I. INTRODUCTION
A. Report Purpose and Rationale
1. ADB has agreed to assist the Government of Indonesia (the Government) with technical
assistance (Technical Assistance) for the TA-9082 INO: Preparing the Eastern Indonesia
Sustainable Energy Access Sector Project - Consulting Services (49203-001) by an agreement (the
Technical Assistance Agreement) executed between the Government and ADB. Within the Eastern
Indonesia Sustainable Energy Access Sector Project, the Indonesian state electricity company PT
Perusahaan Listrik Negara (PLN) planning to build 10 to 15 power plants (sub-projects).
2. One core sub-project under the Technical Assistance Agreement is a new Gas Fired Power
Plant Kaltim 2 Peaker which will be constructed adjacent to the already operating Tanjung Batu
Power Plants Complex.
3. Paragraph 53 of the Operations Manual Section F1 / Bank Policies (October 2013), states
that for projects involving facilities and/or business activities that already exist before ADB's
involvement, ADB requires the borrower/client to conduct an environment compliance audit to
determine their safeguard compliance status. The audit by the borrower/client includes on-site
environmental assessments to identify past or present safeguards concerns related to the impacts
on the environment. Where noncompliance is identified, ADB and the borrower/client agree on a
corrective action plan, implementation schedule, and sufficient funds to bring the project into
compliance with the safeguard policy requirements.
4. This environmental DD identifies past and/or present safeguards concerns related to the
impacts on the environment by the operating Tanjung Batu Power Plant Complex (PPC). The
Tanjung Batu Power Plant Complex was not financed or co-finaced by ADB and therefore not
planned or built under consideration of the ADB safeguard regulations. Only national environmental
requirements were considered.
5. The environmental due diligence was prepared based on review of the environmental
impact assessment report for Kaltim Peaker 2, as well as the available environmental monitoring
data of the existing facilities and Addendum AMDAL for Kaltim Peaker 2. During the preparation of
this report, a series of discussions was conducted with the PLN, as well as the UIP IX during site
visits conducted to the Tanjung Batu PPC.
B. Project Location and Scope
6. PLN plans to build a new Gas Fired Power Plant Kaltim Peaker 2 using dual fuel type, a
single cycle gas turbine facility capable of running on natural gas (primary fuel) or HSD
(secondary/backup fuel) to serve peak load (peaking) with a net power output capacity of 100 MW
± 10%. The new Power Plant Kaltim Peaker 2 will be constructed adjacent to the already operating
Tanjung Batu Power Plants Complex (PPC), which consists of the Kaltim Peaker 1 and Tanjung
Batu PP. The gas supply will take place through a new gas pipeline, which will be constructed for
the supply of the existing PPC. Access to the new Kaltim Peaker 2 site is possible on the already
existing access road to the Tanjung Batu PPC. Backup Diesel haulage and storage as well as
water supply and wastewater disposal will use already existing facilities of the Tanjung Batu PPC.
Power evacuation will be done via already existing power lines.
7203F96/FICHT-19385689-v2 3
7. The new project is in principle a duplication of the Kaltim Peaker 1 project and the new site
located directly adjacent to the Kaltim Peaker 1 site within the Tanjung Batu PPC. Therefore the
environmental impacts of Kaltim Peaker 2 will be overlapping with the impacts from the other power
plants within the Tanjung Batu PPC and cumulative impacts must be considered. This is especially
true for air emissions and noise, hazardous waste management, and water consumption and
wastewater releases. These issues have been addressed in detail in the EIA Report for the planned
project, consistent with national laws and regulations as well as international guidelines.
8. Gas supply for Kaltim Peaker 2 will be provided by the gas producer i.e. VICO Indonesia,
through a new gas pipeline (55 Km) from Muara Badak, East of Tanjung Batu. The new pipeline will
use an existing ROW; hence PLN does not need to acquire additional land.
9. Presently all power plants within the Tanjung Batu complex run on HSD, which is delivered
every 4 days by a 6,000 dwt tanker through a jetty on the Mahakam riverbank and stored in fuel
tanks within the complex. The minimum water depth at the jetty is 6.5 m.
10. The proposed project site is located near Tanjung Batu Village, Tenggarong Seberang
District, Kutai Kertanegara Regency, in East Kalimantan Province. The plant site is located south of
the Tanjung Batu PPC, directly bordering the existing Kaltim Peaker 1 in the North. The land for the
planned Kaltim Peaker 2 is owned by PLN and it is uninhabited and unfarmed. PLN started
acquiring land in 1998 on to 2006 for a total of 1,709,190 m2 (171 ha). The official certificate (Buku
Tanah Propinsi Kalimantan Timur Kabupaten) grants PLN the right to build (Hak Guna Bangunan)
on the land for 30 years, i.e., until April 1st 2028. The certificate can be extended in due course.
From these 171 ha, 5 ha will be used for the Kaltim Peaker 2, hence there is no need to acquire
additional land.
11. The existing Tanjung Batu Power Plant Complex presently consists of 2 power plants1:
