Ms. Thedford,
This letter serves as the sludge management plan for the town of Troy (Permit #NC0028916)
Solids are routinely wasted into an aerated holding tank until full. Solids are then transferred to
a larger aerobic digester for long term storage(winter months). Normally, from May through
October the solids are dried using an on-site centrifuge and hauled to Republic Services landfill
located in Troy NC.
Should you need any additional infotijiation or clarification, please don't hesitate to call.

PART E. TOXICITY TESTING DATA
POTWs meeting one or more of the following criteria must provide the results of whole effluent toxicity tests for acute or chronic toxicity for each of the
facility's discharge points: 1)POTWs with a design flow rate greater than or equal to 1.0 mgd;2)POTWs with a pretreatment program(or those that are
required to have one under 40 CFR Part 403);or 3)POTWs required by the permitting authority to submit data for these parameters.
• At a minimum,these results must include quarterly testing for a 12-month period within the past 1 year using multiple species(minimum of two
species),or the results from four tests performed at least annually in the four and one-half years prior to the application,provided the results
show no appreciable toxicity,and testing for acute and/or chronic toxicity,depending on the range of receiving water dilution. Do not include
information on combined sewer overflows in this section. All information reported must be based on data collected through analysis conducted
using 40 CFR Part 136 methods. In addition,this data must comply with QA/QC requirements of 40 CFR Part 136 and other appropriate QA/QC
requirements for standard methods for analytes not addressed by 40 CFR Part 136.
• In addition,submit the results of any other whole effluent toxicity tests from the past four and one-half years. If a whole effluent toxicity test
conducted during the past four and one-half years revealed toxicity,provide any information on the cause of the toxicity or any results of a
toxicity reduction evaluation,if one was conducted.
• If you have already submitted any of the information requested in Part E,you need not submit it again. Rather,provide the information
requested in question E.4 for previously submitted information. If EPA methods were not used,report the reasons for using alternate methods.
If test summaries are available that contain all of the information requested below,they may be submitted in place of Part E.
If no biomonitoring data is required,do not complete Part E. Refer to the Application Overview for directions on which other sections of the form to
