III. RESULTS OF ENVIRONMENTAL MONITORING

3.1. RA 8749: AIR ENVIRONMENT

3.1.1. Ambient Air Quality Monitoring System (AAQMS) Results

Ambient air monitoring is important to ensure that the stakeholders are breathing clean air that is

within the set standards. The current period is now in the Operations and Maintenance (O&M) regime

thus monitoring stations covered are those specified in the ECC and in accordance to DENR’s

recommendation. All sampling and analytical procedures conform to those required by the Bureau and

are performed by accredited service provider and laboratory. Table 2 summarizes the monitoring

activities made within the coverage period.

Results of the ambient air parameters monitored at the two (2) continuous stations defined in Table 2

with an averaging time of 24 hours generally concludes that the levels are well within the background

and standard values. On the average, the PM-10, SO2 and NO2 levels at station 1 and station 2 are below

the given standards - no exceedances were observed for all parameters. Tables 3 to 5 shows a summary

of the monthly data in the AAQMS while Figures 1 to 2 is a summary of the meteorological conditions

gathered within the coverage period. Figures 3 to 5 show graphical representations of the data. For the

coverage period, the prevailing wind directions are from the Northwest of station 1 and from Southeast

of station 2 with a maximum speed of 2.5 mps and 8 mps respectively.

Networking and communication to the central station is still currently being resolved but does not

interfere in the monitoring as data can still be manually collected at the two (2) off-site stations.

3.2. RA 9275: WATER ENVIRONMENT

3.2.1. Groundwater

Although, KSPC does not make use of groundwater for industrial and domestic operation , still

groundwater quality are monitored in compliance with the EIS and to ensure that groundwater being

utilized by the stakeholders are within the standards set according to its use. Table 9 shows the

groundwater monitoring results of the coverage period including that of the previous periods (May 2013

to Sep 2013) while Attachment 2 contains the trending graphs (from the start of monitoring up to the

present period) of the critical parameters with respective DENR standards. Sampling locations are

indicated in Attachment 1. Generally, the monitoring results indicate that groundwater stations tested are

still within acceptable levels but are not recommended for drinking. Though some of the results are not

within the standards, they are all within the background levels and trend of the baseline data from the EIS,

the MMT, and previous monitoring results. It is important to consider however that the power plant does

not withdraw groundwater or discharge effluents to inland surface waters. Thus, any adverse impact to

the community’s groundwater is most likely due to domestic activity and natural earth movement.

The Total Dissolved Solids (TDS) levels are high compared to the standard which could have an effect on

the taste of the ground water but the values are well within the baseline. This is again, as mentioned in

the previous reports, attributable to the natural background of the area. For the chloride levels, all

stations displayed desirable results. As mentioned in the first paragraph, it is highly recommended that

these deep wells be not used for drinking.

3.2.2. Marine Water

It is important to monitor the marine water quality of the nearby sea of the power plant since it is where

the treated water effluent generated from the plant operation are being discharged. Table 10 shows the

marine water monitoring results within the coverage period including that of the previous period (May

2013 to Sep 2013) while Attachment 2 contains the trending graphs of the previous results of critical

parameters with respective DENR standards. Sampling locations are indicated in Attachment 1. Generally,

the monitoring results indicate that there have been no adverse impacts to the receiving marine

environment. Most parameters fall within acceptable standards set by DAO 34 (Water Class SC).

Furthermore, most of the current data falls around the same range to those of the previous period’s

results including that of the MMT Baseline Monitoring Activity.

3.2.3. Water Effluents

Effluents of the power plant are from the sanitary treatment system, which processes all domestic

effluents to acceptable levels before it is discharged to the sea, storm water, and cooling seawater (at a

higher temperature). There are four (4) sanitary treatment systems in the power plant and 2 storm drains

to the sea. Each storm drain discharges effluents from 2 sanitary treatment systems together with the

rain/storm water. On the other hand, cooling water is discharged through the submerged discharge tunnel,

154 m off-shore.

Generally, the effluents of the power plant are within the national and World Bank standards. One

outstanding result would be the high TSS value at the cooling effluent (68 mg/L). The result is more than

the World Bank Standard but lesser than the DENR standard. TSS is quite high since the cooling water used

is seawater. Table 11 summarizes the results of these parameters in comparison to these standards.

3.2.4. Thermal Discharge

According to the standards, the mixing zone border should not experience a temperature increase of more

than 3°C. The baseline temperature shall be that of the ambient seawater while the mixing zone has a

radius of 100 m from the discharge point. The water temperatures were measured in the morning and

afternoon last September 11, 2013 to assess the environmental performance of the power plant. Table 12

presents the results. Figure 8 shows a map of the submerged discharge area and the sampling points.

Results show that the thermal effluents are within the national and World Bank standards.

Hazardous waste in the plant site includes waste oils, busted fluorescent lamps, and contaminated

containers. Within the coverage period, no wastes were disposed. These are currently stored in the

designated storage areas in the site. Contaminated containers were also cleaned and re-used as trash cans

and containers of prepared chemicals. As soon as these wastes are ready for disposal to DENR-accredited

treaters, KSPC will accordingly inform DENR-EMB through this report. Generated industrial wastewater is

being treated in the centralized wastewater treatment facility. Water produced are being reused for dust

suppression and firefighting. Mixed chemical wastes with mercury are placed in a tightly closed bottle which

is stored in the laboratory area for future treatment. Table 14 below shows the summary of generated and

stored hazardous wastes within the reporting period.

3.3.3 Naalad Riprapping Update

Currently, the project status is still in the acquisition of permits and licenses phase, particularly

that from DPWH. The overall project consists of the following activities:

1. Excavation and dredging

2. Rip rapping

3. Opening of new river route

4. Backfilling

Backfilling of excavated earth material shall be the last phase of the project. Ash shall not be used

as backfilling material and shall not be disturbed from its current state right now. Figure 9 below

shows the existing and planned rerouting and riprapping, while Figure 10-11 shows the site

condition and the works started for the rerouting.

3.4. RA 9003: SOLID WASTE

Solid wastes in the power plant are categorized as domestic/office and industrial. For the coverage period, a

total of 11,735 kg of domestic/office solid wastes were disposed of or collected by the Naga City LGU.

Industrial solid wastes in the power plant are either coal ash or sludge. Sludge from the wastewater

treatment plant was tested using the Toxicity Characteristic Leaching Procedure (TCLP) to determine

whether it is hazardous or not. Previous results indicate that these are within the limits for industrial waste.

Because of its very low generation rate (below 50 MT/year), KSPC will be disposing and mixing its sludge

with the coal at very low percentages depending on the production rate.

The power plant’s coal ash (fly ash; bed ash will be tested in the next quarter) was also tested using TCLP

and results also classified it as solid industrial waste (See Attachment 3). All the coal ash generated was

recycled by CEMEX (APO Cement) in their cement manufacturing business. Ash generation and disposal

activities for this period are more stable due to the very low ash quality of the coal fired compared to the

previous period. Table 15 summarizes the industrial and solid waste quantities generated and the respective

disposal methods.

IV. CONCLUSION

Based on the environmental monitoring results for the period of July to September 2013, the 2x100 MW Cebu

Power Plant Project has not caused any undesirable effect to the nearby surroundings. This is in line with the

company’s goal for sustainable development. The availability of recycling options for the coal ash is a positive

sign that more quantities if not all of the ash can be disposed of through sustainable means. The findings in

this report will be discussed in KSPC’s Multi-Partite Monitoring Team (MMT) and due recommendations will be

made. Certificates of analyses are in Attachment 3 while Attachment 4 contains the rest of the sampling

pictures.
