Executive Summary

General

The Contractor, CMC di Ravenna, monitors its performance against the CEMMP obligations.

Because of this, it will record non-compliance where performance does not meet the original

obligations. In many cases this should not be taken to mean that the outcomes are bad and

where alternative courses of action have been adopted CMC and MWSS has recorded this.

This report highlights prevailing issues about the project. Only obligations which are assessed

as in progress, non-compliant (in specification and time schedule), and not applicable are

presented in the body of the report. A full review of the CEMMP obligations is presented in

the CA matrix in excel format.

The layout of this report followed recommended ADB monitoring report structure.

Assessment of compliance The following are the definition of remarks used to assess the CEMMP, EMP of IEE and EIA and other environment related project documents.

(a) COMPLIANT – completed according to schedule and specifications in the

CEMMP and other relevant ADB policies;

(b) NON-COMPLIANT – not completed according to schedule and specification

and/or not according to specification;

(c) NC time – completed beyond the date of completion stated in the CEMMP

(d) IN PROGRESS – partly compliant and pending for completion

(e) NOT APPLICABLE – obligations not applicable to AWTIP project

(f) CANNOT DOCUMENT COMPLIANCE – insufficient document or no

document provided to support assessment of compliance

A full review of the CEMMP and other relevant project documents on environment is

presented in Appendix Section 8.1.

Two grievance cases reported in the period July to December 2017.

Water quality monitoring started on August 2017. Portable turbidimeter and multimeter were

procured for in-situ measurements and monitoring of water. Monitoring using the

instruments started on October 2017.

A sound level meter was also procured to monitor sound levels onsite. Monitoring started on

October 2017.

Other monitoring and survey services/ consultancy procurement are in progress.

1 Introduction

1.1 Background

The Angat Water Transmission Improvement Project (AWTIP) is part of a bigger scheme of

modernization and improvement of the Metro Manila Water Distribution Network. The

water of the Angat basin, which is fed through the Umiray tunnel, provides around 35% of

the water for domestic use to the city of Manila. Currently the transportation of water from

Ipo dam basin to the Bigte sedimentation plant happens through 4 tunnels, 2 of which are

very obsolete. The progressive deterioration of the existing tunnels (2 of which were built

more than 75 years ago), or the occurrence of an earthquake (which is very likely since the

area is close to two active faults), may seriously compromise the provision of water to millions

of people.

The project is located in the province of Bulacan, at around 50 km north of Manila, close to

Norzagaray City, of 150,000 inhabitants which hosts several important cement industries and

which is easily accessible via highway or normal roads.

More than 95% of the water supply for Metro Manila comes from a single source: The

Umiray–Angat– Ipo, or Angat system. Water from the Angat reservoir is conveyed through

three parallel tunnels followed by six parallel aqueducts, to water treatment plants in Metro

Manila. The treated water is then distributed to households, businesses, and industries in

Metro Manila, and parts of Cavite and Rizal provinces. The transmission’s tunnel system

which is about 75 years old, has not been assessed ever since. The earlier tunnels, tunnels 1

and 2 are not in compliance with current structural and seismic requirements. These factors

could lead to serious interruptions of Metro Manila’s water supply. The proposed project will

construct the urgently required fourth parallel tunnel. This new tunnel will not increase system

capacity, but it will enable the rehabilitation or decommissioning of the upstream tunnels and

downstream aqueducts.

The proposed project aims to (i) help restore the full design capacity of the Angat systems

and thus ensure the sustainable provision of the water supply distribution system, and (ii)

mitigate the risk of a total loss of water supply to Metro Manila and portions of Cavite and

Rizal provinces. Both objectives are essential for the stable economic growth of Metro Manila

and the Philippines. The government has asked the Asian Development Bank (ADB) to

finance this investment. The figure below shows the general location of the project.

