I. EXECUTIVE SUMMARY
1. This Initial Environmental Examination has been prepared for the Rural Infrastructure
Rehabilitation of New-Eden – Concepcion Access Road and Foot Trails. This Sub-project is
the rehabilitation of the existing access road with an estimated length of 5.260 km, width of 4
m. The main proponent of the project is the Local Government Unit of Pangantucan, Bukidnon
assisted by Department of Environment and Natural Resources – Integrated Natural
Resources and Environmental Management Project. The project implementation will be co-
managed by the Municipal Planning and Development Coordinator and the Municipal
Engineer.
2. The objective of the Rural Infrastructure – Rehabilitation of New-Eden – Concepcion
Access Road and Foot Trails is uplifting the quality of life of the people thru the provision of
all-year-round easy and affordable access thereby improving the prompt delivery of basic
services, increasing economic opportunities and conditions. The proposed access road and
foot trails will support the NRM project activities of the constituents.
3. The Sub-project has been categorized by ADB as Environment Category B and this
IEE was prepared consistent with the environmental assessment requirements of ADB’s
Safeguard Policy Statement of 2009. The IEE was carried out through screening and analysis
of various environmental parameters, field investigations, stakeholder consultations, and
review of other road project reports in the Philippines. The IEE covers the general
environmental profile of LGU-Pangantucan rural infrastructure sub-project and includes an
assessment of the potential environmental impacts during different sub-project phases and
formulation of corresponding mitigation measures. The IEE was prepared by the LGU-
Pangantucan with the cooperation of RPCO, PMU, WMCO and POs.
4. The total cost of the subproject is Nineteen Million Two Hundred Six Thousand
Seven Hundred Sixty Pesos and Sixty-nine centavos (PhP 19,206,760.69). The project
funding source is majority coming from the DENR - INREMP and LGU with a cost sharing of
80% and 20%, respectively. It will be assumed that the benefits of the subproject will be the
reduction of travel time by 15 minutes, transportation cost by 21.58%, increase number of trips
by 50% and availability of infrastructure support for NRM projects and other agricultural
livelihood projects of the community.
5. Major land use along the road access and foot trails rehabilitation subproject is
agriculture which is part of production forest. The middle section of the proposed subproject
is located along the Mt. Kalatungan buffer zone.
6. The IEE, based on the screening of baseline environment and review of proposed civil
works, has not identified any major environmental concerns due to proposed rehabilitation of
New-Eden – Concepcion Access Road and Foot Trails given that all the proposed civil works
are only asset preservation of existing roadway and are located within existing right of way.
There will only be localized short-term impacts during construction activities due to
implementation of civil works that will be addressed in the detailed design and through
implementation of the mitigation and monitoring measures specified in the environmental
management plan. The IEE process included stakeholder participation and consultation to
help LGUs achieve public acceptance of the Sub-project. A series of consultations with its two
influenced
1
7. Barangays (Concepcion and New Eden) of the local government of Pangantucan
confirmed that the rehabilitation of New-Eden – Concepcion Access Road and Foot Trails is
essential for economic development.
8. A grievance redress mechanism will be established by the LGU of Pangantucan prior
to commencement of site works to ensure that complaints of affected persons and other
stakeholders regarding the project’s environmental performance are promptly addressed.
9. The IEE includes an environmental management plan which details the mitigation
measures, environmental monitoring activities, institutional responsibilities, and environmental
management capacity building. The LGU through its Municipal Planning and Development
Coordinator and the Municipal Engineer will ensure that relevant EMP provisions are included
in bid and contract documents for detailed design, project supervision and civil works. During
construction, they will closely conduct monitoring the contractor’s environmental performance
and over-all EMP implementation. Semi-annual environmental monitoring reports will be
submitted by LGU to ADB and such reports will be posted on ADB’s website for public
disclosure.
10. The major positive impact of the project will be economic and better accessibility. The
sub-project will directly benefit people located within the two barangays providing improved
access and economic development. In relation to the National Greening Program, the
proposed road will traverse these NGP areas. The sub-project would also benefit the
environment in terms of reduced soil erosion and landslides through slope stabilization
measures and construction of retaining structures. Dust generation from the damaged roads
will be reduced by the improvement of pavement. Health risk to the roadside communities and
damage to the biological environment will be reduced due to pavement improvement and soil
erosion control measures.
11. This Subproject will have overall beneficial impact and will have minor negative
impacts that will be carefully monitored and adequately mitigated through implementation of
the EMP.

