Associate Administrator for Rulemaking

Dear Mr. Felrice: 

As part of EPA's agreement with the Department of 

Transportation to consult on safety issues related to the 

onboard vapor recovery rulemaking, I have enclosed copies of 

comments received during the public comment period. I have 

included a copy of all of the substantive comments received but 

have excluded repetitive "form letter" type comments, letters 

from private citizens, letters from Congressmen, and comments 

from small trade associations. These omitted comments are 

numerous and do not appear to contain substantial new 

information. For your use, I have enclosed a list of all 

documents in the public comment section of the docket for the 

onboard rulemaking (Docket A-87-11). If there are additional 

comments which you would like to obtain copies of, please 

contact Phil Carlson of my staff at FTS 374-8270 for assistance. 

Please be aware that I have also included confidential 

comments, which were received from Chrysler, Ford and 

Daimler-Benz. Due to the proprietary and confidential nature 

of the information, the manufacturers have requested this 

information be given confidential treatment. The information 

is on pages clearly marked "CONFIDENTIAL" and is entitled to 

confidential treatment pursuant to Section 208(b) of the Clean 

Air Act, as amended, 42 USC 7542(b) (1977), Sections 552(b)(4) 

and 552b(c)(4) of the United States Code (Exemption 4 of the 

Freedom of Information Act), and Part 2, Subpart B of Title 40 

of the Code of Federal Regulations. 

It is my understanding that NHTSA has received a complete 

copy of the GM docket submittal (A-87-11-IV-D-360), including 

two videocassettes. Therefore, I have included only the major 

comment volumes and have omitted the light-, medium- and 

heavy-duty data books as well as the two videocassettes and the 

five large blueprint test procedure sheets which GM submitted.