Contract Time Elapsed 579 c.d. or 37.12%

Delayed Activities:

1. No. 136: Slope Stabilization (Inlet) – The delay in the Slope Stabilization along inlet area

is primarily due to CMC’s claim to Redesign the Intake Structure and Slope Stabilization at Ipo dam area. Technically, the Variation on Design was approved last May 2017. MWSS Board of Directors declined the Variation on Cost. Thus, since CPF have an on-going project negotiation regarding Slope Stabilization within the area, the additional scope of work being claimed by CMC to AWTIP scope of work will be covered to Ipo Dam Slope Stabilization Project (IDSSP) being implemented by CPF.

2. Permanent Access Road – the works at the remaining areas of the Access road at IPO dam area, was on hold since 07 August 2017. The stoppage of work was CMC’s prerogative while waiting for the approval of Variation Order No.1

a. No. 123: Clearing and Grubbing b. No. 124: Subgrade Preparation c. No. 125: Road Excavation

3. Tunnel Excavation by TBM – The delay is caused mainly by the unforeseeable site

condition such as the ever- changing site condition and unforeseeable geologic feature such as transported materials, Karst-cavities and artesian aquifers discovered during the rock excavation. Due to the updated geological findings, the design of the outlet portal was revised with the introduction of the micropiles retaining wall, and extension of shotcrete area on both sides of the outlet portal. The position of the portal has been moved 10 m ahead from the original design because of this transported slope wash material and rock soil debris. Moreover, grout injection works was necessary to stabilize



5

the areas around the tunnel portal to avoid possible collapse or cave-ins during excavation. The rock excavation of the launching chamber prevented the TBM to be completely assembled and mobilized to the portal area. These works caused delay on the activities below:

a. No. 187 – Preparatory Works b. No. 188 – TBM Mobilization c. No. 190 – TBM Assembly

4. No. 196 – Production of Precast Segments – The delay in the precast production was due to the quality of cement used for the mix that cause slow curing time for demoulding. CMC utilized another cement supplier who is able to provide high early strength concrete, thereby producing increase in production of segments due to faster demoulding time. CMC also hired a specialist in precast rings/segment production, Mauro Spelozzi, to undertake the precasting process. His technical know-how, skills and experience will be optimized to mitigate the problem of low production rate.

2 Major Incidents – defined as an acute incident such as major discharge/emission or a fire/explosion, which

immediately or subsequently causes several serious injuries and/or fatalities, serious harm to environment and/or loss of substantial material assets.

3 Minor Incidents – an accident that causes minor damage. 4 Vehicle Incidents – when a motor vehicle strikes or collides another vehicle, a stationary object, a pedestrian, or an

animal 5 Near Misses – unplanned event that has the potential to cause, but does not actually result in human injury,

environmental or equipment damage, or an interruption of normal operation. 6 First Aid Cases – worker’s injury cases administered immediately after the injury occurs at the location where it

occurred. 7 Medical Treatment Cases – recordable incident involving injury or illness that has required management and care of

the patient above and beyond first aid, but not severe enough to be a reportable fatality or lost work day case or restricted work day case.

8 Restricted Work Cases – when a person is so injured that they cannot perform their normal duties. Therefore, they

are transferred temporarily to some other jobs (light duties). 9 Lost-Time Cases – refer to the number of lost-time injuries within a given accounting period, relative to the total

number of hours worked in that period.

4 Summary of Environmental Mitigations and Compensation Measures Implemented

A full review of the CEMMP, IEE, EIA EMP and other obligations is presented in the compliance matrix in Appendix Section 8.1 of this report. Below is a summary

of prevailing issues on mitigation and compensation issues. Details can be found in Appendix Section 8.1.

Environmental Aspect

Potential Impact Possible Approach/ Mitigating Measures

Compliance Status

Remarks

Water

Impact on surface water quality due to/ from: · Contaminants from materials used and construction activities and processes · Siltation from soil erosion, spoil disposal area, dewatering excavations, etc · Water quality Deterioration of water quality in Ipo Dam and Bigte river Tributary during construction

· Implement hazardous waste management that minimizes, properly segregates and promptly and properly disposes of generated hazardous wastes. · Store hazardous construction materials in appropriately contained and elevated area and at least100 m away from surface water bodies. · Implement corrective action, when trigger thresholds of water quality are reached. · During construction, the contractor shall take corrective action to reduce concentration to below the standard.