III. DESCRIPTION OF THE PROJECT
A. Overview
17. Barangay New Eden and Concepcion are adjoining barangays along the foot of Mount
Kalatungan and head water of the Muleta River Watershed. These are rural and farming
barangays. The New Eden-Concepcion road is an existing access road that traverses along
these two (2) barangays leading to Poblacion.
18. Rehabilitation of New Eden-Concepcion access road and foot trail will greatly improve
the accessibility within these two (2) barangays. It could also provide alternative route to
farmers in marketing their products to other barangays or bringing those products to
Poblacion. It will also ensure safety of the people due to the ease of access for responding
personnel in case of emergencies. As entry point to Mt. Kalatungan climbers, this particular
access road and foot trail is also very useful for eco-tourism endeavours, as part of the Eco-
tourism program of the municipality (Mt. Kalatungan being Ancestral Domain of the Manobo
and Talaandig Tribe), there is a partnership between the LGU and various Indigenous Peoples
(IPs) in the area, as provided for by Ordinance No. 16, series of 2014. Particularly, the IPs
serve as tourist guides, and porters, earning an income of 350 and 400 per day, respectively
(ratio of 1:10 guide:tourist).
19. To boost economic activity and improve social and infrastructure services in the rural
barangays, particularly for Concepcion and New Eden, and the municipality as a whole, the
rehabilitation of New Eden-Conception access road and foot trail is deemed timely and
necessary to generally lessen the vulnerability of the barangay residents during emergency
situations.
20. The Rehabilitation of New-Eden – Concepcion Access Road and Foot Trails is the only
existing road directly linking the Barangay New-Eden and Concepcion. Currently, residents
from Barangay Concepcion will pass through first barangay Poblacion before reaching
Barangay New Eden and it will take them a travel distance of 12.5 km. While using the
proposed road section that is directly connecting Barangay Concepcion and Barangay New
Eden only take 5.26 km which have a difference of 7.24 km travel distance.
21. Among all road networks of the municipality, this said road section has the worst
condition in terms of its physical condition and accessibility compared to other road section
within the municipality. The two (2) barangays within the influence area of this road section
have large volume of agricultural products such as high value crops and vegetables. To
provide ease in transporting these said agricultural products to the market, this road section
needs to be given due attention, consideration and priority.
6A. Project Location
22. The Municipality of Pangantucan is situated along the southwestern border of the
province of Bukidnon. It lies within 124° 40’ to 124° 50’ east longitude and 7° 35’ to 7° 55’
north latitude, bounded on the north by the Municipalities of Valencia and Talakag, on the east
by the Municipalities of Maramag, Don Carlos and Kadingilan, on the west by the Municipality
of Kalilangan, and on the south by Province of North Cotabato. It is approximately 75 km
southwest of Malaybalay City, the capital of Bukidnon Province, and is about 166 km southeast
of Cagayan de Oro City, the capital of Region 10 (Northern Mindanao). It is composed of 19
barangays, all of which are accessible all year round.
23. Pangantucan has a total land area of 485.84 sq km (48,584 ha), of which, about 52%
is currently classified as forestland; the remaining 48% are Alienable and Disposable (A and
D) lands.
24. The Municipality’s terrain is characterized by slightly undulating and rolling upland
areas, about 62% of which has rolling or hilly terrain within 18% to 50% slope range. Only
about 14% of the land area is suitable for agricultural production. On the northwest portion of
the municipality is Mt. Kalatungan, the second highest peak in the province with an elevation
of 2,824 m asl. Its mountain ranges occupy about 21% of the municipality’s total land area.
B. Project Rationale
25. The Muleta River Watershed is found in the southern portion of the province covering
the municipalities of Pangantucan, Don Carlos, Kitaotao, Dangcagan, Kibawe, Kadingilan and
Damulog (Figure 1). It is one of the important tributaries of the Pulangi River, which flows
southward. It will join the Pulangi River in the boundary of Bukidnon and Cotabato province.
The municipality has many water sources with their headwaters from Mt. Kalatungan. Water
resources along Mt. Kalatungan vicinity are of critical importance to both natural ecosystem
and human development. It is essential for agriculture, industry, and human existence. The
healthy aquatic ecosystem is dependent on the physicochemical and biological
characteristics. The quality of water in any ecosystem provides significant information about
the available resources that support life in that ecosystem.
