A study was made of the timber products processing point source category, for the purpose of developing information to assist the EPA in establishing effluent limitations guidelines and standards to implement sections 301, 304, 306, and 307 of the Federal Water Pollution Control Act Amendments of 1972. The document is the result of that study.

A study was made of the time products processing point source category for the purpose of developing information to assist the Agency in establishing effluent limitations guidelines and standards to implement Sections 301, 304, 306, and 307 of the Federal Water Pollution Control act Amendments of 1972. The portions of the industry studied included the insulation board manufacturing, particleboard manufacturing, sawmills and planing mills, wet storage, i.e., pond and wet deck storage of unprocessed wood, and the operations of log washing, finishing, fabrication, by-product utilization and dry deck storage. The wet storage, sawmills, particleboard and insulation board segment of the timber products processing industry is divided into seven subcategories. The subcategorization was based on the processing procedures involved and the water requirements, in terms of both quantity and quality. The subcategories presented in this document are: wet storage, log washing, sawmills and planing mills, finishing, particleboard manufacturing, insulation board manufacturing and insulation board manufacturing with steaming or hardboard production. Best Practicable Control Technology Currently Available (BPCT), Best Available Technology Economically Achievable (BAT), and New Source Performance Standards (NSPS) for five subcategories in this segment of the industry is defined as no discharge of process waste waters pollutants to navigable waters. The insulation board manufacturing portion of the segment has quantitative limits on discharge. Limits on the wet storage subcategory are basically no discharge of waste water pollutants with an allowance for discharge volume related to precipitation-evaporation considerations.
