Dear Ms. Jackson:
I have received our N.P.D.E.S. Permit, and I have one item of the permit I would like
to change. I would like to request a change in the weekly average Fecal Coliform limit.
Because M.S.L.D. is a small system with no in-house laboratory, samples have to be
taken to a lab in Greenville. We appreciate the fact that our measurement frequencies are
for the most part weekly. However, Fecal Coliform is based on geometric mean; and, if
we have a weekly limit, samples have to be taken at least twice a week There are so
many ways for a Grab Sample to become contaminated, and I do not usually hear from
the lab until the week after I have taken my weekly sample. If I didn't have to worry
about chlorine residual like some of the towns around us, then we could shoot the
chlorine to the contact basin and never worry about Fecal Coliform. However, we have a
28 microgram limit.
Based on the above information, I am requesting that the weekly limit on Fecal
Coliform be lifted. If the limit is lifted, I won't have to concentrate so much time and
money on one characteristic.
