Land Application of Sludge
Catawba County
Dear Mr. Beasley:
In accordance with your application for the renewal of Permit Number 13317 received November
9, 1990, we are forwarding herewith Permit No. WQ0004381, dated September 23, 1991, to the City of
Conover for the continued operation of a land application of sludge program.. As you requested, all
previously permitted sites except the Jim Robinson property have been deleted from the permit.
Please be advised, the disposal sites permitted herein may not be adequate for the disposal of all
sludges generated by the City's wastewater treatment facilities. The City should seek additional disposal
sites and/or an alternate disposal method immediately. Also, this permit requires that all sludges included
in this permit must be stabilized by a process to significantly reduce pathogens (as described in 40 CFR
Part 257, Appendix II) prior to land application or incorporation. Sufficient information to clearly
demonstrate that the City can meet this requirement has not been provided. You must provide this
information within six months (see condition 1-10). Should you desire to modify this permit in any way
(including the addition of disposal sites), you must clearly demonstrate that all sludges will be. stabilized as
required by 40 CFR Part 257, Appendix 11 prior to issuance of a modified permit.
This permit shall be effective from the date of issuance until August 31, 1996, and shall be subject
to the conditions and limitations as specified therein. Please pay particular attention to the monitoring
requirements in this permit. Failure to establish an adequate system for collecting and maintaining the
required operational information will result in future compliance problems.
