The government has removed roadblocks to coal mining by leading business houses and taken the first step to relax scrutiny of corporate expenditure on oil and gas fields, in a burst of action that has cheered investors and industrialists in the languishing energy sector. A group of ministers recommended to the cabinet on Wednesday that Reliance Power's Chhatrasal block, which is attached to the 4,000 mw Sasan Ultra Mega Power Project, and Mahan block for captive use by Hindalco and Essar should be given forest clearance, subject to some conditions.
