs under DENR.

The subprojects in Paete (SLF/MRF and WWTF) are under the
The Laguna de Bay Institutional Strengthening and Community
Participation (LISCOP) project, which is currently on its second
five-year development initiative (2009-2013), which was made
possible by a 10 million dollar loan from the World Bank. LISCOP
projects are meant to be seed programs for the communities.
These are independent from the larger rahabilitation project
called LLRP. LISCOP is administered by the LLDA.

The LLRP, which was proposed by Arroyo's administration, involves
dredging the lake using an 18B PHP loan from the Belgians. This
is the project that has been canceled by the Aquino administration.
What this means is that the LLRP is back to the drawing board.
For this reason, the LLDA has authored a new plan, which has
already been posted under this thread. The plan is just a
framework at the moment - there is no funding yet, in other
words, it is just a dream.

The subprojects in Paete are proceeding as planned. The
feasibility study and detailed architectural and engineering
design for the proposed sanitary landfill and materials recovery
facility have been finished and submitted by the Paete's
municipal engineer. There are minor corrections but the final
version will be submitted next Friday. The Sangguniang Bayan
now needs to authorize the signing of a Memorandum of
Agreement with the LLDA and the World Bank for the waste
water treatment facility. And the LLDA anticipates the bidding to
begin sometime in November.

I thought we should thank those who had the foresight & tenacity,
including those who supported to get these subprojects going.
With the ro-co (roller coaster) projects mentioned above,
who knows when any of those will materialize.

The subprojects provide more immediate benefits to the Paetenians. Just the
thought that these are going to happen makes me feel proud that Paete has
chosen to move forward. So as Mr. Ming Baldemor has expressed, sana po
our future municipal leaders (not only the provincial & national leaders) ay
huwag bibitaw (o bibitiw) sa proyektong ito sa pagdaan ng mga taon.
Kung minsan dahil nga sa ikli ng panunungkulan ay hindi natatakpusan
ang mga sinimulan at ang mga bagong halal lalo't kalaban sa pulitika ay
ayaw ipagpatuloy ang naiwan ng sinundang nanungkulan

The commercialization of Laguna de Bay gives me the butterflies. True, there
will be more jobs, but there will also be a lot of competition from non-locals
who would be coming to dig gold where gold may be found. Fine if we could
accommodate the influx of tourists and new settlers alike. We'd need more
housing, better infrastructures & adequate utilities. Such a dramatic change
might sprint progress ahead of the community which could spell disaster. Even
a leader nation like America suffers the consequences of going too fast too soon.

And the the chunk of gain goes back to the investors. Ouch!

Back to now. Thank you, Paete for this good act for your people!

Thank you for seeing how the subprojects fit into the larger picture.
This was not emphasized in the discussion because the subprojects
will benefit Paete directly. How the subprojects fit into the big
picture of the rehabilitation of Laguna de Bay is the argument
required to direct the national government to what it should do
first. And I think Paete's subprojects are in line with the vision of
the World Bank. This is the reason why the World Bank was more
than accomodating and eager to support Paete.

LLRP requires a careful study and planning. It is huge and
prioritization is a must. There are various components of the
project and it is necessary that an order is made with regard
to which ones should be executed first. Reforestation, wastewater
treatment, and solid waste management are the first steps. And
as you correctly noted, the second one is the community of
settlers along the shore.

Laguna joins eco groups’ call for corporate accountability in protecting freshwater sources

CALAMBA, Laguna, Sept. 17 (PNA) -– The province of Laguna joins Greenpeace and the EcoWaste Coalition in calling on businesses for a full public disclosure of their toxic effluents, especially into freshwater bodies.

The call was made during this year’s International Coastal Clean-up Day (ICC) activities at the Calamba Baywalk in Barangay Aplaya this city.

“Our freshwater bodies are heavily under threat from invisible contaminants coming from industrial discharges,” said Beau Baconguis, anti-toxic campaigner of Greenpeace Southeast Asia.

“Currently, there are no systems allowing the public access to information that would help them protect themselves from toxic effluents into water sources. Greenpeace is therefore recommending the set-up of a Pollution Release and Transfer Register (PRTR), which would provide the public with a database system from which they could check the health of their water sources and identify hotspots. We are looking forward to working with the whole province of Laguna in refining such practical solutions for water protection,” he said.

Greenpeace said that industries would also benefit from participating in a PRTR as the registry provides them with a comprehensive measurement to check, compare and improve their processes, and make their businesses more viable, aside from being able to contribute to the betterment of the situation that freshwater sources face.

For the last two months, Greenpeace has been at the forefront of an international initiative to get the world’s top clothing companies to commit to detoxify their products, production lines and supply lines. Kicking off the campaign was a two-part report released by Greenpeace, called “Dirty Laundry”, detailing results of an investigation into pollution of China’s rivers that link clothing giants and tracking back the chain of custody into the Philippines and other markets.

The “Detox” campaign has so far been successful in getting the top three sports apparel companies, Nike, Adidas and Puma, to commit to completely eliminate toxics by 2020.

According to Laguna governor Emilio Ramon “E.R.” Ejercito, “Laguna de Bay is a source of livelihood, food and freshwater, which is why ‘Save Laguna de Bay’ is one of the priority projects of the province. Those who will benefit directly from the rehabilitation of the lake will not only be Laguna, but Metro Manila as well.

The lake is the next most important freshwater source for the nation’s capital and therefore the responsibility of citizens and businesses alike to protect and nurture. Government and civil society need the help of individuals and businesses if we are to avert a water crisis, which will affect not just our drinking water, but our agriculture and livelihood as well.”

Laguna is among the provinces and towns that have progressive waste management initiatives, which include efforts to ban the use of plastic bags. Results from the waste audit, conducted at the Manila Bay by Global Alliance for Incinerator Alternatives (GAIA), Greenpeace, EcoWaste Coalition and other partners in November 2010, show that plastics comprise majority (75.5 percent) of the trash people discard into the water.

“We are conducting a comprehensive waste audit as the central activity of this year’s ICC in Laguna de Bay, where we believe plastics will still be at the top of the list of what we collect. This is why programs to curb the use of plastic bags, such as those undertaken by Laguna and other progressive provinces, cities and municipalities, will be a big contribution towards the protection of our freshwater resources,” said Rei Panaligan, coordinator of EcoWaste Coalition.

