        Dear Sir or Madam:
      
             We invite you to join us on January 14 and 15, 1998,
        in Sacramento, California for two consumer product
        meetings.  We will discuss the consumer products draft
        survey, and reactivity options for consumer products. 
        These meetings are follow-up sessions to the November 18-
        19 Consumer Products Working Group (CPWG) meeting.
        
             At the CPWG meeting, we explained that a consumer
        products survey is needed to update the State
        Implementation Plan (SIP) inventory and modeling, develop
        reactivity-based standards, and prioritize categories for
        standard development.  In response to industry comments,
        we agreed to look at ways to streamline the survey
        process where feasible.  Regarding reactivity options,
        while there is general support conceptually, there are
        concerns about implementation.  So we would like to
        devote time towards explaining the science, background
        and options.
         
             We invite your participation in these meetings.  The
        time, date and location are as follows:
        
               Date:          January 14-15, 1998
               Time:          8:30 - 3:30 p.m. (Jan. 14)
                              8:30 - noon (Jan. 15)
               Location :     California Air Resources Board
                              2020  L  Street
                              Board Hearing Room
                              Sacramento, California
        
             On the first day, we plan to:  (1) provide a brief
        summary of the inventory status and discuss the
        objectives of the meeting; (2) discuss the quality of
        data for the various categories of consumer products, and
        identify areas needing more information; and (3) discuss
        strategies for filling the data gaps, including the
        content of the survey, and the categories to be surveyed. 
        Optional methods for obtaining necessary data will also
        be discussed.  We will provide documentation of the
        latest emissions estimates by category to interested
        parties in early January.  Enclosure 1 is a proposed
        agenda for the consumer products survey and inventory
        discussion.
        
             On the second day, we plan to:  (1) provide an
        introduction and overview of the concept of relative
        reactivity of volatile organic compounds and technical
        research; (2) discuss the issues relevant to the
        regulatory development of reactivity-based standards; 
        and (3) provide examples of how the program could work.  
        Enclosure 2 is a proposed agenda for this meeting.
        
             We hope you will be able to participate in these
        meetings.  There is no need to notify us regarding your
        plans to attend.  However, persons with disabilities who
