Dear Mr. Warren:
In accordance with your May 7, 2013 permit modification request, we are forwarding herewith
Permit No. WQ0036550, dated May 28, 2013, to Alan Smith for the distribution and marketing of a
fertilizer containing animal waste residuals which meet exceptional quality standards.
This permit shall be effective from the date of issuance until April 30, 2018; and shall be subject_
to the conditions and limitations as specified therein. Make note of this permit's expiration date and the
fact that a permit modification request is due to the Division of Water Quality (Division) no later than six
months prior to that date (i.e., see Condition V.7), as the Division does not send reminders to apply for
permit renewal. Be aware that payment of the annual administering and compliance fee, as stipulated in
Condition VA will not automatically renew this permit.
This permit approves the continued operation of the program for the distribution of a composted
fertilizer/soil amendment product, containing animal residuals, that meets exceptional quality standards
and is marketed throughout the State of North Carolina (i.e., in bulk and in bags) for another five-year
cycle. Note that this permit does not concurrently provide a license to distribute a fertilizer, as is required
by the Fertilizer Section of the NC Department of Agriculture and Consumer Services' Plant Industry
Division.. More information about applying for this license may be found at:
http://www.nea rg com/plantind/fert/ferties.htm.
The Division wants to remind you about the following issue that was discussed during the review
of this application:
♦ Conditions III.3 and IIIA require that the product be tested and monitored regularly for
specific parameters as well as for adequate pathogen reduction. It is imperative that all
testing and monitoring be performed such that the results are representative of the entire row
of product. The Division urges you to develop a set of standard operating procedures and
r6cordkeeping forms to ensure that the State of North Carolina time and temperature
requirements for the composting process are met.