“Schools, barangays, towns and cities would do well to cut down their volume of solid waste and implement ecological waste management programs, while industries should, in addition, make sure that their chemical discharges are kept in check. Clean-ups are good, but if we protect our waters at the source of pollutions, there would be so much less problems.”

The clean-up in Laguna de Bay is in the fourth year of a partnership that was initiated by Greenpeace with the EcoWaste Coalition and the Laguna Youth Development Affairs Office. (PNA)

The Pambansang Lakas ng Kilusang Mamamalakaya ng Pilipinas (Pamalakaya) and the Save Laguna Lake Movement (SLLM) has assailed the government plan to implement the P300-billion, 10-year Laguna Lake Master Plan (LLMP), which is worse than the scrapped P18.7-billion Laguna Lake Dredging Project (LLRP).

Pamalakaya national chairman Fernando Hicap and SLLM convenor Pedro Gonzalez also twitted Malacañang for trying to lure the Belgian government into financing components of the LLMP after banging away at the LLRP, which was proposed by Baggerwerken Decloedt en Zoon (BDC) and approved in February 2010 and thrice upheld as valid, legal, and binding by the Department of Justice (DoJ).

BDC spent P400 million to conduct studies at the Laguna de Bay for four years and worked to secure Official Development Assistance (ODA) from the Belgian government only for President Benigno S. Aquino III to slam the project twice in major policy speeches.

Pamalakaya and SLLM have attacked the LLMP for being an extravagant means of privatizing the lake and are now putting Aquino to task for flip-flopping on the LLRP, which was scrapped on the basis of a claim that the 4.2-million cubic meters of silt to be recovered would be dumped in another part of the lake.

Reports have it that Chinese corporations would be involved in the P300-billion project and its 54 sub-projects.

Aquino claimed the LLRP does not have a resettlement component and will not be involved in protecting the Marikina Watershed, the source of millions of tons of silt.

Both have been incorporated into the project, BDC officials said, but Malacañang apparently did not read the contract and failed to appreciate the fact that P2.4 billion would be allotted for the relocation of families in the event they are affected.

Hicap and Gonzalez said it appears Aquino and his Cabinet members cannot make up their mind since BDC had already sued the government before the International Center for the Settlement of Investment Disputes (ICSID) in Washington D. C. and the Belgian government has apparently shot down investments by its companies here.

Many of the 27 member-nations of the European Union (EU) are not biting the offer of Aquino to participate in the Public-Private Partnership (PPP) program due to the dispute with BDC.

Under this situation, they added, it would appear that the government is so desperate for funds that it cajoling the Belgians to talk again so the money allotted could be channeled to other projects.

Why Laguna Lake water isn't safe for people or fish
09/24/2011 | 04:16 PM

A toxic, biochemical soup seasoned with more than a few pinches of heavy metals and enriched with aromatic flavors of wastewater from piggeries, poultry farms, homes and some factories. For texture, the sludge may have some chunks of common, non-biodegradeable solid waste like plastic and rubber.

The Laguna Lake Development Authority’s (LLDA's) latest analyses of water samples from the lake and the rivers and streams flowing into it show low dissolved oxygen, high dissolved nitrogen, some concentrations of lead and cadmium, elevated levels of phosphates, oil and grease, and high levels of fecal coliforms.

Simply put, Laguna Lake and its tributaries are heavily polluted and dying. Various studies over the years have ascertained that much of the pollution comes from the homes along the rivers and streams and significant contributors to the poisonous soup that flows to the lake are the backyard piggeries.

LLDA water sampling data also have a significant hole. No tests are being done on waters flowing through the densely populated areas of Taguig City in Metro Manila and San Pedro, Binan and Sta. Rosa in Laguna.

The same data also indicate that only the areas of East Bay, Central Bay, Northern West Bay and South Bay often have better water quality than the rest of the areas that the LLDA monitors. Commercial fishing proliferates in these sections of the lake.

In contrast, the most toxic and foul are the rivers of Marikina, Mangangate, Tunasan, San Pedro, Cabuyao, San Cristobal, San Juan, Bay, Sta. Cruz, Pagsanjan, and Sapang Baho. These are 11 of the 15 monitoring points. The other rivers have slightly lower pollution levels, but are still heavily polluted nevertheless.

Basic lab science

In an interview with GMA News Online, recently-appointed Presidential Adviser for Environmental Protection Nereus Acosta, who is also concurrent member of the LLDA Board, said the science laboratory of the LLDA was one of the first offices he visited.

“I went first to the laboratory. You can enforce better kung tututukan yung sampling ng water. Sana at least one week straight at surprise ang timing. Sa gabi at maulan doon sila nagre-release ng kanilang waste," Acosta said.

LLDA water samples are taken monthly. Acosta learned that the lab had 20 plus personnel, with sufficient education and training, but whose capabilities are limited by lack of equipment, devices and supplies. The lab processes water samples within a week to 10 days.

"Your basis for enforcement is the science. LLDA needs a permanent home, a building with a laboratory. Some laboratory equipment and devices are sensitive and do not function at optimum in temporary work spaces," Acosta said.

Last year, former LLDA General Manager Edgardo Manda tried to give the agency its own facilities, but that project hit a snag in the form of an alleged corrupt deal.

LLDA finances also caught President Benigno Aquino III’s attention. He ordered cancelled the P18.5 billion lake dredging project after determining that it did not effectively address the lake’s major problems.

While the lake agency awaits permanent quarters and funds, the president’s environment adviser said he will work on having linkages with institutions like the University of the Philippines in Los Baños (UPLB), which has a School of Environmental Science and Management (SESAM).

He explained that crucial to the success of the MMDA are getting the metrics and mapping done. “You can’t manage what you can’t measure. You can’t see what you can’t map," goes part of the Acosta mantra.

Environment management and food safety

In the supply chain management approach to food safety known as “farm to fork" —practiced widely in Europe, North America and industrialized parts of Asia— experts pay meticulous attention to environment management practices at food sources.

According to a study entitled ‘A Survey of Waste Management Practices of Selected Swine and Poultry Farms in Laguna, Philippines’, most of the farms practice ‘effluent management’ or the flush their waste into the lake.

The study was conducted in thirteen municipalities of Laguna Province by researchers of UPLB. They surveyed 80 smallholder and nine commercial swine farms with a total animal population of 15,917 pigs.

