Gurugram, April 16 -- The Haryana State Pollution Control Board (HSPCB) on Wednesday issued notice to 140 red-category large and medium-scale industries in the district asking them to comply with new emission standards set by the Central Pollution Control Board (CPCB) in February. The standards aims at reducing the maximum permissible particulate matter (PM) discharge limit from 80mg/Nm³ (milligrams per Normal Cubic Meter) to 50mg/Nm³. According to officials the industries are now required to install upgraded anti-pollution control devices (APCDs), which will demonstrate a live emission model on the CPCB's new portal starting from August 1. According to the HSPCB officials, the new rules apply to "highly-polluting" industries across 17 categories. "Based on studies conducted by the Indian Institute of Technology (IIT), Kanpur, industries with boilers and metal furnaces have been directed to rely on fabric bag filters to effectively trap pollutants," said Siddharth Bharghava, regional officer of HSPCB, Gurugram (South). To be sure, red-category industries are high in spreading emissions, including textiles, distilleries, food processing, cement factories, among others. Earlier in January, the HSPCB issued notices to 28 industrial units in Gurugram for failing to comply with the new online continuous emission monitoring system (OCEMS), an online system to track emissions of industries. "Following which, a majority of them applied for the OCEMS," an HSPCB official said. Officials said inspections have been conducted over the past few weeks to ensure that the industries use clean fuel such as the piped natural gas (PNG) and biomass fuel with installed APCDs. "While medium and large industries are required to comply with new APCD norms by July 31, the remaining categories will have to adopt emission control measures by September end," the senior official added....
