DNREC permit approval clears
way for cleaner air in Claymont
Significant upgrades under way at Evraz Steel plant
DOVER (Feb. 8, 2012) – DNREC Secretary Collin O’Mara has issued Evraz Claymont Steel a construction permit to install state-of-the-art pollution control equipment to collect dust and reduce other emissions at the plant – the new permit building on environmental progress in an earlier consent decree between DNREC and the company, which has committed to continue technology upgrades that improve air quality.
The consent decree signed in August 2010 by DNREC Secretary O’Mara and Evraz Inc. North America’s president and chief executive officer required Evraz Claymont Steel to implement a comprehensive series of investments in equipment and operational changes to make the plant and surrounding environment much cleaner. Many of those changes – including installation of state-of-the-art pollution controls to improve air-quality significantly in neighborhoods surrounding the Claymont steel mill – are well under way or nearing completion.
The new DNREC permit for Evraz requires additional dust control capacity at the plant and its “melt shop” by adding an additional new baghouse which will almost double the plant’s particulate collection and filter system by August 2013.
The emissions control technology authorized by the permit includes installation of systems to capture additional emissions from the electric arc furnace, stir station and ladle reheat operations and direct those emissions to the existing and expanded dust control baghouse. These upgrades are covered in detail in the permit issued by DNREC last month.
“These improvements will enhance the quality of life for residents of Claymont,” said Governor Jack Markell. “The changes represent a major commitment by Evraz to invest in Delaware and the company’s future here, and will position Evraz to continue as a significant contributor to our local economy in an environmentally sensitive manner.”
“We believe that these improvements will set this facility on a path toward long-term compliance, reducing local impacts and improving air quality for local residents,” said Secretary O’Mara. “We would not have made this progress without the persistence and engagement from the local residents who have been vigilant in collecting air and dust samples and continuing a constructive dialogue with Evraz leadership and DNREC.”
Other consent decree requirements for Evraz included the implementation of operational practices to reduce the potential for emissions and continued particulate monitoring around the facility. Evraz submitted its permit application and received this permit in accordance with the schedule outlined in the consent decree, and faced stipulated financial penalties if the terms and conditions of the order were not met.
The decree covered Evraz’s taking numerous actions to improve air quality. Bulleted below are stipulations that DNREC and Evraz agreed to in the consent decree, with the company’s progress to date at cleaning up the surrounding environment of the plant in boldface:
- Design, facilitate and install additional baghouse capacity and capture equipment no later than August 2013. A construction permit for these upgrades was issued to Evraz on January 20, 2012 and the facility is currently in the process of proceeding with the construction and improvements.
- Install state-of the-art control technology and to capture emissions from the electric arc furnace, stir station and ladle reheat operations and direct emissions to a baghouse. The construction permit which was issued to the Evraz allows for these upgrades.
- Move the slag cooling operations currently conducted outside to inside the melt shop within six months of the effective date of the order. Evraz began the slag cooling operation within the main melt shop structure in March 2011.
- Relocate the ladle slag dump area inside of the facility and install a water suppression system. By March 2011, the Evraz Claymont Steel facility had completed modifications to implement ladle slag cooling in the new location.
- Implement feed controls at the stir station until additional baghouse capacity and associated equipment are operational. Evraz is currently implementing a feed control monitoring procedure to limit the feed of materials to the stir station. This monitoring procedure will remain in effect until the new baghouse structure and conveyance system has been constructed.
- Modify the tapping hood to ensure proper alignment for tapping operation and for use during the ladle reheat process. New operating training procedures implemented by Evraz ensure the proper alignment of the tapping hood.
- Submit an updated Title V renewal permit application within 30 days of the order’s effective date. Evraz made its first submittal in September 2010, and additional submittals/addendums to the application are pending, following the newly issued construction permit.
- Maintain operations of four ambient air quality monitors and submit monitoring reports to DNREC. Evraz continues to maintain the ambient air monitors located in the nearby community and submits monitoring reports to the Division of Air Quality on a semi-annual basis for review.
- Evraz also continues to implement its enhanced mercury pollution prevention program, per the consent order, and DNREC’s Division of Air Quality continues to oversee the quarterly stack testing requirements for mercury emissions.
Evraz Claymont Steel, a wholly-owned subsidiary of Evraz Inc. North America, manufactures and sells custom-order steel plates and recycles scrap metal from the consumer and industrial refuse stream. Since acquiring the facility from Claymont Steel Holdings, Inc. in January 2008, Evraz has invested in improving the environmental performance of the facility including completing projects that were required of, but not completed by, the facility’s previous owner. These improvements include projects to enhance air pollution control practices, as well as voluntary measures to help control dust from the facility, including paving a large area of the site that was previously exposed.