Lakeshore municipalities that were included were Los Baños, Bay, Victoria, Sta. Cruz, Lumban, Pangil, Calamba, and Siniloan while inland municipalities included Nagcarlan, Rizal, Calauan, San Pablo, and Cavinti.

According to the survey, 65% of smallholder, and 67% of commercial farms admitted to burying veterinary wastes and animal carcasses.

“Buried waste upon decomposition breaks into harmful pollutants which could devoid the soil of nutrients necessary to support life, " Dr. Maria Victoria Espaldon said, one of the authors of the study, and the Dean of the UPLB’S SESAM.

The inaccessibility of incineration, a technology capable of reducing waste by 80 to 90% has led a number of backyard farmers to open-air trash burning.

“This practice endangers the public because of the particulate matter from biomass, and hazardous compounds released from open-burning of plastics and refuse," Espaldon explained.

“It’s important that we limit the possibility of unearthing the carcass, flies and maggots feeding on it, and spreading diseases to both humans and animals," Espaldon added. — TJD, GMA News

to professor, i want to thank you for your efforts in helping our town in educating and informing us to the current situation of our lake, earlier, i thought your bias and let yourself used for political grandstanding. My bad, i apologized, your concern is legit and the info your giving us is worthed and giving us the hope that someday the lake will be cleaned. Some of the information though is so discouraging that the govt. agency(alphabet soup) seems to be far apart that they cant get their things together to get the lake cleaned. Even to the national level, the big boys, they keep dallying with their song and dance which leave the clean up so near, yet so far away. the way things are goin now, it does'nt look the lake will get clean, just hope that our local project will not fall to the same faith. Hopefully, the aquino govt. act faster to see the dire needs to cleaned up the lake. The only thing they all agreed upon is the lake is dying and it needs to get clean.

Rey Bagalso:

I proposed to Ka Noel to look into constructed wetlands to address
Paete's sewage problem back in 2007:

Ka Noel acted on this immediately and sought assistance from the
scientists at UPLB. And the UPLB people headed by Dean Espaldon
(mentioned in the news in the previous post) started working on
developing a proposal for this project. A meeting was held in
June 2008 which I was able to attend.

The national government needs the correct input and data to
decide how to address the pressing needs of Laguna de Bay
and the towns that share the shores and watershed of the
lake. It is unfortunate that science is not given a voice in the
Philippines. The problems that the country will face in the future
require careful studies and good data. The news above show
some hope as it indicates that the new LLDA manager recognizes
the importance of data collection. But the task is still huge, LLDA
is just one small agency.

That is why it is important that Paete, like the rest of the towns
that share Laguna de Bay, needs to step up and show the way.
The solutions to the problems Laguna de Bay is facing must come
from the people with the assistance of competent scientists and
engineers. This is the main problem with the current master plan,
which seems to me, was envisioned purely by entrepreneurs who
got carried away by wild dreams.

The subprojects of Paete, which are endorsed by the World Bank,
will provide the direction that the national government hopefully
will pay attention to. And I hope Paete does take these
subprojects seriously. Data and results can speak volume and
with a national government that seems to lack direction, it is the
only hope.

Yes, these go beyond politics.



Below is posted recently on the Catholic's Bishop Conference
of the Philippines (CBCP) Media Office:

Don’t pay Belgian dredging firm, P-Noy told
MANILA, Sept. 27, 2011—Militant fisherfolk group, Pambansang Lakas ng Kilusang Mamamalakaya ng Pilipinas (Pamalakaya), urged the Benigno C. Aquino III government not to pay the Belgian firm hired to do the dredging of the 90,000-hectare (222,394.843 acres) Laguna Lake in Luzon.

In a statement, Fernando Hicap, national chairperson of Pamalakaya and Pedro Gonzalez, spokesperson of the Save the Laguna Lake Movement (SLLM) said that President Aquino should stand firm for the nation’s interest and decide not to pay, even a single cent to the Baggerwerken Decloedt en Zoon (BDC), the company contracted to do the dredging at the lake, even it has filed a case before the International Centre for Settlement of Investment Disputes (ICSID), in Washington, D.C.

The BDC had decided to file a case against the Philippine Government as a protest against the latter’s decision to cancel the project as it was hounded with controversy. The BDC supposedly is to shell out around P18.7 billion (US$431,370,573.60) in order to “rehabilitate” the lake and to repair its waterways in order to prevent flooding on the places surrounding the lake.

“Instead of relying mainly on the irregularity of the contract as its defense, President Aquino should cite the negative and catastrophic impact of Laguna Lake Dredging project to the livelihood of hundreds of thousands of fisherfolk in Laguna Lake and [the] grand massacre of Laguna Lake environment due to dredging as the principal reasons why the contract is revoked and the project is cancelled,” the two fisherfolk leaders said in a joint statement.

“It would be a grand massacre of people’s sovereignty if Mr. Aquino will insist to pay the P4 billion damage sought by BDC. Why not let former President Gloria Macapagal-Arroyo and her partners-in-crime face the Belgian firm before the international arbitration court and pay the P4-B damage instead? Anyway she has plundered this country twice, thrice or even tenfold of what BDC is asking for as damage,” they added.

But Hicap and Gonzalez doubt if the bachelor president could do it.

“However, the trouble with the Aquino administration is that it cannot assert the collective interest of the Filipino people and it heavily relies on the narrow legal parameters provided by obligations and contract along the game plan of corporate interests,” they said.

The two leaders cite the pushing of the public-private partnerships (PPPs) by the Aquino administration as a means to fund its social and infrastructure projects. For the Gonzalez and Hicap, PPPs mean more debts to pay by the Filipino people while getting less services from the Government.

Meanwhile, the SLLM and the Pamakalaya scored the “alternative” project proposed for the rehab of one of the world’s largest freshwater lakes.

Based on reports received by CBCPNews, there are about 54 projects waiting to be implemented for the lake’s development. One of these is the erection of the 100-kilometer road dike from Taytay, Rizal to the last town of Laguna province which is encompassed by the 94,000 hectare lake.

According to Pamalakaya and the SLLM, the Palace is ready to shell out about P400 billion ($9,227,220,624.67) to fund the said projects. However, the groups fear that it would be a source of corruption as they were sure that there were government officials who would take advantage of the project.

Hicap and Gonzalez also said that they are sure the agencies tasked to implement the project will give the contracts to the “favored” private construction firms. Through this, the commissions and other perks are assured, they said.

