PART IV - EVALUATION AND RECOMMENDATIONS
Upon verification that sludge is disposed of in accordance with NCGS 143-
215.1 and NCAC 2H.0200, reissue the permit.
In the applicant's cover letter for the permit application, he states, "If
sludge is removed, Mull's Septic Tank and Concrete Company of 2416 Mount Home
Church Road, Morganton, N. C. 28655 is contracted to do so. Mull's has a
permit with the state for disposal of sludge." During a telephone call to
Mull's on (November 2, 1994), this writer was told that all materials removed
from treatment plants serving the Caldwell County Schools (including
Collettsville) were transported to a farm and disposed of on Mull's permitted
site. Since Mull's does not hold a Land Application Permit from the EMC, the
site in question is assumed to be Mull's permitted septacte site, not a site
permitted for land application of wastewater sludges.
