General wastestream

For each waste treatment method, indicate the type of waste-stream containing the chemical that is treated. Enter the letter code that corresponds to the general wastestream type ... 

In Part III, you are to identify the toxic chemical being reported. You must indicate the general uses and activities involving the chemical at your facility. In Part III, you will also enter quantitative data relating to releases of the chemical from the facility to air, water, and land. Quantities of the chemical transferred to off-site locations, identified in Part II, are also reported in this part. Any waste treatment information for onsite treatment of wastestreams containing the toxic chemical are also required to be reported on Part III. An optional section is included in this part that allows you to report waste minimization information associated with the chemical. 

Economical factors, such as disposal costs, the availability of conventional materials, and transportation costs, are critical considerations. As with any material, transportation costs are generally the highest cost factor in recycling solid waste. The most economically sustainable options for recycling foundry solid waste will generally match the volume and characteristics of the materials with nearby businesses and construction projects. Small foundries may not generate enough material on a weekly or monthly basis to satisfy the need for construction sands. In this case, it may be necessary to collect similar wastestreams from multiple sources or to partially substitute for conventional materials in order to meet volume requirements. 

After issuance, permits may need to be modified to allow facilities to implement technological improvements, comply with new environmental standards, respond to changing wastestreams, and generally improve waste management practices. These modifications can be initiated by either the facility or the permitting agency.