Moreover, Pamalakaya said the 54 projects in Laguna Lake under PPP and Laguna Lake Master Plan will displace at least 3.9 million fisherfolk and lake residents. The group said the government intends to reclaim not less than 5,000 hectares of the foreshore area of Laguna Lake to host industrial and commercial hubs to be constructed along the lake.

The group told CBCPNews that the Laguna Lake Development Authority (LLDA), in a dialogue, had admitted it is facing difficulty on how and where to relocate 400,000 families or roughly 2 million people who will be immediately affected as the master plan goes on full blast.

By: Marvyn Benaning

A study undertaken at the behest of the United Nations (UN) has shown that Laguna de Bay is the throes of death unless the Philippine government and the global community do something to arrest its tragic fate.

The Millennium Ecosystem Assessment of the lake was done In 2005 as a means to convince decision-makers to work in earnest to prevent the 94,900-hectare lake into becoming a murky inland water body.

It was undertaken I response to the call made by former UN Secretary General Kofi Annan In June 2001 for nations to comply with the provisions of the Convention of Biological Diversity, Ramsar Convention to Combat Desertification.

The assessment was also linked to the UN Millennium Development Goals and the Plan of Implementation of the 2002 World Summit on Sustainable Development.
A panel of 25 scientist and expert with background on the natural and social sciences and coming from several research and development institutions in the Philippines undertook the study.

Laguna de Bay has 22 major river tributaries or basins even as the Laguna Lake Development Authority (LLDA) list 24.

The Pagsanjan-Lumban Rivers contributes 15 percent of the surface recharge, followed by Sta. Cruz River with 15 percent and the rest with 50 percent.
“Seven major rivers are regularly monitored for water quality, namely Pagsanjan-Lumban, San Cristobal, San Juan, San Pedro, Sta. Cruz, Bay, and Tunasan Rivers.
Rivers in the western side of the lake are heavily polluted with industrial effluents and other wastes.
Based on dissolved oxygen (DO) and BOD levels, most these rivers are virtually dead such as San Pedro, Tunasan, San Cristobal, and San Juan rivers with DO and BOD levels below Class C standards.

Tanay River is deteriorating as indicated by the increasing turbidity, BOD, COD, conductivity, chloride, total phosphorous, and ammonia-nitrogen loads. The problem concerning BOD is most pronounced In river,” the study noted.

The second major finding was that the “major sources if pollution of the river systems are domestic wastes both solid and liquid effluents, food processing plant wastes, livestock wastes, chemical manufacturing spillage, various industrial effluents, fertilizers, and pesticides from agricultural runoff, and eroded soils from the watersheds.
By volume, the domestic sector contributes 68.5 percent; industry 19 percent; ad agriculture,11.5 percent”

Worse, the total coliform counts in all the river feeding into the lake are more than what global standards allow.
Like the highly polluted tributary rivers that were monitored, Laguna de Bay also suffers from a high bacterial count, which poses a constant health hazard to the people depending on the lake resources.

However, the cleansing effect of increased salinity during saltwater intrusion in the summer months somehow arrests the increase in coliform count.
Water quality in the lake made a turn for the worse from 1990 to 1999, when construction activities and upsurge in inland fisheries caused more pollution and aggravated the deposition of sediments on the lake bottom, which is now only 2.5 meters deep on the average and only seven meters at its deepest point.
Based on their mean levels and trends during the decade 1990-1999, many water quality parameters have already exceeded or fallen below the criteria for Class C waters, indicating the worsening condition of the lake.
In terms of biological activity, the lake has become hostile to endemic species and “the biological productivity if this resource has considerably declined. The levels of net primary productivity observed before the 1990s are now hardly met. Even as the lake is still nutritionally within the eutrophic category, its responsiveness to the extant fertility has declined.

“This means that nutrients are not the factor limiting the ability of algae to photosynthesize in the lake. Rather, this could be another factor, most likely, the sufficiency of light.”

PIA Press Release
Wednesday, September 28, 2011
Tagalog news: Kalinisan ng tubig ng lawa ng Laguna, pinagtuunan ng pansin
ni: Alan C. Ortillano

STA. CRUZ, Laguna, Setyembre 28 (PIA) -- Isang consultation meeting ang ipinatawag kamakailan ni Kinatawan Edgar S. San Luis ng ika-apat na Distrito ng lalawigan, upang dinggin ang mga hinaing ng mga mangingisda mula sa mga bayan ng Santa Cruz, Pakil, Paete, Kalayaan, at Lumban kaugnay sa hindi masaganang huli ng mga ito sa Lawa ng Laguna.

Ayon sa mga mangingisda, maaaring ang panapanahong pagpapakawala ng tubig mula sa dam ng Caliraya, na tumutustos sa Caliraya-Bacnotan-Kalayaan Hydro-Electric Plant, ang isa mga dahilan.

Kaugnay nito, tiniyak ni Dr. Isidro Mercado, provincial environment and natural resources officer (PENRO) ng Department of Environment and Natural Resources (DENR), para sa Lalawigan ng Laguna, na ang tubig na pinakakawalan mula sa CBK Hydro-Electric Plant ay nakatutugon sa pamantayang itinatakda ng DENR sa dahilang ang CBK ay may environment compliance certificate (ECC), at ang tubig mula sa kanilang planta ay patuloy na mino-monitor at sinusuri upang matiyak na ang taglay na kontaminasyon nito ay hindi makakaapekto sa industriya ng pagpapalaisdaan na umiiral sa Laguna de Bay.

Tinalakay rin ang posibilidad na ang polusyong nakakaapekto sa kalidad ng tubig sa lawa ay ang residue ng mga agricultural chemical na ginagamit ng mga magsasaka, mula sa pataba hanggang sa pestesidyo o pamatay ng damo at kulisap, at ang obserbasyon ng mga siyentista na ang malaking bahagi ng nakakalasong likido na lumahok sa tubig sa lawa ay ang mga pinaghugasan sa mga tahanan o domestic waste, na higit na mataas ang porsyento kaysa sa liquid waste na mula sa mga pabrika sa kapaligiran ng lawa.

Magugunita na si San Luis ay kagawad ng 15 komite sa Kongreso na ang nakararami rito ay pawang nagtutuon ng pansin sa pangangalaga sa kalinisan at pagpapaunlad ng kapaligiran, kung kaya’t ang suliranin ng mga mangingisda sa lawa ay sa kanya inihihingi ng tulong para magkaroon ng kalutasan.

