Dear Mr. Corporon:
Upon review of the Draft NPDES Permit NC0085111, Heather Glen Subdivision,we offer the
following comments for your consideration:
1. Section 1-Process Components:No booster pumps to backwash storage tank exists on site.
We ask that this be removed.
2. Effluent Limitations and Monitoring Requirements: Sample collection is to be achieved by
composite collection. In the event that operation resumes in the future, sample collection
occurs only while filters are being backwashed. This process takes approximately 30 minutes
per filter and is done manually,making composite sampling nearly impossible, as there is no
steady stream of effluent over a long period of time. We ask that all collections be permitted
as grab samples.
3. Housekeeping Issues: J Bryce Mendenhall rather than Beyce, and Stephen Harrell rather
than Harwell.
Respectfully,
Dana Hill
