Dear Mayor Blevins:
Your modification request to delete the 85% TSS removal requirement from the subject
permit has been evaluated. As stated in a letter from the Division of Environmental Management
dated November 3, 1989, a lower percent removal requirement may be substituted only if a
facility meets the requirements of 40 CFR Part 133.103 (d) which are as follows:
1 . The treatment works is consistently meeting its effluent concentration limits but its
percent removal requirements cannot be met due to less concentrated influent
wastewater.
2. To meet the percent removal 'iequiiements, the treatment works would have to
achieve significantly more stringent limitations than would otherwise be required
by the concentration-based standards.
3. The less concentrated influent wastewater is not the result of excessive 1/I.
Our review has determined that the subject facility does not meet the first above mentioned
requirement. .Therefore, your request for an NPDES permit modification is hereby denied. The
Division will be glad to reevaluate your request for a reduction in removal efficiency after your
facility has been in compliance with the TSS limit for a period of at least twelve months.

Dear Mayor Blevins:
The Division of Environmental Management has reviewed your request dated October 3,
1989 for the relaxation of the 85% TSS removal requirement of the subject permit. However, a
lower percent removal requirement may be substituted only if a facility meets the requirements of
40 CFR Part 133.103 (d) which are as follows:
1. The treatment works is consistently meeting its effluent concentration limits but its
percent removal requirements cannot be met due to less concentrated influent
wastewater.
2. To meet the percent removal requirements, the treatment works would have to achieve
significantly more stringent limitations than would otherwise be required by the
concentration-based standards.
3. The less concentrated influent wastewater is not the result of excessive IA.
A review of the monitoring data submitted over the last twelve months indicates that there is
a consistent problem with meeting the TSS limit. Because the subject facility does not meet the
first abovementioned requirement, the TSS percent removal requirement will remain as 85% in the
subject permit.
After thirty (30) days from receipt of this letter, the Division will send your permit
modification request to public notice stating our intent to deny your permit modification request
unless you withdraw your request for a modification to the subject NPDES permit. If you wish to
withdraw your request for an NPDES permit modification, you may do so by stating that desire in
a letter to our office. Your letter must be received by our office within thirty (30) days of your
receipt of this letter.