Partial

High coliform was reported in segment of surface water where there are communities along the riverbanks prior to the start of construction activities. This trend was already noted during the collection of baseline information in 2013 -2014. Please note that Ipo Construction site was on stop work status since 2017 September. Portalets are provided and regularly collection is implemented in all construction sites - Ipo and Bigte. Waste onsite are segregated into biodegredable, non-biodegradable and residuals. There are designated bins for each type of waste, color coded and labeled. Waste are collected every Tuesday and Thursday by Brgy Bigte. CMC and Brgy Bigte has a service contract for garbage and hauling disposal from May 2017 to December 2017.



26



Compliance Status

Remarks

The first water quality sampling was conducted by CMC last August 2017 with the following parameters: Temperature, pH, electric conductivity, tubidity, color, TDS, ORP, dissolved oxygen, BOD, coliform (Total and Fecal) and heavy metals (See sampling location and results on the report). Weekly monitoring of water turbidity and other in-situ paramters using portable water meters started on October 2017. Testing is done weekly by CMC Envi, Health and Safety Officers (See sampling location and results on the report)

Air Quality and Noise

a) Deterioration of ambient air quality due to dust and gas emissions from: · Earthworks and other construction processes; tunneling (TBM) • stockpiling of aggregates and spoils, and conveyance of spoils to disposal areas; • increased transport activities in the construction areas and along Ipo Road;

In active work sites: Use of dust curtains / nets to capture dust from the construction sites

Apply dust suppression techniques, e.g., watering with bowsers, sheeting particularly at Bigte area Require trucks, particularly those hauling aggregates, to have secure covers. · Limit engine idling to 5 minutes. · Prohibit open burning of vegetation and other waste in the project area

Partial

No dust curtains/net have been installed. Not yet necessary. This will be installed at the outlet portal area once excavation activities commence and measured air duality parameters such as total suspended particles and PM 10 are almost near the standard limits of air quality.

Dust suppression such as watering of road has been implemented already.

Open burning is not practiced onsite. ALL CMC drivers have defensive driving training. It is observed that speed limit along Ipo road was not followed mostly by the community.



27



Compliance Status

Remarks

• Where haulage traffic exceeds 200 heavy goods vehicles (HGV) per day • burning of vegetation and wastes; and • operation of mechanical equipment

· Ipo Road, main access road, other roads in the Project area, limit speed of all construction vehicles to maximum of 40 kph on the access road to, and maximum of 30 kph in the site · Control noise at source, e.g. low noise plant, muffling, acoustic screening, switch off campaigns · Restrict use of noisy and highly vibrating equipment from 8AM-5PM. Necessary overtime work should: a) not go beyond 9:00PM; b) observe regulated noise and vibration levels; c) not use noisy and highly vibrating equipment; and d) should be coordinated with the barangay and affected households. · Manage the ins and outs of hauling trucks. Spread out the schedule of material, waste and spoil transport in the day (off-peak hours). .· Enforce the rule of no blowing of horns. · Strictly enforce upon workers the compliance with wearing of ear mufflers, especially those who are operating equipment.

Agreement with CRL Laboratories for air quality monitoring is now in place (24 August 2017). The air quality sampling dates will be scheduled once the Tunnel Excavation starts.

4.2 Water Quality Monitoring Program

4.2.1 Summary of Water Quality Monitoring for Bigte and Ipo River (August, December

2017)

Fresh water quality sampling along Angat River and laboratory inspection

in CRL Laboratory in Clark, Pampanga was carried out 30 August 2017 by

Selam Tesfaye, Rusty Romero and Pam Constante. A total of 4 samples

were collected. Due to heavy rains, the samples in Bigte Creek and Sta

Maria River was collected in 5 September 2017.

