(Town of Parkt_Qn :.

In a letter dated September 18, 1991, the Town of Parkton requests that
the Town be allowed to begin Quarterly P/F toxicity monitoring as verses the
monthly monitoring only toxicity permit requirement. The Town has
consistently pasted four (4) months of toxicity tests and the Fayetteville
Regional Office has no objections to the Town's request.
Therefore, the Fayetteville Regional Office concurs with the Town of
Parkton's request to begin Quarterly P/F toxicity monitoring and recommends
that the appropriate permit modification be issued.

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.
Any consideration given this matter will be greatly appreciated.
Sincerely,
PC�� ""�Webb
