A.03.b.2.2.2.a Waterbody Classification

Classification of a water body is setting the minimum criteria for a particular water body to be maintained for the next ten (10) to twenty (20) years. As such the present socio-economic and ecological profile as well as the development plan of the local government unit concerned that will have potential impacts to the body of water should be considered during the process of classification.

The targeted waterbody for classification for this CY-2020 are Janagdong-Guisguis River, Mamala-Sariaya River and Talim-Jibanga River all located in Sariaya, Quezon; and Mulanay River located in Mulanay, Quezon. Activities implemented during the first quarter and second quarter include coordination meetings with the concerned Local Government Units (LGU), survey and establishment of water quality sampling stations in each river and conduct of water sampling.

Survey and Establishment of Sampling Stations

In coordination with the LGU of Sariaya on January 14, 2020, the EMB RO personnel conducted reconnaissance survey of the stretch of Janagdong-Guisguis River, Mamala-Sariaya River and Talim-Gibanga River. This is to identify and establish the strategic locations for sampling stations in terms of accessibility and viability. Based from the guidelines for water body classification program, a minimum of three (3) monitoring stations should be established. The established monitoring stations for the target rivers are shown in Tables 1 to 4.

Water Sampling

The supposed twelve (12) months consecutive sampling activity for the classification of a waterbody was affected by the declaration of community quarantine due to the COVID-19 pandemic. On February, water sampling of Janagdong-Guisguis River, Mamala-Sariaya River and Talim-Gibanga River was started but suspended on the month of March. At the Mulanay River, water sampling was started on the month of January but also ended on the February.

During the month of June when General Community Quarantine was declared in the province of Quezon, water sampling at Janagdong-Guisguis, Mamala-Sariaya and Talim-Gibanga Rivers were scheduled on June 18, 2020 while Mulanay River is scheduled on June 26, 2020. Unfortunately, these were cancelled due to confirmed COVID-19 cases in the region.

Results of water quality analyses for the period are shown in the tables below:

Issues and Concern

The declaration of community quarantine due to threat to public health of COVID-19 from March 16, 2020 has halted the conduct of monthly water sampling in the four (4) target water bodies.

A.03.b.2.2.4 ADOPT AN ESTERO/WATERBODY REHABILITATION PROGRAM

The “Adopt”–A-Estero/River Program is a mutual undertaking between and among communities along esteros and rivers, concerned local government units, private sector and the DENR-EMB. This program is a leverage to improve its water quality and achieve a healthier environment through regular cleanup activities such as dredging, collection of floating debris, planting and maintenance of appropriate species, installation of trash traps and engineering design to mitigate soil erosion that cause siltation and turbidity to water bodies.

To date, the Region has forty-six (46) adopted rivers and creeks with support from sixty-two (62) private sector and LGU adopters. List of rivers and donor partners is reflected in Table _____ and Figure _____.

The Water Quality Management Section of the Region conducts quarterly monitoring of adopted rivers and creeks by using two (2) parameters: Dissolve Oxygen (DO) and Biochemical Oxygen Demand (BOD). As per monitoring reports from 2012 to date, the river/creek water qualities of all sixty-two (62) active donor partners have improved fairly. The Section also provides necessary technical assistance to concerned leaders/adopters and stakeholder groups in the area.

For the first half of this year 2020, the implementation of the Program was greatly affected by the Total Luzon Lockdown and the Enhanced Community Quarantine (ECQ). Some of the adopters were not able to conduct their interventions most especially those which are also affected by the eruption of the Taal Volcano. However, it is worthwhile to mention that despite the natural occurrences such as the pandemic and the Taal Volcano eruption, six (6) donor partners were still able to perform their responsibilities. These are the Hardrock Aggregates, Central Azucarera Don Pedro, Inc., Pacific Concrete Products Inc, Primex Coco Products, RFM Corporation and First Cavite Industrial Estate.

