Section 3 13's purpose is to malce information available on the amount of specific toxic 

 chemicals released to the environment from manufacturing facilities EPA is required to 

 make this information accessible on a computerized database The Toxic Release 

 Inventory (TRI) database became available in June 1989 through the National Library of 

 Medicine's TOXNET system. EPA also is providing information on microfiche, computer 

 tape, CD-ROM and diskette for analysis by interested organizations and individuals 

 Annual reports have been prepared by EPA to summarize release data by industry, region 

 and chemical. 



Ketchikan Pulp Company is required to develop reasonable estimates of amounts of 

 chemicals released. KPC has historically relied on pulp mill specific data If it has not 

 been available, Ketchikan Pulp Company has referred to industry data, specifically the 

 National Council For Air and Stream Improvement for the Pulp and Paper Industry's 

 (NCASI) SARA Release Reporting documents The report allows for estimates based on 

 monitoring data or measurements, estimates based on mass balance calculations, estimates 

 based on published emission factors, or estimates based on engineering calculations or best 

 engineering judgment.

 "otherwise using" section 313 chemicals Manufacturing and processing thresholds are set 

 at 25,000 pounds per year The "otherwise use" threshold is 10,000 pounds per year 

 Any chemical that meets any of the three reporting thresholds must be reported for all
