Apat’ terjadi lagi di Batang Rajang

SIBU: Fenomena longgokan sisa-sisa kayu yang ‘membanjiri’ sungai Batang Rajang bermula dari Ulu Baleh sehingga ke kawasan Kapit, Song, Kanowit, Sibu dan seterusnya ke kawasan hilir yang lain kini terjadi lagi.

Juga dikenali oleh penduduk setempat sebagai ‘apat’, ia dipercayai berlaku disebabkan oleh aktiviti pembalakan yang tidak terkawal di kawasan Ulu Baleh.

Ini menyebabkan sisa-sisa kayu dan pokok daripada aktiviti pembalakan itu jatuh ke sungai disebabkan hakisan tanah yang kemudiannya dibawa arus sungai apabila berlakunya hujan dan air pasang besar.

Rentetan itu, kejadian yang dianggap sebagai fenomena alam disebabkan sikap manusia telah memberikan impak kepada ekosistem sungai dan masyarakat yang masih menggunakan sungai sebagai pengangkutan utama mereka.

Lebih teruk lagi apabila seluruh Kapit mengalami gangguan air seperti notis yang dikeluarkan oleh Jabatan Bekalan Air Luar Bandar (JBALB) pada hari ini.

Timbalan Ketua Menteri yang juga Adun Baleh Tan Sri Datuk Amar Dr James Jemut Masing turut melahirkan rasa kesalnya terhadap kejadian ini.

Beliau berkata, setelah kali pertama berlaku pada 2010 di Batang Baleh iaitu salah satu cabang Sungai Batang Rajang, ia kini berlaku lagi dengan serius.

“Ini menjejaskan pergerakan penduduk yang tinggal di sepanjang Sungai Baleh,” katanya.

10 tahun berlalu ...
tahun ni terjadi lagi ...

ini antara apa yang terjadi 10 tahun dulu ... selepas bertimbun2 kayu hanyut ... penduduk tempatan d kejut kan dengan kejadian ikan2 yang kelemasan ... timbul d permukaan air ...


dan ni antara berita yang FC dapat cari dari 10 tahun lepas ...

KUCHING: Selepas dikejutkan dengan fenomena luar biasa sisa balak dan kayu terapung di Sungai Rajang, sejak Khamis lalu, penduduk yang tinggal di tebing sungai terpanjang di Malaysia itu sekali lagi dikejutkan dengan kejadian luar biasa, kelmarin. Kali ini, bukan sisa kayu terapung yang membuatkan perhatian terarah ke sungai yang mengalir deras itu, tetapi ribuan ikan air tawar termasuk patin, labang, jelawat dan kaloi yang timbul di permukaan dipercayai mabuk akibat lumpur tebal yang memenuhi sungai berkenaan. Keadaan itu menyebabkan penduduk di tebing Sungai Rajang bagaikan berpesta, menangkap ikan mabuk itu yang ada antaranya mencecah berat sehingga 20 kilo gram seekor. Seorang penduduk di pekan Kanowit, Boniface Endawi Kana, 45, berkata fenomena luar biasa ikan timbul itu disedari penduduk yang menyusuri sungai itu selepas ribuan tan sisa kayu terapung melalui pekan berkenaan.

“Apabila menyedari ratusan ikan timbul, penduduk bergegas mendapatkan perahu dan mengutip ikan yang belum mati itu sehingga akhirnya keadaan di Sungai Rajang yang sebelum itu sunyi tanpa sebarang aktiviti selepas dilanda fenomena sisa kayu hanyut, bertukar menjadi pesta menangkap ikan mabuk.

"FENOMENA ANEH PADA 8.10.2010 DISUNGAI RAJANG,SIBU"

Masihkah anda ingat pada 8.10.2010? Sungai Rajang pernah dilanda sebagai sesuatu yang luar biasa dan aneh apabila himpunan kayu yang dihanyutkan arus sungai berpuluh-puluh kilometer panjangnya menyusuri Sungai Rajang.