A.03.b.2.2.4.1 Accomplishments of Six Donor Partner

Hardrock Aggregates

It has been a regular activity of the company to maintain the cleanliness of their adopted river. On February 20, 2020, Hardrock Aggregates conducted the Kay-bibit River and Road Clean-up with a theme, “Cleaning the River for the Clearer Water” which is also the slogan of the company for their adopted river. A total of 97 kilograms of 17 sacks of solid wastes and/or trash were collected during the clean-up and brought to Antipolo City SLF.

The activity was participated by the representatives of Hardrock Aggregates Inc., LGU Cupang, LGU Mayamot and the sub-contractor volunteers. During this activity, a tarpaulin was installed along the riverbank showing the implementation of the program to the area. Moreover, the regular activities of the Hardrock Aggregates under this program are the following:

Removal of trash/debris from the waterways
Maintenance of trees planted along the riverbanks.
Promotion of environmental awareness, cleanliness and stewardship in the area

Central Azucarera Don Pedro, Inc.

For Central Azucarera Don Pedro, Inc. (CAPDI), they regularly conduct tree planting and river clean-up to their adopted river at Palico-Lian River, in partnership with the residents of Brgy. Lumbangan, Roxas Village. In addition, CADPI together with Brgy. Lumbangan and MENRO of Nasugbu conducted the education training on proper solid waste segregation.

The company also conducted coastal clean-up on March 07, 2020 at Adams Beach Resort, which was participated by the volunteers from Kiwanis Club, Ladies of Charity and Brgy. Lumbangan. A total of 210 kilograms of solid waste was collected during the clean-up and brought to Municipal SLF in Brgy Dayap. Indeed, this initiative also promotes the conservation of waterbodies not only the rivers but also the coastal areas which are at risk of waste pollution.

Moreover, CAPDI established tree nursery as a source of seedlings for planting along the riverbanks of their adopted river. As of March 2020, a total of 521 seedlings comprised of different tree species such as Neem Tree, Sampaloc Tree, Palmera Tree, Acacia Tree and Mahogany Tree has been raised and maintained.

Pacific Concrete Products, Inc.

Parallel to CADPI, Pacific Concrete also conducted tree planting on February 23, 2020 along the riverbanks of Wawa River. This will help in preservation of river against soil erosion especially during heavy flooding as well as protect the residents from flood damages. The trees planted were Narra, Mahogany and Rambutan. PCPI also conducted a clean up to its nearby creek wherein 200 meters were cleaned, and 2 sacks of solid wastes were collected.

Primex Coco Products

The company conducted regular clean-up on their adopted waterbody, Mangilag Creek, every month. An approximate of 75 kilograms or 3 sacks of residual solid wastes were collected during clean-up. The solid wastes collected such as scrap woods and leaves were reused for the boiler while the plastics and other non-biodegradable wastes collected were brought to their MRF. Moreover, the regular activities of the Primex Coco Products under this program are the following:

Tree planting along the riverbanks
Helping the next barangay to clean the river creek (San Andres Creek) twice a year
Providing seminar or IEC campaign about solid waste segregation
Removal of all debris that obstructs the continuous flow of water creek
Continuous improvement of the wastewater treatment plant

Primex Coco Products also experienced struggles while implementing the program. Some residents living in the area have no idea of solid waste segregation which imposes sanitation problems not only to the community itself but also to the adjacent waterbody in the area which is, the Mangilag Creek. For this reason, it is imperative for IEC initiatives to be conducted in the community with active engagement of the LGU, private sectors and other program partners to mitigate/prevent further water quality degradation.

RFM Corporation

Their initiatives include the clean -up drive conducted on May 28, 2020 on their 7-kilometer stretch NIA Creek. The said clean-up stretches from Brgy. Mamatid, Cabuyao up to Brgy. Salang-Langka. The solid wastes were taken care of by Steriplus Corp. and brought to Rodriguez/ Montalban SLF This was in partnership with the Cabuyao City Environmental Police. After the said clean-up, RFM Corp. distributed goods to the Environmental Police of Cabuyao.

