1.0 Introduction

The RIIDP is composed of selected road sections for rehabilitation and improvement under the Department of Public Works and Highways (DPWH). It is funded by the Asian Deve lopment Bank (ADB) through Loan 2836-PHI: Road Improvement and Institutional Development Project (RIIDP), with the supporting funding from the OPEC Fund for International Development (OFID).

CP Lot 4.1: Dumaguete North Road Project, Manjuyod-La Libertad Road Section is one of the road packages of the RIIDP. It starts from KM. 53 + 428.81 (Boundary point with Dumaguete City along the Manjuyod-Road Section) to KM. 108 + 967.00 (Boundary point to La libertad-Vallehermoso Road Section). From the start of the project in the Municipality of Manjuyod, the project road proceeds to a northward direction over flat, gentle terrain to rolling and mountainous terrains and traverses several towns of Negros Oriental namely, Bindoy, Ayungon, Tayasan, Jimalalud and part of the Municipality of La-libertad. The entire stretch of the road is under the jurisdiction of the DPWH Negros Oriental First Engineering District with its new office site in the Municipality of Bindoy. The road section covers a gross length of 55.538 kilometers with exceptions. The exempted sections are 25 bridges (0.962 KM.) and the areas covered by the 2015 budget for DPWH Infra Project which covers a total length of 1.624 ki lometers. The road section is a combination of existing ACP that covers a length of 8.313 kilometers and existing PCCP with a length of 47.225 kilometers. The net length is 52.952 kilometers.

This 24-hour air quality and noise level sampling is conducted as part of and in compliance to the requirements of the ADB approved IEE Environmental Management Plan (EMP).

Procedure: USEPA, 40 CFR 50, Appendix B

Sampling Equipment: Graseby High Volume Sampler (for 24 hours sampling)

1 Ambient Air Quality and Noise Level Monitoring (April 2018) Hunan Bridge and Road Corp.

Method of Analysis: Gravimetric Method

Sulfur Dioxide (SO 2)

Procedure: USEPA, 40 CFR 50, Appendix A

Sampling Equipment: Graseby Gas Bubbler Sampler (USEPA Compliant)

Method of Analysis: Pararosaniline Method

Nitrogen Dioxide (NO2)

Reference Procedure: Air Pollution Monitoring Manual, EMB-1994

Sampling Equipment: Graseby Gas Bubbler Sampler (USEPA Compliant)

Method of Analysis: Colorimetric, Greiss Saltzman

After each sampling activity, all sam ples were preserved in an ice box while the filters that were used to collect TSP and PM1o were placed inside a sealed plastic container. The samples were immediately transported to ELARSI, INC., a DENR-EMB accredited laboratory for testing and analyses.

2.2 Noise Measurement

A precision type, digital sound level meter was used in noise measurement. The said instrument is an AM PROBE SM-10. As declared in the Certificate of Conformity, with the accuracy of 1.5d8, the sound level meter fulfills the guidelines of 89/336/ECC. The sound level meter conforms also with DIN EN 60651, (IEC651), Class 2 Standards.

Th e sound level meter was ca librated by Switchtek Measurement Systems using a Lutron Sound level calibrator model SC-940. By comparative technique, Standard Sound Generator was introduced to the AMPROBE at a constant value of 94.0 dB and at a uniform frequency of 1000 Hz. Data were gathered and tabulated.

The results of the ca libration found that there was a +-0.00 dB standard error between the reference reading and the test reading with a confidence level of not less than 95%. The procedure of the test is traceable to the requirement of OIML 88 guidelines, IEC 60942 Type II, a Standard of the NIST and National Physical Laboratories (NPL).

Right after collecting ambient air samples, in the same t wo sampling locations, Noise measurement was conducted. Fifty (50) instantaneous readings in decibels - A weighing (dBA) were recorded for about 2 to 3 minutes. Statistical values such as minimum, maximum, mean and median were determined from the readings.

