Yeah, Mike, a simple "correction" letter for a typo should do the trick (see attached files). Look okay?

Joe - The ORC for Interface Fabrics called this morning with a question on the new permit that
became effective this month. The sample type for total arsenic and lead is listed as "grab". They were
composite in the previous permit. Is an amendment letter possible to correct the sample type? Let me
know. Thanks, Mike.