First Cavite Industrial Estate

Physical improvements is noticeable in their adopted river, Ylang-Ylang River such as the decrease in the amount of solid wastes found in the river and increased vegetation along the riverbanks. This is also manifested in their BOD and DO result for the first quarter this year which greatly improved and passed the DENR Standards compared to last year’s result.

A.03.b.2.2.4.2 Major Accomplishment in terms of improvements

Water quality

Result of water quality for Dissolved Oxygen and Biochemical Oxygen Demand physico-chemical showed fair improvement in their adopted river.

IEC Campaign

Installed tarpaulin design/billboard at the entry of river stating the importance of proper disposal of solid waste generation, Moreover, other program partners conducted Environmental clean-up and it was celebrated thru tree planting activities in support with the National Greening program of the government and Climate Change initiatives.

Solid Waste Management Program

On the first half of 2020, 702 kilograms of solid wastes were collected as shown in Table ______. However, this does not represent the overall or the totality of wastes collected within the Region because the other adopters have not yet conducted clean up due to the Total Luzon Lockdown and Enhanced Community Quarantine. Nonetheless, these initiatives made by program partners are still significant in obtaining environmental conservation and preservation.

In addition, through continuous Information, Education, Campaign (IEC) and cooperation of concerned community, the awareness of the people on the impact of proper wastes management not only on the environment but also to their health are being realized.

Other activities if any,

Baseline data gathering
Maintenance of riprapping/gabions installation
Maintenance of linear planting
Donation of waste drums
Creation of River Ecological Council
Dredging /De-clogging of canal
Monitoring of water quality
Removal of illegal dumpsite near the adopted river in coordination with the LGU

Decreased mobility for conducting activities due to the implementation of Total Luzon Lockdown and/or Enhanced Community Quarantine.

A.03.b.2.2.4.4 Recommendations

Community participation from the start of planning stage up to monitoring phase and focus on one major river where donors partner is invited to participate;
Continuity of giving exemplary awards to all active adopters for the effort they are doing in cleaning up polluted rivers;
Strengthening public awareness, education and information dissemination especially during this pandemic where special wastes such as face masks and gloves are thrown to the rivers;
To involve small scale piggery operators in adopt a river program;
In coordination with the LGU, there should be implementation of Material Recovery Facility in Barangay level as mandated under the provision of RA 9003 and educate the local resident residing near the river for the proper implementation of solid waste management;
Enhancing River clean up through collective learning and involvement of the community from planning, implementation, evaluation and monitoring of the program activities;
The NSWMC could recommend to the LGU to tap ER1-94 funds for the Environmental Enhancement projects i.e. Establishment of MRF for those power plant and Mining partners;
Sustained efforts are needed to raise public awareness and gain the support of the local communities thru passing an ordinance with the LGUs for the protection of the planted trees in the adopted river; and
Continuous Monitoring and Evaluation to monitor the progress of the program especially the impact of generated waste during this pandemic.

A.03.b.2.2.5 Recreational Waters Monitoring

Recreational water bodies identified in the CALABARZON Region pursuant to MC No. 006 series of 2015 (Guidelines for Recreational Waters Monitoring Program) are within Marine and Coastal Waters specifically along beaches of Laiya, Lemery, Nasugbu and Matabungkay all in the province of Batangas. Priority Recreational Waters are Laiya Beach in the municipality of San Juan and Nasugbu Beach in the municipality of Nasugbu while two other Recreational Water Bodies being monitored are the Lemery Beach in the municipality of Lemery and Matabungkay Beach in the municipality of Lian.

Nasugbu Bay was classified pursuant to DAO 34 as Class SC but the stretch of its beach is being beneficially use for bathing purposes. These are the Nasugbu Beach and Matabungkay Beach. On the other hand, the Balayan Bay adjoining the beach of Lemery and the Tayabas Bay adjoining the beach of Laiya are yet to be classified but are currently being beneficially used for bathing and other recreational activities. Hence, were included under the program pursuant to MC No. 006 series of 2015.