26. Barangay Concepcion and New Eden are located at the southern foot of the Mt.
Kalatungan National Range Park and head water of the Muleta River watershed. The influence
area of the proposed RI subproject has farmlands that are cultivated for agricultural crops.
Thus, the rehabilitation of the road section will be beneficial to the farmers, and will be easier
for them to transport their farm products.
27. Additionally, DENR programs such as INREMP NRM subprojects, and NGP, are
located within the influence area; and this proposed rural infrastructure will be a support facility
to such DENR subprojects. The Indigenous People Organization (IPO), which is the Portulin
Talaanding Tribal Association Inc. (PTTAI), is a recipient of several DENR programs and are
also farmers who are actively engaged in farming within the area.
28. Overall, there is a great need to rehabilitate the said road section, in order that the
travel time going to the farms will be shortened. Constituents will be encouraged in farming
since it will be easier for them to transport their farm products to the market, at a lesser
transport cost.

1. Project Components
29. The scope of works of the road rehabilitation subprojects are the following:
Road graveling
Road concreting
Provision of stone masonry line canal
Provision of RCPCdrains
Provision of riprap stone masonry soil stabilization
Concrete slab for foot trail
30. The 2,850 meters surface gravelling in Barangay New Eden will start from Sta. 00+000
to station 0+600 and Station 1+200 to Station 3+000. The average thickness of surface
aggregate to be placed shall be 0.20m on the existing 4 meter-wide barangay road. Placing
of surface aggregates shall conform to the requirement of the road during the construction
date to achieve standard road level and stability.
31. The station 0+600 to station 1+200 requires road concrete pavement because it is mostly
rolling with some critical sections. The average thickness of surface to be placed shall be 6
inches or 150mm on a 4 meter-wide barangay road and 600 meters.
32. Provision of stone masonry line canal from station 0+00 to station 0+600, station 0+600
to station 1+200, station 1+700 to 2+000, station 2+100 to station 3+050, station 3+150 to
3+450.
33. The installation of RCPC Cross Drainage at station 3+580 t0 3+600, station3+660 to
3+675, station 3+700 to 3+720 will be made-up of Reinforced Concrete (RC) and stone
masonry.
34. Provision of riprap stone masonry is necessary for slope protection in the site

102. Description of the Project Phases
a. Pre-Construction Phase/Pre-Development Phase
37. This phase would involve the social preparation (to include organizational
strengthening, planning, identification and prioritization of community needs) of the community
for the entry of the project to the site, conduct of pre-engineering activities covering detailed
survey works to determine alignment of roads and canal systems, preparation of the detailed
engineering plans and programs of work, ROW negotiation, recruitment of work force and
initial sourcing and procurement of construction materials. These activities will be conducted
by the proponent technical staff, partner line agencies, NGO service providers, community
beneficiaries especially the Indigenous People and contractors.
b. Construction/Development Phase
38. This phase would involve the mobilization of construction equipment, construction
workers and materials to the specific subproject site after which the longer period of actual
construction work will commence. The construction phase will end up with the demobilization
of construction equipment, workers and other construction paraphernalia from the construction
site. Majority of these activities will be undertaken by the contractor and community
beneficiaries under the close supervision of the SPMU most especially by the municipal
Engineering Unit.
c. Operation Phase and Maintenance Phase
39. This phase involves the actual maintenance of the rehabilitated access road during its
expected economic life. Monitoring tools and parameters will be set forth in the MOA that the
LGU and DENR will sign to ensure sustainability of the constructed facility. The specific
monitoring items and parameters, location and frequency, monitoring responsibilities and
sources of budget are presented in the EIAMMP as attached.
d. Abandonment Phase
40. This phase is included in the project demobilization. The proponent does not intend to
abandon any facilities and unserviceable equipment used during construction. The project
location will not be abandoned in disorderly condition but instead restored for functional use.
Following the completion of the construction, the proponent will dismantle temporary shelters
and the construction yard including unserviceable vehicles and equipment.
41. Wastes arising from the abandonment are expected to be minimal. These wastes could
include small volumes of left over sand and gravel, re-bars and other construction materials
and lumber.
D. Manpower Requirements
42. Construction activities will require hiring of skilled and unskilled manpower. It is
assumed that some skilled, semi-skilled and unskilled manpower will be available in the area.
Skilled manpower not available in the locality may be sourced from other nearby localities.
Technical manpower will be a complementation of specialists to be provided by locally known
engineering firms.
