  **Seasonality**
  
  Our operations can be adversely aÅected by periods of inclement weather which could increase the 
  volume of waste collected under our existing contracts (without corresponding compensation), delay the 
  collection and disposal of waste, reduce the volume of waste delivered to our disposal sites, or delay the 
  construction or expansion of our landÑll sites and other facilities. 
  
  **New Accounting Pronouncements**
  
  On December 16, 2004, the Financial Accounting Standards Board issued Statement of Financial 
  Accounting Standards No. 123 (revised 2004), ""Share-Based Payment,'' which is a revision of SFAS 123, 
  ""Accounting for Stock-Based Compensation.'' SFAS 123(R) supersedes APB Opinion No. 25, ""Accounting 
  for Stock Issued to Employees,'' and amends SFAS 95, ""Statement of Cash Flows.'' Generally, the approach 
  in SFAS 123(R) is similar to the approach described in SFAS 123. However, SFAS 123(R) requires all 
  share-based payments to employees, including grants of employee stock options, to be recognized in the 
  income statement based on their fair values. Pro forma disclosure is no longer an alternative.
