A. Engineering Calculations:
1. As per the DCAR 06-16 form submitted, in the residuals quality information, the amount of
residuals entered is 700 dry tons per year as compared to 3,400 in the previous permit. Please
provide a quantitative justification and calculation for the total residual tonnage to be certified.
B. Site Map:
1. As per 15A NCAC 02T .1104, for new and expanding residuals treatment and storage facilities:
2. Site plans. If required by G.S. 89C, a professional land surveyor shall provide location information
on boundaries and physical features not under the purview of other licensed professions. Site plans
or maps shall be provided to the Division by the applicant depicting the location, orientation, and
relationship of facility components, including:
 A scaled map of the site, with topographic contour intervals not exceeding 10 feet or 25
percent of total site relief and showing all facility-related structures and fences within the
treatment and storage areas;
 The location of each of the following that are located within 500 feet of a waste treatment,
or storage site, including a delineation of their review and compliance boundaries: (i) wells,
including usage and construction details if available; (ii) ephemeral, intermittent, and
perennial streams; (iii) springs; (iv) lakes; (v) ponds; and (vi) other surface drainage
features;
 Setbacks as required by Rule .1108 of this Section; and
 Site property boundaries within 500 feet of all treatment and storage facilities.
C. Operation & Maintenance Plan: Please submit an O & M plan in accordance with 15A NCAC 02T
.1110 that includes at a minimum:
1. Operational functions; describe the operation of the program to show what operations are

 Frequency and location of inspections, including those to be conducted by the ORC, and
procedures to assure that the selected location(s) and inspection frequency are
representative of the residuals management program.
 Detailed description of inspection procedures including record keeping and actions to be
taken by the inspector in the event that noncompliance is observed.
6. Sampling and monitoring plan including the following information;
 Names and titles of personnel responsible for conducting the sampling and monitoring.
 Detailed description of monitoring procedures including parameters to be monitored.
 Sampling frequency and procedures to assure that representative samples are being
collected. Fluctuation in temperature, flow, and other operating conditions can affect the
quality of the residuals gathered during a particular sampling event. The sampling plan
shall account for any foreseen fluctuations in residuals quality and indicate the most
limiting times for residuals to meet pathogen and vector attraction reduction requirements
(e.g. facilities that land apply multiple times per year but have an annual sampling
frequency, may need to sample during winter months when pathogen reduction is most
likely to be negatively affected by cold temperatures.
