RSPO CERTIFICATION ASSESSMENT PUBLIC SUMMARY REPORT

Criterion 4.4
Practices maintain the quality and availability of surface and ground water
PTTN has an implemented water management plan, such as : reuse condensate water from Cooling
turbine into Water Treatment, using condensate from steam boiler as water dilution mixing in CPO
processing, minimize water leakages from water pipes in the mill and estates, using dust conveyor
instead of using water for dust collector boiler, installing float switch to all bathrooms. Record of
water using per ton FFB is available, there is reduction from 1.24 m3 water/ t FFB in 2008 to 1.15m3
water/ t FFB in 2010.. BOD Analysis of surface water is tested regularly by SMARTRI laboratory, the
last record dated on 01. 06.2011. The BOD levels and other parameters such as pH must comply with
the local requirements in the Liquid Waste regulations in environmental decree by Province of North
Sumatra . The BOD data are submitted six-monthly in RKL/ RPL to BAPEDALDA (Regional
Environmental Monitoring Body). Checks on records show that all the data complied with regulation.
The auditor team checked that there were installation of chemical traps and oil traps in the mill to
avoid water and soil contamination around the mill. To avoid the contamination of river water, HCV or
riparian zones are in the process of being restored along the river banks. There are several sign
boards of HCV 4.1 to warn people for not hunting and fishing and to remind workers for not applying
fertilizer and pesticides to the palms in the riparian zones – a 50 meter belt along the river banks on
both sides. Palms with red x markings within the riparian zones will not be maintained. No new
palms will be planted in the riparian zones during replanting. SOP HCV monitoring in the riparian
zone has been established and the records is well maintained. PTTN also established SOP agrochemicals
mixing to avoid mixing of agro-chemicals in proximity of water courses, interview with
spraying workers confirmed that they understood the both of the SOPs well.
Compliance Status : Full.

Criterion 4.5
Pests, diseases, weeds and invasive introduced species are effectively managed using
appropriate Integrated Pest Management (IPM) techniques
PTTN has formulated an Integrated Pest Management (IPM) as recorded in “Laporan Sensus”,. PTTN
practiced incorporating cultural, biological, mechanical or physical methods, by :
1. Identification of pests, diseases and weeds before it become an outbreak of maximum level
2. Introducing of beneficial plants for hosts of pests.
3. Introduction Barn Owl (Tyto alba)
4. Planting LCC
5. Frond stacking
6. Minimise use of agrochemicals.
The use of pesticides is minimized through selective spraying instead of blanket spraying for cases of
severe infestation of weeds.. Oil Palm Leaf Eater Control includes detection, cencus, examination,
treatments, evaluation, monitoring and organisation. Checks on records confirmed there was no
outbreak during the last 5 years. Planting beneficial plants, such as Bunga pukul delapan (Turnera
