toxicity monitoring requirements with the pass/fail limitation. The Town has
passed four (4) consecutive months of toxicity tests, which appears to

SUBJECT: Aquatic Toxicity Tests-
.
Dear Mr. Overcash:-
The Town of Parkton has for the past -six (6) months conducted monthly aquatic
toxicity tests (copy attached) at our.wastewater treatment plant to try_and
establish a limit for a quarterly report.-
Parkton is a small rural town with' a population of approximately 385 and
approximately 200 houses on our sewer system. Since these tests are so ex-
pensive and we operate on such a limited budget, we-would!like to request that
you consider setting a limit for Parkton in order that',we'can begin reporting
this test on a quarterly basis right away.
Attached is a check in the, amount of $50.00 to cover this request per my phone
conversation with Kitty Kramer,in.Fayetteville today. r .
Any consideration given this -matter will be greatly appreciated.
.. I
Sincerely,
q