Dumalo sa naturang pulong sina Mayor Teodoro Adao Jr. ng Kalayaan, Mayor Wilfredo Paraiso ng Lumban, Mayor Domingo “Dennis” Panganiban ng Santa Cruz, Mayor Vipops Charles Martinez ng Pakil, Mayor Emmanuel Cadayona ng Paete, at dating LLDA General Manager Rodrigo Cabrera bilang kasangguni.

Tunay na wala kang makikita o mababasa na pag-aaral na
isinagawa ukol sa masamang epekto ng "hydroelectric plant"
sa Laguna de Bay.

Ang paggamit ng "herbicide" upang patayin ang mga "water
hyacinth" na nakalutang sa Laguna de Bay ay hindi mainam
na paraan kung ang dahilan ay ang mga "water hyacinth" ay
nagiging malaking sagabal sa pagdaloy ng tubig. Hindi kaagad
agad namamatay ang "water hyacinth". Kung kayat ang
pamamaraang ginagamit ay "manual" o "mechanical". Heto
na rin ang isinasagawa ng karamihan ng mga sanga ng
pamahalaan tulad ng LLDA. Heto ang mga balitang iyong
mababasa. Gumagamit sila ng mga bangka na may nakakabit
na "backhoe".

Ang paggamit ng "chemical" sa pagpuksa ng "water hyacinth"
ay matagal ng alam na hindi epektibo at magastos. Heto ay
suliranin hindi lang sa Pilipinas kungdi sa ibang bansa.

Ang mga pag-aaral na isinagawa ukol sa mga suliraning
hinaharap ng Laguna de Bay ay hindi lamang nanggaling
sa pamahalaan ng Pilipinas kundi mula na rin sa mga
iba't ibang ahensya ng Australia, Japan, Netherlands at
World Bank. At marami na rin ang pag-aaral na isinagawa
ng mga "scientists" sa UPLB. Hindi tama na pagbintangan
na lahat ng mga ito ay nabayaran upang itago ang dahilan
kung bakit naghihingalo ang Laguna de Bay.

Napakahirap bang unawain na ang mga taong naninirahan
sa baybay ng Laguna de Bay ang siyang pangunahing dahilan
kung bakit madumi ang Laguna de Bay? Walang "wastewater
treatment facility" ang karamihan ng mga bayan sa Laguna
at Rizal. Ang poso negro ay hindi nakakatulong dahil ang
naaalis nito ay iyong mga "solids" lamang. Ang katas na
nanggaling sa bawat poso negro ay tuloy pa rin ang
pagpunta sa lawa. Milyong-milyon ang nakatira malapit
sa Laguna de Bay. Oo nga at may mga pag-aaral na
nag-uulat na karamihan ng dumi sa lawa ay galing sa mga
tahanan. Subalit kung tutuusin, hindi na kailangan ang
pag-aaral upang marating itong konklusyon. Bilangin na
lamang ang mga tao at isipin kung gaano karami ang dumi
ng bawat isa.

Kung ito ay hindi pa ring maliwanag ay walang magagawa ang
ano mang pag-aaral. Kung ang lumulutang na dumi ng tao
ay hindi sapat upang maunawaan ang kasalukuyang
kalagayan ng Laguna de Bay, walang "malinaw na
research or study".


On a different note, the following shows how cleaning a
river leads immediately to fingerlings of tilapia and biya

It was also a surprising observation that after the system was
put up, hundreds of fingerlings begun to proliferate out in the
cleansed area of the creek—life science in action. It was “fish
galore,” as Dr. Zafaralla had put it. The fingerlings were Tilapia
and Biya.

Kaya kung wala pala namang malinaw na basehan ay wag na sabihin na yon ang dahilan para lang pagtakpan ang tunay na dahilan...

Dahil kahit WB, UPLB. o anumang agencies ay may mga nagawa din silang pag-aaral at sistema na pumalpak...

At madalas pa nga ay ginagawa nila itong TRIALS pero kung sila ay magkamali ay...

Kung sakaling hindi pa malinaw sa iba kung gaano ang
duming nanggagaling sa Paete patungo sa lawa, at
kung gaano ito kung ihahambing sa iba, heto ang
kailangang bigyang pansin:

Una, ang sumusunod ay mapa ng lawa at makikita rito
ang mga lugar kung saan buwan-buwan pinag-aaralan
ng LLDA kung gaano karumi ang tubig:

Ang ilog sa Paete at ang mga bambang ay hindi kasama sa
mga lugar na sinusubaybayan ng LLDA. Ang pinakamalapit
na lugar ay Panguil river - Ang Panguil river ay kasalukuyang
class D. Ano ang kahulugan ng "class"?

Ayon sa Biological Oxygen Demand (BOD5)

class ******* BOD
A at B ******* less than 5 mg/l
C ******* 5 - 10 mg/l
D ******* 10 - 15 mg/l
worse than D *** 15 mg/l

Ano ang BOD or "Biological Oxygen Demand"?

Heto ang kabuuang nagamit na oxygen ng mikrobyo sa loob
ng limang araw. Nangangahulugan na kapag mataas ito, marami
ring mikrobyo sa tubig. Upang mabuhay ang isda sa tubig,
kinakailangan na mayroong oxygen (at least 5 mg/l), kung
marami ang mikrobyo, makikita na sa class C pa lamang, sa
loob ng limang araw, mauubos na ng mikrobyo ang oxygen kung
hindi ito mapapalitan ng sariwang hangin. Ang class C ay maari
pa ring bumuhay sa isda dahil ang "oxygen" na inuubos ng
mikrobyo ay kayang palitan ng sariwang hangin subalit ang
class D ay labis na at mahirap na sa mga isda.

Ano ang resulta ng pag-aaral ukol sa ilog ng Paete at mga bambang?

Sa ginawang pag-aaral ng UPLB (2008-2009), ang mga
bambang ay may BOD na 20-50 mg/l. Ito ay mas masahol
sa class D.

Sa ginawang pag-aaral ng World Bank (ito ay makikita sa ang sumusunod
ay ukol sa Paete:

slaughterhouse BOD = 325
public market BOD = 120
outfall #6 BOD = 120

Ihambing natin muli ito sa mga iba't ibang class ng tubig:

class ******* BOD
A at B ******* less than 5 mg/l
C ******* 5 - 10 mg/l
D ******* 10 - 15 mg/l
worse than D *** 15 mg/l

Ang tubig na nanggagaling sa Paete ay class Z!
Dahil sa taas ng BOD ay lumikha na ako ng bagong class!

