Dear Mayor Matthews:
Please -accept my apology for the delay in responding to your questions regarding
the proposal to connect your existing wastewater treatment plant to the facility owned and
NCO061492). 1 .'The Division
operated by. Maury Sanitary District (NPDES'Permit No.
believes that the consolidation of these two plants will be beneficial to the environment
and is ready to assist you in this endeavor to the extent possible.

In all likelihood, the distribution of the aggregate allocation for these smaller facilities
would be similar to the allocations given to the larger facilities in the Neuse River basin.
That is, each discharge may be required to meet the same concentration limits for total
nitrogen based on permitted flow. (It should be noted, however, that it is unlikely that
concentration limits as low as those given to the larger discharges would be required of
the smaller facilities.)
As a result of the uncertainty regarding the potential for limits in future permits, I realize
that this is a complicated situation and would be happy to meet with you and
representatives of the Maury Sanitary District if you would like. Given the tight time
frames associated with your potential ftmding, I will make every effort to schedule such a
meeting as soon as you request one. Since I will not be in the office the week of
September 14', you may direct your inquiries to Mr. Mike Templeton at (919)-733-5083,
extension 541. 1 will return on September 21, 1998 and can be reached at the same phone
number, extension 517.
