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.

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 levels at station 1 and station 2 are below the given

standards. SO2 and NO2 parameters are within the standard limits at station 1 and no exceedances were

observed at station 2 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 West of station 2 with a

maximum speed of 4 mps and 8 mps respectively.

The filter issue on the PM-10 analyzers is already resolved with no erroneous data obtained for the

coverage period. 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.

3.1.2. Manual Ambient Air and Noise Monitoring

Ambient air monitoring results at the four stations indicated in Table 2 have not exceeded the reference

DENR and World Bank standards, all parameters are compliant. But it has been observed that the PM10

value for station 4 is quite high, about 190 mg/m3 which maybe caused mainly because of the passing

vehicles during the sampling period. For this period, the parameter measured for dust content in

ambient air is PM-10 since the potential dusts generated from the power plant are coal dust and ash

particles. Based on the data, the ambient air quality on dust is acceptable compared to the standards.

Table 6 summarizes the data for the 1-hour sampling in the second quarter. Sampling location maps are

provided in Attachment 1 while the manual ambient air quality trending graphs from the construction

period up to the present are provided in Attachment 2.

3.1.3. Air Emissions

As one of its environmental features, the power plant has a real-time Continuous Emissions Monitoring

System (CEMS). Parameters for testing include the Total Suspended Particles (TSP), Sulfur Oxide

emissions (SOx), Nitrogen Oxide emissions (NOx), and the Carbon Monoxide emission (CO). Results,

corrected at 6% O2, indicate that emission levels are well within the national and World Bank standards.

These favorable results show that the emissions control of the power plant is highly efficient. Tables 7

and 8 summarize the daily results from April to June 2013 of both units while Figures 6 to 7 shows the

trending graphs of the results in comparison to the standards.

3.2. RA 9275: WATER ENVIRONMENT

3.2.1. Groundwater

Table 9 shows the groundwater monitoring results of the coverage period including that of the previous

periods (Jan 2013 and May 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.

To be noted as before is the Dissolved Oxygen (DO) level of the North Poblacion Deep Well station. The

monitoring result (3.0 mg/L) indicates that the DO level is below that of the given minimum value of DENR

but consistent with the baseline data showing that no significant impact was made. 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

Table 10 shows the marine water monitoring results within the coverage period including that of the

previous period (Jan 2013 and May 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 two storm drains (83 and 140 mg/L). The result is

more than the World Bank Standard but lesser than the DENR standard. TSS may be from silt and other

deposits adhering to the storm drain channels. Regular cleaning of the storm drains will be done to avoid

reoccurrence of high TSS values. 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 afternoon on

June 26, 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.

3.3.3 Naalad Riprapping Update

After a long negotiation with KSPC’s contractor, the land owner has finally given their consent to

work on the riprapping project on their land. According to the owner, the confirmation was

delayed due to the planned river rerouting project of the City of Naga. Currently, KSPC is

coordinating with the city’s contractor for the river diversion to facilitate riprapping at the right

areas. The overall project consists of the following activities:

1. Excavation and dredging

2. Rip rapping

3. Opening of new river route

4. Backfilling

All activities related to opening the new route shall be done simultaneously and must be properly

coordinated. 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 10-12 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 14,140.00 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 bed ash or 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 Geo-Transport in their Ready-Mixed Concrete (RMC) business and CEMEX in their cement

manufacturing business. Table 15 summarizes the industrial and solid waste quantities generated and the

respective disposal methods.

IV. CONCLUSION

Based on the environmental monitoring for the period of April to June 2013, the 2x100 MW Cebu Power Plant

Project has not caused any adverse or detrimental effect to the nearby surroundings. 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. As of the monitoring period, the power plant is in the

operations and maintenance period at full load. Certificates of analyses are in Attachment 3 while Attachment

4 contains the rest of the sampling pictures.