(i) PLTGU Tanjung Batu i.e. gas turbine combined cycle 60 MW (2x20 MW GT (gas turbine)
and 1x20 MW ST (steam turbine) dual fuel i.e. gas and HSD (high speed diesel). Start of
operation in 1997. However, gas supply declined, hence since 2013 the power plant runs by
using HSD;
(ii) PLTGU Kaltim Peaker 1 (in operation since 17 March 2014 for unit 1, and 18 April 2014 for
unit 2), installed capacity 2x80 MW open cycle gas turbine; COD (commercial operation
date) 2x60 MW, planned as dual fuel. The plant has never used gas and only runs by HSD
since the first operation.
C. Implementation Progress as of September 2017
12. Kaltim 2 Peaker subproject is currently in pre-construction stage with PLN still generating
the necessary permits prior to construction.
13. Total land which has already been acquired more than 10 years ago by PLN is 171 ha:
1 There have been two more small power plants operating at the site but both of them have been taken out of
operation, the last of them in July 2017
7203F96/FICHT-19385689-v2 4
20 ha are fenced with a controlled entrance gate and are presently used as location for 2
power plants including project associated infrastructure (office building, substation, control
room, WWTP, warehouse, canteen etc.);
5 ha will be provided for Kaltim 2 Peaker; and
20 – 25 ha are intended to be used for a PV solar plant.
14. The remaining land within the PLN property is forest (a critical habitat with a small
population of Proboscis monkeys, endemic to Kalimantan), swampland, and secondary bushland.
Human land use and infrastructure comprises PLN housing, school, the access road, non-
permanent houses/shelters and farmland. The farmland is managed by local communities living in
the surrounding of PLN land, with permission from PLN to manage the land.
D. Environmental Categorization, Assessment and Reporting
15. Following ADB’s Safeguard Policy Statement 2009 (SPS 2009) environmentally the Kaltim
Peaker 2 project falls into Category A, mainly because of the project size (100 MW thermal power
plant) and the presence of rare and endangered species in the wider project area, especially
Proboscis Monkeys.
16. An Environmental Assessment and Review Framework (EARF) has been prepared for the
Eastern Indonesia Sustainable Energy Access Sector Project, and an EIA report was conducted for
Kaltim Peaker 2.
E. Institutional Setup and Responsibilities
17. The project executing agency will be the PLN Pusat, which will be responsible for overall
project implementation. The PLN Region (Kalimantan Timur and Utara) will coordinate and
supervise project preparation, while the UIP Kalimantan Bagian Timur IX will be responsible for
supervising procurement and project implementation.
18. The implementing agency will be the PLN Region Kalimantan Timur and Utara, which is
responsible for development of all Power Plants in Kalimantan Timur. PLN Sector of Mahakam is
responsible for project construction, operations management, finance and accounting and
maintenance of infrastructure assets. UIP Kalimantan Bagian Timur IX will be responsible for
coordinating and implementing all project components. PLN Pusat has numerous experiences with
ADB and World Bank projects, and the personnel are familiar with ADB procurement policies and
procedures.
19. The project will be implemented over 2 years from June 2018 to June 2020. The longer
implementation period is due to the fact that this project is linked to the previous Kaltim Peaker 1
project. All procurement to be financed under the ADB loan will be carried out in accordance with
ADB’s Procurement Guidelines (2017).
7203F96/FICHT-19385689-v2 5
II. COMPLIANCE WITH ENVIRONMENTAL SAFEGUARDS REQUIREMENTS AND
IMPLEMENTATION
20. The approach for this due diligence is anchored on consultation and participation of
Regional PLN, UIP IX, and the Executing Agency (EA), as well other community members.
The following data sources and methods were used to set up this DD Report:
(i) One site visit was conducted, together with PLN safeguards officials, PLN – UIP, and the
PPTA environmental team, from 15 - 17 March 2017, to set up this Due Diligence Report.
(ii) Key interviews and discussions were held with staff of Tanjung Batu PP/PLN Sector
Mahakam, process was conducted by staff of UIP Kalimantan Bagian Timur (UIP IX);
(iii) Public consultations were conducted with focus on public acceptance and eventual
complaints against the Tanjung Batu PP activities; village members involved in community
relations were interviewed as well;
(iv) A review of all available project documents was conducted with support from PLN,
especially regarding secondary data and analysis.
A. Monitoring Requirements Based on National Environmental Laws
21. To verify compliance with national environmental requirements, Environmental Management
and Monitoring Reports for years 2014-2016 were used to obtain monitoring results and compare
them with requirements stipulated in the respective national environmental laws and regulations for
the Tanjung Batu Power Plant Complex.
a. Stack Emissions Monitoring Requirements
22. Based on Minister of Environment Regulation No. 21/2008 regarding Fixed Emission Quality
Standards for Thermal Power Plants, the required parameters to be monitored are SO2, NO2, TSP,
opacity and CO. Monitoring parameters and locations are presented in the following tables.

