Please note that in Part III, special condition #13 (e) allows for a reduction in the monitoring from monthly to quarterly after twelve consecutive months of toxicity testing has been_ completed.
Additionally, it is requested that Part III, special condition #14 be put into effect.
This will allow pages 5 & 9 of the permit to become effective and for pages 4 & 8 to expire.
Pages 5 &
9 require that 1
sample per month be collected.
Therefore, if the request to drop the frequency to quarterly is
- granted, these sheets will need to be revised by the State to show the new frequency of quarterly sampling. Additionally, pages 5 & 9 differ from pages 4 & 8 in that Part III, Special Condition #13 e is omitted from the requirements.
This is the condition which requires that a toxicity evaluation plan be submitted following a failed toxicity test.
We would like for the State to verify that this is correct.
If possible we would like a response to this request prior to the November, 1993 sampling.
If you need additional information or have any questions please call John Estridge at (704) 875-5965 or Robert Wylie at (704)875-5970.
Sincerely, John Carter, Technical System Manager Environmental Division, Water Protection Jte/240 cc:
