Dear Mr. Goodrich:
A letter dated June 15, 1999 and signed by Dwight Lancaster stated that the North
Wilkesboro Wastewater Treatment Plant had been reclassified from a Grade IV Biological
Control Treatment System to a Grade III Biological Control Treatment System per the new laws
and regulations that have gone into effect.
This letter is to request a permit modification from monitoring 5-days per week to 3-days
per week. We feel that we now fall under the 3-day per week monitoring since the new laws and
regulations are now in effect.
If you have any questions, please feel free to contact me at the above address or by phone
