[Company Profile]
Clean Harbors, Inc. was incorporated in Massachusetts in 1980 and the company's principal office is located in Norwell, Massachusetts. Clean Harbors, Inc. and its subsidiaries is a leading provider of environmental, energy and industrial services throughout North America. the company serves over 60,000 customers, including a majority of Fortune 500 companies, thousands of smaller private entities and numerous federal, state, provincial and local governmental agencies. The company's operations may be affected by seasonal fluctuations due to weather and budgetary cycles influencing the timing of customers' spending for remedial activities. Typically during the first quarter of each year there is less demand for environmental services due to the cold weather, particularly in the Northern and Midwestern United States and Canada. Accordingly, reduced volumes of waste are received at its facilities and higher operating costs are associated with operating in sub-freezing weather and high levels of snowfall.
