EPA proposed to amend the Title 40 of the Code of Federal Regulations (40 CFR) Part 264, Subpart 0, general (permit) standards published in the Federal Register (FR). The proposed amendments apply primarily to the incinerator performance standards (40 CFR section 264.343) and include emission limits for hazardous combustion by-products, a variance standard based on an assessment of risk to human health, and a procedure to set emission limits for toxic metals and hydrogen halides based on an assessment of risk. In addition, the procedure for designation of principal organic hazardous constituents (40 CFR section 264.342) was proposed to be amended to include hazardous combustion by-products.