Kejadian aneh itu mula kelihatan sekitar jam 2 petang dan sekitar jam 4 petang keadaan kayu-kayu dihanyutkan arus semakin bertambah. kesemua bot exspres yang bertolak dari Kapit ke Nanga Gaat dan Putai terpaksa berpatah balik ke Kapit ekoran laluan sungai langsung tidak dapat dilalui. Beberapa bot exspress yang bertolak dari Sibu ke Kapit terpaksa memperlahankan kelajuan bagi mengelak terlanggar kayu dan ada juga bot yang terperangkap dicelah-celah himpunan kayu hanyut dan amat susah untuk begerak.

Sehingga jam 5 petang, tebingan sungai Sibu masih dipenuhi penduduk tempatan yang keluar beramai-ramai menyaksikan fenomena aneh yang tidak pernah berlaku. Kemungkinan fenomena tersebut berlaku disebabkan beberapa faktor seperti hujan yang turun lebat tanpa henti di Hulu Baleh serta kemusnahan ekologi alam disebabkan aktiviti pembalakan yang berleluasa.

Media Statement- Logjam at Baleh River


KUCHING

23 AUGUST 2021

Sarawak Energy strongly refutes claims that the logjam and debris situation seen at Baleh River is caused by site clearing works from the Baleh Hydroelectric Project (HEP).

Scheduled for completion in 2026, the 1285MW Baleh HEP is a key State Infrastructure project. It is in the interest of Sarawak Energy to ensure that such incidents do not occur at the Baleh project site as it is detrimental to the safety of our people, our neighbouring communities and the hydropower facilities and will affect the timely completion of the project.

There is no major land clearing activity currently happening at the project site that would have contributed to the situation.

The last site clearing works was in 2018 during project commencement and that was downstream from the diversion tunnels. The activity was completed in April 2019 where the associated logs and debris were properly disposed off in accordance with the approved Natural Resources and Environment Board (NREB) guidelines and under their supervison.

The origin of the logjam and debris is upstream of the project site and is clearly not from the site clearing works. This is because biomass clearing activities upstream of the dam to prepare for impoundment is only expected to start in 2023 which is in two years time.

These biomass clearing activities will be under a structured waste management program under the supervision of the NREB in compliance with the requirements of the Baleh HEP Social Environment Impact Assessment (SEIA) report approved in 2015.

To verify the source of the floating debris, Sarawak Energy’s team onsite has conducted land, river and aerial drone surveillance following reports of the mass accumulation of timber and other natural debris in the river.

From the initial assessment, it has been concluded that the source of the debris is more than 1.5km upstream of the diversion tunnels inlet portal. It is understood that timber logging continues to be active at upstream tributaries of Baleh River.

Sarawak Energy is deeply concerned about the impact of the logjams on the safety of the construction of Baleh HEP. If the situation continues, there will be a significant risk to the project’s construction as well as the safety of downstream communities.

Sarawak Energy’s team has already started trial clearing works to determine the safest and most efficient method to clear the floating timber debris obstructing the water flow into the inlet portal of the diversion tunnels. For safety reasons, the pace of the clearing works can only be accelerated after the high water levels recede.

Sarawak Energy reiterates its committment to the responsible delivery and environmental performance of all projects to comply with Sarawak and Malaysia laws as well as international standards and guidelines.

Baleh HEP is developed in line with international best practices for large dams to ensure integrity and safety. These guidelines include:

• International Commission on Large Dams (ICOLD) standards and guidelines which ensures our hydropower projects are built and operated safely.

• International Hydropower Association (IHA) Hydropower Sustainability Assessment Protocol (HSAP) which is formally embedded in our project development process.

As a member of the IHA, Sarawak Energy is building the Baleh HEP in accordance with the HSAP in which environment control is a key component and requisite.

This is reflected in the preparatory works, detailed geological investigations and studies conducted at various stages of hydro project development.

Independent reviews are also conducted throughout construction, before impoundment and periodically during operations following commissioning. This has been the practice since the development of Batang Ai Dam, Sarawak Energy’s first large hydropower project, which was constructed in the 1980s and comminssioned in 1985.

Sarawak Energy calls on all agencies, other stakeholders and operators in the area to work together to resolve this issue which presents a threat to the safety of the Baleh River community and the safe and timely delivery of the Baleh HEP.