1143. During the construction phase, a workforce consisting of contractual and regular
laborers will be employed to carry out the construction of the proposed project.
44. The Contractor shall employ qualified and sufficient staff to carry out inspections,
testing and monitoring for the project.
E. Project Cost
45. The propose RI project has a total cost of Nineteen Million Two Hundred Six
Thousand Seven Hundred Sixty Pesos and Sixty-Nine centavos (PhP 19,206,760.69).

RI Subproject Milestones53. Barangays Concepcion and New Eden are located at the Southern foot of the
Kalatungan National Range Park and head water of the Muleta River watershed.
54. Barangay Concepcion’s land area is about 2,719 hectares. The types of soil is from
sandy to clay. It is bounded by Talakag in the North, Poblacion and Adtuyon in the South,
New Eden in the East, and Mendis in the West.
55. Barangay New Eden has a total land area of about 1,015 hectares. Based on soil
texture distribution of the barangay, about 10% are clay, 44% are loam, 5% are sandy, 19%
are clay loam and 22% are sandy loam. The barangay is about 7 km from the central Poblacion
of Pangantucan. It is bounded in the north by the municipality of Talakag, in the south by
barangay Adtuyon, in the east by barangay Portulin, and in the west by barangay Concepcion.
A. Elevation and Slope
56. The municipality of Pangantucan has about 21% are mountain ranges, while about
61% are hilly or rolling terrain. The remaining area is relatively flat, fit for agricultural
production. The elevation of Pangantucan ranges from 252 m to 2,824 m above sea level (m
asl) with the highest point at the peak of Mt. Kalatungan. Around 40% of the area has an
altitude of 1,000 m especially, within the Mt. Kalatungan range. The rest of the area lies within
the 252 to 1,000-meter altitude.
57. The terrain of Pangantucan is characterized by slightly undulating and rolling upland
areas (Table 5). Only 4.81% of the total area is relatively flat, with slope-range of 0 to 3%. A
large portion of the land, however, has slopes ranging from 18% to 50% and above.

58. In particular, the proposed subproject has an elevation ranging from 1,005 to 1,243 m
asl with an average slope of 9.6%. Other details are shown in Figure 2.
14Figure 2: Elevation and Slope of the Proposed Subproject
B. Geology
59. Based on the Geologic Map of the Philippines and the Geologic Report of
Pangantucan, Bukidnon prepared by Francisco et al. (1952), the rocks underlying the area
arranged in their order of decreasing age are the limestone, Pangantucan volcanic and the
clastics.
60. The limestone is believed to be in the upper Mio-Pliocene age and considered as the
oldest in the stratigraphic sequence. It is coralline and in places highly fossiliferous. It is well
bedded, hard and locally marl and thin interbeds of calcareous sandstone and shale are
observed. Sinkholes are common.
61. The Pangatucan volcanic, a terminology proposed by Francisco (1952) to indicate the
type of locality where the volcanic were encountered is porphyritic and in part, amygdaloidal.
The penocrysts consists of feldspar, olivine and in minor amounts, of stubby crystals of
pyroxene. The groundmass consists of fluidal microlites of feldspar mixed with magnesite and
granule of pyroxene with intercalated glass occasionally chlorite. Amygdulesare filled with
chlorite. This rock is exposed over a wide area though partly covered with either thin alluvial
or residual mantle mostly on the lower slopes.
62. The limestone and the widespread volcanic are uncomfortably overlain by the clastics
composed essentially of sandstone and mudstone with interbeds of diatomite lenses. The
sandstone is made up mostly of quartz grains small amount of minerals, possibly horrnblende,
augite and magnetite. The mudstone is light gray carbonaceous and some are mixed with
diatomite.
15C. Soil
63. Generally, the soil of Muleta Watershed consists mostly of Adtuyon clay Kidapawan
clay, Macolod clay and mountain soil (Table 6). Adtuyon clay has the largest area coverage.
Its coverage encompasses middle portion of the watershed where six municipalities are
situated. On the other hand, the sub-watersheds are characterized by Kidapawan clay except
for Apulang River in southwestern portion where the soil type is Macolod clay.
64. All these series were developed from parent materials that originated from the volcanic
lava. These types of soils are called zonal soils owing to the combined effects of climate and
vegetation on various rocks which have lived in a well-drained position long enough for
dynamic equilibrium to be reached between the delay and accumulation of organic matters
and between the rates of erosion and rock weathering.

