On October 29, 2009, the EPA promulgated national emission standards for the control of hazardous air pollutants for nine area source categories in the chemical manufacturing sector: Agricultural Chemicals and Pesticides Manufacturing, Cyclic Crude and Intermediate Production, Industrial Inorganic Chemical Manufacturing, Industrial Organic Chemical Manufacturing, Inorganic Pigments Manufacturing, Miscellaneous Organic Chemical Manufacturing, Plastic Materials and Resins Manufacturing, Pharmaceutical Production and Synthetic Rubber Manufacturing. Following that action, the Administrator received a petition for reconsideration. In response to the petition, the EPA is reconsidering and requesting comment on several provisions of the final rule. The EPA is also proposing certain revisions t...

The Mining industry covers establishments primarily engaged in the extraction of minerals, coals, and ores from the earth. The mining industry provides ores and raw metals to mills and metal fabricators. Over the past few years, commodity prices have been trending upwards. The global boom in commodities includes a number of metals. Historically, the domestic coal industry has been susceptible to economic changes. The current weakening of the US economy is likely to decrease demand. Like the metals sector, the coal industry is seeing increased demand from international markets. While international markets clearly provide an opportunity for expansion, coal producers need to proceed carefully. Domestic demand for metals is likely to fall, as the economy weakens and production continues to ...

The EPA is proposing amendments to the national emissions standards for hazardous air pollutants for Ferroalloys Production to address the results of the residual risk and technology review that the EPA is required to conduct under the Clean Air Act. These proposed amendments include revisions to particulate matter standards for electric arc furnaces, metal oxygen refining processes, and crushing and screening operations. The amendments also add emission limits for hydrochloric acid, mercury, polycyclic aromatic hydrocarbons, and formaldehyde from electric arc furnaces. Furthermore, the amendments expand and revise the requirements to control fugitive emissions from furnace operations and casting. Other proposed requirements related to testing, monitoring, notification, recordkeeping, a...
