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.
No grievance case reported in the period January to June 2017.
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.

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

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

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. The construction camp is near the riverbank and might be a potential contributor to poor surface water quality. Hazmat identified at this stage of construction is limited to oil, lubricants used by heavy equipment and vehicles. Most vehicles used are brand new. Maintenance is done off site. Temporary Hazmat disposal area will be located in the Industrial Area and is planned to be constructed when excavation of the tunnel commences.

This is considered partial as no water quality sampling/ monitoring has been done yet. Procurement process for portable water quality meters are on-going. Request for quotation has been sent to Brownasia Tech Inc. Request for quotation for the conduct of the water quality has been sent to CRL Laboratories.
Air Quality and Noise
a) Deterioration of ambient air quality due to dust and gas emissions from: · Earthworks and other construction processes; tunnelling (TBM) • stockpiling of aggregates and spoils, and conveyance of spoils to disposal areas; • increased transport activities in the construction areas and along Ipo Road; • Where haulage traffic exceeds 200 heavy goods vehicles (HGV) per day • burning of
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
Partial
No dust curtains/net has been installed. 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 has been implemented already. Open burning is not practiced onsite

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, only temporary facilities and work areas
has been established from January to June 2017. In such construction
activities, potential environmental impacts associated to tunnel
construction per se is yet to be observed until the excavation work will
commence. Only impacts such as generation of dust and slight increase
in turbidity of the surface water in Bigte Creek is observed. The turbidity
of Angat River is attributed to other activities and physical conditions
upstream of Angat River. Dust generation is mitigated through regular
watering and cleaning of roads. For turbidity, visual monitoring is done
regularly through photograph and video documentation. Procurement
process of water quality portable meters are still on going. Request for
quotation has been sent to Brownstone Asia-Tech Inc. Once the meters
arrived, monitoring of turbidity and other water parameters will be done
regularly.
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
Additional explanatory comments should be provided as necessary.
