IN LOMBARD, ILL. WHICH IS A SUBSIDIARY OF GNB, INC. OF ST. PAUL, MN. GNB HAS INSTALLED NEW EQUIPMENET SINCE JANUARY 14, 1980 WHICH IS THE APPLICABILITY DATE FOR THE STANDARDS OF PERFORMANCE FOR LEAD-ACID BATTERY MANUFACTURING PLANTS, 40 C.F.R. 60, SUBPART KK. THE FACILITY IS SUBJECT TO NSPS SUBPARTS A AND KK. THE NSPS REGULATIONS REQUIRED GNB TO NOTIFY EPA OF A PHYSICAL OR OPERATIONAL CHANGE TO AN EXISTING FACILITY WHICH MAY INCREASE THE EMISSION RATE OF ANY AIR POLLUTANT TO WHICH A STANDARD APPLIES. SUCH NOTIFICATION WAS REQUIRED TO BE POSTMARKED 60 DAYS OR AS SOON AS PRACTICABLE BEFORE THE CHANGE IS COMMENCED. THE NSPS REGULATIONS ALSO REQUIRED GNB TO CONDUCT PERFORMANCE TESTS ON AFFECTED FACILITIES CONSTRUCTED AFTER JANUARY 14, 1980.