5.0 Discussion of Results

5.1 Ambient Air Sampling

The results of the aforementioned sampling activities were compared to the National Ambient Air Quality Standards for Source Specific Air Pollutants (NAAQSSAP) as stipulated in Table 3, Section 1, Rule XXVI, Part VI I of the Implementing Ru les and Regulations (IRR) of the Philippine Clean Air Act.

The Ambient Air Sampling for all stations was conducted on a sunny weather condition with light wind direction. The results of the sampling analysis shows that the ambient concentrations were all within the DENR Standards limit in all sampling stations.

6 Ambient Air Quality and Noise Level Monitoring (April 2018) Hunan Bridge and Road Corp.

5.2 Noise Measurement

The DENR Environmental Quality Standards for Noise is based on the 1978 Rules and Regulations of the National Pollution Control Commission. AS per these regulations, noise is measured in 11A" weighting network and 11slow response" with different limits for various time of the day and area category.

The results of noise level measurement were compared to the standards based on the existing land use within the sampling locations. All stations are located at mountain area and residential area/site, therefore considered Class C (Commercial Area). All noise level measurement were all within the DENR limit for Class C area.

The main sources of noise observed during sampling were mostly from vehicles and people passing t hru Western Nautical Highway of Jimalalud and Tayasan, Negros Oriental.

1.0 Introduction

The RIIDP is composed of selected road sections for rehabilitation and improvement under the Department of Public Works and Highways (DPWH). It is funded by the Asian Development Bank (ADB) through Loan 2836-PHI: Road Improvement and Institutional Development Project (RIIDP), with the supporting funding from the OPEC Fund for International Development (OFID).

CP Lot 4.2: Dumaguete North Road, La Libertad- Vallehermoso Road Section is one of the road packages of the RIIDP.

It starts at KM 108+967 at La Libertad- Vallehermoso Section and stretches northward up to the end of the project at KM 150+475.772 (the beginning point of Vallehermoso- San Carlos City/ Calatrava Boundary Road Section or the Bacolod North Road). It runs over a flat to rolling to mountainous terrain and traverses the town of La Libertad, Guihulngan and Va llehermoso and is under the jurisdiction of Negros Oriental First Engineering District Office. The road section covers a gross length of 41.509 kms with exceptions, wherein, the exempted sections are all bridges 0.332 kms and the 2015 budget for DPWH Infra Project which covers a length of 8.891 kms of road length. The road section is a combination of existing ACP covering a length of 25.655 kms and existing PCCP with a length of 15.854 kms. The net length is 32.286 kms.

This 24-hour air quality and noise level sampling is conducted as part of and in compliance to the requirements of the ADB approved IEE Environmental Management Plan (EMP).

2.0 Sampling Methodology

2.1 Ambient Air Sampling

The DENR standard ambient sampling equipment and analytical procedures were used in the sam pling activity. These equipment and procedures are specified below:

Particulate Matter (PM10)

Procedure: USEPA, 40 CFR SO, Appendix B

Sampling Equipment: Graseby High Volume Sampler (for 24 hours sampling)

Method of Analysis: Gravimetric Method

Total Suspended Particulates (TSP)

Procedure: USEPA, 40 CFR SO, Appendix B

Sampling Equipment: Graseby High Volume Sampler (for 24 hours sampling)

Method of Analysis: Gravimetric M ethod

1 Ambient Air Quality and Noise Level Monitoring (April 2018) Sino Road and Bridge Co. Ltd

Sulfur Dioxide (SO2)

Procedure: USEPA, 40 CFR 50, Appendix A

Sampling Equipment: Graseby Gas Bubbler Sampler (USEPA Compliant)

Method of Analysis: Pararosaniline Method

Nitrogen Dioxide (NO2}

Reference Procedure: Air Pollution Monitoring Manual, EMB-1994

Sampling Equipment: Graseby Gas Bubbler Sampler (USEPA Compliant)

Method of Analysis: Colorimetric, Greiss Saltzman

After each sampling activity, all samples were preserved in an ice box while the filters that were used to collect TSP and PM10 were placed inside a sealed plastic container. The samples were immediately transported to ELARSI, INC., a DENR-EMB accredited laboratory for testing and analyses.

