Area sources of HAPs are those source that fall below the Major source threshold. Institution of a new definition of solid waste which will render certain boilers "Commercial and Industrial Solid Waste Incinerators" (CISWI). establishment of stricter emissions limitation for HAPs on CISWIs in addition to new monitoring, testing, inspection and reporting requirements. Highlights of the proposed rule include: Boilers and process heaters considered CISWIs are subject to different requirements than other boilers and process heaters under the rule. Small boilers and process heaters (those under 10mm BTU/hr capacity) and boilers and process heaters that use natural gas (or refinery gas) will be subject to work practice standards including periodic "tune-up" requirements instead of emissions limitations. In addition to new emissions limits, existing...