b. Monitoring Requirements for Ambient Air (24 hours)
23. According to Government Regulation No. 41/1999, National Quality Standards for Ambient
Air, values of SO2, NO2, TSP and CO are required for monitoring. Due to the usage of diesel at
Tanjung Batu Power Plant, carbon monoxide emission was monitored as well. Ambient air
*) cooling water blowdown streamed to the WWTP **) if phosphate injection
7203F96/FICHT-19385689-v2 8
29. Required monitoring frequency is once per month at the discharge point of the PLTGU
Tanjung Batu.
30. Monitoring of wastewater temperature is not required according to the existing permit, thus
regular measurements regarding effluent temperatures were not conducted. However, in 2017
the Tanjung Batu PP operated occasionally, and temperature tests from the outlet of the condenser
(warm wastewater) were made. These measurements showed that the wastewater temperature
was up to a maximum of 38°C. The maximum national standard of temperature for wastewater
releases is 40°C (Minister of Environmental Regulation No. 8/2009, regarding Wastewater Quality
Standards of Thermal Power Plants).
e. Hazardous Waste of PLTGU Tanjung Batu
31. Management of hazardous waste at Tanjung Batu PP is regulated based on the Hazardous
Waste Temporary Storage Permit No: 660.1/43/BLHD/III/ 2015, for PLN Regional East Kalimantan,
Mahakam Sector, Tanjung Batu PLTGU, Building/warehouse dimension: 7 x 10.70 m2.
32. The expire date of this license was 30 March 2017, but according to a notification letter from
the Environmental Agency to PLN Tanjung Batu the Hazardous Waste Temporary Storage Permit
has been extended.
B. International Guidelines
a. Air Emission Limits
33. The International Finance Corporation (IFC, World Bank Group) defined guidelines for the
emissions of facilities producing more than 50 MWth using combustion engines and combustion
turbines (Table 7).
Table 7: IFC emission guidelines for facilities larger than 50 MW with combustion turbines and combustion engines (IFC, 2008)