The water quality sampling activity in Bigte area on 31 August 2017 was

aborted due to heavy rains. It was done in 5 September 2017.

A portable turbidimeter was purchased by CMC to conduct a daily turbidity

monitoring at the water bodies near the construction sites in December

2017.

Video and photo documentation along Ipo River (Angat River) is ongoing

while procurement of water quality instrument and laboratory analyses

service is in progress.

4.2.2 Results of Bigte and Ipo River (August, December 2017)

Below are sampling points and complete laboratory results of the water

quality samples collected in August and September.

Complete results were transmitted in October 2017. Measures in red are

parameters with exceedances according to DAO 2016-08. The results

presented were compared with the baseline (2013 wet season).

10 Discharge levels should be compared to the relevant discharge standards and/or performance indicators noted in

the EMP. Any exceedances should be highlighted for attention and follow-up. In addition, discharge levels could be compared to baseline conditions (if baseline data is available) and described in qualitative terms or be evaluated based on a ranking system, such as the following:

1. Very Good (overall conditions are generally improved) 2. Good (conditions are maintained or slightly improved) 3. Fair (conditions are unchanged) 4. Poor (conditions are moderately degraded) 5. Very Poor (conditions are significantly degraded)

Additional explanatory comments should be provided as necessary.

4.2.5 Assessment11 of Bigte and Ipo River (August, December 2017)

For Bigte River, only fecal and total coliform were reported in all the

sampling locations (SWB1, SWB2, SWB3 and SWSM1) and exceeded the

DENR 2016-08 standards during the 2017 August-September sampling

period. SWB2 had the highest reported fecal and total coliform with 35,000

and 92,000 respectively. In comparison to the baseline data (2013 wet

season data), total and fecal coliform results have decreased in all the

sampling locations except from SWB3 and fecal coliform at SWB2.

All in-situ parameters measured in Bigte River during the 2017 December

sampling did not exceeded the DENR 2016-08 standard.

For Ipo River, all sampling locations had fecal and total coliform but only

SW IPO4 exceeded the DENR 2016-08 standard with 5,400 (both total and

fecal coliform). In comparison to the baseline data (2013 wet season data),

fecal coliform has increased while total coliform has decreased in SW IPO4.

4.2.6 Summary of Water Quality Assessment in Basin 1(October 2017)

A sample from Basin 1 was collected last October 2017 to establish baseline

data since these water will be used in the construction of the tunnel and

will be treated afterwards in the water treatment plant. Samples were

collected by Selamawit Tesfaye and a representative from CRL

Laboratories.

indicators noted in the EMP. Any exceedances should be highlighted for attention and follow-up. In addition, ambient environmental conditions could be compared to the baseline conditions (if baseline data is available) and described in qualitative terms or be evaluated based on a ranking system, such as the following:

1. Very Good (overall conditions are generally improved) 2. Good (conditions are maintained or slightly improved) 3. Fair (conditions are unchanged) 4. Poor (conditions are moderately degraded) 5. Very Poor (conditions are significantly degraded)

5 Key Environmental Issues

5.1 Key activities implemented

The following activities are currently implemented:

(i) The following monitoring is being established: Water quality monitoring

o Water quality monitoring started on August 2017. CMC also procured portable turbidimeter and multimeter to take in-situ measurements daily on the established sampling points and bodies of water near the construction sites.

Air and Noise quality monitoring

o Agreement with CRL Laboratories for air quality monitoring is

now in place (24 August 2017). The air quality sampling dates will

be scheduled once the Tunnel Excavation starts. It will be done

quarterly. Target dates of the air quality monitoring are as follows:

February 6-8, 2018

May 8-10, 2018

August 7-9, 2018

November 6-8, 2018

February 5-7, 2019 o A sound level meter was procured by CMC to monitor the noise

level during construction period as one of the requirements of ADB and DENR. Noise monitoring started on 28 October 2017 and will be continuously done weekly.