Water quality monitoring of Laiya Beach, Matabungkay Beach and Nasugbu Beach were conducted during the months of January, February and March, 2020 while for Lemery Beach, monitoring was only conducted on the month of February. No water quality monitoring was conducted during the whole second quarter due to the community quarantine relative to COVID-19 pandemic. Monitoring results showed that pH is within the Class SB water in the four (4) bathing beaches. On the other hand, Fecal Coliform is also within the guideline except at Matabungkay beach and Nasugbu Beach during the month of March.

Water Quality Monitoring

Water quality monitoring in the four bathing beaches were conducted during the months of January, February and March, 2020 at the Laiya Beach, Matabungkay Beach and Nasugbu Beach and on the month of February at Lemery Beach. Primary water quality parameters analyzed were Fecal Coliform and pH pursuant to MC No. 006 series of 2015. Results of monitoring are shown in the succeeding tables below:

Fecal Coliform during the month of March exceeded the guideline in all monitoring stations at Matabungkay Beach. Water quality sampling from April to June were suspended due to the implementation of community quarantine because of Covid-19 pandemic.

Issues and Concerns

The eruption of Taal Volcano on January 12, 2020 has deferred the start of monthly water quality monitoring of Lemery Beach and the declaration of community quarantine due to threat to public health of COVID-19 from March 16, 2020 has halted all the monthly water quality monitoring activities.

A.03.b.2.2.5 Monitoring of Priority Rivers and Other Water Bodies

This program is under the regular water quality monitoring activities which primarily aims to determine the trend of water quality improvement and/or deterioration in each water body whether or not this conforms to its baseline data to which this was classified. The results and recommendations herein shall serve as reference for implementation of appropriate management measures whether issuance of specific policy guidelines and/or actions/interventions that would lead to the rehabilitation, protection and preservation of the water quality of such water body.

In 2016, Calumpang River and Pansipit River both located in the province of Batangas were prioritized for monitoring under this program. Calumpang River drains in the municipalities of Rosario, Ibaan, Taysan, San Jose and Cuenca and the cities of Lipa and Batangas with common outlet to Batangas Bay at Batangas City. On the other hand, Pansipit River is the drainage outlet of Taal Lake to Balayan Bay. It stretches for about 9 kilometers passing along the boundaries of towns of San Nicolas and Agoncillo on its upstream and Lemery and Taal at its downstream.

In 2018, Maragondon River, Labac River, Timalan River and Obispo River located all in the province of Cavite were also included for monitoring considering its contribution to the pollution loading of Manila Bay and because of the Writ of Continuing Mandamus of the Supreme Court for the rehabilitation, protection and preservation of Manila Bay. In 2019, Calibuyo River also located in Cavite was added as other waterbody monitored considering also its contribution to the pollution loading of Manila Bay.

All these rivers were classified as Class C water which is intended for: 1) Fishery Water for the propagation and growth of fish and other aquatic resources; 2) Recreational Water Class II for boating, fishing or similar activities, and 3) For agriculture, irrigation, and livestock watering.

Water Quality Monitoring

The water quality monitoring of two (2) priority water bodies, Calumpang River and Pansipit River, both located in the province of Batangas were only conducted in the month of February 2020 during the first quarter while other water bodies being monitored such as Maragondon. Labac, Timalan, Obispo and Calibuyo Rivers in the province of Cavite were conducted in the months of January and February 2020. The declaration of Enhanced Community Quarantine (ECQ) during the second week of March has halted the monthly monitoring activities.