b. Air Quality Standards
34. The Air Quality Standards are defined according to the different levels of hazard that the
pollutants pose depending on the exposition period. This way, the standards are defined for
different time frames, allowing the protection against the short term acute impacts, the medium
term impacts and the long term impacts.
35. IFC states that emissions from projects shall not result in pollutant concentrations in the
ambient air that reach or exceed the relevant ambient air quality guidelines and standards by
applying the national legislated standards or, in their absence, the World Health Organization
(WHO) Guidelines or other internationally recognized sources like the U.S. EPA (United States
Environmental Protection Agency) or the European Council Directives (ECD). The World Health
Organization (WHO) Guidelines for averaging period of 24 hours are given in Table 8.

c. Noise Level Guidelines
36. This section addresses noise level guidelines beyond the property boundary of the facilities
according to the IFC General EHS Guidelines. Noise impacts should not exceed the levels
presented in Table 9, or result in a maximum increase in background levels of 3 dB at the nearest
receptor location off-site.

d. Wastewater Guidelines
37. Effluent guidelines are applicable for direct discharges of treated effluents to surface waters
for general use. Guideline values for process emissions and effluents in this sector are indicative of
good international industry practice as reflected in standards of countries with recognized
regulatory frameworks. These levels should be achieved, without dilution, at least 95 percent of the
time that the plant or unit is operating, to be calculated as a proportion of annual operating hours.

C. Monitoring Results
a. Results of Air Emissions Monitoring
Tanjung Batu Gas Turbine Combined Cycle - 60 MW
38. Fichtner had access to emission data for this plant for the years 2014, 2015, and 2016. It is
known that the plant operates exclusively with HSD since 2013, and that in the second semester of
2015 only one turbine was operating.
39. HSD with 1.2% of sulfur (S) has been assumed to be used. The IFC EHS Guideline for
Thermal Power Plants (2008) states up to 1.0 % S for non-degraded airsheds, and up to 0.5 % S
for degraded airsheds. The characteristics of the HSD have been discussed in the Feasibility
Study for the Kupang Peaker 1, to be built in the Nusa Tenggara Timur Province. It is assumed
that the same HSD type will be used throughout the country.
40. The emission data show that the national emission limit values are respected, but that the
international ones regarding the amount of sulfur (S) in the fuel and the concentration of emitted
NO2 are not.

Kaltim 1 Gas Fired Power Plant - 100 MW
41. Fichtner was given access to emission data for the existing Kaltim Peaker 1 (Table 12).
Data which were not made available have been estimated based on available technology and on a
combustion calculation. As a basis for the combustion calculation, HSD with 1.2% of sulfur (S) has
been assumed to be used. The characteristics of the HSD have been consulted in the Feasibility
Study for the Kupang Peaker 1 Plant, to be built in the Nusa Tenggara Timur Province. It is
assumed that the same HSD type will be used throughout the country.
42. All monitoring parameter concentrations are below the national and the international
emission limit values applicable, with the only exception of the maximum amount of S in the fuel,
following international standards.

46. As can be noticed in Table 14, minor exceedances of the national and international limits in
2014. However, results show neither exceedances of the national nor the international limit in the
following years.
d. Results of wastewater monitoring
47. The summarized wastewater monitoring results are shown in Table 15 and Table 16 as
averages for the year 2016. All values are in compliance with national requirements, however a
near-exceedance of international limit value of iron content can be observed in March, and one
exceedance in June. According to the monitoring results, free chlorine is not present in the
monitored wastewater.
48. Monitoring of lead, cadmium, mercury and arsenic was not required for the fulfillment of
national legal requirements, thus not performed. As most of the wastewater infrastructure is made
of steel these substances are not expected in the wastewater effluents.
