INTRODUCTORY STATEMENT 

INTRODUCTION AND WELCOME 

GOOD MORNING. ON BEHALF OF THE ENVIRONMENTAL PROTECTION 

AGENCY, I WOULD LIKE TO WELCOME ALL OF YOU TO TODAY'S HEARING. MY 

NAME IS DICK WILSON. I AM DIRECTOR OF THE OFFICE OF MOBILE SOURCES. 

I WILL BE SERVING AS THE PRESIDING OFFICER FOR TODAY'S HEARING. 

THE EPA PANEL WILL CONSIST OF MYSELF, CHARLES GRAY, DIRECTOR 

FOR REGULATORY PROGRAMS AND TECHNOLOGY, CHET FRANCE, DIRECTOR 

OF THE REGULATION DEVELOPMENT AND SUPPORT DIVISION, GLENN 

PASSAVANT, CHIEF OFTHE SPECIAL REGULATORY PROJECTS BRANCH, STEVE 

SILVERMAN FROM THE OFFICE OF GENERAL COUNSEL, CHUCK FREED FROM 

THE MANUFACTURERS OPERATIONS DIVISION, AND CHARLES HOTT FROM THE 

NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION. 

WE WILL BE HEARING TESTIMONY TODAY ON A NOTICE OF PROPOSED 

RULEMAKING FOR PROVISIONS CONCERNING ONBOARD REFUELING CONTROLS 

FOR LIGHT-DUTY VEHICLES, LIGHT-DUTY TRUCKS AND HEAVY-DUTY VEHICLES 

PURSUANT TO THE PROVISIONS OF THE CLEAN AIR ACT AS AMENDED IN 

NOVEMBER OF 1990. EPA'S LATEST NOTICE ON THE PROPOSED REGULATIONS 

WAS PUBLISHED IN THE FEDERAL REGISTER ON MAY 27, 1993. 
P.4 

IN THAT NOTICE, EPA IDENTIFIED TEST PROCEDURE OPTIONS THAT 

WOULD COMBINE THE REFUELING AND NEW EVAPORATIVE TESTS TO THE 

GREATEST DEGREE POSSIBLE. THE GOALS WERE TO REDUCE THE TESTING 

BURDEN AND TO ALLOW, IF NOT ENCOURAGE, THE USE OF INTEGRATED 

EVAP/REFUELING CANISTER SYSTEM DESIGNS. IN DEVELOPING THE OPTIONS, 

EPA EXPECTED THAT THE REQUIREMENTS FOR REFUELING EMISSIONS 

CONTROL WOULD RESULT IN SIMILAR INTEGRATED SYSTEMS CANISTER SIZES 

AND PURGE DESIGNS AS THOSE REQUIRED FOR EVAPORATIVE EMISSION 

CONTROL SYSTEMS. 

SINCE PUBLICATION OF THE NOTICE, EPA HAS HAD SEVERAL TECHNICAL 

MEETINGS WITH REPRESENTATIVES OF THE AMERICAN AUTOMOBILE 

MANUFACTURERS ASSOCIATION (AAMA) CONCERNING THE TEST PROCEDURE 

REQUIREMENTS NECESSARY TO ACCOMPLISH EPA'S STATED GOALS FOR 

INTEGRATING THE REFUELING AND EVAP TEST PROCEDURES. IN PARTICULAR, 

THE FUEL TEMPERATURE SPECIFICATIONS OF THE REFUELING TEST WERE 

DISCUSSED IN DETAIL. AS A RESULT OF THESE MEETINGS REVISIONS TO THE 

REFUELING TEMPERATURE REQUIREMENTS WERE IDENTIFIED. SPECIFICALLY, 

A DISPENSED FUEL TEMPERATURE OF 67°F AND TANK TEMPERATURE OF 80°F 

IS NOW THOUGHT TO RESULT IN A REFUELING CANISTER SIZE SIMILAR TO THAT 

REQUIRED BY THE EVAP TEST PROCEDURE. EPA BELIEVES THAT THESE 

REVISIONS WOULD PROVIDE GREATER FLEXIBILITY TO MANUFACTURERS IN 

DESIGNING THEIR REFUELING CONTROL SYSTEMS AND SHOULD RESOLVE 
P.5 

SAFETY CONCERNS PREVIOUSLY EXPRESSED IN THE RULEMAKING RECORD. 

EPA IS THEREFORE, CONSIDERING ADOPTION OF REFUELING OPTION B1 

AS DESCRIBED IN THE NOTICE ALONG WITH THE CHANGES IN THE 

TEMPERATURES AS DESCRIBED ABOVE. ADDITIONAL INFORMATION REGARDING 

THE MEETINGS WITH AAMA IS IN THE DOCKET FOR THIS RULEMAKING. EPA 

REQUESTS COMMENTS ON THIS NEW OPTION AS WELL AS THOSE DESCRIBED 

IN THE NOTICE. 

BEFORE GETTING STARTED WITH TODAY'S TESTIMONY, I WOULD LIKE TO 

TAKE A FEW MINUTES TO DESCRIBE HOW WE WILL CONDUCT THE HEARING.

307(d)(5) OFTHE AMENDED CLEAN AIR ACT, WHICH REQUIRES EPA TO PROVIDE 

INTERESTED PERSONS WITH AN OPPORTUNITY FOR ORAL PRESENTATION OF

WRITTEN SUBMISSIONS. 

THE RECORD OF THIS HEARING WILL REMAIN OPEN UNTIL AUGUST 22, 

1993 FOR ADDITIONAL WRITTEN COMMENTS OR REBUTTAL. 

THE HEARING WILL BE CONDUCTED INFORMALLY, AND FORMAL RULES OF 

EVIDENCE WILL NOT APPLY. THE PRESIDING OFFICER IS AUTHORIZED,