When the classification of ECQ was downgraded to General Community Quarantine (GCQ) in June, the Water Quality Management Section prepared monitoring schedules for the resumption of water quality sampling. Calumpang and Pansipit Rivers were scheduled on June 23, 2020 while Maragondon, Labac, Timalan, Obispo and Calibuyo on June 30, 2020. Unfortunately, one the personnel of this Office contracted COVID-19 virus affecting the operation of the Regional office and the environmental laboratory. For the safety of personnel, the whole Region and the laboratory were lockdown and subjected for disinfection as well as the vehicles used by the office on June 18, 2020. All personnel were subjected to Home quarantine.

Result of laboratory analysis for first Quarter period are shown in the tables below:

Issues and Concern

The eruption of Taal Volcano on January 12, 2020 has deferred the start of conduct of monthly water quality monitoring of Pansipit River and the declaration of community quarantine due to threat to public health of COVID-19 from March 16, 2020 has halted the conduct of monthly water quality monitoring activities in the seven (7) target water bodies.

A.03.b.2.2.6. Water Quality Management Areas

There are three (3) existing Water Quality Management Areas (WQMAs) in CALABARZON Region designated through DENR Administrative Orders. The two (2): Canas-Maalimango Rivers WQMA and Imus- YlangYlang-Rio Grande Rivers WQMA are both located in Cavite province while the Iyam-Dumacaa Rivers WQMA is in Quezon province.

CAÑAS- MAALIMANGO RIVERS WATER QUALITY MANAGEMENT AREA (CMR-WQMA)

The operationalization activities for the Cañas-Maalimango Rivers WQMA implemented during the first and second quarter of 2020 include coordination and provision of technical assistance to WQMA covered LGUs for their adoption of WQMA designation and action plan through Sangguniang Bayan/Panlungsod Resolution, coordination with the Governing Board for the conduct of board meetings via video conference, water quality monitoring activities and other WQMA related activities.

I.1 Background

The Cañas-Maalimango Rivers WQMA with an area of 11,893.31 hectares was designated by virtue of DAO 2016-19. The downstream of Canas River beginning from its mid-section in Trece Martires City to the municipalities of General Trias, Tanza and Rosario was classified as “Class C” pursuant to DAO 34 Series of 1990 which is intended for: 1) Fishery Water for the propagation and growth of fish and other aquatic resources; 2) Recreational Water Class II for boating, fishing or similar activities, and 3) For agriculture, irrigation, and livestock watering. While its upstream from Trece Martires City to the Municipalities of Indang and Amadeo was classified in 2007 as “Class B” which is intended for primary for contact recreation (bathing, swimming, etc.).

On the other hand, Maalimango River is unclassified but it is beneficially being used for fishery by the local people of Rosario, Cavite. Hence, the same can be classified as Class C based on its present beneficial use pursuant to DAO 2016-08.

I.2 Operationalization Activities Implemented

Board Meeting

Pursuant to Section 15.1 of CMR-WQMA Governing Rules, on the conduct of quarterly board meetings, the scheduled first quarter board meeting dated on March 19, 2020 was suspended due to the Enhanced Community Quarantine implemented by the Government. For the updates on the previous agenda, below are the list of Local Government Units with Sangguniang Resolution on the adoption of DAO 2016-19 and Ten-Year Action Plan.

Cañas River

The results of first quarter water quality monitoring of Cañas Rivermouth showed exceedances in Phosphate, Chlorides, TSS and Fecal Coliform count. On the other hand, monitoring at the river also showed exceedances on Phosphate, BOD, TSS and Fecal Coliform in most of the monitoring stations. All other physico-chemical parameters are within the guidelines. During the second quarter, no monitoring activities were implemented in observance of the community quarantine and/or due to the risk of COVID-19.

Maalimango River

The results of water quality monitoring of Maalimango River during the first quarter monitoring period showed exceedance in Phosphate, Chlorides, BOD and TSS for Class C water in the three monitoring stations. Level of DO dropped to as low as 0.7mg/L during the months January to February this may due to the high concentration of BOD in the water. All other physico-chemical parameters are within the guidelines.

For bacteriological analysis, Fecal Coliform has consistently exceeded the guideline in all monitoring stations throughout the monitoring period.