Malinaw ang pag-aaral, malinaw ang basehan.

Oo nga at maliit lamang ang ilog ng Paete at ang mga bambang
subalit ang BOD naman nito ay tunay na napakatapang -
halos "raw sewage" at "black water". Ito naman ay hindi
nakakagulat dahil nga walang sewage treatment ang Paete.
Dalawampung libong tao ang dumurumi sa bayan ng Paete at
lahat ng ito sa lawa ang punta.

Dalawang ilog lamang na patungo sa lawa ang class C:
Ang Marikina river at Sapang Baho.

Lahat ng mga ilog patungo sa lawa ay kasalukuyang may
BOD na mas masahol sa class C.

Dito makikita nang napakalinaw kung bakit ang pinakamalaking
bahagya ng dumi sa Lawa ng Laguna ay nanggagaling sa
mga kabahayan.

Mga 1970's, kalakasan ng Ukit dito sa atin, mas marami pa sa 24T ang tao dito dahil sa dami ng dayuhan.

Umalis na lng sila at kaya nabawasan ang populasyon dito sa atin ng humina na ang UKit.

Sigurado ako ng wala pang 10% ang may poso negro noon at halos lahat ng kasilyas ay diretso sa bambang...

Kahit ganon, marami pa ding pauton at iba pang isda na nahuhuli sa bambbang...

Tanungin nyo ang mga mangingisda, at nakita ko mismo noon, karamihan sa kanila ay walang dalang tubig...

Iniinom nila ang tubig galing mismo sa lawa

Ang ibig lng sabihin...

Kahit may dumi ng tao ng diretsong pumupunta sa lawa noon, ay hindi yoon ang dahilan ng pagiging polluted ng lawa na sinasabi sa kung ano-anong pag-aaral na ginawa ng mga dalubhasa (KUNO)

Ano ang BOD ng "sewage"?

"Most pristine rivers will have a 5-day carbonaceous BOD below 1
mg/L. Moderately polluted rivers may have a BOD value in the
range of 2 to 8 mg/L. Municipal sewage that is efficiently treated
by a three-stage process would have a value of about 20 mg/L or
less. Untreated sewage varies, but averages around 600 mg/L in
Europe and as low as 200 mg/L in the U.S., or where there is
severe groundwater or surface water Infiltration/Inflow. (The
generally lower values in the U.S. derive from the much greater
water use per capita than in other parts of the world.)"

-Clair N. Sawyer, Perry L. McCarty, Gene F. Parkin (2003).
Chemistry for Environmental Engineering and Science (5th ed.).
New York: McGraw-Hill. ISBN 0-07-248066-1.

Mas mababa ang BOD ng sewage sa Amerika dahil ang dumi ay
nahahaluan ng mas maraming tubig.

Ang Paete ngayon ay may sariling tubig na maaaring gamiting
inumin. Sinasabing 2000 cubic meter bawat araw ang dumadaloy
rito. Ang malinis na tubig na ito ay nanggagaling sa mga natural
na bukal ng Paete. Noong una, ang malinis na tubig ay kusang
dumadaloy mula sa bundok patungo sa mga bambang. Mula sa
pag-aaral ng World Bank, ang outfall 6 ay may flow rate na 536
cubic meter bawat araw. Makikita na kung sa halip na sa gripo
ng mga bahay pumunta ang 2000 cubic meter na malinis na
tubig ay sa bambang umuwi, ang BOD ng bambang ay bababa
ng mahigit na limang ulit (mula sa 120 pababa patungo sa 24 -
magiging malapit na sa class D).

Ang kabundukan na nagbibigay ng malinis na tubig ay hindi rin
nasa magandang katayuan. Marami nang na walang puno kayat
ang tubig na nanggagaling sa ulan ay hindi na naiipon at kaagad
agad nang dumadaloy patungo sa lawa. Dahil dito , hindi na rin
tuluyang nababawasan ang BOD ng mga bangbang dahil kung
umulan man, ang malinis na tubig ay daglian ding dumaraan at
mabilis na umaagos patungo sa lawa. Noong unang panahon,
ang tubig na nanggagaling sa bundok ay naiipon at marahang
umaagos sa ilalim ng lupa at patuloy na nilalabnaw ang mga
maruming tubig sa bambang.

Kayat hindi kamanghamangha kung bakit tila mas malala ang
dumi ngayon sa Paete. Una, ang malinis na tubig ay nahiwalay
ng mga isinagawang water works ng bayan ng Paete. Pangalawa,
ang kawalan ng mga puno sa kabundukan ay nagbawas sa
malinis na tubig na kusa at mahinay na dumadaloy mula sa
kabundukan patungo sa bayan.

Ang dumi na nagmumula sa lawa at sa ibang bayan ay
mahihirapang pumasok sa mga bambang ng Paete. Ang
natural na daloy ng tubig ay mula sa bambang patungo sa
lawa. Kaya kung walang isda sa mga bambang, hindi ito
dulot ng mga pabrika o hydroelectric plant kundi dulot ito
ng maruming tubig na nanggagaling mismo sa mga kabahayan ng

Karagdagan, hindi madaling gamitin ang panahon sa pag-aaral
ng kasalukuyang kalagayan ng lawa ng Laguna. May magsasabing
ganito na rin naman ang kalagayan noong 1960 - walang mga
poso negro, sa bambang lahat itinatapon - at bakit hindi malaking
suliranin ang dumi sa lawa ng Laguna noon.

Ang tugon dito ay ang "eutrophication" ng isang lawa ay
mahabang "process". Ang likas na pagbabago ng isang lawa
ay inaabot ng daang daang taon. Samantala, kung ang dumi ng
tao ang magbabago sa isang lawa, ang "eutrophication" ay
maaaring mangyari sa loob ng ilang sampung taon. Kung kayat
pag tiningnan ang kasalukuyang kalagayan ng lawa ng Laguna,
maliwanag na ang kaniyang "eutrophication" ay mabilis (hindi
na kailangang ang ilang daan taon bago masaksihan ang pag-
kamatay ng mga isda rito). Nangyayari na sa iba't ibang dako
ng lawa ang biglaang pagkamatay ng mga isda. 2011 ay
limampung taon lamang mula sa 1960 kaya maliwanag na ang
"eutrophication" ng lawa ng Laguna ay gawa ng tao o "anthro-

Ang isa pang dulot ng polusyon sa lawa ng Laguna
ay "genotoxicity". Ito ay nangangahulugan na ang epekto ay
hindi nakikita sa kasalukuyang isda ngunit sa magiging supling
ng mga ito dahil ang nasisira ng polusyon ay ang DNA ng mga isda.
Ang epektong ito ay nakikita lamang sa pagdaraan ng ilang
henerasyon ng isda. Kamakailan lamang nabanggit dito sa
Usap na may mga lalaking isda na lumaki sa tubig na malapit
sa Paete na mayroong mga organs na pambabae lamang.

