HYDERABAD: The Hyderabad SITE Association of Trade and Industry has condemned the Sindh Environment Protection Agency (SEPA) for sealing 15 factories, terming the action as illegal. Addressing a news conference here on Saturday, the office-bearers of the SITE association including Salahuddin, Nadeem Siddiqui, Shahid Qaimkhani and Chowdhry Mazhar, along with Hyderabad Chamber of Commerce and Industry Vice President Ziauddin termed the sealing of 15 factories as an attempt to halt the wheel of industry and render hundreds of thousands of workers jobless. They said that drainage, garbage and other wastage of municipal committees and Wasa were responsible for 97% of pollution in the city. They warned SEPA to stop harassing industrialists. They said that the government had built treatment plants at Hyderabad and Kotri with a cost of billions of rupees but both had been non-functional due to inefficiency of departments concerned.
