There are only minor environmental risks facing the company. These risks are identified and listed, and the company strives for continuous improvement in its environmental performance by seeking ways to reduce the risks associated with these items.
Ridley Terminals Inc. successfully completed a compliance audit of its Environmental Management System, ISO 14001, in June 2011.
ENVIRONMENTALLY SOUND TERMINAL OPERATING PRACTICES
Terminal design and materials handling procedures ensure both high performance and a clean operation. To protect the rich coastal environment, RTI has made every effort to keep coal where it belongs – either on the terminal site, or in the ships which carry it to customers.
Railcars are loaded at the points of origin with flat profiles along the top of the load. The surface is sprayed with an anti-erosion material to prevent dusting while in transit.
During the unloading of each railcar, a water spray bar shoots out a mist to keep the coal fines in the dumping area. Railcars are washed immediately after unloading for the return trip to their points of origin.
To prevent wind erosion in the stockyard, storage piles are dampened with water from 26 automatic sprayheads. All weather parameters that affect the propensity of dust particles to become airborne are continually monitored. These parameters are then factored into a formula which results in what is known as a K-factor. When the K-factor approaches or exceeds the limit where dust conditions will occur, an alarm is announced over site radios, and the automatic sprayheads are turned on.
The sprayhead system is backed up by a 3,000 gallon water truck and crew to spray down any hard to reach spots in the stockyard, and to keep all site roads well soaked.
A closed-loop system of drainage ditches around the terminal directs runoff to a settling pond where any coal fines are recovered. The water is recycled.
