SUMMARY ? _
The Town of Mars Hill (1,900 pop.) operates a 0.425 MGD secondary wastewater treatment
facility that discharges into Gabriel Creek, which is a tributary to the French Broad River. ' The
Mars Hill Facility consists of a extended aeration package plant with a new Mechanical Spiral
Screen which replaced the existing Manual Influent screen, grit removal chamber, flow meter
with totalizer, three aeration basins, clarifier, aerobic digester with sludge return, chlorine
contact chamber, sludge drying beds and stand-by power (diesel generator). The facility also
utilizes land application for its bio-solids under WQ 0004298.
The Average Daily Flows reported from the facility DMR's were as follows: in 2002 = 0.15446
mgd, 2003 = 0.16562 and 2004 = 0.16746. On 6-30-05 the Departments construction and
Grants program acknowledged receipt of an Authorization to Construct application to
expand/improve the existing WWTP.
Use support ratings were assigned for waters in Subbasin 04-03-04 in the aquatic life,
recreation, fish consumption and water supply categories. All waters are No Data on an
evaluated basis in fish consumption because there are no fish consumption advisories in this
Subbasin. In the water supply category, all waters are Supporting on an evaluated basis based
on reports from DEH regional water treatment plant consultants.
TOXICITY TESTING:
There has been no WET testing requirement in the existing permit and none is anticipated for
this permit renewal.
COMPLIANCE SUMMARY: BASED ON THE PREVIOUS 2 YEARS
File search indicates the facility has had no DMR violations.
INSTREAM MONITORING:
Upstream and downstream monitoring for DO and Temperature are in the existing permit and
will be included in this renewal permit.

NPDES Permit NCO057151
Town of Mars Hill
Madison County
The Town of Mars Hill would like to request the renewal of its wastewater treatment
plant permit (NPDES Permit NCO057151). There has been one minor change in
treatment process or plant design from the last permit. At our influent we have replaced
our manual bar screen with a mechanical spiral screen to remove screenings from our
influent flow. Our facility has an excellent record of compliance and is still well below it
designed flow capacity. If you have any questions feel free to call me at [phone]
or my work Cell # [phone] and my email is [e-mail].

Sludge Management Plan
Our sludge management consists of a 44,750 gallon aerobic digester and 6 drying beds
each with a surface area of approximately 1,350 SF. All residuals will be stabilized by
aerobic digestion to significantly reduce pathogens (as described in 40 CFR Part 257,
Appendix 2) prior to application. The sludge is then surface applied on 18.8 acres on the
Larry Cody Farm (Permit # WQ0004298).
