The indU9- try..,upported regu1.aticm was originally proposed. in De- c"rober 1991. but has taken nearly two year!! to finaliZl!. The most significant ali-peet of th<! new rule i:i that only ~ frige:ralect condensers can be used rot add-on control. They must haVg It dual coil to anow for the capture of va-- por!! from the wuher and dryer. Somg older. singlg c:oil re- frigerated condgMC!1'9 may have to bQ retrofitted. AU other add-on control devices lI~ch as calbon vapor adsorbers and other controls are not approved, although carbon vapor ad80rbers have been grandfathered in most cases. Also. insUiUation of a new or roplacement twTJblgr or re- dehner, 101m not be allowed. In oiher words. if your tum- bler or reclaimsr needs replacement, you wiD have to purdlase II dry-to-dry systmn as described below. A Sum- mary of this and other new requlremenl9 fur dryc1eaners is below. IfT will be providing further deta.i1s of the full perc standard In an upcomillg Fabrir,a~ Ntws. SUMMARY: FINAL EPA PERC AIR STANDARD Existing Transfer Equipment Using less tlwn 200 gallons 0/ peTe per year per plant: . Exempt from aU requirements except for Initial re- porting to EP A and for some basil: record keeping and maIntenance items. Using more thall 200 gallons per year. bur less Ihan 1.800 gallons ptr year per plant: . If not almady uaing a carbon adsorber or an add-on re- frigerated condenser-wtall II refrigerawd condenser. . If already ming a camon adsorber-no new Ilquip- ment needed. . If already using a refrigera~d conden!W!r--no new equipment required. . If rgpladng the cl98ning machine itself-iNtall B vented dry-to-dry machine with add-on n!frigt!ration, or install a dry-to-dry closed loop refrigerated ma" cltlne. Ifusing more than 1,800 gallons per year per plant: . M\I,t install II room enclo9\11'e with <:arbon adsorber. . If not already u9in.g II carbon adsorber or an add-on ro- frigerated condenser-install a reITigerated condenser as wel1 a9 a carbon adsorber to be used with the room enclosure. . U already using I carbon I\ds~o new equipment requited. Although lI'Iust ,till use a room endOilJl'e. · If al",ady using a refrigerated condenser-will also need to purchase a carbon adsorber to be u!led with the room enclosunI. New Transfer Plants No new transfer equlpmQnt wiU bg permitted. under thQ standard. ExJltlng Dry~o-Dry Vented Equipment Using less tluVl 140 gallons of pere per year per plQJIc: . Exempt &om aU roquirements except lor initial report. Ing to EP A and for some basi<: record keeping and maintenance itr!nu. . Using more than 140 gallolLS 0/ pere per year per plan!: ., It not already using a carbon adsomer or an add-on rC!- frigeramd condenser-install a refrl~rated condenser. . U already lDing a carbon adsotber-no new equiplI\2Jlt reql.dred. . If already using a refrigeral:l!d condenser-no new equipment ~uin:d. New Dry-To-Dry Vented EquJpment Using less than 2,100 gallons per year: . In,tall a vented dry-to-dry mac:hine with add-on roErig- eration or install a closed loop refrigerated ma.chine. Using more ,han 2.100 gallons per year: . Install a dry-to-dry dosed loop rehigerated machin9 with carbon adsorption. (Carbon adsorption in this Cas9 ",(ers to a small carbon unlt used to caphue any remaining vapors left in the wheel upon completion of the drying pro<<!ss.) Existing Dry-to-Dry Refrigerated NNo--Vent" Equipment . Will meet aU requirements of the standard. New Dry-to-Dry Refrigerated Equipment Using more than 2.100 gallons per year: .