2.2 Noise Measurement

A precision type, digital sound level meter was used in noise measurement. The said instrument is an AMPROBE SM-10. As declared in the Certificate of Conformity, w ith the accuracy of 1.SdB, the sound level meter fulfills the guidelines of 89/336/ECC. The sound level meter conforms also with DIN EN 60651, (IEC651), Class 2 Standards.

The sound level meter was ca li brated by Switchtek Measurement Systems using a Lutron Sound level calibrator model SC-940. By comparative technique, Standard Sound Generator was introduced to the AMPROBE at a constant value of 94.0 dB and at a uniform frequency of 1000 Hz. Data were gathered and tabulated.

The results of the calibration found that there was a +-0.00 dB st andard error between the reference reading and the test read ing with a confidence level of not less than 95%. The procedure of the test is traceable to the requirement of OIML 88 gu idelines, IEC 60942 Type II, a Standard of the NIST and National Physica l Laboratories (NPL).

Right after collecting ambient air samples, in t he same two sampling locations, Noise measurement was conducted. Fifty (SO) instantaneous readings in decibels - A weighing (dBA) were recorded for about 2 to 3 minutes. Statistical values such as minimum, maximum, mean and median were determined from t he readings.

6 Ambient Air Quality and Noise Level Monitoring (April 2018) Sino Road and Bridge Co. Ltd

5.2 Noise Measurement

The DENR Environmental Qua lity Standards for Noise is based on the 1978 Rules and Regulations of the National Pollution Control Commission. AS per these regulations, noise is measured in "A" weighting network and "slow response" with different limits for various time of the day and area category.

The main sources of noise observed during sampling were mostly from vehicles and people passing thru Western Nautical Highway of City of Gu ihilngan, Negros Oriental.

Site Visit conducted by:

Herbert Narisma - CTC Environmental Specialist, National with: Joel Buenaventura - Resident Engineer - CSC - Lot 4.2

Findings:

I. Compliance to Statutory Requirements and Contract

1.1. Compliance to Environmental Permits and Licenses

The Contractor has still not complied with the GOP statutory requirements by securing the Environmental Compliance Certificates (ECC) from the DENR-EMB. While the 3rd party supplier quarries have already complied, the batching plant and construction and workers camp compound which is owned by the Contractor is yet to secure an ECC. Simi larly, a building permit has already been issued to the Contractor's facilities but there is yet no Mayor's permit.

Contractor's Camp, Stone I Status i Crusher, Batching ' Plant I Partially Complied Mayor's Permit With building permit but no Mayor's permit yet 2017 Building Permit No. 001706018 dated May 31, 2017 issued by the City of Guihulngan.

1.2. Compliance to ADB-IEE-EMP Requirements and Contractual Obligations

The Contractor has already submitted a Contractor Environmental Management and Monitoring Plan (CEMMP). However, as per comments from the ADB, the CEMMP needs to be revised and resubmitted. There is yet no submission of the revised CEMMP. The Contractor also did not conduct 24-hr air quality and noise level sampling for the 2nd semester of 2017 at sensitive areas along the project alignment. Please see table below for the compliance of the Contractor to the requirements of the contract and the ADB-IEE EMP. ------Reference Compliance Status Action Required/Remarks - Contractor's Environmental Not complied Submit CEMMP Management Plan (CEMP) Appointment of Environment and Complied A new safety officer was Safety Officer (ESQ) (Mr. Alman Joseph appointed but is not an accredited Ymalay PCO by the DENR.