5.2 Key Issues Identified

Freshwater water ecology monitoring

o Target date of the freshwater monitoring are as follows:

April 2018

August 2018

Social and economic survey

o Target date of the socio-economic survey and monitoring are as

follows:

September 2018

Social and environmental awareness

o Bulletin boards for IEC purpose were installed in the barangay

halls of Brgy Bigte and San Mateo on June 19-20, 2017. Third

letter to NCIP in relation to FPIC application was sent on 15

June 2017. Target date of the social and environmental

awareness campaign for the residents and students will be done

on during:

Started in July 2017 and monthly updates thereafter or

in cases such as employment requirement of the

construction project; and major construction activities

and deliveries of largo goods that will have potential

impact to the environment as well as community health

and safety impact

Public Health and safety

o public health and safety campaign started in September 2017 and

should continue until the end of construction period. This activity

should be continued by MWSS during the operational phase.

Procurement of other laboratory services, consultancy services and surveys is on-

going.

(i) MWSS has no Construction Supervision Engineer Team where an

environment specialist is included. CMC provides environmental and

social technical inputs to the project.

Valid Grievance Cases 2

Invalid Grievance Cases 0

Unresolved Grievance Case from previous months

0

Pending Valid Grievance Cases 0

Resolved Grievance Cases to date 2

Two grievance cases have been reported as of December 2017.

1. Dumagats expressed their complaint during the FPIC meeting in July 4,

2017 on the turbidity of the water of Ipo River which is caused by the

runoff during heavy rain. The case was investigated by Rusty Romero and

Pamela Constante. There was no rain at the time of investigation.

Localized increase in turbidity is observed. Video / photo documentation

during heavy rain was requested from Danielle Scalaro and Alex Lim to

monitor water turbidity by visual inspection while waiting for the

instruments and water quality sampling. To date, video documents show

that the turbid water comes from Sapang Munti and upstream of Ipo

Dam.

2. A complaint was received on July 18, 2017 by CMC which was filed by

residents of Calle Onse (adjacent to the Industrial Area in Brgy Bigte

regarding the generation of dust and mud along the road. This case was

investigated by CMC H&S together with representative of Calle Onse.

CMC already made provision of a canal across the Industrial Area. The

problem is not attributed solely to CMC but residents addressed grievance

to CMC hoping to get some help. The case was closed and H&S has the

detailed documentation.

7 Conclusion and Recommendation

7.1 Overall Progress of Implementation of Environmental Management

Measures12

The overall progress can be assessed as fair. The project construction

phase started in December 2016. Temporary and major facilities and work

areas have been established from July to December 2017. The TBM already

arrived onsite and will start operating on March 2018. In such construction

activities, potential environmental impacts associated to tunnel

construction per se is yet to be observed until the excavation work will

commence. Water quality monitoring has started on August 2017.

Portable water meters (turbidimeter and multi-meter) have arrived and in-

situ monitoring on established sampling points and water bodies onsite

started on October 2017. For air quality monitoring, agreement with CRL

Laboratories for air quality monitoring is now in place (24 August 2017).

The air quality sampling dates will be scheduled once the Tunnel

Excavation starts. A sound level meter was procured by CMC to monitor

the noise level during construction period Noise monitoring started on

October 2017 and will be continuously done weekly. Other monitoring and

survey services/ consultancy procurement are in progress.

12 Overall sector environmental management progress could be described in qualitative terms or be evaluated based

on a ranking system, such as the following: 1. Very Good 2. Good 3. Fair 4. Poor 5. Very Poor

July. Please note that IPO construction site is on stop work status from August -

December 2017. No spoil delivered to Ipo Elementary School as of December

Construction engineers made inspection and the following are some observation:

1. The materials are hauled from the construction sites using dump truck. This

size of vehicle cannot enter the school's premises due to small gate. Only small

vehicle can fit the gate of the school.

excavation works.

These observations are preliminary and will be discussed with th eschool

personnel. This concerns have to be dealth with by the school prior to te delivery

of the spoil.
