Title 42 › CHAPTER 85 — AIR POLLUTION PREVENTION AND CONTROL › SUBCHAPTER I — PROGRAMS AND ACTIVITIES › Part A — Air Quality and Emission Limitations › § 7429
The EPA must make rules that limit pollution from different kinds of solid waste incinerators and set other requirements for new and existing units. Deadlines: for units burning municipal waste over 250 tons per day, rules were due within 12 months after November 15, 1990; for units 250 tons per day or less and for hospital/medical/infectious waste, within 24 months; for commercial or industrial waste, a proposal within 36 months and final rules within 48 months; and a schedule for other categories within 18 months. Rules must aim for the greatest pollution cuts EPA finds achievable while considering cost, health and environmental effects, and energy needs. New units must meet at least the level of control achieved by the best similar unit. Existing units may have less strict limits but not weaker than the average limit achieved by the best-performing 12% of units (with a specific exclusion for units that recently met the lowest achievable rates). EPA must review and update standards every 5 years. The rules must be based on pollution controls used before, during, or after burning and must include site rules to reduce health risks. EPA must set numeric limits for particulate matter (total and fine), opacity, sulfur dioxide, hydrogen chloride, oxides of nitrogen, carbon monoxide, lead, cadmium, mercury, and dioxins and dibenzofurans. Owners must monitor emissions at the stack (and other places if needed), track other operating data, report results, keep records at the facility, make them available to the public, and report any exceedances separately. EPA had to create a model training and certification program within 24 months after November 15, 1990, and 36 months after standards for a category are set it is illegal to operate a unit unless the people controlling emissions are properly trained. States must send EPA a plan within 1 year after EPA issues guidelines; units must comply within 3 years after the State plan is approved but no later than 5 years after the guidelines. If a State fails, EPA will make and enforce a federal plan within 2 years. New-unit rules take effect 6 months after they are issued; existing-unit rules take effect as soon as practicable after plan approval but no later than 3 years after plan approval or 5 years after issuance, whichever is earlier. After rules start, it is illegal to operate in violation. Each unit must have a permit beginning 36 months after the rule or when a State permit program starts, whichever is later; permits can last up to 12 years and must be reviewed every 5 years. States may set stricter rules. Definitions (one line each): solid waste incineration unit = a unit that burns waste from homes, businesses, or the public; new unit = built after EPA proposes standards; modified unit = major change that raises emissions or costs over 50% of original; existing unit = not new or modified; municipal waste = household and similar refuse (with stated exclusions).