Project Alignment

3. Flagmen are properly stationed, wearing PPEs and equipped with --2-way----'- radios.------~ Contractor's Camp/ Batching Plant

4. The Contractor's camp/ batching plant compound is very muddy. The nud is carried by the wheels of the trucks to the paved highway which makes the national road very dusty when the mud dries up. The Compund is located in the middle of the city and residences and public and commercial establishments. The dust has been the subject of numerous informal complaints but has not been acted upon by the Contractor.

5. Waste segregation bins are present. However, these were not properly utilized. Solid wastes were also noticed at the motor pool and storage areas in the compound. A structure labeled as a material recovery facility (MRF) was constructed but is still not being used. Recyclable materials were found outside of the MRF.

Ill. Status of Previous Findings and Recommendations:

The list of recommendations from previous site visits are shown in the table below together with the compliance status as of November 2017.

I Finding Date Status 1. Secure Environmental Compliance CSC Site Visit - July Not complied Certificate (ECC) from the DENR-EMB 13-14, 2017 i immediately since construction works are already ongoing at the batching plant. 2.

Clean the area along the canal at the CSC Site Visit - July Complied back of the material storage facility and 13-14, 2017 motor pool. 6. Install waste segregation trash bins in the CSC Site Visit - July Partially Complied batching plant and workers/base camp 13- 14, 2017 complex. In accordance with RA 9003, label or color the trash bins to indicate biodegradable and non-biodegradable wastes. Identify a specific area for storage of other wastes/Material Recovery Facility (e.g. busted lamps, used tires, empty drums, etc.) and should be properly segregated. 7. Submit revised CEMP as soon as CSC Site Visit - July Not complied possible. 13-14, 2017 8. Mobilize Environment and Safety Officer CSC Site Visit - July Partially Complied as soon as possible. 13-14, 2017

IV. Recommendations

1. Implement mitigating measures to prevent mud from being carried into the national highway which causes dust when it dries by improving the muddy access road in the contractor's camp/batching plant compound. Water showering on the mud to prevent dust is not the solution as washed away mud goes to the canals and contributes to the siltation of the waterways. 2. Secure the ECC for the contractor's camp/batching plant and the stone crushing plant, if required, as soon as possible. The facility is already in violation of PD 1586 and its implementing rules and regulations. 3. The Safety Officer should attend training and apply for PCO accreditation as required by the DENR-EMB. 4. Waste segregation bins installed in the batching plant should be properly used. Orient workers on proper solid waste management and improve housekeeping. 5. Use the newly constructed Material Recovery Facility (MRF) for storage of other recyclable wastes/ (e.g. busted lamps, used tires, empty drums, etc.) and should be properly segregated. 6. Make a drainage with impermeable flooring around the motor pool draining into an oil and water separator. Specify final disposal procedure for used oil and other materials in the MRF. 7. Prepare and submit CEMP soonest. 8. Conduct 24-hour air quality (TSP and PM10) and noise level sampling at areas with sensitive receptors for the 1st semester of 2018 as stipulated in the ADB-IEE EMB .

Findings:

I. Compliance to Statutory Requirements and Contract

1.1. Compliance to Environmental Permits and Licenses

The Contractor has complied with the GOP statutory requirements by securing the Environmental Compliance Certificates (ECC) from the DENR-EMB for the Contractor's camp/batching plant compound. However, the contractor is reminded that one of the conditions of their ECC is the regular submission of quarterly self-monitoring reports (SMR) and semi-annual compliance monitoring reports (CMR) to the DENR-EMB. Non• submission will result to Notice of Violations from the DENR-EMB. Compliance to this requirement will be checked in the next site visit.

The LGU building permit for the contractor's office and workers camp has already been acquired while those for the batching plant, stone crusher warehouse and motor pool have already been applied for and are in process.

The Contractor does not operate a quarry but buys aggregates from suppliers thus there is no need to verify statutory compliance.