Monday, 10 October 2011 05:17 | Last Updated on Monday, 10 October 2011 07:16 | Written by Calamba Super Administrator | |

Calauan Laguna--- Inihayag ng bagong General Manager ng Laguna Lake Development Authority at Presidential Adviser for Environmental Protection na si Secretary Nereus Acosta sa kanilang ginanap na dialogo kanina sa (Oct 10) sa pagitan ng mga environmental NGO, representatives ng green convergence, at representatives mula sa Bay, Calauan river rehabilitation and protection council na panahon na upang magkaroon pagbabago at rehabilitasyon sa lawa ng Laguna.

Binigyang diin nito na mayroon siyang mandato mula kay Pangulong Noynoy Aquino na magkaroon ng transpormasyon sa Laguna de Bay tulad na lamang ng paglilimita sa mga naglalakihan at nagdadamihang mga fish cages, pagpapasara sa mga pabrika na nagdudulot ng polusyon sa tubig ng lawa, paglilinis sa mga basura at pagpapalipat sa ibang tahanan ng mga settlers.

Dagdag pa ng kalihim prayoridad nito na makabili ng mga makabagong kagamitan na magagamit sa pagsusuri sa kondisyon at tubig ng lawa, matatandaang pinagaaralan na ng ahensiya kung posible bang magamit ang tubig ng lawa sa pangangailangan ng mga milyong residente sa National Capital Region.

“...Alangan namang mag-enforce ka wala ka namang basehan, so kung hindi matibay at mas upgraded ang mga equipment sa mga laboratory sa water analysis mo d'un sa mga tinatawag na automated telemetric kahit malayo makikita mo 'yung resulta at 'yung datos” ani Acosta.

Bukod dito sinabi pa ni Secretary Neri ang plano nilang makapagpatayo ng sariling establisimyento na tatawagin nilang green building, aniya mahirap mag-umpisa ng isang institusyon kung wala kang tiyak na tahanan at palipat lipat lang. Inihayag din niya na nakipagusap na siya kay Budget and Management Secretary Florencio Abad tungkol sa inisyal na pondong kailangan niya sa pagbili ng mga makabagong kagamitan at sa pagpapatayo ng kanilang building na nagkakahalaga ng isang daang milyong piso.

“...Humingi agad tayo kay Secretary Abad 'yun nga upgrading sa science una yan eh yun ang priority tapos yung pangalawa dahil wala pang sariling opisina ang LLDA umuupa lang kami hanggang ngyon, paano magiging matibay ang institusyon mo kung palipat lipat”

Kompiyansa siya na bago matapos ang taong ito ay maaaprubahan ang nasabing halaga ng pangulo. Samantala nilinaw din ng kalihim kanina sa LLDA Complex na hindi pabor ang pangulong aquino sa panukalang paghuhukay o dredging sa lawa lalo nat gugugulan ito ng hindi birong halaga- CJ ALCANTARA

Tagalog news: Muling pagsigla ng bundok Banahaw at San Cristobal, nababanaag na
SAN PABLO CITY, Laguna, Nobyembre 22 (PIA) --

Tuloy-tuloy ng napapaunlad at napaghihilom ang mga kasiraang naidulot ng pag-abuso ng tao sa mga bundok ng Banahaw at San Cristobal dahil na rin sa mga karagdagan at mga tiyak na kapangyarihang pinapairal ng Protected Area Management Barod (PAMB) para mapangalagaan ang kapaligiran ng dalawang bundok.

Sa ulat ni Park Supervisor Salud Pangan ng Mount Banahaw Protected Area, bunga ng isinagawang pagbabawal na ang bundok ay pasukin ng mga taong walang kaugnayan sa pangangasiwa sa kapaligiran nito, maraming uri ng halaman ang muling nakikita, at maging ang mga sapa, tulad ng Kristalino, Suplina, at Salaming-Bubog na halos ay natuyo na ay muling dinadaluyan ng masaganang malinis na tubig.

Batay din sa ulat ng Department of Environment of Natural Resources (DENR) IV-A na maging ang mga katutubong hayop dito na noong taon 2007-2009 ay bihira ng makita ay unti-unti nang naggagala sa lawak na dati nitong pinananahanan, dahil sa maigting na kampanya sa kautusan para mapangalagaan ang kapaligiran at kalikasan ng dalawang kabundukan nabanggit na naaayon sa batas.

Sa mga estadistika, napag-alaman naang dalawang kabundukan ay tinatayang may kabuuang lawak na aabot sa 22,000 ektarya na nahahati sa mga lalawigan ng Laguna at Quezon. Batay sa kanilang pinaniniwalaang may nabubuhay na halos 600 iba't-ibang uri ng hayop, kasama na ang mga ibon, at halos ay 60 halaman o plant species, na ang marami ay dito lamang matatagpuan.

Ang kapaligiran ng dalawang bundok ay isang malawak at matatag na wateshed na napagkukunan ng inuming tubig para sa may isang milyong mamamayan sa paligid nito, at nagpapakilos ng isang hydroelectric plant na nakatayo sa sakop ng Laguna.

Sa pagiging matatag ng kakahuyan sa kapaligiran ng dalawang bundok, ito ay nakatutulong upang ang tubig na umaagos mula rito pababa sa Laguna de Bay o sa Tayabas Bay ay mayaman sa "humus" at nagpapasigla sa industriya ng pangisdaan sa Katimugang Tagalog.

Natural filtration for Laguna de Bay eyed
By Maricar Cinco
Inquirer Southern Luzon
3:02 am | Sunday, November 27th, 2011

It was a laid-back rural scene worthy of a painting by Fernando Amorsolo: women chattering over their laundry and their children doing stunts and splashing in the shallow Molawin Creek.

