Ashalim Creek (Nahal Ashalim) Incident

On June 30, 2017, ICL Rotem, a subsidiary of ICL located in Israel’s Negev region, experienced a significant environmental incident in which approximately 100,000 cubic meters of acidic phosphogypsum liquid were released into the surrounding environment as a result of a breach in a detainment pond. The liquid entered the nearby Ashalim Creek (Nahal Ashalim), a dry riverbed that leads from the vicinity of the Rotem Industrial Zone to the Dead Sea. Ashalim Creek flows through an area designated as a nature reserve, managed by the Israel Nature and Parks Authority (INPA). The incident has since been under investigation led by Israel’s Ministry of Environmental Protection. The Company is taking action to rectify environmental impacts caused to the Ashalim Creek and its surrounding area. \

The Company took immediate action to stop the flow out of the breached pond, in full coordination with the Ministry and the INPA. ICL worked closely with the various authorities in the region, primarily under the direct instructions and supervision of the INPA. Coordination and continued follow up of restoration activities are being conducted by ‘HaMaarag’ (Israel’s National Ecosystem Assessment program).

The initial focus was on providing immediate relief to reduce the environmental impact on wildlife and vegetation along the path of the flow. Activities included a massive operation to pump out water holes along the dry river bed where liquid collected. The liquid was then transported back to ICL Rotem for treatment. In parallel, ICL is cooperating with the ongoing investigation.

Concurrently, arrangements were made to irrigate impacted trees and transport potable water, as well as to create alternative drinking spots for the wildlife population in the region. In addition, various monitoring schemes were established by the INPA to monitor soil, water and vegetation.

Mitigation efforts were also taken at the lower reaches of Ashalim Creek near the Dead Sea where the flow collected in the Ashalim reservoir as well as in an abandoned ICL quarry that has since been developed into a small saltwater wetland, known locally as “Swan Lake”. ICL conducted a range of detainment, diversion, monitoring and neutralization operations in these lower reaches of the Ashalim Creek. While some damage to the wetland was observed in the immediate months following the incident, a year later most of the vegetation has recovered.

Following the incident, the INPA closed the nature reserve to the public. However, during the 2017-2018 rainy season, there were two major rain events that caused the Ashalim Creek (Nahal Ashalim) to flow vigorously. Measurements taken following that rainy season by the INPA have indicated a significant improvement to environmental parameters of the creek. The Ami-Az trail above the canyon has also been opened to the public in 2018. During the 2018-2019 rainy season the Creek flowed vigorously with rainfall on another three occasions. Findings of the monitoring program (operated by the Maarag and the INPA) indicated that pH levels in the water holes have returned to normal levels (see below). Furthermore, the Acacia trees along the Creek were found to be uninfluenced, and improvement in chemical and biological parameters has continued. Nonetheless, indications of the incident’s impact are still present along the Creek, and the environmental influence continues to be examined by the Maarg. As part of this examination and per the requirement of the Ministry of Environmental Protection, ICL has initiated in 2019 a risk assessment process along the Creek. The assessment is meant to assure that the Creek’s hiking trails can be reopened and do not pose risks to the returning hikers health, pending approval of reopening by the necessary authorities. The risk assessment process is conducted by leading experts from Israel and abroad, utilizing advanced methodologies.

ICL remains strongly committed to supporting and assisting in the various operations being conducted along the dry river bed, including the long-term monitoring and restoration of the affected areas.
