January 15, 2012. The Hul hydropower project will ruin five km or one-fourth of the catchment of the Hul stream, a tributary of the Saal river, environmentalists say. It will also affect the livelihood of over 6,000 locals. Seven mini and micro hydro projects have been proposed on the Saal river alone. Since 2003, the people of eight panchayats in the Saal Valley of Chamba, under the banner of the Saal Ghaati Bachao Sangharsh Morcha, have been demonstrating against the Hul Hydro Power Private Ltd (HHPPL), the company executing the 4.5 MW project. According to Himachal Pradesh's micro-hydel policy, the consent of the affected gram sabhas (local bodies) is necessary before constructing any project.
