Reckless blasting on NH-707 raises environmental, safety concerns

The construction of National Highway 707 (NH-707) from Paonta Sahib in Sirmaur to Gumma-Fedizpul in Shimla has sparked serious concerns due to the unchecked use of explosives by construction firms. Allegations of reckless and unscientific blasting have raised fears of environmental degradation, loss of water sources and potential disasters.

Local residents and environment experts have warned that frequent high-intensity explosions have disrupted groundwater flow, leading to the drying up of natural springs and streams that once provided drinking water to nearby villages. The unregulated dumping of debris has further worsened the region’s water crisis, impacting both human settlements and agriculture.

Additionally, continuous blasting has caused cracks in mountains, significantly increasing the risk of landslides and rockfalls. Experts caution that such unscientific construction practices could lead to large-scale geological instability, endangering lives and infrastructure. Dust and debris from the explosions have adversely affected flora and fauna, posing long-term ecological risks.

Despite strict restrictions on the use of high-intensity explosives, private firms have allegedly been conducting unregulated dynamite blasts, often without proper authorisation. Residents report hearing loud explosions from several kms away, raising serious concerns about public safety.

Environmental activist Nathu Ram Chauhan has criticised the administration for its failure to regulate the blasting activities. "The Deputy Commissioner of Sirmaur permitted private firms through MoRTH to carry out blasting operations in the Hewna-Ashyari section (Km 25 to 50) without considering the long-term consequences. How can such permissions be granted?" he questioned. Chauhan further alleged that construction firms, despite being given permits for controlled blasting, have been carrying out large-scale detonations, weakening the mountains and increasing disaster risks.

Despite violations, the Ministry of Road Transport and Highways (MoRTH), responsible for monitoring highway construction, has been accused of turning a blind eye on the issue.

When asked, MoRTH Project Director Saswat Mohapatra defended the construction activities, stating that "controlled blasting was carried out only once, with all safety regulations and administrative guidelines strictly followed."

Sirmaur Deputy Commissioner Sumit Khimta assured that "blasting was approved under strict conditions and any negligence will be dealt with as per regulations."
