ASTRAZENECA HAS REPORTED FUEL USE FOR ITS DUAL -FUEL BOILER (FUEL OIL AND GAS) ON A YEARLY BASIS, RATHER THAN BI-ANNUALLY AS REQUIRED. THE FACILITY HAD REQUESTED AND RECEIVED APPROVAL TO REPORT ON A YEARLY BASIS, BUT ONLY WHEN NO FUEL OIL WAS BURNED. IN 2003 THE FACILITY BURNED FUEL OILIN BOTH SIX-MONTH PERIODS, THEREFORE SHOULD HAVE REPORTED BI-ANNUALLY.