I.3 Issues and Concerns

The declaration of community quarantine due to threat to public health of COVID-19 from March 16, 2020 has halted the conduct of first and second quarter Governing Board meetings, monthly water quality monitoring, coordination meetings with the LGUs and other related activities.

II.2 Water Quality Monitoring

Water quality samplings were conducted monthly during the months of January and February 2020. Samples were brought to the laboratory facility in Kawit, Cavite for analysis of the Ten (10) primary parameters pursuant to DAO 2016-08 “Water Quality Guidelines and General Effluent Standards of 2016”. Water Quality monitoring was suspended during the months of March, April, and May 2020 due to Enhanced Community Quarantine (ECQ) by the Government. On the month of June when the province of Cavite was declared General Community Quarantine (GCQ), water quality monitoring was resumed. Water sampling was conducted at Ylang ylang River and Rio Grande River but due to risk of Covid-19 among the employees, water sampling at Imus River was not conducted.

Results of laboratory analysis are shown in the table below.

Imus River

The monitoring results of Imus River during the months of January and February showed excessive exceedances in Phosphate and Fecal Coliform in all monitoring stations. Fecal Coliform is at 54,000,000 MPN/100mL at Orchard monitoring station during the month of February. This implied that there is direct discharge of untreated domestic wastewater from nearby establishments in the area. BOD also exceeded the 7mg/L criteria for Class C water in some of the monitoring stations affecting the level of Dissolved Oxygen. TSS also exceeded in some of the monitoring stations during February. Temperature is below the minimum value of the range of 25-31 °C during the two months monitoring period in all monitoring stations. Nitrates, Chloride, Color and pH were all within the guideline for Class C water in all monitoring stations.

Ylang ylang River

Results of the water quality of Ylang-ylang River showed exceedances on Phosphate, Chloride, BOD, TSS and Fecal Coliform in most of the monitoring stations. Significant concentration of BOD at Alang-ilang Bridge station on January and June monitoring at 2,190mg/L and 2,232, respectively were noted thus affecting the level of Dissolved Oxygen dropping to 0.0 mg/L. This may affect the survival rate of organisms present in the water during that time.

Rio Grande River

Fecal Coliform showed exceedances in all monitoring stations during the Two months monitoring period. Highest count recorded was 16,000,000 MPN/100mL at Dulong Bayan station during January. For physico-chemical analysis, some monitoring stations exceeded the guideline for phosphate, BOD &TSS. The level of DO did not meet the 5mg/L minimum guideline as a result of the high concentration of BOD. Other parameters are within the guideline.

II.3 Issues and Concerns

Zoom accounts of representatives of government agencies, LGUs, and sectors (academe, NGO, PO, water utility) are being established for the conduct of meetings thru video conference.

III.1 IYAM-DUMACAA RIVER SYSTEM WATER QUALITY MANAGEMENT AREA (IDRS-WQMA)

The operationalization activities for the Iyam-Dumacaa River System WQMA implemented during the first and second quarter of this year include conduct of board meeting, water quality monitoring and other WQMA related activities. The Ten-Year Action Plan was approved and adopted during its first quarter board meeting on February 19, 2020.

Letters for the IDRS-WQMA covered LGUs was prepared for their adoption of the designation of WQMA and the Ten-Year Action Plan for the eventual preparation of their individual LGU Compliance Plan to the WQMA Action Plan.

Background

The IDRS-WQMA was designated by virtue of DAO 2018-11 “Designation of the Iyam-Dumacaa River System water Quality Management Area and Creation of Its Governing Board” dated July 2, 2018. It covers the watershed of Iyam-Dumacaa Rivers with an area of 19, 925.65 hectares. Iyam and Dumacaa Rivers drains the southern portion of Municipality of Lucban from the peak of Mt. Banahaw, thence to the city of Tayabas, thence to the city of Lucena, thence to the Tayabas Bay on the south. Dumacaa River is a major tributary of Iyam River. The two (2) rivers converge at Barangay Cotta, Lucena City before its final outfall to the Tayabas Bay.

