Description
Excerpt: EPA?s Phase 1 certification database and the regulatory programs for handheld engine manufacturers being adopted for Phase 2. The number of handheld engine families that are expected to be improved are estimated based on the use of ABT by the engine manufacturers4 and the comparison of their deteriorated5 Phase 1 emission rates to the Phase 2 standard with a 10 percent compliance margin6. Technology improvements for handheld engines include mini four-stroke, stratified scavenging with lean combustion and a catalyst, and compression wave with and without a catalyst. The estimated costs for each technology are also presented in this chapter. Costs for Class I-A standards are minimal as Class I-A allows handheld engines to be used in nonhandheld applications. Therefore the technology costs are attributed to the handheld rulemaking. Class I-B costs are minimal for the standard allows existing engines to meet the standards without modification. The only costs are those that are attributed to certification and other related applicable costs which are the same as those for other engine families.