D. Water quality
65. The proposed rural infrastructure subproject is the rehabilitation of New Eden –
Concepcion access road and foot trail which is located at Barangay New Eden and Sitio
Tagolilong, Barangay Concepcion, Municipality of Pangantucan, Province of Bukidnon. The
Barangay is one of the beneficiaries of the Integrated Natural Resources and Environmental
Management Project for the municipality since the Muleta River traverses the barangay
boundary. The proposed access road and foot trail will link to municipal watershed subprojects
since the RI subproject will start at the municipal boundary of Maramag, Don Carlos,
Kadingilan and Valencia which is the Muleta River.
66. In addition, the proposed access road subproject is passing across the Pulangi river
which is one of the tributaries of the Muleta Watershed. The Pulangi river has still no water
classification pursuant to DAO No. 34, Series of 1990 and DENR Memorandum Circular No.
09, Series of 2001. In the absence of water classification and in accordance with the Manual
of Procedure for Water Classification, the Pulangi river is assumed to be a Class A waters
since most of the upstream stations are under this classification. A “Class A” waters intended
beneficial use is public water supply class which is usually sources of water supply that will
require complete treatment (coagulation, sedimentation, filtration, and disinfection) in order to
meet the National Standards for Drinking Water.
67. The Watershed Management Plan (2015) described the water quality conditions of the
Muleta Watershed which was based on DAO 34-1990. The description is only limited to the
following parameters:
The Muleta Watershed mean temperature is 27°C which indicates that the water
in the watershed is within the normal range for surface water.
16 Average pH value of 8.4 taken from different monitoring points showed that the
water quality of Muleta watershed conformed to the set standard (6.5 – 8.5) as
pH is an important limiting chemical for aquatic life.
Biochemical Oxygen Demand (BOD) in Muleta watershed has an average value
of 1 mg/L and still within the set standard (5 mg/L), which means minimum
degree of pollution strength of domestic and industrial wastes or has low in
purification capacities of bodies of waters in receiving organic wastes.
Dissolved Oxygen (DO) levels range from 5.5 to 7.7 mg/L - ) which is still above
the minimum set standard for Class A water (minimum of 5 mg/L.
Phosphate level of the Muleta Watershed is about 0.30 mg/L which is above the
set standard (0.1 mg/L).
The fecal coliform based on the existing monitoring station in the Muleta watershed
is 780 MPN/100 mL which is higher than the set minimum standard of 100
MPN/100 mL.
E. Land Classification
68. Pangantucan has a land area of about 48,584 ha, which is the 9th largest among the
20 municipalities of Bukidnon and two (2) cities of the province. Of the total land area, about
53% or about 257.57 ha is currently classified as forestland, while about 47% or 228.27 ha is
A and D lands.
69. About 29 % of the 53 % of forestland, is a production area, where DENR subprojects
are located, such as; National Resources Management (NRM), Reforestation, and National
Greening Program (NGP), where the communities are the direct beneficiaries.
70. Barangay Concepcion has a total land area of about 2,673 ha, and about 97% or about
2,598 ha is classified as forestland, and about 3% or 75 ha is classifies as A and D (Table 7).
Barangay New Eden has a total land area of about 947 ha, 60% or 567 ha is classified as
forestland, and about 40% or about 380 ha is classified as A and D. Table 2 shows the land
area by barangay per classification.
71. It must be noted that the proposed road access rehabilitation in Pangantucan is within
the public land as shown in Figure 3. In addition, the proposed subproject does not fall within
the Protected Area or Special Area for Protecting Biodiversity of the Mt. Kalatungan Range
Natural Park. The subproject covers about 5.0 km, wherein the length of the foot trail for
proposed rehabilitation is only 1.81 km. As shown in Figure 4, only about 80 m of the said foot
trail runs along the edge of the Buffer Zone. Hence, the LGU of Pangantucan has requested
a certificate to the Protected Area Management Board of the DENR Region 10 that the access
road and foot trail to be rehabilitated under INREMP, have long been in existence and needs
to be improved for efficient protection and monitoring purposes (Appendix 1).
F. Land Cover and Land Use
72. Table 8 shows the distribution of major land use by municipality within the watershed.
In terms of annual crops, the Don Carlos has the biggest area coverage (5,023 ha) while
Damulog has the smallest area (864 ha). Closed forests are locally found in Pangantucan,
Valencia and Talakag.