Iyam and Dumacaa Rivers were both classified as “Class C” waterbody pursuant to NPCC Rules and Regulations now DAO 2016-08. Class C water is intended for: 1) Fishery Water for the propagation and growth of fish and other aquatic resources; 2) Recreational Water Class II for boating, fishing or similar activities; and, 3) For agriculture, irrigation, and livestock watering.

Operationalization Activities Implemented
Board Meeting

Pursuant to Section 15.1 of IDRS-WQMA Governing Rules, the board conducted its first quarter board meeting on February 19, 2020. The Ten-Year WQMA Action Plan was approved and adopted through Board Resolution No. 2020-01. The officers, members of Technical Working Group and sub-working group were elected during the meeting. Minutes of the meeting is attached for reference.

Water Quality Monitoring

Water quality samplings were only conducted on the months of January and February during the first quarter and on the month of June during the second quarter due the implementation of community quarantine measure for the COVID-19 pandemic. Ten (10) primary parameters were analyzed pursuant to DAO 2016-08 “Water Quality Guidelines and General Effluent Standards of 2016”. Water Quality monitoring was suspended on March to May, 2020 due to community quarantine. Results of laboratory analysis are shown in the table below.

Results of water quality monitoring of Iyam River showed high concentration of BOD during the month of January and Chlorides on the month of June at station 1. This affected the level of Dissolved Oxygen dropping to 0.0 mg/L at the same station. High concentration of BOD indicates a greater degree of discharge of untreated wastewater from both residential and commercial and industrial establishments within the drainage area of the river. Temperature is cooler below the minimum value of the range of 25-31˚C. Chloride at station 1 is high. This may be due to effect of tidal activities since the area is still considered within the mixing zone.

On the other hand, concentration of Fecal Coliform has significantly exceeded the guideline throughout the monitoring period in all monitoring stations with 1,700,000 MPN/100mL at station 1 on the month of January. The lowest value is 4,000 MPN/100mL at station 2 on the same month.

Results of Dumacaa River showed that Chlorides and BOD exceeded the guideline in some monitoring stations. The river also showed excessive contamination with fecal material from human and/or other animals as shown by high fecal coliform counts. Concentration of fecal coliform counts ranged from 2,300 to 2,800,000 MPN/100mL.

III.3 Issues and Concerns

One of the issues in the implementation of the program is the attendance of unauthorized representatives other than their officially appointed permanent and/or alternate representatives in the Governing Board by member government agencies and LGUs during board meetings which is not considered in the determination of a quorum.

The GB during its 2020 first quarter board meeting has agreed to send reminder letters to all members of IDRS-WQMA to send their officially appointed permanent or his/her alternate representative during meeting of the board. If the permanent and the alternate are not available to attend the meeting, a temporary representative with authorization from the permanent representative can attend the meeting pursuant to Section 15.1d of the IDRS-WQMA Governing Rules.

A.03.b.2.2.7 Manila Bay Rehabilitation Program

On January 27, 2019, DENR Secretary Roy A. Cimatu officially declared the start of the Manila Bay Rehabilitation at the Baywalk in Manila. The declaration, joined in the earlier event of Solidarity Walk from the Quirino Grandstand to the staging area (Baywalk), about 5,000 individuals, mostly representing the thirteen (13) Mandamus agencies, local government units, and private sector joined the calling in the “Battle of Manila Bay” to bring Manila Bay back to life.

In connection with the ongoing undertaking for the clean -up and rehabilitation of Manila Bay, activities were undertaken by this office and accomplished specific activities that is based on the Work and Financial Plan approved by the EMB Central office and as per operational plan for Manila Bay Coastal Strategic Program (OPMBCS) that would result to the realization of the stakeholders’ shared vision for Manila Bay and to the Court’s order of cleaning up, rehabilitating and restoring the Bay’s water to SB Class.