But for University of the Philippines Los Baños (UPLB) environmental scientist and phycologist Macrina Zafaralla it was an upsetting scene. Her eyes had focused on one of the boys, who filled his mouth with water and gulped it down.

“Not a kilometer away (from these people) was a sewerage outfall,” said Zafaralla, aghast.

Disturbed by what she had witnessed and the dangers to the health of the children, Zafaralla in March 2009 embarked on “phytoremediation,” a process of using plants to filter the water flowing down a 7-kilometer stretch of the Molawin Creek in Los Baños, Laguna.

Molawin Creek is one of the 33 tributaries and rivers of the Laguna Lake. It carries all forms of wastes from Mt. Makiling, the university facilities, dormitories, piggeries, and residential communities all the way down the stream.

Polluted lake

To reduce the solid waste pollution in the creek, Zafaralla installed a structure of interlocked bamboo poles across the five-meter width of the creek. She then let grow a meter-breadth of water hyacinths, which she calls the Aquatic Macrophyte Biosorption System (AMBS).

The water hyacinths soak in the water and absorb the wastes, thus filtering the water that flows to the other side of the structure.

Basically it’s “a barricade that functions as a living filtering system,” she said.

Zafaralla introduced the AMBS at a forum of lake fishers organized by Kilusang Lawa Kalikasan (KLK) at the compound of the Laguna Lake Development Authority (LLDA) here on Nov. 19.

KLK is a nongovernment organization of fishermen that aims to improve the condition of the deteriorating inland body.

“No one will deny that the lake is polluted. But to what extent is it polluted? Is the fish still safe to eat? There is a need to look (into these),” said Deputy House Speaker and Quezon Rep. Lorenzo “Erin” Tañada III, who was the guest speaker at the forum.

Tañada has filed a Laguna Lake Conservation Authority Act in Congress.

The KLK tapped the science community to replicate the AMBS in other lake tributaries.

Fish galore

Based on Zafaralla’s findings, the AMBS was able to collect tons of solid wastes. The water, after passing through the system, became clearer. She noted that aquatic life was also restored.

“Before, it was very hard to find a single fish in the (Molawin Creek). But in two to three weeks’ time (after the AMBS was placed), we noticed that tilapia fingerlings grew abundant. It was ‘fish galore.’ The fish were as many as the raindrops from the sky!” Zafaralla gushed.

Village caretakers

Zafaralla first tested the AMBS on the Molawin Creek near a community of about 45 families in Sitio Riverside.

“There was really no fish before. If there were a few, people would scoop out even the fingerlings just to have food,” said resident Mario Macan, 28. With no other options, the men worked as garbage collectors and the women as vegetable and flower vendors.

Pleased to see the return of a food source due to the AMBS, the residents themselves volunteered to collect the garbage trapped in the water hyacinth filter.

Zafaralla also taught them to prune the hyacinths so they would not grow into a thicket that would clog the water flow, and to dredge the riverbed to prevent its “shallowing” due to the accumulated sediments.

Whenever the water rises or flash floods destroy the bamboo structures, residents know how to fix and put them back.

“Almost every day, someone checks the river and picks up the thrash. We now have an everyday supply of fish for our families,” said Macan.

New biopark

The UPLB in 2010 declared the Molawin Creek a biopark. The university is the caretaker of the tributary.

A foreign research institution recently pledged support to Zafaralla’s study on the creek’s water quality.

Zafaralla said the next part of her research will focus on the biological and chemical quality of the water filtered by the AMBS. The research will also find out whether the system can also trap toxic and non-solid wastes such as lead and oil.

LLDA promotes green solutions for domestic wastewater problem
TAYTAY, Rizal, Nov. 29 (PIA) --

Since 2010, the Laguna Lake Development Authority (LLDA) has been aggressively promoting the use of “constructed wetlands” to control the growing problem on domestic wastewater coming from the 14 million inhabitants living in the Laguna de Bay Region.

LLDA introduced the concept of natural wastewater treatment systems through a partnership with the USAID Environmental Cooperation-Asia (ECO-Asia) in collaboration with Chia Nan University of Taiwan (CNU) and Calamba Water District as means to solve the growing wastewater problem in the region at the least cost but most effective and efficient way.

Constructed wetlands (CWs) are artificial wetlands designed to intercept and remove a range of pollutants from wastewater. The pollutants retained in CWs are stabilized through solar energy, gravity and ecological action of microbes and macrophytes.

Today, most industries and local government units (LGUs) in the Laguna de Bay Region still lack basic wastewater treatment infrastructure due to lack of funding and technical know-how.

Hence, LLDA is now promoting the use of CWs due to its easy construction, low maintenance cost, and very low energy consumption. Aside from its natural treatment capacity, CWs also offer multiple uses such as wildlife habitat, landscape, aesthetic, recreation and education.

The municipalities of Angono, Rizal and Lucban, Quezon as well as the City of Calamba, Laguna will be among the firsts in the Laguna de Bay Region to develop a wastewater treatment facility using natural systems such as constructed wetlands to serve community residents within their respective jurisdiction.

LLDA works with CNU to disseminate knowledge and best practices on low-cost natural treatment systems. This is financed by the World Bank through the Laguna de Bay Institutional Strengthening and Community Participation (LISCOP) Project. On capacity-building and training, LLDA works with CNU and BNS-BORDA.

For the succeeding years, LLDA will expand the partnership and promote the replication of innovations and good practices introduced in Calamba, Angono and Lucban to neighboring towns and cities in the entire region. Under the expanded program, LLDA will develop the guidelines and work with LGUs on model ordinances on natural treatment systems. (Martin Christopher B. Antonio, Public Information Specialist, LLDA/CPG, PIA-Calabarzon)

Update on LISCOP (from ka Noel):

Mauuna yong WWTF, we have completed all requirements. The DENR Director just signed the ECC only last week. Bidding is expected within January.

We encountered a hitch on the SLF/MRF. The National Grid Corp.(NGCP) won't give us a permit because it traversed through a small portion of the lot. Their primary concern is any excavation might adversely affect the towers foundation. The foundation is very far from the cell so we will show them the plan and try to convince them that excavation of the cell will be of no consequence. We have a meeting with the manager on Jan. 5.

If memory serves, Mayor Mutuk was vehemently opposed to the WWTF project when it was presented for public hearing at the time that he was the Vice Mayor and Presiding Officer of the SB. I wonder if the project is still pursued by the present administration.
